[1] Non-recurring changes in fair value for loans held for investment were calculated based upon the fair value of the underlying collateral. The fair value of the collateral was determined using internal expected recovery models. The non-recurring change in fair value for mortgage loans held for sale is based upon a valuation model incorporating market observable inputs.
[2] Losses recorded were determined primarily using discounted cash flow models.
[3] Losses were determined using discounted cash flow models and primarily represented the write-off of the carrying value of certain premises and software that were abandoned during 2012 in association with the Morgan Stanley Wealth Management integration.
[4] Losses were determined primarily using discounted cash flow models or a valuation technique incorporating an observable market index.
[5] Losses primarily related to investment management contracts, including contracts associated with FrontPoint, and were determined primarily using discounted cash flow models.
[6] The amount of the Company’s goodwill before accumulated impairments of $700 million, which included $673 million related to the Institutional Securities business segment and $27 million related to the Asset Management business segment, was $7,350 million and $7,386 million at December 31, 2012 and December 31, 2011, respectively.
[7] Loss relates to FrontPoint, determined primarily using discounted cash flow models (see Notes 19 and 24 for further information on FrontPoint).
[8] Includes all loans measured at fair value on a non-recurring basis.
[9] Losses are recorded within Other expenses in the consolidated statements of income except for fair value adjustments related to Loans and losses related to Other investments, which are included in Other revenues.
[10] Losses related to Loans, impairments related to Other investments and losses related to Goodwill and certain Intangibles associated with the disposition of FrontPoint Partners LLC (“FrontPoint”) are included in Other revenues in the consolidated statements of income (see Notes 19 and 24 for further information on FrontPoint).
