MSR

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

	Three Months Ended March 31,
	2023			2022
Balance at beginning of period	$	129,677		$	87,687
Origination of servicing assets		2,646			5,128
Change in fair value:
Due to market changes		(3,972	)		22,020
Due to run-off		(1,145	)		(3,785	)
Balance at end of period	$	127,206		$	111,050

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, the float rate, which is the interest rate earned on escrow balances, and the discount rate as some of the primary assumptions used 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. An increase in the float rate will result in an increase in the fair value of the MSR, while a decrease in the float rate will result in a decrease in the fair value of the MSR. At March 31, 2023, the fair value of the MSR included an assumed average prepayment speed of 8 CPR and an average discount rate of 10.08% compared to an assumed average prepayment speed of 9 CPR and an average discount rate of 9.56% at March 31, 2022.

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 certain instances in which FNMA and FHLMC will not exercise their remedies, including a putback request, for breaches of certain selling representations and warranties, such as payment history and 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 are included in other expense. At both March 31, 2023 and 2022, 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.
