NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - UNAUDITED

March 31, 2021

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 69 banking centers located in 14 Florida counties and 4 banking centers located in the New York metropolitan area at March 31, 2021. 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, 2020 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, 2021 are not necessarily indicative of the results that may be expected in future periods.

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, 2021

ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. This ASU simplifies the accounting for income taxes by removing certain exceptions stipulated in ASC 740 and making some other targeted changes to the accounting for income taxes. The Company adopted this ASU on January 1, 2021 with no material impact on the Company’s consolidated financial position, results of operations, and cash flows.

ASU No. 2021-01, Reference Rate Reform (Topic 848). This ASU clarifies that certain optional expedients and exceptions provided for in ASU No. 2020-04 for applying GAAP to contract modifications and hedging relationships apply to derivatives that are affected by the discounting transition. The amendments in this ASU are elective and apply to all entities that have derivative instruments that use an interest rate for margining, discounting, or contract price alignment that is modified as a result of reference rate reform. The Company elected to adopt this ASU on a retrospective basis. The impact of adoption of this ASU on the Company's consolidated financial position, results of operations, and cash flows was not material.

Accounting Pronouncements Not Yet Adopted

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. This ASU is effective for the Company for interim and annual periods in fiscal years beginning after December 15, 2021. The Company has not finalized its evaluation of the impact of adoption on its consolidated financial position, results of operations, and cash flows, but the impact is not currently expected to be material.

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, 2021 and 2020. At March 31, 2021 the Company did not have an intent to sell securities that were in significant 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, 2021, 165 securities available for sale were in unrealized loss positions. The unrealized losses are primarily attributable to changes in interest rates and, in some cases, volatility in the financial markets since their purchase. The amount of impairment related to 51 of these securities was considered insignificant both individually and in the aggregate, totaling approximately $0.5 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, 2021 is further discussed below.

U.S. Government Agency and Government Sponsored Enterprise Securities

At March 31, 2021, four U.S. treasury, twenty-nine U.S. Government agency and sponsored enterprise residential MBS, eleven U.S. Government agency and sponsored enterprise commercial MBS and eleven 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, 2021. 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 severe than our reasonable and supportable economic forecast at March 31, 2021, 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.

March 31, 2021

Private label residential MBS and CMOs

At March 31, 2021, eight 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 which would indicate further stress in the sector. Our March 31, 2021 analysis projected weighted average collateral losses for impaired securities in this category of 2% compared to weighted average credit support of 13%. As of March 31, 2021, all of the impaired securities in this category were externally rated AAA.

Private label commercial MBS

At March 31, 2021, twenty-seven 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 which would indicate further stress in the sector. Unrealized losses in this sector were primarily attributable to changes in benchmark interest rates.

Our March 31, 2021 analysis projected weighted average collateral losses for impaired securities in this category of 11% compared to weighted average credit support of 38%. As of March 31, 2021, 82% of impaired securities in this category, based on carrying value, were externally rated AAA, 11% were rated AA and 7% were rated A.

Single family rental real estate-backed securities

At March 31, 2021, three 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 which would indicate further stress in the sector. Our March 31, 2021 analysis projected weighted average collateral losses for this category of 19% compared to weighted average credit support of 45%. As of March 31, 2021, all of the impaired securities in this category were externally rated AAA.

Collateralized loan obligations

At March 31, 2021, twenty-one collateralized loan obligations were in unrealized loss positions primarily due to widening spreads since the date of purchase. Unrealized losses in this portfolio sector are now lower than their pre-COVID levels in the aggregate. 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, 2021 analysis projected weighted average collateral losses for impaired securities in this category of 22% compared to weighted average credit support of 43%. As of March 31, 2021, 79% of the impaired securities in this category, based on carrying value, were externally rated AAA, 16% were rated AA and 5% were rated A.

Premiums, discounts and deferred fees and costs, excluding the non-credit related discount on PCD loans, totaled $35 million and $39 million at March 31, 2021 and December 31, 2020, respectively. The amortized cost basis of residential PCD loans was $110 million and the related amount of non-credit discount was $106 million at March 31, 2021. The ACL related to PCD residential loans was $2.2 million and $2.8 million at March 31, 2021 and December 31, 2020, respectively.

Included in the table above are direct or sales type finance leases totaling $665 million and $670 million at March 31, 2021 and December 31, 2020, respectively. The amount of income recognized from direct or sales type finance leases for the three months ended March 31, 2021 and 2020 totaled $5.4 million and $5.5 million, respectively and is recorded as interest income on loans in the consolidated statements of income.

During the three months ended March 31, 2021 and 2020, the Company purchased 1-4 single family residential loans totaling $963 million and $503 million, respectively. Purchases for the three months ended March 31, 2021 and 2020 included $578 million, and $286 million, respectively, of government insured residential loans.

At March 31, 2021 and December 31, 2020, the Company had pledged loans with a carrying value of approximately $9.4 billion and $9.6 billion, respectively, as security for FHLB advances and Federal Reserve discount window capacity.

The decrease in the ACL from December 31, 2020 to March 31, 2021 related primarily to the recovery of credit losses recorded during the three months ended March 31, 2021. The recovery of provision was driven largely by an improving economic forecast. The increase in the ACL from January 1, 2020, the date of initial adoption of ASU 2016-13, to March 31, 2020 was reflective of the impact of the COVID-19 pandemic on current economic conditions, the economic forecast and on individual borrowers and portfolio sub-segments.

Credit quality information

The credit quality of the loan portfolio has been and may continue to be impacted by the continuing COVID-19 crisis, its impact on the economy broadly and more specifically on the Company's individual borrowers. 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. Delinquency statistics may not be fully reflective of the impact of the COVID-19 crisis due to deferral and modification programs offered to affected borrowers.

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 2021. 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

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. Since the onset of the COVID-19 pandemic, risk ratings have been re-evaluated for a substantial portion of the commercial portfolio, with a focus on portfolio segments we identified for enhanced monitoring and loans that have been modified or for which we granted temporary payment deferrals. 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, 2021.

Foreclosure of residential real estate

The recorded investment in residential loans in the process of foreclosure was $205 million, of which $195 million was government insured, at March 31, 2021 and $217 million, of which $209 million was government insured, at December 31, 2020. The carrying amount of foreclosed residential real estate included in other assets in the accompanying consolidated balance sheet was insignificant at March 31, 2021 and December 31, 2020. In response to the COVID-19 pandemic, new foreclosure actions on residential loans have been temporarily suspended.

Troubled debt restructurings

The following table summarizes loans that were modified in TDRs during the periods indicated, as well as loans modified during the twelve months preceding March 31, 2021 and 2020 that experienced payment defaults during those periods (dollars in thousands):

TDRs during the three months ended March 31, 2021 and 2020 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. The majority of loan modifications or deferrals that took place after the onset of the COVID-19 pandemic have not been categorized as TDRs, in accordance with interagency and authoritative guidance and the provisions of the CARES Act.

Note 5 Income Taxes

The Company’s effective income tax rate was 24.7% and 23.4% for the three months ended March 31, 2021 and 2020, respectively. The effective income tax rates differed from the statutory federal income tax rate of 21% for the three months ended March 31, 2021 and 2020 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 enters into LIBOR-based interest rate swaps and caps that are designated as cash flow hedges with the objective of limiting the variability of interest payment cash flows. The Company also enters into LIBOR-based interest rate swaps designated as fair value hedges designed to hedge changes in the fair value of outstanding fixed rate borrowings 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, 2021 and 2020, 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 approximately zero at both March 31, 2021 and December 31, 2020.

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.

The Company does not offset assets and liabilities under master netting agreements for financial reporting purposes. Information on interest rate swaps subject to these agreements is as follows at the dates indicated (in thousands):

The difference between the amounts reported for interest rate swaps subject to master netting agreements and the total fair value of interest rate contract derivative financial instruments reported in the consolidated balance sheets is related to interest rate derivative contracts not subject to master netting agreements.

At March 31, 2021, the Company had pledged net financial collateral of $33.3 million as collateral for interest rate swaps in a liability position that are not centrally cleared. The amount of collateral required to be posted varies based on the settlement value of outstanding swaps and in some cases may include initial margin requirements.

Canceled or forfeited	(3,308)	38.58
Unvested share awards outstanding, March 31, 2020	1,216,073	$	34.22

Unvested share awards are generally valued at the closing price of the Company's common stock on the date of grant. All shares granted prior to 2019 vest in equal annual installments over a period of three years from the date of grant. All shares granted in 2019 and later to Company employees vest in equal annual installments over a period of four years from the date of grant. Shares granted to the Company's Board of Directors vest over a period of one year.

The following table summarizes the closing price of the Company's stock on the date of grant for shares granted and the aggregate grant date fair value of shares vesting for the periods indicated (in thousands, except per share data):

The total unrecognized compensation cost of $37.4 million for all unvested share awards outstanding at March 31, 2021 will be recognized over a weighted average remaining period of 3.18 years.

Executive share-based awards

Certain of the Company's executives are eligible to receive annual awards of RSUs and PSUs (collectively, the "share units"). Annual awards of RSUs represent a fixed number of shares and generally vest on December 31st in equal tranches over three years for grants prior to 2019, and over four years for awards issued in 2019 and after. PSUs are initially granted based on a target value. The number of PSUs that ultimately vest at the end of the performance measurement period will be based on the achievement of performance criteria pre-established by the Compensation Committee of the Board of Directors. Upon vesting, the share units will be converted to common stock on a one-for-one basis, or may be settled in cash at the Company's option. The share units will accumulate dividends declared on the Company's common stock from the date of grant to be paid subsequent to vesting.

As a result of the majority of previous settlements being in cash, all RSUs and PSUs have been determined to be liability instruments and are remeasured at fair value each reporting period until the awards are settled. The RSUs are valued based on the closing price of the Company's common stock at the reporting date. The PSUs are valued based on the closing price of the Company's common stock at the reporting date net of a discount related to any applicable market conditions, considering the

The total liability for the share units was $5.6 million at March 31, 2021. The total unrecognized compensation cost of $14.8 million for these share units at March 31, 2021 will be recognized over a weighted average remaining period of 2.39 years.

Incentive awards

The Company's annual incentive compensation arrangements for employees other than those eligible for the executive share-based awards discussed above provide for settlement through a combination of cash payments and unvested share awards following the end of the annual performance period. The dollar value of share awards to be granted is based on the achievement of performance criteria established in the incentive arrangements. The number of shares of common stock to be awarded is variable based on the closing price of the Company's stock on the date of grant; therefore, these awards are initially classified as liability instruments, with compensation cost recognized from the beginning of the performance period. Awards related to performance periods prior to 2019 vest over three years and awards related to the 2019 and subsequent performance periods vest in equal installments over a period of four years from the date of grant. No common stock was awarded pursuant to these incentive arrangements for the 2020 performance period. These awards are included in the summary of activity related to unvested share awards above. The accrued liability and unrecognized compensation cost are based on management's current estimate of the likely outcome of the performance criteria established in the incentive arrangements and may differ from actual results.

Option Awards

A summary of activity related to stock option awards for the three months ended March 31, 2021 and 2020 follows:


	Number of Option Awards	Weighted Average Exercise Price
Option awards outstanding, December 31, 2020	1,569	$	15.94

Note 9 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 rental 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. The Company has also established a quarterly process whereby prices provided by its primary pricing service for a sample of securities are validated. 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. 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 LIBOR swap rates and LIBOR 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, OREO and other repossessed assets—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. These adjustments to appraised values may be subjective and involve significant management judgment. The fair value of repossessed assets or collateral consisting of other business assets may be based on third-party appraisals or internal analyses that use market approaches to valuation incorporating a combination of observable and unobservable inputs.

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

Loans held for sale—Loans not originated or otherwise acquired with the intent to sell are transferred into the held for sale classification at the lower of carrying amount or fair value, typically determined based on the estimated selling price of the loans. These fair value measurements are typically 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 have been recorded (in thousands):

Note 10 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.

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, 2021 were as follows (in thousands):


Commitments to fund loans	$	418,775

Unfunded commitments under lines of credit	4,013,395
Commercial and standby letters of credit	90,291
	$	4,522,461

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, 2021 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 2020 Annual Report on Form 10-K for the year ended December 31, 2020 (the "2020 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 the COVID-19 pandemic. 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 2020 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.

Impact of the COVID-19 Pandemic and Our Response

In March 2020, the World Health Organization declared COVID-19 a global pandemic. Governmental authorities implemented a number of measures attempting to contain the spread and impact of COVID-19 such as travel bans and restrictions, quarantines, shelter in place orders, and limitations on business activities. While many of these restrictions have been lifted or moderated and economic activity has started to resume, the pandemic and these precautionary measures have negatively impacted the global and domestic economies, including in the Company's primary market areas. Certain sectors to which the Company has credit exposure, such as travel and hospitality and retail have been particularly impacted. The response of the U.S. Government to the economic impact of the crisis was swift and broad-based. The government has taken a series of actions to support individuals, households and businesses that have been negatively impacted by the economic disruption caused by the pandemic including enactment and subsequent extension of the CARES Act. The Federal Reserve also enacted a suite of facilities using its emergency lending powers designed to support liquidity and the flow of credit. Banking regulators reduced reserve requirements and enacted rules designed to support financial institutions in their efforts to work with customers during this time. While development and deployment of vaccines and improvements in treatments for the virus are positive signs and economic indicators are showing improvement, uncertainty remains about the future trajectory of the virus and its ultimate impact on the economy and on our financial condition and results of operations.

A summary of the effects the COVID-19 pandemic has had on our Company is discussed in the "Impact of the COVID-19 Pandemic and Our Response" section in the MD&A of the Company's 2020 Annual report on Form 10-K. A discussion of how our Company continues to be and may be impacted in the future follows. These matters are discussed in further detail throughout this Form 10-Q.

Our results of operations and financial condition were impacted by the COVID-19 pandemic.

•The COVID-19 pandemic and its effect on the economy and our borrowers has impacted the provision for credit losses and the ACL. The provision for credit losses has been more volatile since the onset of the pandemic; deterioration in economic conditions led to a higher provision for credit losses during the year ended December 31, 2020, while improvement in economic conditions and our reasonable and supportable economic forecast contributed to a recovery of provision for credit losses of $(28.0) million for the quarter ended March 31, 2021. While key economic indicators and our economic forecast have improved and the rollout of vaccines has been gaining momentum, there continues to be significant uncertainty as to the ultimate impact of the COVID-19 crisis on future credit loss expense and future levels of the ACL. 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 COVID-19 on individual borrowers in the portfolio.

•Levels of criticized and classified assets and non-performing assets increased in 2020, largely as a result of the COVID-19 pandemic and its impact or potential impact on our borrowers and certain portfolio sub-segments. Additionally, a significant number of borrowers requested and were granted relief in the form of temporary payment deferrals or modifications. Risk ratings were re-evaluated for a substantial portion of the commercial portfolio during 2020, with a particular focus on portfolio segments we identified for enhanced monitoring and loans for which we granted temporary payment deferrals or modifications in light of the COVID-19 pandemic. We continue to closely monitor risk rating of the commercial portfolio. At March 31, 2021, total criticized and classified loans had declined by approximately $75 million to $2.6 billion from $2.7 billion at December 31, 2020, however, we did experience further migration from the special mention category to the substandard accruing category during the first quarter of 2021. Non-performing assets decreased to $236.4 million at March 31, 2021 from $247.6 million at December 31, 2020. If the economic recovery continues on the path of our current reasonable and supportable forecast, we would expect to see the impact of that recovery on the operations of borrowers, and would expect the level of criticized and classified assets to decline over the remainder of 2021. However, uncertainty remains about the trajectory of the COVID-19 virus and the economy, and the specific impact on our borrowers; therefore, the level of criticized and classified assets may not decline, and could in fact increase. Similarly, non-performing assets, charge-offs and delinquencies could increase from current levels, particularly as loans currently subject to temporary payment deferrals and modifications reach the end of those deferral or modification periods.

•The level of commercial loan origination activity, outside of our participation in the PPP, was lower in 2020 as a result of the pandemic, and commercial loan demand remained below pre-pandemic levels through the first quarter of 2021. Line utilization also remained below pre-pandemic levels.

The pandemic continues to impact our operations. Currently, the substantial majority of our non-branch employees are working remotely. We have not experienced any significant operational difficulties, technology failures or outages, or customer service disruptions as a result of the transition to a remote work environment. 90% of our branches remain open to serve customers via drive-through or lobby appointments, in some cases operating with reduced hours. We have focused on ensuring that our technology systems and internal controls continue to operate effectively in a remote work environment. We have put mechanisms in place to allow us to evaluate all significant modifications to processes and procedures to insure continued effectiveness of our control environment. We have not identified any instances in which our control environment has failed to operate effectively.

Customer demand for our products and services, particularly lending products, has been and may continue to be negatively affected by the impact of the pandemic on their businesses or by social distancing measures. Potential borrowers impacted by the pandemic may no longer meet our underwriting criteria. Loan production in many portfolio segments may continue to be muted, at least in the near term. While we currently expect loan production to increase by the second half of 2021, our ability to increase production will depend on the future trajectory of the pandemic and on the pace and timing of economic recovery.

In response to the pandemic, we prioritized risk management and implemented a number of measures to support our customers, employees and communities. Specifically, we have:

•Activated and continue to operate under our business continuity plan under the leadership of executive management.

•Enhanced liquidity monitoring and management protocols, although we have not experienced constraints on liquidity since the onset of the pandemic.

•Maintained a regular cadence of Board of Directors update calls.

•Enhanced the level and frequency of pro-active outreach to borrowers and our portfolio management activities.

•Segregated certain segments of the loan portfolio for enhanced monitoring.

•Enhanced our workout and recovery staffing and processes.

•Enhanced our stress testing framework. Results of internal stress testing indicate that we have sufficient capital to withstand an increase in credit losses materially beyond levels currently expected, and to withstand a severe downturn.

•Proactively reached out to our critical third party service providers and evaluated their ability to continue to provide support in the current environment. We have experienced no significant service disruptions.

•Expanded certain employee benefits and launched a number of programs to keep our employees healthy and engaged.

•Enhanced personal protective measures for employees working at our corporate locations and begun planning for the eventual return to office of a larger percentage of our workforce, when conditions permit.

•Supported our clients through participating in the Small Business Administration’s PPP, the Federal Reserve's MSLF, and granting payment deferrals, loan modifications and fee waivers on a case-by-case basis.

•Temporarily halted new residential foreclosure actions.

•Disbursed over 150 grants to nonprofit organizations across our footprint, including an end of year donation of $100,000 to local food banks.

•Continued helping to meet the various needs of our community partners through over 1,500 employee "virtual" volunteer hours during the pandemic.

We remain confident in our long-term underlying strength and stability, and our ability to navigate these challenging conditions.

Overview

The following discussion and analysis presents the more significant factors that affected our financial condition as of March 31, 2021 and results of operations for the three months then ended. Refer to Item 2 "Management’s Discussion and Analysis of Financial Condition and Results of Operations" included in our Quarterly Report on Form 10-Q filed with the SEC on May 8, 2020 for a more comprehensive discussion and analysis of the quarter ended March 31, 2020.

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 earning assets and deposits, particularly non-interest bearing 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, 2021 was $98.8 million, or $1.06 per diluted share, compared to a net loss of $(31.0) million, or $(0.33) per diluted share, for the three months ended March 31, 2020 and net income of $85.7 million or $0.89 per diluted share for the immediately preceding quarter ended December 31, 2020. For the three months ended March 31, 2021, the return on average stockholders' equity was 13.2% and the return on average assets was 1.14%.

•Net interest income increased by $2.9 million compared to the immediately preceding three months ended December 31, 2020 and by $15.7 million compared to the three months ended March 31, 2020. The net interest margin, calculated on a tax-equivalent basis, was 2.39% for the three months ended March 31, 2021 compared to 2.33% for the immediately preceding quarter and 2.35% for the three months ended March 31, 2020.

•The average cost of total deposits declined by 0.10% to 0.33% for the three months ended March 31, 2021 from 0.43% for the immediately preceding three months ended December 31, 2020, and 1.36% for the three months ended March 31, 2020. On a spot basis, the APY on total deposits declined to 0.27% at March 31, 2021 from 0.36% at December 31, 2020 and 1.35% at March 31, 2020.

•For the three months ended March 31, 2021, the Company recorded a recovery of the provision for credit losses of $(28.0) million compared to a recovery of $(1.6) million for the immediately preceding three months ended December 31, 2020 and a provision for credit losses of $125.4 million for the three months ended March 31, 2020.

•PPNR improved to $103.3 million for the three months ended March 31, 2021 from $85.0 million for the three months ended March 31, 2020. PPNR was $105.3 million for the three months ended December 31, 2020.

•Non-interest bearing demand deposits grew by $957 million during the three months ended March 31, 2021. Total deposits grew by $236 million as higher cost time deposits continued to runoff, declining by $1.0 billion for the three months ended March 31, 2021. Average non-interest bearing demand deposits grew by $338 million for the three months ended March 31, 2021 compared to the immediately preceding quarter and by $3.1 billion compared to the three months ended March 31, 2020. At March 31, 2021, non-interest bearing demand deposits represented 29% of total deposits, compared to 25% of total deposits at December 31, 2020.

•Total loans and operating lease equipment declined by $487 million for the three months ended March 31, 2021.

•Loans on deferral totaled $126 million or less than 1% of total loans at March 31, 2021. Loans modified under the CARES Act totaled $636 million at March 31, 2021. In the aggregate, this represents $762 million or 3% of the total loan portfolio at March 31, 2021.

•Book value per common share and tangible book value per common share at March 31, 2021 increased to $32.83 and $32.00, respectively, from $32.05 and $31.22, respectively at December 31, 2020 and pre-pandemic levels of $31.33 and $30.52, respectively at December 31, 2019.

•During the three months ended March 31, 2021, the Company repurchased approximately 0.2 million shares of its common stock for an aggregate purchase price of $7.3 million, at a weighted average price of $35.42 per 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 $3.5 million for the three months ended March 31, 2021 and $3.7 million for both the three months ended December 31, 2020 and March 31, 2020. The tax-equivalent adjustment for tax-exempt investment securities was $0.7 million for both the three months ended March 31, 2021 and December 31, 2020; and $0.9 million for the three months ended March 31, 2020.

(2)Annualized.

Three months ended March 31, 2021 compared to the immediately preceding three months ended December 31, 2020

Net interest income, calculated on a tax-equivalent basis, was $200.4 million for the three months ended March 31, 2021 compared to $197.7 million for the three months ended December 31, 2020, an increase of $2.7 million; comprised of decreases in tax-equivalent interest income and interest expense of $5.9 million and $8.6 million, respectively. Decreases in interest income resulted from the impact of repayment of assets originated in a higher rate environment and declines in average loans and investment securities. Declines in interest expense reflected the impact of our strategy focused on lowering the cost of deposits and improving the deposit mix and declines in average interest bearing liabilities. Day count also contributed to the decreases.

The net interest margin, calculated on a tax-equivalent basis, was 2.39% for the three months ended March 31, 2021, compared to 2.33% for the three months ended December 31, 2020. The decline in the average rate paid on interest bearing liabilities, particularly deposits, exceeded the decline in the average yield on interest earning assets.

Offsetting factors contributing to the increase in the net interest margin for the three months ended March 31, 2021 compared to the immediately preceding quarter ended December 31, 2020 included:

•The average rate paid on interest bearing deposits decreased to 0.45% for the three months ended March 31, 2021, from 0.58% for the three months ended December 31, 2020. This decline reflected continued initiatives taken to lower rates paid on deposits, including the re-pricing of term deposits. The cost of deposits is expected to continue to decline.

•The tax-equivalent yield on investment securities decreased to 1.73% for the three months ended March 31, 2021 from 1.82% for the three months ended December 31, 2020. This decrease resulted from the impact of purchases of lower-yielding securities, prepayments of higher yielding mortgage-backed securities and decreases in coupon interest rates on floating rate assets.

•The tax-equivalent yield on loans increased to 3.58% for the three months ended March 31, 2021, from 3.55% for the three months ended December 31, 2020. Accelerated amortization of origination fees on PPP loans that were partially or fully forgiven during the quarter impacted the yield on loans by approximately 0.06% for the quarter ended March 31, 2021 and by 0.03% for the quarter ended December 31, 2020.

•The average rate paid on FHLB and PPPLF borrowings increased to 2.32% for the three months ended March 31, 2021, from 2.07% for the three months ended December 31, 2020, reflecting the maturity of short-term, lower rate FHLB advances and the payoff of all PPPLF borrowings during the fourth quarter of 2020.

•The increase in average non-interest bearing demand deposits as a percentage of average total deposits also positively impacted the cost of total deposits and the net interest margin.

Three months ended March 31, 2021 compared to the three months ended March 31, 2020

Net interest income, calculated on a tax-equivalent basis, was $200.4 million for the three months ended March 31, 2021, compared to $185.2 million for the three months ended March 31, 2020, an increase of $15.2 million; comprised of decreases in tax-equivalent interest income and interest expense of $49.2 million and $64.4 million, respectively. The decrease in interest income reflected the impact of declines in market interest rates, partially offset by the increase in average interest earning assets. The decrease in interest expense reflected declines in both market interest rates and average interest bearing liabilities in addition to continued execution of our strategy focused on reducing the cost of deposits.

The net interest margin, calculated on a tax-equivalent basis, was 2.39% for the three months ended March 31, 2021, compared to 2.35% for the three months ended March 31, 2020. 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 3.58% for the three months ended March 31, 2021, from 4.18% for the three months ended March 31, 2020, while the tax-equivalent yield on investment securities declined to 1.73% from 2.81% for the same periods. Factors contributing to these decreases included the decline in benchmark interest rates, impacting the rates earned on both existing floating rate assets and new production, and repayment of assets originated in a higher rate environment.

•The average rate paid on interest bearing deposits decreased to 0.45% for the three months ended March 31, 2021, from 1.66% for the three months ended March 31, 2020. This decrease reflected declines in market interest rates and continued execution of initiatives taken to lower rates paid on deposits, including the re-pricing of term deposits. The increase in average non-interest bearing demand deposits also positively impacted the net interest margin.

•The average rate paid on notes and other borrowings increased due to the issuance of subordinated notes in June 2020.

Provision for Credit Losses

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

The following table presents the components of the provision for credit losses for the three months ended March 31, 2021 (in thousands):


Amount related to funded portion of loans	$	(26,306)
Amount related to off-balance sheet credit exposures	(1,048)
Amount related to accrued interest receivable	(271)
Amount related to AFS debt securities	(364)
Total recovery of credit losses	$	(27,989)

The recovery of credit losses for the three months ended March 31, 2021 was largely driven by improvements in forecasted economic conditions. For the three months ended December 31, 2020 and March 31, 2020, the Company recorded a recovery of credit losses of $(1.6) million and a provision for credit losses of $125.4 million, respectively. The provision for credit losses for the three months ended March 31, 2020 was impacted by deteriorating current and forecasted economic conditions related to the onset of the COVID-19 pandemic.

The evolving COVID-19 situation and its actual and forecasted impact on economic conditions may continue to lead to volatility in the provision for credit losses.

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.

Non-Interest Income

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


	Three Months Ended March 31,
		2021		2020
Deposit service charges and fees		$	4,900	$	4,186
Gain on sale of loans:

Guaranteed portions of SBA loans		445		1,195
GNMA early buyout loans		1,309		2,255
Other		—		16
Gain on sale of loans, net		1,754		3,466
Gain on investment securities:
Net realized gains on sale of securities AFS		3,967		1,530
Net unrealized losses on marketable equity securities		(1,602)		(4,983)
Gain (loss) on investment securities, net		2,365		(3,453)
Lease financing		12,488		15,481
Other non-interest income		8,789		3,618
		$	30,296	$	23,298

The increase in deposit service charges for the three months ended March 31, 2021 compared to 2020 resulted primarily from higher treasury management fee income.

The decline in gain on sale of GNMA early buyout loans for the three months ended March 31, 2021 compared to the comparable period of the prior year related to lower levels of re-pooling activity. The decrease in gains on the sale of

guaranteed portions of SBA loans for the three months ended March 31, 2021 compared to 2020 was a result of declining origination volume of SBA loans as resources were re-directed to the PPP.

The decrease in income from lease financing for the three months ended March 31, 2021 compared to the three months ended March 31, 2020 was primarily attributed to the increase in operating lease equipment off-lease and re-leasing of assets at lower rates.

The most significant factor leading to the increase in other non-interest income for the three months ended March 31, 2021 compared to the three months ended March 31, 2020 was increased revenue from our customer derivative program.

Non-Interest Expense

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


	Three Months Ended March 31,
		2021		2020
Employee compensation and benefits		$	59,288	$	58,887
Occupancy and equipment		11,875		12,369
Deposit insurance expense		7,450		4,403
Professional fees		1,912		3,204
Technology and telecommunications		15,741		12,596
Depreciation of operating lease equipment		12,217		12,603

Other non-interest expense		14,738		14,806
Total non-interest expense		$	123,221	$	118,868

Deposit insurance expense

Deposit insurance expense increased by $3.0 million for the three months ended March 31, 2021 compared to the three months ended March 31, 2020, reflecting an increase in the assessment rate.

Technology and telecommunications

Technology and telecommunications increased by $3.1 million for the three months ended March 31, 2021 as compared to the three months ended March 31, 2020. This increase is reflective of investments in digital and data analytics capabilities and in the infrastructure to support cloud migration.

Income Taxes

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

Analysis of Financial Condition

Average interest-earning assets increased $2.1 billion to $33.7 billion for the three months ended March 31, 2021 from $31.6 billion for the three months ended March 31, 2020. This increase was driven by a $963 million increase in the average balance of investment securities and a $699 million increase in the average balance of outstanding loans, related in part to PPP loans. Average interest bearing liabilities declined by $1.2 billion for the three months ended March 31, 2021 compared to the three months ended March 31, 2020, while average non-interest bearing deposits increased by $3.1 billion to $7.5 billion for the three months ended March 31, 2021.

Cash and cash equivalents increased by $652 million to $1.0 billion at March 31, 2021, compared to $398 million at December 31, 2020 while total loans declined by $505 million. Total deposits increased by $236 million offset by a decrease of $282 million in borrowings.

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 rental 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, 2021 was 4.7 years and the effective duration of the investment portfolio as of March 31, 2021 was 1.6 years.

The investment securities available for sale portfolio was in a net unrealized gain position of $51.5 million at March 31, 2021, with aggregate fair value equal to 101% of amortized cost. Net unrealized gains at March 31, 2021 included $95.2 million of gross unrealized gains and $43.7 million of gross unrealized losses. Investment securities available for sale in an unrealized loss position at March 31, 2021 had an aggregate fair value of $3.5 billion. The ratings distribution of our AFS securities portfolio at March 31, 2021 is depicted in the chart below:

https://cdn.kscope.io/89ec1d45a113a8fbf9cbff7b1fff84b4-bku-20210331_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, 2021. 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.

The timely payment of principal and interest on securities issued by the U.S. government, U.S. government agencies and U.S. government sponsored enterprises 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.

None of our private label securities in unrealized loss positions had missed principal or interest payments or had been downgraded by a NRSRO at March 31, 2021. 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 severe than our reasonable and supportable economic forecast at March 31, 2021, and incorporated assumptions about voluntary prepayment rates, collateral defaults, delinquencies, severity and other relevant factors. Our analysis also considered the structural characteristics of each security and the level of credit enhancement provided by that structure. Based on the results of this analysis, none of the private label AFS securities in unrealized loss positions were projected to sustain credit losses at March 31, 2021.

The following table presents the distribution of third-party ratings and subordination levels compared to average internal stress scenario losses for the private label CMBS and CLOs at March 31, 2021:


				Subordination						Weighted Average Stress Scenario Loss
	Rating	Percent of Total		Minimum		Maximum		Average
Private label CMBS	AAA	82.4	%	30.0	%	49.8	%	37.9	%	11.1	%

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.

We also have a quarterly price validation process to assess the propriety of the pricing methodologies utilized by our primary pricing services by independently verifying the prices of a sample of securities in the portfolio. Sample sizes vary based on the type of security being priced, with higher sample sizes applied to more difficult to value security types. Verification procedures may consist of obtaining prices from an additional outside source. We have established acceptable percentage deviations from the price provided by the initial pricing source. If deviations fall outside the established parameters, we will obtain and evaluate more detailed information about the assumptions and inputs used by each pricing source or, if considered necessary, employ an additional valuation source to price the security in question. Pricing issues identified through this evaluation are addressed with the applicable pricing service and methodologies or inputs are revised as determined necessary. Depending on the results of the validation process, sample sizes may be extended for particular classes of securities. Results of the validation process are reviewed by the treasury front office and by senior management.

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. We continue to monitor the impact of the

COVID-19 pandemic on markets. While, particularly at the onset of the pandemic, we observed increased volatility and dislocation, we believe the fiscal and monetary response to the crisis has been effective in supporting liquidity and stabilizing markets. To date, circumstances have not led to a change in the categorization of our fair value estimates within the fair value hierarchy.

For additional discussion of the fair values of investment securities, see Note 9 to the consolidated financial statements.

The following table shows the weighted average prospective yields, categorized by scheduled maturity, for AFS investment securities as of March 31, 2021. Scheduled maturities have been adjusted for anticipated prepayments when applicable. Yields on tax-exempt securities have been calculated on a tax-equivalent basis, based on a federal income tax rate of 21%:

For the three months ended March 31, 2021, total loans declined by $505 million. Growth in residential and other consumer loans for the quarter was attributable to GNMA early buyout loans. Residential activity for the three months ended March 31, 2021 included purchases of approximately $578 million in GNMA early buyout loans, offset by approximately $237 million in re-poolings and paydowns. Residential and other consumer loans, excluding GNMA early buyout loans, declined by approximately $107 million.

In the aggregate, commercial loans declined by $739 million for the three months ended March 31, 2021 as the environment remained challenging for new production, line utilization was below historical levels and accelerated prepayment activity continued. MWL line utilization declined seasonally to 55% at March 31, 2021 compared to 62% at December 31, 2020.

We originated $265 million of PPP loans under the Second Draw Program during the three months ended March 31, 2021. Loans originated under the First Draw Program totaling $138 million were fully or partially forgiven during the quarter.

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, 2021		December 31, 2020

1-4 single family residential	$	4,817,116	$	4,922,836
Government insured residential	1,759,289		1,419,074
Other consumer loans	6,042		6,312
	$	6,582,447	$	6,348,222

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, 2021, $512 million or 11% 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 $1.7 billion at March 31, 2021. The Company is not the servicer of these loans.

https://cdn.kscope.io/89ec1d45a113a8fbf9cbff7b1fff84b4-bku-20210331_g3.jpg

Commercial real estate loans include term loans secured by non-owner occupied income producing properties including rental apartments, mixed-use properties, industrial properties, retail shopping centers, free-standing single-tenant buildings, office buildings, warehouse facilities, hotels, real estate secured lines of credit, as well as credit facilities to institutional real estate entities such as REITs and commercial real estate investment funds.

The following table presents the distribution of commercial real estate loans by property type along with weighted average DSCRs and LTVs at March 31, 2021 (dollars in thousands):

DSCRs and LTVs in the table above are based on the most recent information available, which may not be fully reflective of the ultimate impact of the COVID-19 pandemic on borrowers' financial condition or property values.

The Company’s commercial real estate underwriting standards generally provide for loan terms of five to seven years, with amortization schedules of no more than thirty years. LTV ratios are typically limited to no more than 75%. Construction and land loans, included by property type in the table above, represented 1.2% of the total loan portfolio at March 31, 2021.

Included in the table above are approximately $254 million of mixed-use properties in New York, consisting of $187 million categorized as multi-family, $48 million categorized as retail and $19 million categorized as office.

The New York legislature has enacted a number of rent regulation reform measures that generally have the impact of limiting landlords' ability to increase rents on stabilized units and to convert stabilized units to market rate units. The New York multi-family portfolio included $755 million of loans collateralized by properties with some or all of the units subject to rent regulation at March 31, 2021, substantially all of which were stabilized properties.

The following tables present the distribution of stabilized rent-regulated multi-family loans, by DSCR and LTV at March 31, 2021 (in thousands):


DSCR
Less than 1.11	$	290,175
1.11 - 1.24	152,666
1.25 - 1.50	104,986
1.51 or greater	169,378
	$	717,205


LTV
Less than 50%	$	207,391
50% - 65%	284,433
66% - 75%	124,493
More than 75%	100,888
	$	717,205

The LTVs in the table above are based on the most recent appraisal obtained, which may not be fully reflective of changes in valuations that may result from the impact of the rent regulation reforms, or of the COVID-19 pandemic. Loans with DSCR less than 1.11 may be those with temporary rent deferments, unit vacancies or increases in expenses exceeding rental receipts, such as real estate taxes. Certain type of ancillary income may be excluded from the DSCR calculations.

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 and business acquisition finance credit facilities. 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 shared national credits totaling $2.5 billion at March 31, 2021, 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.

The following table presents the exposure in the commercial and industrial portfolio by industry, including $1.9 billion of owner-occupied commercial real estate loans, by industry at March 31, 2021 (in thousands):

Pinnacle provides essential-use equipment financing to state and local governmental entities directly and through vendor programs and alliances. Pinnacle offers a full array of financing structures including equipment lease purchase agreements and direct (private placement) bond re-fundings and loan agreements. Bridge has two operating divisions. The franchise finance division offers franchise acquisition, expansion and equipment financing, typically to experienced operators in well-established concepts. The franchise finance portfolio is made up primarily of quick service restaurant and fitness concepts comprising 58% and 34% of the portfolio, respectively. The equipment finance division provides primarily transportation equipment financing through a variety of loan and lease structures. The Bank also engages in mortgage warehouse lending on a national basis.

The Company has originated PPP loans under both the First and Second Draw Programs. These loans bear interest at 1% and are guaranteed as to principal and interest by the SBA. PPP loans have terms of 2 and 5 years under the First and Second Draw Programs, respectively , and are eligible for earlier forgiveness under the terms of the PPP in prescribed circumstances.

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. In response to the COVID-19 pandemic, we have further enhanced our workout and recovery staffing and processes. 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 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, operating losses, increasing balance sheet leverage, project cost overruns, unreasonable construction delays, exhausted interest reserves, declining collateral values, frequent overdrafts or past due real estate taxes. Loans with weaknesses so severe that collection in full is highly questionable or improbable, but because of certain reasonably specific pending factors have not been charged off, are assigned an internal risk rating of doubtful. During 2020, risk ratings were re-evaluated for a substantial portion of the commercial portfolio, with a particular focus on portfolio segments we identified for enhanced monitoring and loans for which we granted temporary payment deferrals or modifications in light of the COVID-19 pandemic. We continue to closely monitor the risk rating of commercial loans in light of the evolving COVID-19 situation.

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


	March 31, 2021				December 31, 2020	December 31, 2019

Our internal risk ratings at March 31, 2021 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. Management has taken what we believe to be a proactive and objective approach to risk rating the commercial loan portfolio since the onset of the pandemic. The increase in levels of criticized and classified loans, particularly in the special mention and substandard accruing categories, over the course of 2020 was directly related to the impact of the COVID-19 pandemic. During the three months ended March 31, 2021, total criticized and classified assets declined by $74.8 million; however, there was continued migration into the substandard accruing category. 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 a decline in the level of criticized and classified assets over the remainder of 2021. However, uncertainty remains around the future trajectory of the COVID-19 pandemic, the roll-out of vaccines and related economic and social impacts. In light of that uncertainty, it is possible that criticized and classified asset levels will not decline or that they may increase.

The following table provides additional information about special mention and substandard accruing loans, at the dates indicated (dollars in thousands). Non-performing loans are discussed further in the section entitled "Non-performing Assets" below.

For commercial borrowers, payment deferrals were generally deferrals of principal and/or interest payments for up to two periods of 90 days each. The deferred payments along with interest accrued during the deferral period are generally due and payable on the maturity date. CARES Act modifications represent longer-term modifications and most commonly have taken the form of 9 to 12 month interest only periods. The majority of loan modifications or deferrals and payment deferrals that took place after the onset of the COVID-19 pandemic have not been categorized as TDRs, in accordance with interagency and authoritative guidance and the provisions of the CARES Act.

The following table presents additional information, as of March 31, 2021, about loan portfolio sub-segments that, in light of the COVID-19 pandemic, were identified for enhanced monitoring (dollars in thousands):

At March 31, 2021, 76% of commercial loans on deferral or modified due to the COVID-19 pandemic and 52% of criticized and classified assets were in the above portfolio sub-segments.

Retail Exposure in the CRE Portfolio

The predominant collateral types supporting this sub-segment include both anchored and unanchored suburban and urban retail properties, some single tenant properties as well as some mixed-use properties in New York City with a significant retail component. We have no significant large shopping mall or "big box" exposure. The weighted average LTV for this sub-segment is 58%, based on the most recently available information.

Retail Exposure in the C&I Portfolio

This is a well-diversified sub-segment by industry. The largest exposure is to gas stations, generally with convenience stores, representing $85 million, or 28% of the sub-segment. 64% of loans in this sub-segment are collateralized by owner-occupied real estate.

Hotel

Many hotels experienced significant disruption in revenue due to social distancing measures arising from the pandemic. The weighted average LTV for this sub-segment is 63%, based on the most recent information available. The majority of our hotel exposure is in Florida at 74%, followed by 16% in New York. This sub-segment includes $60 million in SBA loans. All but one of our hotel collateral properties have now re-opened for business.

Airlines and Aviation Authorities

These borrowers have directly benefited from government relief programs enacted in response to the COVID-19 pandemic.

Operating Lease Equipment, net

Six operating leases with a carrying value of assets under lease totaling $39 million, all of which were exposures to the energy industry, were internally risk rated substandard at March 31, 2021. 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. During the three months ended March 31, 2021 and 2020, impairment charges recognized related to operating lease equipment were insignificant.

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 through impairment of asset carrying values.

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, including events such as the COVID-19 pandemic. 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 utilizing 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 $321 million at March 31, 2021. The majority of the energy exposure was in the operating lease equipment portfolio where energy exposure totaled $273 million. The remaining energy exposure, totaling approximately $48 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, 2021:

https://cdn.kscope.io/89ec1d45a113a8fbf9cbff7b1fff84b4-bku-20210331_g5.jpg

FICO scores are generally updated at least annually, and were most recently updated in the first quarter of 2021. LTVs are typically based on valuation at origination since we do not routinely update residential appraisals.

At March 31, 2021, the majority of the 1-4 single family residential loan portfolio, excluding government insured residential loans, was owner-occupied, with 81% primary residence, 8% second homes and 11% investment properties.

1-4 single family residential loans, excluding government insured residential loans, past due more than 30 days totaled $81 million and $66 million March 31, 2021 and December 31, 2020, respectively. The amount of these loans 90 days or more past due was $16.2 million and $9.2 million at March 31, 2021 and December 31, 2020, respectively. Delinquency statistics as of March 31, 2021 may not be fully reflective of the impact of the COVID-19 pandemic on residential borrowers due to payment deferral programs. Loans on deferral that are in compliance with the terms of the deferral program are not reported as delinquent.

At March 31, 2021, $106 million or 2% of 1-4 single family residential loans, excluding government insured residential loans, were under short-term deferral or modified due to the COVID-19 pandemic. Through March 31, 2021, $525 million of residential loans, excluding government insured loans, had been granted at least one short term payment deferral. The following table presents information about residential loans granted payment deferrals as a result of the COVID-19 pandemic as of March 31, 2021, excluding government insured residential loans (dollars in thousands):


			Loans That Have Rolled Off of Short-Term Deferral
Loans Still Under Short-Term Deferral			Paid Off or Paying as Agreed			Not Resumed Regular Payments
Balance		% of Loans Initially Granted Short-Term Deferral(1)	Balance		% of Loans Rolled Off Short-Term Deferral	Balance		% of Loans Rolled Off Short-Term Deferral
$	90,811	17%	$	408,569	94%	$	26,134	6%

(1) Includes $18 million of loans continuing to make payments

For residential borrowers, relief has typically initially taken the form of 90 day payment deferrals, with deferred payments due at the end of the 90 day period. At the end of the initial 90 day deferral period, residential borrowers may either (i) make all payments due, (ii) be granted an additional deferral period or (iii) enter into a modification or repayment plan.

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

Non-Performing Assets

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

The following table and charts summarize the Company's non-performing loans and non-performing assets at the dates indicated (dollars in thousands):

(1) Non-performing loans and assets include the guaranteed portion of non-accrual SBA loans totaling $48.2 million or 0.21% of total loans and 0.14% of total assets, at March 31, 2021; compared to $51.3 million or 0.22% of total loans and 0.15% of total assets, at December 31, 2020.

(2) Annualized for March 31, 2021.

Contractually delinquent government insured residential loans 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 more than 90 days was $629 million and $562 million at March 31, 2021 and December 31, 2020, respectively. Decreases in the ratios of the ACL to total loans and the ACL to non-performing loans at March 31, 2021 compared to December 31, 2020 are attributable to the recovery of credit losses recorded during the three months ended March 31, 2021, which resulted primarily from an improving economic forecast.

The following chart presents trends in non-performing loans and non-performing assets. The increase in the non-performing loan and non-performing asset ratios compared to pre-pandemic levels is reflective of the impact of the COVID-19 pandemic.

The ultimate impact of the COVID-19 pandemic on non-performing asset levels and net charge-offs may be delayed in the near-term due to government assistance and loan deferral programs.

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

TDRs

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

Under recently issued inter-agency and authoritative guidance and consistent with the CARES Act, short-term (generally periods of six months or less) deferrals or modifications related to COVID-19 will typically not be categorized as TDRs. Additionally, section 4013 of the CARES Act, as amended by the Consolidated Appropriations Act on December 27, 2020, effectively suspended the guidance related to TDRs codified in ASC 310-40 until the earlier of January 1, 2022 or sixty days after the date of the suspension of the declared state of emergency related to the COVID-19 pandemic. None of the COVID-19 related deferrals the Company has granted to date that fall under these provisions have been categorized as TDRs. See the sections entitled "Asset Quality - Commercial Loans - Payment Deferrals" and "Asset Quality - Residential and Other Consumer Loans" for further discussion.

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


	March 31, 2021					December 31, 2020

	Number of TDRs	Amortized Cost		Related Specific Allowance		Number of TDRs	Amortized Cost		Related Specific Allowance

(1) Includes 342 government insured residential loans modified in TDRs totaling $55.4 million at March 31, 2021; and 326 government insured residential loans modified in TDRs totaling $52.8 million at December 31, 2020.

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, we have temporarily suspended new residential foreclosure actions.

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. Under the inter-agency guidance and consistent with the CARES Act, deferrals or modifications related to COVID-19 will generally not be categorized as TDRs. Loans subject to these temporary deferrals or modifications, if in compliance with the contractual terms of the deferral or modification agreements, will typically not be reported as past due.

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. Uncertainty remains around the impact the COVID-19 crisis will have on the economy broadly, and on our borrowers specifically. In light of this uncertainty, 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, and in loan portfolio composition, as well as 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. Variables with the most significant impact on the commercial real estate model include unemployment, the CRE property forecast by property type, 10 year treasury yield, Baa corporate yield and real GDP growth. Those with the most significant impact on the commercial model include a stock market volatility index, the S&P 500 index, unemployment and a variety of interest rates and spreads. Those with the most significant impact on the residential model include HPI, unemployment, real GDP growth, and a 30 year mortgage rate. 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.

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 2020 Annual report on Form 10-K for more detailed information about our ACL methodology.

The following table provides an analysis of the ACL, provision for credit losses related to the funded portion of loans and net charge-offs by loan segment for the periods indicated (in thousands):

Changes in the ACL during the three months ended March 31, 2021

The decrease in the ACL from December 31,2020 to March 31, 2021 for the majority of portfolio sub-segments resulted largely from an improving economic forecast. The decrease was primarily related to the pass rated portion of the portfolio. The ACL for pass-rate loans, including residential loans, declined to $93 million at March 31, 2021 from $137 million at December 31, 2020. The ACL for non-pass rated loans increased to $128 million at March 31, 2021 from $120 million at December 31, 2020.

Some of the data points informing the reasonable and supportable economic forecast used in estimating the ACL at March 31, 2021 were:

•National unemployment at 6.0% for the second quarter of 2021, steadily declining to 5% through the end of 2021, and declining to 4.2% by the end of 2022;

•Annualized growth in GDP at 6.2% for the second quarter of 2021, increasing to 7.1% by the end of 2021, and 2.3% for 2022;

•VIX trending at stabilized levels through the forecast horizon; and

•S&P 500 averaging near 3,700 through the reasonable and supportable forecast period.

In the aggregate, the ACL for the CRE portfolio sub-segment, including multi-family, non-owner occupied CRE and construction and land, decreased by $9.5 million from December 31, 2020, from 1.52% to 1.43% of loans. Multi-family loans increased by $5.9 million, primarily due to the increase of $74 million in substandard accruing loans in the segment during the three months ended March 31, 2021.

In addition to the impact of the economic forecast, the decline in the ACL for the Bridge franchise portfolio reflects a reduction in the level of criticized and classified assets and charge-offs taken during the quarter.

Borrowings

In addition to deposits, we utilize FHLB advances as a funding source; the advances provide us with additional flexibility in managing both term and cost of funding and in managing interest rate risk. FHLB advances are secured by qualifying residential first mortgage and commercial real estate loans, and MBS. The following table presents information about the contractual balance of outstanding FHLB advances as of March 31, 2021 (dollars in thousands):

Capital Resources

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, 2021 and December 31, 2020, The Company and the Bank had capital levels that exceeded both the regulatory well-capitalized guidelines and all internal capital ratio targets.

The following table provides information regarding regulatory capital for the Company and the Bank as of March 31, 2021 (dollars in thousands):

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

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

We believe we are well positioned, from a capital perspective, to withstand a severe downturn in the economy. In light of the COVID-19 crisis, uncertainty around its ultimate impact on the economy and, by extension, on our financial condition and results of operations, we have enhanced our stress testing framework. We have increased both the frequency of stress testing, which is performed at least quarterly, and the spectrum of scenarios utilized. One exercise we completed was to stress our March 31, 2020 loan portfolio using both the 2018 DFAST severely adverse scenario and the 2020 DFAST severely adverse scenario. The results of each of these stress tests projected regulatory capital ratios in excess of all well capitalized thresholds.

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. The Company demonstrated its ability to access the capital markets in a period of stress with its June, 2020 subordinated debt issuance.

Liquidity

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. For the three months ended March 31, 2021 and 2020 net cash provided by operating activities was $386 million and $64 million respectively.

The onset of the COVID-19 pandemic led to dislocation and volatility in funding and capital markets and evoked widespread concerns about the ongoing functioning of those markets, the availability of liquidity and the economy generally. In response, the Federal Reserve reduced its benchmark interest rate to a target level of 0 - 0.25% and has maintained it at that level to date, actively adjusted the size of its overnight and term repurchase agreement operations, reduced reserve requirements to zero, lowered the cost of discount window borrowings, encouraged banks to utilize the discount window and committed to purchasing large amounts of U.S. Treasury securities and MBS. The U.S. government implemented an unprecedented variety of additional stimulus and measures to support markets, the flow of credit, and systemic liquidity. These actions appear to have been effective in stabilizing market liquidity.

In response to the onset of COVID-19 and potential concerns that might arise about the stability of liquidity, we initially took a number of precautionary measures to ensure adequacy of liquidity. We took steps to optimize available same day liquidity. We increased the level of cash held on balance sheet, to be prepared to meet potential increased demand for deposit withdrawals and line usage, which to date have not materialized. While we took proactive steps to be prepared for disruptions in liquidity, the COVID-19 pandemic has not been a liquidity event; we have not experienced unusual volatility or stress on our liquidity position to date.

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. Since the onset of the COVID-19 pandemic, we have not experienced unusual deposit outflows or volatility; we have, in fact experienced growth in deposits. Credit line usage, which we have monitored regularly since the onset of COVID-19, never significantly exceeded and is currently below our trailing three year average. Our available liquidity may also change as the FHLB and Federal Reserve Bank reprice our collateral in the normal course of business based on ongoing quarterly valuations. Based on our internal analysis, we do not expect this to negatively impact our overall liquidity position.

The ALCO policy has established several measures of liquidity which are typically monitored monthly by the ALCO and quarterly by the Board of Directors. In light of the COVID-19 situation, we have enhanced the frequency and extent of liquidity monitoring and reporting.

The ALCO policy establishes limits for the ratio of available liquidity to volatile liabilities, the ratio of wholesale funding to total assets, the ratio of brokered deposits to total deposits and a government backed securities holding ratio, measured as the ratio of U.S. Government backed securities to total securities. At March 31, 2021 BankUnited was in compliance with all of these ALCO policy limits.

An additional primary measure of liquidity monitored by management is the 30-day total liquidity ratio, defined as (a) the sum of cash and cash equivalents, pledgeable securities and a measure of funds expected to be generated by operations over the next 30 days; divided by (b) the sum of potential deposit runoff, liabilities maturing within the 30 day time frame and a measure of funds expected to be used in operations over the next 30 days. ALCO policy thresholds stipulate that BankUnited’s liquidity is considered acceptable if the 30-day total liquidity ratio exceeds 100%. At March 31, 2021, BankUnited’s 30-day total liquidity ratio was 253%. Management also monitors a one-year liquidity ratio, defined as (a) cash and cash equivalents, pledgeable securities, unused borrowing capacity at the FHLB, and loans and non-agency securities maturing within one year; divided by (b) forecasted deposit outflows and borrowings maturing within one year. This ratio allows management to monitor liquidity over a longer time horizon. The acceptable threshold established by the ALCO for this liquidity measure is 100%. At March 31, 2021, BankUnited’s one-year liquidity ratio was 377%. Additional measures of liquidity regularly monitored by the ALCO include the ratio of FHLB advances to total funding, concentrations of large deposits, a measure of on balance sheet available liquidity 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. The Company also 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 requirements will continue to be satisfied over the next 12 months through the sources of funds described above.

Interest Rate Risk

A principal component of the Company’s risk of loss arising from adverse changes in the fair value of financial instruments, or market risk, is interest rate risk, including the risk that assets and liabilities with similar re-pricing characteristics may not reprice at the same time or to the same degree. A primary objective of the Company’s asset/liability management activities is to maximize net interest income, while maintaining acceptable levels of interest rate risk. The ALCO is responsible for establishing policies to limit exposure to interest rate risk, and to ensure procedures are established to monitor compliance with these policies. The thresholds 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, we are modeling instantaneous rate shocks of plus 100, plus 200, plus 300 and plus 400 basis point shifts as well as 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 Company’s ALCO policy provides that net interest income sensitivity will be considered acceptable if decreases in forecast net interest income in specified parallel rate shock scenarios, generally by policy plus and minus 100, 200, 300 and 400 basis points, are within specified percentages of forecast net interest income in the most likely rate scenario over the next twelve months and in the second year. At March 31, 2021, the most likely rate scenario assumed that all indices are floored at 0%. We did not apply the falling rate scenarios at March 31, 2021 due to the low level of current interest rates. The following table illustrates the thresholds set forth in the ALCO policy and the impact on forecasted net interest income in the indicated simulated scenarios at March 31, 2021 and December 31, 2020:


	Down 100		Plus 100		Plus 200		Plus 300		Plus 400
Policy Thresholds:
In year 1	(6.0)	%	(6.0)	%	(10.0)	%	(14.0)	%	(18.0)	%
In year 2	(9.0)	%	(9.0)	%	(13.0)	%	(17.0)	%	(21.0)	%
Model Results at March 31, 2021 - increase:
In year 1	N/A		3.8	%	6.6	%	8.3	%	9.4	%
In year 2	N/A		6.7	%	11.6	%	15.8	%	19.4	%
Model Results at December 31, 2020 - increase:
In year 1	N/A		2.9	%	3.9	%	3.2	%	1.9	%
In year 2	N/A		5.0	%	7.8	%	9.0	%	9.5	%

Management also simulates changes in EVE in various interest rate environments. The ALCO policy has established parameters of acceptable risk that are defined in terms of the percentage change in EVE from a base scenario under eight rate scenarios, derived by implementing immediate parallel movements of plus and down 100, 200, 300 and 400 basis points from current rates. We did not simulate decreases in interest rates at March 31, 2021 due to the currently low level of market interest rates. The following table illustrates the acceptable thresholds as established by ALCO and the modeled change in EVE in the indicated scenarios at March 31, 2021 and December 31, 2020:


	Down 100		Plus 100		Plus 200		Plus 300		Plus 400
Policy Thresholds	(9.0)	%	(9.0)	%	(18.0)	%	(27.0)	%	(36.0)	%
Model Results at March 31, 2021 - increase (decrease):	N/A		1.3	%	0.2	%	(1.6)	%	(3.6)	%
Model Results at December 31, 2020 - increase (decrease):	N/A		0.8	%	(2.0)	%	(6.1)	%	(10.0)	%

These measures fall within an acceptable level of interest rate risk per the thresholds established in the ALCO policy.

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 borrowings and to changes in the fair value of fixed rate borrowings, 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, 2021, outstanding interest rate swaps and caps designated as cash flow hedges had an aggregate notional amount of $2.8 billion and outstanding interest rate swaps designated as fair value hedges had an aggregate notional amount of $200 million. At March 31, 2021, the aggregate fair value of interest rate swaps and caps designated as cash flow hedges included in other assets and other liabilities was $2.0 million and $5.1 million, respectively.

Interest rate swaps and caps not designated as hedges had an aggregate notional amount of $3.4 billion at March 31, 2021. The aggregate fair value of these interest rate swaps and caps included in other assets was $75.7 million and the aggregate fair value included in other liabilities was $34.5 million. 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.

Non-GAAP Financial Measures

PPNR is a non-GAAP financial measure. Management believes this measure is relevant to understanding the performance of the Company attributable to elements other than the provision for credit losses and the ability of the Company to generate earnings sufficient to cover estimated credit losses, particularly in view of the volatility of the provision for credit losses resulting from the COVID-19 pandemic. This measure also provides a meaningful basis for comparison to other financial institutions since it is commonly employed and is a measure frequently cited by investors and analysts. The following table reconciles the non-GAAP financial measurement of PPNR to the comparable GAAP financial measurement of income (loss) before income taxes for the periods indicated (in thousands):


	Three Months Ended
	March 31, 2021		December 31, 2020		March 31, 2020
Income (loss) before income taxes (GAAP)	$	131,304	$	106,965	$	(40,422)
Plus: Provision for (recovery of) credit losses	(27,989)		(1,643)		125,428
PPNR (non-GAAP)	$	103,315	$	105,322	$	85,006

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):


	March 31, 2021		December 31, 2020		December 31, 2019
Total stockholders’ equity	$	3,061,835	$	2,983,012	$	2,980,779

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

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

During the quarter ended March 31, 2021, 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. We have focused on insuring that our technology systems and internal controls continue to operate effectively in a remote work environment and have not identified any instances in which our control environment has failed to operate effectively. We are continually monitoring and assessing any impact of the COVID-19 situation on our internal controls to address impacts to their design, implementation and operating effectiveness.

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
