Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Significant Accounting Policies [Text Block]	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 77 banking centers located in 14 Florida counties and 5 banking centers located in the New York metropolitan area at September 30, 2019. The Bank also offers certain commercial lending and deposit products through national platforms. The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X of the SEC. Accordingly, these do not include all of the information and footnotes required for a fair presentation of financial position, results of operations and cash flows in conformity with GAAP and should be read in conjunction with the Company’s consolidated financial statements and the notes thereto appearing in BKU’s Annual Report on Form 10-K for the year ended December 31, 2018 filed with the SEC. In the opinion of management, all adjustments, consisting of normal recurring adjustments, considered necessary for a fair presentation have been included. Operating results for the three and nine months ended September 30, 2019 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 and the fair values of investment securities and other financial instruments. New Accounting Pronouncements Adopted During the Nine Months Ended September 30, 2019 ASU No. 2016-02, Leases (Topic 842). The amendments in this ASU, along with subsequent ASUs issued to clarify certain provisions of Topic 842, require a lessee to recognize in the statement of financial position a liability to make lease payments and a right-of-use asset representing its right to use the underlying asset for leases with terms longer than one year. Accounting applied by lessors was largely unchanged by this ASU. The ASU also requires both qualitative and quantitative disclosures that provide additional information about the amounts recorded in the consolidated financial statements. The amendments in this ASU were effective for the Company for interim and annual periods in fiscal years beginning after December 15, 2018. The most significant impact of adoption was the recognition, as lessee, of new right-of-use assets and lease liabilities on the Consolidated Balance Sheet for real estate leases classified as operating leases. Under a package of practical expedients that the Company elected, as lessee and lessor, the Company did not have to (i) re-assess whether expired or existing contracts contain leases, (ii) re-assess the classification of expired or existing leases, (iii) re-evaluate initial direct costs for existing leases or (iv) separate lease components of certain contracts from non-lease components. The Company also elected the transition method that allows entities the option of applying the provisions of the ASU at the effective date without adjusting the comparative periods presented. The Company adopted this ASU in the first quarter of 2019 using the modified retrospective transition method. The Company recognized a lease liability and related right of use asset of approximately $104 million and $95 million, respectively, upon adoption on January 1, 2019. ASU No. 2018-16, Derivatives and Hedging (Topic 815): Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes. The ASU added the OIS rate based on SOFR as a benchmark interest rate for hedge accounting purposes. The ASU was effective for the Company for interim and annual periods in fiscal years beginning after December 15, 2018. The Company adopted this ASU in the first quarter of 2019 with no impact at adoption to its consolidated financial position, results of operations, or cash flows. Leases The Company determines whether a contract is or contains a lease at inception. For leases with terms greater than twelve months under which the Company is lessee, ROU assets and lease liabilities are recorded at the commencement date. Lease liabilities are initially recorded based on the present value of future lease payments over the lease term. ROU assets are initially recorded at the amount of the associated lease liabilities plus prepaid lease payments and initial direct costs, less any lease incentives received. The cost of short term leases is recognized on a straight line basis over the lease term. The lease term includes options to extend if the exercise of those options is reasonably certain and includes termination options if there is reasonable certainty the options will not be exercised. Lease payments are discounted using the Company's FHLB borrowing rate for borrowings of a similar term unless an implicit rate is defined in the contract or is determinable, which is generally not the case. Leases are classified as financing or operating leases at commencement; generally, leases are classified as finance leases when effective control of the underlying asset is transferred. The substantial majority of leases under which the Company is lessee are classified as operating leases. For operating leases, lease cost is recognized in the Consolidated Statements of Income on a straight line basis over the lease terms. For finance leases, interest expense on lease liabilities is recognized on the effective interest method and amortization of ROU assets is recognized on a straight line basis over the lease terms. Variable lease costs are recognized in the period in which the obligation for those costs is incurred. The Company has elected not to separate lease from non-lease components of its lease contracts.

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 nine months ended September 30, 2019 or 2018. The Company does not intend to sell securities that are in significant unrealized loss positions at September 30, 2019 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 September 30, 2019, 115 securities available for sale were in unrealized loss positions. The amount of impairment related to 41 of these securities was considered insignificant both individually and in the aggregate, totaling approximately $346 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 and commercial MBS

At September 30, 2019, twenty-seven 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. Impairment of these floating rate securities was primarily attributable to widening spreads. 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 September 30, 2019, six private label residential MBS and CMOs were in unrealized loss positions, primarily as a result of widening spreads. 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 September 30, 2019. Given the expectation of timely recovery of outstanding principal the impairments were considered to be temporary.

Private label commercial MBS

At September 30, 2019, five private label commercial MBS were in unrealized loss positions, primarily as a result of widening spreads. 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 expectation of timely recovery of outstanding principal the impairments were considered to be temporary.

Single family rental real estate-backed securities

At September 30, 2019, five single family rental real estate-backed securities were in unrealized loss positions. The unrealized losses were primarily due to widening spreads. 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 absence of projected credit losses the impairments were considered to be temporary.

Collateralized loan obligations:

At September 30, 2019, seventeen collateralized loan obligations were in unrealized loss positions, primarily due to widening spreads for this asset class. 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 expectation of timely recovery of outstanding principal, the impairments were considered to be temporary.

Non-mortgage asset-backed securities

At September 30, 2019, two non-mortgage asset-backed securities were in unrealized loss positions, due primarily to widening spreads. These securities were assessed for OTTI using a credit and prepayment behavioral model incorporating assumptions consistent with the collateral characteristics of the security. The results of this analysis were not indicative of expected credit losses. Given the expectation of timely recovery of outstanding principal, the impairment was considered to be temporary.

SBA Securities

At September 30, 2019, eight SBA securities were in unrealized loss positions. These securities were purchased at a premium and the impairment was attributable primarily to increased prepayment speeds. The timely payment of principal and interest on these securities is guaranteed by the SBA. Given the expectation of timely payment of principal and interest, the impairments were considered to be temporary.

Credit quality information

Loans, other than ACI loans and government insured residential loans, are considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due, according to the contractual terms of the loan agreements. Commercial relationships with committed balances

greater than or equal to $1.0 million that have internal risk ratings of substandard or doubtful and are on non-accrual status, 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.

An ACI pool or loan is considered to be impaired when it is probable that the Company will be unable to collect all the cash flows expected at acquisition, plus additional cash flows expected to be collected arising from changes in estimates after acquisition. 1-4 single family residential and home equity ACI loans accounted for in pools are evaluated collectively for impairment on a pool by pool basis based on expected pool cash flows. Commercial ACI loans are individually evaluated for impairment based on expected cash flows from the individual loans. Discount continues to be accreted on ACI loans or pools as long as there are expected future cash flows in excess of the current carrying amount of the loans or pools.

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 1-4 single family residential loans other than the FSB loans and government insured loans.

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.

The following tables summarize key indicators of credit quality for the Company's loans at the dates indicated. Amounts include premiums, discounts and deferred fees and costs (in thousands):

Equipment under operating lease consists primarily of railcars, non-commercial aircraft and other transportation equipment leased to commercial end users. Original lease terms generally range from three to ten years. Asset risk is evaluated and managed by a dedicated internal staff of seasoned equipment finance professionals with a broad depth and breadth of experience in the leasing business. Additionally, we have partnered with an industry leading, experienced service provider who provides fleet management and servicing relating to the railcar fleet. Residual risk is managed by setting appropriate residual values at inception and systematic reviews of residual values based on independent appraisals, performed at least annually. We endeavor to lease to a stable end-user base, maintain a relatively young and diversified fleet of assets and stagger lease maturities.

Income Taxes	Note 6 Income Taxes The Company’s effective income tax rate was 24.1% and 25.3% for the three and nine months ended September 30, 2019, respectively, and 18.0% and 21.4% for the three and nine months ended September 30, 2018, respectively. The effective income tax rate differed from the statutory federal income tax rate of 21% for the three and nine months ended September 30, 2019 and 2018 due primarily to the impact of state income taxes, partially offset by the benefit of income not subject to federal tax.

Derivatives and Hedging Activities

Derivative Instruments and Hedging Activities Disclosure [Abstract]

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. Changes in the fair value of interest rate swaps designated as cash flow hedging instruments are 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 swaps to hedge changes in the fair value of outstanding fixed rate borrowings caused by fluctuations in interest rates; these instruments are designated as fair value hedges. Changes in the fair value of interest rate swaps designated as fair value hedging instruments as well as changes in the fair value of the hedged items caused by fluctuations in interest rates are recognized in 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 was $1.3 million and $4.3 million, respectively, for the three and nine months ended September 30, 2019 and $0.5 million and $1.2 million, respectively, for the three and nine months ended September 30, 2018.

The Company may be exposed to credit risk in the event of non-performance by the counterparties to its interest rate derivative agreements. The Company assesses the credit risk of its financial institution counterparties by monitoring publicly available credit rating and financial information. The Company manages dealer credit risk by entering into interest rate derivatives only with primary and highly rated counterparties, the use of ISDA master agreements, central clearing mechanisms and counterparty limits. The agreements contain bilateral collateral arrangements with the amount of collateral to be posted generally governed by the settlement value of outstanding swaps. The Company manages the risk of default by its commercial borrower counterparties through its normal loan underwriting and credit monitoring policies and procedures. The Company does not currently anticipate any losses from failure of interest rate derivative counterparties to honor their obligations.

The CME legally characterizes variation margin payments for centrally cleared derivatives as settlements of the derivatives' exposures rather than collateral. As a result, the variation margin payment and the related derivative instruments are considered a single unit of account for accounting and financial reporting purposes. The Company's clearing agent for interest rate derivative contracts centrally cleared through the CME settles the variation margin daily with the CME; therefore, those interest rate derivative contracts the Company clears through the CME are reported at a fair value of approximately zero at September 30, 2019 and December 31, 2018.

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 September 30, 2019, the Company had pledged net financial collateral of $25.0 million as collateral for interest rate swaps in a liability position that are not centrally cleared. The amount of collateral required to be posted varies based on the settlement value of outstanding swaps and in some cases may include initial margin requirements.

In January 2019, the Company's Board of Directors authorized a now completed share repurchase program under which the Company repurchased approximately 4.4 million shares of its common stock during the nine months ended September 30, 2019 for an aggregate purchase price of $150 million, at a weighted average price of $34.39 per share.

In September 2019, the Company's Board of Directors authorized a new share repurchase program under which the Company may repurchase up to an additional $150 million in shares of its outstanding common stock. Any repurchases will be made in accordance with applicable securities laws from time to time in open market or private transactions. The extent to which the Company repurchases shares, and the timing of such repurchases, will depend upon a variety of factors, including market conditions, the Company's capital position and amount of retained earnings, regulatory requirements and other considerations. No time limit was set for completion of the share repurchase program and the program may be suspended or discontinued at any time.

Fair Value Disclosures [Abstract]

Fair Value Measurements

Assets and liabilities measured at fair value on a recurring basis

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

Investment securities available for sale and marketable equity securities—Fair value measurements are based on quoted prices in active markets when available; these measurements are classified within level 1 of the fair value hierarchy. These securities typically include U.S. Treasury securities and certain preferred stocks. If quoted prices in active markets are not available, fair values are estimated using quoted prices of securities with similar characteristics, quoted prices of identical securities in less active markets, discounted cash flow techniques, or matrix pricing models. These securities are generally classified within level 2 of the fair value hierarchy and include U.S. Government agency securities, U.S. Government agency and sponsored enterprise MBS, preferred stock investments for which level 1 valuations are not available, corporate debt securities, non-mortgage asset-backed securities, single family rental real estate-backed securities, certain private label

residential MBS and CMOs, private label commercial MBS, collateralized loan obligations and state and municipal obligations. Pricing of these securities is generally primarily spread driven. Observable inputs that may impact the valuation of these securities include benchmark yield curves, credit spreads, reported trades, dealer quotes, bids, issuer spreads, current rating, historical constant prepayment rates, historical voluntary prepayment rates, structural and waterfall features of individual securities, published collateral data, and for certain securities, historical constant default rates and default severities. Investment securities available for sale generally classified within level 3 of the fair value hierarchy include certain private label MBS and trust preferred securities. The Company typically values these securities using third-party proprietary pricing models, primarily discounted cash flow valuation techniques, which incorporate both observable and unobservable inputs. Unobservable inputs that may impact the valuation of 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.

Derivative financial instruments—Fair values of interest rate swaps are determined using widely accepted discounted cash flow modeling techniques. These discounted cash flow models use projections of future cash payments and receipts that are discounted at mid-market rates. Observable inputs that may impact the valuation of these instruments include LIBOR swap rates and LIBOR forward yield curves. These fair value measurements are generally classified within level 2 of the fair value hierarchy.

Gains on private label residential MBS recognized in net income during the three and nine months ended September 30, 2019 and 2018 are included in the consolidated statement of income line item "Gain on investment securities, net." Changes in the fair value of servicing rights are included in the consolidated statement of income line item “Other non-interest income.” Changes in fair value include changes due to valuation assumptions, primarily discount rates and prepayment speeds, as well as other changes such as runoff and the passage of time. The amount of net unrealized gains (losses) included in earnings for the nine months ended September 30, 2019 and 2018 that were related to servicing rights held at September 30, 2019 and 2018 was approximately $(0.7) million and $0.4 million, respectively, and were primarily due to changes in discount rates and prepayment speeds.

Securities for which fair value measurements are categorized in level 3 of the fair value hierarchy at September 30, 2019 consisted of pooled trust preferred securities with a fair value of $4 million and private label residential MBS and CMOs with a fair value of $20 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. Substantially all of these securities have variable rate coupons. Weighted average subordination levels at September 30, 2019 were 20.0% and 12.8% for investment grade and non-investment grade securities, respectively.

The following table provides information about the valuation techniques and unobservable inputs used in the valuation of private label residential MBS and CMOs falling within level 3 of the fair value hierarchy as of September 30, 2019 (dollars in thousands):



	Fair Value at		Valuation Technique	Unobservable Input	Range (Weighted Average)
	September 30, 2019		Valuation Technique	Unobservable Input	Range (Weighted Average)
Investment grade	$	12,244	Discounted cash flow	Voluntary prepayment rate	4.00% - 35.18% (15.37%)
				Probability of default	0.10% - 10.00% (2.01%)
				Loss severity	15.00% - 100.00% (41.93%)
				Discount rate	2.07% - 5.84% (3.08%)

Non-investment grade	$	8,068	Discounted cash flow	Voluntary prepayment rate	8.03% - 25.94% (16.24%)
				Probability of default	0.20% - 6.00% (2.15%)
				Loss severity	15.00% - 100.00% (25.38%)
				Discount rate	2.25% - 13.45% (5.10%)

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

The following table provides information about the valuation techniques and significant unobservable inputs used in the valuation of servicing rights as of September 30, 2019 (dollars in thousands):



	Fair Value at		Valuation Technique	Unobservable Input	Range (Weighted Average)
	September 30, 2019		Valuation Technique	Unobservable Input	Range (Weighted Average)
Commercial servicing rights	$	8,631	Discounted cash flow	Prepayment rate	3.16% - 22.13% (14.80%)
				Discount rate	5.24% - 25.99% (13.09%)

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 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 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.

Fair value measurements related to collateral dependent impaired loans, OREO and other repossessed assets are classified within levels 2 and 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):



	September 30, 2019								Losses from Fair Value Changes

Impaired loans	$	—	$	61,029	$	22,436	$	83,465	$	(1,552	)	$	(14,510	)

Included in the tables above are impaired taxi medallion loans with carrying values of $61.0 million at September 30, 2018. Losses from fair value changes included in the tables above include $11.7 million recognized on impaired taxi medallion loans during the nine months ended September 30, 2018. In addition, OREO and repossessed assets reported above included repossessed taxi medallions with carrying values of $1.3 million at September 30, 2018. Losses of $0.2 million and $0.6 million were recognized on repossessed taxi medallions during the three and nine months ended September 30, 2018, respectively.

Commitments and Contingencies

Sep. 30, 2019

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingencies

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

Commitments to fund loans

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

Unfunded commitments under lines of credit

Unfunded commitments under lines of credit include commercial, commercial real estate, 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 September 30, 2019 were as follows (in thousands):



Commitments to fund loans	$	713,537
Commitments to purchase loans	710,704
Unfunded commitments under lines of credit	2,795,181
Commercial and standby letters of credit	86,356
	$	4,305,778

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.

Basis of Presentation and Summary of Significant Accounting Policies (Policies)	9 Months Ended
	Sep. 30, 2019
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Leases, Policy [Table Text Block]	Leases The Company determines whether a contract is or contains a lease at inception. For leases with terms greater than twelve months under which the Company is lessee, ROU assets and lease liabilities are recorded at the commencement date. Lease liabilities are initially recorded based on the present value of future lease payments over the lease term. ROU assets are initially recorded at the amount of the associated lease liabilities plus prepaid lease payments and initial direct costs, less any lease incentives received. The cost of short term leases is recognized on a straight line basis over the lease term. The lease term includes options to extend if the exercise of those options is reasonably certain and includes termination options if there is reasonable certainty the options will not be exercised. Lease payments are discounted using the Company's FHLB borrowing rate for borrowings of a similar term unless an implicit rate is defined in the contract or is determinable, which is generally not the case. Leases are classified as financing or operating leases at commencement; generally, leases are classified as finance leases when effective control of the underlying asset is transferred. The substantial majority of leases under which the Company is lessee are classified as operating leases. For operating leases, lease cost is recognized in the Consolidated Statements of Income on a straight line basis over the lease terms. For finance leases, interest expense on lease liabilities is recognized on the effective interest method and amortization of ROU assets is recognized on a straight line basis over the lease terms. Variable lease costs are recognized in the period in which the obligation for those costs is incurred. The Company has elected not to separate lease from non-lease components of its lease contracts.
Use of Estimates, Policy [Policy Text Block]	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 and the fair values of investment securities and other financial instruments.
New Accounting Pronouncements, Policy [Policy Text Block]	New Accounting Pronouncements Adopted During the Nine Months Ended September 30, 2019 ASU No. 2016-02, Leases (Topic 842). The amendments in this ASU, along with subsequent ASUs issued to clarify certain provisions of Topic 842, require a lessee to recognize in the statement of financial position a liability to make lease payments and a right-of-use asset representing its right to use the underlying asset for leases with terms longer than one year. Accounting applied by lessors was largely unchanged by this ASU. The ASU also requires both qualitative and quantitative disclosures that provide additional information about the amounts recorded in the consolidated financial statements. The amendments in this ASU were effective for the Company for interim and annual periods in fiscal years beginning after December 15, 2018. The most significant impact of adoption was the recognition, as lessee, of new right-of-use assets and lease liabilities on the Consolidated Balance Sheet for real estate leases classified as operating leases. Under a package of practical expedients that the Company elected, as lessee and lessor, the Company did not have to (i) re-assess whether expired or existing contracts contain leases, (ii) re-assess the classification of expired or existing leases, (iii) re-evaluate initial direct costs for existing leases or (iv) separate lease components of certain contracts from non-lease components. The Company also elected the transition method that allows entities the option of applying the provisions of the ASU at the effective date without adjusting the comparative periods presented. The Company adopted this ASU in the first quarter of 2019 using the modified retrospective transition method. The Company recognized a lease liability and related right of use asset of approximately $104 million and $95 million, respectively, upon adoption on January 1, 2019. ASU No. 2018-16, Derivatives and Hedging (Topic 815): Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes. The ASU added the OIS rate based on SOFR as a benchmark interest rate for hedge accounting purposes. The ASU was effective for the Company for interim and annual periods in fiscal years beginning after December 15, 2018. The Company adopted this ASU in the first quarter of 2019 with no impact at adoption to its consolidated financial position, results of operations, or cash flows.
