The Bank also offers certain commercial lending and deposit products through national platforms.
In connection with the FSB Acquisition, BankUnited entered into two loss sharing agreements with the FDIC. The Loss Sharing Agreements consist of the Single Family Shared-Loss Agreement and the Commercial Shared-Loss Agreement. Assets covered by the Loss Sharing Agreements are referred to as covered assets or, in certain cases, covered loans. The Single Family Shared-Loss Agreement provides for FDIC loss sharing and the Bank’s reimbursement for recoveries to the FDIC through May 21, 2019 for single family residential loans and OREO. Loss sharing under the Commercial Shared-Loss Agreement terminated on May 21, 2014. The Commercial Shared-Loss Agreement continued to provide for the Bank’s reimbursement of recoveries to the FDIC through June 30, 2017 for all other covered assets, including commercial real estate, commercial and industrial and consumer loans, certain investment securities and commercial OREO. Pursuant to the terms of the Loss Sharing Agreements, the covered assets are subject to a stated loss threshold whereby the FDIC will reimburse BankUnited for 80% of losses related to the covered assets up to $4.0 billion and 95% of losses in excess of this amount, beginning with the first dollar of loss incurred.
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, theythese 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, 20162021 filed with the SEC. In the opinion of management, all adjustments, consisting of normal recurring adjustments, considered necessary for a fair presentation have been included. Operating results for the three and nine months ended September 30, 2017March 31, 2022 are not necessarily indicative of the results that may be expected in future periods.
Certain amounts presented for prior periods have been reclassified to conform to the current period presentation.The Company has a single reportable segment.
Accounting Estimates
In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, and expenses and disclosures of contingent assets and liabilities. Actual results could differ significantly from these estimates.
Significant estimates includeThe most significant estimate impacting the ALLL,Company's consolidated financial statements is the amount and timing of expected cash flows from covered assets and the FDIC indemnification asset, and the fair values of investment securities and other financial instruments. Management has used information provided by third party valuation specialists to assist in the determination of the fair values of investment securities.ACL.
New Accounting Pronouncements Adopted During the Three Months Ended March 31, 2022
ASU No. 2016-09, Compensation2020-06, Debt - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment AccountingDebt 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 simplified severalalso revise certain aspects of the accounting for share-based payment transactions.guidance on calculating earnings per share with respect to convertible instruments and instruments that may be settled in the entity's own shares. The Company adopted this ASU on January 1, 2022, with no material impact on the Company's consolidated financial position, results of operations, and cash flows.
ASU No. 2022-01, Fair Value Hedging—Portfolio Layer Method(Topic 815). This ASU expands the portfolio layer method of hedge accounting prescribed in ASU No. 2017-12 to allow multiple hedged layers of a single closed portfolio and to include portfolios of both prepayable and non-prepayable financial assets. This scope expansion is consistent with the FASB’s efforts to simplify hedge accounting and allows entities to apply the same accounting method to similar hedging strategies. The ASU also specifies eligible hedging instruments in a single-layer hedge, provides additional guidance on accounting and disclosure of hedge basis adjustments and specifies how hedge basis adjustments should be considered in determining credit losses for assets in the first quarter of 2017.designated closed portfolio. This ASU is effective for public business entities for interim and annual periods in fiscal years beginning after December 15, 2022. The amendment requiring the recognition of excess tax benefits and deficiencies as income tax benefit or expenseCompany adopted this ASU upon its release in the income statement as opposed to being recognized as additional paid-in-capital was applied prospectively and resulted in the recognition of $0.3 million and $3.2 million in excess tax benefits in the consolidated statement of income line item "Provision for income taxes" for the three and nine months ended September 30, 2017, increasing net income by the same amount in each period. The adoption hadMarch 2022 with no material impact on basic and diluted earnings per share for the three months ended September 30, 2017 and increased basic and diluted earnings per share by $0.02 and $0.03, respectively, for the nine months ended September 30, 2017. The Company retrospectively adopted the amendments requiring the classificationCompany's consolidated financial position, results of excess tax benefits and deficiencies with other income tax cash flows as operating activitiesoperations, and cash paid when directly withholding shares as financing activities in the accompanying consolidated statements of cash flows; the impact was not material.

Accounting Pronouncements Not Yet Adopted
ASU No. 2017-08, Receivables—Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable2022-02, Financial Instruments—Credit Losses (Topic 326). This ASU eliminates the accounting guidance for TDRs by creditors in Subtopic 310-40, Receivables - Troubled Debt Securities.Restructurings by Creditors. The amendments in this ASU require certain premiums on callable debt securities to be amortized to the earliest call date. The amortization period for callable debt securities purchased as a discount will not be impacted. The Company early-adopted this ASU in the first quarter of 2017 with no material impact on the Company's consolidated financial position, results of operations or cash flows.
ASU No. 2016-06, Derivatives and Hedging (Topic 815):Contingent Put and Call Options in Debt Instruments. The amendments in this ASU clarify theenhances disclosure requirements for assessing whether contingent call (put) options that can accelerate the payment of principal on debt instruments are clearlycertain loan refinancings and closelyrestructurings by creditors when a borrower is experiencing financial difficulty, updates certain requirements related to their debt hosts. A company performing the assessmentaccounting for credit losses under these amendmentsASC 326 and requires disclosure of current-period gross write offs of financing receivables by year of origination. The ASU is required to assess the embedded call (put) options solely in accordance with a four-step decision sequence, without also considering whether the contingency is related to interest rates or credit risks. The Company adopted this ASU in the first quarter of 2017 with no impact on its consolidated financial position, results of operations or cash flows.
ASU No. 2017-04, Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment, an amendment to simplify the subsequent quantitative measurement of goodwill by eliminating step two from the goodwill impairment test. As amended, an entity recognizes an impairment charge for the amount by which the carrying amount of a reporting unit exceeds its fair value, not to exceed the total amount of goodwill allocated to the reporting unit. An entity still has the option to perform the qualitative test for a reporting unit to determine if the quantitative impairment test is necessary. The Company early adopted this ASU in the third quarter of 2017, concurrent with performance of its annual goodwill impairment test, with no impact on its consolidated financial position, results of operations or cash flows.
ASU No. 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. The new guidance eliminates the requirement to separately measure and report hedge ineffectiveness after initial qualification. For qualifying cash flow and net investment hedges, this means that the entire change in the fair value of the hedging instrument included in the assessment of hedge effectiveness will be recorded in other comprehensive income (OCI), and amounts deferred in OCI will be reclassified to earnings in the same income statement line item that is used to present the earnings effect of the hedged item when the hedged item affects earnings. The Company will have until the end of the first quarter in which a hedge is designated to perform an initial assessment of a hedge’s effectiveness. The new guidance also permits a qualitative effectiveness assessment for certain hedges instead of a quantitative test, such as a regression analysis, if the company can reasonably support an expectation of high effectiveness throughout the term of the hedge. In addition, in order to better align an entity's risk management activities and financial reporting for hedging relationships, the ASU allows for more hedging strategies to be eligible for hedge accounting. From a disclosure standpoint, to help users of the financial statements better understand the effects of hedge accounting, the guidance requires revised tabular disclosures that focus on the effect of hedge accounting by income statement line, and eliminates today’s requirement to disclose hedge ineffectiveness because this amount is no longer separately measured. The Company early adopted this ASU during the quarter ended September 30, 2017 with no material impact on the Company's consolidated financial position, results of operations or cash flows.
Recent Accounting Pronouncements
In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), which will supersede the revenue recognition requirements in Topic 605, Revenue Recognition, and most industry-specific revenue recognition guidance throughout the Accounting Standards Codification. The amendments in this update affect any entity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of non-financial assets unless those contracts, including leases and insurance contracts, are within the scope of other standards. The amendments establish a core principle requiring the recognition of revenue to depict the transfer of goods or services to customers in an amount reflecting the consideration to which the entity expects to be entitled in exchange for such goods or services. The amendments also require expanded disclosures concerning the nature, amount, timing and uncertainty of revenues and cash flows arising from contracts with customers. Financial instruments and lease contracts are generally outside the scope of the ASU as are revenues that are in the scope of ASC 860 "Transfers and Servicing", ASC 460 "Guarantees" and ASC 815 "Derivatives and Hedging". The FASB has issued subsequent ASUs to clarify certain aspects of ASU 2014-09, without changing the core principle of the guidance and to defer the effective date of ASU 2014-09 to annual periods and interim periods within fiscal years beginning after December 15, 2017. Although management has not finalized its evaluation of the impact of adoption of this ASU, substantially all of the Company's revenues have historically been, and are expected to continue to be, generated from activities that are outside the scope of the ASU. Therefore, management does not expect adoption to have a material impact on the Company's consolidated financial position, results of operations or cash flows.

Service charges on deposit accounts, which totaled approximately $9.8 million for the nine months ended September 30, 2017, is the most significant category of revenue identified as within the scope of the ASU; management does not expect the amount and timing of recognition of such revenue to be materially impacted by adoption, which management expects to apply using the modified retrospective approach, whereby the cumulative effect of initially applying the amendments is recognized as an adjustment to opening retained earnings at the date of adoption.
In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. The amendments in the ASU that are expected to be most applicable to the Company (1) eliminate the available for sale classification for equity securities and require investments in equity securities (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income, provided that equity investments that do not have readily determinable fair values may be re-measured at fair value upon occurrence of an observable price change or recognition of impairment, (2) eliminate the requirement to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet, and (3) require public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes. The amendments also clarify that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available for sale securities in combination with the entity's other deferred tax assets, which is consistent with the Company's current practice. The amendments in this ASU are effective for the Company for interim and annual periods in fiscal years beginning after December 15, 2017 and will be adopted by means of a cumulative-effect adjustment to the balance sheet, except for amendments related to equity securities without readily determinable fair values, which will be applied prospectively. Although management has not finalized its evaluation of the impact of adoption of this ASU, adoption is not expected to have any impact on the Company's consolidated financial position or cash flows, other than a cumulative effect adjustment to reclassify any unrealized gains or losses related to equity securities from AOCI to retained earnings.2022. The carrying value of equity investments for which fair value changes will be recognized in earnings after adoption totaled $71 million and had unrealized gains of $10.0 million at September 30, 2017. Adoption of the ASU will impact the Company's disclosures about the fair value of certain financial instruments.
In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). The amendments in this ASU require a lessee to recognize in the statement of financial position a liability to make lease payments and a right-of-use asset representing its right to use the underlying asset for leases with terms longer than one year. Accounting applied by lessors is largely unchanged by this ASU. The amendments in this ASU are effective for the Company for interim and annual periods in fiscal years beginning after December 15, 2018. Early adoption is permitted; however, the Company does not intend to early adopt this ASU. Lessees and lessors are required to apply the provisions of the ASU at the beginning of the earliest period presented using a modified retrospective approach. Management has not completed its evaluation of the impact of adoption of this ASU, and is not currently able to reasonably estimatehowever, the impact of adoption on the consolidated financial statements; however, the most significant impact is expected to be the recognition, as lessee, of new right-of-use assets and lease liabilities on the consolidated balance sheet for real estate leases currently classified as operating leases.
In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326); Measurement of Credit Losses on Financial Instruments. The ASU introduces new guidance which makes substantive changes to the accounting for credit losses. The ASU introduces the CECL model which applies to financial assets subject to credit losses and measured at amortized cost, as well as certain off-balance sheet credit exposures. This includes loans, loan commitments, standby letters of credit, net investments in leases recognized by a lessor and held-to-maturity debt securities. The CECL model requires an entity to estimate credit losses expected over the life of an exposure, considering information about historical events, current conditions and reasonable and supportable forecasts. The ASU also modifies the current OTTI model for available for sale debt securities requiring an estimate of expected credit losses only when the fair value of an available for sale debt security is below its amortized cost. Credit losses on available for sale debt securities will be limited to the difference between the security's amortized cost basis and its fair value. The ASU also provides for a simplified accounting model for purchased financial assets with more than insignificant credit deterioration since their origination. The amendments in this ASU are effective for the Company for interim and annual periods in fiscal years beginning after December 15, 2019. Management has not yet completed its evaluation of the impact of adoption of this ASU and is not currently able to reasonably estimate the impact of adoption on the consolidated financial statements; however, adoption is likely to lead to significant changes in accounting policies related to, and the methods employed in estimating, the ALLL. It is possible that the impact will be material to the Company's consolidated financial position, and results of operations.

In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receiptsoperations, and Cash Payments. The amendments in this ASU provide guidance on eight specific cash flow classification issues where there has been diversity in practice. The guidance in the ASU that is expected to be most applicable to the Company requires: (1) cash payments for debt prepayment or extinguishment costs to be classified as cash outflows for financing activities, (2) proceeds from settlement of insurance claims to be classified on the basis of the nature of the loss and (3) cash proceeds from settlement of bank-owned life insurance policies to be classified as cash flows from investing activities. Cash payments for premiums on bank-owned life insurance may be classified as cash flows for investing activities, operating activities or a combination thereof. The amendments in this ASU are effective for the Company for interim and annual periods in fiscal years beginning after December 15, 2017 and will be applied retrospectively to each period presented. The provisions of this ASU are generally consistent with the Company's current practice and adoption is not expected to materially impactbe material. Adoption will lead to additional and revised disclosures in the Company's consolidated cash flows.financial statements.

The Company monitors its investment securities available for sale for OTTIcredit loss impairment on an individual security basis. No securities were determined to be other-than-temporarilycredit loss impaired during the ninethree months ended September 30, 2017. TheMarch 31, 2022 and 2021. At March 31, 2022, the Company doesdid not intendhave an intent to sell securities that arewere in significant unrealized loss positions at September 30, 2017 and it iswas not more likely than not that the Company willwould be required to sell these securities before recovery of the amortized cost basis, which may be at maturity. In making this determination, the Company considered its current and projected liquidity position, its investment policy as to permissible holdings and concentration limits, regulatory requirements and other relevant factors.
At September 30, 2017, 54March 31, 2022, 419 securities available for sale were in unrealized loss positions. The amount of impairment related to 2089 of these securities was considered insignificant both individually and in the aggregate, totaling approximately $237 thousand$0.7 million and no further analysis with respect to these securities was considered necessary.
The basis for concluding that impairment of the remainingAFS securities were not credit loss impaired and no ACL was not other-than-temporaryconsidered necessary at March 31, 2022 is further described below:discussed below.
Unrealized losses were generally attributable to rising interest rates and, to a lesser extent, widening spreads related to the Federal Reserve's plans for quantitative tightening and benchmark interest rate increases. Continuing supply-chain disruptions, inflationary indicators and geopolitical events have also led to market uncertainty, producing some yield curve dislocations.
U.S. Government agencyAgency and sponsored enterprise residentialMBSand commercial MBSGovernment Sponsored Enterprise Securities
At September 30, 2017, eightMarch 31, 2022, 5 U.S. treasury, NaN U.S. Government agency and sponsored enterprise residential MBS, and fourNaN U.S. Government agency and sponsored enterprise commercial MBS, and 10 SBA securities were in unrealized loss positions. For five fixed rate securities, the impairment was primarily attributable to an increase in medium and long-term market interest rates subsequent to the date of acquisition. For the remaining seven variable rate securities, the amount of impairment was less than 1% of amortized cost. The timely payment of principal and interest on these securities is explicitly or implicitly guaranteed by the U.S. Government. GivenAs such, there is an assumption of zero credit loss and the expectationCompany expects to recover the entire amortized cost basis of timely paymentthese securities.
Private Label Securities:
None of the impaired private label securities had missed principal andor interest payments or had been downgraded by a NRSRO at March 31, 2022. The Company performed an analysis comparing the impairments were consideredpresent value of cash flows expected to be temporary.
Private label residentialMBSandCMOs
At September 30, 2017, five private label residential MBScollected to the amortized cost basis of impaired securities. This analysis was based on a scenario that we believe to be generally more conservative than our reasonable and CMOs were in unrealized loss positions, primarily as a result of an increase in mediumsupportable economic forecast at March 31, 2022, and long-term market interest rates subsequent to acquisition. The amount of impairment of each of the individual securities was less than 3% of amortized cost. These securities were assessed for OTTI using credit and prepayment behavioral models that incorporate CUSIP level constant default rates,incorporated assumptions about voluntary prepayment rates, and losscollateral defaults, delinquencies, severity and delinquency assumptions. The resultsother relevant factors as described further below. Our analysis also considered the structural characteristics of these assessments were not indicativeeach security and the level of credit losses related to any of these securities as of September 30, 2017. Given the limited severity of impairment and the expectation of timely recovery of outstanding principal, the impairments were considered to be temporary.

Credit quality information
Loans other than ACIindicators for residential loans are considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due, according to the contractual terms of the loan agreements. Commercial relationships on non-accrual status with committed balances greater than or equal to $1.0 million that have internal risk ratings of substandard or doubtful, as well as loans that have been modified in TDRs, are individually evaluated for impairment. Other commercial relationships on non-accrual status with committed balances under $1.0 million may also be evaluated individually for impairment, at management's discretion. The likelihood of loss related to loans assigned internal risk ratings of substandard or doubtful is considered elevated due to their identified credit weaknesses. Factors considered by management in evaluating impairment include payment status, financial condition of the borrower, collateral value, and other factors impacting the probability of collecting scheduled principal and interest payments when due.
ACI loans or pools are considered to be impaired when it is probable that the Company will be unable to collect all of the expected cash flows at acquisition (as adjusted for any additional cash flows expected to be collected arising from changes in estimates after acquisition), other than due to changes in interest rate indices and prepayment assumptions.

Non-covered loans contractually delinquent by 90 days or more and still accruing totaled $0.8 million and $1.6 million at September 30, 2017 and December 31, 2016, respectively. The amount of additional interest income that would have been recognized on non-accrual loans had they performed in accordance with their contractual terms was approximately $1.4 million and $3.7 million for the three and nine months ended September 30, 2017, respectively, and $1.1 million and $2.3 million for the three and nine months ended September 30, 2016, respectively.
Management considers delinquency status to be the most meaningful indicator of the credit quality of 1-4 single family residential home equity and other consumer loans, other than government insured residential loans. Delinquency statistics are updated at least monthly. See "Aging of loans" below for more information on the delinquency status of loans. Original LTV and original FICO scorescores are also important indicators of credit quality for the non-covered 1-4 single family residential portfolio. loans other than government insured loans. FICO scores are generally updated at least annually, and were most recently updated in the first quarter of 2022. LTVs are typically at origination since we do not routinely update residential appraisals. Substantially all of the government insured residential loans are government insured buyout loans, which the Company buys out of GNMA securitizations upon default. For these loans, traditional measures of credit quality are not particularly relevant considering the guaranteed nature of the loans and the underlying business model. Factors that impact risk inherent in the residential portfolio segment include national and regional economic conditions such as levels of unemployment and wages, as well as residential property values.

Credit quality indicators for commercial loans
Factors that impact risk inherent in commercial portfolio segments include but are not limited to levels of economic activity, health of the national and regional economy, industry trends, patterns of and trends in customer behavior that influence demand for our borrowers' products and services, and commercial real estate values. Internal risk ratings are considered the most meaningful indicator of credit quality for commercial loans. Internal risk ratings are generally indicative of the likelihood that a borrower will default, are a key factor in identifyinginfluencing the level and nature of ongoing monitoring of loans that are individually evaluated for impairment and may impact management’s estimates of loss factors used in determining the amountestimation of the ALLL.ACL. Internal risk ratings are updated on a continuous basis. Generally, relationships with balances in excess of defined thresholds, ranging from $1 million to $3 million, are re-evaluated at least annually and more frequently if circumstances indicate that a change in risk rating may be warranted. Loans exhibiting potential credit weaknesses that deserve management’s close attention and that if left uncorrected maycould result in deterioration of the repayment capacity of the borrowerprospects at some future date if not checked or corrected are categorized as special mention. Loans with well-defined credit weaknesses, including payment defaults, declining collateral values, frequent overdrafts, operating losses, increasing balance sheet leverage, inadequate cash flow from current operations, project cost overruns, unreasonable construction delays, past due real estate taxes or exhausted interest reserves, are assigned an internal risk rating of substandard. A loan with a weakness so severe that collection in full is highly questionable or improbable, but because of certain reasonably specific pending factors has not been charged off, will be assigned an internal risk rating of doubtful.

Note 5    FDIC Indemnification Asset
When the Company recognizes gains or losses related to covered assets in its consolidated financial statements, changes in the estimated amount recoverable from the FDIC under the Loss Sharing Agreements with respect to those gains or losses are also reflected in the consolidated financial statements. Covered loans may be resolved through prepayment, short sale of the underlying collateral, foreclosure, sale of the loans or charge-off. For loans resolved through prepayment, short sale or foreclosure, the difference between consideration received in satisfaction of the loans and the carrying value of the loans is recognized in the consolidated statement of income line item “Income from resolution of covered assets, net.” Losses from the resolution of covered loans increase the amount recoverable from the FDIC under the Loss Sharing Agreements. Gains from the resolution of covered loans reduce the amount recoverable from the FDIC under the Loss Sharing Agreements. Similarly, differences in proceeds received on the sale of covered OREO and covered loans and their carrying amounts result in gains or losses and reduce or increase the amount recoverable from the FDIC under the Loss Sharing Agreements. Increases in valuation allowances or impairment charges related to covered assets also increase the amount estimated to be recoverable from the FDIC. These additions to or reductions in amounts recoverable from the FDIC related to transactions in the covered assets are recorded in the consolidated statement of income line item “Net gain (loss) on FDIC indemnification” and reflected as corresponding increases or decreases in the FDIC indemnification asset.
In addition, through June 30, 2017, recoveries of previously indemnified losses on assets that were formerly covered under the Commercial Shared-Loss Agreement resulted in reimbursements due to the FDIC. These transactions are included in the tables below. Amounts payable to the FDIC resulting from these transactions are recognized in other liabilities in the accompanying consolidated balance sheet at December 31, 2016.
The following tables summarize the components of the gains and losses associated with covered assets, along with the related additions to or reductions in the amounts recoverable from the FDIC under the Loss Sharing Agreements, as reflected in the consolidated statements of income for the periods indicated (in thousands):

Note 6Income Taxes
The Company’s effective income tax rate was 32.2%24.4% and 31.7%24.7% for the three months ended September 30, 2017March 31, 2022 and 2016, respectively, and 31.2% and 33.2% for the nine months ended September 30, 2017 and 2016,2021, respectively. The effective income tax raterates differed from the statutory federal income tax rate of 35% in all periods21% due primarily to the effectimpact of state income taxes, partially offset by the benefit of income not subject to tax, offset by state income taxes. In addition, the effective income tax rate for the three and nine months ended September 30, 2017 reflected the impact of $0.3 million and $3.2 million, respectively, in excess tax benefits resulting from activity related to vesting of share-based awards and exercise of stock options.federal tax.
The Company has investments in affordable housing limited partnerships which generate federal Low Income Housing Tax Credits and other tax benefits. The balance of these investments, included in other assets in the accompanying consolidated balance sheet, was $66 million and $71 million at September 30, 2017 and December 31, 2016, respectively. Unfunded commitments for affordable housing investments, included in other liabilities in the accompanying consolidated balance sheet, were $29 million and $53 million at September 30, 2017 and December 31, 2016, respectively. The maximum exposure to loss as a result of the Company's involvement with these limited partnerships at September 30, 2017 was approximately $73 million. While the Company believes the likelihood of potential losses from these investments is remote, the maximum exposure was determined by assuming a scenario where the projects completely fail and do not meet certain government compliance requirements resulting in recapture of the related tax credits. These investments did not have a material impact on income tax expense for the three and nine months ended September 30, 2017 and 2016.

rate.
The Company also 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. TheFor the three months ended March 31, 2022 and 2021, the impact on earnings related to changes in fair value of these derivatives for the three and nine months ended September 30, 2017 and 2016 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

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 entered into with borrowers not subject to master netting agreements.
At September 30, 2017, the Company had pledged investment securities available for sale with a carrying amount of $40 million and cash on deposit of $2 million as collateral for interest rate swaps in a liability position. $2 million of financial collateral was pledged by counterparties to the Company for interest rate swaps in an asset position. 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.

Share Awards
Unvested share awards
DuringIn May 2022, the nine months ended September 30, 2017,Company's Board of Directors authorized the Company granted 618,306 unvested share awardsrepurchase of up to an additional $150 million in shares of its outstanding common stock. Any repurchases under the 2014 Plan. Allprogram will be made in accordance with applicable securities laws from time to time in open market or private transactions. No time limit was set for the completion of the shares vest in equal annual installments over a period of three years fromshare repurchase program, and the date of grant. The shares granted were valued at the closing price of the Company’s common stock on the date of grant, ranging from $33.21 to $40.84, and had an aggregate fair value of $24.9 million. The total unrecognized compensation cost of $26.7 million for all unvested share awards outstanding at September 30, 2017 will be recognized over a weighted average remaining period of 1.98 years.
During the nine months ended September 30, 2016, the Company granted 644,888 unvested share awards under the 2014 Plan. All of the shares vest in equal annual installments over a period of three years from the date of grant. The shares granted were valued at the closing price of the Company’s common stock on the date of grant, ranging from $29.78 to $33.76, and had an aggregate fair value of $20.0 million.
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 vest in equal tranches over three years. PSUs are initially granted based on a target value. The number of PSUs that ultimately vest at the end of a three-year performance measurement period will be based on the achievement of performance criteria pre-established by the Compensation Committee of the Board of Directors. The performance criteria established for the PSUs granted in 2017 and 2016 include both performance and market conditions. Upon vesting, the share units will be converted to common stock on a one-for-one basis, orprogram may be settled in cashsuspended or discontinued without prior notice 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.
The first tranche of RSUs granted vested on December 31, 2016. The Company cash settled these share units in the amount of $0.8 million during the first quarter of 2017. As a result of this cash settlement, all RSUs and PSUs have been determined to be liability instruments and will be 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 probability of meeting the defined performance conditions. Compensation cost related to PSUs is recognized during the performance period based on the probable outcome of the respective performance conditions.
During the nine months ended September 30, 2017, 47,848 RSUs and 47,848 PSUs were granted. During the nine months ended September 30, 2016, 57,873 RSUs and 57,873 PSUs were granted. The total liability for the share units was $2.6 million at September 30, 2017. The total unrecognized compensation cost of $5.3 million for these share units at September 30, 2017 will be recognized over a weighted average remaining period of 2.18 years.

The 618,306 unvested share awards granted during the nine months ended September 30, 2017, as discussed above, included 25,321 unvested share awards granted to certain of the Company's executives based on the achievement of performance criteria pre-established by the Compensation Committee for the year ended December 31, 2016.
Incentiveawards
Beginning in 2017, the Company's annual incentive compensation arrangements 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. The awards vest in equal installments over a period of three years from the date of grant. The total liability for the incentive share awards was $1.2 million at September 30, 2017. The total unrecognized compensation cost of $5.3 million for these share awards at September 30, 2017 will be recognized over a weighted average remaining period of 3.25 years. 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.

Note 108    Fair Value Measurements
Assets and liabilities measured at fair value on a recurring basis
FollowingThe 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, corporate debt securities, non-mortgage asset-backed securities, single family rental real estate-backed securities, certain 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. Investment securities available for sale generally classified within level 3 of the fair value hierarchy include certain private label MBS and trust preferred securities. The Company typically values these securities using third-party proprietary pricing models, primarily discounted cash flow valuation techniques, which incorporate both observable and unobservable inputs. Unobservable inputs that may impact the valuation of

BANKUNITED, INC. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - UNAUDITED
September 30, 2017


these securities include risk adjusted discount rates, projected prepayment rates, projected default rates and projected loss severity.
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. Fair value of residential MSRs is estimated using a discounted cash flow technique that incorporates market‑based assumptions including estimated prepayment speeds, contractual servicing fees, cost to service, discount rates, escrow account earnings, ancillary income, and estimated defaults. DueAs all significant inputs to the naturevaluation process are observable, these instruments are classified within level 2 of the valuation inputs and the limited availability of market pricing, servicing rights are classified as level 3.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 LIBORbenchmark swap rates and LIBORbenchmark forward yield curves. These fair value measurements are generally classified within level 2 of the fair value hierarchy.

Gains on private label residential MBS recognized in net income during the three and nine months ended September 30, 2017 are included in the consolidated statement of income line item "Gain on investment securities available for sale, net." Changes in the fair value of servicing rights are included in the consolidated statement of income line item “Other non-interest income.” Changes in fair value include changes due to valuation assumptions, primarily discount rates and prepayment speeds, as well as other changes such as runoff and the passage of time. The amount of net unrealized losses included in earnings for the nine months ended September 30, 2017 and 2016 that were related to servicing rights held at September 30, 2017 and 2016 totaled approximately $0.8 million and $1.7 million, respectively, and were primarily due to changes in discount rates and prepayment speeds.
Securities for which fair value measurements are categorized in level 3 of the fair value hierarchy at September 30, 2017 consisted of pooled trust preferred securities with a fair value of $5 million and private label residential MBS and CMOs with a fair value of $61 million. The trust preferred securities are not material to the Company’s financial statements. Private label residential MBS consisted of senior and mezzanine tranches collateralized by prime fixed rate and hybrid 1-4 single family residential mortgages originated before 2005, some of which contain option-arm features. Substantially all of these securities have variable rate coupons. Weighted average subordination levels at September 30, 2017 were 16.4% and 10.4% for investment grade and non-investment grade securities, respectively.
The following table provides information about the valuation techniques and unobservable inputs used in the valuation of private label residential MBS and CMOs falling within level 3 of the fair value hierarchy as of September 30, 2017 (dollars in thousands):

      Discount rate 1.35% - 9.43% (5.89%)
The significant unobservable inputs impacting the fair value measurement of private label residential MBS and CMOs include voluntary prepayment rates, probability of default, loss severity given default and discount rates. Generally, increases in

probability of default, loss severity or discount rates would result in a lower fair value measurement. Alternatively, decreases in probability of default, loss severity or discount rates would result in a higher fair value measurement. For securities with less favorable credit characteristics, decreases in voluntary prepayment speeds may be interpreted as a deterioration in the overall credit quality of the underlying collateral and as such, lead to lower fair value measurements. The fair value measurements of those securities with higher levels of subordination will be less sensitive to changes in these unobservable inputs other than discount rates, while securities with lower levels of subordination will show a higher degree of sensitivity to changes in these unobservable inputs other than discount rates. Generally, a change in the assumption used for probability of default is accompanied by a directionally similar change in the assumption used for loss severity given default and a directionally opposite change in the assumption used for voluntary prepayment rate. 
The following table provides information about the valuation techniques and significant unobservable inputs used in the valuation of servicing rights as of September 30, 2017 (dollars in thousands):
  Fair Value at Valuation Technique

      Discount rate 9.50% - 9.58% (9.51%)
         
Commercial servicing rights $12,130
 Discounted cash flow Prepayment rate 0.09% - 9.99% (7.81%)
      Discount rate 8.12% - 14.57% (12.48%)
Increases in prepayment rates or discount rates would result in lower fair value measurements and decreases in prepayment rates or discount rates would result in higher fair value measurements. Although the prepayment rate and the discount rate are not directly interrelated, they generally move in opposite directions.
Assets and liabilities measured at fair value on a non-recurring basisbasis
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. 
ImpairedCollateral dependent loans OREOand other repossessed assetsOREO—The carrying amount of collateral dependent impaired loans is typically based on the fair value of the underlying collateral, which may be real estate taxi medallions, or other business assets, less estimated costs to sell.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. When current appraisals are not available, the Company may use brokers’ price opinions, home price indices or other available information about changes in real estate market conditions to adjust the latest appraised value available. These adjustments to appraised values may be subjective and involve significant management judgment. The fair value of repossessed assets, other than taxi medallions, or collateral consisting of other business assets may be based on third-party appraisals or internal analyses that use market approaches to valuation incorporating primarily unobservable inputs.
The fair value of New York City taxi medallions is based primarily on an internal analysis that utilizes an income approach to valuation. This analysis utilizes data obtained from the NYTLC about the fleet in general and in some cases, our portfolio specifically, and management's assumptions, based on external data when available, about revenues, costs and expenses, to estimate the value that can reasonably be supported by the cash flow generating capacity of a medallion. We further discount the results of this analysis in recognition of estimated selling costs and declining trends in medallion values. We also consider prices of recent medallion transfers as published by the NYTLC; however, the market for taxi medallions is illiquid and information about the circumstances underlying observed transfers is unavailable, therefore, information about recent transfers is not considered sufficient to establish a reliable estimate of value. The Company's medallion valuations fall within the range of published transfer prices over the last six months. Taxi medallions in municipalities other than New York City are generally valued based on published information about recent transfer prices; the valuation of these assets did not have a material impact on the Company's consolidated financial statements for any period presented as the taxi medallion portfolio is heavily concentrated in New York City.

The following methods and assumptions were used to estimate the fair value of each class of financial instruments, other than those described above:
Cash and cash equivalents
The carrying value of cash and cash equivalents approximates fair value due to their short-term nature and generally negligible credit risk.
Investment securities held to maturity
Investment securities held to maturity includes one bond issued by the State of Israel, with fair value obtained from a third party pricing service.
Non-marketable equity securities
Non-marketable equity securities include FHLB and FRB stock. There is no market for these securities, which can be liquidated only by redemption by the issuer. These securities are valued at par, which has historically represented the redemption price and is therefore considered to approximate fair value.
Loans held for sale
The fair value of the portion of small business loans guaranteed by U.S. Government agencies being held for sale is estimated using pricing on recent sales of similar loans by the Company in active markets.

Covered loans
Fair values are estimated based on a discounted cash flow analysis. Estimates of future cash flows incorporate various factors that may include the type of loan and related collateral, estimated collateral values, estimated voluntary prepayment rates, estimated default probability and loss severity given default, whether the interest rate is fixed or variable, term of loan and whether or not the loan is amortizing. The fair values of loans accounted for in pools are estimated on a pool basis. Discount rates for residential loans are based on observable fixed income market data for products with similar credit characteristics.
Non-covered loans
Fair values of residential loans are estimated using a discounted cash flow analysis with discount rates based on yields at which similar loans are trading in the secondary market, which reflect assumptions about credit risk. Fair values of commercial and consumer loans are estimated using a discounted cash flow analysis with discount rates based on interest rates currently being offered for loans with similar terms to borrowers of similar credit quality. The ALLL related to commercial and consumer loans is considered a reasonable estimate of the required adjustment to fair value to reflect the impact of credit risk. This estimate may not represent an exit value as defined in ASC 820.
FDIC indemnification asset
The fair value of the FDIC indemnification asset has been estimated using a discounted cash flow technique incorporating assumptions about the timing and amount of future projected cash payments from the FDIC related to the resolution of covered assets. The factors that impact estimates of future cash flows are similar to those impacting estimated cash flows from covered loans. The discount rate is determined by adjusting the risk free rate to incorporate uncertainty in the estimate of the timing and amount of future cash flows and illiquidity.
Deposits
The fair value of demand deposits, savings accounts and money market deposits is the amount payable on demand at the reporting date. The fair value of time deposits is estimated using a discounted cash flow technique based on rates currently offered for deposits of similar remaining maturities.
FHLB advances
Fair value is estimated by discounting contractual future cash flows using the current rate at which borrowings with similar terms and remaining maturities could be obtained by the Company.
Senior notes
Fair value is estimated based on quoted prices of identical securities in less active markets.
Note 119    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. Unfunded commitments under lines of credit include $10.0 million available under non-cancellable commitments in effect at the date of the FSB Acquisition, which are covered under the Single Family Shared-Loss Agreement if prescribed conditions are met.
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 home equity and consumer lines of credit to existing customers.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.funded, so may not necessarily represent future liquidity requirements. 
Commercial and standby letters of credit
Letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. These letters of credit are primarily issued to support trade transactions or guarantee arrangements. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers.

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.

Overview
Quarterly Highlights
In evaluating our financial performance, we consider the level of and trends in net interest income, the net interest margin, the cost of deposits, levels and composition of non-interest income and non-interest expense, performance ratios such as the return on average equity and return on average assets and asset quality ratios, particularly for the non-covered portfolio, including the ratio of non-performing loans to total loans, non-performing assets to total assets, trends in criticized and classified assets and portfolio delinquency and charge-off trends. We consider growth in and the composition of earning assets and deposits, trends in funding mix and cost of funds. We analyze these ratios and trends against our own historical performance, our budgeted performance and the financial condition and performance of comparable financial institutions.
Quarterly highlights include:
Net income for the quarterthree months ended September 30, 2017March 31, 2022 was $67.8$67.2 million, or $0.62$0.79 per diluted share, compared to $50.8$98.8 million, or $0.47$1.06 per diluted share, for the quarter ended September 30, 2016. For the ninethree months ended September 30, 2017, net income was $196.5March 31, 2021 and $125.3 million, or $1.79 per diluted share, compared to $162.4 million, or $1.50$1.41 per diluted share for the nineimmediately preceding three months ended September 30, 2016.December 31, 2021. As previously reported, earnings for the quarter ended December 31, 2021 were impacted by discrete income tax benefits of $69.1 million and a $44.8 million pre-tax loss on discontinuance of hedges. Earnings for the ninequarter ended March 31, 2021 were favorably impacted by a $28.0 million recovery of the provision for credit losses. For the three months ended September 30, 2017 generated anMarch 31, 2022, the annualized return on average stockholders' equity of 10.21%was 9.0% and anthe annualized return on average assets of 0.92%was 0.76%.
Net interest income increased by $19.5 million to $241.3 million for the quarter ended September 30, 2017 from $221.7 million for the quarter ended September 30, 2016. Interest income increased by $39.5 million, driven by increases in the average balances of loans and investment securities outstanding and an increase in the yield on interest earning assets. Interest expense increased by $19.9 million, driven by increases in average interest bearing liabilities and the cost of those liabilities. For the nine months ended September 30, 2017, net interest income increased by $68.6 million to $711.4 million from $642.9 million for the nine months ended September 30, 2016.
The net interest margin, calculated on a tax-equivalent basis, decreasedexpanded to 3.62%2.50% for the quarterthree months ended September 30, 2017March 31, 2022 from 3.69% for the quarter ended September 30, 2016 and 3.76%2.44% for the immediately preceding quarterthree months and 2.39% for the three months ended June 30, 2017. Significant factors contributingMarch 31, 2021.

Hurricanes Irma and Harvey
On September 10, 2017, Hurricane Irma made landfall in Florida as a Category 4 hurricane affecting some areas of the state with significant flooding, wind damage and power outages. In addition, the Bank has a limited number of customers and collateral properties located in areas of Texas that were impacted by Hurricane Harvey during August, 2017.
Loan and Lease Portfolio
The Company has assessed the potential impactannounced an increase of the hurricanes on the value of collateral underlying our loans and the ability of borrowers to repay their obligations to the Bank. We believe the storms did not materially impact the ability of the substantial majority of our borrowers to repay their loans; however, uncertainty remains as to the ultimate impact of these events on the level of our loan losses and our results of operations.
In order to assess the impact of these hurricanes on our loan and lease portfolio, the Company performed an extensive review of loans with borrowers and/or collateral located$0.02 in areas impacted by these storms. This analysis entailed the identification of and direct communication with borrowers located in impacted areas to determine the population of borrowers that may have been significantly impacted as well as consideration of factors including but not limited to level and type of insurance coverage, collateral and lien position and the financial condition of the borrower.
Commercial and commercial real estate loans with an aggregate UPB of approximately $7.1 billion at September 30, 2017 were determined to be either made to borrowers that have significant business operations in or secured by collateral in areas that were potentially impacted by the hurricanes. Substantially all of those borrowers had been contacted as of October 3, 2017 and responses were considered in the determination of the ALLL as of September 30, 2017. As of October 31, 2017, commercial loans with an aggregate UPB of $22.2 million had been downgraded to criticized or classified status as a result of this analysis. Residential mortgage and other consumer loans with a carrying value of approximately $977 million at September 30, 2017, of which $315 million are covered loans, were determined to be either made to borrowers living in or secured by collateral in areas potentially impacted by the hurricanes; such loans with a carrying value of approximately $902 million, of which $312 million are covered loans, were determined to be in severely impacted areas, based on FEMA’s designation as “individual assistance” areas (“FEMA designated areas”). As of October 31, 2017, 74% of borrowers in FEMA designated areas had been contacted or property inspections conducted to assist in assessing the extent of potential damage to underlying collateral. During the quarter ended September 30, 2017, the Company recorded a loan loss provision of $5.4 million related to the impact of Hurricanes Irma and Harvey.

Impairment of Other Assets
Management also considered the impact of the hurricanes in our analysis of investment securities for OTTI, as well as our evaluation of potential impairment of our investment in equipment under operating lease, LIHTC partnerships, servicing assets and OREO at September 30, 2017 and determined there was no potentially material impact.
Fees, Operations and Facilities
To help those affected by Hurricane Irma, the Company waived or refunded certain fees such as overdraft, NSF and uncollected fees on consumer deposit accounts and late fees on residential mortgage, consumer and small business loans for consumer and small business customers in FEMA designated disaster areasits cash dividend for the period September 10, 2017 through September 30, 2017. In addition, certain residential mortgage and SBA loan customers impacted bythree months ended March 31, 2022 to $0.25 per common share, reflecting a 9% increase from the storm may be eligible for assistance in the formprevious quarterly dividend of temporary payment deferrals. Waived and refunded fees were not significant.$0.23 per common share.
The Company’s operations and facilities were not materially impacted by Hurricane Irma. The Company continued operating throughout the storm although all of our Florida branch locations were closed from September 8, 2017 through September 11, 2017. The majority of our Florida branch locations and our Miami Lakes corporate headquarters re-opened on September 12, 2017 and all of our Florida branch locations re-opened prior to September 30, 2017.
During the quarter ended September 30, 2017, the Company recorded expenses of $0.6 million related primarily to facilities damage and employee relocation and assistance. We do not expect future expenses related to facilities damage to be material to the Company.
Community Assistance
To help with the recovery efforts of the communities in which we operate, work and live, BankUnited has made donations totaling $100,000 to non-profit organizations focused on recovery and relief efforts in Florida. These organizations were selected based on their ability to immediately deploy resources directly to targeted affected areas.
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 relative 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, and by management's continual assessment of the rate of return and relative risk associated with various classes of earning assets.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 requirementsexpectations, our ability to attract and is impacted byretain core deposit relationships, competition for deposits in the Company's markets and the availability and pricing of other sources of funds.
Net interest income is also impacted by the accounting for ACI loans acquired in conjunction with the FSB Acquisition. ACI loans were initially recorded at fair value, measured based on the present value of expected cash flows. The excess of expected cash flows over carrying value, known as accretable yield, is recognized as interest income over the lives of the underlying loans. The positive impact of accretion related to ACI loans on the net interest margin and the interest rate spread is expected to continue to decline as ACI loans comprise a declining percentage of total loans. The proportion of total loans represented by ACI loans is declining as the ACI loans are resolved and new loans are added to the portfolio. ACI loans represented 2.5% and 3.0% of total loans, including premiums, discounts and deferred fees and costs, at September 30, 2017 and December 31, 2016, respectively. As this trend continues, assuming an otherwise stable interest rate environment, we would expect our net interest margin and interest rate spread to decrease as covered loans are resolved.

The impact of ACI loan accounting on net interest income makes it difficult to compare our net interest margin and interest rate spread to those reported by other financial institutions.



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 and restructured 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 35.0%21% (dollars in thousands):

Three months ended September 30, 2017March 31, 2022 compared to the immediately preceding three months ended September 30, 2016December 31, 2021
Net interest income, calculated on a tax-equivalent basis, was $252.0$212.3 million for the three months ended March 31, 2022, compared to $209.8 million for the three months ended September 30, 2017December 31, 2021, an increase of $2.5 million. The increase in net interest income was comprised of decreases in tax-equivalent interest income and interest expense of $2.0 million and $4.5 million, respectively, for the three months ended March 31, 2022, compared to $230.5the three months ended December 31, 2021. The decrease in interest income reflected a lower yield on average loans and lower day count, partially offset by a higher average balance of loans and higher yield on investment securities. The decrease in interest expense reflected a lower cost of both interest bearing deposits and FHLB advances and lower day count, partially offset by a higher average balance of interest-bearing liabilities, particularly FHLB advances.

The net interest margin, calculated on a tax-equivalent basis, was 2.50% for the three months ended March 31, 2022, compared to 2.44% for the three months ended December 31, 2021. Offsetting factors impacting the net interest margin for the three months ended March 31, 2022 compared to the immediately preceding three months ended December 31, 2021 included:
The tax-equivalent yield on investment securities increased to 1.73%, for the three months ended March 31, 2022 from 1.54%for the three months ended December 31, 2021. This increase resulted from the impact of purchases of higher-yielding securities and slower prepayment speeds on securities purchased at a premium.
The tax-equivalent yield on loans decreased to 3.36% for the three months ended March 31, 2022, from 3.50% for the three months ended December 31, 2021. Factors contributing to this decrease included runoff of loans originated in a comparatively higher rate environment, slower prepayment speeds on PCD residential loans, the effect of the sale of a pool of higher yielding residential loans during the fourth quarter of 2021, lower prepayment penalties and partially offsetting higher PPP fee recognition.
The average rate paid on FHLB advances decreased to 1.11% for the three months ended March 31, 2022 from 1.86% for the three months ended December 31, 2021. This decrease resulted from the maturity of higher rate advances, including the termination of certain cash flow hedges during the three months ended December 31, 2021, and the addition of new advances at comparatively lower prevailing rates.
The average rate paid on interest bearing deposits decreased to 0.24% for the three months ended March 31, 2022, from 0.27% for the three months ended December 31, 2021. Callable and other brokered CDs and cash flow hedges entered into in anticipation of rising rates impacted the cost of deposits for the quarter; the average rate paid on interest bearing deposits excluding these instruments was 0.21% for the quarter ended March 31, 2022. The increase in the average cost of time deposits for the quarter ended March 31, 2022 compared to the quarter ended December 31, 2021 was attributable to these products. The average cost of time deposits other than these products was 0.22% for the quarter ended March 31, 2022.

Net interest income, calculated on a tax-equivalent basis, was $212.3 million for the three months ended March 31, 2022, compared to $200.4 million for the three months ended September 30, 2016,March 31, 2021, an increase of $21.5$11.9 million. The increase in net interest income was comprised of an increasedecreases in tax-equivalent interest income and interest expense of $41.5$10.0 million and $21.9 million, respectively, for the three months ended March 31, 2022, compared to the three months ended March 31, 2021. The decrease in interest income related to lower interest income on loans, resulting primarily from the turnover of the loan portfolio at lower prevailing rates, partially offset by an increase in interest expense of $19.9 million.
The increase in tax-equivalent interest income was comprised primarily of a $27.9 million increase in interest income from loans and a $12.8 million increase in interest income fromon investment securities.

Increased interest income from loans was attributablesecurities related to a $1.7 billionan increase in the average balance outstanding and a 0.12% increase in the tax-equivalent yield to 5.15% for the three months ended September 30, 2017 from 5.03% for the three months ended September 30, 2016. Factors contributing to the increase in the yield on loans included:
balance. The tax-equivalent yield on non-covered loans was 3.79% for the three months ended September 30, 2017 compared to 3.56% for the three months ended September 30, 2016. The most significant factor contributing to the increased yield on non-covered loans was increases in market interest rates.
Interest income on covered loans totaled $73.5 million and $74.5 million for the three months ended September 30, 2017 and 2016, respectively. The tax-equivalent yield on those loans increased to 56.70% for the three months ended September 30, 2017 from 42.50% for the three months ended September 30, 2016. The increase in the yield on covered loans resulted primarily from improvements in expected cash flows for ACI loans.
The impact on the overall yield on loans of increased yields on both covered and non-covered loans considered individually was somewhat offset by the continued increase in non-covered loans, with yields lower than those on covered loans, as a percentage of total loans.
The average balance of investment securities increased by $1.1 billion for the three months ended September 30, 2017 from the three months ended September 30, 2016 while the tax-equivalent yield increased to 3.14% from 2.87%. The most significant factor contributing to the increase in the tax-equivalent yield were increases in coupon rates on floating-rate securities.

Provision for Credit Losses
The provision for credit losses is a charge or credit to earnings required to maintain the ACL at a level consistent with management’s estimate of expected credit losses on financial assets carried at amortized cost at the balance sheet date. The

amount of the provision is impacted by changes in market interest rates, includingcurrent economic conditions, as well as in management's reasonable and supportable economic forecast, loan originations and runoff, changes in portfolio mix, risk rating migration and portfolio seasoning, changes in specific reserves, changes in expected prepayment speeds and other assumptions. The provision for credit losses also includes amounts related to off-balance sheet credit exposures and may include amounts related to accrued interest receivable and AFS debt securities.

Ninethree months ended September 30, 2017 compared to nine months ended September 30, 2016
Net interest income, calculated on a tax-equivalent basis,March 31, 2022 was $742.7 million for the nine months ended September 30, 2017 compared to $667.1 million for the nine months ended September 30, 2016, an increase of $75.5 million. The increase in net interest income was comprised of an increase in tax-equivalent interest income of $117.6 million, offsetimpacted by an increase in interest expense of $42.0 million.
The increase in tax-equivalent interest income was comprised primarily of an $81.9 million increase in interest income from loans and a $33.9 million increase in interest income from investment securities.
Increased interest income from loans was attributablequalitative loss factors related to a $2.1 billion increase in the average balance and a 0.01% increase in the tax-equivalent yield to 5.15% for the nine months ended September 30, 2017 from 5.14% for the nine months ended September 30, 2016. Offsetting factors contributingeconomic uncertainty. Those qualitative considerations included but were not necessarily limited to the relatively steady yield on loans included:
Although the yield on non-covered loans increasedFederal Reserve's plans for quantitative tightening and increasing its benchmark rate and geopolitical uncertainty, some of which have emerged or evolved subsequent to 3.73% for the nine months ended September 30, 2017 from 3.58% for the nine months ended September 30, 2016, lower-yielding non-covered loans comprised a greater percentagepublishing of the portfolio foreconomic scenarios used in developing the nine months ended September 30, 2017 than for the corresponding period in 2016. Non-covered loans represented 97.2%quantitative estimate of the average balanceACL. The recovery of loans outstanding for the nine months ended September 30, 2017 compared to 95.8% for the nine months ended September 30, 2016.

Interest income on covered loans totaled $225.2 million and $226.7 million for the nine months ended September 30, 2017 and 2016, respectively. The tax-equivalent yield on those loans increased to 53.54% for the nine months ended September 30, 2017 from 40.48% for the nine months ended September 30, 2016.
The average balance of investment securities increased by $1.0 billion for the nine months ended September 30, 2017 from the nine months ended September 30, 2016 while the tax-equivalent yield increased to 3.07% from 2.82%.
The components of the increase in interest expense for the nine months ended September 30, 2017 as compared to the nine months ended September 30, 2016 were a $33.7 million increase in interest expense on deposits and an $8.3 million increase in interest expense on FHLB advances.
The increase in interest expense on deposits was attributable to an increase of $2.4 billion in average interest bearing deposits and an increase in the average cost of interest bearing deposits of 0.16% to 0.94% for the nine months ended September 30, 2017 from 0.78% for the nine months ended September 30, 2016. The increase in interest expense on FHLB advances was primarily a result of an increase in the average cost of advances of 0.19% to 1.21% for the nine months ended September 30, 2017 from 1.02% for the nine months ended September 30, 2016.
Factors contributing to the changes in yields and costs for the nine month periods were generally consistent with thosecredit losses for the three month periods discussed above.
The net interest margin, calculated on a tax-equivalent basis, for the nine months ended September 30, 2017March 31, 2021 was 3.69% as compared to 3.75% for the nine months ended September 30, 2016. The interest rate spread decreased to 3.51% for the nine months ended September 30, 2017 from 3.60% for the nine months ended September 30, 2016. The declineslargely driven by improvements in net interest margin and interest rate spread resulted primarily from the factors discussed above.
Provision for Loan Lossesforecasted economic conditions.
The provision for loancredit losses ismay continue to be volatile and the amountlevel of expense that, based on our judgment, is required to maintain the ALLL at an adequate level to absorb probable losses inherentACL may change materially from current levels. Future levels of the ACL could be significantly impacted, in either direction, by changes in the loan portfolio ateconomic outlook and by the balance sheet dateevolving impact of the COVID-19 pandemic, geopolitical events, and that,their impact on individual borrowers in management’s judgment, is appropriate under GAAP. the portfolio.
The determination of the amount of the ALLLACL is complex and involves a high degree of judgment and subjectivity. Our determination of the amount of the allowance and corresponding provision for loan losses considers ongoing evaluations of the credit quality of and level of credit risk inherent in various segments of the loan portfolio and of individually significant credits, levels of non-performing loans and charge-offs, historical and statistical trends and economic and other relevant factors. See “Analysis of the Allowance for Loan and LeaseCredit Losses” below for more information about how we determine the appropriate level of the allowance.
The provision for loan losses forACL and about factors that impacted the quarter and nine months ended September 30, 2017 included $5.4 million related to the impact of Hurricanes Irma and Harvey. The amount of this provision was determined based on our evaluation of an intensive analysis conducted by our credit teams of the individual loans potentially impacted by these storms, including but not limited to direct contact with borrowers, preliminary assessments of the extent of damage to collateral and impacts on borrowers’ business operations and consideration of the impact of insurance coverage. The amount of the provision related to the impact of these storms is subject to change as individual situations evolve.
For the three months ended September 30, 2017 and 2016, we recorded provisions for loan losses of $37.6 million and $24.9 million, respectively, related to non-covered loans. For the nine months ended September 30, 2017 and 2016, we recorded provisions for loan losses of $60.9 million and $43.6 million, respectively, related to non-covered loans. The amount of the provision is impacted by loan growth, portfolio mix, historical loss rates, the level of charge-offs and specific reserves for impaired loans, and management's evaluation of qualitative factors in the determination of general reserves.
The most significant reason for the increase in the provision for loan losses related to non-covered loans for the quarter ended September 30, 2017 compared to the quarter ended September 30, 2016 was an increase of $28.9 million in the provision related to taxi medallion loans. The provision related to taxi medallion loans totaled $32.7 million for the quarter ended September 30, 2017, compared to $3.9 million for the quarter ended September 30, 2016. A $5.4 million provision recognized in the quarter ended September 30, 2017 related to the impact of hurricanes was more than offset by (i) a net decrease in the relative impact on the provision of changes in quantitative and qualitative loss factors, (ii) the impact of lower loan growth, and (iii) a decrease in provisions for criticized and classified loans.
Factors contributing to the increase in the provision for loan losses related to non-covered loans for the nine months ended September 30, 2017 as compared to the nine months ended September 30, 2016 were generally consistent with those for the three month periods discussed above.

For the three months ended September 30, 2017 and 2016, we recorded provisions for (recovery of) loan losses of $0.3 million and $(0.4) million, respectively, related to covered loans. For the nine months ended September 30, 2017 and 2016, we recorded provisions for (recovery of) loan losses of $2.7 million and $(1.1) million, respectively, related to covered loans. The provision for the nine months ended September 30, 2017 related primarily to impairment recognized on an ACI HELOC pool. As discussed below in the section entitled "Non-interest income," the impact on our results of operations of any provision for (recovery of) loan losses on covered loans is significantly mitigated by the corresponding impact on the FDIC indemnification asset, recorded in non-interest income.
Non-Interest Income
The Company reported non-interest income of $53.3 million and $25.1 millionACL for the three months ended September 30, 2017 and 2016, respectively. Non-interest income was $111.4 million and $77.1 million for the nine months ended September 30, 2017 and 2016, respectively. A significant portion of our non-interest income has historically related to transactions in the covered assets. We have broken out the significant categories of non-interest income that relate to covered assets in the table below, to assist in the comparison of the amount and composition of our non-interest income with that of other financial institutions.March 31, 2022.

The consolidated financial statements reflectunrealized loss on marketable equity securities for the impact of gains or losses arising from transactionsthree months ended March 31, 2022 was attributable to the decline in the covered assets. fair value of certain preferred stock investments resulting from rising market interest rates.
The balance of the FDIC indemnification asset is reduced or increased as a result of decreases or increases in cash flows expected to be received from the FDIC related to these gains or losses. When these transaction gains or losses are recorded, we also record an offsetting amount in the consolidated statement of income line item “Net gain (loss) on FDIC indemnification.” This line item includes the significantly mitigating impact of FDIC indemnification relatedmost significant factors leading to the following types of transactionsdecrease in covered assets:
gains or losses from the resolution of covered assets;
provisions for (recoveries of) losses on covered loans;
gains or losses on the sale of covered loans; and
gains or losses on covered OREO.
See Note 5 to the consolidated financial statements for further details about the components of these gains and losses associated with covered assets, along with the related additions to or reductions in the amounts recoverable from the FDIC under the Loss Sharing Agreements, as reflected in the consolidated statements ofother non-interest income for the three and nine months ended September 30, 2017 and 2016.
Covered loans may be resolved through prepayment, short sale of the underlying collateral, foreclosure, sale of the loans or charge-off. For loans resolved through prepayment, short sale or foreclosure, the difference between consideration received in resolution of the loans and the carrying value of the loans is recorded in the consolidated statement of income line item “Income

from resolution of covered assets, net.” Both gains and losses on individual resolutions are included in this line item. Losses from the resolution of covered loans increase the amount recoverable from the FDIC under the Loss Sharing Agreements. Gains from the resolution of covered loans reduce the amount recoverable from the FDIC under the Loss Sharing Agreements. These additionsMarch 31, 2022 compared to or reductions in amounts recoverable from the FDIC related to the resolution of covered loans are recorded in non-interest income in the line item “Net gain (loss) on FDIC indemnification” and reflected as corresponding increases or decreases in the FDIC indemnification asset. The amount of income or loss recorded in any period will be impacted by the amount of covered loans resolved, the amount of consideration received, and our ability to accurately project cash flows from ACI loans in future periods.

Under the terms of the Purchase and Assumption Agreement with the FDIC, the Bank may sell up to 2.5% of the covered loans based on UPB at the date of the FSB Acquisition, or approximately $280 million, on an annual basis without prior consent of the FDIC. Any losses incurred from such loan sales are covered under the Single Family Shared-Loss Agreement. Any loan sale in excess of this stipulated annual threshold requires approval from the FDIC to be eligible for loss share coverage. However, if the Bank seeks to sell covered loans in excess of the 2.5% threshold in the nine months prior to the stated termination date of loss share coverage, May 21, 2019, and the FDIC does not consent, the Single Family Shared-Loss Agreement will be extended for two additional years with respect to the loans requested to be included in such sales. The Bank will then have the right to sell all or any portion of such loans without FDIC consent at any time within the nine months prior to the extended termination date, and any losses incurred will be covered under the Single Family Shared-Loss Agreement. This final sale mechanism, if exercised, ensures no residual credit risk in our covered loan portfolio that would otherwise arise from credit losses occurring after the termination date of the Single Family Shared-Loss Agreement.

The Bank did not sell covered residential loans in the three months ended September 30, 2017, due to the potential impact of Hurricane Irma on the market for these loans, the collateral for many of which is located in Florida.
Pricing received on the sale of covered loans may vary based on (i) market conditions, including the interest rate environment, the amount of capital seeking investment and the secondary supply of loans with a particular performance history or collateral type, (ii) the type and quality of collateral, (iii) the performance history of loans included in the sale and (iv) whether or not the loans have been modified. We anticipate that we will continue to exercise our right to sell covered residential loans on a quarterly basis in the future.
Other components of non-interest income
Period over period increasesMarch 31, 2021 were declines in income from lease financing corresponded to the growth in the portfolio of equipment under operating lease.
Gains on sale of non-covered loans for the three and nine months ended September 30, 2017 and 2016 related primarily to sales of loans by SBF.

Gain on sale of investment securities available for sale, net totaled $26.9 million for the quarter ended September 30, 2017. Substantially all of these gains resulted from the sale of securities formerly covered under the Commercial Shared-Loss Agreement and originally acquired at significant discounts in the FSB Acquisition.

Employee compensation and benefits
As is typical for financial institutions, employee compensation and benefits represents the single largest component of recurring non-interest expense. Employee compensation and benefits increased by $7.8 million for the three months ended March 31, 2022 compared to the three months ended March 31, 2021. The increase was primarily due to increased headcount and employee compensation increases.
Deposit insurance expense
Deposit insurance expense decreased by $4.0 million for the three and nine months ended September 30, 2017 increased by $3.2 million and $12.0 millionMarch 31, 2022, compared to the corresponding periods in 2016. The increases for the three and nine months ended September 30, 2017March 31, 2021, primarily reflected increased headcount and general increases in compensation levels.
Amortization of FDIC indemnification asset
Amortization of FDIC indemnification asset totaled $45.2 million and $135.4 million, respectively, for the three and nine months ended September 30, 2017 compared to $39.0 million and $116.7 million, respectively, for the three and nine months ended September 30, 2016.
The FDIC indemnification asset was initially recorded at its estimated fair value, representing the present value of estimated future cash payments from the FDIC for probable losses on covered assets. As projected cash flows from the ACI loans have increased, the yield on the loans has increased accordingly and the estimated future cash payments from the FDIC have decreased. This change in estimated cash flows is recognized prospectively, consistent with the recognition of the increased cash flows from the ACI loans. Asas a result the FDIC indemnification asset is being amortized to the amount of the estimated future cash flows. For the three and nine months ended September 30, 2017, the average rate at which the FDIC indemnification asset was amortized was 46.62% and 41.19%, respectively, compared to 25.36% and 23.48%, respectively, during the comparable periods in 2016.
The rate of amortization will increase if estimated future cash payments from the FDIC decrease. The amount of amortization is impacted by both the changean improvement in the amortization rate and the decrease in the average balance of the indemnification asset. As we continue to submit claims under the Loss Sharing Agreements and recognize periodic amortization, the balance of the indemnification asset will continue to decline.assessment rate.

See Note 5 to the consolidated financial statements for a rollforward of the FDIC indemnification asset for the nine months ended September 30, 2017 and the year ended December 31, 2016. The entire balance of the FDIC indemnification asset relatesinformation about income taxes.

to residential loans and OREO covered under the Single Family Shared-Loss Agreement. The following table presents the carrying value of the FDIC indemnification asset and the estimated future cash flows at the dates indicated (in thousands):
 September 30, 2017 December 31, 2016
FDIC indemnification asset$349,617
 $515,933
Less expected amortization(173,685) (245,350)
Amount expected to be collected from the FDIC$175,932
 $270,583
The amount of expected amortization reflects the impact of improvements in cash flows expected to be collected from the covered loans, as well as the impact of time value resulting from the discounting of the asset when it was initially established. This amount will be amortized to non-interest expense using the effective interest method over the period during which cash flows from the FDIC are expected to be collected, which is limited to the lesser of the contractual term of the Single Family Shared-Loss Agreement and the expected remaining life of the indemnified assets.
Deposit insurance expense
Deposit insurance expense increased $0.8 million and $4.0 million, respectively, for the three and nine months ended September 30, 2017 compared to the corresponding periods in 2016. These increases primarily reflect the growth of the balance sheet, the large bank surcharge imposed by the FDIC, which began in the third quarter of 2016, and increases in certain components of the Bank's assessment rate.
Depreciation of equipment under operating lease
Depreciation of equipment under operating lease increased by $2.1 million and $5.7 million, respectively, for the three and nine months ended September 30, 2017 compared to the corresponding periods in 2016. These increases generally correspond to the growth in the portfolio of equipment under operating lease.
Other non-interest expense
The most significant components of other non-interest expense are advertising and promotion, costs related to lending activities and deposit generation, OREO related expenses, insurance, travel and general office expense. Other non-interest expense for the three months ended September 30, 2017 includes $0.6 million related primarily to facilities damage and employee relocation and assistance due to the impact of Hurricane Irma. We do not expect future expenses related to facilities damage and employee relocation to be material to the Company.
Income Taxes
The Company’s effective income tax rate was 32.2% and 31.2% for the three and nine months ended September 30, 2017, respectively, compared to 31.7% and 33.2% for the three and nine months ended September 30, 2016, respectively. Significant components included in the reconciliation of the Company's effective income tax rate to the statutory federal tax rate of 35.0% included the effect of state income taxes and the impact of income not subject to federal tax for each of the periods presented. In addition, the effective income tax rate for the three and nine months ended September 30, 2017 reflected the impact of $0.3 million and $3.2 million, respectively, in excess tax benefits resulting from activity related to vesting of share-based awards and exercise of stock options.
Analysis of Financial Condition
Average interest-earning assets increased $3.2 billionby $425 million to $26.9$34.1 billion for the ninethree months ended September 30, 2017March 31, 2022 from $23.7$33.7 billion for the ninethree months ended September 30, 2016. This increase was driven by a $2.1 billion increase in the average balance of outstanding loans and a $1.0 billionMarch 31, 2021, primarily due to an increase in the average balance of investment securities. The increase in average loans reflected growth of $2.3 billion in average non-covered loans outstanding, partially offset by a $186 million decrease in the average balance of covered loans. The decrease in average non-interest earning assets period over period primarily reflected a decrease in the FDIC indemnification asset. Growth in interest earning assets, resolution of covered loans and declines in the amount of the FDIC indemnification asset are trends that are expected to continue.
Average interest bearing liabilities increased $2.6 billion to $22.4 billiondeclined by $912.9 million for the ninethree months ended September 30, 2017 from $19.8 billion forMarch 31, 2022 compared to the ninethree months ended September 30, 2016, due to increases of $2.4 billionMarch 31, 2021, reflecting declines in both average interest bearinginterest-bearing deposits and $191 million in average FHLB advances. AverageCorrespondingly, average non-interest bearing deposits increased by $90 million. We expect$1.6 billion to $9.0 billion for the three months ended March 31, 2022. These year-over-year trends in average balances were reflective of the operating environment as the U.S. economy began to emerge from the COVID-19 pandemic. Our ongoing strategy focused on improving the quality of our deposit base coupled with increased amounts of liquidity in the system led to growth in averagenon-interest bearing demand deposits to continue,and corresponding to anticipated growthdeclines in interest earning assets.bearing sources of funds. Headwinds to commercial loan growth including muted demand, our risk appetite given continued uncertainty about the ultimate impact of the pandemic, prepayments and supply chain constraints led to deployment of liquidity into the securities portfolio.

Average stockholders' equity increasedIn analyzing changes in the balance sheet for the quarter ended March 31, 2022, cash and investment securities grew by $255$891 million, due primarilywith securities growing by $508 million, at March 31, 2022 compared to December 31, 2021, while total loans declined by $395 million over the same period. Total deposits decreased by $897 million. This activity was offset by an increase of $1.5 billion in FHLB advances. Growth in the investment portfolio, which we did not initially anticipate would occur during the first quarter, reflected opportunistic purchases of securities at attractive spreads toward the end of the quarter. The most significant contributor to the retentiondecline in total loans was a decrease of earnings, but also reflecting proceeds from$391 million in mortgage warehouse loans as refinancing activity has slowed in response to rising interest rates. While total deposits declined during the exercisefirst quarter of stock options2022, non-interest bearing demand deposits grew by $688 million. The decrease in total deposits reflected declines in interest bearing demand, savings and an increasemoney market, and time deposits. The majority of deposit outflows were accounts that, based on prior experience, we would expect to be price sensitive in accumulated other comprehensive income.a rising rate environment and was consistent with our overall deposit strategy.

Our investment strategy has focused on insuring adequate liquidity, addingmaintaining a suitable balance of high credit quality, diversifyingdiverse assets, to the consolidated balance sheet, 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 securities, SBA securities and U.S. Government agency MBS.Agency and sponsored enterprise securities. Investment grade municipal securities provide liquidity along with higherand attractive tax-equivalent yields at longer durations than the portfolio in general.yields. We have also invested in highly rated structured products, including private-label commercial and residential MBS, collateralized loan obligations, single family real estate-backed securities and non-mortgage asset-backed securities that, while somewhat less liquid, provide us with attractive yields. Relatively short effective portfolio duration helps mitigate interest rate risk arising fromrisk. Based on the currently low level of market interest rates. TheCompany’s assumptions, the estimated weighted average expected life of the investment portfolio as of September 30, 2017March 31, 2022 was 4.94.4 years and the effective duration of the portfolio was 1.7 years.

Our evaluationRelevant market data;
Estimated prepayments, defaults, and the value and performance of non-agency impaired securities for OTTI as of September 30, 2017 included consideration of the potential impacts of Hurricanes Irma and Harvey. Our considerations included but were not necessarily limited to (i) observations of market pricing since the hurricanes, (ii) whether a significant portion of the underlying collateral was in an

impacted area, (iii) whether credit enhancement significantly exceededat the balance of collateral in impacted areas, (iv) for residential mortgage-backed securities, the evaluation of the extent and nature of damage to residential collateral for loans in the Bank’s residential loan portfolio located in the same areas, and (v) discussions with sponsors or managers of individual securities about specific collateral impact.
During the three and nine months ended September 30, 2016, OTTI was recognized on two positions in one private label commercial MBS. These positions were in unrealized loss positions at September 30, 2016 and the Company intended to sell the security before recovery of the amortized cost basis. No securities were determined to be other-than-temporarily impaired at September 30, 2017, or during the three and nine months then ended.level.
We do not intend to sell securities in significant unrealized loss positions at September 30, 2017.March 31, 2022. Based on an assessment of our liquidity position and internal and regulatory guidelines for permissible investments and concentrations, it is not more likely than not that we will be required to sell securities in significant unrealized loss positions prior to recovery of amortized cost basis.

Management's analysis of the credit characteristics of individual securities and the underlying collateral and levels of subordination for each of the single family rental real estate-backed securities in unrealized loss positions is not indicative of projected credit losses. Management's analysis of the state and municipal obligations in unrealized loss positions included reviewing the ratings of the securities and the results of credit surveillance performed by an independent third party.

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 an additional independent valuation specialist.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 have also established 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 or internal modeling, generally based on Intex. 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 specialist 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 certain preferred stocksmarketable equity securities are classified within level 1 of the hierarchy. At September 30, 2017 and December 31, 2016, 1.0% and 2.1%, respectively, of our investment securities were classified within level 3 of the fair value hierarchy. Securities classified within level 3 of the hierarchy at September 30, 2017 included certain private label residential MBS and trust preferred securities. These securities were classified within level 3 of the hierarchy because proprietary assumptions related to voluntary prepayment rates, default probabilities, loss severities and discount rates were considered significant to the valuation. There were no transfers of investment securities between levels of the fair value hierarchy during the nine months ended September 30, 2017 and 2016.

The non-covered1-4 single family residential loan portfolio, excluding government insured residential loans, is primarily comprised of loans purchased on a national basis through established correspondent channels. The portfolio also includes loans originated through retail channels in our Florida and New York geographic footprint prior to the termination of our retail residential mortgage origination business in early 2016. Non-covered1-4 single family residential mortgage loans are primarily closed-end, first lien jumbo mortgages for the purchase or re-finance of owner occupied property. The loans have terms ranging from 10 to 30 years, with either fixed or adjustable interest rates. At September 30, 2017, $113March 31, 2022, $927 million or 2.8%14% were secured by investor-owned properties.
The Company acquires non-performing FHA and VA insured mortgages from third party servicers who have exercised their right to purchase these loans out of non-covered residential mortgageGNMA securitizations (collectively, "government insured pool buyout loans" or "buyout loans"). Buyout loans were interest-onlythat re-perform, either through modification or self-cure, may be eligible for re-securitization.

The Company’s exposure to future losses on these mortgage loans is mitigated by the Single Family Shared-Loss Agreement.

Asset Quality
In discussing asset quality, we distinguish between covered loans and non-covered loans. Although the risk profile of covered loans is higher than that of non-covered loans, our exposure to loss related to covered loans is significantly mitigated by the fair value basis recorded in these loans resulting from the application of acquisition accounting and by the Single Family Shared-Loss Agreement. At September 30, 2017, residential loans covered under the Single Family Shared-Loss Agreement totaled $538 million.Commercial Loans
We have established a robust credit risk management framework, put in place an experienced team to lead the workout and recovery process for the commercial and commercial real estate portfolios and implemented a dedicated internal credit review function. We have an experienced resolution team in place for covered residential mortgage loans, and have implemented outsourcing arrangements with industry leading firms in certain areas such as OREO resolution. 
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. Additionally,Homogenous groups of smaller balance commercial loans may be monitored collectively. The credit quality and risk rating of commercial loans as well as our underwriting and portfolio management practices are regularly reviewed by our internal independent credit review department.
We believe internal risk rating is the best indicator of the credit quality of commercial loans. The Company utilizes a 13 grade16-grade internal asset risk classification system as part of its efforts to monitor and maintain commercial asset quality. LoansThe special mention rating is considered a transitional rating for loans exhibiting potential credit weaknesses that deserve management’s close attention and that if left uncorrected maycould result in deterioration of the repayment capacity of the borrower are categorized as special mention.prospects at some future date if not checked or corrected and that deserve management’s close attention. These borrowers may exhibit negative financial trendsdeclining cash flows or erratic financial performance, strained liquidity, marginal collateral coverage, declining industry trendsrevenues or weak management.increasing leverage. Loans with well-defined credit weaknesses that may result in a loss if the deficiencies are not corrected are assigned a risk rating of substandard. These borrowers may exhibit payment defaults, inadequate cash flows from current operations, operating losses, increasing balance sheet leverage, project cost overruns, unreasonable construction delays, exhausted interest reserves, declining collateral values, frequent overdrafts or past due real estate taxes. Loans with weaknesses so severe that collection in full is highly questionable

or improbable, but because of certain reasonably specific pending factors have not been charged off, are assigned an internal risk rating of doubtful.
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 FICO score to be significant indicators of credit quality for the non-covered 1-4 single family residential portfolio.
Although our assessment is ongoing and the results of that assessment are subject to change in the future, we do not currently believe the ability of the substantial majority of our borrowers to repay their loans or the value of the collateral securing those loans has been materially impacted by Hurricanes Irma and Harvey.
Non-covered Loans and Leases
Commercial Loans
The ongoing asset quality of significant commercial loans is monitored on an individual basis through our regular credit review and risk rating process. We believe internal risk rating is the best indicator of the credit quality of commercial loans. Homogenous groups of smaller balance commercial loans may be monitored collectively.

The balance of substandard loans at September 30, 2017 and December 31, 2016 included $121 million and $138 million, respectively, of taxi medallion finance loans. Criticized and classified loans represented 3.3%Our internal risk ratings at March 31, 2022 continued to be influenced by the impact of the COVID-19 pandemic and the measures and restrictions employed to contain the spread of the virus on the economy, our borrowers and the sectors in which they operate, although that impact continues to decline. Management took what it believed to be a proactive and objective approach to risk rating the commercial loan portfolio, of which 0.8% were taxi medallion loans, at September 30, 2017. See Note 4 to the consolidated financial statements for more detailed information about risk rating of commercial loans.

Taxi Medallion Finance
The commercial and industrial loan portfolio includes exposure to taxi medallion financeat the onset of $121 million at September 30, 2017. The estimated valuethe pandemic. Levels of underlying taxi medallion collateralcriticized and liquidityclassified loans, particularly in the market for salesspecial mention and substandard accruing categories, increased over the course of medallions,2020 as a potential secondary source of repayment, have declined significantly in recent years due to competitive developments in the transportation-for-hire industry. Due to the ongoing trend of declining estimated cash flows from the operation of taxi medallions leading to declines in medallion valuations, the entire taxi medallion portfolio was placed on non-accrual status and risk rated substandard as of September 30, 2017. In addition, partial charge-offs were recognized on all taxi medallion loans with carrying values in excess of collateral values, determined using the cash flow template discussed below, to reduce the carrying value of those loans to this estimated collateral value.
We update our analysis of the cash flow generating capacity of the operation of New York City medallions on a regular basis using current available taxi industry data from which taxi medallion values and prospective debt service capacity are estimated. This analysis is based on an extensive data set obtained from the NYTLC and assumptions that we believe are reasonable estimates of fleet utilization and borrower expenses. We update our analysis of estimated medallion valuations on a quarterly basis, based on these cash flow capacity estimates. At September 30, 2017, our estimate of the value of New York City taxi medallions based on our cash flow template and consideration of estimated selling costs and declining trends in medallion values was $351,000 for both corporate and individual medallions. We used this value for purposes of determining the partial charge-offs and the value of repossessed medallions. See Note 10 to the consolidated financial statements for additional information about the valuation of New York City taxi medallions.
The taxi medallion portfolio had the following characteristics at September 30, 2017:
Approximately 97% of the portfolio secured directly by taxi medallions was concentrated in New York City.
Loans delinquent by 30 days or more totaled $13.2 million or 11.0% of the portfolio, compared to $40.8 million or 22.8% of the portfolio at December 31, 2016. Loans delinquent by 90 days or more totaled $10.4 million or 8.7% of the portfolio, compared to $29.2 million or 16.4% of the portfolio at December 31, 2016. The most significant factor contributing to the decrease in delinquencies was one large relationship that was brought current and restructured in the first quarter.
The portfolio included 173 loans modified in TDRs with a recorded investment of $92.4 million.
In the aggregate, the ALLL related to taxi medallion loans was 10.9% of the outstanding balance at September 30, 2017, compared to 6.0% at December 31, 2016. Charge-offs of $35.3 million and $47.1 million were recognized in the three and nine months ended September 30, 2017 related to taxi medallion loans.
We are no longer originating new taxi medallion loans. Our portfolio management strategies include, but are not limited to, working with borrowers experiencing cash flow challenges to provide short term relief and/or extended amortization periods, pro-actively attempting to refinance loans prior to maturity, continuing to monitor industry data and obtaining updated borrower and guarantor financial information. As taxi medallion loans approach maturity or are refinanced, we expect the number and amount of TDRs in this portfolio segment to continue to increase.
Hurricane Impact - Commercial Loans
Commercial loans totaling $1.9 million and $19.4 million had been modified or granted temporary payment deferrals as of September 30, 2017 and October 31, 2017, respectively, related to the recent hurricanes. Of these modifications and deferrals, none were determined to be TDRs due to the generally insignificant nature of the payment delays.
As of September 30 and October 31, 2017, respectively, commercial loans to borrowers that have significant business operations in or are secured by collateral in areas impacted by Hurricanes Irma and Harvey totaling approximately $4.7 million and $21.3 million were more than 30 days past due; $3.7 million of these loans were more than 30 days past due prior to the storms. Approximately $22.2 million of commercial loans have been downgraded to criticized or classified status through October 31, 2017 as adirect result of the impact of the storms.COVID-19 pandemic. Throughout 2021 and the three months ended March 31, 2022, levels of criticized and classified loans declined in response to the trajectory of the economic recovery. If the economic recovery and its impact on individual borrowers evolve in line with our current expectations and economic forecast, we would expect to see the level of criticized and classified loans continue to decline over the course of 2022. However, uncertainty remains around the future trajectory of the economy due to a number of factors. In light of that uncertainty, it is possible that criticized and classified loan levels may not decline or that they may increase.

Payment Deferrals and Modifications
At March 31, 2022, commercial loans under CARES Act modification totaled $117 million. All of the commercial loans that have rolled off of modification have paid off or resumed regular payments. CARES Act modifications most commonly have taken the form of 9 to 12 month interest only periods. The majority of loan modifications that took place after the onset of the COVID-19 pandemic and through December 31, 2021 were not categorized as TDRs, in accordance with interagency and authoritative guidance and the provisions of the CARES Act, which expired effective January 1, 2022.
Operating Lease Equipment, net
FourThree operating lease relationships with assets under leaseleases with a carrying value of assets under lease totaling $81$18 million, all of which $75 million were exposures to the energy industry, were internally risk rated special mention or substandard at September 30, 2017. The presentMarch 31, 2022. On a quarterly basis, management performs an impairment analysis on assets with indicators of potential impairment. Potential impairment indicators include evidence of changes in residual value, macro-economic conditions, an extended period of remaining lease payments on these leases totaled approximately $22 milliontime off-lease, criticized or classified status, or management's intention to sell the asset at September 30, 2017, of which $17 millionan amount potentially below its carrying value.

The primary risks inherent in the equipment leasing business are asset risk resulting from ownership of the equipment on operating lease and credit risk. Asset risk arises from fluctuations in supply and demand for the underlying leased equipment. Railcars are long-lived equipment with useful lives of approximately 35-50 years. The equipment is leased to commercial end-usersend users with original lease terms generally ranging from 3-9 years at September 30, 2017.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 operating leaseleased assets or through impairment of asset carrying values.
47





Asset risk is evaluated and managed by a dedicated internal staff of asset managers, managed by seasoned equipment finance professionals with a broad depth and breadth of experience in the leasing business. Additionally, we have partnered with an industry leading, experienced service provider who provides fleet management and servicing relating to the railcar fleet, including lease administration and reporting, a Regulation Y compliant full service maintenance program and railcar re-marketing. Risk is managed by setting appropriate residual values at inception and systematic reviews of residual values based on independent appraisals, performed at least annually. Additionally, our internal management team and our external service provider closely follow the rail markets, monitoring traffic flows, supply and demand trends and the impact of new technologies and regulatory requirements. Demand for railcars is sensitive to shifts in general and industry specific economic and market trends and shifts in trade flows from specific events such as natural or man-made disasters. We seek to mitigate these risks by leasing to a stable end-userend 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 lower 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 utilizingusing 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 only to high credit quality obligors.
We expect ourBridge had exposure to the energy industry of $272 million at March 31, 2022. The majority of the energy exposure was in the operating lease equipment portfolio to continue to grow,where energy exposure totaled $235 million. The remaining energy exposure, totaling approximately $37 million was comprised of loans and we may expand into other asset classes.
Based on our initial analysis of the location and condition of equipment under operating lease, we do not currently believe there has been any significant damage to such equipmentdirect or to the ongoing operations of lessees from Hurricanes Irma and Harvey.sales type finance leases.
Residential and Other Consumer Loans
The majority of our non-coveredOur residential mortgage portfolio, excluding GNMA buyout loans, consists primarily of loans purchased through established correspondent channels. In general, we purchaseMost 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.

Covered Loans
At September 30, 2017, residential ACI loans totaled $476 million and residential non-ACI loans totaled $62 million, including premiums, discounts and deferred fees and costs. Allless than 1% of these loans are covered under the Single Family Shared-Loss Agreement.
Covered residential loans were placed into homogenous pools at the time of the FSB Acquisition and the ongoing credit quality and performance of these loans is monitored on a pool basis. We monitor the pools quarterly to determine whether any changes have occurred in expected cash flows that would be indicative of impairment or necessitate reclassification between non-accretable difference and accretable yield. At September 30, 2017, accretable yield on residential ACI loans totaled $511 million and non-accretable difference related to those loans totaled $227 million.
At September 30, 2017, the recorded investment in non-ACI 1-4 single family residential loans, was $24.6 million; $1.6 million or 6.6% of these loans were 30 days or more past due and $0.9 million or 3.8% of these loans were 90 days or more past due.

At September 30, 2017, non-ACI home equity loans and lines of credit had an aggregate recorded investment of $37.4 million; $4.1 million or 11.1% of these loans were 30 days or more past due and $2.4 million or 6.3% were 90 days or more past due. ACI home equity loans and lines of credit had a carrying amount of $5.6 million at September 30, 2017; 13.5% of these loans were delinquent by 30 days or more.
Home equity lines of credit generally provide that payment terms be reset after an initial contractual period of interest only payments, requiring the pay down of principal through balloon payments or amortization.

The Company's exposure to loss related to covered loans is significantly mitigated by the Single Family Shared-Loss Agreement and by the fair value basis recorded in these assets resulting from the application of acquisition accounting. Management regularly evaluates the impact of resets of interest only loans on default rates for the covered home equityloan portfolio.
Impaired Loans and 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 ACIPCD 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. Impaired loans also typically include loans modified in TDRs that are accruing and ACI loans or pools for which expected cash flows at acquisition (as adjusted for any additional cash flows expected to be collected arising from changes in estimates after acquisition) have been revised downward since acquisition, other than due to changes in interest rate indices and prepayment assumptions.OREO.

The following chart presents trends in non-accrual taxi medallion loans.

Contractually delinquent ACI loans with remaining accretable yield are not reflected as non-accrual loans and are not considered to be non-performing assets because accretion continues to be recorded in income. Accretion continues to be recorded as long as there is an expectation of future cash flows in excess of carrying amount from these loans. The carrying value of ACI loans contractually delinquent by more than 90 days but on which income was still being recognized was $18 million and $16 million at September 30, 2017 and December 31, 2016, respectively.bku-20220331_g7.jpg
New commercialCommercial 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. NewResidential and non-ACI residential and consumer loans, other than government insured pool buyout loans, are generally placed on non-accrual status when they are 90 days past due. Residential loans that have rolled off of interest is dueshort-term deferral and unpaid.have not caught up on their deferred payments may also be placed on non-accrual; these loans are typically pending modification. When a loan is placed on non-accrual status, uncollected interest accrued is reversed and
charged to interest income. Commercial loans are returned to accrual status only after all past due principal and interest has been collected and full repayment of remaining contractual principal and interest is reasonably assured. Residential loans are generally returned to accrual status when less than 90 days of interest is due and unpaid.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, or in some cases, partial forgiveness of principal. Under GAAP, modified ACI loans accounted for in pools are not accounted for as TDRs and are not separated from their respective pools when modified.terms. Included in TDRs are residential loans to borrowers who have not reaffirmed their debt discharged in Chapter 7 bankruptcy.
Under inter-agency and authoritative guidance and consistent with the CARES Act, short-term deferrals or modifications related to COVID-19 were typically not categorized as TDRs. Additionally, section 4013 of the CARES Act, as amended by the Consolidated Appropriations Act, effectively suspended the guidance related to TDRs codified in ASC 310-40 until January 1, 2022, the date the CARES Act expired.

These loans are typically performing, but possess specifically identified credit weaknesses that, if not remedied, may lead to a downgrade to non-accrual status and identification as impaired in the near-term. Substandard accruing commercial loans totaled $185TDRs totaling $123.9 million at September 30, 2017, substantially all of which were current asMarch 31, 2022, and 435 government insured residential loans modified in TDRs totaling $76.4 million at December 31, 2021.

Loss Mitigation Strategies
Criticized or classified commercial loans in excess of certain thresholds are reviewed quarterly by the Criticized Asset Committee, which determinesevaluates the appropriate strategy for collection to mitigate the amount of credit losses.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; impairedsubstandard, loans on non-accrual status;status, loans modified as TDRs; taxi medallion loans;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 Recovery Committee.
WeOur servicers evaluate each residential loan in default to determine the most effective loss mitigation strategy, which may be modification, short sale, or foreclosure. Throughforeclosure, and pursue the program's expirationalternative most suitable to the consumer and to mitigate losses to the bank.
In response to the COVID-19 pandemic and its potential economic impact to our customers, we implemented a short-term program that complies with interagency guidance and the CARES Act under which we have provided temporary relief, and in some cases longer term modifications, on a case by case basis to borrowers directly impacted by COVID-19 who were not more than 30 days past due as of December 31, 2016, we offered loan modifications under2019. See the HAMP program to eligible borrowers in the residential portfolio. HAMP is a uniform loan modification process that provides eligible borrowers with sustainable monthly mortgage payments equal to a target 31% of their gross monthly income. We began offering a new modification program in late 2016 modeled after the FNMA standard modification program.sections entitled "Asset Quality - Commercial Loans - Payment Deferrals" and "Asset Quality - Residential and Other Consumer Loans" for further details about COVID-19 related payment deferrals and modifications.
In addition to the modification programs discussed above, we offer a proprietary Subordinate Lien Modification Program for home equity loans and lines of credit. This provides BankUnited the ability to offer a modification on loans covered under the Single Family Shared-Loss Agreement that are subordinate to either a BankUnited first lien or a first lien from another lender.
Analysis of the Allowance for Loan and LeaseCredit Losses
The ALLL relates to (i) new loans, (ii) estimated additional losses arising on non-ACI loans subsequent to the FSB Acquisition, and (iii) impairment recognized as a result of decreases in expected cash flows on ACI loans due to further credit deterioration. The impact of any additional provision for losses on covered loansACL is significantly mitigated by an increase in the FDIC indemnification asset. The determinationmanagement's estimate of the amount of expected credit losses over the ALLLlife 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 by nature, highly

complex and subjective. Future eventsrequires extensive judgment by management about matters that are inherently uncertainuncertain. Economic uncertainty remains around the impact the continually evolving COVID-19 situation, emerging inflationary concerns and current geopolitical events will have on the economy broadly, and on our borrowers specifically. Given this uncertainty, the complexity of the ACL estimate and level of management judgment required, we believe it is possible that the ACL estimate could change, potentially materially, in future periods, in either direction. Changes in the ACL may result from changes in current economic conditions, our economic forecast, loan portfolio composition and circumstances not currently known to us that may impact the financial condition and operations of our borrowers, among other factors.
Expected credit losses are estimated on a collective basis for groups of loans that share similar risk characteristics. For loans that do not share similar risk characteristics with other loans such as collateral dependent loans and TDRs, expected credit losses are estimated on an individual basis. Expected credit losses are estimated over the contractual terms of the loans, adjusted for expected prepayments, generally excluding expected extensions, renewals, and modifications.
For the substantial majority of portfolio segments and subsegments, including residential loans other than government insured loans, and most commercial and commercial real estate loans, expected losses are estimated using econometric models. The models employ a factor based methodology, leveraging data sets containing extensive historical loss and recovery information by industry, geography, product type, collateral type and obligor characteristics, to estimate PD and LGD. Measures of PD for commercial loans incorporate current conditions through market cycle or credit cycle adjustments. For residential loans, the models consider FICO and adjusted LTVs. PDs and LGDs are then conditioned on the reasonable and supportable economic forecast. Projected PDs and LGDs, determined based on pool level characteristics, are applied to estimated exposure at default, considering the contractual term and payment structure of loans, adjusted for prepayments, to generate estimates of expected loss. For criticized or classified loans, PDs are adjusted to benchmark PDs established for each risk rating. The ACL estimate incorporates a reasonable and supportable economic forecast through the use of externally developed macroeconomic scenarios applied in the models.
A single economic scenario or a probability weighted blend of economic scenarios may be used. The models ingest numerous national, regional and MSA level variables and data points. At both March 31, 2022 and December 31, 2021, a baseline scenario provided by an external party was used in estimating the ACL.
Commercial Real Estate Model
Variables with the most significant impact on the commercial real estate model include unemployment at both national and regional levels, the CRE property forecast by property type and sub-market, 10 year treasury yield, Baa corporate yield and real GDP growth, at the national level. Increases in unemployment and yields within the commercial real estate model result in material changes toincreases in the level ofACL. Increases in real GDP growth and improvements in the ALLL. General economic conditions including but not limited toCRE property forecasts reduce the reserve.
Commercial Model
Variables with the most significant impact on the commercial model include a stock market volatility index, the S&P 500 index, unemployment rates, the level of business investmentat both national and growth, real estate values, vacancy ratesregional levels, and rental rates in our primary market areas, the levela variety of interest rates and a variety of other factors that affectspreads. Increases in the ability of borrowers’ businesses to generate cash flows sufficient to service their debts will impactunemployment rate, the future performancestock market volatility index, and the Baa corporate yield increase the reserve, while increases in real GDP growth and the steepening of the portfolio. 
New and non-ACILoansyield curve reduce the reserve.
Residential Model
Variables with the most significant impact on the residential model include HPI and other consumerunemployment at regional levels, real GDP growth, and a 30 year mortgage rate. Increases in the unemployment rate and the 30-year mortgage rate increase the reserve, while increases in real GDP growth and HPI reduce the reserve.
DueThe 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 the lack of similarity between the risk characteristics of newlong-term mean losses on a straight-line basis over 12 months.
For certain less material portfolios including loans and coveredleases to state and local government entities originated by Pinnacle, small balance commercial loans inand consumer loans, the residential and home equity portfolios, management does not believe it is appropriate to use the historical performance of the covered residential mortgage portfolio as a basis for calculating the ALLL applicable to new loans. The new loan portfolio has not yet developed an observable loss trend. Therefore, the ALLL for new residential loans is based primarily on relevant proxy historical loss rates. The ALLL for new 1-4 single family residential loans is estimated using average annual loss rates on prime residential mortgage securitizations issued between 2003 and 2008 as a proxy. Based on the comparability of FICO scores and LTV ratios between loans included in those securitizations and loans in the Bank’s portfolio and the geographic diversity in the new purchased residential portfolio, we determined that prime residential mortgage securitizations provide an appropriate proxy for incurred losses in this portfolio class. A peer group 16-quarter average net charge-off rateWARM method is used to estimate the ALLL for the new home equity and other consumer loan classes. See further discussion of the use of peer group loss factors below. The new home equity and other consumer loan portfoliosexpected credit losses. Loss rates are not significant components of the overall loan portfolio.
Based on an analysis of historical performance, OREO and short sale losses, recent trending data and other internal and external factors, we have concluded that historical performance by portfolio class is the best indicator of incurred loss for the non-ACI 1-4 single family residential and home equity portfolio classes. For each of these portfolio classes, a quarterly roll rate matrix is calculated by delinquency bucket to measure the rate at which loans move from one delinquency bucket to the next during a given quarter. An average 16-quarter roll rate matrix is used to estimate the amount within each delinquency bucket expected to roll to 120+ days delinquent. We assume no cure for those loans that are currently 120+ days delinquent. Loss severity given default is estimated based on internal data about OREO sales and short sales from the portfolio. The ALLL calculation incorporates a 100% loss severity assumption for home equity loans that are projected to roll to default. For non-ACI residential loans, the allowance is initially calculated based on UPB. The total of UPB less the calculated allowance is then compared to the carrying amount of the loans, net of unamortized credit related fair value adjustments established at acquisition. If the calculated balance net of the allowance is less than the carrying amount, an additional allowance is established. Any increase or decrease in the allowance for non-ACI residential loans will result in a corresponding increase or decrease in the FDIC indemnification asset. 
Commercial
The allowance is comprised of specific reserves for loans that are individually evaluated and determined to be impaired as well as general reserves for loans that have not been identified as impaired.
Commercial relationships graded substandard or doubtful and on non-accrual status with committed credit facilities greater than or equal to $1.0 million as well as loans modified in TDRs are individually evaluated for impairment. Other commercial

relationships on non-accrual status with committed balances under $1.0 million may also be evaluated for impairment, at management's discretion. For loans evaluated individually for impairment and determined to be impaired, a specific allowance is established based on the present value of expected cash flows discounted at the loan’s effective interest rate, the estimated fair value of the loan, or the estimated fair value of collateral less costs to sell. We recognized partial charge-offs at September 30, 2017 on taxi medallion loans all of which are risk-rated substandard and on non-accrual status, as necessary to reduce the carrying value of the loans to our estimate of the value of New York City taxi medallions based on our cash flow template. Additionally, a specific allowance was recognized equal to the amount by which each loan exceeded 85% of the estimated value, in recognition of the continued declining trend in cash flows and lower prices observed on certain recent taxi medallion transfers. The amount of this specific allowance was determined based on management's judgment.
We believe that loans rated special mention, substandard or doubtful that are not individually evaluated for impairment exhibit characteristics indicative of a heightened level of credit risk. We apply a quantitative loss factor for loans rated special mention based on average annual probability of default and implied severity, derived from internal and external data. Loss factors for substandard and doubtful loans that are not individually evaluated are determined by using default frequency and severity information applied at the loan level. Estimated default frequencies and severities are based on available industry data. In addition, we apply a floor to these calculated loss factors, based on the loss factor applied to the special mention portfolio.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.
Since

The Company expects to collect the majorityamortized cost basis of government insured residential loans and PPP loans due to the nature of the new commercial loan portfoliogovernment guarantee, so the ACL is not yet seasoned enough to exhibit a loss trend, the quantitative loss factorszero for a majority of pass rated new commercial loans is based on peer group average annual historical net charge-off rates by loan class and the Company’s internal credit risk rating system. Beginning in the first quarter of 2017, we revised the source of quantitative loss factors for certain loans, as follows:
Given the emergence of observable loss trends, the quantitative loss factors for the taxi medallion and Bridge portfolios are based on the Company’s average historical net charge-off rates. Beginning in the third quarter of 2017, all taxi medallion loans are individually evaluated for impairment as described above.
The general quantitative loss factor for municipal finance receivables is based on the portfolio's external ratings and Moody's historical transition matrix, as opposed to the historical cumulative default curve for municipal obligations that was used previously.
For loans that are partially guaranteed by the SBA, the loss factor applied to the non-guaranteed portion of these loans is based on the 16-quarter average charge-off rate published by the SBA for each program
Mortgage warehouse loans have been segregated for the purpose of determining a quantitative loss factor, to better recognize the risk profile of this portfolio segment.
The net impact of these changes on the ALLL was not material.
The peer group used to calculate the average annual historical net charge-off rates that form the basis for our general reserve calculations for the majority of new commercial, home equity and consumer loans is made up of the banks included in the OCC Midsize Bank Group plus two additional banks in the New York region that management believes to be comparable based on size and nature of lending operations. The OCC Midsize Bank Group primarily includes commercial banks with total assets ranging from $10 - $50 billion and included 28 banks at September 30, 2017. Peer bank data is obtained from the Statistics on Depository Institutions Report published by the FDIC for the most recent quarter available. These banks, as a group, are considered by management to be comparable to BankUnited in size, nature of lending operations and loan portfolio composition. We evaluate the composition of the peer group annually, or more frequently if, in our judgment, a more frequent evaluation is necessary. Our internal risk rating system comprises 13 credit grades; grades 1 through 8 are “pass” grades. The risk ratings are driven largely by debt service coverage. Peer group historical loss rates are adjusted upward for loans assigned a lower “pass” rating.
We use a 16-quarter loss experience period to calculate peer group average annual net charge-off rates for commercial loans. We believe this look-back period to be consistent with the range of industry practice and appropriate to capture a sufficient range of observations reflecting the performance of our loans, most of which were originated in the current economic cycle. Prior to the third quarter of 2017, we used a four-quarter loss experience period for the taxi medallion portfolio to recognize the recent deterioration in that portfolio. We use a 14-quarter loss experience period for the Bridge portfolios, reflective of the period over which an observable loss trend began to emerge.
With the exception of the Pinnacle municipal finance portfolio, a four quarter loss emergence period is used in the calculation of general reserves. A twelve quarter loss emergence period is used in the calculation of general reserves for the Pinnacle portfolio.

Qualitative Factorsfactors
Qualitative adjustments are made to the ALLLACL when, based on management’s judgment, there are internal or external factors impacting probable incurredexpected credit losses not taken into account by the quantitative calculations. Potential qualitative adjustments are categorized as follows:
Portfolio performance trends, including trends in and the levels of delinquencies, non-performing loans and classified loans;  Economic factors;
Changes in the nature of the portfolio and terms of the loans, specifically including the volume and nature ofCredit policy and procedural exceptions;staffing;
Portfolio growth trends;  Concentrations;
Changes in lending policiesModel imprecision; and procedures, including credit and underwriting guidelines;  
Economic factors, including unemployment rates and GDP growth rates;
Changes in the value of underlying collateral;
Quality of risk ratings, as evaluated by our independent credit review function;  
Credit concentrations;  
Changes in and experience levels of credit administration management and staff; and
Other factors identifieddeemed appropriate by management that may materially impact the level of losses inherent in the portfolio, including but not limited to competition and legal and regulatory considerations.
ACILoans
For ACI loans, a valuation allowance is established when periodic evaluationsamount of expected cash flows reflect a deterioration resulting from credit related factors fromlosses.
See Note 1 to the level of cash flows that were estimated to be collected at acquisition plus any additional expected cash flows arising from revisions in those estimates. We perform a quarterly analysis of expected cash flows for ACI loans.
Expected cash flows are estimated on a pool basis for ACI 1-4 single family residential and home equity loans. The analysis of expected pool cash flows incorporates updated pool level expected prepayment rate, default rate, delinquency level and loss severity given default assumptions. Prepayment, delinquency and default curves are derived primarily from roll rates generated from the historical performanceconsolidated financial statements of the portfolio over the immediately preceding four quarters. Loss severity given default assumptions are generated from the historical performance of the portfolio over the immediately preceding four quarters, while loss severity from loan sales is generated from historical performance over the immediately preceding twelve quarters. Estimates of default probability and loss severity given default also incorporate updated LTV ratios, at the loan level, basedCompany's 2021 Annual report on Case-Shiller Home Price IndicesForm 10-K for the relevant MSA. Costs and fees represent an additional component of loss on default and are projected based on historical experience over the last three years. The ACI home equity roll rates include the impact of delinquent, related senior liens and loans to borrowers who have not reaffirmed their debt discharged in Chapter 7 bankruptcy. 
Our projected cash flow analysis reflected a decrease in expected cash flows due to credit related factors for the home equity ACI pool; therefore, a provision for loan losses of $1.8 million was recorded for the nine months ended September 30, 2017, along with a corresponding increase in the FDIC indemnification asset of $1.4 million. No ALLL related to 1-4 single family residential ACI pools was recorded at September 30, 2017. No ALLL related to 1-4 single family residential and home equity ACI pools was recorded at December 31, 2016.
The primary assumptions underlying estimates of expected cash flows for ACI commercial loans are default probability and severity of loss given default. Assessments of default probability and severity are based on net realizable value analyses prepared at the individual loan level. Based onmore detailed information about our analysis, no ALLL related to ACI commercial loans was recorded at September 30, 2017 or December 31, 2016.

Significant offsetting factors contributing to the impact of Hurricanes Irma and Harvey. The ALLL includes $0.4 million related to loans that were downgradedchange in the ACL during the three months ended September 30, 2017 as a resultMarch 31, 2022 are depicted in the chart below (in millions):
bku-20220331_g8.jpg
Changes in the ACL during the three months ended March 31, 2022
The ACL for the CRE portfolio sub-segment, including multi-family, non-owner occupied CRE and construction and land, increased by $4.7 million during the three months ended March 31, 2022, from 0.51% to 0.61% of loans. The increase in the hurricanes and a $5.0 million unallocated qualitative allowance.
Excluding the $5.0 million unallocated qualitative allowance relative to the impact of the hurricanes, the balance of the ALLLACL for non-covered loans at September 30, 2017 decreased slightly as compared to December 31, 2016. Decreases in quantitative loss factors applied to the majority of the commercial loan portfolio and net decreases in qualitative factors were substantially offsetCRE was driven mainly by the impact of the growth of the loan portfolio and an increase in reserves for criticized and classified loans, including taxi medallion loans. Factors influencing the change in the ALLL related to specific loan types at September 30, 2017 as compared to December 31, 2016, include:
The ALLL related to non-covered 1-4 single family residential loans did not change significantly. Increases related to growth in the corresponding portfolio were substantially offset by declines in both the applicable quantitative historical loss rate and qualitative reserves.
A decrease of $3.3 million for multi-family loans primarily reflects decreases in quantitative loss factors, the decline in the corresponding portfolio and a net decrease in qualitative loss factors, offset in part by an increase in criticized and classified loans.
An increase of $3.9 million for non-owner occupied commercial real estate loans was primarily driven by the growth of the corresponding portfolio and an increase in criticized and classified loans, partially offset by a decrease in quantitative loss factors.
An increase of $3.7 million for owner occupied commercial real estate loans was primarily attributable to increases in specific reserves for impaired loans and to a lesser extent, the growth of the corresponding portfolio.
An increase of $2.5 million for taxi medallion loans reflects the specific reserves recognized at September 30, 2017, as discussed previously. Increases in reserves were limited due to the level of charge-offs recognized during the nine months ended September 30, 2017.
A decrease of $0.8 million for other commercial and industrial loans was primarily driven by a decrease in reserves for impaired and other classified loans, primarily due to net charge-offs, offset by growth in the corresponding portfolio.
A $8.0 million decrease for commercial lending subsidiaries primarily reflects decreases in quantitative loss factors for the municipal finance receivables and decreases in qualitative loss factors related to economic uncertainty, partially offset by net charge-offs.
The ACL for the commercial and industrial sub-segment, including owner-occupied commercial real estate, decreased by $2.2 million during the three months ended March 31, 2022. Significant factors contributing to the decrease included (i) the decline in criticized and classified loans; (ii) a decrease related to the impact of the economic forecast; and (iii) a decrease in specific reserves; partially offset by (iv) a decrease in estimated prepayment speeds; and (v) the increase in qualitative loss factors related to economic uncertainty. The ACL coverage ratio for these loans increased from 0.84% to 0.86% during the three months ended March 31, 2021 despite the decline in the ACL. This was driven by the decline in the amortized cost basis of MWL and PPP loans, which carry nominal or no reserves, during the quarter.
The ACL for the BFG franchise finance portfolio segment decreased by $2.3 million during the three months ended March 31, 2022, from 4.90% to 4.71% of loans. This decrease is primarily attributed to reduced levels of criticized and classified loans and improvements in the economic forecast.
The ACL for the BFG equipment finance portfolio segment decreased by $0.9 million during the three months ended March 31, 2022, from 1.00% to 0.78% of loans, resulting primarily from risk rating upgrades, and to a lesser extent, faster prepayment speed assumptions partially offset by an increase in qualitative factors related to economic uncertainty.
The estimate of the ACL at March 31, 2022 was informed by economic scenarios published in March 2022, developments emerging after the scenarios were published, economic information provided by additional sources, information about borrower financial condition and collateral values and other relevant information. The economic forecast used in modeling the ACL as of March 31, 2022 was a third-party provided baseline forecast. Some of the assumptions and data points informing the reasonable and supportable economic forecast used in estimating the ACL at March 31, 2022 included:
53





Labor market assumptions, which reflected national unemployment at 3.7% for the second quarter of 2022, steadily declining to normalized levels of full employment of 3.5% through the end of 2022 and 3.4% throughout 2023;
Annualized growth trendsin GDP at 4.8% for the second quarter of 2022, normalizing to an average of 3.4% and credit concentrations.3.2% for 2022 and 2023;
VIX trending at stabilized levels through the forecast horizon; and
S&P 500 averaging near 4,200 through the reasonable and supportable forecast period.
Additional variables and assumptions not explicitly stated, including but not limited to residential and commercial property forecasts, also contributed to the overall impact economic conditions and the economic forecast had on the ACL estimate. Furthermore, while the variables presented above are at the national level; many of the variables are regionalized at the market and submarket level in the models.

FHLB Advances, Notes and Other Borrowings
In addition to deposits, we utilize FHLB advances to fund growth in interest earning assets;as a funding source; the advances provide us with additional flexibility in managing both term and cost of funding.funding and in managing interest rate risk. FHLB advances are secured by FHLB stock, qualifying residential first mortgage and commercial real estate and home equity loans, and MBS.

Liquidity and Capital Resources
Liquidity involves our ability to generate adequate funds to support planned interest earning asset growth, meet deposit withdrawal and credit line usage requests, maintain reserve requirements, conduct routine operations, pay dividends, service outstanding debt and meet other contractual obligations.
BankUnited's ongoing liquidity needs have been and continue to be met primarily by cash flows from operations, deposit growth, the investment portfolio and FHLB advances. FRB discount window borrowings provide an additional source of contingent liquidity. For the three months ended March 31, 2022 and 2021 net cash provided by operating activities was $457 million and $386 million, respectively.
Available liquidity includes cash, borrowing capacity at the Federal Home Loan Bank of Atlanta and the Federal Reserve Discount Window, Federal Funds lines of credit and unpledged agency securities. Additional sources of liquidity include cash flows from operations, wholesale deposits, cash flow from the Bank's amortizing securities and loan portfolios, and the sale of investment securities. Management also has the ability to exert substantial control over the rate and timing of loan production, and resultant requirements for liquidity to fund new loans.
The ALM policy establishes limits or operating thresholds and guidelines for a number of measures of liquidity which are typically monitored monthly by the ALCO and quarterly by the Board of Directors. The primary measures used to dimension liquidity risk are the ratio of available liquidity to volatile liabilities and a liquidity stress test coverage ratio. Other measures employed to monitor and manage liquidity include but are not limited to a 30-day total liquidity ratio, a one-year liquidity ratio, a wholesale funding ratio, concentrations of large deposits, a measure of on-balance sheet available liquidity, the ratio of FHLB advances to total assets and the ratio of non-interest bearing deposits to total deposits, which is reflective of the quality and cost, rather than the quantity, of available liquidity. At March 31, 2022, BankUnited was in compliance with the limits prescribed by the ALM policy.

The ALM policy stipulates that BankUnited’s liquidity is within policy limits if the available liquidity/volatile liabilities ratio and liquidity stress test ratios exceed 100%. At March 31, 2022, BankUnited’s available liquidity/volatile liabilities ratio was 309% and the liquidity stress test ratio was 188%. The Company has a comprehensive contingency liquidity funding plan and conducts a quarterly liquidity stress test, the results of which are reported to the risk committee of the Board of Directors.
Senior notes haveAs a face amountholding 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 $400 million, a fixed coupon ratefunds 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 4.875%the Bank to pay dividends to BankUnited, Inc. Management believes that such limitations will not impact our ability to meet our ongoing near-term cash obligations.
We expect that our liquidity needs and mature on November 17, 2025.
Capital Resourcescash requirements will continue to be satisfied over the next twelve months through the sources of funds described above.

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.
SinceWe believe we are well positioned, from a capital perspective, to withstand a severe downturn in the economy. We continue to evolve our formation, stockholders' equity has been impacted primarily by the retention of earnings,stress testing framework and adapt it to a lesser extent, proceeds from the issuance of common shares and changes in unrealized gains and losses, net of taxes, on investment securities

available for sale and cash flow hedges. Our rate of earnings retention is derived by dividing undistributed earnings per common share by earnings per common share. Our retention ratio was 66.0% and 64.9% for the three and nine months ended September 30, 2017, respectively, compared to 55.7% and 58.4% for the three and nine months ended September 30, 2016, respectively. We retain a high percentageevolving macro-economic conditions as necessary. The majority of our earningscommercial portfolio is subject to supportquarterly stress test analysis. On an annual basis, we also run a rigorous stress test of our planned growth.entire balance sheet and, where applicable, we incorporate considerations for evolving macro-economic themes.
We filed ahave an active shelf registration statement on file with the SEC in October 2015 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.

Levels of capital required to be well capitalized or adequately capitalized as reflected above do not include a capital conservation buffer that is being phased in beginning in 2016. When fully phased in on January 1, 2019, the Bank and the Company will have to maintain this capital conservation buffer composed of CET1 capital equal to 2.50% of risk-weighted assets above the amounts required to be adequately capitalized, as reflected above, in order to avoid limitations on capital distributions, including dividend payments and certain discretionary bonus payments to executive officers. Capital ratios required to be considered well-capitalized exceed the ratios required under the capital conservation buffer requirement at September 30, 2017.
Liquidity
Liquidity involves our ability to generate adequate funds to support planned interest earning asset growth, meet deposit withdrawal requests, maintain reserve requirements, conduct routine operations, pay dividends, service outstanding debt and meet other contractual obligations.
Primary sources of liquidity include cash flows from operations, cash generated by the repayment and resolution of covered loans, cash payments received from the FDIC pursuant to the Single Family Shared-Loss Agreement, deposit growth, the available for sale securities portfolio and FHLB advances.
For the nine months ended September 30, 2017 and 2016, net cash provided by operating activities was $231.2 million and $227.3 million, respectively. Accretion on ACI loans, which is reflected as a non-cash reduction in net income to arrive at operating cash flows, totaled $226.3 million, and $228.5 million for the nine months ended September 30, 2017 and 2016, respectively. Accretable yield on ACI loans represents the excess of expected future cash flows over the carrying amount of the loans, and is recognized as interest income over the expected lives of the loans. Amounts recorded as accretion are realized in cash as individual loans are paid down or otherwise resolved; however, the timing of cash realization may differ from the timing of income recognition. These cash flows from the repayment or resolution of covered loans, inclusive of amounts that have been accreted through earnings over time, are recognized as cash flows from investing activities in the consolidated statements of cash flows upon receipt. Cash payments from the FDIC in the form of reimbursements of losses related to the

covered loans under the Single Family Shared-Loss Agreement are also characterized as investing cash flows. Cash generated by the repayment and resolution of covered loans and reimbursements from the FDIC totaled $348.5 million and $430.3 million for the nine months ended September 30, 2017 and 2016, respectively. Both cash generated by the repayment and resolution of covered loans and cash payments received from the FDIC have been and are expected to continue to be, although to a lesser extent in the future, consistent and relatively predictable sources of liquidity.
In addition to cash provided by operating activities, the repayment and resolution of covered loans and payments under the Single Family Shared-Loss Agreement from the FDIC, BankUnited’s liquidity needs, particularly liquidity to fund growth of interest earning assets, have been and continue to be met by deposit growth and FHLB advances. The investment portfolio also provides a source of liquidity.
BankUnited has access to additional liquidity through FHLB advances, other collateralized borrowings, wholesale deposits or the sale of available for sale securities. At September 30, 2017, unencumbered investment securities available for sale totaled $4.3 billion. At September 30, 2017, BankUnited had available borrowing capacity at the FHLB of $3.8 billion, unused borrowing capacity at the FRB of $544 million and unused Federal funds lines of credit totaling $70 million. Management also has the ability to exert substantial control over the rate and timing of growth of the non-covered loan portfolio, and resultant requirements for liquidity to fund loans.
Continued runoff of the covered loan portfolio and FDIC indemnification asset and growth of deposits and the non-covered loan portfolio are the most significant trends expected to impact the Bank’s liquidity in the near term.
The ALCO policy has established several measures of liquidity which are monitored monthly by the ALCO and quarterly by the Board of Directors. One 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. BankUnited’s liquidity is considered acceptable if the 30 day total liquidity ratio exceeds 100%. At September 30, 2017, BankUnited’s 30 day total liquidity ratio was 172%. 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. Forecasted deposit outflows, excluding certificate of deposits, are based on runoff rates derived from the most recent external core deposit analysis obtained by the Company. 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 September 30, 2017, BankUnited’s one year liquidity ratio was 158%. Additional measures of liquidity regularly monitored by the ALCO include the ratio of wholesale funding to total assets, a measure of available liquidity to volatile liabilities and the ratio of brokered deposits to total deposits. At September 30, 2017, BankUnited was within acceptable limits established by the ALCO and the Board of Directors for each of these measures.
As a holding company, BankUnited, Inc. is a corporation separate and apart from its banking subsidiary, and therefore, provides for its own liquidity. BankUnited, Inc.’s main sources of funds include management fees and dividends from the Bank, access to capital markets and, to a lesser extent, its own available for sale securities portfolio. There are regulatory limitations that 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
TheA principal component of the Company’s risk of loss arising from adverse changes in the fair value of financial instruments, or market risk, is interest rate risk, including the risk that assets and liabilities with similar re-pricing characteristics may not reprice at the same time or to the same degree. A primary objective of the Company’s asset/liability management
56


activities is to maximize net interest income, while maintaining acceptable levels of interest rate risk. The ALCO is responsible for establishing policies to limitmanage exposure to interest rate risk, and to ensure procedures are established to monitor compliance with these policies. The guidelinespolicies established by the ALCO are approved at least annually by the Board of Directors.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. Simulations are generated based on both static and dynamic balance sheet assumptions. Management continually reviews and refines its interest rate risk management process in response to changes in the interest rate environment, the economic climate and economic climate.observed customer behavior. Currently, our model projects a down 100, plus 100, plus 200 and plus 300 basis point change with rates increasing by the magnitude of theinterest rate ramp evenly over the next 12 months as well as flattening yield curve scenarios andrisk policy framework is based on modeling instantaneous rate shocks of downplus and minus 100, plus 100, plus 200, 300 and plus 300400 basis points.point shifts. We also model a variety of yield curve slope and dynamic balance sheet scenarios. We continually evaluate the scenarios being modeled with a view toward adapting them to changing economic conditions, expectations and trends.
The Company’s ALCO policy provides that net interest income sensitivity will be considered acceptable if decreases in forecast net interest income, based on a dynamic forecasted balance sheet, in specified rate shock scenarios 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. The following table illustrates the acceptable limits as defined by policy andpresents the impact on forecasted net interest income of down 100, plus 100, plus 200 and plus 300 basis pointcompared to a "most likely" scenario in parallel rate shock scenarios of plus 100, 200, 300 and 400 basis points at September 30, 2017March 31, 2022 and December 31, 2016:2021, as well as a minus 100 basis points scenario at March 31, 2022. At March 31, 2022, the most likely rate scenario incorporated a bear flattening yield curve and floored all indices at 0%. We did not apply the falling rate scenario at December 31, 2021 due to the low prevailing interest rate environment at that time.

Management also simulates changes in EVE in various interest rate environments.

We did not simulate decreases in interest rates greater than 100 basis points at September 30, 2017 due to the current low rate environment. The parameters established by the ALCO stipulate that the modeled decline in EVE is considered acceptable if the decline is less than 9%, 18% and 27% in plus or minus 100, plus or minus 200 and plus or minus 300 basis point scenarios, respectively. As of September 30, 2017, our simulation for the Company indicated percentage changes from base EVE of 1.7%, (3.6)%, (7.9)% and (12.7)% in down 100, plus 100, plus 200 and plus 300 basis point scenarios, respectively.December 31, 2021:
These measures fall within an acceptable level of interest rate risk per the policies established by the ALCO and the Board of Directors. In the event the models indicate an unacceptable level of risk, the Company could undertake a number of actions that would reduce this risk, including the sale or re-positioning of a portion of its available for sale investment portfolio, restructuring of borrowings, or the use of derivatives such as interest rate swaps and caps.

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 ratescash flows on variable rate borrowings suchliabilities and to changes in the fair value of fixed rate financial instruments, in each case caused by fluctuations in benchmark interest rates, as FHLB advances andwell as to manage duration of liabilities. These interest rate swaps are designated as cash flow hedging instruments. The fair value of thesederivative instruments designated as hedges is included in other assets and other liabilities in our consolidated balance sheets and changessheets. Changes in fair value of derivative instruments designated as cash flow hedges are reported in accumulated other comprehensive income. Changes in the fair value of derivative instruments designated as fair value hedges are recognized in earnings, as is the offsetting gain or loss on the hedged item. At September 30, 2017,March 31, 2022, outstanding interest rate swaps and caps designated as cash flow hedges had an aggregate notional amount of $2.0 billion. The aggregate fair value of$1.2 billion and outstanding interest rate swaps designated as cash flow

hedges included in other assets was $1.1 million and the aggregate fair value hedges had an aggregate notional amount of interest rate swaps designated as cash flow hedges included in other liabilities was $0.3$100 million.

Interest rate swaps and caps not designated as cash flow hedges had an aggregate notional amount of $2.3$3.4 billion at September 30, 2017. The aggregate fair value of these interest rate swaps and caps included in other assets was $27.3 million and the aggregate fair value included in other liabilities was $26.8 million.March 31, 2022. These interest rate swaps and caps were entered into as accommodations to certain of our commercial borrowers. To mitigate interest rate risk associated with these derivatives, the Company enters into offsetting derivative positions with primary dealers.

Impact of the COVID-19 Pandemic
A detailed discussion of the effects the COVID-19 pandemic had during 2021 on our Company has made no significant changes in its critical accounting policies and significant estimates from those disclosedappears in the 2016"Impact of the COVID-19 Pandemic and Our Response" section in the MD&A of the Company's 2021 Annual Reportreport on Form 10-K.
2021 and the first quarter of 2022 were characterized broadly by economic recovery as the U.S. economy emerged from the COVID-19 pandemic, evidenced by improving economic indicators such as GDP growth, unemployment and property valuations. The actual and expected impact of the pandemic on our financial condition and results of operations are expected to continue to lessen, although we are still closely monitoring emerging developments. Levels of criticized and classified assets remain elevated at March 31, 2022, when compared to pre-pandemic levels although they continue to trend downward. The ACL at March 31, 2022 still included certain qualitative loss factors related to the COVID-19 pandemic, and we continue to monitor the potential impact on expected credit losses of developments related to the pandemic. The composition of the balance sheet at March 31, 2022 and corresponding levels of net interest income reflect the opportunity cost of the decline in commercial loans and the increase in residential loans and securities that occurred over the course of the pandemic. Historically, commercial loans have generally tended to be higher yielding assets than residential loans and securities. During the first quarter of 2022, we welcomed our employees back to the office, adopting a hybrid work model for most non-branch employees. This model will likely continue to evolve over the near to medium term.

Evaluation of Disclosure Controls and Procedures
As of the end of the period covered by this Form 10-Q, we carried out an evaluation under the supervision and with the participation of our management, including the Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures as defined in Exchange Act Rules 13a-15(e) and 15d-15(e). Based upon that evaluation, the Chief Executive Officer and the Chief Financial Officer concluded that our disclosure controls and procedures were effective.
During the quarter ended September 30, 2017,March 31, 2022, there were no changes in the Company’sCompany's internal control over financial reporting, that materially affected, or are reasonably likely to materially affect, the Company’sCompany's internal control over financial reporting.

PART II.  OTHER INFORMATION
Item 1.   Legal Proceedings
 The Company is involved as plaintiff or defendant in various legal actions arising in the normal course of business. In the opinion of management, based upon currently available information and the advice of legal counsel, the likelihood is remote that the impact of these proceedings, either individually or in the aggregate, would be material to the Company’s consolidated financial position, results of operations or cash flows.
Item 1A.   Risk Factors
For a discussion of riskGeopolitical factors relating tosuch as the conflict between Russia and Ukraine or similar events could negatively impact our business please refer toand results of operations.
We are monitoring the factors discussed under “Part I-Item 1A - Risk Factors” inimpact of the conflict between Russia and Ukraine on our 2016 Form 10-K filed withbusiness. While we do not currently expect that the Securities and Exchange Commission on February 28, 2017, in addition to the following factor.
A significant portion of our loans are to borrowers whose businesses are located in or secured by properties located in the state of Florida, which was impacted by Hurricane Irma. In addition, the Bank hasconflict will have a limited number of customers and collateral properties located in areas of Texas that were impacted by Hurricane Harvey. The effects of Hurricanes Irma and Harvey and other adverse weather events may negatively affect our geographic markets or disrupt our operations, which could have an adversedirect material impact on our results of operations.
Our geographic markets in Florida and other coastal areas are susceptible to severe weather, including hurricanes, flooding and damaging winds. On September 10, 2017, Hurricane Irma made landfall in Florida as a Category 4 hurricane affecting some areas with significant flooding, wind damage and power outages. In addition, the Bank has a limited number of customers and collateral properties located in areas of Texas that were impacted by Hurricane Harvey during August, 2017. Weather events such as Hurricanes Irma and Harvey can disrupt our operations, result in damage to our facilities and negatively affect the local economies in which we operate. These events may lead to a decline in loan originations, reduce or destroy the value of collateral for our loans, particularly real estate, negatively impact the business, operations of our customers, and cause an increase in delinquencies, foreclosures and loan losses. These events may also lead to a decline in regional economic conditions and prospects in certain circumstances. Our businessfinancial condition or results of operations, may be adversely impacted by these and other negativecollateral effects of the geopolitical instability, such weather events.
We are currently inas the processimposition of assessing the impact of Hurricanes Irmasanctions against Russia and Harvey on our borrowers’ abilityRussia’s response to repay their obligations to the Banksuch sanctions, including retaliatory acts like cyber-attacks and on the value of underlying collateral properties. Although we currently believe the storms did not materially impact the abilitysanctions against other countries, or escalation or further spread of the substantial majority of our borrowers to repay their loans, our impact assessment is ongoing,conflict could adversely affect the global economy or domestic markets, including with respect to the impact on our loan originations, the value of properties securing our loans or the performance of our loans, the economic condition of our borrowers and their ability to timely repay their obligations, and the overall impacts on regional economic conditions and our business, operations and growth prospects in the affected market areas. As a result, it is premature to conclude with certainty as to the ultimate impact of these hurricanes on our level of loan losses, our business or the results of our operations. The Bank is generally named as a loss payee on hazard and flood insurance policies covering collateral properties and carries casualty and business interruption insurance. These policies could partially mitigate losses that the Bank may sustain due to the effects of these hurricanes; however, the timing and amount of any proceeds that we may recover from insurance policies is uncertain and may not be sufficient to adequately compensate us for losses that we experience due to these hurricanes and other natural disasters.ours.
