income statement . items selected for fair-value accounting in accordance with sfas 155 and sfas 156 certain hybrid financial instruments the company has elected to apply fair-value accounting under sfas 155 for certain hybrid financial assets and liabilities whose performance is linked to risks other than interest rate , foreign exchange or inflation ( e.g. , equity , credit or commodity risks ) . in addition , the company has elected fair-value accounting under sfas 155 for residual interests retained from securitizing certain financial assets . the company has elected fair-value accounting for these instruments because these exposures are considered to be trading-related positions and , therefore , are managed on a fair-value basis . in addition , the accounting for these instruments is simplified under a fair-value approach as it eliminates the complicated operational requirements of bifurcating the embedded derivatives from the host contracts and accounting for each separately . the hybrid financial instruments are classified as trading account assets , loans , deposits , trading account liabilities ( for prepaid derivatives ) , short-term borrowings or long-term debt on the company 2019s consolidated balance sheet according to their legal form , while residual interests in certain securitizations are classified as trading account assets . for hybrid financial instruments for which fair-value accounting has been elected under sfas 155 and that are classified as long-term debt , the aggregate unpaid principal exceeds the aggregate fair value by $ 1.9 billion as of december 31 , 2008 , while the aggregate fair value exceeds the aggregate unpaid principal balance by $ 460 million as of december 31 , 2007 . the difference for those instruments classified as loans is immaterial . changes in fair value for hybrid financial instruments , which in most cases includes a component for accrued interest , are recorded in principal transactions in the company 2019s consolidated statement of income . interest accruals for certain hybrid instruments classified as trading assets are recorded separately from the change in fair value as interest revenue in the company 2019s consolidated statement of income . mortgage servicing rights the company accounts for mortgage servicing rights ( msrs ) at fair value in accordance with sfas 156 . 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 on page 175 for further discussions regarding the accounting and reporting of msrs . these msrs , which totaled $ 5.7 billion and $ 8.4 billion as of december 31 , 2008 and december 31 , 2007 , respectively , are classified as mortgage servicing rights on citigroup 2019s consolidated balance sheet . changes in fair value of msrs are recorded in commissions and fees in the company 2019s consolidated statement of income. .
