SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The accompanying Plan financial statements were prepared in conformity with U.S. generally accepted accounting principles (GAAP).

Plan investments, other than fully benefit-responsive investment contracts, are stated at fair value (see Note 3). Fully benefit-responsive investment contracts are valued at contract value, which is the relevant measurement attribute because contract value

is the amount participants would receive if they were to initiate permitted transactions under the terms of the Plan. Purchases and sales of all securities are recorded on a trade-date basis.

Notes receivable from participants are valued at their outstanding balances.

Use of Estimates

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

Risks and Uncertainties

The Plan invests in various investment securities. Investment securities are exposed to various risks, such as interest rate, market, and credit risks. Due to the level of risk associated with certain investment securities, changes in the values of investment securities will occur in the near term that could materially affect participants’ account balances and the amounts reported in the Statement of Net Assets Available for Benefits.

The Plan provides for investment in TRV’s common stock fund; however, no new contributions (including Company match contributions) or investment transfers into the TRV common stock fund are allowed. Dividends paid on shares in participants’ accounts invested in the TRV common stock fund continue to be reinvested in the TRV common stock fund, unless participants elect to receive dividends in cash. At both December 31, 2025 and 2024, approximately 4% of the Plan’s total assets were invested in the common stock of TRV. The underlying value of the TRV common stock is entirely dependent upon the performance of the Company and the market’s evaluation of such performance.

Income Recognition

Interest income is recorded on the accrual basis. Dividends are recorded on the ex-dividend date. Net appreciation in fair value of investments includes gains and losses on investments sold during the year as well as appreciation and depreciation of the investments held at the end of the year.

Payment of Benefits

Benefit payments are recorded when paid.
