use of estimates the preparation of the accompanying consolidated financial statements in conformity with u.s . gaap requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities , disclosures of contingent assets and liabilities at the date of the financial statements , and the reported amounts of reserves and expenses . these estimates and assumptions are based on management's best estimates and judgments . management evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors , including the current economic environment . management believes its estimates to be reasonable given the current facts available . aon adjusts such estimates and assumptions when facts and circumstances dictate . illiquid credit markets , volatile equity markets , and foreign currency exchange rate movements increase the uncertainty inherent in such estimates and assumptions . as future events and their effects cannot be determined , among other factors , with precision , actual results could differ significantly from these estimates . changes in estimates resulting from continuing changes in the economic environment would , if applicable , be reflected in the financial statements in future periods. .
