the changes in fair values of these mortgage loans are reported in other revenue in the company 2019s consolidated statement of income .
the changes in fair value during the years ended december 31 , 2009 and 2008 due to instrument-specific credit risk resulted in a $ 10 million loss and $ 32 million loss , respectively .
related interest income continues to be measured based on the contractual interest rates and reported as such in the consolidated statement of income .
mortgage servicing rights the company accounts for mortgage servicing rights ( msrs ) at fair value .
fair value for msrs is determined using an option-adjusted spread valuation approach .
this approach consists of projecting servicing cash flows under multiple interest-rate scenarios and discounting these cash flows using risk-adjusted rates .
the model assumptions used in the valuation of msrs include mortgage prepayment speeds and discount rates .
the fair value of msrs is primarily affected by changes in prepayments that result from shifts in mortgage interest rates .
in managing this risk , the company hedges a significant portion of the values of its msrs through the use of interest-rate derivative contracts , forward-purchase commitments of mortgage-backed securities , and purchased securities classified as trading .
see note 23 to the consolidated financial statements for further discussions regarding the accounting and reporting of msrs .
these msrs , which totaled $ 6.5 billion and $ 5.7 billion as of december 31 , 2009 and 2008 , respectively , are classified as mortgage servicing rights on citigroup 2019s consolidated balance sheet .
