USE OF NON-GAAP FINANCIAL MEASURES

In evaluating the business, the Company considers and uses non-GAAPoperating 
income and non-GAAP net income, each a non-GAAP financial measure, in 
reviewing and assessing the Company's operatingperformance. The presentation 
of these non-GAAP financial measures is not intended to be considered in 
isolation or as a substitute forthe financial information prepared and 
presented in accordance with U.S. GAAP. The Company presents these non-GAAP 
financial measuresbecause they are used by the Company's management to 
evaluate operating performance and formulate business plans. The Company 
believesthat the non-GAAP financial measures help identify underlying trends 
in the Company's business, provide further information aboutthe Company's 
results of operations and enhance the overall understanding of the Company's 
past performance and future prospects.

The non-GAAP financial measures are not defined under U.S. GAAP andare not 
presented in accordance with U.S. GAAP. The non-GAAP financial measures have 
limitations as analytical tools. The Company'snon-GAAP financial measures do 
not reflect all items of income and expense that affect the Company's 
operations and do not representthe residual cash flow available for 
discretionary expenditures. Furthermore, these non-GAAP measures may differ 
from the non-GAAP informationused by other companies, including peer 
companies, and therefore their comparability may be limited. The Company 
compensates for theselimitations by reconciling the non-GAAP financial 
measures to the nearest U.S. GAAP performance measure, all of which should be 
consideredwhen evaluating the Company's performance. The Company encourages 
investors and others to review the Company's financial informationin its 
entirety and not rely on a single financial measure.

The Company defines non-GAAP operating income as operating income 
excludingshare-based compensation expenses, non-GAAP net income as net income 
excluding recurring item of share-based compensation expenses andnon-recurring 
item of provision for equity litigants, and non-GAAP net income attributable 
to the Company's ordinary shareholdersas net income attributable to the 
Company's ordinary shareholders excluding recurring item of share-based 
compensation expensesand non-recurring item of provision for equity litigants.
