Notes to Financial Statements (continued)

December 31, 2025 and 2024

Use of Estimates

The preparation of financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and changes therein, and disclosure of contingent assets and liabilities. Actual results could differ from those estimates.

Investment Valuation and Income Recognition

Investments held by the Plan are stated at fair value. 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 (an exit price). See Note 3 for further discussion and disclosures related to fair value measurements.

Purchases and sales of securities are recorded on a trade-date basis. Interest income is recorded as earned. 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.

Participant Benefits

Benefit payments made to participants or transferred to another qualified plan at the direction of participants are recorded when paid.

Contributions

Participant contributions are allocated to participant accounts when the Company remits payroll deductions from eligible Plan participants. Participant and employer contributions are recorded in the year in which participant compensation is earned. As of December 31, 2025 and 2024, there were no unallocated employer contributions.

Forfeitures

Forfeitures of non-vested Company matching contributions are used to offset respective Company contributions generally for the Plan year in which such forfeitures occur. Company matching contributions were reduced by $4.1 million and $4.3 million during the years ended December 31, 2025 and 2024, respectively, by the offset of available forfeited balances. At December 31, 2025 and 2024, forfeited non-vested account balances available to offset future Company contributions totaled $0.9 million and $1.3 million, respectively.

Notes Receivable from Participants

Notes receivable from participants represent participant loans that are recorded at their unpaid principal balance plus any accrued but unpaid interest. Interest income on notes receivable from participants is recorded when it is earned. Related fees are recorded as administrative expenses and are expensed when they are incurred. If a participant ceases to make loan repayments and the plan administrator deems the participant loan to be a distribution, the participant loan balance is reduced and a benefit payment is recorded.

Risk and Uncertainties

The Plan provides for a number of investment options, primarily in stock, mutual funds and common trust funds with varying investment objectives and underlying security instruments including fixed income and equity securities. These investment securities are exposed to various risks including interest rate, market and credit risk. Due to the level of risk associated with certain investment securities, it is reasonably possible that changes in risks could materially affect participants, account balances and the amounts reported in the accompanying financial statements.
