SolarWinds Corporation
Notes to Condensed Consolidated Financial Statements (Unaudited)



1. Organization and Nature of Operations
SolarWinds Corporation, a Delaware corporation, and its subsidiaries (“Company” or “Successor”, “we,” “us” and “our”) is a leading provider of information technology, or IT, infrastructure management software. References to “we,” “us” and “our” refer to the Company. Our products give organizations worldwide, regardless of type, size or IT infrastructure complexity, the power to monitor and manage the performance of their IT environments, whether on-premise, in the cloud, or in hybrid infrastructure models. Our approach, which we refer to as the SolarWinds Model, combines powerful, scalable, affordable, easy to use products with high-velocity, low-touch sales. We’ve built our business to enable the technology professionals who use our products to manage “all things IT.” Our range of customers has expanded over time from network and systems engineers to a broad set of technology professionals, such as database administrators, storage administrators, web operators and DevOps professionals, as well as managed service providers, or MSPs. Our SolarWinds Model enables us to sell our products for use in organizations ranging in size from very small businesses to large enterprises.
Initial Public Offering
In October 2018, we completed our initial public offering, or IPO, in which we sold and issued 25,000,000 shares of our common stock at an issue price of $15.00 per share. Upon the closing of our IPO, all shares of Class A Common Stock that were outstanding immediately prior to the closing of the offering converted into shares of common stock in accordance with the terms of our certificate of incorporation. In addition, we converted the accrued and unpaid dividends on the Class A Common Stock into shares of common stock equal to the result of the accrued and unpaid dividends on each share of Class A Common Stock, divided by the conversion price of $19.00 per share. See Note 13. Subsequent Eventsfor additional details. The condensed consolidated financial statements as of September 30, 2018, including share and per share amounts, do not give effect to the sale of shares in connection with the IPO or conversion of Class A Common Stock as the IPO was completed subsequent to September 30, 2018.
2. Summary of Significant Accounting Policies
We prepared our interim condensed consolidated financial statements in conformity with United States of America generally accepted accounting principles, or GAAP, and the reporting regulations of the Securities and Exchange Commission, or the SEC. They do not include all of the information and footnotes required by GAAP for complete financial statements. The accompanying condensed consolidated financial statements include the accounts of SolarWinds Corporation and the accounts of its wholly owned subsidiaries. We have eliminated all intercompany balances and transactions.
The interim financial information is unaudited, but reflects all normal adjustments that are, in our opinion, necessary to provide a fair statement of results for the interim periods presented. This interim information should be read in conjunction with the audited consolidated financial statements in our Annual Report on Form 10-K for the year ended December 31, 2017, contained2018.
With the exception of the change in our final prospectus dated October 18, 2018revenue recognition and filed withother related policies upon the SECadoption of new revenue accounting standard described below, there have been no material changes to our significant accounting policies described in our Annual Report on October 22, 2018 pursuant to Rule 424(b)Form 10-K for the year ended December 31, 2018. See Recently Adopted Accounting Pronouncements below regarding the impact of the Securities Actadoption of 1933, as amended.the new revenue accounting standard and Revenue Recognitionfor discussion of our updated revenue recognition policies.
Use of Estimates
The preparation of financial statements in conformity with GAAP requires our management to make estimates and assumptions that affect the reported amounts and the disclosure of assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting periods. The actual results that we experience may differ materially from our estimates. The accounting estimates that require our most significant, difficult and subjective judgments include:
the valuation of goodwill, intangibles, long-lived assets and contingent consideration;
revenue recognition;
stock-based compensation;
income taxes; and
loss contingencies.
Foreign Currency Translation
The functional currency of our foreign subsidiaries is determined in accordance with authoritative guidance issued byRecently Adopted Accounting Pronouncements
On January 1, 2019 we adopted the Financial Accounting Standards Board, or FASB.FASB, Accounting Standards Codification (ASC) No. 2014-09 “Revenue from Contracts with Customers,” or ASC 606, which replaced all existing revenue guidance under ASC 605 “Revenue Recognition,” including prescriptive industry-specific guidance, or ASC 605. This standard’s core principle is that an entity will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. We translate assets and liabilitiesadopted ASC 606 using the modified-retrospective method. Results for these subsidiaries at exchange ratesreporting periods beginning after January 1, 2019 are presented in effect atcompliance with the balance sheet date. We translate income and expense accountsnew revenue recognition standard ASC 606. Historical financial results for these subsidiaries atreporting periods prior to 2019 are presented in conformity with amounts previously disclosed under the average monthly exchange ratesprior revenue recognition standard, ASC 605. These financial statements include additional information regarding the impacts from the adoption of the new revenue recognition standard on our financial results for the periods. We record resulting translation adjustments as a componentthree month period ended March 31, 2019. This includes the presentation of accumulated other comprehensive income (loss) within stockholders’ equity (deficit). We record gains and losses from currency transactions denominated in currencies other thanfinancial results for the functional currency as other income (expense) in our consolidated statements of operations. There were no equity transactionsthree month period ended March 31, 2019 under ASC 605 for comparison to the prior year period.

denominatedThe most significantly impacted areas are the following:

License and Recurring Revenue. The adoption of the new standard resulted in foreign currencieschanges to the classification and timing of our revenue recognition. Under the new guidance, the requirement to establish VSOE to recognize license revenue separately from the other elements is eliminated. This change impacted the allocation of the transaction price and timing of our revenue recognition between deliverables, or performance obligations, within an arrangement. In addition, we now recognize time-based license revenue upon the transfer of the license and the associated maintenance revenue over the contract period under the new standard instead of recognizing both the license and maintenance revenue ratably over the contract period. The overall adoption impact to total revenue is immaterial, though we do expect some changes to the timing and classification between license and recurring revenue. Additionally, some historical deferred revenue, primarily from arrangements involving time-based licenses, will never be recognized as revenue and instead has been recorded as a cumulative effect adjustment within accumulated deficit.

Contract Acquisition Costs. We expensed all sales commissions as incurred under the previous guidance. The new guidance requires the deferral and amortization of certain direct and incremental costs incurred to obtain a contract. This guidance requires us to capitalize and amortize certain sales commission costs over the remaining contractual term or over an expected period of benefit, which we have determined to be approximately six years.

Other Items. The impact of the adoption of the new standard on income taxes resulted in an increase of deferred income tax liabilities. The adoption of this standard did not impact our total operating cash flows.

The impact of exchange for monetary assets and liabilities and historical ratesadoption of exchange for non-monetary assets and liabilities.
We recorded an immaterial net transaction loss related to the remeasurement of monetary assets and liabilities for the three months ended September 30, 2018 and a net transaction gain of $14.3 million for the three months ended September 30, 2017 withinASC 606 on our condensed consolidated statements of operations. We recorded a net transaction loss related to the remeasurement of monetary assets and liabilities of $14.0 million and a net transaction gain of $48.2 million within our consolidated statementsstatement of operations for the nine months ended September 30, 2018 and 2017, respectively.condensed consolidated balance sheet was as follows:
As of July 1, 2018, we changed our assertion regarding the planned settlement of a certain intercompany loan. We have evaluated our investment strategy in light of our global treasury plans and the new Tax Act (as defined below) and have determined there is no need to settle the principal related to the loan. The intercompany loan has been designated as long-term based on the assertion that settlement is not planned or anticipated in the foreseeable future. Therefore, beginning on July 1, 2018, the foreign currency transaction gains and losses resulting from the remeasurement of this long-term intercompany loan denominated in a currency other than the subsidiary's functional currency are recognized as a component of accumulated other comprehensive income (loss). In the three months ended September 30, 2018, a foreign currency translation adjustment of $3.3 million was recognized as a component of accumulated other comprehensive income related to this long-term intercompany loan.

Recent Accounting Pronouncements Not Yet Adopted
Under the Jumpstart our Business Startups Act, or the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards until such time as those standards apply to non-public companies. We intend to take advantage of the longer phase-in periods for the adoption of new or revised financial accounting standards permitted under the JOBS Act until we are no longer an emerging growth company.
In May 2014, FASB issued “Revenue from Contracts with Customers,” which replaced all existing revenue guidance, including prescriptive industry-specific guidance. This standard’s core principle is that an entity will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Entities will need to apply more judgment and make more estimates than under the previous guidance. In July 2015, FASB deferred the effective date for all entities by one year, making the guidance for non-public companies effective for annual reporting periods beginning after December 15, 2018. Early adoption is permitted to the original effective date of December 15, 2016. The standard permits the use of either a full-retrospective or a modified-retrospective transition method. We will adopt the new standard effective first quarter 2019. Management anticipates using the modified-retrospective method for adoption.
In preparation for this planned adoption, we have been evaluating the impact of the new standard to our financial statements and accompanying disclosures in the notes to our consolidated financial statements. Our assessment of the impact includes an evaluation of the five-step process set forth in the new standard along with the enhancement of disclosures that will be required. We are in the process of executing our plan for implementing the standard, which includes identifying customer contracts within the scope of the new standard, identifying performance obligations within those customer contracts, and evaluating the impact of incremental variable consideration paid to obtain those customer contracts. We have also undertaken a comprehensive review of all contracts that fall under the scope of the new standard. We are continuing our review of in-scope contracts and reviewing all potential impacts of the standard, including the tax related impact.

Notes to Condensed Consolidated Financial Statements (Unaudited)


Based on analysis performed to date, we expect that adoption of the new standard will result in changes to the classification and timing of our revenue recognition. The most significantly impacted areas are the following:
License and Recurring Revenue. Under the new guidance, the requirement to establish VSOE to recognize license revenue separately from the other elements is eliminated. This change is expected to impact the allocation of the transaction price and timing of our revenue recognition between deliverables, or performance obligations, within an arrangement. In addition, we will recognize time-based license revenues upon the transfer of the license and the associated maintenance revenue over the contract period under the new standard instead of recognizing both the license and maintenance revenue ratably over the contract period. We expect the overall adoption impact to total revenue to be immaterial, though we do expect some changes to the timing and classification between license and recurring revenues. Additionally, some deferred revenue, primarily from arrangements involving time-based licenses, will never be recognized as revenue and instead will be a cumulative effect adjustment within accumulated deficit. We expect an immaterial reduction to the deferred revenue balance as a cumulative effect adjustment upon adoption.
Contract Acquisition Costs. We expense all sales commissions as incurred under current guidance. The new guidance requires the deferral and amortization of certain incremental costs incurred to obtain a contract. This guidance will require us to capitalize and amortize certain sales commission costs over the remaining contractual term or over an expected period of benefit, which we have determined to be approximately three to six years. As part of the transition to the new guidance, we will recognize a contract asset as a cumulative effect adjustment upon adoption.
We do not expect the changes described above to have a material impact on our quarterly or annual consolidated financial statements, however the exact impact of the new standard will be dependent on facts and circumstances that could vary from quarter to quarter.
In February 2016, FASB issued an accounting standard to provide updated guidance requiring the recognition of all lease assets and liabilities on the balance sheet. The accounting standard required the use of a modified retrospective transition method. In July 2018, FASB issued additional guidance that provides entities with an optional transition method in which an entity can apply the new standard at the adoption date and recognize a cumulative-effect adjustment to the opening balance retained earnings in the period of adoption. The updated accounting guidance is effective for non-public companies for fiscal years beginning after
SolarWinds Corporation
Notes to Condensed Consolidated Financial Statements (Unaudited)


December 15, 2019 and interim periods beginning the following year. Early adoption is permitted and the standard provides for certain practical expedients. We expect to adopt the updated guidance in fiscal year 2020. Our evaluation of the new standard will extend into future periods and we will update our disclosures, including the expected impacts of the new standard, as we progress towards the required adoption date.
In January 2017, FASB issued an accounting standard to simplify the accounting for goodwill impairment. The new guidance removes step two of the two-step quantitative goodwill impairment test, which requires a hypothetical purchase price allocation. The updated guidance is effective for non-public companies for fiscal years beginning after December 15, 2021 and may be adopted early for any interim or annual goodwill impairment tests performed after January 1, 2017. We expect to adopt the updated guidance in fiscal year 2022. We do not believe that this standard will have a material impact on our consolidated financial statements.
Fair Value Measurements
We apply the authoritative guidance on fair value measurements for financial assets and liabilities that are measured at fair value on a recurring basis and non-financial assets and liabilities, such as goodwill, intangible assets and property, plant and equipment that are measured at fair value on a non-recurring basis.
The guidance establishes a three-tiered fair value hierarchy that prioritizes inputs to valuation techniques used in fair value calculations. The three levels of inputs are defined as follows:
Level 1: Unadjusted quoted prices for identical assets or liabilities in active markets accessible by us.
Level 2: Inputs that are observable in the marketplace other than those inputs classified as Level 1.
Level 3: Inputs that are unobservable in the marketplace and significant to the valuation.
See Note 5.3. Fair Value Measurements for a summary of our financial instruments accounted for at fair value on a recurring basis. The carrying amounts reported in our consolidated balance sheets for cash, accounts receivable, accounts payable and other accrued expenses approximate fair value due to relatively short periods to maturity.

Deferred Offering Costs
Deferred offering costs, primarily consisting of legal, accounting, printer, and other direct fees and costs, related to our proposed initial public offering are capitalized. The deferred offering costs were offset against proceeds from our initial public offering upon the closing of the offering in October 2018. As of September 30, 2018, we have capitalized $2.2 million of offering costs in the consolidated balance sheet. As of December 31, 2017, we had not yet capitalized any offering costs in the consolidated balance sheet.

Revenue Recognition
We generate recurring revenue from fees received for subscriptions and from the sale of maintenance services associated with our perpetual license products and license revenue from the sale of our perpetual license products. We recognize revenue related to contracts from customers when we transfer promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This is determined by following a five-step process which includes (1) identifying the contract with a customer, (2) identifying the performance obligations in the contract, (3) determining the transaction price, (4) allocating the transaction price, and (5) recognizing revenue when or as we satisfy a performance obligation, as described below.
Identify the contract with a customer. We generally use a purchase order, an authorized credit card, an electronic or manually signed license agreement, or the receipt of a cash payment as evidence of a contract with a customer provided that collection is considered probable. We sell our products through our direct sales force and through our distributors and resellers. Our distributors and resellers do not carry inventory of our software and we generally require them to specify the end user of the software at the time of the order. If the distributor or reseller does not provide end-user information, then we will generally not fulfill the order. Our distributors and resellers have no rights of return or exchange for software
SolarWinds Corporation
Notes to Condensed Consolidated Financial Statements (Unaudited)


that they purchase from us and payment for these purchases is due to us without regard to whether the distributors or resellers collect payment from their customers. Sales through resellers and distributors are typically evidenced by a reseller or distributor agreement, together with purchase orders or authorized credit cards on a transaction-by-transaction basis.
Identify the performance obligations in the contract. Performance obligations promised in a contract are identified based on the goods or services that will be transferred to the customer that are separately identifiable from other promises in the contract, or distinct. If not considered distinct, the promised goods or services are combined with other goods or services and accounted for as a combined performance obligation. Determining the distinct performance obligations in a contract requires judgment. Our performance obligations primarily include perpetual and time-based licenses, maintenance support including unspecified upgrades or enhancements to new versions of their software products and subscriptions to our software-as-a-service, or SaaS, offerings. See additional discussion of our performance obligations below.
Determine the transaction price. We determine the transaction price based on the contractual consideration and the amount of consideration we expect to receive in exchange for transferring the promised goods or services to the customer. We account for sales incentives to customers, resellers or distributors as a reduction of revenue at the time we recognize the revenue from the related product sale. We report revenue net of any sales tax collected. Our return policy generally does not allow our customers to return software products.
Allocate the transaction price. We allocate the transaction price of the contract to each distinct performance obligation based on a relative standalone selling price basis. Determining standalone selling prices for our performance obligations requires judgment and are based on multiple factors including, but not limited to historical selling prices and discounting practices for products and services, internal pricing policies and pricing practices in different regions and through different sales channels. For our subscription products and maintenance services, our standalone selling prices are generally observable using standalone sales or renewals. For our perpetual and time-based license products, we estimate our standalone selling prices utilizing the residual approach by considering our pricing and discounting practices. We review the standalone selling price for our performance obligations periodically and update, if needed, to ensure that the methodology utilized reflects our current pricing practices.
Recognize revenue when or as we satisfy a performance obligation. Revenue is recognized when or as performance obligations are satisfied either over time or at a point in time by transferring a promised good or service. We consider this transfer to have occurred when risk of loss transfers to the customer, reseller or distributor or the customer has access to their subscription which is generally upon electronic transfer of the license key or password that provides immediate availability of the product to the purchaser. See further discussion below regarding the timing of revenue recognition for each of our performance obligations.
The following summarizes our performance obligations from which we generate revenue:
Performance obligationWhen performance obligation is typically satisfied
Subscription revenue
SaaS offeringsOver the subscription term, once the service is made available to the customer (over time)
Time-based licensesUpon the delivery of the license key or password that provides immediate availability of the product (point in time)
Time-based technical support and unspecified software upgradesRatably over the contract period (over time)
Maintenance revenue
Technical support and unspecified software upgradesRatably over the contract period (over time)
License revenue
Perpetual licensesUpon the delivery of the license key or password that provides immediate availability of the product (point in time)
Recurring Revenue. Recurring revenue consists of subscription and maintenance revenue.
Subscription Revenue. We primarily derive subscription revenue from fees received for subscriptions to our SaaS offerings and our time-based license arrangements. We generally invoice subscription agreements monthly based on usage or monthly in advance over the subscription period. Subscription revenue for our SaaS offerings is generally recognized ratably over the subscription term once the service is made available to the customer or when we have the right to invoice
SolarWinds Corporation
Notes to Condensed Consolidated Financial Statements (Unaudited)


for services performed. Revenue for the license performance obligation of our time-based license arrangements is recognized at a point in time upon delivery of the license key and the revenue for the technical support performance obligation of our time-based license arrangements is recognized ratably over the contract period. The amount of revenue related to the license performance obligations of our time-based license arrangements included in subscription revenue is less than 10% of our total consolidated revenue. Our subscription revenue includes our cloud management and MSP products.
Maintenance Revenue. We derive maintenance revenue from the sale of maintenance services associated with our perpetual license products. We typically include one year of maintenance service as part of the initial purchase price of each perpetual software offering and then sell renewals of this maintenance agreement. Customers with maintenance agreements are entitled to receive technical support and unspecified upgrades or enhancements to new versions of their software products on a when-and-if-available basis for the specified contract period. We believe that our technical support and unspecified upgrades or enhancements performance obligations each have the same pattern of transfer to the customer and are therefore accounted for as a single distinct performance obligation. We recognize maintenance revenue ratably on a daily basis over the contract period.
License Revenue. We derive license revenue from the sale of our perpetual licenses. Revenue for the license performance obligation of our perpetual license arrangements is recognized at a point in time upon delivery of the electronic license key. Perpetual license arrangements are invoiced upon delivery.
Deferred Revenue
Deferred revenue primarily consists of transaction prices allocated to remaining performance obligations from maintenance services associated with our perpetual license products which are delivered over time. We generally bill maintenance agreements annually in advance for services to be performed over a 12-month period. Customers have the option to purchase maintenance renewals for periods other than 12 months. We initially record the amounts allocated to maintenance performance obligations as deferred revenue and recognize these amounts ratably on a daily basis over the term of the maintenance agreement. We record deferred revenue that will be recognized during the succeeding 12-month period as current deferred revenue and the remaining portion is recorded as long-term deferred revenue.

Contract Acquisition Costs
Our contract acquisition costs, which consist of direct and incremental sales commissions and related fringe benefits, are capitalized using the portfolio approach if we expect to benefit from those costs for more than one year. Contract acquisition costs are allocated to each performance obligation within the contract and amortized on a straight-line basis over the expected benefit period of the related performance obligations. Contract acquisition costs allocated to new maintenance arrangements and SaaS offerings are generally amortized over an average expected benefit period of approximately six years which was determined based on the expected life of our technology. Contract acquisition costs allocated to perpetual licenses and maintenance renewal

arrangements are expensed or amortized over a period that is consistent with the timing of delivery for the related products and services. We expense contract acquisition costs as incurred when the expected amortization period is one year or less. Deferred contract acquisition costs are classified as current or non-current assets based on the timing the expense will be recognized. The current and non-current portions of our deferred contract acquisition costs are included in prepaid and other current assets and other assets, net respectively, in our condensed consolidated balance sheets. The amortization of our deferred contract acquisition costs is included in sales and marketing expense in our condensed consolidated statement of operations.

3. Acquisitions
In the nine months ended September 30, 2018, we completed acquisitions for a combined purchase price of approximately $62.9 million in cash, including $2.4 million of cash acquired. The acquisitions were funded with available cash on hand. We incurred $0.9 million in acquisition related costs, which are included in general and administrative expense for the nine months ended September 30, 2018. Goodwill for these acquisitions is not deductible for tax purposes.
The initial determination of the fair value of the assets acquired and liabilities assumed is based on a preliminary valuation and the estimates and assumptions for these items are subject to change as we obtain additional information during the measurement period. Subsequent changes to the purchase price or other fair value adjustments determined during the measurement period will be recorded as an adjustment to goodwill.
The amounts of revenue and net loss related to these acquisitions included in our condensed consolidated financial statements from the effective date of the respective acquisitions are insignificant for the nine months ended September 30, 2018. Pro forma information for these acquisitions have not been provided because the impact of the historical financials on our revenue, net loss and loss per share is not material.

Senior Secured First Lien Credit Facilities
On February 5, 2016, we were acquired by the Sponsors in a take private transaction, or the Take Private. In connection with the Take Private, we entered into a first lien credit agreement with Credit Suisse AG, Cayman Islands Branch, or Credit Suisse, as administrative agent and collateral agent, and a syndicate of institutional lenders and financial institutions, or Initial First Lien Credit Agreement.
In March 2018, we entered into Amendment No. 4 to the Initial First Lien Credit Agreement, or Amendment No. 4, which replaced the outstanding borrowings with a new $1.99 billion U.S. dollar term loan, or First Lien Term Loan. The Initial First Lien Credit Agreement, as amended, is referred to here as the First Lien Credit Agreement. The proceeds of the First Lien Term Loan were used to repay all outstanding borrowings including accrued interest under the existing First Lien Term Loan and a portion of the Second Lien Notes, including accrued interest and related transaction costs. In connection with Amendment No. 4, a loss on debt extinguishment of $21.4 million was recorded to other income (expense) in the consolidated statement of operations for the nine months ended September 30, 2018.
The First Lien Credit Agreement provides for senior secured first lien credit facilities, consisting as of September 30, 2018March 31, 2019 of:
a $1.99 billion First Lien Term Loan with a final maturity date of February 5, 2024; and
a $125.0 million revolving credit facility (with a letter of credit sub-facility in the amount of $35.0 million), or the Revolving Credit Facility, consisting of (i) a $100.0 million multicurrency tranche and (ii) a $25.0 million tranche available only in U.S. dollars, of which $7.5 million has a final maturity date of February 5, 2021 and $17.5 million has a final maturity date of February 5, 2022.

The Eurodollar rate is equal to an adjusted London Interbank Offered Rate, or LIBOR, for a one-, two-, three- or six-month interest period with a LIBOR floor of 0%. The base rate for any day is a fluctuating rate per annum equal to the highest of (a) the rate of interest in effect for such day as publicly announced by Credit Suisse as its “prime rate” and (b) the federal funds effective rate in effect on such day plus 0.50% and (c) the one-month adjusted LIBOR plus 1.0% per annum.
The First Lien Term Loan requires equal quarterly repayments equal to 0.25% of the original principal amount.
In addition to paying interest on loans outstanding under the Revolving Credit Facility and the First Lien Term Loan, we are required to pay a commitment fee of 0.50% per annum of unused commitments under the Revolving Credit Facility. The commitment fee is subject to a reduction to 0.375% per annum based on our first lien net leverage ratio.
The First Lien Credit Agreement contains a number of covenants that, among other things, restrict, subject to certain exceptions, our ability to: incur additional indebtedness; incur liens; engage in mergers, consolidations, liquidations or dissolutions; pay dividends and distributions on, or redeem, repurchase or retire our capital stock; and make certain investments, acquisitions, loans, or advances. In addition, the terms of the First Lien Credit Agreement include a financial covenant which requires that, at the end of each fiscal quarter, if the aggregate amount of borrowings under the Revolving Credit Facility exceeds 35% of the aggregate commitments under the Revolving Credit Facility, our first lien net leverage ratio cannot exceed 7.40 to 1.00. The First Lien Credit Agreement also contains certain customary representations and warranties, affirmative covenants and events of default. As of September 30, 2018,March 31, 2019, we were in compliance with all covenants of the First Lien Credit Agreement.

Senior Secured Second Lien Credit Facility
In March 2018, we terminated the agreements governing our senior secured second lien floating rate notes, or the Second Lien Notes, and repaid or exchanged the then-outstanding principal on our Second Lien Notes of $680.0 million and replaced the Second Lien Notes with a new second lien credit agreement, or the Second Lien Credit Agreement, with Wilmington Trust, National Association or Wilmington Trust, as administrative agent and collateral agent, and certain other financial institutions. The Second Lien Credit Agreement provides for a $315.0 million U.S. dollar term loan, or the Second Lien Term Loan, with a final maturity of February 5, 2025 and does not require periodic principal payments. In connection with the redemption and exchange of our Second Lien Notes, a loss on debt extinguishment of $39.2 million, which includes a $22.7 million redemption premium, was recorded to other income (expense) in the consolidated statement of operations for the nine months ended September 30, 2018.
The borrowings under the Second Lien Term Loan bear interest at a floating rate which can be, at our option, either (1) a Eurodollar rate for a specified interest period plus an applicable margin of 7.25% or (2) a base rate plus an applicable margin of 6.25%. The Eurodollar rate is equal to the adjusted LIBOR Rate for a one-, two-, three or six-month interest period. The base rate for any day is a fluctuating rate per annum equal to the rate last quoted by the Wall Street Journal as the “Prime Rate” in the United States, or if the Wall Street Journal ceases to quote such rate, the highest per annum interest rate published by the Federal Reserve Board as “bank prime loan” rate or, if such rate is no longer quoted therein (as determined by Wilmington Trust) or any similar release by the Federal Reserve Board (as determined by Wilmington Trust).

In October 2018, we completed our IPO and used a portion of the net proceeds from the offering to repay the $315.0 million in borrowings outstanding under our Second Lien Term Loan. See Note 13. Subsequent Eventsfor additional information.
7.5. Redeemable Convertible Class A Common Stock
Prior to the conversion of Class A Common Stock into common stock at our IPO in October 2018, our Class A Common Stock accrued dividends at a rate of 9% per annum and had a liquidation preference equal to $1,000 per share plus any accrued and unpaid dividends. Prior to the conversion of the Class A Common Stock into common stock, in a future liquidation event, such as a sale, the holders of the Class A Common Stock would have been entitled to payment up to the amount of the liquidation preference and holders of the Class B Common Stock would have been entitled to the residual value of the Company.
Cumulative undeclared and unpaid dividends on Class A Common Stock totaled $702.5 million and $485.9 million at September 30, 2018 and December 31, 2017, respectively. Redeemable convertible Class A Common Stock was recorded at liquidation value plus accrued, unpaid dividends in our consolidated balance sheets.
Immediately prior to the completion of our IPO, in October 2018, we converted each outstanding share of our Class A Common Stock into a number of140,053,370 shares of common stock, which was equal to the result of the liquidation value of such share of Class A Common Stock, divided by $19.00 per share. The liquidation value for each share of Class A Common Stock was equal to $1,000. At the time of the conversion of the Class A Common Stock, we converted $717.4 million of accrued and unpaid dividends on the Class A Common Stock into 37,758,109 shares of common stock equal to the result of the accrued and unpaid dividends on each share of Class A Common Stock, divided by $19.00 per share. See Note 13. Subsequent Eventsfor additional information regarding the conversion of our Class A Common Stock.
8. Stockholders’ Deficit and Stock-Based Compensation
Common Stock
As of September 30, 2018, the Company had authorized capital stock of 238,755,000 shares consisting of 5,755,000 shares of Class A Common Stock, par value $0.001 per share, or Class A Common Stock, and 233,000,000 shares of Class B Common Stock, par value of $0.001 per share, or Class B Common Stock. See Note 13. Subsequent Eventsfor additional information regarding the conversion of our Class A Common Stock and Class B Common Stock into common stock immediately prior to the completion of our IPO.
2016 Equity Plan
Equity awards to the Company’s employees, consultants, directors, managers and advisors are issued by the Company. The board of directors adopted, and the stockholders approved, the SolarWinds Corporation Equity Plan, or 2016 Plan, in June 2016. Under the 2016 Plan, the Company is able to sell or grant shares of Class A Common Stock and Class B Common Stock and common stock-based awards, including nonqualified stock options, to the Company’s employees, consultants, directors, managers and advisors.
The Company has issued common stock-based incentive awards, consisting of nonqualified stock options exercisable for shares of Class B Common Stock and restricted shares of Class B Common Stock, under the 2016 Plan to employees and certain members of the Company’s board of directors. As of September 30, 2018, common stock-based incentive awards of 8,241,934 were outstanding under the 2016 Plan consisting of 3,199,400 stock options and 5,042,534 shares of restricted Class B Common Stock and 502,833 shares of Class B Common Stock were reserved for future equity incentive awards under the 2016 Plan. For the nine months ended September 30, 2018, the Company repurchased 250,333 shares of vested and unvested restricted Class B Common Stock upon employee terminations.

Stock-based compensation expense related to stock option awards recorded for the three and nine months ended September 30, 2018 and 2017 was immaterial. The unrecognized stock-based compensation expense related to unvested stock options and subject to recognition in future periods was approximately $2.5 million and $0.3 million as of September 30, 2018 and December 31, 2017, respectively. We expect to recognize this expense over weighted average periods of approximately 3.5 years and 3.8 years at September 30, 2018 and December 31, 2017, respectively.

Unvested balances at September 30, 20185,042,534
Restricted stock is purchased at fair market value by the employee and Class B Common Stock is issued at the date of grant. The weighted-average grant date fair market value of restricted Class B Common Stock purchased was $2.10 per share for the nine months ended September 30, 2018. Restricted stock is subject to certain restrictions, such as vesting and a repurchase right. The Class B Common Stock acquired by the employee is restricted stock because vesting is conditioned upon (i) continued employment through the applicable vesting date and (ii) for employees at the level of group vice president and above, the achievement of certain financial performance targets determined by the board of directors. The restricted stock is subject to repurchase in the event the stockholder ceases to be employed or engaged (as applicable) by the Company for any reason or in the event of a change of control or due to certain regulatory burdens. As the restricted stock is purchased at fair market value at the time of grant, there is no stock-based compensation expense recognized related to these awards. The related liability for unvested

11.7. Income Taxes
For the three months ended September 30,March 31, 2019 and 2018, and 2017, we recorded income tax expense of $0.6 million and income tax benefit of $0.1 million and $3.1$8.4 million, respectively, resulting in an effective tax rate of 24.0%15.2% and 215.4%, respectively. For the nine months ended September 30, 2018 and 2017, we recorded income tax benefit of $20.0 million and $12.5 million, respectively, resulting in an effective tax rate of 18.7% and 22.0%12.2%, respectively. The decreaseincrease in the effective tax rate for the three and nine months ended September 30, 2018March 31, 2019 compared to the same periodsperiod in 2017 were2018 was generally a result of the lower U.S. corporate tax rate attributable to the Tax Cuts and Jobs Act, or the Tax Act, as well as discrete items related to expired statutes in various jurisdictions.
The Tax Act reduces the U.S. federal corporate tax rate from 35% to 21%, requires companies to pay a one-time transition tax on earnings of certain foreign subsidiaries that have not been taxed previouslydecrease in the U.S., and creates new taxes on certain foreign sourced earnings. We are required to recognize the effect of the tax law changes in the period of enactment, such as determining the transitionbenefit partially offset by excess tax re-measuring our U.S. deferred tax assets and liabilities as well as reassessing the net realizability of our deferred tax assets and liabilities. In December 2017, the SEC staff issued Staff Accounting Bulletin No. 118, Income Tax Accounting Implications of the Tax Cuts and Jobs Act (SAB 118), which allows us to record provisional amounts during a measurement period not to extend beyond one year of the enactment date. Due to the timing of the enactment and the complexity involved in applying the provisions of the Tax Act, the Company made reasonable estimates of the effects and recorded provisional amounts in our consolidated financial statements for the year ended December 31, 2017.
As the Company collects and prepares the necessary data, interprets the Tax Act and reviews any additional guidance issued by the U.S. Treasury Department, state taxation authorities and other standard-setting bodies, the Company may make adjustments to the provisional amounts noted above which may materially impact its provision for income taxesbenefit from continuing operations in the period in which the adjustments are made. The accounting for the tax effects of the Tax Act will be completed in 2018.stock-based compensation.
Our policy is to include interest and penalties related to unrecognized tax benefits as a component of income tax expense. At September 30, 2018,March 31, 2019, we had accrued interest and penalties related to unrecognized tax benefits of approximately $3.8$4.3 million.
We file U.S., state and foreign income tax returns in jurisdictions with varying statutes of limitations. The 2011 through 2017 tax years generally remain open and subject to examination by federal tax authorities. The 20102011 through 20172018 tax years generally remain open and subject to examination by the state tax authorities and foreign tax authorities. We are currently under examination by the IRS for the tax years 2011 through the period ending February 2016. We are under audit by the Indian Tax Authority for the 2014 and 2017 tax years. We are currently under audit by the California Franchise Tax Board for the 2012 through 2014 tax years. We were notified in December 2017January 2019 that the Swiss Tax AuthoritiesMassachusetts Department of Revenue would audit the 20142015 through February 2016 tax years. This audit concluded in April 2018 with no adjustments. We are not currently under audit in any other taxing jurisdictions.
On July 24, 2018, U.S. Court of Appeals for the Ninth Circuit reversed the decision of the U.S. Tax Court in Altera Corp. v. Commissioner related to the treatment of stock-based compensation in an intercompany cost sharing arrangement. On August 7, 2018, the Ninth Circuit withdrew the opinion to allow time for a reconstituted panel to confer on this appeal. UntilDue to the reconstituted

As of September 30, 2018,being overturned upon appeal, we have not recorded any tax benefit or expense as of excluding stock-based compensation fromMarch 31, 2019. We will continue to monitor ongoing developments and potential impacts to our cost sharing agreement.consolidated financial statements.
12.8. Commitments and Contingencies
Take Private Deferred Stock Payments
As a result of the Take Private, RSUs granted to certain of our employees under the existing stock plans not subject to accelerated vesting were cancelled and converted into the right to receive the per share price of $60.10 less applicable withholding taxes shortly after those RSUs would have vested based on the underlying original RSU vesting schedule and subject to continued employment of the holders of those RSUs. As of September 30, 2018, we had a liability for Take Private deferred stock payments recorded of $1.8 million included in accrued liabilities and other, related to the future payment for service provided. For the nine months ended September 30, 2018, we recognized $2.4 million of compensation expense and made cash payments of approximately $3.5 million to employees related to the deferred compensation. We expect to pay approximately $4.2 million through the year 2020. The expected future payment may differ from actual payment amounts due to future employee terminations.
Legal Proceedings
From time to time, we have been and may be involved in various legal proceedings arising in our ordinary course of business. In the opinion of management, resolution of any pending claims (either individually or in the aggregate) is not expected to have a material adverse impact on our consolidated financial statements, cash flows or financial position and it is not possible to provide an estimated amount of any such loss. However, the outcome of disputes is inherently uncertain. Therefore, although management considers the likelihood of such an outcome to be remote, an unfavorable resolution of one or more matters could materially affect our future results of operations or cash flows, or both, in a particular period.
13.9. Subsequent Events
Initial Public OfferingAcquisition
In October 2018,On April 30, 2019, we completed our IPO, in which we sold and issued 25,000,000 shares of our common stock atacquired SAManage Ltd., or Samanage, an issue price of $15.00 per share. We raised a total of $375.0IT service desk solution company, for approximately $350.0 million, in gross proceeds from the offering, or approximately $353.0$329.0 million, net of cash acquired. Samanage is based in net proceeds after deducting underwriting discountsCary, North Carolina. By acquiring Samanage, we entered the IT Service Management, or ITSM, market and commissionsintroduced the Samanage SaaS-based IT Service Desk products into our product portfolio. We funded the transaction with cash on hand and $35.0 million of $17.8 millionborrowings under our Revolving Credit Facility.
The transaction will be accounted for using the acquisition method of accounting. Accordingly, the results of operations of Samanage since the acquisition date will be included in our condensed consolidated financial statements for the second quarter of 2019. We are in the process of gathering information to allocate the purchase price to the assets acquired and estimated offering-related expenses of approximately $4.2 million. A portionliabilities assumed. All of the net proceeds fromassets acquired and liabilities assumed in the offering were used to repay the $315.0 million in borrowings outstanding under our Second Lien Term Loan. In connection with the voluntary prepayment of the Second Lien Term Loan, we paid a $14.2 million prepayment fee.
Upon the closing of our IPO, all 2,661,015 shares of Class A Common Stock that were outstanding immediately prior to the closing of such offering converted into 140,053,370 shares of common stock in accordance with the terms of our certificate of incorporation. In addition, we converted $717.4 million of accrued and unpaid dividends on the Class A Common Stock into 37,758,109 shares of common stock equal to the result of the accrued and unpaid dividends on each share of Class A Common Stock, divided by $19.00 per share. All outstanding shares of Class B Common Stock converted into common stock on a one-for-one basis.
Following consummation of our IPO, we amended our certificate of incorporation to, among other things, set the authorized capital stock of the companytransaction will be recognized at 1,000,000,000 shares of common stock, par value of $0.001 per share, and 50,000,000 shares of preferred stock, par value of $0.001 per share. Each share of common stock entitles the holder thereof to one vote on each matter submitted to a vote at any meeting of stockholders.
2018 Equity Incentive Plan
In October 2018, the board of directors adopted, and the stockholders approved, the SolarWinds Corporation 2018 Equity Incentive Plan, or 2018 Plan. We reserved 30,000,000 shares of our common stock for issuance under the 2018 Plan. On October 27, 2018, we granted 7,342,878 equity awards to our employees and directors consisting of 6,371,956 restricted stock units, or RSUs, and 970,922 performance stock units, or PSUs. RSUs generally vest over a four-year service period. PSUs generally vest over a three-year period based on the achievement of specified performance targets for the fiscal year ended December 31, 2019 and subject to continued service through the applicable vesting dates. Based on the extent to which the performance targets are achieved, vested shares may range from 0% to 150% of the target award amount. We will not grant any additional awards under our 2016 Plan; however, the 2016 Plan will continue to govern the terms and conditions of all outstanding equity awards granted under the 2016 Plan.

The new product, SolarWinds Threat Monitor, is an automated tool that is designed to reduce the complexity of threat detection for IT operations teams as well as for MSPs and MSSPs (Managed Security Service Providers).

Initial Public Offering
Take Private. In October 2018, we completed our initial public offering, or IPO, in which we sold and issued 25,000,000 shares of our common stock at an issue price of $15.00 per share. We raised a total of $375.0 million in gross proceeds from the offering, or approximately $353.0 million in net proceeds after deducting underwriting discounts and commissions of $17.8 million and estimated offering-related expenses of approximately $4.2 million.proceeds. A portion of the net proceeds from the offering were used to repay the $315.0 million in borrowings outstanding under our Second Lien Term Loan. In connection withsecond lien term loan.
First Quarter Financial Highlights
Our approach, which we call the voluntary prepayment“SolarWinds Model,” is based on our commitment to building a business that is focused on growth and profitability. Below are our key financial highlights for the three months ended March 31, 2019 as compared to the three months ended March 31, 2018.
Revenue
Our total revenue was $215.8 million and $196.9 million for the three months ended March 31, 2019 and 2018, respectively. Our non-GAAP total revenue was $215.8 million and $198.4 million for the three months ended March 31, 2019 and 2018, respectively. Recurring revenue, which consists of subscription and maintenance revenue, represented approximately 82% of our total revenue for the three months ended March 31, 2019. We have increased our recurring revenue as a result of the Second Lien Term Loan,growth in our subscription sales and the continued growth of our maintenance revenue.
Profitability
We have grown while maintaining high levels of operating efficiency. Our net income for the three months ended March 31, 2019 was $3.1 million compared to a net loss of $59.9 million for the three months ended March 31, 2018. Our Adjusted EBITDA was $104.8 million and $95.1 million for the three months ended March 31, 2019 and 2018, respectively.
Cash Flow
We are building our business to generate strong cash flow over the long term. For the three months ended March 31, 2019 and 2018, cash flows from operations were $63.4 million and $35.4 million, respectively. During those periods, our cash flows from operations were reduced by cash payments for interest on our long-term debt of $25.4 million and $48.7 million, respectively.

Acquisition
Subsequent to the end of the first quarter, on April 30, 2019, we paid a $14.2acquired SAManage Ltd., or Samanage, an IT service desk solution company, for approximately $350.0 million, prepayment fee.

We funded the transaction with cash on hand and $35.0 million of Part I of this Quarterly Report on Form 10-Q for additional information regardingborrowings under our IPO.Revolving Credit Facility.
Components of Our Results of Operations
Revenue
Our revenue consists of recurring revenue and perpetual license revenue.
Recurring Revenue. The significant majority of our revenue is recurring and consists of subscription and maintenance revenue.
Subscription Revenue. We primarily derive subscription revenue from fees received for subscriptions to our SaaS offerings, and to a lesser extent, our time-based license arrangements. Subscriptions revenue includes sales of our cloud management and MSP products. SubscriptionWe generally recognize revenue is recognized ratably over the subscription term after all revenue recognition criteriaonce the service is made available to the customer or when we have been met.the right to invoice for services performed. We generally invoice subscription agreements monthly in arrears based on usage or monthly in advance over the subscription period. Our subscription revenue grows as customers add new subscription products, upgrade the capacity level of their existing subscription products or increase the usage of their subscription products. Our revenue from MSP products increases with the addition of end customers served by our MSP customers, the proliferation of devices managed by those MSPs and the expansion of products used by those MSPs to manage end customers’ IT infrastructures.
Maintenance Revenue. We derive maintenance revenue from the sale of maintenance services associated with our perpetual license products. Perpetual license customers pay for maintenance services based on the products they have purchased. We recognize maintenance revenue ratably on a daily basis over the contract period. Our maintenance revenue grows when we renew existing maintenance contracts and add new perpetual license customers, and as existing customers add new products. Customers typically renew their maintenance contracts at our standard list maintenance renewal pricing for their applicable products. We generally invoice maintenance contracts annually in advance.
License Revenue. We derive license revenue from sales of perpetual licenses of our products to new and existing customers. We include one year of maintenance services as part of our customers’ initial license purchase. License revenue is recognized at a point in time upon delivery of the electronic license key. We calculate the amount of revenue allocated to the license by subtractingestimating our standalone selling prices utilizing the fair value, which is determinedresidual approach by considering our standard maintenance renewal price list, of the applicable maintenance services from the total invoice or contract amount. If we increase list prices for maintenance services without increasing prices by a similar percentage for perpetual licenses, the amount of license revenue we recognize at the time of the sale of the perpetual license could be adversely affected.pricing and discounting practices.
Cost of Revenue
Cost of Recurring Revenue. Cost of recurring revenue consists of technical support personnel costs, royalty fees, hosting fees and an allocation of overhead costs for our subscription revenue and maintenance services. Allocated costs consist of certain facilities, depreciation, benefits recruiting and IT costs allocated based on headcount.
Amortization of Acquired Technologies. We amortize to cost of revenue the capitalized costs of technologies acquired in connection with the Take Private and our other acquisitions.
Operating Expenses
Operating expenses consists of sales and marketing, research and development and general and administrative expenses as well as amortization of acquired intangibles. Personnel costs are the most significant component of operating expenses and consist of salaries, benefits, bonuses, sales commissions, stock-based compensation, contractor fees and contractor fees.an allocation of overhead costs based on headcount. The total number of employees as of March 31, 2019 was 2,794, as compared to 2,483 as of March 31, 2018. In connection with our IPO in October 2018, we granted equity awards to our employees and directors consisting of restricted stock units and performance stock units resulting in an increase in stock-based compensation expense in the periods subsequent to the IPO.
Sales and Marketing. Sales and marketing expenses primarily consist of related personnel costs, including our sales, marketing and maintenance renewal and subscription retention teams. Sales and marketing expenses also includes the

cost of digital marketing programs such as paid search, search engine optimization and management, website maintenance and design. We expect to continue to hire personnel globally to drive new sales and maintenance renewals.
Research and Development. Research and development expenses primarily consist of related personnel costs. We expect to continue to grow our research and development organization, particularly internationally.

General and Administrative. General and administrative expenses primarily consist of personnel costs for our executive, finance, legal, human resources and other administrative personnel, general restructuring charges and other acquisition-related costs, professional fees and other general corporate expenses. SinceIn the periods after the Take Private and prior to our IPO, these expenses have also included management fees payable to our Sponsors, thatwhich were eliminated upon the completion of our initial public offering.
Amortization of Acquired Intangibles. We amortize to operating expenses the capitalized costs of intangible assets acquired in connection with the Take Private and our other acquisitions.
Other Income (Expense)
Other income (expense) primarily consists of interest expense, gains (losses) resulting from changes in exchange rates on foreign currency denominated intercompany loans and accounts, and losses on extinguishment of debt. We expect interest expense to decrease following the completion of our initial public offering as we repay indebtedness.
We established a foreign currency denominated intercompany loan as part of the Take Private to provide a conduit to utilize foreign earnings effectively. Until any cash payments are made with respect to this loan, theThe gains (losses) associated with the changes in exchange rates on amounts borrowed are unrealized non-cash events. Substantially all of these unrealized amounts are related to this one foreign currency denominated loan. As of July 1, 2018, this foreign currency denominated intercompany loan was designated as long-term due to a change in our investment strategy and the new Tax Act. Therefore, beginning on July 1, 2018, the foreign currency transaction gains and losses resulting from remeasurement are recognized as a component of accumulated other comprehensive income (loss).
Foreign Currency
As a global company, we face exposure to adverse movements in foreign currency exchange rates. Fluctuations in foreign currencies impact the amount of total assets, liabilities, revenue, operating expenses and cash flows that we report for our foreign subsidiaries upon the translation of these amounts into U.S. dollars. See “Item 3: Quantitative and Qualitative Disclosures About Market Risk for additional information on how foreign currency impacts our financial results.
Income Tax Expense
Income tax expense consists of domestic and foreign corporate income taxes related to the sale of products. The tax rate on income earned by our North American entities is higher than the tax rate on income earned by our international entities.entities other than Canada and Sweden. We expect the income earned by our international entities to grow over time as a percentage of total income, which may result in a decline in our effective income tax rate. However, our effective tax rate will be affected by many other factors including changes in tax laws, regulations or rates, new interpretations of existing laws or regulations, shifts in the allocation of income earned throughout the world and changes in overall levels of income before tax.

In the first quarter of 2019, we adopted FASB Accounting Standards Codification (ASC) No. 2014-09 “Revenue from 35%Contracts with Customers,” or ASC 606, which replaced all existing revenue guidance under ASC 605 “Revenue Recognition,”

including prescriptive industry-specific guidance, or ASC 605. We adopted ASC 606 using the modified-retrospective method therefore, results for the first quarter of 2019 are presented in compliance with ASC 606 and historical financial results for reporting periods prior to 21%, requires companies to pay a one-time transition tax on earnings of certain foreign subsidiaries that2019 are presented in conformity with amounts previously disclosed under ASC 605. Total revenue for the three months ended March 31, 2019 would have not been taxed previously in the U.S. and creates new taxes on certain foreign sourced earnings. For additional discussion about our income taxes, seeapproximately $0.2 million higher under ASC 605. See Note 11. Income Taxes 2. Summary of Significant Accounting Policiesin the Notes to Condensed Consolidated Financial Statements included in Item 1 of Part I of this Quarterly Report on Form 10-Q.10-Q, for a full description of implementation impact of ASC 606 including the presentation of financial results for the three month period ended March 31, 2019 under ASC 605 for comparison to the prior year period.

Our revenue recognized in the first quarter of 2018 is impacted by our accounting for acquisitions, including the Take Private. We account for acquired businesses using the acquisition method of accounting, which requires the assets acquired and liabilities assumed, including deferred revenue, be recorded at the date of acquisition at their respective fair values which could differ from the historical book values. In most cases, adjusting the acquired deferred revenue balances to fair value on the date of acquisition had the effect of reducing the historical deferred revenue balance and therefore reducing the revenue recognized in subsequent periods. The impact of the purchase accounting adjustments to revenue is excluded in the calculation of our non-GAAP financial measures, see “Non-GAAP Financial Measures” below for further discussion. Our revenue for the first quarter of 2019 was not impacted by this adjustment. The impact to revenue as a result of purchase accounting adjustments during the relevant periodsfirst quarter of 2018 were as follows:

Total revenue increased $24.2$18.9 million, or 12.8%9.6%, for the three months ended September 30, 2018March 31, 2019 compared to the three months ended September 30, 2017.March 31, 2018. Revenue from North America was approximately 64% and 67%65% of total revenue for both the three months ended September 30, 2018March 31, 2019 and 2017, respectively.2018. Other than the United States, no single country accounted for 10% or more of our total revenue during these periods. 
Recurring Revenue
Subscription Revenue. Subscription revenue increased $12.4$8.5 million, or 22.3%13.5%, for the three months ended September 30, 2018March 31, 2019 compared to the three months ended September 30, 2017,March 31, 2018, primarily due to sales of additional cloud management and MSP products. These increases were partially offset by the effect of the weakening of most foreign currencies relative to the U.S. dollar. Our subscription revenue increased slightly as a percentage of our total revenue for the three months ended September 30, 2018March 31, 2019 compared to the three months ended September 30, 2017.March 31, 2018. Subscription revenue for the three months ended March 31, 2019 would have been approximately $0.1 million higher under ASC 605. See Note 2. Summary of Significant Accounting Policies in the Notes to Condensed Consolidated Financial Statements in Item 1 of Part I of this Quarterly Report on Form 10-Q, for a full discussion of the impact of ASC 606 on our revenue for the three months ended March 31, 2019.
Our net retention rate for our subscription products was approximately 105% the trailing twelve-month period ended March 31, 2019. We define our net retention rate for subscription products as the implied monthly subscription revenue at the end of a period for the base set of customers from which we generated subscription revenue in the year prior to the calculation, divided by the implied monthly subscription revenue one year prior to the date of calculation for that same customer base.
Maintenance Revenue. Maintenance revenue increased $8.6$9.3 million, or 9.2%9.6%, for the three months ended September 30, 2018March 31, 2019 compared to the three months ended September 30, 2017.March 31, 2018. Of this change, $7.6$8.5 million was attributable to a growing maintenance renewal customer base from sales of our perpetual license products and strong maintenance renewal rates, inpartially offset by the low-effect of the weakening of most foreign currencies relative to mid-90 percent range.the U.S. dollar. The remaining $1.0$0.8 million increase was attributable to a smallerthe purchase accounting adjustment to deferred revenue in the three months ended September 30, 2018 as compared toMarch 31, 2018. Maintenance revenue for the three months ended September 30, 2017.March 31, 2019 would have been approximately $0.2 million higher under ASC 605. See Note 2. Summary

of Significant Accounting Policies in the Notes to Condensed Consolidated Financial Statements in Item 1 of Part I of this Quarterly Report on Form 10-Q, for a full discussion of the impact of ASC 606 on our revenue for the three months ended March 31, 2019.
Our maintenance renewal rate was approximately 97% for the trailing twelve-month period ended March 31, 2019. We define our maintenance renewal rate as the sales of maintenance services for all existing maintenance contracts expiring in a period, divided by the sum previous sales of maintenance services corresponding to those services expiring in the current period. Sales of maintenance services includes sales of maintenance renewals for a previously purchased product and the amount allocated to maintenance revenue from a license purchase.
License Revenue
License revenue increased $3.3$1.1 million, or 8.0%2.9%, due to increased sales of our licensed products in each of our North American and international locations. We believe our more tenured sales and marketing leadership teams, particularly in our international regions, during 2018 was primarilylocations, partially offset by the reasoneffect of the weakening of most foreign currencies relative to the U.S. dollar. License revenue for the increased growththree months ended March 31, 2019 would have been approximately $0.2 million lower under ASC 605. See Note 2.

Total cost of revenue increased in the three months ended September 30, 2018March 31, 2019 compared to the three months ended September 30, 2017March 31, 2018 primarily due to increases in personnel costs of $1.1 million to support new customers and additional product offerings royalty and hosting fees related to our subscription products of $1.0$0.7 million, which includes a $0.4 million increase in stock-based compensation expense, and depreciation and other amortization of $0.8$0.4 million. In addition,These increases were partially offset by a decrease in amortization of acquired technologies increased $0.3of $0.5 million. Amortization of acquired technologies includes $41.3$41.0 million and $41.4$41.8 million of amortization related to the Take Private for the three months ended September 30,March 31, 2019 and 2018, and three months ended September 30, 2017, respectively, with the remaining balance related primarily to the LOGICnow acquisition in May 2016.

Sales and Marketing. Sales and marketing expenses increased $6.0$7.9 million, or 11.7%15.0%, primarily due to increases in personnel costs of $5.8$4.6 million, which includes an increase of $2.8 million in stock-based compensation expense, and marketing program costs of $0.5$2.4 million. We increased our sales and marketing employee headcount to support the sales of additional products and growth in the business. Sales and marketing expense for the three months ended March 31, 2019 would have been approximately $1.4 million higher under ASC 605 due to the impact of the capitalization and amortization of commission expense under ASC

606. See Note 2. Summary of Significant Accounting Policies in the Notes to Condensed Consolidated Financial Statements in Item 1 of Part I of this Quarterly Report on Form 10-Q for further discussion of the impact of the adoption of ASC 606.
Research and Development. Research and development expenses increased $2.8$0.4 million, or 13.4%1.8%, primarily due to an increase in personnel costs of $3.7$1.3 million offset by reductions in acquisition and Take Private related costs of $0.6 million and contract services of $0.2 million. The increase in personnel costs is primarily related to an increase in stock-based compensation expense of $1.7 million. We increasedcontinue to increase our worldwide research and development employee headcount to expedite delivery of product enhancements and new product offerings to our customers. This increase was offset by reductions in acquisition and Take Private related costs of $0.6 million and contract services of $0.3 million.
General and Administrative. General and administrative expenses increased $4.5$2.6 million, or 30.0%13.3%, primarily due to a $3.1 millionan increase in personnel costs to support the growth of the business,$3.4 million, which includes an increase of $2.9 million in stock-based compensation expense, and a $1.1$1.4 million increase in professional fees and other offering costspublic company costs. These increases were partially offset by a reduction of $2.5 million related to management fees payable to our IPO.Sponsors that were eliminated upon the completion of our initial public offering in October 2018.
Amortization of Acquired Intangibles. Amortization of acquired intangibles decreased $0.5$0.6 million, or 3.1%3.7%, for the three months ended September 30, 2018March 31, 2019 compared to the three months ended September 30, 2017.March 31, 2018. Amortization of intangible assets includes $11.9 million and $12.7$12.4 million of amortization related to the Take Private for the three months ended September 30,March 31, 2019 and 2018, and 2017, respectively, with the remaining balance related primarily to the LOGICnow acquisition in May 2016.

The decrease in interest expense is due to the repayment of $315.0 million in outstanding borrowings under our second lien term loan in October 2018 and the reduction in the interest rate spread under our credit facilities resulting from the refinancing transaction we completed in March 2018 and our IPO in October 2018.

As of July 1, 2018, we changed our assertion regarding the planned settlement of a certain intercompany loan. We have evaluated our investment strategy in light of our global treasury plans and the new Tax Act and have determined there is no need to settle the principal related to the loan. Therefore, beginning on July 1, 2018, the foreign currency transaction gains

and losses resulting from the remeasurement of this long-term intercompany loan denominated in a currency other than the subsidiary's functional currency are recognized as a component of accumulated other comprehensive income (loss) and not included in other income (expense), net.

Our revenue recognized is impacted by our accounting for acquisitions, including the Take Private. We account for acquired businesses using the acquisition method of accounting, which requires the assets acquired and liabilities assumed, including deferred revenue, be recorded at the date of acquisition at their respective fair values which could differ from the historical book values. In most cases, adjusting the acquired deferred revenue balances to fair value on the date of acquisition had the effect of reducing the historical deferred revenue balance and therefore reducing the revenue recognized in subsequent periods. The impact to revenue as a result of purchase accounting adjustments during the relevant periods were as follows:

Total revenue increased $82.2 million, or 15.5%, for the nine months ended September 30, 2018 compared to the nine months ended September 30, 2017. Revenue from North America was approximately 65% and 67% of total revenue for the nine months ended September 30, 2018 and 2017, respectively. Other than the United States, no single country accounted for 10% or more of our total revenue during these periods. 
Recurring Revenue
Subscription Revenue. Subscription revenue increased $40.6 million, or 26.1%, for the nine months ended September 30, 2018 compared to the nine months ended September 30, 2017, primarily due to sales of additional cloud management and MSP products. Our subscription revenue increased as a percentage of our total revenue for the nine months ended September 30, 2018 compared to the nine months ended September 30, 2017.
Maintenance Revenue. Maintenance revenue increased $36.1 million, or 13.8%, for the nine months ended September 30, 2018 compared to the nine months ended September 30, 2017. Of this change, $27.9 million was attributable to a growing maintenance renewal customer base from sales of our perpetual license products and maintenance renewal rates in the low- to mid-90 percent range. The remaining $8.2 million increase was attributable to a smaller purchase accounting adjustment to deferred revenue in the nine months ended September 30, 2018 as compared to the nine months ended September 30, 2017.
License Revenue
License revenue increased $5.5 million, or 4.9%, due to increased sales of our licensed products, particularly in our international locations. We believe our more tenured sales and marketing leadership teams in international regions during 2018 was primarily the reason for the increased growth in these regions.

Sales and Marketing. Sales and marketing expenses increased $14.0 million, or 9.2%, primarily due to increases in personnel costs of $13.3 million and marketing program costs of $0.9 million. We increased our sales and marketing employee headcount to support the sales of additional products and growth in the business.
Research and Development. Research and development expenses increased $8.4 million, or 13.2%, primarily due to an increase in personnel costs of $10.7 million. We increased our worldwide research and development employee headcount to expedite delivery of product enhancements and new product offerings to our customers. This increase was offset by reductions in contract services of $1.2 million and acquisition and Take Private related costs of $1.1 million.
General and Administrative. General and administrative expenses increased $9.0 million, or 17.7%, primarily due to a $9.1 million increase in personnel costs to support the growth of the business, a $2.3 million increase in offering costs related to our IPO and other professional fees. These increases were partially offset by a lease abandonment charge of $1.7 million in the nine months ended September 30, 2017 that did not reoccur in the nine months ended September 30, 2018 and a decrease of acquisition and Take Private related costs of $1.5 million.
Amortization of Acquired Intangibles. Amortization of acquired intangibles increased $0.4 million, or 0.8%, for the nine months ended September 30, 2018 compared to the nine months ended September 30, 2017 due to the addition of intangible assets related to acquisitions. Amortization of intangible assets includes $36.3 million and $37.7 million of amortization related to the Take Privatefor the nine months ended September 30, 2018 and September 30, 2017, respectively, with the remaining balance related primarily to the LOGICnow acquisition in May 2016.

Our income tax benefit for the nine months ended September 30, 2018 increased by $7.6 million as compared to the nine months ended September 30, 2017 primarily as a result of an increase in the loss before income taxes for the period offset by a lower U.S. corporate tax rate attributable to the Tax Act. For additional discussion about our income taxes, see Note 11. Income Taxes in the Notes to Consolidated Financial Statements included in Item 1 of Part I of this Form 10-Q.

Non-GAAP Financial Measures
In addition to financial measures prepared in accordance with GAAP, we use certain non-GAAP financial measures to clarify and enhance our understanding, and aid in the period-to-period comparison, of our performance. We believe that these non-GAAP financial measures provide supplemental information that is meaningful when assessing our operating performance because they exclude the impact of certain amounts that our management and board of directors do not consider part of core operating results when assessing our operational performance, allocating resources, preparing annual budgets and determining compensation. Accordingly, these non-GAAP financial measures may provide insight to investors into the motivation and decision-making of management in operating the business. Set forth in the first table below are the corresponding GAAP financial measures for each non-GAAP financial measure. Investors are encouraged to review the reconciliation of each of these non-GAAP financial measures to its most comparable GAAP financial measure included below.
While we believe that these non-GAAP financial measures provide useful supplemental information, non-GAAP financial measures have limitations and should not be considered in isolation from, or as a substitute for, their most comparable GAAP measures. These non-GAAP financial measures are not prepared in accordance with GAAP, do not reflect a comprehensive system of accounting and may not be comparable to similarly titled measures of other companies due to potential differences in their financing and accounting methods, the book value of their assets, their capital structures, the method by which their assets were acquired and the manner in which they define non-GAAP measures. Items such as the amortization of intangible assets, stock-based compensation expense, acquisition related adjustments and restructuring charges, as well as the related tax impacts of these items can have a material impact on our GAAP financial results.
Non-GAAP Revenue
We define non-GAAP subscription revenue, non-GAAP maintenance revenue, non-GAAP license revenue and non-GAAP total revenue, as subscription revenue, maintenance revenue, license revenue and total revenue, respectively, excluding the impact of purchase accounting. We monitor these measures to assess our performance because we believe our revenue growth rates would be overstated without these adjustments. We believe presenting non-GAAP subscription revenue, non-GAAP maintenance revenue, non-GAAP license revenue and non-GAAP total revenue aids in the comparability between periods and in assessing our overall operating performance.

Non-GAAP Operating Income and Non-GAAP Operating Margin
We provide non-GAAP operating income and related non-GAAP margin using non-GAAP revenue as discussed above and excluding such items as the write-down of deferred revenue related to purchase accounting, amortization of acquired intangible assets, stock-based compensation expense, acquisition and Sponsor related costs and restructuring charges and other. Management believes these measures are useful for the following reasons:
Amortization of Acquired Intangible Assets. We provide non-GAAP information that excludes expenses related to purchased intangible assets associated with our acquisitions. We believe that eliminating this expense from our non-GAAP measures is useful to investors, because the amortization of acquired intangible assets can be inconsistent in amount and frequency and is significantly impacted by the timing and magnitude of our acquisition transactions, which also vary in frequency from period to period. Accordingly, we analyze the performance of our operations in each period without regard to such expenses.
Stock-Based Compensation Expense. We provide non-GAAP information that excludes expenses related to stock-based compensation. We believe that the exclusion of stock-based compensation expense provides for a better comparison of our operating results to prior periods and to our peer companies as the calculations of stock-based compensation vary from period to period and company to company due to different valuation methodologies, subjective assumptions and the variety of award types. Because of these unique characteristics of stock-based compensation, management excludes these expenses when analyzing the organization’s business performance.
Acquisition and Sponsor Related Costs. We exclude certain expense items resulting from the Take Private and other acquisitions, such as legal, accounting and advisory fees, changes in fair value of contingent consideration, costs related to integrating the acquired businesses, deferred compensation, severance and retention expense. We consider these adjustments, to some extent, to be unpredictable and dependent on a significant number of factors that are outside of our control. Furthermore, acquisitions result in operating expenses that would not otherwise have been incurred by us in the normal course of our organic business operations. We believe that providing these non-GAAP measures that exclude acquisition and Sponsor related costs, allows users of our financial statements to better review and understand the historical and current results of our continuing operations, and also facilitates comparisons to our historical results and results of less acquisitive peer companies, both with and without such adjustments.
Restructuring Charges and Other. We provide non-GAAP information that excludes restructuring charges such as severance and the estimated costs of exiting and terminating facility lease commitments, as they relate to our corporate restructuring and exit activities.activities and charges related to the separation of employment with executives of the Company. These restructuring charges are inconsistent in amount and are significantly impacted by the timing and nature of these events. Therefore,

although we may incur these types of expenses in the future, we believe that eliminating these charges for purposes of calculating the non-GAAP financial measures facilitates a more meaningful evaluation of our operating performance and comparisons to our past operating performance.

Adjusted EBITDA and Adjusted EBITDA Margin
We regularly monitor adjusted EBITDA, as it is a measure we use to assess our operating performance. We define adjusted EBITDA as net income or loss, excluding the impact of purchase accounting on total revenue, amortization of acquired intangible assets and developed technology, depreciation expense, stock-based compensation expense, restructuring and other charges,

acquisition and Sponsor related costs, interest expense, net, debt extinguishment and refinancing costs, unrealized foreign currency (gains) losses, and income tax expense (benefit). We define adjusted EBITDA margin as adjusted EBITDA divided by non-GAAP revenue. Adjusted EBITDA has limitations as an analytical tool, and you should not consider it in isolation or as a substitute for analysis of our results as reported under GAAP. Some of these limitations are: although depreciation and amortization are non-cash charges, the assets being depreciated and amortized may have to be replaced in the future, and adjusted EBITDA does not reflect cash capital expenditure requirements for such replacements or for new capital expenditure requirements; adjusted EBITDA excludes the impact of the write-down of deferred revenue due to purchase accounting in connection with our acquisition, and therefore includes revenue that will never be recognized under GAAP; adjusted EBITDA does not reflect changes in, or cash requirements for, our working capital needs; adjusted EBITDA does not reflect the significant interest expense, or the cash requirements necessary to service interest or principal payments, on our debt; adjusted EBITDA does not reflect tax payments that may represent a reduction in cash available to us; and other companies, including companies in our industry, may calculate adjusted EBITDA differently, which reduces its usefulness as a comparative measure.

Because of these limitations, you should consider adjusted EBITDA alongside other financial performance measures, including net income (loss) and our other GAAP results. In evaluating adjusted EBITDA, you should be aware that in the future we may incur expenses that are the same as or similar to some of the adjustments in this presentation. Our presentation of adjusted EBITDA should not be construed as an inference that our future results will be unaffected by the types of items excluded from the calculation of adjusted EBITDA. Adjusted EBITDA is not a presentation made in accordance with GAAP and the use of the term varies from others in our industry.

Liquidity and Capital Resources
Cash and cash equivalents were $278.3$434.5 million as of September 30, 2018.March 31, 2019. Our international subsidiaries held approximately $129.9$106.4 million of cash and cash equivalents, of which 73.7%77.2% were held in Euros. The Tax Act imposes a mandatory transition tax on accumulated foreign earnings and eliminates U.S. federal income taxes on foreign subsidiary distribution. Effective January 1, 2018, we began recognizing the tax impact of including certain foreign earnings in U.S. taxable income as a period cost. We intend either to invest our foreign earnings permanently in foreign operations or to remit these earnings to our U.S. entities in a tax-free manner. For this reason, we have not recognized deferred income taxes for local country income and withholding taxes that could be incurred on distributions of certain foreign earnings or for outside basis differences in our subsidiaries.
Our primary source of cash for funding operations and growth has been through cash provided by operating activities. We believe that our existing cash and cash equivalents, our cash flows from operating activities and our borrowing capacity under our credit facilities will be sufficient to fund our operations, fund required debt repayments and meet our commitments for capital expenditures for at least the next 12 months.

In October 2018,On April 30, 2019, we completed our IPO, in which we sold and issued 25,000,000 shares of our common stock atacquired SAManage Ltd., or Samanage, an issue price of $15.00 per share. We raised a total of $375.0IT service desk solution company, for approximately $350.0 million, in gross proceeds from the offering, or approximately $353.0$329.0 million, in net proceeds after deducting underwriting discountsof cash acquired. We funded the transaction with cash on hand and commissions$35.0 million of $17.8 million and estimated offering-related expenses of approximately $4.2 million. A portion of the net proceeds from the offering were used to repay the $315.0 million in borrowings outstanding under our Second Lien Term Loan. In connection with the voluntary prepayment of the Second Lien Term Loan, we paid a $14.2 million prepayment fee. See Note 13. Subsequent Events in the Notes to Condensed Consolidated Financial Statements in Item 1 of Part I of this Quarterly Report on Form 10-Q for additional information regarding our IPO.Revolving Credit Facility.
Although we are not currently a party to any material definitive agreement regarding potential investments in, or acquisitions of, complementary businesses, applications or technologies, we may enter into these types of arrangements, which could reduce our cash and cash equivalents, require us to seek additional equity or debt financing or repatriate cash generated by our international operations that could cause us to incur withholding taxes on any distributions. Additional funds from financing arrangements may not be available on terms favorable to us or at all.
Indebtedness
As of September 30, 2018,March 31, 2019, our total indebtedness was $2.3$2.0 billion, with up to $125.0 million of available borrowings under our revolving credit facility. See Note 6.4. Debt in the Notes to Condensed Consolidated Financial Statements included in Item 1 of Part I of this Form 10-Q for additional information regarding our debt. In addition, see Note 9. Subsequent Eventsin the Notes to Condensed Consolidated Financial Statements included in Item 1 of Part I of this Form 10-Q for additional information regarding

the $35.0 million of borrowings made under our Revolving Credit Facility in connection with the acquisition of Samanage in April 2019.
First Lien Credit Agreement
On March 15, 2018, or the Refinancing Date, we entered into Amendment No. 4 to First Lien Credit Agreement, originally dated as of February 5, 2016.
The First Lien Credit Agreement, as amended, provides for a senior secured revolving credit facility in an aggregate principal amount of $125.0 million, or the Revolving Credit Facility, consisting of a $25.0 million U.S. dollar revolving credit facility, or the U.S. Dollar Revolver, and a $100.0 million multicurrency revolving credit facility, or the Multicurrency Revolver. The Revolving Credit Facility includes a $35.0 million sublimit for the issuance of letters of credit. The First Lien Credit Agreement also contains a term loan facility (which we refer to as the First Lien Term Loan, and together with the Revolving Credit Facility, as the First Lien Credit Facilities) in an original aggregate principal amount of $1,990.0 million.
The First Lien Credit Agreement provides us the right to request additional commitments for new incremental term loans and revolving loans, in an aggregate principal amount not to exceed (a) the greater of (i) $400.0 million and (ii) 100% of our consolidated EBITDA, as defined in the First Lien Credit Agreement (calculated on a pro forma basis), for the most recent four fiscal quarter period, or the First Lien Fixed Basket, minusplus (b) the amount of any incremental loans incurred under the Second Lien Fixed Basket (as defined below), plus (c) the amount of certain voluntary prepayments of the First Lien Credit Facilities, plus (d)(c) an unlimited amount subject to pro forma compliance with a first lien net leverage ratio not to exceed 4.75 to 1.00.
Under the U.S. Dollar Revolver, $7.5 million of commitments will mature on February 5, 2021, and $17.5 million along with all commitments under the Multicurrency Revolver will mature on February 5, 2022. The First Lien Term Loan will mature on February 5, 2024.
The First Lien Term Loan requires equal quarterly repayments equal to 0.25% of the original principal amount.
Second Lien Credit Facility
On the Refinancing Date, we entered into the Second Lien Credit Agreement with Wilmington Trust, National Association, or Wilmington Trust, as administrative agent and collateral agent, and the other parties thereto. The Second Lien Credit Agreement providesprovided for a term loan facility, or the Second Lien Credit Facility, in an original aggregate principal amount of $315.0 million.
In October 2018, we completed our IPO and used a portion of our net proceeds from the offering to repay the borrowings under our Second Lien Credit Facility.

(1)Represents principal maturities of our Senior Secured First Lien Credit Facility and our Senior Secured Second Lien Floating Rate Note Agreement in effect at December 31, 2017. The estimated cash interest expense is based upon (i) an interest rate of 5.07% on our First Lien and (ii) an interest rate of 10.14% on the Second Lien Notes.
In March 2018, we entered into Amendment No. 4 to First Lien Credit Agreement. In addition, we terminated our Second Lien Notes Agreement and entered into a new Senior Secured Second Lien Credit Agreement. The amounts below reflect the obligations due under these new and amended agreements as of September 30, 2018. The estimated cash interest expense is based upon (i) an interest rate of 5.24% on our First Lien and (ii) an interest rate of 9.49% on our Second Lien.
In October 2018, we completed our IPO and used a portion of our net proceeds from the offering to repay the $315.0 million of borrowings under our Second Lien Credit Facility.

As a result of the Take Private, certain restricted stock units, or RSUs, not subject to accelerated vesting were cancelled and converted into the right to receive the per share price of $60.10 less applicable withholding taxes shortly after those RSUs would have vested based on the underlying original RSU vesting schedule and subject to the continued employment of the holders of those RSUs. See Note 12. Commitments and Contingenciesin the Notes to Condensed Consolidated Financial Statements included in Item 1 of Part I of this Quarterly Report on Form 10-Q for additional details.
(5)
Represents the provisional one–time transition tax as a result of the Tax Act which we have elected to pay over eight years. See Note 11. Income Taxes in the Notes to Condensed Consolidated Financial Statements included in Item 1 of Part I of this Quarterly Report on Form 10-Q for additional details of the impact of the Tax Act.
(6)Other long-term obligations on our balance sheet at December 31, 2017 included non-current income tax liabilities of $22.5 million, which related primarily to unrecognized tax benefits. We have not included this amount in the table above because we cannot reasonably estimate the period during which this obligation may be incurred, if at all.

Critical Accounting Policies and Estimates
Our condensed consolidated financial statements are prepared in conformity with GAAP and require our management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, costs and expenses and related disclosures. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances. Actual results may differ from these estimates, and such estimates may change if the underlying conditions or assumptions change. To the extent that there are differences between our estimates and actual results, our future financial statement presentation, financial condition, results of operations and cash flows will be affected, perhaps materially.
In many cases, the accounting treatment of a particular transaction is specifically dictated by GAAP and does not require management’s judgment in its application, while in other cases, management’s judgment is required in selecting among available alternative accounting standards that allow different accounting treatment for similar transactions. We believe that these accounting policies requiring significant management judgment and estimates are critical to understanding our historical and future performance, as these policies relate to the more significant areas of our financial results. These critical accounting policies are:
the valuation of goodwill, intangibles, long-lived assets and contingent consideration;
revenue recognition;
stock-based compensation;
income taxes; and
loss contingencies.
A full description of our critical accounting policies that involve significant management judgment appears in our final prospectus dated October 18, 2018 and filed withAnnual Report on Form 10-K for the SEC on October 22, 2018 pursuant to Rule 424(b)year ended December 31, 2018. With the exception of the Securities Actchange in our revenue recognition and other related policies upon the adoption of 1933, as amended. Therethe new revenue standard described below, there have been no material changes to our critical accounting policies and estimates since that time.
Revenue Recognition
We generate revenue from fees received for subscriptions, the sale of maintenance services associated with our perpetual license products and the sale of perpetual license products. We recognize revenue related to contracts from customers when we transfer promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This is determined by following a five-step process which includes (1) identifying the contract with a customer, (2) identifying the performance obligations in the contract, (3) determining the transaction price, (4) allocating the transaction price and (5) recognizing revenue when or as we satisfy a performance obligation.

We identify performance obligations in a contract based on the goods and services that will be transferred to the customer that are identifiable from other promises in the contract, or distinct. If not considered distinct, the promised goods or services are combined with other goods or services and accounted for as a combined performance obligation. Determining the distinct performance obligations in a contract requires judgment. Our performance obligations primarily include perpetual and time-based licenses, maintenance support including unspecified upgrades or enhancements to new versions of their software products and subscriptions to our hosted SaaS offerings.
We allocate the transaction price of the contract to each distinct performance obligation based on a relative standalone selling price basis. Determining standalone selling prices for our performance obligations requires judgment and are based on multiple factors including, but not limited to historical selling prices and discounting practices for products and services, internal pricing policies and pricing practices in different regions and through different sales channels. For our subscription products and maintenance services, our standalone selling prices are generally observable using standalone sales or renewals. For our perpetual and time-based license products, we estimate our standalone selling prices utilizing the residual approach by considering our pricing and discounting practices. We review the standalone selling price for our performance obligations periodically and update, if needed, to ensure that the methodology utilized reflects our current pricing practices.
Customers with maintenance agreements are entitled to receive technical support and unspecified upgrades or enhancements to new versions of their software products on a when-and-if-available basis for the specified contract period. We believe that our technical support and unspecified upgrades or enhancements performance obligations each have the same pattern of transfer to the customer and are therefore accounted for as a single distinct performance obligation.
We sell our software products through our direct sales force and through our distributors and other resellers. Our distributors and resellers do not carry inventory of our software and we generally require them to specify the end user of the software at the time of the order.
We account for sales incentives to customers, resellers or distributors as a reduction of revenue at the time we recognize the revenue from the related product sale. We generally deliver licenses and subscriptions directly to the end user whether the customer buys direct or through a reseller or distributor. We report revenue net of any sales tax collected.

Off-Balance Sheet Arrangements
During the ninethree months ended September 30, 2018,March 31, 2019, we did not have any relationships with unconsolidated organizations or financial partnerships, such as structured finance or special purpose entities that would have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes.

Item 3. Quantitative and Qualitative Disclosures About Market Risk
Interest Rate Risk
We had cash and cash equivalents of $278.3$434.5 million and $277.7$382.6 million at September 30, 2018March 31, 2019 and December 31, 2017,2018, respectively. Our cash and cash equivalents consist primarily of bank demand deposits and money market funds. We hold cash, cash equivalents and short-term investments for working capital purposes. Our investments are made for capital preservation purposes, and we do not enter into investments for trading or speculative purposes.
We do not have material exposure to market risk with respect to our cash and cash equivalents, as these consist primarily of highly liquid investments purchased with original maturities of three months or less at September 30, 2018.March 31, 2019.
We had total indebtedness with an outstanding principal balance of $2.3 billion and $2.4$2.0 billion at September 30, 2018March 31, 2019 and December 31, 2017, respectively.2018. Borrowings outstanding under our various credit agreements bear interest at variable rates equal to applicable margins plus specified base rates or LIBOR-based rates with a 1% floor. As of September 30, 2018March 31, 2019 and December 31, 2017,2018, the annual weighted-average rate on borrowings was 5.8%5.25% and 6.5%5.27%, respectively. If there was a hypothetical 100 basis point increase in interest rates, the annual impact to interest expense would be approximately $22.9$19.7 million. This hypothetical change in interest expense has been calculated based on the borrowings outstanding at December 31, 20172018 and a 100 basis point per annum change in interest rate applied over a one-year period.
We do not have material exposure to fair value market risk with respect to our total long-term outstanding indebtedness which consists of $2.3$2.0 billion U.S. dollar term loans as of September 30, 2018,March 31, 2019, not subject to market pricing.

See Note 6.4. Debt and Note 9. Subsequent Eventsin the Notes to Condensed Consolidated Financial Statements in Item 1 of Part I of this Quarterly Report on Form 10-Q for additional information regarding our debt.

Foreign Currency Exchange Risk
As a global company, we face exposure to adverse movements in foreign currency exchange rates. We primarily conduct business in the following locations: the United States, Europe, Canada, South America and Australia. This exposure is the result of selling in multiple currencies, growth in our international investments, additional headcount in foreign countries and operating in countries where the functional currency is the local currency. Specifically, our results of operations and cash flows are subject to fluctuations in the following currencies: the Euro, British Pound Sterling and Australian Dollar against the United States Dollar, or USD. These exposures may change over time as business practices evolve and economic conditions change. Changes in foreign currency exchange rates could have an adverse impact on our financial results and cash flows.
Our condensed consolidated statements of operations are translated into USD at the average exchange rates in each applicable period. Our international revenue, operating expenses and significant balance sheet accounts denominated in currencies other than the USD primarily flow through our United Kingdom and European subsidiaries, which have British Pound Sterling and Euro functional currencies, respectively. This results in a two-step currency exchange process wherein the currencies other than the British Pound Sterling and Euro are first converted into those functional currencies and then translated into USD for our consolidated financial statements. As an example, revenue for sales in Australia is translated from the Australian Dollar to the Euro and then into the USD.
Our statement of operations and balance sheet accounts are also impacted by the re-measurement of non-functional currency transactions such as intercompany loans, cash accounts held by our overseas subsidiaries, accounts receivable denominated in foreign currencies, deferred revenue and accounts payable denominated in foreign currencies. Our foreign currency denominated intercompany loan was established as part of the Take Private to provide a conduit to utilize foreign earnings effectively. The gains (losses) associated with the changes in exchange rates on amounts borrowed are unrealized non-cash events. As of July 1, 2018, the foreign currency denominated intercompany loan is designated as long-term due to a change in our investment strategy and the new Tax Act. Therefore, beginning on July 1, 2018, the foreign currency transaction gains and losses resulting from remeasurement are recognized as a component of accumulated other comprehensive income (loss).
Foreign Currency Transaction Risk
Our foreign currency exposures typically arise from selling annual and multi-year maintenance contracts and subscriptions in multiple currencies, accounts receivable, intercompany transfer pricing arrangements and other intercompany transactions. Our foreign currency management objective is to minimize the effect of fluctuations in foreign exchange rates on selected assets or liabilities without exposing us to additional risk associated with transactions that could be regarded as speculative.
We utilize purchased foreign currency forward contracts to minimize our foreign exchange exposure on certain foreign balance sheet positions denominated in currencies other than the Euro. We do not enter into any derivative financial instruments for trading or speculative purposes. Our objective in managing our exposure to foreign currency exchange rate fluctuations is to reduce the impact of adverse fluctuations in such exchange rates on our earnings and cash flow. The notional amounts and currencies underlying our foreign currency forward contracts will fluctuate period to period as they are principally dependent on the balances of the balance sheet positions that are denominated in currencies other than the Euro held by our global entities. There can be no assurance that our foreign currency hedging activities will substantially offset the impact of fluctuation in currency exchange rates on our results of operations and functional positions. As of September 30, 2018March 31, 2019 and December 31, 2017,2018, we did not have any forward contracts outstanding and while we do not have a formal policy to settle all derivatives prior to the end of each quarter, our current practice is to do so. The effect of derivative instruments on our condensed consolidated statements of operations was insignificant for the ninethree months ended September 30, 2018March 31, 2019 and 2017.2018.
We are exposed to credit-related losses in the event of non-performance by counterparties to derivative financial instruments, but we do not expect any counterparties to fail to meet their obligations given their high credit ratings. In addition, we diversify this risk across several counterparties and actively monitor their ratings.
Foreign Currency Translation Risk
Fluctuations in foreign currencies impact the amount of total assets, liabilities, revenue, operating expenses and cash flows that we report for our foreign subsidiaries upon the translation of these amounts into U.S. dollars. If there is a change in foreign currency exchange rates, the amounts of assets, liabilities, revenue, operating expenses and cash flows that we report in U.S. dollars for foreign subsidiaries that transact in international currencies may be higher or lower to what we would have reported using a constant currency rate. To the extent the U.S. dollar strengthens against foreign currencies, the translation of these foreign currency denominated transactions results in reduced assets, liabilities, revenue, operating expenses and cash flows for our international operations. Similarly, our assets, liabilities, revenue, operating expenses and cash flows will increase for our international operations if the U.S. dollar weakens against foreign currencies. The conversion of the foreign subsidiaries’ financial statements into U.S.

dollars will also lead to remeasurement gains and losses recorded in income, or translation gains or losses that are recorded as a component of accumulated other comprehensive income (loss).

Item 4: Controls and Procedures
Evaluation of Disclosure Controls and Procedures
Our management, with the participation of our Chief Executive Officer and our Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as of September 30, 2018March 31, 2019. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms.
Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on the evaluation of our disclosure controls and procedures as of September 30, 2018March 31, 2019, our Chief Executive Officer and Chief Financial Officer concluded that, as of such date, our disclosure controls and procedures were effective at a reasonable assurance level.
Changes in Internal Control over Financial Reporting
There were no changes in our internal control over financial reporting that occurred during the quarter ended September 30, 2018March 31, 2019 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II: OTHER INFORMATION
Item 1. Legal Proceedings
From time to time, we have been and may be involved in various legal proceedings and claims arising in our ordinary course of business. At this time, neither we nor any of our subsidiaries is a party to, and none of our respective property is the subject of, any material legal proceeding. However, the outcome of legal proceedings and claims brought against us are subject to significant uncertainty. Therefore, if one or more of these legal matters were resolved against us in the same reporting period for amounts in excess of management’s expectations, our consolidated financial statements for a particular period could be materially adversely affected.
Item 1A. Risk Factors
For a discussion of our potential risks and uncertainties, see the information under the heading "Risk Factors"“Risk Factors” in our final prospectus dated October 18, 2018 and filed withAnnual Report on Form 10-K for the SEC on October 22, 2018 pursuant to Rule 424(b) of the Securities Act of 1933, as amended.year ended December 31, 2018. There have been no material changes from the risk factors disclosed in our final prospectus.therein.
Item 2. Unregistered Sales of Equity Securities and Use of Proceeds
On October 18, 2018, the Registration Statement on Form S-1 (File No.  333-227479) (the “Registration Statement”) relating to our initial public offering was declared effective by the SEC. Pursuant to the Registration Statement, we registered an aggregate of 25,000,000 shares of our common stock, all of which were sold by us at a price to the public of $15.00 per share. Goldman Sachs & Co. LLC, J.P. Morgan Securities LLC and Morgan Stanley & Co. LLC acted as the representatives of the underwriters in our initial public offering. We received approximately $353.0 million in net proceeds after deducting underwriting discounts and commissions of $17.8 million and estimated offering-related expenses of approximately $4.2 million. No payments of the net proceeds were made to our directors or officers or their associates, holders of 10% or more of any class of our equity securities or any affiliates. 
We used a portion of the net proceeds from the offering to repay $315.0 million in borrowings outstanding under our Second Lien Term Loan and a related voluntary prepayment fee of approximately $14.2 million concurrently with the closing of our initial public offering in October 2018. All of the remaining net proceeds are held in cash and have not been deployed. We intend to apply the remaining net proceeds to monthly interest payments under our First Lien Credit Agreement.
