Fair Value Fair Value
The preparation of the Company’s unaudited condensed consolidated financial statements in accordance with GAAP requires certain assets and liabilities to be reflected at their fair value and others to be reflected on another basis, such as an adjusted historical cost basis. The Company’s assets and liabilities carried at fair value have been classified within one of three levels of a hierarchy established by GAAP. The following are the levels of the hierarchy and a brief description of the type of valuation information (“valuation inputs”) that qualifies a financial asset or liability for each level:

•Level 1 – Unadjusted quoted prices for identical assets or liabilities in active markets.
•Level 2 – Valuation inputs other than Level 1 that are based on observable market data. These include: quoted prices for similar assets in active markets, quoted prices for identical assets in inactive markets, valuation inputs that are observable that are not prices (such as interest rates and credit risks) and valuation inputs that are derived from or corroborated by observable markets.
•Level 3 – Developed from unobservable data, reflecting the Company’s assumptions.

For a description of the methods and assumptions that are used to estimate the fair value and determine the fair value hierarchy classification of each class of financial instrument, see Note 5 ‘‘Fair Value’’ in the 2025 Form 10-K.
There were no financial liabilities measured at fair value on a recurring basis on the unaudited condensed consolidated balance sheets as of June 30, 2026 or December 31, 2025. Financial assets measured at fair value on a recurring basis on the unaudited condensed consolidated balance sheets as of June 30, 2026 and December 31, 2025 were as follows:

(1)It was not practical to estimate the fair value of these investments as they represent shares of unlisted companies.

Separate Accounts

Separate accounts assets relate to the Company’s large case pensions products and represent funds maintained to meet specific objectives of contract holders. Since contract holders bear the investment risk of these assets, a corresponding separate accounts liability has been established equal to the assets. Separate accounts assets and liabilities are carried at fair value and are included in other assets and other long-term liabilities, respectively, on the unaudited condensed consolidated balance sheets. During the six months ended June 30, 2026, changes in separate accounts assets and liabilities were not material. Separate accounts assets as of June 30, 2026 and December 31, 2025 were as follows:
