APPENDIX: About Non-GAAP Financial Measures

To supplement our financial results presented in accordance with GAAP, this earnings supplement includes references to the following measures defined by the Securities and Exchange Commission as non-GAAP financial measures: Adjusted Income From Operations, Adjusted Operating Margin, Adjusted Diluted EPS, free cash flow, Adjusted effective tax rate, and constant currency revenue growth. These non-GAAP financial measures are not based on any comprehensive set of accounting rules or principles and should not be considered a substitute for, or superior to, financial measures calculated in accordance with GAAP, and may be different from non-GAAP financial measures used by other companies. In addition, these non-GAAP financial measures should be read in conjunction with our financial statements prepared in accordance with GAAP. The reconciliations of our non-GAAP financial measures to the corresponding GAAP measures should be carefully evaluated. Our non-GAAP financial measures, Adjusted Operating Margin, Adjusted Income From Operations and Adjusted Diluted EPS exclude unusual items. Additionally, Adjusted Diluted EPS excludes net non-operating foreign currency exchange gains or losses and the tax impact of all the applicable adjustments. The income tax impact of each item is calculated by applying the statutory rate and local tax regulations in the jurisdiction in which the item was incurred. Free cash flow is defined as cash flows from operating activities net of purchases of property and equipment. Constant currency revenue growth is defined as revenues for a given period restated at the comparative period’s foreign currency exchange rates measured against the comparative period's reported revenues. Adjusted effective tax rate reflects a tax rate commensurate with our non-GAAP Adjusted EPS. We believe providing investors with an operating view consistent with how we manage the Company provides enhanced transparency into our operating results. For our internal management reporting and budgeting purposes, we use various GAAP and non-GAAP financial measures for financial and operational decision- making, to evaluate period-to-period comparisons, to determine portions of the compensation for our executive officers and for making comparisons of our operating results to those of our competitors. Therefore, it is our belief that the use of non-GAAP financial measures excluding certain costs provides a meaningful supplemental measure for investors to evaluate our financial performance. Accordingly, we believe that the presentation of our non-GAAP measures, when read in conjunction with our reported GAAP results, can provide useful supplemental information to our management and investors regarding financial and business trends relating to our financial condition and results of operations. A limitation of using non-GAAP financial measures versus financial measures calculated in accordance with GAAP is that non-GAAP financial measures do not reflect all of the amounts associated with our operating results as determined in accordance with GAAP and may exclude costs that are recurring such as our net non-operating foreign currency exchange gains or losses. In addition, other companies may calculate non-GAAP financial measures differently than us, thereby limiting the usefulness of these non-GAAP financial measures as a comparative tool. We compensate for these limitations by providing specific information regarding the GAAP amounts excluded from our non-GAAP financial measures to allow investors to evaluate such non-GAAP financial measures.

Reconciliations of Non-GAAP Financial Measures Notes: (a) During 2019 and 2020, we incurred realignment charges that consisted of employee separation costs, employee retention costs and professional fees. The total costs related to the realignment are reported in "Restructuring charges" in our consolidated statements of operations. (b) During 2019 and 2020, we incurred restructuring charges as part of our 2020 Fit for Growth Plan that included employee separation costs, employee retention costs, facility exit costs and other charges. The total costs related to the 2020 Fit for Growth Plan are reported in "Restructuring charges" in our consolidated statements of operations. (c) During 2020, we incurred costs in response to the COVID-19 pandemic, including a one-time bonus to our employees at the designation of associate and below in both India and the Philippines, certain costs to enable our employees to work remotely and costs to provide medical staff and extra cleaning services for our facilities. Most of the costs related to the pandemic are reported in "Cost of revenues" in our consolidated statement of operations. (d) During the first quarter of 2019, a ruling of the Supreme Court of India in interpreting certain statutory defined contribution obligations of employees and employers (the "India Defined Contribution Obligation") altered historical understandings of such obligations, extending them to cover additional portions of the employee's income. As a result, the ongoing contributions of our affected employees and the Company have increased. In the first quarter of 2019, we accrued $117 million with respect to prior periods, assuming retroactive application of the Supreme Court's ruling. There is significant uncertainty as to how the liability should be calculated as it is impacted by multiple variables, including the period of assessment, the application with respect to certain current and former employees and whether interest and penalties may be assessed. Since the ruling, a variety of trade associations and industry groups have advocated to the Indian government, highlighting the harm to the information technology sector, other industries and job growth in India that would result from a retroactive application of the ruling. It is possible that the Indian government will review the matter and there is a substantial question as to whether the Indian government will apply the Supreme Court's ruling on a retroactive basis. As such, the ultimate amount of our obligation may be materially different from the amount accrued. The incremental accrual related to the India Defined Contribution Obligation is reported in "Selling, general, and administrative expenses" in our consolidated statement of operations. (e) Non-operating foreign currency exchange gains and losses, inclusive of gains and losses related to foreign exchange forward contracts not designated as hedging instruments for accounting purposes, are reported in "Foreign currency exchange gains (losses), net" in our consolidated statements of operations. Non-operating foreign currency exchange gains and losses are subject to high variability and low visibility and therefore cannot be provided on a forward-looking basis without unreasonable efforts. 16

The recorded income tax expense reflects the India withholding tax on unrepatriated Indian earnings, which were $5.2 billion as of December 31, 2019, net of applicable U.S. foreign tax credits. (h) During the fourth quarter of 2019, we determined that the carrying value of one of our equity method investments exceeded its fair value and therefore recorded an impairment charge of $57 million within the caption "Income (loss) from equity method investments" in our consolidated statement of operations. (i) During the fourth quarter of 2019, the Government of India enacted a new tax regime ("India Tax Law") effective retroactively to April, 2019 that enables domestic companies to elect to be taxed at a lower income tax rate of 25.17%, as compared to the current income tax rate of 34.94%. Once a company elects into the lower income tax rate, a company may not benefit from any tax holidays associated with Special Economic Zones and certain other tax incentives, including Minimum Alternative Tax credit carryforwards, and may not reverse its election. As a result of the enactment of the India Tax Law, we recorded a one-time net income tax expense of $21 million due to the revaluation to the lower income tax rate of our India net deferred income tax assets that were expected to reverse after we elected into the new tax regime.
