Use of estimates

The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.

#### Note 3 – Fair Value Measurements
The fair value hierarchy prioritizes the inputs to valuation techniques used to measure fair value. The three levels of valuation hierarchy are described below:

Level 1 – Inputs to the valuation methodology are unadjusted quoted prices for identical assets or liabilities in active markets that the Plan has the ability to access.

Level 2 – Inputs to the valuation methodology include:

• quoted prices for similar assets or liabilities in active markets;

• quoted prices for identical or similar assets or liabilities in inactive markets;

• 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.

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 – Inputs to the valuation methodology are unobservable and significant to the fair value measurement.

Following is a description of the valuation methodologies used for assets measured at fair value by the Plan. There have been no changes in the methodologies used at December 31, 2024 and 2023. During the year ended December 31, 2024, there were no transfers of financial instruments into or out of Level 3.

Collective investment funds : Valued at the NAV of shares held by the Plan at year end, as a practical expedient of fair value. The NAV is provided by the collective investment funds' trustee, which is BOKF, NA, and is derived from market quotes for identical assets. The practical expedient would not be used if it is determined to be probable that the fund will sell the investment for an amount different from the reported NAV. The fair value of
