Servicing Activities

Mortgage Servicing Rights

The following table summarizes past activity related to mortgage servicing rights (MSRs), which were carried at fair value. Management estimated fair value using our transaction data and other market data or, in periods when there were limited MSRs market transactions that were directly observable, internally developed discounted cash flow models (an income approach) were used to estimate the fair value. These internal valuation models estimated net cash flows based on internal operating assumptions that we believed would be used by market participants in orderly transactions combined with market-based assumptions for loan prepayment rates, interest rates, and discount rates that we believed approximate yields required by investors in this asset.



Three months ended March 31, ($ in millions)	2014		2013
Estimated fair value at January 1,	$	—	$	952
Additions	—		54
Changes in fair value
Due to changes in valuation inputs or assumptions used in the valuation model	—		(28		)
Other changes in fair value	—		(61		)
Estimated fair value at March 31,	$	—	$	917

Changes in fair value due to changes in valuation inputs or assumptions used in the valuation model included all changes due to a revaluation by a model or by a benchmarking exercise. Other changes in fair value primarily included the accretion of the present value of the discount related to forecasted cash flows and the economic runoff of the portfolio.

Risk Mitigation Activities

The primary risk of servicing rights is interest rate risk and the resulting impact on prepayments. A significant decline in interest rates could lead to higher-than-expected prepayments that could reduce the value of the MSRs. We previously economically hedged the impact of these risks with both derivative and nonderivative financial instruments. Refer to Note 19 for additional information regarding the derivative financial instruments used to economically hedge MSRs.

Automobile Finance Servicing Activities

We service consumer automobile contracts. Historically, we have sold a portion of our consumer automobile contracts. With respect to contracts we sell, we retain the right to service and earn a servicing fee for our servicing function. Typically, we conclude that the fee we are paid for servicing consumer automobile finance receivables represents adequate compensation, and consequently, we do not recognize a servicing asset or liability. We recognized automobile servicing fees of $9 million and $19 million during the three months ended March 31, 2014 and 2013, respectively.
