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., with total consolidated assets of $35.8 billion at December 31, 2021, is a 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 commercial lending and both commercial and consumer deposit services through 63 banking centers located in 13 Florida counties and 4 banking centers in the New York metropolitan area. The Bank also provides certain commercial lending and deposit products through national platforms. The consolidated financial statements have been prepared in accordance with GAAP and prevailing practices in the banking industry. 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. Principles of Consolidation The consolidated financial statements include the accounts of BankUnited, Inc. and its wholly-owned subsidiary. All significant intercompany balances and transactions have been eliminated in consolidation. VIEs are consolidated if the Company is the primary beneficiary; i.e., has (i) the power to direct the activities of the VIE that most significantly impact the VIE's economic performance and (ii) the obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE. The Company has variable interests in affordable housing limited partnerships that are not required to be consolidated because the Company is not the primary beneficiary. Fair Value Measurements Certain of the Company's assets and liabilities are reflected in the consolidated financial statements at fair value on either a recurring or non-recurring basis. Investment securities available for sale, marketable equity securities, servicing rights and derivative instruments are measured at fair value on a recurring basis. Assets measured at fair value or fair value less cost to sell on a non-recurring basis may include collateral dependent loans, OREO and other repossessed assets, loans held for sale, goodwill and impaired long-lived assets. These non-recurring fair value measurements typically involve lower-of-cost-or-market accounting or the measurement of impairment of certain assets. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the measurement date. GAAP establishes a hierarchy that prioritizes inputs used to determine fair value measurements into three levels based on the observability and transparency of the inputs: • Level 1 inputs are unadjusted quoted prices in active markets that are accessible at the measurement date for identical assets or liabilities. • Level 2 inputs are observable inputs other than level 1 inputs, including quoted prices for similar assets and liabilities, quoted prices for identical assets and liabilities in less active markets and other inputs that can be corroborated by observable market data. • Level 3 inputs are unobservable inputs supported by limited or no market activity or data and inputs requiring significant management judgment or estimation. The fair value hierarchy requires the Company to maximize the use of observable inputs and minimize the use of unobservable inputs in estimating fair value. Unobservable inputs are utilized in determining fair value measurements only to the extent that observable inputs are unavailable. The need to use unobservable inputs generally results from a lack of market liquidity and diminished observability of actual trades or assumptions that would otherwise be available to value a particular asset or liability. Cash and Cash Equivalents Cash and cash equivalents include cash and due from banks, both interest bearing and non-interest bearing, including amounts on deposit at the Federal Reserve Bank, and federal funds sold. Cash equivalents have original maturities of three months or less. For purposes of reporting cash flows, cash receipts and payments pertaining to FHLB advances with original maturities of three months or less are reported net. Investment Securities Debt securities that the Company has the positive intent and ability to hold to maturity are classified as held to maturity and reported at amortized cost. Debt securities that the Company may not have the intent to hold to maturity are classified as available-for-sale at the time of acquisition and carried at fair value with unrealized gains and losses, net of tax, excluded from earnings and reported in AOCI, a separate component of stockholders' equity. Securities classified as available-for-sale may be used as part of the Company's asset/liability management strategy and may be sold in response to liquidity needs, regulatory changes, changes in interest rates, prepayment risk or other market factors. The Company does not maintain a trading portfolio. Purchase premiums and discounts on debt securities are amortized as adjustments to yield over the expected lives of the securities, using the level yield method. Premiums are amortized to the call date for callable securities. Realized gains and losses from sales of securities are recorded on the trade date and are determined using the specific identification method. The Company's policy on the ACL related to debt securities is discussed below in the section entitled "ACL". Marketable equity securities with readily determinable fair values are reported at fair value with unrealized gains and losses included in earnings. Equity securities that do not have readily determinable fair values are reported at cost and re-measured at fair value upon occurrence of an observable price change or recognition of impairment. Non-marketable Equity Securities The Bank, as a member of the FRB system and the FHLB, is required to maintain investments in the stock of the FRB and FHLB. No market exists for this stock, and the investment can be liquidated only through redemption by the respective institutions, at the discretion of and subject to conditions imposed by those institutions. The stock has no readily determinable fair value and is carried at cost. Historically, stock redemptions have been at par value, which equals the Company's carrying value. The Company monitors its investment in FHLB stock for impairment through review of recent financial results of the FHLB, including capital adequacy and liquidity position, dividend payment history, redemption history and information from credit agencies. The Company has not identified any indicators of impairment of FHLB stock. Loans Held for Sale Loans originated or purchased with the intent to sell in the secondary market are carried at the lower of cost or fair value, determined in the aggregate. A valuation allowance is established through a charge to earnings if the aggregate fair value of such loans is lower than their cost. Gains or losses recognized upon sale are determined on the specific identification basis. Loans not originated or otherwise acquired with the intent to sell, or loans which have been originated by the Company and subsequently held for sale, are transferred into the held for sale classification at the lower of carrying amount or fair value when they are specifically identified for sale and a formal plan exists to sell them. Loans Loans are reported at amortized cost, net of the ACL. Interest income is accrued based on the principal amount outstanding. Non-refundable loan origination fees, net of direct costs of originating or acquiring loans, as well as purchase premiums and discounts, are deferred and recognized as adjustments to yield over the contractual lives of the related loans using the level yield method. Non-accrual loans Commercial loans are placed on non-accrual status when (i) management has determined that full repayment of all contractual principal and interest is in doubt, or (ii) the loan is past due 90 days or more as to principal or interest unless the loan is well secured and in the process of collection. Residential and other consumer loans, other than government insured residential loans, are generally placed on non-accrual status when they are 90 days past due. Residential loans that have rolled off of a short-term deferral related to COVID-19 and have not caught up on their deferred payments may also be placed on non-accrual; these loans are typically pending modification and are generally returned to accruing status upon modification. When a loan is placed on non-accrual status, uncollected interest accrued is reversed and charged to interest income. Payments received on non-accrual commercial loans are applied as a reduction of principal. Interest payments are recognized as income on a cash basis on non-accrual residential loans. Commercial loans are returned to accrual status only after all past due principal and interest has been collected and full repayment of remaining contractual principal and interest is reasonably assured. Residential and consumer loans are generally returned to accrual status when less than 90 days past due. Past due status of loans is determined based on the contractual next payment due date. Loans less than 30 days past due are reported as current. Contractually delinquent government insured residential loans are not classified as non-accrual due to the nature of the guarantee. Contractually delinquent PCD loans are not classified as non-accrual as long as the Company has a reasonable expectation about amounts expected to be collected. Troubled Debt Restructurings In certain situations, due to economic or legal reasons related to a borrower's financial difficulties, the Company may grant a concession to the borrower for other than an insignificant period of time that it would not otherwise consider. At that time, the related loan is classified as a TDR. The concessions granted may include rate reductions, principal forgiveness, payment forbearance, extensions of maturity at rates of interest below that commensurate with the risk profile of the loans, modification of payment terms and other actions intended to minimize economic loss. A TDR is generally placed on non-accrual status at the time of the modification unless the borrower was performing prior to the restructuring. Pursuant to inter-agency and authoritative guidance and consistent with the CARES Act, short-term (generally periods of six months or less) deferrals or modifications related to COVID-19 typically are not categorized as TDRs. The Company has elected to apply the provisions of section 4013 of the CARES Act to qualifying loan modifications, other than short-term payment deferrals of 6 months or less that are subject to the interagency guidance, that might otherwise be categorized as TDRs under ASC 310-40. Section 4013 of the CARES Act, as amended by the Consolidated Appropriations Act on December 27, 2020, effectively suspended the guidance related to TDRs codified in ASC 310-40 through January 1, 2022. PCD assets PCD assets are acquired financial assets that, as of the date of acquisition, have experienced a more than insignificant deterioration in credit quality since origination. An assessment is conducted at acquisition to determine whether acquired financial assets meet the criteria to be classified as PCD assets. That assessment may be conducted at the individual asset level, or for a group of assets acquired together that have similar risk characteristics. At acquisition, the ACL related to PCD assets, representing the estimated amount of the UPB of the assets not expected to be collected, is added to the purchase price to determine the amortized cost basis and any non-credit related discount or premium is allocated to the individual assets acquired. The non-credit related discount or premium is accreted or amortized to interest income over the life of the related assets using the level yield method, as long as there is a reasonable expectation about amounts expected to be collected. Subsequent changes in the amount of expected credit losses are recognized immediately by adjusting the ACL and reflecting the periodic changes as credit loss expense or reversal of credit loss expense. Sales-type and Direct Financing Leases Sales-type and direct financing leases are carried at the aggregate of lease payments receivable and estimated residual value of the leased property, if applicable, less unearned income. Interest income is recognized over the term of the leases to achieve a constant periodic rate of return on the outstanding investment. ACL AFS Debt Securities The Company reviews its AFS debt securities for credit loss impairment at the individual security level on at least a quarterly basis. A security is impaired if its fair value is less than its amortized cost basis. A decline in fair value below amortized cost basis represents a credit loss impairment to the extent the Company does not expect to recover the amortized cost basis of the security. Impairment related to credit losses is recorded through the ACL to the extent fair value is less than the amortized cost basis. Declines in fair value that have not been recorded through the ACL are recorded through other comprehensive income, net of applicable taxes. In assessing whether an impairment is credit loss related, the Company compares the present value of cash flows expected to be collected to the security's amortized cost basis. If the present value of cash flows expected to be collected is less than the amortized cost basis of the security, a credit loss exists and an ACL is recorded. The Company discounts expected cash flows at the effective interest rate implicit in the security at the purchase date, adjusted for expected prepayments. For floating rate securities, the Company uses the floating rate as it changes over the life of the security. In developing estimates about cash flows expected to be collected and determining whether a credit loss exists, the Company considers information about past events, current conditions and reasonable and supportable forecasts. Factors and information that the Company uses in making its assessments include, but are not necessarily limited to, the following: • The extent to which fair value is less than amortized cost; • Adverse conditions specifically related to the security, an industry or geographic area; • Changes in the financial condition of the issuer or underlying loan obligors; • The payment structure and remaining payment terms of the security, including levels of subordination or over-collateralization; • Failure of the issuer to make scheduled payments; • Changes in credit ratings; • Relevant market data; • Estimated prepayments, defaults, and the value and performance of underlying collateral at the individual security level. The relative importance assigned to each of these factors varies depending on the facts and circumstances pertinent to the individual security being evaluated. Timely payment of principal and interest on securities issued by the U.S. Government, U.S. government agencies and U.S. government sponsored entities is explicitly or implicitly guaranteed by the U. S. government. Therefore, the Company expects to recover the amortized cost basis of these securities. If the Company intends to sell a security in an unrealized loss position, or it is more likely than not that the Company will be required to sell the security before recovery of its amortized cost basis, any allowance for credit losses will be written off and the amortized cost basis will be written down to the debt security’s fair value at the reporting date with any incremental impairment reported in earnings. AFS securities will be charged off to the extent that there is no reasonable expectation of recovery of amortized cost basis. AFS securities will be placed on non-accrual status if the Company does not reasonably expect to receive interest payments in the future and interest accrued will be reversed against interest income. Securities will be returned to accrual status only when collection of interest is reasonably assured. Loans The ACL is a valuation account that is deducted from the amortized cost basis of loans to present the net amount expected to be collected. The ACL is adjusted through the provision for credit losses to the amount of amortized cost basis not expected to be collected, or in the case of PCD loans, the amount of UPB not expected to be collected, at the balance sheet date. Amortized cost basis includes UPB, unamortized premiums or discounts and deferred fees and costs, net of amounts previously charged off. The measurement of expected credit losses encompasses information about historical events, current conditions and reasonable and supportable forecasts. Determining the amount of the ACL is complex and requires extensive judgment by management about matters that are inherently uncertain. Re-evaluation of the ACL estimate in future periods, in light of changes in composition and characteristics of the loan portfolio, changes in the reasonable and supportable forecast and other factors then prevailing may result in material changes in the amount of the ACL and credit loss expense in those future periods. Loans are charged off against the ACL in the period in which they are deemed uncollectible and recoveries are credited to the ACL when received. Expected recoveries on loans previously charged off and expected to be charged-off, not to exceed the aggregate of amounts previously charged-off and expected to be charged-off, are included in the ACL estimate. For loans secured by residential real estate, an assessment of collateral value is made at no later than 120 days delinquency; any outstanding loan balance in excess of fair value less cost to sell is charged off at no later than 180 days delinquency. Additionally, any outstanding balance in excess of fair value of collateral less cost to sell is charged off (i) within 60 days of receipt of notification of filing from the bankruptcy court, (ii) within 60 days of determination of loss if all borrowers are deceased or (iii) within 90 days of discovery of fraudulent activity. Other consumer loans are typically charged off at 120 days delinquency. Commercial loans are charged off when, in management's judgment, they are considered to be uncollectible. Expected credit losses are estimated on a collective basis for groups of loans that share similar risk characteristics. Factors that may be considered in aggregating loans for this purpose include but are not necessarily limited to, product or collateral type, industry, geography, internal risk rating, credit characteristics such as credit scores or collateral values, and historical or expected credit loss patterns. For loans that do not share similar risk characteristics with other loans such as collateral dependent loans and TDRs, expected credit losses are estimated on an individual basis. Expected credit losses are estimated over the contractual terms of the loans, adjusted for expected prepayments. Expected prepayments for commercial loans are generally estimated based on the Company's historical experience. For residential loans, expected prepayments are estimated using a model that incorporates industry prepayment data, calibrated to reflect the Company's experience. The contractual term excludes expected extensions, renewals, and modifications unless either of the following applies: management has a reasonable expectation at the reporting date that a TDR will be executed with an individual borrower or the extension or renewal options are included in the original or modified contract at the reporting date and are not unconditionally cancellable by the Company. For the substantial majority of portfolio segments and subsegments, including residential loans other than government insured loans, and most commercial and commercial real estate loans, expected losses are estimated using econometric models. The models employ a factor based methodology, leveraging data sets containing extensive historical loss and recovery information by industry, geography, product type, collateral type and obligor characteristics, to estimate PD and LGD. Measures of PD for commercial loans incorporate current conditions through market cycle or credit cycle adjustments. For residential loans, the models consider FICO and adjusted LTVs. PDs and LGDs are then conditioned on the reasonable and supportable economic forecast. Projected PDs and LGDs, determined based on pool level characteristics, are applied to estimated exposure at default, considering the contractual term and payment structure of loans, adjusted for prepayments, to generate estimates of expected loss. For criticized or classified loans, PDs are adjusted to benchmark PDs established for each risk rating if the most current financial information available is deemed not to be reflective of the borrowers' current financial condition. The ACL estimate incorporates a reasonable and supportable economic forecast through the use of externally developed macroeconomic scenarios applied in the models. A single economic scenario or a probability weighted blend of economic scenarios may be used. The models ingest numerous national, regional and MSA level variables and data points. Commercial Real Estate Model Variables with the most significant impact on the commercial real estate model include unemployment at both national and regional levels, the CRE property forecast by property type and sub-market, 10 year treasury yield, Baa corporate yield and real GDP growth, at the national level. Increases in unemployment and yields within the commercial real estate model result in increases in the ACL. Increases in real GDP growth and improvements in the CRE property forecasts reduce the reserve. Commercial Model Variables with the most significant impact on the commercial model include a stock market volatility index, the S&P 500 index, unemployment, at both national and regional levels, and a variety of interest rates and spreads. Increases in the unemployment rate, the stock market volatility index, and the Baa corporate yield increase the reserve, while increases in real GDP growth reduce the reserve. Residential Model Variables with the most significant impact on the residential model include HPI and unemployment at regional levels, real GDP growth, and a 30 year mortgage rate. Increases in the unemployment rate and the 30-year mortgage rate increase the reserve, while increases in real GDP growth and HPI reduce the reserve. The length of the reasonable and supportable forecast period is evaluated at each reporting period and adjusted if deemed necessary. Currently, the Company uses a 2-year reasonable and supportable forecast period in estimating the ACL. After the reasonable and supportable forecast periods, the models effectively revert to long-term mean losses on a straight-line basis over 12 months. For certain less material portfolios including loans and leases to state and local government entities originated by Pinnacle, small balance commercial loans and consumer loans, the WARM method is used to estimate expected credit losses. Loss rates are applied to the exposure at default, after factoring in amortization and expected prepayments. For the Pinnacle portfolio, historical loss information is based on municipal historical default and recovery data, segmented by credit rating. For small balance commercial loans, historical loss information is based on the Company's historical loss experience over a five year period. For consumer loans, historical loss information is based on peer data; this portfolio subsegment is not significant. All loss estimates are conditioned as applicable on changes in current conditions and the reasonable and supportable economic forecast. Expected credit losses for the funded portion of mortgage warehouse lines of credit are estimated based primarily on the Company's historical loss experience, conditioned as applicable on changes in current conditions and the reasonable and supportable economic forecast. Generally, given the nature of these loans, losses would be expected to manifest within a very short time period after origination. The Company expects to collect the amortized cost basis of government insured residential loans and PPP loans due to the nature of the government guarantee, so the ACL is zero for these loans. Qualitative factors Quantitative models have certain inherent limitations with respect to estimating expected losses. These limitations may be more prevalent in times of rapidly changing economic conditions and forecasts. Qualitative adjustments are made to the ACL when, based on management’s judgment, there are factors impacting expected credit losses not taken into account by the quantitative calculations. Potential qualitative adjustments are categorized as follows: • Economic factors, including material uncertainties, trends and developments that, in management's judgment, may not have been considered in the reasonable and supportable economic forecast; • Credit policy and staffing, including the nature and level of policy and procedural exceptions or changes in credit policy not reflected in quantitative results, changes in the quality of underwriting and portfolio management and staff and issues identified by credit review, internal audit or regulators that may not be reflected in quantitative results; • Concentrations, considering whether the quantitative estimate adequately accounts for concentration risk in the portfolio; • Model imprecision and model validation findings; and • Other factors not adequately considered in the quantitative estimate or other qualitative categories identified by management that may materially impact the amount of expected credit losses. Collateral dependent loans Collateral dependent loans are those for which the borrower is experiencing financial difficulty and repayment is expected to be provided substantially through the operation or sale of the collateral. These loans do not typically share similar risk characteristics with other loans and expected credit losses are evaluated on an individual basis. Loans evaluated individually are not included in the collective evaluation. Estimates of expected credit losses for collateral dependent loans, whether or not foreclosure is probable, are based on the fair value of the collateral, adjusted for selling costs when repayment depends on sale of the collateral. Due to immateriality, expected credit losses for collateral dependent commercial relationships with committed balances less than $1.0 million may be estimated collectively. Troubled debt restructurings For TDRs or loans for which there is a reasonable expectation that a TDR will be executed that are not collateral dependent, the credit loss estimate is determined by comparing the net present value of expected cash flows, discounted at the loan’s original effective interest rate, to the amortized cost basis of the loan. Off-balance sheet credit exposures Expected credit losses related to off-balance sheet credit exposures are estimated over the contractual period for which the Company is exposed to credit risk via a contractual obligation to extend credit, unless that obligation is unconditionally cancellable by the Company. Expected credit losses are estimated using essentially the same methodologies employed to estimate expected credit losses on the amortized cost basis of loans, taking into consideration the likelihood and amount of additional amounts expected to be funded over the terms of the commitments. The liability for credit losses on off-balance sheet credit exposures is presented within other liabilities on the consolidated balance sheets, distinct from the ACL. Adjustments to the liability are included in the provision for credit losses. Accrued Interest Receivable The Company has elected to present accrued interest receivable separate from the amortized cost basis of financial assets carried at amortized cost. The Company excludes accrued interest receivable balances from tabular disclosures about financial assets carried at amortized cost. The Company generally does not estimate an ACL on accrued interest receivable balances since uncollectible accrued interest is timely written off in accordance with the Company's accounting policies for non-accrual loans. Under unusual circumstances, such as those presented by deferrals granted due to the COVID-19 pandemic, the Company evaluates whether its non-accrual policies continue to consistently provide for timely reversal of accrued interest receivable. If considered necessary, the Company records an allowance for uncollectible accrued interest receivable, determined using essentially the same methodologies used to estimate the ACL on the amortized cost basis of the related loans. The allowance is deducted from accrued interest receivable and presented within other assets on the consolidated balance sheets, distinct from the ACL. Changes in the ACL related to accrued interest receivable are included in the provision for credit losses. 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. Bank Owned Life Insurance Bank owned life insurance is carried at cash surrender value. Changes in cash surrender value are recorded in non-interest income. Operating Lease Equipment Operating lease equipment is carried at cost less accumulated depreciation and is depreciated to estimated residual value using the straight-line method over the lease term. Estimated residual values are re-evaluated at least annually, based primarily on current residual value appraisals. Rental revenue is recognized on a straight-line basis over the contractual term of the lease. A review for impairment of equipment under operating lease is performed at least annually or when events or changes in circumstances indicate that the carrying amount of long-lived assets may not be recoverable. Impairment of assets is determined by comparing the carrying amount to future undiscounted net cash flows expected to be generated. If an asset is impaired, the measure of impairment is the amount by which the carrying amount exceeds the fair value of the asset. Goodwill Goodwill represents the excess of consideration transferred in business combinations over the fair value of net tangible and identifiable intangible assets acquired. Goodwill is not amortized, but is
Accounting Standards Update and Change in Accounting Principle	Accounting Pronouncements Not Yet Adopted ASU No. 2020-06, Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity’s Own Equity (Subtopic 815-40) . This ASU simplifies the accounting for convertible debt and convertible preferred stock by reducing the number of accounting models for these instruments, resulting in fewer embedded conversion features being separately recognized from the host contract. Additionally, this ASU revises the criteria for determining whether contracts in an entity's own equity meet the scope exception from derivative accounting, which will change the population of contracts that are recognized as assets or liabilities. The amendments in this ASU also revise certain aspects of the guidance on calculating earnings per share with respect to convertible instruments and instruments that may be settled in the entity's own shares. This ASU is effective for the Company for interim and annual periods in fiscal years beginning after December 15, 2021. The impact of adoption of this ASU on the Company's consolidated financial position, results of operations, and cash flows is not expected to be material.

No securities were determined to be credit loss impaired during the year ended December 31, 2021. An ACL was recorded related to one private label commercial MBS security during the year ended December 31, 2020. At December 31, 2021, 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, its investment policy as to permissible holdings and concentration limits, regulatory requirements and other relevant factors. At December 31, 2021, 244 securities available for sale were in unrealized loss positions. The unrealized losses are primarily attributable to changes in interest rates and widening spreads, signaling market anticipation of changes in monetary policy. The amount of impairment related to 72 of these securities was considered insignificant both individually and in the aggregate, totaling approximately $0.6 million and no further analysis with respect to these securities was considered necessary. For U.S. Government, U.S. government agency and U.S. government sponsored enterprise securities, the timely payment of principal and interest 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 entire amortized cost basis of these securities. For all other AFS securities in a significant unrealized loss position, the Company performed an analysis by first determining the present value of cash flows expected to be collected, based on an economic scenario calibrated to be more severe than our reasonable and supportable economic forecast. The present value was then compared to the amortized cost basis to identify possible impairment. The analysis incorporated assumptions about voluntary prepayment rates, collateral defaults, delinquencies, severity, recovery lag and other relevant factors. Our analysis also considered the structural characteristics of each security and the level of credit enhancement provided by that structure.

The amortized cost basis of residential PCD loans and the related amount of non-credit discount was $65 million and $60 million, respectively at December 31, 2021 and $118 million and $115 million, respectively at December 31, 2020. The ACL related to PCD residential loans was $0.5 million and $2.8 million at December 31, 2021 and 2020, respectively. During the years ended December 31, 2021, 2020, and 2019, the Company purchased residential and other consumer loans totaling $4.8 billion, $3.2 billion and $2.2 billion, respectively. Purchases for the years ended December 31, 2021, 2020, and 2019 included $1.6 billion, $1.4 billion and $844 million, respectively, of government insured residential loans. At December 31, 2021 and 2020, the Company had pledged loans with a carrying value of approximately $10.6 billion and $9.6 billion, respectively, as security for FHLB advances and Federal Reserve discount window capacity. At December 31, 2021 and 2020, accrued interest receivable on loans, net of related ACL at December 31, 2020, totaled $98 million and $99 million, respectively, and is included in other assets in the accompanying consolidated balance sheets. The amount of interest income reversed on non-accrual loans was not material for the years ended December 31, 2021 and 2020. Allowance for credit losses Activity in the allowance for credit losses is summarized below. The balances for the year ended December 31, 2019 represent the allowance for loan and leases losses, estimated using an incurred loss methodology. The ACL at December 31, 2021 and 2020 was determined using the CECL methodology, utilizing a 2-year reasonable and supportable forecast period based on a single third-party provided economic scenario (in thousands): Years Ended December 31, 2021 2020 2019 Residential and Other Consumer Commercial Total Residential and Other Consumer Commercial Total Residential and Other Consumer Commercial Total Beginning balance $ 18,719 $ 238,604 $ 257,323 $ 11,154 $ 97,517 $ 108,671 $ 10,788 $ 99,143 $ 109,931 Impact of adoption of ASU 2016-13 N/A N/A N/A 8,098 19,207 27,305 N/A N/A N/A Balance after adoption of ASU 2016-13 N/A N/A N/A 19,252 116,724 135,976 N/A N/A N/A Provision (recovery) (9,241) (55,215) (64,456) (556) 182,895 182,339 154 8,750 8,904 Charge-offs (304) (70,946) (71,250) (31) (69,571) (69,602) — (17,541) (17,541) Recoveries 13 4,827 4,840 54 8,556 8,610 212 7,165 7,377 Ending balance $ 9,187 $ 117,270 $ 126,457 $ 18,719 $ 238,604 $ 257,323 $ 11,154 $ 97,517 $ 108,671 The decrease in the ACL from December 31, 2020 to December 31, 2021 resulted from charge-offs and the recovery of credit losses recorded during the year ended December 31, 2021. The most significant factor contributing to the recovery of provision for 2021 was improvements in economic conditions and the economic forecast. The increase in the ACL from January 1, 2020, the date of initial adoption of ASU 2016-13, to December 31, 2020 was reflective of the impact of the COVID-19 pandemic on current economic conditions, the economic forecast and on individual borrowers and portfolio sub-segments. The following table presents the components of the provision for (recovery of) credit losses for the periods indicated (in thousands): Years Ended December 31, 2021 2020 Amount related to funded portion of loans $ (64,456) $ 182,339 Amount related to off-balance sheet credit exposures (1,235) (5,572) Amount related to accrued interest receivable (1,064) 1,300 Amount related to AFS debt securities (364) 364 Total provision for (recovery of) credit losses $ (67,119) $ 178,431 Credit quality information The credit quality of the loan portfolio has been and may continue to be impacted by the COVID-19 crisis, its impact on the economy broadly and more specifically on the Company's individual borrowers. While economic conditions continue to improve, some level of uncertainty continues to exist about the full extent of this impact and the trajectory of recovery. The ultimate impact may not be fully reflected in some of the credit quality indicators disclosed below. Delinquency statistics may not be fully reflective of the impact of the COVID-19 crisis due to deferral and modification programs offered to affected borrowers. 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 and other consumer 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 at least annually, and were most recently updated in the third quarter of 2021. 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 and wages, as well as residential property values. 1-4 Single Family Residential credit exposure, excluding government insured residential loans, based on delinquency status: December 31, 2021 Amortized Cost By Origination Year 2021 2020 2019 2018 2017 Prior Total Current $ 2,884,761 $ 1,062,348 $ 395,453 $ 224,175 $ 342,414 $ 1,352,844 $ 6,261,995 30 - 59 Days Past Due 32,307 2,705 5,482 1,942 5,831 4,825 53,092 60 - 89 Days Past Due 605 — 1,750 1,988 — 1,307 5,650 90 Days or More Past Due 1,407 — 609 5,100 1,064 9,308 17,488 $ 2,919,080 $ 1,065,053 $ 403,294 $ 233,205 $ 349,309 $ 1,368,284 $ 6,338,225 December 31, 2020 Amortized Cost By Origination Year 2020 2019 2018 2017 2016 Prior Total Current $ 1,092,183 $ 645,993 $ 374,838 $ 611,377 $ 740,749 $ 1,392,192 $ 4,857,332 30 - 59 Days Past Due 17,826 5,741 2,564 927 2,913 18,880 48,851 60 - 89 Days Past Due 111 145 435 — 2,825 3,973 7,489 90 Days or More Past Due — 807 1,762 53 1,027 5,515 9,164 $ 1,110,120 $ 652,686 $ 379,599 $ 612,357 $ 747,514 $ 1,420,560 $ 4,922,836 1-4 Single Family Residential credit exposure, excluding government insured residential loans, based on LTV: December 31, 2021 Amortized Cost By Origination Year LTV 2021 2020 2019 2018 2017 Prior Total Less than 61% $ 1,222,510 $ 399,512 $ 89,078 $ 54,301 $ 111,540 $ 476,170 $ 2,353,111 61% - 70% 791,935 269,739 92,282 59,425 66,641 343,654 1,623,676 71% - 80% 899,400 395,726 212,649 111,276 145,413 518,817 2,283,281 More than 80% 5,235 76 9,285 8,203 25,715 29,643 78,157 $ 2,919,080 $ 1,065,053 $ 403,294 $ 233,205 $ 349,309 $ 1,368,284 $ 6,338,225 December 31, 2020 Amortized Cost By Origination Year LTV 2020 2019 2018 2017 2016 Prior Total Less than 61% $ 395,977 $ 143,273 $ 82,199 $ 174,223 $ 286,092 $ 487,487 $ 1,569,251 61% - 70 % 298,941 151,633 92,928 119,381 184,119 341,159 1,188,161 71% - 80% 413,003 344,998 181,852 271,605 258,931 565,781 2,036,170 More than 80% 2,199 12,782 22,620 47,148 18,372 26,133 129,254 $ 1,110,120 $ 652,686 $ 379,599 $ 612,357 $ 747,514 $ 1,420,560 $ 4,922,836 1-4 Single Family Residential credit exposure, excluding government insured residential loans, based on FICO score: December 31, 2021 Amortized Cost By Origination Year FICO 2021 2020 2019 2018 2017 Prior Total 760 or greater $ 2,230,259 $ 803,026 $ 245,942 $ 125,713 $ 254,750 $ 937,285 $ 4,596,975 720 - 759 562,763 194,068 91,276 53,576 54,080 219,561 1,175,324 719 or less 126,058 67,959 66,076 53,916 40,479 211,438 565,926 $ 2,919,080 $ 1,065,053 $ 403,294 $ 233,205 $ 349,309 $ 1,368,284 $ 6,338,225 December 31, 2020 Amortized Cost By Origination Year FICO 2020 2019 2018 2017 2016 Prior Total 760 or greater $ 843,199 $ 435,582 $ 225,292 $ 451,304 $ 549,119 $ 956,254 $ 3,460,750 720 - 759 223,831 128,875 84,602 102,859 130,592 256,703 927,462 719 or less 43,090 88,229 69,705 58,194 67,803 207,603 534,624 $ 1,110,120 $ 652,686 $ 379,599 $ 612,357 $ 747,514 $ 1,420,560 $ 4,922,836 Credit quality indicators for commercial loans Factors that impact risk inherent in commercial portfolio segments include but are not limited to levels of economic activity, health of the national and regional economy, industry trends, patterns of and trends in customer behavior that influence demand for our borrowers' products and services, and commercial real estate values. Internal risk ratings are considered the most meaningful indicator of credit quality for commercial loans. Internal risk ratings are generally indicative of the likelihood that a borrower will default, are a key factor 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. Loans exhibiting potential credit weaknesses that deserve management’s close attention and that could result in deterioration of repayment prospects at some future date if not checked or corrected 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 from current operations, project cost overruns, unreasonable construction delays, past due real estate taxes or exhausted interest reserves, are assigned an internal risk rating of substandard.

The components of deferred tax assets and liabilities were as follows at the dates indicated (in thousands): December 31, 2021 December 31, 2020 Deferred tax assets: Excess of tax basis over carrying value of acquired loans $ 19,784 $ 33,532 Allowance for credit losses 33,577 58,990 Net operating loss and tax credit carryforwards 19,466 5,450 Net unrealized loss on investment securities available for sale and cash flow hedges 5,456 16,824 Capitalized costs 26,854 2,624 Lease liability 23,137 24,250 Other 41,784 41,904 Gross deferred tax assets 170,058 183,574 Deferred tax liabilities: Lease financing, due to differences in depreciation 151,978 169,103 ROU asset 33,136 30,256 Other 7,706 4,623 Gross deferred tax liabilities 192,820 203,982 Net deferred tax liability $ (22,762) $ (20,408) Based on the evaluation of available evidence, the Company has concluded that it is more likely than not that the existing deferred tax assets will be realized. The primary factors supporting this conclusion is the amount of future taxable income that will result from the scheduled reversal of existing deferred tax liabilities and the Company's history of reported pre-tax income. At December 31, 2021, remaining net operating loss and tax credit carryforwards included federal net operating loss carryforwards in the amount of $0.7 million, expiring from 2029 through 2032, and Florida net operating loss carryforwards in the amount of $111.0 million. Florida net operating loss carryforwards consisted of $98.4 million expiring from 2030 through 2037 and $12.6 million that can be carried forward indefinitely. 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 $43 million and $50 million at December 31, 2021 and 2020, respectively. Unfunded commitments for affordable housing investments, included in other liabilities in the accompanying consolidated balance sheet, were $3 million and $4 million at December 31, 2021 and 2020, respectively. The maximum exposure to loss as a result of the Company's involvement with these limited partnerships at December 31, 2021 was approximately $79 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 years ended December 31, 2021, 2020 and 2019. The Company has a liability for unrecognized tax benefits relating to uncertain federal and state tax positions in several jurisdictions. A reconciliation of the beginning and ending amount of gross unrecognized tax benefits at the dates indicated follows (in thousands): December 31, 2021 December 31, 2020 December 31, 2019 Balance, beginning of period $ 414,203 $ 407,126 $ 116,081 Additions for tax positions related to the current year 2,175 2,117 5,352 Additions for tax positions related to prior periods 12,887 2,456 279,885 Reductions due to settlements with taxing authorities (43,782) (3,080) — Reductions due to lapse of the statute of limitations (30,394) (520) (406) 355,089 408,099 400,912 Interest and penalties (7,280) 6,104 6,214 Balance, end of period $ 347,809 $ 414,203 $ 407,126 As of December 31, 2021, 2020 and 2019, the Company had $329.3 million, $369.1 million and $368.9 million of unrecognized federal and state tax benefits, net of federal tax benefits, that if recognized would have impacted the effective tax rate. Unrecognized tax benefits related to federal and state income tax contingencies that may decrease during the 12 months subsequent to December 31, 2021 as a result of settlements with taxing authorities range from zero to $300.6 million. Interest and penalties related to unrecognized tax benefits are included in the provision for income taxes in the consolidated statements of income. At December 31, 2021 and 2020, accrued interest and penalties included in the consolidated balance sheets, net of federal tax benefits, were $10.6 million and $16.3 million, respectively. The total amounts of interest and penalties, net of federal tax benefits, recognized through income tax expense was $(5.7) million during the year ended December 31, 2021, and $4.9 million during each of the years ended December 31, 2020 and 2019. The Company and its subsidiaries file a consolidated federal income tax return as well as combined state income tax returns where combined filings are required. The federal tax returns for years 2018 through 2020 remain subject to examination in the U.S. Federal jurisdiction. State tax returns for years 2016 through 2020 remain subject to examination by certain states.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives and Hedging Activities	Note 10 Derivatives and Hedging Activities The Company has entered into interest rate swaps and caps designated as cash flow hedges with the objective of limiting the variability of interest payment cash flows. The Company may also enter into interest rate swaps designated as fair value hedges designed to hedge changes in the fair value of outstanding fixed rate borrowings caused by fluctuations in the benchmark interest rate. 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 years ended December 31, 2021, 2020 and 2019, 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 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 zero at both December 31, 2021 and 2020.

A loss of $33.4 million, net of tax, was reclassified from AOCI into earnings as a result of the discontinuance of the cash flow hedges. During the years ended December 31, 2020 and 2019, 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 December 31, 2021, the amount of net loss expected to be reclassified from AOCI into earnings during the next twelve months was $14.8 million. See Note 11 to the consolidated financial statements for information about the reclassification adjustments from AOCI into earnings.

All shares vest in equal annual installments over a period of four years from the date of grant except shares granted to the Company's Board of Directors, which vest over a period of one year. The following table summarizes the closing price of the Company's stock on the date of grant for shares granted and the aggregate grant date fair value of shares vesting for the periods indicated (in thousands, except per share data): Years Ended December 31, 2021 2020 2019 Range of the closing price on date of grant $42.01 - $47.52 $13.99 - $30.90 $31.07 - $36.65 Aggregate grant date fair value of shares vesting $ 16,319 $ 18,654 $ 21,064 The total unrecognized compensation cost of $28.7 million for all unvested share awards outstanding at December 31, 2021 will be recognized over a weighted average remaining period of 2.5 years. Executive share-based awards Certain of the Company's executives are eligible to receive annual awards of RSUs and PSUs (collectively, the "share units"). Annual awards of RSUs represent a fixed number of shares and vest on December 31st in equal tranches over four years. PSUs are initially granted based on a target value. The numb er of PSUs that ultimately vest at the end of the performance measurement period will be based on the achievement of performance criteria pre-established by the Compensation Committee of the Board of Directors. 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. As a result of the majority of previous settlements being in cash, all RSUs and PSUs have been determined to be liability instruments and are 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. A summary of activity related to executive share-based awards for the periods indicated follows: RSU PSU Unvested executive share-based awards outstanding, December 31, 2018 90,609 99,867 Granted 73,062 73,062 Vested (51,555) (47,841) Unvested executive share-based awards outstanding, December 31, 2019 112,116 125,088 Granted 106,731 106,731 Vested (62,292) (52,026) Unvested executive share-based awards outstanding, December 31, 2020 156,555 179,793 Granted 63,814 63,814 Vested (100,881) — Unvested executive share-based awards outstanding, December 31, 2021 119,488 243,607 The total liability for these executive share-based awards was $5.3 million at December 31, 2021. The total unrecognized compensation cost of $10.1 million for unvested executive share-based awards at December 31, 2021 will be recognized over a weighted average remaining period of 1.9 years. Incentive awards The Company's annual incentive compensation arrangements for employees other than those eligible for the executive share-based awards discussed above provide for settlement through a combination of cash payments and unvested share awards following the end of the annual performance period. The dollar value of share awards to be granted is based on the achievement of performance criteria established in the incentive arrangements. The number of shares of common stock to be awarded is variable based on the closing price of the Company's stock on the date of grant; therefore, these awards are initially classified as liability instruments, with compensation cost recognized from the beginning of the performance period. Awards vest in equal installments over a period of four years from the date of grant. No common stock was awarded pursuant to these incentive arrangements for the 2020 performance period. These awards are included in the summary of activity related to unvested share awards above.

Deferred Compensation Plan The Company has a non-qualified deferred compensation plan for a group of key management or highly compensated employees whereby a participant, upon election, may defer a portion of eligible compensation. The deferred compensation plan provides for discretionary Company contributions. Generally, the Company has elected not to make contributions. The Company credits each participant's account with income based on either an annual interest rate determined by the Company's Compensation Committee or returns of selected investment portfolios, as elected by the participant. A participant's elective deferrals and interest thereon are at all times 100% vested. Company contributions and interest thereon will become 100% vested upon the earlier of a change in control, as defined, or the participant's death, disability, attainment of normal retirement age or the completion of two years of service. Participant deferrals and any associated earnings will be paid upon separation from service or based on a specified distribution schedule, as elected by the participant. Deferred compensation expense was $2.2 million, $2.0 million and $1.9 million for the years ended December 31, 2021, 2020 and 2019, respectively. Deferred compensation liabilities of $33 million and $29 million were included in other liabilities in the accompanying consolidated balance sheets at December 31, 2021 and 2020, respectively.

Regulatory Capital Requirements under Banking Regulations [Text Block]	Note 13 Regulatory Requirements and Restrictions The Company and the Bank are subject to various regulatory capital requirements administered by Federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company's financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and the Bank must meet specific capital guidelines that involve quantitative measures of assets, liabilities and certain off-balance-sheet items calculated pursuant to regulation. The capital amounts and classification also are subject to qualitative judgments by the regulators about components, risk weightings and other factors. Banking regulations identify five capital categories for insured depository institutions: well-capitalized, adequately capitalized, undercapitalized, significantly undercapitalized and critically undercapitalized. As of December 31, 2021 and 2020, all capital ratios of the Company and the Bank exceeded the "well capitalized" levels under the regulatory framework for prompt corrective action. Quantitative measures established by regulation to ensure capital adequacy require the Company and the Bank to maintain minimum amounts and ratios of total, common equity tier 1 and tier 1 capital (as defined in the regulations) to risk-weighted assets (as defined), and of tier 1 capital to average tangible assets (leverage ratio).

BankUnited is subject to various regulatory restrictions relating to the payment of dividends, including requirements to maintain capital at or above certain minimums, and to remain "well-capitalized" under the prompt corrective action regulations. The Company does not expect that any of these laws, regulations or policies will materially affect the ability of BankUnited to pay dividends in the foreseeable future.

Fair Value Measurements	Note 14 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. 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. As all significant inputs to the valuation process are observable, these instruments are classified within level 2 of the fair value hierarchy. Derivative financial instruments —Fair values of interest rate swaps and caps 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.

Collateral dependent loans, OREO and other repossessed assets —The carrying amount of collateral dependent 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 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. 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 a combination of observable and unobservable inputs. Fair value measurements related to collateral dependent loans, OREO and other repossessed assets are generally classified within level 3 of the fair value hierarchy. Loans held for sale —Loans not originated or otherwise acquired with the intent to sell are transferred into the held for sale classification at the lower of carrying amount or fair value, typically determined based on the estimated selling price of the loans. These fair value measurements are typically classified within level 3 of the fair value hierarchy. Operating lease equipment —Fair values of impaired operating lease equipment are typically based upon discounted cash flow analyses, considering expected lease rates and estimated end of life residual values, typically obtained from independent appraisals. These fair value measurements are classified within level 3 of the fair value hierarchy. The following table presents the net carrying value of assets classified within level 3 of the fair value hierarchy at the dates indicated, for which non-recurring changes in fair value have been recorded during the year then ended (in thousands): December 31, 2021 December 31, 2020 Collateral dependent loans $ 70,433 $ 73,803 Loans held for sale — 20,500 OREO and repossessed assets 2,788 2,786 Operating lease equipment 11,429 — $ 84,650 $ 97,089 The following table presents the carrying value and fair value of financial instruments and the level within the fair value hierarchy in which those measurements are classified at the dates indicated (dollars in thousands): December 31, 2021 December 31, 2020 Level Carrying Value Fair Value Carrying Value Fair Value Assets: Cash and cash equivalents 1 $ 314,857 $ 314,857 $ 397,716 $ 397,716 Investment securities 1/2 $ 10,064,198 $ 10,064,887 $ 9,176,683 $ 9,177,870 Non-marketable equity securities 2 $ 135,859 $ 135,859 $ 195,865 $ 195,865 Loans held for sale 2 $ — $ — $ 24,676 $ 25,057 Loans, net 3 $ 23,638,596 $ 24,088,190 $ 23,608,719 $ 24,205,016 Derivative assets 2 $ 59,019 $ 59,019 $ 123,830 $ 123,830 Liabilities: Demand, savings and money market deposits 2 $ 26,053,859 $ 26,053,859 $ 22,688,617 $ 22,688,617 Time deposits 2 $ 3,384,243 $ 3,388,435 $ 4,807,199 $ 4,814,862 Federal funds purchased 2 $ 199,000 $ 199,000 $ 180,000 $ 180,000 FHLB advances 2 $ 1,905,000 $ 1,905,629 $ 3,122,999 $ 3,127,190 Notes and other borrowings 2 $ 721,416 $ 813,095 $ 722,495 $ 849,120 Derivative liabilities 2 $ 25,314 $ 25,314 $ 44,490 $ 44,490

Commitments and Contingencies	Note 15 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 and consumer 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 December 31, 2021 were as follows (in thousands): Commitments to fund loans $ 497,189 Unfunded commitments under lines of credit 3,884,978 Commercial and standby letters of credit 109,014 $ 4,491,181 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)	12 Months Ended
	Dec. 31, 2021
Organization, Consolidation and Presentation of Financial Statements [Abstract]
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.
Consolidation, Policy	Principles of Consolidation The consolidated financial statements include the accounts of BankUnited, Inc. and its wholly-owned subsidiary. All significant intercompany balances and transactions have been eliminated in consolidation. VIEs are consolidated if the Company is the primary beneficiary; i.e., has (i) the power to direct the activities of the VIE that most significantly impact the VIE's economic performance and (ii) the obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE. The Company has variable interests in affordable housing limited partnerships that are not required to be consolidated because the Company is not the primary beneficiary.
Fair Value Measurement, Policy	Fair Value Measurements Certain of the Company's assets and liabilities are reflected in the consolidated financial statements at fair value on either a recurring or non-recurring basis. Investment securities available for sale, marketable equity securities, servicing rights and derivative instruments are measured at fair value on a recurring basis. Assets measured at fair value or fair value less cost to sell on a non-recurring basis may include collateral dependent loans, OREO and other repossessed assets, loans held for sale, goodwill and impaired long-lived assets. These non-recurring fair value measurements typically involve lower-of-cost-or-market accounting or the measurement of impairment of certain assets. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the measurement date. GAAP establishes a hierarchy that prioritizes inputs used to determine fair value measurements into three levels based on the observability and transparency of the inputs: • Level 1 inputs are unadjusted quoted prices in active markets that are accessible at the measurement date for identical assets or liabilities. • Level 2 inputs are observable inputs other than level 1 inputs, including quoted prices for similar assets and liabilities, quoted prices for identical assets and liabilities in less active markets and other inputs that can be corroborated by observable market data. • Level 3 inputs are unobservable inputs supported by limited or no market activity or data and inputs requiring significant management judgment or estimation. The fair value hierarchy requires the Company to maximize the use of observable inputs and minimize the use of unobservable inputs in estimating fair value. Unobservable inputs are utilized in determining fair value measurements only to the extent that observable inputs are unavailable. The need to use unobservable inputs generally results from a lack of market liquidity and diminished observability of actual trades or assumptions that would otherwise be available to value a particular asset or liability.
Cash and Cash Equivalents, Policy	Cash and Cash Equivalents Cash and cash equivalents include cash and due from banks, both interest bearing and non-interest bearing, including amounts on deposit at the Federal Reserve Bank, and federal funds sold. Cash equivalents have original maturities of three months or less. For purposes of reporting cash flows, cash receipts and payments pertaining to FHLB advances with original maturities of three months or less are reported net.
Marketable Securities, Policy	Investment Securities Debt securities that the Company has the positive intent and ability to hold to maturity are classified as held to maturity and reported at amortized cost. Debt securities that the Company may not have the intent to hold to maturity are classified as available-for-sale at the time of acquisition and carried at fair value with unrealized gains and losses, net of tax, excluded from earnings and reported in AOCI, a separate component of stockholders' equity. Securities classified as available-for-sale may be used as part of the Company's asset/liability management strategy and may be sold in response to liquidity needs, regulatory changes, changes in interest rates, prepayment risk or other market factors. The Company does not maintain a trading portfolio. Purchase premiums and discounts on debt securities are amortized as adjustments to yield over the expected lives of the securities, using the level yield method. Premiums are amortized to the call date for callable securities. Realized gains and losses from sales of securities are recorded on the trade date and are determined using the specific identification method. The Company's policy on the ACL related to debt securities is discussed below in the section entitled "ACL". Marketable equity securities with readily determinable fair values are reported at fair value with unrealized gains and losses included in earnings. Equity securities that do not have readily determinable fair values are reported at cost and re-measured at fair value upon occurrence of an observable price change or recognition of impairment.
Nonmarketable Equity Securities	Non-marketable Equity Securities The Bank, as a member of the FRB system and the FHLB, is required to maintain investments in the stock of the FRB and FHLB. No market exists for this stock, and the investment can be liquidated only through redemption by the respective institutions, at the discretion of and subject to conditions imposed by those institutions. The stock has no readily determinable fair value and is carried at cost. Historically, stock redemptions have been at par value, which equals the Company's carrying value. The Company monitors its investment in FHLB stock for impairment through review of recent financial results of the FHLB, including capital adequacy and liquidity position, dividend payment history, redemption history and information from credit agencies. The Company has not identified any indicators of impairment of FHLB stock.
Financing Receivable, Held-for-sale	Loans Held for Sale Loans originated or purchased with the intent to sell in the secondary market are carried at the lower of cost or fair value, determined in the aggregate. A valuation allowance is established through a charge to earnings if the aggregate fair value of such loans is lower than their cost. Gains or losses recognized upon sale are determined on the specific identification basis. Loans not originated or otherwise acquired with the intent to sell, or loans which have been originated by the Company and subsequently held for sale, are transferred into the held for sale classification at the lower of carrying amount or fair value when they are specifically identified for sale and a formal plan exists to sell them.
Financing Receivable, Held-for-investment	Loans Loans are reported at amortized cost, net of the ACL. Interest income is accrued based on the principal amount outstanding. Non-refundable loan origination fees, net of direct costs of originating or acquiring loans, as well as purchase premiums and discounts, are deferred and recognized as adjustments to yield over the contractual lives of the related loans using the level yield method. Sales-type and Direct Financing Leases Sales-type and direct financing leases are carried at the aggregate of lease payments receivable and estimated residual value of the leased property, if applicable, less unearned income. Interest income is recognized over the term of the leases to achieve a constant periodic rate of return on the outstanding investment.
Loans and Leases Receivable, Nonaccrual Loan and Lease Status, Policy [Policy Text Block]	Non-accrual loans Commercial loans are placed on non-accrual status when (i) management has determined that full repayment of all contractual principal and interest is in doubt, or (ii) the loan is past due 90 days or more as to principal or interest unless the loan is well secured and in the process of collection. Residential and other consumer loans, other than government insured residential loans, are generally placed on non-accrual status when they are 90 days past due. Residential loans that have rolled off of a short-term deferral related to COVID-19 and have not caught up on their deferred payments may also be placed on non-accrual; these loans are typically pending modification and are generally returned to accruing status upon modification. When a loan is placed on non-accrual status, uncollected interest accrued is reversed and charged to interest income. Payments received on non-accrual commercial loans are applied as a reduction of principal. Interest payments are recognized as income on a cash basis on non-accrual residential loans. Commercial loans are returned to accrual status only after all past due principal and interest has been collected and full repayment of remaining contractual principal and interest is reasonably assured. Residential and consumer loans are generally returned to accrual status when less than 90 days past due. Past due status of loans is determined based on the contractual next payment due date. Loans less than 30 days past due are reported as current. Contractually delinquent government insured residential loans are not classified as non-accrual due to the nature of the guarantee. Contractually delinquent PCD loans are not classified as non-accrual as long as the Company has a reasonable expectation about amounts expected to be collected.
Troubled Debt Restructuring [Policy Text Block]	Troubled Debt Restructurings In certain situations, due to economic or legal reasons related to a borrower's financial difficulties, the Company may grant a concession to the borrower for other than an insignificant period of time that it would not otherwise consider. At that time, the related loan is classified as a TDR. The concessions granted may include rate reductions, principal forgiveness, payment forbearance, extensions of maturity at rates of interest below that commensurate with the risk profile of the loans, modification of payment terms and other actions intended to minimize economic loss. A TDR is generally placed on non-accrual status at the time of the modification unless the borrower was performing prior to the restructuring. Pursuant to inter-agency and authoritative guidance and consistent with the CARES Act, short-term (generally periods of six months or less) deferrals or modifications related to COVID-19 typically are not categorized as TDRs. The Company has elected to apply the provisions of section 4013 of the CARES Act to qualifying loan modifications, other than short-term payment deferrals of 6 months or less that are subject to the interagency guidance, that might otherwise be categorized as TDRs under ASC 310-40. Section 4013 of the CARES Act, as amended by the Consolidated Appropriations Act on December 27, 2020, effectively suspended the guidance related to TDRs codified in ASC 310-40 through January 1, 2022.
Purchased Credit Deteriorated [Policy Text Block]	PCD assets PCD assets are acquired financial assets that, as of the date of acquisition, have experienced a more than insignificant deterioration in credit quality since origination. An assessment is conducted at acquisition to determine whether acquired financial assets meet the criteria to be classified as PCD assets. That assessment may be conducted at the individual asset level, or for a group of assets acquired together that have similar risk characteristics. At acquisition, the ACL related to PCD assets, representing the estimated amount of the UPB of the assets not expected to be collected, is added to the purchase price to determine the amortized cost basis and any non-credit related discount or premium is allocated to the individual assets acquired. The non-credit related discount or premium is accreted or amortized to interest income over the life of the related assets using the level yield method, as long as there is a reasonable expectation about amounts expected to be collected. Subsequent changes in the amount of expected credit losses are recognized immediately by adjusting the ACL and reflecting the periodic changes as credit loss expense or reversal of credit loss expense.
Loans and Leases Receivable, Allowance for Loan Losses Policy [Policy Text Block]	ACL AFS Debt Securities The Company reviews its AFS debt securities for credit loss impairment at the individual security level on at least a quarterly basis. A security is impaired if its fair value is less than its amortized cost basis. A decline in fair value below amortized cost basis represents a credit loss impairment to the extent the Company does not expect to recover the amortized cost basis of the security. Impairment related to credit losses is recorded through the ACL to the extent fair value is less than the amortized cost basis. Declines in fair value that have not been recorded through the ACL are recorded through other comprehensive income, net of applicable taxes. In assessing whether an impairment is credit loss related, the Company compares the present value of cash flows expected to be collected to the security's amortized cost basis. If the present value of cash flows expected to be collected is less than the amortized cost basis of the security, a credit loss exists and an ACL is recorded. The Company discounts expected cash flows at the effective interest rate implicit in the security at the purchase date, adjusted for expected prepayments. For floating rate securities, the Company uses the floating rate as it changes over the life of the security. In developing estimates about cash flows expected to be collected and determining whether a credit loss exists, the Company considers information about past events, current conditions and reasonable and supportable forecasts. Factors and information that the Company uses in making its assessments include, but are not necessarily limited to, the following: • The extent to which fair value is less than amortized cost; • Adverse conditions specifically related to the security, an industry or geographic area; • Changes in the financial condition of the issuer or underlying loan obligors; • The payment structure and remaining payment terms of the security, including levels of subordination or over-collateralization; • Failure of the issuer to make scheduled payments; • Changes in credit ratings; • Relevant market data; • Estimated prepayments, defaults, and the value and performance of underlying collateral at the individual security level. The relative importance assigned to each of these factors varies depending on the facts and circumstances pertinent to the individual security being evaluated. Timely payment of principal and interest on securities issued by the U.S. Government, U.S. government agencies and U.S. government sponsored entities is explicitly or implicitly guaranteed by the U. S. government. Therefore, the Company expects to recover the amortized cost basis of these securities. If the Company intends to sell a security in an unrealized loss position, or it is more likely than not that the Company will be required to sell the security before recovery of its amortized cost basis, any allowance for credit losses will be written off and the amortized cost basis will be written down to the debt security’s fair value at the reporting date with any incremental impairment reported in earnings. AFS securities will be charged off to the extent that there is no reasonable expectation of recovery of amortized cost basis. AFS securities will be placed on non-accrual status if the Company does not reasonably expect to receive interest payments in the future and interest accrued will be reversed against interest income. Securities will be returned to accrual status only when collection of interest is reasonably assured. Loans The ACL is a valuation account that is deducted from the amortized cost basis of loans to present the net amount expected to be collected. The ACL is adjusted through the provision for credit losses to the amount of amortized cost basis not expected to be collected, or in the case of PCD loans, the amount of UPB not expected to be collected, at the balance sheet date. Amortized cost basis includes UPB, unamortized premiums or discounts and deferred fees and costs, net of amounts previously charged off. The measurement of expected credit losses encompasses information about historical events, current conditions and reasonable and supportable forecasts. Determining the amount of the ACL is complex and requires extensive judgment by management about matters that are inherently uncertain. Re-evaluation of the ACL estimate in future periods, in light of changes in composition and characteristics of the loan portfolio, changes in the reasonable and supportable forecast and other factors then prevailing may result in material changes in the amount of the ACL and credit loss expense in those future periods. Loans are charged off against the ACL in the period in which they are deemed uncollectible and recoveries are credited to the ACL when received. Expected recoveries on loans previously charged off and expected to be charged-off, not to exceed the aggregate of amounts previously charged-off and expected to be charged-off, are included in the ACL estimate. For loans secured by residential real estate, an assessment of collateral value is made at no later than 120 days delinquency; any outstanding loan balance in excess of fair value less cost to sell is charged off at no later than 180 days delinquency. Additionally, any outstanding balance in excess of fair value of collateral less cost to sell is charged off (i) within 60 days of receipt of notification of filing from the bankruptcy court, (ii) within 60 days of determination of loss if all borrowers are deceased or (iii) within 90 days of discovery of fraudulent activity. Other consumer loans are typically charged off at 120 days delinquency. Commercial loans are charged off when, in management's judgment, they are considered to be uncollectible. Expected credit losses are estimated on a collective basis for groups of loans that share similar risk characteristics. Factors that may be considered in aggregating loans for this purpose include but are not necessarily limited to, product or collateral type, industry, geography, internal risk rating, credit characteristics such as credit scores or collateral values, and historical or expected credit loss patterns. For loans that do not share similar risk characteristics with other loans such as collateral dependent loans and TDRs, expected credit losses are estimated on an individual basis. Expected credit losses are estimated over the contractual terms of the loans, adjusted for expected prepayments. Expected prepayments for commercial loans are generally estimated based on the Company's historical experience. For residential loans, expected prepayments are estimated using a model that incorporates industry prepayment data, calibrated to reflect the Company's experience. The contractual term excludes expected extensions, renewals, and modifications unless either of the following applies: management has a reasonable expectation at the reporting date that a TDR will be executed with an individual borrower or the extension or renewal options are included in the original or modified contract at the reporting date and are not unconditionally cancellable by the Company. For the substantial majority of portfolio segments and subsegments, including residential loans other than government insured loans, and most commercial and commercial real estate loans, expected losses are estimated using econometric models. The models employ a factor based methodology, leveraging data sets containing extensive historical loss and recovery information by industry, geography, product type, collateral type and obligor characteristics, to estimate PD and LGD. Measures of PD for commercial loans incorporate current conditions through market cycle or credit cycle adjustments. For residential loans, the models consider FICO and adjusted LTVs. PDs and LGDs are then conditioned on the reasonable and supportable economic forecast. Projected PDs and LGDs, determined based on pool level characteristics, are applied to estimated exposure at default, considering the contractual term and payment structure of loans, adjusted for prepayments, to generate estimates of expected loss. For criticized or classified loans, PDs are adjusted to benchmark PDs established for each risk rating if the most current financial information available is deemed not to be reflective of the borrowers' current financial condition. The ACL estimate incorporates a reasonable and supportable economic forecast through the use of externally developed macroeconomic scenarios applied in the models. A single economic scenario or a probability weighted blend of economic scenarios may be used. The models ingest numerous national, regional and MSA level variables and data points. Commercial Real Estate Model Variables with the most significant impact on the commercial real estate model include unemployment at both national and regional levels, the CRE property forecast by property type and sub-market, 10 year treasury yield, Baa corporate yield and real GDP growth, at the national level. Increases in unemployment and yields within the commercial real estate model result in increases in the ACL. Increases in real GDP growth and improvements in the CRE property forecasts reduce the reserve. Commercial Model Variables with the most significant impact on the commercial model include a stock market volatility index, the S&P 500 index, unemployment, at both national and regional levels, and a variety of interest rates and spreads. Increases in the unemployment rate, the stock market volatility index, and the Baa corporate yield increase the reserve, while increases in real GDP growth reduce the reserve. Residential Model Variables with the most significant impact on the residential model include HPI and unemployment at regional levels, real GDP growth, and a 30 year mortgage rate. Increases in the unemployment rate and the 30-year mortgage rate increase the reserve, while increases in real GDP growth and HPI reduce the reserve. The length of the reasonable and supportable forecast period is evaluated at each reporting period and adjusted if deemed necessary. Currently, the Company uses a 2-year reasonable and supportable forecast period in estimating the ACL. After the reasonable and supportable forecast periods, the models effectively revert to long-term mean losses on a straight-line basis over 12 months. For certain less material portfolios including loans and leases to state and local government entities originated by Pinnacle, small balance commercial loans and consumer loans, the WARM method is used to estimate expected credit losses. Loss rates are applied to the exposure at default, after factoring in amortization and expected prepayments. For the Pinnacle portfolio, historical loss information is based on municipal historical default and recovery data, segmented by credit rating. For small balance commercial loans, historical loss information is based on the Company's historical loss experience over a five year period. For consumer loans, historical loss information is based on peer data; this portfolio subsegment is not significant. All loss estimates are conditioned as applicable on changes in current conditions and the reasonable and supportable economic forecast. Expected credit losses for the funded portion of mortgage warehouse lines of credit are estimated based primarily on the Company's historical loss experience, conditioned as applicable on changes in current conditions and the reasonable and supportable economic forecast. Generally, given the nature of these loans, losses would be expected to manifest within a very short time period after origination. The Company expects to collect the amortized cost basis of government insured residential loans and PPP loans due to the nature of the government guarantee, so the ACL is zero for these loans. Qualitative factors Quantitative models have certain inherent limitations with respect to estimating expected losses. These limitations may be more prevalent in times of rapidly changing economic conditions and forecasts. Qualitative adjustments are made to the ACL when, based on management’s judgment, there are factors impacting expected credit losses not taken into account by the quantitative calculations. Potential qualitative adjustments are categorized as follows: • Economic factors, including material uncertainties, trends and developments that, in management's judgment, may not have been considered in the reasonable and supportable economic forecast; • Credit policy and staffing, including the nature and level of policy and procedural exceptions or changes in credit policy not reflected in quantitative results, changes in the quality of underwriting and portfolio management and staff and issues identified by credit review, internal audit or regulators that may not be reflected in quantitative results; • Concentrations, considering whether the quantitative estimate adequately accounts for concentration risk in the portfolio; • Model imprecision and model validation findings; and • Other factors not adequately considered in the quantitative estimate or other qualitative categories identified by management that may materially impact the amount of expected credit losses. Collateral dependent loans Collateral dependent loans are those for which the borrower is experiencing financial difficulty and repayment is expected to be provided substantially through the operation or sale of the collateral. These loans do not typically share similar risk characteristics with other loans and expected credit losses are evaluated on an individual basis. Loans evaluated individually are not included in the collective evaluation. Estimates of expected credit losses for collateral dependent loans, whether or not foreclosure is probable, are based on the fair value of the collateral, adjusted for selling costs when repayment depends on sale of the collateral. Due to immateriality, expected credit losses for collateral dependent commercial relationships with committed balances less than $1.0 million may be estimated collectively. Troubled debt restructurings For TDRs or loans for which there is a reasonable expectation that a TDR will be executed that are not collateral dependent, the credit loss estimate is determined by comparing the net present value of expected cash flows, discounted at the loan’s original effective interest rate, to the amortized cost basis of the loan. Off-balance sheet credit exposures Expected credit losses related to off-balance sheet credit exposures are estimated over the contractual period for which the Company is exposed to credit risk via a contractual obligation to extend credit, unless that obligation is unconditionally cancellable by the Company. Expected credit losses are estimated using essentially the same methodologies employed to estimate expected credit losses on the amortized cost basis of loans, taking into consideration the likelihood and amount of additional amounts expected to be funded over the terms of the commitments. The liability for credit losses on off-balance sheet credit exposures is presented within other liabilities on the consolidated balance sheets, distinct from the ACL. Adjustments to the liability are included in the provision for credit losses.
Accrued Interest Receivable [Policy Text Block]	Accrued Interest Receivable The Company has elected to present accrued interest receivable separate from the amortized cost basis of financial assets carried at amortized cost. The Company excludes accrued interest receivable balances from tabular disclosures about financial assets carried at amortized cost. The Company generally does not estimate an ACL on accrued interest receivable balances since uncollectible accrued interest is timely written off in accordance with the Company's accounting policies for non-accrual loans. Under unusual circumstances, such as those presented by deferrals granted due to the COVID-19 pandemic, the Company evaluates whether its non-accrual policies continue to consistently provide for timely reversal of accrued interest receivable. If considered necessary, the Company records an allowance for uncollectible accrued interest receivable, determined using essentially the same methodologies used to estimate the ACL on the amortized cost basis of the related loans. The allowance is deducted from accrued interest receivable and presented within other assets on the consolidated balance sheets, distinct from the ACL. Changes in the ACL related to accrued interest receivable are included in the provision for credit losses.
Leases, Policy	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.
Bank Owned Life Insurance	Bank Owned Life Insurance Bank owned life insurance is carried at cash surrender value. Changes in cash surrender value are recorded in non-interest income.
Lessor, Leases	Operating Lease Equipment Operating lease equipment is carried at cost less accumulated depreciation and is depreciated to estimated residual value using the straight-line method over the lease term. Estimated residual values are re-evaluated at least annually, based primarily on current residual value appraisals. Rental revenue is recognized on a straight-line basis over the contractual term of the lease.
Goodwill and Intangible Assets, Policy	Goodwill Goodwill represents the excess of consideration transferred in business combinations over the fair value of net tangible and identifiable intangible assets acquired. Goodwill is not amortized, but is tested for impairment annually or more frequently if events or circumstances indicate that impairment may have occurred. The Company performs its annual goodwill impairment test in the third fiscal quarter. The Company has a single reporting unit. When assessing goodwill for impairment, the Company may elect to perform a qualitative assessment to determine if a quantitative impairment test is necessary. If a qualitative assessment is not performed, or if the qualitative assessment indicates it is likely that the fair value of a reporting unit is less than its carrying amount, a quantitative test is performed. The quantitative impairment test compares the estimated fair value of the reporting unit to its carrying amount. If the fair value of the reporting unit exceeds its carrying amount, no impairment is indicated. If the fair value of the reporting unit is less than its carrying amount, impairment of goodwill is measured as the excess of the carrying amount over fair value.
Financing Receivable, Held-for-investment, Foreclosed Asset [Policy Text Block]	OREO and Repossessed Assets OREO and repossessed assets consists of real estate assets acquired through, or in lieu of, loan foreclosure and personal property acquired through repossession. Such assets are included in other assets in the accompanying consolidated balance sheets. These assets are held for sale and are initially recorded at estimated fair value less costs to sell, establishing a new cost basis. Subsequent to acquisition, periodic valuations are performed and the assets are carried at the lower of the carrying amount at the date of acquisition or estimated fair value less cost to sell. Significant property improvements are capitalized to the extent that the resulting carrying value does not exceed fair value less cost to sell. Legal fees, maintenance, taxes, insurance and other direct costs of holding and maintaining these assets are expensed as incurred.
Property, Plant and Equipment, Policy	Premises and Equipment Premises and equipment are carried at cost less accumulated depreciation and amortization and are included in other assets in the accompanying consolidated balance sheets. The Company measures assets held for sale at the lower of carrying amount or estimated fair value. Depreciation is calculated using the straight-line method over the estimated useful lives of the assets. The lives of improvements to existing buildings are based on the lesser of the estimated remaining lives of the buildings or the estimated useful lives of the improvements. Leasehold improvements are amortized over the shorter of the expected terms of the leases at inception, considering options to extend that are reasonably assured, or their useful lives. The estimated useful lives of premises and equipment are as follows: • buildings and improvements - 10 to 30 years; • leasehold improvements - 5 to 20 years; • furniture, fixtures and equipment - 5 to 7 years; and • computer equipment - 3 to 5 years.
Software and CCA	Software and CCA Software and CCA are carried at cost less accumulated depreciation and amortization and are included in other assets in the accompanying consolidated balance sheets. Depreciation and amortization are calculated using the straight-line method over the estimated useful lives of the assets, which for CCA is based on the term of the associated hosting arrangements plus any reasonably certain renewals. Direct costs associated with developing or obtaining and implementing internal use software and hosting arrangements that are service contracts incurred during the application development stage are capitalized. The estimated useful lives of software, software licensing rights and CCA implementation costs range from 3 to 5 years.
Transfers and Servicing of Financial Assets, Transfers of Financial Assets, Financings, Policy	Loan Servicing Rights Loan servicing rights relate to the portion of SBA and USDA loans sold in the secondary market and are measured at fair value, with changes in fair value subsequent to acquisition recognized in earnings. Loan servicing rights are included in other assets in the accompanying consolidated balance sheets. Servicing fee income is recorded net of changes in fair value in other non-interest income. Neither the loan servicing rights nor related income have had a material impact on the Company's financial statements to date.
Investments in Affordable Housing Limited Partnerships	Investments in Affordable Housing Limited Partnerships The Company has acquired investments in limited partnerships that manage or invest in qualified affordable housing projects and provide the Company with low-income housing tax credits and other tax benefits. These investments are included in other assets in the accompanying consolidated balance sheets. The Company accounts for investments in qualified affordable housing projects using the proportional amortization method if certain criteria are met. Under the proportional amortization method, the initial cost of the investment is amortized in proportion to the tax credits and other tax benefits received and the amortization is recognized in the income statement as a component of income tax expense.
Income Tax, Policy	Income Taxes The Company accounts for income taxes using the asset and liability method. Deferred tax assets and liabilities are determined based on differences between the financial reporting and tax bases of assets and liabilities using enacted tax rates in effect for periods in which the differences are expected to reverse. The effect of changes in tax rates on deferred tax assets and liabilities are recognized in income in the period that includes the enactment date. A valuation allowance is established for deferred tax assets when management determines that it is more likely than not that some portion or all of a deferred tax asset will not be realized. In making such determinations, the Company considers all available positive and negative evidence that may impact the realization of deferred tax assets. These considerations include the amount of taxable income generated in statutory carryback periods, future reversals of existing taxable temporary differences, projected future taxable income and available tax planning strategies. The Company recognizes tax benefits from uncertain tax positions when it is more likely than not that the related tax positions will be sustained upon examination, including resolutions of any related appeals or litigation processes, based on the technical merits of the tax positions. An uncertain tax position is a position taken in a previously filed tax return or a position expected to be taken in a future tax return that is not based on clear and unambiguous tax law. The Company measures tax benefits related to uncertain tax positions based on the largest benefit that has a greater than 50% likelihood of being realized upon settlement. If the initial assessment fails to result in recognition of a tax benefit, the Company subsequently recognizes a tax benefit if (i) there are changes in tax law or case law that raise the likelihood of prevailing on the technical merits of the position to more-likely-than-not, (ii) the statute of limitations expires, or (iii) there is a completion of an examination resulting in a settlement of that tax year or position with the appropriate agency. The Company recognizes interest and penalties related to uncertain tax positions, as well as interest income or expense related to tax settlements, in the provision for income taxes.
Share-based Payment Arrangement	Equity Based Compensation The Company periodically grants unvested or restricted shares of common stock and other share-based awards to key employees. For equity classified awards, compensation cost is measured based on the estimated fair value of the awards at the grant date and is recognized in earnings on a straight-line basis over the requisite service period for each award. Liability-classified awards are remeasured each reporting period at fair value until the award is settled, and compensation cost is recognized in earnings on a straight-line basis over the requisite service period for each award, adjusted for changes in fair value each reporting period. Compensation cost related to awards that embody performance conditions is recognized when it is probable that the performance conditions will be achieved. The number of awards expected to vest is estimated in determining the amount of compensation cost to be recognized related to share-based payment transactions.
Derivatives, Policy	Derivative Financial Instruments and Hedging Activities Interest rate derivative contracts The Company uses interest rate derivative contracts, such as swaps, caps, floors and collars, in the normal course of business to meet the financial needs of its customers and to manage exposure to changes in interest rates. Interest rate contracts are recorded as assets or liabilities in the consolidated balance sheets at fair value. Interest rate derivatives that are used as a risk management tool to hedge the Company's exposure to changes in interest rates have been designated as cash flow or fair value hedging instruments. The gain or loss resulting from changes in the fair value of interest rate swaps designated and qualifying as cash flow hedging instruments is initially reported as a component of other comprehensive income and subsequently reclassified into earnings in the same period in which the hedged transaction affects earnings. 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 the designated benchmark interest rates are recognized in earnings. The Company discontinues hedge accounting prospectively when it is determined that the derivative is no longer effective in offsetting changes in the cash flows or fair value of the hedged item, the derivative expires or is sold, terminated, or exercised, management determines that the designation of the derivative as a hedging instrument is no longer appropriate or, for a cash flow hedge, the occurrence of the forecasted transaction is no longer probable. When hedge accounting on a cash flow hedge is discontinued, any subsequent changes in fair value of the derivative are recognized in earnings. The cumulative unrealized gain or loss related to a discontinued cash flow hedge continues to be reported in AOCI and is subsequently reclassified into earnings in the same period in which the hedged transaction affects earnings, unless it is probable that the forecasted transaction will not occur by the end of the originally specified time period, in which case the cumulative unrealized gain or loss reported in AOCI is reclassified into earnings immediately. When hedge accounting on a fair value hedge is discontinued, adjustments to the carrying amount of the hedged item due to changes in fair value are also discontinued. Cash flows from derivative financial instruments that are accounted for as hedges, including daily settlements of centrally cleared derivatives with the CME, are classified as operating cash flows. Changes in the fair value of interest rate contracts not designated as, or not qualifying as, hedging instruments are recognized currently in earnings.
Transfers and Servicing of Financial Assets, Servicing of Financial Assets, Policy	Transfers of Financial Assets Transfers of financial assets are accounted for as sales when control over the assets has been surrendered. A gain or loss is recognized in earnings upon completion of the sale based on the difference between the sales proceeds and the carrying value of the assets. Control over the transferred assets is deemed to have been surrendered when: (i) the assets have been legally isolated from the Company, (ii) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (iii) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity or the ability to unilaterally cause the holder to return specific assets.
Earnings Per Share, Policy	Earnings per Common Share Basic earnings per common share is calculated by dividing income allocated to common stockholders for basic earnings per common share by the weighted average number of common shares outstanding for the period, reduced by average unvested stock awards. Unvested stock awards with non-forfeitable rights to dividends, whether paid or unpaid, and stand-alone dividend participation rights are considered participating securities and are included in the computation of basic earnings per common share using the two class method whereby net income is allocated between common stock and participating securities. In periods of a net loss, no allocation is made to participating securities as they are not contractually required to fund net losses. Diluted earnings per common share is computed by dividing income allocated to common stockholders for basic earnings per common share, adjusted for earnings reallocated from participating securities, by the weighted average number of common shares outstanding for the period increased for the dilutive effect of unexercised stock options and unvested stock awards using the treasury stock method. Contingently issuable shares are included in the calculation of earnings per common share as if the end of the respective period was the end of the contingency period.
Revenue	Revenue From Contracts with Customers Revenue from contracts with customers within the scope of Topic 606 " Revenue from Contracts with Customers ", is recognized in an amount that reflects the consideration the Company expects to be entitled to receive in exchange for those goods or services as the related performance obligations are satisfied. The majority of our revenues, including revenues from loans, leases, investment securities, derivative instruments and letters of credit and from transfers and servicing of financial assets, are excluded from the scope of Topic 606. Deposit service charges and fees is the most significant category of revenue within the scope of the standard. These service charges and fees consist primarily of monthly maintenance fees and other transaction based fees. Revenue is recognized when our performance obligations are complete, generally monthly for account maintenance fees or when a transaction, such as a wire transfer, is completed. Payment is typically received at the time the performance obligation is satisfied. The aggregate amount of revenue that is within the scope of Topic 606 from sources other than deposit service charges and fees is not material.
New Accounting Pronouncements, Policy [Policy Text Block]	New Accounting Pronouncements Adopted in 2021 ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. This ASU simplified the accounting for income taxes by removing certain exceptions stipulated in ASC 740 and making some other targeted changes to the accounting for income taxes. The Company adopted this ASU on January 1, 2021 with no material impact on the Company’s consolidated financial position, results of operations, and cash flows. ASU No. 2021-01, Reference Rate Reform (Topic 848) . This ASU clarified that certain optional expedients and exceptions provided for in ASU No. 2020-04 for applying GAAP to contract modifications and hedging relationships apply to derivatives that are affected by the discounting transition. The amendments in this ASU are elective and apply to all entities that have derivative instruments that use an interest rate for margining, discounting, or contract price alignment that is modified as a result of reference rate reform. This ASU is effective immediately for all entities and it can be applied on a retrospective basis as of any date from the beginning of an interim period that includes or is subsequent to March 22, 2020, or on a prospective basis beginning on January 7, 2021. The Company elected to adopt this ASU on a retrospective basis. To date, the impact of adoption of this ASU on the Company's consolidated financial position, results of operations, and cash flows has not been material.
Accounting Standards Update and Change in Accounting Principle	Accounting Pronouncements Not Yet Adopted ASU No. 2020-06, Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity’s Own Equity (Subtopic 815-40) . This ASU simplifies the accounting for convertible debt and convertible preferred stock by reducing the number of accounting models for these instruments, resulting in fewer embedded conversion features being separately recognized from the host contract. Additionally, this ASU revises the criteria for determining whether contracts in an entity's own equity meet the scope exception from derivative accounting, which will change the population of contracts that are recognized as assets or liabilities. The amendments in this ASU also revise certain aspects of the guidance on calculating earnings per share with respect to convertible instruments and instruments that may be settled in the entity's own shares. This ASU is effective for the Company for interim and annual periods in fiscal years beginning after December 15, 2021. The impact of adoption of this ASU on the Company's consolidated financial position, results of operations, and cash flows is not expected to be material.

The amortized cost basis of residential PCD loans and the related amount of non-credit discount was $65 million and $60 million, respectively at December 31, 2021 and $118 million and $115 million, respectively at December 31, 2020. The ACL related to PCD residential loans was $0.5 million and $2.8 million at December 31, 2021 and 2020, respectively. During the years ended December 31, 2021, 2020, and 2019, the Company purchased residential and other consumer loans totaling $4.8 billion, $3.2 billion and $2.2 billion, respectively. Purchases for the years ended December 31, 2021, 2020, and 2019 included $1.6 billion, $1.4 billion and $844 million, respectively, of government insured residential loans. At December 31, 2021 and 2020, the Company had pledged loans with a carrying value of approximately $10.6 billion and $9.6 billion, respectively, as security for FHLB advances and Federal Reserve discount window capacity. At December 31, 2021 and 2020, accrued interest receivable on loans, net of related ACL at December 31, 2020, totaled $98 million and $99 million, respectively, and is included in other assets in the accompanying consolidated balance sheets. The amount of interest income reversed on non-accrual loans was not material for the years ended December 31, 2021 and 2020.
Allowance for Credit Losses on Financing Receivables	Activity in the allowance for credit losses is summarized below. The balances for the year ended December 31, 2019 represent the allowance for loan and leases losses, estimated using an incurred loss methodology. The ACL at December 31, 2021 and 2020 was determined using the CECL methodology, utilizing a 2-year reasonable and supportable forecast period based on a single third-party provided economic scenario (in thousands): Years Ended December 31, 2021 2020 2019 Residential and Other Consumer Commercial Total Residential and Other Consumer Commercial Total Residential and Other Consumer Commercial Total Beginning balance $ 18,719 $ 238,604 $ 257,323 $ 11,154 $ 97,517 $ 108,671 $ 10,788 $ 99,143 $ 109,931 Impact of adoption of ASU 2016-13 N/A N/A N/A 8,098 19,207 27,305 N/A N/A N/A Balance after adoption of ASU 2016-13 N/A N/A N/A 19,252 116,724 135,976 N/A N/A N/A Provision (recovery) (9,241) (55,215) (64,456) (556) 182,895 182,339 154 8,750 8,904 Charge-offs (304) (70,946) (71,250) (31) (69,571) (69,602) — (17,541) (17,541) Recoveries 13 4,827 4,840 54 8,556 8,610 212 7,165 7,377 Ending balance $ 9,187 $ 117,270 $ 126,457 $ 18,719 $ 238,604 $ 257,323 $ 11,154 $ 97,517 $ 108,671 The decrease in the ACL from December 31, 2020 to December 31, 2021 resulted from charge-offs and the recovery of credit losses recorded during the year ended December 31, 2021. The most significant factor contributing to the recovery of provision for 2021 was improvements in economic conditions and the economic forecast. The increase in the ACL from January 1, 2020, the date of initial adoption of ASU 2016-13, to December 31, 2020 was reflective of the impact of the COVID-19 pandemic on current economic conditions, the economic forecast and on individual borrowers and portfolio sub-segments.

Financing Receivable Credit Quality Indicators	FICO scores are generally updated at least annually, and were most recently updated in the third quarter of 2021. 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 and wages, as well as residential property values. 1-4 Single Family Residential credit exposure, excluding government insured residential loans, based on delinquency status: December 31, 2021 Amortized Cost By Origination Year 2021 2020 2019 2018 2017 Prior Total Current $ 2,884,761 $ 1,062,348 $ 395,453 $ 224,175 $ 342,414 $ 1,352,844 $ 6,261,995 30 - 59 Days Past Due 32,307 2,705 5,482 1,942 5,831 4,825 53,092 60 - 89 Days Past Due 605 — 1,750 1,988 — 1,307 5,650 90 Days or More Past Due 1,407 — 609 5,100 1,064 9,308 17,488 $ 2,919,080 $ 1,065,053 $ 403,294 $ 233,205 $ 349,309 $ 1,368,284 $ 6,338,225 December 31, 2020 Amortized Cost By Origination Year 2020 2019 2018 2017 2016 Prior Total Current $ 1,092,183 $ 645,993 $ 374,838 $ 611,377 $ 740,749 $ 1,392,192 $ 4,857,332 30 - 59 Days Past Due 17,826 5,741 2,564 927 2,913 18,880 48,851 60 - 89 Days Past Due 111 145 435 — 2,825 3,973 7,489 90 Days or More Past Due — 807 1,762 53 1,027 5,515 9,164 $ 1,110,120 $ 652,686 $ 379,599 $ 612,357 $ 747,514 $ 1,420,560 $ 4,922,836 1-4 Single Family Residential credit exposure, excluding government insured residential loans, based on LTV: December 31, 2021 Amortized Cost By Origination Year LTV 2021 2020 2019 2018 2017 Prior Total Less than 61% $ 1,222,510 $ 399,512 $ 89,078 $ 54,301 $ 111,540 $ 476,170 $ 2,353,111 61% - 70% 791,935 269,739 92,282 59,425 66,641 343,654 1,623,676 71% - 80% 899,400 395,726 212,649 111,276 145,413 518,817 2,283,281 More than 80% 5,235 76 9,285 8,203 25,715 29,643 78,157 $ 2,919,080 $ 1,065,053 $ 403,294 $ 233,205 $ 349,309 $ 1,368,284 $ 6,338,225 December 31, 2020 Amortized Cost By Origination Year LTV 2020 2019 2018 2017 2016 Prior Total Less than 61% $ 395,977 $ 143,273 $ 82,199 $ 174,223 $ 286,092 $ 487,487 $ 1,569,251 61% - 70 % 298,941 151,633 92,928 119,381 184,119 341,159 1,188,161 71% - 80% 413,003 344,998 181,852 271,605 258,931 565,781 2,036,170 More than 80% 2,199 12,782 22,620 47,148 18,372 26,133 129,254 $ 1,110,120 $ 652,686 $ 379,599 $ 612,357 $ 747,514 $ 1,420,560 $ 4,922,836 1-4 Single Family Residential credit exposure, excluding government insured residential loans, based on FICO score: December 31, 2021 Amortized Cost By Origination Year FICO 2021 2020 2019 2018 2017 Prior Total 760 or greater $ 2,230,259 $ 803,026 $ 245,942 $ 125,713 $ 254,750 $ 937,285 $ 4,596,975 720 - 759 562,763 194,068 91,276 53,576 54,080 219,561 1,175,324 719 or less 126,058 67,959 66,076 53,916 40,479 211,438 565,926 $ 2,919,080 $ 1,065,053 $ 403,294 $ 233,205 $ 349,309 $ 1,368,284 $ 6,338,225 December 31, 2020 Amortized Cost By Origination Year FICO 2020 2019 2018 2017 2016 Prior Total 760 or greater $ 843,199 $ 435,582 $ 225,292 $ 451,304 $ 549,119 $ 956,254 $ 3,460,750 720 - 759 223,831 128,875 84,602 102,859 130,592 256,703 927,462 719 or less 43,090 88,229 69,705 58,194 67,803 207,603 534,624 $ 1,110,120 $ 652,686 $ 379,599 $ 612,357 $ 747,514 $ 1,420,560 $ 4,922,836 Credit quality indicators for commercial loans Factors that impact risk inherent in commercial portfolio segments include but are not limited to levels of economic activity, health of the national and regional economy, industry trends, patterns of and trends in customer behavior that influence demand for our borrowers' products and services, and commercial real estate values. Internal risk ratings are considered the most meaningful indicator of credit quality for commercial loans. Internal risk ratings are generally indicative of the likelihood that a borrower will default, are a key factor 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. Loans exhibiting potential credit weaknesses that deserve management’s close attention and that could result in deterioration of repayment prospects at some future date if not checked or corrected 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 from current operations, 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.

Banking and Thrift, Other Disclosures [Abstract]
Regulatory Capital Requirements under Banking Regulations [Text Block]	Note 13 Regulatory Requirements and Restrictions The Company and the Bank are subject to various regulatory capital requirements administered by Federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company's financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and the Bank must meet specific capital guidelines that involve quantitative measures of assets, liabilities and certain off-balance-sheet items calculated pursuant to regulation. The capital amounts and classification also are subject to qualitative judgments by the regulators about components, risk weightings and other factors. Banking regulations identify five capital categories for insured depository institutions: well-capitalized, adequately capitalized, undercapitalized, significantly undercapitalized and critically undercapitalized. As of December 31, 2021 and 2020, all capital ratios of the Company and the Bank exceeded the "well capitalized" levels under the regulatory framework for prompt corrective action. Quantitative measures established by regulation to ensure capital adequacy require the Company and the Bank to maintain minimum amounts and ratios of total, common equity tier 1 and tier 1 capital (as defined in the regulations) to risk-weighted assets (as defined), and of tier 1 capital to average tangible assets (leverage ratio).

Upon the adoption of ASU 2016-13 effective January 1, 2020, the Company elected the option to temporarily delay the effects of CECL on regulatory capital for two years, followed by a three-year transition period. BankUnited is subject to various regulatory restrictions relating to the payment of dividends, including requirements to maintain capital at or above certain minimums, and to remain "well-capitalized" under the prompt corrective action regulations. The Company does not expect that any of these laws, regulations or policies will materially affect the ability of BankUnited to pay dividends in the foreseeable future.
