These estimates are based on management’s best knowledge of current events and actions the Company may undertake in the future. Estimates are used in accounting for, among other items, fair value of financial instruments, the allowance for loan losses, mortgage servicing rights, foreclosed and repossessed assets, valuation of intangible assets arising from acquisitions, useful lives for depreciation and amortization, valuation of goodwill and long-lived assets, stock based compensation, deferred tax assets, uncertain income tax positions and contingencies. Management does not anticipate any material changes to estimates made herein in the near term. Factors that may cause sensitivity to the aforementioned estimates include but are not limited to: those items described under the caption “Risk Factors” in Item 1A of the accompanying transition report on Form 10-K for the year ended December 31, 2020 and external market factors such as market interest rates and employment rates, changes to operating policies and procedures, and changes in applicable banking regulations. Actual results may ultimately differ from estimates, although </span>management does not generally believe such differences would materially affect the consolidated financial statements in any individual reporting period.
