Organization, Consolidation and Presentation of Financial Statements [Abstract]
Principles of Consolidation and Other Matters	Principles of Consolidation and Other Matters The consolidated financial statements included herein have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been omitted pursuant to such rules and regulations for interim filings, although the Company believes that the information and disclosures presented are adequate to make such information and disclosures not misleading. These consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012 (the “2012 10-K”) and the amended Items 7 and 8 of the Annual Report filed May 10, 2013. The financial information contained herein reflects all adjustments consisting only of normal recurring adjustments which are, in the opinion of management, necessary for a fair presentation of the Company’s results of operations for the three- and nine- month periods ended September 30, 2013 and 2012. Cash and Cash Equivalents Cash and cash equivalents primarily consist of certificates of deposit and time deposits, with original maturities of three months or less, and money market funds. The estimated fair value of the Company's cash and cash equivalents approximates their carrying value. The Company is required to maintain operating funds of approximately $250 million related to regulatory requirements outside the U.S. or as collateral under captive insurance arrangements. Investment Income The caption “Investment income” in the consolidated statements of income comprises realized and unrealized gains and losses from investments recognized in current earnings. It includes, when applicable, other than temporary declines in the value of debt and available for sale securities and the change in value of the Company’s holdings in certain private equity funds, including equity method gains (losses) on its investment in the Trident funds. The Company’s investments may include direct investments in insurance or consulting companies and investments in private equity funds. The Company recorded (losses) gains on its investment in Trident II of $0 million and $(1) million for the three months ended September 30, 2013 and 2012, respectively, and $20 million and $23 million for the nine months ended September 30, 2013 and 2012, respectively, including $15 million of deferred performance fees recognized in the first quarter of 2013. Trident II has now harvested substantially all its portfolio investments and there are no remaining capital commitments for this fund. The Company has recognized substantially all of the performance fees related to its general partnership interest in Trident II. Investment income for the three- and nine- months ended September 30, 2013 includes performance fees of $13 million and $34 million, respectively, which had been deferred, that are no longer subject to claw-back from Trident III. At September 30, 2013, the Company has deferred performance fees of approximately $43 million related to Trident III. Recognition of these deferred performance fees will only occur as investments are harvested and the performance fees are no longer subject to claw-back. Timing of this is unknown and is not controlled by the Company. Income Taxes The Company's effective tax rate in the third quarter of 2013 was 32.1%. This rate reflects non-U.S. earnings subject to tax at rates below the U.S. statutory rate, including the effect of repatriation and the impact of tax rate changes on the Company's deferred tax assets and liabilities. The Company's effective tax rate in the third quarter of 2012 was 26.8%. As discussed above, this rate reflects non-U.S. earnings subject to tax at rates below the U.S. statutory rate, including the effect of repatriation. In addition, it reflects several discrete tax benefits, including the benefit from recording previously unrecognized tax benefits as a result of expiring statutes of limitations for U.S. federal tax years 2006 and 2008, and a favorable permanent difference related to a tax-free adjustment to the estimated liability for contingent consideration. Partially offsetting these benefits in the quarter were charges to increase unrecognized tax benefits for certain operations in Asia and U.S. tax costs related to actions taken during the quarter to reduce positions in the Euro currency held by certain of the Company's non-U.S. operations. The effective tax rate for the first nine months of 2013 was 30.1% compared with 29.2% for the first nine months of 2012. The rate in both periods reflects non-U.S. earnings subject to tax at rates below the U.S. statutory rate, including the effect of repatriation, and the impact of discrete tax matters such as the resolution of tax examinations. The Company is routinely examined by tax authorities in the jurisdictions in which it has significant operations. The Company regularly considers the likelihood of assessments in each of the taxing jurisdictions resulting from examinations. When evaluating the potential imposition of penalties, the Company considers a number of relevant factors under penalty statutes, including appropriate disclosure of the tax return position, the existence of legal authority supporting the Company's position, and reliance on the opinion of professional tax advisors. The Company reports a liability for unrecognized tax benefits resulting from uncertain tax positions taken or expected to be taken in tax returns. The Company's gross unrecognized tax benefits increased from $117 million at December 31, 2012 to $133 million at September 30, 2013. It is reasonably possible that the total amount of unrecognized tax benefits will decrease between zero and approximately $20 million within the next twelve months due to settlement of audits and expiration of statutes of limitation.
