In reporting period-over-period results, we calculate the effects of foreign currency fluctuations and constant currency information by translating current period results using prior period average foreign currency exchange rates. Our definition of constant currency may differ from other companies reporting similarly named measures, and these constant currency performance measures should be viewed in addition to, and not as a substitute for, our operating performance measures calculated in accordance with GAAP.

• Our last twelve-month recurring revenues dollar-based net retention rate is calculated, using the average exchange rates for the prior period, as follows: the recurring revenues for the current period, including any growth or reductions from accounts with recurring revenues in the prior period (“existing accounts”), but excluding recurring revenues from any new accounts added during the current period, divided by the total recurring revenues from all accounts during the prior period. A period is defined as any trailing twelve months;
• Our last twelve-month account retention rate for any given twelve-month period is calculated using the average currency exchange rates for the prior period, as follows: the prior period recurring revenues from all accounts with recurring revenues in the current and prior period, divided by total recurring revenues from all accounts during the prior period; and
• Our ARR growth rate is the growth rate of our ARR, measured on a constant currency basis.

Use and Reconciliation of Non-GAAP Financial Measures

In addition to our results determined in accordance with GAAP, we have calculated Adjusted cost of subscriptions and licenses, Adjusted cost of services, Adjusted research and development, Adjusted selling and marketing, Adjusted general and administrative, Adjusted income from operations, Adjusted Net Income, and Adjusted EBITDA, each of which are nonâ�‘GAAP financial measures. We have provided tabular reconciliations of each of these nonâ�‘GAAP financial measures to such measure’s most directly comparable GAAP financial measure.

Management uses these non�GAAP financial measures to understand and compare operating results across accounting periods, for internal budgeting and forecasting purposes, and to evaluate financial performance. Our non�GAAP financial measures are presented as supplemental disclosure as we believe they provide useful information to investors and others in understanding and evaluating our results and prospects period-over-period without the impact of certain items that do not directly correlate to our operating performance and that may vary significantly from period to period for reasons unrelated to our operating performance, as well as to compare our financial results to those of other companies. Our definitions of these non�GAAP financial measures may differ from similarly titled measures presented by other companies and therefore comparability may be limited. In addition, other companies may not publish these or similar metrics. Thus, our non�GAAP financial measures should be considered in addition to, not as a substitute for, or in isolation from, the financial information prepared in accordance with GAAP, and should be read in conjunction with the financial statements included in our Quarterly Report on Form 10-Q to be filed with the United States Securities and Exchange Commission.

We calculate these non�GAAP financial measures as follows:

• Adjusted cost of subscriptions and licenses is determined by adding back to GAAP cost of subscriptions and licenses, amortization of purchased intangibles and developed technologies, stock-based compensation, acquisition expenses, and realignment expenses, for the respective periods;
• Adjusted cost of services is determined by adding back to GAAP cost of services, stock-based compensation, acquisition expenses, and realignment expenses, for the respective periods;
• Adjusted research and development is determined by adding back to GAAP research and development, stock-based compensation and acquisition expenses, for the respective periods;
• Adjusted selling and marketing is determined by adding back to GAAP selling and marketing, stock-based compensation, acquisition expenses, and realignment expenses, for the respective periods;
• Adjusted general and administrative is determined by adding back to GAAP general and administrative, stock-based compensation, acquisition expenses, and realignment expenses, for the respective periods;
• Adjusted income from operations is determined by adding back to GAAP operating income, amortization of purchased intangibles and developed technologies, stock-based compensation, expense (income) relating to deferred compensation plan liabilities, acquisition expenses, and realignment expenses, for the respective periods;
• Adjusted Net Income is defined as net income adjusted for the following: amortization of purchased intangibles and developed technologies, stock-based compensation, expense (income) relating to deferred compensation plan liabilities, acquisition expenses, realignment expenses, other non-operating (income) expense, net, the tax effect of the above adjustments to net income, and (income) loss from investment accounted for using the equity method, net of tax. The income tax effect of nonâ�‘GAAP adjustments was determined using the applicable rates in the taxing jurisdictions in which income or expense occurred, and represent both current and deferred income tax expense or benefit based on the nature of the nonâ�‘GAAP adjustments, including the tax effects of non-cash stock-based compensation expense; and
• Adjusted EBITDA is defined as net income adjusted for interest expense, net, provision (benefit) for income taxes, depreciation and amortization, stock-based compensation, expense (income) relating to deferred compensation plan liabilities, acquisition expenses, realignment expenses, other non-operating (income) expense, net, and (income) loss from investment accounted for using the equity method, net of tax.

We encourage investors and others to review our financial information in its entirety, not to rely on any single financial measure, and to view these non�GAAP financial measures in conjunction with the related GAAP financial measures. During the second quarter of 2022, the Company modified its definitions of Adjusted EBITDA and Adjusted Net Income to adjust for realignment expenses relating to our wind down of business in, and exit from, the Russian market. These realignment expenses are comprised of termination benefits for colleagues whose positions were eliminated and corresponding asset impairments. During the third quarter of 2021, the Company modified its definitions of Adjusted EBITDA and Adjusted Net Income to adjust for expense (income) relating to deferred compensation plan liabilities. Amounts for all periods herein reflect application of the aforementioned definition modifications.

During the fourth quarter of 2021, we early adopted Accounting Standards Update No. 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers, effective January 1, 2021 and retrospectively recasted interim prior period amounts presented in this press release.
