* As required by EITF 04-08 the calculation of diluted earnings per share includes the addition to Net Income of interest expense related to the Company’s contingently convertible securities, net of tax, of $3.0, $6.7, $17.6 and $23.8 for the years ended December 31, 2004, December 31, 2005, December 31, 2006 and December 31, 2007, respectively.

(1) Cash Net Income is defined as Net Income plus amortization and deferred taxes related to intangible assets plus Affiliate depreciation. This supplemental non-GAAP performance measure is provided in addition to, but not as a substitute for, Net Income. The Company considers Cash Net Income an important measure of its financial performance, as management believes it best represents operating performance before non-cash expenses relating to the acquisition of interests in its affiliated investment management firms. Since acquired assets do not generally depreciate or require replacement, and since they generate deferred tax expenses that are unlikely to reverse, the Company adds back these non-cash expenses. Cash Net Income is used by the Company’s management and Board of Directors as a principal performance benchmark.

The Company adds back amortization attributable to acquired client relationships because this expense does not correspond to the changes in value of these assets, which do not diminish predictably over time. The Company adds back the portion of deferred taxes generally attributable to intangible assets (including goodwill) that it no longer amortizes but which continues to generate tax deductions. These deferred tax expense accruals would be used in the event of a future sale of an Affiliate or an impairment charge, which the Company considers unlikely. The Company adds back the portion of consolidated depreciation expense incurred by Affiliates because under its Affiliate operating agreements, the Company is generally not required to replenish these depreciating assets.

(2) EBITDA is defined as earnings before interest expense, income taxes, depreciation and amortization. This supplemental non-GAAP liquidity measure is provided in addition to, but not as a substitute for, cash flow from operations. As a measure of liquidity, the Company believes EBITDA is useful as an indicator of its ability to service debt, make new investments and meet working capital requirements. EBITDA, as calculated by the Company, may not be consistent with computations of EBITDA by other companies.

(3) Cash earnings per share represents Cash Net Income divided by the adjusted diluted average shares outstanding. In this calculation, the potential share issuance in connection with the Company’s contingently convertible securities is measured using a “treasury stock” method. Under this method, only the net number of shares of common stock equal to the value of the contingently convertible securities and the junior convertible trust preferred securities in excess of par, if any, are deemed to be outstanding. The Company believes the inclusion of net shares under a treasury stock method best reflects the benefit of the increase in available capital resources (which could be used to repurchase shares of common stock) that occurs when these securities are converted and the Company is relieved of its debt obligation. This method does not take into account any increase or decrease in the Company’s cost of capital in an assumed conversion.
