Non-GAAP Financial Measures

To supplement HiSoft’s consolidated financial results presented in accordance with GAAP, HiSoft uses the following measures defined as non-GAAP financial measures by the SEC: Non-GAAP gross margin, non-GAAP operating income, non-GAAP net income and non-GAAP diluted net income per ADS and related margins which exclude share-based compensation expense, amortization of acquired intangible assets and change in fair value of contingent consideration payable for business acquisition and acquisition expenses. The presentation of these non-GAAP financial measures is not intended to be considered in isolation or as a substitute for the financial information prepared and presented in accordance with GAAP.

A limitation of using non-GAAP gross margin, non-GAAP operating income, non-GAAP net income and non-GAAP diluted net

income per ADS and related margins is that these non-GAAP measures exclude the share-based compensation charges, amortization of acquired intangible assets, change in fair value of contingent consideration payable for business acquisition that have been and will continue to be for the foreseeable future a significant recurring expense in the business and acquisition expenses. The presentation of these measures should not be considered a substitute for or superior to GAAP results or as being comparable to results reported of forecasted by other companies. Management compensates for these limitations by providing specific information regarding the GAAP amounts excluded from each non-GAAP measure.   For more information on these non-GAAP financial measures, please see the table captioned “Reconciliations of Non-GAAP Financial Measures to Comparable GAAP Measures” set forth in HiSoft’s second quarter 2012 earnings announcement dated August 10, 2012.
