 to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The Thrift Plan Committee is responsible for establishing an accounting and financial reporting process for fair value measurements. The Thrift Plan Committee may look to the investment manager, trustee, or other service provider to assist in the mechanics of the valuation. However, the Thrift Plan Committee is responsible for obtaining sufficient information to evaluate and independently challenge the valuation.

Purchases and sales of securities are recorded on a trade-date basis. Interest income is recorded on the accrual basis. Dividends are recorded on the ex-dividend date. Net appreciation includes the Plan’s gains and losses on investments bought and sold as well as held during the year.

The Plan uses a fair value hierarchy to prioritize the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are described as follows:

#### Level 1
- Quoted prices for identical instruments in active markets.

#### Level 2
- Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are inactive; inputs other than quoted prices that are observable for the asset or liability; and inputs that are derived principally from or corroborated by observable market data by correlation or other means. If the asset or liability has a specified (contractual) term, the Level 2 input must be observable for substantially the full term of the asset or liability.

#### Level 3
- Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable.

The Plan Sponsor generally uses quoted market prices to determine fair value, and classifies such items in Level 1.

The asset’s and liability’s fair value measurement level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Valuation techniques used need to maximize the use of observable inputs and minimize the use of unobservable inputs.

Following is a description of the valuation methodologies used for assets measured at fair value. There have been no changes in methodologies used at December 31, 2024 and 2023.
