As disclosed in the Quarterly Report on Form 10-Q for the quarter ended June 30, 2008 filed by MMC on August 8, 2008, performance measurements for segment revenue and segment operating income used by MMC’s chief operating decision maker to evaluate performance and for the allocation of resources were changed, so that investment gains and losses derived from investments strategically linked to MMC’s operating companies are no longer included. The presentation of segment revenue and segment operating income was conformed accordingly. The amounts are now reflected as “Investment income (loss),” which is presented outside of MMC’s operating income. In addition, the related cash flows received from or paid for certain investments have been similarly changed in the consolidated statements of cash flows. In order to reflect this change, MMC also filed a Current Report on Form 8-K dated September 5, 2008 amending the following sections of MMC's Annual Report on Form 10-K for the year ended December 31, 2007 (the "2007 10-K"): selected financial data (Item 6 of the 2007 10-K); management's discussion and analysis of financial condition and results of operations (Item 7 of the 2007 10-K); and financial statements and supplementary data (Item 8 of the 2007 10-K).
