MSR

The activity in the MSR is detailed in the table below for the periods presented ($ in thousands):

	Years Ended December 31,
	2021			2020
Balance at beginning of period	$	66,464		$	79,394
Origination of servicing assets		28,125			29,805
Change in fair value:
Due to market changes		13,258			(26,147	)
Due to runoff		(20,160	)		(16,588	)
Balance at end of period	$	87,687		$	66,464

Trustmark determines the fair value of the MSR using a valuation model administered by a third party that calculates the present value of estimated future net servicing income. Trustmark considers the conditional prepayment rate (CPR), which is an estimated loan prepayment rate that uses historical prepayment rates for previous loans similar to the loans being evaluated, and the discount rate in determining the fair value of the MSR. An increase in either the CPR 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. At December 31, 2021, the fair value of the MSR included an assumed average prepayment speed of 12 CPR and an average discount rate of 9.56% compared to an assumed average prepayment speed of 15 CPR and an average discount rate of 9.53% at December 31, 2020. 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 the MSR requires significant management judgment.

Mortgage Loans Sold/Serviced

During 2021, 2020 and 2019, Trustmark sold $2.286 billion, $2.532 billion and $1.404 billion, respectively, of residential mortgage loans. Gain on sales of loans, net totaled $56.0 million in 2021, $110.9 million in 2020 and $30.3 million in 2019. Trustmark receives annual servicing fee income approximating 0.32% of the outstanding balance of the underlying loans, which totaled $25.1 million in 2021, $23.3 million in 2020 and $22.6 million in 2019. The gains on the sale of residential mortgage loans and the annual servicing fee are both recorded to noninterest income in mortgage banking, net in the accompanying consolidated statements of income. The investors and the securitization trusts have no recourse to the assets of Trustmark for failure of debtors to pay when due.

The table below details the mortgage loans sold and serviced for others at December 31, 2021 and 2020 ($ in thousands):

Federal National Mortgage Association	$	4,709,584	$	4,629,670
Government National Mortgage Association		3,194,373		2,960,760

Other		13,272		16,201
Total mortgage loans sold and serviced for others	$	7,953,200	$	7,657,090

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 loan sold was 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, loans that do not meet investor guidelines, loans in which the appraisal does not support the value and/or loans obtained through fraud by the borrowers or other third parties. Generally, putback requests may be made until the loan is paid in full. However, mortgage loans delivered to Federal National Mortgage Association (FNMA) and Federal Home Loan Mortgage Corporation (FHLMC) on or after January 1, 2013 are subject to the Representations and Warranties Framework, which provides that FNMA and FHLMC will not exercise their remedies, including a putback request, for breaches of certain selling representations and warranties if the mortgage loans satisfy certain criteria, such as payment history or quality control review.

When a putback request is received, Trustmark evaluates the request and takes appropriate actions based on the nature of the request. Trustmark is required by FNMA and FHLMC to provide a response to putback requests within 60 days of the date of receipt. The total mortgage loan servicing putback expenses were included in other expense. At both December 31, 2021 and 2020, Trustmark had a reserve for mortgage loan servicing putback expenses of $500 thousand.

There is inherent uncertainty in reasonably estimating the requirement for reserves against potential 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. Trustmark believes that it has appropriately reserved for potential mortgage loan servicing putback requests.
