6. Loan sales and Securitizations

Residential Mortgage Loans

The following table summarizes activity relating to residential mortgage loans sold with servicing retained for the three-month and nine-month periods ended September 30, 2012 and 2011:

A MSR is established only when the servicing is contractually separated from the underlying mortgage loans by sale or securitization of the loans with servicing rights retained. At initial recognition, the MSR asset is established at its fair value using assumptions consistent with assumptions used to estimate the fair value of existing MSRs. At the time of initial capitalization, MSRs are recorded using either the fair value method or the amortization method. The election of the fair value method or amortization method is made at the time each servicing asset is established and is based upon Management's forward assumptions regarding interest rates. MSRs are included in accrued income and other assets. Any increase or decrease in the fair value of MSRs carried under the fair value method, as well as amortization or impairment of MSRs recorded using the amortization method, during the period is recorded as an increase or decrease in mortgage banking income, which is reflected in noninterest income in the Unaudited Condensed Consolidated Statements of Income.

The following tables summarize the changes in MSRs recorded using either the fair value method or the amortization method for the three-month and nine-month periods ended September 30, 2012 and 2011:

MSRs do not trade in an active, open market with readily observable prices. While sales of MSRs occur, the precise terms and conditions are typically not readily available. Therefore, the fair value of MSRs is estimated using a discounted future cash flow model. The model considers portfolio characteristics, contractually specified servicing fees and assumptions related to prepayments, delinquency rates, late charges, other ancillary revenues, costs to service, and other economic factors. Changes in the assumptions used may have a significant impact on the valuation of MSRs.

MSR values are very sensitive to movements in interest rates as expected future net servicing income depends on the projected outstanding principal balances of the underlying loans, which can be greatly impacted by the level of prepayments. Huntington hedges the value of certain MSRs against changes in value attributable to changes in interest rates using a combination of derivative instruments and trading securities.

For MSRs under the fair value method, a summary of key assumptions and the sensitivity of the MSR value at September 30, 2012, and December 31, 2011, to changes in these assumptions follows:

For MSRs under the amortization method, a summary of key assumptions and the sensitivity of the MSR value at September 30, 2012, and December 31, 2011, to changes in these assumptions follows:

Total servicing fees included in mortgage banking income amounted to $11.3 million and $12.1 million for the three-month periods ended September 30, 2012 and 2011, respectively. For the nine-month periods ended September 30, 2012 and 2011, servicing fees totaled $34.7 million and $37.1 million, respectively.

Automobile Loans and Leases

In the 2012 first quarter, automobile loans totaling $1.3 billion were transferred to a trust in a securitization transaction in exchange for $1.3 billion of net proceeds. The securitization and resulting sale of all underlying securities qualified for sale accounting. As a result of this transaction, Huntington recognized a $23.0 million gain which is reflected in other noninterest income on the Condensed Consolidated Statement of Income and recorded a $19.9 million servicing asset which is reflected in accrued income and other assets on the Condensed Consolidated Balance Sheet.

$1.3 billion of automobile loans were transferred from the automobile loan portfolio to loans held for sale during the 2012 second quarter in preparation of a securitization that was completed in October 2012. The securitization and resulting sale of all underlying securities qualified for sale accounting. As a result of this transaction, in the 2012 fourth quarter, Huntington recognized a gain of approximately $17 million.

Huntington has retained servicing responsibilities on sold automobile loans and receives annual servicing fees and other ancillary fees on the outstanding loan balances. Automobile loan servicing rights are accounted for using the amortization method. A servicing asset is established at fair value at the time of the sale. The servicing asset is then amortized against servicing income. Impairment, if any, is recognized when carrying value exceeds the fair value as determined by calculating the present value of expected net future cash flows. The primary risk characteristic for measuring servicing assets is payoff rates of the underlying loan pools. Valuation calculations rely on the predicted payoff assumption and, if actual payoff is quicker than expected, then future value would be impaired.

Changes in the carrying value of automobile loan servicing rights for the three-month and nine-month periods ended September 30, 2012 and 2011, and the fair value at the end of each period were as follows:

A summary of key assumptions and the sensitivity of the automobile loan servicing rights value at September 30, 2012, and December 31, 2011, to changes in these assumptions follows:

Servicing income, net of amortization of capitalized servicing assets, amounted to $2.2 million and $0.3 million for the three-month periods ending September 30, 2012, and 2011, respectively. For the nine-month periods ended September 30, 2012 and 2011, servicing income, net of amortization of capitalized serving assets, amounted to $5.6 million and $1.0 million, respectively.
