Reconciliation of Non-GAAP Financial Measures to GAAP Measures

To supplement the consolidated financial statements presented in accordance with GAAP, this press release includes the following measures defined by the Securities and Exchange Commission as non-GAAP financial measures:

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, the financial statements prepared in accordance with GAAP and the reconciliations of Genpact’s GAAP financial statements to such non-GAAP financial measures should be carefully evaluated.

Prior to July 2012, Genpact’s management used financial statements that excluded significant acquisition-related expenses, amortization of related acquired intangibles, and amortization of acquired intangibles at the Company’s formation in 2004 for its internal management reporting, budgeting and decision making purposes, including comparing Genpact’s operating results to that of its competitors. However, considering Genpact’s frequent acquisitions of varying scale and size, and the difficulty in predicting expenses relating to acquisitions and amortization of acquired intangibles thereof, since July 2012 Genpact’s management uses financial statements that exclude all acquisition-related expenses and amortization of acquired intangibles for its internal management reporting, budgeting and decision-making purposes, including comparing Genpact’s operating results to that of its competitors. Acquisition-related expenses are excluded in the period in which an acquisition is consummated.

Additionally, Genpact’s management uses financial statements that exclude stock-based compensation expense. Because of varying available valuation methodologies, subjective assumptions and the variety of award types that companies can use when adopting ASC 718 “Compensation-Stock Compensation,” Genpact’s management believes that providing non-GAAP financial measures that exclude such expenses allows investors to make additional comparisons between Genpact’s operating results and those of other companies. Genpact also believes that it is unreasonably difficult to provide its financial outlook in accordance with GAAP for a number of reasons, including, without limitation, its inability to predict its stock-based compensation expense under ASC 718, the amortization of intangibles associated with further acquisitions and acquisition-related expenses. Accordingly, Genpact believes that the presentation of adjusted income from operations and adjusted net income, when read in conjunction with the Company’s reported results, can provide useful supplemental information to investors and management regarding financial and business trends relating to its financial condition and results of operations.

A limitation of using adjusted income from operations and adjusted net income versus income from operations and net income calculated in accordance with GAAP is that these non-GAAP financial measures exclude a recurring cost, namely stock-based compensation. Management compensates for this limitation by providing specific information on the GAAP amounts excluded from adjusted income from operations and adjusted net income.

The following tables show the reconciliation of these adjusted financial measures from GAAP for the three and six months ended June 30, 2014 and 2015:
