Fair Value Measurements

Note 9 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 rental 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. The Company has also established a quarterly process whereby prices provided by its primary pricing service for a sample of securities are validated. Any price discrepancies are resolved based on careful consideration of the assumptions and inputs employed by each of the pricing sources.

Servicing rights—Commercial servicing rights are valued using a discounted cash flow methodology incorporating contractually specified servicing fees and market based assumptions about prepayments, discount rates, default rates and costs of servicing. Prepayment and default assumptions are based on historical industry data for loans with similar characteristics. Assumptions about costs of servicing are based on market convention. Discount rates are based on rates of return implied by observed trades of underlying loans in the secondary market. 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 LIBOR swap rates and LIBOR forward yield curves. These fair value measurements are generally classified within level 2 of the fair value hierarchy.

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

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

Collateral dependent loans, 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.

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 (in thousands):

Derivatives and Hedging Activities

Note 6 Derivatives and Hedging Activities

The Company has entered into LIBOR-based interest rate swaps and caps designated as cash flow hedges with the objective of limiting the variability of interest payment cash flows. The Company has also entered into LIBOR-based 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 three and six months ended June 30, 2021 and 2020, 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 approximately zero at both June 30, 2021 and December 31, 2020.

During the three and six months ended June 30, 2021 and 2020, no derivative positions designated as cash flow hedges were discontinued and none of the gains and losses reported in AOCI were reclassified into earnings as a result of the discontinuance of cash flow hedges or because of the early extinguishment of debt. As of June 30, 2021, the amount of net loss expected to be reclassified from AOCI into earnings during the next twelve months was $38.9 million.

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

The difference between the amounts reported for interest rate swaps subject to master netting agreements and the total fair value of interest rate contract derivative financial instruments reported in the consolidated balance sheets is related to interest rate derivative contracts not subject to master netting agreements.

At June 30, 2021, the Company had pledged net financial collateral of $31.5 million as collateral for interest rate swaps in a liability position that are not centrally cleared. The amount of collateral required to be posted varies based on the settlement value of outstanding swaps and in some cases may include initial margin requirements.

The Company monitors its investment securities available for sale for credit loss impairment on an individual security basis. No securities were determined to be credit loss impaired during the three and six months ended June 30, 2021 and 2020. At June 30, 2021, the Company did not have an intent to sell securities that were in significant 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 June 30, 2021, 158 securities available for sale were in unrealized loss positions. The unrealized losses are primarily attributable to changes in interest rates and, in some cases, volatility in the financial markets since their purchase. The amount of impairment related to 51 of these securities was considered insignificant both individually and in the aggregate, totaling approximately $0.4 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 stressed economic scenarios 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 economic forecast scenario used for evaluation of impaired securities incorporates assumptions about voluntary prepayment rates, collateral defaults, delinquencies, severity, recovery lag and other relevant factors.

The decrease in the ACL from December 31, 2020 to June 30, 2021 related primarily to the recovery of credit losses recorded during the six months ended June 30, 2021. The most significant factor contributing to the recovery of provision was an improving economic forecast. The increase in the ACL from January 1, 2020, the date of initial adoption of ASU 2016-13, to June 30, 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 credit losses for the periods indicated (in thousands):

Financing Receivable Credit Quality Indicators

FICO scores are generally updated at least annually, and were most recently updated in the first 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.

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. Since the onset of the COVID-19 pandemic, risk ratings have been re-evaluated for a substantial portion of the commercial portfolio, with a focus on portfolio segments we identified for enhanced monitoring and loans that have been modified or for which we granted temporary payment deferrals. 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.

Income Taxes	6 Months Ended
Income Taxes	Jun. 30, 2020
Income Tax Disclosure [Abstract]
Income Taxes	Note 5 Income Taxes The Company’s effective income tax rate was 25.8% and 25.3% for the three and six months ended June 30, 2021, respectively and 21.0% and 19.3% for the three and six months ended June 30, 2020, respectively. The effective income tax rates differed from the statutory federal income tax rate of 21% for the three and six months ended June 30, 2021 due primarily to the impact of state income taxes, partially offset by the benefit of income not subject to federal tax. These factors were largely offsetting for the 2020 periods, when the effective tax rate did not differ materially from the Federal statutory rate of 21%. During the three and six months ended June 30, 2020, income not subject to tax was a larger percentage of pre-tax income when compared to the same periods in 2021.

- Definition

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

Unvested share awards

A summary of activity related to unvested share awards follows for the periods indicated:


	Number of Share Awards	Weighted Average Grant Date Fair Value
Unvested share awards outstanding, December 31, 2020	1,161,835	$	33.32
Granted	559,180	42.17
Vested	(460,269)	34.01
Canceled or forfeited	(48,684)	35.19
Unvested share awards outstanding, June 30, 2021	1,212,062	$	37.07

Unvested share awards outstanding, December 31, 2019	1,050,455	$	38.24
Granted	644,300	29.73
Vested	(455,260)	39.15
Canceled or forfeited	(33,137)	36.21
Unvested share awards outstanding, June 30, 2020	1,206,358	$	33.41

Unvested share awards are generally valued at the closing price of the Company's common stock on the date of grant. All shares granted prior to 2019 vest in equal annual installments over a period of three years from the date of grant. All shares granted in 2019 and later to Company employees vest in equal annual installments over a period of four years from the date of grant. Shares granted to the Company's Board of Directors 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):


	Six Months Ended June 30,
	2021		2020
Closing price on date of grant	$42.01 - $47.52		$13.99 - $30.90
Aggregate grant date fair value of shares vesting	$	15,652	$	17,824

The total unrecognized compensation cost of $34.5 million for all unvested share awards outstanding at June 30, 2021 will be recognized over a weighted average remaining period of 2.94 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 generally vest on December 31st in equal tranches over three years for grants prior to 2019, and over four years for awards issued in 2019 and after. PSUs are initially granted based on a target value. The number 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, 2020	156,555	179,793
Granted	63,814	63,814

Unvested executive share-based awards outstanding, June 30, 2021	220,369	243,607

Unvested executive share-based awards outstanding, December 31, 2019	112,116	125,088
Granted	106,731	106,731

Unvested executive share-based awards outstanding, June 30, 2020	218,847	231,819

The total liability for the share units was $6.8 million at June 30, 2021. The total unrecognized compensation cost of $13.0 million for these share units at June 30, 2021 will be recognized over a weighted average remaining period of 2.22 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 related to performance periods prior to 2019 vest over three years and awards related to the 2019 and subsequent performance periods 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. The accrued liability and unrecognized compensation cost are based on management's current estimate of the likely outcome of the performance criteria established in the incentive arrangements and may differ from actual results.

Option Awards

A summary of activity related to stock option awards for the six months ended June 30, 2021 and 2020 follows:


	Number of Option Awards	Weighted Average Exercise Price
Option awards outstanding, December 31, 2020	1,569	$	15.94

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.

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 clarifies 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. The Company elected to adopt this ASU on a retrospective basis. The impact of adoption of this ASU on the Company's consolidated financial position, results of operations, and cash flows was not 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 Company has not finalized its evaluation of the impact of adoption on its consolidated financial position, results of operations, and cash flows, but the impact is not currently expected to be material.

- Definition

The entire disclosure for change in accounting principle. Includes, but is not limited to, nature, reason, and method of adopting amendment to accounting standards or other change in accounting principle.

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 first 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.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Significant Accounting Policies [Text Block]	Basis of Presentation and Summary of Significant Accounting Policies BankUnited, Inc. is a national bank holding company with one wholly-owned subsidiary, BankUnited, collectively, the Company. BankUnited, a national banking association headquartered in Miami Lakes, Florida, provides a full range of banking and related services to individual and corporate customers through 65 banking centers located in 13 Florida counties and 4 banking centers located in the New York metropolitan area at June 30, 2021. The Bank also offers certain commercial lending and deposit products through national platforms. The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X of the SEC. Accordingly, these do not include all of the information and footnotes required for a fair presentation of financial position, results of operations and cash flows in conformity with GAAP and should be read in conjunction with the Company’s consolidated financial statements and the notes thereto appearing in BKU’s Annual Report on Form 10-K for the year ended December 31, 2020 filed with the SEC. In the opinion of management, all adjustments, consisting of normal recurring adjustments, considered necessary for a fair presentation have been included. Operating results for the three and six months ended June 30, 2021 are not necessarily indicative of the results that may be expected in future periods. Accounting Estimates In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, and expenses and disclosures of contingent assets and liabilities. Actual results could differ significantly from these estimates. The most significant estimate impacting the Company's consolidated financial statements is the ACL. New Accounting Pronouncements Adopted During the Six Months Ended June 30, 2021 ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. This ASU simplifies 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 clarifies 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. The Company elected to adopt this ASU on a retrospective basis. The impact of adoption of this ASU on the Company's consolidated financial position, results of operations, and cash flows was not material. 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 Company has not finalized its evaluation of the impact of adoption on its consolidated financial position, results of operations, and cash flows, but the impact is not currently expected to be material.

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingencies

Note 10 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.

Commercial and standby letters of credit

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

Total lending related commitments outstanding at June 30, 2021 were as follows (in thousands):


Commitments to fund loans	$	622,579

Unfunded commitments under lines of credit	3,747,497
Commercial and standby letters of credit	95,034
	$	4,465,110

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.
