NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - UNAUDITED

September 30, 2022

Note 1    Basis of Presentation and Summary of Significant Accounting Policies

BankUnited, Inc. is a national bank holding company with one wholly-owned subsidiary, BankUnited, collectively, the Company. BankUnited, a national banking association headquartered in Miami Lakes, Florida, provides a full range of banking and related services to individual and corporate customers through 58 banking centers located in 12 Florida counties, 4 banking centers located in the New York metropolitan area, and 1 banking center located in Dallas, Texas at September 30, 2022. The Bank also offers certain commercial lending and deposit products through national platforms and regional wholesale banking offices.

The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X of the SEC. Accordingly, these do not include all of the information and footnotes required for a fair presentation of financial position, results of operations and cash flows in conformity with GAAP and should be read in conjunction with the Company’s consolidated financial statements and the notes thereto appearing in BKU’s Annual Report on Form 10-K for the year ended December 31, 2021 filed with the SEC. In the opinion of management, all adjustments, consisting of normal recurring adjustments, considered necessary for a fair presentation have been included. Operating results for the three and nine months ended September 30, 2022 are not necessarily indicative of the results that may be expected in future periods.

The Company has a single operating segment and thus a single reportable segment. While management monitors the revenue streams of its various business units, the business units serve a similar base of primarily commercial clients, providing a similar range of products and services, managed through similar processes and platforms. The Company’s chief operating decision maker makes company-wide resource allocation decisions and assessments of performance based on a collective assessment of the Company’s operations.

Accounting Estimates

In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, and expenses and disclosures of contingent assets and liabilities. Actual results could differ significantly from these estimates.

The most significant estimate impacting the Company's consolidated financial statements is the ACL.

New Accounting Pronouncements Adopted During the Nine Months Ended September 30, 2022

ASU No. 2020-06, Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity’s Own Equity (Subtopic 815-40). This ASU simplifies the accounting for convertible debt and convertible preferred stock by reducing the number of accounting models for these instruments, resulting in fewer embedded conversion features being separately recognized from the host contract. Additionally, this ASU revises the criteria for determining whether contracts in an entity's own equity meet the scope exception from derivative accounting, which will change the population of contracts that are recognized as assets or liabilities. The amendments in this ASU also revise certain aspects of the guidance on calculating earnings per share with respect to convertible instruments and instruments that may be settled in the entity's own shares. The Company adopted this ASU on January 1, 2022, with no material impact on the Company's consolidated financial position, results of operations, and cash flows.

ASU No. 2022-01, Fair Value Hedging—Portfolio Layer Method (Topic 815). This ASU expands the portfolio layer method of hedge accounting prescribed in ASU No. 2017-12 to allow multiple hedged layers of a single closed portfolio and to include portfolios of both prepayable and non-prepayable financial assets. This scope expansion is consistent with the FASB’s efforts to simplify hedge accounting and allows entities to apply the same accounting method to similar hedging strategies. The ASU also specifies eligible hedging instruments in a single-layer hedge, provides additional guidance on accounting and disclosure of hedge basis adjustments and specifies how hedge basis adjustments should be considered in determining credit losses for assets in the designated closed portfolio. This ASU is effective for public business entities for interim and annual periods in fiscal years beginning after December 15, 2022. The Company adopted this ASU upon its release in March 2022 with no material impact on the Company's consolidated financial position, results of operations, and cash flows.

ASU No. 2022-02, Financial Instruments—Credit Losses (Topic 326). This ASU eliminates the accounting guidance for TDRs by creditors in Subtopic 310-40, Receivables - Troubled Debt Restructurings by Creditors. The ASU enhances disclosure requirements for certain loan refinancings and restructurings by creditors when a borrower is experiencing financial difficulty, updates certain requirements related to accounting for credit losses under ASC 326 and requires disclosure of current-period gross write offs of financing receivables by year of origination. The ASU is effective for the Company for interim and annual periods in fiscal years beginning after December 15, 2022. The Company is currently completing its evaluation of the impact of adoption of this ASU, however, the impact of adoption on the Company's consolidated financial position, results of operations, and cash flows is not expected to be material. Adoption will lead to additional and revised disclosures in the Company's financial statements.

The Company monitors its investment securities available for sale for credit loss impairment on an individual security basis. No securities were determined to be credit loss impaired during the three and nine months ended September 30, 2022 and 2021. At September 30, 2022, the Company did not have an intent to sell securities that were in unrealized loss positions and it was not more likely than not that the Company would be required to sell these securities before recovery of the amortized cost basis, which may be at maturity. In making this determination, the Company considered its current and projected liquidity position, its investment policy as to permissible holdings and concentration limits, regulatory requirements and other relevant factors.

At September 30, 2022, 579 securities available for sale were in unrealized loss positions. The amount of impairment related to 96 of these securities was considered insignificant both individually and in the aggregate, totaling approximately $0.9 million and no further analysis with respect to these securities was considered necessary.

The basis for concluding that AFS securities were not credit loss impaired and no ACL was considered necessary at September 30, 2022 is further discussed below.

Unrealized losses were generally attributable to rising interest rates and widening spreads related to the Federal Reserve's quantitative tightening and benchmark interest rate increases. Continuing uncertainty with respect to the trajectory of the economy and geopolitical events have also led to market uncertainty, producing some yield curve dislocations.

U.S. Government Agency and Government Sponsored Enterprise Securities

At September 30, 2022, five U.S. treasury, 149 U.S. Government agency and sponsored enterprise residential MBS, 27 U.S. Government agency and sponsored enterprise commercial MBS, and 15 SBA securities were in unrealized loss positions. The timely payment of principal and interest on these securities is explicitly or implicitly guaranteed by the U.S. Government. As such, there is an assumption of zero credit loss and the Company expects to recover the amortized cost basis of these securities.

Private Label Securities:

None of the impaired private label securities had missed principal or interest payments or had been downgraded by a NRSRO at September 30, 2022. The Company performed an analysis comparing the present value of cash flows expected to be collected to the amortized cost basis of impaired securities. This analysis was based on a scenario that we believe to be generally more conservative than our reasonable and supportable economic forecast at September 30, 2022, and incorporated assumptions about voluntary prepayment rates, collateral defaults, delinquencies, severity and other relevant factors as described further below. Our analysis also considered the structural characteristics of each security and the level of credit enhancement provided by that structure.

Private label residential MBS and CMOs

At September 30, 2022, 115 private label residential MBS and CMOs were in unrealized loss positions. Our analysis of cash flows expected to be collected on these securities incorporated assumptions about collateral default rates, voluntary prepayment rates, loss severity, delinquencies and recovery lag. In developing those assumptions, we took into account collateral quality measures such as FICO, LTV, documentation, loan type, property type, agency availability criteria and performing status. We also regularly monitor sector data including home price appreciation, forbearance, delinquency and prepay trends as well as other economic data that could be indicative of stress in the sector. Our September 30, 2022 analysis projected weighted average collateral losses for impaired securities in this category of 3% compared to weighted average credit support of 18%. As of September 30, 2022, 94% of impaired securities in this category, based on carrying value, were externally rated AAA, 1% were rated AA and 5% were rated A.

Private label commercial MBS

At September 30, 2022, 109 private label commercial MBS were in unrealized loss positions. Our analysis of cash flows expected to be collected on these securities incorporated assumptions about collateral default rates, voluntary prepayment rates, loss severity, delinquencies and recovery lag. In developing those assumptions, we took into account collateral quality and type, loan size, loan purpose and other qualitative factors. We also regularly monitor collateral watch lists, bankruptcy data, defeasance data, special servicing trends, delinquency and other economic data that could be indicative of stress in the sector. Our September 30, 2022 analysis projected weighted average collateral losses for impaired securities in this category of 7% compared to weighted average credit support of 43%. As of September 30, 2022, 84% of impaired securities in this category, based on carrying value, were externally rated AAA, 12% were rated AA and 4% were rated A.

Single family real estate-backed securities

At September 30, 2022, 16 single family rental real estate-backed securities were in unrealized loss positions. Our analysis of cash flows expected to be collected on these securities incorporated assumptions about collateral default rates, loss severity, delinquencies and recovery lag. We regularly monitor sector data including home price appreciation, forbearance, delinquency and prepay trends as well as other economic data that could be indicative of stress in the sector. Our September 30, 2022 analysis projected weighted average collateral losses for this category of 8% compared to weighted average credit support of 50%. As of September 30, 2022, 63% of impaired securities in this category, based on carrying value, were externally rated AAA, 14% were rated AA and one security was not externally rated.

Collateralized loan obligations

At September 30, 2022, 26 collateralized loan obligations were in unrealized loss positions. Our analysis of cash flows expected to be collected on these securities incorporated assumptions about collateral default rates, loss severity, and delinquencies, calibrated to take into account idiosyncratic risks associated with the underlying collateral. In developing those assumptions, we took into account each sector’s performance pre-, during and post the 2008 financial crisis. We regularly engage with bond managers to monitor trends in underlying collateral including potential downgrades and subsequent cash flow diversions, liquidity, ratings migration, and any other relevant developments. Our September 30, 2022 analysis projected weighted average collateral losses for impaired securities in this category of 9% compared to weighted average credit support of 42%. As of September 30, 2022, 77% of the impaired securities in this category, based on carrying value, were externally rated AAA, 19% were rated AA and 4% were rated A.

Non-mortgage asset-backed securities

At September 30, 2022, seven non-mortgage asset-backed securities were in unrealized loss positions. These securities are backed by student loan collateral. Our analysis of cash flows expected to be collected on these securities incorporated assumptions about collateral default rates, loss severity, delinquencies, voluntary prepayment rates and recovery lag. In developing assumptions, we took into account collateral type, delineated by whether collateral consisted of loans to borrowers in school, refinancing, or a mixture. Our September 30, 2022 analysis projected weighted average collateral losses for impaired securities in this category of 4% compared to weighted average credit support of 23%. As of September 30, 2022, 51% of the impaired securities in this category, based on carrying value, were externally rated AAA, and 49% were rated AA.

The ACL increased by $4.2 million at September 30, 2022 compared to December 31, 2021, remaining largely consistent as a percentage of total loans. The provision for credit losses for the nine months ended September 30, 2022 was largely offset by net charge-offs. The more significant factors impacting the provision for credit losses for the nine months ended September 30, 2022, included increases in specific reserves and qualitative loss factors, loan growth, the decline in criticized and classified assets, and changes in certain assumptions including prepayment speeds.

Credit quality information

Credit quality of loans held for investment is continuously monitored by dedicated residential credit risk management and commercial portfolio management functions. The Company also has a workout and recovery department that monitors the credit quality of criticized and classified loans and an independent internal credit review function.

Credit quality indicators for residential loans

Management considers delinquency status to be the most meaningful indicator of the credit quality of residential and other consumer loans, other than government insured residential loans. Delinquency statistics are updated at least monthly. LTV and FICO scores are also important indicators of credit quality for 1-4 single family residential loans other than government insured loans. FICO scores are generally updated at least annually, and were most recently updated in the third quarter of 2022. LTVs are typically at origination since we do not routinely update residential appraisals. Substantially all of the government insured residential loans are government insured buyout loans, which the Company buys out of GNMA securitizations upon default. For these loans, traditional measures of credit quality are not particularly relevant considering the guaranteed nature of the loans and the underlying business model. Factors that impact risk inherent in the residential portfolio segment include national and regional economic conditions such as levels of unemployment and wages, as well as residential property values.

Credit quality indicators for commercial loans

Factors that impact risk inherent in commercial portfolio segments include but are not limited to levels of economic activity, health of the national and regional economy, industry trends, patterns of and trends in customer behavior that influence demand for our borrowers' products and services, and commercial real estate values. Internal risk ratings are considered the most meaningful indicator of credit quality for commercial loans. Internal risk ratings are generally indicative of the likelihood that a borrower will default, are a key factor influencing the level and nature of ongoing monitoring of loans and may impact the estimation of the ACL. Internal risk ratings are updated on a continuous basis. Generally, relationships with balances in excess of defined thresholds, ranging from $1 million to $3 million, are re-evaluated at least annually and more frequently if circumstances indicate that a change in risk rating may be warranted. Loans exhibiting potential credit weaknesses that deserve management’s close attention and that could result in deterioration of repayment prospects at some future date if not checked or corrected are categorized as special mention. Loans with well-defined credit weaknesses, including payment defaults, declining collateral values, frequent overdrafts, operating losses, increasing balance sheet leverage, inadequate cash flow from current

operations, project cost overruns, unreasonable construction delays, past due real estate taxes or exhausted interest reserves, are assigned an internal risk rating of substandard. A loan with a weakness so severe that collection in full is highly questionable or improbable, but because of certain reasonably specific pending factors has not been charged off, will be assigned an internal risk rating of doubtful.

Note 5    Income Taxes

The Company’s effective income tax rate was 25.0% and 24.7% for the three and nine months ended September 30, 2022, respectively, and 24.0% and 24.9% for the three and nine months ended September 30, 2021, respectively. The effective income tax rates differed from the statutory federal income tax rate of 21% due primarily to the impact of state income taxes, partially offset by the benefit of income not subject to federal tax.

Note 6    Derivatives and Hedging Activities

The Company has entered into interest rate swaps, caps and collars designated as cash flow hedges with the objective of limiting the variability of interest payment cash flows. The Company has also entered into interest rate swaps designated as fair value hedges designed to hedge changes in the fair value of outstanding fixed rate instruments caused by fluctuations in the benchmark interest rate.

The Company enters into interest rate derivative contracts with certain of its commercial borrowers to enable those borrowers to manage their exposure to interest rate fluctuations. To mitigate interest rate risk associated with these derivative contracts, the Company enters into offsetting derivative contract positions with primary dealers. These interest rate derivative contracts are not designated as hedging instruments; therefore, changes in the fair value of these derivatives are recognized immediately in earnings. For the three and nine months ended September 30, 2022 and 2021, the impact on earnings related to changes in fair value of these derivatives was not material.

The Company may be exposed to credit risk in the event of non-performance by the counterparties to its interest rate derivative agreements. The Company assesses the credit risk of its financial institution counterparties by monitoring publicly available credit rating and financial information. The Company manages dealer credit risk by entering into interest rate derivatives only with primary and highly rated counterparties, the use of ISDA master agreements, central clearing mechanisms and counterparty limits. The agreements contain bilateral collateral arrangements with the amount of collateral to be posted generally governed by the settlement value of outstanding swaps. The Company manages the risk of default by its commercial borrower counterparties through its normal loan underwriting and credit monitoring policies and procedures. The Company does not currently anticipate any significant losses from failure of interest rate derivative counterparties to honor their obligations.

The CME legally characterizes variation margin payments for centrally cleared derivatives as settlements of the derivatives' exposures rather than collateral. As a result, the variation margin payment and the related derivative instruments are considered a single unit of account for accounting and financial reporting purposes. The Company's clearing agent for interest rate derivative contracts centrally cleared through the CME settles the variation margin daily with the CME; therefore, those interest rate derivative contracts the Company clears through the CME are reported at a fair value of zero at both September 30, 2022 and December 31, 2021.

The following tables set forth certain information concerning the Company’s interest rate contract derivative financial instruments and related hedged items at the dates indicated (dollars in thousands):

Note 8    Fair Value Measurements

Assets and liabilities measured at fair value on a recurring basis

The following is a description of the methodologies used to estimate the fair values of assets and liabilities measured at fair value on a recurring basis and the level within the fair value hierarchy in which those measurements are typically classified.

Investment securities available for sale and marketable equity securities—Fair value measurements are based on quoted prices in active markets when available; these measurements are classified within level 1 of the fair value hierarchy. These securities typically include U.S. Treasury securities and certain preferred stocks. If quoted prices in active markets are not available, fair values are estimated using quoted prices of securities with similar characteristics, quoted prices of identical securities in less active markets, discounted cash flow techniques, or matrix pricing models. These securities are generally classified within level 2 of the fair value hierarchy and include U.S. Government agency securities, U.S. Government agency and sponsored enterprise MBS, preferred stock investments for which level 1 valuations are not available, non-mortgage asset-backed securities, single family real estate-backed securities, private label residential MBS and CMOs, private label commercial MBS, collateralized loan obligations and state and municipal obligations. Pricing of these securities is generally primarily spread driven. Observable inputs that may impact the valuation of these securities include benchmark yield curves, credit spreads, reported trades, dealer quotes, bids, issuer spreads, current rating, historical constant prepayment rates, historical voluntary prepayment rates, structural and waterfall features of individual securities, published collateral data, and for certain securities, historical constant default rates and default severities.

The Company uses third-party pricing services in determining fair value measurements for investment securities. To obtain an understanding of the methodologies and assumptions used, management reviews written documentation provided by the pricing services, conducts interviews with valuation desk personnel and reviews model results and detailed assumptions used to value selected securities as considered necessary. Management has established a robust price challenge process that includes a review by the treasury front office of all prices provided on a monthly basis. Any price evidencing unexpected month over month fluctuations or deviations from expectations is challenged. If considered necessary to resolve any discrepancies, a price will be obtained from an additional independent valuation source. The Company does not typically adjust the prices provided, other than through this established challenge process. The results of price challenges are subject to review by executive management. Any price discrepancies are resolved based on careful consideration of the assumptions and inputs employed by each of the pricing sources.

Derivative financial instruments—Fair values of interest rate swaps, caps and collars are determined using widely accepted discounted cash flow modeling techniques. These discounted cash flow models use projections of future cash payments and receipts that are discounted at mid-market rates. Observable inputs that may impact the valuation of these instruments include benchmark swap rates and benchmark forward yield curves. These fair value measurements are generally classified within level 2 of the fair value hierarchy.

Assets and liabilities measured at fair value on a non-recurring basis

Following is a description of the methodologies used to estimate the fair values of assets and liabilities that may be measured at fair value on a non-recurring basis, and the level within the fair value hierarchy in which those measurements are typically classified. 

Collateral dependent loans and OREO—The carrying amount of collateral dependent loans is typically based on the fair value of the underlying collateral, which may be real estate, enterprise value or other business assets, less estimated costs to sell when repayment is expected to come from the sale of the collateral. The carrying value of OREO is initially measured based on the fair value of the real estate acquired in foreclosure and subsequently adjusted to the lower of cost or estimated fair value, less estimated cost to sell. Fair values of real estate collateral and OREO are typically based on third-party real estate appraisals which utilize market and income approaches to valuation incorporating both observable and unobservable inputs.

Fair value measurements related to collateral dependent loans and OREO are generally classified within level 3 of the fair value hierarchy.

Operating lease equipment—Fair values of impaired operating lease equipment are typically based upon discounted cash flow analyses, considering expected lease rates and estimated end of life residual values, typically obtained from independent appraisals. These fair value measurements are classified within level 3 of the fair value hierarchy.

The following table presents the net carrying value of assets classified within level 3 of the fair value hierarchy at the dates indicated, for which non-recurring changes in fair value were recorded during the period then ended (in thousands):

Note 9    Commitments and Contingencies 

The Company issues off-balance sheet financial instruments to meet the financing needs of its customers. These financial instruments include commitments to fund loans, unfunded commitments under existing lines of credit, and commercial and standby letters of credit. These commitments expose the Company to varying degrees of credit and market risk which are essentially the same as those involved in extending loans to customers, and are subject to the same credit policies used in underwriting loans. Collateral may be obtained based on the Company’s credit evaluation of the counterparty. The Company’s maximum exposure to credit loss is represented by the contractual amount of these commitments.

Commitments to fund loans

These are agreements to lend funds to customers as long as there is no violation of any condition established in the contract. Commitments to fund loans generally have fixed expiration dates or other termination clauses and may require payment of a fee. Many of these commitments are expected to expire without being funded and, therefore, the total commitment amounts do not necessarily represent future liquidity requirements. 

Unfunded commitments under lines of credit

Unfunded commitments under lines of credit include commercial, commercial real estate and consumer lines of credit to existing customers, for many of which additional extensions of credit are subject to borrowing base requirements. Some of these commitments may mature without being fully funded, so may not necessarily represent future liquidity requirements. 

Commercial and standby letters of credit

Letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. These letters of credit are primarily issued to support trade transactions or guarantee arrangements. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers. 

Total lending related commitments outstanding at September 30, 2022 were as follows (in thousands):

Commitments to fund loans	$	618,765
Unfunded commitments under lines of credit	5,386,312
Commercial and standby letters of credit	113,730
	$	6,118,807

Legal Proceedings

The Company is involved as plaintiff or defendant in various legal actions arising in the normal course of business. In the opinion of management, based upon advice of legal counsel, the likelihood is remote that the impact of these proceedings, either individually or in the aggregate, would be material to the Company’s consolidated financial position, results of operations or cash flows.

Item 2.    Management's Discussion and Analysis of Financial Condition and Results of Operations 

The following discussion and analysis is intended to focus on significant matters impacting and changes in the financial condition and results of operations of the Company during the nine months ended September 30, 2022 and should be read in conjunction with the consolidated financial statements and notes hereto included in this Quarterly Report on Form 10-Q and BKU's 2021 Annual Report on Form 10-K for the year ended December 31, 2021 (the "2021 Annual Report on Form 10-K").

Forward-Looking Statements

This Quarterly Report on Form 10-Q contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 that reflect the Company’s current views with respect to, among other things, future events and financial performance. Words such as “anticipates,” “expects,” “intends,” “plans,” “believes,” “seeks,” “estimates,” "future" and similar expressions identify forward-looking statements. These forward-looking statements are based on the historical performance of the Company or on the Company’s current plans, estimates and expectations. The inclusion of this forward-looking information should not be regarded as a representation by the Company that the future plans, estimates or expectations so contemplated will be achieved. Such forward-looking statements are subject to various risks and uncertainties and assumptions relating to the Company’s operations, financial results, financial condition, business prospects, growth strategy and liquidity, including as impacted by external circumstances outside the Company's direct control. If one or more of these or other risks or uncertainties materialize, or if the Company’s underlying assumptions prove to be incorrect, the Company’s actual results may vary materially from those indicated in these statements. A number of important factors could cause actual results to differ materially from those indicated by the forward-looking statements, including, but not limited to, the risk factors described in Part I, Item 1A of the 2021 Annual Report on Form 10-K and any subsequent Quarterly Report on Form 10-Q or Current Report on Form 8-K. The Company does not undertake any obligation to publicly update or review any forward looking statement, whether as a result of new information, future developments or otherwise.

Overview

Quarterly Highlights

In evaluating our financial performance, we consider the level of and trends in net interest income, the net interest margin, the cost of deposits, levels and composition of non-interest income and non-interest expense, performance ratios such as the return on average equity and return on average assets and asset quality ratios, including the ratio of non-performing loans to total loans, non-performing assets to total assets, trends in criticized and classified assets and portfolio delinquency and charge-off trends. We consider growth in and the composition of earning assets and deposits, trends in funding mix and cost of funds. We analyze these ratios and trends against our own historical performance, our budgeted performance and the financial condition and performance of comparable financial institutions.

Quarterly highlights include:

•Net income for the three months ended September 30, 2022 was $87.9 million, or $1.12 per diluted share, compared to $65.8 million or $0.82 per diluted share for the immediately preceding three months ended June 30, 2022 and $86.9 million, or $0.94 per diluted share, for the three months ended September 30, 2021. Net income for the nine months ended September 30, 2022 was $220.8 million, or $2.71 per diluted share, compared to $289.7 million, or $3.12 per diluted share, for the nine months ended September 30, 2021. Earnings for the nine months ended September 30, 2021 were favorably impacted by a $67.4 million recovery of the provision for credit losses.

•PPNR was $120.8 million for the three months ended September 30, 2022 compared to $111.5 million for the immediately preceding three months ended June 30, 2022 and $102.6 million for the three months ended September 30, 2021.

•The net interest margin, calculated on a tax-equivalent basis, expanded to 2.76% for the three months ended September 30, 2022 from 2.63% for the immediately preceding quarter and 2.33% for the three months ended September 30, 2021. Net interest income increased by $10.4 million compared to the immediately preceding three months ended June 30, 2022 and by $40.7 million compared to the three months ended September 30, 2021.

•In response to the rising interest rate environment, the average cost of total deposits increased to 0.78% for the three months ended September 30, 2022, from 0.30% for the immediately preceding three months ended June 30, 2022 and 0.20% for the three months ended September 30, 2021. The yield on average interest earning assets increased to 3.80% for the three months ended September 30, 2022 from 3.11% for the immediately preceding quarter and 2.79% for the three months ended September 30, 2021.

33

•For the three months ended September 30, 2022, the Company recorded a provision for credit losses of $3.7 million compared to a provision of $24.0 million for the immediately preceding three months ended June 30, 2022 and a recovery of the provision for credit losses of $(11.8) million for the three months ended September 30, 2021. The ratio of the ACL to total loans was consistent with the prior quarter-end at 0.54%.

•Loans, excluding the runoff of PPP loans, grew by $186 million for the three months ended September 30, 2022. The C&I and commercial real estate portfolio segments grew by a total of $444 million. As expected given the market-wide decline in mortgage origination activity, mortgage warehouse loans declined by $194 million.

•Total deposits declined by $1.1 billion during the three months ended September 30, 2022. Non-interest bearing demand deposits declined by $851 million to 32% of total deposits, from 34% of total deposits at June 30, 2022. Year to date, non-interest bearing demand deposits declined by $182 million. Time deposits grew by $976 million during the three months ended September 30, 2022, reflecting a strategy to extend the term of deposits.

•The positive trend in levels of criticized and classified loans continued during the three months ended September 30, 2022, declining by $175 million; the annualized net charge-off ratio was 0.16% compared to 0.29% for the year ended December 31, 2021. The ratio of non-performing loans to total loans was 0.64% at September 30, 2022. The guaranteed portion of SBA loans on non-accrual status represented 0.17% of total loans and 27% of non-performing loans at September 30, 2022.

•Book value per common share and tangible book value per common share were $31.97 and $30.97, respectively, at September 30, 2022.

•In September 2022, the Company's Board of Directors authorized the repurchase of up to an additional $150 million in shares of its outstanding common stock. During the three months ended September 30, 2022, the Company repurchased approximately 0.3 million shares of its common stock for an aggregate purchase price of $10.8 million, at a weighted average price of $34.36 per share.

Hurricane Ian

In September 2022, Hurricane Ian made landfall on the southwest Florida coast. The Company did not sustain significant damage or disruption to facilities or operations. The Company had approximately $2.3 billion UPB, based on September 30, 2022 balances, of loans within a 20 county assessment area most impacted by the storm. As of October 25, 2022, we have contacted borrowers representing approximately 75% of this exposure. No borrowers reported severe impact from the storm; borrowers representing approximately $159 million in UPB reported mild or moderate impact on their properties or businesses. Based on information collected to date, we do not expect the impact of the storm to be material to our financial condition or results of operations.

Results of Operations

Net Interest Income

Net interest income is the difference between interest earned on interest earning assets and interest incurred on interest bearing liabilities and is the primary driver of core earnings. Net interest income is impacted by the mix of interest earning assets and interest bearing liabilities, the ratio of interest earning assets to total assets and of interest bearing liabilities to total funding sources, movements in market interest rates, the shape of the yield curve, levels of non-performing assets and pricing pressure from competitors.

The mix of interest earning assets is influenced by loan demand, market and competitive conditions in our primary lending markets, by management's continual assessment of the rate of return and relative risk associated with various classes of earning assets and liquidity considerations. The mix of interest bearing liabilities is influenced by the Company's liquidity profile, management's assessment of the desire for lower cost funding sources weighed against relationships with customers and growth expectations, our ability to attract and retain core deposit relationships, competition for deposits in the Company's markets and the availability and pricing of other sources of funds.

The following table presents, for the periods indicated, information about (i) average balances, the total dollar amount of taxable equivalent interest income from earning assets and the resultant average yields; (ii) average balances, the total dollar amount of interest expense on interest bearing liabilities and the resultant average rates; (iii) net interest income; (iv) the interest rate spread; and (v) the net interest margin. Non-accrual loans are included in the average balances presented in this table; however, interest income foregone on non-accrual loans is not included. Interest income, yields, spread and margin have been calculated on a tax-equivalent basis for loans and investment securities that are exempt from federal income taxes, at a federal tax rate of 21% (dollars in thousands):

Three months ended September 30, 2022 compared to the immediately preceding three months ended June 30, 2022

Net interest income, calculated on a tax-equivalent basis, was $239.9 million for the three months ended September 30, 2022, compared to $229.3 million for the three months ended June 30, 2022, an increase of $10.5 million. The increase in net interest income was comprised of an increase in tax-equivalent interest income of $59.2 million partially offset by an increase of $48.6 million in interest expense. The increase in interest income reflected higher yields on loans and investment securities. The increase in interest expense reflected a higher cost of interest bearing deposits in response to the rising interest rate environment.

The net interest margin, calculated on a tax-equivalent basis, was 2.76% for the three months ended September 30, 2022, compared to 2.63% for the three months ended June 30, 2022. Offsetting factors impacting the net interest margin for the three months ended September 30, 2022 compared to the immediately preceding three months ended June 30, 2022 included:

•The tax-equivalent yield on investment securities increased to 3.12% from 2.12%. This increase resulted primarily from the reset of coupon rates on variable rate securities as well as purchases of securities at higher yields.

•The tax-equivalent yield on loans increased to 4.11% from 3.59%. Factors contributing to this increase were the resetting of variable rate loans at higher coupon rates and originations of new loans at higher rates.

•The average rate paid on interest bearing deposits increased to 1.14% from 0.45%, primarily in response to the rising interest rate environment. Growth in time deposits as a percentage of interest bearing deposits also contributed to this increase, as we implemented a strategy to extend the term of interest bearing deposits.

36

•The average rate paid on FHLB advances increased to 2.25% for the three months ended September 30, 2022, from 1.07% for the three months ended June 30, 2022, primarily in response to the rising interest rate environment.

Three and nine months ended September 30, 2022 compared to the three and nine months ended September 30, 2021

Net interest income, calculated on a tax-equivalent basis, was $239.9 million for the three months ended September 30, 2022, compared to $199.1 million for the three months ended September 30, 2021, an increase of $40.7 million. Net interest income, calculated on a tax-equivalent basis, was $681.5 million for the nine months ended September 30, 2022, compared to $601.9 million for the nine months ended September 30, 2021, an increase of $79.5 million. The increases in net interest income were comprised of increases in tax-equivalent interest income of $91.7 million and $106.7 million partially offset by increases in interest expense of $51.0 million and $27.2 million for the three and nine months ended September 30, 2022, respectively, compared to the three and nine months ended September 30, 2021, respectively.

Increases in interest income for the three and nine months ended September 30, 2022, compared to the three and nine months ended September 30, 2021, reflected increases in both the average balance of and yields on loans and rising yields on investment securities. Increases in interest expense for the three and nine months ended September 30, 2022, compared to the three and nine months ended September 30, 2021, reflected the increased cost of interest bearing deposits related to the rising rate environment, partially offset by declines in the related average balances. For the comparative three-month periods, interest expense on FHLB advances increased mainly due to an increase in the average balance, while for the comparative nine-month periods, interest expense on FHLB advances declined due to a decrease in the weighted average rate, partially offset by an increase in the average balance.

The net interest margin, calculated on a tax-equivalent basis, was 2.76% for the three months ended September 30, 2022, compared to 2.33% for the three months ended September 30, 2021. The net interest margin, calculated on a tax-equivalent basis, was 2.63% for the nine months ended September 30, 2022, compared to 2.36% for the nine months ended September 30, 2021. Offsetting factors impacting the net interest margin for the three and nine months ended September 30, 2022, compared to the three and nine months ended September 30, 2021 included:

•The tax-equivalent yield on loans expanded to 4.11% and 3.69% for the three and nine months ended September 30, 2022, respectively, from 3.45% and 3.54% for the three and nine months ended September 30, 2021, respectively. Factors contributing to the increases in the tax-equivalent yield on loans for the three and nine months ended September 30, 2022, compared to the comparable periods in 2021 were largely consistent with those discussed above.

•The tax-equivalent yield on investment securities increased to 3.12% and 2.32% for the three and nine months ended September 30, 2022, respectively, from 1.49% and 1.59% for the three and nine months ended September 30, 2021, respectively. The reset of coupon rates on variable rate securities, purchases of higher-yielding securities and slowing prepayment speeds on securities purchased at a premium contributed to these increases in yields.

•The average rate paid on interest bearing deposits increased to 1.14% and 0.60% for the three and nine months ended September 30, 2022, respectively, from 0.29% and 0.36% for the three and nine months ended September 30, 2021, respectively, reflecting the increasing trend in the Fed's benchmark rate.

•The average rate paid on FHLB advances decreased to 2.25% and 1.57% for the three and nine months ended September 30, 2022, respectively, from 2.35% and 2.34% for the three and nine months ended September 30, 2021, respectively. The decreases resulted from the maturity of higher rate advances and the termination of certain cash flow hedges in the fourth quarter of 2021, coupled with the addition of FHLB advances at lower prevailing rates.

Provision for Credit Losses

The provision for credit losses is a charge or credit to earnings required to maintain the ACL at a level consistent with management’s estimate of expected credit losses on financial assets carried at amortized cost at the balance sheet date. The amount of the provision is impacted by changes in current economic conditions as well as in management's reasonable and supportable economic forecast, loan originations and runoff, changes in portfolio mix, risk rating migration and portfolio seasoning, changes in specific reserves, changes in expected prepayment speeds and other assumptions. The provision for credit losses also includes amounts related to off-balance sheet credit exposures and may include amounts related to accrued interest receivable and AFS debt securities.

37

The following table presents the components of the provision for (recovery of) credit losses for the periods indicated (in thousands):

	Three Months Ended September 30,				Nine Months Ended September 30,
	2022		2021		2022		2021
Amount related to funded portion of loans	$	2,753	$	(11,554)	$	33,406	$	(65,523)
Amount related to off-balance sheet credit exposures	967		280		2,267		(640)
Amount related to accrued interest receivable	—		(568)		(127)		(838)
Amount related to AFS debt securities	—		—		—		(364)
Total provision for (recovery of) credit losses	$	3,720	$	(11,842)	$	35,546	$	(67,365)

The provision for credit losses for the three months ended September 30, 2022, included an increase related to the updated economic forecast, increases in specific reserves, loan growth and a $5 million provision related to the potential impact of Hurricane Ian, partially offset by decreases in certain qualitative factors and the impact of improving borrower financial results.

The provision for credit losses for the nine months ended September 30, 2022 was impacted by increases in specific reserves, the $5 million provision related to Hurricane Ian, loan growth, the decline in criticized and classified assets, and changes in certain assumptions, particularly prepayment speeds.

The provision for credit losses may continue to be volatile and the level of the ACL may change materially from current levels. Future levels of the ACL could be significantly impacted, in either direction, by changes in factors such as economic conditions or the economic outlook, in composition of the loan portfolio, in the financial condition of our borrowers and collateral values.

The determination of the amount of the ACL is complex and involves a high degree of judgment and subjectivity. See “Analysis of the Allowance for Credit Losses” below for more information about how we determine the appropriate level of the ACL and about factors that impacted the ACL for the three and nine months ended September 30, 2022.

Non-Interest Income

The following table presents a comparison of the categories of non-interest income for the periods indicated (in thousands):

	Three Months Ended September 30,				Nine Months Ended September 30,
	2022		2021		2022		2021
Deposit service charges and fees	$	6,064	$	5,553	$	17,920	$	15,870
Gain (loss) on investment securities:
Net realized gain on sale of securities AFS	349		815		3,927		7,623
Net unrealized loss on marketable equity securities	(214)		(1,479)		(20,052)		(1,767)
Gain (loss) on investment securities, net	135		(664)		(16,125)		5,856
Lease financing	13,180		13,212		39,958		39,222
Other non-interest income	3,693		7,377		9,070		27,583
	$	23,072	$	25,478	$	50,823	$	88,531

The unrealized losses on marketable equity securities reflected in the table above were attributable to the decline in the fair value of certain preferred stock investments resulting from rising market interest rates and widening spreads.

The most significant factors leading to the decrease in other non-interest income for the three and nine months ended September 30, 2022, compared to the three and nine months ended September 30, 2021, were declines in BOLI revenue related to the rising interest rate environment and lower gains on sale of loans. Lower gains on sale of loans related to a less favorable environment for the re-pooling of GNMA early buyout loans, again related to the rising interest rate environment.

38

Non-Interest Expense

The following table presents the components of non-interest expense for the periods indicated (in thousands):

	Three Months Ended September 30,				Nine Months Ended September 30,
	2022		2021		2022		2021
Employee compensation and benefits	$	66,097	$	57,224	$	195,646	$	172,971
Occupancy and equipment	11,719		11,760		34,630		35,127
Deposit insurance expense	4,398		3,552		11,794		15,224
Professional fees	3,184		2,312		8,702		6,363
Technology	19,813		16,687		54,715		49,279
Depreciation of operating lease equipment	12,646		12,944		37,841		37,995
Other non-interest expense	20,248		13,563		48,503		42,756
Total non-interest expense	$	138,105	$	118,042	$	391,831	$	359,715

Non-interest expense increased by $20.1 million and $32.1 million for the three and nine months ended September 30, 2022, compared to the three and nine months ended September 30, 2021. As expected, an increasing trend was reflected in the compensation and technology categories, as we continue to invest in people and technology to support future growth. Compensation expense also reflects increasing costs related to the competitive labor market and medical benefits. The increase in other non-interest expense includes a $2.3 million write-off of a technology investment during the three months ended September 30, 2022.

See Note 5 to the consolidated financial statements for information about income taxes.

Analysis of Financial Condition

Average interest-earning assets increased by $555 million to $34.6 billion for the nine months ended September 30, 2022 from $34.0 billion for the nine months ended September 30, 2021, reflecting increases in average balances of both loans and investment securities. Average interest bearing liabilities increased by $160 million. Average FHLB advances increased by $933 million. Average interest-bearing deposits declined by $899 million, while average non-interest bearing deposits increased by $877 million for the nine months ended September 30, 2022 compared to the nine months ended September 30, 2021; average total deposits was stable for the comparative nine-month periods. During the three months ended September 30, 2022, in response to the rising interest rate environment and quantitative tightening by the Fed, average interest bearing liabilities increased by $527 million, while average non-interest bearing demand deposits declined by $669 million.

Our investment strategy has focused on insuring adequate liquidity, maintaining a suitable balance of high credit quality, diverse assets, managing interest rate risk, and generating acceptable returns given our established risk parameters. We have sought to maintain liquidity by investing a significant portion of the portfolio in high quality liquid securities including U.S. Treasury and U.S. Government Agency and sponsored enterprise securities. Investment grade municipal securities provide liquidity and attractive tax-equivalent yields. We have also invested in highly rated structured products, including private-label commercial and residential MBS, collateralized loan obligations, single family real estate-backed securities and non-mortgage asset-backed securities that, while somewhat less liquid, provide us with attractive yields. Relatively short effective portfolio duration helps mitigate interest rate risk. Based on the Company’s assumptions, the estimated weighted average life of the investment portfolio as of September 30, 2022 was 4.7 years and the effective duration of the portfolio was 2.0 years.

The investment securities available for sale portfolio was in a net unrealized loss position of $635.5 million at September 30, 2022, compared to a net unrealized gain position of $3.8 million at December 31, 2021. Net unrealized losses at September 30, 2022 included $1.9 million of gross unrealized gains and $637.5 million of gross unrealized losses. Investment securities available for sale in unrealized loss positions at September 30, 2022 had an aggregate fair value of $9.2 billion. The unrealized losses resulted primarily from rising interest rates and widening spreads related to the Federal Reserve's quantitative tightening and benchmark interest rate increases. Continuing uncertainty with respect to the trajectory of the economy and geopolitical events have also led to market uncertainty, producing some yield curve dislocations. None of the unrealized losses were attributable to credit loss impairments.

40

The ratings distribution of our AFS securities portfolio at September 30, 2022 is depicted in the chart below:

We evaluate the credit quality of individual securities in the portfolio quarterly to determine whether we expect to recover the amortized cost basis of the investments in unrealized loss positions. This evaluation considers, but is not necessarily limited to, the following factors, the relative significance of which varies depending on the circumstances pertinent to each individual security:

•Whether we intend to sell the security prior to recovery of its amortized cost basis;

•Whether it is more likely than not that we will be required to sell the security prior to recovery of its amortized cost basis;

•The extent to which fair value is less than amortized cost;

•Adverse conditions specifically related to the security, an industry or geographic area;

•Changes in the financial condition of the issuer or underlying loan obligors;

•The payment structure and remaining payment terms of the security, including levels of subordination or over-collateralization;

•Failure of the issuer to make scheduled payments;

•Changes in credit ratings;

•Relevant market data;

•Estimated prepayments, defaults, and the value and performance of underlying collateral at the individual security level.

We do not intend to sell securities in significant unrealized loss positions at September 30, 2022. Based on an assessment of our liquidity position and internal and regulatory guidelines for permissible investments and concentrations, it is not more likely than not that we will be required to sell securities in significant unrealized loss positions prior to recovery of amortized cost basis, which may be at maturity.

We regularly engage with bond managers to monitor trends in underlying collateral including potential downgrades and subsequent cash flow diversions, liquidity, ratings migration, and any other relevant developments.

For further discussion of our analysis of impaired investment securities AFS for credit loss impairment see Note 3 to the consolidated financial statements.

We use third-party pricing services to assist us in estimating the fair value of investment securities. We perform a variety of procedures to ensure that we have a thorough understanding of the methodologies and assumptions used by the pricing services including obtaining and reviewing written documentation of the methods and assumptions employed, conducting interviews with valuation desk personnel and reviewing model results and detailed assumptions used to value selected securities as considered necessary. Our classification of prices within the fair value hierarchy is based on an evaluation of the nature of the significant assumptions impacting the valuation of each type of security in the portfolio. We have established a robust price challenge process that includes a review by our treasury front office of all prices provided on a monthly basis. Any price evidencing unexpected month over month fluctuations or deviations from our expectations based on recent observed trading activity and other information available in the marketplace that would impact the value of the security is challenged. Responses to the price challenges, which generally include specific information about inputs and assumptions incorporated in the valuation and their sources, are reviewed in detail. If considered necessary to resolve any discrepancies, a price will be obtained from additional independent valuation sources. We do not typically adjust the prices provided, other than through this established challenge process. Our primary pricing services utilize observable inputs when available, and employ unobservable inputs and proprietary models only when observable inputs are not available. As a matter of course, the services validate prices by comparison to recent trading activity whenever such activity exists. Quotes obtained from the pricing services are typically non-binding.

The majority of our investment securities are classified within level 2 of the fair value hierarchy. U.S. Treasury securities and marketable equity securities are classified within level 1 of the hierarchy.

For additional discussion of the fair values of investment securities, see Note 8 to the consolidated financial statements.

For the nine months ended September 30, 2022, total loans grew by $502 million, while total loans, excluding PPP loans, grew by $740 million.

Growth in residential and other consumer loans for the nine months ended September 30, 2022 totaled $486 million. Commercial and industrial loans, including owner-occupied commercial real estate, grew by $971 million for the nine months ended September 30, 2022. Most of the remaining commercial portfolio segments showed declines during the nine months ended September 30, 2022. MWL declined by $469 million for this period, with utilization declining to 32% at September 30, 2022, from 56% at December 31, 2021, as rising rates have led to lower refinancing and mortgage origination activity. PPP loans declined by $238 million during the nine months ended September 30, 2022, resulting primarily from full or partial forgiveness from the SBA.

Other consumer loans	4,673		6,934
	$	8,853,884	$	8,368,380

The 1-4 single family residential loan portfolio, excluding government insured residential loans, is primarily comprised of loans purchased through established correspondent channels. 1-4 single family residential mortgage loans are primarily closed-end, first lien jumbo mortgages for the purchase or re-finance of owner occupied property. The loans have terms ranging from 10 to 30 years, with either fixed or adjustable interest rates. At September 30, 2022, $1.1 billion or 15% were secured by investor-owned properties.

The Company acquires non-performing FHA and VA insured mortgages from third party servicers who have exercised their right to purchase these loans out of GNMA securitizations (collectively, "government insured pool buyout loans" or "buyout loans"). Buyout loans that re-perform, either through modification or self-cure, may be eligible for re-securitization. The Company and the servicer share in the economics of the sale of these loans into new securitizations. During the nine months ended September 30, 2022 and 2021, the Company purchased $475 million and $1.3 billion, respectively, of government insured residential loans. The balance of buyout loans totaled $1.8 billion at September 30, 2022. The Company is not the servicer of these loans.

Asset Quality

Commercial Loans

We have a robust credit risk management framework, an experienced team to lead the workout and recovery process for the commercial and commercial real estate portfolios and a dedicated internal credit review function. Loan performance is monitored by our credit administration, portfolio management and workout and recovery departments. Generally, commercial relationships with balances in excess of defined thresholds are re-evaluated at least annually and more frequently if circumstances indicate that a change in risk rating may be warranted. The defined thresholds range from $1 million to $3 million. Homogenous groups of smaller balance commercial loans may be monitored collectively. The credit quality and risk rating of commercial loans as well as our underwriting and portfolio management practices are regularly reviewed by our internal independent credit review department.

We believe internal risk rating is the best indicator of the credit quality of commercial loans. The Company utilizes a 16-grade internal asset risk classification system as part of its efforts to monitor and maintain commercial asset quality. The special mention rating is considered a transitional rating for loans exhibiting potential credit weaknesses that could result in deterioration of repayment prospects at some future date if not checked or corrected and that deserve management’s close attention. These borrowers may exhibit declining cash flows or revenues or increasing leverage. Loans with well-defined credit weaknesses that may result in a loss if the deficiencies are not corrected are assigned a risk rating of substandard. These borrowers may exhibit payment defaults, inadequate cash flows from current operations, operating losses, increasing balance sheet leverage, project cost overruns, unreasonable construction delays, exhausted interest reserves, declining collateral values, frequent overdrafts or past due real estate taxes. Loans with weaknesses so severe that collection in full is highly questionable or improbable, but because of certain reasonably specific pending factors have not been charged off, are assigned an internal risk rating of doubtful.

The following table summarizes the Company's commercial credit exposure, based on internal risk rating, at the dates indicated (dollars in thousands):

Our internal risk ratings at September 30, 2022 continued to be influenced by the impact of the COVID-19 pandemic as sustained operating cash flows of some borrowers has yet to fully recover, although that impact continues to decline. Management took what it believed to be a proactive and objective approach to risk rating the commercial loan portfolio at the onset of the pandemic. Levels of criticized and classified loans, particularly in the special mention and substandard accruing categories, increased over the course of 2020 as a direct result of the impact of the COVID-19 pandemic. Throughout 2021 and the nine months ended September 30, 2022, levels of criticized and classified loans declined in response to the trajectory of the economic recovery and lessening impact of the pandemic.

Operating Lease Equipment, net

Operating leases with a carrying value of assets under lease totaling $18 million, were internally risk rated substandard at September 30, 2022. On a quarterly basis, management performs an impairment analysis on assets with indicators of potential impairment. Potential impairment indicators include evidence of changes in residual value, macro-economic conditions, an extended period of time off-lease, criticized or classified status, or management's intention to sell the asset at an amount potentially below its carrying value. There were no impairment charges recognized during the three and nine months ended September 30, 2022 and 2021.

Bridge had exposure to the energy industry of $259 million at September 30, 2022. The majority of the energy exposure was in the operating lease equipment portfolio where energy exposure totaled $226 million.

Residential Loans

Our residential mortgage portfolio, excluding GNMA buyout loans, consists primarily of loans purchased through established correspondent channels. Most of our purchases are of performing jumbo mortgage loans which have FICO scores above 700, primarily are owner-occupied and full documentation, and have a current LTV of 80% or less although loans with LTVs higher than 80% may be extended to selected credit-worthy borrowers. We perform due diligence on the purchased loans for credit, compliance, counterparty, payment history and property valuation.

We have a dedicated residential credit risk management function, and the residential portfolio is monitored by our internal credit review function. Residential mortgage loans are not individually risk rated. Delinquency status is the primary measure we use to monitor the credit quality of these loans. We also consider original LTV and most recently available FICO score to be

49

significant indicators of credit quality for the 1-4 single family residential portfolio, excluding government insured residential loans.

The following charts present information about the 1-4 single family residential portfolio, excluding government insured loans, by FICO distribution, LTV distribution and vintage at September 30, 2022:

FICO scores are generally updated at least annually, and were most recently updated in the third quarter of 2022. LTVs are typically based on valuation at origination since we do not routinely update residential appraisals.

At September 30, 2022, the majority of the 1-4 single family residential loan portfolio, excluding government insured residential loans, was owner-occupied, with 80% primary residence, 5% second homes and 15% investment properties.

1-4 single family residential loans excluding government insured residential loans past due more than 30 days totaled $55 million and $76 million at September 30, 2022 and December 31, 2021, respectively. The amount of these loans 90 days or more past due was $14 million and $17 million at September 30, 2022 and December 31, 2021, respectively.

Note 4 to the consolidated financial statements presents additional information about key credit quality indicators and delinquency status of the loan portfolio.

Non-Performing Assets

Non-performing assets generally consist of (i) non-accrual loans, including loans that have been modified in TDRs or CARES Act modifications and placed on non-accrual status, (ii) accruing loans that are more than 90 days contractually past due as to interest or principal, excluding PCD loans for which management has a reasonable basis for an expectation about future cash flows and government insured residential loans, and (iii) OREO and other non-performing assets.

Commercial loans are placed on non-accrual status when (i) management has determined that full repayment of all contractual principal and interest is in doubt, or (ii) the loan is past due 90 days or more as to principal or interest unless the loan is well secured and in the process of collection. Residential and consumer loans, other than government insured pool buyout loans, are generally placed on non-accrual status when they are 90 days past due. When a loan is placed on non-accrual status, uncollected interest accrued is reversed and charged to interest income. Commercial loans are returned to accrual status only after all past due principal and interest has been collected and full repayment of remaining contractual principal and interest is reasonably assured. Residential loans are generally returned to accrual status when less than 90 days past due. Past due status of loans is determined based on the contractual next payment due date. Loans less than 30 days past due are reported as current.

TDRs

A loan modification is considered a TDR if the Company, for economic or legal reasons related to the borrower’s financial difficulties, grants a concession to the borrower that the Company would not otherwise grant. These concessions may take the form of temporarily or permanently reduced interest rates, payment abatement periods, restructuring of payment terms or extensions of maturity at below market terms. Included in TDRs are residential loans to borrowers who have not reaffirmed their debt discharged in Chapter 7 bankruptcy.

Under inter-agency and authoritative guidance and consistent with the CARES Act, short-term deferrals or modifications related to COVID-19 were typically not categorized as TDRs. Additionally, section 4013 of the CARES Act, as amended by the Consolidated Appropriations Act, effectively suspended the guidance related to TDRs codified in ASC 310-40 until January 1, 2022, the date the CARES Act expired.

The following table summarizes loans that had been modified in TDRs at the dates indicated (dollars in thousands):

	September 30, 2022					December 31, 2021
	Number of TDRs	Amortized Cost		Related Specific Allowance		Number of TDRs	Amortized Cost		Related Specific Allowance

(1)    Includes 2,397 government insured residential loans modified in TDRs totaling $380.1 million at September 30, 2022, and 435 government insured residential loans modified in TDRs totaling $76.4 million at December 31, 2021.

See Note 4 to the consolidated financial statements for additional information about TDRs.

Loss Mitigation Strategies

Criticized or classified commercial loans in excess of certain thresholds are reviewed quarterly by the Criticized Asset Committee, which evaluates the appropriate strategy for collection to mitigate the amount of credit losses and considers the appropriate risk rating for these loans. Criticized asset reports for each relationship are presented by the assigned relationship manager and credit officer to the Criticized Asset Committee until such time as the relationships are returned to a satisfactory credit risk rating or otherwise resolved. The Criticized Asset Committee may require the transfer of a loan to our workout and recovery department, which is tasked to effectively manage the loan with the goal of minimizing losses and expenses associated with restructure, collection and/or liquidation of collateral. Commercial loans with a risk rating of substandard, loans on non-accrual status, loans modified as TDRs and assets classified as OREO or repossessed assets are usually transferred to workout and recovery. Oversight of the workout and recovery department is provided by the Criticized Asset Committee.

Our servicers evaluate each residential loan in default to determine the most effective loss mitigation strategy, which may be modification, short sale, or foreclosure, and pursue the alternative most suitable to the consumer and to mitigate losses to the bank.

In response to the COVID-19 pandemic and its potential economic impact to our customers, we implemented a short-term program that complied with interagency guidance and the CARES Act under which we provided temporary relief, and in some cases longer term modifications, on a case by case basis to borrowers directly impacted by COVID-19 who were not more than 30 days past due as of December 31, 2019. The CARES Act expired effective January 1, 2022. At September 30, 2022, the amount of loans remaining under CARES Act modification was not significant.

Analysis of the Allowance for Credit Losses

The ACL is management's estimate of the amount of expected credit losses over the life of the loan portfolio, or the amount of amortized cost basis not expected to be collected, at the balance sheet date. This estimate encompasses information about historical events, current conditions and reasonable and supportable economic forecasts. Determining the amount of the ACL is complex and requires extensive judgment by management about matters that are inherently uncertain. Given the current emerging level of economic uncertainty, the complexity of the ACL estimate and level of management judgment required, we believe it is possible that the ACL estimate could change, potentially materially, in future periods. Changes in the ACL may result from changes in current economic conditions, our economic forecast, loan portfolio composition and circumstances not currently known to us that may impact the financial condition and operations of our borrowers, among other factors.

50

Expected credit losses are estimated on a collective basis for groups of loans that share similar risk characteristics. For loans that do not share similar risk characteristics with other loans such as collateral dependent loans and TDRs, expected credit losses are estimated on an individual basis. Expected credit losses are estimated over the contractual terms of the loans, adjusted for expected prepayments, generally excluding expected extensions, renewals, and modifications.

For the substantial majority of portfolio segments and subsegments, including residential loans other than government insured loans, and most commercial and commercial real estate loans, expected losses are estimated using econometric models. The models employ a factor based methodology, leveraging data sets containing extensive historical loss and recovery information by industry, geography, product type, collateral type and obligor characteristics, to estimate PD and LGD. Measures of PD for commercial loans incorporate current conditions through market cycle or credit cycle adjustments. For residential loans, the models consider FICO and adjusted LTVs. PDs and LGDs are then conditioned on the reasonable and supportable economic forecast. Projected PDs and LGDs, determined based on pool level characteristics, are applied to estimated exposure at default, considering the contractual term and payment structure of loans, adjusted for prepayments, to generate estimates of expected loss. For criticized or classified loans, PDs are adjusted to benchmark PDs established for each risk rating. The ACL estimate incorporates a reasonable and supportable economic forecast through the use of externally developed macroeconomic scenarios applied in the models.

A single economic scenario or a probability weighted blend of economic scenarios may be used. The models ingest numerous national, regional and MSA level variables and data points. At September 30, 2022 and December 31, 2021, we used a single externally provided baseline scenario in calculating the quantitative portion of the ACL. At September 30, 2022, we incorporated a downside scenario to inform the amount of qualitative reserves.

Commercial Real Estate Model

Variables with the most significant impact on the commercial real estate model include unemployment at both national and regional levels, the CRE property forecast by property type and sub-market, 10-year treasury yield, Baa corporate yield and real GDP growth, at the national level. Increases in unemployment and yields within the commercial real estate model generally result in increases in the ACL. Increases in real GDP growth and improvements in the CRE property forecasts reduce the reserve.

Commercial Model

Variables with the most significant impact on the commercial model include a stock market volatility index, the S&P 500 index, unemployment at both national and regional levels, and a variety of interest rates and spreads. Increases in the unemployment rate, the stock market volatility index, and the Baa corporate yield increase the reserve, while increases in real GDP growth and the steepening of the yield curve reduce the reserve.

Residential Model

Variables with the most significant impact on the residential model include HPI and unemployment at regional levels, real GDP growth, and a 30-year mortgage rate. Increases in the unemployment rate and the 30-year mortgage rate increase the reserve, while increases in real GDP growth and HPI reduce the reserve.

The length of the reasonable and supportable forecast period is evaluated at each reporting period and adjusted if deemed necessary. Currently, the Company uses a 2-year reasonable and supportable forecast period in estimating the quantitative portion of the ACL. After the reasonable and supportable forecast period, the models effectively revert to long-term mean losses on a straight-line basis over 12 months.

For certain less material portfolios including loans and leases to state and local government entities originated by Pinnacle, small balance commercial loans and consumer loans, the WARM method is used to estimate expected credit losses. Loss rates are applied to the exposure at default, after factoring in amortization and expected prepayments. Expected credit losses for the funded portion of mortgage warehouse lines of credit are estimated based primarily on the Company's historical loss experience. All loss estimates are conditioned as applicable on changes in current conditions and the reasonable and supportable economic forecast.

The Company expects to collect the amortized cost basis of government insured residential loans and PPP loans due to the nature of the government guarantee, so the ACL is zero for these loans.

51

Qualitative factors

Qualitative adjustments are made to the ACL when, based on management’s judgment, there are factors impacting expected credit losses not taken into account by the quantitative calculations. Potential qualitative adjustments are categorized as follows:

•Economic factors;

•Credit policy and staffing;

•Concentrations;

•Model imprecision; and

•Other factors deemed appropriate by management that may materially impact the amount of expected credit losses.

See Note 1 to the consolidated financial statements of the Company's 2021 Annual Report on Form 10-K for more detailed information about our ACL methodology.

Significant offsetting factors contributing to the change in the ACL during the three months ended September 30, 2022 are depicted in the chart below (in millions):

Changes in the ACL during the three months ended September 30, 2022

Overall, the ACL as a percentage of loans remained consistent at 0.54% at September 30, 2022, compared to June 30, 2022. The qualitative portion of the ACL declined for the quarter ended September 30, 2022, as in management's judgment, the economic forecast underlying the quantitative estimate better captured the expected future trajectory of the economy; additionally, higher qualitative loss factors applied to certain portions of the portfolio more susceptible to the impact of the COVID -19 pandemic were reduced. These reductions in qualitative components were partially offset by a $5 million increase related to the potential impact of Hurricane Ian.

The ACL for residential and other consumer segment increased by $2.4 million during the three months ended September 30, 2022, from 0.10% to 0.13% of loans. The increase in the ACL for this segment was primarily driven by the economic forecast, particularly a decline in the HPI and increases in forecasted mortgage and unemployment rates.

The ACL for the CRE portfolio sub-segment, including multi-family, non-owner occupied CRE and construction and land, decreased by $6.8 million during the three months ended September 30, 2022, from 0.57% to 0.44% of loans. The decrease in the ACL for CRE was driven mainly by a decrease in qualitative loss factors, and to a lesser extent, improved borrower financial performance, partially offset by an increase in quantitative loss factors. The increase in quantitative loss factors resulted from a decline in forecasted GDP, and increases in forecasted unemployment and interest rates, offset by improved rental and vacancy rates across asset classes.

The ACL for the commercial and industrial sub-segment, including owner-occupied commercial real estate, increased by $3.8 million during the three months ended September 30, 2022, from 0.99% to 1.01% of loans. The increase was primarily attributable to an increase in specific reserves and a deteriorating economic forecast, partially offset by a decrease in qualitative loss factors

The ACL for the BFG franchise finance portfolio segment increased by $1.9 million during the three months ended September 30, 2022, from 2.38% to 3.22% of loans primarily due to an increase in specific reserves.

The ACL for the BFG equipment finance portfolio segment decreased $0.8 million during the three months ended September 30, 2022, from 0.84% to 0.64% of loans, primarily due to risk rating updates.

54

The estimate of the ACL at September 30, 2022 was informed by economic scenarios published in September 2022, economic information provided by additional sources, information about borrower financial condition and collateral values and other relevant information. The economic forecast used in modeling the quantitative ACL as of September 30, 2022, was a third-party provided baseline forecast. Some of the assumptions and data points informing the reasonable and supportable economic forecast used in estimating the quantitative ACL at September 30, 2022 included:

•Labor market assumptions, which reflected national unemployment at 3.7% for the fourth quarter of 2022, and 4.1% and 3.8% by the end of 2023 and 2024, respectively;

•Annualized growth in GDP at 0.6% for the fourth quarter of 2022, and 1.4% and 2.6% for 2023 and 2024, respectively;

•S&P 500 bottoming out in the fourth quarter of 2022 with a decline of 14.3%, and forecasting gains of 5% and 1.6% by end of 2023 and 2024, respectively.

•HPI growth of 5.7% in 2022, and declines of 3.3% and 1.7% by the end of 2023 and 2024, respectively.

Additional variables and assumptions not explicitly stated, including but not limited to residential and commercial property forecasts, also contributed to the overall impact economic conditions and the economic forecast had on the ACL estimate. Furthermore, while the variables presented above are at the national level, many of the variables are regionalized at the market and submarket level in the models.

Borrowings

In addition to deposits, we utilize FHLB advances as a funding source; the advances provide us with additional flexibility in managing both term and cost of funding and in managing interest rate risk. FHLB advances are secured by qualifying residential first mortgage and commercial real estate loans, and MBS. The following table presents information about the contractual balance of outstanding FHLB advances as of September 30, 2022 (dollars in thousands):

	Amount		Weighted Average Rate
Maturing in:
2022 - One month or less	$	4,095,000	2.83	%

Liquidity and Capital Resources

Liquidity involves our ability to generate adequate funds to support planned interest earning asset growth, meet deposit withdrawal and credit line usage requests, maintain reserve requirements, conduct routine operations, pay dividends, service outstanding debt and meet other contractual obligations.

BankUnited's ongoing liquidity needs have historically been met primarily by cash flows from operations, deposit growth, the investment portfolio and FHLB advances. FRB discount window borrowings provide an additional source of contingent liquidity. For the nine months ended September 30, 2022 and 2021, net cash provided by operating activities was $1.3 billion and $953 million, respectively.

Available liquidity includes cash, borrowing capacity at the Federal Home Loan Bank of Atlanta and the Federal Reserve Discount Window, Federal Funds lines of credit and unpledged agency securities. Additional sources of liquidity include cash flows from operations, wholesale deposits, cash flow from the Bank's amortizing securities and loan portfolios, and the sale of investment securities. Management also has the ability to exert substantial control over the rate and timing of loan production, and resultant requirements for liquidity to fund new loans.

The ALM policy establishes limits or operating thresholds and guidelines for a number of measures of liquidity which are typically monitored monthly by the ALCO and quarterly by the Board of Directors. The primary measures used to dimension liquidity risk are the ratio of available liquidity to volatile liabilities and a liquidity stress test coverage ratio. Other measures employed to monitor and manage liquidity include but are not limited to a 30-day total liquidity ratio, a one-year liquidity ratio, a wholesale funding ratio, concentrations of large deposits, a measure of on-balance sheet available liquidity, the ratio of FHLB advances to total assets and the ratio of non-interest bearing deposits to total deposits, which is reflective of the quality and cost, rather than the quantity, of available liquidity. At September 30, 2022, BankUnited was in compliance with the limits prescribed by the ALM policy.

The ALM policy stipulates that BankUnited’s liquidity is within policy limits if the available liquidity/volatile liabilities ratio and liquidity stress test ratios exceed 100%. At September 30, 2022, BankUnited’s available liquidity/volatile liabilities ratio was 222% and the liquidity stress test ratio was 168%. The Company has a comprehensive contingency liquidity funding plan and conducts a quarterly liquidity stress test, the results of which are reported to the risk committee of the Board of Directors.

As a holding company, BankUnited, Inc. is a corporation separate and apart from its banking subsidiary, and therefore, provides for its own liquidity. BankUnited, Inc.’s main sources of funds include management fees and dividends from the Bank, access to capital markets and, to a lesser extent, its own securities portfolio. There are regulatory limitations that may affect the ability of the Bank to pay dividends to BankUnited, Inc. Management believes that such limitations will not impact our ability to meet our ongoing near-term cash obligations.

Macro factors, including the initiation of quantitative tightening by the Fed, have recently led to reduced deposit levels across the banking system. BankUnited's total deposits declined by $1.1 billion during the quarter ended September 30, 2022, and there is uncertainty as to the future impact of monetary policy on deposit levels both system-wide and at BankUnited. We believe that we have sufficient on-balance sheet and contingent liquidity, through the sources described above, to satisfy our liquidity needs and cash requirements over the next twelve months.

Pursuant to the FDIA, the federal banking agencies have adopted regulations setting forth a five-tier system for measuring the capital adequacy of the financial institutions they supervise. At September 30, 2022 and December 31, 2021, the Company and the Bank had capital levels that exceeded both the regulatory well-capitalized guidelines and all internal capital ratio targets.

(1) There is no Tier 1 leverage ratio component in the definition of a well-capitalized bank holding company.

Upon adoption of ASU 2016-13 on January 1, 2020, the Company elected the option to temporarily delay the effects of CECL on regulatory capital for two years, followed by a three-year transition period.

We believe we are well positioned, from a capital perspective, to withstand a severe downturn in the economy. We continue to evolve our stress testing framework and adapt it to evolving macro-economic conditions as necessary. The majority of our commercial portfolio is subject to quarterly stress test analysis. On an annual basis, we also run a rigorous stress test of our entire balance sheet and, where applicable, we incorporate considerations for evolving macro-economic themes.

We have an active shelf registration statement on file with the SEC that allows the Company to periodically offer and sell in one or more offerings, individually or in any combination, our common stock, preferred stock and other non-equity securities. The shelf registration provides us with flexibility in issuing capital instruments and enables us to more readily access the capital markets as needed to pursue future growth opportunities and to ensure continued compliance with regulatory capital requirements. Our ability to issue securities pursuant to the shelf registration is subject to market conditions.

Interest Rate Risk

A principal component of the Company’s risk of loss arising from adverse changes in the fair value of financial instruments, or market risk, is interest rate risk, including the risk that assets and liabilities with similar re-pricing characteristics may not reprice at the same time or to the same degree. A primary objective of the Company’s asset/liability management activities is to maximize net interest income, while maintaining acceptable levels of interest rate risk. The ALCO is responsible for establishing policies to manage exposure to interest rate risk, and to ensure procedures are established to monitor compliance with these policies. The policies established by the ALCO are approved at least annually by the Board of Directors or its Risk Committee.

Management believes that the simulation of net interest income in different interest rate environments provides the most meaningful measure of interest rate risk. Income simulation analysis is designed to capture not only the potential of all assets and liabilities to mature or reprice, but also the probability that they will do so. Income simulation also attends to the relative interest rate sensitivities of these items, and projects their behavior over an extended period of time. Finally, income simulation permits management to assess the probable effects on the balance sheet not only of changes in interest rates, but also of proposed strategies for responding to them.

The income simulation model analyzes interest rate sensitivity by projecting net interest income over twelve and twenty-four month periods in a most likely rate scenario based on consensus forward interest rate curves versus net interest income in alternative rate scenarios. Management continually reviews and refines its interest rate risk management process in response to changes in the interest rate environment, the economic climate and observed customer behavior. Currently, our interest rate risk policy framework is based on modeling instantaneous rate shocks of plus and minus 100, 200, 300 and 400 basis point shifts.

58

We also model a variety of yield curve slope and dynamic balance sheet scenarios. We continually evaluate the scenarios being modeled with a view toward adapting them to changing economic conditions, expectations and trends.

The following table presents the impact on forecasted net interest income compared to a "most likely" scenario in parallel rate shock scenarios of plus 100, 200, 300 and 400 basis points at September 30, 2022 and December 31, 2021, as well as minus 100 and 200 basis points scenario at September 30, 2022. At September 30, 2022, the most likely rate scenario incorporated a bear flattening yield curve and floored all indices at 0%. We did not apply a falling rate scenario at December 31, 2021 due to the low prevailing interest rate environment at that time.

	Down 200		Down 100		Plus 100		Plus 200		Plus 300		Plus 400
Model Results at September 30, 2022 - increase (decrease)
In year 1	(8.1)	%	(4.0)	%	1.2	%	1.3	%	1.6	%	1.7	%
In year 2	(11.4)	%	(4.2)	%	3.4	%	5.5	%	7.2	%	7.5	%
Model Results at December 31, 2021 - increase
In year 1	N/A		N/A		2.5	%	3.9	%	4.3	%	4.2	%
In year 2	N/A		N/A		6.6	%	11.5	%	15.8	%	20.4	%

Management also simulates changes in EVE in various interest rate environments. The following table illustrates the modeled change in EVE in the indicated scenarios at September 30, 2022 and December 31, 2021:

	Down 200		Down 100		Plus 100		Plus 200		Plus 300		Plus 400
Model Results at September 30, 2022 - increase (decrease):	2.9	%	3.0	%	(3.0)	%	(7.2)	%	(10.9)	%	(14.2)	%
Model Results at December 31, 2021 - increase (decrease):	N/A		N/A		0.4	%	(1.0)	%	(3.2)	%	(5.0)	%

Many assumptions were used by the Company to calculate the impact of changes in interest rates, including the change in rates. Actual results may not be similar to the Company’s projections due to several factors including the timing and frequency of rate changes, market conditions, changes in depositor behavior and loan prepayment speeds and the shape of the yield curve. Actual results may also differ due to the Company’s actions, if any, in response to changing rates and conditions.

Derivative Financial Instruments

Interest rate derivatives designated as cash flow or fair value hedging instruments are one of the tools we use to manage interest rate risk. These derivative instruments are used to mitigate exposure to changes in interest cash flows on variable rate liabilities and to changes in the fair value of fixed rate financial instruments, in each case caused by fluctuations in benchmark interest rates, as well as to manage duration of liabilities. The fair value of derivative instruments designated as hedges is included in other assets and other liabilities in our consolidated balance sheets. Changes in fair value of derivative instruments designated as cash flow hedges are reported in accumulated other comprehensive income. Changes in the fair value of derivative instruments designated as fair value hedges are recognized in earnings, as is the offsetting gain or loss on the hedged item. At September 30, 2022, outstanding interest rate swaps, caps and collars designated as cash flow hedges had an aggregate notional amount of $2.1 billion and outstanding interest rate swaps designated as fair value hedges had an aggregate notional amount of $100 million.

Interest rate swaps and caps not designated as hedges had an aggregate notional amount of $3.9 billion at September 30, 2022. These interest rate swaps and caps were entered into as accommodations to certain of our commercial borrowers. To mitigate interest rate risk associated with these derivatives, the Company enters into offsetting derivative positions with primary dealers.

See Note 6 to the consolidated financial statements for additional information about derivative financial instruments.

LIBOR Transition

The Company has implemented and is in the process of executing a detailed plan to facilitate the transition from LIBOR to alternative reference rates, with SOFR being the preferred alternative to LIBOR. A discussion of the Company's LIBOR transition plan and activities appears in the "LIBOR Transition" section in the MD&A of the Company's 2021 Annual Report on Form 10-K.

The following table presents information about the Company's exposure to instruments that reference LIBOR as of September 30, 2022 (in thousands):

	Maturing

Investment securities	$	—	$	3,821,646	$	3,821,646

Impact of the COVID-19 Pandemic

A detailed discussion of the effects the COVID-19 pandemic had during 2021 on our Company appears in the "Impact of the COVID-19 Pandemic and Our Response" section in the MD&A of the Company's 2021 Annual Report on Form 10-K.

2021 and 2022 were characterized broadly by recovery of the U.S. economy from the impact of the COVID-19 pandemic. The actual and expected impact of the pandemic on our financial condition and results of operations continues to decline. Levels of criticized and classified assets remain elevated at September 30, 2022, when compared to pre-pandemic levels although they continue to trend downward. The composition of the balance sheet at September 30, 2022 and corresponding levels of net interest income reflect the opportunity cost of the decline in commercial loans and the increase in residential loans and securities that occurred over the course of the pandemic. Historically, commercial loans have generally tended to be higher yielding assets than residential loans and securities. During the first quarter of 2022, we welcomed our employees back to the office, adopting a hybrid work model for most non-branch employees. This model will likely continue to evolve over the near to medium term.

Non-GAAP Financial Measures

PPNR is a non-GAAP financial measure. Management believes this measure is relevant to understanding the performance of the Company attributable to elements other than the provision for credit losses and the ability of the Company to generate earnings sufficient to cover estimated credit losses, particularly in view of the volatility of the provision for credit losses. This measure also provides a meaningful basis for comparison to other financial institutions since it is commonly employed and is a measure frequently cited by investors and analysts. The following table reconciles the non-GAAP financial measurement of PPNR to the comparable GAAP financial measurement of income before income taxes for the periods indicated (in thousands):

	Three Months Ended September 30, 2022		Three Months Ended June 30, 2022		Three Months Ended September 30, 2021
Income before income taxes (GAAP)	$	117,083	$	87,468	$	114,400
Plus: Provision for (recovery of) credit losses	3,720		23,996		(11,842)
PPNR (non-GAAP)	$	120,803	$	111,464	$	102,558

Tangible book value per common share is a non-GAAP financial measure. Management believes this measure is relevant to understanding the capital position and performance of the Company. Disclosure of this non-GAAP financial measure also provides a meaningful basis for comparison to other financial institutions as it is a metric commonly used in the banking industry. The following table reconciles the non-GAAP financial measurement of tangible book value per common share to the comparable GAAP financial measurement of book value per common share at the dates indicated (in thousands except share and per share data): 

	September 30, 2022		December 31, 2021
Total stockholders’ equity	$	2,480,985	$	3,037,761
Less: goodwill and other intangible assets	77,637		77,637
Tangible stockholders’ equity	$	2,403,348	$	2,960,124
Common shares issued and outstanding	77,599,408		85,647,986
Book value per common share	$	31.97	$	35.47
Tangible book value per common share	$	30.97	$	34.56

Item 3.  Quantitative and Qualitative Disclosures About Market Risk

See the section entitled “Interest Rate Risk” included in Item 2. “Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

As of the end of the period covered by this Form 10-Q, we carried out an evaluation under the supervision and with the participation of our management, including the Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures as defined in Exchange Act Rules 13a-15(e) and 15d-15(e). Based upon that evaluation, the Chief Executive Officer and the Chief Financial Officer concluded that our disclosure controls and procedures were effective.

During the quarter ended September 30, 2022, there were no changes in the Company's internal control over financial reporting, that materially affected, or are reasonably likely to materially affect, the Company's internal control over financial reporting.

PART II.  OTHER INFORMATION

Item 1.   Legal Proceedings

 The Company is involved as plaintiff or defendant in various legal actions arising in the normal course of business. In the opinion of management, based upon currently available information and the advice of legal counsel, the likelihood is remote

61

that the impact of these proceedings, either individually or in the aggregate, would be material to the Company’s consolidated financial position, results of operations or cash flows.

Item 1A.   Risk Factors

Geopolitical factors such as the conflict between Russia and Ukraine or similar events could negatively impact our business and results of operations.

We are monitoring the impact of the conflict between Russia and Ukraine on our business. While we do not currently expect that the conflict will have a direct material impact on our business, financial condition or results of operations, collateral effects of the geopolitical instability, such as the imposition of sanctions against Russia and Russia’s response to such sanctions, including retaliatory acts like cyber-attacks and sanctions against other countries, or escalation or further spread of the conflict could adversely affect the global economy or domestic markets, including ours.

Item 2.   Unregistered Sales of Equity Securities and Use of Proceeds

	Issuer Purchases of Equity Securities
Period	Total number of shares purchased(1)	Average price paid per share		Total number of shares purchased as part of publicly announced plans or programs	Maximum number (or approximate dollar value) of shares that may yet be purchased under the plans or programs (2)(3)

Basis of Presentation and Summary of Significant Accounting Policies

Note 1    Basis of Presentation and Summary of Significant Accounting Policies

BankUnited, Inc. is a national bank holding company with one wholly-owned subsidiary, BankUnited, collectively, the Company. BankUnited, a national banking association headquartered in Miami Lakes, Florida, provides a full range of banking and related services to individual and corporate customers through 58 banking centers located in 12 Florida counties, 4 banking centers located in the New York metropolitan area, and 1 banking center located in Dallas, Texas at September 30, 2022. The Bank also offers certain commercial lending and deposit products through national platforms and regional wholesale banking offices.

The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X of the SEC. Accordingly, these do not include all of the information and footnotes required for a fair presentation of financial position, results of operations and cash flows in conformity with GAAP and should be read in conjunction with the Company’s consolidated financial statements and the notes thereto appearing in BKU’s Annual Report on Form 10-K for the year ended December 31, 2021 filed with the SEC. In the opinion of management, all adjustments, consisting of normal recurring adjustments, considered necessary for a fair presentation have been included. Operating results for the three and nine months ended September 30, 2022 are not necessarily indicative of the results that may be expected in future periods.

The Company has a single operating segment and thus a single reportable segment. While management monitors the revenue streams of its various business units, the business units serve a similar base of primarily commercial clients, providing a similar range of products and services, managed through similar processes and platforms. The Company’s chief operating decision maker makes company-wide resource allocation decisions and assessments of performance based on a collective assessment of the Company’s operations.

Accounting Estimates

In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, and expenses and disclosures of contingent assets and liabilities. Actual results could differ significantly from these estimates.

The most significant estimate impacting the Company's consolidated financial statements is the ACL.

New Accounting Pronouncements Adopted During the Nine Months Ended September 30, 2022

ASU No. 2020-06, Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity’s Own Equity (Subtopic 815-40). This ASU simplifies the accounting for convertible debt and convertible preferred stock by reducing the number of accounting models for these instruments, resulting in fewer embedded conversion features being separately recognized from the host contract. Additionally, this ASU revises the criteria for determining whether contracts in an entity's own equity meet the scope exception from derivative accounting, which will change the population of contracts that are recognized as assets or liabilities. The amendments in this ASU also revise certain aspects of the guidance on calculating earnings per share with respect to convertible instruments and instruments that may be settled in the entity's own shares. The Company adopted this ASU on January 1, 2022, with no material impact on the Company's consolidated financial position, results of operations, and cash flows.

ASU No. 2022-01, Fair Value Hedging—Portfolio Layer Method (Topic 815). This ASU expands the portfolio layer method of hedge accounting prescribed in ASU No. 2017-12 to allow multiple hedged layers of a single closed portfolio and to include portfolios of both prepayable and non-prepayable financial assets. This scope expansion is consistent with the FASB’s efforts to simplify hedge accounting and allows entities to apply the same accounting method to similar hedging strategies. The ASU also specifies eligible hedging instruments in a single-layer hedge, provides additional guidance on accounting and disclosure of hedge basis adjustments and specifies how hedge basis adjustments should be considered in determining credit losses for assets in the designated closed portfolio. This ASU is effective for public business entities for interim and annual periods in fiscal years beginning after December 15, 2022. The Company adopted this ASU upon its release in March 2022 with no material impact on the Company's consolidated financial position, results of operations, and cash flows.

Accounting Pronouncements Not Yet AdoptedASU No. 2022-02, Financial Instruments—Credit Losses (Topic 326). This ASU eliminates the accounting guidance for TDRs by creditors in Subtopic 310-40, Receivables - Troubled Debt Restructurings by Creditors. The ASU enhances disclosure requirements for certain loan refinancings and restructurings by creditors when a borrower is experiencing financial difficulty, updates certain requirements related to accounting for credit losses under ASC 326 and requires disclosure of current-period gross write offs of financing receivables by year of origination. The ASU is effective for the Company for interim and annual periods in fiscal years beginning after December 15, 2022. The Company is currently completing its evaluation of the impact of adoption of this ASU, however, the impact of adoption on the Company's consolidated financial position, results of operations, and cash flows is not expected to be material. Adoption will lead to additional and revised disclosures in the Company's financial statements

The Company monitors its investment securities available for sale for credit loss impairment on an individual security basis. No securities were determined to be credit loss impaired during the three and nine months ended September 30, 2022 and 2021. At September 30, 2022, the Company did not have an intent to sell securities that were in unrealized loss positions and it was not more likely than not that the Company would be required to sell these securities before recovery of the amortized cost basis, which may be at maturity. In making this determination, the Company considered its current and projected liquidity position, its investment policy as to permissible holdings and concentration limits, regulatory requirements and other relevant factors.

At September 30, 2022, 579 securities available for sale were in unrealized loss positions. The amount of impairment related to 96 of these securities was considered insignificant both individually and in the aggregate, totaling approximately $0.9 million and no further analysis with respect to these securities was considered necessary.

The basis for concluding that AFS securities were not credit loss impaired and no ACL was considered necessary at September 30, 2022 is further discussed below.

Unrealized losses were generally attributable to rising interest rates and widening spreads related to the Federal Reserve's quantitative tightening and benchmark interest rate increases. Continuing uncertainty with respect to the trajectory of the economy and geopolitical events have also led to market uncertainty, producing some yield curve dislocations.

U.S. Government Agency and Government Sponsored Enterprise Securities

At September 30, 2022, five U.S. treasury, 149 U.S. Government agency and sponsored enterprise residential MBS, 27 U.S. Government agency and sponsored enterprise commercial MBS, and 15 SBA securities were in unrealized loss positions. The timely payment of principal and interest on these securities is explicitly or implicitly guaranteed by the U.S. Government. As such, there is an assumption of zero credit loss and the Company expects to recover the amortized cost basis of these securities.

Private Label Securities:

None of the impaired private label securities had missed principal or interest payments or had been downgraded by a NRSRO at September 30, 2022. The Company performed an analysis comparing the present value of cash flows expected to be collected to the amortized cost basis of impaired securities. This analysis was based on a scenario that we believe to be generally more conservative than our reasonable and supportable economic forecast at September 30, 2022, and incorporated assumptions about voluntary prepayment rates, collateral defaults, delinquencies, severity and other relevant factors as described further below. Our analysis also considered the structural characteristics of each security and the level of credit enhancement provided by that structure.

Private label residential MBS and CMOs

At September 30, 2022, 115 private label residential MBS and CMOs were in unrealized loss positions. Our analysis of cash flows expected to be collected on these securities incorporated assumptions about collateral default rates, voluntary prepayment rates, loss severity, delinquencies and recovery lag. In developing those assumptions, we took into account collateral quality measures such as FICO, LTV, documentation, loan type, property type, agency availability criteria and performing status. We also regularly monitor sector data including home price appreciation, forbearance, delinquency and prepay trends as well as other economic data that could be indicative of stress in the sector. Our September 30, 2022 analysis projected weighted average collateral losses for impaired securities in this category of 3% compared to weighted average credit support of 18%. As of September 30, 2022, 94% of impaired securities in this category, based on carrying value, were externally rated AAA, 1% were rated AA and 5% were rated A.

Private label commercial MBS

At September 30, 2022, 109 private label commercial MBS were in unrealized loss positions. Our analysis of cash flows expected to be collected on these securities incorporated assumptions about collateral default rates, voluntary prepayment rates, loss severity, delinquencies and recovery lag. In developing those assumptions, we took into account collateral quality and type, loan size, loan purpose and other qualitative factors. We also regularly monitor collateral watch lists, bankruptcy data, defeasance data, special servicing trends, delinquency and other economic data that could be indicative of stress in the sector. Our September 30, 2022 analysis projected weighted average collateral losses for impaired securities in this category of 7% compared to weighted average credit support of 43%. As of September 30, 2022, 84% of impaired securities in this category, based on carrying value, were externally rated AAA, 12% were rated AA and 4% were rated A.

Single family real estate-backed securities

At September 30, 2022, 16 single family rental real estate-backed securities were in unrealized loss positions. Our analysis of cash flows expected to be collected on these securities incorporated assumptions about collateral default rates, loss severity, delinquencies and recovery lag. We regularly monitor sector data including home price appreciation, forbearance, delinquency and prepay trends as well as other economic data that could be indicative of stress in the sector. Our September 30, 2022 analysis projected weighted average collateral losses for this category of 8% compared to weighted average credit support of 50%. As of September 30, 2022, 63% of impaired securities in this category, based on carrying value, were externally rated AAA, 14% were rated AA and one security was not externally rated.

Collateralized loan obligations

At September 30, 2022, 26 collateralized loan obligations were in unrealized loss positions. Our analysis of cash flows expected to be collected on these securities incorporated assumptions about collateral default rates, loss severity, and delinquencies, calibrated to take into account idiosyncratic risks associated with the underlying collateral. In developing those assumptions, we took into account each sector’s performance pre-, during and post the 2008 financial crisis. We regularly engage with bond managers to monitor trends in underlying collateral including potential downgrades and subsequent cash flow diversions, liquidity, ratings migration, and any other relevant developments. Our September 30, 2022 analysis projected weighted average collateral losses for impaired securities in this category of 9% compared to weighted average credit support of 42%. As of September 30, 2022, 77% of the impaired securities in this category, based on carrying value, were externally rated AAA, 19% were rated AA and 4% were rated A.

Non-mortgage asset-backed securities

At September 30, 2022, seven non-mortgage asset-backed securities were in unrealized loss positions. These securities are backed by student loan collateral. Our analysis of cash flows expected to be collected on these securities incorporated assumptions about collateral default rates, loss severity, delinquencies, voluntary prepayment rates and recovery lag. In developing assumptions, we took into account collateral type, delineated by whether collateral consisted of loans to borrowers in school, refinancing, or a mixture. Our September 30, 2022 analysis projected weighted average collateral losses for impaired securities in this category of 4% compared to weighted average credit support of 23%. As of September 30, 2022, 51% of the impaired securities in this category, based on carrying value, were externally rated AAA, and 49% were rated AA.

State and Municipal ObligationsAt September 30, 2022, 14 state and municipal obligations were in unrealized loss positions. Our analysis of potential credit loss impairment for these securities incorporates a quantitative measure of the underlying obligor's credit worthiness provided by a third-party vendor as well as other relevant qualitative considerations. As of September 30, 2022, 61% of the impaired securities in this category, based on carrying value, were externally rated AAA, 16% were rated AA

Allowance for credit losses

The ACL was determined utilizing a 2-year reasonable and supportable forecast period. The quantitative portion of the ACL was determined using a single third-party provided economic scenario. The qualitative component was informed by alternate scenarios. Activity in the ACL is summarized below for the periods indicated (in thousands):

The ACL increased by $4.2 million at September 30, 2022 compared to December 31, 2021, remaining largely consistent as a percentage of total loans. The provision for credit losses for the nine months ended September 30, 2022 was largely offset by net charge-offs. The more significant factors impacting the provision for credit losses for the nine months ended September 30, 2022, included increases in specific reserves and qualitative loss factors, loan growth, the decline in criticized and classified assets, and changes in certain assumptions including prepayment speeds.

The following table presents the components of the provision for (recovery of) credit losses for the periods indicated (in thousands):

Credit quality information

Credit quality of loans held for investment is continuously monitored by dedicated residential credit risk management and commercial portfolio management functions. The Company also has a workout and recovery department that monitors the credit quality of criticized and classified loans and an independent internal credit review function.

Credit quality indicators for residential loans

Management considers delinquency status to be the most meaningful indicator of the credit quality of residential and other consumer loans, other than government insured residential loans. Delinquency statistics are updated at least monthly. LTV and FICO scores are also important indicators of credit quality for 1-4 single family residential loans other than government insured loans. FICO scores are generally updated at least annually, and were most recently updated in the third quarter of 2022. LTVs are typically at origination since we do not routinely update residential appraisals. Substantially all of the government insured residential loans are government insured buyout loans, which the Company buys out of GNMA securitizations upon default. For these loans, traditional measures of credit quality are not particularly relevant considering the guaranteed nature of the loans and the underlying business model. Factors that impact risk inherent in the residential portfolio segment include national and regional economic conditions such as levels of unemployment and wages, as well as residential property values.

Credit quality indicators for commercial loans

Factors that impact risk inherent in commercial portfolio segments include but are not limited to levels of economic activity, health of the national and regional economy, industry trends, patterns of and trends in customer behavior that influence demand for our borrowers' products and services, and commercial real estate values. Internal risk ratings are considered the most meaningful indicator of credit quality for commercial loans. Internal risk ratings are generally indicative of the likelihood that a borrower will default, are a key factor influencing the level and nature of ongoing monitoring of loans and may impact the estimation of the ACL. Internal risk ratings are updated on a continuous basis. Generally, relationships with balances in excess of defined thresholds, ranging from $1 million to $3 million, are re-evaluated at least annually and more frequently if circumstances indicate that a change in risk rating may be warranted. Loans exhibiting potential credit weaknesses that deserve management’s close attention and that could result in deterioration of repayment prospects at some future date if not checked or corrected are categorized as special mention. Loans with well-defined credit weaknesses, including payment defaults, declining collateral values, frequent overdrafts, operating losses, increasing balance sheet leverage, inadequate cash flow from current

operations, project cost overruns, unreasonable construction delays, past due real estate taxes or exhausted interest reserves, are assigned an internal risk rating of substandard. A loan with a weakness so severe that collection in full is highly questionable or improbable, but because of certain reasonably specific pending factors has not been charged off, will be assigned an internal risk rating of doubtful.

Collateral for construction and land loans is typically residential or commercial real estate. Collateral for commercial and industrial loans generally consists of equipment, accounts receivable, inventory and other business assets; owner-occupied commercial real estate loans may also be collateralized by these types of assets. Bridge franchise finance loans may be collateralized by franchise value or by equipment. Bridge equipment finance loans are secured by the financed equipment. Residential loans are collateralized by residential real estate. There have been no significant changes to the extent to which collateral secures collateral dependent loans during the nine months ended September 30, 2022.

Foreclosure of residential real estate

The recorded investment in residential loans in the process of foreclosure was $451 million, of which $443 million was government insured, at September 30, 2022 and $208 million, of which $202 million was government insured, at December 31, 2021. The carrying amount of foreclosed residential real estate included in other assets in the accompanying consolidated balance sheet was insignificant at September 30, 2022 and December 31, 2021.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivatives and Hedging Activities

Note 6    Derivatives and Hedging Activities

The Company has entered into interest rate swaps, caps and collars designated as cash flow hedges with the objective of limiting the variability of interest payment cash flows. The Company has also entered into interest rate swaps designated as fair value hedges designed to hedge changes in the fair value of outstanding fixed rate instruments caused by fluctuations in the benchmark interest rate.

The Company enters into interest rate derivative contracts with certain of its commercial borrowers to enable those borrowers to manage their exposure to interest rate fluctuations. To mitigate interest rate risk associated with these derivative contracts, the Company enters into offsetting derivative contract positions with primary dealers. These interest rate derivative contracts are not designated as hedging instruments; therefore, changes in the fair value of these derivatives are recognized immediately in earnings. For the three and nine months ended September 30, 2022 and 2021, the impact on earnings related to changes in fair value of these derivatives was not material.

The Company may be exposed to credit risk in the event of non-performance by the counterparties to its interest rate derivative agreements. The Company assesses the credit risk of its financial institution counterparties by monitoring publicly available credit rating and financial information. The Company manages dealer credit risk by entering into interest rate derivatives only with primary and highly rated counterparties, the use of ISDA master agreements, central clearing mechanisms and counterparty limits. The agreements contain bilateral collateral arrangements with the amount of collateral to be posted generally governed by the settlement value of outstanding swaps. The Company manages the risk of default by its commercial borrower counterparties through its normal loan underwriting and credit monitoring policies and procedures. The Company does not currently anticipate any significant losses from failure of interest rate derivative counterparties to honor their obligations.

The CME legally characterizes variation margin payments for centrally cleared derivatives as settlements of the derivatives' exposures rather than collateral. As a result, the variation margin payment and the related derivative instruments are considered a single unit of account for accounting and financial reporting purposes. The Company's clearing agent for interest rate derivative contracts centrally cleared through the CME settles the variation margin daily with the CME; therefore, those interest rate derivative contracts the Company clears through the CME are reported at a fair value of zero at both September 30, 2022 and December 31, 2021.

Fair Value Disclosures [Abstract]

Fair Value Measurements

Note 8    Fair Value Measurements

Assets and liabilities measured at fair value on a recurring basis

The following is a description of the methodologies used to estimate the fair values of assets and liabilities measured at fair value on a recurring basis and the level within the fair value hierarchy in which those measurements are typically classified.

Investment securities available for sale and marketable equity securities—Fair value measurements are based on quoted prices in active markets when available; these measurements are classified within level 1 of the fair value hierarchy. These securities typically include U.S. Treasury securities and certain preferred stocks. If quoted prices in active markets are not available, fair values are estimated using quoted prices of securities with similar characteristics, quoted prices of identical securities in less active markets, discounted cash flow techniques, or matrix pricing models. These securities are generally classified within level 2 of the fair value hierarchy and include U.S. Government agency securities, U.S. Government agency and sponsored enterprise MBS, preferred stock investments for which level 1 valuations are not available, non-mortgage asset-backed securities, single family real estate-backed securities, private label residential MBS and CMOs, private label commercial MBS, collateralized loan obligations and state and municipal obligations. Pricing of these securities is generally primarily spread driven. Observable inputs that may impact the valuation of these securities include benchmark yield curves, credit spreads, reported trades, dealer quotes, bids, issuer spreads, current rating, historical constant prepayment rates, historical voluntary prepayment rates, structural and waterfall features of individual securities, published collateral data, and for certain securities, historical constant default rates and default severities.

The Company uses third-party pricing services in determining fair value measurements for investment securities. To obtain an understanding of the methodologies and assumptions used, management reviews written documentation provided by the pricing services, conducts interviews with valuation desk personnel and reviews model results and detailed assumptions used to value selected securities as considered necessary. Management has established a robust price challenge process that includes a review by the treasury front office of all prices provided on a monthly basis. Any price evidencing unexpected month over month fluctuations or deviations from expectations is challenged. If considered necessary to resolve any discrepancies, a price will be obtained from an additional independent valuation source. The Company does not typically adjust the prices provided, other than through this established challenge process. The results of price challenges are subject to review by executive management. Any price discrepancies are resolved based on careful consideration of the assumptions and inputs employed by each of the pricing sources.

Derivative financial instruments—Fair values of interest rate swaps, caps and collars are determined using widely accepted discounted cash flow modeling techniques. These discounted cash flow models use projections of future cash payments and receipts that are discounted at mid-market rates. Observable inputs that may impact the valuation of these instruments include benchmark swap rates and benchmark forward yield curves. These fair value measurements are generally classified within level 2 of the fair value hierarchy.

Assets and liabilities measured at fair value on a non-recurring basis

Following is a description of the methodologies used to estimate the fair values of assets and liabilities that may be measured at fair value on a non-recurring basis, and the level within the fair value hierarchy in which those measurements are typically classified. 

Collateral dependent loans and OREO—The carrying amount of collateral dependent loans is typically based on the fair value of the underlying collateral, which may be real estate, enterprise value or other business assets, less estimated costs to sell when repayment is expected to come from the sale of the collateral. The carrying value of OREO is initially measured based on the fair value of the real estate acquired in foreclosure and subsequently adjusted to the lower of cost or estimated fair value, less estimated cost to sell. Fair values of real estate collateral and OREO are typically based on third-party real estate appraisals which utilize market and income approaches to valuation incorporating both observable and unobservable inputs.

Fair value measurements related to collateral dependent loans and OREO are generally classified within level 3 of the fair value hierarchy.

Operating lease equipment—Fair values of impaired operating lease equipment are typically based upon discounted cash flow analyses, considering expected lease rates and estimated end of life residual values, typically obtained from independent appraisals. These fair value measurements are classified within level 3 of the fair value hierarchy.

The following table presents the net carrying value of assets classified within level 3 of the fair value hierarchy at the dates indicated, for which non-recurring changes in fair value were recorded during the period then ended (in thousands):

Commitments and Contingencies

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingencies

Note 9    Commitments and Contingencies 

The Company issues off-balance sheet financial instruments to meet the financing needs of its customers. These financial instruments include commitments to fund loans, unfunded commitments under existing lines of credit, and commercial and standby letters of credit. These commitments expose the Company to varying degrees of credit and market risk which are essentially the same as those involved in extending loans to customers, and are subject to the same credit policies used in underwriting loans. Collateral may be obtained based on the Company’s credit evaluation of the counterparty. The Company’s maximum exposure to credit loss is represented by the contractual amount of these commitments.

Commitments to fund loans

These are agreements to lend funds to customers as long as there is no violation of any condition established in the contract. Commitments to fund loans generally have fixed expiration dates or other termination clauses and may require payment of a fee. Many of these commitments are expected to expire without being funded and, therefore, the total commitment amounts do not necessarily represent future liquidity requirements. 

Unfunded commitments under lines of credit

Unfunded commitments under lines of credit include commercial, commercial real estate and consumer lines of credit to existing customers, for many of which additional extensions of credit are subject to borrowing base requirements. Some of these commitments may mature without being fully funded, so may not necessarily represent future liquidity requirements. 

Commercial and standby letters of credit

Letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. These letters of credit are primarily issued to support trade transactions or guarantee arrangements. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers. 

Total lending related commitments outstanding at September 30, 2022 were as follows (in thousands):

Commitments to fund loans	$	618,765
Unfunded commitments under lines of credit	5,386,312
Commercial and standby letters of credit	113,730
	$	6,118,807

Legal Proceedings

The Company is involved as plaintiff or defendant in various legal actions arising in the normal course of business. In the opinion of management, based upon advice of legal counsel, the likelihood is remote that the impact of these proceedings, either individually or in the aggregate, would be material to the Company’s consolidated financial position, results of operations or cash flows.

Accounting Estimates

Accounting Estimates

In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, and expenses and disclosures of contingent assets and liabilities. Actual results could differ significantly from these estimates.

The most significant estimate impacting the Company's consolidated financial statements is the ACL.

New Accounting Pronouncements Adopted During the Nine Months Ended September 30, 2022 and Accounting Pronouncements Not Yet Adopted

New Accounting Pronouncements Adopted During the Nine Months Ended September 30, 2022

ASU No. 2020-06, Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity’s Own Equity (Subtopic 815-40). This ASU simplifies the accounting for convertible debt and convertible preferred stock by reducing the number of accounting models for these instruments, resulting in fewer embedded conversion features being separately recognized from the host contract. Additionally, this ASU revises the criteria for determining whether contracts in an entity's own equity meet the scope exception from derivative accounting, which will change the population of contracts that are recognized as assets or liabilities. The amendments in this ASU also revise certain aspects of the guidance on calculating earnings per share with respect to convertible instruments and instruments that may be settled in the entity's own shares. The Company adopted this ASU on January 1, 2022, with no material impact on the Company's consolidated financial position, results of operations, and cash flows.

ASU No. 2022-01, Fair Value Hedging—Portfolio Layer Method (Topic 815). This ASU expands the portfolio layer method of hedge accounting prescribed in ASU No. 2017-12 to allow multiple hedged layers of a single closed portfolio and to include portfolios of both prepayable and non-prepayable financial assets. This scope expansion is consistent with the FASB’s efforts to simplify hedge accounting and allows entities to apply the same accounting method to similar hedging strategies. The ASU also specifies eligible hedging instruments in a single-layer hedge, provides additional guidance on accounting and disclosure of hedge basis adjustments and specifies how hedge basis adjustments should be considered in determining credit losses for assets in the designated closed portfolio. This ASU is effective for public business entities for interim and annual periods in fiscal years beginning after December 15, 2022. The Company adopted this ASU upon its release in March 2022 with no material impact on the Company's consolidated financial position, results of operations, and cash flows.

Accounting Pronouncements Not Yet AdoptedASU No. 2022-02, Financial Instruments—Credit Losses (Topic 326). This ASU eliminates the accounting guidance for TDRs by creditors in Subtopic 310-40, Receivables - Troubled Debt Restructurings by Creditors. The ASU enhances disclosure requirements for certain loan refinancings and restructurings by creditors when a borrower is experiencing financial difficulty, updates certain requirements related to accounting for credit losses under ASC 326 and requires disclosure of current-period gross write offs of financing receivables by year of origination. The ASU is effective for the Company for interim and annual periods in fiscal years beginning after December 15, 2022. The Company is currently completing its evaluation of the impact of adoption of this ASU, however, the impact of adoption on the Company's consolidated financial position, results of operations, and cash flows is not expected to be material. Adoption will lead to additional and revised disclosures in the Company's financial statements

The ACL increased by $4.2 million at September 30, 2022 compared to December 31, 2021, remaining largely consistent as a percentage of total loans. The provision for credit losses for the nine months ended September 30, 2022 was largely offset by net charge-offs. The more significant factors impacting the provision for credit losses for the nine months ended September 30, 2022, included increases in specific reserves and qualitative loss factors, loan growth, the decline in criticized and classified assets, and changes in certain assumptions including prepayment speeds.

The following table presents the components of the provision for (recovery of) credit losses for the periods indicated (in thousands):

Financing Receivable Credit Quality Indicators

FICO scores are generally updated at least annually, and were most recently updated in the third quarter of 2022. LTVs are typically at origination since we do not routinely update residential appraisals. Substantially all of the government insured residential loans are government insured buyout loans, which the Company buys out of GNMA securitizations upon default. For these loans, traditional measures of credit quality are not particularly relevant considering the guaranteed nature of the loans and the underlying business model. Factors that impact risk inherent in the residential portfolio segment include national and regional economic conditions such as levels of unemployment and wages, as well as residential property values.

Credit quality indicators for commercial loans

Factors that impact risk inherent in commercial portfolio segments include but are not limited to levels of economic activity, health of the national and regional economy, industry trends, patterns of and trends in customer behavior that influence demand for our borrowers' products and services, and commercial real estate values. Internal risk ratings are considered the most meaningful indicator of credit quality for commercial loans. Internal risk ratings are generally indicative of the likelihood that a borrower will default, are a key factor influencing the level and nature of ongoing monitoring of loans and may impact the estimation of the ACL. Internal risk ratings are updated on a continuous basis. Generally, relationships with balances in excess of defined thresholds, ranging from $1 million to $3 million, are re-evaluated at least annually and more frequently if circumstances indicate that a change in risk rating may be warranted. Loans exhibiting potential credit weaknesses that deserve management’s close attention and that could result in deterioration of repayment prospects at some future date if not checked or corrected are categorized as special mention. Loans with well-defined credit weaknesses, including payment defaults, declining collateral values, frequent overdrafts, operating losses, increasing balance sheet leverage, inadequate cash flow from current

operations, project cost overruns, unreasonable construction delays, past due real estate taxes or exhausted interest reserves, are assigned an internal risk rating of substandard. A loan with a weakness so severe that collection in full is highly questionable or improbable, but because of certain reasonably specific pending factors has not been charged off, will be assigned an internal risk rating of doubtful.
