Note 1 Basis of Presentation and Summary of Significant Accounting Policies

BankUnited, Inc. is a national bank holding company with one wholly-owned subsidiary, BankUnited, collectively, the Company. BankUnited, a national banking association headquartered in Miami Lakes, Florida, provides a full range of banking and related services to individual and corporate customers through 90 banking centers located in 15 Florida counties and 6 banking centers located in the New York metropolitan area at June 30, 2017 . The Bank also offers certain commercial lending and deposit products through national platforms.

In connection with the FSB Acquisition, BankUnited entered into two loss sharing agreements with the FDIC. The Loss Sharing Agreements consist of the Single Family Shared-Loss Agreement and the Commercial Shared-Loss Agreement. Assets covered by the Loss Sharing Agreements are referred to as covered assets or, in certain cases, covered loans. The Single Family Shared-Loss Agreement provides for FDIC loss sharing and the Bank’s reimbursement for recoveries to the FDIC through May 21, 2019 for single family residential loans and OREO. Loss sharing under the Commercial Shared-Loss Agreement terminated on May 21, 2014. The Commercial Shared-Loss Agreement continued to provide for the Bank’s reimbursement of recoveries to the FDIC through June 30, 2017 for all other covered assets, including commercial real estate, commercial and industrial and consumer loans, certain investment securities and commercial OREO. Pursuant to the terms of the Loss Sharing Agreements, the covered assets are subject to a stated loss threshold whereby the FDIC will reimburse BankUnited for 80% of losses related to the covered assets up to $4.0 billion and 95% of losses in excess of this amount, beginning with the first dollar of loss incurred.

The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X of the SEC. Accordingly, they do not include all of the information and footnotes required for a fair presentation of financial position, results of operations and cash flows in conformity with GAAP and should be read in conjunction with the Company’s consolidated financial statements and the notes thereto appearing in BKU’s Annual Report on Form 10-K for the year ended December 31, 2016 filed with the SEC. In the opinion of management, all adjustments, consisting of normal recurring adjustments, considered necessary for a fair presentation have been included. Operating results for the three and six months ended June 30, 2017 are not necessarily indicative of the results that may be expected in future periods.

Certain amounts presented for prior periods have been reclassified to conform to the current period presentation.

Accounting Estimates

In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, and expenses and disclosures of contingent assets and liabilities. Actual results could differ significantly from these estimates.

Significant estimates include the ALLL, the amount and timing of expected cash flows from covered assets and the FDIC indemnification asset, and the fair values of investment securities and other financial instruments. Management has used information provided by third party valuation specialists to assist in the determination of the fair values of investment securities.

New Accounting Pronouncements Adopted

ASU No. 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting . The amendments in this ASU simplified several aspects of the accounting for share-based payment transactions. The Company adopted this ASU in the first quarter of 2017. The amendment requiring the recognition of excess tax benefits and deficiencies as income tax benefit or expense in the income statement as opposed to being recognized as additional paid-in-capital was applied prospectively and resulted in the recognition of $0.3 million and $2.9 million in excess tax benefits in the consolidated statement of income line item " Provision for income taxes " for the three and six months ended June 30, 2017 , increasing net income by the same amount in each period. The adoption had no impact on basic and diluted earnings per share for the three months ended June 30, 2017 and increased basic and diluted earnings per share by $0.03 and $0.02 , respectively, for the six months ended June 30, 2017 . The Company retrospectively adopted the amendments requiring the classification of excess tax benefits and deficiencies with other income tax cash flows as operating activities and cash paid when directly withholding shares as financing activities in the accompanying consolidated statements of cash flows; the impact was not material. The Company has elected to continue its current practice of estimating the number of awards expected to vest in determining the amount of compensation cost to be recognized related to share based payment transactions.

June 30, 2017

ASU No. 2017-08, Receivables—Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities. The amendments in this ASU require certain premiums on callable debt securities to be amortized to the earliest call date. The amortization period for callable debt securities purchased as a discount will not be impacted. The Company early-adopted this ASU in the first quarter of 2017 with no material impact on the Company's consolidated financial position, results of operations or cash flows.

ASU No. 2016-06, Derivatives and Hedging (Topic 815): Contingent Put and Call Options in Debt Instruments. The amendments in this ASU clarify the requirements for assessing whether contingent call (put) options that can accelerate the payment of principal on debt instruments are clearly and closely related to their debt hosts. A company performing the assessment under these amendments is required to assess the embedded call (put) options solely in accordance with a four-step decision sequence, without also considering whether the contingency is related to interest rates or credit risks. The Company adopted this ASU in the first quarter of 2017 with no impact on its consolidated financial position, results of operations or cash flows.

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. Entities should apply the amendments in this ASU retrospectively to each prior reporting period presented incorporating certain practical expedients, or retrospectively with the cumulative effect of initially applying the ASU recognized at the date of initial application. 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 $6.5 million for the six months ended June 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 retrospectively.

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. The carrying value of equity

June 30, 2017

investments for which fair value changes will be recognized in earnings after adoption totaled $72 million and had unrealized gains of $10.9 million at June 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 lease 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.

In January 2017, the FASB issued 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 will recognize 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. This amendment is effective for annual or interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Entities should apply the amendment prospectively. Early adoption is permitted, including in an interim period, for impairment tests performed after January 1, 2017. The Company generally performs its goodwill impairment test in the third quarter of each fiscal year, and intends to early adopt this ASU for the impairment test performed in the third quarter of 2017. While it is not possible to determine the future relationship of the carrying amount of a reporting unit to its fair value, the Company currently has a single reporting unit and historically, the fair value of that reporting unit has substantially exceeded its carrying amount.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - UNAUDITED

June 30, 2017

The Company monitors its investment securities available for sale for OTTI on an individual security basis. No securities were determined to be other-than-temporarily impaired during the six months ended June 30, 2017 or 2016 . The Company does not intend to sell securities that are in significant unrealized loss positions at June 30, 2017 and it is not more likely than not that the Company will be required to sell these securities before recovery of the amortized cost basis, which may be at maturity. At June 30, 2017 , 79 securities were in unrealized loss positions. The amount of impairment related to 31 of these securities was considered insignificant, totaling approximately $268 thousand and no further analysis with respect to these securities was considered necessary. The basis for concluding that impairment of the remaining securities was not other-than-temporary is further described below:

U.S. Government agency and sponsored enterprise residential MBS and commercial MBS

At June 30, 2017 , six U.S. Government agency and sponsored enterprise residential MBS and four U.S. Government agency and sponsored enterprise commercial MBS were in unrealized loss positions. For eight 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 two 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. Given the expectation of timely payment of principal and interest, the impairments were considered to be temporary.

Private label residential MBS and CMOs

At June 30, 2017 , eight private label residential MBS and CMOs were in unrealized loss positions, primarily as a result of an increase in medium and long-term market interest rates subsequent to acquisition. The amount of impairment of each of the individual securities was less than 3% of amortized cost. These securities were assessed for OTTI using credit and prepayment behavioral models that incorporate CUSIP level constant default rates, voluntary prepayment rates and loss severity and delinquency assumptions. The results of these assessments were not indicative of credit losses related to any of these securities as of June 30, 2017 . Given the limited severity of impairment and the expectation of timely recovery of outstanding principal, the impairments were considered to be temporary.

Private label commercial MBS :

At June 30, 2017 , six private label commercial MBS were in unrealized loss positions. The amount of impairment of each of the individual securities was less than 3% of amortized cost. The unrealized losses were primarily attributable to increases in market interest rates since the purchase of the securities. These securities were assessed for OTTI using credit and prepayment behavioral models incorporating assumptions consistent with the collateral characteristics of each security. The results of this analysis were not indicative of expected credit losses. Given the limited severity of impairment and the expectation of timely recovery of outstanding principal, the impairments were considered to be temporary.

Single family rental real estate-backed securities:

At June 30, 2017 , two 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. The amount of impairment of each of the individual securities was less than 2% of amortized cost. Management's analysis of the credit characteristics, including loan-to-value and debt service coverage ratios, and levels of subordination for each of the securities is not indicative of projected credit losses. Given the limited severity of impairment and the absence of projected credit losses, the impairments were considered to be temporary.

Non-mortgage asset-backed securities:

At June 30, 2017 , three non-mortgage asset-backed securities were in unrealized loss positions, due primarily to increases in market interest rates subsequent to the date of acquisition. The amount of impairment of each of the individual securities was 3% or less of amortized cost. These securities were assessed for OTTI using credit and prepayment behavioral models incorporating assumptions consistent with the collateral characteristics of each security. The results of this analysis were not indicative of expected credit losses. Given the limited severity of impairment and the expectation of timely recovery of outstanding principal, the impairments were considered to be temporary.

State and municipal obligations:

At June 30, 2017 , 18 state and municipal obligations were in unrealized loss positions, primarily due to increases in market interest rates. The amount of impairment of each of the individual securities was 4% or less 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 specializing in the analysis and credit review of municipal securities. Given the absence of expected credit losses and management's ability and intent to hold the securities until recovery, the impairments were considered to be temporary.

SBA securities:

At June 30, 2017 , one SBA security was in an unrealized loss position. The amount of impairment was less than 2% of amortized cost. This security was purchased at a premium and the impairment was attributable primarily to increased prepayment speeds. The timely payment of principal and interest on this security is guaranteed by this U.S. Government agency. Given the limited severity of impairment and the expectation of timely payment of principal and interest, the impairment was considered to be temporary.

Credit quality information

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

ACI loans or pools are considered to be impaired when it is probable that the Company will be unable to collect all of the expected cash flows at acquisition (as adjusted for any additional cash flows expected to be collected arising from changes in estimates after acquisition), other than due to changes in interest rate indices and prepayment assumptions.

Non-covered loans contractually delinquent by 90 days or more and still accruing totaled $0.4 million and $1.6 million at June 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 $2.6 million for the three and six months ended June 30, 2017 , respectively, and $0.9 million and $1.5 million for the three and six months ended June 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 new 1-4 single family residential portfolio.

Internal risk ratings are considered the most meaningful indicator of credit quality for commercial loans. Internal risk ratings are a key factor in identifying loans that are individually evaluated for impairment and impact management’s estimates of loss factors used in determining the amount of the ALLL. Internal risk ratings are updated on a continuous basis. Generally, relationships with balances in excess of defined thresholds, ranging from $1 million to $3 million , are re-evaluated at least annually and more frequently if circumstances indicate that a change in risk rating may be warranted. Loans exhibiting potential credit weaknesses that deserve management’s close attention and that if left uncorrected may result in deterioration of the repayment capacity of the borrower are categorized as special mention. Loans with well-defined credit weaknesses, including payment defaults, declining collateral values, frequent overdrafts, operating losses, increasing balance sheet leverage, inadequate cash flow, project cost overruns, unreasonable construction delays, past due real estate taxes or exhausted interest reserves, are assigned an internal risk rating of substandard. A loan with a weakness so severe that collection in full is highly questionable or improbable, but because of certain reasonably specific pending factors has not been charged off, will be assigned an internal risk rating of doubtful.

Note 5 FDIC Indemnification Asset

When the Company recognizes gains or losses related to covered assets in its consolidated financial statements, changes in the estimated amount recoverable from the FDIC under the Loss Sharing Agreements with respect to those gains or losses are also reflected in the consolidated financial statements. Covered loans may be resolved through prepayment, short 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 loss on FDIC indemnification ” and reflected as corresponding increases or decreases in the FDIC indemnification asset.

In addition, recoveries of previously indemnified losses on assets that were previously covered under the Commercial Shared-Loss Agreement resulted in reimbursements due to the FDIC through June 30, 2017. These transactions are included in the tables below. Amounts payable to the FDIC resulting from these transactions are recognized in other liabilities in the accompanying consolidated balance sheets.

The following tables summarize the components of the gains and losses associated with covered assets, along with the related additions to or reductions in the amounts recoverable from the FDIC under the Loss Sharing Agreements, as reflected in the consolidated statements of income for the periods indicated (in thousands):

Changes in the FDIC indemnification asset and in the liability to the FDIC for recoveries related to assets previously covered under the Commercial Shared-Loss Agreement for the six months ended June 30, 2017 and the year ended December 31, 2016 , were as follows (in thousands):

Other liabilities	(50		)	(23		)
	$	406,770		$	515,910

Note 6 Income Taxes

The Company’s effective income tax rate was 30.4% and 33.0% for the three months ended June 30, 2017 and 2016 , respectively, and 30.6% and 33.9% for the six months ended June 30, 2017 and 2016 , respectively. The effective income tax rate differed from the statutory federal income tax rate of 35% in both periods due primarily to the effect of income not subject to tax, offset by state income taxes. In addition, the effective income tax rate for the three and six months ended June 30, 2017 reflected the impact of $0.3 million and $2.9 million , respectively, in excess tax benefits resulting from activity related to vesting of share-based awards and exercise of stock options.

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 $68 million and $71 million at June 30, 2017 and December 31, 2016 , respectively. Unfunded commitments for affordable housing investments, included in other liabilities in the accompanying consolidated balance sheet, were $37 million and $53 million at June 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 June 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 six months ended June 30, 2017 and 2016 .

Note 7 Derivatives and Hedging Activities

The Company uses interest rate swaps to manage interest rate risk related to liabilities that expose the Company to variability in cash flows due to changes in interest rates. The Company enters into LIBOR-based interest rate swaps that are designated as cash flow hedges with the objective of limiting the variability of interest payment cash flows resulting from changes in the benchmark interest rate LIBOR. The effective portion of changes in the fair value of interest rate swaps designated as cash flow hedging instruments is reported in AOCI and subsequently reclassified into interest expense in the same period in which the related interest on the floating-rate debt obligations affects earnings.

The Company also enters into interest rate derivative contracts with certain of its commercial borrowers to enable those borrowers to manage their exposure to interest rate fluctuations. To mitigate interest rate risk associated with these derivative contracts, the Company enters into offsetting derivative contract positions with primary dealers. These interest rate derivative contracts are not designated as hedging instruments; therefore, changes in the fair value of these derivatives are recognized immediately in earnings. The impact on earnings related to changes in fair value of these derivatives for the three and six months ended June 30, 2017 and 2016 was not material.

The Company may be exposed to credit risk in the event of non-performance by the counterparties to its interest rate derivative agreements. The Company assesses the credit risk of its financial institution counterparties by monitoring publicly available credit rating and financial information. The Company manages dealer credit risk by entering into interest rate derivatives only with primary and highly rated counterparties, the use of ISDA master agreements 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 borrower counterparties through its normal loan underwriting and credit monitoring policies and procedures. The Company does not currently anticipate any losses from failure of interest rate derivative counterparties to honor their obligations.

The CME amended its rules effective January 2017 to legally 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 June 30, 2017 .

During the three and six months ended June 30, 2017 and 2016 , the amount of loss reclassified from AOCI into interest expense (effective portion) was $2.6 million , $5.5 million , $4.3 million and $9.3 million , respectively.

During the six months ended June 30, 2017 and 2016 , no derivative positions designated as cash flow hedges were discontinued and none of the gains and losses reported in AOCI were reclassified into earnings as a result of the discontinuance of cash flow hedges or because of the early extinguishment of debt. As of June 30, 2017 , the amount of loss expected to be reclassified from AOCI into earnings during the next twelve months was $7.1 million .

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 contracts entered into with borrowers not subject to master netting agreements.

At June 30, 2017 , the Company had pledged investment securities available for sale with a carrying amount of $44 million and cash on deposit of $3 million as collateral for interest rate swaps in a liability position. No 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.

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 numb er 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 six months ended June 30, 2017 , 47,848 RSUs and 47,848 PSUs were granted. During the six months ended June 30, 2016 , 57,873 RSUs and 57,873 PSUs were granted. The total liability for the share units was $1.8 million at June 30, 2017 . The total unrecognized compensation cost of $5.7 million for these share units at June 30, 2017 will be recognized over a weighted average remaining period of 2.31 years .

The 591,999 unvested share awards granted during the six months ended June 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.

Incentive awards

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 share units was $0.8 million at June 30, 2017 . The total unrecognized compensation cost of $5.7 million for these share units at June 30, 2017 will be recognized over a weighted average remaining period of 3.50 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.

Option Awards

A summary of activity related to stock option awards for the six months ended June 30, 2017 follows:



	Number of Option Awards		Weighted Average Exercise Price
Option awards outstanding, December 31, 2016	3,602,076		$	26.74
Exercised	(2,304,108	)	26.70
Option awards outstanding and exercisable, June 30, 2017	1,297,968		$	26.81

Activity related to stock option awards for the six months ended June 30, 2016 was not significant. The intrinsic value of options exercised and the related tax benefit was $25.3 million and $3.8 million , respectively, during the six months ended June 30, 2017 .

Note 10 Fair Value Measurements

Assets and liabilities measured at fair value on a recurring basis

Following is a description of the methodologies used to estimate the fair values of assets and liabilities measured at fair value on a recurring basis and the level within the fair value hierarchy in which those measurements are typically classified.

Investment securities available for sale —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 these securities include risk adjusted discount rates, projected prepayment rates, projected default rates and projected loss severity.

The Company uses third-party pricing services in determining fair value measurements for investment securities. To obtain an understanding of the methodologies and assumptions used, management reviews written documentation provided by the pricing services, conducts interviews with valuation desk personnel and reviews model results and detailed assumptions used to value selected securities as considered necessary. Management has established a robust price challenge process that includes a review by the treasury front office of all prices provided on a monthly basis. Any price evidencing unexpected month over month fluctuations or deviations from expectations is challenged. If considered necessary to resolve any discrepancies, a price will be obtained from an additional independent valuation source. The Company does not typically adjust the prices provided, other than through this established challenge process. The results of price challenges are subject to review by executive management. The Company has also established a quarterly process whereby prices provided by its primary pricing service for a sample of securities are validated. Any price discrepancies are resolved based on careful consideration of the assumptions and inputs employed by each of the pricing sources.

Servicing rights —Commercial servicing rights are valued using a discounted cash flow methodology incorporating contractually specified servicing fees and market based assumptions about prepayments, discount rates, default rates and costs of servicing. Prepayment and default assumptions are based on historical industry data for loans with similar characteristics. Assumptions about costs of servicing are based on market convention. Discount rates are based on rates of return implied by observed trades of underlying loans in the secondary market. Fair value of residential MSRs is estimated using a discounted cash flow technique that incorporates market‑based assumptions including estimated prepayment speeds, contractual servicing fees, cost to service, discount rates, escrow account earnings, ancillary income, and estimated defaults. Due to the 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 swaps are determined using widely accepted discounted cash flow modeling techniques. These discounted cash flow models use projections of future cash payments and receipts that are discounted at mid-market rates. Observable inputs that may impact the valuation of these instruments include LIBOR swap rates and LIBOR forward yield curves. These fair value measurements are generally classified within level 2 of the fair value hierarchy.

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 six months ended June 30, 2017 and 2016 that were related to servicing rights held at June 30, 2017 and 2016 totaled approximately $0.7 million and $1.3 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 June 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 $109 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 June 30, 2017 were 18.1% , 11.8% and 1.5% for investment grade, non-investment grade and option-arm securities, respectively. There were $26 million of option-arm securities with a subordination level of zero at June 30, 2017 .

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 June 30, 2017 (dollars in thousands):



	Fair Value at		Valuation Technique	Unobservable Input	Range (Weighted Average)
	June 30, 2017		Valuation Technique	Unobservable Input	Range (Weighted Average)
Investment grade	$	46,814	Discounted cash flow	Voluntary prepayment rate	2.74% - 24.84% (15.40%)
				Probability of default	0.17% - 4.01% (1.44%)
				Loss severity	15.00% - 75.00% (34.64%)
				Discount rate	2.21% - 7.07% (3.63%)

Non-investment grade	$	34,531	Discounted cash flow	Voluntary prepayment rate	0.95% - 29.40% (15.47%)
				Probability of default	0.00% - 4.16% (1.66%)
				Loss severity	15.00% - 85.00% (31.31%)
				Discount rate	0.70% - 21.58% (5.84%)

Option-arm (non-investment grade)	$	27,445	Discounted cash flow	Voluntary prepayment rate	6.58% - 6.58% (6.58%)
				Probability of default	2.73% - 2.73% (2.73%)
				Loss severity	35.00% - 35.00% (35.00%)
				Discount rate	3.39% - 15.86% (5.31%)

The significant unobservable inputs impacting the fair value measurement of private label residential MBS and CMOs include voluntary prepayment rates, probability of default, loss severity given default and discount rates. Generally, increases in probability of default, loss severity or discount rates would result in a lower fair value measurement. Alternatively, decreases in probability of default, loss severity or discount rates would result in a higher fair value measurement. For securities with less favorable credit characteristics, decreases in voluntary prepayment speeds may be interpreted as a deterioration in the overall credit quality of the underlying collateral and as such, lead to lower fair value measurements. The fair value measurements of those securities with higher levels of subordination will be less sensitive to changes in these unobservable inputs other than discount rates, while securities with lower levels of subordination will show a higher degree of sensitivity to changes in these unobservable inputs other than discount rates. Generally, a change in the assumption used for probability of default is accompanied by a directionally similar change in the assumption used for loss severity given default and a directionally opposite change in the assumption used for voluntary prepayment rate.

The following table provides information about the valuation techniques and significant unobservable inputs used in the valuation of servicing rights as of June 30, 2017 (dollars in thousands):



	Fair Value at		Valuation Technique	Unobservable Input	Range (Weighted Average)
	June 30, 2017		Valuation Technique	Unobservable Input	Range (Weighted Average)
Residential MSRs	$	17,032	Discounted cash flow	Prepayment rate	7.33% - 30.19% (10.82%)
				Discount rate	9.50% - 9.58% (9.51%)

Commercial servicing rights	$	12,096	Discounted cash flow	Prepayment rate	0.15% - 9.79% (7.78%)
				Discount rate	7.42% - 13.13% (12.00%)

Increases in prepayment rates or discount rates would result in lower fair value measurements and decreases in prepayment rates or discount rates would result in higher fair value measurements. Although the prepayment rate and the discount rate are not directly interrelated, they generally move in opposite directions.

Assets and liabilities measured at fair value on a non-recurring basis

Following is a description of the methodologies used to estimate the fair values of assets and liabilities that may be measured at fair value on a non-recurring basis, and the level within the fair value hierarchy in which those measurements are typically classified.

Impaired loans, OREO and other repossessed assets —The carrying amount of collateral dependent impaired loans is typically based on the fair value of the underlying collateral, which may be real estate, taxi medallions, or other business assets, less estimated costs to sell. 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.

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

The following tables present the carrying value of assets for which non-recurring changes in fair value have been recorded for the periods indicated (in thousands):

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 11 Commitments and Contingencies

The Company issues off-balance sheet financial instruments to meet the financing needs of its customers. These financial instruments include commitments to fund loans, unfunded commitments under existing lines of credit, and commercial and standby letters of credit. These commitments expose the Company to varying degrees of credit and market risk which are essentially the same as those involved in extending loans to customers, and are subject to the same credit policies used in underwriting loans. Collateral may be obtained based on the Company’s credit evaluation of the counterparty. The Company’s maximum exposure to credit loss is represented by the contractual amount of these commitments. Unfunded commitments under lines of credit include $10.9 million available under non-cancellable commitments in effect at the date of the FSB Acquisition, which are covered under the Single Family Shared-Loss Agreement if prescribed conditions are met.

Commitments to fund loans

These are agreements to lend funds to customers as long as there is no violation of any condition established in the contract. Commitments to fund loans generally have fixed expiration dates or other termination clauses and may require payment of a fee. Many of these commitments are expected to expire without being funded and, therefore, the total commitment amounts do not necessarily represent future liquidity requirements.

Unfunded commitments under lines of credit

Unfunded commitments under lines of credit include commercial, commercial real estate, home equity and consumer lines of credit to existing customers. Some of these commitments may mature without being fully funded.

Commercial and standby letters of credit

Letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. These letters of credit are primarily issued to support trade transactions or guarantee arrangements. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers.

Total lending related commitments outstanding at June 30, 2017 were as follows (in thousands):



Commitments to fund loans	$	649,215
Commitments to purchase loans	441,726
Unfunded commitments under lines of credit	2,003,346
Commercial and standby letters of credit	88,100
	$	3,182,387

Legal Proceedings

The Company is involved as plaintiff or defendant in various legal actions arising in the normal course of business. In the opinion of management, based upon advice of legal counsel, the likelihood is remote that the impact of these proceedings, either individually or in the aggregate, would be material to the Company’s consolidated financial position, results of operations or cash flows.

Overview

Quarterly Highlights

In evaluating our financial performance, we consider the level of and trends in net interest income, the net interest margin, levels and composition of non-interest income and non-interest expense, performance ratios such as the return on average assets and return on average equity 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, and portfolio delinquency and charge-off trends. We consider growth in earning assets and deposits, trends in funding mix and cost of funds. We analyze these ratios and trends against our own historical performance, our budgeted performance and the financial condition and performance of comparable financial institutions.

Performance highlights include:

•

Net income for the quarter ended June 30, 2017 was $66.4 million , or $0.60 per diluted share, compared to $56.7 million , or $0.52 per diluted share for the quarter ended June 30, 2016 . Earnings for the second quarter of 2017 generated an annualized return on average stockholders' equity of 10.33% and a return on average assets of 0.94% .

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, 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. The mix of interest bearing liabilities is influenced by the Company's liquidity profile, management's assessment of the desire for lower cost funding sources weighed against relationships with customers and growth requirements and is impacted by 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 June 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.

Table of Contents

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% (dollars in thousands):

Three months ended June 30, 2017 compared to three months ended June 30, 2016

Net interest income, calculated on a tax-equivalent basis, was $249.9 million for the three months ended June 30, 2017 compared to $222.5 million for the three months ended June 30, 2016 , an increase of $27.4 million . The increase in net interest income was comprised of an increase in tax-equivalent interest income of $40.5 million , offset by an increase in interest expense of $13.1 million .

The increase in tax-equivalent interest income was comprised primarily of a $30.5 million increase in interest income from loans and an $9.8 million increase in interest income from investment securities.

Table of Contents

Increased interest income from loans was attributable to a $2.0 billion increase in the average balance outstanding and a 0.10% increase in the tax-equivalent yield to 5.24% for the three months ended June 30, 2017 from 5.14% for the three months ended June 30, 2016 .

The tax-equivalent yield on non-covered loans was 3.78% for the three months ended June 30, 2017 compared to 3.56% for the three months ended June 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 $76.6 million and $76.4 million for the three months ended June 30, 2017 and 2016 , respectively. The tax-equivalent yield on those loans increased to 54.51% for the three months ended June 30, 2017 from 40.97% for the three months ended June 30, 2016 . The increase in the yield on covered loans resulted primarily from improvements in expected cash flows for ACI loans.

The impact on the overall yield on loans of increased yields on both covered and non-covered loans considered individually was somewhat offset by the continued increase in non-covered loans, with yields lower than those on covered loans, as a percentage of total loans.

The average balance of investment securities increased by $850 million for the three months ended June 30, 2017 from the three months ended June 30, 2016 while the tax-equivalent yield increased to 3.05% from 2.82% . The most significant factors contributing to the increase in the tax-equivalent yield were (i) resetting of coupon rates on floating-rate securities and (ii) net purchases of securities at higher yields.

The components of the increase in interest expense for the three months ended June 30, 2017 as compared to the three months ended June 30, 2016 were a $10.7 million increase in interest expense on deposits and a $2.4 million increase in interest expense on FHLB advances.

The increase in interest expense on deposits was attributable to an increase of $2.2 billion in average interest bearing deposits and an increase in the average cost of interest bearing deposits of 0.15% to 0.93% for the three months ended June 30, 2017 from 0.78% for the three months ended June 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 0.19% to 1.21% for the three months ended June 30, 2017 from 1.02% for the three months ended June 30, 2016 . The increase in cost was driven by increased market rates and to a lesser extent, an extension of maturities through interest rate swaps.

The net interest margin, calculated on a tax-equivalent basis, for the three months ended June 30, 2017 was 3.76% as compared to 3.75% for the three months ended June 30, 2016 . The interest rate spread decreased to 3.58% for the three months ended June 30, 2017 from 3.60% for the three months ended June 30, 2016 . The relative consistency of net interest margin and interest rate spread resulted primarily from the offsetting factors discussed above. Future trends in the net interest margin will be impacted by changes in market interest rates, including changes in the shape of the yield curve, by the mix of interest earning assets, including the decline in covered loans as a percentage of total loans, and by the Company's ability to manage the cost of funds while growing deposits in competitive markets.

Six months ended June 30, 2017 compared to six months ended June 30, 2016

Net interest income, calculated on a tax-equivalent basis, was $490.7 million for the six months ended June 30, 2017 compared to $436.6 million for the six months ended June 30, 2016 , an increase of $54.0 million . The increase in net interest income was comprised of an increase in tax-equivalent interest income of $76.1 million , offset by an increase in interest expense of $22.1 million .

The increase in tax-equivalent interest income was comprised primarily of a $54.0 million increase in interest income from loans and a $21.1 million increase in interest income from investment securities.

Increased interest income from loans was attributable to a $2.3 billion increase in the average balance outstanding partially offset by a 0.05% decrease in the tax-equivalent yield to 5.15% for the six months ended June 30, 2017 from 5.20% for the six months ended June 30, 2016 . Offsetting factors contributing to the overall decline in the yield on loans included:

•

Although the yield on non-covered loans increased to 3.70% for the six months ended June 30, 2017 from 3.59% for the six months ended June 30, 2016, lower-yielding non-covered loans comprised a greater percentage of the portfolio for the six months ended June 30, 2017 than for the corresponding period in 2016 . Non-covered loans represented 97.0% of the average balance of loans outstanding for the six months ended June 30, 2017 compared to 95.5% for the six months ended June 30, 2016 .

Table of Contents


•	Interest income on covered loans totaled $151.7 million and $152.2 million for the six months ended June 30, 2017 and 2016 , respectively. The tax-equivalent yield on those loans increased to 52.10% for the six months ended June 30, 2017 from 39.54% for the six months ended June 30, 2016 .

The average balance of investment securities increased by $1.0 billion for the six months ended June 30, 2017 from the six months ended June 30, 2016 while the tax-equivalent yield increased to 3.03% from 2.80% .

The components of the increase in interest expense for the six months ended June 30, 2017 as compared to the six months ended June 30, 2016 were an $18.8 million increase in interest expense on deposits and a $3.3 million increase in interest expense on FHLB advances.

The increase in interest expense on deposits was attributable to an increase of $2.3 billion in average interest bearing deposits and an increase in the average cost of interest bearing deposits of 0.12% to 0.89% for the six months ended June 30, 2017 from 0.77% for the six months ended June 30, 2016 . The increase in interest expense on FHLB advances was a result of an increase of $0.4 billion in the average balance of advances, and to a lesser extent, an increase in the average rate paid.

Factors contributing to the changes in yields and costs for the six 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 six months ended June 30, 2017 was 3.73% as compared to 3.79% for the six months ended June 30, 2016 . The interest rate spread decreased to 3.55% for the six months ended June 30, 2017 from 3.64% for the six months ended June 30, 2016 . The declines in net interest margin and interest rate spread resulted primarily from the factors discussed above.

Provision for Loan Losses

The provision for loan losses is the amount of expense that, based on our judgment, is required to maintain the ALLL at an adequate level to absorb probable losses inherent in the loan portfolio at the balance sheet date and that, in management’s judgment, is appropriate under GAAP. The determination of the amount of the ALLL 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 Lease Losses” below for more information about how we determine the appropriate level of the allowance.

For the three months ended June 30, 2017 and 2016 , we recorded provisions for loan losses of $12.0 million and $14.3 million , respectively, related to non-covered loans. For the six months ended June 30, 2017 and 2016 , we recorded provisions for loan losses of $23.3 million and $18.7 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 reasons for the decrease in the provision for loan losses related to non-covered loans for the quarter ended June 30, 2017 compared to the quarter ended June 30, 2016 were (i) a net decrease in the relative impact on the provision of changes in quantitative and qualitative loss factors and (ii) lower loan growth, partially offset by (iii) an increase of $2.7 million in the provision related to taxi medallion loans.

Factors contributing to the increase in the provision for loan losses related to non-covered loans for the six months ended June 30, 2017 as compared to the six months ended June 30, 2016 were (i) the increase of $11.0 million in the provision related to taxi medallion loans and (ii) an increase in the provision related to impaired loans in other portfolio segments, partially offset by (iii) a net decrease in the relative impact on the provision of changes in quantitative and qualitative loss factors and (iv) the impact of lower loan growth in 2017.

For the three months ended June 30, 2017 and 2016 , we recorded provisions for loan losses of $1.7 million and $0.1 million , respectively, related to covered loans. For the six months ended June 30, 2017 and 2016, we recorded provisions for (recovery of) loan losses of $2.4 million and $(0.7) million , respectively, related to covered loans. The provision for the three and six months ended June 30, 2017 related primarily to impairment recognized on an ACI HELOC pool. As discussed below in the section entitled "Non-interest income," the impact on our results of operations of any provision for (recovery of) loan losses on covered loans is significantly mitigated by the corresponding impact on the FDIC indemnification asset, recorded in non-interest income.

Non-Interest Income

The Company reported non-interest income of $29.9 million and $28.9 million for the three months ended June 30, 2017 and 2016 , respectively. Non-interest income was $58.0 million and $52.1 million for the six months ended June 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):

Non-interest income related to transactions in the covered assets

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 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 six months ended June 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 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.

Table of Contents

The following table provides further detail of the components of income from resolution of covered assets, net, for the periods indicated (in thousands):



	Three Months Ended June 30,				Six Months Ended June 30,
	2017		2016		2017			2016
Payments in full	$	8,351	$	9,386	$	15,778		$	17,419

Income from resolution of covered assets, net	$	8,361	$	9,545	$	15,666		$	17,543

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 for covered residential loans) and the FDIC refuses to 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):



	Three Months Ended June 30,						Six Months Ended June 30,
	2017			2016			2017			2016
Loss on sale of covered loans	$	(3,447	)	$	(4,151	)	$	(1,565	)	$	(4,863	)

Net impact on pre-tax earnings	$	(688	)	$	(788	)	$	(308	)	$	(931	)

Pricing received on the sale of covered loans may vary based on (i) market conditions, including the interest rate environment, the amount of capital seeking investment and the secondary supply of loans with a particular performance history or collateral type, (ii) the type and quality of collateral, (iii) the performance history of loans included in the sale and (iv) whether or not the loans have been modified. We anticipate that we will continue to exercise our right to sell covered residential loans on a quarterly basis in the future.

Other components of non-interest income

Period over period increases in service charges and fees and income from lease financing corresponded to the growth in deposits, loans and the portfolio of equipment under operating lease.

Gains on sale of non-covered loans for the three and six months ended June 30, 2017 and 2016 related primarily to sales of loans by SBF.

Gains on investment securities available for sale for the three and six months ended June 30, 2017 and 2016 related to sales of securities in the normal course of managing liquidity, portfolio duration and yield.

Non-Interest Expense

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



	Three Months Ended June 30,				Six Months Ended June 30,
	2017		2016		2017		2016
Employee compensation and benefits	$	60,388	$	55,752	$	120,059	$	111,212
Occupancy and equipment	19,251		19,065		37,860		38,332
Amortization of FDIC indemnification asset	45,663		38,060		90,126		77,754
Deposit insurance expense	5,588		4,231		11,063		7,923
Professional fees	4,785		3,604		9,825		6,235
Telecommunications and data processing	3,745		3,721		7,029		7,054
Depreciation of equipment under operating lease	8,733		6,647		16,750		13,149
Other non-interest expense	12,282		13,032		24,280		24,561
	$	160,435	$	144,112	$	316,992	$	286,220

Annualized non-interest expense as a percentage of average assets was 2.3% for both the three and six months ended June 30, 2017 and 2016 . Excluding amortization of the FDIC indemnification asset, non-interest expense as a percentage of average assets was 1.6% for both the three and six months ended June 30, 2017 and 1.7% for both the three and six months ended June 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 six months ended June 30, 2017 increased by $4.6 million and $8.8 million compared to the corresponding periods in 2016 . The increases for the three and six months ended June 30, 2017 primarily reflected general increases in salaries, equity based compensation, bonus and incentive accruals and the cost of benefits.

Amortization of FDIC indemnification asset

Amortization of FDIC indemnification asset totaled $45.7 million and $90.1 million , respectively, for the three and six months ended June 30, 2017 compared to $38.1 million and $77.8 million , respectively, for the three and six months ended June 30, 2016 .

The FDIC indemnification asset was initially recorded at its estimated fair value, representing the present value of estimated future cash payments from the FDIC for probable losses on covered assets. As projected cash flows from the ACI loans have increased, the yield on the loans has increased accordingly and the estimated future cash payments from the FDIC have decreased. This change in estimated cash flows is recognized prospectively, consistent with the recognition of the increased cash flows from the ACI loans. As a result, the FDIC indemnification asset is being amortized to the amount of the estimated future cash flows. For the three and six months ended June 30, 2017 , the average rate at which the FDIC indemnification asset was amortized was 41.76% and 38.92% , respectively, compared to 23.08% and 22.65% , respectively, during the comparable periods in 2016 .

The rate of amortization will increase if estimated future cash payments from the FDIC decrease. The amount of amortization is impacted by both the change in the amortization rate and the decrease in the average balance of the indemnification asset. As we continue to submit claims under the Loss Sharing Agreements and recognize periodic amortization, the balance of the indemnification asset will continue to decline.

Table of Contents

See Note 5 to the consolidated financial statements for a rollforward of the FDIC indemnification asset for the six months ended June 30, 2017 and the year ended December 31, 2016 . The entire balance of the FDIC indemnification asset relates to residential loans and OREO covered under the Single Family Shared-Loss Agreement. The following table presents the carrying value of the FDIC indemnification asset and the estimated future cash flows at June 30, 2017 and December 31, 2016 (in thousands):



	June 30, 2017			December 31, 2016
FDIC indemnification asset	$	406,820		$	515,933
Less expected amortization	(208,094		)	(245,350		)
Amount expected to be collected from the FDIC	$	198,726		$	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 $1.4 million and $3.1 million , respectively, for the three and six months ended June 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.

Professional fees

Professional fees increased by $1.2 million and $3.6 million , respectively, for the three and six months ended June 30, 2017 compared to the corresponding periods in 2016 . The increases resulted primarily from consulting fees related to risk management matters and legal fees related to a variety of routine matters.

Depreciation of equipment under operating lease

Depreciation of equipment under operating lease increased by $2.1 million and $3.6 million , respectively, for the three and six months ended June 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.

Income Taxes

The Company’s effective income tax rate was 30.4% and 30.6% for the three and six months ended June 30, 2017 , respectively, compared to 33.0% and 33.9% for the three and six months ended June 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 six months ended June 30, 2017 reflected the impact of $0.3 million and $2.9 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 $3.3 billion to $26.4 billion for the six months ended June 30, 2017 from $23.1 billion for the six months ended June 30, 2016 . This increase was driven by a $2.3 billion increase in the average balance of outstanding loans and a $1.0 billion increase in the average balance of investment securities. The increase in average loans reflected growth of $2.5 billion in average non-covered loans outstanding, partially offset by a $187 million decrease in the average balance of covered loans. The decrease in average non-interest earning assets period over period primarily reflected a

decrease in the FDIC indemnification asset. Growth in interest earning assets, resolution of covered loans and declines in the amount of the FDIC indemnification asset are trends that are expected to continue.

Average interest bearing liabilities increased $2.7 billion to $22.0 billion for the six months ended June 30, 2017 from $19.3 billion for the six months ended June 30, 2016 , due to increases of $2.3 billion in average interest bearing deposits and $398 million in average FHLB advances. Average non-interest bearing deposits increased by $107 million . We expect growth in average deposits to continue, corresponding to anticipated growth in interest earning assets.

Average stockholders' equity increased by $251 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 has focused on insuring adequate liquidity, adding a suitable balance of high credit quality, diversifying 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. Investment grade municipal securities provide liquidity along with higher tax-equivalent yields at longer durations than the portfolio in general. We have also invested in highly rated structured products that, while somewhat less liquid, provide us with attractive yields. Relatively short effective portfolio duration helps mitigate interest rate risk arising from the currently low level of market interest rates. The weighted average expected life of the investment portfolio as of June 30, 2017 was 4.8 years and the effective duration was 1.7 years.

The available for sale investment securities portfolio was in a net unrealized gain position of $115.2 million at June 30, 2017 with aggregate fair value equal to 101.7% of amortized cost. Net unrealized gains included $127.5 million of gross unrealized gains and $12.3 million of gross unrealized losses. Investment securities available for sale in an unrealized loss position at June 30, 2017 had an aggregate fair value of $1.3 billion . At June 30, 2017 , 95.6% of investment securities available for sale were backed by the U.S. Government, U.S. Government agencies or sponsored enterprises or were rated AAA , AA or A, based on the most recent third-party ratings. Investment securities available for sale totaling $71 million were rated below investment grade or not rated at June 30, 2017 , all of which were acquired in the FSB Acquisition and substantially all of which were in unrealized gain positions at June 30, 2017 .

We evaluate the credit quality of individual securities in the portfolio quarterly to determine whether any of the investments in unrealized loss positions are other-than-temporarily impaired. 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 intent to hold the security until maturity or for a period of time sufficient for a recovery in value;


•	whether it is more likely than not that we will be required to sell the security prior to recovery of its amortized cost basis;


•	the length of time and extent to which fair value has been less than amortized cost;


•	adverse changes in expected cash flows;


•	collateral values and performance;


•	the payment structure of the security, including levels of subordination or over-collateralization;


•	changes in the economic or regulatory environment;


•	the general market condition of the geographic area or industry of the issuer;


•	the issuer’s financial condition, performance and business prospects; and


•	changes in credit ratings.

Table of Contents

No securities were determined to be other-than-temporarily impaired at June 30, 2017 and 2016 , or during the three and six months then ended.

We do not intend to sell securities in significant unrealized loss positions at June 30, 2017 . Based on an assessment of our liquidity position and internal and regulatory guidelines for permissible investments and concentrations, it is not more likely than not that we will be required to sell securities in significant unrealized loss positions prior to recovery of amortized cost basis. The severity of impairment of individual securities in the portfolio is generally not material. Unrealized losses in the portfolio at June 30, 2017 were primarily attributable to an increase in market interest rates subsequent to the date the securities were acquired.

The timely repayment of principal and interest on U.S. Treasury, U.S. Government agency and sponsored enterprise securities in unrealized loss positions is explicitly or implicitly guaranteed by the full faith and credit of 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 each of the single family rental real estate-backed securities in unrealized loss positions is not indicative of projected credit losses. Management's analysis of the state and municipal obligations in unrealized loss positions included reviewing the ratings of the securities and the results of credit surveillance performed by an independent third party. Given the expectation of timely repayment of principal and interest and the generally limited severity of impairment, the impairments were considered to be temporary.

For further discussion of our analysis of investment securities for OTTI, see Note 3 to the consolidated financial statements.

We use third-party pricing services to assist us in estimating the fair value of investment securities. We perform a variety of procedures to ensure that we have a thorough understanding of the methodologies and assumptions used by the pricing services including obtaining and reviewing written documentation of the methods and assumptions employed, conducting interviews with valuation desk personnel and reviewing model results and detailed assumptions used to value selected securities as considered necessary. Our classification of prices within the fair value hierarchy is based on an evaluation of the nature of the significant assumptions impacting the valuation of each type of security in the portfolio. We have established a robust price challenge process that includes a review by our treasury front office of all prices provided on a monthly basis. Any price evidencing unexpected month over month fluctuations or deviations from our expectations based on recent observed trading activity and other information available in the marketplace that would impact the value of the security is challenged. Responses to the price challenges, which generally include specific information about inputs and assumptions incorporated in the valuation and their sources, are reviewed in detail. If considered necessary to resolve any discrepancies, a price will be obtained from an additional independent valuation specialist. 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 stocks are classified within level 1 of the hierarchy. At June 30, 2017 and December 31, 2016 , 1.7% 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 June 30, 2017 included certain private label residential MBS and trust preferred securities. These securities were classified within level 3 of the hierarchy because proprietary assumptions related to voluntary prepayment rates, default probabilities, loss severities and discount rates were considered significant to the valuation. There

were no transfers of investment securities between levels of the fair value hierarchy during the six months ended June 30, 2017 and 2016 .

For additional discussion of the fair values of investment securities, see Note 10 to the consolidated financial statements.

Residential mortgages and other consumer loans

Residential mortgages and other consumer loans totaled $4.4 billion , or 21.6% of total loans, at June 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 June 30, 2017 , $122 million or 3.2% 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.

The following charts present the distribution of the non-covered 1-4 single family residential mortgage portfolio by interest rate terms and contractual lives at the dates indicated:


(1)	Fixed-rate loans with contractual terms of 20 years comprise less than 3% of the total at both June 30, 2017 and December 31, 2016 , and are reported with 15 year fixed above.

(1)	No other state represented borrowers with more than 4.0% of non-covered 1-4 single family residential loans outstanding at June 30, 2017 or December 31, 2016 .

Home equity loans and lines of credit are not significant to the non-covered loan portfolio.

Other consumer loans are comprised primarily of consumer installment financing, loans secured by certificates of deposit, unsecured personal lines of credit and demand deposit account overdrafts.

Commercial loans and leases

The commercial portfolio segment includes loans secured by multi-family properties, loans secured by both owner-occupied and non-owner occupied commercial real estate, a limited amount of construction and land loans, commercial and industrial loans and direct financing leases.

Management’s loan origination strategy is heavily focused on the commercial portfolio segment, which comprised 80.5% and 81.6% of non-covered loans as of June 30, 2017 and December 31, 2016 , respectively.

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

The following charts present the distribution of non-owner occupied commercial real estate by product types at the dates indicated:

Loans secured by commercial real estate typically have shorter repayment periods and re-price more frequently than 1-4 single family residential loans but may have longer terms and re-price less frequently than commercial and industrial loans. The Company’s underwriting standards generally provide for loan terms of five to ten years, with amortization schedules of no more than thirty years. LTV ratios are typically limited to no more than 80%. Owner-occupied commercial real estate loans typically have risk profiles more closely aligned with that of commercial and industrial loans than with other types of commercial real estate loans. Construction and land loans represented only 1.2% of the total loan portfolio at June 30, 2017 . Construction and land loans are generally made for projects expected to stabilize within eighteen months of completion in sub-markets with strong fundamentals and, to a lesser extent, for-sale residential projects to experienced developers with a strong cushion between market prices and loan basis.

Table of Contents

Commercial and industrial loans are typically made to small and middle market businesses and include equipment loans, secured and unsecured working capital facilities, formula-based loans, mortgage warehouse lines, taxi medallion loans, SBA product offerings and business acquisition finance credit facilities. These loans may be structured as term loans, typically with maturities of three to seven years, or revolving lines of credit which may have multi-year maturities. Commercial loans include shared national credits totaling $1.4 billion at June 30, 2017 , typically relationship based loans to borrowers in our geographic footprint.

Through its commercial lending subsidiaries, Pinnacle and Bridge, the Bank provides equipment and franchise financing on a national basis using both loan and lease structures. Pinnacle provides financing to state and local governmental entities directly and through vendor programs and alliances. Pinnacle offers a full array of financing structures including equipment lease purchase agreements and direct (private placement) bond re-fundings and loan agreements. Bridge has two operating divisions. The franchise finance division offers franchise acquisition, expansion and equipment financing, typically to experienced operators in well established concepts. The equipment finance division provides primarily transportation equipment financing through a variety of loan and lease structures. The Bank's SBF unit primarily originates SBA guaranteed commercial and commercial real estate loans, generally selling the guaranteed portion in the secondary market and retaining the unguaranteed portion in portfolio. The Bank engages in mortgage warehouse lending on a national basis.

Equipment under Operating Lease

Equipment under operating lease increased by $33 million to $573 million at June 30, 2017 , from $540 million at December 31, 2016 . The portfolio consisted primarily of 5,425 railcars, including hoppers, tank cars, boxcars, auto carriers, center beams and gondolas leased to North American commercial end-users. The portfolio also included non-commercial aircraft and other land transport equipment. The largest concentrations of rail cars were 2,265 hopper cars and 1,683 tank cars, primarily used to ship sand and petroleum products, respectively, for the energy industry. Equipment with a carrying value of $291 million at June 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 June 30, 2017 , residential loans covered under the Single Family Shared-Loss Agreement totaled $527 million .

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 and workout and recovery departments. Generally, commercial relationships with balances in excess of defined thresholds are re-evaluated at least annually and more frequently if circumstances indicate that a change in risk rating may be warranted. The defined thresholds range from $1 million to $3 million . Additionally, commercial loans are regularly reviewed by our internal credit review department. The Company utilizes a 13 grade internal asset risk classification system as part of its efforts to monitor and maintain commercial asset quality. Loans exhibiting potential credit weaknesses that deserve management’s close attention and that if left uncorrected may result in deterioration of the repayment capacity of the borrower are categorized as special mention. These borrowers may exhibit negative financial trends or erratic financial performance, strained liquidity, marginal collateral coverage, declining industry trends or weak management. Loans with well-defined credit weaknesses that may result in a loss if the deficiencies are not corrected are assigned a risk rating of substandard. These borrowers may exhibit payment defaults, inadequate cash flows, operating losses, increasing balance sheet leverage, project cost overruns, unreasonable construction delays, exhausted interest reserves, declining collateral values, frequent overdrafts or past due real estate taxes. Loans with weaknesses so severe that collection in full is highly questionable or improbable, but because of certain reasonably specific pending factors have not been charged off, are assigned an internal risk rating of doubtful.

Residential mortgage loans and consumer loans are not individually risk rated. Delinquency status is the primary measure we use to monitor the credit quality of these loans. We also consider original LTV and FICO score to be significant indicators of credit quality for the new 1-4 single family residential portfolio.

Non-covered Loans and Leases

Commercial Loans

The ongoing asset quality of significant commercial loans is monitored on an individual basis through our regular credit review and risk rating process. We believe internal risk rating is the best indicator of the credit quality of commercial loans. Homogenous groups of smaller balance commercial loans may be monitored collectively.

At June 30, 2017 , commercial loans with aggregate balances of $102 million , $364 million and $7 million were rated special mention, substandard and doubtful, respectively. At December 31, 2016 , commercial loans aggregating $72 million , $305 million and $12 million were rated special mention, substandard and doubtful, respectively. The balance of substandard loans at June 30, 2017 and December 31, 2016 included $143 million and $138 million , respectively, of taxi medallion finance loans. Criticized and classified loans represented 3.0% of the commercial loan portfolio, of which 0.9% were taxi medallion loans, at June 30, 2017 . See Note 4 to the consolidated financial statements for more detailed information about risk rating of commercial loans.

The commercial and industrial loan portfolio includes exposure to taxi medallion finance of $160 million at June 30, 2017 . The estimated value of underlying taxi medallion collateral and liquidity in the market for sales of medallions, a potential secondary source of repayment, have declined in recent periods due to competitive developments in the transportation-for-hire industry. We update our analysis of the cash flow generating capacity of the operation of 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. Actual debt service coverage of our medallion loans may in some cases be more favorable than these pro-forma cash flow capacity estimates. We also consider, if less favorable than our analysis of cash flow generating capacity, available borrower specific financial information. We update our analysis of estimated medallion valuations on a quarterly basis, based on these cash flow capacity estimates. See Note 10 to the consolidated financial statements for additional information about the valuation of New York City taxi medallions.

Table of Contents

The taxi medallion portfolio had the following characteristics at June 30, 2017 :


•	Approximately 98% of the portfolio secured directly by taxi medallions was concentrated in New York City.

•

Loans delinquent by 30 days or more totaled $13.9 million or 8.7% 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 $11.3 million or 7.1% of the portfolio, compared to $29.2 million or 16.4% of the portfolio at December 31, 2016 . Loans on non-accrual status totaled $66.2 million at June 30, 2017 , compared to $60.7 million 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.


•	At June 30, 2017 , $16.4 million , $143.1 million and $0.5 million of loans were rated pass, substandard and doubtful, respectively.

•

Based on our updated analysis of medallion values, the weighted average estimated current LTV for loans directly secured by medallions was approximately 94% and approximately 52% of those loans had current LTV in excess of 100%. At June 30, 2017 , our estimate of the value of New York City taxi medallions based on our cash flow model was $480,000 for both corporate and individual medallions. We have further discounted this value to $432,000 for purposes of determining the ALLL and the value of repossessed medallions in recognition of estimated selling costs and declining trends in medallion values.

•

In conjunction with our quarterly update of medallion values, using our analysis of the estimated cash flow generating capacity of a typical taxi medallion, we perform a pro-forma debt service coverage analysis. This analysis utilizes pro-forma revenues calculated based on data obtained from the Taxi and Limousine Commission and management's estimate of typical driver or fleet owner expenses, based primarily on available external data. The analysis also assumes an interest rate of the higher of the actual rate or 3.5% and an amortization period of the lesser of actual or 25 years. The characteristics of individual loans within our portfolio may differ from these pro-forma assumptions. Based on this analysis, approximately 88.1% of loans secured directly by taxi medallions had estimated pro-forma debt service coverage ratios of less than 1.00. The majority of these loans were current with respect to payment of principal and interest at June 30, 2017 .


•	The portfolio included 158 loans modified in TDRs with a recorded investment of $116.1 million .


•	In the aggregate, the ALLL related to taxi medallion loans was 9.8% of the outstanding balance at June 30, 2017 , compared to 6.0% at December 31, 2016 . Charge-offs of $11.8 million were recognized in the six months ended June 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, shortening amortization periods when possible with an emphasis on converting interest only loans, continuing to monitor industry data and obtain updated borrower and guarantor financial information, and identifying and closely monitoring loans with higher risk profiles. 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.

Equipment Under Operating Lease

Four operating lease relationships with assets under lease with a carrying value totaling $62 million were internally risk rated special mention or substandard at June 30, 2017 . The present value of remaining lease payments on these leases totaled approximately $17 million at June 30, 2017 . There have been no missed payments or time off-lease related to the operating lease portfolio to date. One relationship has been restructured to date, with no decrease in total minimum lease payments.

The primary risks inherent in the equipment leasing business are asset risk resulting from ownership of the equipment on operating lease and credit risk. Asset risk arises from fluctuations in supply and demand for the underlying leased equipment. Railcars are long-lived equipment with useful lives of approximately 35-50 years. The equipment is leased to commercial end-users with original lease terms generally ranging from 3-9 years at June 30, 2017 . We are exposed to the risk that, at the end of the lease term, the value of the asset will be lower than expected, potentially resulting in reduced future lease income over the remaining life of the asset or a lower sale value. Asset risk may also lead to changes in depreciation as a result of changes in the residual values of the operating lease assets or through impairment of asset carrying values.

Asset risk is evaluated and managed by a dedicated internal staff of asset managers, managed by seasoned equipment finance professionals with a broad depth and breadth of experience in the leasing business. Additionally, we have partnered with an industry leading, experienced service provider who provides fleet management and servicing, including lease

Table of Contents

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.

Residential and Other Consumer Loans

Non-covered 1-4 single family residential loans past due more than 30 days totaled $6.6 million and $12.7 million at June 30, 2017 and December 31, 2016 , respectively. The amount of these loans 90 days or more past due was $2.0 million and $2.1 million at June 30, 2017 and December 31, 2016 , respectively.

The majority of our non-covered residential mortgage portfolio consists of loans purchased through established correspondent channels. In general, we purchase performing jumbo mortgage loans which have FICO scores above 700, primarily are owner-occupied and full documentation, and have a current LTV of 80% or less. We perform due diligence on the purchased loans for credit, compliance, counterparty, payment history and property valuation.

The following tables show the distribution of non-covered 1-4 single family residential loans by original FICO and LTV as of the dates indicated:

Table of Contents

At June 30, 2017 , the non-covered 1-4 single family residential loan portfolio had the following characteristics: substantially all were full documentation with a weighted-average FICO score of 765 and a weighted-average LTV of 66.1% . The majority of this portfolio was owner-occupied, with 87.8% primary residence, 8.5% second homes and 3.7% investment properties. In terms of vintage, 24.3% of the portfolio was originated pre-2014, 14.4% in 2014, 24.1% in 2015 , 26.0% in 2016 and 11.2% in 2017 .

Other Consumer Loans

At June 30, 2017 and December 31, 2016 , there were no delinquent consumer loans.

Covered Loans

At June 30, 2017 , residential ACI loans totaled $461 million and residential non-ACI loans totaled $67 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 June 30, 2017 , accretable yield on residential ACI loans totaled $562 million and non-accretable difference related to those loans totaled $256 million .

At June 30, 2017 , the recorded investment in non-ACI 1-4 single family residential loans was $26.8 million ; $1.1 million or 4.0% of these loans were 30 days or more past due and $0.9 million or 3.4% of these loans were 90 days or more past due. At June 30, 2017 , the recorded investment in ACI 1-4 single family residential loans totaled $456.1 million ; $28.1 million or 6.2% of these loans were delinquent by 30 days or more and $15.8 million or 3.5% were delinquent by 90 days or more.

At June 30, 2017 , non-ACI home equity loans and lines of credit had an aggregate recorded investment of $39.7 million ; $4.0 million or 10.0% of these loans were 30 days or more past due and $2.7 million or 6.9% were 90 days or more past due. ACI home equity loans and lines of credit had a carrying amount of $4.7 million at June 30, 2017 ; 14.2% 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 June 30, 2017 is summarized as follows:



	ACI		Non-ACI
Loans resetting from interest only:
Previously reset	68.9	%	51.0	%
Scheduled to reset within 12 months	5.2	%	7.2	%
Scheduled to reset after 12 months	25.9	%	41.8	%
	100.0	%	100.0	%
Lien position:
First liens	11.4	%	18.3	%
Second or third liens	88.6	%	81.7	%
	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 ACI loans, and (iii) OREO and repossessed assets. Impaired loans also typically include loans modified in TDRs that are accruing and ACI loans for which expected cash flows at acquisition (as adjusted for any additional cash flows expected to be collected arising from changes in estimates after acquisition) have been revised downward since acquisition, other than due to changes in interest rate indices and prepayment assumptions.

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

Contractually delinquent ACI loans with remaining accretable yield are not reflected as non-accrual loans and are not considered to be non-performing assets because accretion continues to be recorded in income. Accretion continues to be recorded as long as there is an expectation of future cash flows in excess of carrying amount from these loans. The carrying value of ACI loans contractually delinquent by more than 90 days but on which income was still being recognized was $16 million at both June 30, 2017 and December 31, 2016 .

New 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 consumer loans are generally placed on non-accrual status when 90 days of interest is due and unpaid. When a loan is placed on non-accrual status, uncollected interest accrued is reversed and charged to interest income. Commercial loans are returned to accrual status only after all past due principal and interest has been collected and full repayment of remaining contractual principal and interest is reasonably assured. Residential loans are generally returned to accrual status when less than 90 days of interest is due and unpaid. Past due 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.

The following table summarizes loans modified in TDRs at June 30, 2017 (dollars in thousands):



	Number of TDRs	Recorded Investment		Related Specific Allowance
Residential and other consumer:

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 $238 million , of which $77 million were taxi medallion loans, at June 30, 2017 . Substantially all of these loans were current as to principal and interest at June 30, 2017 .

Loss Mitigation Strategies

Criticized or classified commercial loans in excess of certain thresholds are reviewed quarterly by the Criticized Asset Committee, which determines the appropriate strategy for collection to mitigate the amount of credit losses. Criticized asset reports for each relationship are presented by the assigned relationship manager and credit officer to the Criticized Asset Committee until such time as the relationships are returned to a satisfactory credit risk rating or otherwise resolved. The Criticized Asset Committee may require the transfer of a loan to our workout and recovery department, which is tasked to effectively manage the loan with the goal of minimizing losses and expenses associated with restructure, collection and/or liquidation of collateral. Commercial loans with a risk rating of substandard; impaired loans on non-accrual status; loans modified as TDRs; taxi medallion loans; or assets classified as OREO or repossessed assets are usually transferred to workout and recovery. Oversight of the workout and recovery department is provided by the Asset Recovery Committee.

We evaluate each residential loan in default to determine the most effective loss mitigation strategy, which may be modification, short sale, or foreclosure. Through 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 addition to the modification programs discussed above, we offer a proprietary Subordinate Lien Modification Program for home equity loans and lines of credit. This provides BankUnited the ability to offer a modification on loans covered under the Single Family Shared-Loss Agreement that are subordinate to either a BankUnited first lien or a first lien from another lender.

Analysis of the Allowance for Loan and Lease 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 loans is significantly mitigated by an increase in the FDIC indemnification asset. The determination of the amount of the ALLL is, by nature, highly complex and subjective. Future events that are inherently uncertain could result in material changes to the level of the ALLL. General economic conditions including but not limited to unemployment rates, the level of business investment and growth, real estate values, vacancy rates and rental rates in our primary market areas, the level of interest rates, and a variety of other factors that affect the ability of borrowers’ businesses to generate cash flows sufficient to service their debts will impact the future performance of the portfolio.

New and non- ACI Loans

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 as a basis for calculating the ALLL applicable to new loans. The new loan portfolio has not yet developed an observable loss trend. Therefore, the ALLL for new residential loans is based primarily on relevant proxy historical loss rates. The ALLL for new 1-4 single family residential loans is estimated using average annual loss rates on prime residential mortgage securitizations issued between 2003 and 2008 as a proxy. Based on the comparability of FICO scores and LTV ratios between loans included in those securitizations and loans in the Bank’s portfolio and the geographic diversity in the new purchased residential portfolio, we determined that prime residential mortgage securitizations provide an appropriate proxy for incurred losses in this portfolio class. A peer group 16-quarter average net charge-off 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 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 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

Table of Contents

determined by using default frequency and severity information applied at the loan level. Estimated default frequencies and severities are based on available industry data. In addition, we apply a floor to these calculated loss factors, based on the loss factor applied to the special mention portfolio.

Since the majority of the new commercial loan portfolio is not yet seasoned enough to exhibit a loss trend, the quantitative loss factors for a majority of pass rated new commercial loans is based on peer group average annual historical net charge-off rates by loan class and the Company’s internal credit risk rating system. Beginning in the first quarter of 2017, we revised the source of quantitative loss factors for certain loans, as follows:


•	Given the emergence of observable loss trends, the quantitative loss factors for the taxi medallion and Bridge portfolios are based on the Company’s average historical net charge-off rates.


•	The general quantitative loss factor for municipal finance receivables is based on the portfolio's external ratings and Moody's historical transition matrix, as opposed to the historical cumulative default curve for municipal obligations that was used previously.


•	For loans that are partially guaranteed by the SBA, the loss factor applied to the non-guaranteed portion of these loans is based on the 16-quarter average charge-off rate published by the SBA for each program


•	Mortgage warehouse loans have been segregated for the purpose of determining a quantitative loss factor, to better recognize the risk profile of this portfolio segment.

The net impact of these changes on the ALLL was not material.

The peer group used to calculate the average annual historical net charge-off rates that form the basis for our general reserve calculations for the majority of new commercial, home equity and consumer loans is made up of the banks included in the OCC Midsize Bank Group plus two additional banks in the New York region that management believes to be comparable based on size and nature of lending operations. The OCC Midsize Bank Group primarily includes commercial banks with total assets ranging from $10 - $50 billion and included 28 banks at June 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. We use a four-quarter loss experience period for the taxi medallion portfolio to recognize the recent deterioration in that portfolio. We use a 13-quarter loss experience period for the Bridge portfolios, reflective of the period over which an observable loss trend began to emerge.

With the exception of the Pinnacle municipal finance portfolio, a four quarter loss emergence period is used in the calculation of general reserves. A twelve quarter loss emergence period is used in the calculation of general reserves for the Pinnacle portfolio.

Qualitative Factors

Qualitative adjustments are made to the ALLL when, based on management’s judgment, there are internal or external factors impacting probable incurred losses not taken into account by the quantitative calculations. Potential qualitative adjustments are categorized as follows:


•	Portfolio performance trends, including trends in and the levels of delinquencies, non-performing loans and classified loans;


•	Changes in the nature of the portfolio and terms of the loans, specifically including the volume and nature of policy and procedural exceptions;


•	Portfolio growth trends;


•	Changes in lending policies and procedures, including credit and underwriting guidelines;


•	Economic factors, including unemployment rates and GDP growth rates;

Table of Contents


•	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.

ACI Loans

For ACI loans, a valuation allowance is established when periodic evaluations of expected cash flows reflect a deterioration resulting from credit related factors from the level of cash flows that were estimated to be collected at acquisition plus any additional expected cash flows arising from revisions in those estimates. We perform a quarterly analysis of expected cash flows for ACI loans.

Expected cash flows are estimated on a pool basis for ACI 1-4 single family residential and home equity loans. The analysis of expected pool cash flows incorporates updated pool level expected prepayment rate, default rate, delinquency level and loss severity given default assumptions. Prepayment, delinquency and default curves are derived primarily from roll rates generated from the historical performance of the portfolio over the immediately preceding four quarters. Loss severity given default assumptions are generated from the historical performance of the portfolio over the immediately preceding four quarters, while loss severity from loan sales is generated from historical performance over the immediately preceding twelve quarters. Estimates of default probability and loss severity given default also incorporate updated LTV ratios, at the loan level, based on Case-Shiller Home Price Indices for the relevant MSA. Costs and fees represent an additional component of loss on default and are projected based on historical experience over the last three years. The ACI home equity roll rates include the impact of delinquent, related senior liens and loans to borrowers who have not reaffirmed their debt discharged in Chapter 7 bankruptcy.

Our most recent 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 six months ended June 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 June 30, 2017 . No ALLL related to 1-4 single family residential and home equity ACI pools was recorded at December 31, 2016 .

The primary assumptions underlying estimates of expected cash flows for ACI commercial loans are default probability and severity of loss given default. Assessments of default probability and severity are based on net realizable value analyses prepared at the individual loan level. Based on our analysis, no ALLL related to ACI commercial loans was recorded at June 30, 2017 or December 31, 2016 .

The balance of the ALLL for non-covered loans at June 30, 2017 increased slightly as compared to December 31, 2016 . Decreases in quantitative loss factors applied to the majority of the commercial loan portfolio and decreases in qualitative factors applied to specific portfolios were offset by the impact of the growth of the loan portfolio and an increase in reserves for

Table of Contents

impaired taxi medallion loans. Factors influencing the change in the ALLL related to specific loan types at June 30, 2017 as compared to December 31, 2016 , include:


•	A decline of $0.4 million for non-covered 1-4 single family residential loans in spite of growth in the corresponding portfolio was primarily attributable to a decline in both the applicable quantitative historical loss rate and qualitative reserves.


•	A decrease of $2.4 million for multi-family loans primarily reflects decreases in quantitative loss factors, the decline in the corresponding portfolio and a decrease in the qualitative loss factor related to portfolio growth trends, offset in part by an increase in criticized and classified loans.


•	An increase of $3.0 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.


•	An increase of $4.4 million for owner occupied commercial real estate loans reflects increases in specific reserves for impaired loans and to a lesser extent, increases in quantitative and qualitative loss factors and the growth of the corresponding portfolio.


•	An increase of $5.0 million for taxi medallion loans was primarily driven by increases in reserves for classified and impaired loans due to a reduction in estimated collateral values, partially offset by charge-offs.


•	A decrease of $4.0 million for other commercial and industrial loans was primarily driven by a decrease in reserves for impaired and other classified loans, reflecting net charge-offs of $10.7 million , offset by growth in the corresponding portfolio.


•	A $5.4 million decrease for commercial lending subsidiaries primarily reflects decreases in quantitative loss factors for the municipal finance receivables and decreases in qualitative loss factors related to portfolio growth trends and credit concentrations.

FHLB Advances, Notes and Other Borrowings

In addition to deposits, we utilize FHLB advances to fund growth in interest earning assets; the advances provide us with additional flexibility in managing both term and cost of funding. FHLB advances are secured by FHLB stock, qualifying residential first mortgage, commercial real estate and home equity loans, and MBS. At June 30, 2017 and December 31, 2016 , outstanding FHLB advances totaled $5.0 billion and $5.2 billion , respectively.

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 June 30, 2017 and December 31, 2016 , BankUnited and the Company had capital levels that exceeded both the regulatory well-capitalized guidelines and all internal capital ratio targets.

Stockholders' equity increased to $2.6 billion at June 30, 2017 , an increase of $162 million , or 6.7% , 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 the 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 65.3% and 64.3% for the three and six months ended June 30, 2017 , respectively, compared to 60.3% and 59.7% for the three and six months ended June 30, 2016 , respectively. We retain a high percentage of our earnings to support our planned growth.

We filed a shelf registration statement 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 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 June 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 six months ended June 30, 2017 and 2016 , net cash provided by operating activities was $128.9 million and $144.0 million , respectively. Accretion on ACI loans, which is reflected as a non-cash reduction in net income to arrive at operating cash flows, totaled $153.2 million , and $153.4 million for the six months ended June 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 $272.4 million and $294.4 million for the six months ended June 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 June 30, 2017 , unencumbered investment securities available for sale totaled $4.6 billion . At June 30, 2017 , BankUnited had available borrowing capacity at the FHLB of $3.4 billion , unused borrowing capacity at the FRB of $413 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 June 30, 2017 , BankUnited’s 30 day total liquidity ratio was 188% . 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 June 30, 2017 , BankUnited’s one year liquidity ratio was 153% . 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 June 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

The principal component of the Company’s risk of loss arising from adverse changes in the fair value of financial instruments, or market risk, is interest rate risk, including the risk that assets and liabilities with similar re-pricing characteristics may not reprice at the same time or to the same degree. A primary objective of the Company’s asset/liability management activities is to maximize net interest income, while maintaining acceptable levels of interest rate risk. The ALCO is responsible for establishing policies to limit exposure to interest rate risk, and to ensure procedures are established to monitor compliance with these policies. The guidelines established by the ALCO are approved at least annually by the Board of Directors.

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

Table of Contents

permits management to assess the probable effects on the balance sheet not only of changes in interest rates, but also of proposed strategies for responding to them.

The income simulation model analyzes interest rate sensitivity by projecting net interest income over twelve and twenty-four month periods in a most likely rate scenario based on consensus forward interest rate curves versus net interest income in alternative rate scenarios. Simulations are generated based on both static and dynamic balance sheet assumptions. Management continually reviews and refines its interest rate risk management process in response to changes in the interest rate environment and economic climate. Currently, our model projects a down 100, plus 100, plus 200 and plus 300 basis point change with rates increasing by the magnitude of the rate ramp evenly over the next 12 months as well as flattening yield curve scenarios and instantaneous rate shocks of down 100, plus 100, plus 200 and plus 300 basis points. 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 and the impact on forecasted net interest income of down 100, plus 100, plus 200 and plus 300 basis point rate shock scenarios at June 30, 2017 and December 31, 2016 :



	Down 100		Plus 100		Plus 200		Plus 300
Policy Limits:
In year 1	(6.0	)%	(6.0	)%	(10.0	)%	(14.0	)%
In year 2	(9.0	)%	(9.0	)%	(13.0	)%	(17.0	)%
Model Results at June 30, 2017 - increase (decrease):
In year 1	(1.1	)%	0.9	%	1.6	%	1.9	%
In year 2	(4.3	)%	3.3	%	6.7	%	9.6	%
Model Results at December 31, 2016 - increase (decrease):
In year 1	(2.0	)%	1.5	%	2.8	%	3.4	%
In year 2	(3.7	)%	2.6	%	4.6	%	6.6	%

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 100 basis points at June 30, 2017 due to the current low rate environment. The parameters established by the ALCO stipulate that the modeled decline in EVE is considered acceptable if the decline is less than 9%, 18% and 27% in plus or minus 100, plus or minus 200 and plus or minus 300 basis point scenarios, respectively. As of June 30, 2017 , our simulation for the Company indicated percentage changes from base EVE of 1.4% , (3.4)% , (7.5)% and (12.1)% in down 100, plus 100, plus 200 and plus 300 basis point scenarios, respectively.

These measures fall within an acceptable level of interest rate risk per the policies established by the ALCO and the Board of Directors. In the event the models indicate an unacceptable level of risk, the Company could undertake a number of actions that would reduce this risk, including the sale or re-positioning of a portion of its available for sale investment portfolio, restructuring of borrowings, or the use of derivatives such as interest rate swaps and caps.

Many assumptions were used by the Company to calculate the impact of changes in interest rates, including the change in rates. Actual results may not be similar to the Company’s projections due to several factors including the timing and frequency of rate changes, market conditions, changes in depositor behavior and the shape of the yield curve. Actual results may also differ due to the Company’s actions, if any, in response to changing rates and conditions.

Derivative Financial Instruments

Interest rate swaps are one of the tools we use to manage interest rate risk. These derivative instruments are used to mitigate exposure to changes in interest rates on variable rate borrowings such as FHLB advances and to manage duration of liabilities. These interest rate swaps are designated as cash flow hedging instruments. The fair value of these instruments is included in other assets and other liabilities in our consolidated balance sheets and changes in fair value are reported in accumulated other comprehensive income. At June 30, 2017 , outstanding interest rate swaps designated as cash flow hedges had an aggregate notional amount of $2.2 billion . The aggregate fair value of interest rate swaps designated as cash flow hedges included in other liabilities was $0.5 million and the aggregate fair value of interest rate swaps designated as cash flow hedges included in other assets was $1.1 million .

Interest rate swaps and caps not designated as cash flow hedges had an aggregate notional amount of $2.2 billion at June 30, 2017 . The aggregate fair value of these interest rate swaps and caps included in other assets was $27.8 million and the aggregate fair value included in other liabilities was $28.1 million . These interest rate swaps and caps were entered into as accommodations to certain of our commercial borrowers.

See Note 7 to the consolidated financial statements for additional information about derivative financial instruments.

Off-Balance Sheet Arrangements

For more information on contractual obligations and commitments, see Note 11 to the consolidated financial statements, the FHLB Advances, Notes and Other Borrowings section of this MD&A and Off-Balance Sheet Arrangements in the MD&A of the Company's 2016 Annual Report on Form 10-K.

Critical Accounting Policies and Estimates

The Company has made no significant changes in its critical accounting policies and significant estimates from those disclosed in the 2016 Annual Report on Form 10-K.

Non-GAAP Financial Measures

Tangible book value per common share is a non-GAAP financial measure. Management believes this measure is relevant to understanding the capital position and performance of the Company. Disclosure of this non-GAAP financial measure also provides a meaningful base for comparability to other financial institutions. The following table reconciles the non-GAAP financial measurement of tangible book value per common share to the comparable GAAP financial measurement of book value per common share at June 30, 2017 (in thousands except share and per share data):




Total stockholders’ equity	$	2,580,820
Less: goodwill and other intangible assets	77,919
Tangible stockholders’ equity	$	2,502,901

Common shares issued and outstanding	106,800,972

Book value per common share	$	24.16

Tangible book value per common share	$	23.44
