Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingencies

Note 9 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 and commercial real estate lines of credit to existing customers, for many of which additional extensions of credit are subject to borrowing base requirements. Some of these commitments may mature without being fully funded, so may not necessarily represent future liquidity requirements.

Commercial and standby letters of credit

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

Total lending related commitments outstanding at June 30, 2023 were as follows (in thousands):


Commitments to fund loans	$	245,376

Unfunded commitments under lines of credit	5,559,209
Commercial and standby letters of credit	164,028
	$	5,968,613

Legal Proceedings

The Company is involved 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.

Credit quality information

Credit quality of loans held for investment is continuously monitored by dedicated residential credit risk management and commercial portfolio management functions. The Company also has a workout and recovery department that monitors the credit quality of criticized and classified loans and an independent internal credit review function.

Credit quality indicators for residential loans

Management considers delinquency status to be the most meaningful indicator of the credit quality of residential loans, other than government insured residential loans. Delinquency statistics are updated at least monthly. LTV and FICO scores are also important indicators of credit quality for 1-4 single family residential loans other than government insured loans. FICO scores are generally updated semi-annually, and were most recently updated in the first quarter of 2023. LTVs are typically at origination since we do not routinely update residential appraisals. Substantially all of the government insured residential loans are government insured buyout loans, which the Company buys out of GNMA securitizations upon default. For these loans, traditional measures of credit quality are not particularly relevant considering the guaranteed nature of the loans and the underlying business model. Factors that impact risk inherent in the residential portfolio segment include national and regional economic conditions such as levels of unemployment, wages and interest rates, as well as residential property values.

Credit quality indicators for commercial loans

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

The Company monitors its investment securities available for sale for credit loss impairment on an individual security basis. No securities were determined to be credit loss impaired during the three and six months ended June 30, 2023 and 2022. At June 30, 2023, the Company did not have an intent to sell securities that were in unrealized loss positions, and it was not more likely than not that the Company would be required to sell these securities before recovery of the amortized cost basis, which may be at maturity. In making this determination, the Company considered its current and projected liquidity position including its ability to pledge securities to generate liquidity, its investment policy as to permissible holdings and concentration limits, regulatory requirements and other relevant factors. While recent events impacting the banking sector have impacted the liquidity profile of many banks, including BankUnited, the substantial majority of our investment securities are pledgeable at either the FHLB or FRB. We have not sold, and do not anticipate the need to sell, securities in unrealized loss positions to generate liquidity.

At June 30, 2023, 578 securities available for sale were in unrealized loss positions. The amount of impairment related to 107 of these securities was considered insignificant both individually and in the aggregate, totaling approximately $1.0 million and no further analysis with respect to these securities was considered necessary.

The basis for concluding that AFS securities were not credit loss impaired and no ACL was considered necessary at June 30, 2023, is further discussed below.

Unrealized losses were generally attributable to rising interest rates and widening spreads related to the Federal Reserve's quantitative tightening and benchmark interest rate increases. Continuing uncertainty with respect to the trajectory of the economy has also led to market uncertainty, producing some yield curve dislocations. The investment securities AFS portfolio was in a net unrealized loss position of $599.4 million at June 30, 2023, compared to $674.2 million at December 31, 2022, improving by $75 million during the six months ended June 30, 2023 .

U.S. Government, U.S. Government Agency and Government Sponsored Enterprise Securities

At June 30, 2023, six U.S. treasury, 153 U.S. Government agency and sponsored enterprise residential MBS, 26 U.S. Government agency and sponsored enterprise commercial MBS, and 18 SBA securities were in unrealized loss positions. The timely payment of principal and interest on these securities is explicitly or implicitly guaranteed by the U.S. Government. As such, there is an assumption of zero credit loss and the Company expects to recover the amortized cost basis of these securities.

Private Label Securities:

None of the impaired private label securities had missed principal or interest payments or had been downgraded by a NRSRO at June 30, 2023. The Company performed an analysis comparing the present value of cash flows expected to be collected to the amortized cost basis of impaired securities. This analysis was based on a scenario that we believe to be generally more conservative than our reasonable and supportable economic forecast at June 30, 2023, and incorporated assumptions about voluntary prepayment rates, collateral defaults, delinquencies, severity and other relevant factors as described further below. Our analysis also considered the structural characteristics of each security and the level of credit enhancement provided by that structure.

Private label residential MBS and CMOs

At June 30, 2023, 117 private label residential MBS and CMOs were in unrealized loss positions. Our analysis of cash flows expected to be collected on these securities incorporated assumptions about collateral default rates, voluntary prepayment rates, loss severity, delinquencies and recovery lag. In developing those assumptions, we took into account collateral quality measures such as FICO, LTV, documentation, loan type, property type, agency availability criteria and performing status. We also regularly monitor sector data including home price appreciation, forbearance, delinquency and prepay trends as well as other economic data that could be indicative of stress in the sector. Our June 30, 2023 analysis projected weighted average collateral losses for impaired securities in this category of 2% compared to weighted average credit support of 18%. As of June 30, 2023, 94% of impaired securities in this category, based on carrying value, were externally rated AAA, 4% were rated AA and 2% were rated A.

Private label commercial MBS

At June 30, 2023, 97 private label commercial MBS were in unrealized loss positions. Our analysis of cash flows expected to be collected on these securities incorporated assumptions about collateral default rates, voluntary prepayment rates, loss severity, delinquencies and recovery lag. In developing those assumptions, we took into account collateral quality and type, loan size, loan purpose and other qualitative factors. We also regularly monitor collateral watch lists, bankruptcy data, defeasance data, special servicing trends, delinquency and other economic data that could be indicative of stress in the sector. Our June 30, 2023 analysis projected weighted average collateral losses for impaired securities in this category of 7% compared to weighted average credit support of 43%. As of June 30, 2023, 84% of impaired securities in this category, based on carrying value, were externally rated AAA, 11% were rated AA and 5% were rated A.

Single family real estate-backed securities

At June 30, 2023, 16 single family rental real estate-backed securities were in unrealized loss positions. Our analysis of cash flows expected to be collected on these securities incorporated assumptions about collateral default rates, loss severity, delinquencies and recovery lag. We regularly monitor sector data including home price appreciation, forbearance, delinquency and prepay trends as well as other economic data that could be indicative of stress in the sector. Our June 30, 2023 analysis projected weighted average collateral losses for this category of 8% compared to weighted average credit support of 52%. As of June 30, 2023, 64% of impaired securities in this category, based on carrying value, were externally rated AAA, 14% were rated AA and one security was not externally rated.

Collateralized loan obligations

At June 30, 2023, 26 collateralized loan obligations were in unrealized loss positions. Our analysis of cash flows expected to be collected on these securities incorporated assumptions about collateral default rates, loss severity, and delinquencies, calibrated to take into account idiosyncratic risks associated with the underlying collateral. In developing those assumptions, we took into account each sector’s performance pre-, during and post the 2008 financial crisis. We regularly engage with bond managers to monitor trends in underlying collateral including potential downgrades and subsequent cash flow diversions, liquidity, ratings migration, and any other relevant developments. Our June 30, 2023 analysis projected weighted average collateral losses for impaired securities in this category of 11% compared to weighted average credit support of 44%. As of June 30, 2023, 81% of the impaired securities in this category, based on carrying value, were externally rated AAA, 15% were rated AA and 4% were rated A.

Non-mortgage asset-backed securities

At June 30, 2023, seven non-mortgage asset-backed securities were in unrealized loss positions. These securities are backed by student loan collateral. Our analysis of cash flows expected to be collected on these securities incorporated assumptions about collateral default rates, loss severity, delinquencies, voluntary prepayment rates and recovery lag. In developing assumptions, we took into account collateral type, delineated by whether collateral consisted of loans to borrowers in school, refinancing, or a mixture. Our June 30, 2023 analysis projected weighted average collateral losses for impaired securities in this category of 4% compared to weighted average credit support of 24%. As of June 30, 2023, 46% of the impaired securities in this category, based on carrying value, were externally rated AAA, and 54% were rated AA.

State and Municipal Obligations

At June 30, 2023, five state and municipal obligations were in unrealized loss positions. Our analysis of potential credit loss impairment for these securities incorporates a quantitative measure of the underlying obligor's credit worthiness provided by a third-party vendor as well as other relevant qualitative considerations. As of June 30, 2023, 93% of the impaired securities in this category, based on carrying value, were externally rated AAA, and 7% were rated AA

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Summary of Significant Accounting Policies	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 banking centers in Florida, the New York metropolitan area and Dallas, Texas. The Bank also offers certain commercial lending and deposit products through national platforms and regional wholesale banking offices. The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X of the SEC. 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, 2022 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, 2023 are not necessarily indicative of the results that may be expected in future periods. The Company has a single operating segment and thus a single reportable segment. While management monitors the revenue streams of its various business units, the business units serve a similar base of primarily commercial clients, providing a similar range of products and services, managed through similar processes and platforms. The Company’s chief operating decision maker makes company-wide resource allocation decisions and assessments of performance based on a collective assessment of the Company’s operations. 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. The most significant estimate impacting the Company's consolidated financial statements is the ACL. New Accounting Pronouncements Adopted During the Six Months Ended June 30, 2023 ASU No. 2022-02, Financial Instruments—Credit Losses (Topic 326). This ASU eliminated the accounting guidance for TDRs by creditors in Subtopic 310-40, Receivables - Troubled Debt Restructurings by Creditors. The ASU enhanced disclosure requirements for certain loan refinancings and restructurings by creditors when a borrower is experiencing financial difficulty, updated certain requirements related to accounting for credit losses under ASC 326 and required disclosure of current-period gross charge-offs of financing receivables by year of origination. The Company adopted this ASU in the first quarter of 2023, prospectively, except with respect to the recognition and measurement of TDRs, for which the modified retrospective transition method was applied. The Company recorded a reduction to the ACL of $1.8 million and a cumulative-effect adjustment, net of tax, to retained earnings of $1.3 million on January 1, 2023. Accounting Pronouncements Not Yet Adopted ASU No. 2023-02—Investments - Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures using the Proportional Amortization Method (A Consensus of the Emerging Issues Task Force). This ASU was issued to expand use of the proportional amortization method of accounting to equity investments in tax credit programs beyond those in LIHTC programs. The ASU allows entities to elect the proportional amortization method, on a tax-credit-program-by-tax-credit-program basis, for all equity investments in tax credit programs meeting the eligibility criteria established. This ASU is effective for the Company for interim and annual periods in fiscal years beginning after December 15, 2023. Currently, all of the Company's equity investments in tax credit programs are in LIHTC programs accounted for using the proportional amortization method

Income Taxes	6 Months Ended
Income Taxes	Jun. 30, 2022
Income Tax Disclosure [Abstract]
Income Taxes	Note 5 Income TaxesThe Company’s effective income tax rate was 26.2% and 26.3% for the three and six months ended June 30, 2023, respectively, and 24.8% and 24.6% for the three and six months ended June 30, 2022, respectively. The effective income tax rates differed from the statutory federal income tax rate of 21% for the three and six months ended June 30, 2023 and 2022 due primarily to the impact of state income taxes, partially offset by the benefit of income not subject to federal tax

- Definition

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.

Derivatives and Hedging Activities

Derivative Financial Instruments

Derivatives designated as hedging instruments

The Company has entered into interest rate swaps, caps and collars designated as cash flow hedges with the objective of limiting the variability of interest payment cash flows. The Company has also entered into interest rate swaps designated as fair value hedges designed to hedge changes in the fair value of outstanding fixed rate instruments caused by fluctuations in the benchmark interest rate. Changes in fair value of derivative instruments designated as cash flow hedges are reported in accumulated other comprehensive income. Changes in the fair value of derivative instruments designated as fair value hedges are recognized in earnings, as is the offsetting gain or loss on the hedged item.

The following table summarizes the Company's derivatives designated as hedging instruments as of the dates indicated (in thousands):


	June 30, 2023						December 31, 2022

During the three and six months ended June 30, 2023 and 2022, 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, 2023, the amount of net gain expected to be reclassified from AOCI into earnings during the next twelve months was $56.8 million. See Note 7 to the consolidated financial statements for additional information about the reclassification adjustments from AOCI into earnings.

Derivatives designated as fair value hedges

The amount of gain (loss) related to derivatives designated as fair value hedges recognized in earnings was insignificant for the three and six months ended June 30, 2023 and 2022. The following table provides information about the hedged items related to derivatives designated as fair value hedges at the date indicated (in thousands):

Derivatives not designated as hedging instruments

The Company 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. For the three and six months ended June 30, 2023 and 2022, the impact on earnings related to changes in fair value of these derivatives was not material.

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

The following table summarizes the Company's derivatives not designated as hedging instruments as of the dates indicated (in thousands):

(1) Fair values of these derivatives are included in other assets and other liabilities in the consolidation balance sheets.

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.

Fair Value Measurements

Note 8 Fair Value Measurements

Assets and liabilities measured at fair value on a recurring basis

The 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, non-mortgage asset-backed securities, single family real estate-backed securities, 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.

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. Any price discrepancies are resolved based on careful consideration of the assumptions and inputs employed by each of the pricing sources.

Derivative financial instruments—Fair values of interest rate swaps, caps and collars 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 benchmark swap rates and benchmark forward yield curves. These fair value measurements are generally classified within level 2 of the fair value hierarchy.

The following tables present assets and liabilities measured at fair value on a recurring basis at the dates indicated (in thousands):

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.

Collateral dependent loans and OREO—The carrying amount of collateral dependent loans is typically based on the fair value of the underlying collateral, which may be real estate, enterprise value or other business assets, less estimated costs to sell when repayment is expected to come from the sale of the collateral. The carrying value of OREO is initially measured based on the fair value of the real estate acquired in foreclosure and subsequently adjusted to the lower of cost or estimated fair value, less estimated cost to sell. Fair values of real estate collateral and OREO are typically based on third-party real estate appraisals which utilize market and income approaches to valuation incorporating both observable and unobservable inputs.

Fair value measurements related to collateral dependent loans and OREO are generally classified within level 3 of the fair value hierarchy.
