Basis of Presentation	Note 1 Basis of Presentation National Bank Holdings Corporation ("NBHC" or the "Company") is a bank holding company that was incorporated in the State of Delaware in 2009. The Company is headquartered in Denver, Colorado, and its primary operations are conducted through its wholly owned subsidiary, NBH Bank (the "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 September 30, 2021, located primarily in Colorado and the greater Kansas City region, and through online and mobile banking products and services. The accompanying interim unaudited consolidated financial statements serve to update the National Bank Holdings Corporation Annual Report on Form 10-K Form 10-K 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. 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 whether new outbreaks of COVID-19 cases will have further 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. The Company's significant accounting policies followed in the preparation of the unaudited consolidated financial statements are disclosed in note 2 of the audited financial statements and notes for the year ended December 31, 2020 and are contained in the Company's Annual Report on Form 10-K Non-marketable securities

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: September 30, 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 $ 189,230 $ (4,508) $ — $ — $ 189,230 $ (4,508) Other residential MBS issued or guaranteed by U.S. Government agencies or sponsored enterprises 182,842 (4,627) 1,496 (9) 184,338 (4,636) Total $ 372,072 $ (9,135) $ 1,496 $ (9) $ 373,568 $ (9,144) 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 September 30, 2021 and December 31, 2020. The portfolio included 33 securities, which were in an unrealized loss position at September 30, 2021, compared to 22 securities at December 31, 2020. The unrealized losses in the Company's investment portfolio at September 30, 2021 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 $383.6 million and $385.8 million at September 30, 2021 and at December 31, 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 September 30, 2021 or December 31, 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 September 30, 2021, municipal securities with an amortized cost and fair value As of September 30, 2021 and December 31, 2020, accrued interest receivable (“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.

Maturities and paydowns of held-to-maturity securities totaled $109.0 million and $58.1 million during the nine months ended September 30, 2021 and 2020, respectively. The held-to-maturity portfolio included 37 securities which were in an unrealized loss position as of September 30, 2021, compared to nine securities at December 31, 2020.

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 $156.2 million and $140.6 million at September 30, 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 September 30, 2021 or December 31, 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 September 30, 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.

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 September 30, 2021 and December 31, 2020: September 30, 2021 Total amortized Real property Business assets cost basis Commercial Commercial and industrial $ 3,604 $ 1,858 $ 5,462 Owner-occupied commercial real estate 4,493 261 4,754 Total Commercial 8,097 2,119 10,216 Commercial real estate non owner-occupied Acquisition/development 1,297 — 1,297 Total commercial real estate 1,297 — 1,297 Residential real estate Senior lien 2,247 — 2,247 Total residential real estate 2,247 — 2,247 Total loans $ 11,641 $ 2,119 $ 13,760 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 14 loans totaling $4.8 million during the nine months ended September 30, 2021 and 483 loans totaling $499.5 million during the nine months ended September 30, 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 at September 30, 2021 totaled $0.9 million. Of those loans, principal payment deferrals totaled $0.3 million and full payment deferrals totaled $0.6 million. At September 30, 2021, $45 thousand of loan modifications related to COVID-19 were a subsequent modification. All COVID-19 modified loans were classified as performing as of September 30, 2021. 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 the three months ended September 30, 2021, the Company added no new TDRs. During the nine months ended September 30, 2021, the Company restructured three loans with an amortized cost basis of $1.4 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 one TDR totaling $36 thousand that was modified within the past 12 months and had defaulted on its restructured terms during the nine months ended September 30, 2021. During the nine months ended September 30, 2020, the Company had no TDRs that were modified within the past 12 months and had 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.

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 three and nine months ended September 30, 2021 and 2020: For the three months ended September 30, For the nine months ended September 30, 2021 2020 2021 2020 Non-interest income In-scope of Topic 606: Service charges and other fees $ 5,286 $ 4,246 $ 13,653 $ 12,453 Bank card fees 4,530 4,039 13,217 11,206 Non-interest income (in-scope of Topic 606) 9,816 8,285 26,870 23,659 Non-interest income (out-of-scope of Topic 606) 18,706 36,247 60,279 83,242 Total non-interest income $ 28,522 $ 44,532 $ 87,149 $ 106,901 Non-interest expense In-scope of Topic 606: Gain (loss) on OREO sales, net $ — $ 119 $ (192) $ 25 Total revenue in-scope of Topic 606 $ 9,816 $ 8,404 $ 26,678 $ 23,684 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. The Company has not capitalized any contract acquisition costs.

Stock-based Compensation and Benefits	Note 12 Stock-based Compensation and Benefits The Company provides stock-based compensation in accordance with shareholder-approved plans and is authorized to issue 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. Stock options The Company issues stock options, which are primarily time-vesting with 1/3 The expense associated with the awarded stock options was measured at fair value using a Black-Scholes option-pricing model. The outstanding option awards vest or have vested on a graded basis over 1-4 years of continuous service and have 10-year contractual terms. The following table summarizes stock option activity for the nine months ended September 30, 2021: Weighted average Weighted remaining average contractual Aggregate exercise term in intrinsic Options price years value Outstanding at December 31, 2020 768,129 $ 26.35 6.91 $ 5,224 Granted 81,438 40.10 Exercised (75,986) 27.51 Forfeited (25,915) 27.73 Outstanding at September 30, 2021 747,666 $ 27.68 6.62 $ 9,566 Options exercisable at September 30, 2021 490,448 26.32 5.60 6,980 Options vested and expected to vest 724,844 27.55 6.55 9,373 Stock option expense is a component of salaries and benefits in the consolidated statements of operations and totaled $0.1 million and $0.7 million for the three and nine months ended September 30, 2021, respectively, and $0.1 million and $0.8 million for the three and nine months ended September 30, 2020, respectively. At September 30, 2021, there was $0.5 million of total unrecognized compensation cost related to non-vested stock options granted under the plans. The cost is expected to be recognized over a weighted average period of 2.2 years. Restricted stock awards The Company issues primarily time-based restricted stock awards that vest over a range of a 1 - 3 year period. Restricted stock with time-based vesting was valued at the fair value of the shares on the date of grant as they are assumed to be held beyond the vesting period. Performance stock units 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 will be 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 the nine months ended September 30, 2021, the Company awarded an additional 30,024 units due to final performance results related to performance stock units granted in 2018. The following table summarizes restricted stock and performance stock unit activity during the nine months ended September 30, 2021: Weighted Weighted Restricted average grant- Performance average grant- stock shares date fair value stock units date fair value Unvested at December 31, 2020 166,630 $ 27.42 184,837 $ 29.21 Granted 86,084 39.80 52,526 37.01 Adjustment due to performance — — 30,024 30.38 Vested (77,679) 28.56 (90,016) 30.38 Forfeited (19,568) 29.32 (16,977) 28.96 Unvested at September 30, 2021 155,467 $ 33.47 160,394 $ 31.36 As of September 30, 2021, the total unrecognized compensation cost related to the non-vested restricted stock awards and performance stock units totaled $3.0 million and $2.9 million, respectively, and is expected to be recognized over a weighted average period of approximately 2.1 years and 1.9 years, respectively. Expense related to non-vested restricted stock awards totaled $0.8 million and $2.0 million during the three and nine months ended September 30, 2021, respectively, and $0.7 million and $1.9 million during the three and nine months ended September 30, 2020, respectively. Expense related to non-vested performance stock units totaled $0.8 million and $1.5 million during the three and nine months ended September 30, 2021, respectively, and $0.4 million and $1.3 million during the three and nine months ended September 30, 2020, 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 September 30, 2021. Under the ESPP, employees purchased 20,980 shares and 23,212 shares during the nine months ended September 30, 2021 and 2020, respectively.

Additionally, the Company had 155,467 and 166,630 shares outstanding at September 30, 2021 and December 31, 2020, respectively, of restricted Class A common stock issued but not yet vested under the 2014 Omnibus Incentive Plan that are not included in shares outstanding until such time that they are vested; however, these shares do have voting and certain dividend rights during the vesting period. On February 24, 2021, the Company’s Board of Directors authorized a new program to repurchase up to $75.0 million of the Company’s stock from time to time in either the open market or through privately negotiated transactions. The new program of $75.0 million replaced the previously authorized $50.0 million stock repurchase program announced in February 2020 in its entirety. During the third quarter of 2021, the Company repurchased 527,214 shares for $19.4 million at a weighted average price per share of $36.72. The remaining authorization under the current program as of September 30, 2021 was $55.6 million.

Earnings Per Share
Earnings Per Share	Note 14 Earnings Per Share The Company calculates earnings per share under the two-class method, as certain non-vested share awards contain non-forfeitable rights to dividends. As such, these awards are considered securities that participate in the earnings of the Company. Non-vested shares are discussed further in note 12. The Company had 30,288,131 and 30,594,412 shares of Class A common stock outstanding as of September 30, 2021 and 2020, respectively, exclusive of issued non-vested restricted shares. Certain stock options and non-vested restricted shares are potentially dilutive securities, but are not included in the calculation of diluted earnings per share because to do so would have been anti-dilutive for the three and nine months ended September 30, 2021 and 2020. The following table illustrates the computation of basic and diluted earnings per share for the three and nine months ended September 30, 2021 and 2020: For the three months ended For the nine months ended September 30, 2021 September 30, 2020 September 30, 2021 September 30, 2020 Net income $ 19,825 $ 27,893 $ 70,837 $ 61,422 Less: income allocated to participating securities (34) (36) (101) (96) Income allocated to common shareholders $ 19,791 $ 27,857 $ 70,736 $ 61,326 Weighted average shares outstanding for basic earnings per common share 30,800,590 30,756,116 30,858,759 30,881,325 Dilutive effect of equity awards 264,225 168,107 303,373 189,672 Weighted average shares outstanding for diluted earnings per common share 31,064,815 30,924,223 31,162,132 31,070,997 Basic earnings per share $ 0.64 $ 0.91 $ 2.29 $ 1.99 Diluted earnings per share 0.64 0.90 2.27 1.97 The Company had 747,666 and 802,454 outstanding stock options to purchase common stock at weighted average exercise prices of $27.68 and $26.18 per share at September 30, 2021 and 2020, respectively, which have time-vesting criteria, and as such, any dilution is derived only for the time frame in which the vesting criteria had been met and where the inclusion of those stock options is dilutive. The Company had 315,861 and 364,485 unvested restricted shares and performance stock units issued as of September 30, 2021 and 2020, respectively, which have performance, market and/or time-vesting criteria, and as such, any dilution is derived only for the time frame in which the vesting criteria had been met and where the inclusion of those restricted shares and units is dilutive.

Derivatives	Note 15 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 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 September 30, 2021 and December 31, 2020. Information about the valuation methods used to measure fair value is provided in note 17. Asset derivatives fair value Liability derivatives fair value Balance Sheet September 30, December 31, Balance Sheet September 30, December 31, location 2021 2020 Location 2021 2020 Derivatives designated as hedging instruments: Interest rate products Other assets $ 533 $ — Other liabilities $ 18,555 $ 38,884 Total derivatives designated as hedging instruments $ 533 $ — $ 18,555 $ 38,884 Derivatives not designated as hedging instruments: Interest rate products Other assets $ 10,535 $ 18,149 Other liabilities $ 10,548 $ 18,176 Interest rate lock commitments Other assets 2,170 7,001 Other liabilities 448 298 Forward contracts Other assets 1,022 — Other liabilities 31 2,622 Total derivatives not designated as hedging instruments $ 13,727 $ 25,150 $ 11,027 $ 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 September 30, 2021, the Company had interest rate swaps with a notional amount of $350.3 million, which were designated as fair value hedges of interest rate risk. 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 $350.3 million and $389.9 million of the Company’s fixed-rate loans as of September 30, 2021 and December 31, 2020, respectively, before a gain of $22.9 million and $40.1 million from the fair value hedge adjustment in the carrying amount, included in loans receivable in the statements of financial condition as of September 30, 2021 and December 31, 2020. 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 September 30, 2021, the Company had matched interest rate swap transactions with an aggregate notional amount of $408.9 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 on 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 $171.4 million and forward contracts with a notional value of $267.5 million at September 30, 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 .

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 September 30, 2021, the termination value of derivatives in a net liability position related to these agreements was $30.2 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 September 30, 2021, the Company had posted $32.6 million in eligible collateral. If the Company had breached any of these provisions at September 30, 2021, it could have been required to settle its obligations under the agreements at the termination value.

Commitments and Contingencies
Commitments and Contingencies	Note 16 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 September 30, 2021 and December 31, 2020 were as follows: September 30, 2021 December 31, 2020 Commitments to fund loans $ 476,573 $ 311,237 Unfunded commitments under lines of credit 558,771 537,325 Commercial and standby letters of credit 16,193 7,320 Total unfunded commitments $ 1,051,537 $ 855,882 Commitments to fund loans Unfunded commitments under lines of credit Commercial and standby letters of credit 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 three and nine months ended September 30, 2021 and 2020 were driven by early payoffs and repurchases. The repurchase reserve 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 three months ended September 30, For the nine months ended September 30, 2021 2020 2021 2020 Beginning balance $ 2,398 $ 2,725 $ 2,741 $ 2,589 Provision charged to (released from) operating expense, net 39 285 (62) 604 Charge-offs (150) (214) (392) (397) Ending balance $ 2,287 $ 2,796 $ 2,287 $ 2,796 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 17 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 the nine months ended September 30, 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 appropriately reflect nonperformance risk in the fair value measurements. The credit valuation adjustment is the dollar amount of the fair value adjustment related to credit risk and utilizes a probability weighted calculation to quantify the potential loss over the life of the trade. The credit valuation adjustments are calculated by determining the total expected exposure of the derivatives (which incorporates both the current and potential future exposure) and then applying the respective counterparties’ credit spreads to the exposure offset by marketable collateral posted, if any. Certain derivative transactions are executed with counterparties who are large financial institutions ("dealers"). International Swaps and Derivative Association Master Agreements ("ISDA") and Credit Support Annexes ("CSA") are employed for all contracts with dealers. These contracts contain bilateral collateral arrangements.

These non-recurring fair value measurements typically result from the application of lower of cost or fair value accounting or a write-down occurring during the period. Individually evaluated loans OREO Mortgage servicing rights MSRs assumption ranges of 11.1% to 14.9% with a weighted average rate of 11.2% at September 30, 2021. The weighted average MSRs are subject to impairment testing. The carrying values of these MSRs are reviewed quarterly for impairment based upon the calculation of fair value. For purposes of measuring impairment, the MSRs are stratified into certain risk characteristics including note type and note term. If the valuation model reflects a value less than the carrying value, MSRs are adjusted to fair value through a valuation allowance and the adjustment is included in mortgage banking income in the consolidated statements of operations. There was $0.7 million of recovery on MSRs during the nine months ended September 30, 2021, compared to $0.8 million of impairment during the nine months ended September 30, 2020. The inputs used to determine the fair values of MSRs are considered level 3 inputs in the fair value hierarchy.

Fair Value Measurements
Fair Value of Financial Instruments	Note 18 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. The estimated fair value amounts have been determined by the Company using available market information and appropriate valuation methodologies and are based on the exit price concept within ASC Topic 825 and applied to this disclosure on a prospective basis. Considerable judgment is required to interpret market data in order to develop the estimates of fair value. Accordingly, the estimates presented herein are not necessarily indicative of the amounts the Company could realize in a current market exchange.
