Use of Estimates

3. USE OF ESTIMATES

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Such estimates include, but are not limited to, the allowance for doubtful accounts, impairment of long-lived assets and goodwill, contingencies and litigation, the recognition of revenues and profits based on the proportional performance method and potential tax liabilities. Actual results could differ from those estimates and assumptions used in the preparation of the accompanying financial statements.
