Basis of Presentation The Consolidated Financial Statements are prepared in conformity with accounting principles generally accepted in the U.S. (GAAP). In preparing the Consolidated Financial Statements, the Company is required to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses. Although the Company's estimates contemplate current conditions and how it expects them to change in the future, it is reasonably possible that actual conditions in 2024 could be worse than anticipated in those estimates, which could materially affect its results of operations and financial condition. The accounting for the allowance for credit losses (including loans and leases held for investment, investment securities available-for-sale and held-to-maturity), lending related commitments, goodwill, intangible assets, post-retirement benefit obligations, the fair value of financial instruments, and income taxes are subject to significant estimates. Among other effects, changes to these estimates could result in future impairments of investment securities, goodwill and intangible assets, the establishment of additional allowance and lending-related commitment reserves, changes in the fair value of financial instruments, as well as increased post-retirement benefits and income tax expense. All significant intercompany accounts and transactions were eliminated in consolidation.
