Use of Estimates | Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change relate to the determination of the allowance for loan losses and the valuation of real estate acquired in connection with foreclosures or in satisfaction of loans, the valuation of loans acquired with indication of impairment, the valuation of the FDIC indemnification asset (prior to December 31, 2017) and other-than-temporary impairments (OTTI) and fair values of financial instruments. In connection with the determination of the allowance for loan losses and the valuation of foreclosed assets held for sale, management obtains independent appraisals for significant properties. The valuation of the FDIC indemnification asset was determined in relation to the fair value of assets acquired through FDIC-assisted transactions for which cash flows are monitored on an ongoing basis. In addition, the Company considers that the determination of the carrying value of goodwill and intangible assets involves a high degree of judgment and complexity.
