Recently Issued Accounting Standards
From time to time, new accounting pronouncements are issued by the FASB and are adopted by us as of the specified effective dates. Unless otherwise discussed, such pronouncements did not have or will not have a significant impact on our consolidated financial position, results of operations and cash flows or do not apply to our operations.
In August 2016, the FASB issued ASU 2016-15, "Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments" ("ASU 2016-15"), which provides guidance on the classification of certain specific cash flow issues including debt prepayment or extinguishment costs, settlement of certain debt instruments, contingent consideration payments made after a business combination, proceeds from the settlement of certain insurance claims and distributions received from equity method investees. The standard requires the use of a retrospective approach to all periods presented, but may be applied prospectively if retrospective application would be impracticable. ASU 2016-15 is effective for us infiscal years beginning after December 15, 2017 and the first quarter of fiscal year 2019, andinterim periods therein, with early applicationadoption permitted. The guidance requires cash flows with multiple characteristics to be classified using a three-step process, including (i) determining whether explicit guidance is permitted. We are currently evaluating the impact of our pending adoption of ASU 2016-15 on our statementapplicable, (ii) separating each identifiable source or use of cash flows, butand (iii) determining the predominant source or use of cash flows when the source or use of cash flows cannot be separately identifiable. The guidance will be applied retrospectively to each period presented. We do not expect itthe implementation to have a material impact.
In March 2016, the FASB issued ASU No. 2016-09, "Improvements to Employee Share-Based Payment Accounting" ("ASU 2016-09"), which is intended to simplify several aspects of the accounting for share-based payment transactions, including the income tax effects, statutory withholding requirements, forfeitures, and classification on the statement of cash flows. ASU 2016-09 is effective for us in the first quarter of fiscal year 2018, and early application is permitted. We are currently evaluating the impact of our pending adoption of ASU 2016-09 on our consolidated financial statements but do not expect it to have a material impact.statements.
In February 2016, the FASB issued ASU No. 2016-02, "Leases" ("ASU 2016-02"). ASU 2016-02 requires lessees to recognize on the balance sheet a right-of-use asset, representing its right to use the underlying asset for the lease term, and a lease liability for all leases with terms greater than 12 months. The guidance also requires qualitative and quantitative disclosures designed to assess the amount, timing, and uncertainty of cash flows arising from leases. The standard requires the use of a modified retrospective transition approach, which includes a number of optional practical expedients that entities may elect to apply. ASU 2016-02 is effective for us in the first quarter of fiscal year 2020, and early application is permitted. We are currently evaluating the impact of our pending adoption of ASU 2016-02 on our consolidated financial statements, and we currently expect that most of our operating lease commitments will be subject to the new standard and recognized as operating lease liabilities and right-of-use assets upon our adoption of ASU 2016-02, which will increase our total assets and total liabilities that we report relative to such amounts prior to adoption.

In January 2016, the FASB issued ASU No. 2016-01, "Recognition and Measurement of Financial Assets and Financial Liabilities" ("ASU 2016-01"). ASU 2016-01 amends the guidance on the classification and measurement of financial instruments. Although ASU 2016-01 retains many current requirements, it significantly revises accounting related to the classification and measurement of investments in equity securities and the presentation of certain fair value changes for financial liabilities measured at fair value. ASU 2016-01 also amends certain disclosure requirements associated with the fair value of financial instruments and is effective for us in the first quarter of fiscal year 2019. Based on the composition of our investment portfolio, we do not believe the adoption of ASU 2016-01 will have a material impact on our consolidated financial statements.
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 stepfive-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. ASU 2014-09 permits two methods of adoption: (i) retrospective to each prior reporting period presented; or (ii) retrospective with the cumulative effect of initially applying the guidance recognized at the date of initial application. In August 2015, the FASB issued ASU No. 2015-14, Revenue from Contracts with Customers: Deferral of the Effective Date, which deferred the effective date of the new revenue standard for periods beginning after December 15, 2016 to December 15, 2017, with early adoption permitted but not earlier than the original effective date.  Accordingly, the updated standard is effective for us in the first quarter of fiscal 2019 and we do not plan to early adopt. In the first quarter of fiscal 2017, we commenced a project to assess the potential impact of the new standard on our consolidated financial statements and related disclosures. This project also includes the assessment and enhancement of our internal processes and systems to address the new standard. While we are continuing to assess all potential impacts of the new standard, we currently believe the most significant impact relates to our accounting for arrangements that include term-based software licenses bundled with maintenance and support. Under current GAAP, the revenue attributable to these software licenses is recognized ratably over the term of the arrangement because vendor-specific objective evidence ("VSOE") does not exist for the undelivered maintenance and support element as it is not sold separately. The requirement to have VSOE for undelivered elements to enable the separation of revenue for the delivered software licenses is eliminated under the new standard. Accordingly, under the new standard we will be required to recognize as revenue a portion of the arrangement fee upon delivery of the software license. While we currently expect revenue related to our professional services and cloud offerings to remain substantially unchanged, we are still in the process of evaluating the impact of the new standard on these arrangements. We plan to adopt this guidance beginning on October 1, 2018 and apply the cumulative catch-up transition method, with a cumulative adjustment to retained earnings as opposed to retrospectively adjusting prior periods.
3. Business Acquisitions
We continue to expand our solutions and integrate our technologies in new offerings through acquisitions. A summary of our acquisition activities is as follows:
Fiscal Year 2018
For the six months ended March 31, 2018, we completed an acquisition in our Healthcare segment for a total cash consideration of $8.7 million and contingent payments with a fair value of $0.5 million. As a result, we recognized goodwill of $6.8 million, and other intangible assets of $2.0 million, with a weighted average life of 2.0 years. The acquisition did not have a material impact on our condensed consolidated financial statements for the period.
In April 2018, we completed an acquisition in our Automotive segment for a total cash consideration of approximately $82 million, net of cash acquired. We are currently in the process of determining the total consideration transferred and the fair values of assets acquired and liabilities assumed, but do not yet selectedexpect this acquisition to have a transition method.material impact on our condensed consolidated financial statements.
Fiscal Year 2017
For the six months ended March 31, 2017, we completed several acquisitions in our Enterprise, Healthcare and Mobile segments for a total cash consideration of $34.4 million, 0.8 million shares of common stock valued at $13.4 million and contingent payments with a fair value of $2.0 million. As a result, we recognized goodwill of $27.0 million, and other intangible assets of $22.5 million, with a weighted average life of 6.2 years. Such acquisitions were not significant individually or in the aggregate.

3.Business Acquisitions
As part of our business strategy, we have acquired, and may acquire in the future, certain businesses and technologies primarily to expand our products and service offerings.
Fiscal Year 2017 Acquisitions
In fiscal year 2017, we acquired several businesses in our Enterprise, Healthcare and Mobile segments that were not significant individually or in the aggregate. The total aggregate consideration for these acquisitions was $53.5 million, including the issuance of 0.8 million shares of our common stock valued at $13.4 million and a $3.3 million estimated fair value for future contingent payments. The results of operations of these acquisitions have been included in our financial results since their respective acquisition dates.
The fair value estimates for the assets acquired and liabilities assumed for acquisitions completed during fiscal year 2017 were based upon preliminary calculations and valuations, and our estimates and assumptions for each of these acquisitions are subject to change as we obtain additional information during the respective measurement periods (up to one year from the respective acquisition dates). The primary areas of preliminary estimates that were not yet finalized related to certain assets and liabilities acquired. There were no significant changes to the fair value estimates during the current year.
We have not furnished pro forma financial information related to our current year acquisitions because such information is not material, individually or in the aggregate, to our financial results. We have also not presented revenue or the results of operations for each of these business combinations, from the date of acquisition, as they were similarly neither material nor significant to our consolidated financial results.
Fiscal Year 2016 Acquisitions
Acquisition of TouchCommerce, Inc. 
In August 2016, we acquired all of the outstanding stock of TouchCommerce. TouchCommerce is a provider of omni-channel solutions to engage their customers on any device through online chat, guides, personalized content, and other automated tools, resulting in enhanced customer experience, increased revenue and reduced support costs. We expect this acquisition to expand our customer care solutions with a range of new digital engagement offerings, including live chat, customer analytics and personalization solutions within our Enterprise segment. We expect to be able to provide an end-to-end engagement platform that merges intelligent self-service with assisted service to increase customer satisfaction, strengthen customer loyalty and improve business results. The aggregate consideration for this transaction was $218.1 million, and included $113.0 million paid in cash and $85.0 million paid in our common stock. The remaining $20.1 million is expected to be paid in November 2017 at the conclusion of an indemnity period in either cash or our common stock, at our election. The acquisition was a stock purchase and the goodwill resulting from this acquisition is not deductible for tax purposes. The results of operations for this acquisition have been included in our Enterprise segment from the acquisition date.

In addition, we moved our Dragon TV business from our Mobile operating segment into our Enterprise operating segment.
As a result of the reorganization, the original Mobile reporting unit was separated into three discrete lines of business comprised of Automotive, Dragon TV, and Devices. We assigned $1,080.5 million, $12.0 million, and $36.0 million of goodwill to Automotive, Dragon TV and Devices, respectively, based on their relative fair values as of March 31, 2018, and assessed the assigned goodwill

for impairment by comparing each component’s fair value to its carrying amount. The fair values of Automotive and Dragon TV significantly exceeded their carrying amounts. However, the carrying value of Devices exceeded its fair value by $35.1 million. The standalone multi-year operating plan reflects the ongoing consolidation of our handset manufacturer customer base and continued erosion of our penetration of the remaining market. As a result, we recorded a $35.1 million goodwill impairment for the second quarter of fiscal 2018. After the impairment charge, the goodwill assigned to Devices as of March 31, 2018 was immaterial. The reorganization did not result in January 2017.any impairment charge of other intangible assets for the second quarter of fiscal 2018.
Also during the second quarter of fiscal 2018, our Subscriber Revenue Services ("SRS") reporting unit, originally included within our Mobile operating segment, recorded significantly lower revenue and profitability due to recent market disruptions in certain markets that we serve. Our SRS business provides value-added services to mobile operators in emerging markets, primarily in India and Brazil. These markets have experienced recent and dramatic disruption as a result of accelerated change in competition and business models for our mobile operator customers. Specifically, the rapid shift away from a model where voice, data and text are offered separately toward unlimited bundled services at considerably lower costs has significantly reduced mobile operators’ demand for our services. This reduced demand materially impacts our future expectations for SRS revenues. As a result, executive management performed an updated strategic assessment and reduced the long-term growth rates and profitability contemplated in SRS's multi-year operating plan. We concluded that these financial results coupled with the rapid market shifts being experienced in the industry were factors that represented impairment indicators, triggering a review of goodwill and indefinite-lived intangible assets for impairment during the second quarter of fiscal 2018. Based on the result of the impairment assessment, the carrying value of SRS exceeded its fair value by $94.3 million. In addition, we recorded an $8.5 million deferred tax benefit related to SRS’s goodwill, which is amortized over time for tax purposes, and therefore increased the impairment charge by the same amount. As a result, we recorded a goodwill impairment charge of $102.8 million related to SRS for the second quarter of fiscal 2018. After the impairment charge, goodwill assigned to SRS was $17.8 million as of March 31, 2018. The assessment did not result in any impairment charge of other intangible assets for the second quarter of fiscal 2018.

For the purpose of the goodwill impairment analysis, the carrying value of each reporting unit is determined based on the allocation of assets and liabilities to the reporting unit based on the reporting unit’s revenue and operating expenses as a percentage of our consolidated revenue and operating expenses. Certain corporate assets and liabilities that are not directly attributable to the reporting unit’s operations and would not be transferred to a hypothetical purchaser of the reporting unit are excluded from the reporting unit’s carrying amount.

The fair value of a reporting unit is generally determined using a combination of the income approach and the market approach, where the income approach is weighted 50% and the market approach 50%. The fair values of Devices and Dragon TV, however, were determined solely based upon the income approach due to the lack of comparable public companies or comparable acquisitions. For the income approach, fair value is determined based on the present value of estimated future after-tax cash flows, discounted at an appropriate risk-adjusted rate. We use our internal forecasts to estimate future after-tax cash flows and estimate the long-term growth rates based on our most recent views of the long-term outlook for each reporting unit. Actual results may differ from those assumed in our forecasts. We derive our discount rates using a capital asset pricing model and analyzing published rates for industries relevant to our reporting units to estimate the weighted average cost of capital. We use discount rates that are commensurate with the risks and uncertainty inherent in the respective businesses and in our internally developed forecasts. For the market approach, we use a valuation technique in which values are derived based on valuation multiples of comparable publicly traded companies. We assess each valuation methodology based upon the relevance and availability of the data at the time we perform the valuation and weight the methodologies appropriately.

Determining the fair value of a reporting unit involves the use of significant estimates and assumptions, all of which we believe are reasonable but nevertheless inherently uncertain. These estimates and assumptions include revenue growth rates and operating margins used to estimate future cash flows, risk-adjusted discount rates, future economic and market conditions, and the use of market comparables. Additionally, if we continue to experience lower-than-expected growth in a reporting unit or fail to sustain our profitability due to changing market dynamics, competition or technological obsolescence, it could adversely impact the long-term assumptions used in our goodwill impairment analysis. Such changes in assumptions and estimates may result in additional impairment of our goodwill and/or other long-lived assets, which could materially impact our future results of operations and financial conditions. Finally, as we continue to identify and assess other initiatives to better align our segment reporting structure with our long-term strategies, any additional changes in our organizational and segment reporting structure may result in additional impairment charges of goodwill and other intangible assets.

6.Fair Value MeasuresMeasurements
Fair value is defined as the price that would be received forto sell an asset, or paid to transfer a liability, in an orderly transaction between market participants at the measurement date. Valuation techniques must maximize the use of observable inputs and minimize the use of unobservable inputs. When determining the fair value measurements for assets and liabilities required to be recorded at fair value, we consider the principal or most advantageous market in which we would transact and consider assumptions that market participants would use when pricing the asset or liability, such as inherent risk, transfer restrictions, and risk of nonperformance.

5.625% Senior Notes due 2026
In December 2016, we issued $500.0 million aggregate principal amount of 5.625% Senior Notes due on December 15, 2026 (the "2026 Senior Notes") in a private placement. The proceeds from the 2026 Senior Notes were approximately $495.0 million, net of issuance costs, and we used the proceeds to repurchase a portion of our 2020 Senior Notes. The 2026 Senior Notes bear interest at 5.625% per year, payable in cash semi-annually in arrears, beginning on June 15, 2017.
The 2026 Senior Notes are unsecured senior obligations and are guaranteed on an unsecured senior basis by certain of our domestic subsidiaries ("Subsidiary Guarantors"). The 2026 Senior Notes and the guarantees rank equally in right of payment with all of our and the Subsidiary Guarantors’ existing and future unsecured senior debt and rank senior in right of payment to all of our and the Subsidiary Guarantors’ future unsecured subordinated debt. The 2026 Senior Notes and guarantees effectively rank junior to all our secured debt and that of the Subsidiary Guarantors to the extent of the value of the collateral securing such debt and to all liabilities, including trade payables, of our subsidiaries that have not guaranteed the 2026 Senior Notes.
At any time before December 15, 2021, we may redeem all or a portion of the 2026 Senior Notes at a redemption price equal to 100% of the aggregate principal amount of the 2026 Senior Notes to be redeemed, plus a “make-whole” premium and accrued and unpaid interest to, but excluding, the redemption date. At any time on or after December 15, 2021, we may redeem all or a portion of the 2026 Senior Notes at certain redemption prices expressed as percentages of the principal amount, plus accrued and unpaid interest to, but excluding, the redemption date. At any time and from time to time before December 15, 2021, we may redeem up to 35% of the aggregate outstanding principal amount of the 2026 Senior Notes with the net cash proceeds received by us from certain equity offerings at a price equal to 105.625% of the aggregate principal amount, plus accrued and unpaid interest to, but excluding, the redemption date, provided that the redemption occurs no later than 120 days after the closing of the related equity offering, and at least 50% of the original aggregate principal amount of the 2026 Senior Notes remains outstanding immediately thereafter.
Upon the occurrence of certain asset sales or a change in control, we must offer to repurchase the 2026 Senior Notes at a price equal to 100% in the case of an asset sale, or 101% in the case of a change of control, of the principal amount plus accrued and unpaid interest to, but excluding, the repurchase date.
5.375% Senior Notes due 2020

The 2020 Senior Notes bear interest at 5.375% per year, payable in cash semi-annually in arrears. The 2020 Senior Notes are our unsecured senior obligations and are guaranteed on an unsecured senior basis by certain of our domestic subsidiaries, ("the Subsidiary Guarantors"). The 2020 Senior Notes and guarantees rank equally in right of payment with all of our and the Subsidiary Guarantors' existing and future unsecured senior debt and rank senior in right of payment to all of our and the Subsidiary Guarantors' future unsecured subordinated debt. The 2020 Senior Notes and guarantees effectively rank junior to all secured debt of our and the Subsidiary Guarantors to the extent of the value of the collateral securing such debt and to all liabilities, including trade payables, of our subsidiaries that have not guaranteed the 2020 Senior Notes.

Effective tax rate(37.1)% 420.4% (51.0)% (810.5)%

The effective income tax rate was (37.1)% and 420.4%$12.0 million for the three months ended March 31, 20172018 as we revised our estimates of foreign earnings and 2016, respectively. profits related to the mandatory repatriation tax.
The effectiveprovisional amounts above were based upon the estimates of (i) temporary differences at the end of the upcoming tax year, (ii) the timing the temporary differences are expected to reverse, (iii) foreign earnings and profits, and (iv) foreign income taxes. The assessment is incomplete as of March 31, 2018. As our assessment is ongoing, these amounts may materially change as we revise our assumptions and estimates based on new information available to us, changes in our interpretations, additional guidance to be issued, and actions we may take as a result of the TCJA. We are still evaluating the full impact of other provisions of the TCJA, which may materially increase or decrease our income tax rate was (51.0)% and (810.5)%provision. The assessment is expected to be completed no later than the first quarter of fiscal year 2019.
In addition, as more fully described in Note 4, in connection with the impairment charge of SRS's goodwill, we recognized a tax benefit of $8.5 million related to the portion of deductible goodwill in Brazil for the three and six months ended March 31, 2017 and 2016, respectively. Our current effective income tax rate differs from the U.S. federal statutory rate of 35% primarily due to current period losses in the United States that require an additional valuation allowance and accordingly provide no benefit to the provision as well as an increase to indefinite lived deferred tax liabilities. This is partially offset by our earnings in foreign operations that are subject to a significantly lower tax rate than the U.S. statutory tax rate, driven primarily by our subsidiaries in Ireland.
The effective income tax rate is based upon the income for the year, the composition of the income in different countries, changes relating to valuation allowances for certain countries if and as necessary, and adjustments, if any, for the potential tax consequences, benefits or resolutions of audits or other tax contingencies. Our aggregate income tax rate in foreign jurisdictions is lower than our income tax rate in the United States. The majority of our income before provision for income taxes from foreign operations has been earned by subsidiaries in Ireland. Our effective tax rate may be adversely affected by earnings being lower than anticipated in countries where we have lower statutory tax rates and higher than anticipated in countries where we have higher statutory tax rates.
At March 31, 2017 and September 30, 2016, we had gross tax effected unrecognized tax benefits of $28.3 million and $27.3 million, respectively, which are included in other long-term liabilities. If these benefits were recognized, they would impact our effective tax rate. We do not expect a significant change in the amount of unrecognized tax benefits within the next 12 months.2018.

Similar to many companies in the software industry, we are involved in a variety of claims, demands, suits, investigations and proceedings that arise from time to time relating to matters incidental to the ordinary course of our business, including at times actions with respect to contracts, intellectual property, employment, benefits and securities matters. We have estimatedAt each balance sheet date we evaluate contingent liabilities associated with these matters in accordance with ASC 450 “Contingencies.” If the potential loss from any claim or legal proceeding is considered probable and the amount can be reasonably estimated, we accrue a liability for the estimated loss. Significant judgments are required for the determination of probableprobability and the range of the outcomes, and estimates are based only on the best information available at the time.

Guarantees and Other
We often include indemnification provisions in the customercontracts we enter with customers and business partner contracts.partners. Generally, these provisions require us to defend claims arising out of our products’ infringement of third-party intellectual property rights, breach of contractual obligations and/or unlawful or otherwise culpable conduct. The indemnity obligations generally cover damages, costs and attorneys’ fees arising out of such claims. In most, but not all cases, our total liability under such provisions is limited to either the value of the contract or a specified, agreed upon amount. In some cases, our total liability under such provisions is unlimited. In many, but not all cases, the term of the indemnity provision is perpetual. While the maximum potential amount of future payments we could be required to make under all the indemnification provisions is unlimited, we believe the estimated fair value of these provisions is minimal due to the low frequency with which these provisions have been triggered.
We indemnify our directors and officers to the fullest extent permitted by Delaware law, which provides among other things, indemnification to directors and officers for expenses, judgments, fines, penalties and settlement amounts incurred by such persons in their capacity as a director or officer of the company, regardless of whether the individual is serving in any such capacity at the time the liability or expense is incurred. Additionally, in connection with certain acquisitions, we have agreed to indemnify the former officers and members of the boards of directors of those companies, on similar terms as described above, for a period of six years from the acquisition date. In certain cases, we purchase director and officer insurance policies related to these obligations, which fully cover the six yearsix-year period. To the extent that we do not purchase a director and officer insurance policy for the full period of any contractual indemnification, and such directors and officers do not have coverage under separate insurance policies, we would be required to pay for costs incurred, if any, as described above.

17. Segment and Geographic Information
During the first quarter of fiscal year 2018, we commenced a reorganization of our segment reporting structure to allow our Chief Operating Decision Maker ("CODM") greater focus on implementing strategic initiatives and identifying future investment opportunities. During the second quarter of fiscal year 2018, we established our Automotive business as a separate operating segment. Additionally, we moved our Dragon TV business from our Mobile operating segment into our Enterprise operating segment to consolidate our telecommunications market resources. Finally, our SRS business and our Devices business, originally included within our Mobile operating segment, are now presented within our Other segment. As a result, segment information for the following four reportable segments: Healthcare, Mobile, Enterprise,three and Imaging.six months ended March 31, 2018 and 2017 has been recast to reflect the new segment reporting structure.
Our CODM regularly reviews segment revenues and segment profits for performance evaluation and resources allocation.

OVERVIEW
Business Overview
We are a leading provider of voice recognitionpioneer and natural language understanding solutions.leader in conversational and cognitive artificial intelligence (AI) innovations that bring intelligence to everyday work and life. Our solutions and technologies can understand, analyze and respond to human language to increase productivity and amplify human intelligence. Our solutions are used by businesses in the healthcare, mobile, consumer, enterprise customer service,automotive, financial services, telecommunication and imaging markets.travel industries, among others. We are seeing several trends in our markets, including (i) the growing adoption of cloud-based, connected services and highly interactive mobile applications, (ii) deeper integration of virtual assistant capabilities and services, and (iii) the continued expansion of our core technology portfolio fromincluding speech recognition, to natural language understanding, semantic processing, domain-specific reasoning, dialog management capabilities, artificial intelligence, and biometric speaker authentication. We report our business in five segments, Healthcare, Enterprise, Automotive, Imaging and Other.
Confronted by dramatic increases in electronic information, consumers, business personnel and healthcare professionals must use a variety of resources to retrieve information, transcribe patient records, conduct transactions and perform other job-related functions. We believe that the power of our solutions can transform the way people use the Internet, telecommunications systems, electronic medical records ("EMR"), wireless and mobile networks and related corporate infrastructure to conduct business.BusinessTrends
Healthcare.  TrendsCustomers in our healthcare business include growing customer preference for hosted solutions and subscription-based license models and increased use of mobile devices to access healthcare systems and create clinical

documentation within electronic health record systems. In addition, wesegment are experiencing growing demand for integrated solutions, combining our Dragon Medical and hosted transcription offerings. The volume processed in our hosted transcription services has continued to erode as customers adoptbroadly implementing electronic medical record systems and are working to improve clinical documentation, to improve quality of care, to minimize physician burnout and to integrate quality measures and to aid reimbursement. These trends are driving a shift towards more integrated solutions that combine both Dragon Medical and transcription services. Recently, higher demand for more integrated solutions have offset declines in legacy, hosted

transcription services. Additionally, we have been able to capitalize on healthcare providers’ shift towards hosted, or cloud-based solutions, and away from perpetual licenses, by adding new innovations to our Dragon Medical solutions. This decline has been partially offset by new customer wins and the increased sale of integratedcloud solutions of our transcription and Dragon Medical offerings. We have also experienced declines in our Dragon Medical perpetual license revenue as customers shift toward Dragon Medical cloud offerings. These cloud offerings are enabling the expansion of our Dragon Medical solutions to includeincluding new clinical language understanding and artificial intelligence innovations, providing real time queriesArtificial Intelligence ("AI") capabilities designed to the physicianincrease productivity and improve clinical documentation at the point of care. We believe an important trend in the healthcare market is the desire to improve efficiency in the codingcare and revenue cycle management process. Our solutions reduce costs by increasing automation of this important workflow and also enable hospitals to improve documentation used to support billings. The industry’s shift in international classification of diseases ("ICD") from ICD-9 to ICD-10, together with evolving reimbursement reform that is increasingly focused on clinical outcomes, has increased the complexity of the clinical documentation and coding processes. This shift is reinforcing our customers’ desire for improved efficiency. We are investing to expand our product set to address the various opportunities, including deeper integration with our clinical documentation solutions; investing in our cloud-based products and operations; entering new and adjacent markets such as ambulatory care; and expanding our international capabilities.

within existing electronic medical work flow.
Mobile.Enterprise.   Trends in our mobile business include automotive original equipment manufacturers ("OEM") differentiating their offerings by using voice and contentConsumer demand for 24/7, multi-channel access to provide an enhanced experience for drivers; consumer electronics companies and cable operators competing to develop virtual assistant technologies forcustomer service from the home; geographic expansion of our mobile operator services; and the adoption of our technology on a broadening scope of devices, such as televisions, set-top boxes, and third-party applications. The more powerful capabilities within automobiles and mobile devices require us to supply a broader portfolio of specialized virtual assistants and connected services providing voice recognition, content integration, text-to-speech, and natural language understanding capabilities. We continued to see increasedbusinesses they interact with is driving demand for our enhanced offerings that combined speech and natural language understanding technology with artificial intelligence particularly from large automotive OEMs for our embedded and connectedAI-powered omni-channel engagement solutions. We are continuing to see a decline in our devices revenue resulting from the consolidation of the device market to a small number of customers as well as increased competition in voice recognition and natural language solutions and services sold to device OEMs. We continue to see demand involving the sale and delivery of both software and non-software related services, as well as products to help customers define, design and implement increasingly robust and complex custom solutions such as virtual assistants. We continue to see an increasing proportion of revenue from on-demand and transactional arrangements as opposed to traditional perpetual licensing of our Mobile products and solutions. Although this has a negative impact on near-term revenue, we believe this model will build more predictable revenues over time. We are investing in the expansion of the cloud capabilities and content of our automotive solutions; machine learning technologies, expansion across the Internet of Things in our devices solutions; and go-to market strategies with mobile operators.

Enterprise.  Trends in our enterprise business include increasing interest in the use of mobile applications and web sites to access customer care systems and records, voice-based authentication of users, increasing interest in coordinating actions and data across customer care channels, and the ability of a broader set of hardware providers and systems integrators to serve the market. In addition, for large enterprise businesses around the world, customer service interactions are accelerating toward more pervasive digital engagement across web, mobile and social platforms. In order to acquire and retain customers, enterprises need to be able to provide a customer service experience when and how the customer desires. This is creating a growing market opportunity for our omni-channel enterprise solutions, and with the acquisition of TouchCommerce, Inc., which closed during the fourth quarter of fiscal year 2016, we will be able to provide an end-to-end engagement platform that merges intelligent self-service with assisted service to increase customer satisfaction, strengthen customer loyalty and improve business results. In fiscal year 2016, revenues and bookings from on-demand solutions continued to increase, as a growing proportion of customers choose our cloud-based solutions for call center, web and mobile customer care solutions. We expect these trends to continue in fiscal year 2017. We are investing to extendenhance our technology capabilities with intelligent self-service and artificial intelligence for customer service;service, and to extend the market for our on-demand omni-channel enterprise solutions into international markets;markets, expand our sales and solutions for voice biometrics;biometrics, and expand our on-premise productcore products and services portfolio.

Automotive. We established the Automotive segment as a stand-alone segment this quarter reflecting growing demand for our Automotive solutions and our desire to optimize our opportunity in this expanding market. Previously, our Automotive business was reported as part of our Mobile segment. Demand for our embedded and cloud-based automotive solutions is being driven by the growth in personalized, automotive virtual assistants and connected services for cars and by auto manufacturers' desire to create a branded and personalized experience, capable of integrating and intelligently managing customers’ personal smart phone and home device preferences and technologies.
Imaging.The imaging market is evolving to include more networked solutions to multi-function printing ("MFP") devices, as well as more mobile access to those networked solutions, and away from packaged software. We are investing to merge the scan and print technology platforms to improve mobile access to our solutions and technologies;technologies, expand our distribution channels and embedding relationships;embedded relationships, and expand our language coverage for optical character recognition ("OCR") in order to drive a more comprehensive and compelling offering to our partners.

Other. The Other segment includes our Subscriber Revenue Services ("SRS") business and our Devices business. Our SRS business provides value-added services to mobile operators in emerging markets, primarily in India and Brazil. Our Devices business provides speech recognition solutions and predictive text technologies to handset devices.
As more fully described in Note 4 to the accompanying condensed consolidated financial statements, for the three and six months ended March 31, 2018, we recognized a goodwill impairment charge of $102.8 million related to SRS as a result of lowering our long-term projections of the business during the second quarter of fiscal year 2018 due to the recent market disruptions in India and Brazil. These markets have experienced recent and dramatic disruption as a result of accelerated change in competition and business models for our SRS mobile operator customers. Specifically, the rapid shift away from a model where voice, data and text are offered separately toward unlimited bundled services at considerably lower costs has significantly reduced mobile operators’ demand for our services. This reduced demand materially impacts our future expectations for SRS revenues. As a result, executive management performed an updated strategic assessment and reduced the long-term growth rates and profitability contemplated in SRS's multi-year operating plan. We concluded that these financial results coupled with the accelerated market shifts being experienced in the industry were factors that represented impairment indicators, triggering a review of goodwill and indefinite-lived intangible assets for impairment during the second quarter of fiscal 2018.
Additionally, we recognized a $35.1 million goodwill impairment related to our Devices business, which has been declining due to the ongoing consolidation of our handset manufacturer customer base and continued erosion of our penetration of the remaining market. While the business has been performing in line with our expectations, the reorganization, as more fully described in Note 17 to the accompanying condensed consolidated financial statements, triggered an assessment for the goodwill assigned to the business.
Key Metrics
In evaluating the financial condition and operating performance of our business, management focuses on revenues, net income, gross margins, operating margins, cash flow from operations, and changes in deferred revenue. A summary of these key financial metrics is as follows:
Forfor the six months ended March 31, 2017,2018, as compared to the six months ended March 31, 2016:2017, is as follows:
Total revenues increased by $22.4$28.6 million to $987.2$1,015.9 million;
Net loss increased by $38.6$53.1 million to a loss of $57.7$110.8 million;
Gross margins decreased by 0.51.2 percentage points to 56.9%55.7%;
Operating margins decreased by 1.017.5 percentage points to 5.6%(11.9)%; and
Cash provided by operating activities decreased $50.7by $55.0 million to $250.3$195.4 million.

As of March 31, 2017,2018, as compared to March 31, 2016:2017:
Total deferred revenue increased 7.2%by 10.0% from $748.5$802.4 million to $802.4$882.7 million, primarily driven primarily by the continued growth of our hosting solutions, most notably for our automotiveAutomotive connected services in our Mobile segment.and Healthcare bundled offerings.
In addition to the above key financial metrics, we also focus on certain operating metrics. A summary of these key operating metrics for the quarterthree months ended March 31, 2017,2018, as compared to the quarterthree months ended March 31, 2016,2017, is as follows:
Net new bookings increased 30.8%decreased by 8% from one year ago to $410.4 million. The net new bookings growth benefited from strong bookings performance$376.6 million, primarily due to declines in our HealthcareAutomotive and MobileImaging segments.
Bookings represent the estimated gross revenue value of transactions at the time of contract execution, except for maintenance and support offerings. For fixed price contracts, the bookings value represents the gross total contract value. For contracts where revenue is based on transaction volume, the bookings value represents the contract price multiplied by the estimated future transaction volume during the contract term, whether or not such transaction volumes are guaranteed under a minimum commitment clause. Actual results could be different than our initial estimate. The maintenance and support bookings value represents the amounts the customer is invoiced in the period. Because of the inherent estimates required to determine bookings and the fact that the actual resultant revenue may differ from our initial bookings estimates, we consider bookings one indicator of potential future revenue and not as an arithmetic measure of backlog.
Net new bookings represents the estimated revenue value at the time of contract execution from new contractual arrangements or the estimated revenue value incremental to the portion of value that will be renewed under pre-existing arrangements;arrangements.
Recurring revenue represented 73.3%71% and 69.0%74% of total revenue for sixthree months ended March 31, 20172018 and March 31, 2016,2017, respectively. Recurring revenue represents the sum of recurring hosting, product and licensing, hosting, and maintenance and support revenues as well as the portion of professional services revenue delivered under ongoing contracts. Recurring product and licensing revenue comprises term-based and ratable licenses as well as revenues from royalty arrangements;arrangements.
Annualized line run-rate in our on-demand healthcare solutions decreased 8%by 33% from onea year ago to approximately 4.73.2 billion lines per year. The decrease was primarily due to the continued erosion in our transcription services.services and the impact of the 2017 Malware Incident, as defined below. The annualized line run-rate is determined using billed equivalent line counts in a given quarter, multiplied by four; andfour.
Estimated three-year value of total on-demand contracts atas of March 31, 2017 increased 19%2018 decreased by 9% from onea year ago to approximately $2.6$2.3 billion. The increasedecrease was primarily due to the continued erosion in our Enterprise omni-channel solutionstranscription services, and the impact of the 2017 Malware Incident, offset in part by growth in our Dragon Medical cloud offerings.and Automotive solutions. We determine this value as of the end of the period reported, by using our estimate of three years of anticipated future revenue streams under signed on-demand contracts then in place, whether or not they are guaranteed through a minimum commitment clause. Our estimate is based on assumptions used in evaluating the contracts and determining sales compensation, adjusted for changes in estimated launch dates, actual volumes achieved, and other factors deemed relevant. For contracts with an expiration date beyond three years, we include only the value expected within three years. For other contracts, we assume renewal consistent with historic renewal rates unless there is a known cancellation. Contracts are

generally priced by volume of usage and typically have no or low minimum commitments. Actual revenue could vary from our estimates due to factors such as cancellations, non-renewals or volume fluctuations.
Cybersecurity & Data Privacy Matters
On June 27, 2017, Nuance was a victim of the global NotPetya malware incident (the “2017 Malware Incident”). The NotPetya malware affected certain Nuance systems, including systems used by our healthcare customers, primarily for transcription services, as well as systems used by our imaging division to receive and process orders. For fiscal year 2017, we estimate that we lost approximately $68.0 million in revenues, primarily in our Healthcare segment, due to the service disruption and the reserves we established for customer refund credits related to 2017 Malware Incident. Additionally, we incurred incremental costs of approximately $24.0 million for fiscal year 2017 as a result of our remediation and restoration efforts, as well as incremental amortization expenses. Although the direct effects of the 2017 Malware Incident were remediated during fiscal year 2017, as explained below, the 2017 Malware Incident had a continued effect on our results of operations in the first half of fiscal year 2018 including contributing to: a year-over-year decline in the annualized line run-rate in our on-demand healthcare solutions and in the estimated three-year value of on-demand contracts; a year-over-year decline in hosted revenue and an increase in restructuring and other charges. In addition, we expect to expend additional resources during the remainder of fiscal year 2018 and beyond to continue to enhance and upgrade information security.

In addition, in December 2017, an unauthorized third party illegally accessed certain reports hosted on a Nuance transcription platform. This incident was limited in scope to records of approximately 45,000 individuals and was isolated to a single transcription platform that was promptly shutdown. Customers using that platform were notified of the incident and were migrated to our eScription transcription platforms. We also notified law enforcement authorities and have cooperated in their investigation into the matter. The law enforcement investigation resulted in the identification of the third party, and the accessed reports have been recovered. This incident did not have a material effect on our financial results for the six months ended March 31, 2018 and is not expected to have a material effect on our financial results for future periods. Future cybersecurity or data privacy incidents could have a material adverse effect on our results of operations. See “Risk Factors - Cybersecurity and data privacy incidents or breaches may damage client relations and inhibit our growth.”

As more fully described in Note 14 to the accompanying condensed consolidated financial statements, as a result of the Tax Cuts and Jobs Act ("TCJA"), we remeasured certain deferred tax assets and liabilities at the lower rates and recorded approximately $87.0 million of tax benefits for the six months ended March 31, 2018, which also reflected an expense of $10.0 million for the three months ended March 31, 2018 as we revised our estimates of the timing and amounts of the temporary differences. Additionally, we recorded a $2.0 million provision for the deemed repatriation of foreign cash and earnings for the six months ended March 31, 2018, which also reflected a benefit of $12.0 million for the three months ended March 31, 2018 as we revised our estimates of foreign earnings and profits related to the mandatory repatriation tax.

The effective incomeIn addition, as more fully described in Note 4 to the condensed consolidated financial statements, in connection with the impairment charge of SRS's goodwill, we recognized a tax rate was (37.1)% and (51.0)%benefit of $8.5 million related to the portion of deductible goodwill in Brazil for the three and six months ended March 31, 2017, respectively. Our current effective income tax rate differs from the U.S. federal statutory rate of 35% primarily due to current period losses in the United States that require an additional valuation allowance and accordingly provide no benefit to the provision as well as an increase to indefinite lived deferred tax liabilities. This is partially offset by our earnings in foreign operations that are subject to a significantly lower tax rate than the U.S. statutory tax rate, driven primarily by our subsidiaries in Ireland.
The effective income tax rate is based upon the income for the year, the composition of the income in different countries, changes relating to valuation allowances for certain countries if and as necessary, and adjustments, if any, for the potential tax consequences, benefits or resolutions of audits or other tax contingencies. Our aggregate income tax rate in foreign jurisdictions is lower than our income tax rate in the United States. The majority of our income before provision for income taxes from foreign operations has been earned by subsidiaries in Ireland. Our effective tax rate may be adversely affected by earnings being lower than anticipated in countries where we have lower statutory tax rates and higher than anticipated in countries where we have higher statutory tax rates.2018.
SEGMENT ANALYSIS
We operate in,During the first quarter of fiscal year 2018, we commenced a reorganization of our segment reporting structure to allow our Chief Operating Decision Maker ("CODM") greater focus on implementing strategic initiatives and report financialidentifying future investment opportunities. During the second quarter of fiscal year 2018, we established our Automotive business as a separate operating segment. Additionally, we moved our Dragon TV business from our Mobile operating segment into our Enterprise operating segment to consolidate our telecommunications market resources. Finally, our SRS business and our Devices business, originally included within our Mobile operating segment, are now presented within our Other segment. As a result, segment information for the following four reportable segments: Healthcare, Mobile, Enterprise,three and Imaging. Segment profit is an important measure used for evaluating performancesix months ended March 31, 2018 and for decision-making purposes and reflects2017 has been recast to reflect the direct controllable costs of eachnew segment together with an allocation of sales and corporate marketing expenses, and certain research and development project costs that benefit multiple product offerings. Segment profit represents income from operations excluding stock-based compensation, amortization of intangible assets, acquisition-related costs, net, restructuring and other charges, net, costs associated with intellectual property collaboration agreements, other expense, net and certain unallocated corporate expenses. We believe that these adjustments allow for more complete comparisons to the financial results of the historical operations.

Healthcare segment revenue decreased $5.9increased by $22.7 million, for the three months ended March 31, 2017, as comparedor 9.5%, primarily due to the three months ended March 31, 2016. Producthigher revenue from Dragon Medical cloud-based solutions and licensing revenue decreased $5.3 million drivenEHR implementation and optimization services, offset by in part by lower revenue from our Dragon Medical perpetualtranscription services revenue due to the continued erosion, and the negative impact of the 2017 Malware Incident.
Enterprise segment revenue decreased by $9.4 million, or 7.7%, primarily due to lower contact center license sales as we transitionand services revenue, and lower volume through our legacy inbound and outbound on-demand solutions.

Automotive segment revenue increased by $7.3 million, or 11.7%, primarily due to higher revenues from perpetual to cloud offerings. Professional servicesroyalties and hosting revenue decreased $0.3 million due tosolutions driven by continued erosion in our transcription services partially offset by strong revenue growth in our Dragon Medical cloudconnected services.

Mobile segment revenue increased $8.4 million for the three months ended March 31, 2017, as compared to the three months ended March 31, 2016. Professional services and hosting revenue increased $8.4 million driven primarily by a continued trend toward cloud-based services in our automotive solutions and strength in our mobile operator services.

Imaging segment revenues decreased $3.7by $4.1 million, or 7.8%, primarily due to lower revenue from our scanning and print management solutions.
Other segment revenue decreased by $9.2 million, or 25.8%, primarily due to declines in both SRS and Devices. The decline in SRS was primarily due to the recent market disruptions in India and Brazil. These markets have experienced recent and dramatic disruptions as a result of accelerated change in competition and business models for our SRS mobile operator customers, which has reduced demand for our services. The decline in our Devices business was primarily due to the three months endedongoing consolidation of our handset manufacturer customer base, as well as continued erosion of our penetration of the remaining market.
Six Months Ended March 31, 2017, as2018 compared to the three months ended March 31, 2016, primarily driven by lower sales of our MFP products.

However, we will assess our operating and investing cash flow requirements and the borrowing economics in the capital markets at that time to determine the appropriate funding source.
We believe our current cash and cash equivalents, marketable securities, and cash flow from operations are sufficient to meet our operating needs for at least the next twelve months.

We account separately for the liability and equity components of the 1.25% 2025 Debentures in accordance with authoritative guidance for convertible debt instruments that may be settled in cash upon conversion.

We may not redeem the 1.25% 2025 Debentures prior to the maturity date. If we undergo a fundamental change or non-stock change of control (as described in the indenture for the 1.25% 2025 Debentures) prior to maturity, holders will have the option to require us to repurchase all or any portion of their debentures for cash at a price equal to 100% of the principal amount of the 1.25% 2025 Debentures to be purchased plus any accrued and unpaid interest, including any additional interest to, but excluding, the repurchase date. As of March 31, 2017, none of the conversion criteria were met for the 1.25% 2025 Debentures. If the conversion criteria were met, we could be required to repay all or some of the aggregate principal amount in cash prior to the maturity date.
1.50% Convertible Debentures due 2035
In June 2015, we issued $263.9 million in aggregate principal amount of 1.50% Senior Convertible Debentures due in 2035 (the “1.5% 2035 Debentures”) in exchange for $256.2 million in aggregate principal amount of our 2031 Debentures. The 1.5%

2035 Debentures were issued at 97.09% of the principal amount, which resulted in a discount of $7.7 million. The 1.5% 2035 Debentures bear interest at 1.50% per year, payable in cash semi-annually in arrears. The 1.5% 2035 Debentures mature on November 1, 2035, subject to the right of the holders to require us to redeem the 1.5% 2035 Debentures on November 1, 2021, 2026, or 2031. The 1.5% 2035 Debentures are general senior unsecured obligations and rank equally in right of payment with all of our existing and future unsecured, unsubordinated indebtedness and senior in right of payment to any indebtedness that is contractually subordinated to the 1.5% 2035 Debentures. The 1.5% 2035 Debentures will be effectively subordinated to indebtedness and other liabilities of our subsidiaries. The initial conversion price is approximately $23.26 per share. At issuance, we allocated $208.6 million to long-term debt, and $55.3 million has been recorded as additional paid-in capital, which is being amortized to interest expense using the effective interest rate method through November 2021. As of March 31, 2017 and September 30, 2016, none of the conversion criteria were met for the 1.5% 2035 Debentures. If the conversion criteria were met, we could be required to repay all or some of the aggregate principal amount in cash prior to the maturity date.
Revolving Credit Facility
In April 2016, we entered into a credit agreement that provides for a $242.5 million revolving credit line, including letters of credit (together, the “Revolving Credit Facility”). The Revolving Credit Facility matures on April 15, 2021. As of March 31, 2017, issued letters of credit in the aggregate amount of $4.5 million were treated as issued and outstanding when calculating the borrowing availability under the Revolving Credit Facility. As of March 31, 2017, we had $238.0 million available for additional borrowing under the Revolving Credit Facility. Any amounts outstanding under the Revolving Credit Facility will bear interest, at either (i) LIBOR plus an applicable margin of 1.50% or 1.75%, or (ii) the alternative base rate plus an applicable margin of 0.50% or 0.75%. The Revolving Credit Facility is secured by substantially all assets of ours and our Subsidiary Guarantors. The Revolving Credit Facility contains customary affirmative and negative covenants and conditions to borrowing, as well as customary events of default.financial statements.
Share Repurchase Program
On April 29, 2013, our Board of Directors approved a share repurchase program for up to $500.0 million of our outstanding shares of common stock.million. On April 29, 2015, our Board of Directors approved an additional $500.0 million under our share repurchase program. In March 2017, in connection with the issuance of our 1.25% 2025 Debentures, we used a portion of the net proceeds to repurchase 5.8 million shares of our common stock for $99.1 million under the approved program. Since the commencement of the program, we have repurchased 46.5 million shares for $806.6 million. These shares were retired upon repurchase. Approximately $193.4 million remained available for share repurchases as of March 31, 2017 pursuant to our share repurchase program. Under the terms of the share repurchase program, we have the ability to repurchase shares from time to time through a variety of methods, which may include open market purchases, privately negotiated transactions, block trades, accelerated stock repurchase transactions, or any combination of such methods. The share repurchase program does not require us to acquire any specific number of shares and may be modified, suspended, extended or terminated by us at any time without prior notice. The timing and the amount of any purchases will be determined by management based on an evaluation of market conditions, capital allocation alternatives, and other factors.
There were no share repurchases for the six months ended March 31, 2018. For the six months ended March 31, 2017, we repurchased 5.8 million shares of our common stock for $99.1 million under the program. Since the commencement of the program, we have repurchased an aggregate of 46.5 million shares for $806.6 million. The amount paid in excess of par value is recognized

in additional paid in capital. Shares were retired upon repurchase. As of March 31, 2018, approximately $193.4 million remained available for future repurchases under the program.

CRITICAL ACCOUNTING POLICIES JUDGMENTS AND ESTIMATES
The preparation of financial statements in conformity with U.S. generally accepted accounting principles ("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 dates of the financial statements, and the reported amounts of revenue and expenses during the reporting periods. On an ongoing basis, we evaluate our estimates, assumptions and judgments, including those related to:

revenue recognition; allowance for doubtful accounts and sales returns; accounting for deferred costs; accounting for internally developed software; the valuation of goodwill and intangible assets; accounting for business combinations, including contingent consideration; accounting for stock-based compensation; accounting for derivative instruments; accounting for income taxes and related valuation allowances; and loss contingencies. Our management bases its estimates on historical experience, market participant fair value considerations, projected future cash flows and various other factors that are believed to be reasonable under the circumstances. Actual results could differ from these estimates.

RECENTLY ADOPTED AND ISSUED ACCOUNTING STANDARDS
Refer toSee Note 2 to the unauditedaccompanying condensed consolidated financial statements included in Item 1for a discussion of Part I of this Quarterly Report on Form 10-Q.the recently adopted and issued accounting standards.
Item 3.Quantitative and Qualitative Disclosures about Market Risk
We are exposed to market risk from changes in foreign currency exchange rates, interest rates and equity prices which could affect operating results, financial position and cash flows. We manage our exposure to these market risks through our regular operating and financing activities and, when appropriate, through the use of derivative financial instruments.
Exchange Rate Sensitivity
We are exposed to changes in foreign currency exchange rates. Any foreign currency transaction, defined as a transaction denominated in a currency other than the local functional currency, will be reported in the functional currency at the applicable exchange rate in effect at the time of the transaction. A change in the value of the functional currency compared to the foreign currency of the transaction will have either a positive or negative impact on our financial position and results of operations.
Assets and liabilities of our foreign entities are translated into U.S. dollars at exchange rates in effect at the balance sheet date and income and expense items are translated at average rates for the applicable period. Therefore, the change in the value of the U.S. dollar compared to foreign currencies will have either a positive or negative effect onmay impact our financial position and results of operations. Historically, our primary exposure has related to transactions denominated in the euro, British pound, Brazilian real, Canadian dollar, Japanese yen, Indian rupee and Hungarian forint.
A hypothetical change of 10% in appreciation or depreciation in foreign currency exchange rates from the quoted foreign currency exchange rates at March 31, 2017 would not have a material impact on our revenue, operating results or cash flows in the coming year.
Periodically, we enter into forward exchange contracts to hedge against foreign currencyexchange rate fluctuations. TheseAs of March 31, 2018, we had not designated any contracts mayas fair value or may not be designated as cash flow hedges for accounting purposes. We have in place a program which primarily uses forward contracts to offset the risks associated with foreign currency exposures that arise from transactions denominated in currencies other than the functional currencies of our worldwide operations.hedges. The program is designed so that increases or decreases in our foreign currency exposures are offset by gains or losses on the foreign currency forward contracts. The outstanding contracts are not designated as cash flow hedges and generally are for periods less than 90 days. TheAs of March 31, 2018, the notional contract amount of outstanding foreign currency exchange contracts not designated as cash flow hedges was $69.3 million at March 31, 2017. Based on the nature of the transactions for which the contracts were purchased, a hypothetical change of 10% in exchange rates would not have a material impact on our financial results.$78.0 million.
Interest Rate Sensitivity
We are exposed to interest rate risk as a result of our cash and cash equivalents and marketable securities.
At March 31, 2017,2018, we held approximately $831.2$648.7 million of cash and cash equivalents and marketable securities primarily consisting of cash, money-market funds, bank deposits and a separately managed investment portfolio. Assuming a one percentage point increasechange in interest rates, our interest income on our investments classified as cash and cash equivalents and marketable securities would increasechange by approximately $7.1$6.4 million per annum, based on the balances as of March 31, 2017 reported balances of our investment accounts.2018.
At March 31, 2017,2018, we had no outstanding debt exposedsubject to variable interest rates.

2031 Debentures, 1.5% 2035 Debentures, 1.0% 2035 Debentures and 1.25% 2025Convertible Debentures
The fair values of our 2031 Debentures, 1.5% 2035 Debentures, 1.0% 2035 Debentures and 1.25% 2025 Debenturesconvertible debentures are dependent on the price and volatility of our common stock as well as movements in interest rates. The fair market values of these debentures will generally increase as the market price of our common stock increases and will decrease as the market price of our common stock decreases. The fair market values of these debentures will generally increase as interest rates fall and decrease as interest rates rise. The market value and interest rate changes affect the fair market values of these debentures, but do not impact our financial position, results of operations or cash flows due to the fixed nature of the debt obligations. However, increases in the value of our common stock above the stated trigger price for each issuance for a specified period of time may provide the holders of these debentures the right to convert each bond using a conversion ratio and payment method as defined in the debenture agreement.
Our debentures trade in the financial markets, and

Item 4.Controls and Procedures
Evaluation of Disclosure Controls and Procedures
Our management is responsible for establishing and maintaining a system of disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934 (the “Exchange Act”)) designed to ensure that information we are required to disclose in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by an issuer in the reports that it files or submits under the Exchange Act is accumulated and communicated to the issuer’s management, including its principal executive officer or officers and principal financial officer or officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.
We have evaluated the effectiveness of the design and operation of our disclosure controls and procedures under the supervision of, and with the participation of, management, including our Chief Executive Officer and Chief Financial Officer, as of the end of the period covered by this report. Based on that evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures are effective to meet the requirements of Rules 13a-15(f) and 15d-15(f) under the Exchange Act.
Changes in Internal Control Over Financial Reporting
There were no material changes to our internal controls over financial reporting as defined in the Exchange Act Rules 13a-15(f) and 15d-15(f) identified in connection with the evaluation that occurred during the fiscal quarter covered by this Quarterly Report on Form 10-Q that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Item 1.Legal Proceedings
This information is included in Note 15, Commitments and Contingencies, in the accompanying notes to unaudited consolidated financial statements and is incorporated herein by reference from Item 1 of Part I.

Item 1A.Risk Factors
Risk Factors
You should carefully consider the risks described below when evaluating our company and when deciding whether to invest in our company. The risks and uncertainties described below are not the only ones we face. Additional risks and uncertainties not presently known to us or that we do not currently believe are important to an investor may also harm our business operations. If any of the events, contingencies, circumstances or conditions described below actually occurs, our business, financial condition or our results of operations could be seriously harmed. If that happens, the trading price of our common stock could decline, and you may lose part or all of the value of any of our shares held by you.

Risks Related to Our Business
The markets in which we operate are highly competitive and rapidly changing and we may be unable to compete successfully.
There are a number of companies that develop or may develop products that compete in our targeted markets. The markets for our products and services are characterized by intense competition, evolving industry and regulatory standards, emerging business and distribution models, disruptive software and hardware technology developments, short product and service life cycles, price

sensitivity on the part of customers, and frequent new product introductions, including alternatives withfor certain of our products that offer limited functionality available at significantly lower costs or free of charge. Within voice recognition and natural language understanding, we compete primarily with Amazon, Google, iFlyTek andas well as other smaller providers. Within healthcare,In our Healthcare business we compete primarily with M*Modal, Optum, 3M and other smaller providers. Within imaging,In our Automotive business we compete, or may in the future compete, with Amazon, Google, iFlyTek and Microsoft as well as with other, smaller vendors particularly in China. In our Imaging business we compete primarily with ABBYY and Adobe. In our enterprise business,Also, some of our partners such as Avaya, Canon, Cisco, and Genesys develop and market products that might be considered substitutes for our solutions. In addition, a number of smaller companies in voice recognition, natural language understanding, text input and imaging produce technologies or products that are in some markets competitive with our solutions. Current and potential competitors have established, or may establish, cooperative relationships among themselves or with third parties to increase the ability of their technologies to address the needs of our prospective customers. Furthermore, there has been a trend toward industry consolidation in our markets for several years. We expect this trend to continue as companies attempt to strengthen or hold their market positions in an evolving industry and as companies are acquired or are unable to continue operations.
The competition in these markets could adversely affect our operating results by reducing the volume of the products we license or the prices we can charge. Some of our current or potential competitors, such as 3M, Adobe, Amazon, Google and Google,Microsoft, have significantly greater financial, technical and marketing resources than we do. These competitors may be able to respond more rapidly than we can to new or emerging technologies or changes in customer requirements. They may also devote greater resources to the development, promotion and sale of their products than we do, and in certain cases may be able to include or combine their competitive products or technologies with other of their products or technologies in a manner whereby the competitive functionality is available at lower cost or free of charge within the larger offering. To the extent they do so, market acceptance and penetration of our products, and therefore our revenue and bookings, may be adversely affected. Our success will depend substantially upon our ability to enhance our products and technologies and to develop and introduce, on a timely and cost-effective basis, new products and features that meet changing customer requirements and incorporate technological enhancements. If we are unable to develop new products and enhance functionalities or technologies to adapt to these changes, or if we are unable to realize synergies among our acquired products and technologies, our business will suffer.
Our operating results may fluctuate significantly from period to period, and this may cause our stock price to decline.
Our revenue, bookings and operating results have fluctuated materially in the past and are expected to continue to fluctuate in the future. Given these fluctuations, we believe that quarter to quarter comparisons of revenue, bookings and operating results are not necessarily meaningful ornor an accurate indicator of our future performance. These fluctuations may cause our results of operations to not meet the expectations of securities analysts or investors. If this occurs, the price of our stock would likely decline. Factors that contribute to fluctuations in operating results include:
volume, timing and fulfillment of customer orders and receipt of royalty reports;
the pace of the transition to an on-demand and transactional revenue model;
slowing sales by our channel partners to their customers;
customers delaying their purchasing decisions in anticipation of new versions of our products;
contractual counterparties are unable to, or do not, meet their contractual commitments to us;
introduction of new products by us or our competitors;
cybersecurity or data breaches perpetrated by hackers or other third parties;
seasonality in purchasing patterns of our customers;

reduction in the prices of our products in response to competition, market conditions or contractual obligations;
returns and allowance charges in excess of accrued amounts;
timing of significant marketing and sales promotions;
impairment of goodwill or intangible assets;
the pace of the transition to an on-demand and transactional revenue model;
delayed realization of synergies resulting from our acquisitions;
accounts receivable that are not collectible and write-offs of excess or obsolete inventory;
increased expenditures incurred pursuing new product or market opportunities;
general economic trends as they affect retail and corporate sales; and
higher than anticipated costs related to fixed-price contracts with our customers.customers; and
general economic trends as they affect the customer bases into which we sell.
Due to the foregoing factors, among others, our revenue, bookings and operating results are difficult to forecast. Our expense levels are based in significant part on our expectations of future revenue, and we may not be able to reduce our expenses quickly to respond to a shortfallnear-term shortfalls in projected revenue. Therefore, our failure to meet revenue expectations would seriously harm our operating results, financial condition and cash flows.

A significant portion of our revenue and bookings are derived, and a significant portion of our research and development activities are based, outside the United States. Our results could be harmed by economic, political, regulatory, foreign currency fluctuations and other risks associated with these international regions.
Because we operate worldwide, our business is subject to risks associated with doing business internationally. We anticipate that revenue and bookings from international operations could increase in the future. Most of our international revenue and bookings are generated by sales in Europe and Asia. In addition, some of our products are developed outside the United States and we have a large number of employees in India that provide development and transcription services. We also have a large number of employees in Canada, Germany and the United Kingdom that provide professional services. A significant portion of the development of our voice recognition and natural language understanding solutions is conducted in Canada and Germany, and a significant portion of our imaging research and development is conducted in Hungary and Canada. We also have significant research and development resources in Austria, Belgium, China, Italy, and the United Kingdom. In addition, we are exposed to changes in foreign currencies including the euro, British pound, Brazilian real, Canadian dollar, Japanese yen, Indian rupee and Hungarian forint. Changes in the value of foreign currencies relative to the value of the U.S. dollar could adversely affect future revenue and operating results. Accordingly, our future results could be harmed by a variety of factors associated with international sales and operations, including:
the impact on local and global economies of the United Kingdom leaving the European Union;
changes in foreign currency exchange rates or the lack of ability to hedge certain foreign currencies;
changes in a specific country's or region's economic conditions;

We recently hired a new Chief Executive Officer. If we encounter difficulties in the transition, our business could be negatively impacted.
Mark D. Benjamin became our Chief Executive Officer and a member of our Board of Directors late April 2018. Our future success will partly depend upon Mr. Benjamin’s ability, along with the ability of other senior management and other key employees, to effectively implement our business strategies. In addition, Mr. Benjamin may pursue changes in our strategy or business focus. Mr. Benjamin may require transition time to fully understand all aspects of our business as would be typical with any executive transition. If we have failures in any aspects of this transition, or new strategies implemented by our management team are not successful, our business could be harmed.
If we are unable to attract and retain key personnel, our business could be harmed.
If any of our key employees were to leave, we could face substantial difficulty in hiring qualified successors and could experience a loss in productivity while any successor obtains the necessary training and experience. OurFor example, we have recently undergone a chief executive officer transition with the retirement of Mr. Ricci as our Chief Executive Officer in March 2018 and the appointment of Mr. Benjamin as our new Chief Executive Officer in April 2018. In addition, two other members of our senior management team have recently left the company. Although we have arrangements with some of our executive officers designed to promote retention, our employment relationships are generally at-will and we have had key employees leave in the past. We cannot assure you that one or more key employees will not leave in the future. We intend to continue to hire additional highly qualified personnel, including research and development and operational personnel, but may not be able to attract, assimilate or retain qualified personnel in the future. Any failure to attract, integrate, motivate and retain these employees could harm our business.

In response to our changing needs and input from our investors, we recently added a number of new directors to our Board of Directors and expect to add additional directors over the balance of fiscal year 2018. If the transition to these new directors is not effective, our business could be harmed.
In addition to his appointment as Chief Executive Officer, Mr. Benjamin was appointed to our Board of Directors. With this addition, three of the eight members of our Board of Directors have joined since December 2017. We expect to add additional members to our Board of Directors in the coming months and to reconstitute the membership of Board Committees as new directors are added to take advantage of the experience the new members bring to our Board of Directors. There can be no assurances that the new Board of Directors or its committees will function effectively and that there will not be any adverse effects on the business as a result of the significant changes on our Board of Directors.
We experienced a significant malware incident in the third quarter of fiscal year 2017, which had and continues to have a significant impact on our future results of operations and financial condition.
On June 27, 2017, Nuance was a victim of the global NotPetya malware incident (the “2017 Malware Incident”). The NotPetya malware affected certain Nuance systems, including systems used by our healthcare customers, primarily for transcription services, as well as systems used by our imaging division to receive and process orders. Our revenue and our operating results for fiscal year 2017 were negatively impacted by the 2017 Malware Incident. For fiscal year 2017, we estimate that we lost approximately $68.0 million in revenues, primarily in our Healthcare segment, due to the service disruption and the reserves we established for customer refund credits. Additionally, we incurred incremental costs of approximately $24.0 million for fiscal year 2017 as a result of our remediation and restoration efforts, as well as incremental amortization expenses. Although the direct effects of the 2017 Malware Incident were remediated during fiscal year 2017, the 2017 Malware Incident had a continued effect on our results of operations in the first and second quarters of fiscal year 2018, and our outlook for the remainder of fiscal year 2018 reflects both the residual effects of the incident and the additional resources we will need to invest on an ongoing basis to continuously enhance information security.
Cybersecurity and data privacy incidents or breaches may damage client relations and inhibit our growth.
The confidentiality and security of our information, and that of third parties, is critical to our business. Our services involve the transmission, use, and storage of customers’ and their customer’s confidential information. We were the victim of a cybercrime in the past, and future cybersecurity or data privacy incidents could have a material adverse effect on our results of operations and financial condition. While we maintain a broad array of information security and privacy measures, policies and practices, our networks may be breached through a variety of means, resulting in someone obtaining unauthorized access to our information, to information of our customers or their customers, or to our intellectual property; disabling or degrading service; or sabotaging systems or information. In addition, hardware, software, or applications we develop or procure from third parties may contain defects in design or manufacture or other problems that could unexpectedly compromise information security. Unauthorized parties may also attempt to gain access to our systems or facilities, or those of third parties with whom we do business, through fraud or other forms of deceiving our employees, contractors, and vendors. Because the techniques used to obtain unauthorized access, or to sabotage systems, change frequently and generally are not recognized until launched against a target, we may be unable to anticipate these techniques or to implement adequate preventative measures. We will continue to incur significant costs to continuously enhance our information security measures to defend against the threat of cybercrime. Any cybersecurity or data privacy incident or breach may result in:
loss of revenue resulting from the operational disruption;
loss of revenue or increased bad debt expense due to the inability to invoice properly or to customer dissatisfaction resulting in collection issues;
loss of revenue due to loss of customers;
material remediation costs to restore systems;
material investments in new or enhanced systems in order to enhance our information security posture;
cost of incentives offered to customers to restore confidence and maintain business relationships;
reputational damage resulting in the failure to retain or attract customers;
costs associated with potential litigation or governmental investigations;
costs associated with any required notices of a data breach;
costs associated with the potential loss of critical business data; and
other consequences of which we are not currently aware but will discover through the remediation process.

Our business is subject to a variety of domestic and international laws, rules, policies and other obligations regarding data protection.
We are subject to a complex array of federal, state and international laws relating to the collection, use, retention, disclosure, security and transfer of personally identifiable information and personal health information, with additional laws applicable in some jurisdictions where the information is collected from children. In many cases, these laws apply not only to transfers between unrelated third-parties but also to transfers between us and our subsidiaries. Many jurisdictions have passed laws in this area, and other jurisdictions are considering imposing additional restrictions. These laws continue to evolve and may be inconsistent from jurisdiction to jurisdiction. In April 2016, theThe European Commission adopted the European General Data Protection Regulation (the “GDPR”). The GDPR has, which will be in effect as of May 25, 2018. China adopted a two-year phase-in period.new cybersecurity law as of June 2017, and there is an increase in regulation of biometric data globally, which may include voiceprints. Complying with the GDPR and other emerging and changing requirements may cause us to incur substantial costs orand may require us to change our business practices. Noncompliance could result in penalties or significant legal liability, and could affect our ability to retain and attract customers.
Any failure by us, our customers, suppliers or other parties with whom we do business to comply with our privacy policy or with other federal, state or international privacy-related or data protection laws and regulations could result in proceedings against us by governmental entities or others. Any alleged or actual failure to comply with applicable privacy laws and regulations may:
cause our customers to lose confidence in our solutions;
harm our reputation;
expose us to litigation, regulatory investigations and liability;to resulting liabilities including reimbursement of customer costs, damages penalties or fines imposed by regulatory agencies; and
require us to incur significant expenses for remediation.

Interruptions or delays in service from data center hosting facilities could impair the delivery of our services and harm our business.
We currently serve our customers from our, third-party, data center hosting facilities we directly manage and from third-party public cloud facilities. Any damage to, or failure of, the systems that serve our customers in whole or in part, could result in interruptions in our service. Interruptions in our service may reduce our revenue, cause us to issue credits or pay service level agreement penalties, cause customers to terminate their on-demand services and adversely affect our renewal rates and our ability to attract new customers.
As part of our business strategy, we acquire other businesses and technologies, and our ability to realize the anticipated benefits of our acquisitions will depend on successfully integrating the acquired businesses.
As part of our business strategy, we have in the past acquired, and expect to continue to acquire, other businesses and technologies. Our prior acquisitions required, and our recently completed acquisitions continue to require, substantial

integration and management efforts, and we expect future acquisitions to require similar efforts. Successfully realizing the benefits of acquisitions involves a number of risks, including:
difficulty in transitioning and integrating the operations and personnel of the acquired businesses;
potential disruption of our ongoing business and distraction of management;
difficulty in incorporating acquired products and technologies into our products and technologies;
potential difficulties in completing projects associated with in-process research and development;
unanticipated expenses and delays in completing acquired development projects and technology integration and upgrades;
challenges associated with managing additional, geographically remote businesses;
impairment of relationships with partners and customers;
assumption of unknown material liabilities of acquired companies;

accurate projection of revenue and bookings plans of the acquired entity in the due diligence process;
customers delaying purchases of our products pending resolution of product integration between our existing and our newly acquired products;
entering markets or types of businesses in which we have limited experience; and
potential loss of key employees of the acquired business.
As a result of these and other risks, if we are unable to successfully integrate acquired businesses, we may not realize the anticipated benefits from our acquisitions. Any failure to achieve these benefits or failure to successfully integrate acquired businesses and technologies could seriously harm our business.
Charges to earnings as a result of our acquisitions may adversely affect our operating results in the foreseeable future, which could have a material and adverse effect on the market value of our common stock.
Under accounting principles generally accepted in the United States, of America, we record the market value of our common stock and other forms of consideration issued in connection with an acquisition as the cost of acquiring the company or business. We allocate that cost to the individual assets acquired and liabilities assumed, including various identifiable intangible assets such as acquired technology, acquired trade names and acquired customer relationships, based on their respective fair values. Our estimates of fair value are based upon assumptions believed to be reasonable but which are inherently uncertain. After we complete an acquisition, the following factors could result in material charges and may adversely affect our operating results and cash flows:
costs incurred to combine the operations of businesses we acquire, such as transitional employee expenses and employee retention, redeployment or relocation expenses;
impairment of goodwill or intangible assets;
amortization of intangible assets acquired;
a reduction in the useful lives of intangible assets acquired;
identification of or changes to assumed contingent liabilities, both income tax and non-income tax related, after our final determination of the amounts for these contingencies or the conclusion of the measurement period (generally up to one year from the acquisition date), whichever comes first;
charges to our operating results to eliminate certain duplicative pre-merger activities, to restructure our operations or to reduce our cost structure;
charges to our operating results resultingarising from expenses incurred to effect the acquisition; and
charges to our operating results due to the expensing of certain stock awards assumed in an acquisition.acquisitions.

Intangible assets are generally amortized over three to ten years. Goodwill is not subject to amortization but is subject to an impairment analysis, at least annually, which may result in an impairment charge if the carrying value exceeds its implied fair value. As of March 31, 2017,2018, we had identified intangible assets of approximately $0.7 billion,$596.1 million, net of accumulated amortization, and goodwill of approximately $3.5 billion.billion, net of accumulated impairment charges. In addition, purchase accounting limits our ability to recognize certain revenue that otherwise would have been recognized by the acquired company as an independent business. As a result, the combined company may delay revenue recognition or recognize less revenue than we and the acquired company would have recognized as independent companies.

We have grown, and may continue to grow, through acquisitions, which could dilute our existing stockholders and/or increase our debt levels.
In connection with past acquisitions, we have in the past issued a substantial number of shares of our common stock as transaction consideration, including contingent consideration, and also incurred significant debt to finance the cash consideration used for our acquisitions. We may continue to issue equity securities for future acquisitions, which would dilute existing stockholders, perhaps significantly, depending on the terms of such acquisitions. We may also incur additional debt in connection with future acquisitions, which, if available at all, may place additional restrictions on our ability to operate our business.
Our strategy to increase cloud services, term licensing and transaction-based recurring revenue may adversely affect our near-term revenue growth and results of operations.
Our ongoing shift from a perpetual software license model to cloud services, term licensing and transaction-based recurring revenue models will create a recurring revenue stream that is more predictable. The transition, however, creates risks related to the timing of revenue recognition. We also incur certain expenses associated with the infrastructures and selling efforts of our hosting offerings in advance of our ability to recognize the revenues associated with these offerings, which may adversely affect our near-term reported revenues, results of operations and cash flows. A decline in renewals of recurring revenue offerings in any period may

not be immediately reflected in our results for that period but may result in a decline in our revenue and results of operations in future quarters.
We have a history of operating losses, and may incur losses in the future, which may require us to raise additional capital on unfavorable terms.
We reported net losses of $151.0 million, $12.5 million $115.0 million and $150.3$115.0 million in fiscal years 2017, 2016 2015 and 2014,2015, respectively, and havea net loss of $164.1 million for the second fiscal quarter of fiscal year 2018. We had a total accumulated deficit of $486.8$691.7 million as of March 31, 2017.2018. If we are unable to return to profitability, the market price for our stock may decline, perhaps substantially. We cannot assure you that our revenue or bookings will grow or that we will return to profitability in the future. If we do not achieve profitability, we may be required to raise additional capital to maintain or grow our operations. Additional capital, if available at all, may be highly dilutive to existing investors or contain other unfavorable terms, such as a high interest rate and restrictive covenants.

If our efforts to execute our formal transformation program are not successful, our business could be harmed.
We have been executing a formal transformation program to focus our product investments on our growth opportunities, increase our operating efficiencies, reduce costs, and further enhance shareholder value through share buybacks. There can be no assurance that we will be successful in executing this transformation program or be able to fully realize the anticipated benefits of this program, within the expected timeframes,time frames, or at all. Additionally, if we are not successful in strategically aligning our product portfolio, we may not be able to achieve the anticipated benefits of this program. A failure to successfully reduce and re-align our costs could have an adverse effect on our revenue and on our expenses and profitability. As a result, our financial results may not meet our or the expectations of securities analysts or investors in the future and our business could be harmed.
Tax matters may cause significant variability in our financial results.
Our businesses are subject to income taxation in the United States, as well as in many tax jurisdictions throughout the world. Tax rates in these jurisdictions may be subject to significant change. If our effective tax rate increases, our operating results and cash flow could be adversely affected. Our effective income tax rate can vary significantly between periods due to a number of complex factors including:
projected levels of taxable income;
pre-tax income being lower than anticipated in countries with lower statutory rates or higher than anticipated in countries with higher statutory rates;
increases or decreases to valuation allowances recorded against deferred tax assets;
tax audits conducted and settled by various tax authorities;
adjustments to income taxes upon finalization of income tax returns;
the ability to claim foreign tax credits;
the repatriation of non-U.S. earnings for which we have not previously provided for income taxes; and
changes in tax laws and their interpretations in countries in which we are subject to taxation.

During 2014, Ireland enacted changes to the taxation of certain Irish incorporated companies effective as of January 2021. On October 5, 2015, the Organization for Economic Cooperation and Development released the Final Reports for its Action Plan on Base Erosion and Profit Shifting. The implementation of one or more of these reports in jurisdictions in which we operate, together with the 2014 enactment by Ireland, could result in an increase to our effective tax rate. In addition, in December 2017, the United States enacted the Tax Cut and Jobs Act of 2017. We expect this to have a material impact on our GAAP tax financial results.  We have determined that our GAAP tax provision for the first quarter of fiscal 2018 was benefited by approximately $80 million driven by a revaluation of certain deferred tax assets and liabilities using the updated federal tax rates, offset in part by a one-time repatriation tax on non-US cash and earnings. Future changes in U.S. and non-U.S. tax laws and regulations could have a material effect on our results of operations in the periods in which such laws and regulations become effective as well as in future periods.
The failure to successfully maintain the adequacy of our system of internal control over financial reporting could have a material adverse impact on our ability to report our financial results in an accurate and timely manner.
Under the Sarbanes-Oxley Act of 2002, we were required to develop and are required to maintain an effective system of disclosure controls and internal control over financial reporting to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements. In addition, our management is required to assess and certify the adequacy of our controls on a quarterly basis, and our independent auditors must attest and report on the effectiveness of our internal control over financial reporting on an annual basis. Any failure in the effectiveness of our system of internal control over financial reporting

could have a material adverse impact on our ability to report our financial statements in an accurate and timely manner. Inaccurate and/or untimely financial statements could subject us to regulatory actions, civil or criminal penalties, shareholder litigation, or loss of customer confidence, which could result in an adverse reaction in the financial marketplace and ultimately could negatively impact our stock price due to a loss of investor confidence in the reliability of our financial statements.
Impairment of our intangible assets could result in significant charges that would adversely impact our future operating results.
We have significant intangible assets, including goodwill and intangibles with indefinite lives,other intangible assets, which are susceptible to valuation adjustments as a result of changes in various factors or conditions. The most significant intangible assets are customer relationships, patents and core technology, completed technology and trademarks. Customer relationships are amortized on an accelerated basis based upon the pattern in which the economic benefits of customer relationships are being utilized. Other identifiable intangible assets are amortized on a straight-line basis over their estimated useful lives. We assess the potential impairment of intangible assets on an annual basis, as well as whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Factors that could trigger an impairment of such assets include the following:
significant underperformance relative to historical or projected future operating results;
significant changes in the manner of or use of the acquired assets or the strategy for our overall business;
significant negative industry or economic trends;
significant decline in our stock price for a sustained period;
changes in our organization or management reporting structure that could result in additional reporting units, which may require alternative methods of estimating fair values or greater disaggregation or aggregation in our analysis by reporting unit; and
our market capitalization declining to below net book value.

For example, during the second quarter of fiscal year 2018, we reorganized our Mobile business into three discrete lines of business. In connection with this reorganization, and with the review of goodwill and indefinite-lived intangible assets for impairment during the second quarter of fiscal year 2018 that was triggered by recent financial results and rapidly changing business conditions for our Subscriber Revenue Services (“SRS”), we recorded a total of $137.9 million of goodwill impairment charge related to our Devices business and SRS for the second quarter of fiscal 2018. For more information, please see Note 4 of the accompanying condensed consolidated financial statements. Future adverse changes in these or other unforeseeable factors could result in an impairment charge that would impact our results of operations and financial position in the reporting period identified.
Our sales to government clients subject us to risks, including early termination, audits, investigations, sanctions and penalties.
We derive a portion of our revenues and bookings from contracts with the United States government, as well as various state and local governments, and their respective agencies. Government contracts are generally subject to oversight, including audits and investigations which could identify violations of these agreements. Government contract violations could result in a range of consequences including, but not limited to, contract price adjustments, civil and criminal penalties, contract termination, forfeiture of profit and/or suspension of payment, and suspension or debarment from future government contracts. We could also suffer serious harm to our reputation if we were found to have violated the terms of our government contracts.
Risks Related to Our Intellectual Property and Technology


Third parties have claimed and may claim in the future that we are infringing their intellectual property, and we could be exposed to significant litigation or licensing expenses or be prevented from selling our products if such claims are successful.
From time to time, we are subject to claims and law actions alleging that we or our customers may be infringing or contributing to the infringement of the intellectual property rights of others. We may be unaware of intellectual property rights of others that may cover some of our technologies and products. If it appears necessary or desirable, we may seek licenses for these intellectual property rights. However, we may not be able to obtain licenses from some or all claimants, the terms of any offered licenses may not be acceptable to us, and we may not be able to resolve disputes without litigation. Any litigation regarding intellectual property could be costly and time-consuming and could divert the attention of our management and key personnel from our business operations. Intellectual property disputes could subject us to significant liabilities, require us to enter into royalty and licensing arrangements on unfavorable terms, prevent us from manufacturing or licensing certain of our products, cause severe disruptions to our operations or the markets in which we compete, or require us to satisfy indemnification commitments with our customers including contractual provisions under various arrangements. Any of these could seriously harm our business.

Unauthorized use of our proprietary technology and intellectual property could adversely affect our business and results of operations.
Our success and competitive position depend in large part on our ability to obtain and maintain intellectual property rights protecting our products and services. We rely on a combination of patents, copyrights, trademarks, service marks, trade secrets, confidentiality provisions and licensing arrangements to establish and protect our intellectual property and proprietary rights. Unauthorized parties may attempt to copy or discover aspects of our products or to obtain, license, sell or otherwise use information that we regard as proprietary. Policing unauthorized use of our products is difficult and we may not be able to protect our technology from unauthorized use. Additionally, our competitors may independently develop technologies that are substantially the same or superior to our technologies and that do not infringe our rights. In these cases, we would be unable to prevent our competitors from selling or licensing these similar or superior technologies. In addition, the laws of some foreign countries do not protect our proprietary rights to the same extent as the laws of the United States. Although the source code for our proprietary software is protected both as a trade secret and as a copyrighted work, litigation may be necessary to enforce our intellectual property rights, to protect our trade secrets, to determine the validity and scope of the proprietary rights of others, or to defend against claims of infringement or invalidity. Litigation, regardless of the outcome, can be very expensive and can divert management efforts.
Our software products may have bugs, which could result in delayed or lost revenue and bookings, expensive correction, liability to our customers and claims against us.
Complex software products such as ours may contain errors, defects or bugs. Defects in the solutions or products that we develop and sell to our customers could require expensive corrections and result in delayed or lost revenue and bookings, adverse customer reaction and negative publicity about us or our products and services. Customers who are not satisfied with any of our products may also bring claims against us for damages, which, even if unsuccessful, would likely be time-consuming to defend, and could result in costly litigation and payment of damages. Such claims could harm our reputation, financial results and competitive position.
Risks Related to our Corporate Structure, Organization and Common Stock
Our debt agreements contain covenant restrictions that may limit our ability to operate our business.
Our debt agreements contain, and any of our other future debt agreements or arrangements may contain, covenant restrictions that limit our ability to operate our business, including restrictions on our ability to:
incur additional debt or issue guarantees;
create liens;
make certain investments;
enter into transactions with our affiliates;
sell certain assets;
repurchase capital stock or make other restricted payments;
declare or pay dividends or make other distributions to stockholders; and
merge or consolidate with any entity.

Our ability to comply with these limitations is dependent on our future performance, which will be subject to many factors, some of which are beyond our control, including prevailing economic conditions. As a result of these limitations, our ability to respond to changes in business and economic conditions and to obtain additional financing, if needed, may be significantly restricted, and we may be prevented from engaging in transactions that might otherwise be beneficial to us. In addition, our failure to comply with our debt covenants could result in a default under our debt agreements, which could permit the holders to accelerate our obligation to repay the debt. If any of our debt is accelerated, we may not have sufficient funds available to repay the accelerated debt.
Our significant debt could adversely affect our financial health and prevent us from fulfilling our obligations under our credit facility and our convertible debentures.

We have a significant amount of debt. AtAs of March 31, 2017,2018, we had a total of $2,918.1$2,587.0 million face valueoutstanding principal amount of debt, outstanding, comprised ofincluding $450.0 million of senior notes due in 2020, $300.0 million of senior notes due in 2024, and $500.0 million of senior notes due in 2026. At March 31, 2017, we also had $1,668.12026, $46.6 million in aggregate principal amount of convertible debentures outstanding comprised of our 2.75% 2031 Convertible Debentures ($377.7 million) redeemable in November 2017, 1.5% 2035 Debentures ($263.9 million) redeemable in November 2021, $263.9 million of 1.5% 2035 Convertible Debentures redeemable in November 2021, $676.5 million of 1.0% 2035 Convertible Debentures ($676.5 million) redeemable in December 2022, and $350.0 million of 1.25% 2025 Convertible Debentures ($350.0 million) redeemable in April 1, 2025. Investors may require us to redeem these debentures earlier than the dates indicated if the closing sale price of our common stock is more than 130% of

the then current conversion price of the respective debentures for certain specified periods. If a holder elects to convert, we will be required to pay the principal amount in cash and any amounts payable in excess of the principal amount in cash or shares of our common stock, at our election. We also havehad a $242.5 million Revolving Credit Facility under which $4.5$4.1 million was committed to backing outstanding letters of credit issued and $238.0$238.4 million was available for borrowing at March 31, 2017.2018. Our debt level could have important consequences, for example it could:
require us to use a large portion of our cash flow to pay principal and interest on debt, including the convertible debentures and the credit facility, which will reduce the availability of our cash flow to fund working capital, capital expenditures, acquisitions, research and development, exploiting business opportunities, and other business activities;
place us at a competitive disadvantage compared to our competitors that have less debt; and
limit, along with the financial and other restrictive covenants related to our debt, our ability to borrow additional funds, dispose of assets or pay cash dividends.
Our ability to meet our payment and other obligations under our debt instruments depends on our ability to generate significant cash flow in the future. This, to some extent, is subject to general economic, financial, competitive, legislative and regulatory factors as well as other factors that are beyond our control. We cannot assure you that our business will generate cash flow from operations, or that additional capital will be available to us, in an amount sufficient to enable us to meet our payment obligations under the convertible debentures and our other debt and to fund other liquidity needs. If we are not able to generate sufficient cash flow to service our debt obligations, we may need to refinance or restructure our debt, including the convertible debentures, sell assets, reduce or delay capital investments, or seek to raise additional capital. If we are unable to implement one or more of these alternatives, we may not be able to meet our payment obligations under the convertible debentures and our other debt.
The market price of our common stock has been and may continue to be subject to wide fluctuations, and this may make it difficult for you to resell the common stock when you want or at prices you find attractive.
Our stock price historically has been, and may continue to be, volatile. Various factors contribute to the volatility of our stock price, including, for example, quarterly variations in our financial results, new product introductions by us or our competitors and general economic and market conditions. Sales of a substantial number of shares of our common stock by our largest stockholders, or the perception that such sales could occur, could also contribute to the volatility or our stock price. While we cannot predict the individual effect that any of these factors may have on the market price of our common stock, these factors, either individually or in the aggregate, could result in significant volatility in our stock price. Moreover, companies that have experienced volatility in the market price of their stock often are subject to securities class action litigation. Any such litigation could result in substantial costs and divert management's attention and resources.
Current uncertainty in the global financial markets and the global economy may negatively affect the value of our investment portfolio.
Our investment portfolio,portfolios, which includesinclude investments in money market funds, bank deposits and a separately managed investment portfolio, isportfolios, are generally subject to credit, liquidity, counterparty, market and interest rate risks that may be exacerbated by a global financial crisis or by uncertainty surrounding the United Kingdom's exit from the European Union. If the banking

system or the fixed income, credit or equity markets deteriorate or remain volatile, our investment portfolio may be impacted and the values and liquidity of our investments could be adversely affected.
Future issuances of our common stock could adversely affect the trading price of our common stock and our ability to raise funds in new stock offerings.
Future issuances of substantial amounts of our common stock, whether in the public market or through private placements, including issuances in connection with acquisition activities, or the perception that such issuances could occur, could adversely affect prevailing trading prices of our common stock and could impair our ability to raise capital through future offerings of equity or equity-related securities. In connection with past acquisitions, we issued a substantial number of shares of our common stock as transaction consideration or contingent consideration. We may continue to issue equity securities for future acquisitions, which would dilute existing stockholders, perhaps significantly depending on the terms of such acquisitions. No prediction can be made as to the effect, if any, that future sales of shares of common stock, or the availability of shares of common stock for future sale, will have on the trading price of our common stock.
Our business could be negatively affected by the actions of activist stockholders.
In recent periods, certain stockholders have publicly and privately expressed concerns with the Company’s performance and with certain governance matters. For example, certain stockholders have expressed concerns about the timing and process related to

our former chief executive officer retiring and the appointment of a new chief executive officer, certain provisions of our executive compensation plans and features of our corporate governance provisions in our governing documents and policies. In addition, we have enacted certain changes to our bylaws in the past year in response to demands from stockholders that may weaken our ability to prevent an unsolicited takeover. Responding to actions by activist stockholders can be costly and time-consuming, disrupting our operations and diverting the attention of management and our employees. Furthermore, any perceived uncertainties as to our future direction could result in the loss of potential business opportunities, and may make it more difficult to attract and retain qualified personnel and business partners.

Item 2.Unregistered Sales of Equity Securities and Use of Proceeds

On February 7, 2017, we issued 844,108 shares of our common stock in connection with a business acquisition. The shares were issued in reliance upon an exemption from the registration requirements of the Securities Act of 1933, as amended, provided by Section 4(a)(2) thereof because the issuance did not involve a public offering.

The following is a summary of our share repurchases for the three months ended March 31, 2017:

(1) On April 29, 2013, our Board of Directors approved a share repurchase program for up to $500.0 million of our outstanding shares of common stock. On April 29, 2015, our Board of Directors approved an additional $500.0 million under our share repurchase program. The plan has no expiration date. As of March 31, 2017, approximately $193.4 million of repurchasing authority remained available.
For the majority of restricted stock units granted to employees, the number of shares issued on the date the restricted stock units vest is net of the minimum statutory income withholding tax requirements that we pay in cash to the applicable taxing authorities on behalf of our employees. We do not consider these transactions to be common stock repurchases.None.
