Note 6 – | Mortgage Banking
Trustmark recognizes as assets the rights to service mortgage loans based on the estimated fair value of the mortgage servicing rights (MSR) when loans are sold and the associated servicing rights are retained. Trustmark also incorporates a hedging strategy, which utilizes a portfolio of derivative instruments to achieve a return that would substantially offset the changes in fair value of MSR attributable to interest rates. Changes in the fair value of these derivative instruments are recorded in noninterest income in mortgage banking, net and are offset by changes in the fair value of MSR. The fair value of MSR is determined using discounted cash flow techniques benchmarked against third-party valuations. Estimates of fair value involve several assumptions, including key valuation assumptions about market expectations of future prepayment rates, interest rates and discount rates which are provided by a third party firm. By way of example, an increase in either the prepayment speed or discount rate assumption will result in a decrease in the fair value of the MSR, while a decrease in either assumption will result in an increase in the fair value of the MSR. In recent years, there have been significant market-driven fluctuations in loan prepayment speeds and discount rates. These fluctuations can be rapid and may continue to be significant. Therefore, estimating prepayment speed and/or discount rates within ranges that market participants would use in determining the fair value of MSR requires significant management judgment. Trustmark utilizes a portfolio of exchange-traded derivative instruments, such as Treasury note futures contracts and option contracts, to achieve a fair value return that offsets the changes in fair value of the MSR attributable to interest rates. These transactions are considered freestanding derivatives that do not otherwise qualify for hedge accounting. Changes in the fair value of these exchange-traded derivative instruments, including administrative costs, are recorded in noninterest income in mortgage banking, net and are offset by the changes in the fair value of the MSR. The MSR fair value represents the present value of future cash flows, which among other things includes decay and the effect of changes in interest rates. Ineffectiveness of hedging the MSR fair value is measured by comparing the change in value of hedge instruments to the change in the fair value of the MSR asset attributable to changes in interest rates and other market driven changes in valuation inputs and assumptions. The impact of this strategy resulted in a net negative ineffectiveness of $1.8 million and $2.7 million for the three and nine months ended September 30, 2012, respectively, compared to a net positive ineffectiveness of $2.8 million and $4.8 million for the three and nine months ended September 30, 2011, respectively. See the section captioned "Noninterest Income" in Management's Discussion and Analysis for further analysis of mortgage banking revenues, which includes the table for net hedge ineffectiveness. The activity in MSR is detailed in the table below ($ in thousands):

Trustmark is subject to losses in its loan servicing portfolio due to loan foreclosures. Trustmark has obligations to either repurchase the outstanding principal balance of a loan or make the purchaser whole for the economic benefits of a loan if it is determined that the loans sold were in violation of representations or warranties made by Trustmark at the time of the sale, herein referred to as mortgage loan servicing putback expenses. Such representations and warranties typically include those made regarding loans that had missing or insufficient file documentation and/or loans obtained through fraud by borrowers or other third parties. The total mortgage loan servicing putback expenses incurred by Trustmark during the first nine months of 2012 and 2011 were $7.2 million and $2.5 million, respectively. During the second quarter of 2012, Trustmark updated its quarterly analysis of mortgage loan repurchase exposure. This analysis, along with recent mortgage industry trends, resulted in Trustmark providing an additional reserve of approximately $4.0 million in the second quarter. At September 30, 2012 and December 31, 2011, accrued mortgage loan servicing putback expenses were $8.6 million and $4.3 million, respectively. There is inherent uncertainty in reasonably estimating the requirement for reserves against future mortgage loan servicing putback expenses. Future putback expenses are dependent on many subjective factors, including the review procedures of the purchasers and the potential refinance activity on loans sold with servicing released and the subsequent consequences under the representations and warranties. Notwithstanding significant changes in future behaviors and the demand patterns of investors, Trustmark believes that it has appropriately reserved for potential mortgage loan repurchase requests.
