EBP, Investment, Fair Value and NAV Fair Value Measurements:
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 (exit price). The inputs used to measure fair value are classified into the following hierarchy:
Level 1Unadjusted quoted prices in active markets for identical assets or liabilities
Level 2Unadjusted quoted prices in active markets for similar assets or liabilities, or
Unadjusted quoted prices for identical or similar assets or liabilities in markets that are not active, or
Inputs other than quoted prices that are observable for the asset or liability, or
Inputs that are derived principally from or corroborated by observable market data by correlation or other means
Level 3Unobservable inputs for the asset or liability
The following tables set forth by level, within the fair value hierarchy, the Plan’s investments at fair value as of December 31, 2025 and 2024:

(a)The common/collective trusts are measured at fair value using the net asset value per share (or its equivalent) practical expedient and have not been categorized in the fair value hierarchy. The fair value amount presented in this table is intended to permit reconciliation of the fair value hierarchy to the amount presented on the Statements of Net Assets Available for Benefits.

The asset’s 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 maximize the use of observable inputs and minimize the use of unobservable inputs. See Note 3 for a description of the valuation methodologies for assets measured at fair value.

During 2025, the Plan’s investments (including gains and losses on investments bought and sold, as well as held during the year) appreciated in value by $102,451,247.
