For additional information on the Company’s derivative instruments, see Note 1—“Organizations and Summary of Significant Accounting Policies,” Note 3—“Fair Value” and Note 6—“Derivatives” in the 2026 Form 10-K and Note 1—“Summary of Significant Accounting Policies,” Note 3—“Fair Value” and Note 7— “Offsetting of Derivatives and Securities Financing Agreements” herein.
The following table presents the notional amounts and fair values of the Company’s derivative instruments. While the notional amounts give an indication of the volume of the Company’s derivatives activity, the notional amounts significantly exceed, in the Company’s view, the possible losses that could arise from such transactions. For most derivative contracts, the notional amount is not exchanged, rather it is a reference amount used to calculate payments.
