Restructuring Activities The Company continues to work on better aligning its operating structure and resources with its business activities. 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 transitioning 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, the Company recorded estimated contract termination and related costs of approximately of $7.1 million in 2022. The Company currently expects to incur additional contract termination costs in connection with the implementation of this agreement that cannot be reasonably determined at this time. In 2022 and 2021, the Company recorded staff reduction costs of approximately $3.0 million and $3.6 million, respectively. In 2022, staff reductions costs include severance expenses, mainly in connection with the restructuring of business lines and the elimination of certain support functions during the year. In 2021, staff reduction costs included severance expenses related to i) closure of the Company’s New York City loan production office (the “NY LPO”) in the second quarter of 2021, ii) outsourcing the internal audit function during the second quarter of 2021, and iii) elimination of various other support positions throughout 2021, including the Company’s Chief Operating Officer (“COO”) stepping down from his position on June 30, 2021. Severance costs are recorded as part of “salaries and employees benefits expense” in the Company’s consolidated statement of operations and comprehensive (loss) income. Other restructuring expenses in 2022 and 2021 include: (i) consulting, legal and other professional fees of $3.6 million and $1.7 million, respectively. mainly related to the engagement with our new technology provider, in 2022, and primarily in connection with our capital optimization efforts and related transactions, and the engagement with our new technology provider, in 2021; (ii) lease impairment charges of $1.6 million in 2022 and $0.8 million 2021, related to the closing of a branch in Pembroke Pines, Florida in 2022, and in connection with the closure of the loan production office in New York in 2021, recorded in “occupancy and equipment expense” in the Company’s consolidated statement of operations and comprehensive income; and (iii) branch closure expenses of $0.5 million in 2021 related to the lease termination of a branch in Fort Lauderdale, Florida, and (iv) digital transformation expenses of $0.4 million in 2021. Optimizing Capital Structure Subordinated Notes . On March 9, 2022, the Company completed a $30.0 million offering of subordinated notes with a 4.25% fixed-to-floating rate and due on March 15, 2032 (the “Subordinated Notes”). See Note 10-Subordinated Notes, for details. Senior Notes. In June 2020, the Company completed a $60.0 million offering of 5.75% senior notes due 2025. See Note 9-Senior Notes, for details. Stock Repurchases . On February 14 and February 21, 2020, the Company entered into two privately negotiated transactions to repurchase shares of nonvoting Class B common stock. In December 2020, the Company completed a modified Dutch auction tender offer to purchase, for cash, up to $50 million of shares of its Class B common stock. In March 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 January 2022, the Company’s Board of Directors authorized a new repurchase program to repurchase up to $50 million of its shares of Class A common stock (the “New Common Stock Repurchase Program”). Also, in January 2022, the Company announced the completion of the Class A Common Stock Repurchase Program, previously authorized in September 2021. Lastly, in May 2022, the Company announced the completion of the New Common Stock Repurchase Program, previously authorized in January 2022. In 2022 and 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 2022 and 2021. See Note 18-Stockholders’ Equity for details on all stock repurchases. Clean-Up Merger . In November 2021, the Company’s shareholders 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 18-Stockholders’ Equity for details on the Clean-Up Merger. Dividends . In each of the four quarters of 2022, the Company’s Board of Directors declared a cash dividend of $0.09 per share of the Company’s Class A common stock. 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. See Note 18-Stockholders’ Equity for details on all dividends declared. Wholly-owned Subsidiaries Mergers On August 2, 2022, the Company completed an intercompany transaction of entities under common control, pursuant to which the Company’s wholly owned subsidiary, Amerant Florida Bancorp Inc. (“Amerant Florida”), merged with and into the Company, with the Company as sole survivor (the “Amerant Florida Merger”). In connection with the Amerant Florida Merger, the Company assumed all assets and liabilities of Amerant Florida, including its direct ownership of the Bank, the common capital securities issued by the 5 trust subsidiaries, and the junior subordinated debentures issued by Amerant Florida and related agreements. The Amerant Florida Merger had no impact to the Company’s consolidated financial condition and results of operations. See Note 11- Junior Subordinated Debentures Held By Trust Subsidiaries for additional information on the common capital securities issued by the five trust subsidiaries, and the junior subordinated debentures. In March 2021, the Bank and Amerant Trust, N.A, a non-depository trust company (“Amerant Trust”), received authorization to merge Amerant Trust with and into the Bank, with the Bank as sole survivor. The Company completed the merger of Amerant Trust with and into the Bank on April 1, 2021. Changes in Ownership Interest in Amerant Mortgage At December 31, 2022 and 2021, the Company had an 80% and 51% ownership interest in Amerant Mortgage, respectively. On March 31, 2022, the Company contributed $1.5 million in cash to Amerant Mortgage, increasing its ownership interest to 57.4% as of March 31, 2022 from 51% as of December 31, 2021. In addition, in the three months ended June 30, 2022, the Company increased its ownership interest in Amerant Mortgage to 80% from 57.4% at March 31, 2022. This change was the result of: (i) two former principals of Amerant Mortgage surrendering their interest in Amerant Mortgage to the Company, when they became full time employees of the Bank (the “Transfer of Subsidiary Shares From Noncontrolling Interest”), and (ii) an additional contribution made by the Company of $1 million, in cash, to Amerant Mortgage in the three months ended June 30, 2022. As a result of the Transfer of Subsidiary Shares From Noncontrolling Interest, in the year ended December 31, 2022, the Company reduced its Additional Paid-in Capital by a total of $1.9 million with a corresponding increase to the equity attributable to Noncontrolling Interest. 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. Amerant SPV Investments The Company, through Amerant SPV, has invested in equity and non-equity instruments issued by 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 the equity investment, in November 2021, Gerald P. Plush, our Company’s Chairman, President & CEO, was appointed to Marstone’s Board of Directors as one of its seven individual members. In this role, Mr. Plush does not have individual power to control or direct the operations of Marstone. The Company’s equity investment in Marstone represents less than 5% of its voting power. In addition, the Company considers it does not have a variable interest in Marstone. At December 31, 2022, the Company’s equity and non-equity investments in Marstone amount to $2.5 million and $1.3 million, respectively ($2.5 million and $1 million, respectively, in 2021). In October 2021, the Company invested $2.5 million in an equity instrument issued by Raistone Financial Corp (“Raistone”), a financial technology solutions provider launched in 2017 that offers working capital financing solutions. This equity investment represents less than 5% of Rainstone’s voting power. In addition, the Company considers it does not have a variable interest in Rainstone. There were no additional investments in Raistone in 2022. 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. At December 31, 2022 the investment in the Fund amounts to $1.2 million (none in 2021). These investments in Marstone, Raistone and the Fund are recorded at their original cost and are included in the Company’s consolidated balance sheet in other assets. The Company reviews these investments periodically for deterioration. At December 31, 2022 and 2021, the Company considers these investments are not deteriorated and did not record an impairment charge as a result. Employee Stock Purchase Plan On June 8, 2022, the shareholders of the Company approved the Amerant Bancorp Inc. 2021 Employee Stock Purchase Plan (the “ESPP” or the “Plan”). The purpose of the Plan is to provide eligible employees of the Company and its designated subsidiaries with the opportunity to acquire a stock ownership interest in the Company on favorable terms and to pay for such acquisitions through payroll deductions. All named executive officers, and all other executive officers of the Company who were eligible as of the enrollment deadline for the first offering period elected to participate in the Plan. See Note 14-Incentive Compensation and Benefit Plans for more details on the ESPP. 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, including significant changes in interest rates, 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, 2022, PPP loan balances were not significant. 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 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 that had been modified under these programs totaled $1.1 billion as of December 31, 2021 and 2020. As of December 31, 2022, there were no loans under the deferral and/or forbearance options. 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 were not considered troubled debt restructurings, or TDRs. Hurricane Ian In late September 2022, Hurricane Ian (the “Hurricane”) impacted several countries in the Caribbean, and the U.S., causing significant damage, and disrupting businesses in several regions, including several South and Central Florida counties in which the Company does business, including the Tampa Bay, Port Charlotte, Naples and Orlando markets and their surrounding areas. On September 28, 2022, the Hurricane made landfall near Cayo Costa in southwestern Florida, as a powerful Category 4 hurricane on the Saffir-Simpson scale, bringing intense winds and heavy rainfall and storm surges, causing catastrophic wind and water damage to infrastructure, homes and businesses in southwestern Florida, including the city of Tampa where we operate a loan production office. The Company has not identified any significant impacts to the loan portfolio of the Company deemed to be located in the areas that may have been meaningfully impacted by the Hurricane, and the Company has not identified any significant impact to the collateral securing the loans in the exposed loan portfolio in the region. The Company has been in contact with the impacted borrowers and has performed site visits as well. In addition, the Company has been actively involved in efforts to support the recovery of the communities negatively impacted by the Hurricane. The Hurricane had no material negative impact to the Company’s operations in Tampa, FL in the year ended December 31, 2022. 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, a 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 benefited from this extended transition period since it became a publicly traded company. As of December 31, 2022, the Company determined that it was deemed a large accelerated filer effective as of that date, based on the aggregate worldwide market value of its voting and non-voting common stock held by the Company’s non-affiliates as of the last business day of the second quarter of 2022. Consequently, the Company determined that it no longer qualified as an EGC as of December 31, 2022 and, therefore, was unable to continue to benefit from any extended transition period for complying with new or revised accounting standards as of that date. See discussion below of recently adopted accounting pronouncements as a result of this transition. See sections below for more details. Significant Accounting Policies 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 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 (loss) income. At December 31, 2022 and 2021, non-controlling interest in Amerant Mortgage was 20% and 49%, respectively. In 2021 and throughout the first quarter of 2022, non-controlling interest in Amerant Mortgage was 49%. 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 credit losses; (ii) the fair values of securities; (iii) the cash surrender value of bank owned life insurance; (iv) the determination of whether the amount of deferred tax assets will more likely than not be realized; and (v) the determination of estimated contract termination costs. Management believes that these estimates are appropriate. Actual results could differ from these estimates. The COVID-19 pandemic has impacted the global and U.S. economic activity since March 2020, and has and may continue to materially and negatively impact supply chains, labor supply and certain industries in which our customers operate. 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 had or 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 businesses have reopened, generally, and economic activity accelerated in 2022, 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. The Company considers there are significant uncertainties in the assessment and quantification of the full extent of the damage caused by the Hurricane, as well as its long-term impact on economic activity in the region. The damages are meaningful and have, at least in the short-term, had a material adverse impact on regional economic activity, as reflected by, among other things, the slow-down in sales and service activity, primarily in the hospitality and related industries. Regional employment levels are also expected to decrease at least in the short-term. The speed at which the State of Florida and other federal and local governments can restore infrastructure and services throughout the impacted region, will be a critical variable in determining the extent of the impact on economic activity. Furthermore, the Hurricane severely damaged or destroyed buildings, homes and other infrastructure, impacting the value of such properties, some of which may serve as collateral to our loans. While our collateral is generally insured, the value of such insured structures, as well as other structures unaffected by the Hurricane, may be significantly impacted. Although some of the impact of the Hurricane, including its short-term impact on economic activity, may be offset by recovery and reconstruction activity and the influx of Federal emergency funds and private insurance proceeds, it is still uncertain the amount of Federal and private insurance money to be received and whether such transfers will significantly offset the negative economic, fiscal and demographic impact of the Hurricane. Since there is significant uncertainty with respect to the full extent of the negative impacts due to the nature of the Hurricane, the Company’s estimates with respect to the loan portfolio potentially impacted and the reserve for credit losses, are based on judgment and subject to change as conditions evolve. The Company will continue to carefully assess and review the exposure of the portfolios to hurricane-related factors, economic trends and their effect on credit quality and that assessment and review could result in additional provision for credit losses required in future periods. In 2022, noninterest expenses include $7.1 million of estimated contract termination costs associated with third party vendors resulting from the Company’s transition to our new technology provider. Contract termination costs represent estimated expenses to terminate contracts before the end of their terms, and are recognized when the Company terminates a contract in accordance with its terms, generally considered the time when the Company gives written notice to the counterparty within the notification period contractually established. Contract termination costs also include expenses associated with the abandonment of existing capitalized projects which are no longer expected to be completed as a result of a contract termination. Changes to initial estimated expenses to terminate contracts resulting from revisions to timing or the amount of estimated cash flows are recognized in the period of the changes. Reclassifications In 2022, advertising expenses are presented separately in the Company’s consolidated statement of operations and comprehensive (loss) income. Prior to 2022, these expenses were presented as a component of other noninterest expenses in the Company’s consolidated statement of operations and comprehensive (loss) income. Also, in 2022, loan- level derivative expenses are presented separately in the Company’s consolidated statement of operations and comprehensive (loss) income. Prior to 2022, these expenses were presented as a component of professional and other services fees in the Company’s consolidated statement of operations and comprehensive (loss) income. 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 stock 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. 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 and debit card interchange fees and other fees. 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 deriv

In the years ended December 31, 2022 and 2021, proceeds from sales, redemptions and calls, gross realized gains, gross realized losses of debt securities available for sale were as follows: Years Ended December 31 (in thousands) 2022 2021 Proceeds from sales, redemptions and calls of debt securities available for sale $ 61,399 $ 114,923 Gross realized gains 73 4,307 Gross realized losses (2,522) (33) Realized (loss) gain, net $ (2,449) $ 4,274 The Company’s investment in debt securities available for sale with unrealized losses aggregated by the length of time that individual securities have been in a continuous unrealized loss position, are summarized below: December 31, 2022 Less Than 12 Months 12 Months or More Total (in thousands) Number of Securities Estimated Unrealized Number of Securities Estimated Unrealized Estimated Unrealized U.S. government sponsored enterprise debt securities 250 $ 292,595 $ (22,315) 108 $ 96,986 $ (21,351) $ 389,581 $ (43,666) Corporate debt securities 50 203,516 (13,374) 14 72,190 (12,825) 275,706 (26,199) U.S. government agency debt securities 92 88,056 (4,976) 104 240,668 (37,838) 328,724 (42,814) Municipal bonds 3 1,656 (75) — — — 1,656 (75) U.S. treasury securities 1 1,996 (1) — — — 1,996 (1) Collateralized Loan Obligations 1 4,774 (226) — — — 4,774 (226) 397 $ 592,593 $ (40,967) 226 $ 409,844 $ (72,014) $ 1,002,437 $ (112,981) December 31, 2021 Less Than 12 Months 12 Months or More Total (in thousands) Number of Securities Estimated Unrealized Number of Securities Estimated Unrealized Estimated Unrealized U.S. government sponsored enterprise debt securities 29 $ 54,562 $ (1,434) 59 $ 25,526 $ (1,004) $ 80,088 $ (2,438) Corporate debt securities 8 52,672 (259) 3 10,286 (670) 62,958 (929) U.S. government agency debt securities 35 200,051 (1,177) 69 52,109 (1,193) 252,160 (2,370) 72 $ 307,285 $ (2,870) 131 $ 87,921 $ (2,867) $ 395,206 $ (5,737) At December 31, 2022 and 2021, the Company held certain debt securities issued or guaranteed by the U.S. government and U.S. government-sponsored entities and agencies. The Company evaluates these securities for credit losses by reviewing current market conditions, extent and nature of changes in fair value, credit ratings, default and delinquency rates and current analysts’ evaluations. Based on this evaluation, the Company believes these issuers present little credit risk. The Company considers the decline in fair value on these debt securities is attributable to changes in interest rates and investment securities markets, generally, and not credit quality. The Company does not intend to sell these debt securities and it is more likely than not that it will not be required to sell the securities before their anticipated recovery. As a result, the Company did not record an allowance for credit losses on these securities as of December 31, 2022. Investments in corporate debt available for sale as of December 31, 2022 include securities considered “investment-grade-quality” primarily issued by financial institutions, with a fair value of $258.8 million ($43.4 million at December 31, 2021), which had total unrealized losses of $24.1 million at that date ($0.3 million at December 31, 2021); and securities considered “non-investment-grade-quality” from issuers in the financial and technology industries, with a fair value of $16.9 million ($19.6 million at December 31, 2021), which had total unrealized losses of $2.1 million at that date ($0.6 million at December 31, 2021). Unrealized losses on corporate debt securities are attributable to changes in interest rates and investment securities markets, generally, and as a result, temporary in nature. Based on various qualitative and quantitative factors such as current market conditions, extent and nature of changes in fair value, credit ratings, default and delinquency rates, and current analysts’ evaluations, the Company considers these securities present little credit risk. The Company does not intend to sell these investments and it is more likely than not that it will not be required to sell these investments before their anticipated recovery. As a result, the Company did not record an allowance for credit losses on these securities as of December 31, 2022. There were no debt securities available for sale held by the Company considered delinquent on contractual payments as of December 31, 2022 and 2021, nor were there any securities placed on non-accrual status during the year ended December 31, 2022 and 2021.

The Company considers that all debt securities held to maturity issued or sponsored by the U.S. government are considered to be risk-free as they have the backing of the government. The Company considers there are not current expected credit losses on these securities and, therefore, did not record an ACL on any of its debt securities held to maturity as of December 31, 2022. The Company monitors the credit quality of held to maturity securities through the use of credit ratings. Credit ratings are monitored by the Company on at least a quarterly basis. As of December 31, 2022 and 2021, all held to maturity securities held by the Company were rated investment grade or higher. Contractual maturities Contractual maturities of debt securities at December 31, 2022 are as follows: Available for Sale Held to Maturity (in thousands) Amortized Estimated Amortized Estimated Within 1 year $ 9,311 $ 9,281 $ — $ — After 1 year through 5 years 74,994 71,231 6,480 3,848 After 5 years through 10 years 286,468 262,664 13,130 12,395 After 10 years 798,805 714,445 222,491 201,366 $ 1,169,578 $ 1,057,621 $ 242,101 $ 217,609 Actual maturities of debt securities available for sale and held to maturity may differ from contractual maturities because issuers may have the right to call or prepay obligations with or without prepayment penalties. b) Equity securities with readily available fair value not held for trading The Company had equity securities with readily available fair value not held for trading with an original cost of $12.7 million and $0.3 million, and fair value of $11.4 million and $0.3 million as of December 31, 2022 and 2021, respectively. These equity securities have no stated maturities. The Company recognized in earnings unrealized losses of $1.3 million and $0.6 million during the years ended December 31, 2022 and 2021, respectively, related to the change in fair value of equity securities with readily available fair value not held for trading. In addition, during 2021, the Company recognized in earnings a $42 thousand loss on the sale of a mutual fund with a fair value of $23.4 million at the time of the sale. In February 2023, the Company sold all of its equity securities with readily available fair value not held for trading and realized a loss on sale of approximately $0.2 million. c) Securities Pledged As of December 31, 2022 and 2021, the Company had $314.5 million and $142.8 million, respectively, in securities pledged as collateral.

Loans	Loans a) Loans held for investment Loans held for investment consist of the following loan classes: (in thousands) December 31, December 31, Real estate loans Commercial real estate Nonowner occupied $ 1,615,716 $ 1,540,590 Multi-family residential 820,023 514,679 Land development and construction loans 273,174 327,246 2,708,913 2,382,515 Single-family residential 1,102,845 661,339 Owner occupied 1,046,450 962,538 4,858,208 4,006,392 Commercial loans 1,381,234 965,673 Loans to financial institutions and acceptances 13,292 13,710 Consumer loans and overdrafts 604,460 423,665 Total loans held for investment, gross (1) $ 6,857,194 $ 5,409,440 _________________ (1) Excludes accrued interest receivable. 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 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 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. The Company provides equipment financing using a variety of loan and lease structures, as part of its commercial lending activities. These equipment loans and leases are originated under a white-label equipment financing solution launched in the second quarter of 2022. 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. Single-family residential and consumer and other loans are retail open-end and closed-end credits extended to individuals for household, family and other personal expenditures. Single-family and consumer 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. In the year ended December 31, 2022, the Company purchased $385.8 million in indirect consumer loans and $173.1 million in single-family residential loans. At December 31, 2022 and 2021, loans with an outstanding principal balance of $1.2 billion and $1.1 billion, respectively, were pledged as collateral to secure advances from the FHLB. The amounts in the table above include loans under syndication facilities for approximately $367.0 million and $373 million at December 31, 2022 and 2021, respectively, which include Shared National Credit facilities, or SNCs, and agreements to enter into credit agreements among other lenders (club deals), and other agreements. These loans are primarily designed for providing working capital to certain qualified domestic and international commercial entities meeting our credit quality criteria and concentration limits, and approved in accordance with credit policies. In addition, consumer loans and overdrafts in the table above include indirect consumer loans purchased totaling $433.3 million and $297.0 million at December 31, 2022 and 2021, respectively. International loans included above were $99.2 million and $99.6 million at December 31, 2022 and 2021, respectively, mainly single-family residential loans. These loans are net of collateral of cash, cash equivalents or other financial instruments totaling $6.3 million and $21.1 million as of December 31, 2022 and December 31, 2021, respectively. The age analysis of the loan portfolio by class as of December 31, 2022 is summarized in the following table: December 31, 2022 Total Loans, Loans Past Due (in thousands) Current Loans 30-59 60-89 Greater than Total Past Real estate loans Commercial real estate Nonowner occupied $ 1,615,716 $ 1,615,716 $ — $ — $ — $ — Multi-family residential 820,023 818,394 1,387 242 — 1,629 Land development and construction loans 273,174 273,174 — — — — 2,708,913 2,707,284 1,387 242 — 1,629 Single-family residential 1,102,845 1,098,310 3,140 150 1,245 4,535 Owner occupied 1,046,450 1,039,928 172 6,014 336 6,522 4,858,208 4,845,522 4,699 6,406 1,581 12,686 Commercial loans 1,381,234 1,373,042 1,523 475 6,194 $ 8,192 Loans to financial institutions and acceptances 13,292 13,292 — — — — Consumer loans and overdrafts 604,460 601,921 2,439 62 38 2,539 $ 6,857,194 $ 6,833,777 $ 8,661 $ 6,943 $ 7,813 $ 23,417 Nonaccrual status The following table presents the amortized cost basis of loans on nonaccrual status and loans past due over 90 days and still accruing as of December 31, 2022: (in thousands) Nonaccrual Loans With No Related Allowance Nonaccrual Loans With Related Allowance Total Nonaccrual Loans (1) Loans Past Due Over 90 Days and Still Accruing Real estate loans Commercial real estate Nonowner occupied $ 20,057 $ — $ 20,057 $ — Multi-family residential — — — — Single-family residential — 1,526 1,526 253 Owner occupied 5,936 334 6,270 — 25,993 1,860 27,853 253 Commercial loans 482 8,789 9,271 183 Consumer loans and overdrafts — 4 4 35 Total (1) $ 26,475 $ 10,653 $ 37,128 $ 471 _____________ (1) The Company did not recognize any interest income on nonaccrual loans during the year ended December 31, 2022.

(2) Remained current and in accrual status at each of the periods shown. (3) Excludes accrued interest receivable. As of December 31, 2021, loans held for sale at the lower of fair value or cost consisted of New York commercial real estate (“CRE”) loans. In 2022, the Company transferred the New York CRE loans held for sale to the loans held for investment category. Also, in 2022, the Company completed the sale of approximately $57.3 million in loans held for sale carried at the lower of fair value or cost related to the New York portfolio, at their par value. c) Concentration of risk While seeking diversification of our loan portfolio held for investment and held for sale, the Company is dependent mostly on the economic conditions that affect South Florida and the greater Houston and New York City areas, especially the five New York City boroughs. Diversification is managed through policies with limitations for exposure to individual or related debtors and for country risk exposure. d) Accrued interest receivable on loans

This TDR consisted of extending repayment terms and adjusting future periodic payments which resulted in no additional reserves. As of December 31, 2022, this relationship included two residential loans totaling $1.6 million and one commercial loan of $0.8 million, which were not modified (two residential loans totaling $1.4 million and one commercial loan of $0.8 million which were not modified at December 31, 2021). During 2020, the company charged off $1.9 million against the ACL associated with this commercial loan relationship. The Company believes the specific reserves associated with these loans, which total $0.1 million and $0.8 million at December 31, 2022 and 2021, respectively, are adequate to cover probable losses given current facts and circumstances.

Credit Risk Quality The sufficiency of the ACL is reviewed at least quarterly by the Chief Risk Officer and the Chief Financial Officer. The Board of Directors considers the ACL as part of its review of the Company’s consolidated financial statements. As of December 31, 2022 and 2021, the Company believes the ACL (ALL in 2021) to be sufficient to absorb expected credit losses in the loans portfolio in accordance with GAAP. Loans may be classified but not considered collateral dependent due to one of the following reasons: (1) the Company has established minimum dollar amount thresholds for individual assessment of expected credit losses, which results in loans under those thresholds being excluded from individual assessment of expected credit losses; and (2) classified loans may be considered in the assessment because the Company expects to collect all amounts due. 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 in the process of estimating expected credit losses. The Company utilizes an internal risk rating system to identify the risk characteristics of each of its loans, or group of homogeneous loans such as consumer loans. Internal risk ratings are updated on a continuous basis 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. Internal risk ratings are considered the most meaningful indicator of credit quality for commercial loans. Generally, internal risk ratings for commercial real estate loans and commercial loans with balances over $3 million are updated at least annually and more frequently if circumstances indicate that a change in risk rating may be warranted. For consumer loans, single-family residential loans and smaller commercial loans under $3 million, risk ratings are updated based on the loans past due status.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.

residential real estate and consumer loan portfolios is evaluated by considering the repayment performance of individual borrowers, and then classified on an aggregate or pool basis. Loan secured by real estate in these classes which have been past due 90 days or more, and 120 days or 180 days or more, are classified as Substandard and Loss, respectively. Beginning in 2022, unsecured consumer loans which become past due 90 days are charged- off (120 days previously). When the Company has documented that past due loans in these classes are well-secured and in the process of collection, then the loans may not be classified. Loan-To-Value and FICO scores are also an important indicator of credit quality for single-family residential loans and consumer loans. When loans are classified, loan-to-value is updated at least annually. FICO scores are typically at origination, except for a significant portion of indirect consumer loans which are updated at least quarterly.

The Company performs an individual evaluation as part of the process of calculating the allowance for credit losses related to these loans. The following table presents the amortized cost basis of collateral dependent loans related to borrowers experiencing financial difficulty by type of collateral as of December 31, 2022: Collateral Type (in thousands) Commercial Real Estate Residential Real Estate Other Total Specific Reserves Real estate loans Commercial real estate Nonowner occupied (1) $ 20,121 $ — $ — $ 20,121 $ — Owner occupied (2) 5,934 — — 5,934 — 26,055 — — 26,055 — Commercial loans (3) 1,998 — 6,401 8,399 5,179 Total $ 28,053 $ — $ 6,401 $ 34,454 $ 5,179 _________________ (1) Weighted-average loan-to-value was approximately 92.7% at December 31, 2022. (2) Weighted-average loan-to-value was approximately 62.7% at December 31, 2022. (3) Includes loans with no specific reserves totaling $0.5 million with a weighted-average loan-to-value of approximately 42%. Collateral dependent loans are evaluated on an individual basis for purposes for determining expected credit losses. For collateral-dependent loans where the borrower is experiencing financial difficulty and the Company expects repayment of the financial asset to be provided substantially through the operation or sale of the collateral, the ACL is measured based on the difference between the fair value of the collateral and the amortized cost basis of the loan as of the measurement date. When repayment is expected to be from the operation of the collateral, expected credit losses are calculated as the amount by which the amortized cost basis of the loan exceeds the present value of expected cash flows from the operation of the collateral. When repayment is expected to be from the sale of the collateral, expected credit losses are calculated as the amount by which the amortized cost basis of the loan exceeds the fair value of the underlying collateral less estimated costs to sell. The ACL may be zero if the fair value of the collateral at the measurement date exceeds the amortized cost basis of the loan. In the year ended December 31, 2022, the weighted-average loan-to-values related to existing owner-occupied and commercial collateral-dependent loans decreased approximately 16% and 22%, respectively, since December 31, 2021.

Debt Disclosure [Abstract]
Junior Subordinated Debentures Held by Trust Subsidiaries	Junior Subordinated Debentures Held by Trust Subsidiaries At December 31, 2022 and 2021, 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”). 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 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 Debentures issued to, each of the Trust Subsidiaries as of December 31, 2022 and 2021: December 31, 2022 December 31, 2021 (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 2022 and 2021, 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. This redemption reduced total cash and cash equivalents by $27.1 million, financial liabilities by $28.1 million, other assets by $3.4 million, and other liabilities by $2.2 million during the three months ended March 31, 2020. In addition, the Company recorded a charge of $0.3 million during the same period for the unamortized issuance costs. This redemption reduced the Company’s Tier 1 equity capital by a net amount of $24.7 million. LIBOR Cessation and Expected Replacement Rate The Trust Preferred Securities and the Debentures issued by the Company include calculations that are based on 3-month LIBOR. On March 15, 2022, the Adjustable Interest Rate (LIBOR) Act (the ‘LIBOR Act”) was signed into law. Under the LIBOR Act, on the first London banking day after June 30, 2023 (the “LIBOR Replacement Date”), a benchmark replacement recommend by the Federal Reserve will replace LIBOR in certain contracts, including those that contain no fallback provisions and other related aspects. The Federal Reserve issued its final regulations under the LIBOR Act. The final regulations: (i) address the applicability of the LIBOR Act to various LIBOR contracts, which include the Trust Preferred Securities and the Debentures, (ii) identify the benchmark replacements, (iii) include certain benchmark replacement conforming changes, (iv) address the issue of preemption and (v) provide other clarifications, definitions and information. Based on a review of the Trust Preferred Securities and the Debentures documents, these documents do not provide a replacement rate for 3-month LIBOR or include other fallback provisions which would apply on the LIBOR Replacement Date. Based on the U.K. Financial Conduct Authority’s current statements, it does not appear that a synthetic LIBOR benchmark will be applicable to the Trust Preferred Securities and Debentures. Accordingly, absent an amendment to the Trust Preferred Securities and Debenture documents, some other change in applicable law, rule, regulation, or some other development, on and after the LIBOR Replacement Date, 3-month CME term SOFR or 6-month CME Term SOFR (as defined in the regulations) as adjusted by the relevant spread adjustment of 0.26161%, shall be the benchmark replacement for 3-month LIBOR in the Trust Preferred Securities and Debentures documents, and all applicable benchmark replacement conforming changes as specified in the regulations will become an integral part of the Trust Preferred Securities and Debenture documents, without any action by any party. The Company will not seek to amend the Trust Preferred Securities and Debentures documents to reflect any other LIBOR benchmark replacement.

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, 2022 and 2021 the fair value of the Company’s derivative instruments was as follows: December 31, 2022 December 31, 2021 (in thousands) Other Assets Other Liabilities Other Assets Other Liabilities Interest rate swaps designated as cash flow hedges $ 167 $ 45 $ — $ 615 Interest rate swaps not designated as hedging instruments: Customers 603 66,439 18,858 1,923 Third party broker 66,439 603 1,923 18,858 67,042 67,042 20,781 20,781 Interest rate caps not designated as hedging instruments: Customers — 10,002 — 764 Third party broker 10,207 — 477 — 10,207 10,002 477 764 Mortgage derivatives not designated as hedging instruments: Interest rate lock commitments 727 — 581 — Forward contracts 107 71 31 38 834 71 612 38 $ 78,250 $ 77,160 $ 21,870 $ 22,198 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, 2022 and 2021, the Company had five interest rate swap contracts with notional amounts totaling $64.2 million, maturing in the third and fourth quarters of 2025 as of December 31, 2022 (maturing in the second half of 2022 as of December 31, 2021). In 2022, the Company had five interest rate swap contracts which matured. After these contracts matured, five new interest rate swap contracts were entered into in 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, 2022 and 2021 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 2022 and 2021, the Company recognized unrealized losses of $0.4 million and $0.9 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 (loss) income. As of December 31, 2022, the estimated net unrealized losses in accumulated other comprehensive expected to be reclassified into expense in the next twelve months amounted to $0.5 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 of 2022 and 2021 as a result of this amortization. As of December 31, 2022, the remaining cumulative net unrealized gains related to these interest rate swaps was $3.5 million. Derivatives Not Designated as Hedging Instruments Interest Rate Swaps At December 31, 2022 and 2021, the Company had 143 and 109 interest rate swap contracts with customers, respectively, with a total notional amount of $925.4 million and $595.4 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, 2022 and 2021, the Company had interest rate swap mirror contracts with third party brokers with similar terms. These instruments have maturities ranging from less than 1 to 14 years in 2022 (2 to 13 years in 2021). The Company enters 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, 2022 and 2021, we had four and two swap participation agreements with an aggregate notional amount of approximately $74.0 million and $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, 2022 and 2021, the fair value of swap participation agreements was not significant. Interest Rate Caps At December 31, 2022 and 2021, the Company had 19 interest rate cap contracts with customers with a total notional amounts of $448.8 million and $432.0 million, respectively. These instruments involve the Company making payments if an interest rate exceeds the agreed strike price. In addition, at December 31, 2022 and 2021, the Company had 16 and 9 interest rate cap mirror contracts with a third party broker with total notional amounts of $371.9 million and $190.7 million, respectively. These instruments have maturities ranging from less than 1 to 12 years in 2022 (less than 1 to 5 years in 2021). In April 2022, the Company entered into 4 interest rate cap contracts with various third-party brokers with total notional amounts of $140.0 million at December 31, 2022. These interest rate caps serve to partially offset changes in the estimated fair value of interest rate cap contracts with customers at December 31, 2022. Mortgage Derivatives The Company enters into interest rate lock commitments and forward sale contracts to manage the risk exposure in the mortgage banking area. At December 31, 2022 and 2021, the Company had interest rate lock commitments with notional amounts of $77.0 million and $17.9 million, respectively, and forward contracts with notional amounts of $17.0 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 2022 and 2021 , the change in the fair value of these instruments was $0.2 million and $0.6 million. These amounts were recorded as part of other noninterest income in the consolidated statements of operations and comprehensive (loss) 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, 2022 and 2021 there were $0.5 million and $2.0 million, respectively, in debt securities held for sale pledged as collateral to secure interest rate swaps designated as cash flow hedges, with a fair value of $45 thousand and $0.6 million, respectively. Additionally, the Company had cash held as collateral of $41.6 million for derivatives margin calls. See Note 2 “Interest Earning Deposits with Banks” for additional information about cash held as collateral. In addition, at December 31, 2021, there were $23.4 million in debt securities available for sale pledged as collateral to secure interest rate swaps with third-party brokers not designated as hedging instruments, with a fair value of $18.9 million. As of December 31, 2022, there were no collateral requirements related to interest rate swaps with third-party brokers not designated as hedging instruments.

Leases [Abstract]
Leases	Leases The Company leases certain premises and equipment under operating leases. The operating leases have remaining lease terms ranging from less than one year to 43 years, some of which have renewal options reasonably certain to be exercised and, therefore, have been reflected in the total lease term and used for the calculation of minimum payments required.

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, 2022 and 2021, the Company had accumulated net operating losses (“NOLs”) in the State of Florida of approximately $161.0 million and $166.5 million, respectively. These NOLs are carried forward for a maximum of 20 years or indefinitely, depending on the year generated, based on applicable Florida law. The deferred tax asset related to these NOLs at December 31, 2022 and 2021 is approximately $7.0 million and $7.2 million, respectively. A valuation allowance has been recorded against the state deferred tax asset as management believes it is more likely than not that the tax benefit will not be realized.

Equity [Abstract]
Stockholders’ Equity	Stockholders’ Equity (a) Amended and Restated Articles of Incorporation Clean-Up Merger In November 2021, the Company’s shareholders approved a clean-up merger, previously announced by the Company in September 2021, pursuant to which a subsidiary of the Company merged with and into the Company (the “Clean-up Merger”). 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 as 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, were 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. Pursuant to the amended and restated articles, the total number of authorized shares of stock of all classes is 300,000,000, consisting of the following classes: Class Number of Par Value Common Stock: Class A - voting common stock 225,000,000 $ 0.10 Class A - non-voting common stock 25,000,000 0.10 250,000,000 Preferred Stock 50,000,000 0.10 300,000,000 Common Stock The Class A voting common stock and the Class A non-voting common stock are identical in all respects except that the Class A non-voting common stock are not be entitled to vote on any matter (unless such a vote is required by applicable laws or Nasdaq regulations in a particular case). Preferred Stock The Board of Directors is authorized to provide for and designate, out of the authorized but unissued shares of Preferred Stock, one or more series of Preferred Stock and, with respect to each such series, to fix the number of shares, the price, dividend rates, rights, preferences, privileges and restrictions, including voting rights, of one or more series of preferred stock from time to time, without any vote or further action by the shareholders. 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, 2022 and December 31, 2021 were 33,815,161 and 35,883,320, respectively. On December 19, 2022, the Company announced that the Board of Directors authorized a new repurchase program pursuant to which the Company may purchase, from time to time, up to an aggregate amount of $25 million of its shares of Class A common stock (the “2023 Class A Common Stock Repurchase Program”). The 2023 Class A Common Stock Repurchase Program is effective from January 1, 2023 until December 31, 2023. On January 31, 2022, the Company announced that the Board of Directors authorized 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. Under the New Class A Common Stock Repurchase Program, the Company was able to repurchase shares of Class A common stock through open market purchases, by block purchase, in privately negotiated transactions or otherwise in compliance with Rule 10b-18 under the Exchange Act. The extent to which the Company was able to repurchase its shares of Class A 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 New Class A Common Stock Repurchase Program did not obligate the Company to repurchase any particular amount of shares of Class A common stock, and may have been suspended or discontinued at any time without notice. In 2022, the Company repurchased an aggregate of 1,602,887 shares of Class A common stock at a weighted average price of $31.14 per share, under the New Common Stock Repurchase Program. The aggregate purchase price for these transactions was approximately $49.9 million, including transaction costs. On May 19, 2022, the Company announced the completion of the New Common Stock Repurchase Program. 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 provided 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, the Company was able to repurchase shares of Class A common stock through open market purchases, by block purchase, in privately negotiated transactions or otherwise in compliance with Rule 10b-18 under the Exchange Act. The extent to which the Company was able to repurchase its shares of Class A 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 A Common Stock Repurchase Program did not obligate the Company to repurchase any particular amount of shares of Class A common stock, and may have been suspended or discontinued at any time without notice. In 2022 and 2021, the Company repurchased an aggregate of 652,118 shares and 893,394 shares, respectively, of Class A common stock at a weighted average price per share of $33.96 and $31.18, respectively, under the Class A Common Stock Repurchase Program. In 2022 and 2021, the aggregate purchase price for these transactions was approximately $22.1 million and $27.9 million, respectively, including transaction costs. On January 31, 2022, the Company announced the completion of 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. In 2022, 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 2022, 2021 and 2020. Therefore, the Company had no shares of common stock held in treasury stock at December 31, 2022 and 2021. Stock-Based Compensation Awards The Company grants, from time to time, stock-based compensation awards which are reflected as changes in the Company’s Stockholders’ equity. See Note 14 “Stock-Based Incentive Compensation Plan” for additional information about common stock transactions under the Company’s 2018 Equity Plan. c) Dividends On October 20, 2022, the Company’s Board of Directors declared a cash dividend of $0.09 per share of the Company’s Class A common stock.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies From time to time the Company and its subsidiaries may be exposed to loss contingencies. In the ordinary, course of business, those contingencies may include, known but unasserted claims, and legal / regulatory inquiries or examinations. The Company records these loss contingencies as a liability when the likehood of loss is probable and an amount or range of loss can be reasonably estimated. In the opinion of management, the Company maintains a liability that is in an estimated amount sufficient to cover said loss contingencies, if any, at the reporting dates. 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, 2022 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. Financial instruments whose contract amount represents off-balance sheet credit risk at December 31, 2022 are generally short-term and are as follows: (in thousands) Approximate Commitments to extend credit $ 1,165,701 Standby letters of credit 20,643 Commercial letters of credit 83 $ 1,186,427

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 and other relevant interest rate benchmarks that may become available from time to time, such as SOFR, 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 third-party firm valuations. There were no transfers in or out or level 3 in the years ended December 31, 2022, 2021 and 2020. 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, 2022 and 2021: December 31, 2022 (in thousands) Carrying Amount Quoted Significant Significant Total Write Downs Description Loans held for investment measured individually using the fair value of the collateral $ 30,158 $ — $ — $ 30,158 $ 3,851 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 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, 2022 and 2021. Collateral Dependent Loans Measured For Expected Credit Losses The carrying amount of collateral dependent loans is typically based on the fair value of the underlying collateral.The Company primarily uses third party appraisals to assist in measuring expected credit losses on collateral dependent 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 Company had no OREO balances as of December 31, 2022. 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 20 • 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, subordinated 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, 2022 December 31, 2021 (in thousands) Carrying Estimated Carrying Estimated Financial assets Debt securities held to maturity $ 242,101 $ 217,609 $ 118,175 $ 119,077 Loans 3,314,553 3,181,696 2,619,461 2,559,280 Financial liabilities Time deposits 1,119,510 1,099,294 1,048,078 1,057,759 Advances from the FHLB 906,486 873,852 809,577 819,268 Senior notes 59,210 58,755 58,894 63,214 Subordinated notes 29,284 28,481 — — Junior subordinated debentures 64,178 64,182 64,178 61,212

This valuation is periodically tested and validated against other third-party firm valuations. There were no transfers in or out or level 3 in the years ended December 31, 2022, 2021 and 2020. 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, 2022 and 2021: December 31, 2022 (in thousands) Carrying Amount Quoted Significant Significant Total Write Downs Description Loans held for investment measured individually using the fair value of the collateral $ 30,158 $ — $ — $ 30,158 $ 3,851 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 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, 2022 and 2021. Collateral Dependent Loans Measured For Expected Credit Losses The carrying amount of collateral dependent loans is typically based on the fair value of the underlying collateral.The Company primarily uses third party appraisals to assist in measuring expected credit losses on collateral dependent 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 Company had no OREO balances as of December 31, 2022. 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 20 • 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, subordinated 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, 2022 December 31, 2021 (in thousands) Carrying Estimated Carrying Estimated Financial assets Debt securities held to maturity $ 242,101 $ 217,609 $ 118,175 $ 119,077 Loans 3,314,553 3,181,696 2,619,461 2,559,280 Financial liabilities Time deposits 1,119,510 1,099,294 1,048,078 1,057,759 Advances from the FHLB 906,486 873,852 809,577 819,268 Senior notes 59,210 58,755 58,894 63,214 Subordinated notes 29,284 28,481 — — Junior subordinated debentures 64,178 64,182 64,178 61,212

Regulatory Matters

Regulatory Matters Disclosure [Abstract]
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, 2022 and 2021, the Bank could have paid dividends of $43.8 million and $97.0 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 by January 1, 2019. The Company and the Bank opted to not include the AOCI in computing regulatory capital. As of December 31, 2022, 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%. The Company’s capital conservation buffer at year end 2022 and 2021 was 4.4% and 6.6%, respectively, and therefore no regulatory restrictions exist under the applicable capital rules on dividends or discretionary bonuses or other payments. The Bank’s actual capital amounts and ratios are presented in the following table: Actual Minimums Required for Capital Adequacy Purposes Regulatory Minimums to be Well Capitalized (in thousands, except percentages) Amount Ratio Amount Ratio Amount Ratio December 31, 2022 Total capital ratio $ 923,113 12.10 % $ 610,149 8.00 % $ 762,686 10.00 % Tier 1 capital ratio 837,970 10.99 % 457,612 6.00 % 610,149 8.00 % Tier 1 leverage ratio 837,970 9.27 % 361,655 4.00 % 452,069 5.00 % Common equity tier 1 (CET1) capital ratio 837,970 10.99 % 343,209 4.50 % 495,746 6.50 % December 31, 2021 Total capital ratio $ 957,852 14.94 % $ 512,780 8.00 % $ 640,976 10.00 % Tier 1 capital ratio 886,301 13.83 % 384,585 6.00 % 512,780 8.00 % Tier 1 leverage ratio 886,301 11.84 % 299,466 4.00 % 374,332 5.00 % CET1 capital ratio 886,301 13.83 % 288,439 4.50 % 416,634 6.50 % The Company’s actual capital amounts and ratios are presented in the following table: Actual Minimums Required for Capital Adequacy Purposes Regulatory Minimums To be Well Capitalized (in thousands, except percentages) Amount Ratio Amount Ratio Amount Ratio December 31, 2022 Total capital ratio $ 947,505 12.39 % $ 611,733 8.00 % $ 764,666 10.00 % Tier 1 capital ratio 833,078 10.89 % 458,799 6.00 % 611,733 8.00 % Tier 1 leverage ratio 833,078 9.18 % 363,130 4.00 % 453,913 5.00 % CET1 capital ratio 772,105 10.10 % 344,100 4.50 % 497,033 6.50 % December 31, 2021 Total capital ratio $ 934,512 14.56 % $ 513,394 8.00 % $ 641,742 10.00 % Tier 1 capital ratio 862,962 13.45 % 385,045 6.00 % 513,394 8.00 % Tier 1 leverage ratio 862,962 11.52 % 299,746 4.00 % 374,683 5.00 % CET1 capital ratio 801,907 12.50 % 288,784 4.50 % 417,133 6.50 % The Company adopted CECL effective as of January 1, 2022. The Company has not elected to apply an available three-year transition provision to its regulatory capital computations as a result of its adoption of CECL in 2022. Mortgage Banking 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, 2022 and 2021, Amerant Mortgage had a Lender Adjusted Net Worth of approximately $7.7 million and $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 has demonstrated compliance with all financial eligibility requirements as of December 31, 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 Mortgage 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 Mortgage 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, potential dilutive instruments consisted of unvested shares of restricted stock and restricted stock units totaling 248,750 mainly related to the Company’s IPO in 2018. As of December 31, 2022 and 2021, 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, in those periods, 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. 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.

(“Amerant Florida”), merged with and into the Company, with the Company as sole survivor (the “Amerant Florida Merger”). In connection with the Amerant Florida Merger, the Company assumed all assets and liabilities of Amerant Florida, including its direct ownership of the Bank, the common capital securities issued by the 5 trust subsidiaries, and the junior subordinated debentures issued by Amerant Florida and related agreements. The Amerant Florida Merger had no impact to the Company’s consolidated financial condition and results of operations.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Restructuring Activities	Restructuring Activities The Company continues to work on better aligning its operating structure and resources with its business activities. 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 transitioning 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, the Company recorded estimated contract termination and related costs of approximately of $7.1 million in 2022. The Company currently expects to incur additional contract termination costs in connection with the implementation of this agreement that cannot be reasonably determined at this time. In 2022 and 2021, the Company recorded staff reduction costs of approximately $3.0 million and $3.6 million, respectively. In 2022, staff reductions costs include severance expenses, mainly in connection with the restructuring of business lines and the elimination of certain support functions during the year. In 2021, staff reduction costs included severance expenses related to i) closure of the Company’s New York City loan production office (the “NY LPO”) in the second quarter of 2021, ii) outsourcing the internal audit function during the second quarter of 2021, and iii) elimination of various other support positions throughout 2021, including the Company’s Chief Operating Officer (“COO”) stepping down from his position on June 30, 2021. Severance costs are recorded as part of “salaries and employees benefits expense” in the Company’s consolidated statement of operations and comprehensive (loss) income.
Employee Stock Purchase Plan	Employee Stock Purchase Plan On June 8, 2022, the shareholders of the Company approved the Amerant Bancorp Inc. 2021 Employee Stock Purchase Plan (the “ESPP” or the “Plan”). The purpose of the Plan is to provide eligible employees of the Company and its designated subsidiaries with the opportunity to acquire a stock ownership interest in the Company on favorable terms and to pay for such acquisitions through payroll deductions. All named executive officers, and all other executive officers of the Company who were eligible as of the enrollment deadline for the first offering period elected to participate in the Plan. See Note 14-Incentive Compensation and Benefit Plans for more details on the ESPP.
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 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 (loss) income. At December 31, 2022 and 2021, non-controlling interest in Amerant Mortgage was 20% and 49%, respectively. In 2021 and throughout the first quarter of 2022, non-controlling interest in Amerant Mortgage was 49%.
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 credit losses; (ii) the fair values of securities; (iii) the cash surrender value of bank owned life insurance; (iv) the determination of whether the amount of deferred tax assets will more likely than not be realized; and (v) the determination of estimated contract termination costs. Management believes that these estimates are appropriate. Actual results could differ from these estimates. The COVID-19 pandemic has impacted the global and U.S. economic activity since March 2020, and has and may continue to materially and negatively impact supply chains, labor supply and certain industries in which our customers operate. 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 had or 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 businesses have reopened, generally, and economic activity accelerated in 2022, 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. The Company considers there are significant uncertainties in the assessment and quantification of the full extent of the damage caused by the Hurricane, as well as its long-term impact on economic activity in the region. The damages are meaningful and have, at least in the short-term, had a material adverse impact on regional economic activity, as reflected by, among other things, the slow-down in sales and service activity, primarily in the hospitality and related industries. Regional employment levels are also expected to decrease at least in the short-term. The speed at which the State of Florida and other federal and local governments can restore infrastructure and services throughout the impacted region, will be a critical variable in determining the extent of the impact on economic activity. Furthermore, the Hurricane severely damaged or destroyed buildings, homes and other infrastructure, impacting the value of such properties, some of which may serve as collateral to our loans. While our collateral is generally insured, the value of such insured structures, as well as other structures unaffected by the Hurricane, may be significantly impacted. Although some of the impact of the Hurricane, including its short-term impact on economic activity, may be offset by recovery and reconstruction activity and the influx of Federal emergency funds and private insurance proceeds, it is still uncertain the amount of Federal and private insurance money to be received and whether such transfers will significantly offset the negative economic, fiscal and demographic impact of the Hurricane. Since there is significant uncertainty with respect to the full extent of the negative impacts due to the nature of the Hurricane, the Company’s estimates with respect to the loan portfolio potentially impacted and the reserve for credit losses, are based on judgment and subject to change as conditions evolve. The Company will continue to carefully assess and review the exposure of the portfolios to hurricane-related factors, economic trends and their effect on credit quality and that assessment and review could result in additional provision for credit losses required in future periods.
Reclassification	ReclassificationsIn 2022, advertising expenses are presented separately in the Company’s consolidated statement of operations and comprehensive (loss) income. Prior to 2022, these expenses were presented as a component of other noninterest expenses in the Company’s consolidated statement of operations and comprehensive (loss) income. Also, in 2022, loan- level derivative expenses are presented separately in the Company’s consolidated statement of operations and comprehensive (loss) income. Prior to 2022, these expenses were presented as a component of professional and other services fees in the Company’s consolidated statement of operations and comprehensive (loss) income.
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. 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 stock 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.
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 and debit card interchange fees and other fees. 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.
Stock-based Compensation	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 stock 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 2022 and 2021, salaries and employment benefits include $3.0 million and $3.6 million of severance expenses mainly in connection with the Company’s ongoing restructuring activities.
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.
Loan-level derivative expenses	Loan-level derivative expenses Loan-level derivative expenses are incurred in back-to-back derivative transactions with commercial loan clients and with brokers. The Company pays a fee upon inception of the back-to-back derivative transactions, corresponding to the spread between a wholesale rate and a retail rate.
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. 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, 2022 and 2021.
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. 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, 2022 and 2021 securities receivables included in other assets amounted to $0.9 million and $1.5 million, respectively. At December 31, 2022 and 2021, securities payable related to purchases pending settlement and included in other liabilities amounted to $0.3 million and $25.2 million, respectively. For debt securities available for sale, the Company evaluates whether: (i) the fair value of the securities is less than the amortized costs basis; (ii) it intends to sell, or it is more likely than not that it will be required to sell, the security before recovery of its amortized cost basis, and (iii) the decline in fair value has resulted from credit losses or other factors. The Company estimates credit losses on debt securities available for sale using a discounted cash flow model. The present value of an impaired debt security results from estimating future cash flows that are expected to be collected, discounted at the debt security’s effective interest rate. The Company develops its estimates about cash flows expected to be collected and determines whether a credit loss exists, generally using information about past events, current conditions, reasonable and supportable forecasts and other qualitative factors including the extent to which fair value is less than amortized cost basis, adverse conditions specifically related to the security, industry or geographic area, changes in conditions of any collateral underlying the securities, changes in credit ratings, failure of the issuer to make scheduled payments, among other qualitative factors specific to the applicable security. If a credit loss exists, the Company records an allowance for the credit losses, limited to the amount by which the fair value is less than the amortized cost basis. The Company recognizes in AOCI/AOCL any impairment that has not been recorded through an allowance for credit losses.
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. When the Company determines that a formal plan to sell loans in this category no longer exists, the Company reclassifies these loans to loans held for investment at their carrying value at the date of the transfer, with the loans carrying value becoming their new basis. Any resulting difference between the loans unpaid principal amount and their carrying value is amortized through earning for the remainder lives of the loans.
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 loans unamortized costs reduced by an allowance for credit losses if any. The unamortized cost of a loan consists of its unpaid principal balance, unamortized premiums, discounts and deferred loan origination fees and costs, net of amounts previously charged off. Unamortized premiums, discounts and deferred loan origination costs, including premiums paid on purchases of indirect consumer loans as well as purchases of single-family residential loans and other loans, amounted to $17.8 million and $16.9 million at December 31, 2022 and 2021, 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 considered troubled debt restructurings (“TDR”). In 2020, the Company began offering customized loan payment relief options as a result of the impact of the COVID-19 pandemic, including deferral and forbearance options. Consistent with accounting and regulatory guidance, temporary modifications granted under these programs are not considered TDRs. See
Allowance for Loan Losses	Allowance for Credit Losses (ACL) In 2022, the Company adopted Accounting Standards Codification Topic 326 - Financial Instruments - Credit Losses (ASC Topic 326), which replaced the incurred loss methodology for estimated probable loan losses with an expected credit loss methodology that is referred to as the current expected credit loss (“CECL”) methodology. The ACL is a valuation account that is deducted from the amortized cost basis of financial assets carried at their amortized cost, including loans held for investment and debt securities held to maturity, to present the net amount that is expected to be collected throughout the life of the financial asset. The estimated ACL is recorded through a provision for credit losses charged against operations. Management periodically evaluates the adequacy of the ACL to maintain it at a level it believes to be reasonable. The Company uses the same methods used to determine the ACL 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 ACL consists of two components: an asset-specific component for estimating credit losses for individual loans that do not share similar risk characteristics with other loans; and a pooled component for estimating credit losses for pools of loans that share similar risk characteristics. The ACL for the pooled component is derived from an estimate of expected credit losses primarily using an expected loss methodology that incorporates risk parameters such as probability of default (“PD”) and loss given default (“LGD”) which are derived from various vendor models and/or internally developed model estimation approaches for smaller homogenous loans. PD is projected in these models or estimation approaches using economic scenarios, whose outcomes are weighted based on the Company’s economic outlook and are developed to incorporate relevant information about past events, current conditions, and reasonable and supportable forecasts. For commercial loans above $3 million, LGD is typically derived from the Company’s own loss experience based on specific risk characteristics. For commercial real estate loans, the LGD is derived from vendor models using property and loan risk characteristics. The estimation of the ACL for pools of loans that share similar risk characteristics involves inputs and assumptions, many of which are derived from vendor and internally-developed models. These inputs and assumptions include, among others, the selection, evaluation and measurement of the reasonable and supportable forecast scenarios, PD and LGD which requires management to apply a significant amount of judgment and involves a high degree of estimation uncertainty. The ACL estimation process applies an economic forecast scenario or a composite of scenarios based on management's judgment and expectations around the current and future macroeconomic outlook. Expected credit losses are estimated over the contractual term of the loans, adjusted for expected prepayments when appropriate. The contractual term of a loan excludes expected extensions, renewals, and modification under certain conditions. For smaller-balance homogeneous pooled loans with similar risk characteristics such as collateral type and loan purpose (e.g., residential, small business lending under $3 million, consumer and land loans), other modeling techniques are used. These include modeling that relies upon observable inputs such as historical or average loss rates by year of loan origination (i.e.,vintage) and prepayment considerations for future expected contractual loan outstanding balances. For the smaller-balance homogenous pooled loan segments, the quantitative estimates of expected credit losses are then adjusted to incorporate considerations of current trends and conditions that are not captured in the quantitative credit loss estimates through the use of qualitative or environmental factors. The measurement of expected credit losses on these loan segments is influenced by macro-economic conditions. Expected credit losses on loans to borrowers that are domiciled in foreign countries, primarily loans in the Consumer and Financial Institutions portfolios are generally estimated by assessing the any available cash or other types of collateral, and the probability of losses arising from the Company’s exposure to those collateral assets. Loans in these portfolio are generally fully collateralized with cash, securities and other assets and, therefore, generally have no expected credit losses. Commercial real estate, commercial and financial institution loans are charged off against the ACL when they are considered uncollectable. These loans are considered uncollectable when a loss becomes evident to management, which generally occurs when the following conditions are present, among others: (1) a loan or portions of a loan are classified as “loss” in accordance with the internal risk and credit monitoring grading system; (2) a collection attorney has provided a written statement indicating that a loan or portions of a loan are considered uncollectible; and (3) the carrying value of a collateral-dependent loan exceeds the appraised value of the asset held as collateral. Consumer and other retail loans are charged off against the ACL at the earlier of (1) when management becomes aware that a loss has occurred, or (2) beginning effective as of and for the year ended December 31, 2022, when closed-end retail loans become past due 90 days (120 days previously) or open-end retail loans become past due 180 days from the contractual due date. For open and closed-end retail loans secured by residential real estate, any outstanding loan balance in excess of the fair value of the property, less cost to sell, is charged off no later than when the loan is 180 days past due from the contractual due date. Consumer and other retail loans may not be charged off when management can clearly document that a past due loan is well secured and in the process of collection such that collection will occur regardless of delinquency status in accordance with regulatory guidelines applicable to these types of loans. With respect to TDRs, a change to the ACL is generally not recorded upon modification since the effect of these TDRs is already included in the ACL given the measurement methodologies used to estimate the ACL. From time to time, the Company modifies loans by providing principal forgiveness, the amount of the principal forgiveness is deemed to be uncollectible and, therefore, that portion of the loan is written off resulting in a reduction of the amortized cost basis and a corresponding adjustment to the ACL.
Accrued Interest Receivable	Accrued Interest ReceivableThe Company has elected to present accrued interest receivable related to loans, debt securities available for sale and held to maturity as part of other assets in the Company’s consolidated balance sheets. Therefore, accrued interest receivable is excluded from the amortized cost basis of loans, debt securities available for sale and held to maturity. The Company generally does not estimate an ACL on accrued interest receivable balances since uncollectible accrued interest is timely written off in accordance with the Company's accounting policies for non-accrual loans. Accrued interest receivable on nonaccrual loans is written off by reversing interest income.
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 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.
Leases	Leases The Company determines whether a contract is or contains a lease at inception. For leases with terms greater than twelve months under which the Company is lessee, right-of-use assets and lease liabilities are recorded at the commencement date. Lease liabilities are initially recorded based on the present value of future lease payments over the lease term. Right-of-use assets are initially recorded at the amount of the associated lease liabilities plus prepaid lease payments and initial direct costs, less any lease incentives received. The cost of short term leases is recognized on a straight line basis over the lease term. The lease term includes options to extend if the exercise of those options is reasonably certain and includes termination options if there is reasonable certainty the options will not be exercised. The Company uses its incremental borrowing rate based on the appropriate term and information available at commencement date in determining the present value of lease payments, unless an implicit rate is defined in the contract or is determinable, which is generally not the case. Leases are classified as financing or operating leases at commencement; generally, leases are classified as finance leases when effective control of the underlying asset is transferred. All the leases under which the Company is lessee are classified as operating leases. For operating leases, lease cost is recognized in earnings on a straight line basis over the lease terms.Variable lease costs are recognized in the period in which the obligation for those costs is incurred. Sublease income is recognized as a reduction to lease cost over a straight line basis over the lease terms. The Company provides equipment financing under sales-type and direct finance leases. These leases are carried at the aggregate of lease payments receivable and estimated residual value of the leased property, if applicable, less unearned income. Interest income is recognized over the term of the leases to achieve a constant periodic rate of return on the outstanding investment.
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 (loss) income. At December 31, 2022 and 2021, MSRs totaled $1.3 million and $0.6 million, respectively.
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 primarily 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. 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 and other relevant interest rate benchmarks that may become available from time to time, such as SOFR, 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 third-party firm valuations. There were no transfers in or out or level 3 in the years ended December 31, 2022, 2021 and 2020.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements Issued and Adopted New Guidance on Accounting for Credit Losses on Financial Instruments In 2022, the Company adopted ASC Topic 326 on CECL. The Company adopted the CECL guidance as of the beginning of the reporting period of adoption, January 1, 2022, using a modified retrospective approach for all its financial assets measured at amortized cost and off-balance sheet credit exposures. The following table reflects the impact of adopting CECL on the Company’s consolidated balance sheets: January 1, 2022 (in thousands) As Reported Under ASC 326 Pre-ASC 326 Adoption Impact of ASC 326 Adoption Assets Allowance for credit losses $ 88,573 $ 69,899 $ 18,674 Deferred tax assets, net 16,103 11,301 4,802 Liabilities Reserve for unfunded credit commitments 1,702 1,702 — Stockholder’s Equity Retained earnings 539,295 553,167 (13,872) Upon CECL adoption, the Company did not record an allowance for credit losses for off-balance sheet credit exposures and debt securities available for sale and held to maturity. See Note 3-Securities for more details on the determination of expected credit losses on debt securities available for sale and held to maturity. Issued and Not Yet Adopted New Guidance on Fair Value Hedges In March 2022, the Financial Accounting Standards Board (“FASB”) issued amended guidance to expand and clarify existing guidance on fair value hedge accounting of interest rate risk for portfolios of financial assets. The amendments clarify, among others, the “last-of-layer” method for making the fair value hedge accounting for these portfolios more accessible. The amendment also improves the last-of-layer concepts and expands them to nonprepayable financial assets, allowing more flexibility in the structure of derivatives used to hedge interest rate risk. The amended guidance is effective for public business entities for fiscal years beginning after December 15, 2022, and interim periods within those fiscal years. For all other entities, the amended guidance is effective for fiscal years beginning after December 15, 2023. The amended guidance is available for early adoption. The Company is in the process of reviewing this new guidance to determine whether it would have a material impact on the Company’s consolidated financial statements when adopted. New Guidance on Troubled Debt Restructurings In March 2022, the FASB issued guidance that eliminates the recognition and measurement guidance on troubled debt restructurings for creditors, and aligns it with existing guidance to determine whether a loan modification results in a new loan or a continuation of an existing loan. The new guidance also requires enhanced disclosures about certain loan modifications by creditors when a borrower is experiencing financial difficulty. The amended guidance is effective in periods beginning after December 15, 2022 using either a prospective or modified retrospective transition approach. Early adoption is permitted if an entity has already adopted the guidance on accounting for CECL. The Company is in the process of reviewing this new guidance to determine whether it would have a material impact on the Company’s consolidated financial statements when adopted. New Guidance for Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions On June 30, 2022, the FASB issued new guidance to improve fair value guidance for equity securities subject to contractual sale restrictions. These amendments clarify that a contractual restriction on the sale of an equity security is not considered part of the unit of account of the equity security and, therefore, is not considered in measuring fair value. The amendments also clarify that an entity cannot, as a separate unit of account, recognize and measure a contractual sale restriction. The amendments also require additional disclosures for equity securities subject to contractual sale restrictions. For public business entities, the amendments are effective for fiscal years beginning after December 15, 2023, and interim periods within those fiscal years. The Company is in the process of evaluating the impact of this guidance on its consolidated financial statements when 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.

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 20 • 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, subordinated 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.
