Basis of Presentation
Basis of Presentation	Note 1 Basis of Presenta tion ​ National Bank Holdings Corporation is a bank holding company that was incorporated in the State of Delaware in 2009. The Company is headquartered in Greenwood Village, Colorado, and its primary operations are conducted through its wholly owned subsidiary, NBH Bank, a Colorado state-chartered bank and a member of the Federal Reserve System. The Company provides a variety of banking products to both commercial and consumer clients through a network of 81 banking centers as of December 31, 2021, located primarily in Colorado, the greater Kansas City region, Texas, Utah and New Mexico, as well as through online and mobile banking products and services. ​ The accompanying consolidated financial statements include the accounts of the Company and its wholly owned subsidiary, NBH Bank. The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) and, where applicable, with general practices in the banking industry or guidelines prescribed by bank regulatory agencies. The consolidated financial statements reflect all adjustments which are, in the opinion of management, necessary for a fair statement of the results presented. All such adjustments are of a normal recurring nature. All significant intercompany balances and transactions have been eliminated in consolidation. Certain reclassifications of prior years' amounts are made whenever necessary to conform to current period presentation. During 2021, the Company updated its asset classifications to include certain financial instruments within non-marketable securities that were previously reported in other assets in the statements of financial condition. The prior period presentations have been reclassified to conform to the current period presentations. Refer to note 5 for further discussion. All amounts are in thousands, except share data and per share data, or as otherwise noted. ​ While general economic conditions have been improving, the COVID-19 pandemic caused disruption to the communities we serve and has changed the way we live and work. We continue to remain committed to ensuring our associates, clients and communities are receiving the support they need through our banking centers and our digital banking platform. Our teams have been working diligently to support our clients who are experiencing financial hardship due to COVID-19 through participation in the SBA’s Paycheck Protection Program, including assistance with PPP loan forgiveness applications, and loan modifications, as needed. While access to vaccines in the United States has increased, the efficacy of those vaccines, the impact of emerging targeted vaccine mandates and new variants of the virus, and the length of time that the government-mandated measures must remain in place or potentially be reinstituted to address COVID-19 are unknown. The pandemic has had a negative impact to the U.S. labor market, consumer spending and business operations, and it is not clear how long new outbreaks of COVID-19 cases will have a continued impact. ​ GAAP requires management to make estimates that affect the reported amounts of assets, liabilities, revenues and expenses and disclosures of contingent assets and liabilities. By their nature, estimates are based on judgment and available information. Management has made significant estimates in certain areas, such as the fair values of financial instruments, contingent liabilities and the allowance for credit losses (“ACL”). Because of the inherent uncertainties associated with any estimation process and future changes in market and economic conditions, it is possible that actual results could differ significantly from those estimates.

Summary of Significant Accounting Policies
Summary of Significant Accounting Policies	Note 2 Summary of Significant Accounting Policies ​ a) Cash and cash equivalents ​ b) Investment securities ​ Management evaluates all investments in an unrealized loss position on a quarterly basis, and more frequently when economic or market conditions warrant such evaluation. 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 security is written down to fair value and the entire loss is recorded in earnings. If either of the above criteria is not met, we evaluate whether the decline in fair value is the result of credit losses or other factors. In making the assessment, we may consider various factors including the extent to which fair value is less than amortized cost, performance on any underlying collateral, downgrades in the ratings of the security by a rating agency, the failure of the issuer to make scheduled interest or principal payments and adverse conditions specifically related to the security. If the assessment indicates that a credit loss exists, the present value of cash flows expected to be collected are compared to the amortized cost basis of the security and any excess is recorded as an allowance for credit loss. When the loss is not considered a result of credit loss, the cost basis of the security is written down to fair value, with the loss charge recognized in AOCI. The Company does not measure expected credit losses for U.S. agency-backed held-to-maturity securities, since the risk of nonpayment of the amortized cost basis is zero. Credit losses are not estimated for AIR from investment securities as interest deemed uncollectible is written off through interest income. ​ Prior to the adoption of ASU 2016-13, declines in the fair value of held-to-maturity and available-for-sale securities below their cost that were deemed to be other-than-temporarily impaired were reflected in earnings as realized losses. In estimating other-than-temporary-impairment prior to January 1, 2020, the Company considered, 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 had the intent to sell the security; and whether it was more likely than not that the Company would be required to sell the security. ​ c) Non-marketable securities ​ d) Loans receivable — ​ 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. 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 is discontinued when the collection of principal or interest, in whole or in part, is doubtful. ​ Interest income on acquired loans 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. ​ The CARES Act afforded financial institutions the option to modify loans within certain parameters in response to the COVID-19 pandemic without requiring the modifications to be classified as TDRs if the borrower has been adversely impacted by COVID-19 and was current on their loan payments. The Company has modified loans due to the effects of the COVID-19 pandemic that were not classified as TDRs. Modifications include deferral of principal as well as full-payment deferral for a period ranging from three months to one year. ​ e) Loans held for sale — ​ 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 in the consolidated statements of financial condition within other assets or other liabilities, and changes in fair value are recorded net as a component of mortgage banking income 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. ​ f) Allowance for credit losses Measurement of Credit Losses on Financial Instruments ​ The ACL represents management’s estimate of lifetime credit losses inherent in loans as of the balance sheet date. The Company measures expected credit losses for loans on a pooled basis when similar risk characteristics exist. The Company has identified four primary loan segments that are further stratified into 11 loan classes to provide more granularity in analyzing loss history based upon specific loss drivers and risk factors affecting each loan class. Generally, the underlying risk of loss for each of these loan classes will follow certain norms/trends in various economic environments. Loans that do not share risk characteristics are evaluated on an individual basis and are not included in the collective evaluation. Those loans include loans on non-accrual status, loans in bankruptcy, and TDRs described below. If a specific allowance is warranted based on the borrower’s overall financial condition, the specific allowance is calculated based on discounted expected cash flows using the loan’s initial contractual effective interest rate or the fair value of the collateral less selling costs for collateral-dependent loans. ​ The Company utilizes a DCF model developed within a third-party software tool to establish expected lifetime credit losses for the loan portfolio. The ACL is calculated as the difference between the amortized cost basis and the projections from the DCF analysis. The DCF model allows for individual life of loan cash flow modeling, excluding extensions and renewals, using loan-specific interest rates and repayment schedules adjusted for estimated prepayment rates and loss recovery timing delays. The model incorporates forecasts of certain national macroeconomic factors, including unemployment rates, HPI, retail sales and GDP, which drive correlated probability of default (“PD”) and loss given default (“LGD”) rates. PD and LGD, in turn, drive the losses predicted in establishing our ACL. PD and LGD rates along with prepayment rates and loss recovery time delays are determined at a loan class level making use of both internal and peer historical loss rate data. The determination and application of the ACL accounting policy involves judgments, estimates, and uncertainties that are subject to change. For periods beyond the reasonable and supportable forecast period, we revert to historical long-term average loss rates on a straight-line basis. The length of the forecast period spans four quarters. The length of the reversion period is based on management’s assessment of the length and pattern of the current economic cycle and typically ranges from four to eight quarters. ​ Management accounts for the inherent uncertainty of the underlying economic forecast by reviewing and weighting alternate forecast scenarios. Additionally, the ACL calculation includes subjective adjustments for qualitative risk factors that are likely to cause estimated credit losses to differ from historical experience. These qualitative adjustments may increase or reduce reserve levels and include adjustments for lending management experience and risk tolerance, loan review and audit results, asset quality and portfolio trends, loan portfolio growth and industry concentrations. The Company has elected to exclude AIR from the allowance for credit losses calculation. When a loan is placed on non-accrual, any recorded AIR is reversed against interest income. ​ The determination and application of the ACL accounting policy involves judgments, estimates, and uncertainties that are subject to change. Changes in these assumptions, estimates or the conditions surrounding them may have a material impact on our financial condition, liquidity or results of operations. Various regulatory agencies, as an integral part of the examination process, periodically review the ACL. Such agencies may require the Company to recognize additions to the ACL or reserve increases to adversely graded classified loans based on their judgments about information available to them at the time of their examinations. ​ The ACL is decreased by net charge-offs and is increased by provisions for loan losses that are charged to the statements of operations. Charge-offs, if any, are typically measured for each loan based on a thorough analysis of the most probable source of repayment, such as 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. When it is determined that specific loans, or portions thereof, are uncollectible, these amounts are charged off against the ACL. ​ 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. Credit quality indicators are reviewed and updated in accordance with internal policy based on loan balance and risk rating. Interest accrual is discontinued on doubtful loans and certain substandard loans. ​ Unfunded loan commitments ​ In addition to the ACL for funded loans, the Company maintains reserves to cover the risk of loss associated with off-balance sheet unfunded loan commitments. The allowance for off-balance sheet credit losses is maintained within the other liabilities in the statements of financial condition. Under the CECL framework, adjustments to this liability are recorded as provision for credit losses in the statements of operations. Unfunded loan commitment balances are evaluated by loan class and further segregated by revolving and non-revolving commitments. In order to establish the required level of reserve, the Company applies average historical utilization rates and ACL loan model loss rates for each loan class to the outstanding unfunded commitment balances. ​ Prior to the adoption of ASU 2016-13, the Company’s determination of the allowance took 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 acquisitions, loan structures, growth factors and other elements that warrant recognition. ​ Under the prior incurred loss methodology, the Company routinely evaluated adversely risk-rated credits for impairment. Impairment, if any, was 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 were established for loans with similar characteristics. In this process, general allowance factors were 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 were likely to cause estimated credit losses to differ from historical experience. To the extent that the data supporting such factors had limitations, management’s judgment and experience played a key role in determining the allowance estimates. ​ g) Premises and equipment 7 3 ​ h) Goodwill and intangible assets qualitative assessment, that it is more likely than not that the fair value of the reporting unit is greater than the carrying amount no additional procedures are performed; however, if the Company determines that it is more likely than not that the fair value of the reporting unit is less than the carrying amount the Company will compare the fair value of the reporting unit to its carrying amount. Any excess of the carrying amount 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 considering 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. ​ MSRs associated with loans originated and sold, where servicing is retained, are initially capitalized at fair value and included in intangible assets in the consolidated statements of financial condition. For subsequent measurement purposes, the Company measures servicing assets based on the lower of cost or market using the amortization method. The values of these capitalized servicing rights are amortized as an offset to the loan servicing income earned in relation to the servicing revenue expected to be earned. The carrying values of these rights are reviewed quarterly for impairment based on the fair value of those assets. For purposes of impairment evaluation and measurement, management stratifies MSRs based on the predominant risk characteristics of the underlying loans, including loan type and loan term. If, by individual stratum, the carrying amount of these MSRs exceeds fair value, a valuation allowance is established and the impairment is recognized in mortgage banking income. If the fair value of impaired MSRs subsequently increases, management recognizes the increase in fair value in current period mortgage banking income and, through a reduction in the valuation allowance, adjusts the carrying value of the MSRs to a level not in excess of amortized cost. ​ i) Reserve for Mortgage Loan Repurchase Losses– ​ The Company establishes mortgage repurchase reserves related to various representations and warranties that reflect management’s estimate of losses based on a combination of factors. Such factors incorporate actual and historic loss history, delinquency trends in the portfolio and economic conditions. The Company establishes a reserve at the time loans are sold and updates the reserve estimate quarterly during the estimated loan life. The repurchase reserve is included in other liabilities in the consolidated statements of financial condition. ​ j) Other real estate owned ​ k) Bank-owned life insurance ​ l) Securities purchased under agreements to resell and securities sold under agreements to repurchase ​ m) Stock-based compensation ​ The fair value of stock options is measured using a Black-Scholes model. The fair value of time-based restricted stock awards and performance stock units with performance based vesting criteria is based on the Company’s stock price on the date of grant. The fair value of performance stock units with market-based vesting criteria is measured using a Monte Carlo simulation model. 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. 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. 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 primarily carry a maximum contractual term of ten years. To the extent that any award is forfeited, surrendered, terminated, expires, or lapses without being vested or exercised, the shares of stock subject to such award not delivered are again made available for awards under the Plan. ​ Excess tax benefits and tax deficiencies (including tax benefits of dividends on share-based payment awards) are recognized in the consolidated statements of operations as a component of income tax expense or benefit and are classified as an operating activity within the Company’s consolidated statements of cash flows. 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. 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. ​ n) Income taxes ​ 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. ​ o) Earnings per share ​ p) Interest Rate Swap Derivatives ​ 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. ​ q) Treasury stock 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. ​ r) Acquisition activities ​ 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. ​

Maturities and paydowns of available-for-sale securities during 2021 and 2020 totaled $235.9 million and $271.5 million, respectively. There were no sales of available-for-sale securities during 2021 or 2020. ​ At December 31, 2021 and 2020, the Company’s available-for-sale investment portfolio was primarily comprised of mortgage-backed securities, and all mortgage-backed securities were backed by GSE collateral such as FHLMC and FNMA and the government owned agency GNMA. ​ The tables below summarize the available-for-sale securities with unrealized losses as of the dates shown, along with the length of the impairment period: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2021 ​ ​ Less than 12 months ​ 12 months or more ​ Total ​ Fair Unrealized Fair Unrealized Fair Unrealized ​ ​ value ​ losses ​ value ​ losses ​ value ​ losses Mortgage-backed securities: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Residential mortgage pass-through securities issued or guaranteed by U.S. Government agencies or sponsored enterprises ​ $ 163,579 ​ $ (4,404) ​ $ 22,852 ​ $ (859) ​ $ 186,431 ​ $ (5,263) Other residential MBS issued or guaranteed by U.S. Government agencies or sponsored enterprises ​ ​ 237,759 ​ ​ (5,593) ​ ​ 48,750 ​ ​ (2,452) ​ ​ 286,509 ​ ​ (8,045) Total ​ $ 401,338 ​ $ (9,997) ​ $ 71,602 ​ $ (3,311) ​ $ 472,940 ​ $ (13,308) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2020 ​ ​ Less than 12 months ​ 12 months or more ​ Total ​ Fair Unrealized Fair Unrealized Fair Unrealized ​ ​ value ​ losses ​ value ​ losses ​ value ​ losses Mortgage-backed securities: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Residential mortgage pass-through securities issued or guaranteed by U.S. Government agencies or sponsored enterprises ​ $ 26,878 ​ $ (42) ​ $ 1 ​ $ — ​ $ 26,879 ​ $ (42) Other residential MBS issued or guaranteed by U.S. Government agencies or sponsored enterprises ​ ​ 95,888 ​ ​ (328) ​ ​ 2,138 ​ ​ (16) ​ ​ 98,026 ​ ​ (344) Corporate debt ​ ​ 1,998 ​ ​ (2) ​ ​ — ​ ​ — ​ ​ 1,998 ​ ​ (2) Total ​ $ 124,764 ​ $ (372) ​ $ 2,139 ​ $ (16) ​ $ 126,903 ​ $ (388) ​ Management evaluated all of the available-for-sale securities in an unrealized loss position at December 31, 2021 and December 31, 2020. The portfolio included 49 securities, which were in an unrealized loss position at December 31, 2021, compared to 22 securities at December 31, 2020. The unrealized losses in the Company’s investment portfolio at December 31, 2021 and 2020 were caused by changes in interest rates. The Company has no intention to sell these securities and believes it will not be required to sell the securities before the recovery of their amortized cost. Management believes that default of the available-for-sale securities is highly unlikely. FHLMC, FNMA and GNMA guaranteed mortgage-backed securities have a long history of zero credit losses, an explicit guarantee by the U.S. government (although limited for FNMA and FHLMC securities) and yields that generally trade based on market views of prepayment and liquidity risk rather than credit risk. ​ Certain securities are pledged as collateral for public deposits, securities sold under agreements to repurchase and to secure borrowing capacity at the FRB, if needed. The fair value of available-for-sale investment securities pledged as collateral totaled $363.4 million and $385.8 million at December 31, 2021 and 2020, respectively. The Bank may also pledge available-for-sale investment securities as collateral for FHLB advances. No securities were pledged for this purpose at December 31, 2021 or 2020. ​ Mortgage-backed securities may have actual maturities that differ from contractual maturities depending on the repayment characteristics and experience of the underlying financial instruments. As of December 31, 2021, municipal securities with an amortized cost and fair value of $0.2 million were due between one to five years. Corporate debt securities with an amortized cost of $2.0 million and fair value of $2.1 million were due after five years through ten years. Other securities with an amortized cost and fair value of $0.5 million as of December 31, 2021 have no stated contractual maturity date. ​ As of December 31, 2021 and December 31, 2020, AIR from available-for-sale investment securities totaled $1.0 million and $1.1 million, respectively, and was included within other assets in the statements of financial condition. ​ Held-to-maturity ​ Held-to-maturity investment securities are summarized as follows as of the dates indicated: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2021 ​ ​ ​ Gross Gross ​ ​ ​ ​ Amortized ​ unrealized ​ unrealized ​ ​ ​ ​ ​ cost ​ gains ​ losses ​ Fair value Mortgage-backed securities: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Residential mortgage pass-through securities issued or guaranteed by U.S. Government agencies or sponsored enterprises ​ $ 312,916 ​ $ 2,061 ​ $ (5,363) ​ $ 309,614 Other residential MBS issued or guaranteed by U.S. Government agencies or sponsored enterprises ​ 296,096 ​ 122 ​ (6,572) ​ 289,646 Total investment securities held-to-maturity ​ $ 609,012 ​ $ 2,183 ​ $ (11,935) ​ $ 599,260 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2020 ​ ​ ​ Gross Gross ​ ​ ​ ​ Amortized ​ unrealized ​ unrealized ​ ​ ​ ​ ​ cost ​ gains ​ losses ​ Fair value Mortgage-backed securities: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Residential mortgage pass-through securities issued or guaranteed by U.S. Government agencies or sponsored enterprises ​ $ 306,187 ​ $ 4,940 ​ $ (197) ​ $ 310,930 Other residential MBS issued or guaranteed by U.S. Government agencies or sponsored enterprises ​ 70,428 ​ 396 ​ (63) ​ 70,761 Total investment securities held-to-maturity ​ $ 376,615 ​ $ 5,336 ​ $ (260) ​ $ 381,691 ​ During 2021 and 2020, purchases of held-to-maturity securities totaled $397.8 million and $284.2 million, respectively.

Management evaluated held-to-maturity securities noting they are backed by loans guaranteed by either U.S. government agencies or U.S. government sponsored entities, and management believes that default is highly unlikely given this governmental backing and long history without credit losses. Additionally, management notes that yields on which the portfolio generally trades are based upon market views of prepayment and liquidity risk and not credit risk. The Company has no intention to sell any held-to-maturity securities and believes it will not be required to sell any held-to-maturity securities before the recovery of their amortized cost. ​ Certain securities are pledged as collateral for public deposits, securities sold under agreements to repurchase and to secure borrowing capacity at the FRB, if needed. The carrying value of held-to-maturity investment securities pledged as collateral totaled $147.3 million and $140.6 million at December 31, 2021 and December 31, 2020, respectively. The Bank may also pledge held-to-maturity investment securities as collateral for FHLB advances. No held-to-maturity investment securities were pledged for this purpose at December 31, 2021 or 2020. ​ Actual maturities of mortgage-backed securities may differ from scheduled maturities depending on the repayment characteristics and experience of the underlying financial instruments. ​ As of December 31, 2021 and December 31, 2020, AIR from held-to-maturity investment securities totaled $0.9 million and $0.7 million, respectively, and was included within other assets in the statements of financial condition.

There was no interest income recognized from non-accrual loans during the years ended December 31, 2021 and 2020. ​ The Company’s internal risk rating system uses a series of grades, which reflect our assessment of the credit quality of loans based on an analysis of the borrower's financial condition, liquidity and ability to meet contractual debt service requirements and are categorized as “Pass”, “Special mention”, “Substandard” and “Doubtful”. For a description of the general characteristics of the risk grades, refer to note 2 Summary of Significant Accounting Policies. ​ The amortized cost basis for all loans as determined by the Company’s

individually ​ We evaluate loans individually when they no longer share risk characteristics with pooled loans. These loans include loans on non-accrual status, loans in bankruptcy, and TDRs described below. If a specific allowance is warranted based on the borrower’s overall financial condition, the specific allowance is calculated based on discounted expected cash flows using the loan’s initial contractual effective interest rate or the fair value of the collateral less selling costs for collateral-dependent loans. ​ A loan is considered collateral-dependent when the borrower is experiencing financial difficulty and repayment is expected to be provided substantially through the operation or sale of the collateral. Management individually evaluates collateral-dependent loans with an amortized cost basis of $250 thousand or more and includes collateral-dependent loans less than $250 thousand within the general allowance population. The amortized cost basis of collateral-dependent loans over $250 thousand was as follows at December 31, 2021 and 2020: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2021 ​ ​ ​ ​ ​ Total amortized ​ Real property ​ Business assets ​ cost basis Commercial ​ ​ ​ ​ ​ ​ ​ ​ Commercial and industrial $ 3,270 ​ $ 1,261 ​ $ 4,531 Owner-occupied commercial real estate ​ 4,012 ​ ​ 255 ​ ​ 4,267 Total Commercial ​ 7,282 ​ ​ 1,516 ​ ​ 8,798 Residential real estate ​ ​ ​ ​ ​ Senior lien 2,212 ​ — ​ 2,212 Total residential real estate 2,212 ​ — ​ 2,212 Total loans $ 9,494 ​ $ 1,516 ​ $ 11,010 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2020 ​ ​ ​ ​ ​ Total amortized ​ Real property ​ Business assets ​ cost basis Commercial ​ ​ ​ ​ ​ ​ ​ ​ Commercial and industrial $ 7,579 ​ $ 3,005 ​ $ 10,584 Owner-occupied commercial real estate ​ 3,701 ​ ​ 284 ​ ​ 3,985 Food and agribusiness ​ 334 ​ ​ — ​ ​ 334 Total Commercial ​ 11,614 ​ ​ 3,289 ​ ​ 14,903 Commercial real estate non owner-occupied ​ ​ ​ ​ ​ ​ ​ ​ Acquisition/development 1,573 ​ — ​ 1,573 Multifamily 1,523 ​ — ​ 1,523 Total commercial real estate 3,096 ​ — ​ 3,096 Residential real estate ​ ​ ​ ​ ​ Senior lien 2,021 ​ — ​ 2,021 Total residential real estate 2,021 ​ — ​ 2,021 Total loans $ 16,731 ​ $ 3,289 ​ $ 20,020 ​ Loan modifications and troubled debt restructurings ​ The Company’s policy is to review each prospective credit to determine the appropriateness and the adequacy of security or collateral prior to making a loan. In the event of borrower default, the Company seeks recovery in compliance with lending laws, the respective loan agreements, and credit monitoring and remediation procedures that may include restructuring a loan to provide a concession by the Company to the borrower from their original terms due to borrower financial difficulties in order to facilitate repayment. Additionally, if a borrower’s repayment obligation has been discharged by a court, and that debt has not been reaffirmed by the borrower, regardless of past due status, the loan is considered to be a TDR. ​ The CARES Act afforded financial institutions the option to modify loans within certain parameters in response to the COVID-19 pandemic without requiring the modifications to be classified as TDRs under ASC Topic 310 if the borrower has been adversely impacted by COVID-19 and was current on their loan payments. The Company modified 19 loans totaling $9.9 million during the year ended December 31, 2021 and 510 loans totaling $519.0 million during the year ended December 31, 2020, due to the effects of the COVID-19 pandemic, that were not classified as TDRs. Modified loans that remained on a payment deferral plan, paying interest only, at December 31, 2021 totaled $5.3 million, or 0.1% of the total loan population. At December 31, 2021, $206 thousand of loan modifications related to COVID-19 were a subsequent modification and one loan totaling $206 thousand was classified as non-accrual. At December 31, 2020, modified loans that remained on a payment deferral plan totaled $173.6 million, or 4.0% of the total loan portfolio, of which 26.2% were a subsequent modification. ​ During 2021, the Company restructured four loans with an amortized cost basis of $1.1 million to facilitate repayment that are considered TDRs. Loan modifications were a reduction of the principal payment, a reduction in interest rate, or an extension of term.

The Company had no TDRs that were modified within the past 12 months and had defaulted on their restructured terms during the year ended December 31, 2021. During 2020, the Company had three TDRs totaling $3.4 million that had been modified within the prior 12 months and defaulted on their restructured terms. For purposes of this disclosure, the Company considers “default” to mean 90 days or more past due on principal or interest. The allowance for credit losses related to TDRs on non-accrual status is determined by individual evaluation, including collateral adequacy, using the same process as loans on non-accrual status which are not classified as TDRs. ​

Within the segments, the portfolio was further disaggregated into classes of loans with similar attributes and risk characteristics for purposes of developing the underlying data used within the discounted cash flow model including, but not limited to, prepayment and recovery rates as well as loss rates tied to macro-economic conditions within management’s reasonable and supportable forecast. The ACL also includes subjective adjustments based upon qualitative risk factors including asset quality, loss trends, lending management, portfolio growth and loan review/internal audit results. ​ Net charge-offs on loans during the year ended December 31, 2021 were $1.3 million. The Company recorded a provision release of $9.3 million during 2021, which included a provision release of $8.8 million for funded loans and a provision release of $0.5 million for unfunded loan commitments. Provision release was driven by strong asset quality and an improved outlook in the CECL model’s underlying economic forecast. ​ Net charge-offs on loans during the year ended December 31, 2020 were $2.7 million. The Company recorded total provision expense of $17.6 million during 2020, which included a provision expense of $17.5 million for funded loans and a provision expense of $0.1 million for unfunded loan commitments. Provision expense was recorded to provide coverage for the impact of deteriorating economic conditions as a result of COVID-19 and to support non-PPP originated loan growth. ​ The Company has elected to exclude AIR from the allowance for credit losses calculation. As of December 31, 2021 and December 31, 2020, AIR from loans totaled $15.7 million and $16.7 million, respectively.

Regulatory Capital
Regulatory Capital	Note 14 Regulatory Capital ​ As a bank holding company that has elected to be treated as a financial holding company, the Company and NBH Bank is subject to regulatory capital adequacy requirements implemented by the Federal Reserve, including maintaining capital positions at the “well-capitalized” level. The federal banking agencies have risk-based capital adequacy regulations intended to provide a measure of capital adequacy that reflects the degree of risk associated with a banking organization’s operations. Under these regulations, assets are assigned to one of several risk categories, and nominal dollar amounts of assets and credit equivalent amounts of off-balance-sheet items are multiplied by a risk-adjustment percentage for the category. ​ Under the Basel III requirements, at December 31, 2021 and 2020, the Company and the Bank met all capital requirements, including the capital conservation buffer of 2.5%.

Revenue from Contracts with Clients	Note 15 Revenue from Contracts with Clients ​ Revenue is recognized when obligations under the terms of a contract with clients are satisfied. Below is the detail of the Company’s revenue from contracts with clients. ​ Service charges and other fees ​ Service charge fees are primarily comprised of monthly service fees, check orders, and other deposit account related fees. Other fees include revenue from processing ​ Bank card fees ​ Bank card fees are primarily comprised of debit card income, ATM fees, merchant services income, and other fees. Debit card income is primarily comprised of interchange fees earned whenever the Company’s debit cards are processed through card payment networks such as Visa. ATM fees are primarily generated when a Bank cardholder uses a non-Bank ATM or a non-Bank cardholder uses a Bank ATM. Merchant services income mainly represents fees charged to merchants to process their debit card transactions. The Company’s performance obligation for bank card fees are largely satisfied, and related revenue recognized, when the services are rendered or upon completion. Payment is typically received immediately or in the following month. ​ Gain on OREO sales, net ​ Gain on OREO sales, net is recognized when the Company meets its performance obligation to transfer title to the buyer. The gain or loss is measured as the excess of the proceeds received compared to the OREO carrying value. Sales proceeds are received in cash at the time of transfer. ​ The following table presents non-interest income, segregated by revenue streams in-scope and out-of-scope of Topic 606, and non-interest expense in-scope of Topic 606 for the years ended December 31, 2021, 2020 and 2019. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ For the years ended December 31, ​ 2021 2020 2019 Non-interest income ​ ​ ​ ​ ​ ​ ​ ​ ​ In-scope of Topic 606: ​ ​ ​ ​ ​ ​ ​ ​ ​ Service charges and other fees ​ $ 18,066 ​ $ 16,913 ​ $ 19,720 Bank card fees ​ ​ 17,693 ​ ​ 15,446 ​ ​ 14,595 Non-interest income (in-scope of Topic 606) ​ ​ 35,759 ​ ​ 32,359 ​ ​ 34,315 Non-interest income (out-of-scope of Topic 606) ​ ​ 69,975 ​ ​ 107,899 ​ ​ 48,437 Total non-interest income ​ $ 105,734 ​ $ 140,258 ​ $ 82,752 Non-interest expense ​ ​ ​ ​ ​ ​ ​ ​ ​ In-scope of Topic 606: ​ ​ ​ ​ ​ ​ ​ ​ ​ Gain on OREO sales, net ​ $ 475 ​ $ 38 ​ 7,193 Total revenue in-scope of Topic 606 ​ $ 36,234 ​ $ 32,397 ​ $ 41,508 ​ Contract acquisition costs ​ The Company utilizes the practical expedient which allows entities to expense immediately contract acquisition costs when the asset that would have resulted from capitalizing these costs would have been amortized in one year or less.

Stock-based Compensation and Benefits
Stock-based Compensation and Benefits	Note 16 Stock-based Compensation and Benefits ​ The Company provides stock-based compensation in accordance with shareholder-approved plans. In 2014, shareholders approved the 2014 Omnibus Incentive Plan (the "2014 Plan"). The 2014 Plan replaces the NBH Holdings Corp. 2009 Equity Incentive Plan (the "Prior Plan"), pursuant to which the Company granted equity awards prior to the approval of the 2014 Plan. Pursuant to the 2014 Plan, the Compensation Committee of the Board of Directors has the authority to grant, from time to time, awards of stock options, stock appreciation rights, restricted stock, restricted stock units, performance units, other stock-based awards, or any combination thereof to eligible persons. ​ As of December 31, 2021, the aggregate number of Class A common stock available for issuance under the 2014 Plan is 4,048,761 shares. Any shares that are subject to stock options or stock appreciation rights under the 2014 Plan will be counted against the amount available for issuance as one share for every one share granted, and any shares that are subject to awards under the 2014 Plan other than stock options or stock appreciation rights will be counted against the amount available for issuance as 3.25 shares for every one share granted. The 2014 Plan provides for recycling of shares from both the Prior Plan and the 2014 Plan, the terms of which are further described in the Company's Proxy Statement for its 2014 Annual Meeting of Shareholders. Upon an option exercise, it is the Company’s policy to issue shares from treasury stock. ​ To date, the Company has issued stock options, restricted stock and performance stock units under the plans. The Compensation Committee sets the option exercise price at the time of grant, but in no case is the exercise price less than the fair market value of a share of stock at the date of grant. ​ Stock options ​ The Company issues stock options, which are primarily time-vesting with 1/3 1 ​ Below are the weighted average assumptions used in the Black-Scholes option pricing model to determine fair value of the Company’s stock options granted in 2021, 2020 and 2019: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ 2021 2020 2019 Weighted average fair value $ 9.65 ​ $ 3.37 ​ $ 6.31 Weighted average risk-free interest rate (1) ​ 1.14% ​ ​ 0.44% ​ ​ 2.35% Expected volatility (2) 30.54% ​ ​ 25.08% ​ ​ 20.56% Expected term (years) (3) 6.04 ​ ​ 6.04 ​ ​ 6.05 Dividend yield (4) 2.09% ​ ​ 3.44% ​ ​ 2.00% (1) The risk-free rate for the expected term of the options was based on the U.S. Treasury yield curve at the date of grant and based on the expected term. (2) Expected volatility was calculated using historical volatility of the Company’s stock price for a period commensurate with the expected term of the options. (3) The expected term was estimated to be the average of the contractual vesting term and time to expiration. (4) The dividend yield was calculated in accordance with the Company’s dividend policy at the time of grant. ​ The Company issued stock options in accordance with the 2014 Plan during 2021.

The Company grants performance stock units which represent initial target awards and do not reflect potential increases or decreases resulting from the final performance results, which are to be determined at the end of the three-year performance period (vesting date). The actual number of shares to be awarded at the end of the performance period will range from 0% - 150% of the initial target awards. For awards granted prior to 2020, 60% of the award is based on the Company’s cumulative earnings per share (EPS target) during the performance period, and 40% of the award is based on the Company’s cumulative total shareholder return (TSR target), or TSR, during the performance period. On the vesting date, the Company’s TSR will be compared to the respective TSRs of the companies comprising the KBW Regional Index at the grant date to determine the shares awarded. The fair value of the EPS target portion of the award was determined based on the closing stock price of the Company’s common stock on the grant date. The fair value of the TSR target portion of the award was determined using a Monte Carlo Simulation at the grant date. ​ In establishing the PSU components during 2021 and 2020, the Compensation Committee determined the EPS target portion of the award would not be an effective metric in light of economic uncertainty surrounding COVID-19. Consequently, the Compensation Committee granted an award based upon a relative return on tangible assets (“ROTA”). Annually, the Company’s ROTA is compared to the respective ROTA of companies comprising the KBW Regional Index. At the end of the measurement period, the Company’s ranking will be averaged to determine the shares awarded. The fair value of the relative ROTA award was determined based on the closing stock price of the Company’s common stock on the grant date. ​ The weighted-average grant date fair value per unit for the relative ROTA target portion and the TSR target portion granted during 2021 was $40.16 and $33.11, respectively. The initial weighted-average performance price for the TSR target portion granted during 2021 was $33.04. During 2021 and 2020, the Company awarded an additional 30,024 and 17,852 units due to final performance results related to performance stock units granted in 2018 and 2017, respectively. ​ The following table summarizes restricted stock and performance stock unit activity during 2021 and 2020: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Weighted ​ ​ ​ ​ Weighted ​ ​ Restricted ​ average grant- ​ Performance ​ ​ average grant- ​ ​ stock shares ​ date fair value ​ stock units ​ ​ date fair value Unvested at December 31, 2019 ​ 122,198 ​ $ 34.19 ​ 158,874 ​ $ 31.19 Granted ​ 127,400 ​ ​ 23.94 ​ 68,498 ​ ​ 26.74 Adjustment due to performance ​ — ​ ​ — ​ 17,852 ​ ​ 33.22 Vested ​ (69,444) ​ ​ 32.60 ​ (53,540) ​ ​ 33.22 Forfeited ​ (13,524) ​ ​ 29.25 ​ (6,847) ​ ​ 29.52 Unvested at December 31, 2020 ​ 166,630 ​ $ 27.42 ​ 184,837 ​ $ 29.21 Granted ​ 89,351 ​ ​ 39.99 ​ 52,526 ​ ​ 37.01 Adjustment due to performance ​ — ​ ​ — ​ 30,024 ​ ​ 30.38 Vested ​ (90,645) ​ ​ 29.78 ​ (90,016) ​ ​ 30.38 Forfeited ​ (20,869) ​ ​ 29.54 ​ (16,977) ​ ​ 28.96 Unvested at December 31, 2021 ​ 144,467 ​ $ 33.40 ​ 160,394 ​ $ 31.36 ​ As of December 31, 2021, the total unrecognized compensation cost related to the non-vested restricted stock awards and performance stock units totaled $2.3 million and $2.4 million, respectively, and is expected to be recognized over a weighted average period of approximately 2.0 years and 1.8 years, respectively. Expense related to non-vested restricted stock awards totaled $2.7 million, $2.5 million and $2.2 million during 2021, 2020 and 2019, respectively. Expense related to non-vested performance stock units totaled $2.0 million, $1.8 million and $2.0 million during 2021, 2020 and 2019, respectively. Expense related to non-vested restricted stock awards and units is a component of salaries and benefits in the Company’s consolidated statements of operations. ​ Employee stock purchase plan ​ The 2014 Employee Stock Purchase Plan (“ESPP”) is intended to be a qualified plan within the meaning of Section 423 of the Internal Revenue Code of 1986 and allows eligible employees to purchase shares of common stock through payroll deductions up to a limit of $25,000 per calendar year and 2,000 shares per offering period. The price an employee pays for shares is 90.0% of the fair market value of Company common stock on the last day of the offering period. The offering periods are the six-month periods commencing on March 1 and September 1 of each year and ending on August 31 and February 28 (or February 29 in the case of a leap year) of each year. There are no vesting or other restrictions on the stock purchased by employees under the ESPP. Under the ESPP, the total number of shares of common stock reserved for issuance totaled 400,000 shares, of which 281,896 was available for issuance at December 31, 2021. ​ Under the ESPP, employees purchased 20,980 shares and 23,212 shares during 2021 and 2020, respectively.

The federal NOLs expire in varying amounts through 2034, and the state NOLs expire in varying amounts between 2026 and 2034. While these NOLs are subject to certain restrictions on the amount that can be utilized per year, the Company does not expect any tax attribute carryovers to expire before they are utilized. ​ In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities, if any (including the impact of available carryforward periods), projected future taxable income, and tax-planning strategies in making this assessment. For the years ended December 31, 2021 and 2020, management believes a valuation allowance on the deferred tax asset is not necessary based on the current and future projected earnings of the Company. The Company has no ASC 740-10 unrecognized tax benefits recorded as of December 31, 2021 and 2020 and does not expect the total amount of unrecognized tax benefits to significantly increase within the next 12 months. The Company and its subsidiary bank are subject to income tax by federal, state and local government taxing authorities. The Company is not currently subject to any open income tax examinations; however, the Company’s tax returns for the years ended December 31, 2018 through 2021 remain subject to examination by U.S. federal income tax authorities. The years open to examination by state and local government authorities vary by jurisdiction.

Derivatives	Note 20 Derivatives ​ Risk management objective of using derivatives ​ The Company is exposed to certain risks arising from both its business operations and economic conditions. The Company has established policies stipulating that neither carrying value nor fair value at risk should exceed established guidelines. The Company has designed strategies to confine these risks within the established limits and identify appropriate trade-offs in the financial structure of its balance sheet. These strategies include the use of derivative financial instruments to help achieve the desired balance sheet repricing structure while meeting the desired objectives of its clients. Currently the Company employs certain interest rate swaps that are designated as fair value hedges as well as economic hedges. The Company manages a matched book with respect to its derivative instruments in order to minimize its net risk exposure resulting from such transactions. ​ Fair values of derivative instruments on the balance sheet ​ The table below presents the fair value of the Company’s derivative financial instruments as well as their classification in the consolidated statements of financial condition as of December 31, 2021 and 2020. ​ Information about the valuation methods used to measure fair value is provided in note 22. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Asset derivatives fair value ​ ​ ​ Liability derivatives fair value ​ ​ Balance Sheet ​ December 31, ​ December 31, ​ Balance Sheet ​ December 31, ​ December 31, ​ location 2021 2020 Location 2021 2020 Derivatives designated as hedging instruments: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Interest rate products Other assets ​ $ 477 ​ $ — Other liabilities ​ $ 12,221 ​ $ 38,884 Total derivatives designated as hedging instruments ​ ​ ​ $ 477 ​ $ — ​ ​ ​ $ 12,221 ​ $ 38,884 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Derivatives not designated as hedging instruments: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Interest rate products Other assets ​ $ 8,321 ​ $ 18,149 Other liabilities ​ $ 8,329 ​ $ 18,176 Interest rate lock commitments ​ Other assets ​ ​ 1,792 ​ ​ 7,001 ​ Other liabilities ​ ​ 197 ​ ​ 298 Forward contracts ​ Other assets ​ ​ 91 ​ ​ — ​ Other liabilities ​ ​ 266 ​ ​ 2,622 Total derivatives not designated as hedging instruments ​ ​ ​ $ 10,204 ​ $ 25,150 ​ ​ ​ $ 8,792 ​ $ 21,096 ​ Fair value hedges ​ Interest rate swaps designated as fair value hedges involve the receipt of variable-rate amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without the exchange of the underlying notional amount. As of December 31, 2021, the Company had interest rate swaps with a notional amount of $343.1 million that were designated as fair value hedges. These interest rate swaps were associated with $345.2 million of the Company’s fixed-rate loans included in loans receivable in the statements of financial condition as of December 31, 2021, before a gain of $16.1 million from the fair value hedge adjustment in the carrying amount. ​ As of December 31, 2020, the Company had interest rate swaps with a notional amount of $387.1 million that were designated as fair value hedges. These interest rate swaps were associated with $389.9 million of the Company’s fixed-rate loans as of December 31, 2020, excluding a gain of $40.1 million from the fair value hedge adjustment in the carrying amount. ​ For derivatives designated and that qualify as fair value hedges, the gain or loss on the derivative as well as the offsetting loss or gain on the hedged item attributable to the hedged risk are recognized in earnings. The Company includes the gain or loss on the hedged items in the same line item as the offsetting loss or gain on the related derivatives. ​ Non-designated hedges ​ Derivatives not designated as hedges are not speculative and consist of interest rate swaps with commercial banking clients that facilitate their respective risk management strategies. Interest rate swaps are simultaneously hedged by offsetting interest rate swaps that the Company executes with a third party, such that the Company minimizes its net risk exposure resulting from such transactions. As the interest rate swaps associated with this program do not meet the strict hedge accounting requirements, changes in the fair value of both the client swaps and the offsetting swaps are recognized directly in earnings. As of December 31, 2021, the Company had matched interest rate swap transactions with an aggregate notional amount of $394.4 million related to this program. As of December 31, 2020, the Company had matched interest rate swap transactions with an aggregate notional amount of $456.0 million. ​ As part of its mortgage banking activities, the Company enters into interest rate lock commitments, which are commitments to originate loans where the interest rate on the loan is determined prior to funding and the clients have locked into that interest rate. The Company then locks in the loan and interest rate with an investor and commits to deliver the loan if settlement occurs ("best efforts") or commits to deliver the locked loan in a binding ("mandatory") delivery program with an investor. Fair value changes of certain loans under interest rate lock commitments are hedged with forward sales contracts of MBS. Forward sales contracts of MBS are recorded at fair value with changes in fair value recorded in non-interest income. Interest rate lock commitments and commitments to deliver loans to investors are considered derivatives. The market value of interest rate lock commitments and best efforts contracts are not readily ascertainable with precision because they are not actively traded in stand-alone markets. The Company determines the fair value of interest rate lock commitments and delivery contracts by measuring the fair value of the underlying assets. The fair value of the underlying assets is impacted by current interest rates, remaining origination fees, costs of production to be incurred, and the probability that the interest rate lock commitments will close or will be funded. ​ Certain additional risks arise from these forward delivery contracts in that the counterparties to the contracts may not be able to meet the terms of the contracts. The Company does not expect any counterparty to any MBS contract to fail to meet its obligation. Additional risks inherent in mandatory delivery programs include the risk that, if the Company fails to deliver the loans subject to interest rate risk lock commitments, it will still be obligated to “pair off” MBS to the counterparty. Should this be required, the Company could incur significant costs in acquiring replacement loans and such costs could have an adverse effect in the consolidated financial statements. ​ The fair value of the mortgage banking derivative is recorded as a freestanding asset or liability with the change in value being ​ The Company had interest rate lock commitments with a notional value of $110.0 million and forward contracts with a notional value of $198.3 million at December 31, 2021. At December 31, 2020, the Company had interest rate lock commitments with a notional value of $258.8 million and forward contracts with a notional value of $375.3 million. ​ Effect of derivative instruments on the consolidated statements of operations ​ The tables below present the effect of the Company’s derivative financial instruments on the consolidated statements of operations for 2021 and 2020: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Location of gain (loss) ​ Amount of gain recognized in income on derivatives Derivatives in fair value ​ recognized in income on ​ For the years ended December 31, hedging relationships derivatives 2021 2020 Interest rate products Interest and fees on loans ​ $ 4,568 ​ $ 4,405 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Location of gain (loss) ​ Amount of loss recognized in income on hedged items ​ ​ recognized in income on ​ For the years ended December 31, Hedged items hedged items 2021 2020 Interest rate products Interest and fees on loans ​ $ (3,026) $ (6,376) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Location of gain (loss) ​ Amount of gain (loss) recognized in income on derivatives Derivatives not designated ​ recognized in income on ​ For the years ended December 31, as hedging instruments derivatives 2021 2020 Interest rate products Other non-interest expense $ 23 $ (7) Interest rate lock commitments ​ Mortgage banking income ​ ​ (6,852) ​ ​ 7,218 Forward contracts ​ Mortgage banking income ​ ​ 2,447 ​ ​ (2,339) Total ​ ​ $ (4,382) $ 4,872 ​ Credit-risk-related contingent features ​ The Company has agreements with its derivative counterparties that contain a provision where if the Company defaults on any of its indebtedness for reasons other than an error or omission of an administrative or operational nature, including default where repayment of the indebtedness has not been accelerated by the lender, then the Company could also be declared in default on its derivative obligations. ​ The Company also has agreements with certain of its derivative counterparties that contain a provision where if the Company fails to maintain its status as a well/adequately capitalized institution, then the counterparty has the right to terminate the derivative positions and the Company would be required to settle its obligations under the agreements. ​ As of December 31, 2021, the termination value of derivatives in a net liability position related to these agreements was $20.8 million, which includes accrued interest but excludes any adjustment for nonperformance risk. The Company has minimum collateral posting thresholds with certain of its derivative counterparties and, as of December 31, 2021, the Company had posted $21.6 million in eligible collateral. If the Company had breached any of these provisions at December 31, 2021, it could have been required to settle its obligations under the agreements at the termination value.

Commitments and Contingencies
Commitments and Contingencies	Note 21 Commitments and Contingencies ​ In the normal course of business, the Company enters into various off-balance sheet commitments to help meet the financing needs of clients. These financial instruments include commitments to extend credit, commercial and consumer lines of credit and standby letters of credit. The same credit policies are applied to these commitments as the loans in the consolidated statements of financial condition; however, these commitments involve varying degrees of credit risk in excess of the amount recognized in the consolidated statements of financial condition. The total amounts of unused commitments do not necessarily represent future credit exposure or cash requirements, as commitments often expire without being drawn upon. However, the contractual amount of these commitments, offset by any additional collateral pledged, represents the Company’s potential credit loss exposure. ​ Total unfunded commitments at December 31, 2021 and 2020 were as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2021 December 31, 2020 Commitments to fund loans ​ $ 462,151 ​ $ 311,237 Unfunded commitments under lines of credit ​ 530,397 ​ 537,325 Commercial and standby letters of credit ​ 7,321 ​ 7,320 Total unfunded commitments ​ $ 999,869 ​ $ 855,882 ​ Commitments to fund loans ​ Unfunded commitments under lines of credit ​ Commercial and standby letters of credit various forms of “back-up” commitments to guarantee the performance of a client to a third party. While these arrangements represent a potential cash outlay for the Company, the majority of these letters of credit will expire without being drawn upon. Letters of credit are subject to the same underwriting and credit approval process as traditional loans, and as such, many of them have various forms of collateral securing the commitment, which may include real estate, personal property, receivables or marketable securities. ​ Contingencies ​ Mortgage loans sold to investors may be subject to repurchase or indemnification in the event of specific default by the borrower or subsequent discovery that underwriting standards were not met. The Company established a reserve liability for expected losses related to these representations and warranties based upon management’s evaluation of actual and historic loss history, delinquency trends in the portfolio and economic conditions. Charges against the reserve during the year ended December 31, 2021 and 2020 totaling $0.5 million and $0.5 million, respectively, were primarily driven by early payoffs. The Company recorded a repurchase reserve of $2.1 million and $2.7 million at December 31, 2021 and 2020, respectively, which is included in other liabilities in the consolidated statements of financial condition. ​ The following table summarizes mortgage repurchase reserve activity for the periods presented: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ For the years ended December 31, ​ ​ 2021 ​ 2020 Beginning balance ​ $ 2,741 ​ $ 2,589 Provision (released from) charged to operating expense, net ​ ​ (108) ​ ​ 662 Charge-offs ​ ​ (531) ​ ​ (510) Ending balance ​ $ 2,102 ​ $ 2,741 ​ In the ordinary course of business, the Company and the Bank may be subject to litigation. Based upon the available information and advice from the Company’s legal counsel, management does not believe that any potential, threatened or pending litigation to which it is a party will have a material adverse effect on the Company’s liquidity, financial condition or results of operations.

Fair Value Measurements
Fair Value Measurements	Note 22 Fair Value Measurements ​ The Company uses fair value measurements to record fair value adjustments to certain assets and liabilities and to disclose the fair value of its financial instruments. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. For disclosure purposes, the Company groups its financial and non-financial assets and liabilities into three different levels based on the nature of the instrument and the availability and reliability of the information that is used to determine fair value. The three levels are defined as follows: ​ ● Level 1—Includes assets or liabilities in which the valuation methodologies are based on unadjusted quoted prices in active markets for identical assets or liabilities. ​ ● Level 2—Includes assets or liabilities in which the inputs to the valuation methodologies are based on similar assets or liabilities in inactive markets, quoted prices for identical or similar assets or liabilities in inactive markets, and inputs other than quoted prices that are observable, such as interest rates, yield curves, volatilities, prepayment speeds, and other inputs obtained from observable market input. ​ ● Level 3—Includes assets or liabilities in which the inputs to the valuation methodology are based on at least one significant assumption that is not observable in the marketplace. These valuations may rely on management’s judgment and may include internally-developed model-based valuation techniques. ​ Level 1 inputs are considered to be the most transparent and reliable and level 3 inputs are considered to be the least transparent and reliable. The Company assumes the use of the principal market to conduct a transaction of each particular asset or liability being measured and then considers the assumptions that market participants would use when pricing the asset or liability. Whenever possible, the Company first looks for quoted prices for identical assets or liabilities in active markets (level 1 inputs) to value each asset or liability. However, when inputs from identical assets or liabilities on active markets are not available, the Company utilizes market observable data for similar assets and liabilities. The Company maximizes the use of observable inputs and limits the use of unobservable inputs to occasions when observable inputs are not available. The need to use unobservable inputs generally results from the lack of market liquidity of the actual financial instrument or of the underlying collateral. While third party price indications may be available in those cases, limited trading activity can challenge the observability of those inputs. ​ Changes in the valuation inputs used for measuring the fair value of financial instruments may occur due to changes in current market conditions or other factors. Such changes may necessitate a transfer of the financial instruments to another level in the hierarchy based on the new inputs used. The Company recognizes these transfers at the end of the reporting period that the transfer occurs. During 2021 and 2020, there were no transfers of financial instruments between the hierarchy levels. ​ The following is a description of the valuation methodologies used for assets and liabilities measured at fair value, as well as the general classification of each instrument under the valuation hierarchy: ​ Fair Value of Financial Instruments Measured on a Recurring Basis ​ Investment securities available-for-sale ​ Loans held for sale ​ Interest rate swap derivatives ​ Mortgage banking derivatives on market prices for similar financial instruments), which includes matching specific terms and maturities of the forward commitments against applicable investor pricing. ​ The tables below present the financial instruments measured at fair value on a recurring basis as of December 31, 2021 and 2020, in the consolidated statements of financial condition utilizing the hierarchy structure described above: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2021 ​ ​ Level 1 ​ Level 2 ​ Level 3 ​ Total Assets: ​ ​ ​ ​ Investment securities available-for-sale: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Mortgage-backed securities: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Residential mortgage pass-through securities issued or guaranteed by U.S. Government agencies or sponsored enterprises ​ $ — ​ $ 227,696 ​ $ — ​ $ 227,696 Other residential MBS issued or guaranteed by U.S. Government agencies or sponsored enterprises ​ — ​ 461,334 ​ — ​ 461,334 Municipal securities ​ ​ — ​ ​ 237 ​ ​ — ​ ​ 237 Corporate debt ​ ​ — ​ 2,111 ​ — ​ 2,111 Loans held for sale ​ — ​ 139,142 ​ — ​ 139,142 Interest rate swap derivatives ​ — ​ 8,798 ​ — ​ 8,798 Mortgage banking derivatives ​ ​ — ​ ​ — ​ ​ 1,883 ​ ​ 1,883 Total assets at fair value ​ $ — ​ $ 839,318 ​ $ 1,883 ​ $ 841,201 Liabilities: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Interest rate swap derivatives ​ $ — ​ $ 20,550 ​ $ — ​ $ 20,550 Mortgage banking derivatives ​ ​ — ​ ​ — ​ ​ 463 ​ ​ 463 Total liabilities at fair value ​ $ — ​ $ 20,550 ​ $ 463 ​ $ 21,013 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2020 ​ Level 1 Level 2 Level 3 Total Assets: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Investment securities available-for-sale: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Mortgage-backed securities: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Residential mortgage pass-through securities issued or guaranteed by U.S. Government agencies or sponsored enterprises ​ $ — ​ $ 196,334 ​ $ — ​ $ 196,334 Other residential MBS issued or guaranteed by U.S. Government agencies or sponsored enterprises ​ — ​ 462,779 ​ — ​ 462,779 Municipal securities ​ ​ — ​ ​ 318 ​ ​ — ​ ​ 318 Corporate debt ​ ​ — ​ ​ 1,998 ​ ​ — ​ ​ 1,998 Loans held for sale ​ — ​ 247,813 ​ — ​ 247,813 Interest rate swap derivatives ​ — ​ 18,149 ​ — ​ 18,149 Mortgage banking derivatives ​ ​ — ​ ​ — ​ ​ 7,001 ​ ​ 7,001 Total assets at fair value ​ $ — ​ $ 927,391 ​ $ 7,001 ​ $ 934,392 Liabilities: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Interest rate swap derivatives ​ $ — ​ $ 57,060 ​ $ — ​ $ 57,060 Mortgage banking derivatives ​ ​ — ​ ​ — ​ ​ 2,920 ​ ​ 2,920 Total liabilities at fair value ​ $ — ​ $ 57,060 ​ $ 2,920 ​ $ 59,980 ​ The table below details the changes in level 3 financial instruments during 2021: ​ ​ ​ ​ ​ ​ Mortgage banking ​ ​ ​ derivatives, net Balance at December 31, 2020 ​ $ 4,081 Loss included in earnings, net ​ ​ (4,405) Fees and costs included in earnings, net ​ 1,744 Balance at December 31, 2021 ​ $ 1,420 ​ Fair Value of Financial Instruments Measured on a Non-recurring Basis ​ Certain assets may be recorded at fair value on a non-recurring basis as conditions warrant.

Fair Value Measurements
Fair Value of Financial Instruments	Note 23 Fair Value of Financial Instruments ​ The fair value of a financial instrument is the amount that would be exchanged between willing parties, other than in a forced liquidation. Fair value is determined based upon quoted market prices to the extent possible; however, in many instances, there are no quoted market prices for the Company’s various financial instruments. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques that may be significantly impacted by the assumptions used, including the discount rate and estimates of future cash flows. Changes in any of these assumptions could significantly affect the fair value estimates. The fair value of the financial instruments listed below does not reflect a premium or discount that could result from offering all of the Company’s holdings of financial instruments at one time, nor does it reflect the underlying value of the Company, as ASC Topic 825 excludes certain financial instruments and all non-financial instruments from its disclosure requirements.

Summary of Significant Accounting Policies
Cash and cash equivalents	a) Cash and cash equivalents ​
Investment securities	b) Investment securities ​ Management evaluates all investments in an unrealized loss position on a quarterly basis, and more frequently when economic or market conditions warrant such evaluation. 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 security is written down to fair value and the entire loss is recorded in earnings. If either of the above criteria is not met, we evaluate whether the decline in fair value is the result of credit losses or other factors. In making the assessment, we may consider various factors including the extent to which fair value is less than amortized cost, performance on any underlying collateral, downgrades in the ratings of the security by a rating agency, the failure of the issuer to make scheduled interest or principal payments and adverse conditions specifically related to the security. If the assessment indicates that a credit loss exists, the present value of cash flows expected to be collected are compared to the amortized cost basis of the security and any excess is recorded as an allowance for credit loss. When the loss is not considered a result of credit loss, the cost basis of the security is written down to fair value, with the loss charge recognized in AOCI. The Company does not measure expected credit losses for U.S. agency-backed held-to-maturity securities, since the risk of nonpayment of the amortized cost basis is zero. Credit losses are not estimated for AIR from investment securities as interest deemed uncollectible is written off through interest income. ​ Prior to the adoption of ASU 2016-13, declines in the fair value of held-to-maturity and available-for-sale securities below their cost that were deemed to be other-than-temporarily impaired were reflected in earnings as realized losses. In estimating other-than-temporary-impairment prior to January 1, 2020, the Company considered, 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 had the intent to sell the security; and whether it was more likely than not that the Company would be required to sell the security. ​
Non-marketable securities	c) Non-marketable securities
Loans receivable	d) Loans receivable — ​ 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. 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 is discontinued when the collection of principal or interest, in whole or in part, is doubtful. ​ Interest income on acquired loans 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. ​ The CARES Act afforded financial institutions the option to modify loans within certain parameters in response to the COVID-19 pandemic without requiring the modifications to be classified as TDRs if the borrower has been adversely impacted by COVID-19 and was current on their loan payments. The Company has modified loans due to the effects of the COVID-19 pandemic that were not classified as TDRs. Modifications include deferral of principal as well as full-payment deferral for a period ranging from three months to one year. ​
Loans held for sale	e) Loans held for sale — ​ 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 in the consolidated statements of financial condition within other assets or other liabilities, and changes in fair value are recorded net as a component of mortgage banking income 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.
Allowance for credit losses	f) Allowance for credit losses Measurement of Credit Losses on Financial Instruments ​ The ACL represents management’s estimate of lifetime credit losses inherent in loans as of the balance sheet date. The Company measures expected credit losses for loans on a pooled basis when similar risk characteristics exist. The Company has identified four primary loan segments that are further stratified into 11 loan classes to provide more granularity in analyzing loss history based upon specific loss drivers and risk factors affecting each loan class. Generally, the underlying risk of loss for each of these loan classes will follow certain norms/trends in various economic environments. Loans that do not share risk characteristics are evaluated on an individual basis and are not included in the collective evaluation. Those loans include loans on non-accrual status, loans in bankruptcy, and TDRs described below. If a specific allowance is warranted based on the borrower’s overall financial condition, the specific allowance is calculated based on discounted expected cash flows using the loan’s initial contractual effective interest rate or the fair value of the collateral less selling costs for collateral-dependent loans. ​ The Company utilizes a DCF model developed within a third-party software tool to establish expected lifetime credit losses for the loan portfolio. The ACL is calculated as the difference between the amortized cost basis and the projections from the DCF analysis. The DCF model allows for individual life of loan cash flow modeling, excluding extensions and renewals, using loan-specific interest rates and repayment schedules adjusted for estimated prepayment rates and loss recovery timing delays. The model incorporates forecasts of certain national macroeconomic factors, including unemployment rates, HPI, retail sales and GDP, which drive correlated probability of default (“PD”) and loss given default (“LGD”) rates. PD and LGD, in turn, drive the losses predicted in establishing our ACL. PD and LGD rates along with prepayment rates and loss recovery time delays are determined at a loan class level making use of both internal and peer historical loss rate data. The determination and application of the ACL accounting policy involves judgments, estimates, and uncertainties that are subject to change. For periods beyond the reasonable and supportable forecast period, we revert to historical long-term average loss rates on a straight-line basis. The length of the forecast period spans four quarters. The length of the reversion period is based on management’s assessment of the length and pattern of the current economic cycle and typically ranges from four to eight quarters. ​ Management accounts for the inherent uncertainty of the underlying economic forecast by reviewing and weighting alternate forecast scenarios. Additionally, the ACL calculation includes subjective adjustments for qualitative risk factors that are likely to cause estimated credit losses to differ from historical experience. These qualitative adjustments may increase or reduce reserve levels and include adjustments for lending management experience and risk tolerance, loan review and audit results, asset quality and portfolio trends, loan portfolio growth and industry concentrations. The Company has elected to exclude AIR from the allowance for credit losses calculation. When a loan is placed on non-accrual, any recorded AIR is reversed against interest income. ​ The determination and application of the ACL accounting policy involves judgments, estimates, and uncertainties that are subject to change. Changes in these assumptions, estimates or the conditions surrounding them may have a material impact on our financial condition, liquidity or results of operations. Various regulatory agencies, as an integral part of the examination process, periodically review the ACL. Such agencies may require the Company to recognize additions to the ACL or reserve increases to adversely graded classified loans based on their judgments about information available to them at the time of their examinations. ​ The ACL is decreased by net charge-offs and is increased by provisions for loan losses that are charged to the statements of operations. Charge-offs, if any, are typically measured for each loan based on a thorough analysis of the most probable source of repayment, such as 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. When it is determined that specific loans, or portions thereof, are uncollectible, these amounts are charged off against the ACL. ​ 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. Credit quality indicators are reviewed and updated in accordance with internal policy based on loan balance and risk rating. Interest accrual is discontinued on doubtful loans and certain substandard loans. ​ Unfunded loan commitments ​ In addition to the ACL for funded loans, the Company maintains reserves to cover the risk of loss associated with off-balance sheet unfunded loan commitments. The allowance for off-balance sheet credit losses is maintained within the other liabilities in the statements of financial condition. Under the CECL framework, adjustments to this liability are recorded as provision for credit losses in the statements of operations. Unfunded loan commitment balances are evaluated by loan class and further segregated by revolving and non-revolving commitments. In order to establish the required level of reserve, the Company applies average historical utilization rates and ACL loan model loss rates for each loan class to the outstanding unfunded commitment balances. ​ Prior to the adoption of ASU 2016-13, the Company’s determination of the allowance took 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 acquisitions, loan structures, growth factors and other elements that warrant recognition. ​ Under the prior incurred loss methodology, the Company routinely evaluated adversely risk-rated credits for impairment. Impairment, if any, was 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 were established for loans with similar characteristics. In this process, general allowance factors were 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 were likely to cause estimated credit losses to differ from historical experience. To the extent that the data supporting such factors had limitations, management’s judgment and experience played a key role in determining the allowance estimates.

Goodwill and intangible assets	h) Goodwill and intangible assets qualitative assessment, that it is more likely than not that the fair value of the reporting unit is greater than the carrying amount no additional procedures are performed; however, if the Company determines that it is more likely than not that the fair value of the reporting unit is less than the carrying amount the Company will compare the fair value of the reporting unit to its carrying amount. Any excess of the carrying amount 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 considering 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. ​ MSRs associated with loans originated and sold, where servicing is retained, are initially capitalized at fair value and included in intangible assets in the consolidated statements of financial condition. For subsequent measurement purposes, the Company measures servicing assets based on the lower of cost or market using the amortization method. The values of these capitalized servicing rights are amortized as an offset to the loan servicing income earned in relation to the servicing revenue expected to be earned. The carrying values of these rights are reviewed quarterly for impairment based on the fair value of those assets. For purposes of impairment evaluation and measurement, management stratifies MSRs based on the predominant risk characteristics of the underlying loans, including loan type and loan term. If, by individual stratum, the carrying amount of these MSRs exceeds fair value, a valuation allowance is established and the impairment is recognized in mortgage banking income. If the fair value of impaired MSRs subsequently increases, management recognizes the increase in fair value in current period mortgage banking income and, through a reduction in the valuation allowance, adjusts the carrying value of the MSRs to a level not in excess of amortized cost.
Reserve for Mortgage Loan Repurchase Losses	i) Reserve for Mortgage Loan Repurchase Losses– ​ The Company establishes mortgage repurchase reserves related to various representations and warranties that reflect management’s estimate of losses based on a combination of factors. Such factors incorporate actual and historic loss history, delinquency trends in the portfolio and economic conditions. The Company establishes a reserve at the time loans are sold and updates the reserve estimate quarterly during the estimated loan life. The repurchase reserve is included in other liabilities in the consolidated statements of financial condition.

Securities purchased under agreements to resell and securities sold under agreements to repurchase	l) Securities purchased under agreements to resell and securities sold under agreements to repurchase ​
Stock-based compensation	m) Stock-based compensation ​ The fair value of stock options is measured using a Black-Scholes model. The fair value of time-based restricted stock awards and performance stock units with performance based vesting criteria is based on the Company’s stock price on the date of grant. The fair value of performance stock units with market-based vesting criteria is measured using a Monte Carlo simulation model. 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. 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. 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 primarily carry a maximum contractual term of ten years. To the extent that any award is forfeited, surrendered, terminated, expires, or lapses without being vested or exercised, the shares of stock subject to such award not delivered are again made available for awards under the Plan. ​ Excess tax benefits and tax deficiencies (including tax benefits of dividends on share-based payment awards) are recognized in the consolidated statements of operations as a component of income tax expense or benefit and are classified as an operating activity within the Company’s consolidated statements of cash flows. 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. 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.
Income taxes	n) Income taxes ​ 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.
Earnings per share	o) Earnings per share ​
Interest Rate Swap Derivatives	p) Interest Rate Swap Derivatives ​ 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. ​
Treasury stock	q) Treasury stock 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.
Acquisition activities	r) Acquisition activities ​ 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.
