The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reported periods. Actual results could differ from those estimates. A discussion of critical accounting policies and the possible effects of changes in estimates on our consolidated financial statements is included in Note 2 — Basis of Presentation and Note 3 — Summary of Significant Accounting Policies included in Part I, Item 1 of this Quarterly Report on Form 10-Q.

We have elected the fair value option of accounting for a significant portion of the assets and some of the liabilities on our balance sheet, and the majority of these assets and liabilities utilize Level 3 valuation inputs, which require a significant level of estimation uncertainty. See Note 6 in Part I, Item 1 of this Quarterly Report on Form 10-Q, for additional information on our assets and liabilities accounted for at fair value at September 30, 2026, including the significant inputs used to estimate their fair values and the impact the changes in their fair values had to our financial condition and results of operations. See Note 6 in Part II, Item 8 of our Annual Report on Form 10-K for the year ended December 31, 2025, incorporated herein by reference, for the same information on these assets and liabilities as of December 31, 2025. Periodic fluctuations in the values of these assets and liabilities are inherently volatile and thus can lead to significant period-to-period GAAP earnings volatility.

Additional detail on our critical accounting estimates is included in Part II, Item 7 of our Annual Report on Form 10-K for the year ended December 31, 2025, under the heading "Critical Accounting Estimates."
