Significant Judgments, Estimates and Assumptions [Abstract]
Significant Judgments, Estimates and Assumptions	3. Significant judgments, estimates and assumptions The preparation of financial statements in conformity with US GAAP requires management to make judgments, estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Future differences arising between actual results and the judgments, estimates and assumptions made by the Company at the reporting date, or future changes to estimates and assumptions, could necessitate adjustments to the underlying reported amounts of assets, liabilities, revenues and expenses in future reporting periods. Judgments, estimates and underlying assumptions are evaluated on an ongoing basis by management, and are based on historical experience and other factors including expectations of future events that are believed to be reasonable under the circumstances. Existing circumstances and assumptions about future developments, however, may change due to market changes or circumstance and such changes are reflected in the assumptions when they occur. Significant estimates include the estimated useful lives of long-lived assets, as well as valuation of goodwill, underwritten commission contracts, contingently redeemable non-controlling interest and share-based compensation.

3. Significant judgments, estimates and assumptions

The preparation of financial statements in conformity with US GAAP requires management to make judgments, estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period.

Future differences arising between actual results and the judgments, estimates and assumptions made by the Company at the reporting date, or future changes to estimates and assumptions, could necessitate adjustments to the underlying reported amounts of assets, liabilities, revenues and expenses in future reporting periods.

Judgments, estimates and underlying assumptions are evaluated on an ongoing basis by management, and are based on historical experience and other factors including expectations of future events that are believed to be reasonable under the circumstances. Existing circumstances and assumptions about future developments, however, may change due to market changes or circumstance and such changes are reflected in the assumptions when they occur. Significant estimates include the estimated useful lives of long-lived assets, as well as valuation of goodwill, underwritten commission contracts, contingently redeemable non-controlling interest and share-based compensation.
