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. Depending on the nature of the asset or liability, various techniques and assumptions can be used to estimate fair value. The definition of the fair value hierarchy is as follows:
Level 1 - Quoted prices in active markets for identical assets and liabilities.
Level 2 - Observable inputs other than quoted prices in active markets for similar assets and liabilities.
Level 3 - Inputs for which significant valuation assumptions are unobservable in a market and therefore value is based on the best available data, some of which is internally developed and considers risk premiums that a market participant would require.
The following is a description of the valuation methodologies used for assets measured at fair value. There have been no changes to the methodologies used at September 30, 2025 and 2024.
The Plan's assets are invested in shares of registered investment companies, employer securities, common collective trust funds, pooled separate accounts and an investment in insurance contract (reported at contract value).
Shares of registered investment companies: Consists of both equity and fixed income mutual funds. Valued at quoted market prices that represent the net asset value ("NAV") of shares held by the Plan at year end.

Employer securities: Certain assets of the Plan are invested in employer securities through a unitized stock fund, which includes Company Class B common stock and investments in a money market fund for liquidity purposes. Employer securities are valued at the closing price reported on the New York Stock Exchange. Money market funds are stated at cost, which approximates fair value.
Common collective trust funds: Consist of pools of investments used by institutional investors to obtain exposure to equity and fixed income markets. Common collective trust funds held by the Plan invest in target date funds. Shares held in common collective trusts are reported at the NAV of units held at year end. The NAV is determined by the total value of fund assets divided by the total number of units of the fund owned.
Pooled separate accounts: Assets of each separate account are pooled with the funds of other investors and invested in stocks, bonds, mutual funds or collective trusts. Shares held in pooled separate accounts are reported at the NAV of units held at year end. The NAV is determined by the total value of fund assets divided by the total number of units of the fund owned.

The fair value amounts presented in this table are intended to permit reconciliation of the fair value hierarchy to the Statements of Net Assets Available for Benefits.
