(1)    Consists of registered money market funds and an equity index fund held in deferred compensation trusts. These investments represent the net asset value at the close of business of the period based on the last trade or official close of an active market or exchange.
(2)    Foreign currency and commodity derivatives are estimated using pricing models with market-based inputs, which take into account the present value of estimated future cash flows.
(3) The NuScale warrant liabilities are comprised of public and private placement warrants redeemable by NuScale under certain conditions, both measured using the price of the public warrants. The private placement warrants are not publicly traded and have been classified as Level 2 measurements while the public warrants are classified as Level 1.
We have measured certain other impaired assets at fair value on a nonrecurring basis. The following summarizes information about financial instruments that are not required to be measured at fair value:

(1)    Cash consists of bank deposits. Carrying amounts approximate fair value.
(2)    Cash equivalents and marketable securities, current 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.
