1Investments amounting to $274.8 million at December 31, 2025 and $169.5 million at December 31, 2024, were measured at fair value using the net asset value per share (or its practical expedient) and have not been classified in the fair value hierarchy. These investments are subject to restrictions on redemption, and the timing of liquidations of the underlying assets is unknown at each reporting period. The fair value amounts presented in this table are intended to permit reconciliation of the fair value hierarchy to total assets measured at fair value.

1Other is comprised of broker quotes or other third-party pricing for which there is a lack of transparency into the inputs used to develop the valuations. The quantitative details of these unobservable inputs is neither provided to us, nor reasonably available to us, and therefore are not included in the tables above.

For the securities in the tables above valued using a DCF analysis, we apply an illiquidity spread in our determination of fair value. An increase in this assumption would result in a lower fair value measurement.

About Fair Value Disclosures

Fair value disclosures classify all assets and liabilities measured at fair value into a three-level hierarchy: Level 1 (quoted market prices), Level 2 (observable inputs like yield curves), and Level 3 (unobservable inputs requiring management estimates). The proportion of Level 3 assets directly reflects how much of the balance sheet depends on internal models rather than market evidence.

Key signals: a growing Level 3 balance relative to total fair-value assets increases valuation uncertainty and earnings volatility risk. Watch for transfers between levels — assets moving from Level 2 to Level 3 often signal deteriorating market liquidity. Unrealized gains and losses on Level 3 positions flow through earnings or other comprehensive income, so large swings deserve scrutiny. For financial institutions, examine the sensitivity disclosures that show how Level 3 valuations change under alternative assumptions. Compare the fair value of debt against its carrying amount to gauge hidden leverage.
