NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - UNAUDITED
March 31, 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 62 banking centers located in 12 Florida counties and 4 banking centers located in the New York metropolitan area at March 31, 2022. The Bank also offers certain commercial lending and deposit products through national platforms.
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 months ended March 31, 2022 are not necessarily indicative of the results that may be expected in future periods.
The Company has a single reportable segment.
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 Three Months Ended March 31, 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 Adopted
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 has not completed 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 months ended March 31, 2022 and 2021. At March 31, 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 March 31, 2022, 419 securities available for sale were in unrealized loss positions. The amount of impairment related to 89 of these securities was considered insignificant both individually and in the aggregate, totaling approximately $0.7 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 March 31, 2022 is further discussed below.
Unrealized losses were generally attributable to rising interest rates and, to a lesser extent, widening spreads related to the Federal Reserve's plans for quantitative tightening and benchmark interest rate increases. Continuing supply-chain disruptions, inflationary indicators and geopolitical events have also led to market uncertainty, producing some yield curve dislocations.
U.S. Government Agency and Government Sponsored Enterprise Securities
At March 31, 2022, five U.S. treasury, fifty-eight U.S. Government agency and sponsored enterprise residential MBS, twenty-four U.S. Government agency and sponsored enterprise commercial MBS, and ten 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 entire 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 March 31, 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 March 31, 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 March 31, 2022, ninety-nine 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 March 31, 2022 analysis projected weighted average collateral losses for impaired securities in this category of 2% compared to weighted average credit support of 17%. As of March 31, 2022, 95% of impaired securities in this category, based on carrying value, were externally rated AAA, 1% were rated AA and 4% were rated A.
Private label commercial MBS
At March 31, 2022, eighty-three 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, special servicing trends, delinquency and other economic data that could be indicative of stress in the sector. Our March 31, 2022 analysis projected weighted average collateral losses for impaired securities in this category of 6% compared to weighted average credit support of 42%. As of March 31, 2022, 88% of impaired securities in this category, based on carrying value, were externally rated AAA, 9% were rated AA and 3% were rated A.
Single family real estate-backed securities
At March 31, 2022, sixteen 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 prices appreciation, forbearance, delinquency and prepay trends as well as other economic data that could be indicative of stress in the sector. Our March 31, 2022 analysis projected weighted average collateral losses for this category of 5% compared to weighted average credit support of 48%. As of March 31, 2022, 76% of impaired securities in this category, based on carrying value, were externally rated AAA, 16% were rated AA and one security was not rated.
Collateralized loan obligations
At March 31, 2022, twenty-five 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 March 31, 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 March 31, 2022, 81% of the impaired securities in this category, based on carrying value, were externally rated AAA, 15% were rated AA and 4% were rated A.
Non-mortgage asset-backed securities
At March 31, 2022, six 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 March 31, 2022 analysis projected weighted average collateral losses for impaired securities in this category of 3% compared to weighted average credit support of 21%. As of March 31, 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 Obligations
At March 31, 2022, four 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 March 31, 2022, all of the impaired securities in this category, based on carrying value, were externally rated AAA.

Credit quality information
The credit quality of the loan portfolio has been and may continue to be impacted by the COVID-19 crisis, its impact on the economy broadly and more specifically on the Company's individual borrowers. While economic conditions continue to improve, some level of uncertainty continues to exist about the full extent of this impact and the trajectory of recovery. The ultimate impact may not be fully reflected in some of the credit quality indicators disclosed below.

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 first 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 the multi-family, non-owner occupied commercial real estate and owner-occupied commercial real estate loan classes generally consists of commercial real estate. 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 three months ended March 31, 2022.

TDRs during the three months ended March 31, 2022 and 2021 generally included interest rate reductions and extensions of maturity. Included in TDRs are residential loans to borrowers who have not reaffirmed their debt discharged in Chapter 7 bankruptcy. The total amount of such loans is not material.
Note 5    Income Taxes
The Company’s effective income tax rate was 24.4% and 24.7% for the three months ended March 31, 2022 and 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 and caps 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 months ended March 31, 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 March 31, 2022 and December 31, 2021.

Some of the Company’s ISDA master agreements with financial institution counterparties contain provisions that permit either counterparty to terminate the agreements and require settlement in the event that regulatory capital ratios fall below certain designated thresholds, upon the initiation of other defined regulatory actions or upon suspension or withdrawal of the Bank’s credit rating. Currently, there are no circumstances that would trigger these provisions of the agreements.

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.
Servicing rights—Commercial servicing rights are valued using a discounted cash flow methodology incorporating contractually specified servicing fees and market based assumptions about prepayments, discount rates, default rates and costs of servicing. Prepayment and default assumptions are based on historical industry data for loans with similar characteristics. Assumptions about costs of servicing are based on market convention. Discount rates are based on rates of return implied by observed trades of underlying loans in the secondary market. As all significant inputs to the valuation process are observable, these instruments are classified within level 2 of the fair value hierarchy.
Derivative financial instruments—Fair values of interest rate swaps and caps 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 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 March 31, 2022 were as follows (in thousands):
Commitments to fund loans$631,426 
Unfunded commitments under lines of credit 4,329,074 
Commercial and standby letters of credit 108,781 
$5,069,281 
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 three months ended March 31, 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 March 31, 2022 was $67.2 million, or $0.79 per diluted share, compared to $98.8 million, or $1.06 per diluted share, for the three months ended March 31, 2021 and $125.3 million or $1.41 per diluted share for the immediately preceding three months ended December 31, 2021. As previously reported, earnings for the quarter ended December 31, 2021 were impacted by discrete income tax benefits of $69.1 million and a $44.8 million pre-tax loss on discontinuance of hedges. Earnings for the quarter ended March 31, 2021 were favorably impacted by a $28.0 million recovery of the provision for credit losses. For the three months ended March 31, 2022, the annualized return on average stockholders' equity was 9.0% and the annualized return on average assets was 0.76%.
The net interest margin, calculated on a tax-equivalent basis, expanded to 2.50% for the three months ended March 31, 2022 from 2.44% for the immediately preceding three months and 2.39% for the three months ended March 31, 2021. Net interest income increased by $2.6 million compared to the immediately preceding three months ended December 31, 2021 and by $12.4 million compared to the three months ended March 31, 2021.
The average cost of total deposits was 0.17% for the three months ended March 31, 2022 compared to 0.19% for the immediately preceding three months ended December 31, 2021 and 0.33% for the three months ended March 31, 2021. On a spot basis, the APY on total deposits was 0.16% at both March 31, 2022 and December 31, 2021, compared to 0.27% at March 31, 2021.
Non-interest bearing demand deposits grew by $688 million during the three months ended March 31, 2022. At March 31, 2022, non-interest bearing demand deposits represented 34% of total deposits, compared to 30% of total deposits at December 31, 2021. Total deposits declined by $897 million during the three months ended March 31, 2022, with declines in interest bearing demand, savings and money market and time deposits. The majority of deposit
31





outflows were accounts that, based on prior experience, we would expect to be price sensitive in a rising rate environment.
Total loans, excluding the runoff of PPP loans, declined by $227 million for the three months ended March 31, 2022, while average loans, excluding PPP loans, increased by $586 million.
The ratio of non-performing loans to total loans declined to 0.65% at March 31, 2022 from 0.87% at December 31, 2021. The guaranteed portion of SBA loans on non-accrual status represented 0.18% of total loans at March 31, 2022. Criticized and classified loans continued to decline. During the three months ended March 31, 2022, total criticized and classified loans declined by $280 million.
For the three months ended March 31, 2022, the Company recorded a provision of credit losses of $7.8 million compared to a provision for credit losses of $0.2 million, for the immediately preceding three months ended December 31, 2021 and a recovery of credit losses of $(28.0) million for the three months ended March 31, 2021.
Results for the three months ended March 31, 2022 were impacted by declines in the fair value of investment securities. Accumulated other comprehensive income declined by $142 million for the three months ended March 31, 2022, primarily due to an increase in unrealized losses on investment securities available for sale. Non-interest income was impacted by a $10.5 million decline in the fair value of certain preferred stock investments. These declines in the fair value of securities resulted primarily from widening spreads and rising interest rates related to the Federal Reserve's plans for quantitative tightening and benchmark interest rate increases, as well as inflationary concerns. None of the unrealized losses were attributable to credit loss impairments; the Company expects to recover the amortized cost basis of its available for sale securities.
Book value per common share and tangible book value per common were $34.04 and $33.12, respectively, at March 31, 2022.
In February 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 March 31, 2022, the Company repurchased approximately 1.9 million shares of its common stock for an aggregate purchase price of $82 million, at a weighted average price of $42.50 per share.
The Company announced an increase of $0.02 in its cash dividend for the three months ended March 31, 2022 to $0.25 per common share, reflecting a 9% increase from the previous quarterly dividend of $0.23 per common share.
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):

(1)On a tax-equivalent basis where applicable. The tax-equivalent adjustment for tax-exempt loans was $3.0 million, $3.1 million and $3.5 million for the three months ended March 31, 2022, December 31, 2021 and March 31, 2021, respectively. The tax-equivalent adjustment for tax-exempt investment securities was $0.7 million for all periods presented.

Three months ended March 31, 2022 compared to the immediately preceding three months ended December 31, 2021
Net interest income, calculated on a tax-equivalent basis, was $212.3 million for the three months ended March 31, 2022, compared to $209.8 million for the three months ended December 31, 2021, an increase of $2.5 million. The increase in net interest income was comprised of decreases in tax-equivalent interest income and interest expense of $2.0 million and $4.5 million, respectively, for the three months ended March 31, 2022, compared to the three months ended December 31, 2021. The decrease in interest income reflected a lower yield on average loans and lower day count, partially offset by a higher average balance of loans and higher yield on investment securities. The decrease in interest expense reflected a lower cost of both interest bearing deposits and FHLB advances and lower day count, partially offset by a higher average balance of interest-bearing liabilities, particularly FHLB advances.

The net interest margin, calculated on a tax-equivalent basis, was 2.50% for the three months ended March 31, 2022, compared to 2.44% for the three months ended December 31, 2021. Offsetting factors impacting the net interest margin for the three months ended March 31, 2022 compared to the immediately preceding three months ended December 31, 2021 included:
The tax-equivalent yield on investment securities increased to 1.73%, for the three months ended March 31, 2022 from 1.54% for the three months ended December 31, 2021. This increase resulted from the impact of purchases of higher-yielding securities and slower prepayment speeds on securities purchased at a premium.
The tax-equivalent yield on loans decreased to 3.36% for the three months ended March 31, 2022, from 3.50% for the three months ended December 31, 2021. Factors contributing to this decrease included runoff of loans originated in a comparatively higher rate environment, slower prepayment speeds on PCD residential loans, the effect of the sale of a pool of higher yielding residential loans during the fourth quarter of 2021, lower prepayment penalties and partially offsetting higher PPP fee recognition.
The average rate paid on FHLB advances decreased to 1.11% for the three months ended March 31, 2022 from 1.86% for the three months ended December 31, 2021. This decrease resulted from the maturity of higher rate advances, including the termination of certain cash flow hedges during the three months ended December 31, 2021, and the addition of new advances at comparatively lower prevailing rates.
The average rate paid on interest bearing deposits decreased to 0.24% for the three months ended March 31, 2022, from 0.27% for the three months ended December 31, 2021. Callable and other brokered CDs and cash flow hedges entered into in anticipation of rising rates impacted the cost of deposits for the quarter; the average rate paid on interest bearing deposits excluding these instruments was 0.21% for the quarter ended March 31, 2022. The increase in the average cost of time deposits for the quarter ended March 31, 2022 compared to the quarter ended December 31, 2021 was attributable to these products. The average cost of time deposits other than these products was 0.22% for the quarter ended March 31, 2022.
Three months ended March 31, 2022 compared to the three months ended March 31, 2021
Net interest income, calculated on a tax-equivalent basis, was $212.3 million for the three months ended March 31, 2022, compared to $200.4 million for the three months ended March 31, 2021, an increase of $11.9 million. The increase in net interest income was comprised of decreases in tax-equivalent interest income and interest expense of $10.0 million and $21.9 million, respectively, for the three months ended March 31, 2022, compared to the three months ended March 31, 2021. The decrease in interest income related to lower interest income on loans, resulting primarily from the turnover of the loan portfolio at lower prevailing rates, partially offset by an increase in interest income on investment securities related to an increase in the average balance. The decline in interest expense reflected lower interest expense on both deposits and FHLB advances. The decrease in interest expense on deposits reflected both a decline in the average balance of interest-bearing deposits and a decline in the cost of those deposits resulting from the impact of our strategy focused on lowering the cost of deposits and improving the deposit mix as well as term deposits repricing at lower prevailing rates. The decline in interest expense on FHLB advances reflected a lower average balance, the maturities of higher rate FHLB advances and the termination of certain cash flow hedges in the fourth quarter of 2021.
The net interest margin, calculated on a tax-equivalent basis, was 2.50% for the three months ended March 31, 2022, compared to 2.39% for the three months ended March 31, 2021. The reduction in cost of interest bearing liabilities outpaced the decline in the yield on interest earning assets.
The tax-equivalent yield on loans decreased to 3.36% for the three months ended March 31, 2022, from 3.58% for the three months ended March 31, 2021. This decrease resulted primarily from the runoff of loans originated in a comparatively higher rate environment.
The average rate paid on interest bearing deposits decreased to 0.24% for the three months ended March 31, 2022, from 0.45% for the three months ended March 31, 2021. This decrease resulted from declines in prevailing interest rates and continues execution of initiatives taken to lower rates on deposits, including the re-pricing of term deposits.
The average rate paid on FHLB advances decreased to 1.11% for the three months ended March 31, 2022, from 2.32% for the three months ended March 31, 2021. The decrease resulted from the maturity of higher rate advances and the termination of certain cash flow hedges in the fourth quarter of 2021.
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
34





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.
The following table presents the components of the provision for (recovery of) credit losses for the periods indicated (in thousands):
Three Months Ended March 31,
20222021
Amount related to funded portion of loans$7,446 $(26,306)
Amount related to off-balance sheet credit exposures384 (1,048)
Amount related to accrued interest receivable — (271)
Amount related to AFS debt securities— (364)
Total provision for (recovery of) credit losses$7,830 $(27,989)
The provision for credit losses for the three months ended March 31, 2022 was impacted by an increase in qualitative loss factors related to economic uncertainty. Those qualitative considerations included but were not necessarily limited to the Federal Reserve's plans for quantitative tightening and increasing its benchmark rate and geopolitical uncertainty, some of which have emerged or evolved subsequent to publishing of the economic scenarios used in developing the quantitative estimate of the ACL. The recovery of credit losses for the three months ended March 31, 2021 was largely driven by improvements in forecasted economic conditions.
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 the economic outlook and by the evolving impact of the COVID-19 pandemic, geopolitical events, and their impact on individual borrowers in the portfolio.
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 months ended March 31, 2022.
Non-Interest Income

Lease financing13,415 12,488 
Other non-interest income3,618 8,789 
$14,301 $30,296 
The increase in deposit service charges for the three months ended March 31, 2022 resulted primarily from higher treasury management fee income, related to growth in commercial non-interest bearing DDA relationships as well as enhancements to the product suite and pricing structure.
The unrealized loss on marketable equity securities for the three months ended March 31, 2022 was attributable to the decline in the fair value of certain preferred stock investments resulting from rising market interest rates.
The most significant factors leading to the decrease in other non-interest income for the three months ended March 31, 2022 compared to the three months ended March 31, 2021 were declines in income related to certain investments in bank-owned life insurance and revenue related to our customer derivative program.

Employee compensation and benefits
Employee compensation and benefits increased by $7.8 million for the three months ended March 31, 2022 compared to the three months ended March 31, 2021. The increase was primarily due to increased headcount and employee compensation increases.
Deposit insurance expense
Deposit insurance expense decreased by $4.0 million for the three months ended March 31, 2022, compared to the three months ended March 31, 2021, primarily as a result of an improvement in the assessment rate.
Income Taxes
See Note 5 to the consolidated financial statements for information about income taxes.
Analysis of Financial Condition
Average interest-earning assets increased by $425 million to $34.1 billion for the three months ended March 31, 2022 from $33.7 billion for the three months ended March 31, 2021, primarily due to an increase in the average balance of investment securities. Average interest bearing liabilities declined by $912.9 million for the three months ended March 31, 2022 compared to the three months ended March 31, 2021, reflecting declines in both average interest-bearing deposits and average FHLB advances. Correspondingly, average non-interest bearing deposits increased by $1.6 billion to $9.0 billion for the three months ended March 31, 2022. These year-over-year trends in average balances were reflective of the operating environment as the U.S. economy began to emerge from the COVID-19 pandemic. Our ongoing strategy focused on improving the quality of our deposit base coupled with increased amounts of liquidity in the system led to growth in non-interest bearing demand deposits and corresponding declines in interest bearing sources of funds. Headwinds to commercial loan growth including muted demand, our risk appetite given continued uncertainty about the ultimate impact of the pandemic, prepayments and supply chain constraints led to deployment of liquidity into the securities portfolio.
In analyzing changes in the balance sheet for the quarter ended March 31, 2022, cash and investment securities grew by $891 million, with securities growing by $508 million, at March 31, 2022 compared to December 31, 2021, while total loans declined by $395 million over the same period. Total deposits decreased by $897 million. This activity was offset by an increase of $1.5 billion in FHLB advances. Growth in the investment portfolio, which we did not initially anticipate would occur during the first quarter, reflected opportunistic purchases of securities at attractive spreads toward the end of the quarter. The most significant contributor to the decline in total loans was a decrease of $391 million in mortgage warehouse loans as refinancing activity has slowed in response to rising interest rates. While total deposits declined during the first quarter of 2022, non-interest bearing demand deposits grew by $688 million. The decrease in total deposits reflected declines in interest bearing demand, savings and money market, and time deposits. The majority of deposit outflows were accounts that, based on prior experience, we would expect to be price sensitive in a rising rate environment and was consistent with our overall deposit strategy.

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 March 31, 2022 was 4.4 years and the effective duration of the portfolio was 1.7 years.

The investment securities available for sale portfolio was in a net unrealized loss position of $235.3 million at March 31, 2022. Net unrealized losses at March 31, 2022 included $17.5 million of gross unrealized gains and $252.8 million of gross unrealized losses. Investment securities available for sale in unrealized loss positions at March 31, 2022 had an aggregate fair value of $8.4 billion. The unrealized losses resulted primarily from rising interest rates and widening spreads related to the Federal Reserve's plans for quantitative tightening and benchmark interest rate increases. None of the unrealized losses were attributable to credit loss impairments. The ratings distribution of our AFS securities portfolio at March 31, 2022 is depicted in the chart below:
bku-20220331_g1.jpg
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 March 31, 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.

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 three months ended March 31, 2022, total loans declined by $395 million, while total loans, excluding PPP loans, declined by $227 million.
Residential and other consumer loans grew by $244 million during the quarter ended March 31, 2022. Commercial and industrial loans, including owner-occupied commercial real estate, grew by $122 million for the quarter. Most of the remaining commercial portfolio segments showed declines for the quarter. MWL utilization declined to 39% at March 31, 2022 compared to 56% at December 31, 2021 as rising rates have led to lower refinancing activity and we believe this segment is evidencing a return to historically normal seasonal utilization patterns. PPP loans declined by $168 million during the quarter ended March 31, 2022, resulting from full or partial forgiveness from the SBA.

Residential mortgages and other consumer loans
The following table shows the composition of residential and other consumer loans at the dates indicated (in thousands):
March 31, 2022December 31, 2021
1-4 single family residential $6,668,116 $6,338,225

Other consumer loans 6,244 6,934 
$8,612,839 $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 March 31, 2022, $927 million or 14% 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. The balance of buyout loans totaled $1.9 billion at March 31, 2022. The Company is not the servicer of these loans.

Included in the table above are approximately $119 million of mixed-use properties in New York, consisting of $55 million categorized as multi-family, $46 million categorized as retail and $18 million categorized as office. The New York multi-family portfolio included $437 million of loans collateralized by properties with some or all of the units subject to rent regulation at March 31, 2022, substantially all of which were stabilized properties.
Commercial and industrial loans are typically made to small, middle market and larger corporate businesses and not-for-profit entities and include equipment loans, secured and unsecured working capital facilities, formula-based loans, trade finance, SBA product offerings, business acquisition finance credit facilities and commercial credit cards. These loans may be structured as term loans, typically with maturities of five to seven years, or revolving lines of credit which may have multi-year maturities. The Bank also provides financing to state and local governmental entities generally within our geographic markets. Commercial loans included loans meeting the regulatory definition of shared national credits totaling $3.3 billion at March 31, 2022, the majority of which were relationship based loans to borrowers in Florida and New York. The Bank makes loans secured by owner-occupied commercial real estate that typically have risk profiles more closely aligned with that of commercial and industrial loans than with other types of commercial real estate 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
45





or improbable, but because of certain reasonably specific pending factors have not been charged off, are assigned an internal risk rating of doubtful.

Our internal risk ratings at March 31, 2022 continued to be influenced by the impact of the COVID-19 pandemic and the measures and restrictions employed to contain the spread of the virus on the economy, our borrowers and the sectors in which they operate, 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 three months ended March 31, 2022, levels of criticized and classified loans declined in response to the trajectory of the economic recovery. If the economic recovery and its impact on individual borrowers evolve in line with our current expectations and economic forecast, we would expect to see the level of criticized and classified loans continue to decline over the course of 2022. However, uncertainty remains around the future trajectory of the economy due to a number of factors. In light of that uncertainty, it is possible that criticized and classified loan levels may not decline or that they may increase.

Payment Deferrals and Modifications
At March 31, 2022, commercial loans under CARES Act modification totaled $117 million. All of the commercial loans that have rolled off of modification have paid off or resumed regular payments. CARES Act modifications most commonly have taken the form of 9 to 12 month interest only periods. The majority of loan modifications that took place after the onset of the COVID-19 pandemic and through December 31, 2021 were not categorized as TDRs, in accordance with interagency and authoritative guidance and the provisions of the CARES Act, which expired effective January 1, 2022.
Operating Lease Equipment, net
Three operating leases with a carrying value of assets under lease totaling $18 million, all of which were exposures to the energy industry, were internally risk rated substandard at March 31, 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 during the three months ended March 31, 2022 or March 31, 2021.
The primary risks inherent in the equipment leasing business are asset risk resulting from ownership of the equipment on lease and credit risk. Asset risk arises from fluctuations in supply and demand for the underlying leased equipment. The equipment is leased to commercial end users with original lease terms generally ranging from three to ten years. We are exposed to the risk that, at the end of the lease term, the value of the asset will be lower than expected, potentially resulting in reduced future lease income over the remaining life of the asset or a lower sale value. Asset risk may also lead to changes in depreciation as a result of changes in the residual values of the leased assets or impairment of asset carrying values.
47





Asset risk is evaluated and managed by a dedicated internal staff of asset managers, managed by seasoned equipment finance professionals with a broad depth and breadth of experience in the leasing business. Additionally, we have partnered with an industry leading, experienced service provider who provides fleet management and servicing relating to the railcar fleet, including lease administration and reporting, a Regulation Y compliant full service maintenance program and railcar re-marketing. Risk is managed by setting appropriate residual values at inception and systematic reviews of residual values based on independent appraisals, performed at least annually. Additionally, our internal management team and our external service provider closely follow the rail markets, monitoring traffic flows, supply and demand trends and the impact of new technologies and regulatory requirements. Demand for railcars is sensitive to shifts in general and industry specific economic and market trends and shifts in trade flows from specific events such as natural or man-made disasters. We seek to mitigate these risks by leasing to a stable end user base, by maintaining a relatively young and diversified fleet of assets that are expected to maintain stronger and more stable utilization rates despite impacts from unexpected events or cyclical trends and by staggering lease maturities. We regularly monitor the impact of oil prices on the estimated residual value of rail cars being used in the petroleum/natural gas extraction sector.
Credit risk in the leased equipment portfolio results from the potential default of lessees, possibly driven by obligor specific or industry-wide conditions, and is economically less significant than asset risk, because in the operating lease business, there is no extension of credit to the obligor. Instead, the lessor deploys a portion of the useful life of the asset. Credit losses, if any, will manifest through reduced rental income due to missed payments, time off lease, or lower rental payments due either to a restructuring or re-leasing of the asset to another obligor. Credit risk in the operating lease portfolio is managed and monitored using credit administration infrastructure, processes and procedures similar to those used to manage and monitor credit risk in the commercial loan portfolio. We also mitigate credit risk in this portfolio by leasing to high credit quality obligors.
Bridge had exposure to the energy industry of $272 million at March 31, 2022. The majority of the energy exposure was in the operating lease equipment portfolio where energy exposure totaled $235 million. The remaining energy exposure, totaling approximately $37 million was comprised of loans and direct or sales type finance leases.
Residential and Other Consumer 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 and consumer 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 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 March 31, 2022:
bku-20220331_g5.jpg
FICO scores are generally updated at least annually, and were most recently updated in the first quarter of 2022. LTVs are typically based on valuation at origination since we do not routinely update residential appraisals.
At March 31, 2022, the majority of the 1-4 single family residential loan portfolio, excluding government insured residential loans, was owner-occupied, with 81% primary residence, 5% second homes and 14% investment properties.
48





1-4 single family residential loans excluding government insured residential loans past due more than 30 days totaled $70 million and $76 million at March 31, 2022 and December 31, 2021, respectively. The amount of these loans 90 days or more past due was $15 million and $17 million at March 31, 2022 and December 31, 2021, respectively. At March 31, 2022, $32 million or less than 1% of 1-4 single family residential loans, excluding government insured residential loans, remained under short-term deferral or had been modified due to the COVID-19 pandemic.
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.

Contractually delinquent government insured residential loans are typically GNMA early buyout loans and are excluded from non-performing loans as defined in the table above due to their government guarantee. The carrying value of such loans contractually delinquent by 90 days or more was $704 million and $730 million at March 31, 2022 and December 31, 2021, respectively.
See "Results of Operations - Provision for Credit Losses" above and “Analysis of the Allowance for Credit Losses” below for further discussion of trends in the Provision for Credit Losses and the ACL.
The following chart presents trends in non-performing loans and non-performing assets. Levels of non-performing loans and non-performing assets have returned to below pre-pandemic levels.

The following chart presents trends in non-performing loans by portfolio sub-segment (in millions):
bku-20220331_g7.jpg
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. Residential loans that have rolled off of short-term deferral and have not caught up on their deferred payments may also be placed on non-accrual; these loans are typically pending modification. 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.

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 or CARES Act modifications 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 complies with interagency guidance and the CARES Act under which we have 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. See the sections entitled "Asset Quality - Commercial Loans - Payment Deferrals" and "Asset Quality - Residential and Other Consumer Loans" for further details about COVID-19 related payment deferrals and modifications.
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. Economic uncertainty remains around the impact the continually evolving COVID-19 situation, emerging inflationary concerns and current geopolitical events will have on the economy broadly, and on our borrowers specifically. Given this 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, in either direction. 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.
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 both March 31, 2022 and December 31, 2021, a baseline scenario provided by an external party was used in estimating the ACL.
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 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 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.
50





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.
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 March 31, 2022 are depicted in the chart below (in millions):
bku-20220331_g8.jpg
Changes in the ACL during the three months ended March 31, 2022
The ACL for the CRE portfolio sub-segment, including multi-family, non-owner occupied CRE and construction and land, increased by $4.7 million during the three months ended March 31, 2022, from 0.51% to 0.61% of loans. The increase in the ACL for CRE was driven mainly by the increase in qualitative loss factors related to economic uncertainty, partially offset by net charge-offs.
The ACL for the commercial and industrial sub-segment, including owner-occupied commercial real estate, decreased by $2.2 million during the three months ended March 31, 2022. Significant factors contributing to the decrease included (i) the decline in criticized and classified loans; (ii) a decrease related to the impact of the economic forecast; and (iii) a decrease in specific reserves; partially offset by (iv) a decrease in estimated prepayment speeds; and (v) the increase in qualitative loss factors related to economic uncertainty. The ACL coverage ratio for these loans increased from 0.84% to 0.86% during the three months ended March 31, 2021 despite the decline in the ACL. This was driven by the decline in the amortized cost basis of MWL and PPP loans, which carry nominal or no reserves, during the quarter.
The ACL for the BFG franchise finance portfolio segment decreased by $2.3 million during the three months ended March 31, 2022, from 4.90% to 4.71% of loans. This decrease is primarily attributed to reduced levels of criticized and classified loans and improvements in the economic forecast.
The ACL for the BFG equipment finance portfolio segment decreased by $0.9 million during the three months ended March 31, 2022, from 1.00% to 0.78% of loans, resulting primarily from risk rating upgrades, and to a lesser extent, faster prepayment speed assumptions partially offset by an increase in qualitative factors related to economic uncertainty.
The estimate of the ACL at March 31, 2022 was informed by economic scenarios published in March 2022, developments emerging after the scenarios were published, 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 ACL as of March 31, 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 ACL at March 31, 2022 included:
53





Labor market assumptions, which reflected national unemployment at 3.7% for the second quarter of 2022, steadily declining to normalized levels of full employment of 3.5% through the end of 2022 and 3.4% throughout 2023;
Annualized growth in GDP at 4.8% for the second quarter of 2022, normalizing to an average of 3.4% and 3.2% for 2022 and 2023;
VIX trending at stabilized levels through the forecast horizon; and
S&P 500 averaging near 4,200 through the reasonable and supportable forecast period.
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.
For additional information about the ACL, see Note 4 to the consolidated financial statements.

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 been and continue to be 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 three months ended March 31, 2022 and 2021 net cash provided by operating activities was $457 million and $386 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 March 31, 2022, BankUnited was in compliance with the limits prescribed by the ALM policy.
55


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 March 31, 2022, BankUnited’s available liquidity/volatile liabilities ratio was 309% and the liquidity stress test ratio was 188%. 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 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.
We expect that our liquidity needs and cash requirements will continue to be satisfied over the next twelve months through the sources of funds described above.
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 March 31, 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.

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
56


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. 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 March 31, 2022 and December 31, 2021, as well as a minus 100 basis points scenario at March 31, 2022. At March 31, 2022, the most likely rate scenario incorporated a bear flattening yield curve and floored all indices at 0%. We did not apply the falling rate scenario at December 31, 2021 due to the low prevailing interest rate environment at that time.

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 swaps and caps 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 March 31, 2022, outstanding interest rate swaps and caps designated as cash flow hedges had an aggregate notional amount of $1.2 billion and outstanding interest rate swaps designated as fair value hedges had an aggregate notional amount of $100 million.
57


Interest rate swaps and caps not designated as hedges had an aggregate notional amount of $3.4 billion at March 31, 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 March 31, 2022 (in thousands):

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 the first quarter of 2022 were characterized broadly by economic recovery as the U.S. economy emerged from the COVID-19 pandemic, evidenced by improving economic indicators such as GDP growth, unemployment and property valuations. The actual and expected impact of the pandemic on our financial condition and results of operations are expected to continue to lessen, although we are still closely monitoring emerging developments. Levels of criticized and classified assets remain elevated at March 31, 2022, when compared to pre-pandemic levels although they continue to trend downward. The ACL at March 31, 2022 still included certain qualitative loss factors related to the COVID-19 pandemic, and we continue to monitor the potential impact on expected credit losses of developments related to the pandemic. The composition of the balance sheet at March 31, 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
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):

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 March 31, 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 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.
