Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 2 Summary of Significant Accounting Policies a) Acquisition activities—The Company accounts for business combinations under the acquisition method of accounting. Assets acquired and liabilities assumed are measured and recorded at fair value at the date of acquisition, including identifiable intangible assets. If the fair value of net assets acquired exceeds the fair value of consideration paid, a bargain purchase gain is recognized at the date of acquisition. Conversely, if the consideration paid exceeds the fair value of the net assets acquired, goodwill is recognized at the acquisition date. Fair values are subject to refinement for up to a maximum of one year after the closing date of an acquisition as information relative to closing date fair values becomes available. Adjustments recorded to the acquired assets and liabilities assumed are applied prospectively in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Update (“ASU”) 2015-16, Simplifying the Accounting for Measurement-Period Adjustments. The determination of the fair value of loans acquired takes into account credit quality deterioration and probability of loss therefore, the related ALL is not carried forward at the time of acquisition. Identifiable intangible assets are recognized separately if they arise from contractual or other legal rights or if they are separable (i.e., capable of being sold, transferred, licensed, rented, or exchanged separately from the entity). Deposit liabilities and the related depositor relationship intangible assets, known as the core deposit intangible assets, may be exchanged in observable exchange transactions. As a result, the core deposit intangible asset is considered identifiable, because the separability criterion has been met. b) Cash and cash equivalents—Cash and cash equivalents include cash, cash items, amounts due from other banks, amounts due from the Federal Reserve Bank of Kansas City, federal funds sold, and interest-bearing bank deposits. c) Investment securities—Investment securities may be classified in three categories: trading, available-for-sale and held-to-maturity. Management determines the appropriate classification at the time of purchase and reevaluates the classification at each reporting period. Any sales of available-for-sale securities are for the purpose of executing the Company’s asset/liability management strategy, reducing borrowings, funding loan growth, providing liquidity, or eliminating a perceived credit risk in a specific security. Held-to-maturity securities are carried at amortized cost and the available-for-sale securities are carried at estimated fair value. Unrealized gains or losses on securities available-for-sale are reported as accumulated other comprehensive income (loss) (“AOCI”), a component of shareholders’ equity, net of income tax. Gains and losses realized upon sales of securities are calculated using the specific identification method. Premiums and discounts are amortized to interest income over the estimated lives of the securities. Prepayment experience is periodically evaluated and a determination made regarding the appropriate estimate of the future rates of prepayment. When a change in a bond’s estimated remaining life is necessary, a corresponding adjustment is made in the related premium amortization or discount accretion. Purchases and sales of securities, including any corresponding gains or losses, are recognized on a trade-date basis and a receivable or payable is recognized for pending transaction settlements. Management evaluates all investments for OTTI on a quarterly basis, and more frequently when economic or market conditions warrant such evaluation. Impairment is considered to be other-than-temporary if it is likely that all amounts contractually due will not be received for debt securities and when there is no positive evidence indicating that an investment’s carrying amount is recoverable in the near term for equity securities. When impairment is considered other-than-temporary, the cost basis of the security is written down to fair value, with the impairment charge related to credit included in earnings, while the impairment charge related to all other factors is recognized in OCI. If the Company has the intent to sell the security or it is more likely than not that the Company will be required to sell the security, the entire amount of the OTTI is recorded in earnings. In evaluating whether the impairment is temporary or other than temporary, the Company considers, among other things, the severity and duration of the unrealized loss position; adverse conditions specifically related to the security; changes in expected future cash flows; downgrades in the rating of the security by a rating agency; the failure of the issuer to make scheduled interest or principal payments; whether the Company has the intent to sell the security; and whether it is more likely than not that the Company will be required to sell the security. d) Non-marketable securities—Non-marketable securities include Federal Reserve Bank ("FRB") stock, Federal Home Loan Bank ("FHLB") stock and non-negotiable certificates of deposit acquired in the acquisition of Pine River Bank Corporation, the parent company of Pine River Valley Bank (“Pine River”). These securities have been acquired for debt facility or regulatory purposes and are carried at cost. e) Loans receivable—Loans receivable include loans originated by the Company and loans that are acquired through acquisitions. Loans originated by the Company are carried at the principal amount outstanding, net of premiums, discounts, unearned income, and deferred loan fees and costs. Loan fees and certain costs of originating loans are deferred and the net amount is amortized over the contractual life of the related loans. Acquired loans are initially recorded at fair value and are accounted for under either Accounting Standards Codification (“ASC”) 310-30, Loans and Debt Securities Acquired with Deteriorated Credit Quality (see additional information below) or ASC Topic 310, Receivables. Non-refundable loan origination and commitment fees, net of direct costs of originating or acquiring loans, and fair value adjustments for acquired loans, are deferred and recognized over the remaining lives of the related loans in accordance with ASC 310-20. Acquired loans are recorded at their estimated fair value at the time of acquisition and accounted for under either ASC 310-30 or ASC 310. Estimated fair values of acquired loans are based on a discounted cash flow methodology that considers various factors including the type of loan and related collateral, the expected timing of cash flows, classification status, fixed or variable interest rate, term of loan and whether or not the loan is amortizing, and a discount rate reflecting the Company’s assessment of risk inherent in the cash flow estimates. Acquired 310-30 loans are grouped together according to similar characteristics such as type of loan, loan purpose, geography, risk rating and underlying collateral and are treated as distinct pools when applying various valuation techniques and, in certain circumstances, for the ongoing monitoring of the credit quality and performance of the pools. Each pool is accounted for as a single loan for which the integrity is maintained throughout the life of the asset. Discounts created when the loans are recorded at their estimated fair values at acquisition are accreted over the remaining term of the loan as an adjustment to the related loan’s yield. Similar to originated loans described below, the accrual of interest income on acquired loans that are not accounted for under ASC 310-30 is discontinued when the collection of principal or interest, in whole or in part, is doubtful. Interest income on acquired loans that are accounted for under ASC Topic 310 and interest income on loans originated by the Company is accrued and credited to income as it is earned using the interest method based on daily balances of the principal amount outstanding. However, interest is generally not accrued on loans 90 days or more past due, unless they are well secured and in the process of collection. Additionally, in certain situations, loans that are not contractually past due may be placed on non-accrual status due to the continued failure to adhere to contractual payment terms by the borrower coupled with other pertinent factors, such as insufficient collateral value or deficient primary and secondary sources of repayment. Accrued interest receivable is reversed when a loan is placed on non-accrual status and payments received generally reduce the carrying value of the loan. Interest is not accrued while a loan is on non-accrual status and interest income is generally recognized on a cash basis only after payment in full of the past due principal and collection of principal outstanding is reasonably assured. A loan may be placed back on accrual status if all contractual payments have been received, or sooner under certain conditions and collection of future principal and interest payments is no longer doubtful. In the event of borrower default, the Company may seek recovery in compliance with state lending laws, the respective loan agreements, and credit monitoring and remediation procedures that may include modifying or restructuring a loan from its original terms, for economic or legal reasons, to provide a concession to the borrower from their original terms due to borrower financial difficulties in order to facilitate repayment. Such restructured loans are considered “troubled debt restructurings” and are identified in accordance with ASC 310-40, Troubled Debt Restructurings by Creditors. Under this guidance, modifications to loans that fall within the scope of ASC 310-30 are not considered troubled debt restructurings, regardless of otherwise meeting the definition of a troubled debt restructuring. Loans receivable accounted for under ASC 310-30 The Company accounts for and evaluates acquired loans in accordance with the provisions of ASC 310-30, Loans and Debt Securities Acquired with Deteriorated Credit Quality. When loans exhibit evidence of credit deterioration since origination and it is probable at the date of acquisition that the Company will not collect all principal and interest payments in accordance with the terms of the loan agreement, the expected shortfall in future cash flows, as compared to the contractual amount due, is recognized as a non-accretable difference. Any excess of expected cash flows over the acquisition date fair value is known as the accretable yield, and is recognized as accretion income over the life of each pool. Contractual fees not expected to be collected are not included in ASC 310-30 contractual cash flows. Should fees be subsequently collected, the cash flows are accounted for as non 310-30 fee income in the period they are received. Loans that are accounted for under ASC 310-30 that meet the criteria for non-accrual of interest at the time of acquisition or subsequent to acquisition, may be considered performing, regardless of whether the client is contractually delinquent, if the timing and expected cash flows on such loans can be reasonably estimated and if collection of the new carrying value of such loans is expected. The expected cash flows of loans accounted for under ASC 310-30 are periodically remeasured utilizing the same cash flow methodology used at the time of acquisition and subsequent decreases to the expected cash flows will generally result in a provision for loan losses charge in the Company’s consolidated statements of operations. Any increases to the cash flow projections are recognized on a prospective basis through an increase to the pool’s accretion income over its remaining life once any previously recorded provision expense has been reversed. These cash flow evaluations are inherently subjective as they require material estimates, all of which may be susceptible to significant change. f) Loans held for sale—Loans originated and intended for sale in the secondary market are carried at the lower of aggregate cost or estimated fair value. Net unrealized losses, if any, are recognized through a valuation allowance that is recorded as a charge to income. Deferred fees and costs related to these loans are not amortized, but are recognized as part of the cost basis of the loan at the time it is sold. Gains or losses are recognized upon sale and are included as a component of gain on sale of mortgages, net in the consolidated statements of operations. Loans held for sale have primarily been fixed rate single-family residential mortgage loans under contract to be sold in the secondary market. In most cases, loans in this category are sold within 45 days. These loans are generally sold with the mortgage servicing rights released. Under limited circumstances, buyers may have recourse to return a purchased loan to the Company. Recourse conditions may include early payment default, breach of representations or warranties, or documentation deficiencies. The Company enters into commitments to originate residential mortgage loans whereby the interest rate on the loan is determined prior to funding (i.e. interest rate lock commitments). Such interest rate lock commitments on mortgage loans to be sold in the secondary market are considered to be derivatives. To protect against the price risk inherent in residential mortgage loan commitments, the Company utilizes both "best efforts" and "mandatory delivery" forward loan sale commitments to mitigate the risk of potential increases or decreases in the values of loans that would result from the change in market rates for such loans. The Company manages the interest rate risk on interest rate lock commitments by entering into forward sale contracts of mortgage backed securities. Such contracts are accounted for as derivatives and are recorded at fair value as derivative assets or liabilities. They are carried on the consolidated statements of financial condition within other assets or other liabilities and changes in fair value are recorded as a component of gain on sale of mortgages, net in the consolidated statements of operations. The gross gains on loan sales are recognized based on new loan commitments with adjustment for price and pair-off activity. Commission expenses on loans held for sale are recognized based on loans closed. g) Allowance for loan losses—The allowance for loan losses represents management’s estimate of probable credit losses inherent in loans, including acquired loans to the extent necessary, as of the balance sheet date. The determination of the ALL takes into consideration, among other matters, the estimated fair value of the underlying collateral, economic conditions, historical net loan losses, the estimated loss emergence period, estimated default rates, any declines in cash flow assumptions from acquisition, loan structures, growth factors and other elements that warrant recognition. In addition, various regulatory agencies, as an integral part of the examination process, periodically review the ALL. Such agencies may require the Company to recognize additions to the ALL or increases to adversely graded classified loans based on their judgments about information available to them at the time of their examinations. The Company uses an internal risk rating system to indicate credit quality in the loan portfolio. The risk rating system is applied to all loans and uses a series of grades, which reflect management’s assessment of the risk attributable to loans based on an analysis of the borrower’s financial condition and ability to meet contractual debt service requirements. Loans that management perceives to have acceptable risk are categorized as “Pass” loans. The “Special Mention” loans represent loans that have potential credit weaknesses that deserve management’s close attention. Special mention loans include borrowers that have potential weaknesses or unwarranted risks that, unless corrected, may threaten the borrower’s ability to meet debt requirements. However, these borrowers are still believed to have the ability to respond to and resolve the financial issues that threaten their financial situation. Loans classified as “Substandard” are inadequately protected by the current sound worth and paying capacity of the obligor or of the collateral pledged, if any. Substandard loans have a distinct possibility of loss if the deficiencies are not corrected. “Doubtful” loans are loans that management believes the collection of payments in accordance with the terms of the loan agreement is highly questionable and improbable. Loans accounted for under ASC 310-30, despite being 90 days or more past due or internally adversely classified, may be classified as performing upon and subsequent to acquisition, regardless of whether the client is contractually delinquent, if the timing and expected cash flows on such loans can be reasonably estimated and if collection of the carrying value of such loans is expected. Interest accrual is discontinued on doubtful loans and certain substandard loans that are excluded from ASC 310-30, as is more fully discussed in note 7. The Company routinely evaluates adversely risk-rated credits for impairment. Impairment, if any, is typically measured for each loan based on a thorough analysis of the most probable source of repayment, including the present value of the loan’s expected future cash flows, the loan’s estimated fair value, or the estimated fair value of the underlying collateral less costs of disposition for collateral dependent loans. General allowances are established for loans with similar characteristics. In this process, general allowance factors are based on an analysis of historical loss and recovery experience, if any, related to originated and acquired loans, as well as certain industry experience, with adjustments made for qualitative or environmental factors that are likely to cause estimated credit losses to differ from historical experience. To the extent that the data supporting such factors has limitations, management’s judgment and experience play a key role in determining the allowance estimates. Additions to the ALL are made by provisions for loan losses that are charged to operations. The allowance is decreased by charge-offs due to losses and is increased by provisions for loan losses and recoveries. When it is determined that specific loans, or portions thereof, are uncollectible, these amounts are charged off against the ALL. If repayment of the loan is collateral dependent, the fair value of the collateral, less cost to sell, is used to determine charge-off amounts. The Company maintains an ALL for loans accounted for under ASC 310-30 as a result of impairment to loan pools arising from the periodic re-measurement of these loans. Any impairment in the individual pool is generally recognized in the current period as provision for loan losses. Any improvement in the estimated cash flows, is generally not recognized immediately, but is instead reflected as an adjustment to the related loan pools yield on a prospective basis once any previously recorded impairment has been recaptured. h) Premises and equipment—With the exception of premises and equipment acquired through business combinations, which are initially measured and recorded at fair value, purchased land is stated at cost, and buildings and equipment are carried at cost, including capitalized interest when appropriate, less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful life of the asset. The Company generally assigns depreciable lives of 39 years for buildings, 7 to 15 years for building improvements, and 3 to 7 years for equipment. Leasehold improvements are amortized over the shorter of their estimated useful lives or remaining lease terms. Maintenance and repairs are charged to non-interest expense as incurred. The Company reviews premises and equipment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. An impairment loss is recognized when the sum of the undiscounted future net cash flows expected to result from the use of the asset and its eventual disposal is less than its carrying amount. In the case of a property that is subject to an operating lease that the Company no longer expects to use, a liability is recorded equal to the remaining lease rentals, adjusted for the effects of any prepaid or deferred items recognized under the lease, and reduced by estimated sublease rentals that could be reasonably obtained for the property, even if the entity does not intend to enter into a sublease. A ratable portion of the sublease allocation is then expensed until the property is subleased. Property and equipment that meet the held-for-sale criteria is recorded at the lower of its carrying amount or fair value less cost to sell and depreciation is ceased. i) Goodwill and intangible assets—Goodwill is established and recorded if the consideration given during an acquisition transaction exceeds the fair value of the net assets received. Goodwill has an indefinite useful life and is not amortized, but is evaluated annually for potential impairment, or when events or circumstances indicate a potential impairment. Such events or circumstances may include deterioration in general economic conditions, deterioration in industry or market conditions, an increased competitive environment, a decline in market-dependent multiples or metrics, declining financial performance, entity-specific events or circumstances or a sustained decrease in share price (either in absolute terms or relative to peers). The Company first evaluates potential impairment of goodwill by comparing the fair value of the reporting unit to its carrying amount. Any excess of carrying value over fair value would indicate a potential impairment and the Company would proceed to perform an additional test to determine whether goodwill has been impaired and calculate the amount of that impairment. Intangible assets that have finite useful lives, such as core deposit intangibles, are amortized over their estimated useful lives. The Company’s core deposit intangible assets represent the value of the anticipated future cost savings that will result from the acquired core deposit relationships versus an alternative source of funding. Judgment may be used in assessing goodwill and intangible assets for impairment. Estimates of fair value are based on projections of revenues, operating costs and cash flows of the reporting unit considering historical and anticipated future results, general economic and market conditions, as well as the impact of planned business or operational strategies. The valuations use a combination of present value techniques to measure fair value and consider market factors. Additionally, judgment is used in determining the useful lives of finite-lived intangible assets. Adverse changes in the economic environment, operations of the reporting unit, or changes in judgments and projections could result in a significantly different estimate of the fair value of the reporting unit and could result in an impairment of goodwill and/or intangible assets. j) Other real estate owned—OREO consists of property that has been foreclosed on or repossessed by deed in lieu of foreclosure. The assets are initially recorded at the fair value of the collateral less estimated costs to sell, with any initial valuation adjustments charged to the ALL. Subsequent downward valuation adjustments, if any, in addition to gains and losses realized on sales and net operating expenses, are recorded in other non-interest expense, while any subsequent write-ups are recorded in non-interest income. Costs associated with maintaining property, such as utilities and maintenance, are charged to expense in the period in which they occur, while costs relating to the development and improvement of property are capitalized to the extent the balance does not exceed fair value. All OREO acquired through acquisition is recorded at fair value, less cost to sell, at the date of acquisition. k) Bank-owned life insurance—The Company purchased or acquired bank-owned life insurance ("BOLI") policies on certain associates of the Company. The Company is the owner and beneficiary of these policies. The BOLI is carried at net realizable value with changes in net realizable value recorded in non-interest income. l) Securities purchased under agreements to resell and securities sold under agreements to repurchase—The Company periodically enters into purchases or sales of securities under agreements to resell or repurchase as of a specified future date. The securities purchased under agreements to resell are accounted for as collateralized financing transactions and are reflected as an asset in the consolidated statements of financial condition. The securities pledged by the counterparties are held by a third party custodian and valued daily. The Company may require additional collateral to ensure full collateralization for these transactions. The repurchase agreements are considered financing agreements and the obligation to repurchase assets sold is reflected as a liability in the consolidated statements of financial condition of the Company. The repurchase agreements are collateralized by debt securities that are under the control of the Company. m) Stock-based compensation—The Company accounts for stock-based compensation in accordance with ASC Topic 718, Compensation—Stock Compensation as amended by ASU 2016-09, Improvements to Employee Share-Based Payment Accounting. The Company grants stock-based awards including stock options, restricted stock and performance stock units. Stock option grants are for a fixed number of common shares and are issued to associates and directors at exercise prices which are not less than the fair value of a share of stock at the date of grant. The options vest over a time period stated in each option agreement and may be subject to other performance vesting conditions, which require the related compensation expense to be recorded ratably over the requisite service period starting when such conditions become probable. Restricted stock is granted for a fixed number of shares, the transferability of which is restricted until such shares become vested according to the terms in the award agreement. Restricted shares may have multiple vesting qualifications which can include time vesting of a set portion of the restricted shares, performance criterion, such as market criteria that are tied to specified market conditions of the Company’s common stock price. The fair value of stock options and market-based awards is measured using either a Black-Scholes model or a Monte Carlo simulation model, depending on the vesting requirement of each grant. The fair value of time-based restricted stock awards is based on the Company’s stock price on the date of grant. Compensation expense for the portion of the awards that contain a market vesting condition is recognized over the derived service period based on the fair value of the awards on the grant date. Compensation expense for the portion of the awards that contain performance and service vesting conditions is recognized over the requisite service period based on the fair value of the awards on the grant date. The amortization of stock-based compensation reflects any estimated forfeitures and the expense realized in subsequent periods may be adjusted to reflect the actual forfeitures realized. The outstanding stock options carry a maximum contractual term of ten years and the market vesting restricted shares carry contractual terms that range from 7-10 years, with certain awards having no defined contractual term. To the extent that any award is forfeited, surrendered, terminated, expires, or lapses without being exercised, the shares of stock subject to such award not delivered as a result thereof are again made available for awards under the Plan. In the fourth quarter of 2016, the Company early adopted ASU 2016-09, with an effective date of January 1, 2016. The ASU requires all excess tax benefits and tax deficiencies (including tax benefits of dividends on share-based payment awards) be recognized in the consolidated statements of operations as a component of income tax expense or benefit. The tax effects of exercised, expired or vested awards are treated as discrete items in the reporting period in which they occur and may result in increased volatility in our effective tax rate. As part of the adoption of this standard, the Company made an accounting election to continue to estimate forfeitures when determining amortization expense of stock-based compensation. Additionally, the Company applied the retrospective transition method for the presentation of “Net tax (benefit) deficit on stock-based compensation” from a financing activity to an operating activity in the Company’s consolidated statements of cash flows. Cash paid by the Company when directly withholding shares for tax withholding purposes is classified as a financing activity in the consolidated statements of cash flows. For the year ended December 31, 2016, the impact of adopting all provisions of the ASU to the Company’s consolidated statements of operations was a $2.1 million decrease to income tax expense from excess tax benefits realized in the fourth quarter of 2016. Prior to 2016, excess tax benefits were recognized in additional paid-in capital and tax deficiencies were recognized either as an offset to accumulated excess tax benefits, if any, or in the consolidated statements of operations. Excess tax benefits were not recognized until the deduction reduces taxes payable. Additionally, excess tax benefits from stock-based compensation was included in operating and financing activities within the Company’s consolidated statements of cash flows. n) Warrants—The Company issued warrants to certain lead investors in 2009 and 2010. The warrants are for a fixed number of shares and had original expirations of ten years from the date of issuance. If exercised, the Company must settle the warrants in its own stock. Historically, the exercise price and the number of warrants were subject to certain down-round provisions, whereby certain subsequent equity issuances at a price below the existing exercise price would result in a downward adjustment to the exercise price and an increase in the number of warrants, and as a result, the warrants were historically classified as a liability in the Company’s consolidated statements of financial condition with changes in the fair value each period reported in the statements of operations as non-interest expense. During 2015, the outstanding warrant contracts were modified, terminating the down-round provisions and extending the contractual life an additional six months from the original expiration. As a result, the warrant contracts were recorded at fair value as of the modification date using a Black-Scholes model with the change in fair value reported in the statement of operations as non-interest expense, and were reclassified to shareholders’ equity as of December 31, 2015. o) Income taxes—The Company and its subsidiaries file U.S. federal and certain state income tax returns on a consolidated basis. Additionally, the Company and its subsidiaries file separate state income tax returns with various state jurisdictions. The provision for income taxes includes the income tax balances of the Company and all of its subsidiaries. Deferred tax assets and liabilities are recognized for temporary differences between the financial reporting basis and the tax basis of the Company’s assets and liabilities at enacted tax rates expected to be in effect when such amounts are realized or settled. Deferred tax assets and liabilities are adjusted for the effects of changes in tax rates in the period of change. The Company establishes a valuation allowance when management believes, based on the weight of available evidence, it is more likely than not that some portion of the deferred tax assets will not be realized. The Company recognizes and measures income tax benefits based upon a two-step model: 1) a tax position must be more likely than not to be sustained based solely on its technical merits in order to be recognized; and 2) the benefit is measured as the largest dollar amount of that position that is more likely than not to be sustained upon settlement. The difference between the benefit recognized for a position in this model and the tax benefit claimed on a tax return is treated as an unrecognized tax benefit. The Company recognizes income tax related interest and penalties in other non-interest expense. p) Income per share—The Company applies the two-class method of computing income per share as certain of the Company's restricted shares are entitled to non-forfeitable dividends and are therefore considered to be a class of participating securities. The two-class method allocates income according to dividends declared and participation rights in undistributed income. Basic income per share is computed by dividing income allocated to common shareholders by the weighted average number of common shares outstanding during each period. Diluted income per common share is computed by dividing income allocated to common shareholders by the weighted average common shares outstanding during the period, plus amounts representing the dilutive effect of stock options outstanding, certain unvested restricted shares, warrants to issue common stock, or other contracts to issue common shares (“common stock equivalents”) using the treasury stock method. Common stock equivalents are excluded from the computation of diluted earnings per common share in periods in which they have an anti-dilutive effect. q) Interest Rate Swap Derivatives—The Company carries all derivatives on the statement of financial condition at fair value. All derivative instruments are recognized as either assets or liabilities depending on the rights or obligations under the contracts. All gains and losses on the derivatives due to changes in fair value are recognized in earnings each period. The Company offers interest rate swap products to certain of its clients to manage potential changes in interest rates. Each contract between the Company and a client is offset with a contract between the Company and an institutional counterparty, thus minimizing the Company's exposure to rate changes. The Company's portfolio consists of a “matched book,” and as such, changes in fair value of the swap pairs will largely offset in earnings. In accordance with applicable accounting guidance, if certain conditions are met, a derivative may be designated as (1) a hedge of the exposure to changes in the fair value of a recognized asset or liability, or of an unrecognized firm commitment, that are attributable to a particular risk (referred to as a fair value hedge) or (2) a hedge of the exposure to variability in the cash flows of a recognized asset or liability, or of a forecasted transaction, that is attributable to a particular risk (referred to as a cash flow hedge). The Company documents all hedging relationships at the inception of each hedging relationship and uses industry accepted methodologies and ranges to determine the effectiveness of each hedge. The fair value of the hedged item is calculated using the estimated future cash flows of the hedged item and applying discount rates equal to the market interest rate for the hedged item at the inception of the hedging relationship (inception benchmark interest rate plus an inception credit spread), adjusted for changes in the designated benchmark interest rate thereafter. r) Treasury stock —When the Company acquires treasury stock, the sum of the consideration paid and direct transaction costs after tax is recognized as a deduction from equity. The cost basis for the reissuance of treasury stock is determined using a first-in, first-out basis. To the extent that the reissuance price is more than the cost basis (gain), the excess is recorded as an increase to additional paid-in capital in the consolidated statements of financial condition. If the reissuance price is less than the cost basis (loss), the difference is recorded to additional paid-in capital to the extent there is a cumulative treasury stock paid-in capital balance. Any loss in excess of the cumulative treasury stock paid-in capital balance is charged to retained earnings.

Note 2 Summary of Significant Accounting Policies

a) Acquisition activities—The Company accounts for business combinations under the acquisition method of accounting. Assets acquired and liabilities assumed are measured and recorded at fair value at the date of acquisition, including identifiable intangible assets. If the fair value of net assets acquired exceeds the fair value of consideration paid, a bargain purchase gain is recognized at the date of acquisition. Conversely, if the consideration paid exceeds the fair value of the net assets acquired, goodwill is recognized at the acquisition date. Fair values are subject to refinement for up to a maximum of one year after the closing date of an acquisition as information relative to closing date fair values becomes available. Adjustments recorded to the acquired assets and liabilities assumed are applied prospectively in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Update (“ASU”) 2015-16, Simplifying the Accounting for Measurement-Period Adjustments. The determination of the fair value of loans acquired takes into account credit quality deterioration and probability of loss therefore, the related ALL is not carried forward at the time of acquisition.

Identifiable intangible assets are recognized separately if they arise from contractual or other legal rights or if they are separable (i.e., capable of being sold, transferred, licensed, rented, or exchanged separately from the entity). Deposit liabilities and the related depositor relationship intangible assets, known as the core deposit intangible assets, may be exchanged in observable exchange transactions. As a result, the core deposit intangible asset is considered identifiable, because the separability criterion has been met.

b) Cash and cash equivalents—Cash and cash equivalents include cash, cash items, amounts due from other banks, amounts due from the Federal Reserve Bank of Kansas City, federal funds sold, and interest-bearing bank deposits.

c) Investment securities—Investment securities may be classified in three categories: trading, available-for-sale and held-to-maturity. Management determines the appropriate classification at the time of purchase and reevaluates the classification at each reporting period. Any sales of available-for-sale securities are for the purpose of executing the Company’s asset/liability management strategy, reducing borrowings, funding loan growth, providing liquidity, or eliminating a perceived credit risk in a specific security. Held-to-maturity securities are carried at amortized cost and the available-for-sale securities are carried at estimated fair value. Unrealized gains or losses on securities available-for-sale are reported as accumulated other comprehensive income (loss) (“AOCI”), a component of shareholders’ equity, net of income tax. Gains and losses realized upon sales of securities are calculated using the specific identification method. Premiums and discounts are amortized to interest income over the estimated lives of the securities. Prepayment experience is periodically evaluated and a determination made regarding the appropriate estimate of the future rates of prepayment. When a change in a bond’s estimated remaining life is necessary, a corresponding adjustment is made in the related premium amortization or discount accretion. Purchases and sales of securities, including any corresponding gains or losses, are recognized on a trade-date basis and a receivable or payable is recognized for pending transaction settlements.

Management evaluates all investments for OTTI on a quarterly basis, and more frequently when economic or market conditions warrant such evaluation. Impairment is considered to be other-than-temporary if it is likely that all amounts contractually due will not be received for debt securities and when there is no positive evidence indicating that an investment’s carrying amount is recoverable in the near term for equity securities. When impairment is considered other-than-temporary, the cost basis of the security is written down to fair value, with the impairment charge related to credit included in earnings, while the impairment charge related to all other factors is recognized in OCI. If the Company has the intent to sell the security or it is more likely than not that the Company will be required to sell the security, the entire amount of the OTTI is recorded in earnings. In evaluating whether the impairment is temporary or other than temporary, the Company considers, among other things, the severity and duration of the unrealized loss position; adverse conditions specifically related to the security; changes in expected future cash flows; downgrades in the rating of the security by a rating agency; the failure of the issuer to make scheduled interest or principal payments; whether the Company has the intent to sell the security; and whether it is more likely than not that the Company will be required to sell the security.

d) Non-marketable securities—Non-marketable securities include Federal Reserve Bank ("FRB") stock, Federal Home Loan Bank ("FHLB") stock and non-negotiable certificates of deposit acquired in the acquisition of Pine River Bank Corporation, the parent company of Pine River Valley Bank (“Pine River”). These securities have been acquired for debt facility or regulatory purposes and are carried at cost.

e) Loans receivable—Loans receivable include loans originated by the Company and loans that are acquired through acquisitions. Loans originated by the Company are carried at the principal amount outstanding, net of premiums, discounts, unearned income, and deferred loan fees and costs. Loan fees and certain costs of originating loans are deferred and the net amount is amortized over the contractual life of the related loans. Acquired loans are initially recorded at fair value and are accounted for under either Accounting Standards Codification (“ASC”) 310-30, Loans and Debt Securities Acquired with Deteriorated Credit Quality (see additional information below) or ASC Topic 310, Receivables. Non-refundable loan origination and commitment fees, net of direct costs of originating or acquiring loans, and fair value adjustments for acquired loans, are deferred and recognized over the remaining lives of the related loans in accordance with ASC 310-20.

Acquired loans are recorded at their estimated fair value at the time of acquisition and accounted for under either ASC 310-30 or ASC 310. Estimated fair values of acquired loans are based on a discounted cash flow methodology that considers various factors including the type of loan and related collateral, the expected timing of cash flows, classification status, fixed or variable interest rate, term of loan and whether or not the loan is amortizing, and a discount rate reflecting the Company’s assessment of risk inherent in the cash flow estimates. Acquired 310-30 loans are grouped together according to similar characteristics such as type of loan, loan purpose, geography, risk rating and underlying collateral and are treated as distinct pools when applying various valuation techniques and, in certain circumstances, for the ongoing monitoring of the credit quality and performance of the pools. Each pool is accounted for as a single loan for which the integrity is maintained throughout the life of the asset. Discounts created when the loans are recorded at their estimated fair values at acquisition are accreted over the remaining term of the loan as an adjustment to the related loan’s yield. Similar to originated loans described below, the accrual of interest income on acquired loans that are not accounted for under ASC 310-30 is discontinued when the collection of principal or interest, in whole or in part, is doubtful.

Interest income on acquired loans that are accounted for under ASC Topic 310 and interest income on loans originated by the Company is accrued and credited to income as it is earned using the interest method based on daily balances of the principal amount outstanding. However, interest is generally not accrued on loans 90 days or more past due, unless they are well secured and in the process of collection. Additionally, in certain situations, loans that are not contractually past due may be placed on non-accrual status due to the continued failure to adhere to contractual payment terms by the borrower coupled with other pertinent factors, such as insufficient collateral value or deficient primary and secondary sources of repayment. Accrued interest receivable is reversed when a loan is placed on non-accrual status and payments received generally reduce the carrying value of the loan. Interest is not accrued while a loan is on non-accrual status and interest income is generally recognized on a cash basis only after payment in full of the past due principal and collection of principal outstanding is reasonably assured. A loan may be placed back on accrual status if all contractual payments have been received, or sooner under certain conditions and collection of future principal and interest payments is no longer doubtful.

In the event of borrower default, the Company may seek recovery in compliance with state lending laws, the respective loan agreements, and credit monitoring and remediation procedures that may include modifying or restructuring a loan from its original terms, for economic or legal reasons, to provide a concession to the borrower from their original terms due to borrower financial difficulties in order to facilitate repayment. Such restructured loans are considered “troubled debt restructurings” and are identified in accordance with ASC 310-40, Troubled Debt Restructurings by Creditors. Under this guidance, modifications to loans that fall within the scope of ASC 310-30 are not considered troubled debt restructurings, regardless of otherwise meeting the definition of a troubled debt restructuring.

Loans receivable accounted for under ASC 310-30

The Company accounts for and evaluates acquired loans in accordance with the provisions of ASC 310-30, Loans and Debt Securities Acquired with Deteriorated Credit Quality. When loans exhibit evidence of credit deterioration since origination and it is probable at the date of acquisition that the Company will not collect all principal and interest payments in accordance with the terms of the loan agreement, the expected shortfall in future cash flows, as compared to the contractual amount due, is recognized as a non-accretable difference. Any excess of expected cash flows over the acquisition date fair value is known as the accretable yield, and is recognized as accretion income over the life of each pool. Contractual fees not expected to be collected are not included in ASC 310-30 contractual cash flows. Should fees be subsequently collected, the cash flows are accounted for as non 310-30 fee income in the period they are received. Loans that are accounted for under ASC 310-30 that meet the criteria for non-accrual of interest at the time of acquisition or subsequent to acquisition, may be considered performing, regardless of whether the client is contractually delinquent, if the timing and expected cash flows on such loans can be reasonably estimated and if collection of the new carrying value of such loans is expected.

The expected cash flows of loans accounted for under ASC 310-30 are periodically remeasured utilizing the same cash flow methodology used at the time of acquisition and subsequent decreases to the expected cash flows will generally result in a provision for loan losses charge in the Company’s consolidated statements of operations. Any increases to the cash flow projections are recognized on a prospective basis through an increase to the pool’s accretion income over its remaining life once any previously recorded provision expense has been reversed. These cash flow evaluations are inherently subjective as they require material estimates, all of which may be susceptible to significant change.

f) Loans held for sale—Loans originated and intended for sale in the secondary market are carried at the lower of aggregate cost or estimated fair value. Net unrealized losses, if any, are recognized through a valuation allowance that is recorded as a charge to income. Deferred fees and costs related to these loans are not amortized, but are recognized as part of the cost basis of the loan at the time it is sold. Gains or losses are recognized upon sale and are included as a component of gain on sale of mortgages, net in the consolidated statements of operations. Loans held for sale have primarily been fixed rate single-family residential mortgage loans under contract to be sold in the secondary market. In most cases, loans in this category are sold within 45 days. These loans are generally sold with the mortgage servicing rights released. Under limited circumstances, buyers may have recourse to return a purchased loan to the Company. Recourse conditions may include early payment default, breach of representations or warranties, or documentation deficiencies.

The Company enters into commitments to originate residential mortgage loans whereby the interest rate on the loan is determined prior to funding (i.e. interest rate lock commitments). Such interest rate lock commitments on mortgage loans to be sold in the secondary market are considered to be derivatives. To protect against the price risk inherent in residential mortgage loan commitments, the Company utilizes both "best efforts" and "mandatory delivery" forward loan sale commitments to mitigate the risk of potential increases or decreases in the values of loans that would result from the change in market rates for such loans. The Company manages the interest rate risk on interest rate lock commitments by entering into forward sale contracts of mortgage backed securities. Such contracts are accounted for as derivatives and are recorded at fair value as derivative assets or liabilities. They are carried on the consolidated statements of financial condition within other assets or other liabilities and changes in fair value are recorded as a component of gain on sale of mortgages, net in the consolidated statements of operations. The gross gains on loan sales are recognized based on new loan commitments with adjustment for price and pair-off activity. Commission expenses on loans held for sale are recognized based on loans closed.

g) Allowance for loan losses—The allowance for loan losses represents management’s estimate of probable credit losses inherent in loans, including acquired loans to the extent necessary, as of the balance sheet date. The determination of the ALL takes into consideration, among other matters, the estimated fair value of the underlying collateral, economic conditions, historical net loan losses, the estimated loss emergence period, estimated default rates, any declines in cash flow assumptions from acquisition, loan structures, growth factors and other elements that warrant recognition. In addition, various regulatory agencies, as an integral part of the examination process, periodically review the ALL. Such agencies may require the Company to recognize additions to the ALL or increases to adversely graded classified loans based on their judgments about information available to them at the time of their examinations.

The Company uses an internal risk rating system to indicate credit quality in the loan portfolio. The risk rating system is applied to all loans and uses a series of grades, which reflect management’s assessment of the risk attributable to loans based on an analysis of the borrower’s financial condition and ability to meet contractual debt service requirements. Loans that management perceives to have acceptable risk are categorized as “Pass” loans. The “Special Mention” loans represent loans that have potential credit weaknesses that deserve management’s close attention. Special mention loans include borrowers that have potential weaknesses or unwarranted risks that, unless corrected, may threaten the borrower’s ability to meet debt requirements. However, these borrowers are still believed to have the ability to respond to and resolve the financial issues that threaten their financial situation. Loans classified as “Substandard” are inadequately protected by the current sound worth and paying capacity of the obligor or of the collateral pledged, if any. Substandard loans have a distinct possibility of loss if the deficiencies are not corrected. “Doubtful” loans are loans that management believes the collection of payments in accordance with the terms of the loan agreement is highly questionable and improbable. Loans accounted for under ASC 310-30, despite being 90 days or more past due or internally adversely classified, may be classified as performing upon and subsequent to acquisition, regardless of whether the client is contractually delinquent, if the timing and expected cash flows on such loans can be reasonably estimated and if collection of the carrying value of such loans is expected. Interest accrual is discontinued on doubtful loans and certain substandard loans that are excluded from ASC 310-30, as is more fully discussed in note 7.

The Company routinely evaluates adversely risk-rated credits for impairment. Impairment, if any, is typically measured for each loan based on a thorough analysis of the most probable source of repayment, including the present value of the loan’s expected future cash flows, the loan’s estimated fair value, or the estimated fair value of the underlying collateral less costs of disposition for collateral dependent loans. General allowances are established for loans with similar characteristics. In this process, general allowance factors are based on an analysis of historical loss and recovery experience, if any, related to originated and acquired loans, as well as certain industry experience, with adjustments made for qualitative or environmental factors that are likely to cause estimated credit losses to differ from historical experience. To the extent that the data supporting such factors has limitations, management’s judgment and experience play a key role in determining the allowance estimates.

Additions to the ALL are made by provisions for loan losses that are charged to operations. The allowance is decreased by charge-offs due to losses and is increased by provisions for loan losses and recoveries. When it is determined that specific loans, or portions thereof, are uncollectible, these amounts are charged off against the ALL. If repayment of the loan is collateral dependent, the fair value of the collateral, less cost to sell, is used to determine charge-off amounts.

The Company maintains an ALL for loans accounted for under ASC 310-30 as a result of impairment to loan pools arising from the periodic re-measurement of these loans. Any impairment in the individual pool is generally recognized in the current period as provision for loan losses. Any improvement in the estimated cash flows, is generally not recognized immediately, but is instead reflected as an adjustment to the related loan pools yield on a prospective basis once any previously recorded impairment has been recaptured.

h) Premises and equipment—With the exception of premises and equipment acquired through business combinations, which are initially measured and recorded at fair value, purchased land is stated at cost, and buildings and equipment are carried at cost, including capitalized interest when appropriate, less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful life of the asset. The Company generally assigns depreciable lives of 39 years for buildings, 7 to 15 years for building improvements, and 3 to 7 years for equipment. Leasehold improvements are amortized over the shorter of their estimated useful lives or remaining lease terms. Maintenance and repairs are charged to non-interest expense as incurred. The Company reviews premises and equipment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. An impairment loss is recognized when the sum of the undiscounted future net cash flows expected to result from the use of the asset and its eventual disposal is less than its carrying amount. In the case of a property that is subject to an operating lease that the Company no longer expects to use, a liability is recorded equal to the remaining lease rentals, adjusted for the effects of any prepaid or deferred items recognized under the lease, and reduced by estimated sublease rentals that could be reasonably obtained for the property, even if the entity does not intend to enter into a sublease. A ratable portion of the sublease allocation is then expensed until the property is subleased. Property and equipment that meet the held-for-sale criteria is recorded at the lower of its carrying amount or fair value less cost to sell and depreciation is ceased.

i) Goodwill and intangible assets—Goodwill is established and recorded if the consideration given during an acquisition transaction exceeds the fair value of the net assets received. Goodwill has an indefinite useful life and is not amortized, but is evaluated annually for potential impairment, or when events or circumstances indicate a potential impairment. Such events or circumstances may include deterioration in general economic conditions, deterioration in industry or market conditions, an increased competitive environment, a decline in market-dependent multiples or metrics, declining financial performance, entity-specific events or circumstances or a sustained decrease in share price (either in absolute terms or relative to peers). The Company first evaluates potential impairment of goodwill by comparing the fair value of the reporting unit to its carrying amount. Any excess of carrying value over fair value would indicate a potential impairment and the Company would proceed to perform an additional test to determine whether goodwill has been impaired and calculate the amount of that impairment. Intangible assets that have finite useful lives, such as core deposit intangibles, are amortized over their estimated useful lives. The Company’s core deposit intangible assets represent the value of the anticipated future cost savings that will result from the acquired core deposit relationships versus an alternative source of funding.

Judgment may be used in assessing goodwill and intangible assets for impairment. Estimates of fair value are based on projections of revenues, operating costs and cash flows of the reporting unit considering historical and anticipated future results, general economic and market conditions, as well as the impact of planned business or operational strategies. The valuations use a combination of present value techniques to measure fair value and consider market factors. Additionally, judgment is used in determining the useful lives of finite-lived intangible assets. Adverse changes in the economic environment, operations of the reporting unit, or changes in judgments and projections could result in a significantly different estimate of the fair value of the reporting unit and could result in an impairment of goodwill and/or intangible assets.

j) Other real estate owned—OREO consists of property that has been foreclosed on or repossessed by deed in lieu of foreclosure. The assets are initially recorded at the fair value of the collateral less estimated costs to sell, with any initial valuation adjustments charged to the ALL. Subsequent downward valuation adjustments, if any, in addition to gains and losses realized on sales and net operating expenses, are recorded in other non-interest expense, while any subsequent write-ups are recorded in non-interest income. Costs associated with maintaining property, such as utilities and maintenance, are charged to expense in the period in which they occur, while costs relating to the development and improvement of property are capitalized to the extent the balance does not exceed fair value. All OREO acquired through acquisition is recorded at fair value, less cost to sell, at the date of acquisition.

k) Bank-owned life insurance—The Company purchased or acquired bank-owned life insurance ("BOLI") policies on certain associates of the Company. The Company is the owner and beneficiary of these policies. The BOLI is carried at net realizable value with changes in net realizable value recorded in non-interest income.

l) Securities purchased under agreements to resell and securities sold under agreements to repurchase—The Company periodically enters into purchases or sales of securities under agreements to resell or repurchase as of a specified future date. The securities purchased under agreements to resell are accounted for as collateralized financing transactions and are reflected as an asset in the consolidated statements of financial condition. The securities pledged by the counterparties are held by a third party custodian and valued daily. The Company may require additional collateral to ensure full collateralization for these transactions. The repurchase agreements are considered financing agreements and the obligation to repurchase assets sold is reflected as a liability in the consolidated statements of financial condition of the Company. The repurchase agreements are collateralized by debt securities that are under the control of the Company.

m) Stock-based compensation—The Company accounts for stock-based compensation in accordance with ASC Topic

718, Compensation—Stock Compensation as amended by ASU 2016-09, Improvements to Employee Share-Based Payment Accounting. The Company grants stock-based awards including stock options, restricted stock and performance stock units. Stock option grants are for a fixed number of common shares and are issued to associates and directors at exercise prices which are not less than the fair value of a share of stock at the date of grant. The options vest over a time period stated in each option agreement and may be subject to other performance vesting conditions, which require the related compensation expense to be recorded ratably over the requisite service period starting when such conditions become probable. Restricted stock is granted for a fixed number of shares, the transferability of which is restricted until such shares become vested according to the terms in the award agreement. Restricted shares may have multiple vesting qualifications which can include time vesting of a set portion of the restricted shares, performance criterion, such as market criteria that are tied to specified market conditions of the Company’s common stock price.

The fair value of stock options and market-based awards is measured using either a Black-Scholes model or a Monte Carlo simulation model, depending on the vesting requirement of each grant. The fair value of time-based restricted stock awards is based on the Company’s stock price on the date of grant. Compensation expense for the portion of the awards that contain a market vesting condition is recognized over the derived service period based on the fair value of the awards on the grant date. Compensation expense for the portion of the awards that contain performance and service vesting conditions is recognized over the requisite service period based on the fair value of the awards on the grant date. The amortization of stock-based compensation reflects any estimated forfeitures and the expense realized in subsequent periods may be adjusted to reflect the actual forfeitures realized. The outstanding stock options carry a maximum contractual term of ten years and the market vesting restricted shares carry contractual terms that range from 7-10 years, with certain awards having no defined contractual term. To the extent that any award is forfeited, surrendered, terminated, expires, or lapses without being exercised, the shares of stock subject to such award not delivered as a result thereof are again made available for awards under the Plan.

In the fourth quarter of 2016, the Company early adopted ASU 2016-09, with an effective date of January 1, 2016. The ASU requires all excess tax benefits and tax deficiencies (including tax benefits of dividends on share-based payment awards) be recognized in the consolidated statements of operations as a component of income tax expense or benefit. The tax effects of exercised, expired or vested awards are treated as discrete items in the reporting period in which they occur and may result in increased volatility in our effective tax rate. As part of the adoption of this standard, the Company made an accounting election to continue to estimate forfeitures when determining amortization expense of stock-based compensation. Additionally, the Company applied the retrospective transition method for the presentation of “Net tax (benefit) deficit on stock-based compensation” from a financing activity to an operating activity in the Company’s consolidated statements of cash flows. Cash paid by the Company when directly withholding shares for tax withholding purposes is classified as a financing activity in the consolidated statements of cash flows. For the year ended December 31, 2016, the impact of adopting all provisions of the ASU to the Company’s consolidated statements of operations was a $2.1 million decrease to income tax expense from excess tax benefits realized in the fourth quarter of 2016.

Prior to 2016, excess tax benefits were recognized in additional paid-in capital and tax deficiencies were recognized either as an offset to accumulated excess tax benefits, if any, or in the consolidated statements of operations. Excess tax benefits were not recognized until the deduction reduces taxes payable. Additionally, excess tax benefits from stock-based compensation was included in operating and financing activities within the Company’s consolidated statements of cash flows.

n) Warrants—The Company issued warrants to certain lead investors in 2009 and 2010. The warrants are for a fixed number of shares and had original expirations of ten years from the date of issuance. If exercised, the Company must settle the warrants in its own stock. Historically, the exercise price and the number of warrants were subject to certain down-round provisions, whereby certain subsequent equity issuances at a price below the existing exercise price would result in a downward adjustment to the exercise price and an increase in the number of warrants, and as a result, the warrants were historically classified as a liability in the Company’s consolidated statements of financial condition with changes in the fair value each period reported in the statements of operations as non-interest expense. During 2015, the outstanding warrant contracts were modified, terminating the down-round provisions and extending the contractual life an additional six months from the original expiration. As a result, the warrant contracts were recorded at fair value as of the modification date using a Black-Scholes model with the change in fair value reported in the statement of operations as non-interest expense, and were reclassified to shareholders’ equity as of December 31, 2015.

o) Income taxes—The Company and its subsidiaries file U.S. federal and certain state income tax returns on a consolidated basis. Additionally, the Company and its subsidiaries file separate state income tax returns with various state jurisdictions. The provision for income taxes includes the income tax balances of the Company and all of its subsidiaries.

Deferred tax assets and liabilities are recognized for temporary differences between the financial reporting basis and the tax basis of the Company’s assets and liabilities at enacted tax rates expected to be in effect when such amounts are realized or settled. Deferred tax assets and liabilities are adjusted for the effects of changes in tax rates in the period of change. The Company establishes a valuation allowance when management believes, based on the weight of available evidence, it is more likely than not that some portion of the deferred tax assets will not be realized.

The Company recognizes and measures income tax benefits based upon a two-step model: 1) a tax position must be more likely than not to be sustained based solely on its technical merits in order to be recognized; and 2) the benefit is measured as the largest dollar amount of that position that is more likely than not to be sustained upon settlement. The difference between the benefit recognized for a position in this model and the tax benefit claimed on a tax return is treated as an unrecognized tax benefit. The Company recognizes income tax related interest and penalties in other non-interest expense.

p) Income per share—The Company applies the two-class method of computing income per share as certain of the Company's restricted shares are entitled to non-forfeitable dividends and are therefore considered to be a class of participating securities. The two-class method allocates income according to dividends declared and participation rights in undistributed income. Basic income per share is computed by dividing income allocated to common shareholders by the weighted average number of common shares outstanding during each period. Diluted income per common share is computed by dividing income allocated to common shareholders by the weighted average common shares outstanding during the period, plus amounts representing the dilutive effect of stock options outstanding, certain unvested restricted shares, warrants to issue common stock, or other contracts to issue common shares (“common stock equivalents”) using the treasury stock method. Common stock equivalents are excluded from the computation of diluted earnings per common share in periods in which they have an anti-dilutive effect.

q) Interest Rate Swap Derivatives—The Company carries all derivatives on the statement of financial condition at fair value. All derivative instruments are recognized as either assets or liabilities depending on the rights or obligations under the contracts. All gains and losses on the derivatives due to changes in fair value are recognized in earnings each period.

The Company offers interest rate swap products to certain of its clients to manage potential changes in interest rates. Each contract between the Company and a client is offset with a contract between the Company and an institutional counterparty, thus minimizing the Company's exposure to rate changes. The Company's portfolio consists of a “matched book,” and as such, changes in fair value of the swap pairs will largely offset in earnings. In accordance with applicable accounting guidance, if certain conditions are met, a derivative may be designated as (1) a hedge of the exposure to changes in the fair value of a recognized asset or liability, or of an unrecognized firm commitment, that are attributable to a particular risk (referred to as a fair value hedge) or (2) a hedge of the exposure to variability in the cash flows of a recognized asset or liability, or of a forecasted transaction, that is attributable to a particular risk (referred to as a cash flow hedge). The Company documents all hedging relationships at the inception of each hedging relationship and uses industry accepted methodologies and ranges to determine the effectiveness of each hedge. The fair value of the hedged item is calculated using the estimated future cash flows of the hedged item and applying discount rates equal to the market interest rate for the hedged item at the inception of the hedging relationship (inception benchmark interest rate plus an inception credit spread), adjusted for changes in the designated benchmark interest rate thereafter.

r) Treasury stock —When the Company acquires treasury stock, the sum of the consideration paid and direct transaction costs after tax is recognized as a deduction from equity. The cost basis for the reissuance of treasury stock is determined using a first-in, first-out basis. To the extent that the reissuance price is more than the cost basis (gain), the excess is recorded as an increase to additional paid-in capital in the consolidated statements of financial condition. If the reissuance price is less than the cost basis (loss), the difference is recorded to additional paid-in capital to the extent there is a cumulative treasury stock paid-in capital balance. Any loss in excess of the cumulative treasury stock paid-in capital balance is charged to retained earnings.
