FAIR VALUE MEASUREMENT

3 Months Ended

Mar. 31, 2023

FAIR VALUE MEASUREMENT:

The term "fair value" is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. A fair value measurement assumes that the transaction to sell the asset or transfer the liability occurs in the principal market for the asset or liability or, in the absence of a principal market, the most advantageous market for the asset or liability. The Company's approach is to maximize the use of observable inputs and minimize the use of unobservable inputs when developing fair value measurements.

Fair Value Hierarchy

A three-level valuation hierarchy has been established under ASC 820 for disclosure of fair value measurements. The valuation hierarchy is based on the observability of inputs to the valuation of an asset or liability as of the measurement date. A financial instrument’s categorization within the valuation hierarchy is based on the lowest level of input that is significant to the fair value measurement. The levels are defined as follows:

• Level 1 – Quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity can access at the measurement date. An active market for the asset or liability is a market in which transactions for the asset or liability take place with sufficient frequency and volume to provide pricing information on an ongoing basis.

• Level 2 – Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. This includes quoted prices for similar assets and liabilities in active markets and inputs that are observable for the asset or liability for substantially the full term of the financial instrument.

• Level 3 – Unobservable inputs for the asset or liability. These inputs reflect the Company's assumptions of what market participants would use in pricing the asset or liability.

The Company's policy regarding transfers between levels of the fair value hierarchy is that all transfers are assumed to occur at the end of the reporting period.

Estimation of Fair Value

Fair value is based on quoted market prices, when available. In cases where a quoted price for an asset or liability is not available, the Company uses valuation models to estimate fair value. These models incorporate inputs such as forward yield curves, loan prepayment assumptions, expected loss assumptions, market volatilities and pricing spreads utilizing market-based inputs where readily available. The Company believes its valuation methods are appropriate and consistent with those that would be used by other market participants. However, imprecision in estimating unobservable inputs and other factors may result in these fair value measurements not reflecting the amount realized in an actual sale or transfer of the asset or liability in a current market exchange.

The following table summarizes the fair value measurement methodologies, including significant inputs and assumptions and classification of the Company's assets and liabilities valued at fair value on a recurring basis.

Asset/Liability class

Valuation methodology, inputs and assumptions

Classification

Investment securities

Trading securities

Fair Value is based on quoted prices in an active market.

Level 1 recurring fair value measurement.

Investment securities AFS

Observable market prices of identical or similar securities are used where available.

Level 2 recurring fair value measurement.

If market prices are not readily available, value is based on discounted cash flows using the following significant inputs:

• Expected prepayment speeds

• Estimated credit losses

• Market liquidity adjustments

Level 3 recurring fair value measurement.

LHFS

Single family loans, excluding loans transferred from held for investment

Fair value is based on observable market data, including:

• Quoted market prices, where available

• Dealer quotes for similar loans

• Forward sale commitments

Level 2 recurring fair value measurement.

When not derived from observable market inputs, fair value is based on discounted cash flows, which considers the following inputs:

• Benchmark yield curve

• Estimated discount spread to the benchmark yield curve

• Expected prepayment speeds

Estimated fair value classified as Level 3.

Mortgage servicing rights

Single family MSRs

For information on how the Company measures the fair value of its single family MSRs, including key economic assumptions and the sensitivity of fair value to changes in those assumptions, see Note 6, Mortgage Banking Operations.

Fair value is based on quoted prices for identical or similar instruments, when available. When quoted prices are not available, fair value is based on internally developed modeling techniques, which require the use of multiple observable market inputs including:

• Forward interest rates
• Interest rate volatilities

Level 2 recurring fair value measurement.

IRLC

The fair value considers several factors including:

• Fair value of the underlying loan based on quoted prices in the secondary market, when available.

• Value of servicing

Level 3 Recurring Fair Value Measurements

The Company's level 3 recurring fair value measurements consist of investment securities AFS, single family MSRs, single family LHFI where fair value option was elected, certain single family LHFS and interest rate lock commitments, which are accounted for as derivatives. For information regarding fair value changes and activity for single family MSRs during the quarters ended March 31, 2023 and 2022, see Note 6, Mortgage Banking Operations of this Quarterly Report on Form 10-Q.

The fair value of IRLCs considers several factors, including the fair value in the secondary market of the underlying loan resulting from the exercise of the commitment, the expected net future cash flows related to the associated servicing of the loan (referred to as the value of servicing) and the probability that the commitment will not be converted into a funded loan (referred to as a fall-out factor). The fair value of IRLCs on LHFS, while based on interest rates observable in the market, is highly dependent on the ultimate closing of the loans. The significance of the fall-out factor to the fair value measurement of an individual IRLC is generally highest at the time that the rate lock is initiated and declines as closing procedures are performed and the underlying loan gets closer to funding. The fall-out factor applied is based on historical experience. The value of servicing is impacted by a variety of factors, including prepayment assumptions, discount rates, delinquency rates, contractually specified servicing fees, servicing costs and underlying portfolio characteristics. Because these inputs are not observable in market trades, the fall-out factor and value of servicing are considered to be level 3 inputs. The fair value of IRLCs decreases in

value upon an increase in the fall-out factor and increases in value upon an increase in the value of servicing. Changes in the fall-out factor and value of servicing do not increase or decrease based on movements in other significant unobservable inputs.

The Company recognizes unrealized gains and losses from the time that an IRLC is initiated until the gain or loss is realized at the time the loan closes, which generally occurs within 30-90 days. For IRLCs that fall out, any unrealized gain or loss is reversed, which generally occurs at the end of the commitment period. The gains and losses recognized on IRLC derivatives generally correlates to volume of single family interest rate lock commitments made during the reporting period (after adjusting for estimated fallout) while the amount of unrealized gains and losses realized at settlement generally correlates to the volume of single family closed loans during the reporting period.

The Company uses the discounted cash flow model to estimate the fair value of certain loans that have been transferred from held for sale to held for investment and single family LHFS when the fair value of the loans is not derived using observable market inputs. The key assumption in the valuation model is the implied spread to benchmark interest rate curve. The implied spread is not directly observable in the market and is derived from third party pricing which is based on market information from comparable loan pools. The fair value estimate of single family loans that have been transferred from held for sale to held for investment are sensitive to changes in the benchmark interest rate which might result in a significantly higher or lower fair value measurement.

The Company transferred certain loans from held for sale to held for investment. These loans were originated as held for sale loans where the Company had elected fair value option. The Company determined these loans to be level 3 recurring assets as the valuation technique included a significant unobservable input. The total amount of held for investment loans where fair value option election was made was $5.2 million and $5.9 million at March 31, 2023 and December 31, 2022, respectively.

Nonrecurring Fair Value Measurements

Certain assets held by the Company are not included in the tables above, but are measured at fair value on a periodic basis. These assets include certain LHFI and OREO that are carried at the lower of cost or fair value of the underlying collateral, less the estimated costs to sell. The estimated fair values of real estate collateral are generally based on internal evaluations and appraisals of such collateral, which use the market approach and income approach methodologies. We have omitted disclosure related to quantitative inputs given the insignificance of assets measured on a nonrecurring basis.

The fair value of commercial properties is generally based on third-party appraisals that consider recent sales of comparable properties, including their income-generating characteristics, adjusted (generally based on unobservable inputs) to reflect the general assumptions that a market participant would make when analyzing the property for purchase. The Company uses a fair value of collateral technique to apply adjustments to the appraisal value of certain commercial LHFI that are collateralized by real estate.

The Company uses a fair value of collateral technique to apply adjustments to the stated value of certain commercial LHFI that are not collateralized by real estate and to the appraisal value of OREO.

Residential properties are generally based on unadjusted third-party appraisals. Factors considered in determining the fair value include geographic sales trends, the value of comparable surrounding properties as well as the condition of the property.

These adjustments include management assumptions that are based on the type of collateral dependent loan and may increase or decrease an appraised value. Management adjustments vary significantly depending on the location, physical characteristics and income producing potential of each individual property. The quality and volume of market information available at the time of the appraisal can vary from period-to-period and cause significant changes to the nature and magnitude of the unobservable inputs used. Given these variations, changes in these unobservable inputs are generally not a reliable indicator for how fair value will increase or decrease from period to period.

The following table presents assets classified as Level 3 that had changes in their recorded fair value for the periods indicated and what we still held at the end of the respective reporting period:

Fair Value Option

Single family loans held for sale accounted under the fair value option are measured initially at fair value with subsequent changes in fair value recognized in earnings. Gains and losses from such changes in fair value are recognized in net gain on mortgage loan origination and sale activities within noninterest income. The change in fair value of loans held for sale is

primarily driven by changes in interest rates subsequent to loan funding and changes in fair value of the related servicing asset, resulting in revaluations adjustments to the recorded fair value. The use of the fair value option allows the change in the fair value of loans to more effectively offset the change in fair value of derivative instruments that are used as economic hedges of loans held for sale.

The following table presents the difference between the aggregate fair value and the aggregate unpaid principal balance of loans held for sale accounted for under the fair value option:
