NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - UNAUDITED
September 30, 2017March 31, 2020






Note 1    Basis of Presentation and Summary of Significant Accounting Policies
BankUnited, Inc. is a national bank holding company with one wholly-owned subsidiary, BankUnited, collectively, the Company. BankUnited, a national banking association headquartered in Miami Lakes, Florida, provides a full range of banking and related services to individual and corporate customers through 9074 banking centers located in 1514 Florida counties and 65 banking centers located in the New York metropolitan area at September 30, 2017.March 31, 2020. 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, 20162019 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, 2020 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.
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 include the ALLL, the amount and timing of expected cash flows from covered assets and the FDIC indemnification asset,allowance for credit losses 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.
New Accounting Pronouncements Adopted During the Three Months Ended March 31, 2020
ASU No. 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. The amendments in this ASU simplified several aspects of the accounting for share-based payment transactions. The Company adopted this ASU in the first quarter of 2017. The amendment requiring the recognition of excess tax benefits and deficiencies as income tax benefit or expense 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 had no 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 classification of excess tax benefits and deficiencies with other income tax cash flows as operating activities and cash paid when directly withholding shares as financing activities in the accompanying consolidated statements of cash flows; the impact was not material. The Company elected to continue its practice of estimating the number of awards expected to vest in determining the amount of compensation cost to be recognized related to share based payment transactions.

September 30, 2017


ASU No. 2017-08, Receivables—Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities. 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 the requirements for assessing whether contingent call (put) options that can accelerate the payment of principal on debt instruments are clearly and closely related to their debt hosts. A company performing the assessment under these amendments 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. 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 estimate 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, FinancialFinancial Instruments - Credit Losses (Topic 326); Measurement of Credit Losses on Financial Instruments. The ASU, introducesalong with subsequent ASUs issued to clarify certain of its provisions, introduced new guidance which makesmade substantive changes to the accounting for credit losses. The ASU introducesintroduced 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-maturityHTM 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.forecasts, and is generally expected to result in earlier recognition of credit losses. The ASU also modifiesmodified certain provisions of the currentprevious OTTI model for available for saleAFS 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.securities. Credit losses on available for saleAFS debt securities will beare now limited to the difference between the security's amortized cost basis and its fair value.value, and should be recognized through an allowance for credit losses rather than as a direct reduction in amortized cost basis. The Company adopted this ASU in the first quarter of 2020 using the modified retrospective transition method for the CECL model and a prospective approach for the AFS debt security model. The Company recorded a cumulative-effect adjustment to retained earnings of $23.8 million, which included $4.8 million related to off -balance sheet credit exposures, on January 1, 2020. No cumulative-effect adjustment was recorded related to AFS debt securities upon adoption. The Company has elected to phase-in the initial impact of the adoption of ASC 326 for regulatory capital purposes, allowing the impact of adoption on regulatory capital to be delayed for two years, followed by a three-year transition period.

The ASU also provides optional relief for a simplifiedlimited period of time to ease the potential accounting modelburden associated with transitioning away from reference rates that are expected to be discontinued.

It is possible that the impact will be materialmaterial.
Updates to the Company's consolidatedSignificant Accounting Policies
Loans
The Company's loan portfolio contains 1-4 single family residential first mortgages, government insured residential mortgages, an insignificant amount of home equity loans and lines of credit and other consumer loans; multi-family, non-owner occupied commercial real estate, construction and land, owner-occupied commercial real estate and commercial and industrial loans, mortgage warehouse lines of credit and sales-type and direct financing leases. Loans are reported at amortized cost basis, net of the ACL.
Interest income is accrued based on the principal amount outstanding. Non-refundable loan origination fees, net of direct costs of originating or acquiring loans, as well as purchase premiums and discounts, are deferred and recognized as adjustments to yield over the contractual lives of the related loans using the level yield method.
Non-accrual loans
Commercial loans are placed on non-accrual status when (i) management has determined that full repayment of all contractual principal and interest is in doubt, or (ii) the loan is past due 90 days or more as to principal or interest unless the loan is well secured and in the process of collection. Residential and other consumer loans, other than government insured residential loans, are generally placed on non-accrual status when they are 90 days past due. When a loan is placed on non-accrual status, uncollected interest accrued is reversed and charged to interest income. Payments received on nonaccrual commercial loans are applied as a reduction of principal. Interest payments are recognized as income on a cash basis on nonaccrual residential loans. 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 and consumer loans are generally returned to accrual status when less than 90 days past due. Past due status of loans is determined based on the contractual next payment due date. Loans less than 30 days past due are reported as current.
Contractually delinquent government insured residential loans are not classified as non-accrual due to the nature of the guarantee. Contractually delinquent PCD loans are not classified as non-accrual as long as the Company has a reasonable expectation about amounts expected to be collected.
Troubled Debt Restructurings
In certain situations, due to economic or legal reasons related to a borrower's financial positiondifficulties, the Company may grant a concession to the borrower for other than an insignificant period of time that it would not otherwise consider. At that time, the related loan is classified as a TDR. The concessions granted may include rate reductions, principal forgiveness, payment forbearance, extensions of maturity at rates of interest below that commensurate with the risk profile of the loans, modification of payment terms and resultsother actions intended to minimize economic loss. A TDR is generally placed on non-accrual status at the time of operations.the modification unless the borrower was performing prior to the restructuring.

In August 2016,Under recently issued inter-agency and authoritative guidance and consistent with the FASB issued ASU No. 2016-15, StatementCARES Act, short-term (generally periods of Cash Flows (Topic 230): Classificationsix months or less) deferrals or modifications related to COVID-19 will typically not be categorized as TDRs.
Purchased Credit Deteriorated ("PCD") assets
PCD assets are acquired financial assets that, as of Certain Cash Receiptsthe date of acquisition, have experienced a more than insignificant deterioration in credit quality since origination. An assessment is conducted at acquisition to determine whether acquired financial assets meet the criteria to be classified as PCD assets. That assessment may be conducted at the individual asset level, or for a group of assets acquired together that have similar risk characteristics. At acquisition, the ACL related to PCD assets, representing the estimated amount of the UPB of the assets not expected to be collected, is added to the purchase price to determine the amortized cost basis and Cash Payments.any non-credit related discount or premium is allocated to the individual assets acquired. The amendments in this ASU provide guidance on eight specific cash flow classification issues wherenon-credit related discount or premium is accreted or amortized to interest income over the life of the related assets using the level yield method, as long as there has been diversity in practice. The guidanceis a reasonable expectation about amounts expected to be collected. Subsequent changes in the ASUamount of expected credit losses are recognized immediately by adjusting the ACL and reflecting the periodic changes as credit loss expense or reversal of credit loss expense.
Loans previously categorized as ACI loans were categorized as PCD loans on initial adoption of ASC 326. At adoption, an ACL was recognized and a corresponding adjustment was made to the assets' amortized cost basis. Prior to the adoption of ASC 326, ACI loans were accounted for on a pool basis. These pools were not maintained on adoption. The Company did not re-assess whether modifications to individual PCD loans previously accounted for in pools were TDRs at adoption.
Allowance for Credit Losses ("ACL")
AFS Debt Securities
The Company reviews its AFS debt securities for credit loss impairment at the individual security level on at least a quarterly basis. A security is impaired if its fair value is less than its amortized cost basis. A decline in fair value below amortized cost basis represents a credit loss impairment to the extent the Company does not expect to recover the amortized cost basis of the security. Impairment related to credit losses is recorded through the ACL to the extent fair value is less than the amortized cost basis. Declines in fair value that have not been recorded through the ACL are recorded through other comprehensive income, net of applicable taxes.
In assessing whether an impairment is credit loss related, the Company compares the present value of cash flows expected to be collected to the security's amortized cost basis. If the present value of cash flows expected to be collected is less than the amortized cost basis of the security, a credit loss exists and an ACL is recorded. The Company discounts expected cash flows at the effective interest rate implicit in the security at the purchase date, adjusted for expected prepayments. For floating rate securities, the Company uses the floating rate as it changes over the life of the security. In developing estimates about cash flows expected to be collected and determining whether a credit loss exists, the Company considers information about past events, current conditions and reasonable and supportable forecasts. Factors and information that the Company uses in making its assessments include, but are not necessarily limited to, the following:
The extent to which fair value is less than amortized cost;
Adverse conditions specifically related to the security, an industry or geographic area;
Changes in the financial condition of the issuer or underlying loan obligors;
The payment structure and remaining payment terms of the security, including levels of subordination or over-collateralization;
Failure of the issuer to make scheduled payments;
Changes in credit ratings;
Relevant market data;
Estimated prepayments, defaults, and the value and performance of underlying collateral at the individual security level.

The relative importance assigned to each of these factors varies depending on the facts and circumstances pertinent to the individual security being evaluated.
Timely payment of principal and interest on securities issued by the U.S. Government, U.S. government agencies and U.S. government sponsored entities is explicitly or implicitly guaranteed by the U. S. government. Therefore, the Company expects to recover the amortized cost basis of these securities.
If the Company intends to sell a security in an unrealized loss position, or it is more likely than not that the Company will be required to sell the security before recovery of its amortized cost basis, any allowance for credit losses will be written off and the amortized cost basis will be written down to the debt security’s fair value at the reporting date with any incremental impairment reported in earnings.
Historically, the Company has not experienced credit losses related to AFS securities or uncollectible interest on its AFS securities. However, AFS securities would be charged off to the extent that there was no reasonable expectation of recovery of amortized cost basis. AFS securities would be placed on non-accrual status if the Company did not reasonably expect to receive interest payments in the future and interest accrued would be reversed against interest income. Securities would be returned to accrual status only when collection of interest was reasonably assured.
Loans
The ACL is a valuation account that is deducted from the amortized cost basis of loans to present the net amount expected to be collected. The ACL is adjusted through the provision for credit losses to the amount of amortized cost basis not expected to be collected, or in the case of PCD loans, the amount of UPB not expected to be collected, at the balance sheet date. Amortized cost basis includes UPB, unamortized premiums or discounts and deferred fees and costs, net of amounts previously charged off.
The measurement of expected credit losses encompasses information about historical events, current conditions and reasonable and supportable forecasts. Determining the amount of the ACL is complex and requires extensive judgment by management about matters that are inherently uncertain. Re-evaluation of the ACL estimate in future periods, in light of changes in composition and characteristics of the loan portfolio, changes in the reasonable and supportable forecast and other factors then prevailing may result in material changes in the amount of the ACL and credit loss expense in those future periods.
Loans are charged off against the ACL in the period in which they are deemed uncollectible and recoveries are credited to the ACL when received. Expected recoveries on loans previously charged off, not to exceed the aggregate of amounts previously charged-off and expected to be charged-off, are included in the ACL estimate. For loans secured by residential real estate, an assessment of collateral value is made at no later than 120 days delinquency; any outstanding loan balance in excess of fair value less cost to sell is charged off at no later than 180 days delinquency. Additionally, any outstanding balance in excess of fair value of collateral less cost to sell is charged off (i) within 60 days of receipt of notification of filing from the bankruptcy court, (ii) within 60 days of determination of loss if all borrowers are deceased or (iii) within 90 days of discovery of fraudulent activity. Other consumer loans are typically charged off at 120 days delinquency. Commercial loans are charged off when, in management's judgment, they are considered to be uncollectible.
Expected credit losses are estimated on a collective basis for groups of loans that share similar risk characteristics. Factors that may be considered in aggregating loans for this purpose include but are not necessarily limited to, product or collateral type, industry, geography, internal risk rating, credit characteristics such as credit scores or collateral values, and historical or expected credit loss patterns. 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. Expected prepayments for commercial loans are generally estimated based on the Company's historical experience. For residential loans, expected prepayments are estimated using a model that incorporates industry prepayment data, calibrated to reflect the Company's experience. The contractual term excludes expected extensions, renewals, and modifications unless either of the following applies: management has a reasonable expectation at the reporting date that a TDR will be executed with an individual borrower or the extension or renewal options are included in the original or modified contract at the reporting date and are not unconditionally cancellable by the Company.
The Company has elected a 5-year reasonable and supportable forecast period, with mean reversion occurring within the credit loss models based on the economic inputs. The length of the reasonable and supportable forecast is evaluated at each reporting period and adjusted if deemed necessary.

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 are applied to estimated exposure at default, considering the term and payment structure of the loan, to generate estimates of expected loss at the loan level. For criticized or classified loans, PDs may be adjusted to industry benchmark PDs appropriate to the current risk rating if the most current financial information available is deemed not to be reflective of the borrowers' current financial condition. These loan level estimates are aggregated to generate a collective estimate for groups of loans that share common risk characteristics.
For certain less material portfolios including loans and leases to state and local government entities originated by Pinnacle, small balance commercial loans and consumer loans, the WARM method is used to estimate expected credit losses. For the Pinnacle portfolio, historical loss information is based on municipal historical default and recovery data, segmented by credit rating. For small balance commercial loans, historical loss information is based on the Company's historical loss experience over a five year period. For consumer loans, historical loss information is based on peer data; this portfolio subsegment is not significant. All loss estimates are conditioned as applicable on changes in current conditions and the reasonable and supportable economic forecast. Expected credit losses for mortgage warehouse lines of credit are estimated based primarily on the Company's historical loss experience, conditioned as applicable on changes in current conditions and the reasonable and supportable economic forecast. Generally, given the nature of these loans, losses would be expected to manifest within a very short time period after origination.
The Company expects to collect the amortized cost basis of government insured residential loans due to the nature of the government guarantee, so the quantitative ACL is zero for these loans.
Qualitative factors
Qualitative adjustments are made to the ACL when, based on management’s judgment, there are factors impacting expected credit losses not taken into account by the quantitative calculations. Potential qualitative adjustments are categorized as follows:
Economic factors, including material trends and developments that, in management's judgment, may not have been considered in the reasonable and supportable economic forecast;
Credit policy and staffing, including the nature and level of policy and procedural exceptions or changes in credit policy not reflected in quantitative results, changes in the quality of underwriting and portfolio management and staff and issues identified by credit review, internal audit or regulators that may not be reflected in quantitative results;
Concentrations, considering whether the quantitative estimate adequately accounts for concentration risk in the portfolio;
Model imprecision and model validation findings; and
Other factors not adequately considered in the quantitative estimate or other qualitative categories identified by management that may materially impact the amount of expected credit losses.
Collateral dependent loans
Collateral dependent loans are those for which the borrower is experiencing financial difficulty and repayment is expected to be most applicableprovided substantially through the operation or sale of the collateral. These loans do not typically share similar risk characteristics with other loans and expected credit losses are evaluated on an individual basis. Loans evaluated individually are not included in the collective evaluation. Estimates of expected credit losses for collateral dependent loans, whether or not foreclosure is probable, are based on the fair value of the collateral adjusted for selling costs when repayment depends on sale of the collateral.

For TDRs, or loans for which there is a reasonable expectation that a TDR will be executed, that are not collateral dependent, the credit loss estimate is determined by comparing the net present value of expected cash flows, discounted at the loan’s original effective interest rate, 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 theamortized cost basis of the natureloan.
Off-balance sheet credit exposures
Expected credit losses related to off-balance sheet credit exposures are estimated over the contractual period for which the Company is exposed to credit risk via a contractual obligation to extend credit, unless that obligation is unconditionally cancellable by the Company. Expected credit losses are estimated using essentially the same methodologies employed to estimate expected credit losses on the amortized cost basis of loans, taking into consideration the likelihood and amount of additional amounts expected to be funded over the terms of the losscommitments. The liability for credit losses on off-balance sheet credit exposures is presented within other liabilities on the consolidated balance sheets, distinct from the ACL. Adjustments to the liability are included in the provision for credit losses.
Accrued Interest Receivable
The Company has elected to present accrued interest receivable separate from the amortized cost basis of financial assets carried at amortized cost. The Company is applying the practical expedient provided in ASC 326 to exclude accrued interest receivable balances from tabular disclosures about financial assets carried at amortized cost and (3) cash proceeds from settlement of bank-owned life insurance policieshas elected not to be classified as cash flows from investing activities. Cash payments for premiumsestimate an ACL on bank-owned life insurance may be classified as cash flows for investing activities, operating activities or a combination thereof.

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.March 31, 2020 or other than temporarily impaired during the three months ended March 31, 2019. The Company does not intend to sell securities that are in significant unrealized loss positions at September 30, 2017March 31, 2020 and it is not more likely than not that the Company will 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, 2020, 314 securities available for sale were in unrealized loss positions. The amount of impairment related to 2029 of these securities was considered insignificant both individually and in the aggregate, totaling approximately $237$285 thousand and no further analysis with respect to these securities was considered necessary.
Unrealized losses at March 31, 2020 were primarily attributable to widening spreads, resulting in large part from market response to, and dislocation in the wake of, the emerging COVID-19 pandemic. 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, 2020 is described further described below:below.

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.

Private Label Securities:
None of the impaired securities had missed principal or interest payments or had been downgraded by a NRSRO at March 31, 2020. The Company performed an analysis comparing the present value of cash flows expected to be collected to the amortized cost basis of impaired securities. This analysis was based on a scenario that we believe to be generally more severe than our reasonable and supportable economic forecast at March 31, 2020, and incorporated assumptions about voluntary prepayment rates, collateral defaults, delinquencies, severity and other relevant factors as described further below. Our analysis also considered the structural characteristics of each security and the level of credit enhancement provided by that structure. Based on the results of this analysis, the Company expects to recover the entire amortized cost basis of its impaired AFS securities at March 31, 2020. No ACL was considered necessary at March 31, 2020.
Private label residential MBS and CMOs
At March 31, 2020, 40 private label residential MBS and CMOs were in unrealized loss positions. Our analysis of cash flows expected to be collected on these securities incorporated assumptions about collateral default rates, voluntary prepayment rates, loss severity, delinquencies and recovery lag. In developing those assumptions, we took into account collateral quality measures such as FICO, LTV, documentation, loan type, property type, agency availability criteria and performing status. We also regularly monitor sector data including home price appreciation, forbearance, delinquency and prepay trends as well as other economic data which would indicate further stress in the sector. Our March 31, 2020 analysis projected weighted average collateral losses for this category of 5% compared to weighted average credit support of 21%. 90% of impaired securities in this category were externally rated AAA, 6% were rated AA and one security representing 4% of the category was not externally rated; this security was internally rated investment grade.

Given the absence ofcash flows expected credit losses and management's ability and intent to hold the securities until recovery, the impairments were considered to be temporary.collected on these securities incorporated assumptions about collateral default rates, loss severity, and delinquencies, calibrated to take into account idiosyncratic risks associated with the underlying collateral. In developing those assumptions, we took into account each sector’s performance pre, during and post the 2008 financial crisis. We regularly engage with bond managers to monitor trends in underlying collateral including potential downgrades and subsequent cash flow diversions, liquidity, ratings migration, and any other relevant developments. Our March 31, 2020 analysis projected weighted average collateral losses for this category of 21% compared to weighted average credit support of 41%. 84% of impaired securities in this category were externally rated AAA, 13% were rated AA and 3% were rated A.

At March 31, 2020, 10 non-mortgage asset-backed securities were in unrealized loss positions. These securities are backed by student loan collateral. Our analysis of cash flows expected to be collected on these securities incorporated assumptions about collateral default rates, loss severity, delinquencies, voluntary prepayment rates and recovery lag. In developing those assumptions, we took into account collateral type, delineated by whether collateral consisted of loans to borrowers in school, refinancing, or a mixture.

Credit quality information
Loans other than ACI 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.

Credit quality information
Non-coveredThe increase in the ACL from January 1, 2020, the date of initial adoption of ASU 2016-13, to March 31, 2020 included approximately $93 million related to the change in the Company's reasonable and supportable economic forecast, in large part resulting from the emerging COVID-19 pandemic. The increase also reflected an increase in specific reserves of approximately $16 million, the majority of which related to the Bridge franchise finance portfolio. The credit quality of the loan portfolio has been and is likely to continue to be impacted by the developing COVID-19 crisis, its impact on the economy broadly and more specifically on the Company's individual borrowers. Significant uncertainty currently exists about the extent of this impact, and the impact is likely not fully reflected in the credit quality indicators disclosed below as of March 31, 2020, due to the recent emergence of the pandemic.

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 may result in deterioration of the repayment capacity of the borrower 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, 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 saleDisclosures Prescribed by Legacy GAAP (Before Adoption 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.ASU 2016-13) for Prior Periods

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.

Note 76 Derivatives and Hedging Activities
The Company uses interest rate swaps to manage interest rate risk related to liabilities that expose the Company to variability in cash flows due to changes in interest rates. The Company enters into LIBOR-based interest rate swaps that are designated as cash flow hedges with the objective of limiting the variability of interest payment cash flows resulting from changes in the benchmark interest rate LIBOR. ChangesThe Company also enters into LIBOR-based interest rate swaps designated as fair value hedges designed to hedge changes in the fair value of interestoutstanding fixed rate swaps designated as cash flow hedging instruments are reported in AOCI and subsequently reclassified into interest expenseborrowings caused by fluctuations in the same period in which the relatedbenchmark interest on the floating-rate debt obligations affects earnings.

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, 2020 and 2019, the impact on earnings, included in "other non-interest income" in the accompanying consolidated statements of income, 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 does not currently anticipate any losses from failure of interest rate derivative counterparties to honor their obligations.
The CME amended its rules effective January 2017 to legally characterizecharacterizes variation margin payments for centrally cleared derivatives as settlements of the derivatives' exposures rather than collateral. As a result, the variation margin payment and the related derivative instruments are considered a single unit of account for accounting and financial reporting purposes. The Company's clearing agent for interest rate derivative contracts centrally cleared through the CME settles the variation margin daily with the CME; therefore, those

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

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 on December 31st in equal tranches over three years.years for grants prior to 2019, and over four years for awards issued in 2019 and 2020. PSUs are initially granted based on a target value. The number of PSUs that ultimately vest at the end of a three-yearthe 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, or may be settled in cash at the Company's option. The share units will accumulate dividends declared on the Company's common stock from the date of grant to be paid subsequent to vesting.
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 thisthe majority of previous settlements being in cash, settlement, all RSUs and PSUs have been determined to be liability instruments and will beare 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

The618,306 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 for employees other than those eligible for the executive share-based awards discussed above provide for settlement through a combination of cash payments and unvested share awards following the end of the annual performance period. The dollar value of share awards to be granted is based on the achievement of performance criteria established in the incentive arrangements. The number of shares of common stock to be awarded is variable based on the closing price of the Company's stock on the date of grant; therefore, these awards are initially classified as liability instruments, with compensation cost recognized from the beginning of the performance period. TheAwards related to performance periods prior to 2019 vest over three years and awards related to the 2019 and 2020 performance periods vest in equal installments over a period of threefour years from the date of grant. These awards are included in the summary of activity related to unvested share awards above. The total liability for the incentive share awards for the 2020 performance period was $1.2$0.3 million at September 30, 2017.March 31, 2020. The total unrecognized compensation cost of $5.3$5.6 million for theseincentive share awards at September 30, 2017March 31, 2020 will be recognized over a weighted average remaining period of 3.254.76 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.
The 599,766 unvested share awards granted during the three months ended March 31, 2020, as discussed above, included 114,936 unvested share awards granted under the Company's annual incentive compensation arrangements based on the achievement of established performance criteria for the year ended December 31, 2019.

Note 109    Fair Value Measurements
Assets and liabilities measured at fair value on a recurring basis
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. Due to the natureThese 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 are determined using widely accepted discounted cash flow modeling techniques. These discounted cash flow models use projections of future cash payments and receipts that are discounted at mid-market rates. Observable inputs that may impact the valuation of these instruments include LIBOR swap rates and LIBOR forward yield curves. These fair value measurements are generally classified within level 2 of the fair value hierarchy.

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):

      Probability of default 0.13% - 4.04% (1.36%)
      Loss severity 15.00% - 75.00% (33.10%)
      Discount rate 1.88% - 7.43% (3.48%)

      Loss severity 15.00% - 95.00% (32.96%)
      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 
Unobservable
Input
 
Range (Weighted
Average)
  September 30, 2017   
Residential MSRs $18,006
 Discounted cash flow Prepayment rate 2.76% - 29.96% (12.88%)
      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 basis
Following is a description of the methodologies used to estimate the fair values of assets and liabilities that may be measured at fair value on a non-recurring basis, and the level within the fair value hierarchy in which those measurements are typically classified. 
Impaired loans, OREOand other repossessed assets—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 primarilya combination of observable and 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.

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

Included in the tables above are impaired taxi medallion loans with carrying values of $90.1 million and $39.6 million at September 30, 2017 and September 30, 2016, respectively, the majority of which were in New York City. Losses of $54.3 million and $10.2 million were recognized on impaired taxi medallion loans during the nine months ended September 30, 2017 and 2016, respectively.
Decreases in the value of medallions are largely driven by decreases in revenues generated from the medallions. Inputs that had the most significant impact on the valuation of New York City taxi medallions at September 30, 2017 are presented below:

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 1110     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

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. 
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.

Item 2.    Management's Discussion and Analysis of Financial Condition and Results of Operations 
The following discussion and analysis is intended to focus on significant matters impacting and changes in the financial condition and results of operations of the Company during the three and nine months ended September 30, 2017March 31, 2020 and should be read in conjunction with the consolidated financial statements and notes hereto included in this Quarterly Report on Form 10-Q and BKU's 20162019 Annual Report on Form 10-K for the year ended December 31, 20162019 (the "2016"2019 Annual Report on Form 10-K”).
Forward-Looking Statements

Words such as “anticipates,” “expects,” “intends,” “plans,” “believes,” “seeks,” “estimates”“estimates,” "future" and similar expressions identify forward-looking statements. These forward-looking statements are based on the historical performance of the Company or on the Company’s current plans, estimates and expectations. The inclusion of this forward-looking information should not be regarded as a representation by the Company that the future plans, estimates or expectations so contemplated will be achieved. Such forward-looking statements are subject to various risks and uncertainties and assumptions relating to the Company’s operations, financial results, financial condition, business prospects, growth strategy and liquidity.liquidity, including as impacted by the COVID-19 pandemic. If one or more of these or other risks or uncertainties materialize, or if the Company’s underlying assumptions prove to be incorrect, the Company’s actual results may vary materially from those indicated in these statements. A number of important factors could cause actual results to differ materially from those indicated by the forward-looking statements, including, but not limited to, the risk factors described in Part II, Item 1A of this Quarterly Report on Form 10- Q and in Part I, Item 1A of the 20162019 Annual Report on Form 10-K.10-K and any subsequent Quarterly Report on Form 10-Q or Current Report on Form


8-K. The Company does not undertake any obligation to publicly update or review any forward looking statement, whether as a result of new information, future developments or otherwise.
Impact of the COVID-19 Pandemic and Our Response
In March 2020, the World Health Organization declared novel coronavirus disease 2019 (COVID-19) as a global pandemic. The pandemic has resulted in governmental authorities implementing numerous measures attempting to contain the spread and impact of COVID-19 such as travel bans and restrictions, quarantines, shelter in place orders, and limitations on business activities, including in major markets in which the Company and its clients are located or do business. The COVID-19 pandemic, and governmental responses to the pandemic, have severely negatively impacted the global economy, disrupted global supply chains, lowered equity market valuations, created significant volatility and disruption in financial markets, and increased unemployment levels. This situation is evolving rapidly, and there is a high level of uncertainty about its future effects.
A summary of the effects the COVID-19 pandemic has had on our Company and of our expectations about how our Company may be impacted in the future follows. These matters are discussed in further detail throughout this Form 10Q.
Our results of operations and financial condition at and for the three months ended March 31, 2020 were impacted by the COVID-19 pandemic.
Deteriorating economic conditions and a worsening forward looking economic forecast led to a higher provision for credit losses and ACL; as a result, we reported a net loss for the quarter. There is significant uncertainty as to, and we are not currently able to predict, the impact of the COVID-19 crisis on future credit loss expense and future levels of the ACL, but they may be more volatile and may change materially from current levels.
Unrealized losses on our AFS securities increased substantially as a result of the market response to, and dislocation in the wake of, the emerging pandemic. The increase in unrealized losses negatively impacted total stockholders' equity and our tangible book value at March 31, 2020. Since these unrealized losses are recorded in AOCI, they did not impact our regulatory capital ratios. We currently expect to recover the amortized cost basis of our AFS securities.
Levels of criticized and classified assets increased at March 31, 2020 as a result of the COVID-19 pandemic. Additionally, a significant number of borrowers have requested relief in the form of temporary payment deferrals. Levels of criticized and classified assets are expected to increase further in the near term as a result of impacts of the pandemic on our borrowers. We re-assess the risk ratings of individual commercial credits as we review requests for and grant temporary payment relief, or as other information comes to our attention that would warrant a re-evaluation of the risk rating. At March 31, 2020, we had not experienced an increase in non-performing assets as a result of the pandemic. It is difficult to predict when, if, or to what extent levels of non-performing assets and delinquencies will increase as a result of the pandemic, although they may do so. Similarly, charge-offs may increase. These impacts may manifest in a delayed fashion due to the impact of temporary payment deferrals and various forms of government assistance that our borrowers may receive.
Our share price has been negatively impacted by the COVID-19 crisis.
Although we took significant measures to prepare for possible disruptions in liquidity, we have not experienced such disruptions to date and continue to have sufficient levels of available liquidity.
The pandemic has impacted our operations . Currently, approximately 97% of our non-branch employees are working remotely. We did not experience any significant operational difficulties, technology failures or outages, or customer service disruptions in our transition to a remote work environment. 76% of our branches remain open to serve customers via drive-through or lobby appointments, operating with reduced hours. Generally, branch locations without drive-through facilities are temporarily closed. We have focused on insuring that our technology systems and internal controls continue to operate effectively in a remote work environment. We have put mechanisms in place to allow us to evaluate all significant modifications to processes and procedures to insure continued effectiveness of our controls. We have not identified any instances in which controls have failed to operate effectively.
Customer demand for our products and services, particularly lending products, may be impacted by the impact of the pandemic on their businesses or by social distancing measures. Potential borrowers impacted by the pandemic may no longer meet our underwriting criteria. We expect loan production in many portfolio segments to be muted in the near term as a result of the pandemic.
In response to the pandemic, we have prioritized risk management and implemented a number of measures to support our customers and employees. Specifically, we have:
Activated our business continuity plan under the leadership of executive management.


Activated our contingency funding plan, enhancing daily monitoring and reporting of liquidity trends and deposit flows, and optimized same day available liquidity.
Established a weekly cadence of Board of Directors meetings.
Pro-actively reached out to all of our borrowers with total credit exposure of $5 million or more, and to all borrowers in certain high-risk segments to assess the potential impact of COVID-19.
Segregated certain segments of the loan portfolio for enhanced monitoring.
Enhanced our workout and recovery staffing and processes.
Enhanced our stress testing framework. Results of internal stress testing indicate that we have sufficient capital to withstand an increase in credit losses materially beyond levels currently expected, and to withstand a severe downturn.
Proactively reached out to our critical third party service providers and evaluated their ability to continue to provide support in the current environment. We have experienced no significant service disruptions.
Expanded certain employee benefits and launched a number of programs to keep our employees healthy and engaged.
Enhanced personal protective measures for employees working at our corporate locations.
Supported our clients through participating in the Small Business Administration’s PPP, and granting payment deferrals and fee waivers on a case-by-case basis.
Temporarily halted new residential foreclosure actions.
We remain confident in our long-term underlying strength and stability, and our ability to navigate these challenging conditions.
Overview
Quarterly Highlights
In evaluating our financial performance, we consider the level of and trends in net interest income, the net interest margin, 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 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 interest income increasedNon-interest bearing demand deposits grew by $19.5 million to $241.3$305 million for the quarterthree months ended September 30, 2017 from $221.7March 31, 2020, to 18.4% of total deposits at March 31, 2020 compared to 17.6% of total deposits at December 31, 2019 and 15.9% of total deposits at March 31, 2019. The majority of this growth was not directly related to line draws. Total deposits grew by $606 million for the three months ended March 31, 2020.
The average cost of total deposits declined to 1.36% for the three months ended March 31, 2020, from 1.48% for the immediately preceding quarter ended September 30, 2016. Interest income increased by $39.5 million, driven by increases inDecember 31, 2019 and 1.67% for the three months ended March 31, 2019.

from 1.71% at December 31, 2019, and declined further to 1.08% at April 17, 2020. This is a total decline of 0.63% since December 31, 2019, reflecting recent actions taken to reduce the cost of those liabilities.deposits.
The provision for credit losses totaled $125.4 million for the three months ended March 31, 2020, reflecting the application of the CECL methodology and encompassing management's estimate of the expected economic impact of the COVID-19 pandemic. For the ninethree months ended September 30, 2017,March 31, 2019, the Company recorded a provision for loan losses, under the incurred loss model, of $10.3 million.
The ACL represented our current estimate of expected lifetime credit losses from the loan portfolio and totaled $251 million, or 1.08% of total loans, at March 31, 2020. Upon initial adoption of CECL, at January 1, 2020, the ACL was 0.59% of total loans and at December 31, 2019, calculated under an incurred loss methodology, the ACL was 0.47% of total loans.
Pre-tax, pre-provision income totaled $85.0 million for the three months ended March 31, 2020 compared to $100.5 million for the three months ended March 31, 2019. Pre-tax, pre-provision income for the three months ended March 31, 2020 included a $5.0 million unrealized loss on marketable equity securities, resulting from the impact on markets of the COVID-19 crisis. Inclusive of this $5.0 million unrealized loss, loss on investment securities was $(3.5) million for the three months ended March 31, 2020 compared to a gain on investment securities of $5.8 million for the comparable quarter of the prior year, a negative variance of $9.2 million.

Stockholders' equity was impacted by a decline of $291.8 million in accumulated other comprehensive income for the ninethree months ended September 30, 2016.
Total interest earning assets increased by $613 million during the third quarter of 2017. Non-covered loans and leases, including equipment under operating lease, grew by $384 million during the quarter. For the nine months ended

Total deposits increased by $445 million for the quarter ended September 30, 2017March 31, 2020, attributed to $21.2 billion. For the nine months ended September 30, 2017, total deposits increased by $1.7 billion.
At September 30, 2017, 96.7% of the non-covered commercial loan portfolio was rated "pass" and substantially all of the non-covered residential portfolio was current. The ratio of non-performing, non-covered loans to total non-covered loans was 1.00% and the ratio of non-performing, non-covered assets to total assets was 0.69% at September 30, 2017. Non-performing taxi medallion loans comprised 0.60% of total non-covered loans and 0.41% of total assets at September 30, 2017.

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 impact 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 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 areas for the period September 10, 2017 through September 30, 2017. In addition, certain residential mortgage and SBA loan customers impacted by the storm may be eligible for assistance in the form of temporary payment deferrals. Waived and refunded fees were not significant.
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.share.
Results of Operations
Net Interest Income
Net interest income is the difference between interest earned on interest earning assets and interest incurred on interest bearing liabilities and is the primary driver of core earnings. Net interest income is impacted by the 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, 2017 compared to three months ended September 30, 2016
Net interest income, calculated on a tax-equivalent basis, was $252.0$185.2 million for the three months ended September 30, 2017March 31, 2020 compared to $230.5$196.5 million for the three months ended September 30, 2016, an increaseMarch 31, 2019, a decrease of $21.5$11.3 million. The increasedecrease in net interest income was comprised of an increasea decrease in tax-equivalent interest income of $41.5$28.7 million offset by an increaseand a decrease in interest expense of $19.9 million.$17.4 million for the three months ended March 31, 2020, compared to the three months ended March 31, 2019.
The increasedecrease in tax-equivalent interest income was comprised primarily of (i) a $27.9 million increasedecrease in interest income from loans and a $12.8 million increase in interest income from investment securities.

Increased interest income from loans was attributable to a $1.7 billion 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:
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 $74.5of $6.9 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.
The components of the increase in interest expense for the three months ended September 30, 2017 asMarch 31, 2020 compared to the three months ended September 30, 2016 wereMarch 31, 2019; and (ii) a $15.0 million increasedecrease in interest expense on deposits and a $5.0income from investment securities of $20.7 million increase in interest expense on FHLB advances.
The increase in interest expense on deposits was attributable to an increase of $2.5 billion in average interest bearing deposits and an increase in the average cost of interest bearing deposits of 0.22% to 1.02% for the three months ended September 30, 2017 from 0.80% forMarch 31, 2020 compared to the three months ended September 30, 2016. These cost increases were generally driven by growth of deposits in competitive markets and a rising market interest rate environment.March 31, 2019.
The increase in interest expense on FHLB advances reflected an increase in the average cost of advances of 0.45% to 1.37% for the three months ended September 30, 2017 from 0.92% for the three months ended September 30, 2016. The increase in cost was driven by increased market rates and to a lesser extent, an extension of maturities through interest rate swaps.

The net interest margin, calculated on a tax-equivalent basis, was 2.35% for the three months ended September 30, 2017 was 3.62% asMarch 31, 2020, compared to 3.69%2.41% for the immediately preceding quarter ended December 31, 2019 and 2.54% for the three months ended September 30, 2016. TheMarch 31, 2019. Both yields on interest rate spread decreased to 3.43%earning assets and the cost of interest bearing liabilities declined for the three months ended September 30, 2017 from 3.53%March 31, 2020 as compared to the immediately preceding quarter and to the three months ended March 31, 2019; however, the repricing of interest bearing liabilities, particularly deposits, lagged the repricing of interest earning assets.

The declinesMarch 31, 2020 compared to the three months ended March 31, 2019 was attributable to a decrease in net interest margin and interest rate spread resulted primarily from the cost of interest-bearing liabilities increasing by more than the yield, on interest earning assets. This difference was driven primarily by the decline in covered loans as a percentage of total loans. Future trends in the net interest margin will be impacted by changes in market interest rates, including changes in the shape of the yield curve, by the mix of interest earning assets, including the decline in covered loans as a percentage of total loans, and by the Company's ability to manage the cost of funds while growing deposits in competitive markets.
Nine months ended September 30, 2017 compared to nine months ended September 30, 2016
Net interest income, calculated on a tax-equivalent basis, 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,partially offset by an increase in interest expense of $42.0 million.
The increase in tax-equivalent interest income was comprised primarily of an $81.9$876 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 attributable 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 contributing to the relatively steady yield on loans included:
Although the yield on non-covered loans increased 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 percentage of the portfolio for the nine months ended September 30, 2017 than for the corresponding period in 2016. Non-covered loans represented 97.2% of the average balance 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.loans. The tax-equivalent yield on those loans increaseddecreased to 53.54%4.18% for the ninethree months ended September 30, 2017March 31, 2020, from 40.48%4.50% for the ninethree months ended September 30, 2016.March 31, 2019. The most significant factor contributing to this decrease in yield was the impact of decreases in benchmark interest rates.
The average balance of investment securities increaseddecreased by $1.0 billion$412.9 million for the ninethree months ended September 30, 2017 fromMarch 31, 2020 compared to the ninethree months ended September 30, 2016 while theMarch 31, 2019. The tax-equivalent yield on investment securities decreased to 2.81% for the three months ended March 31, 2020 from 3.64% for the three months ended March 31, 2019. The most significant factors contributing to the decrease in yield were the impact of decreases in benchmark interest rates and, to a lesser extent, increased to 3.07% from 2.82%.prepayment speeds. This decline is reflective of the short duration of the investment portfolio in a falling rate environment.
The primary components of the increasedecrease in interest expense for the ninethree months ended September 30, 2017 asMarch 31, 2020 compared to the ninethree months ended September 30, 2016March 31, 2019 were a $33.7decrease of $14.6 million increase in interest expense on deposits and an $8.3a decrease of $2.3 million increase in interest expense on FHLB advances. The decreases were primarily the result of decreases in the cost of interest bearing liabilities.
The increasedecrease in interest expense on deposits was attributable primarily to an increase of $2.4 billion in average interest bearing deposits and an increasea decrease in the average cost of interest bearing deposits of 0.16%0.31% to 0.94%1.66% for the ninethree months ended September 30, 2017March 31, 2020 from 0.78%1.97% for the ninethree months ended September 30, 2016. March 31, 2019. This decrease was generally driven by decreases in market interest rates in 2019.
The increasedecrease in interest expense on FHLB advances was primarilyresulted from a result of an increasedecrease in the average cost of advances of 0.19%0.09% 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 those2.29% for the three month periods discussed above.months ended March 31, 2020 from 2.38% for the three months ended March 31, 2019. The decrease in cost was driven primarily by decreases in benchmark interest rates. The impact of declines in benchmark rates on the cost of FHLB advances is muted to an extent by the impact of cash flow hedges put in place to manage overall interest sensitivity of the balance sheet. The average balance of advances decreased by $245 million for the three months ended March 31, 2020 compared to the three months ended March 31, 2019.
TheFor the three months ended March 31, 2020, the increase in average non-interest bearing demand deposits as a percentage of total deposits positively impacted the net interest margin.
While we currently expect the net interest margin calculatedto expand in the second quarter of 2020, primarily as a result of an expected decline in deposit costs, over a longer time horizon, a persistent flat yield curve and a potential increase in non-performing loans attributable to the impact of the COVID-19 pandemic could put pressure on a tax-equivalent basis, for the nine months ended September 30, 2017 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 declines in net interest margin and interest rate spread resulted primarily from the factors discussed above.margin.
Provision for LoanCredit Losses
The provision for loancredit losses is the amount of expense that, based on our judgment, isa charge to earnings required to maintain the ALLLACL at an adequatea level to absorb probableconsistent with management’s estimate of expected credit losses inherent in the loan portfolioon financial assets carried at amortized cost at the balance sheet datedate. The amount of the provision is impacted by changes in management's reasonable and that,supportable economic forecast, loan originations and runoff, changes in management’s judgment, is appropriate under GAAP.portfolio mix, risk rating migration and portfolio seasoning, the level of charge-offs, changes in specific reserves, changes in expected prepayment speeds and other assumptions. The provision for credit losses also includes an amount related to off-balance sheet credit exposures. 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 for 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.

ACL.
For the three months ended September 30, 2017 and 2016, we recorded provisionsMarch 31, 2020, the provision for (recovery of) loancredit losses of $0.3totaled $125.4 million, and $(0.4)which included $3.6 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.off-balance sheet credit exposures. 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) loancredit 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 million for the three months ended September 30, 2017March 31, 2020 reflected the implementation of the CECL methodology and 2016, respectively. Non-interest incomemanagement's estimate of the expected negative economic impact of the COVID-19 pandemic. The provision included approximately $93 million related to changes in the economic forecast since the initial adoption of CECL on January 1, 2020 and was $111.4impacted by an increase of approximately $16 million and $77.1 million in specific reserves during the quarter, which we believe was also exacerbated by the COVID-19 pandemic. Most of the increase in specific reserves related to credits in the Bridge franchise finance portfolio segment. The provision for credit losses, excluding the portion related to off-balance sheet credit exposures, was 0.53% of average loans for the ninethree months ended September 30, 2017 and 2016, respectively. A significant portionMarch 31, 2020.


For the three months ended March 31, 2019, the Company recorded a provision for loan losses, under the incurred loss methodology, of our non-interest income has historically related$10.3 million.

The consolidated financial statements reflect the impact of gains or losses arising from transactions in the covered assets. 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 related to the following types of transactions 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 statementsloans 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 of 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 additions 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.

Excluding amortization of the FDIC indemnification asset, non-interest expense as a percentage of average assets was 1.5% and 1.6% for the three and nine months ended September 30, 2017, respectively, and 1.6% and 1.7% for the three and nine months ended September 30, 2016, respectively. The more significant changes in the components of non-interest expense are discussed below.benefits
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 declined by $6.3 million for the three and nine months ended September 30, 2017 increased by $3.2 million and $12.0 millionMarch 31, 2020 as compared to the corresponding periodsthree months ended March 31, 2019, primarily due to a reduction in 2016. The increasesheadcount and a decrease in equity based compensation expense related to the impact of a declining stock price on liability-classified awards.
Professional fees
Professional fees decreased by $4.7 million for the three and nine months ended September 30, 2017 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. As 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 change 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.
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 DecemberMarch 31, 2016. The entire balance of the FDIC indemnification asset relates

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,2020 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 comparedMarch 31, 2019. The decrease was primarily due to the corresponding periodsconsulting services in 2016. These increases generally correspond2019 related to the growth in the portfolio of equipment under operating lease.our BankUnited 2.0 initiative.
Other non-interest expense
The most significant components of other non-interest expense are advertising, promotion and promotion,business development, costs related to lending activities, loan servicing and deposit generation, OREOinsurance, expenses related expenses, insurance,to workouts and foreclosures, regulatory examination assessments, travel and general office expense. Other non-interest expense for the three months ended September 30, 2017 includes $0.6

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 rateSee Note 5 to the statutory federal tax rate of 35.0% included the effect of stateconsolidated financial statements for information about income taxes and the impact of income not subject to federal tax for each of the periods presented.

This increase was driven by a $2.1 billion$876 million increase in the average balance of outstanding loans, andoffset by a $1.0 billion increase$413 million decrease 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.

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, GNMA securities, SBA securities and U.S. Government agencyAgency MBS. 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 rental real estate-backed securities and non-mortgage asset-backed securities that, while somewhat less liquid, provide us with attractive yields. Relatively short effective portfolio duration helps mitigate interest rate risk 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, 2020 was 4.9 years and the4.3 years. The effective duration of the investment portfolio as of March 31, 2020 was 1.7 years. 1.3 years . The model results are based on assumptions that may differ from actual results.

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-temporarilycredit loss impaired at September 30, 2017, or during the three and nine months then ended.

We do not intend to sell securities in significant unrealized loss positions at September 30, 2017.March 31, 2020. 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. The severity of impairment of individual securities in the portfolio is generally not material. Unrealized losses in the portfoliobasis, which may be at September 30, 2017 were primarily attributable to an increase in market interest rates subsequent to the date the securities were acquired.maturity.
The timely repaymentpayment of principal and interest on securities issued by the U.S. Treasury,government, U.S. Government agencygovernment agencies and U.S. government sponsored enterprise securities in unrealized loss positionsenterprises is explicitly or implicitly guaranteed by the full faith and credit of the U.S. Government. Management performed projected cash flow analysesAs such, there is an assumption of zero credit loss and the Company expects to recover the entire amortized cost basis of these securities.
None of our impaired private label residential MBSsecurities had missed principal or interest payments or had been downgraded by a NRSRO at March 31, 2020. The Company performed an analysis comparing the present value of cash flows expected to be collected to the amortized cost basis of impaired securities. This analysis was based on a scenario that we believe to be generally


more severe than our reasonable and CMOs, private label commercial MBSsupportable economic forecast at March 31, 2020, and non-mortgage asset-backed securities in unrealized loss positions, incorporating CUSIP levelincorporated assumptions consistent withabout voluntary prepayment rates, collateral defaults, delinquencies, severity and other relevant factors. Our analysis also considered the collateralstructural characteristics of each security including collateral default rate, voluntary prepayment rate, severity and delinquency assumptions.the level of credit enhancement provided by that structure. Based on the results of this analysis, nowe expect to recover the entire amortized cost basis of the impaired private label AFS securities. Further information about the portfolio segments evidencing the largest unrealized losses at March 31, 2020, the CMBS and CLO portfolio segments, follows.
For private label CMBS, our analysis of cash flows expected to be collected incorporated assumptions about collateral default rates, voluntary prepayment rates, loss severity, delinquencies and recovery lag. In developing those assumptions, we took into account collateral quality and type, loan size, loan purpose and other qualitative factors. We also regularly monitor collateral watchlisted, bankruptcy data, special servicing trends, delinquency and other economic data which would indicate further stress in the sector. 
For CLOs, our analysis of cash flows expected to be collected incorporated assumptions about collateral default rates, loss severity, and delinquencies, calibrated to take into account idiosyncratic risks associated with the underlying collateral. In developing those assumptions, we took into account each sector’s performance pre, during and post the 2008 financial crisis. We regularly engage with bond managers to monitor trends in underlying collateral including potential downgrades and subsequent cash flow diversions, liquidity, ratings migration, and any other relevant developments.

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 establishedhave 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.source. We have established acceptable percentage deviations from the price provided by the initial pricing source. If deviations fall outside the established parameters, we will obtain and evaluate more detailed information about the assumptions and inputs used by each pricing source or, if considered necessary, employ an additional valuation specialistsource 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, 2017We are closely monitoring the impact of the COVID-19 pandemic on markets, and December 31, 2016, 1.0%on our ability to price securities in our portfolio. While we have observed increased volatility, we believe the fiscal and 2.1%, respectively,monetary response to the crisis has been effective in supporting liquidity and stabilizing markets. To date, circumstances have not led to a change in the categorization of our investment securities were classifiedfair value estimates 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.

Loans secured byThe Company’s commercial real estate typically have shorter repayment periods and re-price more frequently than 1-4 single family residential loans but may have longer terms and re-price less frequently than commercial and industrial loans. The Company’s underwriting standards generally provide for loan terms of five to tenseven years, with amortization schedules of no more than thirty years. LTV ratios are typically limited to no more than 80%75%. Owner-occupied commercial real estate loans typically have risk profiles more closely aligned with that of commercial and industrial loans than with other types of commercial real estate loans. Construction and land loans, included by property type in the table above, represented only 1.3%1% of the total loan portfolio at September 30, 2017.March 31, 2020. Construction and land loans are generally made for projects expected to stabilize within eighteen months of completion

in sub-markets with strong fundamentals and, to a lesser extent, for-sale residential projects to experienced developers with a strong cushion between market prices and loan basis. 79% of the commercial real estate portfolio had LTVs less than 65% at March 31, 2020.
The New York legislature has enacted a number of rent regulation reform measures that generally have the impact of limiting landlords' ability to increase rents on stabilized units and to convert stabilized units to market rate units. The following table presents the amount of loans secured by New York multi-family properties in which some or all units are rent regulated at March 31, 2020 (in thousands):
Loans secured by stabilized properties subject to rent regulation$1,036,885
Loans secured by non-stabilized properties subject to rent regulation34,751
 $1,071,636
We believe loans secured by non-stabilized properties may present a heightened level of risk as these loans were underwritten to expected cash flows upon stabilization; those expected cash flows may be impacted by the recent rent regulation reform measures.
The following tables present the distribution of stabilized rent-regulated multi-family loans, by DSCR and LTV at March 31, 2020 (in thousands):

The LTVs in the table above are based on the most recent appraisal obtained, which may not be fully reflective of changes in valuations that may result from the impact of the rent regulation reforms. Loans with DSCR less than 1.11 may be those with temporary vacancies or those for which expenses, particularly real estate taxes, have increased more rapidly than rents. All of the loans included in the tables above are current and performing.

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. WeIn response to the COVID-19 pandemic, we have an experienced resolution team in place for covered residential mortgage loans,further enhanced our workout and have implemented outsourcing arrangements with industry leading firms in certain areas such as OREO resolution. 
recovery staffing and processes. Loan performance is monitored by our credit administration 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 credit review department. The Company utilizes a 13 grade internal asset risk classification system as part of its efforts to monitor and maintain commercial asset quality. Loans exhibiting potential credit weaknesses that deserve management’s close attention and, that if left uncorrected, may result in deterioration of the repayment capacity of the borrower are categorized as special mention. These borrowers may exhibit negative financial trends or erratic financial performance, strained liquidity, marginal collateral coverage, declining industry trends or weak management. Loans with well-defined credit weaknesses that may result in a loss if the deficiencies are not corrected are assigned a risk rating of substandard. These borrowers may exhibit payment defaults, inadequate cash flows, operating losses, increasing balance sheet leverage, project cost overruns, unreasonable construction delays, exhausted interest reserves, declining collateral values, frequent overdrafts or past due real estate taxes. Loans with weaknesses so severe that collection in full is highly questionable or improbable, but because of certain reasonably specific pending factors have not been charged off, are assigned an internal risk rating of doubtful.
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 charts below present trends in criticized and classified loans from December 31, 2019 to March 31, 2020 (in millions):
criticclassified1a03.jpg
Criticized and classified loans increased by $269 million, to 3.1% of total loans at March 31, 2020 from 1.9% of total loans at December 31, 2019. The increase was in the special mention and substandard accruing categories. As reflected in the charts above, the majority of the increase was in the franchise finance portfolio. Approximately 90% of the downgrades in franchise finance during the quarter were directly related to the COVID-19 pandemic. Given the emerging nature of and uncertainty surrounding the COVID-19 crisis, we will likely see further impacts on the risk rating distribution of the loan portfolio in the future.
Potential Problem Loans
Potential problem loans have been identified by management as those commercial loans included in the "substandard accruing" risk rating category. 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.

Retail Exposure in the CRE Portfolio
The predominant collateral type supporting this segment is both anchored and un-anchored retail centers, including some mixed-use properties with a significant retail component. We estimate that approximately 60% of this sub-segment is supported by what we consider to be essential or moderately essential businesses in the context of the pandemic. We have no significant large shopping mall or "big box" exposure. The weighted average LTV for this sub-segment is 57.5% and 84% has LTVs less than 65%, based on the most recently available information.
Retail Exposure in the C&I Portfolio
This is a well-diversified sub-segment by industry. The largest exposure is to gas stations, generally with convenience stores, representing $97 million, or 28% of the sub-segment. 63% of loans in this sub-segment are collateralized by owner-occupied real estate.

The quick service restaurant sector broadly has been experiencing margin pressure due to rising labor costs and industrial loan portfolio includes exposure to taxi medallion finance of $121 million at September 30, 2017.

Concepts that have adopted digital ordering, delivery, take-out and drive through models may be better positioned in light of repayment,COVID-19 related social distancing measures. Fitness concepts, which have declined significantly in recent years due to competitive developments inbeen 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 TDRsbetter performing group in this portfolio segmentsub-segment may now be under increased stress due to continuesocial distancing measures arising from the pandemic.

The Company's energy exposure in the loan portfolio is not material; approximately 84% 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 priormarine transport equipment.

The presentMarch 31, 2020. 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 paymentstime off-lease, criticized or classified status, or management's intention to sell the asset at an amount potentially below its carrying value. At March 31, 2020, there were 13 operating leases for which a triggering event was met.

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.
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 utilizing credit administration infrastructure, processes and procedures similar to those used to manage and monitor credit risk in the commercial loan portfolio. We also mitigate credit risk in this portfolio by leasing only to high credit quality obligors.
We expect our operating lease portfolio to continue to grow, 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 equipment or to the ongoing operations of lessees from Hurricanes Irma and Harvey.
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

Covered Loans
At September 30, 2017, residential ACI loans totaled $476 millionNote 4 to the consolidated financial statements presents additional information about key credit quality indicators and residential non-ACI loans totaled $62 million, including premiums, discounts and deferred fees and costs. All of these loans are covered under the Single Family Shared-Loss Agreement.
Covered residential loans were placed into homogenous pools at the timedelinquency status 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, the recorded investment in ACI 1-4 single family residential loans totaled $470.3 million; $34.2 million or 7.3% of these loans were delinquent by 30 days or more and $17.6 million or 3.7% were delinquent by 90 days or more.
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.

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 and placed on non-accrual status, (ii) accruing loans that are more than 90 days contractually past due as to interest or principal, excluding ACIgovernment 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.

The carrying value of ACIsuch loans contractually delinquent by more than 90 days but on which income was still being recognized was $18$623 million and $16$529 million at September 30, 2017March 31, 2020 and December 31, 2016,2019, respectively. The increase of ACL to total loans and ACL to non-performing loans ratios at March 31, 2020 from December 31, 2019 is attributable to the adoption of CECL effective January 1, 2020 and the impact on the provision for credit losses recorded during the first quarter of 2020 resulting from changes to our economic forecast as a result of COVID-19.
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 of interest is due and unpaid.past due. When a loan is placed on non-accrual status, uncollected interest accrued is reversed and charged to interest income. Commercial loans are returned to accrual status only after all past due principal and interest has been collected and full repayment of remaining contractual principal and interest is reasonably assured. Residential loans are generally returned to accrual status when less than 90 days 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, 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. Included in TDRs are residential loans to borrowers who have not reaffirmed their debt discharged in Chapter 7 bankruptcy.
Under recently issued inter-agency and authoritative guidance and consistent with the CARES Act, short-term (generally periods of six months or less) deferrals or modifications related to COVID-19 will typically not be categorized as TDRs. See the section below entitled "Loss Mitigation Strategies - Impacts of the COVID-19 pandemic" for further discussion.

See Note 4 to the "substandard accruing" risk rating category. 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 $185 million at September 30, 2017, substantially all of which were current as to principal and interest at September 30, 2017.consolidated financial statements for additional information about TDRs.
Loss Mitigation Strategies
Criticized or classified commercial loans in excess of certain thresholds are reviewed quarterly by the Criticized Asset Committee, which determinesevaluates the appropriate strategy for collection to mitigate the amount of credit losses. 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;substandard, impaired loans on non-accrual status;status, loans modified as TDRs; taxi medallion loans;TDRs or 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 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.
Impacts of the COVID-19 pandemic
In response to the COVID-19 pandemic and its potential economic impact to our customers, we implemented a short-term program that complies with the CARES Act under which we are providing temporary relief 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, 2016,2019. For commercial borrowers, this relief typically allows for deferrals of principal and/or interest payments for 90 days, which may be extended, again on a case by case basis, for an additional 90 days, for a maximum of 180 days on a cumulative and successive basis. The deferred payments along with interest accrued during the deferral period are due and payable on the maturity date. For residential borrowers, relief typically takes the form of 90 day payment deferrals, with deferred payments due at the end of the 90 day period. At the end of the 90 day deferral period, residential borrowers may either (i) make all payments due, (ii) be granted an additional deferral period or (iii) enter into a modification or repayment plan. We have also temporarily suspended new residential foreclosure actions.
Through April 20, 2020, we offered loan modifications under the HAMP programhave granted temporary deferrals to eligible borrowers as summarized in the residential portfolio. HAMP is a uniform loantable below (in millions):

The substantial majority of these deferrals were not implemented until after March 31, 2020.
Under recently issued inter-agency guidance and consistent with the CARES Act, these deferrals or modifications will generally not be categorized as TDRs. Loans subject to these temporary deferrals or modifications, if in compliance with the contractual terms of the deferral or modification process that provides eligible borrowers with sustainable monthly mortgage payments equalagreements, will typically not be reported as past due or classified as non-accrual during the deferral period.

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 forecasts. Determining the amount of the ACL is complex


and requires extensive judgment by nature, highly complex and subjective. Future eventsmanagement about matters that are inherently uncertain could result in material changes to theuncertain. There is currently a high level of uncertainty around the ALLL. General economic conditions including but not limited to unemployment rates,impact the levelCOVID-19 crisis will have on the economy broadly, and on our borrowers specifically. In light of business investment and growth, real estate values, vacancy rates and rental ratesthis uncertainty, we believe it is possible that the ACL estimate could change, potentially materially, in future periods. Changes in the ACL may result from changes in our primary market areas,economic forecast, changes in loan portfolio composition, and circumstances not currently known to us that may impact the levelfinancial condition and operations of interest rates,our borrowers, among other factors.
For the substantial majority of the loan portfolio, expected losses are estimated using econometric models that employ a factor based methodology to estimate PD and a variety of other factors that affect the ability of borrowers’ businessesLGD. Projected PDs and LGDs are applied to estimated exposure at default to generate cash flows sufficientestimates of expected loss at the loan level. These loan level estimates are aggregated by portfolio segment and loan class to service their debts will impact the future performancegenerate a collective estimate for groups of the portfolio. 
New and non-ACILoans
Residential and other consumer
Dueloans that share common risk characteristics. Qualitative adjustments may also be applied to the lack of similarity between the risk characteristics of new loans and covered loans in the residential and home equity portfolios,incorporate factors that 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 loanshave been adequately considered in the Bank’s portfolioquantitative estimate. For loans that do not share similar risk characteristics with other loans such as collateral dependent loans and the geographic diversity in the new purchased residential portfolio, we determined that prime residential mortgage securitizations provide an appropriate proxy for incurredTDRs, expected credit losses in this portfolio class. A peer group 16-quarter average net charge-off rate 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 portfolios are not significant components of the overall loan portfolio.
Basedestimated on an analysis of historical performance, OREO and short saleindividual basis. Expected credit losses recent trending data and other internal and external factors, we have concluded that historical performance by portfolio class isare estimated over 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 amountcontractual term 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 allowanceadjusted for non-ACI residential loans will result in a corresponding increase or decrease in the FDIC indemnification asset. expected prepayments.
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 equalSee Note 1 to the amount by which each loan exceeded 85% of the estimated value, in recognition of the continued declining trend in cash flowsconsolidated financial statements for more detailed information about our ACL methodology 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.
Since the majority of the new commercial loan portfolio is not yet seasoned enough to exhibit a loss trend, the quantitative loss factors 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 Factors
Qualitative adjustments are made to the ALLL when, based on management’s judgment, there are internal or external factors impacting probable incurred 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;  
Changes in the nature of the portfolio and terms of the loans, specifically including the volume and nature of policy and procedural exceptions;
Portfolio growth trends;  
Changes in lending policies 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 identified by management that may impact the level of losses inherent in the portfolio, including but not limited to competition and legal and regulatory considerations.

For ACI loans, a valuation allowance is established when periodic evaluations of expected cash flows reflect a deterioration resulting from credit related factors from 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 performance 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, based on Case-Shiller Home Price Indices 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 on our analysis, no ALLL related to ACI commercial loans was recorded at September 30, 2017 or December 31, 2016.

The following chart depicts the changes in the ACL from December 31, 2019 to March 31, 2020 (in millions):
aclwaterfall.jpg
The ALLLincrease in the ACL from January 1, 2020, the date of initial adoption of ASC 326, to March 31, 2020 was primarily due to changes in our reasonable and supportable forecast, in large part resulting from the emerging COVID-19 pandemic. The Company based its reasonable and supportable economic forecast used in estimating the ACL at September 30, 2017March 31, 2020 on Moody's March Mid-Cycle Baseline forecast dated March 27, 2020. This forecast featured a peak-to-trough drop of approximately 20% in real GDP and a national unemployment rate approaching 9% in the second quarter of 2020, the VIX approaching 60 and year-over-year declines in the S&P 500 index reaching a low of near 30%. The forecast contemplated a recovery beginning in the second half of 2020 with unemployment remaining elevated into 2023. The econometric models we use to estimate


expected credit losses ingest a wide array of national, regional and MSA level economic variables and data points. Some of the more impactful include unemployment rates, a market volatility index, a stock price index, real GDP, a variety of interest rates and spreads, HPI, and commercial real estate forecast data.
The ACL for residential and other consumer loans decreased from January 1, 2020 to March 31,2020. This decline was primarily attributable to the introduction of a qualitative loss factor related to model imprecision. The ACL for residential and other consumer loans included $5.4$1.7 million related to the impact of Hurricanes Irma and Harvey. The ALLL includes $0.4 million related to loans that were downgraded during the three months ended September 30, 2017 as a result of 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 ALLL for non-coveredPCD loans at September 30, 2017 decreased slightly as compared to DecemberMarch 31, 2016. Decreases2020.
Increases in quantitative loss factors applied tothe ACL for the majority of theour commercial loan portfolio classes was primarily attributable to changes in the Company's reasonable and net decreases in qualitative factors were substantially offset by the impact of the growth of the loan portfolio andsupportable economic forecast. The increase also reflected an increase in specific reserves for criticizedof approximately $16 million summarized as follows:
An increase of $4.3 million in commercial and classifiedindustrial loans, including taxi medallion loans. Factors influencing the changeprimarily related to one previously identified $35 million Florida loan.
An increase of $15.2 million in the ALLLBridge franchise finance portfolio, 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.quick service restaurant concepts.
A decrease of $3.3$3.1 million for multi-family loans primarily reflects decreases in quantitative loss factors, the decline in the corresponding portfolio andBridge equipment finance portfolio.
Changes in the ACL from December 31, 2019 to January 1, 2020 represented the adoption of ASU 2016-13. In general, the change in methodology resulted in increased reserves due to the transition to a net decreaselifetime expected loss model from an incurred loss model. However, as noted 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 loansthe table above, there are certain CRE portfolios where the reserve decreased. This was primarilymainly driven by the growthuse of quantitative models to estimate the ACL at the loan level, specific to the Company's portfolio, under CECL, instead of the corresponding portfolio and an increase in criticized and classified loans, partially offset by a decrease in quantitativepeer group historical losses rates utilized under the prior incurred loss factors.
An increase of $3.7 million for owner occupied commercial real estate loansmodel. Certain qualitative factors were also removed, as their impact 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 growthcaptured 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 portfolio growth trends and credit concentrations.

As disclosed in the Company's Form 10-K for the year ended December 31, 2019, the Company had elected to phase-in the initial impact of adopting CECL for regulatory capital purposes, allowing CECL's regulatory capital effects to be phased in at 25 percent per year, beginning in the first year of adoption. As part of its response to the impact of COVID-19, our banking regulators issued an inter-agency interim final rule providing the option to temporarily delay the effects of CECL on regulatory capital for two years, followed by a three-year transition period. The Company has elected to adopt the provisions of this interim final rule.
Total stockholders' equity increaseddecreased by approximately $465 million at March 31, 2020 compared to $2.6 billion at September 30, 2017,December 31, 2019. The most significant reason for this decrease was a decline of $292 million in accumulated other comprehensive income for the three months ended March 31, 2020, attributed to an increase in unrealized losses on AFS securities and derivative instruments. See the section of $205 million, or 8.5%, from December 31, 2016, due primarilythis Management's Discussion and Analysis entitled "Analysis of Financial Condition; Investment Securities" and Note 3 to the retentionconsolidated financial statements for further discussion of earnings andunrealized losses on AFS securities. Management expects to recover the exerciseentire amortized cost basis of stock options resultingits AFS securities. Unrealized losses on derivative instruments designated as hedging instruments were attributable to reductions in proceeds of $61.5 million duringbenchmark interest rates. Other factors contributing to the period.
Since our formation, stockholders'decrease in total stockholders equity has been impacted primarily bywere the retention of earnings, and to a lesser extent, proceeds from the issuancerepurchase of common shares, the initial adoption of ASU 2016-13 which impacted retained earnings by $24 million, dividends in the amount of $22 million, and changes in unrealized gains and losses,the $31 million 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%loss for the threequarter.
We believe we are well positioned, from a capital perspective, to withstand a severe downturn in the economy. In light of the COVID-19 crisis, uncertainty around its ultimate impact on the economy and, nineby extension, on our financial condition and results of operations, we have enhanced our stress testing framework. We have increased both the frequency of stress testing and the spectrum of scenarios utilized. One exercise we completed was to stress our March 31, 2020 loan portfolio using both the 2018 DFAST severely adverse scenario and the 2020 DFAST severely adverse scenario. The results of each of these stress tests projected regulatory capital ratios in excess of all well capitalized thresholds.
During the three months ended September 30, 2017, respectively, compared to 55.7% and 58.4% March 31, 2020, the Company repurchased approximately 3.3 million shares of its common stock for the three and nine months ended September 30, 2016, respectively. We retainan aggregate purchase price of $101 million, at a high percentageweighted average price of our earnings to support our planned growth.$30.36 per share. The Company has temporarily suspended its share repurchase program.
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 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.
The onset of the COVID-19 pandemic led to dislocation and volatility in funding and capital markets and evoked widespread concerns about the ongoing functioning of those markets, the availability of liquidity and the economy generally. In response, the Federal Reserve reduced its benchmark interest rate to a target level of 0 - 0.25%, actively adjusted the size of its overnight and term repurchase agreement operations, reduced reserve requirements and the cost of discount window borrowings, encouraged banks to utilize the discount window and committed to purchasing large amounts of U.S. Treasury securities and MBS. The U.S. government has announced an unprecedented variety of additional stimulus and measures to support markets, the flow of credit, and systemic liquidity. These include the Primary Market Corporate Credit Facility, the Secondary Market Corporate Credit Facility, the Term Asset-Backed Securities Loan Facility, the Municipal Liquidity Facility, the Main Street New Loan Facility, the Main Street Expanded Loan Facility, Paycheck Protection Program loans, the Paycheck Protection Program Lending Facility (PPPLF), the Commercial Paper Funding Facility, the Primary Dealer Credit Facility, and the Money Market Mutual Fund Liquidity Facility. These actions appear to have been effective in stabilizing market liquidity.
In response to the onset of COVID-19 and potential concerns that might arise about the stability of liquidity, we took a number of precautionary measures to ensure adequacy of liquidity. We activated our liquidity contingency funding plan, which called for the implementation of a number of measures to increase the frequency and extent of monitoring and reporting of intraday liquidity, deposit flows and other liquidity trends as well as testing of all of our contingent liquidity sources. We took steps to optimize available same day liquidity. We increased the level of cash held on balance sheet, to be prepared to meet potential increased demand for deposit withdrawals and line usage, which to date have not materialized. We optimized same day available liquidity by pledging additional securities and loans to the FHLB and the discount window to support those sources of contingent liquidity.
At March 31, 2020, same day available liquidity totaled approximately $8.5 billion, including cash, borrowing capacity at the Federal Home Loan Bank of Atlanta and the Federal Reserve Discount Window and Federal Funds lines of credit, as depicted in the following chart:
liquidity.jpg
Additional sources of liquidity include cash flows from operations, wholesale deposits, and cash generated by the repayment and resolution of covered loans, cash payments receivedflow from the FDIC pursuant toBank's amortizing securities and loan portfolios. In 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. Thesenear-term, cash flows from the repayment or resolutionloan portfolio may be reduced as a result 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 relatedtemporary payment deferrals granted 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 expectedborrowers. We do not expect this 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’smaterially impact our 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.position. Management also has the ability to exert substantial control over the rate and timing of growth of the non-covered loan portfolio,production, and resultant requirements for liquidity to fund new loans.
Continued runoff We currently expect the majority of loan production, at least for the remainder of the covered loan portfoliosecond quarter, to be related to loans originated under the PPP and FDIC indemnification assetpotentially the Main Street Lending Facility. Since the onset of the COVID-19 pandemic, we have not experienced unusual deposit outflows or volatility. Credit line usage, which we have monitored daily since the onset of COVID-19, has deviated very little from our trailing three year average. PPP loans will be a near-term demand on liquidity; it is currently our intention to match fund these loans using the PPPLF, which we have successfully accessed. Our available liquidity may also be reduced as the FHLB and growth of deposits and the non-covered loan portfolio are the most significant trends expected to impact the Bank’s liquidityFederal Reserve Bank reprice our


collateral in the near term.normal course of business based on March 31, 2020 valuations. Based on our initial analysis, we do not expect the impact to be material to our overall liquidity position.
For the three months ended March 31, 2020 and 2019 net cash provided by operating activities was $63.5 million and $88.5 million, respectively. When compared with the three months ended March 31, 2019, operating cash flows were negatively impacted by approximately $65 million as a result of the daily settlement of derivative positions. These settlements, which are reported in cash flows from operating activities, are directly affected by changes in market interest rates.
The ALCO policy has established several measures of liquidity which are typically monitored monthly by the ALCO and quarterly by the Board of Directors. OneIn light of the COVID-19 situation, most of these measures, in addition to same day available liquidity and information about deposit flows, are currently being monitored and reported to executive management daily and to the Board of Directors weekly. The ALCO policy establishes limits for the ratio of available liquidity to volatile liabilities, the ratio of wholesale funding to total assets, the ratio of brokered deposits to total deposits and a government backed securities holding ratio, measured as the ratio of U.S. Government backed securities to total securities. At March 31, 2020 BankUnited was in compliance with all of these ALCO policy limits.
An additional primary measure of liquidity monitored by management is the 30 day30-day total liquidity ratio, defined as (a) the sum of cash and cash equivalents, pledgeable securities and a measure of funds expected to be generated by operations over the next 30 days; divided by (b) the sum of potential deposit runoff, liabilities maturing within the 30 day time frame and a measure of funds expected to be used in operations over the next 30 days. ALCO policy thresholds stipulate that BankUnited’s liquidity is considered acceptable if the 30 day30-day total liquidity ratio exceeds 100%. At September 30, 2017,March 31, 2020, BankUnited’s 30 day30-day total liquidity ratio was 172%141%. Management also monitors a one yearone-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,March 31, 2020, BankUnited’s one yearone-year liquidity ratio was 158%145%. Additional measures of liquidity regularly monitored by the ALCO include the ratio of wholesale fundingFHLB advances to total assets,funding, concentrations of large deposits, a measure of on balance sheet available liquidity to volatile liabilities and the ratio of brokerednon-interest bearing deposits to total deposits. At September 30, 2017, BankUnited was within acceptable limits established bydeposits, which is reflective of the ALCOquality and cost, rather than the quantity, of available liquidity. The Company also has a comprehensive contingency liquidity funding plan and conducts a quarterly liquidity stress test, the results of which are reported to the risk committee of the Board of Directors for each of these measures.Directors.
As a holding company, BankUnited, Inc. is a corporation separate and apart from its banking subsidiary, and therefore, provides for its own liquidity. BankUnited, Inc.’s main sources of funds include management fees and dividends from the Bank, access to capital markets and, to a lesser extent, its own available for sale securities portfolio. There are regulatory limitations that may affect the ability of the Bank to pay dividends to BankUnited, Inc. Management believes that such limitations will not impact our ability to meet our ongoing near-term cash obligations.
We expect that our liquidity requirements will continue to be satisfied over the next 12 months through the sources of funds described above.
Interest Rate Risk
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 activities is to maximize net interest income, while maintaining acceptable levels of interest rate risk. The ALCO is responsible for establishing policies to limit exposure to interest rate risk, and to ensure procedures are established to monitor compliance with these policies. The guidelinesthresholds 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


and economic climate. Currently, our model projects a down 100, plus 100, plus 200 and plus 300 basis point change with rates increasing by the magnitude of the rate ramp evenly over the next 12 months as well as flattening yield curve scenarios and instantaneous rate shocks of down 100, plus 100, plus 200, plus 300 and plus 300400 basis points.point shifts as well as a variety of yield curve slope 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 parallel 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. At March 31, 2020, the most likely rate scenario assumes that all indices are floored at 0%. The following table illustrates the acceptable limits as defined bythresholds set forth in the ALCO policy and the impact on forecasted net interest income of down 100, plus 100, plus 200 and plus 300 basis point rate shockin the indicated simulated scenarios at September 30, 2017March 31, 2020 and December 31, 2016:2019:

Management also simulates changes in EVE in various interest rate environments. The ALCO policy has established parameters of acceptable risk that are defined in terms of the percentage change in EVE from a base scenario under sixeight rate scenarios, derived by implementing immediate parallel movements of plus and minusdown 100, 200, 300 and 300400 basis points from current rates. We did not simulate decreases in interest rates greater than 100 basis points at September 30, 2017March 31, 2020 due to the currentcurrently low rate environment.level of market interest rates.

These measures fall within an acceptable level of interest rate risk per the policiesthresholds established byin 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.policy.
Many assumptions were used by the Company to calculate the impact of changes in interest rates, including the change in rates. Actual results may not be similar to the Company’s projections due to several factors including the timing and frequency of rate changes, market conditions, changes in depositor behavior and loan prepayment speeds and the shape of the yield curve. Actual results may also differ due to the Company’s actions, if any, in response to changing rates and conditions.
Derivative Financial Instruments
Interest rate swaps 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 suchand to changes in the fair value of fixed rate borrowings, 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, 2020, outstanding interest rate swaps designated as cash flow hedges had an aggregate notional amount of $2.0 billion. The aggregate fair value of$3.1 billion and outstanding interest rate swaps designated as cash flow

fair value hedges included in other assets was $1.1 million and thehad an aggregate notional amount of $250 million. The aggregate fair value of interest rate swaps designated as cash flow hedges included in other liabilities was $0.3$6.7 million.
Interest rate swaps and caps not designated as cash flow hedges had an aggregate notional amount of $2.3$3.0 billion at September 30, 2017.March 31, 2020. The aggregate fair value of these interest rate swaps and caps included in other assets was $27.3$135.7 million and the aggregate fair


value included in other liabilities was $26.8$42.3 million. These interest rate swaps and caps were entered into as accommodations to certain of our commercial borrowers. To mitigate interest rate risk associated with these derivatives, the Company enters into offsetting derivative positions with primary dealers.

Item 4. Controls and Procedures
Evaluation of Disclosure Controls and Procedures
As of the end of the period covered by this Form 10-Q, we carried out an evaluation under the supervision and with the participation of our management, including the Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures as defined in Exchange Act Rules 13a-15(e) and 15d-15(e). Based upon that evaluation, the Chief Executive Officer and the Chief Financial Officer concluded that our disclosure controls and procedures were effective.
Effective January 1, 2020, the Company adopted ASU 2016-13. The Company designed new controls and modified existing controls as part of its adoption.

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.
We received a subpoena from the United States Department of Justice in October 2019 requesting documentation related to the taxi medallion line of business formerly conducted by the Bank. We are cooperating with this investigation.
Item 1A.   Risk Factors
ForThe COVID-19 pandemic has caused substantial disruption to the global economy which has adversely affected, and is expected to continue to adversely affect, the Company’s business and results of operations. The future impacts of the COVID-19 pandemic on the global economy and the Company’s business, results of operations and financial condition remains uncertain.
In March 2020, the World Health Organization declared novel coronavirus disease 2019 (COVID-19) as a discussionglobal pandemic. The pandemic has resulted in governmental authorities implementing numerous measures attempting to contain the spread and impact of risk factors relatingCOVID-19 such as travel bans and restrictions, quarantines, shelter in place orders, and limitations on business activities, including in major markets in which the Company and its clients are located or do business. The COVID-19 pandemic, and governmental responses to the pandemic, have severely negatively impacted the global economy, disrupted global supply chains, lowered equity market valuations, created significant volatility and disruption in financial markets, and increased unemployment levels.
This macroeconomic environment has had, and could continue to have, an adverse effect on the Company’s business and operations. Should current economic impacts persist or continue to deteriorate, this macroeconomic environment could have a continued adverse effect on our business please referand operations, including, but not limited to, decreased demand for the Company’s products and services, protracted periods of lower interest rates, loss of income resulting from forbearances, deferrals and fee waivers provided by the Company to its consumer and commercial borrowers, increased credit losses due to deterioration in the financial condition of our consumer and commercial borrowers, including declining asset and collateral values, which may continue to increase our provision for credit losses and net charge-offs and possible constraints on liquidity and capital, whether due to increases in risk-weighted assets related to supporting client activities or to regulatory actions. The business operations of the Company may also be disrupted if significant portions of its workforce or those of vendors or third-party service providers are unable to work effectively, including because of illness, quarantines, government actions, restrictions in connection with the pandemic, and technology limitations and/or disruptions. The Company also faces an increased risk of litigation and governmental and regulatory scrutiny as a result of the effects of the pandemic on market and economic conditions and actions taken by governmental authorities in response to those conditions.


The extent to which the COVID-19 pandemic impacts the Company’s business, results of operations, and financial condition, as well as its regulatory capital and liquidity ratios, will depend on future developments, which are highly uncertain, including the scope and duration of the pandemic and actions taken by governmental authorities and other third parties in response to the factors discussed under “Part I-Item 1A - Riskpandemic. Moreover, the effects of the COVID-19 pandemic may heighten many of the other risks described in the section entitled “Risk Factors” in our 2016most recent Annual Report on Form 10-K and any subsequent Quarterly Report on Form 10-Q or Current Report on Form 8-K including, but not limited to, financial market conditions, economic conditions, credit risk, interest rate risk, risk of security breaches and technology changes.
There have been no material changes in the other risk factors disclosed by the Company in its 2019 Annual Report on Form 10-K filed with the Securities and Exchange Commission on February 28, 2017, in addition to the following factor.2020.
A significant portion
Item 2.   Unregistered Sales of our loans are to borrowers whose businesses are located in or secured by properties located in the stateEquity Securities and Use of Florida, which was impacted by Hurricane Irma. In addition, the Bank has 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 adverse impact on our results of operations.Proceeds
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 business or results of operations may be adversely impacted by these and other negative effects of such weather events.

We are currently in the process of assessing the impact of Hurricanes Irma and Harvey on our borrowers’ ability to repay their obligations to the Bank and on the value of underlying collateral properties. Although we currently believe the storms did not materially impact the ability of the substantial majority of our borrowers to repay their loans, our impact assessment is ongoing, 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.
(1)The total number of shares purchased during the periods indicated includes shares purchased as part of a publicly announced program.
(2)On September 12, 2019, the Company's Board of Directors authorized a share repurchase program under which the Company may repurchase up to $150 million of its outstanding common stock. No time limit was set for the completion of the share repurchase program. The authorization does not require the Company to acquire any specified number of common shares and may be commenced, suspended or discontinued without prior notice. Under this authorization, $44,997,312 remained available for purchase at March 31, 2020. On March 13, 2020, we announced the temporary suspension of the share repurchase program in light of the challenges presented by COVID-19 and surrounding events.
