In March of 2013, the Bancorp recognized an immaterial loss on the securitization and sale of certain automobile loans with a carrying amount of approximately $509 million. The Bancorp utilized a securitization trust to facilitate the securitization process. The trust issued asset-backed securities in the form of notes and equity certificates, with varying levels of credit subordination and payment priority. The Bancorp does not hold any of the notes or equity certificates issued by the trust, and the investors in these securities have no credit recourse to the Bancorp's assets for failure of debtors to pay when due. As part of the sale, the Bancorp obtained servicing responsibilities and recognized a servicing asset with an initial fair value of $6 million.

The Bancorp sold fixed and adjustable rate residential mortgage loans during the three months ended March 31, 2014 and 2013. In those sales, the Bancorp obtained servicing responsibilities and the investors have no recourse to the Bancorp's other assets for failure of debtors to pay when due. The Bancorp receives annual servicing fees based on a percentage of the outstanding balance. The Bancorp identifies classes of servicing assets based on financial asset type and interest rates.

The Bancorp's projections of amortization expense shown below are based on existing asset balances as of March 31, 2014. Future amortization expense may vary from these projections. Estimated amortization expense for the remainder of 2014 through 2018 is as follows:

Temporary impairment or impairment recovery, affected through a change in the MSR valuation allowance, is captured as a component of mortgage banking net revenue in the Condensed Consolidated Statements of Income. The Bancorp maintains a non-qualifying hedging strategy to manage a portion of the risk associated with changes in the value of the MSR portfolio. This strategy includes the purchase of free-standing derivatives and various available-for-sale securities. The interest income, mark-to-market adjustments and gain or loss from sale activities associated with these portfolios are expected to economically hedge a portion of the change in value of the MSR portfolio caused by fluctuating discount rates, earnings rates and prepayment speeds. The fair value of the servicing asset is based on the present value of expected future cash flows.

The following table displays the beginning and ending fair value of the servicing assets for the three months ended March 31:

($ in millions)		2014	2013
Fixed rate residential mortgage loans:
Beginning balance	$	929	664
Ending balance		935	731
Adjustable rate residential mortgage loans:

As of March 31, 2014 and 2013, the key economic assumptions used in measuring the interests in residential mortgage loans that continued to be held by the Bancorp at the date of sale or securitization resulting from transactions completed during the three months ended were as follows:

		March 31, 2014						March 31, 2013
	Rate	Weighted-Average Life (in years)	Prepayment Speed (annual)		Discount Rate (annual)		Weighted-Average Default rate	Weighted-Average Life (in years)	Prepayment Speed (annual)		Discount Rate (annual)		Weighted-Average Default rate
Residential mortgage loans:
Servicing assets	Fixed	6.7	10.8	%	10.0	%	N/A	7.3	8.8	%	10.0	%	N/A
Servicing assets	Adjustable	3.7	22.5		11.7		N/A	3.5	23.4		11.4		N/A

Based on historical credit experience, expected credit losses for residential mortgage loan servicing assets have been deemed immaterial, as the Bancorp sold the majority of the underlying loans without recourse. At March 31, 2014 and December 31, 2013, the Bancorp serviced $68.9 billion and $69.2 billion, respectively, of residential mortgage loans for other investors. The value of MSRs that continue to be held by the Bancorp is subject to credit, prepayment and interest rate risks on the sold financial assets.

At March 31, 2014, the sensitivity of the current fair value of residual cash flows to immediate 10%, 20% and 50% adverse changes in prepayment speed assumptions and immediate 10% and 20% adverse changes in other assumptions are as follows:

					Prepayment						Residual Servicing
					Speed Assumption						Cash Flows
			Fair	Weighted-Average Life (in				Impact of Adverse Change on Fair Value			Discount			Impact of Adverse Change on Fair Value
($ in millions)^(a)	Rate		Value	years)	Rate			10%	20%	50%	Rate			10%	20%
Residential mortgage loans:
Servicing assets	Fixed	$	935	6.6	10.6	%	$	(37)	(72)	(163)	9.9	%	$	(36)	(69)
Servicing assets	Adjustable		37	3.1	26.1			(2)	(3)	(7)	11.8			(1)	(2)

These sensitivities are hypothetical and should be used with caution. As the figures indicate, changes in fair value based on these variations in the assumptions typically cannot be extrapolated because the relationship of the change in assumption to the change in fair value may not be linear. The Bancorp believes variations of these levels are reasonably possible; however, there is the potential that adverse changes in key assumptions could be even greater. Also, in the previous table, the effect of a variation in a particular assumption on the fair value of the interests that continue to be held by the Bancorp is calculated without changing any other assumption; in reality, changes in one factor may result in changes in another (for example, increases in market interest rates may result in lower prepayments), which might magnify or counteract these sensitivities.
