Fair Value Disclosures [Abstract]

Fair Value Measurement Methodologies

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 7, Mortgage Banking Operations.

Level 3 recurring fair value measurement.

Derivatives

Futures and Options

Fair value is based on closing exchange prices.

Level 1 recurring fair value measurement.

Forward sale commitments Interest rate swaps

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.

Interest rate lock commitments

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 •       Fall-out factor

Level 3 recurring fair value measurement.

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:

			At June 30, 2022																		At December 31, 2021
(in thousands)			Fair Value						Aggregate Unpaid Principal Balance						Fair Value Less Aggregated Unpaid Principal Balance						Fair Value						Aggregate Unpaid Principal Balance						Fair Value Less Aggregated Unpaid Principal Balance
