References in this Annual Report on Form 20-F to “Mimecast Limited,” “we,” “our,” “us” and the “Company” refer to Mimecast Limited and its consolidated subsidiaries. Our consolidated financial statements are prepared in accordance with generally accepted accounting principles in the United States, or U.S. GAAP, and are expressed in U.S. dollars. References to “dollars” or “$” are to U.S. dollars. Our fiscal year ends on March 31 of each calendar year. References to any specific fiscal year refer to the year ended March 31 of the calendar year specified. For example, we refer to the fiscal year ending March 31, 20162017 as “fiscal 2016.2017.

The trademarks, trade names and service marks appearing in this Annual Report on Form 20-F are the property of their respective owners.

Certain amounts and percentages that appear in this Annual Report on Form 20-F have been subject to rounding adjustments. As a result, certain numerical figures shown as totals, including in tables, may not be exact arithmetic aggregations of the figures that precede or follow them.


Non-GAAP FinancialFinancial Measures

Revenue Constant Currency Growth Rate. In order to determine how our business performed exclusive of the effect of foreign currency fluctuations, we compare the percentage change in our revenue from one period to another using a constant currency. To determine the revenue constant currency growth rate for the fiscal years below, revenue from entities reporting in foreign currencies was translated into U.S. dollars using the comparable prior period’s foreign currency exchange rates. For example, the average rates in effect for the year ended March 31, 20152016 were used to convert revenue for the year ended March 31, 20162017 and the revenue for the comparable prior period ended March 31, 2015,2016, rather than the actual exchange rates in effect during the respective period. Revenue constant currency growth rate is a non-GAAP financial measure. A reconciliation of this non-GAAP measure to its most directly comparable U.S. GAAP measuresmeasure for the respective periods can be found in “Item 3—Key Information—A. Selected Consolidated Financial and Other Data” below.

The impact of foreign exchange rates is highly variable and difficult to predict. We use revenue constant currency growth rate to show the impact from foreign exchange rates on the current period revenue growth rate compared to the prior period revenue growth rate using the prior period’s foreign exchange rates. In order to properly understand the underlying business trends and performance of our ongoing operations, we believe that investors may find it useful to consider the impact of excluding changes in foreign exchange rates from our revenue growth rate.

We believe that presenting this non-GAAP financial measure in this reportAnnual Report on Form 20-F provides investors greater transparency to the information used by our management for financial and operational decision-making and allows investors to see our results “through the eyes” of management. We also believe that providing this information better enables our investors to understand our operating performance and evaluate the methodology used by management to evaluate and measure such performance.

However, this non-GAAP measure should not be considered in isolation or as a substitute for our financial results prepared in accordance with U.S. GAAP. For example, revenue constant currency growth rates, by their nature, exclude the impact of foreign exchange, which may have a material impact on U.S. GAAP revenue. Non-GAAP financial measures are not based on any comprehensive set of accounting rules or principles and therefore other companies may calculate similarly titled non-GAAP financial measures differently than we do, limiting the usefulness of those measures for comparative purposes.

Adjusted EBITDA. Adjusted EBITDA is a non-GAAP financial measure that we define as net (loss) income, adjusted to exclude: depreciation and amortization, share-based compensation expense, restructuring expense, interest income and interest expense, the provision for income taxes and foreign currency exchange income (expense). A reconciliation of this non-GAAP measure to its most directly comparable U.S. GAAP measuresmeasure for the respective periods can be found in “Item 3—Key Information—A. Selected Consolidated Financial and Other Data” below.

We believe that Adjusted EBITDA provides investors and other users of our financial information consistency and comparability with our past financial performance, facilitates period-to-period comparisons of operations and facilitates comparisons with our peer companies, many of which use a similar non-GAAP financial measure to supplement their GAAP results.

We use Adjusted EBITDA in conjunction with traditional GAAP operating performance measures as part of our overall assessment of our performance, for planning purposes, including the preparation of our annual operating budget, to evaluate the effectiveness of our business strategies, and to communicate with our board of directors concerning our financial performance.performance, and for establishing incentive compensation metrics for executives and other senior employees.

We do not place undue reliance on Adjusted EBITDA as a measure of operating performance. This non-GAAP measure should not be considered as a substitute for other measures of financial performance reported in accordance with GAAP. There are limitations to using a non-GAAP financial measure, including that other companies may calculate this measure differently than we do, that it does not reflect our capital expenditures or future requirements for capital expenditures and that it does not reflect changes in, or cash requirements for, our working capital.


SPECIAL NOTE REGARDING FORWARD-LOOKINGFORWARD-LOOKING STATEMENTS

This Annual Report on Form 20-F contains forward-looking statements within the meaning of the federal securities laws, which statements involve substantial risks and uncertainties. Forward-looking statements generally relate to future events or our future financial or operating performance.

Forward-looking statements contained in this Annual Report on Form 20-F include, but are not limited to, statements about:

our expectations regarding our revenue, expenses and other results of operations;

our plans to invest in sales and marketing efforts and expand our channel partnerships;

our ability to attract new customers and retain existing customers;

our anticipated strategies for growth;

our ability to anticipate market needs and develop new and enhanced solutions to meet those needs;

anticipated trends and challenges in our business and in the markets in which we operate;

our ability to compete in our industry and innovation by our competitors;

our ability to respond to evolving regulatory requirements regarding data protection and privacy; and

our plans to pursue strategic acquisitions.

We caution you that the foregoing list may not contain all of the forward-looking statements made in this Annual Report on Form 20-F.

You should not rely upon forward-looking statements as predictions of future events. We have based the forward-looking statements contained in this Annual Report on Form 20-F primarily on our current expectations and projections about future events and trends that we believe may affect our business, financial condition, operating results and prospects. The outcome of the events described in these forward-looking statements is subject to risks, uncertainties and other factors described in the “Item 3—Key Information—D. Risk Factors.” Moreover, we operate in a very competitive and rapidly changing environment. New risks and uncertainties emerge from time to time, and it is not possible for us to predict all risks and uncertainties that could have an impact on the forward-looking statements contained in this Annual Report on Form 20-F. We cannot assure you that the results, events and circumstances reflected in the forward-looking statements will be achieved or occur, and actual results, events or circumstances could differ materially from those described in the forward-looking statements.

The forward-looking statements made in this Annual Report on Form 20-F relate only to events as of the date on which the statements are made. We undertake no obligation to update any forward-looking statements made in this Annual Report on Form 20-F to reflect events or circumstances after the date of this Annual Report on Form 20-F or to reflect new information or the occurrence of unanticipated events, except as required by law. We may not actually achieve the plans, intentions, or expectations disclosed in our forward-looking statements and you should not place undue reliance on our forward-looking statements. Our forward-looking statements do not reflect the potential impact of any future acquisitions, mergers, dispositions, joint ventures, or investments we may make.

Basic and diluted net (loss) income per share applicable to ordinary shareholders is computed based on the weighted net-averageweighted-average number of ordinary shares outstanding during each period.

In order to determine how our business performed exclusive of the effect of foreign currency fluctuations, we compare the percentage change in our revenue from one period to another using a constant currency. To determine the revenue constant currency growth rate for the fiscal years below,each period, revenue from entities reporting in foreign currencies was translated into U.S. dollars using the comparable prior period’s foreign currency exchange rates. For example, the average rates in effect for the fiscal year ended to March 31, 20152016 were used to convert revenue for the year ended March 31, 20162017 and the revenue for the comparable prior period ended March 31, 2015,2016, rather than the actual exchange rates in effect during the respective period. Revenue constant currency growth rate is a non-GAAP financial measure. A reconciliation of this non-GAAP measure to its most directly comparable U.S. GAAP measuresmeasure for the respective periods can be found in the table below.

The impact of foreign exchange rates is highly variable and difficult to predict. We use revenue constant currency growth rate to show the impact from foreign exchange rates on the current period revenue growth rate compared to the prior period revenue growth rate using the prior period’s foreign exchange rates. In order to properly understand the underlying business trends and performance of our ongoing operations, we believe that investors may find it useful to consider the impact of excluding changes in foreign exchange rates from our revenue growth rate.

We believe that presenting this non-GAAP financial measure in this reportAnnual Report on Form 20-F provides investors greater transparency to the information used by our management for financial and operational decision-making and allows investors to see our results “through the eyes” of management. We also believe that providing this information better enables our investors to understand our operating performance and evaluate the methodology used by management to evaluate and measure such performance.

However, this non-GAAP measure should not be considered in isolation or as a substitute for our financial results prepared in accordance with U.S. GAAP. For example, revenue constant currency growth rates, by their nature, exclude the impact of foreign exchange, which may have a material impact on U.S. GAAP revenue. Non-GAAP financial measures are not based on any comprehensive set of accounting rules or principles and therefore other companies may calculate similarly titled non-GAAP financial measures differently than we do, limiting the usefulness of those measures for comparative purposes.

(4)

We calculate our revenue retention rate by annualizing revenue on a constant currency basis recorded on the last day of the measurement period for only those customers in place throughout the entire measurement period. We include add-on, or upsell, revenue from additional employees and services purchased by existing customers. We divide the result by revenue on a constant currency basis on the first day of the measurement period for all customers in place at the beginning of the measurement period. The measurement period is based on the trailing twelve months. The revenue on a constant currency basis is based on the average exchange rates in effect during the respective period.

(5)

Rounded up

Reflects the customer count on the last day of the period rounded to the nearest hundred customers.

(6)

Adjusted EBITDA is a non-GAAP financial measure that we define as net (loss) income, adjusted to exclude: depreciation and amortization, share-based compensation expense, restructuring expense, interest income and interest expense, the provision for income taxes and foreign currency exchange income (expense).

We believe that Adjusted EBITDA provides investors and other users of our financial information consistency and comparability with our past financial performance, facilitates period-to-period comparisons of operations and facilitates comparisons with our peer companies, many of which use a similar non-GAAP financial measure to supplement their GAAP results.

We use Adjusted EBITDA in conjunction with traditional GAAP operating performance measures as part of our overall assessment of our performance, for planning purposes, including the preparation of our annual operating budget, to evaluate the effectiveness of our business strategies, and to communicate with our board of directors concerning our financial performance.performance, and for establishing incentive compensation metrics for executives and other senior employees.

We do not place undue reliance on Adjusted EBITDA as a measure of operating performance. This non-GAAP measure should not be considered as a substitute for other measures of financial performance reported in accordance with GAAP. There are limitations to using a non-GAAP financial measure, including that other companies may calculate this measure differently than we do, that it does not reflect our capital expenditures or future requirements for capital expenditures and that it does not reflect changes in, or cash requirements for, our working capital.

Risks Related to Our Business and Our Industry

If we are unable to attract new customers and retain existing customers, our business and results of operations will be affected adversely.

To succeed, we must continue to attract new customers and retain existing customers who desire to use our security, continuity and archiving offerings. Acquiring new customers is a key element of our continued success, growth opportunity and future revenue. We will continue to invest in a direct sales force combined with a focused channel strategy designed to serve the various requirements of small, mid-market and large enterprises and to bring new customers onto our cloud architecture. Any failures by us to execute in these areas will negatively impact our business.  The rate at which new and existing customers purchase our products depends on a number of factors, including those outside of our control. For example, in the fiscal year ended March 31, 2017, we benefited from the decision by Intel Corporation to end-of-life its McAfee MX Logic email protection product.  Our future success also depends on retaining our current customers at acceptable retention levels. Our retention rates may decline or fluctuate as a result of a number of factors, some of which may be outside our control, including competition, customers’ budgeting and spending priorities, and overall general economic conditions. If our customers do not renew their subscriptions for our products and services, our revenue would decline and our business would suffer. In future periods, our total customers and revenue could decline or grow more slowly than we expect.

If we are unable to sell additional services and features to our existing customers, our future revenues and operating results will be harmed.

A significant portion of our revenue growth is generated from sales of additional services and features to existing customers. Our future success depends, in part, on our ability to continue to sell such additional services and features to our existing customers. We devote significant efforts to developing, marketing and selling additional services and features and associated support services to existing customers and rely on these efforts for a portion of our revenue. These efforts require a significant investment in building and maintaining customer relationships, as well as significant research and development efforts in order to provide upgrades and launch new services and features. The rate at which our existing customers purchase additional services and features depends on a number of factors, including the perceived need for additional security, continuity and archiving, the efficacy of our current services, the perceived utility of our new offerings, our customers’ IT budgets and general economic conditions. If our efforts to sell additional services and features to our customers are not successful, our future revenues and operating results will be harmed.

Failure to effectively expand our sales and marketing capabilities could harm our ability to acquire new customers and achieve broader market acceptance of our services.

Acquiring new customers and expanding sales to existing customers will depend to a significant extent on our ability to expand our sales and marketing operations. We generate approximately one-third of our revenue from direct sales and we expect to continue to rely on our sales force to obtain new customers and grow revenue from our existing customer base. We expect to expand our sales force in all of our regions and we face a number of challenges in achieving our hiring goals. For instance, there is significant competition for sales personnel with the sales skills and technical knowledge that we require. In addition, training and integrating a large number of sales and marketing personnel in a short period of time requires the allocation of significant internal resources. Our ability to achieve projected growth in revenue in the future will depend, in large part, on our success in recruiting, training and retaining sufficient numbers of sales personnel. We invest significant time and resources in training new sales personnel to understand our solutions and growth strategy. In general, new hires require significant training and substantial experience before becoming productive. Our recent hires and planned hires may not become as productive as we require, and we may be unable to hire or retain sufficient numbers of qualified individuals in the future in the markets where we currently operate or where we seek to conduct business. Our growth may be materially and adversely impacted if the efforts to expand our sales and marketing capabilities are not successful or if they do not generate a sufficient increase in revenue.


We have incurred losses in the past, and we may not be able to achieve or sustain profitability for the foreseeable future.

We have incurred significant losses in each period since our inception in 2003 up through our fiscal year ended March 31, 2014. In2017 with the exception of our fiscal year ended March 31, 2016, we incurred a net loss of $3.2 million. In our fiscal year ended March 31, 2015 in which we generated net income of $0.3 million. In our fiscal yearyears ended March 31, 2014,2017 and 2016, we incurred a net loss of $16.9 million.$5.4 million and $3.2 million, respectively. As of March 31, 2016,2017, we had an accumulated deficit of $88.6$94.0 million. We have been growing rapidly, and, as we do so, we incur significant sales and marketing, support and other related expenses. Our ability to achieve and sustain profitability will depend in significant part on our obtaining new customers, expanding our existing customer relationships and ensuring that our expenses, including our sales and marketing expenses and the cost of supporting new customers, does not exceed our revenue. We also expect to make significant expenditures and investments in research and development to expand and improve our services and technical infrastructure. In addition, as a public company, we willexpect to continue to incur significant legal, accounting and other expenses that we did not incur prior to our initial public offering in November 2015, we have not historically incurred as a private company.2015. These increased expenditures may make it harder for us to achieve and maintain profitability and we cannot predict when we will achieve sustained profitability, if at all. We also may incur losses in the future for a number of other unforeseen reasons. Accordingly, we may not be able to maintain profitability, once achieved, and we may incur losses in the foreseeable future.

FailureOur business depends substantially on customers renewing their subscriptions with us. A decline in our customer renewals would harm our future operating results.

In order for us to managemaintain or improve our growth effectively could increaseoperating results, it is important that our expenses, decreasecustomers renew their subscriptions with us when the existing subscription term expires. Although the majority of our customer contracts include auto-renew provisions, our customers have no obligation to renew their subscriptions upon expiration, and we cannot provide assurance that customers will renew subscriptions at the same or higher level of service, if at all. For each of the fiscal years ended March 31, 2017, 2016 and 2015, our customer retention rate has been consistently greater than 90%. We calculate customer retention rate as the percentage of paying customers on the last day of the relevant period in the prior year who remain paying customers on the last day of the relevant period in the current year. The rate of customer renewals may decline or fluctuate as a result of a number of factors, including our customers’ satisfaction or dissatisfaction with our solutions, the effectiveness of our customer support services, our pricing, the prices of competing products or services, mergers and acquisitions affecting our customer base, or reductions in our customers’ spending levels. If our customers do not renew their subscriptions, or renew on less favorable terms, our revenue and prevent us from implementing our business strategy.

We have been rapidly growing our revenue and number of customers,may decline, and we will seek to do the same for the foreseeable future. This rapid growth puts strain onmay not realize improved operating results from our business, requires significant capital expenditures and increases our operating expenses. To manage this growth effectively, we must attract, train and retain a significant number of qualified sales, implementation, customer service, software development, information

base.

technology and management personnel. In addition, as we grow our revenue and customer base, we will need to maintain and enhance our technology infrastructure, in particular, our data center capacity. If we fail to effectively manage our growth or we over-invest or under-invest in our business, our business and results of operations could suffer from the resulting weaknesses in our infrastructure, systems or controls. We could also suffer operational mistakes, loss of business opportunities and employee losses. If our management is unable to effectively manage our growth, our expenses might increase more than expected, our revenue could decline or grow more slowly than expected, and we might be unable to implement our business strategy.

The markets in which we participate are highly competitive, with several large established competitors, and our failure to compete successfully would make it difficult for us to add and retain customers and would reduce or impede the growth of our business.

Our market is large, highly competitive, fragmented and subject to rapidly evolving technology, shifting customer needs and frequent introductions of new products and services. We currently compete with companies that offer products that target email and data security, continuity and archiving, as well as large providers such as Google Inc. and Microsoft Corporation, which offer functions and tools as part of their core mailbox services that may be, or be perceived to be, similar to ours. Our current and potential future competitors include: Barracuda Networks, Inc., Google, Apps for Work, Microsoft Exchange Server, Exchange Online Protection, Proofpoint, Inc. and, Symantec Corporation and Cisco Systems Inc., in security MessageOne, in continuity,and Hewlett Packard Enterprise, Microsoft Office 365®, Symantec, and Barracuda HP Autonomy, Microsoft Office 365, Proofpoint and Symantec, in archiving. We expect competition to increase in the future from both existing competitors and new companies that may enter our markets. Additionally, some potential customers, particularly large enterprises, may elect to develop their own internal products. If two or more of our competitors were to merge or partner with one another, the change in the competitive landscape could reduce our ability to compete effectively. Our continued success and growth depends on our ability to out-perform our competitors at the individual service level as well as increasing demand for a unified service infrastructure. We cannot guarantee that we will out-perform our competitors at the product level or that the demand for a unified service technology will increase.

Some of our current competitors have, and our future competitors may have, certain competitive advantages such as greater name recognition, longer operating history, larger market share, larger existing user base and greater financial, technical and other resources. Some competitors may be able to devote greater resources to the development, promotion and sale of their products and services than we can to ours, which could allow them to respond more quickly than we can to new technologies and changes in customer needs. We cannot assure you that our competitors will not offer or develop products or services that are superior to ours or achieve greater market acceptance.

FailureData security and integrity are critically important to effectively expand our salesbusiness, and marketing capabilitiesbreaches of our information and technology networks and unauthorized access to a customer’s data could harm our abilitybusiness and operating results.

We have experienced, and will continue to acquire new customersexperience, cyberattacks and achieve broader market acceptanceother malicious internet-based activity, which continue to increase in sophistication, frequency and magnitude. Because our services involve the storage of large amounts of our services.customers’


sensitive and proprietary information, solutions to protect that information from cyberattacks and other threats, data security and integrity are critically important to our business. Despite all of our efforts to protect this information, we cannot provide assurance that systems that access our services and databases will not be compromised or disrupted, whether as a result of criminal conduct, distributed denial of service, or DDoS, attacks, such as the one we experienced in September 2015, or other advanced persistent attacks by malicious actors, including hackers, state-backed hackers and cybercriminals, breaches due to employee error or malfeasance, or other disruptions during the process of upgrading or replacing computer software or hardware, power outages, computer viruses, telecommunication or utility failures or natural disasters or other catastrophic events. Any breach of security, unauthorized access to or disclosure of confidential information, disruption, including DDoS attacks, or the perception that the confidential information of our customers is not secure, could result in a material loss of business, substantial legal liability or significant harm to our reputation.

AcquiringWe must continually monitor and develop our information technology networks and infrastructure to prevent, detect, address and mitigate the risk of unauthorized access. However, we may fail to identify these new customers and expanding salescomplex methods of attack, or fail to existing customers will dependinvest sufficient resources in security measures. In addition, as we increase our customer base and our brand becomes more widely known and recognized, we may become more of a target for malicious third parties. Any breach of our security measures as a result of third-party action, employee negligence and/or error, malfeasance, defects or otherwise that compromises the confidentiality, integrity or availability of our data or our customers’ data could result in:

severe harm to a significant extent onour reputation or brand, or materially and adversely affect the overall market perception of the security and reliability of our services;

individual and/or class action lawsuits, which could result in financial judgments against us and which would cause us to incur legal fees and costs;

legal or regulatory enforcement action, which could result in fines and/or penalties and which would cause us to incur legal fees and costs; and/or

additional costs associated with responding to the interruption or security breach, such as investigative and remediation costs, the costs of providing individuals and/or data owners with notice of the breach, legal fees, the costs of any additional fraud detection activities, or the costs of prolonged system disruptions or shutdowns.

Any of these events could materially adversely impact our business and results of operations.

Data privacy concerns, evolving regulations of cloud computing, cross-border data transfer restrictions and other domestic or foreign laws and regulations may limit the use and adoption of, or require modification of, our products and services, which could limit our ability to expandattract new customers or support existing customers thus reducing our revenues, harming our operating results and adversely affecting our business.

Laws and regulations related to the provision of services on the Internet are increasing, as federal, state and foreign governments continue to adopt new laws and regulations addressing data privacy and the collection, processing, storage and use of personal information. For example, in the United States, these include laws and regulations promulgated under the authority of the Federal Trade Commission, the Electronic Communications Privacy Act, the Computer Fraud and Abuse Act, the Health Insurance Portability and Accountability Act of 1996, or HIPAA, the Graham-Leach-Bliley Act of 1999, or Gramm-Leach-Bliley, and state breach notification laws, as well as regulator enforcement positions and expectations reflected in federal and state regulatory actions, settlements, consent decrees and guidance documents. Internationally, virtually every jurisdiction in which we operate has established its own data security and privacy legal frameworks with which we, or our customers, must comply, including the Data Protection Directive 95/46/EC, or the Directive, established in the European Union, or EU, and local EU Member State legislation implementing the Directive, such as the Data Protection Act in the United Kingdom which we refer to as the United Kingdom or the U.K.  Most recently, the EU adopted the EU General Data Protection Regulation, or GDPR, which will become effective in May 2018, increasing data security compliance obligations and consequences, including significant fines for organizations, located within or outside of the EU, when offering services in the EU. In October 2015, the European Court of Justice invalidated the U.S.-EU Safe Harbor framework that had been in place since 2000, which allowed companies to meet EU legal requirements for the transfer of personal data from the EU to the United States. While other adequate legal mechanisms to lawfully transfer such data remain, the invalidation of the U.S.-EU Safe Harbor framework may result in different European data protection regulators applying differing standards for the transfer of personal data to the United States. Such laws and regulations are subject to new and differing interpretations and may be inconsistent among jurisdictions. These and other regulatory requirements could restrict our ability to store and process data as part of our SaaS solutions, or, in some cases, impact our ability to offer our SaaS products in certain jurisdictions. Such laws may also impact our customers' ability to deploy certain of our solutions globally, to the extent they utilize our products for storing personal information that they store and process. In addition, in many cases these privacy laws apply not only to transfers of information to third parties, but also within an enterprise, including our company or our customers. Additionally, if third parties that we work with,


violate applicable laws or our policies, such violations may also put our customers’ information at risk and could in turn have an adverse effect on our business. The costs of compliance with, and other burdens imposed by, such laws, regulations and standards may require resources to create new products or modify existing products, lead to us being subject to significant fines, penalties or liabilities for noncompliance, and may slow the pace at which we close sales transactions, any of which could harm our business.

If we are unable to effectively increase sales of our services to large enterprises while mitigating the risks associated with serving such customers, our business, financial position and results of operations may suffer.

As we seek to increase our sales to large enterprise customers, we may face longer sales cycles, more complex customer requirements, substantial upfront sales costs and marketing operations. We generate approximately one-thirdless predictability in completing some of our revenue from direct sales than we do with smaller customers. In addition, our ability to successfully sell our services to large enterprises is dependent on us attracting and we expect to continue to rely on our sales force to obtain new customers and grow revenue from our existing customer base. We expect to expand our sales force in all of our regions and we face a number of challenges in achieving our hiring goals. For instance, there is significant competition forretaining sales personnel with the sales skills and technical knowledge thatexperience in selling to large organizations. Also, because security breaches of larger, more high-profile enterprises are likely to be heavily publicized, there is increased reputational risk associated with serving such customers. If we require. In addition, training and integrating a large number of sales and marketing personnel in a short time requires the allocation of significant internal resources. Our ability to achieve projected growth in revenue in the future will depend, in large part, on our success in recruiting, training and retaining sufficient numbers of sales personnel. We invest significant time and resources in training new sales personnel to understand our solutions and growth strategy. In general, new hires require significant training and substantial experience before becoming productive. Our recent hires and planned hires may not become as productive as we require, and we may beare unable to hire or retain sufficient numbersincrease sales of qualified

individuals in the future in the markets where we currently operate or where we seek to conduct business. Our growth may be materially and adversely impacted if the efforts to expand our sales and marketing capabilities are not successful or if they do not generate a sufficient increase in revenue.

If we are unable to maintain successful relationships with our channel partners, our ability to acquire new customers could be adversely affected.

In order to grow our business, we anticipate that we will continue to depend on our relationships with our channel partners who we rely on, in addition to our direct sales force, to sell and support our services. In our fiscal year ended March 31, 2016,2017, while no individual channel partner accounted for 10% or more of our sales, in the aggregate, our channel partners accounted 63%for 65% of our sales, and wesales. We expect that sales to channel partners will continue to account for a substantial portion of our revenue for the foreseeable future. We utilize channel partners to efficiently increase the scale of our marketing and sales efforts, increasing our market penetration to customers which we otherwise might not reach on our own. Our ability to achieve revenue growth in the future will depend, in part, on our success in maintaining successful relationships with our channel partners.

Our agreements with our channel partners are generally non-exclusive, meaning our channel partners may offer customers competitive services from different companies. If our channel partners do not effectively market and sell our services, choose to use greater efforts to market and sell their own products or services or those of others, or fail to meet the needs of our customers, our ability to grow our business, sell our services and maintain our reputation may be adversely affected. Our contracts with our channel partners generally allow them to terminate their agreements for any reason upon 90 days’ notice. The loss of key channel partners, our possible inability to replace them, or the failure to recruit additional channel partners could materially and adversely affect our results of operations. If we are unable to maintain our relationships with these channel partners, our business, results of operations, financial condition or cash flows could be adversely affected.

We provide service level commitments under our subscription agreements and service disruptions could obligate us to provide refunds and we could face subscription terminations, which could adversely affect our revenue.

Our subscription agreements with customers provide certain service level commitments. If we are unable to meet the stated service level commitments or suffer extended periods of downtime that exceed the periods allowed under our customer agreements, we could be required to pay refunds or face subscription terminations, either of which could significantly impact our revenue.

To date, we have suffered two significant service disruptions. The first occurred in 2013 and was a result of an equipment failure. Many of our customers in the United Kingdom experienced service disruptions for several hours. More recently, we experienced a service disruption onin September 21, 2015 as a result of an external network distributed denial of service, or DDoS attack. Customers using our Secure Email Gateway service in the United States experienced downtime related to the delivery and receipt of external emails for several hours. The scope of the incident was limited to network traffic and no customer data was lost or compromised. We incurred costs and expenses related to thisAs a result of the service disruption, including the voluntary payment ofwe voluntarily provided service credits to affected customers in the aggregate amountyear ended March 31, 2016, totaling approximately $0.4 million, all of $0.4 million.which were paid as of March 31, 2016. While we have undertaken substantial remedial efforts to prevent future incidents like these, we cannot guarantee that future attacks or service disruptions will not occur. Any future attacks or service disruptions could adversely affect our reputation, our relationships with our existing customers and our ability to attract new customers, all of which would impact our future revenue and operating results.

Our customers depend on our customer support team to resolve technical issues relating to our services. We may be unable to respond quickly enough to accommodate short-term increases in customer demand for support services. Increased customer demand for these services, without corresponding revenue, could increase costs and adversely affect our operating results. In addition, our sales process is highly dependent on the ease of use of our services, on our reputation and on positive recommendations from our


existing customers. Any failure to

maintain high-quality customer support, or a market perception that we do not maintain high-quality support, could adversely affect our reputation and our ability to sell our services to existing and prospective customers.

Our business depends substantially on customers renewing their subscriptions with us. A decline in our customer renewals would harm our future operating results.

In order for us to maintain or improve our operating results, it is important that our customers renew their subscriptions with us when the existing subscription term expires. Although the majority of our customer contracts include auto-renew provisions, our customers have no obligation to renew their subscriptions upon expiration, and we cannot provide assurance that customers will renew subscriptions at the same or higher level of service, if at all. For each of the fiscal years ended March 31, 2016, 2015 and 2014, our customer retention rate has been consistently greater than 90%. We calculate customer retention rate as the percentage of paying customers on the last day of the relevant period in the prior year who remain paying customers on the last day of the relevant period in the current year. The rate of customer renewals may decline or fluctuate as a result of a number of factors, including our customers’ satisfaction or dissatisfaction with our solutions, the effectiveness of our customer support services, our pricing, the prices of competing products or services, mergers and acquisitions affecting our customer base, or reductions in our customers’ spending levels. If our customers do not renew their subscriptions, or renew on less favorable terms, our revenue may decline, and we may not realize improved operating results from our customer base.

If we are unable to sell additional services and features to our existing customers, our future revenues and operating results will be harmed.

A significant portion of our revenue growth is generated from sales of additional services and features to existing customers. Our future success depends, in part, on our ability to continue to sell such additional services and features to our existing customers. We devote significant efforts to developing, marketing and selling additional services and features and associated support services to existing customers and rely on these efforts for a portion of our revenue. These efforts require a significant investment in building and maintaining customer relationships, as well as significant research and development efforts in order to provide upgrades and launch new services and features. The rate at which our existing customers purchase additional services and features depends on a number of factors, including the perceived need for additional security, continuity and archiving, the efficacy of our current services, the perceived utility of our new offerings, our customers’ IT budgets and general economic conditions. If our efforts to sell additional services and features to our customers are not successful, our future revenues and operating results will be harmed.

If we are not able to provide successful updates, enhancements and features to our technology to, among other things, keep up with emerging threatscyber-threats and customer needs, our business could be adversely affected.

Our industry is marked by rapid technological developments and demand for new and enhanced services and features to meet the evolving IT needs of organizations. In particular, cyber-threats are becoming increasingly sophisticated and responsive to the new security measures designed to thwart them. If we fail to identify and respond to new and increasingly complex methods of attack and update our products to detect or prevent such threats, our business and reputation will suffer. The success of any new enhancements, features or services that we introduce depends on several factors, including the timely completion, introduction and market acceptance of such enhancements, features or services. We may not be successful in either developing these modifications and enhancements or in bringing them to market in a timely fashion. Furthermore, modifications to existing technologies will increase our research and development expenses. If we are unable to successfully enhance our existing services to meet customer requirements, increase adoption and usage of our services, or develop new services, enhancements and features, our business and operating results will be harmed.

Data security and integrity are critically important to our business, and breaches of our information and technology networks and unauthorized access to a customer’s data could harm our business and operating results.

We have experienced, and will continue to experience, cyber-attacks and other malicious internet-based activity, which continue to increase in sophistication, frequency and magnitude. Because our services involve the storage of large amounts of our customers’ sensitive and proprietary information, solutions to protect that information from cyber-attacks and other threats, data security and integrity are critically important to our business. Despite all of our efforts to protect this information, we cannot provide assurance that systems that access our services and databases will not be compromised or disrupted, whether as a result of criminal conduct, DDoS attacks, such as the one we experienced in September 2015, or other advanced persistent attacks by malicious actors, including hackers, nation states and criminals, breaches due to employee error or malfeasance, or other disruptions during the process of upgrading or replacing computer software or hardware, power outages, computer viruses, telecommunication or utility failures or natural disasters or other catastrophic events. Any breach of security, unauthorized access to or disclosure of confidential information, disruption, including DDoS attacks, or the perception that the confidential information of our customers is not secure, could result in a material loss of business, substantial legal liability or significant harm to our reputation.

We must continually monitor and develop our information technology networks and infrastructure to prevent, detect, address and mitigate the risk of unauthorized access. However, we may fail to identify these new and complex methods of attack, or fail to invest sufficient resources in security measures. In addition, as we increase our customer base and our brand becomes more widely known and recognized, we may become more of a target for malicious third parties. Any breach of our security measures as a result of third-party action, employee negligence and/or error, malfeasance, defects or otherwise that compromises the confidentiality, integrity or availability of our data or our customers’ data could result in:

severe harm to our reputation or brand, or materially and adversely affect the overall market perception of the security and reliability of our services;

individual and/or class action lawsuits, which could result in financial judgments against us and which would cause us to incur legal fees and costs;

legal or regulatory enforcement action, which could result in fines and/or penalties and which would cause us to incur legal fees and costs; and/or

additional costs associated with responding to the interruption or security breach, such as investigative and remediation costs, the costs of providing individuals and/or data owners with notice of the breach, legal fees, the costs of any additional fraud detection activities, or the costs of prolonged system disruptions or shutdowns.

Any of these events could materially adversely impact our business and results of operations.

Because we recognize revenue from subscriptions for our services over the term of the agreement, downturns or upturns in new business may not be immediately reflected in our operating results and may be difficult to discern.

We generally recognize subscription revenue from customers ratably on a straight-line basis over the terms of their subscription agreements, which isare typically one year in duration. As a result, most of the revenue we report in each quarter is derived from the recognition of deferred revenue relating to subscription agreements entered into during the previous fiscal year or quarter. Consequently, a decline in new or renewed subscriptions with yearly terms in any one quarter may have a small impact on our operating revenue results for that quarter. However, such decline will negatively affect our revenue in future quarters. Accordingly, the effect of significant downturns in sales and market acceptance of our services, and potential changes in our pricing policies, rate of expansion or retention rate may not be fully reflected in our operating results until future periods. Shifts in the

mix of annual versus monthly subscription billings may also make it difficult to assess our business. We may also be unable to reduce our cost structure in line with a significant deterioration in sales. In addition, a significant majority of our costs are expensed as incurred, while revenue is recognized over the life of the agreement with our customer. As a result, increased growth in the number of our customers could continue to result in our recognition of more costs than revenue in the earlier periods of the terms of our agreements. Our subscription model also makes it difficult for us to rapidly increase our revenue through additional sales in any period, as revenue from new customers is recognized over the applicable subscription term.

Fluctuations in currency exchange rates could adversely affect our business.

Our functional currency and that of our subsidiaries is the local currency of each entity and our reporting currency is the U.S. dollar. In our fiscal year ended March 31, 2016, 37%2017, 50% of our revenue was denominated in U.S. dollars, 31% in British pounds, 44% in U.S. dollars, 16%15% in South African rand and 3%4% in other currencies. Given that our functional currency and that of our subsidiaries is the local currency of each entity, but our reporting currency is the U.S. dollar, fluctuations in currency exchange rates between the U.S. dollar, the British pound, the South African rand and the Australian dollar could materially and adversely affect our business. There may be instances in which costs and revenue will not be matched with respect to currency denomination. We estimate that a 10% increase or decrease in the value of the British pound against the U.S. dollar would have decreasedincreased or increaseddecreased our loss from operations by approximately $1.2 million in our fiscal year ended March 31, 20162017 and that a 10% increase or decrease in the value of the South African rand against the U.S. dollar would have increaseddecreased or decreasedincreased our loss from operations by approximately $1.3$1.7 million in our fiscal year ended March 31, 2016.2017. To date, we have not entered into any currency hedging contracts. As a result, to the extent we continue our expansion on a global basis, we expect that increasing portions of our revenue, cost of revenue, assets and liabilities will be subject to fluctuations in currency valuations. We may experience economic loss and a negative impact on earnings or net assets solely as a result of currency exchange rate fluctuations.

The United Kingdom held a referendum on June 23, 2016 in which a majority of voters approved an exit from the EU, or Brexit, and on March 29, 2017 the United Kingdom formally notified the EU of its intention to withdraw from the EU. A two-year period has now commenced during which the United Kingdom and the EU will negotiate the future terms of the United Kingdom's relationship with the EU, including, among other things, the terms of trade between the United Kingdom and the EU. The effects of Brexit will depend on any agreements the United Kingdom reaches to retain access to EU markets either during a transitional period or more permanently. The outcome of the referendum caused volatility in global stock markets and foreign currency exchange rate fluctuations, including the strengthening of the U.S. dollar against the British Pound and the euro, which may continue or worsen as the outcome of the negotiations becomes clear.


We are dependent on the continued services and performance of our two founders, the loss of either of whom could adversely affect our business.

Our future performance depends upon contributions from our senior management team and, in particular, our two founders, Peter Bauer, our Chairman and Chief Executive Officer, and Neil Murray, our Chief Technology Officer. If our senior management team, including any new hires that we may make, fails to work together effectively and to execute on our plans and strategies on a timely basis, our business could be harmed. The loss of one or more of our executive officers or key employees could have an adverse effect on our business. The loss of services of either Mr. Bauer or Mr. Murray could significantly delay or prevent the achievement of our development and strategic objectives.

We depend on highly skilled personnel to grow and operate our business, and if we are unable to hire, retain and motivate qualified personnel, we may not be able to grow effectively.

Our success depends largely upon our continued ability to identify, hire, develop, motivate and retain highly skilled personnel, including senior management, engineers, software developers, sales representatives and customer support representatives. Our growth strategy also depends, in part, on our ability to continue to attract and retain highly skilled personnel. Identifying, recruiting, training and integrating qualified individuals requires significant time, expense and attention of management. Competition for these personnel is intense, especially for engineers experienced in designing and developing software and software as a service, or SaaS, applications, and for experienced sales professionals. We have, from time to time experienced, and we expect to continue to experience, difficulty in hiring and retaining employees with appropriate qualifications. Many of the companies with which we compete for experienced personnel have greater resources than we have. If we hire employees from competitors or other companies, their former employers may assert that these employees or we have breached their legal obligations, resulting in a diversion of our time and resources. In addition, prospective and existing employees often consider the value of the equity awards they receive in connection with their

employment. If the actual or perceived value of our equity awards declines, or experiences significant volatility, it may adversely affect our ability to recruit and retain key employees. If we are not able to effectively recruit and retain qualified employees, our ability to achieve our strategic objectives will be adversely impacted, and our business will be harmed.

We are subject to a number of risks associated with global sales and operations.

We operate a global business with offices located in the United States, the United Kingdom, South Africa and Australia. In the fiscal year ended March 31, 2016,2017, we generated 39%49% of our revenue from the United Kingdom, 43%States, 33% from the United States, 16%Kingdom, 15% from South Africa and 2%3% from the rest of the world. As a result, our sales and operations are subject to a number of risks and additional costs, including the following:

fluctuations in exchange rates between currencies in the markets where we do business;

risks associated with trade restrictions and additional legal requirements, including the exportation of our technology that is required in some of the countries in which we operate;

greater risk of unexpected changes in regulatory rules, regulations and practices, tariffs and tax laws and treaties;

compliance with multiple anti-bribery laws, including the U.S.United States Foreign Corrupt Practices Act and the U.K. Anti-Bribery Act;

heightened risk of unfair or corrupt business practices in certain geographies, and of improper or fraudulent sales arrangements that may impact financial results and result in restatements of, or irregularities in, financial statements;

limited or uncertain protection of intellectual property rights in some countries and the risks and costs associated with monitoring and enforcing intellectual property rights abroad;

greater difficulty in enforcing contracts and managing collections in certain jurisdictions, as well as longer collection periods;

management communication and integration problems resulting from cultural and geographic dispersion;

social, economic and political instability, terrorist attacks and security concerns in general; and

potentially adverse tax consequences.

For example, Brexit may affect our results of operations in a number of ways, including increasing currency exchange risk, generating instability in the global financial markets or negatively impacting the economies of the United Kingdom or Europe.  In addition, because of our significant presence in the U.K., it is possible that Brexit may require us to restructure some or all of our operations. The long-term effects of Brexit will depend in part on any agreements the U.K. makes to retain access to markets in the


EU following the U.K.’s withdrawal from the EU. In addition, we expect that Brexit could lead to legal uncertainty and potentially divergent national laws and regulations as the U.K. determines which EU laws to replicate or replace. These and other factors could harm our ability to generate future global revenue and, consequently, materially impact our business, results of operations and financial condition.

These and other factors could harm our ability to generate future global revenue and, consequently, materially impact our business, results of operations and financial condition.

Any serious disruptions in our services caused by defects in our software or otherwise may cause us to lose revenue and market acceptance.

Our customers use our services for the most critical aspects of their business, and any disruptions to our services or other performance problems with our services, however caused, could hurt our brand and reputation and may damage our customers’ businesses. We provide regular updates, which may contain undetected errors when first introduced or released. In the past, we have discovered software errors, failures, vulnerabilities and bugs in our services after they have been released and new errors in our existing services may be detected in the future. Real or perceived errors, failures, system delays, interruptions, disruptions or bugs could result in negative publicity, loss of or delay in market acceptance of our services, loss of competitive position, delay of payment to us, lower renewal rates, or claims by customers for losses sustained by them. In such an event, we may be required, or may choose, for customer relations or other reasons, to expend additional resources in order to mitigate or correct the problem. We seek to cap the liability to which we are exposed in the event of losses or harm to our customers, but we cannot be certain that we will obtain these caps or that these caps, if obtained, will be respected in all instances. We carry insurance; however, the amount of such insurance may be insufficient to compensate us for any losses that may result from claims arising from defects or disruptions in our services. As a result, we could lose future sales and our reputation and our brand could be harmed.

If the prices we charge for our services are unacceptable to our customers, our operating results will be harmed.

As the market for our services matures, or as new or existing competitors introduce new products or services that compete with ours, we may experience pricing pressure and be unable to renew our agreements with existing customers or attract new customers at prices that are consistent with our pricing model and operating budget. If this were to occur, it is possible that we would have to change our pricing model or reduce our prices, which could harm our revenue, gross margin and operating results. Pricing decisions may also impact the mix of adoption among our subscription plans and negatively impact our overall revenue. Moreover, large enterprises, which may account for a larger portion of our business in the future, may demand substantial price concessions. If we are, for any reason, required to reduce our prices, our revenue, gross margin, profitability, financial position and cash flow may be adversely affected.

Our research and development efforts may not produce new services or enhancements to existing services that result in significant revenue or other benefits in the near future, if at all.

We invested 12% of our revenue in research and development in each of our fiscal yearyears ended March 31, 2017, 2016, 12% in our fiscal year ended March 31, 2015 and 15% in our fiscal year ended March 31, 2014.2015. We expect to continue to dedicate significant financial and other resources to our research and development efforts in order to maintain our competitive position. However, investing in research and development personnel, developing new services and enhancing existing services is expensive and time-consuming, and there is no assurance that such activities will result in significant new marketable services, enhancements to existing services, design improvements, cost savings, revenue or other expected benefits. If we spend significant time and effort on research and development and are unable to generate an adequate return on our investment, our business and results of operations may be materially and adversely affected.

We have acquired, and may acquire in the future, other businesses, which could require significant management attention, disrupt our business, dilute shareholder value and adversely affect our results of operations.

As part of our business strategy and in order to remain competitive, we may acquire, or make investments in, complementary companies, products or technologies. We have limitedFor example, in fiscal 2017, we acquired substantially all of the business of iSheriff, Inc., a cloud security provider.  Nevertheless, our acquisition experience to date remains limited, and as a result, our ability as an organization to acquire and integrate other companies, products or technologies in a successful manner is unproven. We may not be able to find suitable acquisition targets, and we may not be able to complete such acquisitions on favorable terms, if at all. If we do complete acquisitions, we may not ultimately strengthen our competitive position or achieve our goals, and any acquisitions we complete could be viewed negatively by our customers, analysts and investors. In addition, if we are unsuccessful at integrating such acquisitions or the technologies associated with such acquisitions, our revenue and results of operations could be adversely affected. In addition, while we will make significant efforts to address any information technology security issues with respect to any acquisitions, we may still inherit such risks when we integrate the acquired products and systems. Any integration process may require significant


time and resources, and we may not be able to manage the process successfully. We may not successfully evaluate or utilize the acquired technology or personnel, or accurately forecast the financial impact of an acquired business, including accounting charges. We may have to pay cash, incur debt or issue equity securities to pay for any such acquisitions, each of which could adversely affect our financial condition or the value of our ordinary shares. The sale of equity or issuance of debt to finance any such acquisitions could result in dilution to our shareholders. The incurrence of indebtedness would result in increased fixed obligations and could also include covenants or other restrictions that would impede our ability to manage our operations.

If the market for SaaS business software applications develops more slowly than we expect or declines, our business would be adversely affected.

The expansion of the SaaS business applications market depends on a number of factors, including the cost, performance and perceived value associated with SaaS, as well as the ability of SaaS providers to address data

security and privacy concerns. Additionally, government agencies have adopted, or may adopt, laws and regulations regarding the collection and use of personal information obtained from consumers and other individuals, or may seek to access information on our platform, either of which may reduce the overall demand for our platform. If we or other SaaS providers experience data security incidents, loss of customer data, disruptions in delivery, or other problems, the market for SaaS business applications, including our services, may be negatively affected.

If we are unable to effectively increase sales of our services to large enterprises while mitigating the risks associated with serving such customers, our business, financial position and results of operations may suffer.

As we seek to increase our sales to large enterprise customers, we may face longer sales cycles, more complex customer requirements, substantial upfront sales costs and less predictability in completing some of our sales than we do with smaller customers. In addition, our ability to successfully sell our services to large enterprises is dependent on us attracting and retaining sales personnel with experience in selling to large organizations. Also, because security breaches of larger, more high-profile enterprises are likely to be heavily publicized, there is increased reputational risk associated with serving such customers. If we are unable to increase sales of our services to large enterprise customers while mitigating the risks associated with serving such customers, our business, financial position and results of operations may suffer.

Natural disasters, power loss, telecommunications failures and similar events could cause interruptions or performance problems associated with our information and technology infrastructure that could impair the delivery of our services and harm our business.

We currently store our customers’ information within ten third-party data center hosting facilities located in ten locations around the world. As part of our current disaster recovery arrangements, our production environment and all of our customers’ data is currently replicated in near real-time in a facility located in a different location. We cannot assure youprovide assurance that the measures we have taken to eliminate single points of failure will be effective to prevent or minimize interruptions to our operations. Our facilities are vulnerable to interruption or damage from a number of sources, many of which are beyond our control, including floods, fires, power loss, telecommunications failures and similar events. They may also be subject to break-ins, sabotage, intentional acts of vandalism and similar misconduct. Any damage to, or failure of, our systems generally could result in interruptions in our service. Interruptions in our service may reduce our revenue, cause customers to terminate their subscriptions and adversely affect our renewal rate and our ability to attract new customers. Our business and reputation will also be harmed if our existing and potential customers believe our service is unreliable. The occurrence of a natural disaster, an act of terrorism, a decision to close the facilities without adequate notice or other unanticipated problems at these facilities could result in lengthy interruptions in our service. Even with the disaster recovery arrangements, our service could be interrupted. As we continue to add data centers and add capacity in our existing data centers, we may move or transfer our data and our customers’ data. Any unsuccessful data transfers may impair the delivery of our service. Further, as we continue to grow and scale our business to meet the needs of our customers, additional burdens may be placed on our hosting facilities.

Our existing credit agreement contains operating and financial covenants that may adversely impact our business and the failure to comply with such covenants could prevent us from borrowing funds and could cause any outstanding debt to become immediately payable.

Our existing credit agreement with Silicon Valley Bank contains operating and financial restrictions and covenants, including the prohibition of the incurrence of further indebtedness and liens, the prohibition of certain investments, the prohibition against paying dividends and redeeming or repurchasing capital stock, restrictions against merger and consolidation transactions and restrictions against the disposition of assets. This agreement requires us to maintain a minimum liquidity ratio and a minimum annual recurring revenue amount during its term, and is subject to acceleration upon a material change in control (as defined therein). These restrictions and covenants, as well as those contained in any future financing agreements that we may enter into, may restrict our

ability to finance our operations and to engage in, expand or otherwise pursue our business activities and strategies. Our ability to comply with these covenants may be affected by events beyond our control, and breaches of these covenants could result in a default under the credit agreement and any future financial agreements that we may enter into. If not waived, defaults could cause our outstanding indebtedness under our credit agreement and any future financing agreements that we may enter into to become immediately due and payable.

We employ third-party licensed software for use in or with our services, and the inability to maintain these licenses or errors in the software we license could result in increased costs, or reduced service levels, which would adversely affect our business.

Our services incorporate and rely on certain third-party software obtained under licenses from other companies. We anticipate that we will continue to rely on such third-party software and development tools in the future. Although we believe that there are commercially reasonable alternatives to the third-party software we currently license, this may not always be the case, or it may be difficult or costly to replace. In addition, integration of the software used in our services with new third-party software may require significant work and require substantial investment of our time and resources and delays in the release of our services until equivalent technology is either developed by us, or, if available, is identified, obtained and integrated, which could harm our business. A licensor may have difficulties keeping up with technological changes or may stop supporting the software or other intellectual property that it licensed to us. Also, to the extent that our services depend upon the successful operation of third-party software in conjunction with our software, any undetected errors or defects in this third-party software could prevent the deployment or impair the functionality of our services, delay new services introductions, result in a failure of our services, and injure our reputation. Our use of additional or alternative third-party software would require us to enter into additional license agreements with third parties on terms that may not be favorable to us.

Any failure to protect our intellectual property rights could impair our ability to protect our proprietary technology and our brand.

Our success and ability to compete depend in part on our intellectual property. We primarily rely on copyright, trade secret and trademark laws, trade secret protection and confidentiality or license agreements with our employees, customers, partners and others to protect our intellectual property rights. However, the steps we take to protect our intellectual property rights may be inadequate. As of March 31, 2016,2017, we had threehave 8 patents issued and 1114 patent applications pending in the United States. We also have one4 patents issued


and 5 patent issued and five applications pending for examination in non-U.S. jurisdictions, and four pending Patent Cooperation Treaty patent applications, all of which are counterparts of our U.S. applications.jurisdictions. We may not be able to obtain any further patents, and our pending applications may not result in the issuance of patents. We have issued patents and pending patent applications outside the United States, and we may have to expend significant resources to obtain additional patents as we expand our international operations due to the cost of monitoring and protecting our rights across multiple jurisdictions.

In order to protect our intellectual property rights, we may be required to spend significant resources to monitor and protect these rights. Litigation brought to protect and enforce our intellectual property rights could be costly, time-consuming and distracting to management and could result in the impairment or loss of portions of our intellectual property. Failure to adequately enforce our intellectual property rights could also result in the impairment or loss of those rights. Furthermore, our efforts to enforce our intellectual property rights may be met with defenses, counterclaims and countersuits attacking the validity and enforceability of our intellectual property rights. Patent, copyright, trademark and trade secret laws offer us only limited protection and the laws of many of the countries in which we sell our services do not protect proprietary rights to the same extent as the United States and Europe. Accordingly, defense of our trademarks and proprietary technology may become an increasingly important issue as we continue to expand our operations and solution development into countries that provide a lower level of intellectual property protection than the United States or Europe. Policing

unauthorized use of our intellectual property and technology is difficult and the steps we take may not prevent misappropriation of the intellectual property or technology on which we rely. For example, in the event of inadvertent or malicious disclosure of our proprietary technology, trade secret laws may no longer afford protection to our intellectual property rights in the areas not otherwise covered by patents or copyrights. Accordingly, we may not be able to prevent third parties from infringing upon or misappropriating our intellectual property. Our failure to secure, protect and enforce our intellectual property rights could materially adversely affect our brand and our business.

We may elect to initiate litigation in the future to enforce or protect our proprietary rights or to determine the validity and scope of the rights of others. That litigation may not be ultimately successful and could result in substantial costs to us, the reduction or loss in intellectual property protection for our technology, the diversion of our management’s attention and harm to our reputation, any of which could materially and adversely affect our business and results of operations.

We may be sued by third parties for alleged infringement of their proprietary rights.

There is considerable patent and other intellectual property development activity in our industry. Our success depends, in part, on our not infringing upon the intellectual property rights of others. Our competitors, as well as a number of other entities, including non-practicing entities, which are entities that have no operating business but exist purely as collectors of patents, and individuals, may own or claim to own intellectual property relating to our industry.

From time to time, certain third parties have claimed that we are infringing upon their intellectual property rights. In the future, we may be found to be infringing upon such rights. We closely monitor all such claims and none of the claims by the third parties have resulted in litigation, but legal actions by such parties are still possible. In addition, we cannot assure you that actions by other third parties alleging infringement by us of third-party patents or other intellectual property will not be asserted or prosecuted against us. In the future, others may claim that our services and underlying technology infringe or violate their intellectual property rights. We may also be unaware of the intellectual property rights that others may claim cover some or all of our technology or services. Any claims or litigation could cause us to incur significant expenses and, if successfully asserted against us, could require that we pay substantial damages or ongoing royalty payments, prevent us from offering our services, or require that we comply with other unfavorable terms. Under all of our sales contracts, we are obligated to indemnify our customers and channel partners against third-party infringement claims, and we may also be obligated to pay substantial settlement costs, including royalty payments, in connection with any such claim or litigation and to obtain licenses, modify services or refund fees, any of which could be costly. Even if we were to prevail in such a dispute, any litigation regarding intellectual property could be costly and time-consuming and divert the attention of our management and key personnel from our business operations.


Confidentiality arrangements with employees and others may not adequately prevent disclosure of trade secrets and other proprietary information.

We have devoted substantial resources to the development of our technology, business operations and business plans. In order to protect our trade secrets and proprietary information, we rely in significant part on confidentiality arrangements with our employees, licensees, independent contractors, advisers, channel partners, resellers and customers. These arrangements may not be effective to prevent disclosure of confidential information, including trade secrets, and may not provide an adequate remedy in the event of unauthorized disclosure of confidential information. In addition, if others independently discover trade secrets and proprietary information, we would not be able to assert trade secret rights against such parties. Effective trade secret protection may not be available in every country in which our services are available or where we have employees or independent contractors. The loss of trade secret protection could make it easier for third parties to compete with our solutions by copying functionality. In addition, any changes in, or unexpected interpretations of, the trade secret and employment laws in any country in which we operate may compromise our ability to enforce our

trade secret and intellectual property rights. Costly and time-consuming litigation could be necessary to enforce and determine the scope of our proprietary rights, and failure to obtain or maintain trade secret protection could adversely affect our competitive business position.

We may be subject to damages resulting from claims that our employees or contractors have wrongfully used or disclosed alleged trade secrets of their former employers or other parties.

We could in the future be subject to claims that employees or contractors, or we, have inadvertently or otherwise used or disclosed trade secrets or other proprietary information of our competitors or other parties. Litigation may be necessary to defend against these claims. If we fail in defending against such claims, a court could order us to pay substantial damages and prohibit us from using technologies or features that are essential to our solutions, if such technologies or features are found to incorporate or be derived from the trade secrets or other proprietary information of these parties. In addition, we may lose valuable intellectual property rights or personnel. A loss of key personnel or their work product could hamper or prevent our ability to develop, market and support potential solutions or enhancements, which could severely harm our business. Even if we are successful in defending against these claims, such litigation could result in substantial costs and be a distraction to management.

The use of open source software in our offerings may expose us to additional risks and harm our intellectual property.

Open source software is typically freely accessible, usable and modifiable. Certain open source software licenses require a user who intends to distribute the open source software as a component of the user’s software to disclose publicly part or all of the source code to the user’s software. In addition, certain open source software licenses require the user of such software to make any derivative works of the open source code available to others on unfavorable terms or at no cost. This can subject previously proprietary software to open source license terms.

We monitor and control our use of open source software in an effort to avoid unanticipated conditions or restrictions on our ability to successfully commercialize our products and solutions and believe that our compliance with the obligations under the various applicable licenses has mitigated the risks that we have triggered any such conditions or restrictions. However, such use may have inadvertently occurred in the development and offering of our products and solutions. Additionally, if a third-party software provider has incorporated certain types of open source software into software that we have licensed from such third-party, we could be subject to the obligations and requirements of the applicable open source software licenses. This could harm our intellectual property position and have a material adverse effect on our business, results of operations and financial condition.

The terms of many open source software licenses have not been interpreted by U.S. or foreign courts, and there is a risk that those licenses could be construed in a manner that imposes unanticipated conditions or restrictions on our ability to successfully commercialize our products and solutions. For example, certain open source software licenses may be interpreted to require that we offer our products or solutions that use the open source software for no cost; that we make available the source code for modifications or derivative works we create based upon, incorporating or using the open source software (or that we grant third parties the right to decompile, disassemble, reverse engineer, or otherwise derive such source code); that we license such modifications or derivative works under the terms of the particular open source license; or that otherwise impose limitations, restrictions or conditions on our ability to use, license, host, or distribute our products and solutions in a manner that limits our ability to successfully commercialize our products.

We could, therefore, be subject to claims alleging that we have not complied with the restrictions or limitations of the applicable open source software license terms or that our use of open source software infringes the intellectual property rights of a third-party. In that event, we could incur significant legal expenses, be subject

to significant damages, be enjoined from further sale and distribution of our products or solutions that use the open source software, be required to pay a license fee, be forced to reengineer our products and solutions, or be required to comply with the foregoing conditions of the open source software licenses (including the release of the


source code to our proprietary software), any of which could adversely affect our business. Even if these claims do not result in litigation or are resolved in our favor or without significant cash settlements, the time and resources necessary to resolve them could harm our business, results of operations, financial condition and reputation.

Additionally, the use of open source software can lead to greater risks than the use of third-party commercial software, as open source software does not come with warranties or other contractual protections regarding indemnification, infringement claims or the quality of the code.

We are a multinational organization faced with increasingly complex tax issues in many jurisdictions, and we could be obligated to pay additional taxes in various jurisdictions.

As a multinational organization, we may be subject to taxation in several jurisdictions around the world with increasingly complex tax laws, the application of which can be uncertain. The amount of taxes we pay in these jurisdictions could increase substantially as a result of changes in the applicable tax principles, including increased tax rates, new tax laws or revised interpretations of existing tax laws and precedents, which could have a material adverse effect on our liquidity and results of operations. In addition, the authorities in these jurisdictions could review our tax returns and impose additional tax, interest and penalties, and the authorities could claim that various withholding requirements apply to us or our subsidiaries or assert that benefits of tax treaties are not available to us or our subsidiaries. Furthermore, one or more jurisdictions in which we do not believe we are currently subject to tax payment, withholding, or filing requirements, could assert that we are subject to such requirements. Any of these claims or assertions could have a material impact on us and the results of our operations.

We are subject to governmental export controls and funds dealings restrictions that could impair our ability to compete in certain international markets and subject us to liability if we are not in full compliance with applicable laws.

Our software and services may be subject to export controls and we may also be subject to restrictions or prohibitions on transactions with, or on dealing in funds transfers to/from, certain embargoed jurisdictions and sanctioned persons and entities, pursuant to the U.K. Export Control Organisation’s restrictions, the U.K. Treasury’s restrictions, the EuropeanEU Council (EU) Regulations, the U.S.United States Department of Commerce’s Export Administration Regulations, the economic and trade sanctions regulations administered by the U.S.United States Treasury Department’s Office of Foreign Assets Controls and U.S.United States Department of State, and similar laws that may apply in other jurisdictions in which we operate or sell or distribute our services. Export control and economic sanctions laws include prohibitions on the sale or supply of certain products and services to certain embargoed or sanctioned countries, regions, governments, persons and entities, as well as restrictions or prohibitions on dealing in funds to/from those countries, regions, governments, persons and entities. In addition, various countries regulate the import of certain encryption items and technology through import permitting and licensing requirements, and have enacted laws that could limit our ability to distribute our services or could limit our customers’ ability to implement our services in those countries.

The exportation, re-exportation, and importation of our software and services, including by our channel partners, must comply with applicable laws or else we may be adversely affected, through reputational harm, government investigations, penalties, and/or a denial or curtailment of our ability to export our services. Although we take precautions to prevent our services from being provided in violation of such laws, our services may have been in the past, and could in the future be, provided in violation of such laws.

In 2008, an order was placed by a third-party U.K. reseller of Mimecast Services Limited, (“MSL”),or MSL, our U.K. operating company, for ongoing email archiving services to Persia International Bank, (“PIB”),or PIB, which is

based in London, United Kingdom. On July 27, 2010, PIB was named as a designated person on the EU Council Regulation against Iran. In March 2015, we determined that the provision of services after July 26, 2010 by MSL to PIB may have constituted an indirect breach by us of EU Council Regulation 267/2012. We terminated the PIB account with the U.K. reseller in April 2015 and also determined that no payments had been received by us from our channel partner related to this account since April 2014 and that the total revenue recognized by us over the life of the account was less than £12,500. On October 25, 2007, PIB had previously been included on the U.S. List of Specially Designated Nationals and Blocked Persons under Executive Order 13382. The designation was amended on August 16, 2010 to add a designation under the Iranian Financial Sanctions Regulations. In January 2016, the EU lifted the sanctions on PIB and its shareholder banks, Bank Mellat and Bank Tejarat. However, basedBased on our review, to date, because of the U.K. nexus to the activities, we believe this sale did not constitute a violation of U.S. trade sanctions administered by OFAC.United States Treasury’s Office of Foreign Asset Control. However, we may experience reputational harm as a result of the transaction by our U.K. operating company. We have since implemented additional export control compliance management oversight and have undertaken remedial measures and additional screenings to reduce the risk of similar events occurring in the future.

If we are found to be in violation of U.S. sanctions or export control laws, it could result in substantial fines and penalties for us and for the individuals working for us, including civil penalties of up to $250,000 or twice the value of the transaction, whichever is greater, per violation, and in the event of conviction for a criminal violation, fines of up to $1 million and possible incarceration for


responsible employees and managers for willful and knowing violations. Under the terms of applicable regulations, each instance in which a company provides goods or services may be considered a separate violation. If we are found to be in violation of U.K. sanctions or export controls, it could also result in unlimited fines for us and responsible employees and managers, as well as imprisonment of up to two years for responsible employees and managers.

Changes in our software or services, or changes in export, sanctions or import laws, may delay the introduction and sale of our services in international markets, prevent our customers with international operations from deploying our software or services or, in some cases, prevent the export or import of our software or services to certain countries, regions, governments, persons or entities altogether, which could adversely affect our business, financial condition and operating results.

Our quarterly results may fluctuate for a variety of reasons and may not fully reflect the underlying performance of our business.

Our quarterly operating results, including the levels of our revenue, gross margin, profitability, cash flow and deferred revenue, may vary significantly in the future, and period-to-period comparisons of our operating results may not be meaningful. Accordingly, the results of any one quarter should not be relied upon as an indication of future performance. Our quarterly financial results may fluctuate as a result of a variety of factors, many of which are outside of our control and, as a result, may not fully reflect the underlying performance of our business. Fluctuations in quarterly results may negatively impact the value of our ordinary shares. Factors that may cause fluctuations in our quarterly financial results include, but are not limited to:

foreign exchange rates;

our ability to attract new customers;

our revenue retention rate;

the amount and timing of operating expenses related to the maintenance and expansion of our business, operations and infrastructure;

network outages or security breaches;

general economic, industry and market conditions;

increases or decreases in the number of features in our services or pricing changes upon any renewals of customer agreements;

changes in our pricing policies or those of our competitors;

new variations in sales of our services, which has historically been highest in the fourth quarter of a given fiscal year; and

the timing and success of new services and service introductions by us and our competitors or any other change in the competitive dynamics of our industry, including consolidation among competitors, customers or strategic partners.partners; and

the impact of acquisitions.

Our credit agreement contains operating and financial covenants that may adversely impact our business and the failure to comply with such covenants could prevent us from borrowing funds and could cause any outstanding debt to become immediately payable.

Our credit agreement with Silicon Valley Bank contains operating and financial restrictions and covenants, including the prohibition of the incurrence of further indebtedness and liens, the prohibition of certain investments, the prohibition against paying dividends and redeeming or repurchasing capital stock, restrictions against merger and consolidation transactions and restrictions against the disposition of assets. This agreement requires us to maintain a minimum liquidity ratio and a minimum annual recurring revenue amount during its term, and is subject to acceleration upon a material change in control (as defined therein). These restrictions and covenants, as well as those contained in any future financing agreements that we may enter into, may restrict our ability to finance our operations and to engage in, expand or otherwise pursue our business activities and strategies. Our ability to comply with these covenants may be affected by events beyond our control, and breaches of these covenants could result in a default under the credit agreement and any future financial agreements that we may enter into. If not waived, defaults could cause our outstanding indebtedness under our credit agreement and any future financing agreements that we may enter into to become immediately due and payable. In addition, we have entered into capital lease agreements in the past and plan to enter into such agreements in the future.  These agreements may contain similar restrictions as the ones described above, which may impact the manner in which we operate our business.  


If we need to raise additional capital to expand our operations and invest in new technologies in the future and cannot raise it on acceptable terms or at all, our ability to compete successfully may be harmed.

We believe that our existing cash and cash equivalents will be sufficient to meet our anticipated cash requirements for at least the next twelve months. However, unforeseen circumstances may arise which may mean that we may need to raise additional funds, and we may not be able to obtain additional debt or equity financing on favorable terms, if at all. If we raise additional equity financing, our security holders may experience significant dilution of their ownership interests and the value of our ordinary shares could decline. If we engage in debt financing, we may be required to accept terms that restrict our ability to incur additional indebtedness, force us to maintain specified liquidity or other ratios or restrict our ability to pay dividends or make acquisitions. If we need additional capital and cannot raise it on acceptable terms, if at all, we may not be able to, among other things:

develop and enhance our services;

continue to expand our research and development, sales and marketing organizations;

hire, train and retain key employees;

respond to competitive pressures or unanticipated working capital requirements; or

pursue acquisition opportunities.

Our inability to do any of the foregoing could reduce our ability to compete successfully and harm our results of operations.

We are an “emerging growth company” and we cannot be certain whether the reduced requirements applicable to emerging growth companies will make our ordinary shares less attractive to investors.

We are an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act of 2012 effective on April 5, 2012, or the JOBS Act, and we may take advantage of certain exemptions from various requirements that are applicable to other public companies that are not emerging growth companies. Most of such requirements relate to disclosures that we would only be required to make if we cease to be a foreign private issuer in the future. Nevertheless, as a foreign private issuer that is an emerging growth company, we will not be required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002, or the Sarbanes-Oxley Act, for up to five fiscal years after the date of our initial public offering, which occurred in November 2015. We will remain an emerging growth company until the earliest of: (a) the last day of our fiscal year during which we have total annual gross revenue of at least $1.0 billion;billion (as may be inflation-adjusted by the Securities and Exchange Commission, or SEC, from time to time); (b) the last day of our fiscal year following the fifth anniversary of our initial public offering which occurred in November 2015; (c) the date on which we have, during the previous three-year period, issued more than $1.0 billion in non-convertible debt; or (d) the date on which we are deemed to be a “large accelerated filer” under the Securities Exchange Act of 1934, as amended, or the Exchange Act. When we are no longer deemed to be an emerging growth company, we will not be entitled to the exemptions provided in the JOBS Act discussed above. We cannot predict if investors will find our ordinary shares less attractive as a result of our reliance on exemptions under the JOBS Act. If some investors find our ordinary shares less attractive as a result, there may be a less active trading market for our ordinary shares and our share price may be more volatile.

Risks Related to Our Ordinary Shares and Our Organization in Jersey

Our share price has been and may continue to be volatile, and you may lose all or part of your investment.volatile.

The market price of our ordinary shares may decline.  In addition, the market price of our ordinary shares could be highly volatile and may fluctuate substantially as a result of a number ofmany factors, many of which we cannot control, including:

actual or anticipated fluctuations in our results of operations;

variance in our financial performance from the expectations of market analysts;

announcements by us or our competitors of significant business developments, changes in service provider relationships, acquisitions or expansion plans;

changes in the prices of our services or those of our competitors;

our involvement in litigation;

our sale of ordinary shares or other securities in the future;

market conditions in our industry;

changes in key personnel;


the trading volume of our ordinary shares;

the trading volume of our ordinary shares;

changes in the estimation of the future size and growth rate of our markets; and

general economic and market conditions.

In addition, the stock markets have experienced extreme price and volume fluctuations. Broad market and industry factors may materially harm the market price of our ordinary shares, regardless of our operating performance. In the past, following periods of volatility in the market price of a company’s securities, securities class action litigation has often been instituted against that company. If we were involved in any similar litigation we could incur substantial costs and our management’s attention and resources could be diverted.

If securities or industry analysts do notcease to publish research or publish inaccurate or unfavorable research about our business, our share price and trading volume could decline.

The trading market for our ordinary shares depends in part on the research and reports that securities or industry analysts publish about us or our business. If one or more of the analysts who covers us downgrades our shares or publishes inaccurate or unfavorable research about our business, our share price would likely decline. If one or more of these analysts ceases coverage of us or fails to publish reports on us regularly, demand for our shares could decrease, which could cause our share price and trading volume to decline.

We do not expect to pay dividends and investors should not buy our ordinary shares expecting to receive dividends.

We do not anticipate that we will declare or pay any dividends in the foreseeable future, and our ability to do so may be constrained by restrictions in our current and future debt arrangements and by Jersey law. Consequently, you will only realize an economic gain on your investment in our ordinary shares if the price appreciates. You should not purchase our ordinary shares expecting to receive cash dividends. Since we do not pay dividends, and if we are not successful in establishing an orderly trading market for our shares, then you may not have any manner to liquidate or receive any payment on your investment. Therefore our failure to pay dividends may cause you to not see any return on your investment even if we are successful in our business operations. In addition, because we do not pay dividends we may have trouble raising additional funds which could affect our ability to expand our business operations.

The market price of our ordinary shares could be negatively affected by future sales of our ordinary shares.

Sales by us or our shareholders of a substantial number of ordinary shares in the public market, or the perception that these sales might occur, could cause the market price of our ordinary shares to decline or could impair our ability to raise capital through a future sale of, or pay for acquisitions using, our equity securities.

As of March 31, 2016,We have filed with the holders of 29,366,099SEC a Registration Statement on Form F-3, commonly referred to as a “shelf registration,” that permits us to sell in a registered offering up to $50 million of our securities at our discretion.  The shelf registration was declared effective by the SEC on March 14, 2017.  While we have no current plans to conduct an offering of securities under the shelf registration statement, our plans could change at any time. In addition, the shelf registration statement also covers the registration of 20,539,030 ordinary shares held by our existing shareholders.  By agreement, these shareholders are entitled to demand that we register their shares under the Securities Act of 1933, as amended, or the Securities Act, for resale into the public markets. All shares sold pursuant tomarkets and they could affect their rights by requiring that we initiate an offering covered by suchunder the shelf registration statement will be freely transferable.statement.

In addition to our current shareholders’ registration rights and our existing shelf registration statement, as of March 31, 2016,2017, we had outstanding options and unvested restricted share units to purchase 8,069,8668,709,347 shares under our equity incentive plans and had an additional 5,999,3757,520,116 shares available for future grant.

As a foreign private issuer, we are permitted to follow certain home country corporate governance practices instead of otherwise applicable SEC and NASDAQ Stock Market, or NASDAQ, requirements, which may result in less protection than is accorded to investors under rules applicable to domestic U.S. issuers.

As a foreign private issuer, in reliance on the listing rules of NASDAQ, which permit a foreign private issuer to follow the corporate governance practices of its home country, we are permitted to follow certain Jersey corporate governance practices instead of those otherwise required under the corporate governance standards for U.S. domestic issuers. We currently do not, and do not intend to, take advantage of any such exemptions. We may in the future elect to follow Jersey home country practices with regard to matters such as the formation and composition of our board of directors, the compensation and nominating and corporate governance


committees, separate sessions of independent directors and the requirement to obtain shareholder approval for certain dilutive events (such as for the establishment or amendment of certain equity-based compensation plans, issuances that will result in a change of control of the company, certain transactions other than a public offering involving issuances of a 20% or more interest in the company and certain acquisitions of the stock or assets of another company).

Accordingly, our shareholders may not be afforded the same protection as provided under NASDAQ corporate governance rules that apply to U.S. domestic issuers. Following our home country governance practices as opposed to the requirements that would otherwise apply to a United States company listed on NASDAQ may provide less protection than is accorded to investors of domestic issuers.

As a foreign private issuer, we willare not be subject to the provisions of Regulation FD or U.S. proxy rules and will beare exempt from filing certain Exchange Act reports.

As a foreign private issuer, we are exempt from a number of requirements under U.S. securities laws that apply to public companies that are not foreign private issuers. In particular, we are exempt from the rules and regulations under the Exchange Act related to the furnishing and content of proxy statements, and our officers, directors and principal shareholders are exempt from the reporting and short-swing profit recovery provisions contained in Section 16 of the Exchange Act. In addition, we are not required under the Exchange Act to file annual and current reports and financial statements with the SEC as frequently or as promptly as U.S. domestic companies whose securities are registered under the Exchange Act and we are generally exempt from filing quarterly reports with the SEC under the Exchange Act. We are also exempt from the provisions of Regulation FD, which prohibits the selective disclosure of material nonpublic information to, among others, broker-dealers and holders of a company’s securities under circumstances in which it is reasonably foreseeable that the holder will trade in the company’s securities on the basis of the information. Even though we intendit is our policy to comply voluntarily with Regulation FD, these exemptions and leniencies will reduce the frequency and scope of information and protections to which you are entitled as an investor.

We are not required to comply with the proxy rules applicable to U.S. domestic companies, including the requirement applicable to emerging growth companies to disclose the compensation of our Chief Executive Officer and the other two most highly compensated executive officers on an individual, rather than an aggregate, basis.

We would lose our foreign private issuer status if a majority of our directors or executive officers are U.S. citizens or residents and we fail to meet additional requirements necessary to maintain foreign private issuer status. Although we have elected to comply with certain U.S. regulatory provisions, our loss of foreign private issuer status would make such provisions mandatory. The regulatory and compliance costs to us under U.S. securities laws as a U.S. domestic issuer may be significantly higher. If we are not a foreign private issuer, we will be required to file periodic reports and registration statements on U.S. domestic issuer forms with the SEC, which are more detailed and extensive than the forms available to a foreign private issuer. We would also be required to follow U.S. proxy disclosure requirements, including the requirement to disclose more detailed information about the compensation of our senior executive officers on an individual basis. We may also be required to modify certain of our policies to comply with good governance practices associated with U.S. domestic issuers. Such conversion and modifications will involve additional costs. In addition, we would lose our ability to rely upon exemptions from certain corporate governance requirements on U.S. stock exchanges that are available to foreign private issuers.

We expect to lose our foreign private issuer status effective April 1, 2018, which would then require us to comply with the Exchange Act’s domestic reporting regime and cause us to incur significant legal, accounting and other expenses.

We are currently a foreign private issuer and, therefore, we are not required to comply with all of the periodic disclosure and current reporting requirements of the Exchange Act applicable to U.S. domestic issuers. In order to maintain our current status as a foreign private issuer, either (a) a majority of our ordinary shares must be either directly or indirectly owned of record by non-residents of the United States or (b) (i) a majority of our executive officers or directors may not be United States citizens or residents, (ii) more than fifty-percent (50%) of our assets cannot be located in the United States and (iii) our business must be administered principally outside the United States. A foreign private issuer must determine its status on the last business day of its most recently completed second fiscal quarter which in our case is September, and a change in status (if any) would take effect as of the first day of the following fiscal year. We expect to lose our status as a foreign private issuer following the fiscal year ending March 31, 2017. If a foreign private issuer no longer satisfies these requirements, it will become subject to U.S. domestic reporting requirements on the first day of its fiscal year immediately succeeding such determination. If weWe expect to lose this status as of April 1, 2018 and, accordingly, we wouldwill be required to comply with the Exchange Act reporting and other requirements applicable to U.S. domestic issuers, which are more detailed and extensive than the requirements for foreign private issuers. We maywill also be required to make changes in our corporate governance practices in accordance with various SEC and NASDAQ rules. The regulatory and compliance costs to us under U.S. securities laws if we are required to comply with the reporting requirements applicable to a U.S. domestic issuer may be significantly higher than the cost we would incur as a foreign private issuer. As a result, we expect that athe loss of foreign private issuer status wouldwill increase our legal and financial compliance costs and wouldwill make some activities highly time consuming and costly.


We also expect that if we were required to comply with the rulesmust maintain proper and regulations applicable to U.S. domestic issuers, it would make it more difficult and expensive for us to obtain director and officer liability insurance, and we may be required to accept reduced coverage or incur substantially higher costs to obtain coverage. These rules and regulations could also make it more difficult for us to attract and retain qualified members to our board of directors.

We have not yet determined whether our existingeffective internal controls over financial reporting systems are compliant with Section 404and any failure to maintain the adequacy of the Sarbanes-Oxley Act, and we cannot provide any assurance that there are no material weaknesses or significant deficienciesthese internal controls may adversely affect investor confidence in our existing internal controls.company and, as a result, the value of our ordinary shares.

PursuantWe are required, pursuant to Section 404 of the Sarbanes-Oxley Act and the related rules adopted by the SEC, and the Public Company Accounting Oversight Board, starting with the second annualto furnish a report that we file with the SEC after our

initial public offering, ourby management will be required to report on, among other things, the effectiveness of our internal control over financial reporting on an annual basis. This assessment includes disclosure of any material weaknesses identified by our management in our internal control over financial reporting. During the evaluation and testing process, if we identify one or more material weaknesses in our internal control over financial reporting, we will be unable to assert that our internal controls are effective.

In addition, once we no longer qualify as an “emerging growth company” under the JOBS Act and lose the ability to rely on the exemptions related thereto discussed above, our independent registered public accounting firm will also need to attest to the effectiveness of our internal control over financial reporting under Section 404.404 which will lead to increased costs. Our independent registered public accounting firm may issue a report that is adverse in the event it is not satisfied with the level at which our controls are documented, designed or operating. We havemay not yet commenced the process of determining whether our existing internal controls over financial reporting systems are compliant with Section 404 and whether there arebe able to remediate any future material weaknesses, or to complete our evaluation, testing and any required remediation in a timely fashion. We are also required to disclose significant deficiencieschanges made in our existing internal controls. This process will require the investment of substantial time and resources, including by our chief financial officer and other members of our senior management. In addition, we cannot predict the outcome of this determination and whether we will need to implement remedial actions in order to implement effective control over financial reporting. The determination and any remedial actions required could result in us incurring additional costs that we did not anticipate. Irrespective ofprocedures on a quarterly basis.

As a result, we may experience higher than anticipated operating expenses during and after the implementation of these changes.operations. If we are unable to implement any of the required changes toassert that our internal control over financial reporting effectivelyis effective or efficiently or are required to do so earlier than anticipated, it could adversely affect our operations, financial reporting and/or results of operations and could result in an adverse opinion on internal controls from our independent registered public accounting firm.firm is unable to express an opinion on the effectiveness of our internal controls when it is required to issue such opinion, we could lose investor confidence in the accuracy and completeness of our financial reports, the market price of our ordinary shares could decline, and we could be subject to sanctions or investigations by NASDAQ, the SEC or other regulatory authorities.

A change in our tax residence could have a negative effect on our future profitability.

Although we are organized under the laws of Jersey, our affairs are, and are intended to continue to be, managed and controlled in the United Kingdom for tax purposes and therefore we are resident in the United Kingdom for U.K. and Jersey tax purposes. It is possible that in the future, whether as a result of a change in law or the practice of any relevant tax authority or as a result of any change in the conduct of our affairs or for any other reason, we could become, or be regarded as having become, a resident in a jurisdiction other than the United Kingdom. If we cease to be a U.K. tax resident, we may be subject to a charge to U.K. corporation tax on chargeable gains on our assets and to unexpected tax charges in other jurisdictions on our income. Similarly, if the tax residency of any of our subsidiaries were to change from their current jurisdiction for any of the reasons listed above, we may be subject to a charge to local capital gains tax on the assets.

Taxing authorities could reallocate our taxable income among our subsidiaries, which could increase our consolidated tax liability.

We conduct operations world-wide through subsidiaries in various tax jurisdictions pursuant to transfer pricing arrangements between our company and its subsidiaries. If two or more affiliated companies are located in different countries, the tax laws or regulations of each country generally will require that transfer prices be the same as those between unrelated companies dealing at arms’arm’s length and that appropriate documentation is maintained to support the transfer pricing. While we believe that we operate in compliance with applicable transfer pricing laws and intend to continue to do so, our transfer pricing procedures are not binding on applicable tax authorities. If tax authorities in any of these countries were to successfully challenge our transfer prices as not reflecting arms’ length transactions, they could require us to adjust our transfer prices and thereby reallocate our income to reflect these revised transfer prices, which could result in a higher tax liability to us. In addition, if the country from which the income is reallocated does not agree with the reallocation, both countries could tax the same income, resulting in double taxation. If tax authorities were to allocate income to a higher tax jurisdiction, subject our income to double taxation or assess interest and penalties, it would increase our consolidated tax liability, which could adversely affect our financial condition, results of operations and cash flows. Double taxation should be mitigated in these circumstances where the affiliated parties that are subject to the transfer pricing adjustments are able to benefit from any applicable double taxation agreement.


Our ability to use our U.S. net operating loss carry forwards may be subject to limitation.

As of March 31, 2016,2017, we had approximately $23.7 million, $28.0 million, $18.9 million, and $11.9 million in U.K., U.S. federal, U.S. state, and Australia net operating losses, of approximately $31.5 million, U.S. state net operating losses of approximately $24.4 million, and non-U.S. net operating losses of approximately $18.0

million.respectively. As of March 31, 2016,2017, we also had a $0.3 million U.K. income tax credit carryforward of $0.2 million. Also, eachand a $0.1 million US income tax credit carryforward. Each jurisdiction in which we operate may have its own limitations on our ability to utilize net operating losses or tax credit carryovers generated in that jurisdiction. These limitationsjurisdiction that may increase our U.S. federal, state,U.K. and/or foreign income tax liability.

U.S. holders of our ordinary shares could be subject to material adverse tax consequences if we are considered a Passive Foreign Investment Company, or PFIC, for U.S. federal income tax purposes.

We do not believe that we were a PFIC for U.S. federal income tax purposes during the 2015 tax year ending March 31, 2017 and do not expect to be a PFIC for U.S. federal income tax purposes in the 2016 tax year. We also do not expect to become a PFIC in the foreseeable future, but the possible status as a PFIC must be determined annually and therefore may be subject to change. If we are at any time treated as a PFIC, such treatment could result in a reduction in the after-tax return to U.S. holders of our ordinary shares and may cause a reduction in the value of such shares. Furthermore, if we are at any time treated as a PFIC, U.S. holders of our ordinary shares could be subject to greater U.S. income tax liability than might otherwise apply, imposition of U.S. income tax in advance of when tax would otherwise apply and detailed tax filing requirements that would not otherwise apply. For U.S. federal income tax purposes, “U.S. holders” include individuals and various entities. A corporation is classified as a PFIC for any taxable year in which (i) at least 75% of its gross income is passive income or (ii) at least 50% of the average quarterly value of all its total gross assets is attributable to assets that produce or are held for the production of passive income. For this purpose, passive income includes certain dividends, interest, royalties and rents that are not derived in the active conduct of a trade or business. The PFIC rules are complex and a U.S. Holderholder of our ordinary shares is urged to consult its own tax advisors regarding the possible application of the PFIC rules to it in its particular circumstances. For information on the U.S. federal tax implications on U.S. holders, see “Item 10.—Additional Information—E. Taxation.”

U.S. shareholders may not be able to enforce civil liabilities against us.

A number of our directors and executive officers are not residents of the U.S., and all or a substantial portion of the assets of such persons are located outside the United States. As a result, it may not be possible for investors to effect service of process within the United States upon such persons or to enforce against them judgments obtained in U.S. courts predicated upon the civil liability provisions of the federal securities laws of the United States.

There is also a doubt as to the enforceability in England and Wales and Jersey, whether by original actions or by seeking to enforce judgments of U.S. courts, of claims based on the federal securities laws of the U.S. In addition, punitive damages in actions brought in the U.S. or elsewhere may be unenforceable in England and Wales and Jersey.

The rights afforded to shareholders are governed by Jersey law. Not all rights available to shareholders under English law or U.S. law will be available to shareholders.

The rights afforded to shareholders will be governed by Jersey law and by theour Articles of Association, and these rights differ in certain respects from the rights of shareholders in typical English companies and U.S. corporations. In particular, Jersey law significantly limits the circumstances under which shareholders of companies may bring derivative actions and, in most cases, only the corporation may be the proper claimant or plaintiff for the purposes of maintaining proceedings in respect of any wrongful act committed against it. Neither an individual nor any group of shareholders has any right of action in such circumstances. In addition, Jersey law does not afford appraisal rights to dissenting shareholders in the form typically available to shareholders of a U.S. corporation.

B. Business Overview

We are a leading global provider of next generationnext-generation cloud security and risk management services for corporate information and email. Our fully-integrated suite of proprietary cloud services protects customers of all sizes from the significant business and data security risks to which their email system exposes them. We protect customers from today’s rapidly changing threat landscape where email has become a powerful attack vector and data leak concern. We also mitigate the significant business disruption that email failure or downtime causes. In addition, our archiving services secure, store and manage critical corporate communications and information to address growing compliance and e-discovery requirements and enable customers to use this increasing archive of information to improve employee productivity.

Email is a critical tool for organizations of all sizes. Protecting and managing email has become more complicated due to expanding security and compliance requirements and the rapid increase in both the volume and the importance of the information transmitted via email. Organizations are increasingly at risk from security breaches of sensitive data as sophisticated email-based attacks or data leaks have become more common. Additionally, organizations are not just using email for communication, they are also increasing their use of email archives as an active repository of vital corporate information needed to meet compliance requirements and support employee productivity. As a result, email represents one of the highest concentrations of business risk that organizations may face.

Traditional approaches to addressing these risks have leftleave customers managing disparate point products from multiple vendors that are often hard to use, costly to manage, difficult to scale, can fail to fully address today’s increasing and rapidly changing threats, and limit the use of corporate information to enhance productivity. These approaches also suffer from inefficient over-provisioning because of the need to resource for occasional peak demand. The resulting infrastructure complexity caused by disparate products and legacy architectures also makes it difficult to move more IT workloads to the cloud, which continues to be an increasing priority of organizations of all sizes.

We developed our proprietary cloud architecture to offer customers comprehensive email security, continuity and archiving capabilities indelivered from a single serviceplatform that makes it easier for them to protect themselves effectively in a worsening and rapidly changing security and risk environment. Providing a fully-integrated service also simplifies ongoing management and service deployment. Customers can then decommission the often costly and complex point products and on-premises technology they have traditionally used to tackleaddress these risks. We also make it easier for customers to move more of their IT workloads to the cloud.

We serve approximately 18,00026,400 customers and protect millions of their employees across the world. Our service scales effectively to meet the needs of customers of all sizes and we have optimized our sales

organization and channel to address each segment effectively. We have more than 675900 employees in 9nine offices in the United States, the United Kingdom, AustraliaSouth Africa and South Africa.Australia.

Our net loss was $16.9 million in the fiscal year ended March 31, 2014.2017 and 2016, respectively.

Industry Background

Email is a critical tool for organizations of all sizes. Email also captures a comprehensive history of corporate activity, knowledge and data vital for day-to-day business operations and employee productivity, the full potential of which is only beginning to be realized.productivity. Consequently, email needs protection and the technology needed to do this has extended well beyond the mailbox itself to include additional security, continuity and archiving services, all of which have typically been offered by separate vendors with different approaches.


Email is Critical to all Organizations

Email continues to be the primary way organizations exchange information and communicate externally and internally. According to a 2015 report by The Radicati Group, Inc., employees spend 2.38 hours of their work day on email. They also predict that the number of business emails sent each day worldwide will grow from 112.5 billion in 2015 to 128.8 billion in 2019, and the number of business email users will grow from 922 million to over 1 billion in the same period. Every customer segment and region will experience growth.

Email is also a productivity tool highly valued by employees as evidenced by a December 2014 survey by Pew Research where corporate internet users ranked email as more important than any other communication tool, including the internet itself.

In addition, many other critical IT systems depend on email to operate effectively. For example, sales, customer relationship management, human resources, finance and marketing systems typically rely on email for workflow management, important notifications and other functions, making email continuity and disaster recovery technologies particularly vital to the overall operations of an organization.

The Amount of Critical and Sensitive Data in Email Archives is Growing Rapidly

TheAccording to the 2015 Radicati Group report, also predicts that the average email storage per business user will grow by 65% in the next four years.between 2016 and 2020. The value of this archive of sensitive corporate data contained in email grows with every email or file exchanged. Traditionally, protecting and storing this archive has been a priority for compliance or risk officers, but the email archive is increasingly being used by employees as their primary repository to save and access important information. A 2014December 2016 report by Gartner1 estimates that by 2019, 75%“by 2021, over 35% of organizationsemail archiving for regulatory compliance and retention management will treat archive data, includingbe done through the native email as an active data source and not simply as a separate repository to be viewed or searched periodically,platform, up from less than 10% today.

Actively

Actively managing these dramatically expanding email archives with traditional on-premises storage technology is costly, so organizations are turning to cloud-based services to meet their archiving needs. A 2014December 2016 report by Gartner1 states that archiving“archiving as a service (a.k.a. cloud archiving)SaaS) for messaging content has rapidly surpassed on-premises archiving as the preferred deployment model for most organizations. Gartner sees that 60% toover 70% of new or replacement email archiving implementations as being cloud-based.  Moreover, organizationsAging on-premises archiving platforms are increasingly requiringbeing replaced by more powerful capabilitiesmodern solutions, and migration from one archive to search their email archive in support ofanother, although difficult, has become commonplace.”

According to Forrester Research, Inc., e-discovery and employee productivity. 46% of respondentsis firmly on the technology manager’s radar.

for enterprise architects and technology decision-makers. Forty-Eight percent of surveyed North American and European security technology decision-makers cited e-discovery as “critical” or “high-priority”.

Email is a Primary Security Target for Advanced Cyber-AttacksCyberattacks

In recent years, there has been an increase in the number of high profile security breaches, data leaks, extortion and fraud attacks using email. Well organized and funded, including state-backed, hackers and cyber-criminalscybercriminals are targeting organizations to disrupt their operations, steal money and sensitive corporate data, and gain access to valuable intellectual property. Email is often the primary target for these external attacks as well as the source of damaging data leaks from insiders, whether accidental or malicious. According to the monitoring service breachlevelindex.com, there have been over three billion reported lost data records since 2013 globally.

Spear-phishing and other social engineering attacks using email have become a widespread and effective attack technique against organizations of all sizes. These attacks are designed to trick the recipient into sharing sensitive data or wiring funds as well as opening a malicious link or attachment leading to a malware infection. Many of the highest profile data breaches have been the result of phishing attacks, including the Anthem Healthcare breach in 2016, the Sony Entertainment attack in 2014 and the Home Depot breach in 2014, the Target attack in 2013 and the RSA attack in 2011.2014. More recently, business email compromise attacks (also known as CEO fraud or whaling) are becoming common. According to the FBI,Federal Bureau of Investigation, there were $2.3 billion in losses from these types of attacks reported from October 2013 to February 2016. These attacks are not limited to large enterprises. In 2015, Endurance International reported that 71% of small businesses have been the victim of phishing attacks.

In addition to advanced and targeted threats, spam and other email-based cyber scams remain a significant problem for organizations, especially as the volume of emails continues to increase. A 2015 report by Kaspersky stated that spam represented 67% of all email flows in 2014.

As a result of the widespread impact of phishing attacks, the disruption of spam and the magnitude of recent data breaches, organizations are elevating the priority of IT security projects.

Data Protection, Cybersecurity and Data Privacy are Key Compliance and Regulatory Concerns for all Organizations

Governments, regulators and industry groups globally continue to enact or amend legislation and standards regarding data protection, cybersecurity and data privacy. Examples of such laws in the United States include the Health Insurance Portability and Accountability Act of 1996 (HIPAA), theHIPAA, Graham-Leach-Bliley, Act of 1999 (GLBA) and the Sarbanes-Oxley Act of 2002.Act. Countries in Europe have each adopted their own laws under the Data Protection Directive adopted in 1995,


which is expected towill be superseded in the next two yearsMay 2018 by a single law under the European Data Protection Regulation.GDPR These laws place growing obligations on organizations of all sizes, particularly those in regulated industries, to store, protect, process, share and transmit data safely, or risk significant sanctions as well as the threat of civil litigation. In addition, email communications, and the data they contain, may need to be produced as evidence in litigation or may be necessary to address legal, regulatory or internal queries that may arise in the future. This makes secure email archiving and the ability to access and search data an increasingly critical requirement.

Restrictions IT Teams Put on Email Create New Security Risks

As employees seek to become more productive, exchange files and collaborate, email usage and archive sizes continue to grow, placing greater demands on email resources. Meanwhile, IT teams are under pressure to reduce storage costs and improve infrastructure performance, and this often leads them to take steps to limit unfettered usage of email. This can include blocking large file sending to avoid choking network traffic and putting a file size limit on inboxes to reduce storage infrastructure, which makes it difficult for employees to use the email archive as their primary communication and file store. The frustration this creates can cause employees to seek solutions outside the secure corporate network, such as Dropbox and other web-based file sharing sites, increasing the risk of data leakage and making it difficult for the compliance department to monitor data traffic within and outside the organization.

Email Downtime is Disruptive to Employee Productivity

Given the critical nature of email for business communication and the importance of the information archive, email outages have become increasingly disruptive and costly because of the resulting impact on employee productivity. Employees are accustomed to being “always on” and accessing their email and data from mobile phones, tablets and other handheld devices, in addition to desktop devices. According to a report by Osterman Research, Inc., email systems experience a 53-minute mean of unplanned downtime each month, or 10.6 hours each year. Osterman estimates that employees become 25% less productive when their email system is down. This impact is not only felt in an outage, since organizations also must plan for regular maintenance and schedule downtime usually after hours atwith resulting higher cost given overtime wages.labor costs.

IT Workloads, Including Business Productivity Tools, are Moving to the Cloud

Organizations of all sizes are adopting cloud-based technologies to reduce the cost and complexity of their IT infrastructure and increase performance and flexibility. A recent March 2017 Gartner reportsreport2states that 75%“through 2018, about 80% of organizations use public cloud services today, although sparingly, and 78% plan towill increase their investment in cloud services in the next three years. 91% of organizations across all industries plan to use external providers to help with cloud adoption. IT spending on public cloud infrastructure as a service (IaaS), platform as a service (PaaS), software as a service (SaaS) and business process as a service (BPaaS) is growing at a five-year compound annual growth rate of 18% through 2018, more than six times the growth rate ofservices despite moderate increases in overall IT spending generally—2.7%—over the same time period. spending.”

This trend is a continuation of the disruptive shift that is seen elsewhere in the application market as a number of high growth SaaS vendors like Salesforce.com, NetSuite, ServiceNow and Workday continue to attract critical IT workloads from on-premises technologies to the cloud. Leading cloud infrastructure vendors such as Amazon Web ServicesServices® and Microsoft AzureAzure® are also seeing significant growth as organizations of all sizes adopt their offerings.

As organizations consider which workloads to move to the cloud, IT teams are looking beyond moving infrastructure and looking to shift traditional productivity tools to Microsoft’sMicrosoft Office 365365® or Google Apps for Work. Gartner statesG-Suite from Google®. “Gartner estimates that “the proportionin the third quarter of 2016, 20% to 25% of business users were provisioned in(in whole or in part,part) with office system capabilities from the cloud, willincluding the hybrid deployments…” The November 2016 report3states they “expect this percentage to double by 2018 and grow from approximately 15% in 2015 to 60%, or approximately 700 million usersat least 70% by 2022.2021.

Business Email Mailboxes are Moving to the Cloud, but this Creates New Risks to Mitigate

While business email continues to grow, the number of on-premises mailboxes will decline as organizations put them into the cloud. Organizations that move their primary email service to Microsoft Office 365365® or Google face significant risks from their single vendor exposure as they depend on one company for a reliable service, comprehensive threat protection and guaranteed data integrity.

These risks will only increase as services like Microsoft Office 365365® become more popular over time. With more organizations relying on the same hosting infrastructure, any outage or downtime can cause severe industry-wide disruption. Also attacking Microsoft Office 365365® or Google is increasingly attractive for cyber criminals because they know they only have to find a way to attack the single security stack used by these hosting providers to access multiple targets. This attack scenario is easier and more efficient than targeting organizations one at a time.

As a result, we believe that most organizations prefer to have third-party security, continuity and archiving providers in place to reduce their risk posture and provide additional layers of redundancy and enhanced service quality. As organizations adopt cloud infrastructure services, they have also increasedincrease spending on securing these workloads with cloud-based security products.


Traditional Email Security, Continuity and Archiving Alternatives can be Inadequate and domay not Address Increasing Customer Requirements and Protect Againstagainst Next Generation Security Threats

As the threat landscape becomes more dynamic and complex, and customers want to put more critical IT workloads into the cloud, we believe the point products and traditional architectures that address email security, continuity and archiving will not be able to adequately address increasing customer requirements.

Point Products are Inflexible and only Address Part of the Problem

To address their security, continuity and archiving needs, many organizations have deployed a complex array of disparate or point products on-premises, or cloud-based versions hosted by the vendor.

These technologies are typically from multiple vendors, sometimes developed in-house or use features that shipped with the mail server and only address narrow uses and problems. They can be difficult to integrate, inflexible, unreliable, complex and expensive to manage, particularly as email and data volumes grow. The growing complexity associated with broader IT risks and the escalation of security threats requires a solution that is integrated and agile, and increasingly cloud-based as organizations move more IT workloads there. As a result, organizations who rely on traditional point products will struggle to adapt their infrastructure cost-effectively for today’s email requirements.

Traditional On-Premises or Hosted Architectures have Performance Limitations and are Expensive

Existing technologies, whether on-premises or hosted, are typically built on a single-tenant architecture, which requires extra provisioning to plan for occasional peak volumes and unplanned circumstances for each customer. This approach is inefficient and expensive as it requires a higher minimum investment for each implementation than a native cloud approach that utilizes pooled provisioning across multiple tenants. Hosted “cloud” versions of an on-premises approach rely on the same single-tenant IT architecture as the on-premises version that limits scalability, is inflexible, hard to update rapidly and more expensive to deploy and manage.

Large enterprises that have invested heavily in traditional on-premises technology to address their mounting email risks are increasingly finding themselves exposed as these systems are not adequate or agile enough to adapt to the evolving threat landscape. Smaller and mid-market organizations are also at risk and often more vulnerable as they lack the same level of IT resources or budgets to counter these threats with many having purchased limited security technology. In addition, many small businesses have poor cybersecurity, lacking things like anti-phishing email measures, a recent survey by Endurance, only 42%chief cybersecurity officer, data encryption, or off-site backups of small business owners had recently invested resources into any form of security protection, which may not be sufficient given the hostile threat landscape.their websites.

Organizations Need a New Approach to Email Security and Management

The limitations of traditional security and archiving technologies mean customers need to rethink their approach to protecting email and corporate information. Customers needwant to mitigate the risks they face from email, and want to reduce the overall cost and complexity, and move more of their workloads to the cloud.

According to the new Worldwide Semiannual Public Cloud Services Spending Guide from International Data Corporation, or IDC, worldwide spending on public cloud services will grow at a 19.4% compound annual growth rate -- almost six times the rate of overall IT spending growth – from nearly $70 billion in 2015 to more than $141 billion in 2019. The new spending guide expands on IDC's previous public cloud services forecasts by offering greater detail on industry and geographic spending levels.

SaaS, will remain the dominant cloud computing type, capturing more than two thirds of all public cloud spending through most of the forecast period.

We believe organizations are ultimately looking to implement a multi-layered cyber security and resilience strategy that delivers protection of users, data and operations from the risks arising from technological failure, human error and malicious intent. The risks also increase with organizations migrating to Microsoft Office 365365®, as it is a complex email solution that is a high value and high profile target. Organizations also need robust continuity options to solve for unpredictable events that cause an outage to email and result in disruption to business. A multi-layered cyber security and resilience approach is needed in order to address the diverse threats and diverse data classifications within a single data environment. Organizations also need robust continuity options to solve for unpredictable events that cause an outage to email and disruption to business.


Meeting this growing customer demand requires an email and data security cloud service that meets the following requirements:

Integrated Offering. By bringing multiple requirements into one unified service, the next-generation email service would help the organization reduce the complexity and cost of managing point technologies from disparate vendors and bring additional benefits from new capabilities made possible due to unification.

By bringing multiple requirements into one unified service, the next-generation email service would help the organization reduce the complexity and cost of managing point technologies from disparate vendors and bring additional benefits from new capabilities made possible due to unification.

Strong Technology. As organizations substitute specialized products provided by different vendors with a unified email service, it is imperative that the individual products are as good, or better, than those being replaced. Organizations are not willing to compromise on performance or security at a product level.

Native Cloud. As organizations shift workloads to the cloud, and move away from retaining on-premises or single tenant hosted cloud infrastructure, today’s email security and information management technology must be natively cloud-based eliminating the need for local software and hardware, virtual machines and device hosting.

Built for Scale. As email traffic and data storage continues to increase dramatically, the risk of threats escalates and the need for real-time, on-demand email access becomes more prominent, organizations cannot compromise on email performance and availability. The ideal solution must be easily scalable to match customer demand and be able to handle large volumes.

We believe our immediate opportunity is to replace incumbent email security, continuity and archiving vendors. As we extend our products into adjacent areas, we anticipate this will open up additional opportunities beyond this to take further market share in a wider range of enterprise security and data management markets. We also expect to benefit from the growing popularity of cloud email services, specifically Microsoft Office 365365® and Google, and the customer need for complementary security, archiving, back-up and continuity services.

Our Solution

Our fully-integrated suite of cloud services for security, continuity and archiving is designed to protect email and deliver comprehensive email risk management beyond the primary mail server. We protect customers from the growing threat from email and to the corporate data it contains from malware, spam, data leaks and advanced threats like spear-phishing. We also help organizations securely and cost effectively archive their growing email and file repositories to support employee productivity, compliance and e-discovery. Our continuity services ensure email and corporate information remain available in the event of a primary system failure or scheduled maintenance downtime.

Our customers benefit from:

Comprehensive Email and Data Risk Management in a Single, Unified Cloud Service. Our services integrate a range of technologies into a comprehensive service that would otherwise require an array of individual devices or services from multiple vendors. We enable customers to decommission these technologies, reduce the cost and complexity of their infrastructure, redeploy IT resources, and improve the security and risk management of their corporate email environment.

Best-of-Breed Security, Continuity and Archiving Services. We believe our customers should not have to compromise on the quality of their email security, continuity or archiving services in order to benefit from integration. Our strategy is to develop best-of-breed capabilities within our integrated service to compete successfully with industry-leading point products in three critical areas:

Email and Data Security: We protect customers from a comprehensive range of email and data related threats that include, but are not limited to, spam, viruses, phishing and spear phishing, identity theft, advanced persistent threats, malicious attachments, known and unknown malware, outbound spam outbreaks and malicious inbound URLs, extortion and fraud. We combine our proprietary cloud-based scanning, detection and real-time intelligence gathering technologies with third-party threat data and malware libraries to deliver comprehensive and overlapping protection reflective of a best-of-breed security service.

Email Service Continuity: Our continuity service enables customers to send, receive and view emails and calendars during email gateway failures or planned maintenance downtime, without the need to build or host their own replicated email environment. Our service has immediate fail-over and fail-back capabilities, and is fully-integrated into Microsoft Outlook®. Employees can continue to access their email and data using their preferred mobile, tablet or desktop device, or via our web-based portal, so there is limited interruption to how they normally operate.

Data Archiving: We enable organizations to archive rapidly growing volumes of email and associated data safely and centrally in the cloud to support their need to archive data cost effectively to meet long term storage, compliance, governance, risk mitigation and regulatory obligations. We also provide powerful search tools that can increase employee productivity, and enable them to utilize their archive as a live file store. Key features of our service include, unlimited and perpetual legal hold, discovery and early legal case assessment, onsite and cloud-linked retention management, administrator and employee-led retention controls, onsite and metadata synchronization and record destruction policies and services.

Web Scale Performance for Organizations of All Sizes. Our cloud service is built to address the most demanding scale, performance and availability requirements of large enterprises but delivers this as a subscription-based cloud service that puts these capabilities within the reach of small and mid-market organizations too. Our data centers process approximately 307 million emails per day, and store over 190 billion emails and approximately 28 petabytes of customer data. We achieve demanding continuity service commitments with data centers that are replicated in each geography and operate in active-active mode enabling fast failover and fail-back as required.

Compelling Return on Investment. Our unified, cloud-based service enables our customers to decommission a range of legacy and disparate technologies that support their email server and recover this cost. We utilize hardware efficiently, and share a single instance of the operating software as well as storage and processing hardware securely across the whole customer base within each data center, allowing us to deliver cloud-scale economic and performance benefits to our customers. Customers also benefit from the continuous improvement of our service without the need to pay for service packs or updates. Our service bundles and subscription-based pricing also enable customers to pay per employee and select their desired services making costs easy to predict and affordable.

Easy to Deploy and Manage. Our service is designed to be easier to deploy than alternative technologies. Customers simply route their email traffic through our cloud and can be up and running in a matter of days and sometimes less. We then enable our customers to add or delete new services and employees, and manage all security and other policies centrally via a single web-based administration console that significantly simplifies the ongoing management of their email and data environment.

Our Growth Strategy

We will continue to invest in extending our leadership in cloud security and risk management services, and asservices. As more organizations move IT workloads such as email to the cloud, we believe we are well positioned to continue capitalizing on this growing opportunity globally.

Our growth strategy is focused on the following:

Grow Revenue From Our Existing Customer Base. We serve approximately 26,400 customers of all sizes. We provide a high level of service that results in our customers staying with us year over year. This large and loyal customer base provides us with the opportunity to sell additional services and add more employees to their subscriptions. As a result, we have achieved a revenue retention rate of 111% and 109% for the fiscal years ended March 31, 2017 and 2016, respectively. As of March 31, 2017, 24% of our customers subscribed to one of our services, 25% of our customers subscribed to two of our services, 22% of our customers subscribed to three of our services, and 29% of our customers subscribed to four or more of our services. As of March 31, 2017, approximately 25,800 of our customers subscribed to our Email Security service, approximately 16,600 subscribed to our Mailbox Continuity service, and approximately 11,400 subscribed to our Enterprise Information Archiving service. As a result, we believe we have significant upsell potential in our existing customer base with current and new services. We intend to continue proactively broadening our reach within our existing customer base by selling additional services.

Acquire New Customers. We have built our global cloud architecture to offer best-of-breed capabilities and to be highly scalable and affordable for organizations of any size, ranging from small and mid-market customers to the largest global enterprises. Moreover, we offer our security, continuity and archiving email services as bundles and in a modular fashion, enabling us to win new customers by addressing a variety of initial needs and use cases that we expand over time as we cross sell other offerings. We will continue to invest in a direct sales force combined with a focused channel strategy designed to serve the various requirements of small, mid-market and large enterprises and to bring new customers onto our cloud architecture.

Actively Invest in Our Channel Partner Network. The majority of our sales are through a reseller channel designed specifically to meet the requirements of each of our target customer segments. In the large enterprise market, we are building on existing relationships with leading systems integrators such as CDW Corporation and Dimension Data. In small and mid-market organizations, we are extending our network of leading IT resellers like Softcat PLC, SHI International Corp., CDW and Softchoice Corporation. We expect to expand our channel strategy over time to incorporate additional security or cloud specialists, as well as resellers focusing on supporting customers with the transition to Microsoft Office 365®. We intend to further invest in our network of channel partners to further extend our global sales, service and support capabilities.

Develop Our Technology and Release New Services. We regularly update and improve our software and architecture and seamlessly deploy these updates to our customers. In the fiscal year ended March 31, 2016, we launched Impersonation Protect, the first service of its kind to protect against the growing threat from business email compromise (also known as CEO fraud or whaling) attacks. In the fiscal year ended March 31, 2017, we launched Internal Email Protect, which allows customers to monitor, detect and remediate security threats that originate from their internal email systems. We will continue to build on our current capabilities and exploit additional opportunities in adjacent areas to those we serve today. This will extend the value our customers can gain from our architecture and enable them to consolidate additional email and data services to our integrated cloud service working seamlessly with Microsoft Exchange®, Microsoft Office 365® and G-Suite from Google®.

Continue to Expand Our Geographic Presence. We were founded outside the United States and, consequently, 57%51% and 62%57% of our sales in fiscal years 20162017 and 2015,2016, respectively, were derived from non-U.S. locations. Revenue from the United States grew at 49% from the fiscal year ended March 31, 2016 to the fiscal year ended March 31, 2017, and 40% from the fiscal year ended March 31, 2015 to the fiscal year ended March 31, 2016, and 47% from the fiscal year ended March 31, 2014 to the fiscal year ended March 31, 2015.2016. We view this as our most significant growth market. Since founding our U.S. business in 2008, we have established a successful direct sales, channel and service infrastructure to exploit this opportunity. We have also established a presence in Australia and expect expansion in that geography as our data centers there are now operational. We plan to investigate additional international expansion from our regional bases in the United States (for North America), the United Kingdom (for Europe), South Africa (for Africa and the Middle East) and Australia (for Asia-Pacific).

Target Organizations Moving Workloads to the Cloud. Given the compelling cost benefits and improved agility of cloud-based solutions, organizations are increasingly moving critical workloads to the cloud. As these IT workloads move to the cloud, we believe we are well-positioned to take advantage of growth opportunities that exist from augmenting services, including Microsoft Office 365® and G-Suite from Google®.

Our Technology

We have developed a native cloud architecture, including our own proprietary SaaS operating system, Mime | OS™, and customer-facing services, to address the specific risks and functional limitations of business email and data. Our innovative cloud-based approach requires no on-premises or hosted appliances. We believe we are one of only a few cloud architects that have fully committed to native cloud development.

We have a proven record of performing successfully at considerable scale and addressing rapidly growing customer demands. We process approximately 210307 million emails per day with over 130190 billion under management. We archive approximately 1828 petabytes of customer data and add more than 200480 terabytes of customer data per month and customer employee queries of their Mimecast email archive have grown from approximately 700,0001,000,000 to over 1,000,0001,800,000 per week in just one year.

We are able to provision customer email flows and onboard massive amounts of email data from legacy archives rapidly and efficiently. This drives customer adoption and makes the cloud transition easier than our customers typically expect. Once a customer is live on our service, adding new products to their subscription only requires activating itactivation from within their single administration console. This can be done with as little as one click and the new service is available across their business.

Our Proprietary Native Cloud Architecture—Mime | OSOS™

We developed a proprietary operating system called Mime | OSOS™ for native cloud services. Mime | OSOS™ enables secure multi-tenancy and takes advantage of the cost and performance benefits of using industry-standard hardware and resource sharing specifically for the secure management of email and data. This enables us to provision efficiently and securely across our customer base, minimizing the impact of spare or over-provisioned processing and storage capacity, reducing the cost of providing our services.

Mime | OSOS™ utilizes a common code base to control the hardware, and the storage, indexing, processing, services, administrator and user interface layers of our cloud environment. It has been specifically designed to enable us to scale our storage, processing and services to meet large enterprise-level email and data demands, while retaining the cost and performance benefits of a native cloud environment.

Mime | OSOS™ also streamlines our customer application development and enables strong integration across our services. All of our customer applications or services, use Mime | OSOS™ to interact with our single data stores and processing technology, as well as interoperate effectively with each other.


As set forth below, Mime | OSOS™ is our proprietary operating system that controls the interface, services, processing, indexing and storage layers of Mimecast’s cloud architecture.

Continuous Development Methodology and Multi-Tenancy Advantage

As we enhance and expand our technology, we can update services centrally with little or no intervention required by the customer as everyone shares the same core operating and application software. Improvements, upgrades, new products or patches are applied once and are available immediately across our whole service to customers. It also means we have only one up-to-date version of our service to maintain and support as well as a single, common data store for all customers that simplifies management, support and product development.

Our services already process and manage large volumes of customer data and this is growing daily. Our commitment to continual improvement in Mime | OS,OS™, our customer applications and hardware infrastructure mean we are constantly strengthening the performance of our service as we scale. These improvements include faster archive search times and data ingestion, greater storage density, improved processing and extended security coverage. Each week, we roll out updates and enhancements centrally that benefit our customers without the need for additional infrastructure investment on their part. Additionally, when new threats emerge, we act once by making changes to our service and all customers benefit immediately. We can also identify and act on threats to one customer and quickly prevent them from impacting others by changing our core system.

How Our Services Work

Mimecast EmailAdvanced Security

We protect inbound and outbound email from malware, spam, advanced persistent threats, email DoS and DDoS, data leaks and other security threats.

Inbound email is directed through Mimecast Email Security, which performs comprehensive security checks before the email is delivered to the customer’s infrastructure,e.g. Exchange,Microsoft Exchange®, Microsoft Office 365365® or Google. This prevents unwanted email from even reaching the customer in the first place and cluttering their infrastructure unlike on-premises services from competitors. Each day, we monitor approximately 460700 million messages delivering, on average, less than 50% to the customer.


Outbound email sent from the customer also passes through usour service and is checked before being sent on to prevent it from presenting a security threat to the recipient. Outbound email can also be encrypted, and scanned by our comprehensive content controls to prevent confidential documents or data leaving the business. Data leak prevention is a key consideration for all organizations.

Mimecast MailboxBusiness Continuity

Email is a 24x7 tool and, traditionally, customers who want to ensure their email does not experience downtime as a result of an inevitable outage or maintenance have had to replicate their own infrastructure in a second location, doubling their email-related costs. The cost and management burden of doing this is prohibitive for many, particularly small or mid-market organizations.

We are a cost effective alternative as there is no need for additional infrastructure. As all customer outbound and inbound email is coming through us anyway, when the customer’s primary email service fails, our Mimecast Mailbox Continuity service takes over the delivery and sending of email in real time or at the request of the administrator, offering immediate fail-over and fail-back. When the primary service is re-established, the customer is reassured that there has been no loss of data and that the archive is maintained. For employees the process is virtually invisible—they continue to work as before in their Microsoft OutlookOutlook® desktop email client, their Mimecast mobile app or their MacMac® Desktop App.

Mimecast Enterprise Information Archiving

Email, and the data it contains, needs to be safely archived to meet growing compliance, regulatory and legal obligations. Also, employees are increasingly using their email archive as their primary information store so this is further reason to ensure it is protected and archived effectively.

As email, file attachments, and associated critical metadata that identifies activity is sent or received, it can be saved in a secure, tamper-proof archive in the single Mimecast cloud automatically and indefinitely. Our employee mobile and desktop search tools, and administration console, then allow for detailed investigation of the archive. We also enable customers with legacy archive data to put this into their single Mimecast archive, which improves adherence to data compliance obligations and gives employees access to a complete historical view of their archive.

Our Mimecast Enterprise Information Archiving service offers secure lifetime storage of email, files and instant messaging conversations paid for on a per-employee not data usage basis. Expensive and ineffective onsite archives can be decommissioned, reducing the data load on the primary email service too. Our search tools make it easy for legal staff and employees themselves to quickly find data without the need to turn to the IT team. Finally, our archive can also include legacy data that would otherwise be held in additional storage. This can be ingested over-the-wire or via physical drives sent encrypted from the customer to us.

Our Global Data Center Network

We have built a network of ten data centers in five locations around the world to deliver our services. This gives customers geographic and jurisdictional control over data location, which enables them to address data privacy concerns. Each region operates two identical data centers that function in active-active mode in different locations, and have N+1 set-ups to meet our continuity of service commitments. Because of this redundancy, we are able to switch operations from one data center to another to maintain our customers’ email and data services. We have developed a modular approach to provisioning a new data center and can transition amongstamong data centers as needed in existing or new geographies.


Mimecast’sOur ten co-located data centers which are illustrated below, are replicated and operate in active-active mode to allow for continuity of service in the event of downtime or maintenance.

Email security isprovides a critical defense against hackers seeking to capture and exploit valuable corporateorganizational information and disrupt business operations. Our Mimecast Email Security service providesservices provide comprehensive email security. It preventsblocks spam, viruses, advanced threats, bulk mailmalware, malicious URLs, spear-phishing, and defined content from reaching inboxes, and protectsentering or exiting the security and integrity of outbound email communications.organization, It gives administrators granular security and content policy control for all inbound,  outbound, and with additional services, outboundinternal email traffic to prevent risksthreats, including data leaks. Integration into Microsoft Outlook and via mobile apps provides employees the freedom to be self-sufficient and have the ability to manage their quarantines.quarantines, personal blacklists, and multiple other aspects of their email security and management.


Customers can also benefit from the purchase of the following Mimecast security services:

Targeted Threat Protection: Highly sophisticated targeted attacks, including spear-phishing, are using email to successfully infiltrate organizations, exploit users and steal valuable intellectual property, customer data and money.

URL Protect addresses the threat from emails containing malicious links. It automatically checks hyperlinks each time they are clicked, preventing employees from visiting malicious websites regardless of what email client or device they are using. It also includes innovative user awareness capabilities so IT teams can raise the security awareness of employees as part of their daily email activities. Once enabled, a percentage of links in emails clicked by an employee will open an informational screen. This will provide them with more information about the email and destination, encouraging them to consider whether the email is coming from a reliable source and if the page is safe. If they choose to continue, the choice is logged and URL Protect scans the link and blocks access if the destination is deemed unsafe. IT administrators can adjust the frequency of these awareness prompts to ensure employee caution is maintained. Repeat offenders that regularly click bad links can automatically receive more frequent prompts until their behavior changes. The IT team can track employee behavior from the Mimecast administration console and target additional security training as required.

Attachment Protect reduces the threat from weaponized or malware-laden attachments used in spear-phishing and other advanced attacks. It includes pre-emptive sandboxing to automatically security check email attachments before they are delivered to employees. Attachments are opened in a virtual environment, or sandbox, isolated from the email system, security checked and passed on to the employee only if no threat is detected. It also includes the option of an innovative safe file conversion capability that automatically converts attachments into a safe file format, neutralizing any chance of malware as it does so. The attachment is delivered to the employee in read-only format without any sandbox analysis delay. As most attachments are read rather than edited, this is often sufficient for many users. Should the employee need to edit the attachment, they can request it and from there it is sandboxed on-demand and delivered in the original file format.

Impersonation Protect is the first to market service that gives instant and comprehensive protection from the latest malware-less social engineering attacks, often called CEO fraud, whaling, impersonation, or business email compromise. These attacks are designed to trick key users, often in an organization’s finance team, into making wire transfers or other financial transactions to cybercriminals by pretending to be the CEO or CFO via spoofed email. Some impersonation attacks also target those responsible for managing sensitive employee data, such as payroll information, which could be used for identity theft. Impersonation Protect detects and prevents these types of attack by identifying combinations of key indicators in an email to determine if the content is likely to be suspicious, even in the absence of a URL or attachment. Impersonation Protect blocks or flags suspicious email by using advanced scanning techniques to identify elements commonly used by criminals, including employee, domain, or reply-to names, and other keywords like ‘wire transfer,’ ‘tax form’ or ‘urgent.’

Internal Email Protect, or IEP, is the industry’s first threat management capability for internally generated email delivered by a purely cloud-based security service. IEP is the latest capability of Mimecast Targeted Threat Protection, allowing customers to monitor, detect and remediate security threats that originate from within their internal email systems. This first-to-market cloud capability provides for the scanning of attachments, URLs, and content in internally generated email. In addition, IEP includes the ability to automatically remediate infected email from a user’s inbox.

Secure Messaging: Email containing sensitive or confidential information requires appropriate security and control to prevent inadvertent or deliberate data leaks and to protect the information while in transit. Mimecast Secure Messaging is a secure and private channel to share sensitive information with external contacts via email without the need for additional client or desktop software. Sensitive information is kept within the Mimecast cloud service, strengthening information security, data governance and compliance, without the added IT overhead and complexity of traditional email secure messaging or encryption solutions.

Large File Send: Employees can create security and compliance risks when they turn to file sharing services to overcome email size limits imposed by their email infrastructure. Mimecast Large File Send enables PC and Mac users to send and receive large files directly from Outlook or a native Mac app. It protects attachments in line with security and content policies by using encryption, optional access key and custom expiration dates; supports audit, e-discovery and compliance by archiving all files and notifications according to email retention policies; and protects email system performance from the burden of large file traffic.

 

Targeted Threat Protection: Highly sophisticated targeted attacks, including spear-phishing, are using email to successfully infiltrate organizations, exploit users and steal valuable IP, customer data and money. Mimecast Targeted Threat Protection extends traditional gateway security to protect organizations against these advanced and highly targeted attacks. Also a threat dashboard and notification system provides real-time data, including audit and reporting, and enables administrators and security specialists to monitor and report attempted attacks. We launched Targeted Threat Protection URL Protect in April 2014, Attachment Protect in July 2015, and Impersonation Protect in March 2016.

URL Protect tackles the threat from emails containing malicious links. It automatically checks links each time they are clicked, preventing employees from visiting compromised websites regardless of what email client or device they are using. It also includes innovative user awareness capabilities so IT teams can raise the security awareness of employees. Once enabled, a percentage of links in emails clicked by an employee will open a warning screen. This will provide them more information about the email and destination, prompting them to consider whether the page is safe. If they choose to continue, the choice is logged and URL Protect scans the link and blocks access if the destination is unsafe. IT administrators can adjust the frequency of these awareness prompts to ensure employee caution is maintained. Repeat offenders that click bad links will automatically receive more frequent prompts until their behavior changes. The IT team can track employee behavior from the Mimecast administration console and target additional security training as required.

Attachment Protect reduces the threat from weaponized or malware-laden attachments used in spear-phishing and other advanced attacks. It includes pre-emptive sandboxing to automatically security check email attachments before they are delivered to employees. Attachments are opened in a virtual environment or sandbox, isolated from the corporate email system, security checked and passed on to the employee only if no threat is detected. It also includes the option of an innovative transcription service that automatically converts attachments into a safe file format, neutralizing malware as it does so. The attachment is delivered to the employee in read-only format without any delay. As most attachments are read rather than edited, this is often sufficient. Should the employee need to edit the attachment, they can request it is sandboxed on-demand and delivered in the original file format.

Impersonation Protectis the first to market service that gives instant and comprehensive protection from the latest malware-less social engineering attacks, often called CEO fraud, whaling or business email compromise. These attacks are designed to trick key users, often in an organization’s finance team, into making wire transfers or other financial transactions to cyber-criminals by pretending to be the CEO or CFO in a spoofed email. Some also target those responsible for sensitive employee data, such as payroll information, which could be used for identity theft. Impersonation Protect detects and prevents these types of attack by identifying

combinations of key indicators in an email to determine if the content is likely to be suspicious, even in the absence of a URL or attachment. Impersonation Protect blocks suspicious email by using advanced scanning techniques to identify elements commonly used by criminals, including employee and domain names, and other keywords like ‘wire transfer,’ ‘tax form’ or ‘urgent.’

Secure Messaging: Email containing sensitive or confidential information requires appropriate security and control to prevent inadvertent or deliberate data leaks and to protect its information while in transit. Mimecast Secure Messaging is a secure and private channel to share sensitive information with external contacts via email without the need for additional client or desktop software. Sensitive information is retained within the Mimecast cloud service strengthening information security, data governance and compliance, without the added IT overhead and complexity of traditional email encryption solutions. We launched Secure Messaging in April 2015.

Large File Send: Employees can create security and compliance risks when they turn to large file sharing tools to overcome email size limits imposed by their IT team or email infrastructure. Mimecast Large File Send enables PC and Mac users to send and receive large files directly from Outlook or a native Mac app. It protects attachments in line with security and content policies by utilizing encryption, optional access key and custom expiration dates; supports audit, e-discovery and compliance by archiving all files and notifications according to email retention policies; and protects email system performance from the burden of large file traffic. We launched Large File Send in July 2013.

Data Leak Prevention: CustomersPrevention: Organizations can prevent the inadvertent or malicious loss of sensitive corporate data with advanced data leak prevention and content controls. Policies using keywords, pattern matching, file hashes and


dictionaries actively scan all email communications including file attachments to stop data leakage and support compliance. Suspect emails can be blocked, quarantined for review by administrators or sent securely.

Mimecast MailboxBusiness Continuity

Email continuity protects email and data against the threat of downtime as a result of system failure, natural disasters, and the impact of planned maintenance, system upgrades and migrations. Mimecast Mailbox Continuity services significantly reduce the cost and complexity of mitigating these risks and provides uninterrupted access to live and historic email and calendar information. During an outage our service provides real-time inbound, outbound and internal email support.delivery. The continuity service can be activated and deactivated directly and instantly from our administrationthe Mimecast console by administrators for the complete organization or for specific groups affected by limited outages. All outage events are fully logged and we also support email top-up services for customers who have to recover their Exchange environments from backups. The continuity service is capable of reliably and securely supporting customers during short or long-term continuity events. Integration with Microsoft Outlook,Outlook®, a native app for MacMac® users and a full suite of mobile apps means employees have seamless access to their email in the event of ana disruption or outage.

Mimecast Enterprise Information Archiving

Our cloud archive consolidates into one store all inbound, outbound and internal email, files and instant messaging in a perpetual, indexed and secure archive. Using our Mimecast Enterprise Information Archiving service, customers can also incorporate legacy data from additional archives into the same searchable store.

All data is encrypted and preserved within a Write Once Read Many (WORM) state. Proprietary indexing and retrieval solutions allow customers to search individual mailboxes or the entire corporate archive in seconds. Our mobile, tablet, desktop and web applications ensure that employees can search and make the best use of their entire corporate archive in a fast, reliable and informative way. Intensive logging services cover the use of the archive, and roles and permissions govern what employees can see in the archive based on their role. Our purpose-built ingestion and export services support rapid high-volume extraction, scrubbing and loading of

significant quantities of data. Our archive solution retains metadata that arises from gateway and continuity operations and we preserve both received and altered variants of emails that pass through our secure email gateway.

Sales and Marketing

Our sales and marketing teams work together to build a strong sales pipeline, cultivate and retain customers and drive market awareness of our current and future products and services.

Sales

We sell our services through direct sales efforts and through our channel partners. Our sales model is designed to meet the needs of small and mid-market organizations and large enterprises across a wide range of industries and in over 100 countries. Our approach has played an important role in the growth of our customer base to date. Our sales team is based in offices in Boston, Chicago, Dallas and San Francisco, United States; London, United Kingdom; Johannesburg and Cape Town, South Africa; and Melbourne and Sydney, Australia. We maintain a highly-trained sales force of approximately 200300 employees as of March 31, 2016,2017, which is responsible for acquiring and developing new business.


We also have an experienced sales team focused on developing and strengthening our channel partner relationships. Many organizations work with third-party IT channel partners to meet their security, IT and cloud service needs, so we have formed relationships with a variety of the leading partners to target large enterprises, mid-market and small organizations. For large enterprises, we work with international partners including Avanade, Hewlett-Packard and Dimension Data. In the mid-market, we work with leading national partners, including Softchoice, SHI, CDW and Softcat. The small business market is primarily served by the reseller community and also by Managed Service Providers, who typically provide or host email services. We work closely with all of these channel partners to offer cooperative marketing, deal registration, as well as support and technical resources. We believe these partners view our services as a key source of additional revenue and a way for them to add significant value to their customers as they can support their desire to move to the cloud without compromising their security position.

Sales to our channel partners are generally subject to our standard, non-exclusive channel partner agreement, meaning our channel partners may offer customers the products of several different companies. These agreements are generally for a term of one year with a one year renewal term and can be terminated by us or the channel partner. Payment to us from the channel partner is typically due within 30 calendar days of the date we issue an invoice for such sales.

Our sales cycle varies by size and sophistication of customer, the number of products purchased and the complexity of the project, ranging from several days for incremental sales to existing customers, to many months for sales to new customers or large deployments.

We plan to continue to invest in our sales organization to support both the growth of our direct sales organization and our channel partners.

Marketing

Our marketing strategy is designed to meet the specific needs of each of our customer segments. We are focused on building ourthe Mimecast brand, and product awareness, increasing customer adoption of our products, communicating the advantages of our solution and its benefit to organizations, and generating leads for our channel partners and direct sales force. We execute our marketing strategy by using a combination of internal marketing professionals and a network of global channel partners. We invest in field, channel, product and brand marketing and have increased our investment in digital marketing to drive greater lead generation volume and efficiency. Our local marketing teams support the conversion of these leads into qualified opportunities for inside sales and are responsible for branding, content generation and product marketing.

Customer Service and Support

We maintain our strong customer retention rate through the strength and quality of our products, our commitment to our customers’ success and our award-winning local customer service and support team, which consists of more than 180200 employees worldwide dedicated to ensuring a superior experience for our customers. For each of the fiscal years ended March 31, 2017, 2016 2015 and 2014,2015, our customer renewal rate has been consistently greater than 90%. We calculate our annual customer retention rate as the percentage of paying customers on the last day of the prior year who remain paying customers ofon the last day of the current year.

We have designed a comprehensive monitoring methodology that tracks and evaluates the interactions we have with our customers from sales and on-boarding to support and renewal. Our cross-functional teams, under the supervision of our Chief of Customer Operations, work together to ensure the best customer experience is achieved and to address customer needs as they arise.

A key aspect of our customer on-boarding process is our Legacy Data Migration services. Our customers often have legacy email archives that they want to move to the cloud. Our data migration service helps solve the problems customers face when extracting that data and getting it into the right format for importing to the cloud, which can be expensive, time-consuming and involve interactions with multiple vendors.

In addition, we offer a full range of support services to our global customer base, including comprehensive online resources and 24x7 email support with no outsourcing of support or account management to third parties. We also offer a range of additional services that include options for 24x7 telephone support and a dedicated technical account manager. These support services are priced and tiered to meet specific customer requirements.

We also have a dedicated training team and resources designed to enable customers to get the full benefit from their Mimecast investment. Our comprehensive education and consultancy resources include administrator training and certification, end user training and e-discovery training for compliance teams, all of which are available in-person and online.


Beyond customer support and training, we also provide a range of services that are designed to provide additional support to some customers, especially larger enterprises with more complex email infrastructure and legacy data. Our professional services team works with the customer, or supports our partners to assist them, in planning, migration and service activation.

We also offer a standard service level agreement as part of our standard contract that contains commitments regarding the delivery of email messages to and from our servers, the speed at which our archive can produce search results, and our ability to correctly identify and isolate spam and viruses. In the event that we do not

achieve these levels, the customer can request a credit. Payment of the credit will be made subject to verification of the problem. These credits are tiered according to the extent of the service issued. The amount of credits provided to customers to date has been immaterial in all historical periods.

Customers

As of March 31, 2016,2017, we had approximately 18,00026,400 customers and protected millions of their employees in over 100 countries. Our diverse global footprint is evidenced by the fact that in the fiscal year ended March 31, 2016,2017, we generated 39%49% of our revenue from the United Kingdom, 43%States, 33% from the United States, 16%Kingdom, 15% from South Africa and 2%4% from the rest of the world. Our customers range from large enterprises with over 7,50075,000 employees to small organizations with less than 500 employees and represent a diverse set of industries. For example, in the fiscal year ended March 31, 2016,2017, we generated 16%14% of our revenue from customers in the legal services industry, 15%18% from customers in the professional, scientific and technical services industry, 13%10% from customers in the manufacturing industry and 12%13% from customers in the finance and insurance industry. Our business is not dependent on any particular customer. No single customer represented more than 1% of our annual revenues in the fiscal years ended March 31, 2017, 2016 2015 or 2014.2015.

Research and Development

Our engineering, operations, product and development teams work together to enhance our existing products, technology infrastructure and underlying Mime | OSOS™ cloud architecture, as well as develop our new product pipeline. Our research and development team interacts with our customers and partners to address emerging market needs, counter developing threats and drive innovation in risk management and data protection. We operate a continuous delivery model for improvements to our infrastructure and products to ensure customers benefit from regular updates in protection and functionality without the need for significant intervention on their part.

Our research and development efforts give prominence to services that enhance our unification commitment and allow customers to displace point or on-premises products. We also prioritize a “build rather than acquire” approach to ensure that we combine best-of-breed functionality with effective integration to maintain our commitment to the delivery of a superior experience to our customers and their employees.

Our research and development expenses were $22.6 million, $17.7 million $14.5 million and $12.8$14.5 million for the fiscal years ended March 31, 2017, 2016 2015 and 2014,2015, respectively.

Competition

Our market is large, highly competitive, fragmented, and subject to rapidly evolving technology and security threats, shifting customer needs and frequent introductions of new products and services. We do not believe that any specific competitor offers the fully unified service and integrated technology that we do. However, we do compete with companies that offer products that target email and data security, continuity and archiving, as well as large providers such as Google Inc. and Microsoft Corporation, who offer functions and tools as part of their core mailbox services that may be, or be perceived to be, similar to ours.our offerings. Our current and potential future competitors include: Barracuda Networks, Inc., Google, Microsoft Exchange Server, Exchange Online Protection, Proofpoint, Inc. and, Symantec Corporation and Cisco Systems Inc., in security, MessageOne, in continuity,and Hewlett Packard Enterprise, Microsoft Office 365®, Symantec and Barracuda HP Autonomy, Microsoft Office 365, Proofpoint and Symantec in archiving. Some of our current and future competitors may have certain competitive advantages such as greater name recognition, longer operating history, larger market share, larger existing user base and greater financial, technical and other resources. Some competitors may be able to devote greater resources to the development, promotion and sale of their products than we can to ours, which could allow them to respond more quickly than we can to new technologies and changes in customer needs. We cannot provide any assurance that our competitors will not offer or develop products or services that are superior to ours or achieve greater market acceptance.


The principal competitive factors in our market include:

reliability and effectiveness in protecting, detecting and responding to cyber-attacks;cyberattacks;

scalability and multi-tenancy of our system;

breadth and unification of our services;

cloud-only delivery;

total cost of ownership;

speed, availability and reliability;

integration into office productivity, desktop and mobile tools;

speed at which our services can be deployed;

ease of user experience for IT administrators and employees; and

superior customer service and commitment to customer success.

We believe that we compete favorably on the basis of these factors. Our ability to remain competitive will depend to a great extent upon our ongoing performance in the areas of product and cloud architecture development, core technical innovation, channel management and customer support.

Intellectual Property

Our success is dependent, in part, on our ability to protect our proprietary technologies and other intellectual property rights. We primarily rely on a combination of trade secrets, copyrights and trademarks, as well as contractual protections to establish and protect our intellectual property rights. As of March 31, 2016,2017, we had threehave 8 patents issued and 1114 patent applications pending in the United States. We also have one patent4 patents issued and five5 patent applications pending for examination in non-U.S. jurisdictions, and four pending Patent Cooperation Treaty patent applications, all of which are counterparts of our U.S. applications.jurisdictions. We intend to pursue additional patent protection to the extent that we believe it would be beneficial and cost effective.

We have registered “Mimecast” and certain other marks as trademarks in the United States and several other jurisdictions. We also have a number of registered and unregistered trademarks in the United States and certain other jurisdictions, and will pursue additional trademark registrations to the extent we believe it would be beneficial and cost effective. We are the registered holder of a variety of domestic and international domain names that include “mimecast.com,” “mimecast.co.uk,” “mimecast.co.za,” and similar variations.

In addition to the protection provided by our intellectual property rights, as part of our confidentiality procedures, all of our employees and independent contractors are required to sign agreements acknowledging that all inventions, trade secrets, works of authorship, developments and other processes generated by them on our behalf are our property, and they assign to us any ownership that they may claim in those works. We also generally enter into confidentiality agreements with our employees, consultants, partners, vendors and customers, and generally limit access to and distribution of our proprietary information.

Despite our precautions, it may be possible for unauthorized third parties to copy our products and use information that we regard as proprietary to create products and services that compete with ours.

Some license provisions protecting against unauthorized use, copying, transfer and disclosures of our products may be unenforceable under the laws of certain jurisdictions and foreign countries. In addition, the laws of some countries do not protect proprietary rights to as great of an extent as the laws of the United States, and many foreign countries do not enforce these laws as diligently as government agencies and private parties in the

United States. Our exposure to unauthorized copying and use of our products and misappropriation of our proprietary information may increase as a result of our foreign operations.

We expect that software and other solutions in our industry may be increasingly subject to third-party infringement claims as the number of competitors grows and the functionality of products in different industry segments overlap. Moreover, many of our competitors and other industry participants have been issued patents or filed patent applications, and have asserted claims and related litigation regarding patent and other intellectual property rights. Third parties, including non-practicing patent holders, have from time to time claimed, and could claim in the future, that our technologies infringe patents they now hold or might obtain or be issued in the future. See “Item 3. Key Information—D. Risk Factors—We may be sued by third parties for alleged infringement of their proprietary rights”.


C. OrganizationalOrganizational Structure

Mimecast Limited has seveneight subsidiaries. Our principal operating companies are Mimecast Limited, a UK company, Mimecast Services Ltd, a UK company, and Mimecast North America Inc., a Delaware corporation, each of which is a wholly-owned subsidiary of Mimecast Limited.

D. Property, Plant, and Equipment

Our corporate headquarters is located in London, United Kingdom where we currently lease approximately 40,993 square feet of space under a lease expiring in December 2019. In April 2017, we signed a lease for an additional approximately 16,100 square feet of space contiguous with our existing space in London, which lease will also expire in December 2019. Our U.S. headquarters is located in Watertown, Massachusetts in an office consisting of approximately 44,170 square feet of space under a lease expiring in October 2020. In February 2017, we entered into a lease for a new U.S. headquarters located in Lexington, Massachusetts. We expect to occupy the new facility, which will initially encompass approximately 79,145 square feet of space, in or around December 2017.  The lease for the new U.S. headquarters will expire 10 years after initial occupancy.  We also occupy space in Johannesburg, South Africa consisting of 22,722 square feet under a lease expiring in October 2016.2018. We also maintain additional leased facilities in Cape Town, South Africa, Melbourne and Sydney, Australia, as well as in Chicago, Dallas and San Francisco in the United States.

We lease all of our facilities and do not own any real property. We intend to procure additional space as we add employees and expand geographically. We believe that our facilities are adequate for our current needs and that suitable additional or substitute space will be available as needed to accommodate planned expansion of our operations.

E. Section 219 Disclosure

Section 219 of the Iran Threat Reduction and Syria Human Rights Act of 2010 added Section 13(r) to the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Section 13(r) requires an issuer to disclose in its annual or quarterly reports, as applicable, whether it or any of its affiliates knowingly engaged in certain activities, transactions, or dealings relating to Iran or with designated natural persons or entities involved in terrorism or the proliferation of weapons of mass destruction during the period covered by the report. Disclosure is required even when the activities, transactions or dealings are conducted outside of the United States bynon-U.S. affiliates in compliance with applicable law, and whether or not the activities are subject to sanctions under U.S. law.

As of the date of this report, the Company is unaware of any activity, transaction, or dealings by us or any of our affiliates during the period ended March 31, 2016, that requires disclosure in this report under Section 13(r) of the Exchange Act, except as set forth below.

In October 2008, an order was placed by a third-party U.K. reseller of Mimecast Services Ltd. (“MSL”), our U.K. operating company, for ongoing email archiving services to be provided to Persia International Bank PLC (“PIB”), which is based in London, United Kingdom. The services included cloud-hosted email security, archiving, and continuity management. MSL fulfilled the order and it was automatically renewed in November 2009, December 2010, December 2011, December 2012, December 2013, and December 2014.

We do not believe that these transactions by the U.K. operating subsidiary of what was then a U.K. parent company were subject to regulation under U.S. sanctions against Iran. But MSL’s provision of services to PIB after July 26, 2010 may have breached EU Council Regulation 267/2012, pursuant to which PIB was named as a designated person on the EU Council Regulation against Iran. The Company terminated the PIB account with the U.K. reseller and stopped processing email for PIB on or about April 24, 2015. On January 16, 2016, the EU lifted the sanctions on PIB and its shareholder banks, Bank Mellat and Bank Tejarat.

From the third-party U.K. reseller and related to the PIB account, MSL collected £2,545.64 in 2009; £2,093.00 in 2010; £2,138.50 in 2011; £2,002.00 in 2012; £2,183.97 in 2013; and £1,455.97 in 2014. On June 10, 2015, MSL credited £575.35 back to the third-party U.K. reseller relating to the balance of the December 2014 invoice for cancelled services. That same day, MSL also wrote off bad debt of £1,608.62 for all outstanding invoice amounts relating to unpaid PIB receivables as of March 31, 2015. MSL has not received payment from the third-party reseller related to this account since August 2014.

The below table shows the calendar year, amount invoiced, amount collected, amount credited, amount written off, and remaining balance (all inclusive of VAT taxes):

The gross revenue inclusive of VAT tax (i.e., the sum of all payments, including VAT taxes, collected from the third-party U.K. reseller and related to the PIB account) is thus £12,419.08. VAT taxes accounted for £1,910.96 of the £12,419.08; considering this and the credit of £575.35, net revenue is thus £9,932.77. Using the Company’s average Net Profit rate of 0.25% of net revenue, the Company believes that its net profit related to the PIB account is approximately £24.83 during the life of the relationship.

Since terminating the PIB account in April, 2015, the Company has implemented additional export control compliance management oversight and has undertaken remedial measures to reduce the risk of similar events occurring in the future.

We operate our business on a SaaS model with renewable annual subscriptions. Customers enter into annual and multi-year contracts to utilize various components of our services. Our subscription fee includes the use of the selected service and technical support. We believe our technology, subscription-based model, and customer support have led to our high revenue retention rate, which has helped us drive our strong revenue growth. We have historically experienced significant revenue growth from our existing customer base as they renew our services and purchase additional products.

We market and sell our services to organizations of all sizes across a broad range of industries. As of March 31, 2016,2017, we provided our services to approximately 18,00026,400 customers and protected millions of their employees across the world. We generate sales through our network of channel partners as well as through our direct sales force. Our growth and future success depends on our ability to expand our customer base and to sell additional services to our existing customers. The total number

In the fiscal year ended March 31, 2017, we generated 51% of our customers increased by 30%revenue outside of the United States, with 33% generated from March 31, 2015 to March 31, 2016.

the United Kingdom, 15% from South Africa and 3% from the rest of the world. In the fiscal year ended March 31, 2016, we


generated 57% of our revenue outside of the United States, with 39% generated from the United Kingdom, 16% from South Africa and 2% from the rest of the world. In the fiscal year ended March 31, 2015, we generated 62% of our revenue outside of the United States, with 42% generated from the United Kingdom, 19% from South Africa and 2% from the rest of the world. Our most significant growth market is the United States. We also believe that there is significant opportunity in our other existing markets. We intend to make significant investments in sales and marketing to continue expanding our customer base in our target markets.

The majority of our revenue is generated from annual subscriptions. Our services are implemented, configured and operated without the need for substantial training or professional services. For customers that choose to develop increased proficiency in our service or who require assistance for more complex configurations and for those that wish to import historical data, we offer additional services.

We were founded in 2003 with a mission to make email safer and better, and to transform the way organizations protect, store and access their email and corporate information. Our first service, Mimecast Email Security, which we launched in late 2003 and was quickly followed by Mimecast Email Continuity. In 2004, we added Mimecast Enterprise Information Archiving. These three services generate a large proportion of our revenue today. In 2006, we started the development of our proprietary cloud architecture, which we refer to as Mime | OS™. We believed early on that investing in the development of our own cloud operating system was a strategic requirement that would enable us to integrate and scale our services. Mimecast Large File Send was released in 2013 and was followed by Mimecast Targeted Threat Protection in 2014, our advanced persistent threat protection service. In 2014, we also released comprehensive risk mitigation technologies specifically for Microsoft Office 365,365®, and in 2015, we released Mimecast Secure Messaging. In 2016 and 2017, we announced the newest aspectaspects of our Targeted Threat Protection service, Impersonation Protect.Protect and Internal Email Protect, respectively.

In November 2015, we completed our initial public offering, or IPO, in which we issued and sold 7,750,000 ordinary shares at a public offering price of $10.00 per share. We received net proceeds of $68.3 million after deducting underwriting discounts and commissions of $5.4 million and other offering expenses of $3.8 million.

In October 2016, we completed a registered secondary public offering, in which 4,600,000 ordinary shares were sold at a public offering price of $16.50 per share. All of the shares sold in the secondary offering were sold by our existing shareholders and we did not receive any proceeds from the sale of these shares. We have achieved significant revenue growth in recent periods. Our revenue grew 22% from $116.1incurred approximately $0.6 million in offering expenses on behalf of the year ended March 31, 2015selling shareholders in connection with the secondary offering.

In November 2016, we purchased substantially all of the assets of iSheriff, Inc., or iSheriff, a cloud-based security provider. This acquisition is intended to $141.8provide our customers additional real-time email threat intelligence and detection expertise and complements our existing portfolio of email security, continuity and archiving solutions. The total preliminary purchase price of $6.2 million consisted of a cash payment of approximately $5.6 million, subject to certain adjustments, and $0.6 million in purchase price held back in respect of claims for indemnification for one year from the year ended March 31, 2016. Revenue grew 31% from $88.3purchase date. We incurred approximately $0.7 million in transactional costs in connection with the year ended March 31, 2014 to $116.1 million in the year ended March 31, 2015.

We incurred a net loss of $3.2 million in the year ended March 31, 2016 and had net income of $0.3 million in the year ended March 31, 2015. We incurred a net loss of $16.9 million in the year ended March 31, 2014.

Service Disruption

On September 21, 2015, we experienced a service disruption that resulted in service downtime for many of our U.S. customers for several hours. As a result of the service disruption, we voluntarily provided service credits to affected customers in the year ended March 31, 2016, totaling approximately $0.4 million, all of which were paid as of March 31, 2016.transaction.  

Key Factors Affecting Our Performance

We believe that the growth of our business and our future success are dependent upon a number of key factors, including the following:

Acquisition of New Customersnew customers. We employ a sales strategy that focuses on acquiring new customers through our direct sales force and network of channel partners, and selling additional products to existing customers. Acquiring new customers is a key element of our continued success, growth opportunity and future revenue. We have invested in and intend to continue to invest in our direct sales force and channel partners. During the year ended March 31, 2016,2017, our customer base increased by approximately 4,2008,400 organizations.

Further Penetrationpenetration of Existing Customersexisting customers. Our direct sales force, together with our channel partners and dedicated customer experience team seek to generate additional revenue from our existing customers by adding more employees and selling additional services. We believe a significant opportunity exists for us to sell additional services to current customers as they experience the benefits of our services and we address additional business use cases.

Investment in Growthgrowth. We are expanding our operations, increasing our headcount and developing software to both enhance our current offerings and build new features. We expect our total operating expenses to increase, particularly as we continue to expand our sales operations, marketing activities and research and development team. We intend to continue to invest in our sales, marketing and customer experience organizations to drive additional revenue and support the growth of our customer base. Investments we make in our sales and marketing and research and development organizations will occur in advance of experiencing any benefits from such investments. For the year ending March 31, 2017,2018, we plan to continue increasing the size of our direct sales force and to invest in the development of additional marketing content. We also expecthave increased and plan to significantlycontinue to increase the size of our research and development team.


Currency Fluctuationsfluctuations. We conduct business in the United States and in other countries in North America, the United Kingdom and other countries in Europe, South Africa and other countries in Africa, and also Australia. As a result, we are exposed to risks associated with fluctuations in currency exchange rates, particularly between the U.S. dollar, the British pound and the South African rand. In the year ended March 31, 2016, 37%2017, 50% of our revenue was denominated in U.S. dollars, 31% in British pounds, 44% in U.S. dollars, 16%15% in South African rand and 3%4% in other currencies. Given that our functional currency and thatthe functional currency of our subsidiaries is the local currency of each entity but our reporting currency is the U.S. dollar, devaluations of the British pound, South African rand and other currencies relative to the U.S. dollar impacts our profitability.

Key Performance Indicators

In addition to traditional financial metrics, such as revenue and revenue growth trends, we monitor several other key performance indicators to help us evaluate growth trends, establish budgets, measure the effectiveness of our sales and marketing efforts and assess operational efficiencies. The key performance indicators that we monitor are as follows:

Rounded up

Reflects the customer count on the last day of the period rounded to the nearest hundred customers.

Gross Profit Percentageprofit percentage. Gross profit percentage is calculated as gross profit divided by revenue. Our gross profit percentage has remained relatively constant overincreased in each of the past three years. Gross profit fluctuates due to timing of the addition of hardware and employees to serve our growing customer base. We provide our services in each of the regions in which we operate. Costs related to supporting and hosting our product offerings and delivering our services are incurred in the region in which the related revenue is recognized. As a result, our gross profit percentage in actual terms is the same as it would beconsistent with gross profit on a constant currency basis.

Revenue Constant Currency Growth Rateconstant currency growth rate. We believe revenue constant currency growth rate is a key indicator of our operating results. We calculate revenue constant currency growth rate by translating revenue from entities reporting in foreign currencies into U.S. dollars using the comparable foreign currency exchange rates from the prior fiscal year.period. For further explanation of the uses and limitations of this measure and a reconciliation of our revenue constant currency growth rate to revenue, as reported, the most directly comparable GAAP measure, please see “Item 3—Key Information—A. Selected Consolidated Financial and Other Data.” As our total revenue grew over the past three years, ourOur revenue constant currency growth rate has declined slightly over the same period,increased in fiscal 2017 as compared to prior periods.  As our total revenue grows, we expect our constant currency growth rate will decline as the incremental growth from period to period representedis expected to represent a smaller percentage of total revenue as compared to the prior period.

Revenue Retention Rateretention rate. We believe that our ability to retain customers is an indicator of the stability of our revenue base and the long-term value of our customer relationships. Our revenue retention rate is driven by our customer renewals and upsells. For each of the fiscal years ended March 31, 2017, 2016 2015 and 2014,2015, our customer retention rate has been consistently greater than 90%. We calculate our revenue retention rate by annualizing constant currency revenue recorded on the last day of the measurement period for only those customers in place throughout the entire measurement period. We include add-on, or upsell, revenue from additional employees and services purchased by existing customers. We divide the result by revenue on a constant currency basis on the first day of the measurement period for all customers in place at the beginning of the measurement period. The measurement period is the trailing twelve months. The revenue on a constant currency basis is based on the average exchange rates in effect during the respective period. Our revenue retention rate has increased overin each of the past three years.

Total Customerscustomers. We believe the total number of customers is a key indicator of our financial success and future revenue potential. We define a customer as an entity with an active subscription contract as of the measurement date. A customer is typically a parent company or, in a few cases, a significant subsidiary that works with us directly. We expect to continue to grow our customer base through the addition of new customers in each of our markets.


Adjusted EBITDA. We believe that Adjusted EBITDA is a key indicator of our operating results. We define Adjusted EBITDA as net (loss) income, adjusted to exclude: depreciation and amortization, share-based compensation expense, restructuring expense, interest income and interest expense, the provision for income taxes and foreign currency exchange income (expense). For further explanation of the uses and limitations of this measure and a reconciliation of our Adjusted EBITDA to the most directly comparable GAAP measure, net (loss) income, please see “Item 3. —Key Information—A. Selected Consolidated Financial and Other Data.” We expect that our Adjusted EBITDA will decreasecontinue to increase; however, we expect that our operating expenses will also increase in the near termabsolute dollars as we focus on expanding our sales and marketing teams and growing our research and development capabilities as well as expand our sales and marketing teams.capabilities.

Components of Consolidated Statements of Operations

Revenue

We generate substantially all of our revenue from subscription fees paid by customers accessing our cloud services and by customers purchasing additional support beyond the standard support that is included in our basic subscription fees. A small portion of our revenue consists of related professional services and other revenue, which consists primarily of set-up fees, ingestion fees and training fees.

We generally license our services on a price per employee basis under annual contracts. Some services, such as ingestion services, are invoiced upfront and recognized on a straight-line basis over the longer of the contract term or the average customer life.

We serve thousands of customers in multiple industries, and our revenue is not concentrated with any single customer or industry. For each of the years ended March 31, 2017, 2016 2015 and 2014,2015, no single customer accounted for more than 1% of our revenue, and our largest ten customers accounted for less than 10% of our revenue in aggregate.

Amounts that have been invoiced are recorded in accounts receivable and in deferred revenue or revenue, depending on whether the revenue recognition criteria have been met. AtAs of March 31, 2016,2017, deferred revenue was $70.0$95.3 million. EstimatedWe estimate the future recognition fromof deferred revenue atas of March 31, 2016 was $60.9 million in 2017 $3.9to be $84.2 million in 2018, $2.8$5.2 million in 2019, $3.3 million in 2020, $1.9 million in 2021 and $2.4$0.7 million thereafter.

We have continued to expand our customer base, and have recently signed on more customers with monthly, instead of annual, billing terms. The proportion of aggregate contract value reflected on our balance sheet as deferred revenue may decrease if this trend continues.

We recognize revenue ratably on a straight-line basis over the subscription term, which is typically one year in duration, provided that an enforceable contract has been signed by both parties, we have given the customer access to our SaaS solutions, collection of the fee is probable, and the fee is fixed or determinable. Our subscription service arrangements do not contain refund-type provisions.

Our professional services contracts are on a time and material basis. When these services are not combined with subscription revenues as a single unit of accounting, as discussed in the section below entitled “—Critical Accounting Policies and Estimates,” these revenues are recognized as the services are rendered.

Cost of Revenuerevenue

Cost of revenue primarily consists of expenses related to supporting and hosting our product offerings and delivering our professional services. These costs includeconsist primarily of personnel and related costs including salaries, benefits, bonuses and share-based compensation expense related to the management of our data centers, our customer support team and our professional services team. In addition to these expenses, we incur third-party service provider costs such as data center and networking expenses, allocated overhead costs and depreciation expense. We allocate overhead costs,

such as rent and facility costs, information technology costs and employee benefit costs to all departments based on headcount. As such, general overhead expenses are reflected in cost of revenue and each operating expense category.

We currently expect our cost of revenue to increase in absolute dollars due to expenditures related to the purchase of hardware, expansion and support of our data center operations and customer support teams. We also expect that cost of revenue as a percentage of revenue will decrease over time as we are able to achieve economies of scale in our business, although it may fluctuate from period to period depending on the timing of significant expenditures. To the extent that our customer base grows, we intend to continue to invest additional resources in expanding the delivery capability of our products and other services. The timing of these additional expenses could affect our cost of revenue, both in terms of absolute dollars and as a percentage of revenue in any particular quarterly or annual period.


Research and Development Expensesdevelopment expenses

Research and development expenses consist primarily of personnel and related costs, including salaries, benefits, bonuses, share-based compensation expense, costs of server usage by our developers and allocated overhead costs. We expense all research and development costs as they are incurred. We have focused our efforts on developing new versions of our SaaS technology with expanded features. Our technology is constantly being refined and, as such, we do not capitalize development costs. We believe that continued investment in our technology is important for our future growth. As a result, we expect research and development expenses to increase in absolute dollars as we investmake further substantial investments in further developing our Mime | OSOS™ platform, improving our existing services and creating new features that will increase the functionality of our new and existing products. Research and development expenses as a percentage of total revenue may fluctuate on a quarterly basis but we expect it to increase in the near-term as a result of the substantial expected investments noted above.

Sales and Marketing Expensesmarketing expenses

Sales and marketing expenses consist primarily of personnel and related costs, including salaries, benefits, bonuses, commissions and share-based compensation.compensation expense. Other costs included are those relating to marketing and promotional events, online marketing, product marketing and allocated overhead costs. We expense all costs as they are incurred, including sales commissions.  Sales and marketing expenses increased substantially in fiscal 2017 as we continued to expand our sales and marketing efforts globally, particularly in the United States. We expect that our sales and marketing expenses will continue to increase substantially in the year ending March 31, 2017 as we expand our sales and marketing efforts globally, and particularly in the United States.2018. New sales personnel require training and may take several months or more to achieve productivity; as such, the costs we incur in connection with the hiring of new sales personnel in a given period are not typically offset by increased revenue in that period and may not result in new revenue if these sales personnel fail to become productive. We expect to increase our investment in sales and marketing as we add new services, which will increase these expenses in absolute dollars. Over the long term, we believe that sales and marketing expenses as a percentage of revenue will decrease, but will vary depending upon the mix of revenue from new and existing customers, as well as changes in the productivity of our sales and marketing programs.

General and Administrative Expensesadministrative expenses

General and administrative expenses consist primarily of personnel and related expenses for executive, legal, finance, information technology and human resources functions, including salaries, benefits, incentive compensation and share-based compensation expense, in addition to the costs associated with professional fees, insurance premiums, other corporate expenses and allocated overhead costs. In future periods, weWe expect general and administrative expenses to increase in absolute dollars as we continue to incur additional personnel and professional services costs in order to meetsupport business growth as well as meeting the compliance requirements of operating as a public company, including those costs incurred in connection with Section 404 of the Sarbanes-Oxley Act.Act, costs associated with the expected loss of our status as a foreign private issuer, and costs associated with the adoption of new accounting standards, including ASC 606, Revenue Recognition and ASU 2016-02, Leases, among others. Over the long term, we believe that general and administrative expenses as a percentage of revenue will decrease.

Restructuring

Restructuring consist of severance, outplacement, and other separation benefits.

Other Income (Expense)income (expense)

Other income (expense) is comprised of the following items:

Interest income

Interest income includes interest income earned on our cash, and cash equivalents balance.and investments balances. We expect interest income to vary each reporting period depending on our average cash, and cash equivalents balanceand investments balances during the period and market interest rates. We expect interest income to increase in the fiscal year ending March 31, 2018 due to higher yields on investments.

Interest expense

Interest expense consists primarily of interest expense associated with our credit facilityoutstanding debt and our outstanding debt.credit facility.


Foreign exchange income (expense)

Foreign exchange income (expense) consists primarily of foreign exchange fluctuations related to short-term intercompany accounts and foreign currency exchange gains and losses related to transactions denominated in currencies other than the functional currency for each of our subsidiaries. We expect our foreign currency exchange gains and losses to continue to fluctuate in the future as foreign currency exchange rates change.change, however, we expect foreign currency exchange gains and losses to be less significant in the fiscal year ending March 31, 2018 as compared to the fiscal year ended March 31, 2017 due to the capitalization and repayment of certain intercompany balances at the end of our second fiscal quarter of 2017.

Provision for Income Taxesincome taxes

We operate in several tax jurisdictions and are subject to taxes in each country or jurisdiction in which we conduct business. We account for income taxes in accordance with the asset and liability method. Under this method, deferred tax assets and liabilities are recognized based on temporary differences between the financial reporting and income tax bases offor assets and liabilities using statutory rates. In addition, this method requires a valuation allowance against net deferred tax assets if, based upon the available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized. To date, we have incurred cumulative net losses in all jurisdictions exceptOur provision for South Africa and maintain a full valuation allowance on our net deferred tax assets. Our tax expenseincome taxes for the fiscal years ended March 31, 2017, 2016 2015 and 20142015 primarily relates to our foreign subsidiaries, primarily our South African jurisdiction.

Revenue increased $44.7 million in the year ended March 31, 2017 compared to the year ended March 31, 2016. The increase in revenue was primarily attributable to increases in new customers, including the 8,400 new customers added since March 31, 2016, a full year of revenue related to new customers added in fiscal 2016 and additional revenue from customers that existed as of March 31, 2016. Revenue for the year ended March 31, 2017 compared to the year ended March 31, 2016 was negatively impacted by approximately $9.9 million primarily as a result of the strengthening of the U.S. dollar relative to the British pound and to a lesser extent the South African rand.

Cost of revenue increased $8.5 million in the year ended March 31, 2017 compared to the year ended March 31, 2016, which was primarily attributable to increases in data center costs of $3.9 million, personnel-related costs of $2.7 million, depreciation expense of $1.0 million and share-based compensation expense of $0.7 million. Cost of revenue for the year ended March 31, 2017 compared to the year ended March 31, 2016 was positively impacted by approximately $3.2 million primarily as a result of the strengthening of the U.S. dollar relative to the British pound. Data center costs increased as a result of the increase in our customer base, personnel-related cost increased primarily as a result of salaries and benefits associated with increased headcount, depreciation increased primarily as a result of increased capital expenditures in support of our expanding infrastructure and share-based compensation expense increased primarily as a result of an increase in share option modification charges.

As a result of changes in foreign exchange rates, gross profit decreased in absolute dollars by approximately $6.7 million for the year ended March 31, 2017 as compared to the year ended March 31, 2016. Excluding the impact of changes in foreign currency exchange rates, gross profit as a percentage of revenue remained consistent as costs related to supporting and hosting our product offerings and delivering our services are incurred in the region in which the related revenue is recognized.

Other income (expense) increased $6.9 million in the year ended March 31, 2017 compared to the year ended March 31, 2016, which was primarily attributable to a $6.1 million increase in foreign exchange income associated with the re-measurement of short-term intercompany balances as well as working capital balances denominated in currencies other than the functional currency of our operating units. The increase in foreign exchange income is a result of the British pound weakening compared to the foreign currencies in which we operate to a greater extent in fiscal 2017 as compared to fiscal 2016.  The increase in interest income is primarily due to higher weighted-average cash and investment balances after the IPO.  The decrease in interest expense is primarily due to a decrease in weighted-average debt balances.

Other income (expense) increased $9.4 million in 2015 compared to 2014 attributable primarily to changes in foreign exchange (expense) income. In the year ended March 31, 2014, we recognized foreign exchange expense, primarily attributable to the re-measurement of short-term intercompany asset and liability balances as a result of the U.S. dollar weakening compared to the British pound.

In the year ended March 31, 2015, we recognized foreign exchange income attributable primarily to the re-measurement of short-term intercompany asset and liability balances as a result of the U.S. dollar strengthening compared to the British pound. The increase in interest expense was attributable primarily to higher weighted-average principal outstanding in the year ended March 31, 2015 as compared to the year ended March 31, 2014.

Quarterly Results of Operations

The following tables set forth our unaudited quarterly consolidated statements of operations for each of the eight quarters in the period ended March 31, 2016.2017. We have prepared the quarterly consolidated statements of operations data on a basis consistent with the audited consolidated financial statements, including, in the opinion of management, all normal and recurring adjustments, which we consider necessary for a fair presentation of this data. This information should be read in conjunction with the audited consolidated financial statements and related notes included elsewhere in this Annual Report on Form 20-F. The results of historical periods are not necessarily indicative of the results to be expected for any future period.

In November 2015, we raised net proceeds of $68.3 million in our IPO, after deducting underwriting discounts and commissions and offering expenses paid by us. Prior to our IPO in November 2015, we financed our operations primarily through private placements of equity and borrowings from our primary bank lender. In November 2015, we raised net proceeds of $68.3 million

in our IPO, after deducting underwriting discounts and commissions and offering expenses payable by us. In the yearyears ended March 31, 2017 and 2016, we incurred operating losses were reducedof $10.4 million and we generated operating cash flows.$2.6 million, respectively. While we expect to generate an operating loss in the year ending March 31, 2017,2018, we expect to continue to generate positive cash flows from operating activities. In the year ending March 31, 2017,2018, we plan to continue to invest in the development and expansion of our Mime | OSOS™ platform to improve on our existing solutions in order to provide more capabilities to our customers. Investments in capital expenditures in the year ended March 31, 20162017 were $14.2$18.5 million. We expect this level of investment to increase in the year ending March 31, 2017.2018.

As of March 31, 20162017 and 2015,2016, we had cash, and cash equivalents and investments of $106.1$111.7 million and $32.9$106.1 million, respectively. Based on our current operating plan, we believe that our current cash and cash equivalents, investments and operating cash to be received from existing and new customersflows will be sufficient to fund our operations for at least the next twelve months. Our future capital requirements may vary materially from those planned and will depend on certain factors, such as, our growth and our operating results. If we require additional capital resources to grow our business or to acquire complementary technologies and businesses in the future, we may seek to sell additional equity or raise funds through debt financing or other sources. We may also seek to invest in or acquire complementary businesses, applications or technologies, any of which could also require us to seek additional equity or debt financing. We cannot provide assurance that additional financing will be available at all or on terms favorable to us. We had no material commitments for capital expenditures as of March 31, 20162017 or 2015.2016.


Borrowings and Credit Facilitycredit facility

Since January 2012, we have entered into various term loan borrowings with Silicon Valley Bank. The term loans have fixed interest rates of 4.5% and principal repayment periods of 36 equal monthly installments with variousremaining maturities through January 2018. As of March 31, 2016,2017, the aggregate principal balance of the term loans was $6.9$1.7 million, all of which $4.9 million is payable in the year ending March 31, 2017.2018. As of March 31, 20162017 and 2015,2016, there were no amounts available for future borrowings under the term loans.

In January 2013, we entered into a loan and security agreement with Silicon Valley Bank providing for a revolving credit facility. In July 2014, we amended and restated that agreement to increase the borrowing capacity under the facility from £7.5 million to £10.0 million (or, in each case, the equivalent amount in either U.S. dollars or Euros). This facility has £5.0 million in immediately available credit and another £5.0 million upon completion of an additional equity financing, which occurred upon completion of our IPO. The revolving credit facility bears interest at the greater of (i) the Bank of England base rate plus 3.5% or (ii) 4.0% and has aexpired unused in July 2016.  Our term of 24 months. As of March 31, 2016 and 2015, the effective rate on the line of credit was 4.0%. The line of credit isloan borrowings are collateralized by substantially all of our assets and we are required to meet certain financial covenants, including recurring revenue and adjusted quick ratio covenants. The agreement also contains the following negative covenants:

a commitment not to pay dividends or make distributions or payments or to redeem, retire or repurchase our share capital; and

negative pledges by us and our subsidiaries, including with respect to:

limitations on dissolution, any subordinated debt arrangement, mergers, acquisitions, investments, dispositions and transactions with affiliates not in the ordinary course of business;

limitations on assigning, mortgaging, pledging, granting a security interest or encumbering any of our property (other than permitted liens identified in the agreement); and

restrictions on changes in business, management, ownership, business locations or organizational structure.

Failure to meet these financial and other covenants would enable the bankSilicon Valley Bank to demand immediate repayment of all outstanding balances under the facility.loan agreement. We were in compliance with the terms of the credit facilityall covenants as of

March 31, 2016 and 2015. On November 13, 2015, we amended the loan and security agreement to reflect the change in reporting entity due to our redomiciliation from a U.K. company to a Jersey company in connection with our IPO, to make available the additional £5.0 million in available credit under the facility that became accessible upon the completion of the IPO, and to adjust certain financial covenants, including recurring revenue and adjusted quick ratio covenants. As of March 31, 20162017 and 2015, there was no balance outstanding under2016.

Operating activities

For the line of credit. As ofyear ended March 31, 2016, £10.02017, cash provided by operating activities was $32.5 million. The primary factors affecting our operating cash flows during the period were our net loss of $5.4 million, was availableadjusted for future borrowing undernon-cash items of $11.9 million for depreciation and amortization of our property and equipment and intangible assets, $10.3 million of share-based compensation expense, and $6.5 million in unrealized foreign currency gains on foreign denominated transactions primarily, intercompany balances. The drivers of the line of credit.

Operating Activitieschanges in operating assets and liabilities were a $29.1 million increase in deferred revenue, a $4.9 million increase in accrued expenses and other liabilities, a $1.9 million decrease in other assets and a $0.8 million increase in accounts payable, partially offset by a $11.8 million increase in accounts receivable and a $2.8 million increase in prepaid expenses and other current assets.

The primary factors affecting our operating cash flows during the period were our net loss of $3.2 million, adjusted for non-cash items of $10.5 million for depreciation and amortization of our property and equipment, $7.9 million of share-based compensation expense, and $1.0 million in net foreign currency gains. The primary drivers of the changes in operating assets and liabilities were an $18.6 million increase in deferred revenue and a $4.7 million increase in accrued expenses and other liabilities, partially offset by a $9.8 million increase in accounts receivable, a $2.2 million increase in prepaid expenses and other current assets, a $0.5 million decrease in accounts payable and a $0.4 million increase in other assets.

For the year ended March 31, 2015, cash provided by operating activities was $23.2 million.

The primary drivers of the changes in operating assets and liabilities were an $11.4 million increase in deferred revenue, a $2.8 million increase in accrued expenses and other liabilities, and a $0.7 million decrease in prepaid expenses and other current assets, partially offset by a $4.3 million increase in accounts receivable due primarily to overall growth in our business.

ForInvesting activities

The primary factors affecting our operating cash flows during this period were our net loss2017 consisted of $16.9 million, adjusted for non-cash charges of $9.0 million for depreciation and amortization of our property and equipment, $1.2 million of share-based compensation and $2.3$67.6 million in net foreign currency losses. The primary driverspurchases of investments, $18.5 million in capital expenditures and $5.6 million in payments related to the changes in operating assets and liabilities were an $8.8 million increase in deferred revenue and a $2.9 million increase in accrued expenses and other liabilities,iSheriff acquisition partially offset by a $6.6$7.0 million increase in accounts receivable, and a $1.7 million increase in other assets. The increase in accrued expenses and other current liabilities was attributable primarily to the timingmaturities of our cash payments and the increase in accounts receivable attributable primarily to overall growth in our business.

investments.  Cash used in investing activities of $14.2 million $12.6 million and $17.9$12.6 million for the years ended March 31, 2016 2015 and 2014,2015, respectively, was due to capital expenditures. Our capital expenditures were associated primarily with computer equipment purchased in support of our expanding infrastructure.infrastructure and to a lesser extent leasehold improvements and office equipment associated with increased headcount.


Financing activities

Financing ActivitiesCash used in financing activities of $0.3 million for the year ended March 31, 2017 was primarily due to payments on debt of $4.6 million and payments on capital lease obligations of $0.2 million, partially offset by $4.5 million of proceeds from exercises of share options.  

Cash provided by financing activities of $63.8 million for the year ended March 31, 2016 was due primarily to $68.3 million in proceeds from the initial public offering,our IPO, net of issuance costs, and $0.9 million of proceeds from exercises of share options, partially offset by payments on debt of $5.4 million.

Cash used in financing activities of $0.2 million for the year ended March 31, 2014 was due primarily to payments on debt.

Net Operating Loss Carryforwardsoperating loss carryforwards

As of March 31, 2017 and 2016, we had U.K. net operating loss carryforwards for U.S. federal income tax purposes of approximately $31.5 million.$23.7 million and $10.3 million, respectively that do not expire. As of March 31 2017 and 2016, we had U.S. federal net operating loss carryforwards forof approximately $28.0 million and $31.5 million, respectively and U.S. state income tax purposes of approximately $24.4 million. These net operating loss carryforwards of approximately $18.9 million and $24.4 million, respectively that expire at various dates through 2036. In addition, as2037. As of March 31, 2017 and 2016, we had Australian net operating loss carryforwards in the U.K. and our other non-U.S. locations of approximately $10.3$11.9 million and $7.7 million, respectively.respectively that do not expire. As of March 31, 2017, the Company had a U.K. income tax credit carryforward of $0.3 million that does not expire and a $0.1 million U.S. Federal tax credit that does not expire.

In March 2016, the FASB issued ASU 2016-09, Compensation - Stock Compensation. The non-U.S.amendments require an entity to recognize all excess tax benefits and tax deficiencies in connection with share-based compensation as income tax expense or benefit in the income statement. The amendments also require recognizing excess tax benefits regardless of whether the benefit reduces taxes payable in the current period and excess tax benefits will be classified as an operating loss carryforwardsactivity in the statement of cash flows. The tax effects of exercised or vested awards will be treated as discrete items in the reporting period in which they occur. The amendments are unlimited in duration.effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2016. This guidance will be adopted by the Company on April 1, 2018 using a modified retrospective transition method; however the adoption is not expected to have a material impact to the Company’s deferred tax assets or retained earnings on its consolidated balance sheets.

In assessing our ability to realize our net deferred tax assets, we considered various factors including future reversals of existing taxable temporary differences, projected future taxable income, tax planning strategies and recent financial operations, to determine whether it is more likely than not that some portion or all of our net deferred tax assets will not be realized. Based upon these factors, we have determined that the uncertainty regarding the realization of these assets is sufficient to warrant the need for a full valuation allowance against our net deferred tax assets.

Off-Balance Sheet ArrangementsOff-balance sheet arrangements

Up to and including the 2016, 2015 and 2014 fiscal years,year ended March 31, 2017, we have not had any relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special purpose entities, which would have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes. As a result, we are not exposed to related financing, liquidity, market or credit risks that could arise if we had engaged in those types of arrangements.

Recently Issuedissued and Adopted Accounting Pronouncementsadopted accounting pronouncements

For information on recent accounting pronouncements, see Recently Issued Accounting Pronouncements in the notes to the consolidated financial statements appearing elsewhere in this Annual Report on Form 20-F.

Critical Accounting Policiesaccounting policies and Estimatesestimates

Our consolidated financial statements and the related notes included elsewhere in this Annual Report on Form 20-F are prepared in accordance with accounting principles generally accepted in the United States. The preparation of

these consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Changes in accounting estimates are reasonably likely to occur from period to period. Accordingly, actual results could differ significantly from our estimates. We evaluate our estimates and assumptions on an ongoing basis. To the extent that there are material differences between our estimates and our actual results, our future financial statement presentation, financial condition, results of operations and cash flows will be affected.

We believe that of our significant accounting policies, which are described in Note 2 to the notes to our consolidated financial statements included elsewhere in this Annual Report on Form 20-F, the following accounting policies involve a greater degree of judgment and complexity. Accordingly, these are the policies we believe are the most critical to aid in fully understanding and evaluating our consolidated financial condition and results of our operations.

Under the JOBS Act, an emerging growth company can take advantage of an extended transition period for complying with new or revised accounting standards. This provision allows an emerging growth company to delay the adoption of some accounting standards until those standards would otherwise apply to private companies. However, we have irrevocably chosen to “opt out” of such extended transition period, and as a result, we will comply with new or revised accounting standards on the relevant dates on which adoption is required for non-emerging growth companies.

Revenue Recognition

We derive our revenue from two sources: (1) subscription revenues, which are comprised of subscription fees from customers accessing our cloud services and from customers purchasing additional support beyond the standard support that is included in the basic subscription fees; and (2) related professional services and other revenue, which consists primarily of set-up and ingestion andfees as well as training fees.

We recognize revenue when all of the following conditions are satisfied:

there is persuasive evidence of an arrangement;

the service has been or is being provided to the customer;

the collection of the fees is probable; and

the amount of fees to be paid by the customer is fixed or determinable.

Our subscription arrangements provide customers with the right to access itsour hosted software applications. Customers do not have the right to take possession of our software during the hosting arrangement. Accordingly, we recognize revenue in accordance with ASC 605,Revenue Recognition, and Staff Accounting Bulletin (SAB) No. 104,Revenue Recognition.


We sell our products and services directly through our dedicated sales force and also indirectly through third-party resellers. In accordance with the provisions of ASC 605, we have considered certain factors in determining whether the end-user or the third-party reseller is our customer in arrangements involving resellers. We concluded that in the majority of transactions with resellers, the reseller is our customer. In these arrangements, we considered that it is the reseller, and not us, that has the relationship with the end-user. Specifically, the reseller has the ability to set pricing with the end-user and the credit risk with the end-user is borne by the reseller. Further, the reseller is not obligated to report its transaction price with the end-user to us, and in the majority of transactions, we are unable to determine the amount paid by the end-user customer to the reseller in these transactions. As a result of such considerations, revenue for these transactions is presented in the accompanying consolidated statements of operations based upon the amount billed to the reseller. For

transactions where we have determined that the end-user is the ultimate customer, revenue is presented in the accompanying consolidated statements of operations based on the transaction price with the end-user.

We recognize subscription and support revenue ratably over the term of the contract, typically one year in duration, beginning on the commencement date of each contract.

Amounts that have been invoiced are recorded in accounts receivable and in deferred revenue or revenue, depending on whether the revenue recognition criteria have been met.

Our professional services contracts are on a time and material basis. When these services are not combined with subscription revenues as a single unit of accounting, as discussed below, we recognize these revenues as the services are rendered.

Revenue is presented net of any taxes collected from customers.

We may enter into arrangements with multiple-deliverables that generally include multiple subscriptions, premium support and professional services. For arrangements with multiple deliverables, we evaluate each deliverable to determine whether it represents a separate unit of accounting based on the following criteria: (a) whether the delivered item has value to the customer on a stand-alone basis; and (b) if the contract includes a general right of return relative to the delivered item, whether delivery or performance of the undelivered items is considered probable and substantially within our control.

If the deliverables are determined to qualify as separate units of accounting, consideration is allocated to each unit of accounting based on the units’ relative selling prices. We determine the relative selling price for a deliverable based on its vendor-specific objective evidence of fair value, (VSOE),or VSOE, if available, or its best estimate of selling price, (BESP), if VSOE is not available. We have determined that third-party evidence of selling price (TPE) is not a practical alternative due to differences in itsour service offerings compared to other parties and the availability of relevant third-party pricing information. The amount of revenue allocated to delivered items is limited by contingent revenue, if any.

Subscription services have standalone value as such services are often sold separately. In determining whether professional services sold together with the subscription services have standalone value, we consider the following factors for each professional services agreement: availability of the services from other vendors, the nature of the professional services, the determination that customers cannot resell the services that Mimecast provides, the timing of when the professional services contract was signed in comparison to the subscription service start date and the contractual dependence of the subscription service on the customer’s satisfaction with the professional services work. Professional services sold at the time of the multiple-element subscription arrangement typically include customer set-up and ingestion services. To date, we have concluded that all of these professional services included in executed multiple-deliverable arrangements do not have standalone value and are therefore not considered separate units of accounting. These professional services are purchased by customers only in contemplation of, or in concert with, purchasing one of our corehosted subscription servicessolutions and, therefore, are not considered a substantive service, such that the provision of such service does not reflect the culmination of the earnings process. Mimecast does not sell these services without the related underlying primary subscription as there would be no practical interest or need on the behalf of a customer to buy these services without the underlying subscription. We do not have any knowledge of other vendors selling these services on a stand-alone basis and there is no way for an end-user to resell the deliverable. Accordingly, the deliverables within the arrangement including both subscription services and other professional services are accounted for as a single unit of accounting. On these occasions, revenue for the professional services deliverables in the arrangement is recognized on a straight-line basis over the contractual term or the average customer life, as further described below.

Deferred revenue primarily consists of billings or payments received in advance of revenue recognition from subscription services described above and is recognized as the revenue recognition criteria are met. In

addition, deferred revenue consists of amounts paid by customers related to upfront set-up or ingestion fees. Revenue related to such services is recognized over the contractual term or the average customer life, whichever is longer. The estimated customer life has been determined to be five years.


Deferred revenue that is expected to be recognized during the succeeding twelve month period is recorded as current deferred revenue and the remaining portion is recorded as non-current in the accompanying consolidated balance sheets.

Income Taxestaxes

We are subject to income tax in the United Kingdom, the United States and other international jurisdictions, and we use estimates in determining our provision for income taxes. We account for income taxes in accordance with ASC 740,Income Taxes. ASC 740 is an asset and liability approach that requires recognition of deferred tax assets and liabilities for the expected future tax consequences attributable to differences between the carrying amounts of assets and liabilities for financial reporting purposes and their respective tax basis, and for net operating loss and tax credit carryforwards. ASC 740 requires a valuation allowance against net deferred tax assets if, based upon the available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized. In making such determination, we consider all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax planning strategies and recent financial operations. Realization of deferred tax assets is dependent upon future earnings, if any, the timing and amount of which are uncertain. Accordingly, the net deferred tax assets have been fully offset by a valuation allowance.

We recognize the tax benefit from an uncertain tax position only if it is more likely than not the tax position will be sustained on examination by the tax authorities, based on the technical merits of the position. The tax benefits recognized in the consolidated financial statements from such position are then measured based on the largest benefit that has a greater than 50% likelihood of being realized upon settlement. AtAs of March 31, 20162017 and 2015,2016, we did not have any uncertain tax positions that would impact our net tax provision.provision if recognized.

Accounting for Share-Based Compensation Awardsshare-based compensation awards

We account for share-based compensation awards in accordance with the provisions of ASC 718,Compensation—Stock Compensation, which requires the recognition of expense related to the fair value of share-based compensation awards in the statements of operations. For share options issued under our share-based compensation plans to employees and members of our Board of Directors for their services on the Board,as directors, the fair value of each option grant is estimated on the date of grant, and an estimated forfeiture rate is used when calculating share-based compensation expense for the period. For restricted share awards and restricted share units issued under our share-based compensation plans, the fair value of each grant is calculated based on the fair value of our ordinary shares on the date of grant. For service-based awards, we recognize share-based compensation expense on a straight-line basis over the requisite service period of the award. For awards subject to both performance and service-based vesting conditions, we recognize share-based compensation expense using an accelerated recognition method when it is probable that the performance condition will be achieved. Forfeitures are required to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. For share-based awards classified as liabilities, we account for such liability such that the compensation expense will be remeasured at each reporting date until such award is settled.

Certain awards granted by us are subject to service-based vesting conditions and a performance-based vesting condition based on a liquidity event, defined as either a change of control or an initial public offering. As a result, no compensation cost related to share-based awards with these performance conditions had been recognized through the date of the Company’sour IPO, which occurred in November 2015, as the Companywe had determined that a liquidity event was not probable. UponSince the closing of theour IPO, share-based compensation expense for these equity-awards ishas been recognized using the accelerated attribution method over the remaining service period.

We estimate the fair value of employee share options on the date of grant using the Black-Scholes option-pricing model, which requires the use of highly subjective estimates and assumptions. We estimate the expected term of options for service-based awards utilizing the “Simplified Method,” as the Company doeswe do not have sufficient historical share option exercise information on which to base its estimate. The Simplified Method is based on the average of the vesting tranches and the contractual life of each grant. In addition, the expected term for certain share-based awards which are subject to service-based and performance-based vesting conditions, is based on management’s estimate of the period of time for which the instrument is expected to be outstanding, factoring in certain assumptions such as the vesting period of the award, length of service and/or the location of the employee. The risk-free interest rate is based on a treasury instrument whose term is consistent with the expected life of the share option. Since there was no public market for itsour ordinary shares prior to the IPO and as our shares have been publicly traded for a limited time, we determined the expected volatility for options granted based on an analysis of reported data for a peer group of companies that issue options with substantially similar terms. The expected volatility of options granted has been determined using an average of the historical volatility measures of this peer group of companies. We use an expected dividend rate of zero as we currently have no history or expectation of paying dividends on our ordinary shares. In addition, we have estimated expected forfeitures of share options based on our historical forfeiture rate and used these rates in developing a future forfeiture rate. If our actual forfeiture rate varies from our historical rates and estimates, additional adjustments to compensation expense may be required in future periods. Since the IPO, the fair value of our ordinary shares at the time of each grant of a share-based award have been based on the market value at the time of each grant.


Prior to the IPO, in the absence of an active market for our ordinary shares, the Board of Directors, the members of which we believe have extensive business, finance, and venture capital experience, were required to estimate the fair value of the our ordinary shares at the time of each grant of a share-based award. We and the Board of Directors utilized various valuation methodologies in accordance with the framework of the American Institute of Certified Public Accountants’ Technical Practice Aid, Valuation of Privately-Held Company Equity Securities Issued as Compensation, to estimate the fair value of its ordinary shares. Each valuation methodology included estimates and assumptions that required our judgment. These estimates and assumptions include a number of objective and subjective factors, in determining the value of our ordinary shares at each grant date, including the following factors: (1) prices paid for our convertible preferred shares, which we had sold to outside investors in arm’s-length transactions, and the rights, preferences, and privileges of our convertible preferred shares and ordinary shares; (2) valuations performed by an independent valuation specialist; (3) our stage of development and revenue growth; (4) the fact that the grants of share-based awards involved illiquid securities in a private company; and (5) the likelihood of achieving a liquidity event for the ordinary shares underlying the share-based awards, such as an IPO or sale of the Company, given prevailing market conditions.

We believe this methodology to be reasonable based upon our internal peer company analyses, and further supported by several arm’s-length transactions involving the convertible preferred shares. As our ordinary shares were not actively traded prior to the IPO, the determination of fair value involves assumptions, judgments and estimates. If different assumptions were made, share-based compensation expense, consolidated net (loss) income and consolidated net (loss) income per share could have been significantly different.

Since the IPO, the fair value of our ordinary shares at the time of each grant of a share-based award have been based on the market value at the time of each grant.

The following table presents the weighted-average assumptions used to estimate the fair value of options granted to employees during each of the periods indicated below:

JOBS Act

In April 2012, the JOBS Act was signed into law. The JOBS Act contains provisions that, among other things, reduce certain reporting requirements for an “emerging growth company.” As an “emerging growth company,” we have irrevocably elected not to take advantage of the extended transition period afforded by the JOBS Act for the implementation of new or revised accounting standards, and as a result, we will comply with new or revised accounting standards on the relevant dates on which adoption of such standards is required for non-emerging growth companies. Section 107 of the JOBS Act provides that our decision to not take advantage of the extended transition period for complying with new or revised accounting standards is irrevocable. In addition, we are in the process of evaluating the benefits of relying on the other exemptions and reduced reporting requirements provided by the JOBS Act.

Subject to certain conditions set forth in the JOBS Act, if as an “emerging growth company” we choose to rely on such exemptions, we may not be required to, among other things, (i) provide an auditor’s attestation report on our system of internal controls over financial reporting pursuant to Section 404 of the Sarbanes-Oxley Act, (ii) provide all of the compensation disclosure that may be required of non-emerging growth public companies under the Dodd-Frank Wall Street Reform and Consumer Protection Act, (iii) comply with any requirement that may be adopted by the PCAOBPublic Company Accounting Oversight Board regarding mandatory audit firm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements (auditor discussion and analysis), or (iv) disclose certain executive compensation-related items such as the correlation between executive compensation and performance and comparisons of our chief executive officer’s compensation to median employee compensation.

These exemptions will apply for a period of five years following the completion of our initial public offeringIPO, which occurred in November 2015 or until we no longer meet the requirements of being an “emerging growth company,” whichever is earlier.

C. Board practices

C.Board Practices

Board Composition

We comply with the rule of the NASDAQ Stock Market rule that a majority of our directors be independent. Our board of directors has determined that all of our directors, other than our Chief Executive Officer and Chief Technology Officer, are independent under such rules.

Our board of directors is responsible for overall corporate governance and for supervising the general affairs and business of our company and its subsidiaries.

Our board is responsible for the proper management of our company and its subsidiaries and setting the overall direction and strategy of our group, reviewing scientific, operational and financial performance, and advising on management appointments. All key operational and investment decisions are subject to board approval.

Our board of directors currently believes that our company is best served by combining the roles of Chairman of the Board and Chief Executive Officer, coupled with a lead independent director. Our board of directors believes that as Chief Executive Officer, Mr. Bauer is the director most familiar with our business and industry and most capable of effectively identifying strategic priorities and leading discussion and execution of strategy. Our independent directors bring experience, oversight and expertise from outside our company, while our Chief Executive Officer brings company-specific experience and expertise. Our board of directors believes that the combined role of Chairman and Chief Executive Officer is the best leadership structure for us at the current time as it promotes the efficient and effective development and execution of our strategy and facilitates information flow between management and our board of directors. The board of directors recognizes, however, that no single leadership model is right for all companies at all times. Our corporate governance guidelines provide that the board of directors should be free to choose a chairperson of the board based upon the board’s view of what is in the best interests of our company. Accordingly, the board of directors periodically reviews its leadership structure.


In August 2015, our board of directors appointed Christopher FitzGerald serves as lead independent director. As the lead independent director, Mr. FitzGerald is responsible for coordinating the activities of the independent directors. Among other things, the lead independent director has the following specific responsibilities:

preside at all meetings of the board of directors at which the chairperson is not present, including executive sessions of the independent directors;

call special meetings of the independent directors;

act as the principal liaison between the independent directors and the chairperson of the board;

approve meeting schedules to assure that there is sufficient time for discussion of all agenda items and approve meeting agendas for the board of directors and its committees;

approve information sent to the board; and

perform such other duties as the board of directors may from time to time delegate to the lead independent director.

Role of Board in Risk Oversight Process

Risk assessment and oversight are an integral part of our governance and management processes. Our board of directors encourages management to promote a culture that incorporates risk management into our corporate strategy and day-to-day business operations. Management discusses strategic and operational risks at regular management meetings, and conducts specific strategic planning and review sessions during the year that include a focused discussion and analysis of the risks facing us. Throughout the year, senior management reviews these risks with the board of directors at regular board meetings as part of management presentations that focus on particular business functions, operations or strategies, and presents the steps taken by management to mitigate or eliminate such risks.

Corporate Governance and Committees of the Board

Corporate Governancegovernance

The Sarbanes-Oxley Act, of 2002, as well as related rules subsequently implemented by the SEC, requires foreign private issuers, including our company, to comply with various corporate governance practices. In addition, NASDAQ rules provide that foreign private issuers may follow home country practice in lieu of the NASDAQ corporate governance standards, subject to certain exceptions and except to the extent that such exemptions would be contrary to U.S. federal securities laws. We currently do not, and do not intend to, take advantage of any such exemptions.

We intend to take all actions necessary for us to maintain compliance as a foreign private issuer under the applicable requirements of the rules adopted by the SEC, but expect to transition to domestic issuer status following the fiscal year ending March 31, 2017.2018.

Because we are a foreign private issuer, our directors and senior managementexecutive officers are not subject to short-swing profit and insider trading reporting obligations under Section 16 of the U.S. Securities Exchange Act of 1934, as amended, or Exchange Act. They will, however, be subject to the obligations to report changes in share ownership under Section 13 of the Exchange Act and related SEC rules.


Committees of the Boardboard

We have established an audit committee, a compensation committee and a nominating and corporate governance committee and have a charter for each of these committees, current copies of which are available at the Corporate Governanceinvestor relations section of our website at investors.mimecast.com.www.mimecast.com.

Audit Committeecommittee

The members of our audit committee are Hagi Schwartz, Norman Fiore and Christopher FitzGerald and Bernard Dallé.FitzGerald. Hagi Schwartz is the chair of the audit committee. Our audit committee’s responsibilities include:

appointing, approving the compensation of, and assessing the independence, objectivity and effectiveness of our independent registered public accounting firm;

overseeing the work of our independent registered public accounting firm, including through the receipt and consideration of reports from that firm;

monitoring the integrity of our financial statements by reviewing and discussing with management and our independent registered public accounting firm our annual and quarterly financial statements and related disclosures;

reviewing and monitoring our internal control over financial reporting, disclosure controls and procedures and code of business conduct;

overseeing our risk assessment and risk management policies;

establishing policies regarding hiring employees from our independent registered public accounting firm and procedures for the receipt and retention of accounting related complaints and concerns;

meeting independently with our internal auditing staff, if any, our independent registered public accounting firm and management; and

reviewing and approving or ratifying any related person transactions.

All audit and non-audit services, other thande minimis non-audit services, to be provided to us by our independent registered public accounting firm must be approved in advance by our audit committee.

Our board of directors has determined that Hagi Schwartz is an “audit committee financial expert” as defined in Item 16A of Form 20-F.

In order to satisfy the independence criteria for audit committee members set forth in Rule 10A-3 under the Exchange Act, each member of an audit committee of a listed company may not, other than in his or her capacity as a member of the audit committee, the board of directors, or any other board committee, accept, directly or indirectly, any consulting, advisory, or other compensatory fee from the listed company or any of its subsidiaries or otherwise be an affiliated person of the listed company or any of its subsidiaries. We believe that the composition of our audit committee will meetmeets the requirements for independence under current NASDAQ and SEC rules and regulations.

Compensation Committeecommittee

The members of our compensation committee are Jeffrey Lieberman, Norman FioreAron Ain and Hagi Schwartz. Jeffrey Lieberman is the chair of the compensation committee. Our compensation committee’s responsibilities include:

reviewing and approving, or making recommendations to our board of directors with respect to, the compensation of our directors and executive management;

overseeing an evaluation of our executive management; and

overseeing and administering our employee share option scheme or equity incentive plans in operation from time to time.


In order to satisfy the independence criteria for compensation committee members set forth in Rule 10C-1 under the Exchange Act, all factors specifically relevant to determining whether a director has a relationship to such company which is material to that director’s ability to be independent from management in connection with the duties of a compensation committee member must be considered, including, but not limited to: (1) the source of compensation of the director, including any consulting advisory or other compensatory fee paid by such company to the director; and (2) whether the director is affiliated with the company or any of its subsidiaries or affiliates. We believe the composition of our compensation committee will meetmeets the requirements for independence under current NASDAQ and SEC rules and regulations.

Nominating and Corporate Governance Committeecorporate governance committee

The members of our nominating and corporate governance committee are Christopher FitzGerald, Aron Ain and Jeffrey Lieberman and Bernard Dallé.Lieberman. Christopher FitzGerald is the chair of the nominating and corporate governance committee. Our nominating and corporate governance committee’s responsibilities include:

identifying individuals qualified to become members of our board of directors;

Employment and Consulting Agreements

Executive Managementmanagement

Each of Peter Bauer and Peter Campbell has entered into an amended and restated employment agreement with Mimecast North America, Inc. and we have entered into a service agreement with Neil Murray. These agreements each contain customary provisions regarding non-competition, non-solicitation, confidentiality of information and assignment of inventions. The amended and restated employment agreements with each of Messrs. Bauer and Campbell provide for up to 12 months of base salary continuation and health insurance premiums in the event that the executive’s employment is terminated by us without “cause” or the executive resigns for “good reason.” In the event that such termination occurs within 12 months following a “change in control,” the executive will be entitled to receive a payment equal to 12 months of his then-current base salary (or his base salary in effect immediately prior to the change in control, if higher) plus his target bonus, up to 12 months of health insurance premiums and full acceleration of all equity awards. Receipt of the severance payments and benefits described above is conditioned upon the execution and effectiveness of a separation agreement, including a general release of claims in our favor. In addition, the amended and restated employment agreements provide that upon a change in control, 50% of the shares underlying all equity awards held by each of Messrs. Bauer and Campbell will accelerate and vest. Pursuant to the terms of the service agreement with Mr. Murray, we and Mr. Murray are each obligated to provide the other party with four months’ written notice to terminate the employment relationship. Alternatively, in lieu of providing four months’ notice, we may elect to pay Mr. Murray a lump sum equal to his base salary, bonus and benefits for the notice period. Such notice period and termination benefits do not apply in the event that Mr. Murray is terminated by us for any one of the reasons enumerated in his service agreement. Under the terms of Mr. Jennings’ offer letter, he is entitled to six months of base salary continuation and health insurance premiums in the event that his employment is terminated by us without “cause, ” subject to the execution by Mr. Jennings of a satisfactory release of claims.  In addition, his offer letter provides that upon a “change in control,”


50% of the shares underlying all unvested equity awards held by him will accelerate and vest. If he is terminated without “cause” or for certain other reasons within 12 months of such change in control, all remaining unvested equity awards will accelerate and vest.  Under the terms of Mr. Nault’s offer letter, he is entitled to nine months of base salary and target bonus continuation and health insurance premiums in the event that his employment is terminated by us or a successor company without “cause” or he resigns for “good reason,” subject to the execution by Mr. Nault of a satisfactory release of claims.  In addition, his offer letter provides that upon a “change in control,” 50% of the shares underlying all unvested equity awards held by him will accelerate and vest. If he is terminated without “cause” or he resigns for “good reason” within 12 months of such change in control, all remaining unvested equity awards will accelerate and vest.    

Non-Executive DirectorsNon-executive directors

Prior to our initial public offering, each of the members of our board of directors was elected pursuant to a subscription and shareholders’ agreement among us and certain of our existing shareholders. See “Major Shareholders and Related Party Transactions—Subscription and Shareholders’ Agreement.” That agreement terminated by its terms upon completion of our initial public offering,IPO, and there are no agreements between us and our shareholders governing the election of our directors.

Employee Share Plans

The equity incentive plans described in this section are the Mimecast Limited 2007 Key Employee Share Option Plan, or the 2007 Plan, the Mimecast Limited 2010 EMI Share Option Scheme, or the 2010 Plan, the Mimecast Limited Approved Share Option Plan, or the Approved Plan, the Mimecast Limited 2015 Share Option and Incentive Plan, or the 2015 Plan, and the Mimecast Limited 2015 Employee Share Purchase Plan, or the ESPP. Prior to our initial public offering,IPO, we granted awards to eligible participants under the 2007 Plan, the 2010 Plan and the Approved Plan. AfterSince the completion of our initial public offering,IPO, we have granted and expect to continue to grant awards to eligible participants under the 2015 Plan and our Board has authorized that the ESPP.

first six-month offering period under the ESPP will commence on July 1, 2017. We no longer grant awards under the 2007 Plan, the 2010 Plan and the Approved Plan.

2007 Plan

Our 2007 Plan was adopted by our board of directors on September 3, 2007. The maximum market value of shares (as of the date of grant) subject to unexercised Enterprise Management Incentive, or EMI, options granted under the 2007 Plan together with the 2010 Plan may not exceed £3 million. The 2007 Plan provides only for the granting of options to acquire Class B ordinary shares to our key employees and the key employees of our subsidiaries.

The 2007 Plan is administered by the non-executive members of our board of directors or a committee (administrator), who has the full power to interpret the 2007 Plan and to establish the rules and regulations applying to it and to make all other determinations they deem necessary or useful for the administration of the 2007 Plan, subject to applicable law. The option price of each option granted under the 2007 Plan was determined by the administrator of the 2007 Plan at the time the option was granted.

The 2007 Plan provides that, in the event of a change of control (as defined in the 2007 Plan) by way of trade sale, unless and to the extent that the administrator determines that the circumstances justify vesting and/or exercisability of a greater proportion of the unvested shares, (i) 75% of the shares underlying outstanding unvested options shall vest and the remaining 25% of the unvested option shares shall immediately lapse and (ii) options shall be exercisable to the extent that they have then vested and to the extent that any applicable performance conditions have then been satisfied. In such event, unless the acquirer provides for the replacement of such options, exercisable options may be exercised (a) on the same day as, and immediately prior to, the change of control becoming effective, (b) if the person making the offer so requests or makes it a condition of the offer that one or more optionholders is locked-in and the board of directors agreed to such request or requirement, in the 12-month period commencing no later than the date on which the acquirer gains control of us and any condition subject to which the offer was made has been satisfied or (c) in the absence of any such request or requirement, or if the board of directors does not agree to such request or requirement, within six months, or such longer period as the board of directors may determine (but in no event longer than 12 months), following the day on which the acquirer gains control of us and any condition subject to which the offer was made has been satisfied. Notwithstanding termination of an optionholder’s employment, any options vested at the time of a change of control shall immediately become exercisable for such period as the board of directors determined in its absolute discretion and acting fairly and reasonably if the board of directors determines that the termination is directly related to the change of control and exercisability is justified in the circumstances. InUnder the event of a2007 Plan, upon the listing of our shares on a recognized securities exchange that occurred on November 19, 2015, 100% of the unvested portion of options granted under the 2007 Plan shall vestvested and, unless the board of directors determines that the circumstances justify the exercisability of a greater proportion, 25% of the shares underlying options will becomewere exercisable immediately

upon the listing, 50% of the shares underlying options will becomewere exercisable 12 months following the date of the listing and 25% of the shares underlying options will become exercisable 24 months following the date of the listing.


The administrator may amend the 2007 Plan but no such action may adversely affect the terms of outstanding options under the 2007 Plan without the consent of the holders of 75% of the option shares then outstanding, whether vested or unvested.

2010 Plan

Our 2010 Plan was approved by our board of directors on March 23, 2010 and was most recently amended on April 28, 2015. The maximum value of shares subject to unexercised EMI options granted under the 2010 Plan together with the 2007 Plan may not exceed £3 million. The number of shares over which an EMI option may be granted to any one eligible employee is limited such that the total value of shares subject to unexercised EMI options granted by us or any group company does not exceed £1 less than £250,000.

The 2010 Plan is administered by our board of directors. The 2010 Plan permits us to make grants of (i) EMI options to our employees and employees of any qualifying subsidiary (as defined in the 2010 Plan) whose committed time (as defined in the 2010 Plan) amounts to at least 25 hours a week or, if less, 75% of his or her working time and who do not have a material interest (as defined in the 2010 Plan) in us or any of our subsidiaries and (ii) unapproved options to our employees and the employees of our subsidiaries. The option price of each option may not be less than the market value of the Class B ordinary shares on the date of grant and, in the case of an option that is a right to subscribe for Class B ordinary shares, may not be less than the nominal value of such shares. The term of each option may not exceed 10 years from the date of grant. Options granted under the 2010 Plan generally are not exercisable until the occurrence of an exit event, such as a corporate takeover, reconstruction, liquidation or sale of the business.

Under the 2010 Plan, options shall vestbecame vested in full immediately after our shares arewere admitted to listing on a recognized securities exchange. Such options shall becomebecame exercisable as to 25% of the underlying shares immediately following the admission date, 50% of the underlying shares on the first anniversary of the admission date and 25% of the underlying shares on the second anniversary of the admission date. However, options granted on or after May 13, 2014 to U.S. and South African participants shall continue vesting as set forth in the option award agreement.

The 2010 Plan provides that, in the event that a person obtains control (as defined in the 2010 Plan) of theour company as a result of (i) making an offer to acquire the whole of our issued share capital that is made on a condition such that, if satisfied, the person will have control of the company or (ii) negotiating a share sale and purchase agreement with our shareholders that contemplates that the person will obtain control of the company upon completion, 75% of the unvested shares underlying options under the 2010 Plan shall vest and the remaining 25% of the option shares will only be exercisable if the directors determine that the circumstances so justify. If replacement options are offered to optionholders under the 2010 Plan by the acquiring company in relation to vested options, and an optionholder does not agree to release the vested options and accept a replacement option, the board of directors shall determine whether such vested options shall be exercisable or whether they shall lapse. If replacement options are not offered to all optionholders, then vested options shall become exercisable in either of the following exercise periods, as determined by the administrator: (i) immediately before a change of control becoming unconditional or (ii) during the one-month exercise period starting at a date to be determined by the administrator (but in any event such period shall take place before the 12-month period following the date the change of control becomes unconditional).

Options may be exercised, to the extent vested, within 39 days of a court sanctioning a scheme of reconstruction (as defined in the 2010 Plan) or a sale of the business (as defined in the 2010 Plan).

The number of shares underlying options and the option price thereof shall be adjusted appropriately following any capitalization issue, rights issue, subdivision, consolidation or reduction of share capital. Our board of directors may amend or add rules to the 2010 Plan or impose additional conditions or requirements on options or the terms on which Class B ordinary shares are acquired; provided, however, no amendments may be made that would have the effect of causing EMI options to cease to be EMI options and no amendment may be made unless, (i) where the rights are enjoyed by a single optionholder and not by any other optionholder or class of optionholders, such optionholder provides written consent or, (ii) where the rights are enjoyed by all optionholders or any class of optionholders, with the consent of 75% of the shares underlying outstanding options.

The 2010 Plan shall automatically terminate on the tenth anniversary of its adoption date and our board of directors may terminate the 2010 Plan at any earlier time.


Approved Plan

Our Approved Plan was approved by our board of directors on October 24, 2012 and was approved by HM Revenue & Customs on November 14, 2012. It was most recently amended on April 28, 2015. The number of shares over which an option may be granted to any one eligible employee is limited such that the total market value of shares subject to unexercised options held by such person under the Approved Plan or any other share option plan approved by HM Revenue & Customs and adopted by us or any other associated company (as defined in the Approved Plan) shall not exceed £30,000.

The Approved Plan is administered by our board of directors and permits us to make grants of options to purchase our Class B ordinary shares to full-time directors or employees of subsidiaries (as defined in the Approved Plan). The term of each option may not exceed 10 years from the date of grant.

Except in certain limited circumstances, options under the Approved Plan may not be exercised earlier than the fourth anniversary of the date of grant, may only be exercised while the optionholder is a director or employee of a subsidiary, may only be exercised if any performance conditions have been fulfilled to the satisfaction of the administrator and may not be exercised at any time when a participant has or had, within the preceding 12 months a material interest (as defined in the Approved Plan) in a close company (as defined in the Approved Plan) which is the company or any company that has control of us or is a member of a consortium that owns the company.

The Approved Plan provides that, in the event that a person obtains control (as defined in the Approved Plan) of us as a result of (i) making a general offer to acquire the whole of our issued share capital that is made on a condition such that, if satisfied, the person will have control of the company or (ii) negotiating a share sale and purchase agreement with our shareholders that contemplates that the person will obtain control of the company upon completion, options may be exercised within six months of the date that the person obtains control of us or immediately before such period (i) to the extent vested and if any performance conditions have been satisfied to the satisfaction of the administrator or (ii) to the extent of 75% of the unvested shares underlying the option.

Under the Approved Plan, options granted before May 13, 2014 shall vestvested in full immediately after our shares are admitted to listing on a recognized securities exchange. Such options shall becomebecame exercisable as to 25% of the underlying shares immediately following the listing date, 50% of the underlying shares on the first anniversary of the listing date and 25% of the underlying shares on the second anniversary of the listing date. Options granted on or after May 13, 2014 shall continue vesting as set forth in the option award agreement.

The number of shares underlying options and the option price thereof shall be adjusted appropriately following any capitalization issue, any offer made by way of rights, subdivision, consolidation or reduction of share capital. Our board of directors may amend or add rules to the Approved Plan or impose additional

conditions or requirements on options or the terms on which Class B ordinary shares are acquired; provided, however, that no amendment may be made unless the consent of 75% of the shares underlying outstanding options is obtained.

2015 Plan

Our 2015 Plan was adopted by our board of directors on September 2, 2015 and approved by our shareholders on November 4, 2015 and became effective upon the closing of our initial public offering.IPO. The 2015 Plan allows the board of directors or the compensation committee to make equity-based incentive awards to our officers, employees, non-employee directors and consultants.

We have initially reserved a total of 5,500,000 shares, or the Initial Limit, for the issuance of awards under the 2015 Plan. This number is subject to adjustment in the event of a share split, share dividend or other change in our capitalization. The 2015 Plan provides that the number of shares reserved and available for issuance under the plan will automatically increase each January 1, beginning on January 1, 2016, by 5% of the outstanding number of ordinary shares on the immediately preceding December 31 or such lesser number of shares as determined by our board of directors. We refer to such number as the Annual Increase.

The shares we issue under the 2015 Plan will be authorized but unissued shares or shares that we reacquire. Ordinary shares underlying any awards that are forfeited, cancelled, held back upon exercise or settlement of an award to satisfy the exercise price or tax withholding, reacquired by us prior to vesting, satisfied without the issuance of shares, or are otherwise terminated (other than by exercise) under the 2015 Plan will be added back to the ordinary shares available for issuance under the 2015 Plan.


Share options and share appreciation rights with respect to no more than 2,500,000 ordinary shares may be granted to any one individual in any one calendar year. The maximum number of ordinary shares that may be issued as incentive share options may not exceed the Initial Limit cumulatively increased on January 1, 2016 and on each January 1 thereafter by the lesser of the Annual Increase or 2,750,000 shares. The value of all awards made under the 2015 Plan and all other cash compensation paid by us to any non-employee director in any calendar year shall not exceed $1,000,000.

The 2015 Plan will be administered by our compensation committee. Our compensation committee has full power to select, from among the individuals eligible for awards, the individuals to whom awards will be granted, to make any combination of awards to participants, and to determine the specific terms and conditions of each award, subject to the provisions of the 2015 Plan.

The 2015 Plan permits the granting of both options to purchase ordinary shares intended to qualify as incentive stock options under Section 422 of the Code and non-qualified stock options. The exercise price of each option will be determined by our compensation committee at the time of the grant but may not be less than 100% of the fair market value of our ordinary shares on the date of grant. The term of each option will be fixed by our compensation committee and may not exceed ten years from the date of grant. Our compensation committee will determine at what time or times each option may be exercised and may at any time accelerate the exercisability of all or a portion of any option.

Our compensation committee may award share appreciation rights subject to such conditions and restrictions as it may determine. Share appreciation rights entitle the recipient to ordinary shares equal to the value of the appreciation in our share price over the exercise price. The exercise price may not be less than 100% of the fair market value of our ordinary shares on the date of grant. The term of each share appreciation right will be fixed by our compensation committee and may not exceed ten years from the date of grant. Our compensation committee will determine at what time or times each share appreciation right may be exercised.

Our compensation committee may award restricted ordinary shares and restricted share units to participants subject to such conditions and restrictions as it may determine. These conditions and restrictions may include the

achievement of certain pre-established performance goals and/or continued employment with us through a specified period. Our compensation committee may also grant ordinary shares that are free from any restrictions under the 2015 Plan. Unrestricted shares may be granted to participants in recognition of past services or for other valid consideration and may be issued in lieu of cash compensation due to such participant.

Our compensation committee may grant performance share awards to participants that entitle the recipient to receive awards of ordinary shares upon the achievement of certain performance goals and such other conditions as our compensation committee shall determine. Our compensation committee may grant dividend equivalent rights to participants that entitle the recipient to receive credits for dividends that would have been paid if the recipient had held a specified number of ordinary shares.

Our compensation committee may grant cash awards under the 2015 Plan to participants, subject to the achievement of certain performance goals.

Our compensation committee may grant awards of restricted shares, restricted share units, performance share awards or cash-based awards under the 2015 Plan that are intended to qualify as “performance-based compensation” under Section 162(m) of the Code. Such awards will only vest or become payable upon the attainment of pre-determined performance goals that are established by our compensation committee and related to one or more performance criteria. The performance criteria that could be used with respect to any such awards include: total shareholder return, expense levels, earnings before interest, taxes, depreciation and amortization, or any elements thereof, net (loss) income (either before or after interest, taxes, depreciation and/or amortization), changes in the market price of our ordinary shares, economic value-added, sales or revenue, acquisitions or strategic transactions, operating income (loss), cash flow (including, but not limited to, operating cash flow and free cash flow), return on capital, assets, equity, or investment, shareholder returns, return on sales, gross or net profit levels, productivity, expense, margins, operating efficiency, customer satisfaction, working capital, earnings (loss) per share of our ordinary shares, sales or market shares and number of customers, any of which may be measured either in absolute terms or as compared to any incremental increase or as compared to results of a peer group. From and after the time that we become subject to Section 162(m) of the Code, the maximum award that is intended to qualify as “performance-based compensation” under Section 162(m) of the Code that may be made to certain of our officers during any twelve month period is 2,500,000 ordinary shares with respect to a share-based award and $15,000,000 with respect to a cash-based award.

The 2015 Plan provides that upon the effectiveness of a “sale event,” as defined in the 2015 Plan, an acquirer or successor entity may assume, continue or substitute outstanding awards under the 2015 Plan. To the extent that awards granted under the 2015 Plan are not assumed or continued or substituted by the successor entity, all options and share appreciation rights that are not exercisable immediately prior to the effective time of the sale event shall become fully exercisable as of the effective time of the sale event, all other awards with time-based vesting, conditions or restrictions, shall become fully vested and nonforfeitable as of the effective time of the sale event and all awards with conditions and restrictions relating to the attainment of performance goals may become vested and nonforfeitable in the discretion of the compensation committee and, upon the effective time of the sale event, all outstanding


awards granted under the 2015 Plan shall terminate. In the event of such termination, individuals holding options and share appreciation rights will be permitted to exercise such options and share appreciation rights (to the extent exercisable) within a specified period of time prior to the sale event. In addition, in connection with the termination of the 2015 Plan upon a sale event, we may make or provide for a cash payment to participants holding vested and exercisable options and share appreciation rights equal to the difference between the per share cash consideration payable to shareholders in the sale event and the exercise price of the options or share appreciation rights.

Our board of directors may amend or discontinue the 2015 Plan and our compensation committee may amend or cancel outstanding awards for purposes of satisfying changes in law or any other lawful purpose, but no such action may adversely affect rights under an award without the holder’s consent. Certain amendments to the 2015 Plan require the approval of our shareholders.

No awards may be granted under the 2015 Plan after the date that is ten years from the effective date of the 2015 Plan (or, with respect to incentive share options, after ten years from the date of the Board’s approval of the 2015 Plan). No awards under the 2015 Plan have been made prior to the date hereof.

ESPP

The ESPP was adopted by our board of directors on September 2, 2015 and approved by our shareholders on November 4, 2015. The ESPP initially reserves and authorizes for issuance a total of 1,100,000.1,100,000 shares. This number is subject to adjustment in the event of a share split, share dividend or other change in our capitalization.

Subject to applicable law, all employees whose customary employment is for more than 20 hours a week are eligible to participate in the ESPP. Any employee who owns 5% or more of the voting power or value of our ordinary shares is not eligible to purchase shares under the ESPP.

We may make one or more offerings each year to our employees to purchase shares under the ESPP, at the discretion of the administrator of the ESPP. Offerings will usually begin on each January and July and will continue for six-month periods, referred to as offering periods.

Each eligible employee may elect to participate in any offering by submitting an enrollment form at least 15 days before the relevant offering date.

Each employee who is a participant in the ESPP may purchase shares by authorizing payroll deductions from 1% to 10% of his or her eligible compensation during an offering period. Unless a participating employee has previously withdrawn from the offering, his or her accumulated payroll deductions will be used to purchase ordinary shares on the last business day of the offering period at a price equal to 85 % of the fair market value of the shares on the first business day or the last business day of the offering period, whichever is lower, provided that no more than 550,000 ordinary shares may be purchased by any one employee during each offering period. Under applicable tax rules, an employee may purchase no more than $25,000 worth of ordinary shares, valued at the grant date of the option to purchase such shares, under the ESPP in any calendar year.

An employee’s rights under the ESPP terminate upon voluntary withdrawal from the plan or when the employee ceases employment with us for any reason. We will promptly refund accumulated payroll deductions of an employee who has withdrawn from participation in the ESPP.

The ESPP may be terminated or amended by our board of directors at any time. An amendment that increases the number of ordinary shares authorized under the ESPP and certain other amendments require the approval of our shareholders.

Our board of directors has authorized that the first six-month offering period under the ESPP will commence on July 1, 2017.

Limitations on Liability and Indemnification Matters

To the extent permitted by the Jersey law, we are empowered to indemnify our directors against any liability they incur by reason of their directorship. See “Item 10—Share Capital—Limitation of Liability of Directors and Officers.” In addition, we maintain directors’ and officers’ insurance to insure such persons against certain liabilities.

ITEM 7. MAJOR SHAREHOLDERS AND RELATED PARTY TRANSACTIONS

A. Major Shareholdersshareholders

The following table sets forth information with respect to the beneficial ownership of our ordinary shares as of March 31, 20162017 of:

each of the members of our board of directors;directors (except that (i) Bernard Dallé is not included in the table as he resigned from the board of directors on April 1, 2017 and (ii) Aron Ain, who joined our board of directors on April 1, 2017, is included as a director);

each of our other executive officers; and

each person, or group of affiliated persons, who is known by us to beneficially own more than 5% of our ordinary shares;shares.

The column entitled “Shares Beneficially Owned—Percentage” is based on a total of 54,216,73855,901,996 ordinary shares outstanding as of March 31, 2016.2017, except as noted in the footnotes to the table.

As of March 31, 2016,2017, we had 4535 holders of record of our ordinary shares in the United States. These shareholders held in the aggregate 27,109,37244,895,060 of our outstanding ordinary shares, or 50%80% of our outstanding ordinary shares as of March 31, 2016.2017. The number of record holders in the United States is not representative of the number of beneficial holders nor is it representative of where such beneficial holders are resident since many of these ordinary shares were held by brokers or other nominees.

The amounts and percentages of ordinary shares beneficially owned are reported on the basis of regulations of the SEC governing the determination of beneficial ownership of securities. Under the applicable SEC rules, a person is deemed to be a “beneficial owner” of a security if that person has or shares voting power, which includes the power to vote or direct the voting of such security, investment power, which includes the power to dispose of or to direct the disposition of such security, or has the right to receive the economic benefit of ownership of the security. A person is also deemed to be a beneficial owner of any securities of which that person has a right to acquire beneficial ownership within 60 days, and such securities are considered outstanding for the purpose of calculating the percentage ownership of that person but not for the purpose of calculating the

percentage ownership of any other person. Under these rules, more than one person may be deemed beneficial owner of the same securities and a person may be deemed to be a beneficial owner of securities as to which such person has no economic interest.

The audit committee will review these transactions under our Code of Conduct, which governs conflicts of interests, among other matters, and is applicable to our employees, officers and directors.

Subscription and Shareholders’ AgreementRegistration rights

The Subscription and Shareholders’ Agreement terminated upon the completion of our initial public offering in November 2015.

Registration Rights

The holders of an aggregate of 29,366,09925,386,542 ordinary shares, or their permitted transferees, are entitled to rights with respect to the registration of these shares under the Securities Act. These rights are provided under the terms of a Registration Rights Agreement between us and the holders of these shares, which was entered into in connection with our convertible preference share financings, and include demand registration rights, short-form registration rights and piggyback registration rights.

Demand Registration Rightsregistration rights

Under the terms of the Registration Rights Agreement, we will be required, upon the written request of the holders of a majority of the shares that are entitled to rights under the Registration Rights Agreement, held by former holders of Series A preferred shares, Series B preferred shares and founder shares, including entities affiliated with each of the Insight Venture Partners, Index Ventures and Dawn Capital, to register all or a portion of these shares for public resale as soon as reasonably practicable within 60 days of such request. We are not required to effect a registration pursuant to this provision of the Registration Rights Agreement (i) during the period 60 days before our good faith estimate of a date of filing of, and ending 180 days after the effective date of, a registration initiated by us; (ii) after we have effected one registration pursuant to this provision of the Registration Rights Agreement at the request of former holders of Series A preferred shares or founder shares; (iii) after we have effected two registration statements pursuant to this provision of the Registration Rights Agreement at the request of former holders of Series B preferred shares; or (iv) if the initiating holders propose to dispose of securities that may be registered on Form S-3 or Form F-3. If such a registration is to be an underwritten offering, then the holders’ registration rights are conditioned upon such holders’ participation in such underwriting. We may defer the filing of a registration statement once during any twelve-month period for a period of not more than 120 days, if we provide a certificate signed by our chief executive officer stating that, in the good faith judgment of our board of directors, it would be materially detrimental to us and our shareholders for such registration statement to be effected at that time.


Short-Form Registration RightsShort-form registration rights

If we are eligible to file a registration statement on Form S-3 or Form F-3 and have not effected more than two such registrations within the preceding twelve-month period, these holders have the right, upon written notice to us of more than 10% of the shares entitled to rights under the Registration Rights Agreement held by former holders of Series A preferred shares, Series B preferred shares, or founder shares, including each of the Insight Venture Partners, Index Ventures and Dawn Capital entities, to have such shares registered by us as soon as reasonably practicable within 45 days of such request, if the proposed aggregate price of the shares to be registered by the holders requesting registration is at least $5.0 million. However, we may defer the filing of a registration statement once during any twelve-month period for a period of not more than 120 days, if we provide a certificate signed by our chief executive officer stating that, in the good faith judgment of our board of directors, it would be materially detrimental to us and our shareholders for such registration statement to be effected at that time.

Piggyback Registration Rightsregistration rights

If we register any of our securities for our own account, the holders of these shares are entitled to include their shares in the registration. If such registration is to be an underwritten offering, then the holders’ registration rights are conditioned on such holders’ participation in such underwriting.

Other Obligationsobligations

The registration rights are subject to certain conditions and limitations, including the right of the underwriters of an offering to limit the number of ordinary shares to be included in the registrations. We are generally required to bear the expense of all registrations, except underwriting discounts and commissions. The Registration Rights Agreement also contains the mutual commitment of us and the holders to indemnify each other for losses attributable to untrue statements or omission of a material fact or violations of the Securities Act or state securities laws incurred by us with registrations under the agreement.

Termination

The registration rights and our obligations thereunder terminate seven years after the closing of our initial public offeringIPO or, as to any individual holder, at such earlier time at which all shares held by such holder can be sold in any three-month period without registration in compliance with Rule 144 of the Securities Act.

Registration Statement on Form F-3

We have a filed a Registration Statement on Form F-3, commonly referred to as a “shelf registration,” that permits us to sell in a registered offering up to $50 million of our securities at our discretion.  In addition, the registration statement also covers the registration of 20,539,030 ordinary shares held by our existing shareholders, which includes a significant portion of the shares covered by the Registration Rights Agreement described above.  These shareholders could affect their rights under the Registration Rights Agreement by requiring that we initiate an offering under the registration statement. The shelf registration statement was declared effective by the SEC on March 14, 2017.  

Agreements with Officersofficers

We have entered into written employment agreements with each of Peter Bauer, Peter Campbell and Neil Murray. These agreementsMurray and offer letters with each contain customary provisions regarding non-competition, non-solicitation, confidentiality of informationEdward Jennings and assignment of inventions.Robert P.

We are party to an arrangement with Dawn Capital, a holder of more than 5% of our outstanding ordinary shares, pursuant to which we pay Dawn Capital an amount of £12,000 per annum for the services of Norman Fiore.Fiore as a member of our board of directors.

Secondary offering

All of the shares sold in the secondary offering were sold by our existing shareholders and we did not receive any proceeds from the sale of these shares.

ITEM 10. ADDITIONAL INFORMATION

A. Share Capitalcapital

The following descriptions are summaries of the material terms of our Articles of Association and Memorandum of Association. Reference is made to the more detailed provisions of the Articles of Association and Memorandum of Association. Please note that this summary is not intended to be exhaustive. For further information please refer to the full version of our Articles of Association and Memorandum of Association which is included as an exhibit to this Annual Report.Report on Form 20-F.

General

Our company was established under the laws of Jersey, Channel Islands, on July 28, 2015 with registered number 119119. Our register of members is kept at Queensway House, Hilgrove Street, St. Helier, Jersey JE1 1ES and our U.S. Branch register is held at 250 Royall Street, Canton, MA 02021. Our registered office is 22 Grenville Street, St. Helier, Jersey JE4 8PX. Our secretary is Peter CampbellRobert P. Nault and our assistant secretary is Mourant Ozannes Secretaries (Jersey) Limited. Under our Memorandum and Articles of Association, our authorized share capital consists of 300,000,000 ordinary shares, nominal value $0.012 per share and 5,000,000 preferred shares, nominal value $0.012 per share.


Issued Share Capital

Our issued share capital as of May 18, 201622, 2017 was 54,241,45256,361,225 ordinary shares with a nominal value of $0.012 per share and 0 preferred shares with a nominal value of $0.012 per share. Each issued ordinary share is fully paid. We currently have no deferred shares in our issued share capital.

Ordinary Shares

The holders of ordinary shares are entitled to receive dividends in proportion to the number of ordinary shares held by them. Holders of ordinary shares are entitled, in proportion to the number of ordinary shares held by them, to share in any surplus in the event of our winding up. The holders of ordinary shares are entitled to receive notice of, attend either in person or by proxy or, being a corporation, by a duly authorized representative, and vote at general meetings of shareholders.

Preferred Shares

Pursuant to Jersey law and our Memorandum and Articles of Association, our board of directors by resolution may establish one or more classes of preferred shares having such number of shares, designations, dividend rates, relative voting rights, liquidation rights and other relative participation, optional or other special rights, qualifications, limitations or restrictions as may be fixed by the board without any further shareholder approval. Such rights, preferences, powers and limitations as may be established would be preferential to the rights attaching to our ordinary shares and could also have the effect of discouraging an attempt to obtain control of us.

Options

As of May 18, 2016,22, 2017, there were options to purchase 8,043,6738,370,088 ordinary shares outstanding.

B. Memorandum and articles of association

B.Memorandum and Articles of Association

We incorporate by reference into this Annual Report on Form 20-F the description of our amended articles of association contained in our prospectus filed pursuant to Rule 424(b)(4) (File No. 333-207454) filed with the SEC on November 19, 2015.

Anti-Takeover Effects of Certain Provisions of Our Articles of Association

General

Our Articles of Association contain provisions that could have the effect of delaying, deterring or preventing another party from acquiring or seeking to acquire control of us. These provisions, as well as our ability to issue preferred shares, are designed to discourage certain types of coercive takeover practices and inadequate takeover bids. These provisions are also intended to encourage anyone seeking to acquire control of us to negotiate first with our board of directors. However, these provisions may also delay, deter or prevent a change in control or other takeovers of our company that our shareholders might consider to be in their best interests, including transactions that might result in a premium being paid over the market price of our ordinary shares and also may limit the price that investors are willing to pay in the future for our ordinary shares. These provisions may also have the effect of preventing changes in our management. We believe that the benefits of increased protection give us the potential ability to negotiate with the proponent of an unfriendly or unsolicited proposal to acquire or restructure us, and that the benefits of this increased protection outweigh the disadvantages of discouraging those proposals, because negotiation of those proposals could result in an improvement of their terms. A description of these provisions is set forth below.


Staggered Boardboard of Directorsdirectors

Our Articles of Association provide for a staggered board of directors consisting of three classes of directors. Directors of each class are chosen for three-year terms upon the expiration of their current terms and each year one class of our directors will be elected by our shareholders. The terms of the Class I, Class II and Class III directors will expire in 2016,2019, 2017 and 2018, respectively. Beginning in 2016, our shareholders will elect directors for three-year terms upon the expiration of their current terms. Our shareholders will elect only one class of directors each year. We believe that classification of our board of directors will help to ensure the continuity and stability of our business strategies and policies as determined by our board of directors. There is no cumulative voting in the election of directors. As such, this classified board provision could have the effect of making the replacement of incumbent directors more time-consuming and difficult. At least two annual meetings of shareholders, instead of one, will generally be required to effect a change in a majority of our board of directors. Thus, the classified board provision could increase the likelihood that incumbent directors will retain their positions. The staggered terms of directors also may delay, defer or prevent a tender offer or an attempt to change control of us, even though a tender offer or change in control might be believed by our shareholders to be in their best interest.

Issuance of Preferred Sharespreferred shares

The ability to authorize and issue preferred shares is vested in our board of directors, which makes it possible for our board of directors to issue preferred shares with voting or other rights or preferences that could impede the success of any attempt to change control of us. These and other provisions may have the effect of deterring hostile takeovers or delaying changes in control or management of our company.

No Shareholder Actionshareholder action by Written Consentwritten consent

Our Articles of Association provide that all shareholder actions are required to be taken by a vote of the shareholders at an annual or special meeting, and that shareholders may not take any action by written consent in lieu of a meeting. This limit may lengthen the amount of time required to take shareholder actions and would prevent the amendment of our Articles of Association or Memorandum of Association or removal of directors by our shareholders without holding a meeting of shareholders.

Advance Notice Procedurenotice procedure

Our Articles of Association provide an advance notice procedure for shareholders to nominate director candidates for election, including proposed nominations of persons for election to the board of directors. Subject to the rights of the holders of any series of preferred shares, only persons nominated by, or at the direction of, our board of directors or by a shareholder who has given proper and timely notice to our secretary prior to the meeting, will be eligible for election as a director. In addition, any proposed business other than the nomination of persons for election to our board of directors must constitute a proper matter for shareholder action pursuant to the notice of meeting delivered to us. For notice to be timely, it must be received by our secretary not less than 90 nor more than 120 calendar days prior to the first anniversary of the previous year’s annual meeting (or if the date of the annual meeting is advanced more than 30 calendar days or delayed by more than 60 calendar days from such anniversary date, not earlier than the 120th calendar day nor more than 90 days prior to such meeting or the 10th calendar day after public announcement of the date of such meeting is first made). These advance notice provisions may have the effect of precluding the conduct of certain business at a meeting if the proper procedures are not followed or may discourage or deter a potential acquirer from conducting a solicitation of proxies to elect its own slate of directors or otherwise attempt to obtain control of us.

Limitation of Liability of Directors and Officers

Our Articles of Association include provisions that indemnify, to the fullest extent allowable under Jersey law, the personal liability of directors or officers for monetary damages for actions taken as our director or officer, or for serving at our request as a director or officer or another position at another corporation or enterprise, as the case may be. However, exculpation does not apply if the directors acted in bad faith, knowingly or intentionally violated the law, authorized illegal dividends or redemptions or derived an improper benefit from their actions as directors. We will also be expressly authorized to advance certain reasonable expenses (including attorneys’ fees and disbursements and court costs) to our directors and officers and to carry directors’ and officers’ insurance to protect us, our directors, officers and certain employees for some liabilities.

We believe that the limitation of liability and indemnification provisions in our Articles of Association and the indemnification agreements will facilitate our ability to continue to attract and retain qualified individuals to serve as directors and officers.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers or persons controlling the registrant pursuant to the foregoing provisions, we have been informed that, in the opinion of the SEC, such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.


Other Jersey, Channel Islands Law Considerations

Purchase of Own Sharesown shares

As with declaring a dividend, we may not buy back or redeem our shares unless our directors who are to authorize the buyback or redemption have made a statutory solvency statement that, immediately following the date on which the buyback or redemption is proposed, the company will be able to discharge its liabilities as they fall due and, having regard to prescribed factors, the company will be able to continue to carry on business and

discharge its liabilities as they fall due for the 12 months immediately following the date on which the buyback or redemption is proposed (or until the company is dissolved on a solvent basis, if earlier).

If the above conditions are met, we may purchase shares in the manner described below.

We may purchase on a stock exchange our own fully paid shares pursuant to a special resolution of our shareholders adopted in November 2015.

We may purchase our own fully paid shares otherwise than on a stock exchange pursuant to a special resolution of our shareholders, but only if the purchase is made on the terms of a written purchase contract which has been approved by an ordinary resolution of our shareholders. The shareholder from whom we propose to purchase or redeem shares is not entitled to take part in such shareholder vote in respect of the shares to be purchased.

We may fund a redemption or purchase of our own shares from any source. We cannot purchase our shares if, as a result of such purchase, only redeemable shares would remain in issue.

If authorized by a resolution of our shareholders, any shares that we redeem or purchase may be held by us as treasury shares. Any shares held by us as treasury shares may be cancelled, sold, transferred for the purposes of or under an employee share scheme or held without cancelling, selling or transferring them. Shares redeemed or purchased by us are cancelled where we have not been authorized to hold these as treasury shares.

Mandatory Purchasespurchases and Acquisitionsacquisitions

The Jersey Companies Law provides that where a person has made an offer to acquire a class of all of our outstanding shares not already held by the person and has as a result of such offer acquired or contractually agreed to acquire 90% or more of such outstanding shares, that person is then entitled (and may be required) to acquire the remaining shares of such shares. In such circumstances, a holder of any such remaining shares may apply to the Jersey court for an order that the person making such offer not be entitled to purchase the holder’s shares or that the person purchase the holder’s shares on terms different to those under which the person made such offer.

Other than as described above and below under “U.K. City Code on Takeovers and Mergers,” we are not subject to any regulations under which a shareholder that acquires a certain level of share ownership is then required to offer to purchase all of our remaining shares on the same terms as such shareholder’s prior purchase.

Compromises and Arrangementsarrangements

Where we and our creditors or shareholders or a class of either of them propose a compromise or arrangement between us and our creditors or our shareholders or a class of either of them (as applicable), the Jersey court may order a meeting of the creditors or class of creditors or of our shareholders or class of shareholders (as applicable) to be called in such a manner as the court directs. Any compromise or arrangement approved by a majority in number representing 75% or more in value of the creditors or 75% or more of the voting rights of shareholders or class of either of them (as applicable) if sanctioned by the court, is binding upon us and all the creditors, shareholders or members of the specific class of either of them (as applicable).

Whether the capital of the company is to be treated as being divided into a single or multiple class(es) of shares is a matter to be determined by the court. The court may in its discretion treat a single class of shares as multiple classes, or multiple classes of shares as a single class, for the purposes of the shareholder approval referred to above taking into account all relevant circumstances, which may include circumstances other than the rights attaching to the shares themselves.

U.K. City Code on Takeovers and Mergers

The U.K. City Code on Takeovers and Mergers, or the Takeover Code, applies, among other things, to an offer for a public company whose registered office is in the Channel Islands and whose securities are not admitted to trading on a regulated market or a


multilateral trading facility in the United Kingdom or any stock exchange in the Channel Islands or the Isle of Man if the company is considered by the Panel on Takeovers and Mergers, or the Takeover Panel, to have its place of central management and control in the United Kingdom or the Channel Islands or the Isle of Man (in each case, a “Code Company”). This is known as the “residency test.” Under the Takeover Code, the Takeover Panel will determine whether we have our place of central management and control in the United Kingdom, the Channel Islands or the Isle of Man by looking at various factors, including the structure of our board of directors, the functions of the directors and where they are resident.

The Takeover Code provides a framework within which takeovers of companies subject to it are conducted. In particular, the Takeover Code contains certain rules in respect of mandatory offers for Code Companies. Under Rule 9 of the Takeover Code, if a person:

acquires an interest in shares of a Code Company that, when taken together with shares in which persons acting in concert with such person are interested, carry 30% or more of the voting rights of the Code Company; or

who, together with persons acting in concert with such person, is interested in shares that in the aggregate carry not less than 30% and not more than 50% of the voting rights in the Code, acquires additional interests in shares that increase the percentage of shares carrying voting rights in which that person is interested,

the acquirer, and, depending on the circumstances, its concert parties, would be required (except with the consent of the Takeover Panel) to make a cash offer (or provide a cash alternative) for the Code Company’s outstanding shares at a price not less than the highest price paid for any interests in the shares by the acquirer or its concert parties during the previous 12 months.

We currently do not anticipate being subject to the Takeover Code, as we intend to have our place of central management and control outside of the United Kingdom, the Channel Islands or the Isle of Man, but may in the future become subject to it due to changes in the board’s composition, changes in the Takeover Panel’s interpretation of the Takeover Code or other events.

Rights of Minority Shareholdersminority shareholders

Under Article 141 of the Jersey Companies Law, a shareholder may apply to court for relief on the grounds that the conduct of our affairs, including a proposed or actual act or omission by us, is “unfairly prejudicial” to the interests of our shareholders generally or of some part of our shareholders, including at least the shareholder making the application. What amounts to unfair prejudice is not defined in the Jersey Companies Law. There may also be common law personal actions available to our shareholders.

Under Article 143 of the Jersey Companies Law (which sets out the types of relief a court may grant in relation to an action brought under Article 141 of the Jersey Companies Law), the court may make an order regulating our affairs, requiring us to refrain from doing or continuing to do an act complained of, authorizing civil proceedings and providing for the purchase of shares by us or by any of our other shareholders.


Differences in Corporate Law

Set forth below is a comparison of certain shareholder rights and corporate governance matters under Delaware law and Jersey law:

 

Corporate Law Issue

Delaware Law

Jersey Law

Special Meetings of Shareholders

Shareholders generally do not have the right to call meetings of shareholders unless that right is granted in the certificate of incorporation or by-laws. However, if a corporation fails to hold its annual meeting within a period of 30 days after the date designated for the annual meeting, or if no date has been designated for a period of 13 months after its last annual meeting, the Delaware Court of Chancery may order a meeting to be held upon the application of a shareholder.

Shareholders holding 10% or more of the company’s voting rights and entitled to vote at the relevant meeting may legally require our directors to call a meeting of shareholders.

 

The Jersey Financial Services Commission, or JFSC, may, at the request of any officer, secretary or shareholder, call or direct the calling of an annual general meeting. Failure to call an annual general meeting in accordance with the requirements of the Jersey Companies Law is a criminal offense on the part of a Jersey company and its directors and secretary.

Interested Director Transactions

Interested director transactions are permissible and may not be legally voided if:

•   either a majority of disinterested directors, or a majority in interest of holders of shares of the corporation’s capital stock entitled to vote upon the matter, approves the transaction upon disclosure of all material facts; or

•   the transaction is determined to have been fair as to the corporation as of the time it is authorized, approved or ratified by the board of directors, a committee thereof or the shareholders.

An interested director must disclose to the company the nature and extent of any interest in a transaction with the company, or one of its subsidiaries, which to a material extent conflicts or may conflict with the interests of the company and of which the director is aware. Failure to disclose an interest entitles the company or a shareholder to apply to the court for an order setting aside the transaction concerned and directing that the director account to the company for any profit.

 

A transaction is not voidable and a director is not accountable notwithstanding a failure to disclose an interest if the transaction is confirmed by special resolution and the nature and extent of the director’s interest in the transaction are disclosed in reasonable detail in the notice calling the meeting at which the resolution is passed.

Corporate Law Issue

Delaware Law

Jersey Law

Although it may still order that a director account for any profit, a court will not set aside a transaction unless it is satisfied that the interests of third parties who have acted in good faith would not thereby be unfairly prejudiced and the transaction was not reasonable and fair in the interests of the company at the time it was entered into.

Cumulative Voting

The certificate of incorporation of a Delaware corporation may provide that shareholders of any class or classes or of any series may vote cumulatively either at all elections or at elections under specified circumstances.

There are no provisions in the Jersey Companies Law relating to cumulative voting.


Corporate Law Issue

Delaware Law

Jersey Law

Approval of Corporate Matters by Written Consent

Unless otherwise specified in a corporation’s certificate of incorporation, shareholders may take action permitted to be taken at an annual or special meeting, without a meeting, notice or a vote, if consents, in writing, setting forth the action, are signed by shareholders with not less than the minimum number of votes that would be necessary to authorize the action at a meeting. All consents must be dated and are only effective if the requisite signatures are collected within 60 days of the earliest dated consent delivered.

If permitted by the articles of association of a company, a written consent signed and passed by the specified majority of members may effect any matter that otherwise may be brought before a shareholders’ meeting, except for the removal of a company’s auditors. Such consent shall be deemed effective when the instrument, or the last of several instruments, is signed by the specified majority of members or on such later date as is specified in the resolution.

Business Combinations

With certain exceptions, a merger, consolidation or sale of all or substantially all of the assets of a Delaware corporation must be approved by the board of directors and a majority of the outstanding shares entitled to vote thereon.

A sale or disposal of all or substantially all the assets of a Jersey company must be approved by the board of directors and, only if the articles of association of the company require, by the shareholders in general meeting. A merger involving a Jersey company must be generally documented in a merger agreement which must be approved by special resolution of that company.

Delaware Law

Jersey Law

Limitations on Director’s Liability and Indemnification of Directors and Officers

A Delaware corporation may include in its certificate of incorporation provisions limiting the personal liability of its directors to the corporation or its shareholders for monetary damages for many types of breach of fiduciary duty. However, these provisions may not limit liability for any breach of the duty of loyalty, acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law, the authorization of unlawful dividends, stock purchases or redemptions, or any transaction from which a director derived an improper personal benefit. Moreover, these provisions would not be likely to bar claims arising under U.S. federal securities laws.

 

A Delaware corporation may indemnify a director or officer of the corporation against

expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred in defense of an action, suit or proceeding by reason of his or her position if (i) the director or officer acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the corporation and (ii) with respect to any criminal action or proceeding, the director or officer had no reasonable cause to believe his or her conduct was unlawful.

The Jersey Companies Law does not contain any provision permitting Jersey companies to limit the liabilities of directors for breach of fiduciary duty.

However, a Jersey company may exempt from liability, and indemnify directors and officers for, liabilities:

•   incurred in defending any civil or criminal legal proceedings where:

•   the person is either acquitted or receives a judgment in their favor;

•   where the proceedings are discontinued other than by reason of such person (or someone on their behalf) giving some benefit or suffering some detriment; or

•   where the proceedings are settled on terms that such person (or someone on their behalf) gives some benefit or suffers some detriment but in the opinion of a majority of the disinterested directors, the person was substantially successful on the merits in the person’s resistance to the proceedings;

•   incurred to anyone other than to the company if the person acted in good faith with a view to the best interests of the company;

•   incurred in connection with an application made to the court for relief from liability for negligence, default, breach of duty or breach of trust under Article 212 of the Jersey Companies Law in which relief is granted to the person by the court; or

•   incurred in a case in which the company normally maintains insurance for persons other than directors.

Corporate Law IssueAppraisal Rights

Delaware Law

Jersey Law

Appraisal RightsA shareholder of a Delaware corporation participating in certain major corporate transactions may, under certain circumstances, be entitled to appraisal rights under which the shareholder may receive cash in the amount of the fair value of the shares held by that shareholder (as determined by a court) in lieu of the consideration the shareholder would otherwise receive in the transaction.

No appraisal rights.

Shareholder Suits

Class actions and derivative actions generally are available to the shareholders of a Delaware corporation for, among other things, breach of fiduciary duty, corporate waste and actions not taken in accordance with applicable law. In such actions, the court has discretion to permit the winning party to recover attorneys’ fees incurred in connection with such action.

Under Article 141 of the Jersey Companies Law, a shareholder may apply to court for relief on the ground that the conduct of a company’s affairs, including a proposed or actual act or omission by a company, is “unfairly prejudicial” to the interests of shareholders generally or of some part of shareholders, including at least the shareholder making the application.

 

There may also be customary law personal actions available to shareholders. Under Article 143 of the Jersey Companies Law (which sets out the types of relief a court may grant in relation to an action brought under Article 141 of the Jersey Companies Law), the court may make an order regulating the affairs of a company, requiring a company to refrain from doing or continuing to do an act complained of, authorizing civil proceedings and providing for the purchase of shares by a company or by any of its other shareholders.

Inspection of Books and Records

All shareholders of a Delaware corporation have the right, upon written demand, to inspect or obtain copies of the corporation’s shares ledger and its other books and records for any purpose reasonably related to such person’s interest as a shareholder.

The register of shareholders and books containing the minutes of general meetings or of meetings of any class of shareholders of a Jersey company must during business hours be open to the inspection of a shareholder of the company without charge. The register of directors and

secretaries must during business hours (subject to such reasonable restrictions as the company may by its articles of association or in general meeting impose, but so that not less than two hours in each business day be allowed for inspection) be open to the inspection of a shareholder or director of the company without charge.

Amendments to Charter

Amendments to the certificate of incorporation of a Delaware corporation require the affirmative vote of the holders of a majority of the outstanding shares entitled to vote thereon or such greater vote as is provided for in the certificate of incorporation. A provision in the certificate of incorporation requiring the vote of a greater number or proportion of the directors or of the holders of any class of shares than is required by Delaware corporate law may not be amended, altered or repealed except by such greater vote.

The memorandum of association and articles of association of a Jersey company may only be amended by special resolution (being a two-third majority if the articles of association of the company do not specify a greater majority) passed by shareholders in general meeting or by written resolution signed by all the shareholders entitled to vote.

E. Taxation


Jersey Tax Considerations

The following summary of the anticipated tax treatment in Jersey of the holders of ordinary shares (other than holders of ordinary shares resident in Jersey) is based on Jersey taxation law as it is understood to apply at the date of this document. It does not constitute legal or tax advice. Holders of ordinary shares should consult their professional advisers on the implications of acquiring, holding or disposing of ordinary shares under the laws of the jurisdictions(s) in which they may be liable to taxation. Holders of ordinary shares should also be aware that tax laws, rules and practice and their interpretation may change.

Our affairs are, and are intended to continue to be, managed and controlled in the United Kingdom for tax purposes and therefore we are resident in the United Kingdom for U.K. and Jersey tax purposes.

We are not regarded as resident for tax purposes in Jersey, Channel Islands. On that basis, we are not subject to income tax in Jersey. However, if we derive any income from the renting or development of land in Jersey or the importation and supply of hydrocarbon oil into Jersey, such income will be subject to tax at the rate of 20%. It is not expected that we will derive any such income.

Withholding tax

Dividends on ordinary shares may be paid by us without withholding or deduction for or on account of Jersey income tax and holders of ordinary shares (other than residents of Jersey) will not be subject to any tax in Jersey in respect of the holding, sale or other disposition of such ordinary shares.

Save as regards Austria, the Taxation (Agreements with European Union Member States)(Jersey) Regulations 2005 (the “Regulations”) were suspended on 18 January 2016 pursuant to the Taxation (Agreements with European Union Member States)(Suspension of Regulations)(Jersey) Order 2016. The Regulations continue in effect until 31 December 2016 as regards Austria.

A paying agent established in Jersey that makes “interest payments” (as defined in the Regulations) to an individual beneficial owner resident in Austria prior to 1 January 2017 is obliged to communicate details of such payments to the Comptroller of Taxes in Jersey who will pass on such details to the tax authorities in Austria.

Goods and Services Tax

Jersey charges a tax on goods and services supplied in the Island (which we refer to as GST). We are an “international services entity” for the purposes of the Goods and Services Tax (Jersey) Law 2007 (the “GST Law”) and consequently, we are not required to:

 

(i)

register as a taxable person pursuant to the GST Law;

 

(ii)

charge goods and services tax in Jersey in respect of any supply made by us; or

 

(iii)

subject to limited exceptions that are not expected to apply to us, pay goods and services tax in Jersey in respect of any supply made to us.

Stamp Duty

In Jersey, no stamp duty is levied on the issue or transfer of the ordinary shares except that stamp duty is payable on Jersey grants of probate and letters of administration, which will generally be required to transfer ordinary shares on the death of a holder of such ordinary shares to the extent such ordinary shares are deemed to be movable property in Jersey. In the case of a grant of probate or letters of administration, stamp duty is levied according to the size of the estate (wherever situated in respect of a holder of ordinary shares domiciled in Jersey, or situated in Jersey in respect of a holder of ordinary shares domiciled outside Jersey) and is payable on a sliding scale at a rate of up to 0.75% of such estate.estate (subject to a maximum of £100,000).

Jersey does not otherwise levy taxes upon capital, inheritances, capital gains or gifts nor are there other estate duties.

U.K. Tax Considerations

The following statements are a general guide to certain aspects of current U.K. tax law and the current published practice of HM Revenue and Customs, both of which are subject to change, possibly with retrospective effect.

The following statements are intended to apply to holders of ordinary shares who are only resident for tax purposes in the U.K., who hold the ordinary shares as investments and who are the beneficial owners of the ordinary shares. The statements may not apply to certain classes of holders of ordinary shares, such as dealers in securities and persons acquiring ordinary shares in connection with their employment. Prospective investors in ordinary shares who are in any doubt as to their tax position regarding the acquisition, ownership and disposition of the ordinary shares should consult their own tax advisers.

Withholding tax

We will not be required to deduct or withhold U.K. tax at source from dividend payments we make.


Stamp duty and stamp duty reserve tax

No stamp duty reserve tax will be payable on the issue of the ordinary shares or on any transfer of our ordinary shares, provided that the ordinary shares are not registered in a register kept in the United Kingdom. It is not intended that such a register will be kept in the United Kingdom.

No stamp duty will be payable on the issue of the ordinary shares by us. No stamp duty will be payable on a transfer of our ordinary shares provided that (i) any instrument of transfer is not executed inside the United Kingdom, and (ii) such instrument of transfer does not relate to any property situated, or any matter or thing done or to be done, in the United Kingdom.

Dividends

Individuals

Please note that significant changes toChanges are being introduced in Finance (No. 2) Bill 2016 concerning the UK taxation of dividends for individual holders have taken effect onholders. These rules apply from April 6, 2016. What follows2016 and the following paragraphs are based on the expectation that the changes will be fully implemented when the Finance (No. 2) Bill 2016 is a summary of the rules inenacted.

With effect prior tofrom April 6, 2016. Please see2016, the following section titled“Changes to taxation of dividends for individuals”for more information.

An individual holder who receives a10% dividend from us will be entitled to a tax credit which may be set off against his total income tax liability on the dividend. Such anis abolished and a new £5,000 tax-free dividend allowance has been introduced. As a result, a United Kingdom resident individual holder’s liability to income tax is calculated on the aggregate of the dividend (the “declared dividend”) and the tax credit (such aggregate being the “gross dividend”) which will be regarded as the top slice of the individual’s income. The tax credit will be equal to 10% (2015/16) of the gross dividend (i.e. the tax credit will be one-ninth of the amount of the dividend).

An individual holder who is not liable to income tax in respect of the dividendshareholder will not be entitled to reclaim any part of the tax credit. An individual holder who is liable to income tax at the basic rate will be subject topay income tax on the first £5,000 of dividend at the rateincome they receive. The rates of 10% (2015/16) of the gross dividend so that the tax credit will satisfy in full such holder’s liability to income tax on the dividend.

An individual holder liable to income tax at the higher rate will be subject to income tax on the gross dividend at 32.5% (2015/16) of the gross dividend, but will be able to set the tax credit off against part of this liability. The effect of the set off of the U.K. tax credit is that such a holder will have to account for additional tax equal to 25% of the declared dividend.

An individual holder liable to income tax at the additional rate will be subject to income tax on the gross dividend at 37.5% (2015/16) of the gross dividend, but will be able to set the tax credit off against part of this liability. The effect of that set off of the U.K. tax credit is that such a holder will have to account for additional tax equal to approximately 30.6% of the declared dividend.

Changes to taxation of dividends for individuals

On April 6, 2016, legislation became effective, and was implemented, to abolishreceived above the dividend tax credit for individuals. The dividend tax credit has been replaced with a new tax-free allowance of £5,000 in dividend income per tax year. Dividend income in excess of the tax-free allowance will be taxed at the following rates:be:

 

(i)

7.5% (basicfor dividend income within the basic rate taxpayers);income tax band;

(ii)

32.5% for dividend income within the higher rate income tax band; and

 

(ii)

(iii)

32.5% (high

38.1% for dividend income within the additional rate taxpayers); andincome tax band.

(iii)38.1% (additional rate taxpayers).

The new legislation is part of the Finance Bill 2016.

Corporate shareholders within the charge to U.K. corporation tax

Holders of ordinary shares within the charge to U.K. corporation tax which are “small companies” for the purposes of Chapter 2 of Part 9A of the Corporation Tax Act 2009 (for the purposes of U.K. taxation of dividends) will not be subject to U.K. corporation tax on any dividend received from us provided certain conditions are met (including an anti-avoidance condition).

Other holders within the charge to U.K. corporation tax will not normally be subject to tax on dividends from us.

If the conditions for exemption are not met or cease to be satisfied, or such a holder elects for an otherwise exempt dividend to be taxable, the holder will be subject to U.K. corporation tax on dividends received from us, at the rate of corporation tax applicable to that holder.

A corporate holder resident in the U.K. who is not liable to tax on dividends from us will not be entitled to reclaim any part of the tax credit.

Capital gains

Individuals

For individual holders, the principal factors that will determine the U.K. capital gains tax position on a disposal or deemed disposal of ordinary shares are the extent to which the holder realizes any other capital gains in the U.K. tax year in which the disposal is made, the extent to which the holder has incurred capital losses in that or earlier U.K. tax years, and the level of the annual allowance of tax-free gains in that U.K. tax year (the “annual exemption”). The annual exemption for the 2015/20162017/2018 U.K. tax year is £11,100.£11,300.

If, after all allowable deductions, an individual holder’s taxable income for the year exceeds the basic rate U.K. income tax limit, a taxable chargeable gain accruing on a disposal or deemed disposal of the ordinary shares would be taxed at 28%20%. Otherwise, such a gain may be taxed at 18%10% or 28%20% or a combination of both rates.

Companies

A disposal or deemed disposal of ordinary shares by a holder within the charge to U.K. corporation tax may give rise to a chargeable gain or allowable loss for the purposes of U.K. corporation tax, depending on the

circumstances and subject to any available exemptions or reliefs. Corporation tax is charged on chargeable gains at the rate applicable to that company. Holders within the charge to


U.K. corporation tax will, for the purposes of computing chargeable gains, be allowed to claim an indexation allowance which applies to reduce capital gains (but not to create or increase an allowable loss) to the extent that such gains arise due to inflation.

Certain Material U.S. Federal Income Tax Considerations

The following is a summary of certain material U.S. federal income tax considerations relating to the acquisition, ownership and disposition of our ordinary shares by a U.S. holder (as defined below). This summary addresses only the U.S. federal income tax considerations for U.S. holders that hold such ordinary shares as capital assets. This summary does not address all U.S. federal income tax matters that may be relevant to a particular U.S. holder. This summary does not address tax considerations applicable to a holder of ordinary shares that may be subject to special tax rules including, without limitation, the following:

banks, financial institutions or insurance companies;

brokers, dealers or traders in securities, currencies, commodities, or notional principal contracts;

tax-exempt entities or organizations, including an “individual retirement account” or “Roth IRA” as defined in Section 408 or 408A of the Code (as defined below), respectively;

real estate investment trusts, regulated investment companies or grantor trusts;

persons that hold the ordinary shares as part of a “hedging,” “integrated” or “conversion” transaction or as a position in a “straddle” for U.S. federal income tax purposes;

partnerships (including entities classified as partnerships for U.S. federal income tax purposes) or other pass-through entities, or persons that will hold our shares through such an entity;

S corporations;

certain former citizens or long termlong-term residents of the United States;

persons that received our shares as compensation for the performance of services;

persons that acquireholding ordinary shares asin connection with a result of holdingtrade or owning our preferred shares;business conducted outside the United States;

holders that own directly, indirectly, or through attribution 10% or more of the voting power or value our shares; and

holders that have a “functional currency” other than the U.S. dollar.

Further, this summary does not address the U.S. federal estate, gift, or alternative minimum tax considerations, or any U.S. state, local, or non-U.S. tax considerations of the acquisition, ownership and disposition of our ordinary shares.

This description is based on the U.S. Internal Revenue Code of 1986, as amended, or the Code, existing, proposed and temporary U.S. Treasury Regulations promulgated thereunder and administrative and judicial interpretations thereof, in each case as in effect and available on the date hereof. All the foregoing is subject to change, which change could apply retroactively, and to differing interpretations, all of which could affect the tax considerations described below. There can be no assurances that the U.S. Internal Revenue Service, or the IRS, will not take a contrary position concerning the tax consequences of the acquisition, ownership and disposition of our ordinary shares or that such a position would not be sustained. Holders should consult their own tax advisers concerning the U.S. federal, state, local and non-U.S. tax consequences of acquiring, owning and disposing of our ordinary shares in their particular circumstances.

For the purposes of this summary, a “U.S. holder” is a beneficial owner of ordinary shares that is (or is treated as), for U.S. federal income tax purposes:

a citizen or resident of the United States;

a corporation, or other entity that is treated as a corporation for U.S. federal income tax purposes, created or organized in or under the laws of the United States, any state thereof, or the District of Columbia;

an estate, the income of which is subject to U.S. federal income taxation regardless of its source; or

a trust, if a court within the United States is able to exercise primary supervision over its administration and one or more U.S. persons have the authority to control all of the substantial decisions of such trust or has a valid election in effect under applicable U.S. Treasury Regulations to be treated as a United States person.


If a partnership (or any other entity treated as a partnership for U.S. federal income tax purposes) holds ordinary shares, the U.S. federal income tax consequences relating to an investment in our ordinary shares will depend in part upon the status of the partner and the activities of the partnership. Such a partner or partnership should consult its tax advisor regarding the U.S. federal income tax considerations of acquiring, owning and disposing of our ordinary shares in its particular circumstances.

As indicated below, this discussion is subject to U.S. federal income tax rules applicable to a “passive foreign investment company,” or a PFIC.

The following summary is of a general nature only and is not a substitute for careful tax planning and advice. Persons considering an investment in our ordinary shares should consult their own tax advisors as to the particular tax consequences applicable to them relating to the acquisition, ownership and disposition of our ordinary shares, including the applicability of U.S. federal, state and local tax laws and non-U.S. tax laws.

Distributions. Subject to the discussion under “Passive Foreign Investment Company Considerations,” below, the gross amount of any distribution actually or constructively received by a U.S. holder with respect to ordinary shares (other than certain distribution of shares to all shareholders) will be taxable to the U.S. holder as a dividend to the extent of our current and accumulated earnings and profits as determined under U.S. federal income tax principles. Distributions in excess of earnings and profits will be non-taxable to the U.S. holder to the extent of, and will be applied against and reduce, the U.S. holder’s adjusted tax basis in the ordinary shares. Distributions in excess of earnings and profits and such adjusted tax basis will generally be taxable to the U.S. holder as either long-term or short-term capital gain depending upon whether the U.S. holder has held our ordinary shares for more than one year as of the time such distribution is received. However, since we do not calculate our earnings and profits under U.S. federal income tax principles, it is expected that any distribution will be reported as a dividend, even if that distribution would otherwise be treated as a non-taxable return of capital or as capital gain under the rules described above. Non-corporate U.S. holders may qualify for the preferential rates of taxation with respect to dividends on ordinary shares applicable to long-term capital gains (i.e., gains from the sale of capital assets held for more than one year) applicable to qualified dividend income (as discussed below).

In general, the amount of a distribution paid to a U.S. holder in a currency other than the U.S. dollar, or foreign currency, will be the U.S. dollar value of the foreign currency calculated by reference to the spot exchange rate on the day the U.S. holder receives the distribution, regardless of whether the foreign currency is converted into U.S. dollars at that time. Any foreign currency gain or loss a U.S. holder realizes on a subsequent conversion of foreign currency into U.S. dollars will be U.S. source ordinary income or loss. If dividends received in a foreign currency are converted into U.S. dollars on the day they are received, a U.S. holder should not be required to recognize foreign currency gain or loss in respect of the dividend.

Sale, Exchange or Other Taxable Disposition of Our Ordinary Shares. Subject to the discussion below under “Passive Foreign Investment Company Considerations,” a U.S. holder will generally recognize gain or loss for U.S. federal income tax purposes upon the sale, exchange or other taxable disposition of ordinary shares in an amount equal to the difference between the U.S. dollar value of the amount realized from such sale or exchange

and the U.S. holder’s tax basis for those ordinary shares. Subject to the discussion under “Passive Foreign Investment Company Considerations” below, this gain or loss will generally be a capital gain or loss and will generally be treated as from sources within the United States. The adjusted tax basis in an ordinary share generally will be equal to the cost of such ordinary share. Capital gain from the sale, exchange or other taxable disposition of ordinary shares of a non-corporate U.S. holder is generally eligible for a preferential rate of taxation applicable to capital gains, if the non-corporate U.S. holder’s holding period determined at the time of such sale, exchange or other taxable disposition for such ordinary shares exceeds one year (i.e., such gain is long-term taxable gain). The deductibility of capital losses for U.S. federal income tax purposes is subject to limitations under the Code. Any such gain or loss that a U.S. holder recognizes generally will be treated as U.S. source income or loss for foreign tax credit limitation purposes.

Medicare Tax. Certain U.S. holders that are individuals, estates or trusts aremay be subject to a 3.8% tax on all or a portion of their “net investment income,” which may include all or a portion of their dividend income and net gains from the disposition of ordinary shares. Each U.S. holder that is an individual, estate or trust is urged to consult its tax advisors regarding the applicability of the Medicare tax to its income and gains in respect of its investment in our ordinary shares.

Passive Foreign Investment Company Considerations. If we are classified as a passive foreign investment company, or PFIC, in any taxable year, a U.S. holder would be subject to special rules generally intended to reduce or eliminate any benefits from the deferral of U.S. federal income tax that a U.S. holder could derive from investing in a non-U.S. company that does not distribute all of its earnings on a current basis.

A corporation organized outside the United States generally will be classified as a PFIC for U.S. federal income tax purposes in any taxable year in which, after applying certain look-through rules with respect to the income and assets of its subsidiaries, either: (i) at least 75% of its gross income is “passive income” or (ii) at least 50% of the average quarterly value of its total gross assets (which, assuming we are not a CFC for the year being tested,


(which, would be measured by fair market value of the assets, and for which purpose the total value of our assets may be determined in part by the market value of our ordinary shares, which is subject to change) is attributable to assets that produce “passive income” or are held for the production of “passive income.”

Passive income for this purpose generally includes dividends, interest, royalties, rents, gains from commodities and securities transactions and the excess of gains over losses from the disposition of assets which produce passive income, and also includes amounts derived by reason of the temporary investment of funds raised in offerings of our ordinary shares. If a non-U.S. corporation owns directly or indirectly at least 25% by value of the stock of another corporation, the non-U.S. corporation is treated for purposes of the PFIC tests as owning its proportionate share of the assets of the other corporation and as receiving directly its proportionate share of the other corporation’s income. If we are classified as a PFIC in any year with respect to which a U.S. holder owns our ordinary shares, we will continue to be treated as a PFIC with respect to such U.S. holder in all succeeding years during which the U.S. holder owns our ordinary shares, regardless of whether we continue to meet the tests described above, unless (i) we cease to be a PFIC and (ii) the U.S. holder makes a “deemed sale” election under PFIC rules.

We believe that we were not a PFIC during our 20152017 taxable year andended March 31, 2017and do not expect to be a PFIC during our 2016 taxable year.year ending March 31, 2018. Our status for any taxable year will depend on our assets and activities in each year, and because this is a factual determination made annually after the end of each taxable year, there can be no assurance that we will not be considered a PFIC for the current taxable year or any future taxable year. The market value of our assets may be determined in large part by reference to the market price of our ordinary shares, which is likely to fluctuate. In addition, the composition of our income and assets will be affected by how, and how quickly, we use the cash proceeds from our initial public offeringIPO and any subsequent offerings in our business. Further, even if we determine that we are not a PFIC after the close of our taxable year, there can be no assurances that the IRS will agree with our conclusion.

If we are a PFIC, then unless a U.S. holder makes one of the elections described below, a special tax regime will apply to both (a) any “excess distribution” by us to such U.S. holder (generally, the U.S. holder’s ratable portion of distributions in any year which are greater than 125% of the average annual distribution received by the U.S. holder in the shorter of the three preceding years or the U.S. holder’s holding period for our ordinary shares) and (b) any gain realized on the sale or other disposition of the ordinary shares. Under this regime, any excess distribution and realized gain will be treated as ordinary income and will be subject to tax as if (a) the excess distribution or gain had been realized ratably over the U.S. holder’s holding period, (b) the amount deemed realized in each year had been subject to tax in each year of that holding period at the highest marginal rate for such year (other than income allocated to the current period or any taxable period before we became a PFIC, which would be subject to tax at the U.S. holder’s regular ordinary income rate for the current year and would not be subject to the interest charge discussed below), and (c) the interest charge generally applicable to underpayments of tax had been imposed on the taxes deemed to have been payable in those years. In addition, dividend distributions made to the U.S. holder will not qualify for the lower rates of taxation applicable to long-term capital gains discussed above under “Distributions.”

Certain elections exist that may alleviate some of the adverse consequences of PFIC status and would result in an alternative treatment (such as mark-to-market treatment) of our ordinary shares. If a U.S. holder makes the mark-to-market election, the U.S. holder generally will recognize as ordinary income any excess of the fair market value of the ordinary shares at the end of each taxable year over their adjusted tax basis, and will recognize an ordinary loss in respect of any excess of the adjusted tax basis of the ordinary shares over their fair market value at the end of the taxable year (but only to the extent of the net amount of income previously included as a result of the mark-to-market election). If a U.S. holder makes the election, the U.S. holder’s tax basis in the ordinary shares will be adjusted to reflect these income or loss amounts. Any gain recognized on the sale or other disposition of ordinary shares in a year when we are a PFIC will be treated as ordinary income and any loss will be treated as an ordinary loss (but only to the extent of the net amount of income previously included as a result of the mark-to-market election). The mark-to-market election is available only if we are a PFIC and our ordinary shares are “regularly traded” on a “qualified exchange.” Our ordinary shares will be treated as “regularly traded” in any calendar year in which more than a de minimis quantity of the ordinary shares are traded on a qualified exchange on at least 15 days during each calendar quarter (subject to the rule that trades that have as one of their principle purposes the meeting of the trading requirement are disregarded). The NASDAQ Global Select Market is a qualified exchange for this purpose and, consequently, if the ordinary shares are regularly traded, the mark-to-market election will be available to a U.S. holder.

We do not currently intend to provide the information necessary for U.S. holders to make qualified electing fund elections if we were treated as a PFIC for any taxable year. U.S. holders should consult their tax advisors to determine whether any of these elections would be available and if so, what the consequences of the alternative treatments would be in their particular circumstances.

If we are determined to be a PFIC, the general tax treatment for U.S. holders described in this section would apply to indirect distributions and gains deemed to be realized by U.S. holders in respect of any of our subsidiaries that also may be determined to be PFICs.


If a U.S. holder owns ordinary shares during any taxable year in which we are a PFIC and the U.S. holder recognizes gain on a disposition of our ordinary shares, receives distributions with respect to our ordinary shares, or has made a mark-to-market election with respect to our ordinary shares the U.S. holder generally will be required to file an IRS Form 8621 (Information Return by a Shareholder of a Passive Foreign Investment Company or Qualified Electing Fund) with respect to the company, generally with the U.S. holder’s federal income tax return for that year. In addition, in general, a U.S. person who is shareholder of a PFIC is required to file an IRSa Form 8621 annually to report information regarding such person’s PFIC shares if on the last day of the shareholder’s taxable year the aggregate value of all stock owned directly or indirectly by the shareholder exceeds $25,000 ($50,000 for joint filers), or for stock owned indirectly through another PFIC exceeds $5,000. If a U.S. person holds an interest in

a domestic partnership (or a domestic entity or arrangement treated as a partnership for U.S. federal income tax purposes) or an S corporation that owns interest in a PFIC, as long as the partnership or S corporation itself has filed the form and has made a qualified electing fund or mark-to-market election, the members of the partnership aren’t required to file the IRS Form 8621. If our companyit is determined that we were a PFIC for a given taxable year, then U.S. holders should consult their tax advisor concerning their annual filing requirements.

The U.S. federal income tax rules relating to PFICs are complex. Prospective U.S. holders are urged to consult their own tax advisers with respect to the acquisition, ownership and disposition of our ordinary shares, the consequences to them of an investment in a PFIC, any elections available with respect to our ordinary shares and the IRS information reporting obligations with respect to the acquisition, ownership and disposition of our ordinary share.

Backup Withholding and Information Reporting. U.S. holders generally will be subject to information reporting requirements with respect to dividends on ordinary shares and on the proceeds from the sale, exchange or disposition of ordinary shares that are paid within the United States or through U.S.-related financial intermediaries, unless the U.S. holder is an “exempt recipient.” In addition, U.S. holders may be subject to backup withholding on such payments, unless the U.S. holder provides a taxpayer identification number and a duly executed IRS Form W-9 or otherwise establishes an exemption. Backup withholding is not an additional tax, and the amount of any backup withholding will be allowed as a credit against a U.S. holder’s U.S. federal income tax liability and may entitle such holder to a refund, provided that the required information is timely furnished to the IRS.

Certain Reporting Requirements With Respect to Payments of Offer Price. U.S. holders paying more than $100,000 for our ordinary shares generally may be required to file IRS Form 926 reporting the payment of the offer price for our ordinary shares to us. Substantial penalties may be imposed upon a U.S. holder that fails to comply. Each U.S. holder should consult its own tax advisor as to the possible obligation to file IRS Form 926.

Foreign Asset Reporting. Certain U.S. holders who are individuals are required to report information relating to an interest in our ordinary shares, subject to certain exceptions (including an exception for shares held in accounts maintained by U.S. financial institutions) by filing IRS Form 8938 (Statement of Specified Foreign Financial Assets) with their U.S. federal income tax return. An asset with respect to which an IRS Form 8621 has been filed does not have to be reported on IRS Form 8938, however, U.S. holders are urged to consult their tax advisors regarding their information reporting obligations, if any, with respect to their ownership and disposition of our ordinary shares.

THE DISCUSSION ABOVE IS A GENERAL SUMMARY. IT DOES NOT COVER ALL TAX MATTERS THAT MAY BE OF IMPORTANCE TO A PROSPECTIVE INVESTOR. EACH PROSPECTIVE INVESTOR IS URGED TO CONSULT ITS OWN TAX ADVISOR ABOUT THE TAX CONSEQUENCES TO IT OF AN INVESTMENT IN ORDINARY SHARES IN LIGHT OF THE INVESTOR’S OWN CIRCUMSTANCES.

ITEM 11. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market risk represents the risk of loss that may impact our financial position due to adverse changes in financial market prices and rates. Our market risk exposure is primarily a result of fluctuations in foreign currency rates, although we also have some exposure due to potential changes in inflation or interest rates. We do not hold financial instruments for trading purposes.

Foreign Currency Riskcurrency risk

Our results of operations and cash flows are subject to fluctuations due to changes in foreign currency exchange rates, particularly changes in the British pound and South African rand. Percentage of revenues and expenses in foreign currency is as follows:

As of March 31, 20162017 and 2015,2016, we had $20.9$24.0 million and $16.5$20.9 million respectively, of receivables denominated in currencies other than the U.S. dollar. We also maintain cash accounts denominated in currencies other than the local currency, which exposes us to foreign exchange rate movements. As of March 31, 20162017 and 2015,2016, we had $17.6$27.0 million and $17.1$17.6 million respectively, of cash denominated in currencies other than the U.S. dollar. As of March 31, 2017, cash denominated in British pounds and South African rand was $19.6 million and $5.0 million, respectively. As of March 31, 2016, cash denominated in British pounds and South African rand was $14.0 million and $2.1 million, respectively. As of March 31, 2015, cash denominated in British pounds and South African rand was $13.7 million and $2.4 million, respectively.

In addition, although our foreign subsidiaries have intercompany accounts that are eliminated upon consolidation, these accounts expose us to foreign currency exchange rate fluctuations. Exchange rate fluctuations on short-term intercompany accounts are recorded in our consolidated statements of operations under “foreign exchange (expense) income.”


Currently, our largest foreign currency exposures are to the British pound and South African rand. Relative to foreign currency exposures existing atas of March 31, 2016,2017, significant movements in foreign currency exchange rates wouldmay expose us to significant losses in earnings or cash flows or significantly diminish the fair value of our foreign currency financial instruments. For the year ended March 31, 2017, we estimate that a 10% decrease in foreign currency exchange rates against the U.S. dollar would have decreased revenue by $9.3 million, decreased expenses by $9.3 million and have no impact on our operating results. For the year ended March 31, 2016, we estimate that a 10% decrease in foreign currency exchange rates against the U.S. dollar would have decreased revenue by $7.9 million, decreased expenses by $8.0 million and increased operating income by $0.1 million. For the year ended March 31, 2015, we estimate that a 10% decrease in foreign currency exchange rates against the U.S. dollar would have decreased revenues by $7.1 million, decreased expenses by $7.5 million and increased operating income by $0.4 million. For the year ended March 31, 2014, we estimate that a 10% decrease in foreign currency exchange rates against the U.S. dollar would have decreased revenues by $5.7 million, decreased expenses by $6.0 million and increased operating income by $0.3 million. The estimates used assume that all currencies move in the same direction at the same time and the ratio of non-U.S. dollar denominated revenue and expenses to U.S. dollar denominated revenue and expenses does not change from current levels. Since a portion of our revenue is deferred revenue that is recorded at different foreign currency exchange rates, the impact to revenue of a change in foreign currency exchange rates is recognized over time, and the impact to expenses is more immediate, as expenses are recognized at the current foreign currency exchange rate in effect at the time the expense is incurred. All of the potential changes noted above are based on sensitivity analyses performed on our financial results as of March 31, 2016, 20152017 and 2014.2016.

Inflation Riskrisk

Inflationary factors, such as increases in our operating expenses, may adversely affect our results of operations, as our customers typically purchase services from us on a subscription basis over a period of time. Although we do not believe that inflation has had a material impact on our financial position or results of operations to date, an increase in the rate of inflation in the future may have an adverse effect on our levels of operating expenses as a percentage of revenue if we are unable to increase the prices for our subscription-based services to keep pace with these increased expenses.

Interest Rate Riskrate risk

We are exposed to market risk related to changes in interest rates. Our investments primarily consist of short-term investments and money market funds. As of March 31, 20162017 and 2015,2016, we had cash, and cash equivalents and investments of $106.1$111.7 million and

$32.9 $106.1 million, respectively. The carrying amount of our cash equivalents reasonably approximates fair value, due to the short maturities of these investments. The primary objectives of our investment activities are the preservation of capital, the fulfillment of liquidity needs and the fiduciary control of cash and investments. We do not enter into investments for trading or speculative purposes. Our investments are exposed to market risk due to a fluctuation in interest rates, which may affect our interest income and the fair market value of our investments. Due to the short-term nature of our investment portfolio, we believe only dramatic fluctuations in interest rates would have a material effect on our investments. We do not believe that an immediate 10% increase in interest rates would have a material effect on the fair market value of our portfolio. As such we do not expect our operating results or cash flows to be materially affected by a sudden change in market interest rates.

As of March 31, 20162017 and 2015,2016, we had an outstanding balance of $6.9$1.7 million and $12.4$6.9 million, respectively, aggregate principal amount on our term loans, which have a fixed interest rate of 4.5%. Since these instruments bear interest at fixed rates, we have no financial statement risk associated with changes in interest rates. However, the fair value of these instruments fluctuates as interest rate changes.

E. Use of Proceedsproceeds

On November 24, 2015, we closed the sale of 7,750,000 ordinary shares to the public at an initial public offering price of $10.00 per share. The offer and sale of the shares in the IPO was registered under the Securities Act pursuant to registration statements on Form F-1 (File No. 333-207454), which was filed with the SEC on October 16, 2015, and amended subsequently and declared effective on November 18, 2015. Following the sale of the shares in connection with the closing of our IPO, the offering terminated. The offering did not terminate before any of the securities registered in the registration statements were sold. Goldman, Sachs & Co. acted as lead book-running manager, Barclays Capital Inc., Jeffries LLC and RBC Capital Markets, LLC acted as book-running managers, and Oppenheimer & Co. Inc. acted as co-manager for the offering.

We raised approximately $68.3 million in net proceeds, after deducting underwriting discounts and commissions of approximately $5.4 million and other offering expenses of approximately $3.8 million. No offering expenses were paid directly or indirectly to any of our directors or officers or their associates or persons owning ten percent or more of any class of our equity securities or to any other affiliates. As of March 31, 2016,2017, we have not used any of the net offering proceeds.

Management's Annual Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Rule 13a-15(f) under the Exchange Act. Under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, we conducted an assessment of the effectiveness of our internal control over financial reporting based on the framework and criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission as of the end of the period covered by this Annual Report on Form 20-F. Based on that assessment, our management has concluded that as of March 31, 2017, our internal control over financial reporting was effective.

The Audit Committee has adopted policies and procedures relating to the approval of all audit and non-audit services that are to be performed by our independent registered public accounting firm. These policies generally provide that we will not engage our independent registered public accounting firm to render audit or non-audit services unless the service is specifically approved in advance by the Audit Committee or the engagement is entered into pursuant to the pre-approval procedure described below.


The audit committee pre-approves all auditing services and the terms of non-audit services, but only to the extent that the non-audit services are not prohibited under applicable law and the committee determines that the non-audit services do not impair the independence of the independent registered public accounting firm. In situations where it is impractical to wait until the next regularly scheduled quarterly meeting, the chairman of the audit committee has been delegated authority to approve audit and non-audit services. The chairman is required to report any approvals to the full committee at its next scheduled meeting.

From time to time, the Audit Committee may pre-approve specified types of services that are expected to be provided to us by our independent registered public accounting firm during the next 12 months. Any such pre-approval is detailed as to the particular service or type of services to be provided and is also generally subject to a maximum dollar amount. Any proposed services exceeding pre-approved amounts will also require separate pre-approval by the Audit Committee. In fiscal 20162017 and 2015,2016, our Audit Committee approved all of the services provided by Ernst & Young.Young LLP.

INDEX TO CONSOLIDATED FINANCIAL STATEMENTS

 


REPORT OF INDEPENDENT REGISTEREDREGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Shareholders of

Mimecast Limited

We have audited the accompanying consolidated balance sheets of Mimecast Limited (the Company) as of March 31, 20162017 and 2015,2016, and the related consolidated statements of operations, comprehensive loss, convertible preferred shares and shareholders’ equity (deficit) and cash flows for each of the three years in the period ended March 31, 2016.2017. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. We were not engaged to perform an audit of the Company’s internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of Mimecast Limited at March 31, 20162017 and 2015,2016, and the consolidated results of its operations and its cash flows for each of the three years in the period ended March 31, 2016,2017, in conformity with U.S. generally accepted accounting principles.

MIMECAST LIMITED

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Years ended March 31, 2017, 2016 2015 and 20142015

(in thousands, except share and per share data, unless otherwise noted)

1. Organization and Description of Business

Mimecast Limited (Mimecast Jersey) is a public limited company organized under the laws of the Bailiwick of Jersey on July 28, 2015. On November 4, 2015, Mimecast Jersey changed its corporate structure whereby it became the holding company of Mimecast Limited (Mimecast UK), a private limited company incorporated in 2003 under the laws of England and Wales, and its wholly-owned subsidiaries by way of a share-for-share exchange in which the shareholders of Mimecast UK exchanged their shares in Mimecast UK for an identical number of shares of the same class in Mimecast Jersey. Upon the exchange, the historical consolidated financial statements of Mimecast UK became the historical consolidated financial statements of Mimecast Jersey.

Mimecast Jersey and its subsidiaries (together the Group, the Company, Mimecast or we) is headquartered in London, England. The principal activity of the Group is the provision of email management services. Mimecast delivers a software-as-a-service (SaaS) enterprise email management service for archiving, continuity, and security. By unifying disparate and fragmented email environments into one holistic solution from the cloud, Mimecast minimizes risk and reduces cost and complexity while providing total end-to-end control of email. Mimecast’s proprietary software platform provides a single system to address key email management issues. Mimecast operates principally in Europe, North America, Africa and Australia.

The Company is subject to a number of risks and uncertainties common to companies in similar industries and stages of development including, but not limited to, rapid technological changes, competition from substitute products and services from larger companies, customer concentration, management of international activities, protection of proprietary rights, patent litigation, and dependence on key individuals.

2. Summary of Significant Accounting Policies

The accompanying consolidated financial statements reflect the application of certain significant accounting policies as described below and elsewhere in these notes to the consolidated financial statements. The Company believes that a significant accounting policy is one that is both important to the portrayal of the Company’s financial condition and results, and requires management’s most difficult, subjective, or complex judgments, often as the result of the need to make estimates about the effect of matters that are inherently uncertain.

Basis of Presentation

The accompanying consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (GAAP). Any reference in these notes to applicable guidance is meant to refer to the authoritative United States generally accepted accounting principles as found in the Accounting Standards Codification (ASC) and Accounting Standards Update (ASU) of the Financial Accounting Standards Board (FASB).

Goodwill in the amount of $0.3 million was included in other assets as of March 31, 2016 and has been reclassified to goodwill in this Annual Report on Form 20-F to conform to current period presentation.  This had no impact on previously reported results of operations or cash flows.

Principles of Consolidation

The consolidated financial statements include the accounts of the Company and its subsidiaries. All intercompany transactions and balances have been eliminated in consolidation.

Share Consolidation

On November 3, 2015, a committee of the Company’s Board of Directors (the Board) approved a 1-for-6 share consolidation of the Company’s shares. The share consolidation was approved by our shareholders on November 5, 2015 and became effective on November 5, 2015. All share and per share data shown in the accompanying consolidated financial statements and related notes have been retroactively revised to reflect the reverse stock split.


Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of income and expenses during the reporting period.

Significant estimates relied upon in preparing these consolidated financial statements include revenue recognition, allowances for doubtful accounts, intangible asset valuations, amortization periods, expected future cash flows used to evaluate the recoverability of long-lived assets, contingent liabilities, expensing and capitalization of research and development costs for internal-use software, the determination of the fair value of share-based awards issued, share-based compensation expense, and the recoverability of the Company’s net deferred tax assets and related valuation allowance.

Although the Company regularly assesses these estimates, actual results could differ materially from these estimates. Changes in estimates are recorded in the period in which they become known. The Company bases its estimates on historical experience and various other assumptions that it believes to be reasonable under the circumstances. Actual results may differ from management’s estimates if these results differ from historical experience, or other assumptions do not turn out to be substantially accurate, even if such assumptions are reasonable when made. Changes in estimates are recorded in the period in which they become known.

Subsequent Events Considerations

The Company considers events or transactions that occur after the balance sheet date but prior to the issuance of the financial statements to provide additional evidence for certain estimates or to identify matters that require additional disclosure. Subsequent events have been evaluated as required. See Note 13.15.

Cash, and Cash Equivalents and Investments

The Company considers all highly liquid instruments purchased with an original maturity date of 90 days or less from the date of purchase to be cash equivalents. ManagementCash and cash equivalents consist of cash on deposit with banks, amounts held in interest-bearing money market funds and investments with maturities of 90 days or less from the date of purchase. Cash equivalents are carried at cost, which approximates their fair market value. Investments not classified as cash equivalents are presented as either short-term or long-term investments based on both their stated maturities as well as the time period the Company intends to hold such securities. The Company determines the appropriate classification of investments at the time of purchase and re-evaluatesreevaluates such determinationdesignation at each balance sheet date. The Company adjusts the cost of investments for amortization of premiums and accretion of discounts to maturity. The Company includes such amortization and accretion in interest income.

CashThe Company has classified all of its investments as of March 31, 2017 as available-for-sale pursuant to ASC 320, Investments – Debt and Equity Securities. The Company records available-for-sale securities at fair value, with unrealized gains and losses included in accumulated other comprehensive loss in shareholders’ equity. The Company includes interest and dividends on securities classified as available-for-sale in interest income. Realized gains and losses are recorded in the consolidated statements of operations and comprehensive loss based on the specific-identification method. There were no realized gains or losses on investments for the year ended March 31, 2017.

The Company reviews investments for other-than-temporary impairment whenever the fair value of an investment is less than the amortized cost and evidence indicates that an investment’s carrying amount is not recoverable within a reasonable period of time. Other-than-temporary impairments of investments are recognized in the consolidated statements of operations if the Company has experienced a credit loss, has the intent to sell the investment, or if it is more likely than not that the Company will be required to sell the investment before recovery of the amortized cost basis. Evidence considered in this assessment includes reasons for the impairment, compliance with the Company’s investment policy, the severity and the duration of the impairment and changes in value subsequent to the end of the period. The aggregate fair value of investments held by the Company in an unrealized loss position for less than twelve months as of March 31, 2017 was $47.8 million. As of March 31, 2017, the Company determined that no other-than-temporary impairments were required to be recognized in the consolidated statements of operations.


The following is a summary of cash, cash equivalents consistand investments as of cash on deposit with banksMarch 31, 2017 and amounts held in interest-bearing money market funds. Cash equivalents are carried at cost, which approximates their fair market value.March 31, 2016:

Revenue Recognition

The Company derives its revenue from two sources: (1) subscription revenues,revenue, which areis comprised of subscription fees from customers accessing the Company’s cloud services and from customers purchasing additional support beyond the standard support that is included in the basic subscription fees; and (2) related professional services and other revenue, which consists primarily of set-up and ingestion fees as well as training fees.

The Company recognizes revenue when all of the following conditions are satisfied:

there is persuasive evidence of an arrangement;

the service has been or is being provided to the customer;

the collection of the fees is probable; and

the amount of fees to be paid by the customer is fixed or determinable.

The Company’s subscription arrangements provide customers the right to access its hosted software applications. Customers do not have the right to take possession of the Company’s software during the hosting arrangement. Accordingly, the Company recognizes revenue in accordance with ASC 605,Revenue Recognition, and Staff Accounting Bulletin (SAB) No. 104,Revenue Recognition.

The Company’s products and services are sold directly by the Company’s sales force and also indirectly by third-party resellers. In accordance with the provisions of ASC 605, the Company has considered certain factors in determining whether the end-user or the third-party reseller is the Company’s customer in arrangements involving resellers. The Company has concluded that in the majority of transactions with resellers, the reseller is the Company’s customer. In these arrangements, the Company considered that it is the reseller, and not the Company, that has the relationship with the end-user. Specifically, the reseller has the ability to set pricing with the end-user and the credit risk with the end-user is borne by the reseller. Further, the reseller is not obligated to report its transaction price with the end-user to the Company, and in the majority of transactions, the Company is unable to determine the amount paid by the end-user customer to the reseller in these transactions. As a result of such considerations, revenue for these transactions is presented in the accompanying consolidated statements of operations based upon the amount billed to the reseller. For transactions where the Company has determined that the end-user is the ultimate customer, revenue is presented in the accompanying consolidated statements of operations based on the transaction price with the end-user.

Subscription and support revenue is recognized ratably over the term of the contract, typically one year in duration, beginning on the commencement date of each contract.

Amounts that have been invoiced are recorded in accounts receivable and in deferred revenue or revenue, depending on whether the revenue recognition criteria have been met.


The Company’s professional services contracts are on a time and material basis. When these services are not combined with subscription revenues as a single unit of accounting, as discussed below, these revenues are recognized as the services are rendered.

Revenue is presented net of any taxes collected from customers.

At times, the Company may enter into arrangements with multiple-deliverables that generally include multiple subscriptions, premium support and professional services. For arrangements with multiple deliverables, the Company evaluates each deliverable to determine whether it represents a separate unit of accounting based on the following criteria: (a) whether the delivered item has value to the customer on a stand-alone basis; and (b) if the contract includes a general right of return relative to the delivered item, whether delivery or performance of the undelivered items is considered probable and substantially within our control.

If the deliverables are determined to qualify as separate units of accounting, consideration is allocated to each unit of accounting based on the units’ relative selling prices. The Company determines the relative selling price for a deliverable based on its vendor-specific objective evidence of fair value (VSOE), if available, or its best estimate of selling price (BESP), if VSOE is not available. The Company has determined that third-party evidence of selling price (TPE) is not a practical alternative due to differences in its service offerings compared to other parties and the availability of relevant third-party pricing information. The amount of revenue allocated to delivered items is limited by contingent revenue, if any.

Subscription services have standalone value as such services are often sold separately. In determining whether professional services sold together with the subscription services have standalone value, the Company considers the following factors for each professional services agreement: availability of the services from other vendors, the nature of the professional services, the determination that customers cannot resell the services that Mimecast provides, the timing of when the professional services contract was signed in comparison to the subscription service start date and the contractual dependence of the subscription service on the customer’s satisfaction with the professional services work. Professional services sold at the time of the multiple-element subscription arrangement typically include customer set-up and ingestion services. To date, the Company has concluded that all of these professional services included in executed multiple-deliverable arrangements do not have standalone value and are therefore not considered separate units of accounting. These professional services are purchased by customers only in contemplation of, or in concert with, purchasing one of the hosted subscription solutions and, therefore, are not considered a substantive service, such that the provision of such

service does not reflect the culmination of the earnings process. Mimecast does not sell these services without the related underlying primary subscription as there would be no practical interest or need on the behalf of a customer to buy these services without the underlying subscription. The Company does not have any knowledge of other vendors selling these services on a stand-alone basis and there is no way for an end-user to resell the deliverable. Accordingly, the deliverables within the arrangement including both subscription services and other professional services are accounted for as a single unit of accounting in accordance with the guidance in SAB No. 104. On these occasions, revenue for the professional services deliverables in the arrangement is recognized on a straight-line basis over the contractual term or the average customer life, as further described below.

Deferred Revenue

Deferred revenue primarily consists of billings or payments received in advance of revenue recognition from subscription services described above and is recognized as the revenue recognition criteria are met. In addition, deferred revenue consists of amounts paid by customers related to upfront set-up or ingestion fees. Revenue related to such services is recognized over the contractual term or the average customer life, whichever is longer. The estimated customer life has been determined to be five years.

Deferred revenue that is expected to be recognized during the succeeding twelve month period is recorded as current deferred revenue and the remaining portion is recorded as noncurrent in the accompanying consolidated balance sheets.

Cost of Revenue

Cost of revenue primarily consists of expenses related to supporting and hosting the Company’s product offerings and delivering professional services. These costs include salaries, benefits, incentive compensation and share-based compensation expense related to the management of the Company’s data centers, customer support team and the Company’s professional services team, in addition to third-party service provider costs such as data center and networking expenses, allocated overhead and depreciation expense.


Concentration of Credit Risk and Off-Balance Sheet Risk

The Company has no off-balance sheet risk, such as foreign exchange contracts, option contracts, or other foreign hedging arrangements. Financial instruments, which potentially subject us to concentrations of credit risk, consist primarily of cash and cash equivalents, investments and accounts receivable. We maintain our cash and cash equivalents with major financial institutions of high-credit quality. Although the Company deposits its cash with multiple financial institutions, its deposits, at times, may exceed federally insured limits.

Credit risk with respect to accounts receivable is dispersed due to our large number of customers. The Company’s accounts receivable are derived from revenue earned from customers primarily located in the United Kingdom, the United States, and South Africa. The Company generally does not require its customers to provide collateral or other security to support accounts receivable. Credit losses historically have not been significant and the Company generally has not experienced any material losses related to receivables from individual customers, or groups of customers. Due to these factors, no additional credit risk beyond amounts provided for collection losses is believed by management to be probable in the Company’s accounts receivable. As of March 31, 20162017 and 2015,2016, no individual customer represented more than 10% of our accounts receivable. During the years ended March 31, 2017, 2016 2015 and 2014,2015, no individual customer represented more than 10% of our revenue.

The Company's Board approved investment policy permits investments in fixed income securities denominated and payable in U.S. dollars including U.S. government and agency securities, non-U.S. government securities, money market instruments, commercial paper, certificates of deposit, corporate bonds and asset-backed securities. The Company diversifies its investment portfolio by investing in multiple types of investment-grade securities across various industries and issuers, limiting the amount invested in individual securities and limiting the average maturity to two years or less.

As of March 31, 2017, our investments consisted primarily of investment-grade fixed income corporate debt securities with maturities ranging from 1 to 10 months, non-U.S. government securities with maturities ranging from 5 to 12 months and U.S. treasury securities with maturities in less than a month.

Allowance for Doubtful Accounts

We make judgments as to our ability to collect outstanding receivables and provide allowances for the portion of receivables when a loss is reasonably expected to occur. The allowance for doubtful accounts is established to represent the best estimate of the net realizable value of the outstanding accounts receivable. The

development of the allowance for doubtful accounts is based on a review of past due amounts, historical write-off and recovery experience, as well as aging trends affecting specific accounts and general operational factors affecting all amounts. In addition, factors are developed utilizing historical trends in bad debts, returns and allowances.

We consider current economic trends when evaluating the adequacy of the allowance for doubtful accounts. If circumstances relating to specific customers change or unanticipated changes occur in the general business environment, our estimates of the recoverability of receivables could be further adjusted. For the years ended March 31, 2017, 2016 2015 and 2014,2015, bad debt expense was $87, $91 $133 and $23,$133, respectively. The allowance for doubtful accounts as of March 31, 20162017 and 20152016 was not material.

Property and Equipment

Property and equipment are stated at cost, and are depreciated using the straight-line method over the estimated useful life of the assets. Leasehold improvements are amortized over the shorter of the lease term or the estimated useful life of the related asset. Property and equipment acquired under capital leases is amortized over the lease term or, in circumstances where ownership is transferred by the end of the lease or there is a bargain purchase option, over the useful life that would be assigned if the asset were owned. Upon retirement or sale, the cost of assets disposed of, and the related accumulated depreciation, are removed from the accounts, and any resulting gain or loss is included in the determination of net (loss) income in the period of retirement or sale. The estimated useful lives of the Company’s property and equipment are as follows:

 

Estimated

Computer equipment

3 to 5

Expenditures for maintenance and repairs are charged to expense as incurred, whereas major betterments are capitalized as additions to property and equipment. The Company reviews its property

Business Combinations

In accordance with ASC 805, Business Combinations (ASC 805), we recognize the tangible and equipmentintangible assets acquired and liabilities assumed based on their estimated fair values. Determining these fair values requires management to make significant estimates and assumptions, especially with respect to intangible assets.

We recognize identifiable assets acquired and liabilities assumed at their acquisition date fair value. Goodwill as of the acquisition date is measured as the excess of consideration transferred over the net of the acquisition date fair value of the assets acquired and the liabilities assumed and represents the expected future economic benefits arising from other assets acquired that are not individually identified and separately recognized. While we use our best estimates and assumptions as part of the purchase price allocation process to accurately value assets acquired and liabilities assumed at the acquisition date, our estimates are inherently uncertain and subject to refinement. Assumptions may be incomplete or inaccurate, and unanticipated events or circumstances may occur, which may affect the accuracy or validity of such assumptions, estimates or actual results. As a result, during the measurement period, which may be up to one year from the acquisition date, we record adjustments to the assets acquired and liabilities assumed with the corresponding offset to goodwill to the extent that we identify adjustments to the preliminary purchase price allocation. Upon the conclusion of the measurement period or final determination of the values of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to the consolidated statements of operations.

Goodwill and acquired intangible assets

Goodwill is not amortized, but is evaluated for impairment annually, or whenever events or changes in circumstances indicate that the carrying value of certain assets mightmay not be recoverable. In these instances,We have determined that there is a single reporting unit for the Company recognizes anpurpose of conducting this goodwill impairment loss when it is probable thatassessment. For purposes of assessing potential impairment, we estimate the estimated cash flows are less thanfair value of the reporting unit, based on our market capitalization, and compare this amount to the carrying value of the asset.reporting unit. If we determine that the carrying value of the reporting unit exceeds its fair value, an impairment charge would be required. Our annual goodwill impairment test is performed as of January 1st of each year. To date, we have not identified any impairment to goodwill.

Intangible assets acquired in a business combination are recorded at their estimated fair values at the date of acquisition. We amortize acquired definite-lived intangible assets over their estimated useful lives based on the pattern of consumption of the economic benefits or, if that pattern cannot be readily determined, on a straight-line basis.

Impairment of Long-Lived Assets

The Company reviews long-lived assets, such asincluding property and equipment and definite-lived intangible assets, for impairment whenever events or changes in circumstances indicate that the carrying value of an asset may not be recoverable. During this review, the Company re-evaluates the significant assumptions used in determining the original cost and estimated lives of long-lived assets. Although the assumptions may vary from asset to asset, they generally include operating results, changes in the use of the asset, cash flows, and other indicators of value. Management then determines whether the remaining useful life continues to be appropriate, or whether there has been an impairment of long-lived assets based primarily upon whether expected future undiscounted cash flows are sufficient to support the assets’ recovery.recoverability of these assets. Recoverability of these assets is measured by comparison of the carrying amount of the asset to the future undiscounted cash flows the asset is expected to generate. If the asset is considered to be impaired, the amount of any impairment is measured as the difference between the carrying value and the fair value of the impaired asset.

For the years ended March 31, 2017, 2016 2015 and 2014,2015, the Company did not identify any impairment of its long-lived assets.

Disclosure of Fair Value of Financial Instruments

The carrying amounts of the Company’s financial instruments, which include cash and cash equivalents, accounts receivable, accounts payable, accrued expenses and borrowings under the Company’s long-term debt

arrangements, approximated their fair values at March 31, 2016 and 2015 due to the short-term nature of these instruments, and for the long-term debt, the interest rates the Company believes it could obtain for borrowings with similar terms.

The Company has evaluated the estimated fair value of financial instruments using available market information. The use of different market assumptions and/or estimation methodologies could have a significant effect on the estimated fair value amounts. See below for further discussion.

Fair Value Measurements

ASC 820,Fair Value Measurements and Disclosures, establishes a three-level valuation hierarchy for instruments measured at fair value that distinguishes between assumptions based on market data (observable inputs) and the Company’s own assumptions (unobservable inputs). Observable inputs are inputs that market participants would use in pricing the asset or liability based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company’s assumptions about the inputs that market participants would use in pricing the asset or liability, and are developed based on the best information available in the circumstances.

ASC 820 identifies fair value as the exchange price, or exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants based on the highest and best use of the asset or


liability. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. The Company uses valuation techniques to measure fair value that maximize the use of observable inputs and minimize the use of unobservable inputs. These inputs are prioritized as follows:

Level 1 inputs—Unadjusted observable quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date.

Level 2 inputs—Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly.

Level 3 inputs—Unobservable inputs for determining the fair values of assets or liabilities that reflect an entity’s own assumptions about the assumptions that market participants would use in pricing the assets or liabilities.

To the extent that the valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised by the Company in determining fair value is greatest for instruments categorized in Level 3. A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement.

The Company evaluates assets and liabilities subject to fair value measurements on a recurring and nonrecurring basis to determine the appropriate level to classify them for each reporting period.

Cash equivalents include money market funds with original maturities of 90 days or less from the date of purchase. The fair value measurement of these assets is based on quoted market prices in active markets for identical assets and, therefore, these assets are recorded at fair value on a recurring basis and classified as Level 1 in the fair value hierarchy for all periods presented. As of March 31, 2016 and 2015, cash equivalents held in money market funds totaled $10.7 million and $10.9 million, respectively.

As of March 31, 2016 and 2015, we did not have any assets or liabilities measured at fair value on a recurring basis using significant other observable inputs (Level 2) or on a recurring basis using significant unobservable inputs (Level 3).

The Company measures eligible assets and liabilities at fair value, with changes in value recognized in earnings. Fair value treatment may be elected either upon initial recognition of an eligible asset or liability or, for an existing asset or liability, if an event triggers a new basis of accounting. The Company did not elect to remeasure any of its existing financial assets or liabilities, and did not elect the fair value option for any financial assets and liabilities transacted in the years ended March 31, 2017, 2016 2015 and 2014.2015.

Software Development Costs

Costs incurred to develop software applications used in the Company’s SaaS platform consist of certain direct costs of materials and services incurred in developing or obtaining internal-use computer software, and payroll and payroll-related costs for employees who are directly associated with, and who devote time to, the project. These costs generally consist of internal labor during configuration, coding, and testing activities. Research and development costs incurred during the preliminary project stage or costs incurred for data conversion activities, training, maintenance and general and administrative or overhead costs are expensed as incurred. Once an application has reached the development stage, internal and external costs, if direct and incremental, are capitalized until the application is substantially complete and ready for its intended use. Qualified costs incurred during the operating stage of the Company’s software applications relating to upgrades and enhancements are capitalized to the extent it is probable that they will result in added functionality, while costs incurred for maintenance of, and minor upgrades and enhancements to, internal-use software are expensed as incurred. During the years ended March 31, 2017, 2016 2015 and 2014,2015, the Company believes the substantial majority of its development efforts were either in the preliminary project stage of development or in the operation stage (post-implementation), and accordingly, no costs have been capitalized during these periods. These costs are included in the accompanying consolidated statements of operations as research and development expense.

Foreign Currency Translation

The reporting currency of the Company is the U.S. dollar. We determine the functional currency for our foreign subsidiaries by reviewing the currencies in which its respective operating activities occur. The functional currency of the Company’s foreign subsidiaries is the local currency of each subsidiary. All assets and liabilities in the balance sheets of entities whose functional currency is a currency other than the U.S. dollar are translated into U.S. dollar equivalents at exchange rates as follows: (i) asset and liability accounts at period-end rates, (ii) income statement accounts at weighted-average exchange rates for the period, and (iii) shareholders’ equity accounts at historical exchange rates. Foreign exchange transaction gains and losses are included in foreign exchange (expense) income in the accompanying consolidated statements of operations. The effects of foreign currency translation adjustments are included as a component of accumulated other comprehensive (loss) incomeloss in the accompanying consolidated balance sheets.

Net (Loss) Income Per Share

Net (loss) income per share information is determined using the two-class method, which includes the weighted-average number of ordinary shares outstanding during the period and other securities that participate in dividends (a participating security). The Company considers theconsidered its convertible preferred shares to be participating securities because they includeincluded rights to participate in dividends with the ordinary shares.


Under the two-class method, basic net (loss) income per share attributable to ordinary shareholders is computed by dividing the net (loss) income attributable to ordinary shareholders by the weighted-average number of ordinary shares outstanding during the period. Diluted net (loss) income per share attributable to ordinary shareholders is computed using the more dilutive of (1) the two-class method or (2) the if-converted method. The Company allocatesallocated net income first to preferred shareholders based on dividend rights under the Company’s articles of association and then to preferred and ordinary shareholders based on ownership interests. Net losses arewere not allocated to preferred shareholders as they dodid not have an obligation to share in the Company’s net losses.

Diluted net (loss) income per share gives effect to all potentially dilutive securities. Potential dilutive securities consist of ordinary shares issuable upon the exercise of share options, ordinary shares issuable upon the vesting of restricted share units and awards and ordinary shares issuable upon the conversion of our convertible preferred shares.

Advertising and Promotion Costs

Expenses related to advertising and promotion of solutions is charged to sales and marketing expense as incurred. We incurred advertising expenses of $11.5 million, $5.6 million $3.7 million and $3.2$3.7 million during the years ended March 31, 2017, 2016 2015 and 2014,2015, respectively.

Income Taxes

We account for income taxes in accordance with ASC 740,Income Taxes. ASC 740 is an asset and liability approach that requires recognition of deferred tax assets and liabilities for the expected future tax consequences

attributable to differences between the carrying amounts of assets and liabilities for financial reporting purposes and their respective tax basis, and for operating loss and


tax credit carryforwards. ASC 740 requires a valuation allowance against net deferred tax assets if, based upon the available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized.

We recognize the tax benefit from an uncertain tax position only if it is more likely than not the tax position will be sustained on examination by the tax authorities, based on the technical merits of the position. The tax benefits recognized in the consolidated financial statements from such position are then measured based on the largest benefit that has a greater than 50% likelihood of being realized upon settlement. As of March 31, 20162017 and 2015,2016, we did not have any uncertain tax positions that would impact our net tax provision.provision if recognized.

Share-Based Compensation

The Company accounts for share-based compensation in accordance with the provisions of ASC 718,Compensation—Stock Compensation, which requires the recognition of expense related to the fair value ofshare-based compensation awards in the statements of operations. For share options issued under the Company’s share-based compensation plans to employees and members of the Board of Directors (the Board) for their services on the Board, the fair value of each option grant is estimated on the date of grant, and an estimated forfeiture rate is used when calculating share-based compensation expense for the period. For restricted share awards and restricted share units issued under the Company’s share-based compensation plans, the fair value of each grant is calculated based on the Company’s share price on the date of grant. For service-based awards, the Company recognizes share-based compensation expense on a straight-line basis over the requisite service period of the award. For awards subject to both performance and service-based vesting conditions, the Company recognizes share-based compensation expense using an accelerated recognitionattribution method when it is probable that the performance condition will be achieved. Forfeitures are required to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. For share-based awards classified as liabilities, the Company accounts for such liability such that the compensation expense will be remeasured at each reporting date until such award is settled. Total compensation expense related toThere we no outstanding liability awards was not material for the years endedas of March 31, 2016, 20152017 and 2014.2016.

The Company accounts for transactions in which services are received from non-employees in exchange for equity instruments based on the fair value of such services received, or of the equity instruments issued, whichever is more reliably measured. The Company determines the total share-based compensation expense related to non-employee awards using the Black-Scholes option-pricing model. Additionally, in accordance with ASC 505,Equity-Based Payments to Non-Employees, the Company accounts for awards to non-employees prospectively, such that the fair value of the awards will be remeasured at each reporting date until the earlier of (a) the performance commitment date or (b) the date the services required under the arrangement have been completed. During the year ended March 31, 20152016, the Company issued a share-based award to a non-employee in consideration for consulting services. The Company did not issue any share-based awards to non-employees during the years ended March 31, 20162017 and 2014.2015.

The fair value of each option grant issued under the Company’s share-based compensation plans was estimated using the Black-Scholes option-pricing model that used the following weighted-average assumptions presented in the following table:assumptions:

The weighted-average per share fair value of options granted to employees during the years ended March 31, 2017, 2016 and 2015 was $8.65, $4.69 and 2014 was $4.69, $4.02 and $1.56 per share, respectively.

The expected term of options for service-based awards has been determined utilizing the “Simplified Method,” as the Company does not have sufficient historical share option exercise information on which to base its estimate. The Simplified Method is based on the average of the vesting tranches and the contractual life of each grant. In addition, the expected term for certain share-based awards which are subject to service-based and performance-based vesting conditions, is based on management’s estimate of the period of time for which the instrument is expected to be outstanding, factoring in certain assumptions such as the vesting period of the award, length of service and/or the location of the employee. The risk-free interest rate is based on a treasury instrument whose term is consistent with the expected lifeterm of the share option. Since there was no public market for its ordinary shares prior to completion of the Company’s initial public offering (IPO) and as the Company’s shares have been publicly traded for a limited time, the Company determined the expected volatility for options granted based on an analysis of reported data for a peer group of companies that issue options with substantially similar terms. The expected volatility of options granted has been determined using an average of the historical volatility


measures of this peer group of companies. The Company has not paid, nor anticipates paying, cash dividends on its ordinary shares; therefore, the expected dividend yield is assumed to be zero. Since the IPO, the share option price is based on the fair market value of the Company’s ordinary shares at the time of each grant.

Prior to the IPO, in the absence of an active market for the Company’s ordinary shares, the Board, the members of which the Company believes have extensive business, finance, and venture capital experience, were required to estimate the fair value of the Company’s ordinary shares at the time of each grant of a share-based award. The Company and the Board utilized various valuation methodologies in accordance with the framework of the American Institute of Certified Public Accountants’ Technical Practice Aid, Valuation of Privately-Held Company Equity Securities Issued as Compensation, to estimate the fair value of its ordinary shares. Each valuation methodology includesincluded estimates and assumptions that requirerequired the Company’s judgment. These estimates and assumptions includeincluded a number of objective and subjective factors in determining the value of the Company’s ordinary shares at each grant date, including the following factors:following: (1) prices paid for the Company’s convertible preferred shares, which the Company had sold to outside investors in arm’s-length transactions, and the rights, preferences, and privileges of the Company’s convertible preferred shares and ordinary shares; (2) valuations performed by an independent valuation specialist; (3) the Company’s stage of development and revenue growth; (4) the fact that the grants of share-based awards involved illiquid securities in a private company; and (5) the likelihood of achieving a liquidity event for the ordinary shares underlying the share-based awards, such as an IPO or sale of the Company, given prevailing market conditions.

The Company believes this methodology to behave been reasonable based upon the Company’s internal peer company analyses, and further supported by several arm’s-length transactions involving the Company’s convertible preferred shares. As the Company’s ordinary shares were not actively traded prior to the IPO, the determination of fair value involves assumptions, judgments and estimates. If different assumptions were made, share-based compensation expense, consolidated net (loss) income and consolidated net (loss) income per share could have been significantly different.

Since the IPO, the fair value of the Company’s ordinary shares at the time of each grant of a share-based award have been based on the market value at the time of each grant.

See Note 810 for a summary of the share option activity for the yearsyear ended March 31, 2016 and 2015.2017.

Leases

The Company categorizes leases at their inception as either operating or capital leases. On certain lease agreements, the Company may receive rent holidays and other incentives. The Company recognizes lease costs on a straight-line basis once control of the space is achieved, without regard to deferred payment terms, such as rent holidays that defer the commencement date of required payments or escalating payment amounts. The

difference between required lease payments and rent expense has been recorded as deferred rent. Additionally, incentives received are treated as a reduction of costs over the term of the agreement, as they are considered an inseparable part of the lease agreement.

Comprehensive Income (Loss)Loss

Comprehensive income (loss)loss is defined as the change in equity of a business enterprise during a period from transactions, other events, and circumstances from non-owner sources. Comprehensive income (loss)loss consists of net (loss) income and other comprehensive income (loss),loss, which includes certain changes in equity that are excluded from net (loss) income. Specifically, cumulative foreign currency translation adjustments and unrealized gains and losses on investments are included in accumulated other comprehensive income (loss).loss. As of March 31, 20162017 and 2015,2016, accumulated other comprehensive income (loss) is presented separately on the consolidated balance sheets and consists entirely of cumulative foreign currency translation adjustments.adjustments and unrealized gains and losses on investments.

Recently Issued Accounting Pronouncements

From time to time, new accounting pronouncements are issued by the FASB or other standard setting bodies and adopted by the Company as of the specified effective date. Unless otherwise discussed, the Company believes that the impact of recently issued standards that are not yet effective will not have a material impact on its financial position or results of operations upon adoption.

In May 2014, the FASB issued ASU No. 2014-09,Revenue from Contracts with Customers: Topic 606 (ASU 2014-09), to supersede nearly all existing revenue recognition guidance under U.S. GAAP. The core principle of ASU 2014-09 is to recognize revenues when promised goods or services are transferred to customers in an amount that reflects the consideration that is expected to be received for those goods or services. ASU 2014-09 defines a five step process to achieve this core principle and, in doing so, it is possible more judgment and estimates may be required within the revenue recognition process than required under existing U.S. GAAP, including identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation. This guidance wasis effective for annual reporting and interim periods beginning after December 15, 20162017 including interim reporting periods within that reporting period and allows for either full retrospective or modified retrospective application, with earlyapplication. Early adoption notis permitted. On July 9, 2015


The Company is still evaluating the FASB votedimpact that this guidance will have on its financial statements and related disclosures. Based on the Company’s procedures performed to approvedate, nothing has come to its attention that would indicate that the adoption of ASU 2014-09 will have a one-year deferral of the effective date of this guidance. In accordance with the agreed upon delay, the guidancematerial impact on its revenue recognition, however, further analysis is effective forrequired and the Company will continue to evaluate this assessment in fiscal 2018. Additionally, the Company has made a preliminary assessment that there will be an impact relating to the accounting for costs to acquire a contract. Under the standard, the Company will likely be required to capitalize certain costs, primarily commission expense to sales representatives, on its consolidated balance sheet and amortize such costs over the contractual term or the average customer life. The Company is still evaluating the impact of capitalizing costs to execute a contract. The Company intends to adopt ASU 2014-09 on April 1, 2018. The Company is currently evaluating the adoption method it will apply and the impact of the adoption of ASU 2014-09 on its consolidated financial statements.apply.

In August 2014, the FASB issued ASU No. 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern. ASU 2014-15 requires management to evaluate, at each annual or interim reporting period, whether there are conditions or events that exist that raise substantial doubt about an entity’s ability to continue as a going concern within one year after the date the financial statements are issued and provide related disclosures. ASU 2014-15 is effective for annual periods ending after December 15, 2016 and earlier application is permitted. The Company is currently evaluating the impact of the adoption of ASU2014-15, but the adoption is not expected to have a material effect on its consolidated financial statements or disclosures.

In February 2015, the FASB issued ASU No. 2015-02, Consolidation (Topic 810)-Amendments to the Consolidation Analysis, which amends the criteria for determining which entities are considered variable interest entities, or VIEs, amends the criteria for determining if a service provider possesses a variable interest in a VIE and ends the deferral granted to investment companies for application of the VIE consolidation model. ASU 2015-02 is effective for annual periods, and interim periods therein, beginning after December 15, 2015. The Company is currently evaluating the impact the adoption of ASU 2015-02 will have on its financial statements.

In April 2015, the FASB issued ASU No. 2015-03,Simplifying2015-05, Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40), Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement (ASU 2015-05). ASU 2015-05 provides guidance to customers about whether a cloud computing arrangement includes a software license. If a cloud computing arrangement includes a software license, then the Presentationcustomer should account for the software license element of Debt Issuance Costs(ASU 2015-03), which requires the Company to present such costs inarrangement consistent with the balance sheetacquisition of other software licenses. If a cloud computing arrangement does not include a software license, the customer should account for the arrangement as a direct deduction from the related debt liability rather than as an asset. Amortization of the costs will continue to be reported as interest expense. ASU 2015-03 will be effective for annual reporting periods beginning after December 15, 2015 and interim periods within fiscal years beginning after December 15, 2016, with early adoption permitted.service contract. The new guidance will be applied retrospectivelynot change GAAP for a customer’s accounting for service contracts. The ASU aims to each prior period presented.reduce complexity and diversity in practice. The Company is currently in the process of evaluating the impactadopted this standard prospectively on April 1, 2016 and timing of adoption of the ASU 2015-03, but the adoption isdid not expected to have a material effectimpact on its consolidated financial statements or disclosures.statements.

In November 2015, the FASB issued ASU No. 2015-17,Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes(ASU 2015-17). The amendment requires entities with a classified balance sheet to present all deferred tax assets and liabilities as noncurrent. The ASU is effective for annual periods, including interim periods within those annual periods, beginning after December 15, 2016. Early adoption is permitted. The Company retrospectively adopted ASU 2015-17 on April 1, 2016 and the adoption did not have a material impact on its consolidated financial statements.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) (ASU 2016-02). ASU 2016-02 requires a lessee to recognize most leases on the balance sheet but recognize expenses on the income statement in a manner similar to current practice. The update states that a lessee will recognize a lease liability for the obligation to make lease payments and a right-to-use asset for the right to use the underlying assets for the lease term. Leases will continue to be classified as either financing or operating, with classification affecting the recognition, measurement and presentation of expenses and cash flows arising from a lease. ASU 2016-02 is effective for financial statements issued for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. The Company is currently in the process of evaluating the impact and timing of adoption of the ASU 2015-172016-02 on its consolidated financial statements.

In March 2016, the FASB issued ASU No. 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting (ASU 2016-09). The ASU amends the codification to simplify2016-09 simplifies several aspects of the accounting for share-based payment award transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. The ASU 2016-09 is effective for annual periods, includingfiscal years, and interim periods within those annual periods, beginning after December 15, 2016. Early2016 and allows for prospective, retrospective or modified retrospective adoption, depending on the area covered in the update, with early adoption permitted.

The Company will adopt this guidance in its first quarter of 2018. Upon adoption, the Company will record any excess tax benefits or deficiencies from its equity awards in its consolidated statements of operations in the reporting periods in which vesting or exercise occurs. Subsequent to adoption, the Company's income tax expense and associated effective tax rate will be impacted by fluctuations in stock price between the grant dates and vesting or exercise dates of equity awards. This guidance will be adopted using a modified retrospective transition method, however the adoption is not expected to have a material impact to the Company’s deferred tax assets or retained earnings on its consolidated balance sheets.

In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (ASU 2016-15). ASU 2016-15 is intended to add or clarify guidance on the classification of certain cash receipts and payments in the statement of cash flows and to eliminate the diversity in practice related to such classifications. The guidance in ASU 2016-15 is required for annual reporting periods beginning after December 15, 2017, with early adoption permitted. The Company is currently in the process of evaluating the impact and timing of adoption of the ASU 2016-15 on its consolidated financial statements.

In October 2016, the FASB issued ASU No. 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory (ASU 2016-16). The purpose of ASU 2016-16 is to simplify the income tax accounting of an intra-entity transfer of an asset other than inventory and to record its effect when the transfer occurs. The guidance is effective for annual reporting periods beginning after December 15, 2017, including interim reporting periods within those annual reporting periods and early adoption is permitted.


The Company intends to adopt ASU 2016-16 on April 1, 2018. The Company is currently in the process of evaluating the impact and timing of adoption of the ASU 2016-16 on its consolidated financial statements.

In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash (ASU 2016-18). ASU 2016-18 requires that the statement of cash flows explain the change during the period in the total of cash, cash equivalents and amounts generally described as restricted cash or restricted cash equivalents. Entities will also be required to reconcile such total to amounts on the balance sheet and disclose the nature of the restrictions. The guidance is effective for annual reporting periods beginning after December 15, 2017 and interim periods within those fiscal years and early adoption is permitted. The Company is currently in the process of evaluating the impact and timing of adoption of the ASU 2016-092016-18 on its consolidated financial statements.

In January 2017, the FASB issued ASU No. 2017-04, Simplifying the Test for Goodwill Impairment (ASU 2017-04). The standard eliminates the second step in the goodwill impairment test which requires an entity to determine the implied fair value of the reporting unit’s goodwill. The standard is effective for annual and interim goodwill impairment tests conducted in fiscal years beginning after December 15, 2019, with early adoption permitted. The Company is currently in the process of evaluating the impact and timing of adoption of the ASU 2017-04 on its consolidated financial statements.

4. RestructuringAcquisitions

DuringOn November 21, 2016, the Company entered into an Asset Purchase Agreement (APA) to purchase substantially all of the assets of iSheriff, Inc. (iSheriff), a cloud-based security provider. This acquisition will provide Mimecast’s customers additional real-time email threat intelligence and detection expertise and complements the Company’s existing portfolio of email security, continuity and archiving solutions.

The total preliminary purchase price of $6.2 million consisted of a cash payment of approximately $5.6 million, subject to certain adjustments, and $0.6 million in purchase price held backin respect of claims for indemnification for one year from the purchase date. Additionally, the APA includes contingent consideration related to a discretionary purchase price in the amount of $2.0 million which is payable at the sole and absolute discretion of the Company on the one year anniversary of the purchase date. The Company considers the payment of the discretionary purchase price to be remote and has determined the fair value of the contingent consideration to be zero.

The acquisition of iSheriff has been accounted for as a business combination and, in accordance with ASC 805, the Company has recorded the assets acquired and liabilities assumed at their respective fair values as of the acquisition date. The following table summarizes the preliminary purchase price allocation as of March 31 2017:

In the year ended March 31, 2015,2017, acquisition-related expenses of $0.7 million were expensed as incurred and included in general and administrative expenses in the Company recorded a restructuring charge of $1.2 million within the accompanying consolidated statements of operations. The restructuring charge consistedoperating results of employee severanceiSheriff have been included in the consolidated statements of operations beginning on the acquisition date.

The significant intangible assets identified in the preliminary purchase price allocation discussed above include developed technology and customer relationships, which are amortized over their respective useful lives on a straight line basis. The preliminary allocation of the purchase price may be subject to revisions as additional information is obtained about the facts and circumstances that existed at the time of acquisition. To value the developed technology asset, the Company utilized the income approach, specifically a discounted cash-flow method known as the multi-period excess earnings method. Customer relationships represent the underlying relationships with certain customers to provide ongoing services for products sold. The Company utilized the income approach, specifically the distribution method which is a subset of the excess-earnings method, to value the customer relationships.


A portion of the purchase price has been allocated to intangible assets and goodwill, respectively, and is reflected in the tables above. The fair value of the assets acquired and liabilities assumed is less than the purchase price, resulting in the recognition of goodwill. The goodwill reflects the value of the synergies we expect to realize and the assembled workforce and is not deductible for tax purposes. The purchase price has been allocated to the tangible and intangible assets acquired and liabilities assumed based upon the respective estimates of fair value as of the date of the acquisition and using assumptions that the Company’s management believes are reasonable.

6. Fair Value Measurement

The Company’s financial instruments include cash, cash equivalents, accounts receivable, investments, accounts payable, accrued expenses, capital lease obligations and long-term debt.  The carrying amount of the Company’s long-term debt and capital lease obligations approximate their fair values due to the interest rates the Company believes it could obtain for arrangements with similar terms.  The Company’s investments are classified as available-for-sale and reported at fair value in accordance with the market approach utilizing quoted prices that were directly or indirectly observable. The carrying amount of the remainder of the Company’s financial instruments approximated their fair values as of March 31, 2017 and 2016, due to the short-term nature of those instruments.

The Company has evaluated the estimated fair value of financial instruments using available market information. The use of different market assumptions and/or estimation methodologies could have a significant effect on the estimated fair value amounts.

Fair values determined using “Level 1 inputs” utilize unadjusted quoted prices in active markets for identical assets or liabilities that we have the ability to access.  Fair values determined using "Level 2 Inputs" utilize quoted prices that are directly or indirectly observable. Fair values determined using “Level 3 inputs” utilize unobservable inputs for determining fair values of assets or liabilities that reflect an entity's own assumptions in pricing assets or liabilities. As of March 31, 2017 and 2016, we did not have any assets or liabilities measured at fair value on a recurring basis using significant unobservable inputs (Level 3).

The following table summarizes financial assets measured and recorded at fair value on a recurring basis in the accompanying consolidated balance sheets as of March 31, 2017 and 2016, segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value:

10. Share-based compensation

AtAs of March 31, 2016,2017, the Company has four share-based compensation plans and an employee stock purchase plan, which are more fully described below.

Prior to the IPO, the Company granted share-based awards under three share option plans which are the Mimecast Limited 2007 Key Employee Share Option Plan (the 2007 Plan), the Mimecast Limited 2010 EMI Share Option Scheme (the 2010 Plan), and the Mimecast Limited Approved Share Option Plan (the Approved Plan) (the 2007 Plan, the 2010 Plan and the Approved Plan, collectively, the Historical Plans).

Upon the closing of the IPO, the Mimecast Limited 2015 Share Option and Incentive Plan (the 2015 Plan) and the 2015 Employee Stock Purchase Plan (the 2015 ESPP) became effective. Subsequent to the IPO, future grants of share-based awards will behave been made under the 2015 Plan and no further grants under the Historical Plans are permitted.

The 2015 Plan was adopted by our board of directorsthe Board on September 2, 2015, approved by our shareholders on November 4, 2015 and became effective on the date of the Company’s IPO. The 2015 Plan allows the compensation committee to make equity-based


incentive awards to our officers, employees, non-employee directors and consultants. Initially a total of 5,500,000 ordinary shares were reserved for the issuance of awards under the 2015 Plan. This number is subject to adjustment in the event of a share split, share dividend or other change in our capitalization. The 2015 Plan provides that the number of shares reserved and available for issuance under the plan will automatically increase each January 1, beginning on January 1, 2016, by 5% of the outstanding number of ordinary shares on the immediately preceding December 31 or such lesser number of shares as determined by our boardthe Board.The number of directors.options available for future grant under the 2015 Plan as of March 31, 2017 was 6,420,116.

In September 2015, our board of directorsthe Board adopted the Mimecast Limited 2015 Employee Share Purchase Plan (ESPP),ESPP which was approved by our shareholders on November 4, 2015. The ESPP initially reserves and authorizes for issuance a total of 1,100,000 ordinary shares. This number is subject to adjustment in the event of a share split, share dividend or other change in our capitalization. Participating employees of the Company may purchase ordinary shares during pre-specified purchase periods at a price equal to the lesser of 85% of the fair market value of an ordinary share of the Company at the beginning of the purchase period or 85% of the fair market value of an ordinary share of the Company at the end of the purchase period. The Board has not determinedauthorized that the date on whichfirst six-month offering period under the initial purchase periodESPP will commence under the ESPP.on July 1, 2017.

Under the 2015 Plan, the share option price may not be less than the fair market value of the ordinary shares on the date of grant and the term of each share option may not exceed 10 years from the date of grant. Share

options typically vest over 4 years, but vesting provisions can vary based on the discretion of the Board. We settleThe Company settles share optionsoption exercises under the 2015 PlansPlan through newly issued shares. The Company’s ordinary shares underlying any awards that are forfeited, canceled, withheld upon exercise of an option, or settlement of an award to cover the exercise price or tax withholding, or otherwise terminated other than by exercise will be added back to the shares available for issuance under the 2015 Plan.

Under the Historical Plans, share-based awards have a term of 10 years from the date of grant and typically vest over 4 years, however, vesting provisions could vary based on the discretion of the Board. Subsequent to the Company’s IPO, the Company’s ordinary shares underlying any awards issued under the Historical Plans that are forfeited, canceled, withheld upon exercise of an option, or settlement of an award to cover the exercise price or tax withholding, or otherwise terminated other than by exercise will be not be added back to the shares available for issuance.issuance under the Historical Plans.

Certain awards granted by the Company under the Historical Plans are subject to service-based vesting conditions and a performance-based vesting condition based on a liquidity event, defined as either a change of control or an IPO. As a result, no compensation cost related to share-based awards with these performance conditions had been recognized through the date of the Company’s IPO, which occurred in November 2015, as the Company had determined that a liquidity event was not probable. Upon the IPO, 100% of the unvested portion of options granted under the Historical Plans prior to May 13, 2014 became vested. For options issued to employees other than those in our USthe Company’s U.S. subsidiary, 25% of the vested shares underlying options became exercisable immediately upon the listing, 50% of the vested shares underlying options will becomebecame exercisable 12 months following the date of the listing, and 25% of the vested shares underlying options will become exercisable 24 months following the date of the listing. Upon consummationSince the closing of the IPO, the Company began to recordhas recognized expense for these awards using the accelerated attribution method over the remaining service period. Options granted on or after May 13, 2014 under the 2010 Plan, and the Approved Plan shall continue vesting as set forth in the option award agreements and the Approved Plan shall continue vesting as set forth in the option award agreements.

In certain situations, the Board has approved modifications to employee share option agreements, including the removal of exercise restrictions for share options for which the service based vesting has been satisfied which resulted in additional share-based compensation expense. The number of options available for future grant undertotal modification expense in the Plans as ofyears ended March 31, 2017, 2016 and 2015 was 5,999,375.$3.0 million, $1.4 million and $4.2 million, respectively.

Litigation

The Company, from time to time, may be party to litigation arising in the ordinary course of its business. The Company was not subject to any material legal proceedings during the years ended March 31, 2017, 2016 2015 and 2014,2015, and, to the best of its knowledge, no material legal proceedings are currently pending or threatened.

Indemnification

The Company typically enters into indemnification agreements with customers in the ordinary course of business. Pursuant to these agreements, the Company indemnifies and agrees to reimburse the indemnified party for losses suffered or incurred as a result of claims of intellectual property infringement. These indemnification agreements are provisions of the applicable customer agreement. Based on when clients first sign an agreement for the Company’s service, the maximum potential amount of future payments the Company could be required to make under certain of these indemnification agreements is unlimited. Based on historical experience and information known as of March 31, 2016,2017, the Company has not incurred any costs for the above guarantees and indemnities.

In certain circumstances, the Company warrants that its services will perform in all material respects in accordance with its standard published specification documentation in effect at the time of delivery of the services to the customer for the term of the agreement. To date, the Company has not incurred significant expense under its warranties and, as a result, the Company believes the estimated fair value of these agreements is immaterial.

In assessing the ability to realize the Company’s net deferred tax assets, management considers various factors including taxable income in carryback years, future reversals offor existing taxable temporary differences, tax planning strategies, and projections of future taxable income projections to determine whether it is more likely than not that some portion or all of the net deferred tax assets will not be realized. Based on the cumulative losses that the Company has incurred in the jurisdictions in which it operates and consideration ofconsidering other negative evidence, the Company has determined that the uncertainty regarding the realization ofrealizing its deferred tax assets is sufficient to warrant the need for a full valuation allowance against its worldwide net deferred tax assets. The approximately $3.6 million net decrease in the valuation allowance of approximately $1.3 million from 20152016 to 20162017 is primarily due to the impact oftax reserves established against certain foreign exchange, the impact ofnet operating loss carryforwards, deferred tax true-up adjustments, and thecurrent year operating results of the Company.and foreign exchange.
