The Loss Sharing Agreements consist of the Single Family Shared-Loss Agreementplatforms 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.regional wholesale banking offices.
The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X of the SEC.

Accounting Estimates
In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, and expenses and disclosures of contingent assets and liabilities. Actual results could differ significantly from these estimates.
Significant estimates includeThe most significant estimate impacting the ALLL,Company's consolidated financial statements is the amount and timing of expected cash flows from covered assets and the FDIC indemnification asset, and the fair values of investment securities and other financial instruments. Management has used information provided by third party valuation specialists to assist in the determination of the fair values of investment securities.ACL.

ASU No. 2017-08, Receivables—Nonrefundable Fees2023-09—Income Taxes (Topic 740): Improvements to Income Tax Disclosures. This ASU requires entities to provide additional disclosures, primarily related to the income tax rate reconciliation and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities.income taxes paid. The amendments inguidance also eliminates certain existing disclosure requirements related to uncertain tax positions among others. This ASU is effective for the Company for fiscal years beginning after December 15, 2024, and interim periods within fiscal years beginning after December 15, 2025. The adoption of 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 withhave no material impact on the Company's consolidated financial position, results of operations, orand cash flows.
ASU No. 2016-06, Derivatives Adoption will lead to additional 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 ASUrevised disclosures in the first quarter of 2017 with no impact on its consolidatedCompany's financial position, results of operations or cash flows.statements.
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, Financial Instruments - Credit Losses (Topic 326); Measurement of Credit Losses on Financial Instruments. The ASU introduces new guidance which makes substantive changes to the accounting for credit losses. The ASU introduces the CECL model which applies to financial assets subject to credit losses and measured at amortized cost, as well as certain off-balance sheet credit exposures. This includes loans, loan commitments, standby letters of credit, net investments in leases recognized by a lessor and held-to-maturity debt securities. The CECL model requires an entity to estimate credit losses expected over the life of an exposure, considering information about historical events, current conditions and reasonable and supportable forecasts. The ASU also modifies the current OTTI model for available for sale debt securities requiring an estimate of expected credit losses only when the fair value of an available for sale debt security is below its amortized cost. Credit losses on available for sale debt securities will be limited to the difference between the security's amortized cost basis and its fair value. The ASU also provides for a simplified accounting model for purchased financial assets with more than insignificant credit deterioration since their origination. The amendments in this ASU are effective for the Company for interim and annual periods in fiscal years beginning after December 15, 2019. Management has not yet completed its evaluation of the impact of adoption of this ASU and is not currently able to reasonably estimate the impact of adoption on the consolidated financial statements; however, adoption is likely to lead to significant changes in accounting policies related to, and the methods employed in estimating, the ALLL. It is possible that the impact will be material to the Company's consolidated financial position and results of operations.

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

The Company monitors its investment securities available for sale for OTTIcredit loss impairment on an individual security basis. No securities were determined to be other-than-temporarilycredit loss impaired during the ninethree months ended September 30, 2017. TheMarch 31, 2024 and 2023. At March 31, 2024, the Company doesdid not intendhave an intent to sell securities that arewere in significant unrealized loss positions, at September 30, 2017 and it iswas not more likely than not that the Company willwould be required to sell these securities before recovery of the amortized cost basis, which may be at maturity. In making this determination, the Company considered its current and projected liquidity position including its ability to pledge securities to generate liquidity, its investment policy as to permissible holdings and concentration limits, regulatory requirements and other relevant factors. We have not sold, and do not anticipate the need to sell, securities in unrealized loss positions to generate liquidity.
At September 30, 2017, 54March 31, 2024, 540 securities available for sale were in unrealized loss positions. The amount of impairment related to 20138 of these securities was considered insignificant both individually and in the aggregate, totaling approximately $237 thousand$1.3 million and no further analysis with respect to these securities was considered necessary.
The basis for concluding that impairment of the remainingAFS securities were not credit loss impaired and no ACL was not other-than-temporaryconsidered necessary at March 31, 2024, is further described below:discussed below.
Unrealized losses were primarily attributable to a sustained higher interest rate environment. In some cases, wider spreads compared to levels at which securities were purchased. market volatility and yield curve dislocations also contributed to unrealized losses. The investment securities AFS portfolio was in a net unrealized loss position of $498.4 million at March 31, 2024, compared to $534.8 million at December 31, 2023, improving by $36.4 million during the three months ended March 31, 2024. While the majority of securities in the portfolio were floating rate at March 31, 2024, fixed rate securities accounted for the majority of unrealized losses.

For five fixed rate securities, the impairment was primarily attributable to an increase in medium and long-term market interest rates subsequent to the date of acquisition. For the remaining seven variable rate securities, the amount of impairment was less than 1% of amortized cost. The timely payment of principal and interest on these securities is explicitly or implicitly guaranteed by the U.S. Government.

Private Label Securities:
None of the impaired private label securities had missed principal or interest payments or had been downgraded by a NRSRO at March 31, 2024. The Company performed an analysis comparing the present value of cash flows expected to be collected to the amortized cost basis of impaired securities. This analysis was based on a scenario that we believe to be generally more conservative than our reasonable and supportable economic forecast at March 31, 2024, and incorporated assumptions about voluntary prepayment rates, collateral defaults, delinquencies, severity and other relevant factors as described further below. Our analysis also considered the structural characteristics of each security and the level of credit enhancement provided by that structure.
Private label residential MBS and CMOs
At March 31, 2024, 115 private label residential MBS and CMOs were in unrealized loss positions. Our analysis of cash flows expected to be collected on these securities incorporated assumptions about collateral default rates, voluntary prepayment rates, loss severity, delinquencies and recovery lag. In developing those assumptions, we took into account collateral quality measures such as FICO, LTV, documentation, loan type, property type, agency availability criteria and performing status. We also regularly monitor sector data including home price appreciation, forbearance, delinquency, special servicing and prepay trends as well as other economic data that could be indicative of stress in the sector. Underlying delinquencies in this sector remain low. Our March 31, 2024 analysis projected weighted average collateral losses for impaired securities in this category of 2% compared to weighted average credit support of 18%. As of March 31, 2024, 95% of impaired securities in this category, based on carrying value, were externally rated AAA, 4% were rated AA and 1% were rated A.

Single family rental real estate-backed securities
At September 30, 2017, twoMarch 31, 2024, 11 single family rental real estate-backed securities were in unrealized loss positions. The unrealized losses were primarily due to increases in market interest rates since the purchase of the securities.

Given the limited severity of impairment and the absence of projected credit losses, the impairments were considered to be temporary.
State and municipal obligations
At September 30, 2017, 11 state and municipal obligations were in unrealized loss positions. The amount of impairment of each of the individual securities was less than 5% of amortized cost. All of the securities are rated investment grade by nationally recognized statistical ratings organizations. Management's evaluation of these securities for OTTI also encompassed the review of credit scores and analysis provided by a third party firm specializingstress in the sector.

Collateralized loan obligations
At March 31, 2024, 15 collateralized loan obligations were in unrealized loss positions. Unrealized losses totaled less than 1% of total amortized cost of this segment at March 31, 2024. Our analysis of cash flows expected to be collected on these securities incorporated assumptions about collateral default rates, loss severity, and delinquencies, calibrated to take into account idiosyncratic risks associated with the underlying collateral. In developing those assumptions, we took into account each sector’s performance pre-, during and post the 2008 financial crisis. We regularly engage with bond managers to monitor trends in underlying collateral including potential downgrades and subsequent cash flow diversions, liquidity, ratings migration, and any other relevant developments. While we have observed some deterioration in underlying collateral performance due in large part to rising costs, the high credit quality of these securities and adequacy of subordination to cover projected collateral losses supports the conclusion that there is no credit loss impairment. Our March 31, 2024 analysis projected weighted average collateral losses for impaired securities in this category of 11% compared to weighted average credit support of 42%. As of March 31, 2024, 80% of the impaired securities in this category, based on carrying value, were externally rated AAA, 12% were rated AA and 8% were rated A.
Non-mortgage asset-backed securities
At March 31, 2024, six non-mortgage asset-backed securities were in unrealized loss positions. These securities are backed by student loan collateral. Our analysis of cash flows expected to be collected on these securities incorporated assumptions about collateral default rates, loss severity, delinquencies, voluntary prepayment rates and recovery lag. In developing assumptions, we took into account collateral type, delineated by whether collateral consisted of loans to borrowers in school, refinancing, or a mixture. Our March 31, 2024 analysis projected weighted average collateral losses for impaired securities in this category of 4% compared to weighted average credit support of 26%.

The ACL was determined utilizing a 2-year reasonable and supportable forecast period. The quantitative portion of the ACL was determined using three weighted third-party provided economic scenarios.
The ACL increased by $14.9 million, from 0.82% to 0.90% of total loans, at March 31, 2024, compared to December 31, 2023. The more significant factors impacting the provision for credit losses and increase in the ACL for the three months ended March 31, 2024, were an increase in qualitative loss factors and risk rating migration, partially offset by an improved economic forecast.

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 orlesser extent global economy, 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 evaluatedrates, industry trends, demographic trends, inflationary trends, including particularly for impairment. Other commercial relationships on non-accrual status with committed balances under $1.0 million may also be evaluated individually for impairment, at management's discretion. The likelihood of loss related to loans assigned internal risk ratings of substandard or doubtful is considered elevated due to their identified credit weaknesses. Factors considered by management in evaluating impairment include payment status, financial condition of the borrower, collateral value, and other factors impacting the probability of collecting scheduled principal and interest payments when due.
ACI loans or pools are considered to be impaired when it is probable that the Company will be unable to collect all of the expected cash flows at acquisition (as adjusted for any additional cash flows expected to be collected arising from changes in estimates after acquisition), other than due to changes in interest rate indices and prepayment assumptions.

Non-covered loans contractually delinquent by 90 days or more and still accruing totaled $0.8 million and $1.6 million at September 30, 2017 and December 31, 2016, respectively. The amount of additional interest income that would have been recognized on non-accrual loans had they performed in accordance with their contractual terms was approximately $1.4 million and $3.7 million for the three and nine months ended September 30, 2017, respectively, and $1.1 million and $2.3 million for the three and nine months ended September 30, 2016, respectively.
Management considers delinquency status to be the most meaningful indicator of the credit quality of 1-4 single family residential, home equity and consumer loans. Delinquency statistics are updated at least monthly. See "Aging of loans" below for more information on the delinquency status of loans. Original LTV and original FICO score are also important indicators of credit quality for the non-covered 1-4 single family residential portfolio. 
valuations is a factor. Internal risk ratings are considered the most meaningful indicator of credit quality for commercial loans. Internal risk ratings are one indicator 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. LoansThe special mention rating is considered a transitional rating for loans exhibiting potential credit weaknesses that deserve management’s close attention and that if left uncorrected maycould result in deterioration of the repayment capacity of the borrower are categorized as special mention.prospects at some future date if not checked or corrected and that deserve management’s close attention. These borrowers may exhibit declining cash flows or revenues or increasing leverage. Loans with well-defined credit weaknesses includingthat may result in a loss if the deficiencies are not corrected are assigned a risk rating of substandard. These borrowers may exhibit payment defaults, declining collateral values, frequent overdrafts,inadequate cash flows from current operations, operating losses, increasing balance sheet leverage, inadequate cash flow, project cost overruns, unreasonable construction delays, exhausted interest reserves, declining collateral values, frequent overdrafts or past due real estate taxes or exhausted interest reserves, are assigned an internal risk rating of substandard.

Credit quality indicators for residential loans
Management considers delinquency status to be the most meaningful indicator of the credit quality of residential loans, other than government insured residential loans. Delinquency status is updated at least monthly. LTV and FICO scores are also important indicators of credit quality for 1-4 single family residential loans other than government insured loans. FICO scores are generally updated semi-annually, and were most recently updated in the Company'sfirst quarter of 2024. LTVs are typically at origination since we do not routinely update residential appraisals. Substantially all of the government insured residential loans atare government insured buyout loans, which the dates indicated. AmountsCompany 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 premiums, discountsnational and deferred feesregional economic conditions such as levels of unemployment, wages and costs (in thousands):

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. CoveredThe following tables summarize loans may be resolved through prepayment, short sale of the underlying collateral, foreclosure, sale of the loans or charge-off. For loans resolved through prepayment, short sale or foreclosure, the difference between consideration received in satisfaction of the loans and the carrying value of the loans is recognized in the consolidated statement of income line item “Income from resolution of covered assets, net.” Losses from the resolution of covered loans increase the amount recoverable from the FDIC under the Loss Sharing Agreements. Gains from the resolution of covered loans reduce the amount recoverable from the FDIC under the Loss Sharing Agreements. Similarly, differences in proceeds received on the sale of covered OREO and covered loans and their carrying amounts result in gains or losses and reduce or increase the amount recoverable from the FDIC under the Loss Sharing Agreements. Increases in valuation allowances or impairment charges related to covered assets also increase the amount estimated to be recoverable from the FDIC. These additions to or reductions in amounts recoverable from the FDIC related to transactions in the covered assets are recorded in the consolidated statement of income line item “Net gain (loss) on FDIC indemnification” and reflected as corresponding increases or decreases in the FDIC indemnification asset.
In addition, through June 30, 2017, recoveries of previously indemnified losses on assets that were formerly covered undermodified for borrowers experiencing financial difficulty, by type of modification, during the Commercial Shared-Loss Agreement resultedperiods indicated (dollars in reimbursements due to the FDIC.

The Company’s effective income tax rate was 32.2%28.6% and 31.7%26.4% for the three months ended September 30, 2017March 31, 2024 and 2016, respectively, and 31.2% and 33.2% for the nine months ended September 30, 2017 and 2016,2023, respectively. The effective income tax raterates differed from the statutory federal income tax rate of 35% in all periods21% for the three months ended March 31, 2024 and 2023 primarily due primarily to the effectimpact of state income taxes, partially offset by the benefit of income not subject to tax, offset by state income taxes.

Note 6    Derivative Financial Instruments
Derivatives designated as hedging instruments
The Company has investments in affordable housing limited partnerships which generate federal Low Income Housing Tax Credits and other tax benefits. The balance of these investments, included in other assets in the accompanying consolidated balance sheet, was $66 million and $71 million at September 30, 2017 and December 31, 2016, respectively. Unfunded commitments for affordable housing investments, included in other liabilities in the accompanying consolidated balance sheet, were $29 million and $53 million at September 30, 2017 and December 31, 2016, respectively. The maximum exposure to loss as a result of the Company's involvement with these limited partnerships at September 30, 2017 was approximately $73 million. While the Company believes the likelihood of potential losses from these investments is remote, the maximum exposure was determined by assuming a scenario where the projects completely fail and do not meet certain government compliance requirements resulting in recapture of the related tax credits. These investments did not have a material impact on income tax expense for the three and nine months ended September 30, 2017 and 2016.
Note 7    Derivatives and Hedging Activities
The Company usesentered into 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 arederivatives designated as (i) cash flow hedges with the objective of limiting the variability of interest payment cash flows resulting fromand (ii) fair value hedges designed to hedge changes in the fair value of outstanding fixed rate instruments caused by fluctuations in the benchmark interest rate LIBOR.rate. Changes in fair value of derivative instruments designated as cash flow hedges are reported in accumulated other comprehensive income.

Derivatives designated as fair value hedges
The amount of gain (loss) related to derivatives designated as fair value hedges recognized in earnings was insignificant for all applicable periods. The following table provides information about the hedged items related to derivatives designated as fair value hedges at the date indicated (in thousands):

(1)This amount is included in the amortized cost basis of a closed portfolio of loans used to designate hedging relationships in a portfolio layer method hedge in which the hedged item is anticipated to be outstanding for the designated hedge period. The amortized cost basis of the closed portfolio used in this hedging relationship was $976 million and $992 million, respectively, at March 31, 2024 and December 31, 2023.
Derivatives not designated as hedging instruments
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. The Company also purchases and sells credit protection under RPAs with the objective of sharing with financial institution counterparties some of the credit exposure related to interest rate derivative contracts entered into with commercial borrowers related to participations purchased or sold. The Company will make or receive payments under these agreements if a customer defaults on an obligation to perform under certain interest rate derivative contracts. 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. The impact on earnings related to changes in fair value of these derivatives was not material for the three and nine months ended September 30, 2017March 31, 2024 and 2016 was not material.2023.
The Company may be exposed to credit risk in the event of non-performance by the counterparties to its interest rate derivative agreements. The Company assesses the credit risk of its financial institution counterparties by monitoring publicly available credit rating and financial information. The Company manages dealer credit risk by entering into interest rate derivatives only with primary and highly rated counterparties, the use of ISDA master agreements, central clearing mechanisms and counterparty limits. The agreements contain bilateral collateral arrangements with the amount of collateral to be posted generally governed by the settlement value of outstanding swaps. The Company manages the risk of default by its commercial borrower counterparties through its normal loan underwriting and credit monitoring policies and procedures. The Company does not currently anticipate any significant losses from failure of interest rate derivative counterparties to honor their obligations.
The CME amended its rules effective January 2017 to legally characterize variation margin payments for centrally cleared derivatives as settlements of the derivatives' exposures rather than collateral. As a result, the variation margin payment and the related derivative instruments are considered a single unit of account for accounting and financial reporting purposes. The Company's clearing agent for interest rate derivative contracts centrally cleared through the CME settles the variation margin daily with the CME; therefore, those interest rate derivative contracts the Company clears through the CME are reported at a fair value of approximately zero at September 30, 2017.

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

The difference between the amounts reported for interest rate swaps subject to master netting agreements and the total fair value of interest rate contract derivative financial instruments reported in the consolidated balance sheets is related to interest rate derivative contracts entered into with borrowers not subject to master netting agreements.
At September 30, 2017, the Company had pledged investment securities available for sale with a carrying amount of $40 million and cash on deposit of $2 million as collateral for interest rate swaps in a liability position. $2 million of financial collateral was pledged by counterparties to the Company for interest rate swaps in an asset position. The amount of collateral required to be posted varies based on the settlement value of outstanding swaps and in some cases may include initial margin requirements.

Share Awards
Unvested share awards
During the nine months ended September 30, 2017, the Company granted 618,306 unvested share awards under the 2014 Plan. All of the shares vest in equal annual installments over a period of three years from the date of grant. The shares granted were valued at the closing price of the Company’s common stock on the date of grant, ranging from $33.21 to $40.84, and had an aggregate fair value of $24.9 million. The total unrecognized compensation cost of $26.7 million for all unvested share awards outstanding at September 30, 2017 will be recognized over a weighted average remaining period of 1.98 years.
During the nine months ended September 30, 2016, the Company granted 644,888 unvested share awards under the 2014 Plan. All of the shares vest in equal annual installments over a period of three years from the date of grant. The shares granted were valued at the closing price of the Company’s common stock on the date of grant, ranging from $29.78 to $33.76, and had an aggregate fair value of $20.0 million.
Executive share-based awards
Certain of the Company's executives are eligible to receive annual awards of RSUs and PSUs (collectively, the "share units"). Annual awards of RSUs represent a fixed number of shares and vest in equal tranches over three years. PSUs are initially granted based on a target value. The number of PSUs that ultimately vest at the end of a three-year performance measurement period will be based on the achievement of performance criteria pre-established by the Compensation Committee of the Board of Directors. The performance criteria established for the PSUs granted in 2017 and 2016 include both performance and market conditions. Upon vesting, the share units will be converted to common stock on a one-for-one basis, 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 this cash settlement, all RSUs and PSUs have been determined to be liability instruments and will be remeasured at fair value each reporting period until the awards are settled. The RSUs are valued based on the closing price of the Company's common stock at the reporting date. The PSUs are valued based on the closing price of the Company's common stock at the reporting date net of a discount related to any applicable market conditions, considering the probability of meeting the defined performance conditions. Compensation cost related to PSUs is recognized during the performance period based on the probable outcome of the respective performance conditions.
During the nine months ended September 30, 2017, 47,848 RSUs and 47,848 PSUs were granted. During the nine months ended September 30, 2016, 57,873 RSUs and 57,873 PSUs were granted. The total liability for the share units was $2.6 million at September 30, 2017. The total unrecognized compensation cost of $5.3 million for these share units at September 30, 2017 will be recognized over a weighted average remaining period of 2.18 years.

The 618,306 unvested share awards granted during the nine months ended September 30, 2017, as discussed above, included 25,321 unvested share awards granted to certain of the Company's executives based on the achievement of performance criteria pre-established by the Compensation Committee for the year ended December 31, 2016.
Incentiveawards
Beginning in 2017, the Company's annual incentive compensation arrangements provide for settlement through a combination of cash payments and unvested share awards following the end of the annual performance period. The dollar value of share awards to be granted is based on the achievement of performance criteria established in the incentive arrangements. The number of shares of common stock to be awarded is variable based on the closing price of the Company's stock on the date of grant; therefore, these awards are initially classified as liability instruments, with compensation cost recognized from the beginning of the performance period. The awards vest in equal installments over a period of three years from the date of grant. The total liability for the incentive share awards was $1.2 million at September 30, 2017. The total unrecognized compensation cost of $5.3 million for these share awards at September 30, 2017 will be recognized over a weighted average remaining period of 3.25 years. The accrued liability and unrecognized compensation cost are based on management's current estimate of the likely outcome of the performance criteria established in the incentive arrangements and may differ from actual results.

Note 108    Fair Value Measurements
Assets and liabilities measured at fair value on a recurring basis
FollowingThe following is a description of the methodologies used to estimate the fair values of assets and liabilities measured at fair value on a recurring basis and the level within the fair value hierarchy in which those measurements are typically classified.
Investment securities available for sale and marketable equity securities—Fair value measurements are based on quoted prices in active markets when available; these measurements are classified within level 1 of the fair value hierarchy. These securities typically include U.S. Treasury securities and certain preferred stocks. If quoted prices in active markets are not available, fair values are estimated using quoted prices of securities with similar characteristics, quoted prices of identical securities in less active markets, discounted cash flow techniques, or matrix pricing models. These securities are generally classified within level 2 of the fair value hierarchy and include U.S. Government agency securities, U.S. Government agency and sponsored enterprise MBS, preferred stock investments for which level 1 valuations are not available, corporate debt securities, non-mortgage asset-backed securities, single family rental real estate-backed securities, certain private label residential MBS and CMOs, private label commercial MBS, collateralized loan obligations and state and municipal obligations. Pricing of these securities is generally primarily spread driven. Observable inputs that may impact the valuation of these securities include benchmark yield curves, credit spreads, reported trades, dealer quotes, bids, issuer spreads, current rating, historical constant prepayment rates, historical voluntary prepayment rates, structural and waterfall features of individual securities, published collateral data, and for certain securities, historical constant default rates and default severities. Investment securities available for sale generally classified within level 3 of the fair value hierarchy include certain private label MBS and trust preferred securities. The Company typically values these securities using third-party proprietary pricing models, primarily discounted cash flow valuation techniques, which incorporate both observable and unobservable inputs. Unobservable inputs that may impact the valuation of

36

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 monthlyquarterly basis. Any price evidencing unexpected monthquarter over monthquarter 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 nature of the valuation inputs and the limited availability of market pricing, servicing rights are classified as level 3.
Derivative financial instruments—Fair values of interest rate swapsderivatives are determined using widely accepted discounted cash flow modeling techniques. These discounted cash flow models use projections of future cash payments and receipts that are discounted at mid-market rates. Observable inputs that may impact the valuation of these instruments include LIBORbenchmark swap rates and LIBORbenchmark forward yield curves. These fair value measurements are generally classified within level 2 of the fair value hierarchy.

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

Investment grade $34,245
 Discounted cash flow Voluntary prepayment rate 6.60% - 25.60% (15.92%)
      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%)
         
Non-investment grade $26,552
 Discounted cash flow Voluntary prepayment rate 1.10% - 29.30% (15.35%)
      Probability of default 0.13% - 4.15% (1.51%)
      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

40

BANKUNITED, INC. AND SUBSIDIARIES

September 30, 2017


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. classified:
ImpairedCollateral dependent loans OREOand other repossessed assetsOREO—The carrying amount of collateral dependent impaired loans is typically based on the fair value of the underlying collateral, which may be real estate, taxi medallions,enterprise value or other business assets, less estimated costs to sell.sell when repayment is expected to come from the sale of the collateral. The carrying value of OREO is initially measured based on the fair value of the real estate acquired in foreclosure and subsequently adjusted to the lower of cost or estimated fair value, less estimated cost to sell. Fair values of real estate collateral and OREO are typically based on third-party real estate appraisals which utilize market and income approaches to valuation incorporating both observable and unobservable inputs. When current appraisals are not available, the Company may use brokers’ price opinions, home price indices or other available information about changes in real estate market conditions to adjust the latest appraised value available. These adjustments to appraised values may be subjective and involve significant management judgment. The fair value of repossessed assets, other than taxi medallions, or collateral consisting of other business assets may be based on third-party appraisals or internal analyses that use market approaches to valuation incorporating primarily unobservable inputs.
The fair value of New York City taxi medallions is based primarily on an internal analysis that utilizes an income approach to valuation. This analysis utilizes data obtained from the NYTLC about the fleet in general and in some cases, our portfolio specifically, and management's assumptions, based on external data when available, about revenues, costs and expenses, to estimate the value that can reasonably be supported by the cash flow generating capacity of a medallion. We further discount the results of this analysis in recognition of estimated selling costs and declining trends in medallion values. We also consider prices of recent medallion transfers as published by the NYTLC; however, the market for taxi medallions is illiquid and information about the circumstances underlying observed transfers is unavailable, therefore, information about recent transfers is not considered sufficient to establish a reliable estimate of value. The Company's medallion valuations fall within the range of published transfer prices over the last six months. Taxi medallions in municipalities other than New York City are generally valued based on published information about recent transfer prices; the valuation of these assets did not have a material impact on the Company's consolidated financial statements for any period presented as the taxi medallion portfolio is heavily concentrated in New York City.

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

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.

Some of these commitments may mature without being fully funded.funded, so may not necessarily represent future liquidity requirements. 
Commercial and standby letters of credit
Letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. These letters of credit are primarily issued to support trade transactions or guarantee arrangements. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers.

Overview
Quarterly HighlightsNet income for the three months ended March 31, 2024, was $48.0 million, or $0.64 per diluted share, compared to $52.9 million, or $0.70 per diluted share for the three months ended March 31, 2023. For the three months ended March 31, 2024, the annualized return on average stockholders' equity was 7.31% and the annualized return on average assets was 0.54%.
In evaluating our financial performance, we consider the level of and trends in net interest income, the net interest margin, levels and compositionthe cost of deposits, trends in 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 inthe composition of earning assets and deposits, trends inthe funding mix, the composition and costlevel of funds.available liquidity and our interest rate risk profile. We analyze these ratios and trends against our own historical performance, our budgetedexpected performance, our risk appetite and the financial condition and performance of comparable financial institutions.
Quarterly highlights include:In response to evolving macro-environmental factors, we have established the following near-term strategic priorities for our Company:
Net income forImprove the quarter ended September 30, 2017 was $67.8 million, or $0.62 per diluted share, compared to $50.8 million, or $0.47 per diluted share, forBank's funding profile by growing core deposits and paying down higher cost wholesale funding;
Improve the quarter ended September 30, 2016. Forasset mix by re-positioning the nine months ended September 30, 2017, net income was $196.5 million, or $1.79 per diluted share, compared to $162.4 million, or $1.50 per diluted share, for the nine months ended September 30, 2016. Earnings for the nine months ended September 30, 2017 generated an annualized return on average stockholders' equity of 10.21%balance sheet away from typically lower yielding transactional business such as residential mortgages and an annualized return on average assets of 0.92%.
organically growing core commercial loans;
Net interest income increased by $19.5 million to $241.3 million for the quarter ended September 30, 2017 from $221.7 million for the quarter ended September 30, 2016. Interest income increased by $39.5 million, driven by increases in the average balances of loans and investment securities outstanding and an increase in the yield on interest earning assets. Interest expense increased by $19.9 million, driven by increases in average interest bearing liabilities and the cost of those liabilities. For the nine months ended September 30, 2017, net interest income increased by $68.6 million to $711.4 million from $642.9 million for the nine months ended September 30, 2016.
The net interest margin, calculated on a tax-equivalent basis, decreased to 3.62% for the quarter ended September 30, 2017 from 3.69% for the quarter ended September 30, 2016 and 3.76% for the immediately preceding quarter ended June 30, 2017. Significant factors contributing to the decline inImprove the net interest margin, includedlargely a function of more profitable balance sheet composition;
Maintain robust liquidity and capital;
Continue to manage credit;
Manage the rate of growth in operating expenses.
The three months ended March 31, 2024 embodied strong execution on these key strategic priorities:
The funding mix continued run-offto improve as non-interest bearing demand deposits grew by $404 million for the three months ended March 31, 2024. Non-brokered deposits grew by $644 million and total deposits grew by $489 million.

The C&I and an increase incommercial real estate portfolios declined by $226 million. This decline was related to expected seasonality as well as some notable unexpected paydowns and the cost of interest bearing liabilities. decision to exit some non-relationship shared national credits.
The net interest margin, calculated on a tax-equivalent basis was 3.69%relatively stable at 2.57% compared to 2.60% for the ninethree months ended September 30, 2017December 31, 2023. The net interest margin was 2.62% for the three months ended March 31, 2023.

The NPA ratio at March 31, 2024 declined to 0.34%, including 0.11% related to the guaranteed portion of non-performing SBA loans, from 0.37%, including 0.12% related to the guaranteed portion of non-performing SBA loans at December 31, 2023.
Liquidity is ample. Total same day available liquidity was $14.8 billion, the available liquidity to uninsured, uncollateralized deposits ratio was 156% and an estimated 65% of our deposits were insured or collateralized at March 31, 2024.
Our capital position is robust. At March 31, 2024, CET1 was 11.6% and pro-forma CET1, including accumulated other comprehensive income, was 10.3%. The ratio of tangible common equity/tangible assets increased to 7.3%.
Quarterly Highlights:
The average cost of total deposits increased to 3.18% for the three months ended March 31, 2024, from 2.96% for the immediately preceding three months ended December 31, 2023, and 2.05% for the three months ended March 31, 2023. The cost of deposits is showing signs of stabilizing. On a spot basis, the cost of total deposits was 3.17% at March 31, 2024 compared to 3.75%3.18% at December 31, 2023.
Commercial real estate exposure is modest. Commercial real estate loans totaled 24% of loans at March 31, 2024, representing 166% of the Bank's total risk-based capital. By comparison, based on call report data as of December 31, 2023, (the most recent date available) for banks with between $10 billion and $100 billion in assets, the median level of CRE to total loans was 35% and the median level of CRE to total risk based capital was 225%.
At March 31, 2024, the ratio of the ACL to total loans was 0.90% compared to 0.82% at December 31, 2023. The ACL to loans ratio for commercial portfolio sub-segments including C&I, CRE, franchise finance and equipment finance was 1.42% at March 31, 2024 and the ACL to loans ratio for CRE office loans was 2.26%.
Non-interest expense for the ninethree months ended September 30, 2016.March 31, 2024 included an additional $5.2 million related to the FDIC special assessment announced in the fourth quarter of 2023.
Total interest earning assets increasedThe net unrealized pre-tax loss on the AFS securities portfolio continued to improve, declining 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

September 30, 2017, total interest earning assets increased by $1.9 billion and non-covered loans and leases grew by $1.3 billion.
Total deposits increased by $445$36 million for the quarter ended September 30, 2017 to $21.2 billion. For the ninethree months ended September 30, 2017, total deposits increased by $1.7 billion.March 31, 2024, now representing 5% of amortized cost. The duration of our AFS securities portfolio remained short at 1.85 at March 31, 2024. HTM securities were not significant.
At September 30, 2017, 96.7% of the non-covered commercial loan portfolio was rated "pass"Book value 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.

The provision for loan losses for the quarter and nine months ended September 30, 2017 totaled $37.9 million and $63.6 million, respectively, compared to $24.4 million and $42.4 million, respectively, for the comparable periods of the prior year. The most significant reason for these increases in the provision for loan losses was the provision related to the taxi medallion portfolio as discussed further in the sections entitled "Asset Quality" and "Analysis of the Allowance for Loan and Lease Losses."

Gain on sale of investment securities available for sale, net totaled $26.9 million for the quarter ended September 30, 2017. Substantially all of these gains related to sales of securities formerly covered under the Commercial Shared-Loss Agreement.

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.
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 and monetary policy, 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 liabilitiesfunding sources is influenced by the Company's liquidity profile, management's assessment of the desire for lower cost funding sources weighed against relationships with customers, our ability to attract and growth requirements and is impacted byretain core deposit relationships, competition for deposits in the Company's markets and the availability and pricing of other sources of funds.
Net interest income is also impacted by the accounting for ACI loans acquired in conjunction with the FSB Acquisition. ACI loans were initially recorded at fair value, measured based on the present value of expected cash flows. The excess of expected cash flows over carrying value, known as accretable yield, is recognized as interest income over the lives of the underlying loans. The positive impact of accretion related to ACI loans on the net interest margin and the interest rate spread is expected to continue to decline as ACI loans comprise a declining percentage of total loans. The proportion of total loans represented by ACI loans is declining as the ACI loans are resolved and new loans are added to the portfolio. ACI loans represented 2.5% and 3.0% of total loans, including premiums, discounts and deferred fees and costs, at September 30, 2017 and December 31, 2016, respectively. As this trend continues, assuming an otherwise stable interest rate environment, we would expect our net interest margin and interest rate spread to decrease as covered loans are resolved.
The impact of ACI loan accounting on net interest income makes it difficult to compare our net interest margin and interest rate spread to those reported by other financial institutions.

The following table presents, for the periods indicated, information about (i) average balances, the total dollar amount of taxable equivalent interest income from earning assets and the resultant average yields; (ii) average balances, the total dollar amount of interest expense on interest bearing liabilities and the resultant average rates; (iii) net interest income; (iv) the interest rate spread; and (v) the net interest margin. Non-accrual and restructured loans are included in the average balances presented in this table; however, interest income foregone on non-accrual loans is not included. Interest income, yields, spread and margin have been calculated on a tax-equivalent basis for loans and investment securities that are exempt from federal income taxes, at a federal tax rate of 35.0%21% (dollars in thousands):

Three months ended September 30, 2017March 31, 2024 compared to the three months ended September 30, 2016December 31, 2023
Net interest income, calculated on a tax-equivalent basis, was $218.9 million for the three months ended March 31, 2024, compared to $221.4 million for the three months ended December 31, 2023, a decrease of $2.5 million. The decrease in net interest income was comprised of decreases in tax-equivalent interest income of $1.9 million and increases in interest expense totaling $0.6 million, for the three months ended March 31, 2024, compared to the three months ended December 31, 2023. The net interest margin, calculated on a tax-equivalent basis, was 2.57% for the three months ended March 31, 2024, compared to 2.60% for the three months ended December 31, 2023.
Factors impacting the net interest margin for the three months ended March 31, 2024, compared to the three months ended December 31, 2023, included:
The tax-equivalent yield on loans increased to 5.78% for the three months ended March 31, 2024, from 5.69% for the three months ended December 31, 2023. This increase reflects the originations of new loans at higher rates, paydowns of lower rate loans and balance sheet repositioning.
The tax-equivalent yield on investment securities decreased to 5.59% for the three months ended March 31, 2024, from 5.73% for the three months ended December 31, 2023. The primary driver of this decrease was routine accounting adjustments recorded in the three months ended December 31, 2023 related to prepayment speeds on certain securities; these adjustments positively impacted the yield for the three months ended December 31, 2023.
The average rate paid on interest bearing deposits increased to 4.21% for the three months ended March 31, 2024, from 4.04% for the three months ended December 31, 2023. An increase in municipal money market deposits late in the fourth quarter of 2023 and CD repricing were contributing factors.
The average rate paid on FHLB advances decreased to 4.18% for the three months ended March 31, 2024 from 4.58% for the three months ended December 31, 2023, primarily due to repayment of higher rate advances.
Three months ended March 31, 2024 compared to the three months ended March 31, 2023
Net interest income, calculated on a tax-equivalent basis, was $252.0$218.9 million for the three months ended September 30, 2017March 31, 2024, compared to $230.5$232.1 million for the three months ended September 30, 2016, an increaseMarch 31, 2023, a decrease of $21.5 million. The increase in net interest income was$13.2 million, comprised of an increaseincreases in tax-equivalent interest income and interest expense of $41.5$40.9 million offset by anand $54.1 million, respectively. The increase in interest expense of $19.9 million.
The increase in tax-equivalent interest income was comprised primarily of a $27.9 million increase in interest income from loans and a $12.8 million increase in interest income 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% forMarch 31, 2024 compared to 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 $74.5 million for the three months ended September 30, 2017 and 2016, respectively. The tax-equivalent yield on those loans increased to 56.70% for the three months ended September 30, 2017 from 42.50% for the three months ended September 30, 2016. The increase in the yield on covered loans resulted primarily from improvements in expected cash flows for ACI loans.
The impact on the overall yield on loans of increasedMarch 31, 2023, reflected rising yields on both covered and non-covered loans considered individually was somewhatinterest earning assets that more than offset by the continued increasedecline 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 ofinterest earning assets. Similarly, the increase in interest expense for the three months ended September 30, 2017 asMarch 31, 2024 compared to the three months ended September 30, 2016 were a $15.0 millionMarch 31, 2023, resulted from an increase in the cost of interest expense on deposits and a $5.0 million increase in interest expense on FHLB advances.
The increase in interest expense on deposits was attributable to an increase of $2.5 billionbearing liabilities that more than offset the decline 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% for 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.
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.liabilities.
The net interest margin, calculated on a tax-equivalent basis, was 2.57% for the three months ended September 30, 2017 was 3.62% asMarch 31, 2024, compared to 3.69%2.62% for the three months ended September 30, 2016.March 31, 2023. The increase in cost of deposits outpaced the increase in the yield on interest rate spread decreased to 3.43%earning assets for the comparative periods. Increased yields on average interest earning assets as well as the increase in the cost of deposits reflected increasing market interest rates.
Further discussion of factors impacting the net interest margin for the three months ended September 30, 2017 March 31, 2024 compared to the three months ended March 31, 2023 follows:
The tax-equivalent yield on loans expanded to5.78% for the three months ended March 31, 2024, from 3.53%5.10% for the three months ended March 31, 2023. Factors contributing to this increase were the resetting of variable rate loans at higher coupon rates, runoff of lower rate loans including residential mortgages and originations of new loans at higher prevailing rates and wider spreads. Average residential loans, which are generally lower-yielding, declined by $709 million while average commercial loans increased by $322 million for the quarter ended March 31, 2024 compared to the quarter ended March 31, 2023.
The tax-equivalent yield on investment securities increased to 5.59% for the three months ended March 31, 2024, from 4.95% for the three months ended March 31, 2023. This increase resulted primarily from the reset of coupon rates on variable rate securities and to a lesser extent, purchases of higher-yielding securities and paydowns and sales of lower-yielding securities.

The average cost of total deposits increased to 3.18% for the three months ended September 30, 2016. March 31, 2024, from 2.05% for the three months ended March 31, 2023. This increase resulted from increases in market interest rates and a shift from non-interest bearing deposits to interest bearing deposits.
The declines in net interest margin and interestaverage rate spread resultedpaid on FHLB advances decreased to 4.18% for the three months ended March 31, 2024, from 4.27% for the three months ended March 31, 2023, primarily fromdue to repayment of higher rate advances.
Provision for Credit Losses
The provision for credit losses is a charge or credit to earnings required to maintain the ACL at a level consistent with management’s estimate of expected credit losses on financial assets carried at amortized cost at the balance sheet date. The amount of 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 beprovision is impacted by changes in market interest rates, includingcurrent economic conditions as well as in management's reasonable and supportable economic forecast, loan originations and runoff, changes in portfolio mix, risk rating migration and portfolio seasoning, changes in specific reserves, changes in expected prepayment speeds and other assumptions. The provision for credit losses also includes amounts related to off-balance sheet credit exposures and may include amounts related to accrued interest receivable and AFS debt securities.

Ninethree months ended September 30, 2017 compared to nine months ended September 30, 2016
Net interest income, calculated on a tax-equivalent basis, 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 ofMarch 31, 2024, were an increase in tax-equivalent interest income of $117.6 million,qualitative loss factors, particularly related to the office CRE portfolio sub-segment, and risk rating migration, 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 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. The tax-equivalent yield on those loans increased to 53.54% for the nine months ended September 30, 2017 from 40.48% for the nine months ended September 30, 2016.
The average balance of investment securities increased by $1.0 billion for the nine months ended September 30, 2017 from the nine months ended September 30, 2016 while the tax-equivalent yield increased to 3.07% from 2.82%.
The components of the increase in interest expense for the nine months ended September 30, 2017 as compared to the nine months ended September 30, 2016 were a $33.7 million increase in interest expense on deposits and an $8.3 million increase in interest expense on FHLB advances.
The increase in interest expense on deposits was attributable to an increase of $2.4 billion in average interest bearing deposits and an increase in the average cost of interest bearing deposits of 0.16% to 0.94% for the nine months ended September 30, 2017 from 0.78% for the nine months ended September 30, 2016. The increase in interest expense on FHLB advances was primarily a result of an increase in the average cost of advances of 0.19% to 1.21% for the nine months ended September 30, 2017 from 1.02% for the nine months ended September 30, 2016.
Factors contributing to the changes in yields and costs for the nine month periods were generally consistent with those for the three month periods discussed above.
The net interest margin, calculated 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.
Provision for Loan Lossesimproved economic forecast.
The provision for loancredit losses ismay be volatile and the amountlevel of expense that, based on our judgment, is requiredthe ACL may change materially from current levels. Future levels of the ACL could be significantly impacted, in either direction, by changes in factors such as, but not limited to, maintaineconomic conditions or the ALLL at an adequate level to absorb probable losses inherent ineconomic outlook, the composition of the loan portfolio, at the balance sheet datefinancial condition of our borrowers and that, in management’s judgment, is appropriate under GAAP. collateral values.
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.
TheACL and about factors that impacted the ACL and 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.

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

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 statements for further details about the components of these gains and losses associated with covered assets, along with the related additions to or reductions in the amounts recoverable from the FDIC under the Loss Sharing Agreements, as reflected in the consolidated statements 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.
The following table provides further detail of the components of income from resolution of covered assets, net, for the periods indicated (in thousands):

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

The Bank did not sell covered residential loans inmarketable equity securities during the three months ended September 30, 2017, dueMarch 31, 2023, were attributable to losses related to certain preferred equity investments.
The decrease in lease financing revenue for the three months ended March 31, 2024, compared to the potentialthree months ended March 31, 2023, was attributable to the impact of Hurricane Irma on the market for these loans, the collateral for many of which is located in Florida.
Pricing received on the sale of covered loans may vary based on (i) market conditions, includingsome operating lease equipment, reducing the interest rate environment,size of the amount of capital seeking investment and the secondary supply of loans with a particular performance history or collateral type, (ii) the type and quality of collateral, (iii) the performance history of loans included in the sale and (iv) whether or not the loans have been modified. We anticipate that we will continue to exercise our right to sell covered residential loans on a quarterly basis in the future.portfolio.
Other components of non-interest income
37


Period over period increases in income from lease financing corresponded to the growth in the portfolio of equipment under operating lease.
Gains on sale of non-covered loans for the three and nine months ended September 30, 2017 and 2016 related primarily to sales of loans by SBF.


Gain on sale of investment securities available for sale, net totaled $26.9 million for the quarter ended September 30, 2017. Substantially all of these gains resulted from the sale of securities formerly covered under the Commercial Shared-Loss Agreement and originally acquired at significant discounts in the FSB Acquisition. Other gains on investment securities available for sale for the three and nine months ended September 30, 2017 and 2016 related to sales of securities in the normal course of managing liquidity, portfolio duration and yield.

The increases in deposit insurance expense was primarily attributable to an additional $5.2 million related to an FDIC special assessment during the three months ended March 31, 2024.
Annualized non-interest expense as a percentageThe decline in depreciation of average assets was 2.1% and 2.2%operating lease equipment for the three and nine months ended September 30, 2017, respectively, and 2.2% and 2.3% for the three and nine months ended September 30, 2016, respectively. 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.
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 for the three and nine months ended September 30, 2017 increased by $3.2 million and $12.0 millionMarch 31, 2024, compared to the corresponding periods in 2016. The increases for the three and nine months ended September 30, 2017March 31, 2023, is 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 amortizedattributed to the amount ofreduction in operating lease equipment, corresponding to 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 periodsdecline in 2016.lease financing revenue.
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.Income Taxes
See Note 5 to the consolidated financial statements for a rollforward of the FDIC indemnification asset for the nine months ended September 30, 2017 and the year ended December 31, 2016. The entire balance of the FDIC indemnification asset relatesinformation about income taxes.

to residential loans and OREO covered under the Single Family Shared-Loss Agreement. The following table presents the carrying value of the FDIC indemnification asset and the estimated future cash flows at the dates indicated (in thousands):
 September 30, 2017 December 31, 2016
FDIC indemnification asset$349,617
 $515,933
Less expected amortization(173,685) (245,350)
Amount expected to be collected from the FDIC$175,932
 $270,583
The amount of expected amortization reflects the impact of improvements in cash flows expected to be collected from the covered loans, as well as the impact of time value resulting from the discounting of the asset when it was initially established. This amount will be amortized to non-interest expense using the effective interest method over the period during which cash flows from the FDIC are expected to be collected, which is limited to the lesser of the contractual term of the Single Family Shared-Loss Agreement and the expected remaining life of the indemnified assets.
Deposit insurance expense
Deposit insurance expense increased $0.8 million and $4.0 million, respectively, for the three and nine months ended September 30, 2017 compared to the corresponding periods in 2016. These increases primarily reflect the growth of the balance sheet, the large bank surcharge imposed by the FDIC, which began in the third quarter of 2016, and increases in certain components of the Bank's assessment rate.
Depreciation of equipment under operating lease
Depreciation of equipment under operating lease increased by $2.1 million and $5.7 million, respectively, for the three and nine months ended September 30, 2017 compared to the corresponding periods in 2016. These increases generally correspond to the growth in the portfolio of equipment under operating lease.
Other non-interest expense
The most significant components of other non-interest expense are advertising and promotion, costs related to lending activities and deposit generation, OREO related expenses, insurance, travel and general office expense. Other non-interest expense for the three months ended September 30, 2017 includes $0.6 million related primarily to facilities damage and employee relocation and assistance due to the impact of Hurricane Irma. We do not expect future expenses related to facilities damage and employee relocation to be material to the Company.
Income Taxes
The Company’s effective income tax rate was 32.2% and 31.2% for the three and nine months ended September 30, 2017, respectively, compared to 31.7% and 33.2% for the three and nine months ended September 30, 2016, respectively. Significant components included in the reconciliation of the Company's effective income tax rate to the statutory federal tax rate of 35.0% included the effect of state income taxes and the impact of income not subject to federal tax for each of the periods presented. In addition, the effective income tax rate for the three and nine months ended September 30, 2017 reflected the impact of $0.3 million and $3.2 million, respectively, in excess tax benefits resulting from activity related to vesting of share-based awards and exercise of stock options.
Analysis of Financial Condition
Average interest-earning assets increased $3.2 billionOur funding profile has continued to $26.9 billion forimprove. Total deposits grew by $489 million during the ninethree months ended September 30, 2017 from $23.7 billion forMarch 31, 2024, to $27.0 billion; non-brokered deposits grew by $644 million. Most of the nineincrease in total deposits was in non-interest bearing demand deposits, which grew by $404 million, to 27% of total deposits. During the three months ended September 30, 2016. This increase was drivenMarch 31, 2024, FHLB advances declined by a $2.1$1.2 billion, increase inas we paid down higher rate advances.
Total loans declined by $407 million during the average balance of outstanding loans and a $1.0 billion increase inthree months ended March 31, 2024. As we continue to reposition the average balance of investment securities. The increase in average loans reflected growth of $2.3 billion in average non-covered loans outstanding, partially offset by a $186 million decrease in the average balance of covered loans. The decrease in average non-interest earning assets period over period primarily reflected a decrease in the FDIC indemnification asset. Growth in interest earning assets, resolution of covered loans and declines in the amountleft side of the FDIC indemnification asset are trends that are expectedbalance sheet, residential loans declined by $152 million; franchise, equipment, and municipal finance declined by an aggregate $53 million. The C&I and CRE portfolios declined by $226 million; while production was in line with expectations, seasonality, some unexpected paydowns and exits of some shared national credits contributed to continue.this decline.
Average interest bearing liabilities increased $2.6 billion to $22.4 billion for the nine months ended September 30, 2017 from $19.8 billion for the nine months ended September 30, 2016, due to increases of $2.4 billion in average interest bearing deposits and $191 million in average FHLB advances. Average non-interest bearing deposits increased by $90 million. We expect growth in average deposits to continue, corresponding to anticipated growth in interest earning assets.
38




Average stockholders' equity increased by $255 million, due primarily to the retention of earnings, but also reflecting proceeds from the exercise of stock options and an increase in accumulated other comprehensive income.

Our investment strategy hasis focused on insuringensuring adequate liquidity, addingmaintaining a suitable balance of high credit quality, diversifyingdiverse assets, to the consolidated balance sheet, managing interest rate risk, and generating acceptable returns given our established risk parameters. We have sought to maintain liquidity by investing a significant portion of the portfolio in high quality liquid securities including U.S. Treasury securities, SBA securities and U.S. Government agency MBS.Agency and sponsored enterprise securities. We have also invested in highly-rated structured products, including private-label commercial and residential MBS, collateralized loan obligations, single family real estate-backed securities and non-mortgage asset-backed securities that, while somewhat less liquid, are generally pledgeable at either the FHLB or the FRB and provide us with attractive yields. Investment grade municipal securities provide liquidity along with higherand attractive tax-equivalent yields at longer durations thanyields. We remain committed to keeping the duration of our securities portfolio in general. We have also invested in highly rated structured products that, while somewhat less liquid, provide us with attractive yields.

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

Our evaluation of non-agency impaired securities for OTTI as of September 30, 2017 included consideration of the potential impacts of Hurricanes Irma and Harvey. Our considerations included but were not necessarily limited to (i) observations of market pricing since the hurricanes, (ii) whether a significant portion of the underlying collateral wasat the individual security level.
We regularly engage with bond managers to monitor trends in an

impacted area, (iii) whether credit enhancement significantly exceeded the balance ofunderlying collateral, in impacted areas, (iv) for residential mortgage-backed securities, the evaluation of the extentincluding potential downgrades and nature of damage to residential collateral for loans in the Bank’s residential loan portfolio located in the same areas,subsequent cash flow diversions, liquidity, ratings migration, and (v) discussions with sponsors or managers of individual securities about specific collateral impact.
During the three and nine months ended September 30, 2016, OTTI was recognized on two positions in one private label commercial MBS. These positions were in unrealized loss positions at September 30, 2016 and the Company intended to sell the security before recovery of the amortized cost basis. No securities were determined to be other-than-temporarily impaired at September 30, 2017, or during the three and nine months then ended.any other relevant developments.
We do not intend to sell securities in significant unrealized loss positions at September 30, 2017.March 31, 2024. 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.basis, which may be at maturity.

While for some securities, we have seen an increase in stress scenario losses over the full faith and credit oflast year, the U.S. Government. Management performed projected cash flow analyses of the private label residential MBS and CMOs, private label commercial MBS and non-mortgage asset-backed securities in unrealized loss positions, incorporating CUSIP level assumptions consistent with the collateral characteristics of each security including collateral default rate, voluntary prepayment rate, severity and delinquency assumptions. Based on the results of this analysis, no credit losses were projected. Management's analysis of the credit characteristics of individual securities and the underlying collateral and levels of subordination for eachcontinues to provide more than sufficient coverage of stress scenario collateral losses, further supporting our determination that none of our securities are credit loss impaired. The scenario used to project stress scenario losses is generally calibrated to the single family rental real estate-backed securitieslevel of stress experienced in unrealized loss positions is not indicative of projected credit losses. Management's analysis of the state and municipal obligations in unrealized loss positions included reviewing the ratings of the securities and the results of credit surveillance performed by an independent third party. Given the expectation of timely repayment of principal and interest and the generally limited severity of impairment, the impairments were considered to be temporary.

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 monthlyquarterly basis. Any price evidencing unexpected monthquarter over monthquarter fluctuations or deviations from our expectations based on recent observed trading activity and other information available in the marketplace that would impact the value of the security is challenged. Responses to the price challenges, which generally include specific information about inputs and assumptions incorporated in the valuation and their sources, are reviewed in detail. If considered necessary to resolve any discrepancies, a price will be obtained from an additional independent valuation specialist.sources. We do not typically adjust the prices provided, other than through this established challenge process. Our primary pricing services utilize observable inputs when available, and employ unobservable inputs and proprietary models only when observable inputs are not available. As a matter of course, the services validate prices by comparison to recent trading activity whenever such activity exists. Quotes obtained from the pricing services are typically non-binding.
We have also established a quarterly price validation process to assess the propriety of the pricing methodologies utilized by our primary pricing services by independently verifying the prices of a sample of securities in the portfolio. Sample sizes vary based on the type of security being priced, with higher sample sizes applied to more difficult to value security types. Verification procedures may consist of obtaining prices from an additional outside source or internal modeling, generally based on Intex. We have established acceptable percentage deviations from the price provided by the initial pricing source. If deviations fall outside the established parameters, we will obtain and evaluate more detailed information about the assumptions and inputs used by each pricing source or, if considered necessary, employ an additional valuation specialist to price the security in question. Pricing issues identified through this evaluation are addressed with the applicable pricing service and methodologies or inputs are revised as determined necessary. Depending on the results of the validation process, sample sizes may be extended for particular classes of securities. Results of the validation process are reviewed by the treasury front office and by senior management.

The majority of our investment securities are classified within level 2 of the fair value hierarchy. U.S. Treasury securities and certain preferred stocksmarketable equity securities are classified within level 1 of the hierarchy. At September 30, 2017 and December 31, 2016, 1.0% and 2.1%, respectively, of our investment securities were classified within level 3 of the fair value hierarchy. Securities classified within level 3 of the hierarchy at September 30, 2017 included certain private label residential MBS and trust preferred securities. These securities were classified within level 3 of the hierarchy because proprietary assumptions
For additional disclosure 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.

Residential mortgages and other consumer loans

Residential mortgages and other consumer loans totaled $4.5 billion, or 22.0% of total loans, at September 30, 2017 and $4.1 billion, or 21.0% of total loans, at December 31, 2016.
The non-covered residential loan portfolio is primarily comprised of loans purchased on a national basis through established correspondent channels. The portfolio also includes loans originated through retail channels in our Florida and New York geographic footprint prior to the termination of our retail residential mortgage origination business in early 2016. Non-covered residential mortgage loans are primarily closed-end, first lien jumbo mortgages for the purchase or re-finance of owner occupied property. The loans have terms ranging from 10 to 30 years, with either fixed or adjustable interest rates. At September 30, 2017, $113 million or 2.8% of non-covered residential mortgage loans were interest-only loans, substantially all of which begin amortizing 10 years after origination.
We do not originate or acquire option ARMs, “no-doc” or “reduced-doc” mortgages and do not utilize wholesale mortgage origination channels although the covered loan portfolio contains loans with these characteristics. The Company’s exposure to future losses on these mortgage loans is mitigated by the Single Family Shared-Loss Agreement.

Equipment with a carrying value of $288 million at September 30, 2017 was leased to companies for use in the energy industry.

Asset Quality
In discussing asset quality, we distinguish between covered loans and non-covered loans. Although the risk profile of covered loans is higher than that of non-covered loans, our exposure to loss related to covered loans is significantly mitigated by the fair value basis recorded in these loans resulting from the application of acquisition accounting and by the Single Family Shared-Loss Agreement. At September 30, 2017, residential loans covered under the Single Family Shared-Loss Agreement totaled $538 million.Commercial Loans
We have established a robust credit risk management framework, put in place an experienced team to lead the workout and recovery process for the commercial and commercial real estate portfolios and implemented a dedicated internal credit review function. We have an experienced resolution team in place for covered residential mortgage loans, and have implemented outsourcing arrangements with industry leading firms in certain areas such as OREO resolution. 
Loan performance is monitored by our credit administration, portfolio management and workout and recovery departments. Generally,Risk ratings are updated continuously; generally, commercial relationships with balances in excess of defined thresholds are re-evaluated at least annually and more frequently if circumstances indicate that a change in risk rating may be warranted. The defined thresholds range from $1 million to $3 million. Additionally,Homogenous groups of smaller balance commercial loans may be monitored collectively. The credit quality and risk rating of commercial loans as well as our underwriting and portfolio management practices are regularly reviewed by our internal independent credit review department.
We believe internal risk rating is the best indicator of the credit quality of commercial loans. The Company utilizes a 13 grade16-grade internal asset risk classification system as part of its efforts to monitor and maintain commercial asset quality. LoansThe special mention rating is considered a transitional rating for loans exhibiting potential credit weaknesses that deserve management’s close attention and that if left uncorrected maycould result in deterioration of the repayment capacity of the borrower are categorized as special mention.prospects at some future date if not checked or corrected and that deserve management’s close attention. These borrowers may exhibit negative financial trendsdeclining cash flows or erratic financial performance, strained liquidity, marginal collateral coverage, declining industry trendsrevenues or weak management.increasing leverage. Loans with well-defined credit weaknesses that may result in a loss if the deficiencies are not corrected are assigned a risk rating of substandard. These borrowers may exhibit payment defaults, inadequate cash flows from current operations, operating losses, increasing balance sheet leverage, project cost overruns, unreasonable construction delays, exhausted interest reserves, declining collateral values, frequent overdrafts or past due real estate taxes. Loans with weaknesses so severe that collection in full is highly questionable or improbable, but because of certain reasonably specific pending factors have not been charged off, are assigned an internal risk rating of doubtful.
Residential mortgage loans and consumer loans are not individually risk rated. Delinquency status is the primary measure we use to monitor the credit quality of these loans. We also consider original LTV and FICO score to be significant indicators of credit quality for the non-covered 1-4 single family residential portfolio.

Although our assessment is ongoing and the results of that assessment are subject to change in the future, we do not currently believe the ability of the substantial majority of our borrowers to repay their loans or the value of the collateral securing those loans has been materially impacted by Hurricanes Irma and Harvey.
Non-covered Loans and Leases
Commercial Loans
The ongoing asset quality of significant commercial loans is monitored on an individual basis through our regular credit review and risk rating process.

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 forrisk ratings.

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 millionthousands).
In the aggregate, the ALLL related to taxi medallion loans was 10.9% of the outstanding balance at September 30, 2017, compared to 6.0% at December 31, 2016. Charge-offs of $35.3 million and $47.1 million were recognized in the three and nine months ended September 30, 2017 related to taxi medallion loans.
We are no longer originating new taxi medallion loans. Our portfolio management strategies include, but are not limited to, working with borrowers experiencing cash flow challenges to provide short term relief and/or extended amortization periods, pro-actively attempting to refinance loans prior to maturity, continuing to monitor industry data and obtaining updated borrower and guarantor financial information. As taxi medallion loans approach maturity or are refinanced, we expect the number and amount of TDRs in this portfolio segment to continue to increase.
Hurricane Impact - Commercial Loans
Commercial loans totaling $1.9 million and $19.4 million had been modified or granted temporary payment deferrals as of September 30, 2017 and October 31, 2017, respectively, related to the recent hurricanes. Of these modifications and deferrals, none were determined to be TDRs due to the generally insignificant nature of the payment delays.
As of September 30 and October 31, 2017, respectively, commercial loans to borrowers that have significant business operations in or are secured by collateral in areas impacted by Hurricanes Irma and Harvey totaling approximately $4.7 million and $21.3 million were more than 30 days past due; $3.7 million All of these loans were more than 30 days past due prior toare performing. Non-performing loans are discussed further in the storms. Approximately $22.2 million of commercial loans have been downgraded to criticized or classified status through October 31, 2017 as a result of the impact of the storms.section entitled "Non-performing Assets" below.

Four operating lease relationships with assets under lease with a carrying value totaling $81 million, of which $75 million were exposures to the energy industry, were internally risk rated special mention or substandard at September 30, 2017. The present value of remaining lease payments on these leases totaled approximately $22 million at September 30, 2017, of which $17 million were exposures to the energy industry. There have been no missed payments related to the operating lease portfolio to date. One relationship has been restructured to date, with no decrease in total minimum lease payments.

Railcars are long-lived equipment with useful lives of approximately 35-50 years. The equipment is leased to commercial end-users with original lease terms generally ranging from 3-9 years at September 30, 2017. We are exposed to the risk that,classified CRE loans by property type at the end of the lease term, the value of the asset will be lower than expected, potentially resulting in reduced future lease incomedates indicated (in millions):

(1)Includes Pinnacle and managed by a dedicated internal staff of asset managers, managed by seasonedfranchise and 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, including lease administration and reporting, a Regulation Y compliant full service maintenance program and railcar re-marketing. Risk is managed by setting appropriate residual values at inception and systematic reviews of residual values based on independent appraisals, performed at least annually. Additionally, our internal management team and our external service provider closely follow the rail markets, monitoring traffic flows, supply and demand trends and the impact of new technologies and regulatory requirements. Demand for railcars is sensitive to shifts in general and industry specific economic and market trends and shifts in trade flows from specific events such as natural or man-made disasters. We seek to mitigate these risks by leasing to a stable end-user base, by maintaining a relatively young and diversified fleet of assets that are expected to maintain stronger and more stable utilization rates despite impacts from unexpected events or cyclical trends and by staggering lease maturities. We regularly monitor the impact of 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

In general, we purchase performing jumbo mortgage loans which havewith FICO scores above 700, primarily are owner-occupied and full documentation, and have awith current LTVLTV's of 80% or less although loansless. Loans with LTVs higher than 80% may be extended to selected credit-worthy borrowers. We perform due diligence on the purchased loans for credit, compliance, counterparty, payment history and property valuation.

Covered Loans
At September 30, 2017, residential ACI loans totaled $476 million and residential non-ACI loans totaled $62 million, including premiums, discounts and deferred fees and costs. All of these loans are covered under the Single Family Shared-Loss Agreement.
Covered residential loans were placed into homogenous pools at the time of the FSB Acquisition and the ongoing credit quality and performance of these loans is monitored on a pool basis. We monitor the pools quarterly to determine whether any changes have occurred in expected cash flows that would be indicative of impairment or necessitate reclassification between non-accretable difference and accretable yield. At September 30, 2017, accretable yield on residential ACI loans totaled $511 million and non-accretable difference related to those loans totaled $227 million.
At September 30, 2017, the recorded investment in non-ACI 1-4 single family residential loans was $24.6 million; $1.6 million or 6.6% of these loans were 30 days or more past due and $0.9 million or 3.8% of these loans were 90 days or more past due. At September 30, 2017, 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.
Home equity lines of credit generally provide that payment terms be reset after an initial contractual period of interest only payments, requiring the pay down of principal through balloon payments or amortization. Additional information regarding ACI and non-ACI home equity lines of credit at September 30, 2017 is summarized as follows:
 ACI Non-ACI
Loans resetting from interest only:

First liens10.3% 18.8%
Second or third liens89.7% 81.2%
 100.0% 100.0%
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 equity 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 ACIPCD loans for which management has a reasonable basis for an expectation about future cash flows and government insured residential loans, and (iii) OREO and repossessedother non-performing 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.

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. New and non-ACI residential and consumerResidential loans, other than government insured pool buyout loans, are generally placed on non-accrual status when 90they are 60 days of interest is due and unpaid.past due. Additionally, certain residential loans not contractually delinquent but in forbearance may be placed on non-accrual status at management's discretion. 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 9060 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.
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.

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. 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.

Criticized or classified commercial loans in excess of certain thresholds are reviewed quarterly by the Criticized Asset Committee, which determinesevaluates the appropriate strategy for collection to mitigate the amount of credit losses.losses and considers the appropriate risk rating for these loans. Criticized asset reports for each relationship are presented by the assigned relationship manager and credit officer to the Criticized Asset Committee until such time as the relationships are returned to a satisfactory credit risk rating or otherwise resolved. The Criticized Asset Committee may require the transfer of a loan to our workout and recovery department, which is tasked to effectively manage the loan with the goal of minimizing losses and expenses associated with restructure, collection and/or liquidation of collateral. Commercial loans with a risk rating of substandard; impairedsubstandard, loans on non-accrual status; loans modified as TDRs; taxi medallion loans; orstatus, and assets classified as OREO or repossessed assets are usually transferred to workout and recovery. Oversight of the workout and recovery department is provided by the Criticized Asset Recovery Committee.
WeOur servicers evaluate each residential loan in default to determine the most effective loss mitigation strategy, which may be modification, short sale, or foreclosure. Throughforeclosure, and pursue the program's expiration on December 31, 2016, we offered loan modifications under the HAMP program to eligible borrowers in the residential portfolio. HAMP is a uniform loan modification process that provides eligible borrowers with sustainable monthly mortgage payments equal to a target 31% of their gross monthly income. We began offering a new modification program in late 2016 modeled after the FNMA standard modification program.
In additionalternative most suitable to the modification programs discussed above, we offer a proprietary Subordinate Lien Modification Program for home equity loansconsumer and lines of credit. This provides BankUnitedto mitigate losses to the ability to offer a modification on loans covered under the Single Family Shared-Loss Agreement that are subordinate to either a BankUnited first lien or a first lien from another lender.Bank.

Analysis of the Allowance for Loan and LeaseCredit Losses
The ALLL relates to (i) new loans, (ii) estimated additional losses arising on non-ACI loans subsequent to the FSB Acquisition, and (iii) impairment recognized as a result of decreases in expected cash flows on ACI loans due to further credit deterioration. The impact of any additional provision for losses on covered loansACL is significantly mitigated by an increase in the FDIC indemnification asset. The determinationmanagement's estimate of the amount of expected credit losses over the ALLLlife of the loan portfolio, or the amount of amortized cost basis not expected to be collected, at the balance sheet date. This estimate encompasses information about historical events, current conditions and reasonable and supportable economic forecasts. Determining the amount of the ACL is by nature, highly complex and subjective. Future eventsrequires extensive judgment by management about matters that are inherently uncertain could result in material changes to theuncertain. Given a level of continued uncertainty about the ALLL. Generalgeneral economy, evolving dynamics in some segments of the commercial real estate market, particularly the office sector, the complexity of the ACL estimate and level of management judgment required, we believe it is possible that the ACL estimate could change, potentially materially, in future periods. If commercial real estate market dynamics in our primary markets worsen beyond our current expectations, the ACL and the provision for credit losses will increase in the future. Changes in the ACL may result from changes in current economic conditions including but not limited to unemploymentunanticipated changes in interest rates the level of business investmentor inflationary pressures, changes in our economic forecast, loan portfolio composition, commercial and growth,residential real estate values, vacancy ratesmarket dynamics and rental rates in our primary market areas, the level of interest rates, and a variety of other factorscircumstances not currently known to us that affect the ability of borrowers’ businesses to generate cash flows sufficient to service their debts willmay impact the future performancefinancial condition and operations of the portfolio. our borrowers, among other factors.
New and non-ACILoans
Residential and other consumer
Due to the lack of similarity between the risk characteristics of new loans and covered loans in the residential and home equity portfolios, management does not believe it is appropriate to use the historical performance of the covered residential mortgage portfolio asExpected credit losses are estimated on a collective 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 comparabilitygroups of FICO scores and LTV ratios between loans included in those securitizations and loans in the Bank’s portfolio and the geographic diversity in the new purchased residential portfolio, we determined that prime residential mortgage securitizations provide an appropriate proxy for incurred losses in this portfolio class. A peer group 16-quarter average net charge-off 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.
Based on an analysis of historical performance, OREO and short sale losses, recent trending data and other internal and external factors, we have concluded that historical performance by portfolio class is the best indicator of incurred loss for the non-ACI 1-4 single family residential and home equity portfolio classes. For each of these portfolio classes, a quarterly roll rate matrix is calculated by delinquency bucket to measure the rate at which loans move from one delinquency bucket to the next during a given quarter. An average 16-quarter roll rate matrix is used to estimate the amount within each delinquency bucket expected to roll to 120+ days delinquent. We assume no cure for those loans that are currently 120+ days delinquent. Loss severity given default is estimated based on internal data about OREO sales and short sales from the portfolio. The ALLL calculation incorporates a 100% loss severity assumption for home equity loans that are projected to roll to default. For non-ACI residential loans, the allowance is initially calculated based on UPB. The total of UPB less the calculated allowance is then compared to the carrying amount of the loans, net of unamortized credit related fair value adjustments established at acquisition. If the calculated balance net of the allowance is less than the carrying amount, an additional allowance is established. Any increase or decrease in the allowance for non-ACI residential loans will result in a corresponding increase or decrease in the FDIC indemnification asset. 
Commercial
The allowance is comprised of specific reserves for loans that are individually evaluated and determined to be impaired as well as general reserves for loans that have not been identified as impaired.
Commercial relationships graded substandard or doubtful and on non-accrual status with committed credit facilities greater than or equal to $1.0 million as well as loans modified in TDRs are individually evaluated for impairment. Other commercial

relationships on non-accrual status with committed balances under $1.0 million may also be evaluated for impairment, at management's discretion. For loans evaluated individually for impairment and determined to be impaired, a specific allowance is established based on the present value of expected cash flows discounted at the loan’s effective interest rate, the estimated fair value of the loan, or the estimated fair value of collateral less costs to sell. We recognized partial charge-offs at September 30, 2017 on taxi medallion loans all of which are risk-rated substandard and on non-accrual status, as necessary to reduce the carrying value of the loans to our estimate of the value of New York City taxi medallions based on our cash flow template. Additionally, a specific allowance was recognized equal to the amount by which each loan exceeded 85% of the estimated value, in recognition of the continued declining trend in cash flows and lower prices observed on certain recent taxi medallion transfers. The amount of this specific allowance was determined based on management's judgment.
We believe that loans rated special mention, substandard or doubtful that are not individually evaluated for impairment exhibit characteristics indicative of a heightened level of credit risk. We apply a quantitative loss factor for loans rated special mention based on average annual probability of default and implied severity, derived from internal and external data. Loss factors for substandard and doubtful loans that are not individually evaluated are determined by using default frequency and severity information applied at the loan level. Estimated default frequencies and severities are based on available industry data. In addition, we apply a floor to these calculated loss factors, based on the loss factor applied to the special mention portfolio.
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 creditshare similar 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.
characteristics. For loans that do not share similar risk characteristics with other loans such as collateral dependent loans, expected credit losses are partially guaranteed byestimated on an individual basis. Expected credit losses are estimated over 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 andcontractual terms of the loans, specifically including the volumeadjusted for expected prepayments, generally excluding expected extensions, renewals, 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.
ACILoansmodifications.
For ACIthe substantial majority of portfolio segments and subsegments, including residential loans a valuation allowance is established when periodic evaluations ofother than government insured loans, and most commercial and commercial real estate loans, 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 flowslosses 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 a pool basis for ACI 1-4 single family residentialthe reasonable and home equity loans. The analysis of expected pool cash flows incorporates updatedsupportable economic forecast. Projected PDs and LGDs, determined based on pool level characteristics, are applied to estimated exposure at default, considering the contractual term and payment structure of loans, adjusted for 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 loansprepayments, 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 underlyinggenerate estimates of expected cash flowsloss. For criticized or classified loans, PDs are adjusted to benchmark PDs established for ACI commercial loans are defaulteach risk rating. The ACL estimate incorporates a reasonable and supportable economic forecast through the use of externally developed macroeconomic scenarios applied in the models.
A single economic scenario or a probability weighted blend of economic scenarios may be used. The models ingest numerous national, regional and severity of loss given default. Assessments of default probabilityMSA level variables 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 ordata points. At March 31, 2024 and December 31, 2016. 2023, we used a combination of weighted third-party provided economic scenarios in calculating the quantitative portion of the ACL. Each of these externally provided scenarios in fact represents the result of a probability weighting of thousands of individual scenario paths.

Excludingincrease in the $5.0 million unallocated qualitative allowance relative to the impact of the hurricanes, the balance of the ALLL for non-covered loans at September 30, 2017 decreased slightly as compared toACL from December 31, 2016. Decreases in quantitative loss factors applied2023, to the majority of the commercial loan portfolio and net decreases in qualitative factorsMarch 31, 2024, were substantially offset by the impact of the growth of the loan portfolio and(i) an increase in reserves for criticized and classified loans, including taxi medallion loans. Factors influencing the change in the ALLL related to specific loan types at September 30, 2017 as compared to December 31, 2016, include:
The ALLL related to non-covered 1-4 single family residential loans did not change significantly. Increases related to growth in the corresponding portfolio were substantially offset by declines in both the applicable quantitative historical loss rate and qualitative reserves.
A decrease of $3.3 million for multi-family loans primarily reflects decreases in quantitative loss factors, the decline in the corresponding portfolio and a net decrease in qualitative loss factors, offset in part by an increase in criticizedwith the majority related to office CRE and classified loans.
An increase of $3.9 million for non-owner occupied commercial real estate loans was primarily driven by the growth of the corresponding portfolio and an increase in criticized and classified loans,(ii) risk rating migration, partially offset by a decrease(iii) an overall improvement in quantitative loss factors.
An increasecurrent economic conditions and the economic forecast. At March 31, 2024, the ratio of $3.7 million for owner occupied commercial real estatethe ACL to loans was primarily attributable0.90% compared to increases0.82% at December 31, 2023. The ACL to loans ratio for commercial portfolio sub-segments including C&I, CRE, and franchise and equipment finance was 1.42% at March 31, 2024 and the ACL to loans ratio for CRE office loans was 2.26%. Further discussion of changes in specific reservesthe ACL for impaired loans and to a lesser extent,select portfolio sub-segments follows:
The ACL for the growth of the corresponding portfolio.
An increase of $2.5CRE portfolio sub-segment increased by $19.7 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 ninethree months ended September 30, 2017.
A decreaseMarch 31, 2024, from 0.71% to 1.05% of $0.8 millionloans. The most significant reasons 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 growththe increase in the corresponding portfolio.
A $8.0 million decreaseACL for commercial lending subsidiaries primarily reflects decreases in quantitative loss factors for the municipal finance receivables and decreasesthis segment were an increase in qualitative loss factors, related primarily to portfoliooffice CRE, and risk rating migration.

For the commercial and industrial sub-segment, including owner-occupied commercial real estate, the ACL coverage ratio increased from 1.60% to 1.62% of loans. This increase was primarily driven by risk rating migration and qualitative loss factors, partially offset by an improved economic forecast.
The ACL for the residential segment decreased by $1.0 million during the three months ended March 31, 2024, from 0.09% to 0.08% of loans primarily due to the improved economic forecast.
The estimate of the ACL at March 31, 2024, was informed by forecasted economic scenarios published in March 2024, a wide variety of additional economic data, information about borrower financial condition and collateral values and other relevant information. The quantitative portion of the ACL at March 31, 2024, was modeled using a weighting of baseline, downside and upside third-party economic scenarios, with the highest weighting ascribed to the baseline scenario and lower weightings ascribed equally to the downside and upside scenarios. The economic variables that impacted the ACL for the three months ended March 31, 2024, included assumptions about interest rates and spreads, commercial property forecasts, the forecasted trajectory of regional unemployment and performance of the stock market.
Some of the high level data points informing the baseline scenario, which was the scenario most heavily weighted, used in estimating the quantitative portion of the ACL at March 31, 2024, included:
Labor market assumptions, which reflected national unemployment peaking at 4.1% and
Annualized growth trendsin national GDP troughing at 1.3% in the baseline.
The above unemployment and credit concentrations.
GDP growth assumptions are provided to give a high level overview of the nature and severity of the baseline economic forecast scenario used in estimating the ACL. Numerous additional variables and assumptions not explicitly stated, including but not limited to detailed commercial property forecasts, projected stock market volatility indices and a variety of assumptions about market interest rates and spreads also contributed to the overall impact economic conditions and the economic forecast had on the ACL estimate. Furthermore, while the variables presented above are at the national level, most of the economic variables are regionalized at the market and submarket level in the models.

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

Liquidity and Capital Resources
Liquidity
Liquidity involves our ability to generate adequate funds to support planned interest earning asset growth, meet deposit withdrawal and credit line usage requests in both normal operating and stressed environments, maintain reserve requirements, conduct routine operations, pay dividends, service outstanding debt and meet other contractual obligations.
BankUnited's ongoing liquidity needs have historically been met primarily by cash flows from operations, deposit growth, the investment portfolio, its amortizing loan portfolio and FHLB advances. FRB discount window borrowings, repurchase agreement capacity and a letter of credit with the FHLB provide additional sources of contingent liquidity. For the three months ended March 31, 2024 and 2023, net cash provided by operating activities was $66 million and $141 million, respectively.
Same day available liquidity includes cash, secured funding such as borrowing capacity at the Federal Home Loan Bank of Atlanta and the Federal Reserve, and unencumbered securities. Additional sources of liquidity include cash flows from operations, wholesale deposits, cash flow from the Bank's amortizing securities and loan portfolios, and the sale of investment securities. Management also has the ability to exert substantial control over the rate and timing of loan production, and resultant requirements for liquidity to fund new loans.

Same Day Available Liquidity
2904
At March 31, 2024, the Bank had total same day available liquidity of approximately $14.8 billion, consisting of cash of $407 million, borrowing capacity at the Federal Home Loan Bank of $5.9 billion, borrowing capacity at the FRB of $7.2 billion and unencumbered securities of $1.2 billion. The increase in same day available liquidity as compared to December 31, 2023 reflected the decline in outstanding FHLB advances, increasing FHLB capacity. At March 31, 2024, the ratio of estimated insured and collateralized deposits to total deposits was 65%, compared to 66% at December 31, 2023, and the ratio of available liquidity to estimated uninsured, uncollateralized deposits was 156% compared to 152% at December 31, 2023. As a commercially focused bank, due to the inherent nature of commercial deposits, a significant portion of our deposits are uninsured. We continue to market and educate our customers about products that enable them to obtain FDIC insurance on certain deposits exceeding the standard single depositor insurance limit, have implemented single depositor concentration limits and reduced or eliminated exposure to sectors or depositors that evidenced higher volatility following the events of early 2023.
Our ALM policy establishes limits or operating risk thresholds for a face amountnumber of $400 million,measures of liquidity which are monitored at least monthly by the ALCO and quarterly by the Board of Directors. Some of the measures currently used to dimension liquidity risk and manage liquidity are the ratio of available liquidity to uninsured/non-collateralized deposits, the ratio of wholesale funding to total assets, the ratio of available operational liquidity (which excludes availability at the FRB) to volatile liabilities, a fixed coupon rateliquidity stress test coverage ratio, the loan to deposit ratio, a one-year liquidity ratio, a measure of 4.875%available on-balance sheet liquidity, the ratio of FHLB advances to total assets, large depositor concentrations and mature on November 17, 2025.the ratio of non-interest bearing deposits to total deposits, which is reflective of the quality and cost, rather than the quantity, of available liquidity. We also have single depositor relationship limits.

As a holding company, BankUnited, Inc. is a corporation separate and apart from its banking subsidiary, and therefore, provides for its own liquidity. BankUnited, Inc.’s main sources of funds include management fees and dividends from the Bank, access to capital markets and, to a lesser extent, its own securities portfolio. There are regulatory limitations that may affect the ability of the Bank to pay dividends to BankUnited, Inc. Management believes that such limitations will not impact our ability to meet our ongoing near-term cash obligations.
Capital Resources
Pursuant to the FDIA, the federal banking agencies have adopted regulations setting forth a five-tier system for measuring the capital adequacy of the financial institutions they supervise. At September 30, 2017March 31, 2024 and December 31, 2016, BankUnited2023, the Company and the CompanyBank had capital levels that exceeded both the regulatory well-capitalized guidelines and all internal capital ratio targets.
Stockholders' equity increased Upon adoption of ASU 2016-13 on January 1, 2020, the Company elected the option to $2.6 billion at September 30, 2017, an increasetemporarily delay the effects of $205 million, or 8.5%, from December 31, 2016, due primarily to the retention of earnings and the exercise of stock options resulting in proceeds of $61.5 million during theCECL on regulatory capital for two years, followed by a three-year transition period.
Since our formation, stockholders' equity has been impacted primarily by the retention of earnings, and to a lesser extent, proceeds from the issuance of common shares and changes in unrealized gains and losses, net of taxes, on investment securities

available for sale and cash flow hedges. Our rate of earnings retention is derived by dividing undistributed earnings per common share by earnings per common share. Our retention ratio was 66.0% and 64.9% for the three and nine months ended September 30, 2017, respectively, compared to 55.7% and 58.4% for the three and nine months ended September 30, 2016, respectively. We retain a high percentage of our earnings to support our planned growth.
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.

(1)There is no Tier 1 leverage ratio component in the definition of a well-capitalized bank holding company.
Levels of capital required to be well capitalized or adequately capitalized as reflected above do not include a capital conservation buffer that is being phased in beginning in 2016. When fully phased in on January 1, 2019, the Bank and the Company will have to maintain this capital conservation buffer composed of CET1 capital equal to 2.50% of risk-weighted assets above the amounts required to be adequately capitalized, as reflected above, in order to avoid limitations on capital distributions, including dividend payments and certain discretionary bonus payments to executive officers. Capital ratios required to be considered well-capitalized exceed the ratios required under the capital conservation buffer requirement at September 30, 2017.

Liquidity

Liquidity involves our ability to generate adequate funds to support planned interest earning asset growth, meet deposit withdrawal requests, maintain reserve requirements, conduct routine operations, pay dividends, service outstanding debt and meet other contractual obligations.
Primary sources of liquidity include cash flows from operations, cash generated by the repayment and resolution of covered loans, cash payments received from the FDIC pursuant to the Single Family Shared-Loss Agreement, deposit growth, the available for sale securities portfolio and FHLB advances.
For the nine months ended September 30, 2017 and 2016, net cash provided by operating activities was $231.2 million and $227.3 million, respectively. Accretion on ACI loans, which is reflected as a non-cash reduction in net income to arrive at operating cash flows, totaled $226.3 million, and $228.5 million for the nine months ended September 30, 2017 and 2016, respectively. Accretable yield on ACI loans represents the excess of expected future cash flows over the carrying amount of the loans, and is recognized as interest income over the expected lives of the loans. Amounts recorded as accretion are realized in cash as individual loans are paid down or otherwise resolved; however, the timing of cash realization may differ from the timing of income recognition. These cash flows from the repayment or resolution of covered loans, inclusive of amounts that have been accreted through earnings over time, are recognized as cash flows from investing activities in the consolidated statements of cash flows upon receipt. Cash payments from the FDIC in the form of reimbursements of losses related to the

covered loans under the Single Family Shared-Loss Agreement are also characterized as investing cash flows. Cash generated by the repayment and resolution of covered loans and reimbursements from the FDIC totaled $348.5 million and $430.3 million for the nine months ended September 30, 2017 and 2016, respectively. Both cash generated by the repayment and resolution of covered loans and cash payments received from the FDIC have been and are expected to continue to be, although to a lesser extent in the future, consistent and relatively predictable sources of liquidity.
In addition to cash provided by operating activities, the repayment and resolution of covered loans and payments under the Single Family Shared-Loss Agreement from the FDIC, BankUnited’s liquidity needs, particularly liquidity to fund growth of interest earning assets, have been and continue to be met by deposit growth and FHLB advances. The investment portfolio also provides a source of liquidity.
BankUnited has access to additional liquidity through FHLB advances, other collateralized borrowings, wholesale deposits or the sale of available for sale securities. At September 30, 2017, unencumbered investment securities available for sale totaled $4.3 billion. At September 30, 2017, BankUnited had available borrowing capacity at the FHLB of $3.8 billion, unused borrowing capacity at the FRB of $544 million and unused Federal funds lines of credit totaling $70 million. Management also has the ability to exert substantial control over the rate and timing of growth of the non-covered loan portfolio, and resultant requirements for liquidity to fund loans.
Continued runoff of the covered loan portfolio and FDIC indemnification asset and growth of deposits and the non-covered loan portfolio are the most significant trends expected to impact the Bank’s liquidity in the near term.
The ALCO policy has established several measures of liquidity which are monitored monthly by the ALCO and quarterly by the Board of Directors. One primary measure of liquidity monitored by management is the 30 day total liquidity ratio, defined as (a) the sum of cash and cash equivalents, pledgeable securities and a measure of funds expected to be generated by operations over the next 30 days; divided by (b) the sum of potential deposit runoff, liabilities maturing within the 30 day time frame and a measure of funds expected to be used in operations over the next 30 days. BankUnited’s liquidity is considered acceptable if the 30 day total liquidity ratio exceeds 100%. At September 30, 2017, BankUnited’s 30 day total liquidity ratio was 172%. Management also monitors a one year liquidity ratio, defined as (a) cash and cash equivalents, pledgeable securities, unused borrowing capacity at the FHLB, and loans and non-agency securities maturing within one year; divided by (b) forecasted deposit outflows and borrowings maturing within one year. Forecasted deposit outflows, excluding certificate of deposits, are based on runoff rates derived from the most recent external core deposit analysis obtained by the Company. This ratio allows management to monitor liquidity over a longer time horizon. The acceptable threshold established by the ALCO for this liquidity measure is 100%. At September 30, 2017, BankUnited’s one year liquidity ratio was 158%. Additional measures of liquidity regularly monitored by the ALCO include the ratio of wholesale funding to total assets, a measure of available liquidity to volatile liabilities and the ratio of brokered deposits to total deposits. At September 30, 2017, BankUnited was within acceptable limits established by the ALCO and the Board of Directors for each of these measures.
As a holding company, BankUnited, Inc. is a corporation separate and apart from its banking subsidiary, and therefore, provides for its own liquidity. BankUnited, Inc.’s main sources of funds include management fees and dividends from the Bank, access to capital markets and, to a lesser extent, its own available for sale securities portfolio. There are regulatory limitations that affect the ability of the Bank to pay dividends to BankUnited, Inc. Management believes that such limitations will not impact our ability to meet our ongoing near-term cash obligations.
We expect that our liquidity requirements will continue to be satisfied over the next 12 months through the sources of funds described above.
Interest Rate Risk
TheA principal component of the Company’s risk of loss arising from adverse changes in the fair value of financial instruments, or market risk, is interest rate risk, including the risk that assets and liabilities with similar re-pricing characteristics may not reprice at the same time or to the same degree. A primary objective of the Company’s asset/liability management activities is to maximize net interest income, while maintaining acceptable levels of interest rate risk. The ALCO is responsible for establishing policies to limitmanage exposure to interest rate risk, and to ensure procedures are established to monitor compliance with these policies. The guidelinespolicies established by the ALCO are approved at least annually by the Board of Directors.Directors or its Risk Committee.
Management believes that the simulation of net interest income in different interest rate environments provides the most meaningful measure of interest rate risk. Income simulation analysis is designed to capture not only the potential of all assets and liabilities to mature or reprice, but also the probability that they will do so. Income simulation also attends to the relative interest rate sensitivities of these items, and projects their behavior over an extended period of time. Finally, income simulation

permits management to assess the probable effects on the balance sheet not only of changes in interest rates, but also of proposed strategies for responding to them. Simulation of changes in EVE in various interest rate environments is also a meaningful measure of interest rate risk.
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 a consensus forward interest rate curvescurve versus net interest income in alternative rate scenarios. Simulations are generated based on both static and dynamic balance sheet assumptions. Management continually reviews and refines its interest rate risk management process in response to changes in the interest rate environment, the economic climate and economic climate.observed customer behavior. Currently, our model projects a down 100, plus 100, plus 200 and plus 300 basis point change with rates increasing by the magnitude of theinterest rate ramp evenly over the next 12 months as well as flattening yield curve scenarios andrisk management policy framework is based on modeling instantaneous rate shocks to a static balance sheet, assuming that maturing instruments are replaced with like instruments at forward rates, of downplus and minus 100, plus 100, plus 200, 300 and plus 300400 basis point parallel shifts. In lower interest rate environments, we may not model more extreme declining rate scenarios and in certain macro-environments, we may model shocks of more than 400 basis points. Our ALM policy has established limits for the plus and minus 100 and 200 basis points shock scenarios. We also model a variety of dynamic balance sheet scenarios, various yield curve slopes, non-parallel shifts and alternative depositor behavior, beta and decay assumptions. We continually evaluate the scenarios being modeled with a view toward adapting them to changing economic conditions, expectations and trends.
The Company’s ALCO policy provides that net interest income sensitivity will be considered acceptable if decreases in forecast net interest income, based on a dynamic forecasted balance sheet, in specified rate shock scenarios are within specified percentages of forecast net interest income in the most likely rate scenario over the next twelve months and in the second year. The following table illustrates the acceptable limits as defined by policy andpresents the impact on forecasted net interest income of down 100, plus 100, plus 200 and plus 300 basis pointcompared to a "most likely" scenario, based on the consensus forward curve, in static balance sheet, parallel rate shock scenarios at September 30, 2017 and December 31, 2016:

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 six rate scenarios, derived by implementing immediate parallel movements of plus and minus 100 200 and 300 basis points from current rates. We did not simulate decreases in interest rates greater than 100200 basis points at September 30, 2017 due to the current low rate environment. March 31, 2024 and December 31, 2023:

All of September 30, 2017, our simulation for the Company indicated percentage changes from base EVE of 1.7%, (3.6)%, (7.9)% and (12.7)% in down 100, plus 100, plus 200 and plus 300 basis point scenarios, respectively.
These measures fallmodeled results at March 31, 2024, are within an acceptable level of interest rate risk per the policies established by the ALCO and the Board of Directors. In the event the models indicate an unacceptable level of risk, the Company could undertake a number of actions that would reduce this risk, including the sale or re-positioning of a portion of its available for sale investment portfolio, restructuring of borrowings, or the use of derivatives such as interest rate swaps and caps.
ALM policy limits. Many assumptions were used by the Company to calculate the impact of changes in interest rates on forecasted net interest income and EVE, 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, unanticipated 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.conditions or changes in balance sheet composition.
Derivative Financial Instruments and Hedging Activities
Management continually evaluates a variety of hedging strategies that are available to manage interest rate risk. In the current environment, we continue to evaluate potential hedging strategies to mitigate risk from a period of rapid or extreme declines in rates.
Interest rate swapsderivatives designated as cash flow or fair value hedging instruments are one of the tools we use to manage interest rate risk. These derivative instruments are used to mitigate exposure to changes in interest ratescash flows on variable rate borrowings suchliabilities and to changes in the fair value of fixed rate financial instruments, in each case caused by fluctuations in benchmark interest rates, as FHLB advances andwell as to manage duration of liabilities.

During the three months ended March 31, 2024, no director or officer (as defined in addition to the following factor.
A significant portion of our loans are to borrowers whose businesses are located in or secured by properties located in the state of Florida, which was impacted by Hurricane Irma. In addition, the Bank 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.
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 abilityExchange Act Rule 16a-1(f)) of the substantial majorityCompany adopted or terminated a “Rule 10b5-1 trading arrangement” or “non-Rule 10b5-1 trading arrangement,” as each term is defined in Item 408 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.Regulation S-K.
