There were no sales of marketable investment securities during the three or six months ended June 30, 2026 or 2025 and therefore no realized gains or losses.

The Company evaluates its available-for-sale debt securities for credit losses at each reporting date. As of June 30, 2026, the Company’s available-for-sale portfolio consisted of U.S. Treasury bills with maturities due within one year. The Company concluded that any unrealized losses were not attributable to credit and, accordingly, no allowance for credit losses was recorded and no impairment was recognized in earnings during the three or six months ended June 30, 2026 or 2025.
