Investment, trust, fiduciary and wealth management services are provided through the Bank’s main operating subsidiaries Amerant Investments and the Cayman Bank. The Company’s main activities are concentrated in its primary markets, with domestic customers located within those markets, and with international customers mainly located in Latin America. The Company does not have any significant concentrations to any one customer. The Company’s Class A common stock, par value $0.10 per common share is listed and trade on the Nasdaq Global Select Market under the symbol “AMTB”. Restructuring Activities The Company continues to work on better aligning its operating structure and resources with its business activities. As part of these efforts, the Company decided to cease the origination of loans in New York and closed its New York City loan production office (the “NY LPO”) in the second quarter of 2021. In addition, the Company decided to outsource the internal audit function during the second quarter of 2021, and eliminated various other support positions throughout 2021. Furthermore, the Company’s Chief Operating Officer (“COO”) stepped down from his position on June 30, 2021. Severance costs resulting from these events were approximately $3.6 million in 2021. Severance costs were recorded as part of “salaries and employees benefits expense” in the Company’s consolidated statement of operations and comprehensive income. Other restructuring expenses in 2021 include: (i) legal and consulting fees of $1.7 million mainly related to the Merger and related transactions, and consulting services; (ii) a $0.8 million right-of-use asset (“ROUA”) impairment associated with the closing of the NY LPO, recorded in “occupancy and equipment expense” in the Company’s consolidated statement of operations and comprehensive income; (iii) branch closure expenses of $0.5 million related to the lease termination of a branch in Fort Lauderdale, Florida, and (iv) digital transformation expenses of $0.4 million. In 2021, the Bank entered into a new multi-year outsourcing agreement with a recognized third party financial technology services provider. Under the terms of this agreement, the third party has assumed full responsibility over a significant number of the Bank’s former support functions and staff, including certain back-office operations. This new relationship entails the transition of our core data processing platform from our current software vendor to the one offered by this third party financial technology service provider. This new agreement is expected to allow the Bank to achieve greater operational efficiencies and deliver advanced solutions and services to our customers. Effective January 1, 2022, there were 80 employees who are no longer working for the Company as a result of this new agreement. Additionally, in connection with the implementation of this agreement in January 2022, the Company recorded approximately $3.9 million in initial estimated contract termination costs. The Company expects to incur additional contract termination costs once existing vendor relationships are terminated in connection with the implementation of this agreement that cannot be reasonably determined at this time. Optimizing Capital Structure Senior Notes. The Company completed in June 2020 a $60.0 million offering of 5.75% senior notes due 2025. See Note 9-Senior Notes, for details. Stock Repurchases . The Company completed in December 2020 a modified Dutch auction tender offer pursuant to which we purchased approximately $54 million of shares of Class B common stock. In March of 2021, the Company’s Board of Directors authorized a stock repurchase program to repurchase up to $40 million of shares of Class B common stock (the “Class B Stock Repurchase Program”). In September 2021, the Company’s Board of Directors authorized a stock repurchase program to repurchase up to $50 million of shares of the Company’s Class A common stock (the “Class A Common Stock Repurchase Program”), and terminated the Class B Common Stock Repurchase Program, previously authorized in March 2021. In 2021 the Company’s Board of Directors authorized the cancellation of all shares of Class A common stock and Class B common stock repurchased in 2021. See Note 17-Stockholders’ Equity for details on all stock repurchase transactions. Clean-Up Merger . In November 2021, the Company’s shareholder’s approved a clean-up merger pursuant to which a newly-created subsidiary of the Company, formed with the only purpose of effecting the clean-up merger, merged with and into the Company (the “Clean-Up Merger”). Under the terms of the Clean-up Merger, among other actions, each outstanding share of Class B common stock was converted to 0.95 of a share of Class A common stock without any action on the part of the holders of Class B common stock. See Note 17-Stockholders’ Equity for details on the Clean-Up Merger. Dividends . In 2021, the Company’s Board of Directors declared a cash dividend of $0.06 per share of the Company’s Class A common stock. Also, on January 19, 2022, the Company’s Board of Directors declared a cash dividend of $0.09 per share of the Company’s Class A common stock. See Note 17-Stockholders’ Equity for details on all dividends declared. Amerant SPV, LLC In May 2021, the Company incorporated a new wholly owned subsidiary, Amerant SPV, LLC, or Amerant SPV. From time to time, the Company may evaluate opportunities to invest and acquire non-controlling interests, through Amerant SPV, in companies it partners with, or may acquire non-controlling interests of fintech and specialty finance companies that the Company believes will be strategic or accretive. In June 2021, the Company made a $2.5 million equity investment in Marstone, Inc (“Marstone”), a digital wealth management fintech it has partnered with to provide digital wealth management and financial planning capabilities to new and existing customers. In connection with this investment, in November 2021, Gerald P. Plush, our Company’s Vice-Chairman, President & CEO, was appointed to Marstone’s Board of Directors. In December 2021, the Company invested an additional $1 million in Marstone. This investment in Marstone is included in the Company’s consolidated balance sheet as other assets. In October 2021, the Company agreed to an equity investment of $2.5 million in Raistone Financial Corp (“Raistone”), a financial technology solutions provider launched in 2017 that offers working capital financing solutions. In December 2021, the Company became a strategic lead investor in the JAM FINTOP Blockchain fund, with (the “Fund”) an initial commitment of approximately $5.4 million that may reach $9.8 million should the fund increase to its maximum target size of $200 million. Initially, the Fund will focus its investments on the blockchain “infrastructure layer” that will help regulated financial institutions compliantly operate blockchain-powered applications in areas such as lending, payments, and exchanges. As a strategic lead investor in the Fund, the Company expects to have access and become an early adopter of this transformational technology. Business Acquisition On May 12, 2021 (the “Acquisition Date”), Amerant Mortgage completed the acquisition of First Mortgage Company (“FMC”). Amerant Mortgage and FMC were ultimately merged, allowing Amerant Mortgage to operate its business nationally with direct access to federal housing agencies. We refer to these transactions as the “FMC Acquisition.” The FMC Acquisition was recorded as a business acquisition using the acquisition method of accounting. The purchase price of approximately $1.0 million was paid in cash and represented the fair value of $0.5 million in mortgage servicing rights (“MSR”) acquired, plus a premium of $0.5 million. No liabilities were assumed in the transaction. The Company allocated the premium paid on the purchase to an indefinite-lived intangible license which was recorded at its fair value of $0.5 million as of the Acquisition Date. The MSRs and premium assigned to an intangible asset were recorded in “Other assets” in the consolidated balance sheets. The transaction resulted in no goodwill. Initial Public Offering and Shares Repurchase On December 21, 2018, the Company completed an initial public offering (the “IPO”). See Note 16 to our consolidated financial statements for more information about the IPO. In December 2018 in connection with the IPO, the Company repurchased approximately 1.4 million shares of Class B common stock from Mercantil Servicios Financieros, C.A. (the “Former Parent”). In March 2019, following the partial exercise of the over-allotment option by the IPO’s underwriters, and completion of certain private placements of shares of the Company’s Class A common stock, the Company repurchased the remaining shares of Class B common stock held by the Former Parent. See Note 16 to our consolidated financial statements for more information about the private placements and the repurchase of Retained Shares previously held by the Former Parent. COVID-19 Pandemic CARES Act. On March 11, 2020, the World Health Organization recognized an outbreak of a novel strain of the coronavirus, COVID-19, as a pandemic. The COVID-19 pandemic adversely affected the economy and resulted in the enactment of the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”). The CARES Act provided emergency economic relief to individuals, small businesses, mid-size companies, large corporations, hospitals and other public health facilities, and state and local governments, and allocated the Small Business Administration, or SBA, $350.0 billion to provide loans of up to $10.0 million per small business as defined in the CARES Act. On April 2, 2020, the Bank began participating in the SBA’s Paycheck Protection Program, or “PPP”, by providing loans to qualifying businesses to cover payroll, rent, mortgage, healthcare, and utilities costs, among other essential expenses. As of December 31, 2021, total PPP loans were $2.7 million, or 0.05% of total loans, compared to $198.5 million, or 3.4% of total loans as of December 31, 2020. In the second quarter of 2021, the Company sold to a third party, in cash, PPP loans with an outstanding balance of approximately $95.1 million, and realized a pretax gain on sale of $3.8 million. The Company retained no loan servicing rights on these PPP loans. In 2020, the Company had salary and compensation benefits totaling $7.8 million, and other operational expenses totaling $0.7 million, directly related to the origination of these PPP loans. In accordance with GAAP, the Company deferred these non-refundable loan origination fees, net of the direct costs of loan originations amortized over the term of the related loans as adjustments to interest income. Main Street Lending. The Company originated loans as part of the Main Street Lending Program in the fourth quarter of 2020. Under this program, which ran through January 8, 2021, the Federal Reserve purchased 95% of each qualifying loan originated by the Company under such program to small and mid-sized businesses. In the fourth quarter of 2020, the Company received fees of approximately $0.5 million from the origination of $56.3 million of loans in this program as of December 31, 2020. Loan Loss Reserve and Modification Program s. On March 26, 2020, the Company began offering loan payment relief options to customers impacted by the COVID-19 pandemic, including interest only and/or forbearance options. These programs continued throughout 2020 and in the six months ended June 30, 2021. In the third quarter of 2021, the Company ceased to offer these loan payment relief options, including interest-only and/or forbearance options. Loans modified under these programs totaled $1.1 billion as of December 31, 2021 and 2020. As of December 31, 2021, $37.1 million, or 0.7% of total loans, were still under the deferral and/or forbearance period ($43.4 million, or 0.7% at December 31, 2020.) In accordance with accounting and regulatory guidance, loans to borrowers benefiting from these measures are not considered troubled debt restructurings, or TDRs. The Company continues to closely monitor the performance of the remaining loans in deferral and/or forbearance periods under the terms of the temporary relief granted. b) Basis of Presentation and Summary of Significant Accounting Policies Emerging Growth Company Section 107 of the JOBS Act provides that, as an “emerging growth company”, or EGC, the Company can take advantage of the extended transition period provided in Section 7(a)(2)(B) of the Securities Act for complying with new or revised accounting standards. Therefore, an EGC can delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. In 2019, the Federal bank regulators recognized or permitted public companies that are EGCs to delay the adoption of accounting pronouncements until those standards would otherwise apply to private companies. The Company intends to take advantage of the benefits of this extended transition period, for as long as it is available and it is consistent with bank regulatory requirements. The following is a description of the significant accounting policies and practices followed by the Company in the preparation of the accompanying consolidated financial statements. These policies conform with generally accepted accounting principles in the United States (GAAP). Segment Reporting The Company is managed using a single segment concept, on a consolidated basis, and management determined that no separate current or historical reportable segment disclosures are required under GAAP. Principles of Consolidation The accompanying consolidated financial statements include the accounts of the Company and its subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation. The Company evaluates whether it has a controlling financial interest in an entity in the form of a variable-interest entity, or a voting interest entity. Non-Controlling Interest Non-controlling interests on the consolidated financial statements include a 49% non-controlling interest of Amerant Mortgage. The Company records net loss attributable to non-controlling interests in its consolidated statement of operations equal to the percentage of the economic or ownership interest retained in the interest of Amerant Mortgage and presents non-controlling interests as a component of stockholders’ equity on the consolidated balance sheets and separately as net loss attributable to non-controlling interests on the consolidated statement of operations and comprehensive income. Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Significant estimates made by management include: i) the determination of the allowance for loan losses; (ii) the fair values of securities and the reporting unit to which goodwill has been assigned during the annual goodwill impairment test; (iii) the cash surrender value of bank owned life insurance; and (iv) the determination of whether the amount of deferred tax assets will more likely than not be realized. Management believes that these estimates are appropriate. Actual results could differ from these estimates. The COVID-19 pandemic has severely restricted the level of economic activity in the U.S. and around the world since March 2020. At the outset of the pandemic, several states and cities across the United States, including the States of Florida, and Texas and cities where we have banking centers, LPOs and where our principal place of business is located, implemented quarantines, restrictions on travel, “shelter at home” orders, and restrictions on types of business that may continue to operate. While most of these measures and restrictions have been lifted, and certain businesses reopened, the Company cannot predict when circumstances may change and whether restrictions that have been lifted will need to be imposed or tightened in the future if viewed as necessary due to public health concerns. Given the uncertainty regarding the spread and severity of the COVID-19 pandemic and its adverse effects on the U.S. and global economies, the impact to the Company’s financial statements cannot be accurately predicted at this time. Income Recognition Interest income is generally recognized on the accrual basis using the interest method. Non-refundable loan origination fees, net of direct costs of originating or acquiring loans, as well as loan purchase premiums and discounts, are deferred and amortized over the term of the related loans as adjustments to interest income using the level yield method. Purchase premiums and discounts on debt securities are amortized as adjustments to interest income over the estimated lives of the securities using the level yield method. Brokerage and advisory activities include brokerage commissions and advisory fees. Brokerage commissions earned are related to the dollar amount of trading volume of customers’ transactions. Commissions and related clearing expenses are recorded on a trade-date basis as securities transactions occur. Advisory fees are derived from investment advisory fees and account administrative services. Investment advisory fees are recorded as earned on a pro rata basis over the term of the contracts, based on a percentage of the average value of assets managed during the period. These fees are assessed and collected at least quarterly. Account administrative fees are charged to customers for the maintenance of their accounts and are earned and collected on a quarterly basis. Fiduciary activities fee income is recognized as earned on a pro rata basis over the term of contracts. Card servicing fees include credit card issuance and credit and debit card interchange fees. Credit card issuance fees are generally recognized over the period in which the cardholders are entitled to use the cards. Interchange fees are recognized when earned. Trade finance servicing fees, which primarily include commissions on letters of credit, are generally recognized over the service period on a straight line basis. Deposits and services fees include service charges on deposit accounts, fees for banking services provided to customers including wire transfers, overdrafts and non-sufficient funds. Revenue from these sources is generally recognized in accordance with published deposit account agreements for customer accounts or when fixed and determinable per contractual agreements. Loan-level derivative income is generated from back-to-back derivative transactions with commercial loan clients and with brokers. The Company earns a fee upon inception of the back-to-back derivative transactions, corresponding to the spread between a wholesale rate and a retail rate. Data processing, rental income and fees for other services to related parties are recognized as the services are provided in accordance with the terms of the service agreements. Earnings per Share Basic earnings per share is computed by dividing net income available to common stockholders by the weighted-average number of common shares outstanding during each period. Unvested shares of restricted stock are excluded from the basic earnings per share computation. Diluted net income per common share reflects the number of additional common stock that would have been outstanding if the dilutive potential common stock had been issued. Dilutive potential common stock consist of unvested shares of restricted stock, restricted stock units and performance share units outstanding during the period. The dilutive effect of potential common stock is calculated by applying the treasury stock method. The latter assumes dilutive potential common stock are issued and outstanding and the proceeds from the exercise, are used to purchase common stock at the average market price during the period. The difference between the numbers of dilutive potential common stock issued and the number of shares purchased is included as incremental shares in the denominator to compute diluted net income per common stock. Dilutive potential common stock are excluded from the diluted earnings per share computation in the period in which the effect is anti-dilutive. Changes in the number of shares outstanding as a result of stock dividends, stock splits, stock exchanges or reverse stock splits are given effect retroactively for all periods presented to reflect those changes in capital structure. Stock-based Compensation The Company may grant share-based compensation and other related awards to its non-employee directors, officers, employees and certain consultants. Compensation cost is measured based on the estimated fair value of the award at the grant date and recognized in earnings as an increase in additional paid in capital on a straight -line basis over the requisite service period or vesting period. The fair value of the unvested shares of restricted stock and restricted stock units is based on the market price of the Company’s Class A common stock at the date of the grant. The fair value of performance share units at the grant date is based on estimated fair values using an option pricing model. Advertising Expenses Advertising expenses are expensed as incurred, except for media production costs which are expensed upon the first airing of the advertisement, and are included in other noninterest expenses. Voluntary and Involuntary Early Retirement Plan Expenses and other Staff Reduction Costs The Company accounts for voluntary and involuntary early retirement plan expenses and other staff reduction costs by establishing a liability for costs associated with the exit or disposal activity, including severance and other related costs, when the liability is incurred, rather than when we commit to an exit plan. In 2021, salaries and employment benefits include $3.6 million of severance expenses, mainly in connection with the departure of our Chief Operating Officer in the second quarter of 2021, and the elimination of various support functions and other actions during the year in connection with the Company’s ongoing transformation and efficiency improvement efforts. On October 9, 2020, the Board of Directors of the Company adopted a voluntary early retirement plan for certain eligible long-term employees ( the “2020 Voluntary Plan”) and an involuntary severance plan for certain other positions (the “2020 Involuntary Plan”) consistent with the Company’s effort to streamline operations and better align its operating structure with its business activities. The employees that elected to participate in the 2020 Voluntary Plan retired on or before December 31, 2020. The 2020 Involuntary Plan impacted employees most of whom no longer worked for the Company and/or its subsidiaries by December 31, 2020. On December 28, 2020, the Company determined the termination costs related to the 2020 Voluntary Plan and the 2020 Involuntary Plan. The Company incurred approximately $3.5 million and $1.8 million in voluntary and involuntary early retirement plan expenses, respectively, reported in salaries and benefits expense in the fourth quarter of 2020 in connection with the 2020 Voluntary Plan and the 2020 Involuntary Plan, respectively, the majority of which will be paid over time in the form of installment payments until December 2021. Offering Expenses Specific, non-reimbursable, incremental costs directly attributable to a proposed or actual securities offerings are deferred and charged against the gross proceeds of the offering. Cash and Cash Equivalents The Company has defined as cash equivalents those highly liquid instruments purchased with an original maturity of three months or less and include cash and cash due from banks, federal funds sold and deposits with banks. The Company must comply with federal regulations requiring the maintenance of minimum reserve balances against its deposits. Effective March 26, 2020, the Board of Governors of the Federal Reserve System reduced reserve requirements ratios to zero percent in response to the COVID-19 pandemic, therefore, there were no reserve requirements at December 31, 2021 and 2020. The Company maintains some of its cash deposited with third-party depository institutions for amounts that, at times, may be in excess of federally-insured limits mandated by the Federal Deposit Insurance Corporation, or FDIC. Securities The Company classifies its investments in securities as debt securities available for sale, debt securities held to maturity and equity securities with readily determinable fair value not held for trading. Securities classified as debt securities available for sale are carried at fair value with unrealized gains and losses included in accumulated other comprehensive income (“AOCI”) or accumulated other comprehensive loss (“AOCL”) in stockholders’ equity on an after-tax basis. Equity securities with readily determinable fair value not held for trading primarily consists of mutual funds carried at fair value with unrealized gains and losses included in earnings. Equity securities were classified as available for sale at December 31, 2018 in accordance with GAAP. Securities classified as debt securities held to maturity are securities the Company has both the ability and intent to hold until maturity and are carried at amortized cost. Investments in stock issued by the Federal Reserve and Federal Home Loan Bank of Atlanta (“FHLB”) are stated at their original cost, which approximates their realizable value. Realized gains and losses from sales of securities are recorded on the trade date and are determined using the specific identification method. Securities purchased or sold are recorded on the consolidated balance sheets as of the trade date. Receivables and payables to and from clearing organizations relating to outstanding transactions are included in other assets or other liabilities. At December 31, 2021 and 2020 securities receivables amounted to $1.5 million and $1.9 million, respectively. At December 31, 2021, securities payable related to pending settlement of purchases amounted to $25.2 million. We had no securities payable at December 31, 2020. The Company considers an investment in debt securities to be impaired when a decline in fair value below the amortized cost basis is other-than-temporary. When an investment in debt securities is considered to be other-than-temporarily impaired, the cost basis of the individual debt security is written down through earnings by an amount that corresponds to the credit component of the other-than-temporary impairment. The amount of the other-than-temporary impairment that corresponds to the noncredit component of the other-than-temporary impairment is recorded in AOCI and is associated with debt securities which the Company does not intend to sell and it is more likely than not that the Company will not be required to sell the debt securities prior to the recovery of its fair value. The Company estimates the credit component of other-than-temporary impairment using a discounted cash flow model. The Company estimates the expected cash flows of the underlying collateral using third party vendor models that incorporate management’s best estimate of current key assumptions, such as default rates, loss severity and prepayment rates (based on historical performance and stress test scenarios). Assumptions used can vary widely from debt security to debt security and are influenced by such factors as current debt service coverage ratio, historical prepayment rates, expected prepayment rates, and loans’ current interest rates. The Company then uses, as it deems appropriate, a third party vendor to determine how the underlying collateral cash flows will be distributed to each debt security. The present value of an impaired debt security results from estimating its future cash flows, discounted at the debt security’s effective interest rate. The Company expects to recover the remaining noncredit related unrealized losses included as a component of AOCI or AOCL. Loans Held for Sale, at Lower of Cost or Fair Value Loans originated for investment are transferred into the held for sale classification at the lower of carrying amount or fair value, when they are specifically identified for sale and a formal plan exists to sell them. Mortgage Loans Held for Sale, at Fair Value Mortgage loans originated for sale are carried at fair value, with changes in fair value recognized in current period earnings presented in other income. The fair value is measured on an individual loan basis using quoted market prices and when not available, comparable market value or discounted cash flow analysis may be utilized. Gains and losses on loan sales are recognized in other noninterest income in the consolidated statements of operations and comprehensive income. Loans Held for Investment Loans represent extensions of credit which the Company has the intent and ability to hold for the foreseeable future or until maturity or payoff. These extensions of credit consist of commercial real estate loans, or CRE loans, (including land acquisition, development and construction loans), owner occupied real estate loans, single-family residential loans, commercial loans, loans to financial institutions and acceptances, and consumer loans. Amounts included in the loan portfolio are stated at the amount of unpaid principal, reduced by unamortized net deferred loan fees and origination costs and an allowance for loan losses. Unamortized deferred loan origination costs , net of deferred fees, and premiums paid on purchased indirect consumer loans, amounted to $16.9 million and $15.5 million at December 31, 2021 and 2020, respectively. A loan is placed in nonaccrual status when management believes that collection in full of the principal amount of the loan or related interest is in doubt. Management considers that collectability is in doubt when any of the following factors are present, among others: (1) there is a reasonable probability of inability to collect principal, interest or both, on a loan for which payments are current or delinquent for less than ninety days; or (2) when a required payment of principal, interest or both, is delinquent for ninety days or longer, unless the loan is considered well secured and in the process of collection in accordance with regulatory guidelines. Once a loan to a single borrower has been placed in nonaccrual status, management reviews all loans to the same borrower to determine their appropriate accrual status. When a loan is placed in nonaccrual status, accrual of interest and amortization of net deferred loan fees or costs are discontinued, and any accrued interest receivable is reversed against inter

As of December 31, 2021, this relationship included two residential loans totaling $1.4 million and one commercial loan of $0.8 million, which were not modified (four residential loans totaling $1.5 million which were not modified at December 31, 2020). During 2020, the company charged off $1.9 million against the ALL associated with this commercial loan relationship. The Company believes the specific reserves associated with these loans, which total $0.8 million and $1.0 million at December 31, 2021 and December 31, 2020, respectively, are adequate to cover probable losses given current facts and circumstances.

Credit Risk Quality The sufficiency of the ALL is reviewed monthly by the Chief Risk Officer and the Chief Financial Officer. The Board of Directors considers the ALL as part of its review of the Company’s consolidated financial statements. As of December 31, 2021 and 2020, the Company believes the ALL to be sufficient to absorb losses in the loans portfolio in accordance with GAAP. Loans may be classified but not considered impaired due to one of the following reasons: (1) the Company has established minimum dollar amount thresholds for loan impairment testing, which results in loans under those thresholds being excluded from impairment testing and therefore not included in impaired loans; and (2) classified loans may be considered nonimpaired because collection of all amounts due is probable. As part of the on-going monitoring of the credit quality of the Company’s loan portfolio, management tracks certain credit quality indicators including trends related primarily to (i) the risk rating of loans, (ii) the loan payment status, (iii) net charge-offs, (iv) nonperforming loans and (v) the general economic conditions in the main geographies where the Company’s borrowers conduct their businesses. The Company considers the views of its regulators as to loan classification and impairment. The Company utilizes a credit risk rating system to identify the risk characteristics of each of its loans, or group of homogeneous loans such as consumer loans. Loans are rated on a quarterly basis (or more frequently when the circumstances require it) on a scale from 1 (worst credit quality) to 10 (best credit quality). Loans are then grouped in five master risk categories for purposes of monitoring rising levels of potential loss risks and to enable the activation of collection or recovery processes as defined in the Company’s Credit Risk Policy. The following is a summary of the master risk categories and their associated loan risk ratings, as well as a description of the general characteristics of the master risk category: Loan Risk Rating Master risk category Nonclassified 4 to 10 Classified 1 to 3 Substandard 3 Doubtful 2 Loss 1 N onclassified This category includes loans considered as Pass (5-10) and Special Mention (4). A loan classified as Pass is considered of sufficient quality to preclude a lower adverse rating. These loans are generally well protected by the current net worth and paying capacity of the borrower or by the value of any collateral received. Special Mention loans are defined as having potential weaknesses that deserve management’s close attention which, if left uncorrected, could potentially result in further credit deterioration. Special Mention loans may include loans originated with certain credit weaknesses or that developed those weaknesses since their origination. Classified This classification indicates the presence of credit weaknesses which could make loan repayment unlikely, such as partial or total late payments and other contractual defaults. Substandard A loan classified substandard is inadequately protected by the sound worth and paying capacity of the borrower or the collateral pledged. They are characterized by the distinct possibility that the Company will sustain some loss if the credit weaknesses are not corrected. Loss potential, while existing in the aggregate amount of substandard loans, does not have to exist in individual assets. Doubtful These loans have all the weaknesses inherent in a loan classified as substandard with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. These are poor quality loans in which neither the collateral, if any, nor the financial condition of the borrower presently ensure collection in full in a reasonable period of time. As a result, the possibility of loss is extremely high. Loss Loans classified as loss are considered uncollectible and of such little value that the continuance as bankable assets is not warranted. This classification does not mean that the assets have absolutely no recovery or salvage value, but not to the point where a write-off should be deferred even though partial recoveries may occur in the future. This classification is based upon current facts, not probabilities. As a result, loans in this category should be promptly charged off in the period in which they are determined to be uncollectible.

Junior Subordinated Debentures Held by Trust Subsidiaries	Junior Subordinated Debentures Held by Trust Subsidiaries At December 31, 2021 and 2020, the Company owns all of the common capital securities issued by 5 statutory trust subsidiaries (“the Trust Subsidiaries”), respectively. These Trust Subsidiaries were first formed by the Company for the purpose of issuing trust preferred securities (“the Trust Preferred Securities”) and investing the proceeds in junior subordinated debentures issued by the Company. The debentures are guaranteed by the Company. The Company records the common capital securities issued by the Trust Subsidiaries in other assets in its consolidated balance sheets using the equity method. The junior subordinated debentures issued to the Trust Subsidiaries, less the common securities of the Trust Subsidiaries, qualify as Tier 1 regulatory capital. The following table provides information on the outstanding Trust Preferred Securities issued by, and the junior subordinated debentures issued to, each of the Trust Subsidiaries as of December 31, 2021 and 2020: December 31, 2021 December 31, 2020 (in thousands) Amount of Principal Amount of Principal Year of Annual Rate of Trust Year of Commercebank Capital Trust VI 9,250 9,537 9,250 9,537 2002 3-M LIBOR + 3.35% 2033 Commercebank Capital Trust VII 8,000 8,248 8,000 8,248 2003 3-M LIBOR + 3.25% 2033 Commercebank Capital Trust VIII 5,000 5,155 5,000 5,155 2004 3-M LIBOR + 2.85% 2034 Commercebank Capital Trust IX 25,000 25,774 25,000 25,774 2006 3-M LIBOR + 1.75% 2038 Commercebank Capital Trust X 15,000 15,464 15,000 15,464 2006 3-M LIBOR + 1.78% 2036 $ 62,250 $ 64,178 $ 62,250 $ 64,178 The Company and the Trust Subsidiaries have the option to defer payment of interest on the obligations for up to 10 semi-annual periods. In 2021 and 2020, no payments of interest have been deferred on these obligations. The Trust Preferred Securities are subject to mandatory redemption, in whole or in part, upon the maturity or early redemption of the debentures. Early redemption premiums may be payable. On January 30, 2020, the Company redeemed all $26.8 million of its outstanding 8.90% trust preferred capital securities issued by Commercebank Capital Trust I (“Capital Trust I”) at a redemption price of 100%. The Company simultaneously redeemed all junior subordinated debentures held by Capital Trust I as part of this redemption transaction.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments	Derivative Instruments From time to time, the Company enters into derivative financial instruments as part of its interest rate management activities and to facilitate customer transactions. Those instruments may or may not be designated and qualify as part of a hedging relationship. The customer derivatives we use for the Company’s account are generally matched against derivatives from third parties, but are not designated as hedging instruments. At December 31, 2021 and 2020 the fair value of the Company’s derivative instruments was as follows: December 31, 2021 December 31, 2020 (in thousands) Other Assets Other Liabilities Other Assets Other Liabilities Interest rate swaps designated as cash flow hedges $ — $ 615 $ — $ 1,658 Interest rate swaps not designated as hedging instruments: Customers 18,858 1,923 39,715 — Third party broker 1,923 18,858 — 39,715 20,781 20,781 39,715 39,715 Interest rate caps not designated as hedging instruments: Customers — 764 — 58 Third party broker 477 — 6 — 477 764 6 58 Mortgage derivatives not designated as hedging instruments: Interest rate lock commitments 581 — — — Forward contracts 31 38 — — 612 38 — — $ 21,870 $ 22,198 $ 39,721 $ 41,431 Derivatives Designated as Hedging Instruments The Company enters into interest rate swap contracts which the Company designates and qualify as cash flow hedges. These interest rate swaps are designed as cash flow hedges to manage the exposure that arises from differences in the amount of the Company’s known or expected cash receipts and the known or expected cash payments on designated debt instruments. These interest rate swap contracts involve the Company’s payment of fixed-rate amounts in exchange for the Company receiving variable-rate payments over the life of the contracts without exchange of the underlying notional amount. At December 31, 2021 and 2020, the Company had five interest rate swap contracts with notional amounts totaling $64.2 million, maturing in the third and fourth quarters of 2022. These contracts were designated as cash flow hedges to manage the exposure of variable rate interest payments on all of the Company’s outstanding variable-rate junior subordinated debentures with principal amounts at December 31, 2021 and 2020 totaling $64.2 million. The Company expects these interest rate swaps to be highly effective in offsetting the effects of changes in interest rates on cash flows associated with the Company’s variable-rate junior subordinated debentures. In 2021 and 2020, the Company recognized unrealized losses of $0.9 million and $0.3 million, respectively, in connection with these interest rate swap contracts, which were included as part of interest expense on junior subordinated debentures in the Company’s consolidated statement of operations and comprehensive income. As of December 31, 2021, the estimated net unrealized losses in accumulated other comprehensive expected to be reclassified into expense in the next twelve months amounted to $0.9 million. In 2019, the Company terminated 16 interest rate swaps that had been designated as cash flow hedges of variable rate interest payments on the outstanding and expected rollover of variable-rate advances from the FHLB. The Company is recognizing the contracts’ cumulative net unrealized gains of $8.9 million in earnings over the remaining original life of the terminated interest rate swaps ranging between one month and seven years. The Company recognized approximately $1.4 million as a reduction of interest expense on FHLB advances in each 2021 and 2020 as a result of this amortization. Derivatives Not Designated as Hedging Instruments Interest Rate Swaps At December 31, 2021 and 2020, the Company had 109 and 76 interest rate swap contracts with customers, respectively, with a total notional amount of $595.4 million and $475.6 million, respectively. These instruments involve the Company’s payment of variable-rate amounts to customers in exchange for the Company receiving fixed-rate payments from customers over the life of the contracts without exchange of the underlying notional amount. In addition, at December 31, 2021 and 2020, the Company had interest rate swap mirror contracts with third party brokers with similar terms. These instruments have maturities ranging from 2 to 13 years in 2021 (3 to 14 years in 2020). In 2019, the Company entered into swap participation agreements with other financial institutions to manage the credit risk exposure on certain interest rate swaps with customers. Under these agreements, the Company, as the beneficiary or guarantor, will receive or make payments from/to the counterparty if the borrower defaults on the related interest rate swap contract. As of December 31, 2021 and 2020, we had two swap participation agreements with an aggregate notional amount of approximately $32.0 million. The notional amount of these agreements is based on the Company’s pro-rata share of the related interest rate swap contracts. As of December 31, 2021 and 2020, the fair value of swap participation agreements was not significant. Interest Rate Caps At December 31, 2021 and 2020, the Company had 19 and 23 interest rate cap contracts with customers with a total notional amount of $432.0 million and $486.5 million, respectively. These instruments involve the Company making payments if an interest rate exceeds the agreed strike price. In addition, at December 31, 2021 and 2020, the Company had 9 and 8 interest rate cap mirror contracts with a third party broker with total notional amounts of $190.7 million and $152.2 million, respectively. These instruments have maturities ranging from less than 1 to 5 years in 2021 (less than 1 to 3 years in 2020). Mortgage Derivatives In 2021, the Company entered into interest rate lock commitments and forward sale contracts to manage the risk exposure in the mortgage banking area. At December 31, 2021, the Company had interest rate lock commitments and forward contracts with notional amounts of $17.9 million and $16.5 million, respectively. Interest rate lock commitments guarantee the funding of residential mortgage loans originated for sale, at specified interest rates and times in the future. Forward sale contracts consist of commitments to deliver mortgage loans, originated and/or purchased, in the secondary market at a future date. In 2021 , the change in the fair value of these instruments was $0.6 million. These amounts were recorded as part of other noninterest income in the consolidated statements of operations and comprehensive income. Credit Risk-Related Contingent Features Some agreements may require the posting of pledged securities when the valuation of the interest rate swap falls below a certain amount. At December 31, 2021 and 2020 the derivative contracts subject to credit-risk related contingent features was as follows: (in thousands) December 31, 2021 December 31, 2020 Fair value of derivative contracts $ 21,396 $ 41,373 Securities Pledged 25,380 52,857 Liquidity exposure $ (3,984) $ (11,484)

This evaluation involves significant judgment by management about assumptions that are subject to change from period to period. Management believes that the weight of all the positive evidence currently available exceeds the negative evidence in support of the realization of the future tax benefits associated with the federal net deferred tax asset. As a result, management has concluded that the federal net deferred tax asset in its entirety will more likely than not be realized. Therefore, a valuation allowance is not considered necessary. If future results differ significantly from the Company’s current projections, a valuation allowance against the net deferred tax asset may be required. At December 31, 2021 and 2020, the Company had accumulated net operating losses (“NOLs”) in the State of Florida of approximately $166.5 million and $163.2 million, respectively. These NOLs are carried forward for a maximum of 20 years based on applicable Florida law. The deferred tax asset related to these NOLs at December 31, 2021 and 2020 is approximately $7.2 million and $7.1 million, respectively. A full valuation allowance has been recorded against the state deferred tax asset related to these NOLs as management believes it is more likely than not that the tax benefit will not be realized.

These loans are generally made to persons who participate or have authority to participate (other than in the capacity of a director) in major policymaking functions of the Company or its affiliates, such as principal owners and management of the Company and their immediate families. Interest income on these loans was approximately $0.2 million and $0.1 million in the years ended December 31, 2021 and 2020, respectively. There were no sales of participations to affiliates in 2021, 2020 and 2019. There were no participations purchased from affiliates in 2021, 2020 and 2019.

These initial services were terminated on June 30, 2019. Under the terms of the agreement, the Company continues to receive custody, safekeeping and information agent services to smaller shareholders. The agreement, which had an initial term of 18 months, was renewed in February 2019 for an additional year, and provides for a monthly fee payable by the Company.

Under the terms of the Clean-up Merger, each outstanding share of Class B common stock was converted to 0.95 of a share of Class A common stock without any action on the part of the holders of Class B common stock; however, any shareholder, together with its affiliates, who owned more than 8.9% of the outstanding shares of Class A common stock a result of the Clean-up Merger, such holder’s shares of Class A common stock or Class B common stock, as the case may have been, was converted into shares of a new class of Non-Voting Class A common stock, solely with respect to holdings that were in excess of the 8.9% limitation. The terms of the Clean-up Merger included the creation of a new class of Non-Voting Class A common stock. Following the Clean-up Merger, no shares of Class B common stock are authorized or outstanding, and November 17, 2021 was the last day they traded on the Nasdaq Global Select Market. In addition, all shareholders who held fractional shares as a result of the Clean-up Merger received a cash payment in lieu of such fractional shares. Following the Clean-up Merger, any holder who beneficially owned fewer than 100 shares of Class A common stock received cash in lieu of Class A common stock. On November, 17, 2021, the Company filed amended and restated articles of incorporation with the Secretary of State of Florida.

There are currently no outstanding shares of preferred stock. Dividends Dividends shall be payable only when, as and if declared by the Board of Directors from lawful available funds, and may be paid in cash, property, or shares of any class or series or other securities or evidences of indebtedness of the Company or any other issuer, as may be determined by resolution or resolutions of the Board of Directors. b) Common Stock Shares of the Company’s Class A common stock issued and outstanding as of December 31, 2021 and 2020 were 35,883,320 and 28,806,344, respectively.

In November 2021, the Company repurchased 281,725 shares of Class A Common Stock that were cashed out in accordance with the terms of the Clean-Up Merger. These shares were repurchased at a price per share of $30.10 and an aggregate purchase price of approximately $8.5 million. In September 2021, the Company’s Board of Directors authorized a stock repurchase program which provides for the potential to repurchase up to $50 million of shares of the Company’s Class A common stock. Under the Class A Common Stock Repurchase Program, repurchases may be made in the open market, by block purchase, in privately negotiated transactions or otherwise in compliance with Rule 10b-18 under the Exchange Act. Repurchases of the Company’s shares of Class A Common Stock (and the timing thereof) will depend upon market conditions, regulatory requirements, other corporate liquidity requirements and priorities and other factors as may be considered in the Company’s sole discretion. Repurchases may also be made pursuant to a trading plan under Rule 10b5-1 under the Exchange Act, which would permit shares to be repurchased when the Company might otherwise be precluded from doing so because of self-imposed trading blackout periods or other regulatory restrictions. The Class A Common Stock Repurchase Program does not obligate the Company to repurchase any particular amount of Class A common stock and may be suspended or discontinued at any time without notice. In 2021, the Company repurchased an aggregate of 893,394 shares of Class A common stock at a weighted average price per share of $31.18, under the Class A Common Stock Repurchase Program.

On March 10, 2021, the Company’s Board of Directors approved a stock repurchase program which provided for the potential repurchase of up to $40 million of shares of the Company’s Class B common stock. Under the Class B Common Stock Repurchase Program, the Company was able to repurchase shares of Class B common stock through open market purchases, by block purchase, in privately-negotiated transactions, or otherwise in compliance with Rule 10b-18 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). The extent to which the Company was able to repurchase its shares of Class B common stock and the timing of such purchases depended upon market conditions, regulatory requirements, other corporate liquidity requirements and priorities and other factors as may have been considered in the Company’s sole discretion. Repurchases may also have been made pursuant to a trading plan under Rule 10b5-1 under the Exchange Act, which would permit shares to be repurchased when the Company might otherwise be precluded from doing so because of self-imposed trading blackout periods or other regulatory restrictions. The Class B Common Stock Repurchase Program did not obligate the Company to repurchase any particular amount of shares of Class B common stock, and may have been suspended or discontinued at any time without notice. In 2021, the Company repurchased an aggregate of 565,232 shares of Class B common stock at a weighted average price per share of $16.92, under the Class B Common Stock Repurchase Program. The aggregate purchase price for these transactions was approximately $9.6 million, including transaction costs. In September 2021, in connection with the Merger, The Company’s Board of Directors terminated the Class B Common Stock Repurchase Program. On December 23, 2020, the Company completed a modified “Dutch auction” tender offer to purchase, for cash, up to $50.0 million of shares of its Class B common stock. The tender offer was oversubscribed and, as result, we accepted to purchase 4,249,785 shares of Class B common stock in the tender offer, which includes an additional 2% of outstanding shares of Class B common stock as permitted under the tender offer rules. The 4,249,785 shares of Class B common stock were purchased at a price of $12.55 per share. The total purchase price for this transaction was $54.1 million, including $0.8 million in related fees and expenses. On February 14 and February 21, 2020, the Company repurchased an aggregate of 932,459 shares of nonvoting Class B common stock in two privately negotiated transactions (collectively, the “2020 Repurchase”) for $16.00 per share of Class B common stock. The aggregate purchase price for these transactions was approximately $15.2 million, including $0.3 million in broker fees and other expenses.The Company funded the 2020 Repurchase with available cash. On March 7, 2019, in connection with the Company’s IPO in 2018, the Company repurchased all of the Former Parent’s 2,112,321 remaining shares of nonvoting Class B common stock at a weighted average price of $13.48 per share with proceeds from the IPO over-allotment exercise and the Private Placements, representing an aggregate purchase price of approximately $28.5 million. The aforementioned 2,112,321 shares of Class B common stock were held in treasury stock under the cost method at December 31, 2019. In 2021 and 2020, the Company’s Board of Directors authorized the cancellation of all shares of Class A common stock and Class B common stock previously held as treasury stock, including all shares repurchased in 2021, 2020, 2019 and 2018. Therefore, The Company had no shares of common stock held in treasury stock at December 31, 2021 and 2020. Subsequent Event. In January 2022, the Company repurchased an aggregate of 652,118 shares of Class A common stock at a weighted average price of $33.96 per share, under the Class A Common Stock Repurchase Program.

On January 31, 2022, the Company announced the completion of the Class A Common Stock repurchase program. Also, on January 31, 2022, the Company announced the launching of a new repurchase program pursuant to which the Company may purchase, from time to time, up to an aggregate amount of $50 million of its shares of Class A common stock (the “New Class A Common Stock Repurchase Program”. Repurchases under the New Class A Common Stock Repurchase Program may be made in the open market, by block purchase, in privately negotiated transactions or otherwise in compliance with Rule 10b-18 under the Exchange Act. The New Class A Common Stock Repurchase Program does not obligate the Company to repurchase any particular amount of Class A common stock and may be suspended or discontinued at any time without notice. The Company has repurchased an aggregate of 709,730 shares of Class A common stock at a weighted average price of $33.52 per share, under the New Class A Common Stock Repurchase Program, through March 3, 2022.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies The Company and its subsidiaries are party to various legal actions arising in the ordinary course of business. In the opinion of management, the outcome of these proceedings will not have a significant effect on the Company’s consolidated financial position or results of operations. The Company is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit, credit card facilities and letters of credit. The Company’s exposure to credit loss in the event of nonperformance by the other party to the financial instrument for loan commitments and letters of credit is represented by the contractual amount of those instruments. The Company uses the same credit policies in making loan commitments and letters of credit as it does for on-balance sheet instruments. The Company controls the credit risk of loan commitments and letters of credit through credit approvals, customer limits, and monitoring procedures. Loan commitments are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Loan commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. The Company evaluates each customer’s credit-worthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the Company upon extension of credit, is based on management’s credit evaluation. Collateral held varies but may include cash, accounts receivable, inventory, property and equipment, real estate in varying stages of development and occupancy, and income-producing commercial properties. Standby letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. Those guarantees are primarily issued to support borrowing arrangements. They generally have one year terms and are renewable annually, if agreed. The credit risk involved in issuing standby letters of credit is generally the same as that involved in extending loan facilities to customers. The Company generally holds deposits, investments and real estate as collateral supporting those commitments. The extent of collateral held for those commitments at December 31, 2021 ranges from unsecured commitments to commitments fully collateralized by cash and securities. Commercial letters of credit are conditional commitments issued by the Company to guarantee payment by a customer to a third party, and are used primarily for importing or exporting goods and are terminated when proper payment is made by the customer. The Company phased out its legacy credit card products to further strengthen its credit quality in 2020. During the first quarter of 2020, the remaining balances related to the credit card product were repaid, therefore, there are no outstanding credit card balances as of December 31, 2021. As a result of these actions, the Company no longer carries off-balance sheet credit risk associated with its former credit card programs. Financial instruments whose contract amount represents off-balance sheet credit risk at December 31, 2021 are generally short-term and are as follows: (in thousands) Approximate Commitments to extend credit $ 899,016 Standby letters of credit 13,897 Commercial letters of credit 18,210 $ 931,123

These Pricing Providers collect, use and incorporate descriptive market data from various sources, quotes and indicators from leading broker dealers to generate independent and objective valuations. The fair value of bank-owned life insurance policies is based on the cash surrender values of the policies as reported by the insurance companies. The valuation techniques and the inputs used in our consolidated financial statements to measure the fair value of our recurring Level 2 financial instruments consider, among other factors, the following: • Similar securities actively traded which are selected from recent market transactions; • Observable market data which includes spreads in relationship to LIBOR, swap curve, and prepayment speed rates, as applicable. • The captured spread and prepayment speed is used to obtain the fair value for each related security. On a quarterly basis, the Company evaluates the reasonableness of the monthly pricing process for the valuation of debt securities available for sale and equity securities not held for trading and derivative instruments. This evaluation includes challenging a random sample of the different types of securities in the investment portfolio as of the end of the quarter selected. This challenge consists of obtaining from the Pricing Providers a document explaining the methodology applied to obtain their fair value assessments for each type of investment included in the sample selection. The Company then analyzes in detail the various inputs used in the fair value calculation, both observable and unobservable (e.g., prepayment speeds, yield curve benchmarks, spreads, delinquency rates). Management considers that the consistent application of this methodology allows the Company to understand and evaluate the categorization of its investment portfolio. The methods described above may produce a fair value calculation that may differ from the net realizable value or may not be reflective of future fair values. Furthermore, while the Company believes its valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of its financial instruments could result in different estimates of fair value at the reporting date. Level 3 Valuation Techniques Mortgage Servicing Rights MSRs are initially and subsequently measured at fair value, with changes in fair value recorded as part of noninterest income. The Company estimates the fair value of MSRs through the use of prevailing market participants assumptions and market participant valuation processes. This valuation is periodically tested and validated against other thrid-party firm valuations. Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis The following tables present the major categories of assets measured at fair value on a non-recurring basis at December 31, 2021 and 2020: December 31, 2021 (in thousands) Carrying Amount Quoted Significant Significant Total Impairments Description Loans held for investment measured for impairments using the fair value of the collateral $ 24,753 $ — $ — $ 24,753 $ 26,334 Other Real Estate Owned 9,720 — — 9,720 80 $ 34,473 $ — $ — $ 34,473 $ 26,414 December 31, 2020 (in thousands) Carrying Amount Quoted Significant Significant Total Impairments Description Loans held for investment measured for impairments using the fair value of the collateral $ 50,199 $ — $ — $ 50,199 $ 19,843 The following table presents the significant unobservable inputs (Level 3) used in the valuation of assets measured at fair value on a nonrecurring basis. Financial Instrument Unobservable Inputs Valuation Methods Discount Range Typical Discount Collateral dependent loans Discount to fair value Appraisal value, as adjusted 0-30% 6-7% Inventory 0-100% 30-50% Accounts receivables 0-100% 20-30% Equipment 0-100% 20-30% Other Real Estate Owned Discount to fair value Appraisal value, as adjusted N/A 6-7% There were no other significant assets or liabilities measured at fair value on a nonrecurring basis at December 31, 2021 and 2020. Collateral Dependent Loans Measured For Impairment The Company measures the impairment of collateral dependent loans based on the fair value of the collateral in accordance with the provisions of ASC-310-35 “Impairment of Loans and Receivables”. The Company primarily uses third party appraisals to assist in measuring impairment on collateral dependent impaired loans. The Company also uses third party appraisal reviewers for loans with an outstanding balance of $1 million and above. These appraisals generally use the market or income approach valuation technique and use market observable data to formulate an opinion of the fair value of the loan’s collateral. However, the appraiser uses professional judgment in determining the fair value of the collateral or properties and may also adjust these values for changes in market conditions subsequent to the appraisal date. When current appraisals are not available for certain loans, the Company uses judgment on market conditions to adjust the most current appraisal. The sales prices may reflect prices of sales contracts not closed and the amount of time required to sell out the real estate project may be derived from current appraisals of similar projects. As a consequence, the fair value of the collateral is considered a Level 3 valuation. Other Real Estate Owned The Company values OREO at the lower of cost or fair value of the property, less cost to sell. The fair value of the property is generally based upon recent appraisal values of the property, less cost to sell. The Company primarily uses third party appraisals to assist in measuring the valuation of OREO. Period revaluations are classified as level 3 as the assumptions used may not be observable. The fair value of a financial instrument represents the price that would be received from its sale in an orderly transaction between market participants at the measurement date. The best indication of the fair value of a financial instrument is determined based upon quoted market prices. However, in many cases, there are no quoted market prices for the Company’s various financial instruments. As a result, the Company derives the fair value of the financial instruments held at the reporting period-end, in part, using present value or other valuation techniques. Those techniques are significantly affected by management’s assumptions, the estimated amount and timing of future cash flows and estimated discount rates included in present value and other techniques. The use of different assumptions could significantly affect the estimated fair values of the Company’s financial instruments. Accordingly, the net realized values could be materially different from the estimates presented below. The following methods and assumptions were used to estimate the fair value of each class of financial instruments for which it is practicable to estimate that value: • Because of their nature and short-term maturities, the carrying values of the following financial instruments were used as a reasonable estimate of their fair value: cash and cash equivalents, interest earning deposits with banks, variable-rate loans with re-pricing terms shorter than twelve months, demand and savings deposits, short-term time deposits and other borrowings. • The fair value of loans held for sale, debt and equity securities, bank owned life insurance and derivative instruments, are based on quoted market prices, when available. If quoted market prices are unavailable, fair value is estimated using the pricing process described in Note 19. • The fair value of commitments and letters of credit is based on the assumption that the Company will be required to perform on all such instruments. The commitment amount approximates estimated fair value. • The fair value of fixed-rate loans, advances from the FHLB, senior notes and junior subordinated debentures are estimated using a present value technique by discounting the future expected contractual cash flows using the current rates at which similar instruments would be issued with comparable credit ratings and terms at the measurement date. • The fair value of long-term time deposits, including certificates of deposit, is determined using a present value technique by discounting the future expected contractual cash flows using current rates at which similar instruments would be issued at the measurement date. The estimated fair value of financial instruments where fair value differs from carrying value are as follows: December 31, 2021 December 31, 2020 (in thousands) Carrying Estimated Carrying Estimated Financial assets Loans $ 2,619,461 $ 2,559,280 $ 2,884,550 $ 2,801,279 Financial liabilities Time deposits 1,048,078 1,057,759 1,547,396 1,569,897 Advances from the FHLB 809,577 819,268 1,050,000 1,078,786 Senior notes 58,894 63,214 58,577 61,528 Junior subordinated debentures 64,178 61,212 64,178 55,912

Regulatory Matters	Regulatory Matters The Company and the Bank are subject to various regulatory requirements administered by federal banking agencies. Amerant Mortgage is an approved Fannie Mae seller and servicer and is subject to certain Lender Adjusted Net Worth requirements. The following is a summary of restrictions related to dividend payments, and capital adequacy as well as Lender Adjusted Net Worth requirement. Dividend Restrictions Dividends payable by the Bank as a national bank subsidiary of the Company, are limited by law and Office of the Comptroller of the Currency (“OCC”) regulations. A dividend may not be paid if the total of all dividends declared by a bank in any calendar year is in excess of the current year’s net income combined with the retained net income of the two preceding years, unless the national bank obtains the approval of the OCC. At December 31, 2021 and 2020, the Bank could have paid dividends of $97.0 million and $17.6 million, respectively, without prior OCC approval. In addition, the Company and the Bank are subject to various general regulatory policies and requirements relating to the payment of dividends, including requirements to maintain capital above regulatory minimums and the maintenance of capital in excess of capital conservation buffers required by the Federal Reserve and OCC capital regulations. Capital Adequacy Under the Basel III capital and prompt corrective action rules, the Company and the Bank must meet specific capital guidelines that involve quantitative measures and qualitative judgments about capital components, risk weightings, and other factors. The Basel III rules became effective for the Company and the Bank on January 1, 2015 with full compliance with all of the requirements being phased in over a multi-year schedule and were fully phased in by January 1, 2019. The Company and the Bank opted to not include the AOCI in computing regulatory capital. As of December 31, 2021, management believes that the Company and the Bank meet all capital adequacy requirements to which they are subject, and are well capitalized. In addition, Basel III rules required the Company and the Bank to hold a minimum capital conservation buffer of 2.50% by 2019. The Company’s capital conservation buffer at year end 2021 and 2020 was 6.6% and 6.0%, respectively, and therefore no regulatory restrictions exist under the applicable capital rules on dividends or discretionary bonuses or other payments. Lender Net Worth Adjusted requirements Amerant Mortgage is currently an approved seller and servicer with Fannie Mae for the purpose of selling Fannie Mae eligible loan production and retaining the MSRs of those same loans. As an approved Fannie Mae seller and servicer, Amerant Mortgage must meet certain net worth covenants outlined in Maintaining Seller/Servicer Eligibility section of the Fannie Mae Selling Guide, the “Selling Guide”. Under the Selling Guide, Amerant Mortgage must meet a minimum net worth requirement of $2.5 million plus 0.25% of the outstanding unpaid principal balance of the portfolio of loans Amerant Mortgage is contractually obligated to service for Fannie Mae (the “Lender Adjusted Net Worth”). As of December 31, 2021, Amerant Mortgage had a Lender Adjusted Net Worth of approximately $4.5 million and was in compliance with requirement. In addition, Amerant Mortgage is subject to net worth decline tolerance requirements that shall not exceed 25% over one quarter or 40% over two consecutive quarters. Amerant Mortgage had a decline in its Lender Adjusted Net Worth of more than 40% over two-consecutive quarterly reporting periods as of December 31, 2021. Amerant Mortgage expects to demonstrate compliance with all financial eligibility requirements by April 30, 2022. Failure to meet the minimum net worth or net worth decline tolerance outlined above, may prompt the suspension of Amerant Mortgage as an approved seller and/or servicer, which would prevent Amerant Mortage from taking down new commitments to deliver loans to Fannie Mae and adding loans to any portfolio that Amerant Mortgage services for Fannie Mae. While Amerant Mortage is not required to operate as an approved Fannie Mae seller and servicer, failure to operate as such may impact Amerant Mortgage’s overall margins, profitability and financial flexibility.

As of December 31, 2020 and 2019, potential dilutive instruments consisted of unvested shares of restricted stock and restricted stock units totaling 248,750 and 530,620, respectively, mainly related to the Company’s IPO in 2018. As of December 31, 2021 and 2019, potential dilutive instruments were included in the diluted earnings per share computation because, when the unamortized deferred compensation cost related to these shares was divided by the average market price per share at those dates, fewer shares would have been purchased than restricted shares assumed issued. Therefore, at those dates, such awards resulted in higher diluted weighted average shares outstanding than basic weighted average shares outstanding, and had a dilutive effect in per share earnings in 2021 and 2019. As of December 31, 2020, potential dilutive instruments were excluded from the diluted earnings per share computation because the Company reported a net loss and their inclusion would have an anti-dilutive effect in per share earnings in 2020. See Note 13 to these audited annual consolidated financial statements for more information on restricted stock, restricted stock units and performance share units transactions in 2021, 2020 and 2019.

Condensed Unconsolidated Holding Companies’ Financial Statements	Condensed Unconsolidated Holding Companies’ Financial Statements The separate condensed unconsolidated financial statements of each of the Company and its wholly-owned subsidiary Amerant Florida have been prepared using the same basis of accounting that the Company used to prepare its consolidated financial statements described in Note 1, except for its investment in subsidiaries which is accounted for using the equity method. Under the equity method, investments in subsidiaries are initially recorded at cost, and they are periodically adjusted due to changes in the interest of the parent company over the net assets of the subsidiaries. The Company records in the results for the period, its participation in the profit or loss of the subsidiaries, and in AOCI its participation in the “Other comprehensive income account” of the subsidiary. In applying the equity method the Company uses the subsidiaries consolidated financial statements at the end of the period prepared under GAAP.

Business, Basis of Presentati_2

Business, Basis of Presentation and Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2021
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Restructuring Activities	Restructuring ActivitiesThe Company continues to work on better aligning its operating structure and resources with its business activities. As part of these efforts, the Company decided to cease the origination of loans in New York and closed its New York City loan production office (the “NY LPO”) in the second quarter of 2021. In addition, the Company decided to outsource the internal audit function during the second quarter of 2021, and eliminated various other support positions throughout 2021. Furthermore, the Company’s Chief Operating Officer (“COO”) stepped down from his position on June 30, 2021.
Segment Reporting	Segment Reporting The Company is managed using a single segment concept, on a consolidated basis, and management determined that no separate current or historical reportable segment disclosures are required under GAAP.
Principles of Consolidation	Principles of Consolidation The accompanying consolidated financial statements include the accounts of the Company and its subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation. The Company evaluates whether it has a controlling financial interest in an entity in the form of a variable-interest entity, or a voting interest entity. Non-Controlling Interest Non-controlling interests on the consolidated financial statements include a 49% non-controlling interest of Amerant Mortgage. The Company records net loss attributable to non-controlling interests in its consolidated statement of operations equal to the percentage of the economic or ownership interest retained in the interest of Amerant Mortgage and presents non-controlling interests as a component of stockholders’ equity on the consolidated balance sheets and separately as net loss attributable to non-controlling interests on the consolidated statement of operations and comprehensive income.
Estimates	Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Significant estimates made by management include: i) the determination of the allowance for loan losses; (ii) the fair values of securities and the reporting unit to which goodwill has been assigned during the annual goodwill impairment test; (iii) the cash surrender value of bank owned life insurance; and (iv) the determination of whether the amount of deferred tax assets will more likely than not be realized. Management believes that these estimates are appropriate. Actual results could differ from these estimates.
Income Recognition, Interest	Interest income is generally recognized on the accrual basis using the interest method. Non-refundable loan origination fees, net of direct costs of originating or acquiring loans, as well as loan purchase premiums and discounts, are deferred and amortized over the term of the related loans as adjustments to interest income using the level yield method. Purchase premiums and discounts on debt securities are amortized as adjustments to interest income over the estimated lives of the securities using the level yield method.
Income Recognition, Fees	Brokerage and advisory activities include brokerage commissions and advisory fees. Brokerage commissions earned are related to the dollar amount of trading volume of customers’ transactions. Commissions and related clearing expenses are recorded on a trade-date basis as securities transactions occur. Advisory fees are derived from investment advisory fees and account administrative services. Investment advisory fees are recorded as earned on a pro rata basis over the term of the contracts, based on a percentage of the average value of assets managed during the period. These fees are assessed and collected at least quarterly. Account administrative fees are charged to customers for the maintenance of their accounts and are earned and collected on a quarterly basis. Fiduciary activities fee income is recognized as earned on a pro rata basis over the term of contracts. Card servicing fees include credit card issuance and credit and debit card interchange fees. Credit card issuance fees are generally recognized over the period in which the cardholders are entitled to use the cards. Interchange fees are recognized when earned. Trade finance servicing fees, which primarily include commissions on letters of credit, are generally recognized over the service period on a straight line basis. Deposits and services fees include service charges on deposit accounts, fees for banking services provided to customers including wire transfers, overdrafts and non-sufficient funds. Revenue from these sources is generally recognized in accordance with published deposit account agreements for customer accounts or when fixed and determinable per contractual agreements. Loan-level derivative income is generated from back-to-back derivative transactions with commercial loan clients and with brokers. The Company earns a fee upon inception of the back-to-back derivative transactions, corresponding to the spread between a wholesale rate and a retail rate.
Earnings Per Share	Earnings per Share Basic earnings per share is computed by dividing net income available to common stockholders by the weighted-average number of common shares outstanding during each period. Unvested shares of restricted stock are excluded from the basic earnings per share computation.
Stock-based Compensation	Stock-based CompensationThe Company may grant share-based compensation and other related awards to its non-employee directors, officers, employees and certain consultants. Compensation cost is measured based on the estimated fair value of the award at the grant date and recognized in earnings as an increase in additional paid in capital on a straight -line basis over the requisite service period or vesting period. The fair value of the unvested shares of restricted stock and restricted stock units is based on the market price of the Company’s Class A common stock at the date of the grant. The fair value of performance share units at the grant date is based on estimated fair values using an option pricing model.
Advertising Expenses	Advertising ExpensesAdvertising expenses are expensed as incurred, except for media production costs which are expensed upon the first airing of the advertisement, and are included in other noninterest expenses.
Voluntary and Involuntary Early Retirement Plan Expenses and other Staff Reduction Costs	Voluntary and Involuntary Early Retirement Plan Expenses and other Staff Reduction Costs The Company accounts for voluntary and involuntary early retirement plan expenses and other staff reduction costs by establishing a liability for costs associated with the exit or disposal activity, including severance and other related costs, when the liability is incurred, rather than when we commit to an exit plan. In 2021, salaries and employment benefits include $3.6 million of severance expenses, mainly in connection with the departure of our Chief Operating Officer in the second quarter of 2021, and the elimination of various support functions and other actions during the year in connection with the Company’s ongoing transformation and efficiency improvement efforts.
Offering Expenses	Offering ExpensesSpecific, non-reimbursable, incremental costs directly attributable to a proposed or actual securities offerings are deferred and charged against the gross proceeds of the offering.
Cash and Cash Equivalents	Cash and Cash Equivalents The Company has defined as cash equivalents those highly liquid instruments purchased with an original maturity of three months or less and include cash and cash due from banks, federal funds sold and deposits with banks.
Securities	Securities The Company classifies its investments in securities as debt securities available for sale, debt securities held to maturity and equity securities with readily determinable fair value not held for trading. Securities classified as debt securities available for sale are carried at fair value with unrealized gains and losses included in accumulated other comprehensive income (“AOCI”) or accumulated other comprehensive loss (“AOCL”) in stockholders’ equity on an after-tax basis. Equity securities with readily determinable fair value not held for trading primarily consists of mutual funds carried at fair value with unrealized gains and losses included in earnings. Equity securities were classified as available for sale at December 31, 2018 in accordance with GAAP. Securities classified as debt securities held to maturity are securities the Company has both the ability and intent to hold until maturity and are carried at amortized cost. Investments in stock issued by the Federal Reserve and Federal Home Loan Bank of Atlanta (“FHLB”) are stated at their original cost, which approximates their realizable value. Realized gains and losses from sales of securities are recorded on the trade date and are determined using the specific identification method. Securities purchased or sold are recorded on the consolidated balance sheets as of the trade date. Receivables and payables to and from clearing organizations relating to outstanding transactions are included in other assets or other liabilities. At December 31, 2021 and 2020 securities receivables amounted to $1.5 million and $1.9 million, respectively. At December 31, 2021, securities payable related to pending settlement of purchases amounted to $25.2 million. We had no securities payable at December 31, 2020. The Company considers an investment in debt securities to be impaired when a decline in fair value below the amortized cost basis is other-than-temporary. When an investment in debt securities is considered to be other-than-temporarily impaired, the cost basis of the individual debt security is written down through earnings by an amount that corresponds to the credit component of the other-than-temporary impairment. The amount of the other-than-temporary impairment that corresponds to the noncredit component of the other-than-temporary impairment is recorded in AOCI and is associated with debt securities which the Company does not intend to sell and it is more likely than not that the Company will not be required to sell the debt securities prior to the recovery of its fair value.
Loans Held for Sale, at Lower of Cost or Fair Value	Loans Held for Sale, at Lower of Cost or Fair Value Loans originated for investment are transferred into the held for sale classification at the lower of carrying amount or fair value, when they are specifically identified for sale and a formal plan exists to sell them. Mortgage Loans Held for Sale, at Fair Value
Loans Held for Investment	Loans Held for Investment Loans represent extensions of credit which the Company has the intent and ability to hold for the foreseeable future or until maturity or payoff. These extensions of credit consist of commercial real estate loans, or CRE loans, (including land acquisition, development and construction loans), owner occupied real estate loans, single-family residential loans, commercial loans, loans to financial institutions and acceptances, and consumer loans. Amounts included in the loan portfolio are stated at the amount of unpaid principal, reduced by unamortized net deferred loan fees and origination costs and an allowance for loan losses. Unamortized deferred loan origination costs , net of deferred fees, and premiums paid on purchased indirect consumer loans, amounted to $16.9 million and $15.5 million at December 31, 2021 and 2020, respectively. A loan is placed in nonaccrual status when management believes that collection in full of the principal amount of the loan or related interest is in doubt. Management considers that collectability is in doubt when any of the following factors are present, among others: (1) there is a reasonable probability of inability to collect principal, interest or both, on a loan for which payments are current or delinquent for less than ninety days; or (2) when a required payment of principal, interest or both, is delinquent for ninety days or longer, unless the loan is considered well secured and in the process of collection in accordance with regulatory guidelines. Once a loan to a single borrower has been placed in nonaccrual status, management reviews all loans to the same borrower to determine their appropriate accrual status. When a loan is placed in nonaccrual status, accrual of interest and amortization of net deferred loan fees or costs are discontinued, and any accrued interest receivable is reversed against interest income. Payments received on a loan in nonaccrual status are generally applied to its outstanding principal amount, unless there are no doubts on the full collection of the remaining recorded investment in the loan. When there are no doubts on the full collection of the remaining recorded investment in the loan, and there is sufficient documentation to support the collectability of that amount, payments of interest received may be recorded as interest income. A loan in nonaccrual status is returned to accrual status when none of the conditions noted when first placed in nonaccrual status are currently present, none of its principal and interest is past due, and management believes there are reasonable prospects of the loan performing in accordance with its terms. For this purpose, management generally considers there are reasonable prospects of performance in accordance with the loan terms when at least six months of principal and interest payments or principal curtailments have been received, and current financial information of the borrower demonstrates that the borrower has the capacity to continue to perform into the near future. The total outstanding principal amount of a loan is reported as past due thirty days following the date of a missed scheduled payment, based on the contractual terms of the loan. Loans which have been modified because the borrowers were experiencing financial difficulty and the Company, for economic or legal reasons related to the debtors’ financial difficulties, granted a concession to the debtors that it would not have otherwise considered, are accounted for as troubled debt restructurings (“TDR”).
Allowance for Loan Losses	Allowance for Loan Losses The allowance for loan losses (“ALL”) represents an estimate of the current amount of principal that is probable the Company will be unable to collect given facts and circumstances as of the evaluation date, and includes amounts arising from loans individually and collectively evaluated for impairment. These estimated amounts are recorded through a provision for loan losses charged against income. Management periodically evaluates the adequacy of the ALL to maintain it at a level believed reasonable to provide for recognized and unrecognized but inherent losses in the loan portfolio. The Company uses the same methods used to determine the ALL to assess any reserves needed for off-balance sheet credit risks such as unfunded loan commitments and contingent obligations on letters of credit. These reserves for off-balance sheet credit risks are presented in the liabilities section in the consolidated balance sheets. The Company develops and documents its methodology to determine the ALL at the portfolio segment level. The Company determines its loan portfolio segments based on the type of loans it carries and their associated risk characteristics. The Company’s loan portfolio segments are: Real Estate, Commercial, Financial Institutions, Consumer and Other. Loans in these portfolio segments have distinguishing borrower needs and differing risks associated with each product type. Real estate loans include commercial loans secured by real estate properties. Commercial loans secured by non-owner occupied real estate properties are generally granted to finance the acquisition or operation of commercial real estate properties, with terms similar to the properties’ useful lives or the operating cycle of the businesses. The main source of repayment of these real estate loans is derived from cash flows or conversion of productive assets and not from the income generated by the disposition of the property held as collateral. The main repayment source of loans granted to finance land acquisition, development and construction projects is generally derived from the disposition of the properties held as collateral, with the repayment capacity of the borrowers and any guarantors considered as alternative sources of repayment. Commercial loans correspond to facilities established for specific business purposes such as financing working capital and capital improvements projects and asset-based lending, among others. These may be loan commitments, uncommitted lines of credit to qualifying customers, short term (one year or less) or longer term credit facilities, and may be secured, unsecured or partially secured. Terms on commercial loans generally do not exceed five years, and exceptions are documented. Commercial loans secured by owner-occupied real estate properties are generally granted to finance the acquisition or operation of commercial real estate properties, with terms similar to the properties’ useful lives or the operating cycle of the businesses. The main source of repayment of these commercial real estate loans is derived from cash flows and not from the income generated by the disposition of the property held as collateral. Commercial loans to borrowers in similar businesses or products with similar characteristics or specific credit requirements are generally evaluated under a standardized commercial credit program. Commercial loans outside the scope of those programs are evaluated on a case by case basis, with consideration of any exposure under an existing commercial credit program. Loans to financial institutions and acceptances are facilities granted to fund certain transactions classified according to their risk level, and primarily include trade financing facilities through letters of credits, bankers’ acceptances, pre- and post-export financing, and working capital loans, among others. Loans in this portfolio segment are generally granted for terms not exceeding three years and on an unsecured basis under the limits of an existing credit program, primarily to large financial institutions in Latin America which the Company believes are of high quality. Prior to approval, management also considers cross-border and portfolio limits set forth in its programs and credit policies. Consumer and other loans are retail open-end and closed-end credits extended to individuals for household, family and other personal expenditures. These loans include loans to individuals secured by their personal residence, including first mortgage, home equity and home improvement loans as well as revolving credit card agreements. In addition, consumer and other loans, include purchased indirect lending loans we purchase from time to time from third parties. Because these loans generally consist of a large number of relatively small-balance, homogeneous loans for each type, their risks are generally evaluated collectively. An individual loan is considered impaired when it is probable that the Company will be unable to collect all amounts due, including both principal and interest, according to the contractual terms of the loan agreement. The Company generally considers as impaired all loans in nonaccrual status, and other loans classified in accordance with an internal risk grading system exceeding a defined threshold when it is probable that an impairment exists and the amount of the potential impairment is reasonably estimable. To determine when it is probable that an impairment exists, the Company considers the extent to which a loan may be inadequately protected by the current net worth and paying capacity of the borrower or any guarantor, or by the current value of the collateral. When a loan is considered impaired, the potential impairment is measured as the excess of the carrying value of the loan over the present value of expected future cash flows at the measurement date, or the fair value of the collateral in the case where the loan is considered collateral-dependent. If the amount of the present value of the loan’s expected future cash flows exceeds the loan’s carrying amount, the loan is still considered impaired but no impairment is recorded. The present value of an impaired loan results from estimating its future cash flows, discounted at the loan’s effective interest rate. In the case of loans considered collateral-dependent, which are generally certain real estate loans for which repayment is expected to be provided solely by the operation or sale of the underlying collateral, the potential impairment is measured based on the fair value of the asset pledged as collateral. The ALL on loans considered TDR is generally determined by discounting the restructured cash flows by the original effective interest rate on the loan. Loans that do not meet the criteria of an individually impaired loan are collectively evaluated for impairment. These loans include large groups of smaller homogeneous loan balances, such as loans in the consumer and other loan portfolio segment, and all other loans that have not been individually identified as impaired. This group of collective loans is evaluated for impairment based on measures of historical losses associated with loans within their respective portfolio segments adjusted by a variety of qualitative factors. These qualitative factors incorporate the most recent data reflecting current economic conditions, industry performance trends or obligor concentrations within each portfolio segment, among other factors. Other adjustments may be made to the allowance for loans collectively evaluated for impairment based on any other pertinent information that management considers may affect the estimation of the ALL, including a judgmental assessment of internal and external influences on credit quality that are not fully reflected in historical loss or their risk rating data. The measures of historical losses and the related qualitative adjustments are updated quarterly and semi-annually, respectively, to incorporate the most recent loan loss data reflecting current economic conditions. Loans to borrowers that are domiciled in foreign countries, primarily loans in the Consumer and Financial Institutions portfolio segments, are also evaluated for impairment by assessing the probability of additional losses arising from the Company’s exposure to transfer risk. The Company defines transfer risk exposure as the possibility that a loan obligation cannot be serviced in the currency of payment (U.S. Dollars) because the borrower’s country of origin may not have sufficient available currency of payment or may have put restraints on its availability, such as currency controls. To determine an individual country’s transfer risk probability, the Company assigns numerical values corresponding to the perceived performance of that country in certain macroeconomic, social and political factors generally considered in the banking industry for evaluating a country’s transfer risk. A defined country’s transfer risk probability is assigned to that country based on an average of the individual scores given to those factors, calculated using an interpolation formula. The results of this evaluation are also updated semi-annually.
Transfers of Financial Assets	Transfers of Financial Assets Transfers of financial assets are accounted for as sales or purchases when control over the assets has been surrendered by the transferor. Control over transferred assets is deemed to be surrendered when the assets have been isolated from the transferor, the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and the transferor does not maintain effective control over the transferred assets.
Debt Modification	Debt ModificationsDebt modifications or restructures, which are not considered a TDR, are accounted for as modifications if the terms of the new debt and original instrument are not considered substantially different. The debt is not considered substantially different when the present value of cash flows under the terms of the new debt instrument are less than 10% different from the present value of remaining cash flows under the terms of the original instrument. If the new debt is considered substantially different, the original debt is derecognized and the new debt is recorded at fair value, with any prepayment penalty being amortized over the life of the new borrowing. If the new debt is considered substantially different, the original debt is derecognized with any prepayment penalty recorded as a loss on debt extinguishment as a component of noninterest income.
Premises and Equipment, Net	Premises and Equipment, Net Premises and equipment are stated at cost, less accumulated depreciation and amortization. Depreciation is computed on the straight-line basis over the estimated useful lives of the related assets. Repairs and maintenance are charged to operations as incurred; renewals, betterments and interest during construction are capitalized. Gains or losses on sales of premises and equipment are recorded as noninterest income at the date of sale. The Company leases various premises for bank branches under operating leases. The leases have varying terms, with most containing renewal options and annual increases in base rents. Leasehold improvements are amortized over the remaining term of the lease.
Mortgage Servicing Rights	Mortgage Servicing Rights The Company recognizes as an asset the rights to service mortgage loans (“MSRs”), either when the mortgage loans are sold to third parties and the associated servicing rights are retained or when servicing rights are obtained from acquisitions. These MSRs are initially recorded at fair value. The Company has elected to subsequently measure all MSRs at fair value. MSRs are reported on the consolidated balance sheets in the “Other assets” section, with changes to the fair value recorded as other noninterest income in the consolidated statements of operations and comprehensive income. At December 31, 2021, MSRs totaled $0.6 million. There were no MSRs at December 31, 2020.
Bank Owned Life Insurance	Bank Owned Life Insurance Bank owned life insurance policies (“BOLI”) are recorded at the cash surrender value of the insurance contracts, which represent the amount that may be realizable under the contracts, at the consolidated balance sheet dates. Changes to the cash surrender value are recorded as other noninterest income in the consolidated statements of operations.
Income Taxes	Income Taxes Deferred income tax assets and liabilities are determined using the balance sheet method. Under this method, the resulting net deferred tax asset is determined based on the future tax consequences attributable to differences between the financial statement carrying amount of existing assets and liabilities and their respective tax basis. The effect of changes in tax laws or rates is recognized in results in the period that includes the legislation enactment date. A valuation allowance is established against the deferred tax asset to the extent that management believes that it is more likely than not that any tax benefit will not be realized. Income tax expense is recognized on the periodic change in deferred tax assets and liabilities at the current statutory rates. The results of operations of the Company and the majority of its wholly owned subsidiaries are included in the consolidated federal income tax return of the Company and its subsidiaries as members of the same consolidated tax group.
Goodwill	Goodwill Goodwill represents the excess of consideration paid over the fair value of the net assets of a savings bank acquired in 2006 and the Cayman Bank in 2019. Goodwill is not amortized but is reviewed for potential impairment at the reporting unit level on an annual basis in the fourth quarter, or on an interim basis if events or circumstances indicate a potential impairment. As part of its testing, the Company may elect to first assess qualitative factors to determine whether it is more likely than not that the fair value of the reporting unit is less than its carrying amount (“Step 0”). If the results of Step 0 indicate that more likely than not the reporting unit’s fair value is less than its carrying amount, the Company determines the fair value of the reporting unit relative to its carrying amount, including goodwill (“Step 1”). The Company may also elect to bypass Step 0 and begin with Step 1. If the fair value of the reporting unit exceeds its carrying amount, goodwill of the reporting unit is considered not impaired. However, if the carrying amount of the reporting unit exceeds its fair value, an additional procedure must be performed (“Step 2”). In Step 2, the implied fair value of the reporting unit’s goodwill is compared to the carrying amount of goodwill allocated to that reporting unit. An impairment loss is recorded to the extent that the carrying amount of goodwill exceeds its implied fair value at the measurement date.
Securities Sold Under Agreements to Repurchase	Securities Sold Under Agreements to Repurchase Securities sold under agreements to repurchase are classified as secured borrowings and are reflected at the amount of cash received in connection with the transaction.
Derivative Instruments	Derivative Instruments Derivative instruments are recognized on the consolidated balance sheets as other assets or other liabilities, at their respective fair values. The accounting for changes in the fair value of a derivative instrument is dependent upon whether the derivative has been designated and qualifies as part of a hedging relationship. For derivative instruments that have not been designated and qualified as hedging relationships, the change in their fair value is recognized in current period earnings. For derivative instruments that are designated and qualify as cash flow hedges, the effective portion of the gain or loss on the derivative instruments is initially recognized as a component of AOCI or AOCL, and subsequently reclassified into earnings in the same period during which the hedged transactions affect earnings. The ineffective portion of the gain or loss, if any, is recognized immediately in earnings. The Company has designated certain derivatives as cash flow hedges. Management periodically evaluates the effectiveness of these hedges in offsetting the fluctuations in cash flows due to changes in benchmark interest rates. The Company also enters into interest rate swaps to provide commercial loan clients the ability to swap from a variable interest rate to a fixed rate. The Company enters into a floating-rate loan with a customer with a separately issued swap agreement allowing the customer to convert floating payments of the loan into a fixed interest rate. To mitigate risk, the Company will generally enter into a matching agreement with a third party to offset the exposure on the customer agreement. These swaps are not considered to be qualified hedging relationships and therefore, all unrealized gain or loss is recorded as part of other noninterest income.
Fair Value Measurement	Fair Value Measurement Financial instruments are classified based on a three-level valuation hierarchy required by GAAP. The valuation hierarchy is based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date. The three levels are defined as follows: Level 1 Inputs to the valuation methodology are quoted prices in active markets for identical assets or liabilities. Level 1 assets and liabilities may include debt and equity securities that are traded in an active exchange market, as well as certain U.S. securities that are highly liquid and are actively traded in over-the-counter markets. Level 2 Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets and liabilities. Level 2 assets and liabilities include debt securities with quoted prices that are traded less frequently than exchange traded instruments which value is determined by using a pricing model with inputs that are observable in the market or can be derived principally from, or corroborated by, observable market data. This category generally may include U.S. government and U.S. Government Sponsored Enterprise mortgage backed debt securities and corporate debt securities. Level 3 Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Level 3 assets and liabilities may include financial instruments whose value is determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires significant management judgment or estimation. A financial instrument’s categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The valuation of debt securities available for sale, equity securities not held for trading, and derivative instruments is performed through a monthly pricing process using data provided by generally recognized providers of independent data pricing services (the “Pricing Providers”). These Pricing Providers collect, use and incorporate descriptive market data from various sources, quotes and indicators from leading broker dealers to generate independent and objective valuations. The fair value of bank-owned life insurance policies is based on the cash surrender values of the policies as reported by the insurance companies. The valuation techniques and the inputs used in our consolidated financial statements to measure the fair value of our recurring Level 2 financial instruments consider, among other factors, the following: • Similar securities actively traded which are selected from recent market transactions; • Observable market data which includes spreads in relationship to LIBOR, swap curve, and prepayment speed rates, as applicable. • The captured spread and prepayment speed is used to obtain the fair value for each related security. On a quarterly basis, the Company evaluates the reasonableness of the monthly pricing process for the valuation of debt securities available for sale and equity securities not held for trading and derivative instruments. This evaluation includes challenging a random sample of the different types of securities in the investment portfolio as of the end of the quarter selected. This challenge consists of obtaining from the Pricing Providers a document explaining the methodology applied to obtain their fair value assessments for each type of investment included in the sample selection. The Company then analyzes in detail the various inputs used in the fair value calculation, both observable and unobservable (e.g., prepayment speeds, yield curve benchmarks, spreads, delinquency rates). Management considers that the consistent application of this methodology allows the Company to understand and evaluate the categorization of its investment portfolio. The methods described above may produce a fair value calculation that may differ from the net realizable value or may not be reflective of future fair values. Furthermore, while the Company believes its valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of its financial instruments could result in different estimates of fair value at the reporting date. Level 3 Valuation Techniques Mortgage Servicing Rights MSRs are initially and subsequently measured at fair value, with changes in fair value recorded as part of noninterest income. The Company estimates the fair value of MSRs through the use of prevailing market participants assumptions and market participant valuation processes. This valuation is periodically tested and validated against other thrid-party firm valuations.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements Issued and Adopted New Guidance on Leases In December 2018, the Financial Accounting Standards Board (“FASB”) issued amendments to new guidance issued in February 2016 for the recognition and measurement of all leases. The amendments address certain lessor’s issues associated with: (i) sales taxes and other similar taxes collected from lessees, (ii) certain lessor costs, and (iii) recognition of variable payments for contracts with lease and nonlease components. The new guidance on leases issued in February 2016 requires lessees to recognize a right-of-use asset (“ROUA”) and a lease liability for most leases within the scope of the guidance. There were no significant changes to the guidance for lessors. The Company early adopted this standard on January 1, 2021 using the modified retrospective transition approach. Upon adoption of this standard, the Company recorded an ROUA and a lease liability of $54.5 million and $55.0 million, respectively. At December 31, 2021, ROUA and the corresponding lease liability were $141.1 million and $136.6 million, respectively. The Company determines if an arrangement is or contains a lease at the inception of the contract. Operating lease ROUAs and liabilities are recognized at the inception date based on the present value of lease payments over the lease term. At lease inception, when the rate implicit in each lease is not readily available, the Company is required to apply an incremental borrowing rate to calculate the ROUA and lease liability. The incremental borrowing rate is based on factors including the lease term and various market rates. Additionally, the Company also considers lease renewal options reasonably certain of exercise for purposes of determining the lease term. The new leasing standard provides several optional expedients in transition. The Company elected certain practical expedients, which allows the Company to not reassess prior conclusions on lease classification, embedded leases and initial indirect costs. The Company elected to exclude short-term leases up to 12 months from the recognition of right-of-use assets and lease liabilities. Additionally, the Company elected to separate lease and non-lease cost and accounts for them separately. Targeted Improvements to Accounting for Hedging Activities In August 2017, the FASB issued targeted amendments to the guidance for recognition, presentation and disclosure of hedging activities. These targeted amendments expand and refine hedge accounting for both nonfinancial and financial risk components and align the recognition and presentation of the effects of the hedging instrument and the hedged item in the financial statements. The amendments also simplify the application of hedge accounting guidance. In June 2020, the FASB amended the effective date of the new guidance on hedging. This guidance is effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years for public business entities. For all other entities, the amendments are effective for fiscal years beginning after December 15, 2020, and interim periods within fiscal years beginning after December 15, 2021. The adoption of this guidance in the first quarter of 2021 did not have an effect on the Company’s consolidated financial statements. Issued and Not Yet Adopted Facilitation of the Effects of Reference Rate Reform on Financial Reporting On March 12, 2020, the FASB issued amendments to guidance applicable to contracts, hedging relationships, and other transactions affected by that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. These amendments provide optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. The expedients and exceptions provided by the amendments do not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022, except for hedging relationships existing as of December 31, 2022, that an entity has elected certain optional expedients for and that are retained through the end of the hedging relationship. The amendments also allows entities to make a one-time election to sell, transfer, or both sell and transfer debt securities classified as held to maturity that reference a rate affected by reference rate reform and that are classified as held to maturity before January 1, 2020. These amendments are effective for all entities as of March 12, 2020 through December 31, 2022. During 2021, the Company completed its assessment of all third-party-provided products, services, and systems that would be affected by any changes to references to LIBOR, including changes to all relevant systems. Beginning in January 2022, the Company started referencing new loans and other products, including loan-level derivatives to the Secured Overnight Financing Rate (“SOFR”). The Company expects to begin migrating identified existing loans and derivative contracts from LIBOR to SOFR gradually during 2022. New Guidance on Accounting for Credit Losses on Financial Instruments In June 2016, the FASB issued the new guidance on accounting for current expected credit losses on financial instruments (“CECL.”) The new guidance introduces an approach based on expected losses to estimate credit losses on various financial instruments, including loans. It also modifies the impairment model for available-for-sale debt securities and provides for a simplified accounting model for purchased financial assets with credit deterioration since their origination. In November 2018, the FASB issued amendments to pending new guidance on CECL to, among other things, align the implementation date for private companies’ annual financial statements with the implementation date for their interim financial statements. Prior to the issuance of these amendments, the guidance on accounting for CECL was effective for private companies for fiscal years beginning after December 15, 2020, and interim periods within fiscal years beginning after December 15, 2021. These amendments are effective for fiscal years beginning after December 15, 2021, and interim periods within those fiscal years, for private companies. In November 2019, the FASB amended the effective date of the new guidance on CECL. Previously, the amendments and related new guidance on CECL was effective for fiscal years beginning after December 15, 2021, and interim periods within fiscal to those years, for private companies. The new guidance on CECL is now effective for fiscal years beginning after December 15, 2022 and interim periods within those years. Early adoption is still permitted. The new guidance on CECL is effective for fiscal years beginning after December 15, 2019, and interim periods within those years, for public companies. The Company formed a working group in 2021 with the intention of preparing for full adoption. As an EGC, the Company currently plans to adopt the new guidance on CECL in its consolidated financial statements for the year ending December 31, 2023, or earlier in the event the Company ceases to be an EGC.
Subsequent Events	Subsequent EventsThe effects of significant subsequent events, if any, have been recognized or disclosed in these consolidated financial statements.
Fair Value of Financial Instruments	The fair value of a financial instrument represents the price that would be received from its sale in an orderly transaction between market participants at the measurement date. The best indication of the fair value of a financial instrument is determined based upon quoted market prices. However, in many cases, there are no quoted market prices for the Company’s various financial instruments. As a result, the Company derives the fair value of the financial instruments held at the reporting period-end, in part, using present value or other valuation techniques. Those techniques are significantly affected by management’s assumptions, the estimated amount and timing of future cash flows and estimated discount rates included in present value and other techniques. The use of different assumptions could significantly affect the estimated fair values of the Company’s financial instruments. Accordingly, the net realized values could be materially different from the estimates presented below. The following methods and assumptions were used to estimate the fair value of each class of financial instruments for which it is practicable to estimate that value: • Because of their nature and short-term maturities, the carrying values of the following financial instruments were used as a reasonable estimate of their fair value: cash and cash equivalents, interest earning deposits with banks, variable-rate loans with re-pricing terms shorter than twelve months, demand and savings deposits, short-term time deposits and other borrowings. • The fair value of loans held for sale, debt and equity securities, bank owned life insurance and derivative instruments, are based on quoted market prices, when available. If quoted market prices are unavailable, fair value is estimated using the pricing process described in Note 19. • The fair value of commitments and letters of credit is based on the assumption that the Company will be required to perform on all such instruments. The commitment amount approximates estimated fair value. • The fair value of fixed-rate loans, advances from the FHLB, senior notes and junior subordinated debentures are estimated using a present value technique by discounting the future expected contractual cash flows using the current rates at which similar instruments would be issued with comparable credit ratings and terms at the measurement date. • The fair value of long-term time deposits, including certificates of deposit, is determined using a present value technique by discounting the future expected contractual cash flows using current rates at which similar instruments would be issued at the measurement date.
