based on the valuation techniques used and the sensitivity of financial statement amounts to the methods , assumptions , and estimates underlying those amounts , management has determined that the accounting policies with respect to the allowance for credit losses , goodwill and other intangible assets , deferred tax assets , and fair value are critical accounting policies . these policies are considered critical because they relate to accounting areas that require the most subjective or complex judgments , and , as such , could be most subject to revision as new information becomes available . the allowance for credit losses represents management 's estimate of credit losses inherent in the loan portfolio as of the balance sheet date . determining the amount of the allowance for credit losses is considered a critical accounting estimate because it requires significant judgment and the use of estimates related to the amount and timing of expected future cash flows on impaired loans , estimated losses on pools of homogeneous loans based on historical loss experience , and consideration of current economic trends and conditions , all of which may be susceptible to significant change . the loan portfolio also represents the largest asset type on the consolidated balance sheets . note 1 to the consolidated financial statements describes the methodology used to determine the allowance for credit losses . a discussion of the factors driving changes in the amount of the allowance for credit losses is included in the asset quality - provision for credit losses

that also lack physical substance but can be distinguished from goodwill because of contractual or other legal rights or because the asset is capable of being sold or exchanged either on its own or in combination with a related contract , asset or liability . goodwill and other intangible assets are required to be recorded at fair value at inception . determining fair value is subjective , requiring the use of estimates , assumptions and management judgment . goodwill and other intangible assets with indefinite lives are tested at least annually for impairment , usually during the third quarter , or on an interim basis if circumstances dictate . intangible assets that have finite lives are amortized over their estimated useful lives and also are subject to impairment testing . impairment testing requires that the fair value of each of the company 's reporting units be compared to the carrying amount of its net assets , including goodwill . the company 's reporting units were identified based on an analysis of each of its individual operating segments ( i.e . , the bank and insurance subsidiaries ) . if the fair value of a reporting unit is less than book value , an expense may be required to write down the related goodwill or purchased intangibles to record an impairment loss . 32 deferred tax assets and liabilities are determined by applying the applicable federal and state income tax rates to cumulative temporary differences . these temporary differences represent differences between financial statement carrying amounts and the corresponding tax bases of certain assets and liabilities . deferred taxes result from such temporary differences . a valuation allowance , if needed , reduces deferred tax assets to the expected amount most likely to be realized . realization of deferred tax assets is dependent on the generation of a sufficient level of future taxable income , recoverable taxes paid in prior years and tax planning strategies . the company evaluates all positive and negative evidence before determining if a valuation allowance is deemed necessary regarding the realization of deferred tax assets . the company measures certain financial assets and liabilities at fair value , with the measurements made on a recurring or nonrecurring basis . significant financial instruments measured at fair value on a recurring basis are investment securities . impaired loans and other real estate owned are significant financial instruments measured at fair value on a nonrecurring basis . fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability ( an exit price ) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date . in determining fair value , the company is required to maximize the use of observable inputs and minimize the use of unobservable inputs , reducing subjectivity
