About Non-GAAP Financial Measures

To supplement Ctrip’s unaudited condensed consolidated financial statements presented in accordance with United States Generally Accepted Accounting Principles (“GAAP”), Ctrip uses non-GAAP financial information related to product development expenses, sales and marketing expenses, general and administrative expenses, income from operations, operating margin, net income, and diluted earnings per ordinary share and per ADS, each of which is adjusted from the most comparable GAAP result to exclude the share-based compensation charges recorded under ASC 718, “Compensation-Stock Compensation” for 2013 and 2012. Ctrip’s management believes the non-GAAP financial measures facilitate better understanding of operating results from quarter to quarter and provide management with a better capability to plan and forecast future periods.

Non-GAAP information is not prepared in accordance with GAAP and may be different from non-GAAP methods of accounting and reporting used by other companies. The presentation of this additional information should not be considered a substitute for GAAP results. A limitation of using non-GAAP financial measures is that non-GAAP measures exclude share-based compensation charges that have been and will continue to be significant recurring expenses in Ctrip’s business for the foreseeable future.

Reconciliations of Ctrip’s non-GAAP financial data to the most comparable GAAP data included in the consolidated statement of operations are included at the end of this press release.
