_________________________________________________________
(1) We recognized the fair value of our investment in NuScale on a mark-to-market basis based upon the prevailing price of their stock on our balance sheet dates. As of June 30, 2026, we no longer held an investment in NuScale. Our investment in NuScale consisted of 111 million shares as of December 31, 2025.
(2)     In February 2026, we entered into 3 variable price forward sale agreements (described elsewhere) for our NuScale shares. The fair value of these forward contracts, which met the definition of a derivative, represented the difference between
the closing price of NuScale at the balance sheet date and the year-to-date settlement price calculated per the agreement plus a discounted growth assumption through the estimated settlement date. These forward contracts were fully settled in April 2026. As a result, no derivative asset remained as of June 30, 2026. The derivative assets were included in other current assets on the balance sheet as of December 31, 2025.

(1)    Cash consists of bank deposits. Carrying amounts approximate fair value.
(2)    Cash equivalents and marketable securities primarily consists of time deposits. Carrying amounts approximate fair value because of the short-term maturity of these instruments. Amortized cost is not materially different from the fair value.
(3)    The fair value of the Senior Notes was estimated based on quoted market prices and Level 2 inputs.
