PART I – FINANCIAL INFORMATION

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis provides information that management believes is necessary to understand the Company's financial condition, results of operations, and cash flows for the three and six months ended June 30, 2023, as compared to 2022. This information should be read in conjunction with the Condensed Consolidated Financial Statements, and accompanying Notes thereto, contained in Part I - Item 1. Financial Statements of this report, and the Consolidated Financial Statements, and accompanying Notes thereto, contained in Part II - Item 8. Financial Statements and Supplementary Data of the Company's Annual Report on Form 10-K for the year ended December 31, 2022, which was filed with the SEC on
March 10, 2023. The Company's financial condition, results of operations, and cash flows for the three and six months ended June 30, 2023, are not necessarily indicative of future results that may be attained for the entire year or other interim periods.

Executive Overview

Nature of Operations

Webster Financial Corporation is a bank holding company and financial holding company under the BHC Act, incorporated under the laws of Delaware in 1986, and headquartered in Stamford, Connecticut. Webster Bank, along with its HSA Bank division, is a leading commercial bank in the Northeast that delivers a wide range of digital and traditional financial solutions to businesses, individuals, families, and partners across its three differentiated lines of business: Commercial Banking, HSA Bank, and Consumer Banking. While its core footprint spans from New York to Rhode Island and Massachusetts, certain businesses operate in extended geographies. HSA Bank is one of the largest providers of employee benefit solutions in the United States.

Recent Industry Developments

During the first quarter and into the second quarter of 2023, the banking industry experienced significant volatility with multiple high-profile bank failures and industry-wide concerns related to liquidity, deposit outflows, unrealized losses on securities, and eroding consumer confidence in the banking system. Despite these negative industry developments, the Company's total deposits at June 30, 2023, were $58.7 billion, representing a net $4.7 billion increase compared to its total deposits at December 31, 2022. The Holding Company's and the Bank's regulatory capital ratios at June 30, 2023, also remained in excess of the well-capitalized minimum as defined by capital adequacy guidelines and the regulatory framework for prompt corrective action.

Additional information regarding regulatory capital ratios can be found within Note 10: Regulatory Capital and Restrictions in the Notes to Condensed Consolidated Financial Statements contained in Part I - Item 1. Financial Statements.

interLINK Acquisition

On January 11, 2023, Webster acquired interLINK, a technology-enabled deposit management platform that administers over $9 billion of deposits from FDIC-insured cash sweep programs between banks and broker/dealers and clearing firms. The acquisition expanded the Company's core deposit funding sources and scalable liquidity and added another technology-enabled channel to its already differentiated, omnichannel deposit gathering capabilities. At June 30, 2023, interLINK provided the Company with an additional $4.3 billion of money market deposits.

Additional information regarding the acquisition of interLINK can be found within Note 2: Mergers and Acquisitions in the Notes to Condensed Consolidated Financial Statements contained in Part I - Item 1. Financial Statements.

Sterling Integration Update

On January 31, 2022, Webster completed its merger with Sterling. Significant progress on integration and conversion efforts was made throughout the year ended December 31, 2022, and the Company remains on track with key project milestones as of the second quarter of 2023, with a continued focus on business-as-usual operations.

The significant accomplishments achieved as of the end of the second quarter of 2023 were as follows:

1.The completion of final preparations for core conversion, including additional systems integrations and data validation exercises, user acceptance testing, financial center staffing and training plans, three mock conversions, employee training on new systems and processes, and customer communications;

2.The consolidation of bank routing numbers;

3.The connection of the ATM network to the go-forward environment; and

4.The implementation of a new call center interactive voice response system.

As originally planned, the core conversion of legacy Webster and legacy Sterling was completed in July 2023.

LIBOR Transition Update

The Company has a LIBOR transition plan in place that is commensurate with identified LIBOR transition risks and exposures, and is aligned with regulatory guidance and ARRC best practices. In preparation for the June 30, 2023 deadline for LIBOR cessations, management made significant progress on its LIBOR transition plan throughout the first and second quarters of 2023, addressing emerging issues and risks as they arose, while closely monitoring legislative and regulatory guidance associated with the LIBOR transition.

Effective July 1, 2023, LIBOR is no longer published for the overnight, one-month, three-month, six-month, and twelve-month settings. Alternative reference rates, including Federal fall-backs, which are to be used to various products, have been incorporated into the Company's LIBOR remediation plans. As of the date of this Quarterly Report on Form 10-Q, the Company remains focused on its remediation of the final remaining legacy LIBOR contracts, which are to transition to their applicable alternate reference rate at their first rate reset date after June 30, 2023. The Company also continues to monitor and respond to market developments, and regulatory and accounting requirements.

Non-GAAP Financial Measures

The non-GAAP financial measures identified in the preceding table provide both management and investors with information useful in understanding Webster's financial position, results of operations, the strength of its capital position, and overall business performance. These measures are used by management for internal planning and forecasting purposes, as well as by securities analysts, investors, and other interested parties to assess peer company operating performance. Management believes that this presentation, together with the accompanying reconciliations, provides investors with a more complete understanding of the factors and trends affecting the Company's business and allows investors to view its performance in a similar manner.

Tangible book value per common share represents stockholders’ equity less preferred stock and goodwill and other intangible assets (tangible common equity) divided by common shares outstanding at the end of the reporting period. The tangible common equity ratio represents tangible common equity divided by total assets less goodwill and other intangible assets (tangible assets). Both of these measures are used by management to evaluate the Company's capital position. The annualized return on average tangible common stockholders' equity is calculated using net income available to common stockholders, adjusted for the annualized tax-effected amortization of intangible assets, as a percentage of average tangible common equity. This measure is used by management to assess the Company's performance against its peer financial institutions. The efficiency ratio, which represents the costs expended to generate a dollar of revenue, is calculated excluding certain non-operational items in order to measure how well the Company is managing its recurring operating expenses.

These non-GAAP financial measures should not be considered a substitute for GAAP basis financial measures. Because
non-GAAP financial measures are not standardized, it may not be possible to compare these with other companies that present financial measures having the same or similar names.

The following tables reconcile non-GAAP financial measures to the most comparable financial measures defined by GAAP:

Net Interest Income

Net interest income is the Company's primary source of revenue, representing 86.7% and 88.0% of total revenues for the three and six months ended June 30, 2023, respectively, and 80.1% and 79.7% of total revenues for the three and six months ended June 30, 2022, respectively. Net interest income is the difference between interest income on interest-earning assets (i.e., loans and leases and investment securities) and interest expense on interest-bearing liabilities (i.e., deposits and borrowings), which are used to fund interest-earning assets and other activities. Net interest margin is calculated as the ratio of FTE net interest income to average interest-earning assets.

Net interest income, net interest margin, yields, and ratios on a FTE basis are considered non-GAAP financial measures, and are used by management to evaluate the comparability of the Company's revenue arising from both taxable and non-taxable sources. FTE adjustments are determined assuming a statutory federal income tax rate of 21%.

Net interest income and net interest margin are influenced by the volume and mix of interest-earning assets and interest-bearing liabilities, changes in interest rate levels, re-pricing frequencies, contractual maturities, prepayment behavior, and the use of interest rate derivative financial instruments. These factors are affected by changes in economic conditions, which impacts monetary policies, competition for loans and deposits, as well as the extent of interest lost on non-performing assets.

Comparison to Prior Year Quarter

Net interest income increased $97.1 million, or 20.0%, from $486.7 million for the three months ended June 30, 2022, to $583.8 million for the three months ended June 30, 2023. On a FTE basis, net interest income increased $102.7 million. Net interest margin increased 7 basis points from 3.28% for the three months ended June 30, 2022, to 3.35% for the three months ended June 30, 2023. These increases are primarily due to the higher interest rate environment.

Average total interest-earning assets increased $10.0 billion, or 16.7%, from $60.1 billion for the three months ended June 30, 2022, to $70.1 billion for the three months ended June 30, 2023, primarily due to increases of $7.1 billion, $3.0 billion, and $0.2 billion in average loans and leases, average interest-bearing deposits held at the FRB, and average FHLB and FRB stock, respectively, partially offset by a $0.4 billion decrease in average investment securities. The average yield on interest-earning assets increased 186 basis points from 3.46% for the three months ended June 30, 2022, to 5.32% for the three months ended June 30, 2023, primarily due to the higher interest rate environment, partially offset by a decrease in purchase accounting accretion on interest-earning assets that were acquired from Sterling.

At June 30, 2023, and 2022, the average total investment securities portfolio comprised 21.1% and 25.3% of total average interest-earning assets, respectively. The average yield on investment securities increased 77 basis points from 2.22% for the three months ended June 30, 2022, to 2.99% for the three months ended June 30, 2023, primarily due to the reinvestment of securities that either had matured or were sold at higher yields.

At June 30, 2023, and 2022, average total deposits comprised 88.0% and 94.2% of total average interest-bearing liabilities, respectively. The average rate on deposits increased 163 basis points from 0.09% for the three months ended June 30, 2022, to 1.72% for the three months ended June 30, 2023, primarily due to the higher interest rate environment and growth in higher costing deposit products. Higher cost time deposits as a percentage of average total interest-bearing deposits increased from 6.7% for the three months ended June 30, 2022, to 15.2% for the three months ended June 30, 2023, primarily due to a shift in customer preferences from lower rate checking and savings products into higher rate certificates of deposit products.

At June 30, 2023, and 2022, average securities sold under agreements to repurchase comprised 0.3% and 0.9% of total average interest-bearing liabilities, respectively. The average rate on securities sold under agreements to repurchase decreased 95 basis points from 1.06% for the three months ended June 30, 2022, to 0.11% for the three months ended June 30, 2023, primarily due to the Company's extinguishment of its two long-term structured repurchase agreements during the third quarter of 2022, which were contracted at a higher cost.

Provision for Credit Losses

Comparison to Prior Year Quarter

The provision for credit losses increased $19.3 million, or 157.3%, from $12.2 million for the three months ended June 30, 2022, to $31.5 million for the three months ended June 30, 2023. The increase is primarily due to the impact of the current macroeconomic environment on credit performance and organic loan growth, and losses recognized on commercial loan sales.

During the three months ended June 30, 2023, and 2022, total net charge-offs were $20.3 million and $9.6 million, respectively. The net increase of $10.7 million is primarily due to an increase in net charge-offs in the commercial real estate category, partially offset by a decrease in net charge-offs in the commercial non-mortgage category.

Comparison to Prior Year to Date

The provision for credit losses totaled $78.2 million and $201.1 million for the six months ended June 30, 2023, and 2022, respectively. The balance for the six months ended June 30, 2022, included the establishment of the initial ACL of $175.1 million for non-PCD loans and leases that were acquired from Sterling in the merger. Excluding this charge, the provision for credit losses increased $52.2 million, primarily due to the impact of the current macroeconomic environment on credit performance, organic loan growth, and losses recognized on commercial loan sales.

During the six months ended June 30, 2023, and 2022, total net charge-offs were $44.8 million and $18.5 million, respectively. The net increase of $26.3 million is primarily due to an increase in net charge-offs in the asset-based lending and commercial real estate categories, partially offset by a decrease in net charge-offs in the commercial non-mortgage category.

Additional information regarding the Company's provision for credit losses and ACL can be found under the sections captioned "Loans and Leases" through "Allowance for Credit Losses on Loans and Leases" contained elsewhere in this Part I - Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations.

During the six months ended June 30, 2023, the Company sold $418.8 million of U.S. Treasury notes, Corporate securities, and Municipal bonds and notes classified as available-for-sale for proceeds of $398.3 million, which resulted in $20.5 million of gross realized losses. The $16.8 million loss on sale of investment securities included in non-interest income represents the portion of the total charge that was not attributed to a decline in credit quality.

Income Taxes

Comparison to Prior Year Quarter

For the three months ended June 30, 2023, and 2022, the Company recognized income tax expense of $62.6 million and $54.8 million, respectively, reflecting effective tax rates of 21.0% and 23.1%, respectively.

The increase in income tax expense is due to a higher level of pre-tax income recognized during the three months ended June 30, 2023. The decrease in the effective tax rate is primarily due to an increase in tax-exempt interest income and tax credits and a decrease in state and local tax in 2023 as compared to 2022, partially offset by the effects of higher pre-tax income and non-deductible FDIC premiums in 2023 as compared to 2022.

Comparison to Prior Year to Date

For the six months ended June 30, 2023, and 2022, the Company recognized income tax expense of $128.5 million and $21.2 million, respectively, reflecting effective tax rates of 22.0% and 11.4%, respectively.

The lower income tax expense recognized for the six months ended June 30, 2022, reflected the recognition of the pre-tax loss and $33.6 million income tax benefit in the first quarter of 2022 associated with the Sterling merger, which resulted in decreases to both income tax expense and the effective tax rate for the six months ended June 30, 2022, making comparisons to the current period not meaningful.

Additional information regarding the Company's income taxes, including its DTAs, can be found within Note 9: Income Taxes in the Notes to Consolidated Financial Statements contained in Part II - Item 8. Financial Statements and Supplementary Data of the Company's Annual Report on Form 10-K for the year ended December 31, 2022.

Segment Reporting

The Company's operations are organized into three reportable segments that represent its primary businesses: Commercial Banking, HSA Bank, and Consumer Banking. These segments reflect how executive management responsibilities are assigned, how discrete financial information is evaluated, the type of customer served, and how products and services are provided. Segments are evaluated using PPNR. Certain Treasury activities, including the operations of interLINK, along with the amounts required to reconcile profitability metrics to those reported in accordance with GAAP, are included in the Corporate and Reconciling category. Additional information regarding the Company's reportable segments and its segment reporting methodology can be found within Note 16: Segment Reporting in the Notes to Condensed Consolidated Financial Statements contained in Part I - Item 1. Financial Statements.

The following is a description of the Company’s three reportable segments and their primary services:

Commercial Banking serves businesses with more than $2 million of revenue through its Commercial Real Estate and Equipment Finance, Middle Market, Business Banking, Asset-Based Lending and Commercial Services, Public Sector Finance, Mortgage Warehouse, Sponsor and Specialty Finance, Verticals and Support, Private Banking, and Treasury Management business units.

HSA Bank offers a comprehensive consumer-directed healthcare solution that includes HSAs, health reimbursement arrangements, flexible spending accounts, and commuter benefits. HSAs are used in conjunction with high deductible health plans in order to facilitate tax advantages for account holders with respect to health care spending and savings, in accordance with applicable laws. HSAs are distributed nationwide directly to employers and individual consumers, as well as through national and regional insurance carriers, benefit consultants, and financial advisors. HSA Bank deposits provide long duration, low-cost funding that is used to minimize the Company’s use of wholesale funding in support of its loan growth. In addition, non-interest revenue is generated predominantly through service fees and interchange income.

Consumer Banking serves individual customers and small businesses with less than $2 million of revenues by offering consumer deposits, residential mortgages, home equity lines, secured and unsecured loans, debit and credit card products, and investment services. Consumer Banking operates a distribution network consisting of 199 banking centers and 350 ATMs, a customer care center, and a full range of web and mobile-based banking services, primarily throughout southern New England and the New York Metro and Suburban markets.

Comparison to Prior Year Quarter

Commercial Banking's PPNR increased $25.1 million, or 9.0%, for the three months ended June 30, 2023, as compared to the three months ended June 30, 2022, due to an increase in net interest income, partially offset by a decrease in non-interest income and an increase in non-interest expense. The $50.2 million increase in net interest income is primarily due to organic loan growth and the impact of the higher interest rate environment. The $17.2 million decrease in non-interest income is primarily due to lower customer interest rate derivative activities, loan servicing fees, cash management fees, prepayment penalties, and syndication fees. The $7.9 million increase in non-interest expense is primarily due to an increase in both technology and employee-related costs in order to support balance sheet growth.

Comparison to Prior Year to Date

Commercial Banking's PPNR increased $99.8 million, or 19.3%, for the six months ended June 30, 2023, as compared to the six months ended June 30, 2022, due to an increase in net interest income, partially offset by a decrease in non-interest income and an increase in non-interest expense. The $147.4 million increase in net interest income is primarily due to organic loan growth and the impact of the higher interest rate environment. The $20.5 million decrease in non-interest income is primarily due to lower customer interest rate derivative activities, prepayment penalties, loan servicing fees, cash management fees, and direct investment income. The $27.1 million increase in non-interest expense is primarily due to the full year-to-date impact of expenses from the Sterling merger in 2023, as compared to the five months impact in 2022, and an increase in both technology and employee-related costs in order to support balance sheet growth.

Loans and leases increased $1.7 billion, or 4.4%, at June 30, 2023, as compared to December 31, 2022, primarily due to organic growth in the commercial non-mortgage and commercial real estate categories, partially offset by net principal paydowns in the equipment finance and asset-based lending categories. Total portfolio originations for the six months ended June 30, 2023, and 2022, were $5.1 billion and $6.2 billion, respectively. The $1.1 billion decrease was primarily due to a decrease in commercial real estate and commercial non-mortgage originations, partially offset by an increase in equipment finance originations.

Deposits decreased $1.2 billion, or 6.2%, at June 30, 2023, as compared to December 31, 2022, primarily due to customers rebalancing their deposit concentrations as a result of the high-profile bank failures in the first and second quarters of 2023.

Commercial Banking held $0.9 billion and $0.6 billion in assets under administration and $1.9 billion and $1.7 billion in assets under management at June 30, 2023, and December 31, 2022, respectively. The combined increase of $0.5 billion, or 22.1%, was primarily due to customers shifting their deposits into investment accounts to purchase U.S. Treasury securities with government-backing, and higher valuations in the equity markets during the six months ended June 30, 2023.

The $3.9 million decrease in non-interest income is primarily due to lower net investment services income driven by the outsourcing of the consumer investment services platform in the fourth quarter of 2022, partially offset by higher deposit and loan servicing fee income. The $12.9 million increase in non-interest expense is primarily due to the full year-to-date impact of expenses from the Sterling merger in 2023, as compared to the five months impact in 2022, partially offset by lower compensation and benefits expenses driven by the outsourcing of the consumer investment services platform effective as of the fourth quarter of 2022.

Selected Balance Sheet and Off-Balance Sheet Information:

(In thousands)	At June 30, 2023		At December 31, 2022
Loans	$	9,738,845	$	9,624,465
Deposits	23,874,970		23,609,941
Assets under administration (off-balance sheet)	7,847,996		7,872,397

Loans increased $0.1 billion, or 1.2%, at June 30, 2023, as compared to December 31, 2022, primarily due to growth in residential mortgages and small business commercial loans, partially offset by net principal paydowns in home equity balances and the continued run-off of Lending Club loans. Total portfolio originations for the six months ended June 30, 2023, and 2022, were $0.7 billion and $1.4 billion, respectively. The $0.7 billion decrease was primarily due to the increase in market rates, which resulted in lower residential mortgage originations.

Deposits increased $0.3 billion, or 1.1%, at June 30, 2023, as compared to December 31, 2022, as customer preferences shifted from lower rate checking and savings products into higher rate certificates of deposit and money market products.

Consumer Banking held approximately $7.8 billion and $7.9 billion in assets under administration at June 30, 2023, and December 31, 2022, respectively. The $24.4 million decrease was primarily due to customer investment outflows, partially offset by higher valuations in the equity markets during the six months ended June 30, 2023.

Financial Condition

Total assets increased $2.7 billion, or 3.9%, from $71.3 billion at December 31, 2022, to $74.0 billion at June 30, 2023. The change in total assets was primarily attributed to the following, which experienced changes greater than $100 million dollars:

•Interest-bearing deposits increased $0.5 billion, primarily due to the Company's risk management approach to hold higher levels of on-balance sheet liquidity in the second quarter of 2023.

•Total investment securities, net increased $0.2 billion, reflecting a $0.3 billion increase in the held-to-maturity portfolio, partially offset by a $0.1 billion decrease in the available-for-sale portfolio. The overall increase in investment securities was primarily due to purchases exceeding paydown activities, partially offset by the sale of $0.4 billion in U.S. Treasury notes, Corporate debt securities, and Municipal bonds and notes;

•Loans and leases increased $1.9 billion, primarily due to $5.8 billion of originations during the six months ended June 30, 2023, particularly across the commercial non-mortgage and commercial real estate categories, partially offset by net principal paydowns and commercial loan sales; and

•Goodwill and other net intangible assets increased a combined $138.7 million. Goodwill increased $117.4 million, which reflects the $143.2 million recognized in connection with the interLINK acquisition, partially offset by the impact of the Sterling merger measurement period adjustments recorded during the first quarter of 2023. The $21.3 million increase in other net intangible assets is primarily due to the $36.0 million broker dealer relationship and $4.0 million non-competition agreement recognized in connection with the interLINK acquisition, partially offset by year-to-date amortization charges.

Total liabilities increased $2.6 billion, or 4.0%, from $63.2 billion at December 31, 2022, to $65.8 billion at June 30, 2023. The change in total liabilities was primarily attributed to the following:

•Total deposits increased $4.7 billion, reflecting a $6.5 billion increase in interest-bearing deposits, partially offset by a $1.8 billion decrease in non-interest-bearing deposits. The overall increase in deposits is primarily due to the $4.3 billion of sweep money market deposits added as a result of the interLINK acquisition, partially offset by the impact of customers rebalancing their deposit concentrations as a result of the high-profile bank failures in the first and second quarters of 2023;

•Securities sold under agreements to repurchase and other borrowings decreased $0.9 billion, primarily due to $0.9 billion of federal funds purchased at December 31, 2022, as compared to none at June 30, 2023. The additional liquidity generated from the interLINK deposit sweep program allowed for the paydown of higher rate federal funds purchased during the first quarter of 2023;

•FHLB advances decreased $1.2 billion, primarily due to the maturity of the higher volume of advances borrowed in the first quarter of 2023, partially offset by the impact of the Company's risk management approach to hold higher levels of on-balance sheet liquidity in the second quarter of 2023;

•Long-term debt decreased $20.9 million, primarily due to the repurchase and retirement of $17.5 million of the 4.375% Senior fixed-rate notes due February 15, 2024;

•Accrued expenses and other liabilities decreased $76.7 million, primarily due to the payment of accreted employee bonuses in the first quarter of 2023, and decreases in accrued taxes, treasury derivative liabilities, and operating lease liabilities, partially offset by increases in accrued interest payable and unfunded LIHTC commitments.

Total stockholders' equity increased $0.2 billion, or 2.8%, from $8.1 billion at December 31, 2022, to $8.3 billion at
June 30, 2023. The change in total stockholders' equity was attributed to the following:

•The adoption of ASU No. 2022-02, which resulted in a $4.2 million cumulative-effect adjustment to retained earnings;

•Net income recognized of $456.0 million;

•Other comprehensive loss, net of tax, of $33.9 million, primarily due to market value decreases in the Company's
available-for-sale securities portfolio and cash flow hedges;

•Dividends paid to common and preferred stockholders of $139.8 million and $8.3 million, respectively;

•Employee stock-based compensation plan activity of $25.8 million, inclusive of restricted stock amortization and forfeitures, and stock options exercised of $1.7 million; and

•Repurchases of common stock of $58.3 million under the Company's common stock repurchase program and $15.4 million related to employee stock-based compensation plans.

Investment Securities

Through its Corporate Treasury function, the Company maintains and invests in debt securities that are primarily used to provide a source of liquidity for operating needs, to generate interest income, and as a means to manage the Company's
interest-rate risk. The Company's investment securities are classified into two major categories: available-for-sale and
held-to-maturity.

The ALCO manages the Company's securities in accordance with regulatory guidelines and corporate policies, which include limitations on aspects such as concentrations in and types of investments, as well as minimum risk ratings per type of security. In addition, the OCC may further establish individual limits on certain types of investments if the concentration in such investment presents a safety and soundness concern. At June 30, 2023, and December 31, 2022, the Company had investment securities with a total net carrying value of $14.7 billion and $14.5 billion, respectively, with an average risk weighting for regulatory purposes of 17.8% and 19.0%, respectively. Although the Bank held the entirety of the Company's investment portfolio at both June 30, 2023, and December 31, 2022, the Holding Company may also directly hold investments.

The following table summarizes the balances and percentage composition of the Company's investment securities:

	At June 30, 2023				At December 31, 2022
(In thousands)	Amount		%		Amount		%

Total held-to-maturity securities	$	6,944,000	100.0	%	$	6,564,879	100.0	%
Total investment securities	$	14,703,341			$	14,457,576

(1)The balances at both June 30, 2023, and December 31, 2022, exclude the $0.2 million ACL recorded on held-to-maturity securities.

Available-for-sale securities decreased $0.1 billion, or 1.7%, from $7.9 billion at December 31, 2022, to $7.8 billion at
June 30, 2023, primarily due to the sale of $0.4 billion in U.S. Treasury notes, Corporate debt securities, and Municipal bonds and notes during the six months ended June 30, 2023, which resulted in $20.5 million of gross realized losses, $3.8 million of which was attributed to a decline in credit quality and has been included in the Provision for credit losses. This decrease was partially offset by purchases exceeding paydown activities, particularly across the Agency MBS, Agency CMBS, and CMBS categories. The average FTE yield in the available-for-sale portfolio was 2.98% and 2.87% for the three and six months ended June 30, 2023, respectively, as compared to 2.20% and 2.10% for the three and six months ended June 30, 2022, respectively. The 78 and 77 basis point increases, respectively, are primarily due to higher market rates on securities purchased in 2023.

At June 30, 2023, and December 31, 2022, gross unrealized losses on available-for-sale securities were $883.0 million and $864.5 million, respectively. The $18.5 million increase is primarily due to higher market rates. Available-for-sale securities are evaluated for credit losses on a quarterly basis. No ACL was recorded on available-for-sale securities as of either period as each of the securities in the Company's portfolio are investment grade, current as to principal and interest, and their price changes are consistent with interest and credit spreads when adjusting for convexity, rating, and industry differences. At June 30, 2023, based on current market conditions and the Company's current targeted balance sheet composition strategy, the Company intends to hold its available-for-sale securities in unrealized loss positions through the anticipated recovery period, and it is more-likely-than-not that the Company will not have to sell these available-for-sale securities before the recovery of the entire amortized cost basis.

19

Held-to-maturity securities increased $0.3 billion, or 5.8%, from $6.6 billion at December 31, 2022, to $6.9 billion at
June 30, 2023, primarily due to purchases exceeding paydown activities, particularly across the Agency MBS and Agency CMBS categories. The average FTE yield in the held-to-maturity portfolio was 2.99% and 2.91% for the three and six months ended June 30, 2023, respectively, as compared to 2.25% and 2.15% for the three and six months ended June 30, 2022, respectively. The 74 and 76 basis point increases, respectively, are primarily due to higher market rates on securities purchased in 2023.

At June 30, 2023, and December 31, 2022, gross unrealized losses on held-to-maturity securities were $878.6 million and $806.2 million, respectively. The $72.4 million increase is primarily due to higher market rates. Held-to-maturity securities are evaluated for credit losses on a quarterly basis under the CECL methodology. At both June 30, 2023, and December 31, 2022, the ACL on held-to-maturity securities was $0.2 million.

Credit Policies and Procedures

The Bank has credit policies and procedures in place designed to support its lending activities within an acceptable level of risk, which are reviewed and approved by management and the Board of Directors on a regular basis. To assist with this process, management inspects reports generated by the Company's loan reporting systems related to loan production, loan quality, concentrations of credit, loan delinquencies, non-performing loans, and potential problem loans.

Commercial non-mortgage, asset-based, equipment finance, and warehouse lending loans are underwritten after evaluating and understanding the borrower’s ability to operate and service its debt. Assessment of the borrower's management is a critical element of the underwriting process and credit decision. Once it has been determined that the borrower’s management possesses sound ethics and a solid business acumen, current and projected cash flows are examined to determine the ability of the borrower to repay obligations, as contracted. Commercial non-mortgage, asset-based, and equipment finance loans are primarily made based on the identified cash flows of the borrower, and secondarily on the underlying collateral provided by the borrower. Warehouse lending loans are primarily made based on the borrower's ability to originate high-quality, first-mortgage residential loans that can be sold into the agency, government, or private jumbo markets, and secondarily on the underlying cash flows of the borrower. However, the cash flows of borrowers may not be as expected, and the collateral securing these loans, as applicable, may fluctuate in value. Most commercial non-mortgage, asset-based, and equipment finance loans are secured by the assets being financed and may incorporate personal guarantees of the principal balance. Warehouse lending loans are generally uncommitted facilities.

Commercial real estate loans, including multi-family, are subject to underwriting standards and processes similar to those for commercial non-mortgage, asset-based, equipment finance, and warehouse lending loans. These loans are primarily viewed as cash flow loans, and secondarily as loans secured by real estate. Repayment of commercial real estate loans is largely dependent on the successful operation of the property securing the loan, the market in which the property is located, and the tenants of the property securing the loan. The properties securing the Company’s commercial real estate portfolio are diverse in terms of type and geographic location, which reduces the Company's exposure to adverse economic events that may affect a particular market. Management monitors and evaluates commercial real estate loans based on collateral, geography, and risk grade criteria. All transactions are appraised to determine market value. Commercial real estate loans may be adversely affected by conditions in the real estate markets or in the general economy. Management periodically utilizes third-party experts to provide insight and guidance about economic conditions and trends affecting its commercial real estate loan portfolio.

Consumer loans are subject to policies and procedures developed to manage the specific risk characteristics of the portfolio. These policies and procedures, coupled with relatively small individual loan amounts and predominately collateralized loan structures, are spread across many different borrowers, minimizing the level of credit risk. Trend and outlook reports are reviewed by management on a regular basis, and policies and procedures are modified or developed, as needed. Underwriting factors for residential mortgage and home equity loans include the borrower’s FICO score, the loan amount relative to property value, and the borrower’s debt-to-income level. The Bank originates both qualified mortgage and non-qualified mortgage loans, as defined by applicable CFPB rules.

Allowance for Credit Losses on Loans and Leases

The ACL on loans and leases increased $34.2 million, or 5.7%, from $594.7 million at December 31, 2022, to $628.9 million at June 30, 2023, due to the impact of the current macroeconomic environment on credit performance and organic loan growth.

The following table summarizes the percentage allocation of the ACL across the loans and leases categories:

	At June 30, 2023				At December 31, 2022
(Dollars in thousands)	Amount		% (1)		Amount		% (1)

Methodology

The Company's ACL on loans and leases is considered to be a critical accounting policy. The ACL on loans and leases is a contra-asset account that offsets the amortized cost basis of loans and leases for the credit losses that are expected to occur over the life of the asset. Executive management reviews and advises on the adequacy of the allowance, which is maintained at a level that management deems to be sufficient to cover expected losses within the loan and lease portfolios.

The ACL on loans and leases is determined using the CECL model, whereby an expected lifetime credit loss is recognized at the origination or purchase of an asset, including those acquired through a business combination, which is then reassessed at each reporting date over the contractual life of the asset. The calculation of expected credit losses includes consideration of past events, current conditions, and reasonable and supportable economic forecasts that affect the collectability of the reported amounts. Generally, expected credit losses are determined through a pooled, collective assessment of loans and leases with similar risk characteristics. However, if the risk characteristics of a loan or lease change such that it no longer matches that of the collectively assessed pool, it is removed from the population and individually assessed for credit losses. The total ACL on loans and leases recorded by management represents the aggregated estimated credit loss determined through both the collective and individual assessments.

Collectively Assessed Loans and Leases. Collectively assessed loans and leases are segmented based on product type, credit quality, risk ratings, and/or collateral types within its commercial and consumer portfolios, and expected losses are determined using a PD, LGD, and EAD, loss rate, or discounted cash flow framework.

For portfolios using the PD/LGD/EAD framework, credit losses are calculated as the product of the probability of a loan defaulting, expected loss given the occurrence of a default, and the expected exposure of a loan at default. Summing the product across loans over their lives yields the lifetime expected credit losses for a given portfolio. Management's PD and LGD calculations are predictive models that measure the current risk profile of the loan pools using forecasts of future macroeconomic conditions, historical loss information, loan-level risk attributes, and credit quality indicators. The calculation of EAD follows an iterative process to determine the expected remaining principal balance of a loan based on historical paydown rates for loans of a similar segment within the same portfolio. The calculation of portfolio exposure in future quarters incorporates expected losses, the loan's amortization schedule, and prepayment rates.

Under the loss rate method, expected credit losses are estimated using a loss rate that is multiplied by the amortized cost of the asset at the balance sheet date. For each loan segment identified above, management applies an expected historical loss trend based on third-party loss estimates, and correlates them to observed economic metrics and reasonable and supportable forecasts of economic conditions. Under the discounted cash flow method, expected credit losses are determined by comparing the amortized cost of the asset at the balance sheet date to the present value of estimated future principal and interest payments expected to be collected over the remaining life of the asset. The Company's loss model generates cash flow projections at the loan level based on reasonable and supportable projections, from which management estimates payment collections adjusted for accelerated payments, recovery time, PD, and LGD.

The Company's models incorporate a single economic forecast scenario and macroeconomic assumptions over a reasonable and supportable forecast period. The development of the reasonable and supportable forecast assumes each macroeconomic variable will revert to long-term expectations, with reversion characteristics unique to specific economic indicators and forecasts. Reversion towards long-term expectations generally begins two to three years from the forecast start date and is complete within three to five years. Certain models use output reversion and revert to mean historical portfolio loss rates on a
straight-line basis in the third year of the forecast. Other models use input reversion and revert to the mean of macroeconomic variables in reasonable and supportable forecasts.

The Company incorporates forecasts of macroeconomic variables in the determination of expected credit losses. Macroeconomic variables are selected for each class of financing receivable based on relevant factors, such as asset type and the correlation of the variables to credit losses, among others. Data from the forecast scenario of these variables is used as an input to the modeled loss calculation.

A portion of the collective ACL is comprised of qualitative adjustments for risk characteristics that are not reflected or captured in the quantitative models, but are likely to impact the measurement of estimated credit losses. Qualitative factors are based on management's judgement of the Company, market, industry, or business specific data including loan trends, portfolio segment composition, and loan rating or credit scores. Qualitative adjustments may be applied in relation to economic forecasts when relevant facts and circumstances are expected to impact credit losses, particularly in times of significant volatility in economic activity.

23

Individually Assessed Loans and Leases. If the risk characteristics of a loan or lease change such that it no longer matches the risk characteristics of the collectively assessed pool, it is removed from the population and individually assessed for credit losses. Generally, all non-accrual loans, loans with a charge-off, and collateral dependent loans where the borrower is experiencing financial difficulty, are individually assessed. The measurement method used to calculate the expected credit loss on an individually assessed loan or lease is dependent on the type and whether the loan or lease is considered to be collateral dependent. Methods for collateral dependent loans are either based on the fair value of the collateral less estimated cost to sell (when the basis of repayment is the sale of collateral), or the present value of the expected cash flows from the operation of the collateral. For non-collateral dependent loans, either a discounted cash flow method or other loss factor method is used. Any individually assessed loan or lease for which no specific valuation allowance is deemed necessary is either the result of sufficient cash flows or sufficient collateral coverage relative to the amortized cost of the asset.

Additional information regarding the Company's ACL methodology can be found within Note 1: Summary of Significant Accounting Policies in the Consolidated Financial Statements contained in Part II - Item 8. Financial Statements and Supplementary Data of the Company's Annual Report on Form 10-K for the year ended December 31, 2022.

Asset Quality Ratios

The Company manages asset quality using risk tolerance levels established through the Company's underwriting standards, servicing, and management of its loan and lease portfolio. Loans and leases for which a heightened risk of loss has been identified are regularly monitored to mitigate further deterioration and preserve asset quality in future periods. Non-performing assets, credit losses, and net charge-offs are considered by management to be key measures of asset quality.

The following table summarizes key asset quality ratios and their underlying components:

(1)Percentage represents annualized year-to-date net charge-offs (recoveries) to average loans and leases within the comparable category.

Net charge-offs as a percentage of average loans and leases were 0.16% and 0.09% for the three months ended June 30, 2023, and 2022, respectively, and 0.18% and 0.09% for the six months ended June 30, 2023, and 2022, respectively. The increased level of net charge-offs is primarily due to the impact of the current macroeconomic environment on credit performance and a loss on sale of commercial real estate loans, which were charged-off in the second quarter of 2023.

Liquidity and Capital Resources

The Company manages its cash flow requirements through proactive liquidity measures at both the Holding Company and the Bank. In order to maintain stable, cost-effective funding, and to promote overall balance sheet strength, the liquidity position of the Company is continuously monitored, and adjustments are made to balance sources and uses of funds, as appropriate.

At June 30, 2023, management is not aware of any events that are reasonably likely to have a material adverse effect on the Company’s liquidity position, capital resources, or operating activities. Although regulatory agencies have not issued formal guidance mandating more stringent liquidity and capital requirements, the Company is anticipating a greater focus on the liquidity and capital adequacy of financial institutions in response to the high-profile bank failures that occurred during the first and second quarters of 2023, and has taken appropriate measures to mitigate the risk that such requirements, if implemented, may have on its business, financial positions, and results of operations.

Cash inflows are provided through a variety of sources, including principal and interest payments on loans and investments, unpledged securities that can be sold or utilized to secure funding, and new deposits. The Company is committed to maintaining a strong base of core deposits, which consists of demand, interest-bearing checking, savings, health savings, and money market accounts, to support growth in its loan portfolios. Management actively monitors the interest rate environment and makes adjustments to its deposit strategy in response to evolving market conditions, bank funding needs, and client relationship dynamics.

25

Holding Company Liquidity. The primary source of liquidity at the Holding Company is dividends from the Bank. To a lesser extent, investment income, net proceeds from investment sales, borrowings, and public offerings may provide additional liquidity. The Holding Company generally uses its funds for principal and interest payments on senior notes, subordinated notes, and junior subordinated debt, dividend payments to preferred and common stockholders, repurchases of its common stock, and purchases of investment securities, as applicable.

During the three and six months ended June 30, 2023, the Bank paid $100.0 million and $250.0 million in dividends to the Holding Company, respectively. At June 30, 2023, there was $708.8 million of retained earnings available for the payment of dividends by the Bank to the Holding Company. On July 19, 2023, the Bank was approved to pay the Holding Company $250.0 million in dividends for the third quarter of 2023.

There are certain restrictions on the Bank's payment of dividends to the Holding Company, which can be found within
Note 10: Regulatory Capital and Restrictions in the Notes to Condensed Consolidated Financial Statements contained in Part I - Item 1. Financial Statements of this report, and in the section captioned "Supervision and Regulation" in Part I - Item 1. Business of the Company's Annual Report on Form 10-K for the year ended December 31, 2022.

The quarterly cash dividend to common stockholders remained at $0.40 per common share during the three months ended
June 30, 2023. On July 19, 2023, it was announced that the Holding Company’s Board of Directors had declared a quarterly cash dividend of $0.40 per share on Webster common stock. For the Series F Preferred Stock and Series G Preferred Stock, quarterly cash dividends of $328.125 per share and $16.25 per share were declared, respectively. The Company continues to monitor economic forecasts, anticipated earnings, and its capital position in the determination of its dividend payments.

The Holding Company maintains a common stock repurchase program, which was approved by the Board of Directors, that authorizes management to purchase shares of its common stock in open market or privately negotiated transactions, through block trades, and pursuant to any adopted predetermined trading plan, subject to certain conditions. During the three months ended June 30, 2023, the Holding Company repurchased 1,465,673 shares under the program at a weighted-average price of $39.57 per share, totaling $58.0 million. The Holding Company's remaining purchase authority at June 30, 2023, was $343.3 million. In addition, the Company will periodically acquire common shares outside of the repurchase program related to employee stock compensation plan activity. During the three months ended June 30, 2023, the Company repurchased 8,750 shares at a weighted-average price of $34.79 per share, totaling $0.3 million for this purpose.

The IRA imposes a 1% excise tax on the value of net stock repurchased by certain publicly traded corporations, including the Company, after December 31, 2022. At June 30, 2023, the Company had recorded a $0.3 million liability for such excise tax owed, with an offset to Treasury stock on the Condensed Consolidated Balance Sheet.

Webster Bank Liquidity. The Bank's primary source of funding is core deposits. Including time deposits, the Bank had a loan to total deposit ratio of 87.9% and 92.1% at June 30, 2023, and December 31, 2022, respectively.

The Bank is required by OCC regulations to maintain a sufficient level of liquidity to ensure safe and sound operations. The adequacy of liquidity, as assessed by the OCC, depends on factors such as overall asset and liability structure, market conditions, competition, and the nature of the institution’s deposit and loan customers. At June 30, 2023, the Bank exceeded all regulatory liquidity requirements. The Company has designed a detailed contingency plan in order to respond to any liquidity concerns in a prompt and comprehensive manner, including early detection of potential problems and corrective action to address liquidity stress scenarios.

Capital Requirements. The Holding Company and the Bank are subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory actions by regulators that could have a direct material effect on the Company’s Consolidated Financial Statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, both the Holding 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 regulatory directives. Capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors.

Quantitative measures established by the Basel III Capital Rules to ensure capital adequacy require financial institutions to maintain minimum ratios of Common Equity Tier 1 Capital, defined by the Basel III capital rules (CET1 capital), Tier 1 capital, Total capital to risk-weighted assets, and Tier 1 capital to average tangible assets (as defined in the regulations). At June 30, 2023, both the Holding Company and the Bank were classified as well-capitalized. Management believes that no events or changes have occurred subsequent to quarter-end that would change this designation.

26

In accordance with regulatory capital rules, the Company elected an option to delay the estimated impact of the adoption of CECL on its regulatory capital over a two-year deferral period, which ended on January 1, 2022, and subsequent three-year transition period ending on December 31, 2024. During the three-year transition period, capital ratios will phase out the aggregate amount of the regulatory capital benefit provided from the delayed CECL adoption in the initial two years. For 2022, 2023, and 2024, the Company is allowed 75%, 50%, and 25%, respectively, of the regulatory capital benefit as of
December 31, 2021, with full absorption occurring in 2025. At June 30, 2023, the regulatory capital benefit allowed from the delayed CECL adoption resulted in a 6, 6, and 4 basis point increase to the Holding Company's and the Bank's CET1 capital to total risk-weighted assets (CET1 risk-based capital), Tier 1 capital to total risk-weighted assets (Tier 1 risk-based capital), and Tier 1 capital to average tangible assets (Tier 1 leverage capital), respectively, and a 1 basis point decrease to Total capital to total risk-weighted assets (Total risk-based capital). Both the Holding Company's and the Bank's regulatory ratios remain in excess of being well-capitalized, even without the regulatory capital benefit of the delayed CECL adoption impact.

Additional information regarding the required regulatory capital levels and ratios applicable to the Holding Company and the Bank can be found within Note 10: Regulatory Capital and Restrictions in the Notes to Condensed Consolidated Financial Statements contained in Part I -Item 1. Financial Statements.

Sources and Uses of Funds

Sources of Funds. Deposits are the primary source of cash flows for the Bank’s lending activities and general operational needs. Loan and securities repayments, proceeds from loans and securities held for sale, and maturities also provide cash flows. While scheduled loan and securities repayments are a relatively stable source of funds, prepayments and other deposit inflows are influenced by economic conditions and prevailing interest rates, the timing of which is inherently uncertain. Additional sources of funds are provided by both short-term and long-term borrowings, and to a lesser extent, dividends received as part of the Bank's membership with the FHLB and FRB.

Deposits. The Bank offers a wide variety of checking and savings deposit products designed to meet the transactional and investment needs of both its consumer and business customers. The Bank’s deposit services include, but are not limited to, ATM and debit card use, direct deposit, ACH payments, mobile banking, internet-based banking, banking by mail, account transfers, and overdraft protection, among others. The Bank manages the flow of funds in its deposit accounts and interest rates consistent with FDIC regulations. The Bank’s Consumer and Digital Pricing Committee and its Commercial and Institutional Liability and Loan Pricing Committee both meet regularly to determine pricing and marketing initiatives.

With the acquisition of interLINK during the first quarter of 2023, the Bank received $4.3 billion of money market deposits at June 30, 2023, which added a unique source of core deposit funding and scalable liquidity to the Company's already differentiated, omnichannel deposit gathering capabilities.

Total deposits were $58.7 billion and $54.0 billion at June 30, 2023, and December 31, 2022, respectively. The $4.7 billion increase was primarily due to the interLINK money market deposits and organic deposit growth, partially offset by customers rebalancing their deposit concentrations as a result of the high-profile bank failures in the first and second quarters of 2023. Customer preferences also shifted from lower rate checking and savings products into higher rate certificates of deposit products, which are currently more attractive in the higher interest rate environment.

The following table summarizes daily average balances of deposits by type and the weighted-average rates paid thereon:

Uninsured deposits represent the portion of deposit accounts in U.S. offices that exceed the FDIC insurance limit or similar state deposit insurance regime, and amounts in any other uninsured investment or deposit accounts that are classified as deposits and not subject to any federal or state deposit insurance regimes. The Company calculates its uninsured deposit balances based on the methodologies and assumptions used for regulatory reporting requirements, which includes an estimated portion, and affiliate deposits. At June 30, 2023, and December 31, 2022, total uninsured deposits as per regulatory reporting requirements and reported on Schedule RC-O of the Bank's Call Report were $21.0 billion and $22.5 billion, respectively.

The following table summarizes uninsured deposits information at June 30, 2023, after certain exclusions:

(In thousands)	At June 30, 2023
Uninsured deposits, per regulatory reporting requirements	$	20,988,997
Less: Affiliate deposits	(2,129,206)
Collateralized deposits	(4,459,545)
Uninsured deposits, after exclusions	$	14,400,246
Immediately available liquidity (1)	$	17,946,687
Uninsured deposits coverage	124.6%

(1)Reflects $11.6 billion and $3.6 billion of additional borrowing capacity from the FHLB and the FRB, respectively, and $2.8 billion in unencumbered liquid assets.

Uninsured deposits, after adjusting for affiliate deposits and collateralized deposits, represented 24.5% of total deposits at June 30, 2023. Management believes that this presentation provides a more accurate view of deposits at risk given that affiliate deposits are not customer facing, and therefore are eliminated upon consolidation, and collateralized deposits are secured by other means. As of the date of this Quarterly Report on Form 10-Q, the Company's uninsured deposits as a percentage of total deposits, adjusted for affiliate deposits and collateralized deposits, is consistent with the percentage reported at
June 30, 2023. In addition, the Company's immediately available liquidity continues to increase.

The following table summarizes the portion of U.S. time deposits in excess of the FDIC insurance limit and time deposits otherwise uninsured by contractual maturity:

(In thousands)	June 30, 2023
Portion of U.S. time deposits in excess of insurance limit	$	2,908,203
Time deposits otherwise uninsured with a maturity of:
3 months or less	$	585,911
Over 3 months through 6 months	1,872,380
Over 6 months through 12 months	441,155
Over 12 months	8,757

Additional information regarding period-end deposit balances and rates can be found within Note 7: Deposits in the Notes to Condensed Consolidated Financial Statements contained in Part I - Item 1. Financial Statements.

Borrowings. The Bank's primary borrowing sources include securities sold under agreements to repurchase, federal funds purchased, FHLB advances, and long-term debt. Total borrowed funds were $5.6 billion and $7.7 billion at June 30, 2023, and December 31, 2022, respectively, and represented 7.6% and 10.8% of total assets, respectively. The $2.1 billion decrease is primarily due to a $1.2 billion decrease in FHLB advances and a $0.9 billion decrease in federal funds purchased.

The Bank had additional borrowing capacity from the FHLB of $11.6 billion and $4.3 billion at June 30, 2023, and December 31, 2022, respectively. The Bank also had additional borrowing capacity from the FRB of $3.6 billion and $1.2 billion at June 30, 2023, and December 31, 2022, respectively. Unpledged investment securities of $1.6 billion at
June 30, 2023, could have been used for collateral on borrowings or to increase borrowing capacity by either $1.4 billion with the FHLB or $1.7 billion with the FRB.

Securities sold under agreements to repurchase are generally a form of short-term funding for the Bank in which it sells securities to counterparties with an agreement to buy them back in the future at a fixed price. Securities sold under agreements to repurchase totaled $243.6 million and $282.0 million at June 30, 2023, and December 31, 2022, respectively. The $38.4 million decrease is primarily due to fluctuations in customers' overnight account balances.

The Bank may also purchase term and overnight federal funds to meet its short-term liquidity needs. There were no federal funds purchased at June 30, 2023, whereas federal funds purchased totaled $0.9 billion at December 31, 2022. The additional liquidity generated from the interLINK deposit sweep program allowed for the paydown during the first quarter of 2023 of higher rate federal funds purchased.

29

FHLB advances are not only utilized as a source of funding, but also for interest rate risk management purposes. FHLB advances totaled $4.3 billion and $5.5 billion at June 30, 2023, and December 31, 2022, respectively. The $1.2 billion decrease is primarily due to the maturity of the higher volume of advances borrowed in the first quarter of 2023, partially offset by the impact of the Company's risk management approach to hold higher levels of on-balance sheet liquidity in the second quarter of 2023.

Long-term debt consists of senior fixed-rate notes maturing in 2024 and 2029, subordinated fixed-to-floating-rate notes maturing in 2029 and 2030, and floating-rate junior subordinated notes maturing in 2033. Long-term debt remained relatively flat on a comparative basis, totaling approximately $1.1 billion at both June 30, 2023, and December 31, 2022, respectively.

Federal Home Loan Bank and Federal Reserve Bank Stock. The Bank is a member of the FHLB System, which consists of eleven district Federal Home Loan Banks, each of which is subject to the supervision and regulation of the Federal Housing Finance Agency. An activity-based capital stock investment in the FHLB is required in order for the Bank to maintain its membership and access to advances and other extensions of credit for sources of funds and liquidity purposes. The FHLB capital stock investment is restricted as there is no market for it, and it can only be redeemed by the FHLB. The Bank held FHLB capital stock of $181.1 million and $221.4 million at June 30, 2023, and December 31, 2022, respectively. The most recent FHLB quarterly cash dividend was paid on August 2, 2023, in an amount equal to an annual yield of 8.04%.

The Bank is also required to hold FRB stock equal to 6% of its capital and surplus, of which 50% is paid. The remaining 50% is subject to call when deemed necessary by the Federal Reserve System. Similar to FHLB stock, the FRB capital stock investment is restricted as there is no market for it, and it can only be redeemed by the FRB. The Bank held FRB capital stock of $226.9 million and $224.5 million at June 30, 2023, and December 31, 2022, respectively. The most recent FRB semi-annual cash dividend was paid on June 30, 2023, in an amount equal to an annual yield of 3.79%.

Uses of Funds. The Company enters into various contractual obligations in the normal course of business that require future cash payments and that could impact its short-term and long-term liquidity and capital resource needs. The following table summarizes significant fixed and determinable contractual obligations at June 30, 2023. The actual timing and amounts of future cash payments may differ from the amounts presented. Based on the Company's current liquidity position, it is expected that our sources of funds will be sufficient to fulfill these obligations when they come due.

	Payments Due by Period (1)
(In thousands)	2023		2024		2025		2026		2027		Thereafter		Total

(1)Interest payments on borrowings have been excluded.

(2)Purchase obligations represent agreements to purchase goods or services of $1.0 million or more that are enforceable and legally binding and specify all significant terms.

In addition, in the normal course of business, the Company offers financial instruments with off-balance sheet risk to meet the financing needs of its customers. These transactions include commitments to extend credit, and commercial and standby letters of credit, which involve to a varying degree, elements of credit risk. Since many of these commitments are expected to expire unused or be only partially funded, the total commitment amount of $11.2 billion at June 30, 2023, does not necessarily reflect future cash payments.

The Company also enters into commitments to invest in venture capital and private equity funds, as well as LIHTC investments to assist the Bank in meeting its responsibilities under the CRA. The total unfunded commitment for these alternative investments was $490.7 million at June 30, 2023. However, the timing of capital calls cannot be reasonably estimated, and depending on the nature of the contract, the entirety of the capital committed by the Company may not be called.

Pension obligations are funded by the Company, as needed, to provide for participant benefit payments as it relates to the Company's frozen, non-contributory, qualified defined benefit pension plan. Decisions to contribute to the defined benefit pension plan are made based upon pension funding requirements under the Pension Protection Act, the maximum amount deductible under the Internal Revenue Code, the actual performance of plan assets, and trends in the regulatory environment. The Company does not currently anticipate that it will be required to contribute to the defined benefit pension plan in 2023. The Company's non-qualified supplemental executive retirement plans and other post-employment benefit plans are unfunded.

At June 30, 2023, the Company's Condensed Consolidated Balance Sheet reflects a liability for uncertain tax positions of $10.1 million and $2.3 million of accrued interest and penalties, respectively. The ultimate timing and amount of any related future cash settlements cannot be predicted with reasonable certainty.

On May 22, 2023, the FDIC published a proposed rule to charge certain banks a special assessment to recover losses incurred by protecting uninsured depositors of Silicon Valley Bank and Signature Bank upon their failure in March 2023. The proposed rule would levy a special assessment to certain banks at an annual rate of 12.5 basis points based on their uninsured deposits balance as of December 31, 2022, payable in eight quarterly installments beginning in the first quarter of 2024. Based on the proposed rule, the Company estimates that its total special assessment charge would be approximately $44.0 million. The FDIC has the authority to make further changes to the proposed rule before finalization, including changes to the underlying data or calculation methodology used to determine the special assessment. However, since the final rule has not yet been published in the Federal Register, no legal obligation has been incurred, and therefore, no accrual has been recognized.

Note 18: Commitments and Contingencies and Note 11: Variable Interest Entities, respectively, in the Notes to the Condensed Consolidated Financial Statements contained in Part I - Item 1. Financial Statements of this report. Additional information regarding defined benefit pension and other postretirement benefit plans and income taxes can be found within
Note 19: Retirement Benefit Plans and Note 9: Income Taxes, respectively, in the Notes to the Consolidated Financial Statements contained in Part II - Item 8. Financial Statements and Supplementary Data of the Company's Annual Report on Form 10-K for the year ended December 31, 2022.

Asset/Liability Management and Market Risk

An effective asset/liability management process must balance the risks and rewards from both short-term and long-term interest rate risk when determining the Company's strategy and action. To facilitate this process, interest rate sensitivity is monitored on an ongoing basis by the Company's ALCO, whose primary goal is to manage interest rate risk and maximize net income and net economic value over time in changing interest rate environments. The ALCO meets frequently to make decisions on the Company's investment and funding portfolios based on the economic outlook, its interest rate expectations, the risk position, and other factors.

Four main tools are used for managing interest rate risk:

•the size, duration, and credit risk of the investment portfolio;

•the size and duration of the wholesale funding portfolio;

•interest rate contracts; and

•the pricing and structure of loans and deposits.

Management measures interest rate risk using simulation analysis and asset/liability modeling software to calculate the Company's earnings at risk and equity at risk. Interest rates are generally assumed to change up or down in a parallel fashion, and the net interest income results in each scenario are compared to a flat rate base scenario. The flat rate base scenario holds the end of period yield curve constant over a twelve-month forecast horizon. At June 30, 2023, and December 31, 2022, the flat rate base scenario assumed a federal funds rate of 5.25% and 4.50%, respectively. The federal funds rate target range was 5.00-5.25% at June 30, 2023, and 4.25-4.50% at December 31, 2022. Since interest rates rose sharply in 2022 and into the first quarter of 2023, and have since remained elevated, management has incorporated the up and down 300 basis point rate scenarios back into its assessment of interest rate risk.

The following table summarizes the estimated impact that gradual parallel changes in interest rates of up and down 100, 200, and 300 basis points might have on the Company's net interest income over a twelve-month period starting at June 30, 2023, and December 31, 2022, as compared to actual net interest income and assuming no changes in interest rates:

	-300bp	-200bp	-100bp	+100bp	+200bp	+300bp
June 30, 2023	(7.5)%	(4.6)%	(2.1)%	1.5%	3.2%	5.4%
December 31, 2022	n/a	(6.9)%	(3.3)%	3.2%	6.5%	n/a

Asset sensitivity in terms of net interest income decreased at June 30, 2023, as compared to December 31, 2022, primarily due to changes in the overall balance sheet composition, which included the addition of $4.3 billion in price-sensitive deposits from interLINK, an increase in interest paid on deposits, and the implementation of incremental asset sensitivity measures, such as hedges and collars, during the six months ended June 30, 2023. Loans at floors were $0.4 billion at both December 31, 2022, and June 30, 2023. While loans with floors, which are considered “in the money”, have the impact of reducing overall asset sensitivity, as interest rates continue to rise, these loans will move through their floors and reprice accordingly.

The following table summarizes the estimated impact that yield curve twists or immediate non-parallel changes in interest rates of up and down 50 and 100 basis points might have on the Company's net interest income for the subsequent twelve-month period starting at June 30, 2023, and December 31, 2022:

	Short End of the Yield Curve				Long End of the Yield Curve
	-100bp	-50bp	+50bp	+100bp	-100bp	-50bp	+50bp	+100bp
June 30, 2023	(2.4)%	(1.1)%	0.5%	0.9%	(1.9)%	(0.9)%	1.0%	2.0%
December 31, 2022	(4.2)%	(2.0)%	1.7%	3.3%	(2.4)%	(1.2)%	1.3%	2.6%

These non-parallel scenarios are modeled with the short end of the yield curve moving up or down 50 and 100 basis points, while the long end of the yield curve remains unchanged, and vice versa. The short end of the yield curve is defined as terms less than eighteen months and the long end of the yield curve is defined as terms greater than eighteen months. The results reflect the annualized impact of immediate interest rate changes.

Sensitivity to both the short end and the long end of the yield curve for net interest income decreased at June 30, 2023, as compared to December 31, 2022, primarily due to changes in the overall balance sheet composition.

The following table summarizes the estimated economic value of financial assets, financial liabilities, and off-balance sheet financial instruments and the corresponding estimated change in economic value if interest rates were to instantaneously increase or decrease by 100 basis points at June 30, 2023, and December 31, 2022:

(Dollars in thousands)	Book Value		Estimated Economic Value		Estimated Economic Value Change
					-100 bp			+100 bp
June 30, 2023
Assets	$	74,038,243	$	69,062,109	$	1,330,492		$	(1,330,235)
Liabilities	65,758,517		59,909,012		1,985,292			(1,726,114)
Net	$	8,279,726	$	9,153,097	$	(654,800)		$	395,879
Net change as % base net economic value					(7.2)		%	4.3		%
December 31, 2022
Assets	$	71,277,521	$	67,920,989	$	1,161,794		$	(1,247,083)
Liabilities	63,221,335		55,951,495		1,959,399			(1,716,697)
Net	$	8,056,186	$	11,969,494	$	(797,605)		$	469,614
Net change as % base net economic value					(6.7)		%	3.9		%

Changes in economic value can best be described through duration, which is a measure of the price sensitivity of financial instruments due to changes in interest rates. For fixed-rate financial instruments, it can be thought of as the weighted-average expected time to receive future cash flows, whereas for floating-rate financial instruments, it can be thought of as the
weighted-average expected time until the next rate reset. Overall, the longer the duration, the greater the price sensitivity due to changes in interest rates. Generally, increases in interest rates reduce the economic value of fixed-rate financial assets as future discounted cash flows are worth less at higher interest rates. In a rising interest rate environment, the economic value of financial liabilities decreases for the same reason. A reduction in the economic value of financial liabilities is a benefit to the Company. Floating-rate financial instruments may have durations as short as one day, and therefore, may have very little price sensitivity due to changes in interest rates.

Duration gap represents the difference between the duration of financial assets and financial liabilities. A duration gap at or near zero would imply that the balance sheet is matched, and therefore, would exhibit no change in estimated economic value for changes in interest rates. At June 30, 2023, and December 31, 2022, the Company's duration gap was negative 1.1 years and negative 1.4 years, respectively. A negative duration gap implies that the duration of financial liabilities is longer than the duration of financial assets, and therefore, liabilities have more price sensitivity than assets and will reset their interest rates at a slower pace. Consequently, the Company's net estimated economic value would generally be expected to increase when interest rates rise, as the benefit of the decreased value of financial liabilities would more than offset the decreased value of financial assets. The opposite would generally be expected to occur when interest rates fall. Earnings would also generally be expected to increase when interest rates rise, and decrease when interest rates fall over the long term, absent the effects of any new business booked in the future.

These earnings and net economic value estimates are subject to factors that could cause actual results to differ, and also assume that management does not take any additional action to mitigate any positive or negative effects from changing interest rates. Management believes that the Company's interest rate risk position at June 30, 2023, represents a reasonable level of risk given the current interest rate outlook. Management continues to monitor interest rates and other relevant factors given recent market volatility and is prepared to take additional action, as necessary.

Critical Accounting Estimates

The preparation of the Company's Condensed Consolidated Financial Statements, and accompanying notes thereto, in accordance with GAAP and practices generally applicable to the financial services industry, requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, expenses, and the disclosure of contingent assets and liabilities. While management's estimates are made based on historical experience, current available information, and other factors that are deemed to be relevant, actual results could significantly differ from those estimates.

Accounting estimates are necessary in the application of certain accounting policies and can be susceptible to significant change in the near term. Critical accounting estimates are those estimates made in accordance with GAAP that involve a significant level of estimation uncertainty and have had, or are reasonably likely to have, a material impact on the Company's financial condition or results of operations. Management has identified that the Company's most critical accounting estimates are those related to the ACL on loans and leases and business combinations accounting policies. These accounting policies and their underlying estimates are discussed directly with the Audit Committee of the Board of Directors.

Allowance for Credit Losses on Loans and Leases

The ACL on loans and leases is a reserve established through a provision for credit losses charged to expense, which represents management’s best estimate of expected lifetime credit losses within the Company's loan and lease portfolios at the balance sheet date. The calculation of expected credit losses is determined using predictive methods and models that follow a
PD/LGD/EAD, loss rate, or discounted cash flow framework, and include consideration of past events, current conditions, macroeconomic variables (i.e., unemployment, gross domestic product, property values, and interest rate spreads), and reasonable and supportable economic forecasts that affect the collectability of the reported amounts. Changes to the ACL on loans and leases, and therefore, to the related provision for credit losses, can materially affect financial results.

The determination of the appropriate level of ACL on loans and leases inherently involves a high degree of subjectivity and requires the Company to make significant estimates of current credit risks and trends using existing qualitative and quantitative information, and reasonable and supportable forecasts of future economic conditions, all of which may undergo frequent and material changes. Changes in economic conditions affecting borrowers and macroeconomic variables that the Company is more susceptible to, unforeseen events such as natural disasters and pandemics, along with new information regarding existing loans, identification of additional problem loans, the fair value of underlying collateral, and other factors, both within and outside the Company's control, may indicate the need for an increase or decrease in the ACL on loans and leases.

It is difficult to estimate the sensitivity of how potential changes in any one economic factor or input might affect the overall reserve because a wide variety of factors and inputs are considered in estimating the ACL and changes in those factors and inputs considered may not occur at the same rate and may not be consistent across all product types. Further, changes in factors and inputs may also be directionally inconsistent, such that improvement in one factor may offset deterioration in others.

Executive management reviews and advises on the adequacy of the ACL on loans and leases on a quarterly basis. Although the overall balance is determined based on specific portfolio segments and individually assessed assets, the entire balance is available to absorb credit losses for any of the loan and lease portfolios.

Additional information regarding the determination of the ACL on loans and leases, including the Company's valuation methodology, can be found under the section captioned "Allowance for Credit Losses on Loans and Leases" contained elsewhere in this Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations, and within Note 1: Summary of Significant Accounting Policies in the Notes to Consolidated Financial Statements contained in
Part II - Item 8. Financial Statements and Supplementary Data included in the Company's Annual Report on Form 10-K for the year ended December 31, 2022.

Business Combinations

The acquisition method of accounting generally requires that the identifiable assets acquired and liabilities assumed in business combinations are recorded at fair value as of the acquisition date. The determination of fair value often involves the use of internal or third-party valuation techniques, such as discounted cash flow analyses or appraisals. Particularly, the valuation techniques used to estimate the fair value of loans and leases and the core deposit intangible asset acquired in the Sterling merger include estimates related to discount rates, credit risk, and other relevant factors, which are inherently subjective. A description of the valuation methodologies used to estimate the fair values of the significant assets acquired and liabilities assumed from the Sterling merger can be found within Note 2: Mergers and Acquisitions in the Notes to Consolidated Financial Statements contained in Part II - Item 8. Financial Statements and Supplementary Data included in the Company's Annual Report on Form 10-K for the year ended December 31, 2022.

Note 1: Summary of Significant Accounting Policies

Nature of Operations

Webster Financial Corporation is a bank holding company and financial holding company under the BHC Act, incorporated under the laws of Delaware in 1986, and headquartered in Stamford, Connecticut. Webster Bank, along with its HSA Bank division, is a leading commercial bank in the Northeast that delivers a wide range of digital and traditional financial solutions to businesses, individuals, families, and partners across its three differentiated lines of business: Commercial Banking, HSA Bank, and Consumer Banking. While its core footprint spans from New York to Rhode Island and Massachusetts, certain businesses operate in extended geographies. HSA Bank is one of the largest providers of employee benefit solutions in the United States.

Basis of Presentation

The unaudited Condensed Consolidated Financial Statements of the Company have been prepared in accordance with GAAP for interim financial information and Article 10 of Regulation S-X. Certain information and footnote disclosures required by GAAP for complete financial statements have been omitted or condensed. Therefore, the condensed consolidated financial statements should be read in conjunction with the Company's Annual Report on Form 10-K for the year ended December 31, 2022. The results of operations for the six months ended June 30, 2023, are not necessarily indicative of the future results that may be attained for the entire year or other interim periods.

In the opinion of management, all necessary adjustments have been reflected to present fairly the financial position, results of operations, and cash flows for the reporting periods presented. Intercompany transactions and balances have been eliminated in consolidation. Assets under administration or assets under management that the Company holds or manages in a fiduciary or agency capacity for customers are not included in the Condensed Consolidated Financial Statements.

Use of Estimates

The preparation of the Condensed Consolidated Financial Statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the Condensed Consolidated Financial Statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Accounting Standards Adopted in the Current Period

ASU No. 2022-02—Financial Instruments—Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures

In March 2022, the FASB issued ASU No. 2022-02, which eliminates the accounting guidance for TDRs by creditors in Subtopic 310-40, Receivables—Troubled Debt Restructurings by Creditors, while enhancing disclosure requirements for certain loan refinancings and restructurings by creditors when a borrower is experiencing financial difficulty. Specifically, rather than applying the recognition and measurement guidance for TDRs, an entity must apply the loan refinancing and restructuring guidance in paragraphs 310-20-35-9 through 35-11 to determine whether a modification results in a new loan or a continuation of an existing loan. In addition, the Update requires that an entity disclose current-period gross write-offs by year of origination for financing receivables and net investments in leases within the scope of Subtopic 326-20, Financial Instruments—Credit Losses—Measured at Amortized Cost in the vintage disclosures required by paragraph 326-20-50-6.

Modifications to borrowers experiencing financial difficulty include principal forgiveness, interest rate reductions, payment delays, term extensions, or combinations thereof. Expected losses or recoveries on loans where modifications have been granted to borrowers experiencing financial difficulty have been factored into the ACL on loans and leases. Upon adoption of ASU 2022-02, the Company is no longer required to use a discounted cash flow (or reconcilable) method to measure the ACL resulting from a modification with a borrower experiencing financial difficulty. Accordingly, the Company now applies the same credit loss methodology it uses for similar loans that were not modified.

The Company adopted the Update on January 1, 2023. The Company elected the option to apply the modified retrospective transition method related to the recognition and measurement of TDRs, which resulted in a $5.9 million increase to the Allowance for Credit Losses on Loans and Leases and a $1.7 million decrease to Deferred Tax Assets, net, with a corresponding $4.2 million cumulative-effect adjustment to retained earnings as of the adoption date. The enhanced disclosure requirements provided for by the Update were adopted on a prospective basis. Reporting periods prior to the adoption of the Update are accounted for and presented in accordance with the applicable GAAP.

Refer to Note 4: Loans and Leases for additional information regarding modifications granted to borrowers experiencing financial difficulty.

42

ASU No. 2022-01—Derivatives and Hedging (Topic 815): Fair Value Hedging—Portfolio Layer Method

In March 2022, the FASB issued ASU No. 2022-01—Derivatives and Hedging (Topic 815): Fair Value Hedging—Portfolio Layer Method, which expands the current last-of-layer method of hedge accounting that permits only one hedged layer to allow multiple hedged layers of a single closed portfolio. To reflect that expansion, the last-of-layer method is renamed the portfolio layer method. Additionally, the amendments in this Update: (i) expand the scope of the portfolio layer method to include non-prepayable assets; (ii) specify eligible hedging instruments in a single-layer hedge; (iii) provide additional guidance on the accounting for and disclosure of hedge basis adjustments; and (iv) specify how hedge basis adjustments should be considered when determining credit losses for the assets included in the closed portfolio. An entity may also reclassify debt securities classified in the held-to-maturity category at the date of adoption to the available-for-sale category only if the entity applies portfolio layer method hedging to one or more closed portfolios that include those debt securities within a 30-day period.

The Company adopted the Update on January 1, 2023 on a prospective basis. The adoption of this guidance did not have a material impact on the Company's Consolidated Financial Statements. The entity did not reclassify any debt securities from the held-to-maturity category to the available-for-sale category as permitted upon adoption.

ASU No. 2021-08—Business Combinations (Topic 805)—Accounting for Contract Assets and Contract Liabilities from Contracts with Customers

In October 2021, the FASB issued ASU No. 2021-08—Business Combinations (Topic 805)—Accounting for Contract Assets and Contract Liabilities from Contracts with Customers, which requires that an acquirer recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with Topic 606, Revenue from Contracts with Customers. At the acquisition date, an acquirer should account for the related revenue contracts in accordance with Topic 606 as if it had originated the contracts.

The Company adopted the Update on January 1, 2023 on a prospective basis. The adoption of this guidance did not have a material impact on the Company's Consolidated Financial Statements.

Relevant Accounting Standards Issued But Not Yet Adopted

ASU No. 2023-02—Investments—Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method (a consensus of the Emerging Issues Task Force)

In March 2023, the FASB issued ASU No. 2023-02—Investments—Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method (a consensus of the Emerging Issues Task Force), which permits reporting entities to elect to account for their tax equity investments, regardless of the program from which the income tax credits are received, using the proportional amortization method if certain conditions are met. A reporting entity may make an accounting policy election to apply the proportional amortization method in accordance with paragraph 323-740-25-4 on a tax-credit-program-by-tax-credit-program basis rather than electing to apply the proportional amortization method at the reporting entity level or to individual investments.

A reporting entity that applies the proportional amortization method to qualifying tax equity investments must account for the receipt of the investment tax credits using the flow-through method under Topic 740, Income Taxes, even if the entity applies the deferral method for other investment tax credit received. The amendments also remove certain guidance for Qualified Affordable Housing Project Investments, require the application of the delayed equity contribution guidance to all tax equity investments, and require specific disclosures that must be applied to all investments that generate income tax credits and other income tax benefits from a tax credit program for which the entity has elected to apply the proportional amortization method in accordance with Subtopic 323-740.

The Update is effective for fiscal years beginning after December 15, 2023, and interim periods within those fiscal years, with early adoption permitted. The amendments generally must be applied on either a modified retrospective or retrospective basis with a cumulative-effect adjustment to retained earnings reflecting the difference between the previous method used to account for the tax equity investment and the application of the proportional amortization method since the investment was entered into. The adoption of this guidance is not expected to have a material impact on the Consolidated Financial Statements as the Company's investments in tax credit structures are currently limited to LIHTC investments, which are already being accounted for using the proportional amortization method.

43

ASU No. 2023-01—Leases (Topic 842): Common Control Arrangements

In March 2023, the FASB issued ASU No. 2023-01—Leases (Topic 842): Common Control Arrangements, which requires that leasehold improvements associated with leases between entities under common control be: (i) amortized by the lessee over the useful live of the leasehold improvements to the common control group (regardless of the lease term) as long as the lessee controls the use of the underlying asset (the leased asset) through a lease; however, if the lessor obtained the right to control the use of the underlying asset through a lease with another entity not within the same common control group, the amortization period may not exceed the amortization period of the common control group; and (ii) accounted for as a transfer between entities under common control through an adjustment to equity, if, and when, the lessee no longer controls the use of the underlying asset. Additionally, those leasehold improvements are subject to the impairment guidance in Topic 360, Property, Plant, and Equipment.

The Update is effective for fiscal years beginning after December 15, 2023, and interim periods within those fiscal years, with early adoption permitted. The amendments either may be applied prospectively to all new and existing leasehold improvements recognized on or after the adoption date with any remaining unamortized balance of existing leasehold improvements amortized over their remaining useful life to the common control group determined at that date; or retrospectively to the beginning of the period in which the entity first applied Topic 842, with any leasehold improvements that otherwise would not have been amortized or impaired recognized through a cumulative-effect adjustment to the opening balance of retained earnings at the beginning of the earliest period presented in accordance with Topic 842. The Company is in the early assessment stages of evaluating the amendments and the impact of adoption on its Consolidated Financial Statements.

ASU No. 2022-03—Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions

In June 2022, the FASB issued ASU No. 2022-03—Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions, which clarifies that a contractual restriction on the sale of an equity security is not considered part of the unit of account of the equity security, and therefore, is not considered in measuring fair value. The amendments also clarify that an entity cannot, as a separate unit of account, recognize and measure a contractual sale restriction, and requires the following disclosures for equity securities subject to contractual sale restrictions: (i) the fair value of equity securities subject to contractual sale restrictions reflected on the balance sheet; (ii) the nature and remaining duration of the restriction(s); and (iii) the circumstances that could cause a lapse in the restriction(s).

The Update is effective for fiscal years beginning after December 15, 2023, and interim periods within those fiscal years, with early adoption permitted. For all entities except investment companies, the amendments should be applied prospectively with any adjustments from the adoption of the amendments recognized in earnings and disclosed on the date of adoption. The adoption of this guidance is not expected to have a material impact on the Consolidated Financial Statements and disclosures. The Company does not currently consider contractual restrictions on the sale of an equity security in measuring fair value.

Note 2: Mergers and Acquisitions

interLINK Acquisition

On January 11, 2023, Webster acquired 100% ownership of interLINK from StoneCastle Partners LLC. interLINK is a technology-enabled deposit management platform that administers over $9 billion of deposits from FDIC-insured cash sweep programs between banks and broker/dealers and clearing firms. The acquisition provides the Company with access to a unique source of core deposit funding and scalable liquidity and adds another technology-enabled channel to its already differentiated, omnichannel deposit gathering capabilities.

The total purchase price of the acquisition was $174.6 million, which included cash paid of $158.6 million and $16.0 million of contingent consideration measured at fair value. The contingent consideration is payable in cash upon the achievement of discrete customer and deposit growth events within three years of the acquisition date. Additional information regarding the determination of fair value for contingent consideration liabilities can be found within Note 14: Fair Value Measurements.

The transaction has been accounted for as a business combination, and resulted in the addition of $31.4 million in net assets measured at fair value, which primarily comprised $36.0 million of broker dealer relationship intangible assets, $6.0 million of developed technology, a $4.0 million non-competition agreement intangible asset, and $15.9 million of royalty liabilities. The $143.2 million of goodwill recognized is deductible for tax purposes. The Company's valuations of the assets acquired and liabilities assumed in the interLINK acquisition were considered final as of June 30, 2023.

Bend Financial, Inc. Acquisition

On February 18, 2022, Webster acquired 100% of the equity interests of Bend, a cloud-based platform solution provider for HSAs, in exchange for cash of $55.3 million. The transaction was accounted for as a business combination, and resulted in the addition of $19.6 million in net assets measured at fair value, which primarily comprised $15.9 million of internal use software and a $3.0 million customer relationship intangible asset. The Company's valuations of the assets acquired and liabilities assumed in the Bend acquisition were considered final as of March 31, 2023.

Merger with Sterling Bancorp

On January 31, 2022, Webster completed its merger with Sterling. The transaction was accounted for as a business combination. Accordingly, the purchase price was allocated to the assets acquired and liabilities assumed based on their fair values as of the merger effective date. The determination of fair value requires management to make estimates about discount rates, future expected cash flows, market conditions, and other future events that are highly subjective in nature and are subject to change. Fair value estimates of the assets acquired and liabilities assumed were subject to adjustment during the one-year measurement period following the closing of the merger if new information was obtained about facts and circumstances that existed as of the merger effective date that, if known, would have affected the measurement of the amounts recognized as of that date. Measurement period adjustments made during the first quarter of 2023 totaled a net $25.6 million, which pertained to other assets and other liabilities and their related deferred tax impact. The Company's valuations of the assets acquired and liabilities assumed in the merger with Sterling were considered final as of March 31, 2023.

The $18.5 million increase in gross unrealized losses from December 31, 2022, to June 30, 2023, is primarily due to higher market rates. The Company assesses each available-for-sale security that is in an unrealized loss position to determine whether the decline in fair value below the amortized cost basis is a result from a credit loss or other factors. At both June 30, 2023, and December 31, 2022, no ACL was recorded on available-for-sale securities as each of the securities in the Company's portfolio are investment grade, current as to principal and interest, and their price changes are consistent with interest and credit spreads when adjusting for convexity, rating, and industry differences.

At June 30, 2023, based on current market conditions and the Company's current targeted balance sheet composition strategy, the Company intends to hold its available-for-sale securities with unrealized loss positions through the anticipated recovery period, and it is more-likely-than-not that the Company will not have to sell these available-for-sale securities before the recovery of the entire amortized cost basis. The issuers of these available-for-sale securities have not, to the Company’s knowledge, established any cause for default. Market prices are expected to approach par as the securities approach maturity.

Contractual Maturities

The following table summarizes the amortized cost and fair value of available-for-sale securities by contractual maturity:

	At June 30, 2023
(In thousands)	Amortized Cost		Fair Value
Maturing within 1 year	$	33,337	$	33,164
After 1 year through 5 years	1,040,297		978,096
After 5 through 10 years	1,401,731		1,277,563
After 10 years	6,166,939		5,470,518
Total available-for-sale securities	$	8,642,304	$	7,759,341

Available-for-sale securities that are not due at a single maturity date have been categorized based on the maturity date of the underlying collateral. Actual principal cash flows may differ from this categorization as borrowers have the right to repay their obligations with or without prepayment penalties.

Sales of Available-for Sale Securities

During the three and six months ended June 30, 2023, the Company sold U.S. Treasury notes, Corporate debt securities, and Municipal bonds and notes classified as available-for-sale for proceeds of $2.9 million and $398.3 million, respectively, which resulted in gross realized losses of $48 thousand and $20.5 million, respectively. Because $3.8 million of the total loss recognized for the six months ended June 30, 2023, was attributed to a decline in credit quality, those portions of the charges have been included in the Provision for credit losses on the accompanying Condensed Consolidated Statements of Income. There were no sales of available-for-sale securities during the three and six months ended June 30, 2022.

(1)Accrued interest receivable on held-to-maturity securities of $24.5 million and $24.2 million at June 30, 2023, and December 31, 2022, respectively, is excluded from amortized cost and is included in Accrued interest receivable and other assets on the accompanying Condensed Consolidated Balance Sheets.

An ACL on held-to-maturity securities is recorded for certain Municipal bonds and notes to account for expected lifetime credit losses. Agency securities represent obligations issued by a U.S. government-sponsored enterprise or other federally-related entity and are either explicitly or implicitly guaranteed and therefore, assumed to be zero loss. Held-to-maturity securities with gross unrealized losses and no ACL are considered to be high credit quality, and therefore, zero credit loss has been recorded.

The following table summarizes the activity in the ACL on held-to-maturity securities:

Held-to-maturity securities that are not due at a single maturity date have been categorized based on the maturity date of the underlying collateral. Actual principal cash flows may differ from this categorization as borrowers have the right to prepay their obligations with or without prepayment penalties.

Credit Quality Information

The Company monitors the credit quality of held-to-maturity securities through credit ratings provided by Standard & Poor's Rating Services, Moody's Investor Services, Fitch Ratings, Inc., Kroll Bond Rating Agency, or DBRS Inc. Credit ratings express opinions about the credit quality of a security, and are updated at each quarter end. Investment grade securities are rated BBB- or higher by S&P, or Baa3 or higher by Moody's, and are generally considered by the rating agencies and market participants to be of low credit risk. Conversely, securities rated below investment grade, which are labeled as speculative grade by the rating agencies, are considered to have distinctively higher credit risk than investment grade securities. There were no speculative grade held-to-maturity securities at June 30, 2023, or December 31, 2022. Held-to-maturity securities that are not rated are collateralized with U.S. Treasury obligations.

Credit Quality Indicators

To measure credit risk for the commercial portfolio, the Company employs a dual grade credit risk grading system for estimating the PD and LGD. The credit risk grade system assigns a rating to each borrower and to the facility, which together form a Composite Credit Risk Profile. The credit risk grade system categorizes borrowers by common financial characteristics that measure the credit strength of borrowers and facilities by common structural characteristics. The Composite Credit Risk Profile has ten grades, with each grade corresponding to a progressively greater risk of loss. Grades (1) to (6) are considered pass ratings, and grades (7) to (10) are considered criticized, as defined by the regulatory agencies. A (7) "Special Mention" rating has a potential weakness that, if left uncorrected, may result in deterioration of the repayment prospects for the asset. A (8) "Substandard" rating has a well-defined weakness that jeopardizes the full repayment of the debt. A (9) "Doubtful" rating has all of the same weaknesses as a substandard asset with the added characteristic that the weakness makes collection or liquidation in full given current facts, conditions, and values improbable. Assets classified as a (10) "Loss" rating are considered uncollectible and are charged-off. Risk ratings, which are assigned to differentiate risk within the portfolio, are reviewed on an ongoing basis and revised to reflect changes in a borrower's current financial position and outlook, risk profile, and the related collateral and structural position. Loan officers review updated financial information or other loan factors on at least an annual basis for all pass rated loans to assess the accuracy of the risk grade. Criticized loans undergo more frequent reviews and enhanced monitoring.

To measure credit risk for the consumer portfolio, the most relevant credit characteristic is the FICO score, which is a widely used credit scoring system that ranges from 300 to 850. A lower FICO score is indicative of higher credit risk and a higher FICO score is indicative of lower credit risk. FICO scores are updated on at least a quarterly basis.

Collateral Dependent Loans and Leases

A loan or lease is considered collateral dependent when the borrower is experiencing financial difficulty and repayment is substantially expected to be provided through the operation or sale of collateral. At June 30, 2023, and December 31, 2022, the carrying amount of collateral dependent commercial loans and leases totaled $31.9 million and $43.8 million, respectively, and the carrying amount of collateral dependent consumer loans totaled $39.2 million and $45.2 million, respectively. Commercial non-mortgage, asset-based, and equipment financing loans and leases are generally secured by machinery and equipment, inventory, receivables, or other non-real estate assets, whereas commercial real estate, multi-family, residential, home equity, and other consumer loans are secured by real estate. The ACL for collateral dependent loans and leases is individually assessed based on the fair value of the collateral less costs to sell. At June 30, 2023, and December 31, 2022, the collateral value associated with collateral dependent loans and leases totaled $91.8 million and $108.0 million, respectively.

Modifications for Borrowers Experiencing Financial Difficulty

On January 1, 2023, the Company adopted ASU 2022-02, which eliminates the accounting guidance for TDRs and enhances the disclosure requirements for certain loan modifications when a borrower is experiencing financial difficulty. For a description of the Company's accounting policies related to the accounting and reporting of TDRs, for which comparative period information is presented, refer to Note 1: Summary of Significant Accounting Policies of the Company's Annual Report on Form 10-K for the year ended December 31, 2022.

In certain circumstances, the Company enters into agreements to modify the terms of loans to borrowers experiencing financial difficulty. A variety of solutions are offered to borrowers experiencing financial difficulty, including loan modifications that may result in principal forgiveness, interest rate reductions, payment delays, term extension, or a combination thereof. The following is a description of each of these types of modifications:

•Principal forgiveness – The outstanding principal balance of a loan may be reduced by a specified amount. Principal forgiveness may occur voluntarily as part of a negotiated agreement with a borrower, or involuntarily through a bankruptcy proceeding.

•Interest rate reductions – Includes modifications where the contractual interest rate of the loan has been reduced.

•Payment delays – Deferral arrangements which allow borrowers to delay a scheduled loan payment to a later date. Deferred loan payments do not affect the original contractual terms of the loan. Modifications that result in only an insignificant payment delay are not disclosed. The Company considers that a three month or less payment delay generally would be considered insignificant.

•Term extensions – Extensions of the original contractual maturity date of the loan.

•Combination – Combination includes loans that have undergone more than one of the above loan modification types.

Significant judgment is required to determine if a borrower is experiencing financial difficulty. These considerations vary by portfolio class. The Company has identified modifications to borrowers experiencing financial difficulty that are included in its disclosures as follows:

•Commercial: The Company evaluates modifications of loans to commercial borrowers that are rated substandard or worse, and includes the modifications in its disclosures to the extent that the modification is considered
other-than-insignificant.

•Consumer: The Company evaluates modifications of loans to consumer borrowers subject to its loss mitigation program and includes them in its disclosures to the extent that the modification is considered other-than-insignificant.

Note 10: Regulatory Capital and Restrictions

Capital Requirements

The Holding Company and the Bank are subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory actions by regulators that could have a direct material effect on the Company’s financial statements. Under capital adequacy guidelines and/or the regulatory framework for prompt corrective action (such provisions apply to the Bank only), both the Holding 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 regulatory directives. Capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors.

Quantitative measures established by the Basel III Capital Rules to ensure capital adequacy require the Company to maintain minimum ratios of CET1 capital to total risk-weighted assets (CET1 risk-based capital), Tier 1 capital to total risk-weighted assets (Tier 1 risk-based capital), Total capital to total risk-weighted assets (Total risk-based capital), and Tier 1 capital to average tangible assets (Tier 1 leverage capital), as defined in the regulations. CET1 capital consists of common stockholders’ equity less deductions for goodwill and other intangible assets, and certain deferred tax adjustments. Upon adoption of the Basel III Capital Rules, the Company elected to opt-out of the requirement to include certain components of AOCI in CET1 capital. Tier 1 capital consists of CET1 capital plus preferred stock. Total capital consists of Tier 1 capital and Tier 2 capital, as defined in the regulations. Tier 2 capital includes permissible portions of subordinated debt and the ACL.

At June 30, 2023, and December 31, 2022, both the Holding Company and the Bank were classified as well-capitalized. Management believes that no events or changes have occurred subsequent to year-end that would change this designation.

The following tables provides information on the capital ratios for the Holding Company and the Bank:

	At June 30, 2023
	Actual (1)				Minimum Requirement				Well Capitalized

(1)In accordance with regulatory capital rules, the Company elected an option to delay the estimated impact of the adoption of CECL on its regulatory capital over a two-year deferral period, which ended on January 1, 2022, and a subsequent three-year transition period ending on December 31, 2024. During the three-year transition period, regulatory capital ratios will phase out the aggregate amount of the regulatory capital benefit provided from the delayed CECL adoption in the initial two years. For 2022, 2023, and 2024, the Company is allowed 75%, 50%, and 25%, respectively, of the regulatory capital benefit as of December 31, 2021, with full absorption occurring in 2025.

Dividend Restrictions

The Holding Company is dependent upon dividends from the Bank to provide funds for the payment of dividends to stockholders and for other cash requirements. Dividends paid by the Bank are subject to various federal and state regulatory limitations. Express approval by the OCC is required if the effect of dividends declared would cause the regulatory capital of the Bank to fall below specified minimum levels or if the amount would exceed net income for that year combined with undistributed net income for the preceding two years. The Bank paid the Holding Company $100.0 million and $250.0 million in dividends during the three and six months ended June 30, 2023, respectively, and $125.0 million in dividends during the three and six months ended June 30, 2022, for which no express approval from the OCC was required.

Cash Restrictions

The Bank is required under Federal Reserve regulations to maintain cash reserve balances in the form of vault cash or deposits held at a FRB to ensure that it is able to meet customer demands. The reserve requirement ratio is subject to adjustment as economic conditions warrant. Effective March 26, 2020, the Federal Reserve reset the requirement to zero in order to address liquidity concerns resulting from the COVID-19 pandemic. Pursuant to this action, the Bank has not been required to hold cash reserve balances since that date.

Note 11: Variable Interest Entities

The Company has an investment interest in the following entities that each meet the definition of a variable interest entity. Information regarding the Company's consolidation of variable interest entities can be found within Note 1: Summary of Significant Accounting Policies in the Consolidated Financial Statements contained in Part II - Item 8. Financial Statements and Supplementary Data of the Company's Annual Report on Form 10-K for the year ended December 31, 2022.

Consolidated

Rabbi Trusts. The Company established a Rabbi Trust to meet its obligations due under the Webster Bank Deferred Compensation Plan for Directors and Officers and to mitigate expense volatility. The funding of the Rabbi Trust and the discontinuation of the Webster Bank Deferred Compensation Plan for Directors and Officers occurred during 2012. In connection with the Sterling merger in 2022, the Company acquired assets held in a separate Rabbi Trust that had been previously established to fund obligations due under the Greater New York Savings Bank Directors' Retirement Plan.

Investments held in the Rabbi Trusts consist primarily of mutual funds that invest in equity and fixed income securities. The Company is considered the primary beneficiary of these Rabbi Trusts as it has the power to direct the activities of the Rabbi Trusts that most significantly impact its economic performance and it has the obligation to absorb losses and/or the right to receive benefits of the Rabbi Trusts that could potentially be significant.

The Rabbi Trusts' assets are included in Accrued interest receivable and other assets on the accompanying Condensed Consolidated Balance Sheets. Investment earnings and any changes in fair value are included in Other income on the accompanying Condensed Consolidated Statements of Income. Additional information regarding the Rabbi Trusts' investments can be found within Note 14: Fair Value Measurements.

Non-Consolidated

Low-Income Housing Tax Credit Investments. The Company makes non-marketable equity investments in entities that sponsor affordable housing and other community development projects that qualify for the LIHTC Program pursuant to Section 42 of the Internal Revenue Code. The purpose of these investments is not only to assist the Bank in meeting its responsibilities under the CRA, but also to provide a return, primarily through the realization of tax benefits. While the Company's investment in an entity may exceed 50% of its outstanding equity interests, the entity is not consolidated as the Company is not the primary beneficiary. The Company has determined that it is not the primary beneficiary due to its inability to direct the activities that most significantly impact economic performance and the Company does not have the obligation to absorb losses and/or the right to receive benefits. The Company applies the proportional amortization method to subsequently measure its investments in qualified affordable housing projects.

The following table summarizes the Company's LIHTC investments and related unfunded commitments:

(In thousands)	June 30, 2023		December 31, 2022
Gross investment in LIHTC investments	$	868,459	$	797,453
Accumulated amortization	(105,719)		(69,424)
Net investment in LIHTC investments	$	762,740	$	728,029
Unfunded commitments for LIHTC investments	$	366,869	$	335,959

68

The aggregate carrying value of the Company's LIHTC investments is included in Accrued interest receivable and other assets on the accompanying Condensed Consolidated Balance Sheets, and represents the Company's maximum exposure to loss. The related unfunded commitments are included in Accrued expenses and other liabilities on the accompanying Condensed Consolidated Balance Sheets. There were $68.2 million and $76.7 million of net commitments approved to fund LIHTC investments during the six months ended June 30, 2023, and 2022, respectively.

Webster Statutory Trust. The Company owns all the outstanding common stock of Webster Statutory Trust, a financial vehicle that has issued, and in the future may issue, trust preferred securities. The Company is not the primary beneficiary of Webster Statutory Trust. Webster Statutory Trust's only assets are junior subordinated debentures that are issued by the Company, which were acquired using the proceeds from the issuance of trust preferred securities and common stock. The junior subordinated debentures are included in Long-term debt on the accompanying Condensed Consolidated Balance Sheets, and the related interest expense is included in Long-term debt on the accompanying Condensed Consolidated Statements of Income. Additional information regarding these junior subordinated debentures can be found within Note 8: Borrowings.

Other Non-Marketable Investments. The Company invests in alternative investments comprising interests in non-public entities that cannot be redeemed since the underlying equity is distributed as the investment is liquidated. The ultimate timing and amount of these distributions cannot be predicted with reasonable certainty. For each of these alternative investments that is classified as a variable interest entity, the Company has determined that it is not the primary beneficiary due to its inability to direct the activities that most significantly impact economic performance. The aggregate carrying value of the Company's other non-marketable investments was $170.1 million and $144.9 million at June 30, 2023, and December 31, 2022, respectively, which is included in Accrued interest receivable and other assets on the accompanying Condensed Consolidated Balance Sheets, and its maximum exposure to loss, including unfunded commitments, was $293.9 million and $243.9 million, respectively. Additional information regarding the fair value of other non-marketable investments can be found within
Note 14: Fair Value Measurements.

Note 12: Earnings Per Common Share

The following table summarizes the calculation of basic and diluted earnings per common share:

	Three months ended June 30,				Six months ended June 30,
(In thousands, except per share data)	2023		2022		2023		2022
Net income	$	234,968	$	182,311	$	455,972	$	165,564
Less: Preferred stock dividends	4,162		4,163		8,325		7,594
Net income available to common stockholders	230,806		178,148		447,647		157,970
Less: Earnings allocated to participating securities	2,235		1,718		4,073		1,456
Earnings applicable to common stockholders	$	228,571	$	176,430	$	443,574	$	156,514
Weighted-average common shares outstanding - basic	172,739		175,845		172,752		161,698
Add: Effect of dilutive stock options and restricted stock	64		50		87		87
Weighted-average common shares outstanding - diluted	172,803		175,895		172,839		161,785
Basic earnings per common share	$	1.32	$	1.00	$	2.57	$	0.97
Diluted earnings per common share	1.32		1.00		2.57		0.97

Earnings per common share is calculated under the two-class method in which all earnings (distributed and undistributed) are allocated to common stock and participating securities based on their respective rights to receive dividends. The Company may grant restricted stock, restricted stock units, non-qualified stock options, incentive stock options, or stock appreciation rights to certain employees and directors under its stock-based compensation programs, which entitle recipients to receive
non-forfeitable dividends during the vesting period on a basis equivalent to the dividends paid to holders of common stock. These unvested awards meet the definition of participating securities.

Potential common shares from performance-based restricted stock that were not included in the computation of dilutive earnings per common share because they were anti-dilutive under the treasury stock method were 263,674 and 174,840 for the three and six months ended June 30, 2023, respectively, and 379,308 and 298,617 for the three and six months ended
June 30, 2022, respectively.

Note 13: Derivative Financial Instruments

Derivative Positions and Offsetting

Derivatives Designated as Hedging Instruments. Interest rate swaps allow the Company to change the fixed or variable nature of an interest rate without the exchange of the underlying notional amount. Certain pay fixed/receive variable interest rate swaps are designated as cash flow hedges to effectively convert variable-rate debt into fixed-rate debt, whereas certain receive fixed/pay variable interest rate swaps are designated as fair value hedges to effectively convert fixed-rate long-term debt into variable-rate debt. Certain purchased options are also designated as cash flow hedges. Purchased options allow the Company to limit the potential adverse impact of variable interest rates by establishing a cap rate or floor rate in exchange for an upfront premium. The purchased options designated as cash flow hedges represent interest rate caps where payment is received from the counterparty if interest rates rise above the cap rate, and interest rate floors where payment is received from the counterparty when interest rates fall below the floor rate.

Derivatives Not Designated as Hedging Instruments. The Company also enters into other derivative transactions to manage economic risks, but does not designate the instruments in hedge relationships. In addition, the Company enters into derivative contracts to accommodate customer needs. Derivative contracts with customers are offset with dealer counterparty transactions structured with matching terms to ensure minimal impact on earnings.

Time-value premiums, which are amortized on a straight-line basis, are excluded from the assessment of hedge effectiveness for purchased options designated as cash flow hedges. At June 30, 2023, the remaining unamortized balance of time-value premiums was $1.4 million. Over the next twelve months, an estimated decrease to interest income of $34.4 million will be reclassified from AOCI relating to cash flow hedge gain/loss, and an estimated increase to interest expense of $0.2 million will be reclassified from AOCI relating to cash flow hedge terminations. At June 30, 2023, the remaining unamortized loss on terminated cash flow hedges was $0.2 million. The maximum length of time over which forecasted transactions are hedged is 4.7 years. Additional information regarding cash flow hedge activity impacting AOCI and the related amounts reclassified to net income can be found within Note 9: Accumulated Other Comprehensive (Loss) Income, Net of Tax.

Derivative Exposure. At June 30, 2023, the Company had $4.6 million in initial margin collateral posted at clearing houses. In addition, $315.2 million of cash collateral received is included in Cash and due from banks on the accompanying Condensed Consolidated Balance Sheets. The Company regularly evaluates the credit risk of its derivative customers, taking into account the likelihood of default, net exposures, and remaining contractual life, among other related factors. Credit risk exposure is mitigated as transactions with customers are generally secured by the same collateral of the underlying transactions. Current net credit exposure relating to derivatives with the Bank's customers was $5.8 million at June 30, 2023. In addition, the Company monitors potential future exposure, representing its best estimate of exposure to remaining contractual maturity. The potential future exposure relating to derivatives with the Bank's customers totaled $101.8 million at June 30, 2023. The Company has incorporated a valuation adjustment to reflect non-performance risk in the fair value measurement of its derivatives, which totaled $6.6 million and $8.4 million at June 30, 2023, and December 31, 2022, respectively. Various factors impact changes in the valuation adjustment over time, such as changes in the credit spreads of the contracted parties, and changes in market rates and volatilities, which affect the total expected exposure of the derivative instruments.

Note 14: Fair Value Measurements

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The determination of fair value may require the use of estimates when quoted market prices are not available. Fair value estimates made at a specific point in time are based on management’s judgments regarding future expected losses, current economic conditions, the risk characteristics of each financial instrument, and other subjective factors that cannot be determined with precision.

The framework for measuring fair value provides a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. The three levels within the fair value hierarchy are as follows:

•Level 1: Inputs to the valuation methodology are unadjusted quoted prices for identical assets or liabilities in active markets that the Company has the ability to access at the measurement date.

•Level 2: Inputs to the valuation methodology include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in inactive markets, inputs other than quoted prices that are observable for the asset or liability (i.e., interest rates, rate volatility, prepayment speeds, and credit ratings), or inputs that are derived principally from or corroborated by market data, correlation, or other means.

•Level 3: Inputs to the valuation methodology are unobservable and significant to the fair value measurement. This includes certain pricing models or other similar techniques that require significant management judgment or estimation.

Assets and Liabilities Measured at Fair Value on a Recurring Basis

Available-for-Sale Securities. When unadjusted quoted prices are available in an active market, the Company classifies its available-for-sale investment securities within Level 1 of the fair value hierarchy. U.S. Treasury notes have a readily determinable fair value, and accordingly, are classified within Level 1 of the fair value hierarchy.

When quoted market prices are not available, the Company employs an independent pricing service that utilizes matrix pricing to calculate fair value. These fair value measurements consider observable data, such as dealer quotes, market spreads, cash flows, yield curves, live trading levels, trade execution data, market consensus prepayments speeds, credit information, and the respective terms and conditions for debt instruments. Management maintains procedures to monitor the pricing service's results and has a process in place to challenge their valuations and methodologies that appear unusual or unexpected. Government agency debentures, Municipal bonds and notes, Agency CMO, Agency MBS, Agency CMBS, CMBS, CLO, Corporate debt, Private label MBS, and Other available-for-sale securities are classified within Level 2 of the fair value hierarchy.

Derivative Instruments. The fair values presented for derivative instruments include any accrued interest. Foreign exchange contracts are valued based on unadjusted quoted prices in active markets, and accordingly, are classified within Level 1 of the fair value hierarchy. Except for mortgage banking derivatives, all other derivative instruments are valued using third-party valuation software, which considers the present value of cash flows discounted using observable forward rate assumptions. The resulting fair value is then validated against valuations performed by independent third parties. These derivative instruments are classified within Level 2 of the fair value hierarchy.

72

Mortgage Banking Derivatives. The Company uses forward sales of mortgage loans and mortgage-backed securities to manage the risk of loss associated with its mortgage loan commitments and mortgage loans held for sale. Prior to closing and funding certain single-family residential mortgage loans, an interest rate lock commitment is generally extended to the borrower. During this in-between time period, the Company is subject to the risk that market interest rates may change. If rates rise, investors generally will pay less to purchase mortgage loans, which would result in a reduction in the gain on sale of the loans, or possibly a loss. In an effort to mitigate this risk, forward delivery sales commitments are established in which the Company agrees to either deliver whole mortgage loans to various investors or issue mortgage-backed securities. The fair value of mortgage banking derivatives is determined based on current market prices for similar assets in the secondary market. Accordingly, mortgage banking derivatives are classified within Level 2 of the fair value hierarchy.

Originated Loans Held For Sale. The Company has elected to measure originated loans held for sale at fair value under the fair value option per ASC Topic 825, Financial Instruments. Electing to measure originated loans held for sale at fair value reduces certain timing differences and better reflects the price the Company would expect to receive from the sale of these loans. The fair value of originated loans held for sale is based on quoted market prices of similar loans sold in conjunction with securitization transactions. Accordingly, originated loans held for sale are classified within Level 2 of the fair value hierarchy.

The following table compares the fair value to the unpaid principal balance of originated loans held for sale:

	At June 30, 2023						At December 31, 2022
(In thousands)	Fair Value		Unpaid Principal Balance		Difference		Fair Value		Unpaid Principal Balance		Difference
Originated loans held for sale	$	1,800	$	1,322	$	478	$	1,991	$	1,631	$	360

Rabbi Trust Investments. Investments held in each of the Company's Rabbi Trusts consist primarily of mutual funds that invest in equity and fixed income securities. Shares of these mutual funds are valued based on the NAV as reported by the trustee of the funds, which represents quoted prices in active markets. The Company has elected to measure the Rabbi Trusts' investments at fair value. Accordingly, the Rabbi Trusts' investments are classified within Level 1 of the fair value hierarchy. At June 30, 2023, and December 31, 2022, the total cost basis of the investments held in the Rabbi Trusts was $10.2 million and $10.0 million, respectively.

Alternative Investments. Equity investments have a readily determinable fair value when unadjusted quoted prices are available in an active market for identical assets. Accordingly, these alternative investments are classified within Level 1 of the fair value hierarchy. At June 30, 2023, and December 31, 2022, equity investments with a readily determinable fair value had a total carrying amount of $0.6 million and $0.4 million, respectively, with no remaining unfunded commitment. During the three and six months ended June 30, 2023, there were total write-ups in fair value of $0.1 million and $0.2 million, respectively, associated with these alternative investments.

Equity investments that do not have a readily determinable fair value may qualify for the NAV practical expedient if they meet certain requirements. The Company's alternative investments measured at NAV consist of investments in non-public entities that cannot be redeemed since investments are distributed as the underlying equity is liquidated. Alternative investments measured at NAV are not classified within the fair value hierarchy. At June 30, 2023, and December 31, 2022, these alternative investments had a total carrying amount of $28.5 million and $89.2 million, respectively, and a remaining unfunded commitment of $27.0 million and $82.7 million, respectively.

Contingent Consideration. The Company recorded $16.0 million of contingent consideration at fair value related to two earn-out agreements associated with the acquisition of interLINK on January 11, 2023. The terms of the purchase agreement specified that the seller would receive earn-outs based on the ability of the Company to: (i) re-sign the existing broker dealers under contract, and (ii) generate $2.5 billion in new broker dealer deposit programs within three years of the acquisition date. The estimated fair values of the contingent consideration liabilities are measured on a recurring basis and determined using an income approach considering management’s evaluation of the probability of achievement, forecasted achievement date (payment term), and a discount rate equivalent to the counterparty cost of debt. These significant inputs, which are the responsibility of management and were initially calculated with the assistance of a third-party valuation specialist, are not observable and accordingly, are classified within Level 3 of the fair value hierarchy.

The following table summarizes the unobservable inputs used to derive the estimated fair value of the Company’s contingent consideration liabilities at June 30, 2023 (dollars in thousands):

Agreement	Maximum Amount		Probability of Achievement	Payment Term (in years)	Discount Rate	Fair Value
(i) Re-sign broker dealers	$	4,826	99.0 %	0.22	5.50 %	$	4,798
(ii) Deposit program growth	$	12,500	100.0 %	1.97	5.50 %	$	11,241

Contingent consideration liabilities are included within Accrued expenses and other liabilities on the accompanying Condensed Consolidated Balance Sheets. Any fair value adjustments to contingent consideration liabilities are included in Other expense on the accompanying Condensed Consolidated Statements of Income.

Assets Measured at Fair Value on a Non-Recurring Basis

The Company measures certain assets at fair value on a non-recurring basis. The following is a description of the valuation methodologies used for assets measured at fair value on a non-recurring basis.

Alternative Investments. The measurement alternative has been elected for alternative investments without readily determinable fair values that do not qualify for the NAV practical expedient. The measurement alternative requires investments to be measured at cost minus impairment, if any, plus or minus adjustments resulting from observable price changes in orderly transactions for an identical or similar investment of the same issuer. Accordingly, these alternative investments are classified within Level 2 of the fair value hierarchy. At June 30, 2023, and December 31, 2022, the carrying amount of these alternative investments was $48.4 million and $42.8 million, respectively, of which $1.9 million and $5.9 million, respectively, were considered to be measured at fair value. During the three and six months ended June 30, 2023, there were $0.3 million in total write-ups due to observable price changes, and zero write-downs due to impairment.

Loans Transferred to Held for Sale. Once a decision has been made to sell loans not previously classified as held for sale, these loans are transferred into the held for sale category and carried at the lower of cost or fair value, less estimated costs to sell. At the time of transfer into held for sale classification, any amount by which cost exceeds fair value is accounted for as a valuation allowance. This activity generally pertains to loans with observable inputs, and therefore, are classified within Level 2 of the fair value hierarchy. However, should these loans include adjustments for changes in loan characteristics based on unobservable inputs, the loans would then be classified within Level 3 of the fair value hierarchy. At June 30, 2023, and December 31, 2022, there were $9.2 million and zero loans that were transferred to held for sale on the Condensed Consolidated Balance Sheet.

Collateral Dependent Loans and Leases. Loans and leases for which repayment is substantially expected to be provided through the operation or sale of collateral are considered collateral dependent, and are valued based on the estimated fair value of the collateral, less estimated costs to sell at the reporting date, using customized discounting criteria. Accordingly, collateral dependent loans and leases are classified within Level 3 of the fair value hierarchy.

Other Real Estate Owned and Repossessed Assets. OREO and repossessed assets are held at the lower of cost or fair value and are considered to be measured at fair value when recorded below cost. The fair value of OREO is calculated using independent appraisals or internal valuation methods, less estimated selling costs, and may consider available pricing guides, auction results, and price opinions. Certain repossessed assets may also require assumptions about factors that are not observable in an active market when determining fair value. Accordingly, OREO and repossessed assets are classified within Level 3 of the fair value hierarchy. At June 30, 2023, and December 31, 2022, the total book value of OREO and repossessed assets was $3.3 million and $2.3 million, respectively. In addition, the amortized cost of consumer loans secured by residential real estate property that were in process of foreclosure at June 30, 2023, was $21.5 million.

Estimated Fair Values of Financial Instruments and Mortgage Servicing Assets

The Company is required to disclose the estimated fair values of certain financial instruments and mortgage servicing rights. The following is a description of the valuation methodologies used to estimate fair value for those assets and liabilities.

Cash and Cash Equivalents. Given the short time frame to maturity, the carrying amount of cash and cash equivalents, which comprises cash and due from banks and interest-bearing deposits, approximates fair value. Cash and cash equivalents are classified within Level 1 of the fair value hierarchy.

Held-to-Maturity Securities. When quoted market prices are not available, the Company employs an independent pricing service that utilizes matrix pricing to calculate fair value. These fair value measurements consider observable data, such as dealer quotes, market spreads, cash flows, yield curves, live trading levels, trade execution data, market consensus prepayment speeds, credit information, and the respective terms and conditions for debt instruments. Management maintains procedures to monitor the pricing service's results and has a process in place to challenge their valuations and methodologies that appear unusual or unexpected. Held-to-maturity securities, which include Agency CMO, Agency MBS, Agency CMBS, Municipal bonds and notes, and CMBS, are classified within Level 2 of the fair value hierarchy.

Loans and Leases, net. Except for collateral dependent loans and leases, the fair value of loans and leases held for investment is estimated using a discounted cash flow methodology, based on future prepayments and market interest rates inclusive of an illiquidity premium for comparable loans and leases. The associated cash flows are then adjusted for associated credit risks and other potential losses, as appropriate. Loans and leases are classified within Level 3 of the fair value hierarchy.

75

Mortgage Servicing Rights. Mortgage servicing rights are initially measured at fair value and subsequently measured using the amortization method. The Company assesses mortgage servicing rights for impairment each quarter and establishes or adjusts the valuation allowance to the extent that amortized cost exceeds the estimated fair market value. Fair value is calculated as the present value of estimated future net servicing income and relies on market based assumptions for loan prepayment speeds, servicing costs, discount rates, and other economic factors. Accordingly, the primary risk inherent in valuing mortgage servicing rights is the impact of fluctuating interest rates on the related servicing revenue stream. Mortgage servicing rights are classified within Level 3 of the fair value hierarchy.

Deposit Liabilities. The fair value of deposit liabilities, which comprises demand deposits, interest-bearing checking, savings, health savings, and money market accounts, reflects the amount payable on demand at the reporting date. Deposit liabilities are classified within Level 2 of the fair value hierarchy.

Time Deposits. The fair value of fixed-maturity certificates of deposit is estimated using rates that are currently offered for deposits with similar remaining maturities. Time deposits are classified within Level 2 of the fair value hierarchy.

Securities Sold Under Agreements to Repurchase and Other Borrowings. The fair value of securities sold under agreements to repurchase and other borrowings that mature within 90 days approximates their carrying value. The fair value of securities sold under agreements to repurchase and other borrowings that mature after 90 days is estimated using a discounted cash flow methodology based on current market rates and adjusted for associated credit risks, as appropriate. Securities sold under agreements to repurchase and other borrowings are classified within Level 2 of the fair value hierarchy.

Federal Home Loan Bank Advances and Long-Term Debt. The fair value of FHLB advances and long-term debt is estimated using a discounted cash flow methodology in which discount rates are matched with the time period of the expected cash flows and adjusted for associated credit risks, as appropriate. FHLB advances and long-term debt are classified within Level 2 of the fair value hierarchy.

Note 16: Segment Reporting

The Company's operations are organized into three reportable segments that represent its primary businesses: Commercial Banking, HSA Bank, and Consumer Banking. These segments reflect how executive management responsibilities are assigned, how discrete financial information is evaluated, the type of customer served, and how products and services are provided. Certain Treasury activities, including the operations of interLINK, along with the amounts required to reconcile profitability metrics to those reported in accordance with GAAP, are included in the Corporate and Reconciling category.

In connection with the acquisition of interLINK on January 11, 2023, the $143.2 million of goodwill recorded was allocated entirely to Commercial Banking. In addition, as previously discussed in Note 2: Mergers and Acquisitions and
Note 6: Goodwill and Other Intangible Assets, the allocation of the purchase price for both the Sterling merger and Bend acquisition was final as of March 31, 2023. As a result, of the total $1.9 billion in goodwill recorded in connection with the Sterling merger, $1.7 billion and $0.2 billion was allocated to Commercial Banking and Consumer Banking, respectively. The $35.7 million of goodwill recorded in connection with the Bend acquisition was allocated entirely to HSA Bank.

Segment Reporting Methodology

The Company uses an internal profitability reporting system to generate information by reportable segment, which is based on a series of management estimates for funds transfer pricing, and allocations for non-interest expense, provision for credit losses, income taxes, and equity capital. These estimates and allocations, certain of which are subjective in nature, are periodically reviewed and refined. Changes in estimates and allocations that affect the results of any reportable segment do not affect the consolidated financial position or results of operations of the Company as a whole. The full profitability measurement reports, which are prepared for each reportable segment, reflect non-GAAP reporting methodologies. The differences between full profitability and GAAP results are reconciled in the Corporate and Reconciling category.

The Company allocates interest income and interest expense to each business through an internal matched maturity FTP process. The goal of the FTP allocation is to encourage loan and deposit growth consistent with the Company’s overall profitability objectives. The FTP process considers the specific interest rate risk and liquidity risk of financial instruments and other assets and liabilities in each line of business. Loans are assigned an FTP rate for funds used and deposits are assigned an FTP rate for funds provided. The allocation considers the origination date and the earlier of the maturity date or the repricing date of a financial instrument to assign an FTP rate for loans and deposits originated each day. The FTP process transfers the corporate interest rate risk exposure to the Treasury function included within the Corporate and Reconciling category where such exposures are centrally managed.

77

The Company allocates a majority of non-interest expense to each reportable segment using an activity and driver-based costing process. Costs, including shared services and back-office support areas, are analyzed, pooled by process, and assigned to the appropriate reportable segment. The combination of direct revenue, direct expenses, funds transfer pricing, and allocations of non-interest expense produces PPNR, which is the basis the segments are reviewed by executive management. The Company also allocates the provision for credit losses to each reportable segment based on management's estimate of the expected loss content in each of the specific loan and lease portfolios. The ACL on loans and leases is included in total assets within the Corporate and Reconciling category. Business development expenses, such as merger-related and strategic initiatives costs, are also generally included in the Corporate and Reconciling category.

The following tables present balance sheet information, including the appropriate allocations, for the Company's reportable segments and the Corporate and Reconciling category:

(1)A portion of loan and lease related fees comprises income generated from factored receivables and payroll financing activities that is within the scope of ASC Topic 606.

(2)Effective as of the fourth quarter of 2022, the wealth and investment services revenue stream was impacted by the restructuring of a process in which the Company offers brokerage, investment advisory, and certain insurance-related services to customers. The staff providing these services, who had previously been employees of the Bank, are now employees of a third-party service provider. As a result, the Company now recognizes income from this program on a net basis, which thereby reduces gross reported wealth and investment services non-interest income and the related compensation and benefits non-interest expense on the accompanying Condensed Consolidated Statements of Income.

Contracts with customers did not generate significant contract assets and liabilities at June 30, 2023, or December 31, 2022.

Major Revenue Streams

Deposit service fees consist of fees earned from commercial and consumer customer deposit accounts, such as account maintenance and cash management/analysis fees, as well as other transactional service charges (i.e., insufficient funds, wire transfers, stop payment fees, etc.). Performance obligations for account maintenance services and cash management/analysis fees are satisfied on a monthly basis at a fixed transaction price, whereas performance obligations for other deposit service charges that result from various customer-initiated transactions are satisfied at a point-in-time when the service is rendered. Payment for deposit service fees is generally received immediately or in the following month through a direct charge to the customers' accounts. Certain commercial customer contracts include credit clauses, whereby the Company will grant credit upon the customer meeting pre-determined conditions, which can be used to offset fees. On occasion, the Company may also waive certain fees. Fee waivers are recognized as a reduction to revenue in the period the waiver is granted to the customer.

The deposit service fees revenue stream also includes interchange fees earned from debit and credit card transactions. The transaction price for interchange services is based on the transaction value and the interchange rate set by the card network. Performance obligations for interchange fees are satisfied at a point-in-time when the cardholder's transaction is authorized and settled. Payment for interchange fees is generally received immediately or in the following month.

Factored receivables non-interest income consists of fees earned from accounts receivable management services. The Company factors accounts receivable, with and without recourse, for customers whereby the Company purchases their accounts receivable at a discount and assumes the risk, as applicable, and ownership of the assets through direct cash receipt from the end consumer. Factoring services are performed in exchange for a non-refundable fee at a transaction price based on a percentage of the gross invoice amount of each receivable purchased, subject to a minimum required amount. The performance obligation for factoring services is generally satisfied at a point-in-time when the receivable is assigned to the Company. However, should the commission earned not meet or exceed the minimum required annual amount, the difference between that and the actual amount is recognized at the end of the contract term. Other fees associated with factoring receivables may include wire transfer and technology fees, field examination fees, and Uniform Commercial Code fees, where the performance obligations are satisfied at a point-in-time when the services are rendered. Payment from the customer for factoring services is generally received immediately or within the following month.

Payroll finance non-interest income consists of fees earned from performing payroll financing and business process outsourcing services, including full back-office technology and tax accounting services, along with payroll preparation, making payroll tax payments, invoice billings, and collections for independently-owned temporary staffing companies nationwide. Performance obligations for payroll finance and business processing activities are either satisfied upon completion of the support services or as payroll remittances are made on behalf of customers to fund their employee payroll, which generally occurs on a weekly basis. The agreed-upon transaction price is based on a fixed-percentage per the terms of the contract, which could be subject to a hold-back reserve to provide for any balances that are assessed to be at risk of collection. When the Company collects on amounts due from end consumers on behalf of its customers and at the time of financing payroll, the Company retains the agreed-upon transaction price payable for the performance of its services and remits an amount to the customer net of any advances and payroll tax withholdings, as applicable.

Wealth and investment services consist of fees earned from asset management, trust administration, and investment advisory services, and through facilitating securities transactions. Performance obligations for asset management and trust administration services are satisfied on a monthly or quarterly basis at a transaction price based on a percentage of the period-end market value of the assets under administration. Payment for asset management and trust administration services is generally received a few days after period-end through a direct charge to the customers' accounts. Performance obligations for investment advisory services are satisfied over the period in which the services are provided through a time-based measurement of progress, and the agreed-upon transaction price with the customer varies depending on the nature of the services performed. Performance obligations for facilitating securities transactions are satisfied at a point-in-time when the securities are sold at a transaction price that is based on a percentage of the contract value. Payment for both investment advisory services and facilitating securities transactions may be received in advance of the service, but generally is received immediately or in the following period, in arrears.

Note 18: Commitments and Contingencies

Credit-Related Financial Instruments

In the normal course of business, the Company offers financial instruments with off-balance sheet risk to meet the financing needs of its customers. These transactions include commitments to extend credit, standby letters of credit, and commercial letters of credit, which involve, to varying degrees, elements of credit risk.

81

The following table summarizes the outstanding amounts of credit-related financial instruments with off-balance sheet risk:

(In thousands)	At June 30, 2023		At December 31, 2022
Commitments to extend credit	$	10,706,088	$	11,237,496
Standby letters of credit	426,658		380,655
Commercial letters of credit	54,196		53,512
Total credit-related financial instruments with off-balance sheet risk	$	11,186,942	$	11,671,663

The Company enters into contractual commitments to extend credit to its customers (i.e., revolving credit arrangements, term loan commitments, and short-term borrowing agreements), generally with fixed expiration dates or other termination clauses and that require payment of a fee. Substantially all of the Company's commitments to extend credit are contingent upon its customers maintaining specific credit standards at the time of loan funding, and are often secured by real estate collateral. Since the majority of the Company's commitments typically expire without being funded, the total contractual amount does not necessarily represent the Company's future payment requirements.

Standby letters of credit are written conditional commitments issued by the Company to guarantee its customers' performance to a third party. In the event the customer does not perform in accordance with the terms of its agreement with a third-party, the Company would be required to fund the commitment. The contractual amount of each standby letter of credit represents the maximum amount of potential future payments the Company could be required to make. Historically, the majority of the Company's standby letters of credit expire without being funded. However, if the commitment were funded, the Company has recourse against the customer. The Company's standby letter of credit agreements are often secured by cash or other collateral.

Commercial letters of credit are issued to finance either domestic or foreign customer trade arrangements. As a general rule, drafts are committed to be drawn when the goods underlying the transaction are in transit. Similar to standby letters of credit, the Company's commercial letter of credit agreements are often secured by the underlying goods subject to trade.

Allowance for Credit Losses on Unfunded Loan Commitments

An ACL is recorded under the CECL methodology and included in Accrued expenses and other liabilities on the accompanying Condensed Consolidated Balance Sheets to provide for the unused portion of commitments to lend that are not unconditionally cancellable by the Company. At June 30, 2023, and December 31, 2022, the ACL on unfunded loan commitments totaled $22.4 million and $27.7 million, respectively.Litigation

The Company is subject to certain legal proceedings and unasserted claims and assessments in the ordinary course of business. Legal contingencies are evaluated based on information currently available, including advice of counsel and assessment of available insurance coverage. The Company establishes an accrual for specific legal matters when it determines that the likelihood of an unfavorable outcome is probable and the loss is reasonably estimable. Once established, each accrual is adjusted to reflect any subsequent developments. Legal contingencies are subject to inherent uncertainties, and unfavorable rulings may occur that could cause the Company to either adjust its litigation accrual or incur actual losses that exceed the current estimate, which ultimately could have a material adverse effect, either individually or in the aggregate, on its business, financial condition, or operating results. The Company will consider settlement of cases when it is in the best interests of the Company and its stakeholders. The Company intends to defend itself in all claims asserted against it, and management currently believes that the outcome of these contingencies will not be material, either individually or in the aggregate, to the Company or its consolidated financial position.

Federal Deposit Insurance Corporation Special Assessment

On May 22, 2023, the FDIC published a proposed rule to charge certain banks a special assessment to recover losses incurred by protecting uninsured depositors of Silicon Valley Bank and Signature Bank upon their failure in March 2023. The proposed rule would levy a special assessment to certain banks at an annual rate of 12.5 basis points based on their uninsured deposits balance as of December 31, 2022, payable in eight quarterly installments beginning in the first quarter of 2024. Based on the proposed rule, the Company estimates that its total special assessment charge would be approximately $44.0 million.

The FDIC has the authority to make further changes to the proposed rule before finalization, including changes to the underlying data and calculation methodology used to determine the special assessment. The comment period on the proposed rule expired on July 21, 2023, and no final rule has been published in the Federal Register as of the date of this Quarterly Report on Form 10-Q. Accordingly, no legal obligation has been incurred, and therefore, no accrual has been recognized.

The term "disclosure controls and procedures" means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the issuer's management, including its principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.

Based on that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that as of June 30, 2023, our disclosure controls and procedures were not effective due to the un-remediated material weaknesses in internal control over financial reporting related to certain general information technology controls specific to logical access, which was previously disclosed in the Company's Annual Report on Form 10-K for the year ended December 31, 2022. Prior to the filing of this Quarterly Report on Form 10-Q (this "Form 10-Q"), we completed substantive procedures for the quarter ended June 30, 2023. Based on these procedures, management believes that our Condensed Consolidated Financial Statements included in this Form 10-Q have been prepared in accordance with GAAP. For additional information, please refer to Part II - Item 9A. of the Company's Annual Report on Form 10-K for the year ended December 31, 2022.

Remediation

Management is in process of implementing measures designed to ensure that the control deficiencies contributing to the material weaknesses are remediated, such that these controls are designed, implemented, and operating effectively. The remediation actions include: (i) designing and implementing controls related to deprovisioning, privileged access, and user access reviews, (ii) developing an enhanced risk assessment process to evaluate logical access, and (iii) improving the existing training program associated with control design and implementation. We believe that these actions will remediate the material weaknesses. The material weaknesses will not be considered remediated, however, until the applicable controls operate for a sufficient period of time and management has concluded, through testing, that these controls are operating effectively. We expect that the remediation of these material weaknesses will be completed prior to the end of 2023.

Changes in Internal Control Over Financial Reporting

Other than the ongoing remediation efforts described above, there were no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act), during the quarter ended June 30, 2023, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Limitations on Effectiveness of Controls and Procedures

Because of its inherent limitations, management does not expect that our disclosure controls and procedures or our internal control over financial reporting will prevent or detect all error and fraud. Any control system, no matter how well designed and operated, is based upon certain assumptions and can provide only reasonable, not absolute, assurance that its objectives will be met. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. Further, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud, if any, within the Company have been detected.

PART II - OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

Information regarding legal proceedings can be found within Note 18: Commitments and Contingencies in the Notes to Consolidated Financial Statements contained in Part I - Item 1. Financial Statements, which is incorporated herein by reference.

ITEM 1A. RISK FACTORS

In addition to the other information set forth in this Quarterly Report on Form 10-Q, you should carefully consider the risk factors contained in Part I - Item 1A. Risk Factors of the Company's Annual Report on Form 10-K for the year ended
December 31, 2022, which could materially affect our business, results of operations, or financial condition. For the six months ended June 30, 2023, the Company made updates to the following risk factor:

Our stock price can be volatile.

Stock price volatility may make it more difficult for stockholders to resell their common stock when they want and at prices that they find attractive. Our stock price can fluctuate significantly in response to a variety of factors including, among other things:

•actual or anticipated variations in results of operations;

•recommendations or projections by securities analysts;

•operating and stock price performance of other companies that investors deem comparable to us;

•news reports relating to trends, concerns, and other issues in the financial services and healthcare industries;

•perceptions in the marketplace regarding us and/or our competitors;

•new technology used, or services offered, by competitors;

•significant acquisitions or business combinations, strategic partnerships, joint ventures, or capital commitments by or involving us or our competitors, including those of competitor failed banks acquired by other competitors;

•changes in dividends and capital returns;

•issuance of additional shares of Webster common stock;

•changes in government regulations; and

•geopolitical conditions such as acts or threats of terrorism or military conflicts, including any military conflict between Russia and Ukraine.

General market fluctuations, including real or anticipated changes in the strength of the economy, industry factors and general economic and political conditions and events, such as economic slowdowns or recessions, interest rate changes, credit loss trends, among other factors, could also cause our stock price to decrease regardless of operating results.

Summary of Significant Accounting Policies

Summary of Significant Accounting Policies

Nature of Operations

Webster Financial Corporation is a bank holding company and financial holding company under the BHC Act, incorporated under the laws of Delaware in 1986, and headquartered in Stamford, Connecticut. Webster Bank, along with its HSA Bank division, is a leading commercial bank in the Northeast that delivers a wide range of digital and traditional financial solutions to businesses, individuals, families, and partners across its three differentiated lines of business: Commercial Banking, HSA Bank, and Consumer Banking. While its core footprint spans from New York to Rhode Island and Massachusetts, certain businesses operate in extended geographies. HSA Bank is one of the largest providers of employee benefit solutions in the United States.

Basis of Presentation

The unaudited Condensed Consolidated Financial Statements of the Company have been prepared in accordance with GAAP for interim financial information and Article 10 of Regulation S-X. Certain information and footnote disclosures required by GAAP for complete financial statements have been omitted or condensed. Therefore, the condensed consolidated financial statements should be read in conjunction with the Company's Annual Report on Form 10-K for the year ended December 31, 2022. The results of operations for the six months ended June 30, 2023, are not necessarily indicative of the future results that may be attained for the entire year or other interim periods.

In the opinion of management, all necessary adjustments have been reflected to present fairly the financial position, results of operations, and cash flows for the reporting periods presented. Intercompany transactions and balances have been eliminated in consolidation. Assets under administration or assets under management that the Company holds or manages in a fiduciary or agency capacity for customers are not included in the Condensed Consolidated Financial Statements.

Use of Estimates

The preparation of the Condensed Consolidated Financial Statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the Condensed Consolidated Financial Statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Accounting Standards Adopted in the Current Period

ASU No. 2022-02—Financial Instruments—Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures

In March 2022, the FASB issued ASU No. 2022-02, which eliminates the accounting guidance for TDRs by creditors in Subtopic 310-40, Receivables—Troubled Debt Restructurings by Creditors, while enhancing disclosure requirements for certain loan refinancings and restructurings by creditors when a borrower is experiencing financial difficulty. Specifically, rather than applying the recognition and measurement guidance for TDRs, an entity must apply the loan refinancing and restructuring guidance in paragraphs 310-20-35-9 through 35-11 to determine whether a modification results in a new loan or a continuation of an existing loan. In addition, the Update requires that an entity disclose current-period gross write-offs by year of origination for financing receivables and net investments in leases within the scope of Subtopic 326-20, Financial Instruments—Credit Losses—Measured at Amortized Cost in the vintage disclosures required by paragraph 326-20-50-6.

Modifications to borrowers experiencing financial difficulty include principal forgiveness, interest rate reductions, payment delays, term extensions, or combinations thereof. Expected losses or recoveries on loans where modifications have been granted to borrowers experiencing financial difficulty have been factored into the ACL on loans and leases. Upon adoption of ASU 2022-02, the Company is no longer required to use a discounted cash flow (or reconcilable) method to measure the ACL resulting from a modification with a borrower experiencing financial difficulty. Accordingly, the Company now applies the same credit loss methodology it uses for similar loans that were not modified.

The Company adopted the Update on January 1, 2023. The Company elected the option to apply the modified retrospective transition method related to the recognition and measurement of TDRs, which resulted in a $5.9 million increase to the Allowance for Credit Losses on Loans and Leases and a $1.7 million decrease to Deferred Tax Assets, net, with a corresponding $4.2 million cumulative-effect adjustment to retained earnings as of the adoption date. The enhanced disclosure requirements provided for by the Update were adopted on a prospective basis. Reporting periods prior to the adoption of the Update are accounted for and presented in accordance with the applicable GAAP.

Refer to Note 4: Loans and Leases for additional information regarding modifications granted to borrowers experiencing financial difficulty.

ASU No. 2022-01—Derivatives and Hedging (Topic 815): Fair Value Hedging—Portfolio Layer Method

In March 2022, the FASB issued ASU No. 2022-01—Derivatives and Hedging (Topic 815): Fair Value Hedging—Portfolio Layer Method, which expands the current last-of-layer method of hedge accounting that permits only one hedged layer to allow multiple hedged layers of a single closed portfolio. To reflect that expansion, the last-of-layer method is renamed the portfolio layer method. Additionally, the amendments in this Update: (i) expand the scope of the portfolio layer method to include non-prepayable assets; (ii) specify eligible hedging instruments in a single-layer hedge; (iii) provide additional guidance on the accounting for and disclosure of hedge basis adjustments; and (iv) specify how hedge basis adjustments should be considered when determining credit losses for the assets included in the closed portfolio. An entity may also reclassify debt securities classified in the held-to-maturity category at the date of adoption to the available-for-sale category only if the entity applies portfolio layer method hedging to one or more closed portfolios that include those debt securities within a 30-day period.

The Company adopted the Update on January 1, 2023 on a prospective basis. The adoption of this guidance did not have a material impact on the Company's Consolidated Financial Statements. The entity did not reclassify any debt securities from the held-to-maturity category to the available-for-sale category as permitted upon adoption.

ASU No. 2021-08—Business Combinations (Topic 805)—Accounting for Contract Assets and Contract Liabilities from Contracts with Customers

In October 2021, the FASB issued ASU No. 2021-08—Business Combinations (Topic 805)—Accounting for Contract Assets and Contract Liabilities from Contracts with Customers, which requires that an acquirer recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with Topic 606, Revenue from Contracts with Customers. At the acquisition date, an acquirer should account for the related revenue contracts in accordance with Topic 606 as if it had originated the contracts.

The Company adopted the Update on January 1, 2023 on a prospective basis. The adoption of this guidance did not have a material impact on the Company's Consolidated Financial Statements.

Relevant Accounting Standards Issued But Not Yet Adopted

ASU No. 2023-02—Investments—Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method (a consensus of the Emerging Issues Task Force)

In March 2023, the FASB issued ASU No. 2023-02—Investments—Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method (a consensus of the Emerging Issues Task Force), which permits reporting entities to elect to account for their tax equity investments, regardless of the program from which the income tax credits are received, using the proportional amortization method if certain conditions are met. A reporting entity may make an accounting policy election to apply the proportional amortization method in accordance with paragraph 323-740-25-4 on a tax-credit-program-by-tax-credit-program basis rather than electing to apply the proportional amortization method at the reporting entity level or to individual investments.

A reporting entity that applies the proportional amortization method to qualifying tax equity investments must account for the receipt of the investment tax credits using the flow-through method under Topic 740, Income Taxes, even if the entity applies the deferral method for other investment tax credit received. The amendments also remove certain guidance for Qualified Affordable Housing Project Investments, require the application of the delayed equity contribution guidance to all tax equity investments, and require specific disclosures that must be applied to all investments that generate income tax credits and other income tax benefits from a tax credit program for which the entity has elected to apply the proportional amortization method in accordance with Subtopic 323-740.

The Update is effective for fiscal years beginning after December 15, 2023, and interim periods within those fiscal years, with early adoption permitted. The amendments generally must be applied on either a modified retrospective or retrospective basis with a cumulative-effect adjustment to retained earnings reflecting the difference between the previous method used to account for the tax equity investment and the application of the proportional amortization method since the investment was entered into. The adoption of this guidance is not expected to have a material impact on the Consolidated Financial Statements as the Company's investments in tax credit structures are currently limited to LIHTC investments, which are already being accounted for using the proportional amortization method.

ASU No. 2023-01—Leases (Topic 842): Common Control Arrangements

In March 2023, the FASB issued ASU No. 2023-01—Leases (Topic 842): Common Control Arrangements, which requires that leasehold improvements associated with leases between entities under common control be: (i) amortized by the lessee over the useful live of the leasehold improvements to the common control group (regardless of the lease term) as long as the lessee controls the use of the underlying asset (the leased asset) through a lease; however, if the lessor obtained the right to control the use of the underlying asset through a lease with another entity not within the same common control group, the amortization period may not exceed the amortization period of the common control group; and (ii) accounted for as a transfer between entities under common control through an adjustment to equity, if, and when, the lessee no longer controls the use of the underlying asset. Additionally, those leasehold improvements are subject to the impairment guidance in Topic 360, Property, Plant, and Equipment.

The Update is effective for fiscal years beginning after December 15, 2023, and interim periods within those fiscal years, with early adoption permitted. The amendments either may be applied prospectively to all new and existing leasehold improvements recognized on or after the adoption date with any remaining unamortized balance of existing leasehold improvements amortized over their remaining useful life to the common control group determined at that date; or retrospectively to the beginning of the period in which the entity first applied Topic 842, with any leasehold improvements that otherwise would not have been amortized or impaired recognized through a cumulative-effect adjustment to the opening balance of retained earnings at the beginning of the earliest period presented in accordance with Topic 842. The Company is in the early assessment stages of evaluating the amendments and the impact of adoption on its Consolidated Financial Statements.

ASU No. 2022-03—Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions

In June 2022, the FASB issued ASU No. 2022-03—Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions, which clarifies that a contractual restriction on the sale of an equity security is not considered part of the unit of account of the equity security, and therefore, is not considered in measuring fair value. The amendments also clarify that an entity cannot, as a separate unit of account, recognize and measure a contractual sale restriction, and requires the following disclosures for equity securities subject to contractual sale restrictions: (i) the fair value of equity securities subject to contractual sale restrictions reflected on the balance sheet; (ii) the nature and remaining duration of the restriction(s); and (iii) the circumstances that could cause a lapse in the restriction(s).

The Update is effective for fiscal years beginning after December 15, 2023, and interim periods within those fiscal years, with early adoption permitted. For all entities except investment companies, the amendments should be applied prospectively with any adjustments from the adoption of the amendments recognized in earnings and disclosed on the date of adoption. The adoption of this guidance is not expected to have a material impact on the Consolidated Financial Statements and disclosures. The Company does not currently consider contractual restrictions on the sale of an equity security in measuring fair value.

Business Combination and Asset Acquisition [Abstract]

Mergers and Acquisitions

Mergers and Acquisitions

interLINK Acquisition

On January 11, 2023, Webster acquired 100% ownership of interLINK from StoneCastle Partners LLC. interLINK is a technology-enabled deposit management platform that administers over $9 billion of deposits from FDIC-insured cash sweep programs between banks and broker/dealers and clearing firms. The acquisition provides the Company with access to a unique source of core deposit funding and scalable liquidity and adds another technology-enabled channel to its already differentiated, omnichannel deposit gathering capabilities.

The total purchase price of the acquisition was $174.6 million, which included cash paid of $158.6 million and $16.0 million of contingent consideration measured at fair value. The contingent consideration is payable in cash upon the achievement of discrete customer and deposit growth events within three years of the acquisition date. Additional information regarding the determination of fair value for contingent consideration liabilities can be found within Note 14: Fair Value Measurements.

The transaction has been accounted for as a business combination, and resulted in the addition of $31.4 million in net assets measured at fair value, which primarily comprised $36.0 million of broker dealer relationship intangible assets, $6.0 million of developed technology, a $4.0 million non-competition agreement intangible asset, and $15.9 million of royalty liabilities. The $143.2 million of goodwill recognized is deductible for tax purposes. The Company's valuations of the assets acquired and liabilities assumed in the interLINK acquisition were considered final as of June 30, 2023.

Bend Financial, Inc. Acquisition

On February 18, 2022, Webster acquired 100% of the equity interests of Bend, a cloud-based platform solution provider for HSAs, in exchange for cash of $55.3 million. The transaction was accounted for as a business combination, and resulted in the addition of $19.6 million in net assets measured at fair value, which primarily comprised $15.9 million of internal use software and a $3.0 million customer relationship intangible asset. The Company's valuations of the assets acquired and liabilities assumed in the Bend acquisition were considered final as of March 31, 2023.

Merger with Sterling Bancorp

On January 31, 2022, Webster completed its merger with Sterling. The transaction was accounted for as a business combination. Accordingly, the purchase price was allocated to the assets acquired and liabilities assumed based on their fair values as of the merger effective date. The determination of fair value requires management to make estimates about discount rates, future expected cash flows, market conditions, and other future events that are highly subjective in nature and are subject to change. Fair value estimates of the assets acquired and liabilities assumed were subject to adjustment during the one-year measurement period following the closing of the merger if new information was obtained about facts and circumstances that existed as of the merger effective date that, if known, would have affected the measurement of the amounts recognized as of that date. Measurement period adjustments made during the first quarter of 2023 totaled a net $25.6 million, which pertained to other assets and other liabilities and their related deferred tax impact. The Company's valuations of the assets acquired and liabilities assumed in the merger with Sterling were considered final as of March 31, 2023.

The following table summarizes the allocation of the purchase price to the fair value of the identifiable assets acquired and liabilities assumed from Sterling as of January 31, 2022:

Total liabilities assumed			$	24,397,757
Net assets acquired			3,266,096
Goodwill			$	1,914,204

In connection with the merger with Sterling, the Company recorded $1.9 billion of goodwill, which represents the excess of the purchase price over the fair value of the net assets acquired. Information regarding the allocation of goodwill to the Company's reportable segments can be found within Note 16: Segment Reporting. For a description of the valuation methodologies used to estimate the fair values of the significant assets acquired and liabilities assumed, refer to Note 2: Mergers and Acquisitions of the Company's Annual Report on Form 10-K for the year ended December 31, 2022.

The $18.5 million increase in gross unrealized losses from December 31, 2022, to June 30, 2023, is primarily due to higher market rates. The Company assesses each available-for-sale security that is in an unrealized loss position to determine whether the decline in fair value below the amortized cost basis is a result from a credit loss or other factors. At both June 30, 2023, and December 31, 2022, no ACL was recorded on available-for-sale securities as each of the securities in the Company's portfolio are investment grade, current as to principal and interest, and their price changes are consistent with interest and credit spreads when adjusting for convexity, rating, and industry differences.

At June 30, 2023, based on current market conditions and the Company's current targeted balance sheet composition strategy, the Company intends to hold its available-for-sale securities with unrealized loss positions through the anticipated recovery period, and it is more-likely-than-not that the Company will not have to sell these available-for-sale securities before the recovery of the entire amortized cost basis. The issuers of these available-for-sale securities have not, to the Company’s knowledge, established any cause for default. Market prices are expected to approach par as the securities approach maturity.

Contractual Maturities

The following table summarizes the amortized cost and fair value of available-for-sale securities by contractual maturity:

	At June 30, 2023
(In thousands)	Amortized Cost		Fair Value
Maturing within 1 year	$	33,337	$	33,164
After 1 year through 5 years	1,040,297		978,096
After 5 through 10 years	1,401,731		1,277,563
After 10 years	6,166,939		5,470,518
Total available-for-sale securities	$	8,642,304	$	7,759,341

Available-for-sale securities that are not due at a single maturity date have been categorized based on the maturity date of the underlying collateral. Actual principal cash flows may differ from this categorization as borrowers have the right to repay their obligations with or without prepayment penalties.

Sales of Available-for Sale Securities

During the three and six months ended June 30, 2023, the Company sold U.S. Treasury notes, Corporate debt securities, and Municipal bonds and notes classified as available-for-sale for proceeds of $2.9 million and $398.3 million, respectively, which resulted in gross realized losses of $48 thousand and $20.5 million, respectively. Because $3.8 million of the total loss recognized for the six months ended June 30, 2023, was attributed to a decline in credit quality, those portions of the charges have been included in the Provision for credit losses on the accompanying Condensed Consolidated Statements of Income. There were no sales of available-for-sale securities during the three and six months ended June 30, 2022.

Other Information

The following table summarizes the carrying value of available-for-sale securities pledged for deposits, borrowings, and other purposes:

(In thousands)	At June 30, 2023		At December 31, 2022
Pledged for deposits	$	2,251,240	$	2,573,072
Pledged for borrowings and other	4,211,733		1,195,101
Total available-for-sale securities pledged	$	6,462,973	$	3,768,173

At June 30, 2023, the Company had callable available-for-sale securities with an aggregate carrying value of $2.6 billion.

Held-to-Maturity

The following tables summarize the amortized cost, fair value, and ACL on held-to-maturity securities by major type:

(1)Accrued interest receivable on held-to-maturity securities of $24.5 million and $24.2 million at June 30, 2023, and December 31, 2022, respectively, is excluded from amortized cost and is included in Accrued interest receivable and other assets on the accompanying Condensed Consolidated Balance Sheets.

An ACL on held-to-maturity securities is recorded for certain Municipal bonds and notes to account for expected lifetime credit losses. Agency securities represent obligations issued by a U.S. government-sponsored enterprise or other federally-related entity and are either explicitly or implicitly guaranteed and therefore, assumed to be zero loss. Held-to-maturity securities with gross unrealized losses and no ACL are considered to be high credit quality, and therefore, zero credit loss has been recorded.

The following table summarizes the activity in the ACL on held-to-maturity securities:

	Three months ended June 30,				Six months ended June 30,
(In thousands)	2023		2022		2023		2022

Contractual Maturities

The following table summarizes the amortized cost and fair value of held-to-maturity securities by contractual maturity:

	At June 30, 2023
(In thousands)	Amortized Cost		Fair Value
Maturing within 1 year	$	4,341	$	4,340
After 1 year through 5 years	55,954		56,141

After 10 years	6,539,039		5,679,925
Total held-to-maturity securities	$	6,944,000	$	6,066,682

Held-to-maturity securities that are not due at a single maturity date have been categorized based on the maturity date of the underlying collateral. Actual principal cash flows may differ from this categorization as borrowers have the right to prepay their obligations with or without prepayment penalties.

Credit Quality Information

The Company monitors the credit quality of held-to-maturity securities through credit ratings provided by Standard & Poor's Rating Services, Moody's Investor Services, Fitch Ratings, Inc., Kroll Bond Rating Agency, or DBRS Inc. Credit ratings express opinions about the credit quality of a security, and are updated at each quarter end. Investment grade securities are rated BBB- or higher by S&P, or Baa3 or higher by Moody's, and are generally considered by the rating agencies and market participants to be of low credit risk. Conversely, securities rated below investment grade, which are labeled as speculative grade by the rating agencies, are considered to have distinctively higher credit risk than investment grade securities. There were no speculative grade held-to-maturity securities at June 30, 2023, or December 31, 2022. Held-to-maturity securities that are not rated are collateralized with U.S. Treasury obligations.

The following tables summarize the amortized cost of held-to-maturity securities based on their lowest publicly available credit rating:

Credit Quality Indicators

To measure credit risk for the commercial portfolio, the Company employs a dual grade credit risk grading system for estimating the PD and LGD. The credit risk grade system assigns a rating to each borrower and to the facility, which together form a Composite Credit Risk Profile. The credit risk grade system categorizes borrowers by common financial characteristics that measure the credit strength of borrowers and facilities by common structural characteristics. The Composite Credit Risk Profile has ten grades, with each grade corresponding to a progressively greater risk of loss. Grades (1) to (6) are considered pass ratings, and grades (7) to (10) are considered criticized, as defined by the regulatory agencies. A (7) "Special Mention" rating has a potential weakness that, if left uncorrected, may result in deterioration of the repayment prospects for the asset. A (8) "Substandard" rating has a well-defined weakness that jeopardizes the full repayment of the debt. A (9) "Doubtful" rating has all of the same weaknesses as a substandard asset with the added characteristic that the weakness makes collection or liquidation in full given current facts, conditions, and values improbable. Assets classified as a (10) "Loss" rating are considered uncollectible and are charged-off. Risk ratings, which are assigned to differentiate risk within the portfolio, are reviewed on an ongoing basis and revised to reflect changes in a borrower's current financial position and outlook, risk profile, and the related collateral and structural position. Loan officers review updated financial information or other loan factors on at least an annual basis for all pass rated loans to assess the accuracy of the risk grade. Criticized loans undergo more frequent reviews and enhanced monitoring.

To measure credit risk for the consumer portfolio, the most relevant credit characteristic is the FICO score, which is a widely used credit scoring system that ranges from 300 to 850. A lower FICO score is indicative of higher credit risk and a higher FICO score is indicative of lower credit risk. FICO scores are updated on at least a quarterly basis.

Collateral Dependent Loans and Leases

A loan or lease is considered collateral dependent when the borrower is experiencing financial difficulty and repayment is substantially expected to be provided through the operation or sale of collateral. At June 30, 2023, and December 31, 2022, the carrying amount of collateral dependent commercial loans and leases totaled $31.9 million and $43.8 million, respectively, and the carrying amount of collateral dependent consumer loans totaled $39.2 million and $45.2 million, respectively. Commercial non-mortgage, asset-based, and equipment financing loans and leases are generally secured by machinery and equipment, inventory, receivables, or other non-real estate assets, whereas commercial real estate, multi-family, residential, home equity, and other consumer loans are secured by real estate. The ACL for collateral dependent loans and leases is individually assessed based on the fair value of the collateral less costs to sell. At June 30, 2023, and December 31, 2022, the collateral value associated with collateral dependent loans and leases totaled $91.8 million and $108.0 million, respectively.

Modifications for Borrowers Experiencing Financial Difficulty

On January 1, 2023, the Company adopted ASU 2022-02, which eliminates the accounting guidance for TDRs and enhances the disclosure requirements for certain loan modifications when a borrower is experiencing financial difficulty. For a description of the Company's accounting policies related to the accounting and reporting of TDRs, for which comparative period information is presented, refer to Note 1: Summary of Significant Accounting Policies of the Company's Annual Report on Form 10-K for the year ended December 31, 2022.

In certain circumstances, the Company enters into agreements to modify the terms of loans to borrowers experiencing financial difficulty. A variety of solutions are offered to borrowers experiencing financial difficulty, including loan modifications that may result in principal forgiveness, interest rate reductions, payment delays, term extension, or a combination thereof. The following is a description of each of these types of modifications:

•Principal forgiveness – The outstanding principal balance of a loan may be reduced by a specified amount. Principal forgiveness may occur voluntarily as part of a negotiated agreement with a borrower, or involuntarily through a bankruptcy proceeding.

•Interest rate reductions – Includes modifications where the contractual interest rate of the loan has been reduced.

•Payment delays – Deferral arrangements which allow borrowers to delay a scheduled loan payment to a later date. Deferred loan payments do not affect the original contractual terms of the loan. Modifications that result in only an insignificant payment delay are not disclosed. The Company considers that a three month or less payment delay generally would be considered insignificant.

•Term extensions – Extensions of the original contractual maturity date of the loan.

•Combination – Combination includes loans that have undergone more than one of the above loan modification types.

Significant judgment is required to determine if a borrower is experiencing financial difficulty. These considerations vary by portfolio class. The Company has identified modifications to borrowers experiencing financial difficulty that are included in its disclosures as follows:

•Commercial: The Company evaluates modifications of loans to commercial borrowers that are rated substandard or worse, and includes the modifications in its disclosures to the extent that the modification is considered
other-than-insignificant.

•Consumer: The Company evaluates modifications of loans to consumer borrowers subject to its loss mitigation program and includes them in its disclosures to the extent that the modification is considered other-than-insignificant.

The following table summarizes the amortized cost basis at June 30, 2023, of loans modified to borrowers experiencing financial difficulty, disaggregated by class and type of concession granted:

Regulatory Capital and Restrictions

Regulatory Capital and Restrictions

Capital Requirements

The Holding Company and the Bank are subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory actions by regulators that could have a direct material effect on the Company’s financial statements. Under capital adequacy guidelines and/or the regulatory framework for prompt corrective action (such provisions apply to the Bank only), both the Holding 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 regulatory directives. Capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors.

Quantitative measures established by the Basel III Capital Rules to ensure capital adequacy require the Company to maintain minimum ratios of CET1 capital to total risk-weighted assets (CET1 risk-based capital), Tier 1 capital to total risk-weighted assets (Tier 1 risk-based capital), Total capital to total risk-weighted assets (Total risk-based capital), and Tier 1 capital to average tangible assets (Tier 1 leverage capital), as defined in the regulations. CET1 capital consists of common stockholders’ equity less deductions for goodwill and other intangible assets, and certain deferred tax adjustments. Upon adoption of the Basel III Capital Rules, the Company elected to opt-out of the requirement to include certain components of AOCI in CET1 capital. Tier 1 capital consists of CET1 capital plus preferred stock. Total capital consists of Tier 1 capital and Tier 2 capital, as defined in the regulations. Tier 2 capital includes permissible portions of subordinated debt and the ACL.

At June 30, 2023, and December 31, 2022, both the Holding Company and the Bank were classified as well-capitalized. Management believes that no events or changes have occurred subsequent to year-end that would change this designation.

The following tables provides information on the capital ratios for the Holding Company and the Bank:

	At June 30, 2023
	Actual (1)				Minimum Requirement				Well Capitalized

(1)In accordance with regulatory capital rules, the Company elected an option to delay the estimated impact of the adoption of CECL on its regulatory capital over a two-year deferral period, which ended on January 1, 2022, and a subsequent three-year transition period ending on December 31, 2024. During the three-year transition period, regulatory capital ratios will phase out the aggregate amount of the regulatory capital benefit provided from the delayed CECL adoption in the initial two years. For 2022, 2023, and 2024, the Company is allowed 75%, 50%, and 25%, respectively, of the regulatory capital benefit as of December 31, 2021, with full absorption occurring in 2025.

Dividend Restrictions

The Holding Company is dependent upon dividends from the Bank to provide funds for the payment of dividends to stockholders and for other cash requirements. Dividends paid by the Bank are subject to various federal and state regulatory limitations. Express approval by the OCC is required if the effect of dividends declared would cause the regulatory capital of the Bank to fall below specified minimum levels or if the amount would exceed net income for that year combined with undistributed net income for the preceding two years. The Bank paid the Holding Company $100.0 million and $250.0 million in dividends during the three and six months ended June 30, 2023, respectively, and $125.0 million in dividends during the three and six months ended June 30, 2022, for which no express approval from the OCC was required.

Cash Restrictions

The Bank is required under Federal Reserve regulations to maintain cash reserve balances in the form of vault cash or deposits held at a FRB to ensure that it is able to meet customer demands. The reserve requirement ratio is subject to adjustment as economic conditions warrant. Effective March 26, 2020, the Federal Reserve reset the requirement to zero in order to address liquidity concerns resulting from the COVID-19 pandemic. Pursuant to this action, the Bank has not been required to hold cash reserve balances

Variable Interest Entities

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Variable Interest Entities

Variable Interest Entities

The Company has an investment interest in the following entities that each meet the definition of a variable interest entity. Information regarding the Company's consolidation of variable interest entities can be found within Note 1: Summary of Significant Accounting Policies in the Consolidated Financial Statements contained in Part II - Item 8. Financial Statements and Supplementary Data of the Company's Annual Report on Form 10-K for the year ended December 31, 2022.

Consolidated

Rabbi Trusts. The Company established a Rabbi Trust to meet its obligations due under the Webster Bank Deferred Compensation Plan for Directors and Officers and to mitigate expense volatility. The funding of the Rabbi Trust and the discontinuation of the Webster Bank Deferred Compensation Plan for Directors and Officers occurred during 2012. In connection with the Sterling merger in 2022, the Company acquired assets held in a separate Rabbi Trust that had been previously established to fund obligations due under the Greater New York Savings Bank Directors' Retirement Plan.

Investments held in the Rabbi Trusts consist primarily of mutual funds that invest in equity and fixed income securities. The Company is considered the primary beneficiary of these Rabbi Trusts as it has the power to direct the activities of the Rabbi Trusts that most significantly impact its economic performance and it has the obligation to absorb losses and/or the right to receive benefits of the Rabbi Trusts that could potentially be significant.

The Rabbi Trusts' assets are included in Accrued interest receivable and other assets on the accompanying Condensed Consolidated Balance Sheets. Investment earnings and any changes in fair value are included in Other income on the accompanying Condensed Consolidated Statements of Income. Additional information regarding the Rabbi Trusts' investments can be found within Note 14: Fair Value Measurements.

Non-Consolidated

Low-Income Housing Tax Credit Investments. The Company makes non-marketable equity investments in entities that sponsor affordable housing and other community development projects that qualify for the LIHTC Program pursuant to Section 42 of the Internal Revenue Code. The purpose of these investments is not only to assist the Bank in meeting its responsibilities under the CRA, but also to provide a return, primarily through the realization of tax benefits. While the Company's investment in an entity may exceed 50% of its outstanding equity interests, the entity is not consolidated as the Company is not the primary beneficiary. The Company has determined that it is not the primary beneficiary due to its inability to direct the activities that most significantly impact economic performance and the Company does not have the obligation to absorb losses and/or the right to receive benefits. The Company applies the proportional amortization method to subsequently measure its investments in qualified affordable housing projects.

The following table summarizes the Company's LIHTC investments and related unfunded commitments:

(In thousands)	June 30, 2023		December 31, 2022
Gross investment in LIHTC investments	$	868,459	$	797,453
Accumulated amortization	(105,719)		(69,424)
Net investment in LIHTC investments	$	762,740	$	728,029
Unfunded commitments for LIHTC investments	$	366,869	$	335,959

The aggregate carrying value of the Company's LIHTC investments is included in Accrued interest receivable and other assets on the accompanying Condensed Consolidated Balance Sheets, and represents the Company's maximum exposure to loss. The related unfunded commitments are included in Accrued expenses and other liabilities on the accompanying Condensed Consolidated Balance Sheets. There were $68.2 million and $76.7 million of net commitments approved to fund LIHTC investments during the six months ended June 30, 2023, and 2022, respectively.

Webster Statutory Trust. The Company owns all the outstanding common stock of Webster Statutory Trust, a financial vehicle that has issued, and in the future may issue, trust preferred securities. The Company is not the primary beneficiary of Webster Statutory Trust. Webster Statutory Trust's only assets are junior subordinated debentures that are issued by the Company, which were acquired using the proceeds from the issuance of trust preferred securities and common stock. The junior subordinated debentures are included in Long-term debt on the accompanying Condensed Consolidated Balance Sheets, and the related interest expense is included in Long-term debt on the accompanying Condensed Consolidated Statements of Income. Additional information regarding these junior subordinated debentures can be found within Note 8: Borrowings.

Other Non-Marketable Investments. The Company invests in alternative investments comprising interests in non-public entities that cannot be redeemed since the underlying equity is distributed as the investment is liquidated. The ultimate timing and amount of these distributions cannot be predicted with reasonable certainty. For each of these alternative investments that is classified as a variable interest entity, the Company has determined that it is not the primary beneficiary due to its inability to direct the activities that most significantly impact economic performance. The aggregate carrying value of the Company's other non-marketable investments was $170.1 million and $144.9 million at June 30, 2023, and December 31, 2022, respectively, which is included in Accrued interest receivable and other assets on the accompanying Condensed Consolidated Balance Sheets, and its maximum exposure to loss, including unfunded commitments, was $293.9 million and $243.9 million, respectively. Additional information regarding the fair value of other non-marketable investments can be found within
Note 14: Fair Value Measurements.

Earnings per common share is calculated under the two-class method in which all earnings (distributed and undistributed) are allocated to common stock and participating securities based on their respective rights to receive dividends. The Company may grant restricted stock, restricted stock units, non-qualified stock options, incentive stock options, or stock appreciation rights to certain employees and directors under its stock-based compensation programs, which entitle recipients to receive
non-forfeitable dividends during the vesting period on a basis equivalent to the dividends paid to holders of common stock. These unvested awards meet the definition of participating securities.

Potential common shares from performance-based restricted stock that were not included in the computation of dilutive earnings per common share because they were anti-dilutive under the treasury stock method were 263,674 and 174,840 for the three and six months ended June 30, 2023, respectively, and 379,308 and 298,617 for the three and six months ended
June 30, 2022, respectively.

Derivative Financial Instruments

Derivative Positions and Offsetting

Derivatives Designated as Hedging Instruments. Interest rate swaps allow the Company to change the fixed or variable nature of an interest rate without the exchange of the underlying notional amount. Certain pay fixed/receive variable interest rate swaps are designated as cash flow hedges to effectively convert variable-rate debt into fixed-rate debt, whereas certain receive fixed/pay variable interest rate swaps are designated as fair value hedges to effectively convert fixed-rate long-term debt into variable-rate debt. Certain purchased options are also designated as cash flow hedges. Purchased options allow the Company to limit the potential adverse impact of variable interest rates by establishing a cap rate or floor rate in exchange for an upfront premium. The purchased options designated as cash flow hedges represent interest rate caps where payment is received from the counterparty if interest rates rise above the cap rate, and interest rate floors where payment is received from the counterparty when interest rates fall below the floor rate.

Derivatives Not Designated as Hedging Instruments. The Company also enters into other derivative transactions to manage economic risks, but does not designate the instruments in hedge relationships. In addition, the Company enters into derivative contracts to accommodate customer needs. Derivative contracts with customers are offset with dealer counterparty transactions structured with matching terms to ensure minimal impact on earnings.

Time-value premiums, which are amortized on a straight-line basis, are excluded from the assessment of hedge effectiveness for purchased options designated as cash flow hedges. At June 30, 2023, the remaining unamortized balance of time-value premiums was $1.4 million. Over the next twelve months, an estimated decrease to interest income of $34.4 million will be reclassified from AOCI relating to cash flow hedge gain/loss, and an estimated increase to interest expense of $0.2 million will be reclassified from AOCI relating to cash flow hedge terminations. At June 30, 2023, the remaining unamortized loss on terminated cash flow hedges was $0.2 million. The maximum length of time over which forecasted transactions are hedged is 4.7 years. Additional information regarding cash flow hedge activity impacting AOCI and the related amounts reclassified to net income can be found within Note 9: Accumulated Other Comprehensive (Loss) Income, Net of Tax.

Derivative Exposure. At June 30, 2023, the Company had $4.6 million in initial margin collateral posted at clearing houses. In addition, $315.2 million of cash collateral received is included in Cash and due from banks on the accompanying Condensed Consolidated Balance Sheets. The Company regularly evaluates the credit risk of its derivative customers, taking into account the likelihood of default, net exposures, and remaining contractual life, among other related factors. Credit risk exposure is mitigated as transactions with customers are generally secured by the same collateral of the underlying transactions. Current net credit exposure relating to derivatives with the Bank's customers was $5.8 million at June 30, 2023. In addition, the Company monitors potential future exposure, representing its best estimate of exposure to remaining contractual maturity. The potential future exposure relating to derivatives with the Bank's customers totaled $101.8 million at June 30, 2023. The Company has incorporated a valuation adjustment to reflect non-performance risk in the fair value measurement of its derivatives, which totaled $6.6 million and $8.4 million at June 30, 2023, and December 31, 2022, respectively. Various factors impact changes in the valuation adjustment over time, such as changes in the credit spreads of the contracted parties, and changes in market rates and volatilities, which affect the total expected exposure of the derivative instruments.

Fair Value Disclosures [Abstract]

Fair Value Measurements

Fair Value Measurements

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The determination of fair value may require the use of estimates when quoted market prices are not available. Fair value estimates made at a specific point in time are based on management’s judgments regarding future expected losses, current economic conditions, the risk characteristics of each financial instrument, and other subjective factors that cannot be determined with precision.

The framework for measuring fair value provides a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. The three levels within the fair value hierarchy are as follows:

•Level 1: Inputs to the valuation methodology are unadjusted quoted prices for identical assets or liabilities in active markets that the Company has the ability to access at the measurement date.

•Level 2: Inputs to the valuation methodology include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in inactive markets, inputs other than quoted prices that are observable for the asset or liability (i.e., interest rates, rate volatility, prepayment speeds, and credit ratings), or inputs that are derived principally from or corroborated by market data, correlation, or other means.

•Level 3: Inputs to the valuation methodology are unobservable and significant to the fair value measurement. This includes certain pricing models or other similar techniques that require significant management judgment or estimation.

Assets and Liabilities Measured at Fair Value on a Recurring Basis

Available-for-Sale Securities. When unadjusted quoted prices are available in an active market, the Company classifies its available-for-sale investment securities within Level 1 of the fair value hierarchy. U.S. Treasury notes have a readily determinable fair value, and accordingly, are classified within Level 1 of the fair value hierarchy.

When quoted market prices are not available, the Company employs an independent pricing service that utilizes matrix pricing to calculate fair value. These fair value measurements consider observable data, such as dealer quotes, market spreads, cash flows, yield curves, live trading levels, trade execution data, market consensus prepayments speeds, credit information, and the respective terms and conditions for debt instruments. Management maintains procedures to monitor the pricing service's results and has a process in place to challenge their valuations and methodologies that appear unusual or unexpected. Government agency debentures, Municipal bonds and notes, Agency CMO, Agency MBS, Agency CMBS, CMBS, CLO, Corporate debt, Private label MBS, and Other available-for-sale securities are classified within Level 2 of the fair value hierarchy.

Derivative Instruments. The fair values presented for derivative instruments include any accrued interest. Foreign exchange contracts are valued based on unadjusted quoted prices in active markets, and accordingly, are classified within Level 1 of the fair value hierarchy. Except for mortgage banking derivatives, all other derivative instruments are valued using third-party valuation software, which considers the present value of cash flows discounted using observable forward rate assumptions. The resulting fair value is then validated against valuations performed by independent third parties. These derivative instruments are classified within Level 2 of the fair value hierarchy.

Mortgage Banking Derivatives. The Company uses forward sales of mortgage loans and mortgage-backed securities to manage the risk of loss associated with its mortgage loan commitments and mortgage loans held for sale. Prior to closing and funding certain single-family residential mortgage loans, an interest rate lock commitment is generally extended to the borrower. During this in-between time period, the Company is subject to the risk that market interest rates may change. If rates rise, investors generally will pay less to purchase mortgage loans, which would result in a reduction in the gain on sale of the loans, or possibly a loss. In an effort to mitigate this risk, forward delivery sales commitments are established in which the Company agrees to either deliver whole mortgage loans to various investors or issue mortgage-backed securities. The fair value of mortgage banking derivatives is determined based on current market prices for similar assets in the secondary market. Accordingly, mortgage banking derivatives are classified within Level 2 of the fair value hierarchy.

Originated Loans Held For Sale. The Company has elected to measure originated loans held for sale at fair value under the fair value option per ASC Topic 825, Financial Instruments. Electing to measure originated loans held for sale at fair value reduces certain timing differences and better reflects the price the Company would expect to receive from the sale of these loans. The fair value of originated loans held for sale is based on quoted market prices of similar loans sold in conjunction with securitization transactions. Accordingly, originated loans held for sale are classified within Level 2 of the fair value hierarchy.

The following table compares the fair value to the unpaid principal balance of originated loans held for sale:

	At June 30, 2023						At December 31, 2022
(In thousands)	Fair Value		Unpaid Principal Balance		Difference		Fair Value		Unpaid Principal Balance		Difference
Originated loans held for sale	$	1,800	$	1,322	$	478	$	1,991	$	1,631	$	360

Rabbi Trust Investments. Investments held in each of the Company's Rabbi Trusts consist primarily of mutual funds that invest in equity and fixed income securities. Shares of these mutual funds are valued based on the NAV as reported by the trustee of the funds, which represents quoted prices in active markets. The Company has elected to measure the Rabbi Trusts' investments at fair value. Accordingly, the Rabbi Trusts' investments are classified within Level 1 of the fair value hierarchy. At June 30, 2023, and December 31, 2022, the total cost basis of the investments held in the Rabbi Trusts was $10.2 million and $10.0 million, respectively.

Alternative Investments. Equity investments have a readily determinable fair value when unadjusted quoted prices are available in an active market for identical assets. Accordingly, these alternative investments are classified within Level 1 of the fair value hierarchy. At June 30, 2023, and December 31, 2022, equity investments with a readily determinable fair value had a total carrying amount of $0.6 million and $0.4 million, respectively, with no remaining unfunded commitment. During the three and six months ended June 30, 2023, there were total write-ups in fair value of $0.1 million and $0.2 million, respectively, associated with these alternative investments.

Equity investments that do not have a readily determinable fair value may qualify for the NAV practical expedient if they meet certain requirements. The Company's alternative investments measured at NAV consist of investments in non-public entities that cannot be redeemed since investments are distributed as the underlying equity is liquidated. Alternative investments measured at NAV are not classified within the fair value hierarchy. At June 30, 2023, and December 31, 2022, these alternative investments had a total carrying amount of $28.5 million and $89.2 million, respectively, and a remaining unfunded commitment of $27.0 million and $82.7 million, respectively.

Contingent Consideration. The Company recorded $16.0 million of contingent consideration at fair value related to two earn-out agreements associated with the acquisition of interLINK on January 11, 2023. The terms of the purchase agreement specified that the seller would receive earn-outs based on the ability of the Company to: (i) re-sign the existing broker dealers under contract, and (ii) generate $2.5 billion in new broker dealer deposit programs within three years of the acquisition date. The estimated fair values of the contingent consideration liabilities are measured on a recurring basis and determined using an income approach considering management’s evaluation of the probability of achievement, forecasted achievement date (payment term), and a discount rate equivalent to the counterparty cost of debt. These significant inputs, which are the responsibility of management and were initially calculated with the assistance of a third-party valuation specialist, are not observable and accordingly, are classified within Level 3 of the fair value hierarchy.

The following table summarizes the unobservable inputs used to derive the estimated fair value of the Company’s contingent consideration liabilities at June 30, 2023 (dollars in thousands):

Agreement	Maximum Amount		Probability of Achievement	Payment Term (in years)	Discount Rate	Fair Value
(i) Re-sign broker dealers	$	4,826	99.0 %	0.22	5.50 %	$	4,798
(ii) Deposit program growth	$	12,500	100.0 %	1.97	5.50 %	$	11,241

Contingent consideration liabilities are included within Accrued expenses and other liabilities on the accompanying Condensed Consolidated Balance Sheets. Any fair value adjustments to contingent consideration liabilities are included in Other expense on the accompanying Condensed Consolidated Statements of Income.

(2)Certain alternative investments are recorded at NAV. Assets measured at NAV are not classified within the fair value hierarchy.

Assets Measured at Fair Value on a Non-Recurring Basis

The Company measures certain assets at fair value on a non-recurring basis. The following is a description of the valuation methodologies used for assets measured at fair value on a non-recurring basis.

Alternative Investments. The measurement alternative has been elected for alternative investments without readily determinable fair values that do not qualify for the NAV practical expedient. The measurement alternative requires investments to be measured at cost minus impairment, if any, plus or minus adjustments resulting from observable price changes in orderly transactions for an identical or similar investment of the same issuer. Accordingly, these alternative investments are classified within Level 2 of the fair value hierarchy. At June 30, 2023, and December 31, 2022, the carrying amount of these alternative investments was $48.4 million and $42.8 million, respectively, of which $1.9 million and $5.9 million, respectively, were considered to be measured at fair value. During the three and six months ended June 30, 2023, there were $0.3 million in total write-ups due to observable price changes, and zero write-downs due to impairment.

Loans Transferred to Held for Sale. Once a decision has been made to sell loans not previously classified as held for sale, these loans are transferred into the held for sale category and carried at the lower of cost or fair value, less estimated costs to sell. At the time of transfer into held for sale classification, any amount by which cost exceeds fair value is accounted for as a valuation allowance. This activity generally pertains to loans with observable inputs, and therefore, are classified within Level 2 of the fair value hierarchy. However, should these loans include adjustments for changes in loan characteristics based on unobservable inputs, the loans would then be classified within Level 3 of the fair value hierarchy. At June 30, 2023, and December 31, 2022, there were $9.2 million and zero loans that were transferred to held for sale on the Condensed Consolidated Balance Sheet.

Collateral Dependent Loans and Leases. Loans and leases for which repayment is substantially expected to be provided through the operation or sale of collateral are considered collateral dependent, and are valued based on the estimated fair value of the collateral, less estimated costs to sell at the reporting date, using customized discounting criteria. Accordingly, collateral dependent loans and leases are classified within Level 3 of the fair value hierarchy.

Other Real Estate Owned and Repossessed Assets. OREO and repossessed assets are held at the lower of cost or fair value and are considered to be measured at fair value when recorded below cost. The fair value of OREO is calculated using independent appraisals or internal valuation methods, less estimated selling costs, and may consider available pricing guides, auction results, and price opinions. Certain repossessed assets may also require assumptions about factors that are not observable in an active market when determining fair value. Accordingly, OREO and repossessed assets are classified within Level 3 of the fair value hierarchy. At June 30, 2023, and December 31, 2022, the total book value of OREO and repossessed assets was $3.3 million and $2.3 million, respectively. In addition, the amortized cost of consumer loans secured by residential real estate property that were in process of foreclosure at June 30, 2023, was $21.5 million.

Estimated Fair Values of Financial Instruments and Mortgage Servicing Assets

The Company is required to disclose the estimated fair values of certain financial instruments and mortgage servicing rights. The following is a description of the valuation methodologies used to estimate fair value for those assets and liabilities.

Cash and Cash Equivalents. Given the short time frame to maturity, the carrying amount of cash and cash equivalents, which comprises cash and due from banks and interest-bearing deposits, approximates fair value. Cash and cash equivalents are classified within Level 1 of the fair value hierarchy.

Held-to-Maturity Securities. When quoted market prices are not available, the Company employs an independent pricing service that utilizes matrix pricing to calculate fair value. These fair value measurements consider observable data, such as dealer quotes, market spreads, cash flows, yield curves, live trading levels, trade execution data, market consensus prepayment speeds, credit information, and the respective terms and conditions for debt instruments. Management maintains procedures to monitor the pricing service's results and has a process in place to challenge their valuations and methodologies that appear unusual or unexpected. Held-to-maturity securities, which include Agency CMO, Agency MBS, Agency CMBS, Municipal bonds and notes, and CMBS, are classified within Level 2 of the fair value hierarchy.

Loans and Leases, net. Except for collateral dependent loans and leases, the fair value of loans and leases held for investment is estimated using a discounted cash flow methodology, based on future prepayments and market interest rates inclusive of an illiquidity premium for comparable loans and leases. The associated cash flows are then adjusted for associated credit risks and other potential losses, as appropriate. Loans and leases are classified within Level 3 of the fair value hierarchy.

Mortgage Servicing Rights. Mortgage servicing rights are initially measured at fair value and subsequently measured using the amortization method. The Company assesses mortgage servicing rights for impairment each quarter and establishes or adjusts the valuation allowance to the extent that amortized cost exceeds the estimated fair market value. Fair value is calculated as the present value of estimated future net servicing income and relies on market based assumptions for loan prepayment speeds, servicing costs, discount rates, and other economic factors. Accordingly, the primary risk inherent in valuing mortgage servicing rights is the impact of fluctuating interest rates on the related servicing revenue stream. Mortgage servicing rights are classified within Level 3 of the fair value hierarchy.

Deposit Liabilities. The fair value of deposit liabilities, which comprises demand deposits, interest-bearing checking, savings, health savings, and money market accounts, reflects the amount payable on demand at the reporting date. Deposit liabilities are classified within Level 2 of the fair value hierarchy.

Time Deposits. The fair value of fixed-maturity certificates of deposit is estimated using rates that are currently offered for deposits with similar remaining maturities. Time deposits are classified within Level 2 of the fair value hierarchy.

Securities Sold Under Agreements to Repurchase and Other Borrowings. The fair value of securities sold under agreements to repurchase and other borrowings that mature within 90 days approximates their carrying value. The fair value of securities sold under agreements to repurchase and other borrowings that mature after 90 days is estimated using a discounted cash flow methodology based on current market rates and adjusted for associated credit risks, as appropriate. Securities sold under agreements to repurchase and other borrowings are classified within Level 2 of the fair value hierarchy.

Federal Home Loan Bank Advances and Long-Term Debt. The fair value of FHLB advances and long-term debt is estimated using a discounted cash flow methodology in which discount rates are matched with the time period of the expected cash flows and adjusted for associated credit risks, as appropriate. FHLB advances and long-term debt are classified within Level 2 of the fair value hierarchy.

The following table summarizes the carrying amounts, estimated fair values, and classifications within the fair value hierarchy of selected financial instruments and mortgage servicing rights:

Segment Reporting [Abstract]

Segment Reporting

Segment Reporting

The Company's operations are organized into three reportable segments that represent its primary businesses: Commercial Banking, HSA Bank, and Consumer Banking. These segments reflect how executive management responsibilities are assigned, how discrete financial information is evaluated, the type of customer served, and how products and services are provided. Certain Treasury activities, including the operations of interLINK, along with the amounts required to reconcile profitability metrics to those reported in accordance with GAAP, are included in the Corporate and Reconciling category.

In connection with the acquisition of interLINK on January 11, 2023, the $143.2 million of goodwill recorded was allocated entirely to Commercial Banking. In addition, as previously discussed in Note 2: Mergers and Acquisitions and
Note 6: Goodwill and Other Intangible Assets, the allocation of the purchase price for both the Sterling merger and Bend acquisition was final as of March 31, 2023. As a result, of the total $1.9 billion in goodwill recorded in connection with the Sterling merger, $1.7 billion and $0.2 billion was allocated to Commercial Banking and Consumer Banking, respectively. The $35.7 million of goodwill recorded in connection with the Bend acquisition was allocated entirely to HSA Bank.

Segment Reporting Methodology

The Company uses an internal profitability reporting system to generate information by reportable segment, which is based on a series of management estimates for funds transfer pricing, and allocations for non-interest expense, provision for credit losses, income taxes, and equity capital. These estimates and allocations, certain of which are subjective in nature, are periodically reviewed and refined. Changes in estimates and allocations that affect the results of any reportable segment do not affect the consolidated financial position or results of operations of the Company as a whole. The full profitability measurement reports, which are prepared for each reportable segment, reflect non-GAAP reporting methodologies. The differences between full profitability and GAAP results are reconciled in the Corporate and Reconciling category.

The Company allocates interest income and interest expense to each business through an internal matched maturity FTP process. The goal of the FTP allocation is to encourage loan and deposit growth consistent with the Company’s overall profitability objectives. The FTP process considers the specific interest rate risk and liquidity risk of financial instruments and other assets and liabilities in each line of business. Loans are assigned an FTP rate for funds used and deposits are assigned an FTP rate for funds provided. The allocation considers the origination date and the earlier of the maturity date or the repricing date of a financial instrument to assign an FTP rate for loans and deposits originated each day. The FTP process transfers the corporate interest rate risk exposure to the Treasury function included within the Corporate and Reconciling category where such exposures are centrally managed.

The Company allocates a majority of non-interest expense to each reportable segment using an activity and driver-based costing process. Costs, including shared services and back-office support areas, are analyzed, pooled by process, and assigned to the appropriate reportable segment. The combination of direct revenue, direct expenses, funds transfer pricing, and allocations of non-interest expense produces PPNR, which is the basis the segments are reviewed by executive management. The Company also allocates the provision for credit losses to each reportable segment based on management's estimate of the expected loss content in each of the specific loan and lease portfolios. The ACL on loans and leases is included in total assets within the Corporate and Reconciling category. Business development expenses, such as merger-related and strategic initiatives costs, are also generally included in the Corporate and Reconciling category.

(1)A portion of loan and lease related fees comprises income generated from factored receivables and payroll financing activities that is within the scope of ASC Topic 606.

(2)Effective as of the fourth quarter of 2022, the wealth and investment services revenue stream was impacted by the restructuring of a process in which the Company offers brokerage, investment advisory, and certain insurance-related services to customers. The staff providing these services, who had previously been employees of the Bank, are now employees of a third-party service provider. As a result, the Company now recognizes income from this program on a net basis, which thereby reduces gross reported wealth and investment services non-interest income and the related compensation and benefits non-interest expense on the accompanying Condensed Consolidated Statements of Income.

Contracts with customers did not generate significant contract assets and liabilities at June 30, 2023, or December 31, 2022.

Major Revenue Streams

Deposit service fees consist of fees earned from commercial and consumer customer deposit accounts, such as account maintenance and cash management/analysis fees, as well as other transactional service charges (i.e., insufficient funds, wire transfers, stop payment fees, etc.). Performance obligations for account maintenance services and cash management/analysis fees are satisfied on a monthly basis at a fixed transaction price, whereas performance obligations for other deposit service charges that result from various customer-initiated transactions are satisfied at a point-in-time when the service is rendered. Payment for deposit service fees is generally received immediately or in the following month through a direct charge to the customers' accounts. Certain commercial customer contracts include credit clauses, whereby the Company will grant credit upon the customer meeting pre-determined conditions, which can be used to offset fees. On occasion, the Company may also waive certain fees. Fee waivers are recognized as a reduction to revenue in the period the waiver is granted to the customer.

The deposit service fees revenue stream also includes interchange fees earned from debit and credit card transactions. The transaction price for interchange services is based on the transaction value and the interchange rate set by the card network. Performance obligations for interchange fees are satisfied at a point-in-time when the cardholder's transaction is authorized and settled. Payment for interchange fees is generally received immediately or in the following month.

Factored receivables non-interest income consists of fees earned from accounts receivable management services. The Company factors accounts receivable, with and without recourse, for customers whereby the Company purchases their accounts receivable at a discount and assumes the risk, as applicable, and ownership of the assets through direct cash receipt from the end consumer. Factoring services are performed in exchange for a non-refundable fee at a transaction price based on a percentage of the gross invoice amount of each receivable purchased, subject to a minimum required amount. The performance obligation for factoring services is generally satisfied at a point-in-time when the receivable is assigned to the Company. However, should the commission earned not meet or exceed the minimum required annual amount, the difference between that and the actual amount is recognized at the end of the contract term. Other fees associated with factoring receivables may include wire transfer and technology fees, field examination fees, and Uniform Commercial Code fees, where the performance obligations are satisfied at a point-in-time when the services are rendered. Payment from the customer for factoring services is generally received immediately or within the following month.

Payroll finance non-interest income consists of fees earned from performing payroll financing and business process outsourcing services, including full back-office technology and tax accounting services, along with payroll preparation, making payroll tax payments, invoice billings, and collections for independently-owned temporary staffing companies nationwide. Performance obligations for payroll finance and business processing activities are either satisfied upon completion of the support services or as payroll remittances are made on behalf of customers to fund their employee payroll, which generally occurs on a weekly basis. The agreed-upon transaction price is based on a fixed-percentage per the terms of the contract, which could be subject to a hold-back reserve to provide for any balances that are assessed to be at risk of collection. When the Company collects on amounts due from end consumers on behalf of its customers and at the time of financing payroll, the Company retains the agreed-upon transaction price payable for the performance of its services and remits an amount to the customer net of any advances and payroll tax withholdings, as applicable.

Wealth and investment services consist of fees earned from asset management, trust administration, and investment advisory services, and through facilitating securities transactions. Performance obligations for asset management and trust administration services are satisfied on a monthly or quarterly basis at a transaction price based on a percentage of the period-end market value of the assets under administration. Payment for asset management and trust administration services is generally received a few days after period-end through a direct charge to the customers' accounts. Performance obligations for investment advisory services are satisfied over the period in which the services are provided through a time-based measurement of progress, and the agreed-upon transaction price with the customer varies depending on the nature of the services performed. Performance obligations for facilitating securities transactions are satisfied at a point-in-time when the securities are sold at a transaction price that is based on a percentage of the contract value. Payment for both investment advisory services and facilitating securities transactions may be received in advance of the service, but generally is received immediately or in the following period, in arrears.

Commitments and Contingencies

Commitments and Contingencies

Credit-Related Financial Instruments

In the normal course of business, the Company offers financial instruments with off-balance sheet risk to meet the financing needs of its customers. These transactions include commitments to extend credit, standby letters of credit, and commercial letters of credit, which involve, to varying degrees, elements of credit risk.

The following table summarizes the outstanding amounts of credit-related financial instruments with off-balance sheet risk:

(In thousands)	At June 30, 2023		At December 31, 2022
Commitments to extend credit	$	10,706,088	$	11,237,496
Standby letters of credit	426,658		380,655
Commercial letters of credit	54,196		53,512
Total credit-related financial instruments with off-balance sheet risk	$	11,186,942	$	11,671,663

The Company enters into contractual commitments to extend credit to its customers (i.e., revolving credit arrangements, term loan commitments, and short-term borrowing agreements), generally with fixed expiration dates or other termination clauses and that require payment of a fee. Substantially all of the Company's commitments to extend credit are contingent upon its customers maintaining specific credit standards at the time of loan funding, and are often secured by real estate collateral. Since the majority of the Company's commitments typically expire without being funded, the total contractual amount does not necessarily represent the Company's future payment requirements.

Standby letters of credit are written conditional commitments issued by the Company to guarantee its customers' performance to a third party. In the event the customer does not perform in accordance with the terms of its agreement with a third-party, the Company would be required to fund the commitment. The contractual amount of each standby letter of credit represents the maximum amount of potential future payments the Company could be required to make. Historically, the majority of the Company's standby letters of credit expire without being funded. However, if the commitment were funded, the Company has recourse against the customer. The Company's standby letter of credit agreements are often secured by cash or other collateral.

Commercial letters of credit are issued to finance either domestic or foreign customer trade arrangements. As a general rule, drafts are committed to be drawn when the goods underlying the transaction are in transit. Similar to standby letters of credit, the Company's commercial letter of credit agreements are often secured by the underlying goods subject to trade.

Allowance for Credit Losses on Unfunded Loan Commitments

An ACL is recorded under the CECL methodology and included in Accrued expenses and other liabilities on the accompanying Condensed Consolidated Balance Sheets to provide for the unused portion of commitments to lend that are not unconditionally cancellable by the Company. At June 30, 2023, and December 31, 2022, the ACL on unfunded loan commitments totaled $22.4 million and $27.7 million, respectively.Litigation

The Company is subject to certain legal proceedings and unasserted claims and assessments in the ordinary course of business. Legal contingencies are evaluated based on information currently available, including advice of counsel and assessment of available insurance coverage. The Company establishes an accrual for specific legal matters when it determines that the likelihood of an unfavorable outcome is probable and the loss is reasonably estimable. Once established, each accrual is adjusted to reflect any subsequent developments. Legal contingencies are subject to inherent uncertainties, and unfavorable rulings may occur that could cause the Company to either adjust its litigation accrual or incur actual losses that exceed the current estimate, which ultimately could have a material adverse effect, either individually or in the aggregate, on its business, financial condition, or operating results. The Company will consider settlement of cases when it is in the best interests of the Company and its stakeholders. The Company intends to defend itself in all claims asserted against it, and management currently believes that the outcome of these contingencies will not be material, either individually or in the aggregate, to the Company or its consolidated financial position.

Federal Deposit Insurance Corporation Special Assessment

On May 22, 2023, the FDIC published a proposed rule to charge certain banks a special assessment to recover losses incurred by protecting uninsured depositors of Silicon Valley Bank and Signature Bank upon their failure in March 2023. The proposed rule would levy a special assessment to certain banks at an annual rate of 12.5 basis points based on their uninsured deposits balance as of December 31, 2022, payable in eight quarterly installments beginning in the first quarter of 2024. Based on the proposed rule, the Company estimates that its total special assessment charge would be approximately $44.0 million.

The FDIC has the authority to make further changes to the proposed rule before finalization, including changes to the underlying data and calculation methodology used to determine the special assessment. The comment period on the proposed rule expired on July 21, 2023, and no final rule has been published in the Federal Register as of the date of this Quarterly Report on Form 10-Q.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation

Basis of Presentation

The unaudited Condensed Consolidated Financial Statements of the Company have been prepared in accordance with GAAP for interim financial information and Article 10 of Regulation S-X. Certain information and footnote disclosures required by GAAP for complete financial statements have been omitted or condensed. Therefore, the condensed consolidated financial statements should be read in conjunction with the Company's Annual Report on Form 10-K for the year ended December 31, 2022. The results of operations for the six months ended June 30, 2023, are not necessarily indicative of the future results that may be attained for the entire year or other interim periods.

In the opinion of management, all necessary adjustments have been reflected to present fairly the financial position, results of operations, and cash flows for the reporting periods presented. Intercompany transactions and balances have been eliminated in consolidation. Assets under administration or assets under management that the Company holds or manages in a fiduciary or agency capacity for customers are not included in the Condensed Consolidated Financial Statements.

Use of Estimates

Use of Estimates

The preparation of the Condensed Consolidated Financial Statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the Condensed Consolidated Financial Statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Relevant Accounting Standards Issued But Not Yet Adopted

Accounting Standards Adopted in the Current Period

ASU No. 2022-02—Financial Instruments—Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures

In March 2022, the FASB issued ASU No. 2022-02, which eliminates the accounting guidance for TDRs by creditors in Subtopic 310-40, Receivables—Troubled Debt Restructurings by Creditors, while enhancing disclosure requirements for certain loan refinancings and restructurings by creditors when a borrower is experiencing financial difficulty. Specifically, rather than applying the recognition and measurement guidance for TDRs, an entity must apply the loan refinancing and restructuring guidance in paragraphs 310-20-35-9 through 35-11 to determine whether a modification results in a new loan or a continuation of an existing loan. In addition, the Update requires that an entity disclose current-period gross write-offs by year of origination for financing receivables and net investments in leases within the scope of Subtopic 326-20, Financial Instruments—Credit Losses—Measured at Amortized Cost in the vintage disclosures required by paragraph 326-20-50-6.

Modifications to borrowers experiencing financial difficulty include principal forgiveness, interest rate reductions, payment delays, term extensions, or combinations thereof. Expected losses or recoveries on loans where modifications have been granted to borrowers experiencing financial difficulty have been factored into the ACL on loans and leases. Upon adoption of ASU 2022-02, the Company is no longer required to use a discounted cash flow (or reconcilable) method to measure the ACL resulting from a modification with a borrower experiencing financial difficulty. Accordingly, the Company now applies the same credit loss methodology it uses for similar loans that were not modified.

The Company adopted the Update on January 1, 2023. The Company elected the option to apply the modified retrospective transition method related to the recognition and measurement of TDRs, which resulted in a $5.9 million increase to the Allowance for Credit Losses on Loans and Leases and a $1.7 million decrease to Deferred Tax Assets, net, with a corresponding $4.2 million cumulative-effect adjustment to retained earnings as of the adoption date. The enhanced disclosure requirements provided for by the Update were adopted on a prospective basis. Reporting periods prior to the adoption of the Update are accounted for and presented in accordance with the applicable GAAP.

Refer to Note 4: Loans and Leases for additional information regarding modifications granted to borrowers experiencing financial difficulty.

ASU No. 2022-01—Derivatives and Hedging (Topic 815): Fair Value Hedging—Portfolio Layer Method

In March 2022, the FASB issued ASU No. 2022-01—Derivatives and Hedging (Topic 815): Fair Value Hedging—Portfolio Layer Method, which expands the current last-of-layer method of hedge accounting that permits only one hedged layer to allow multiple hedged layers of a single closed portfolio. To reflect that expansion, the last-of-layer method is renamed the portfolio layer method. Additionally, the amendments in this Update: (i) expand the scope of the portfolio layer method to include non-prepayable assets; (ii) specify eligible hedging instruments in a single-layer hedge; (iii) provide additional guidance on the accounting for and disclosure of hedge basis adjustments; and (iv) specify how hedge basis adjustments should be considered when determining credit losses for the assets included in the closed portfolio. An entity may also reclassify debt securities classified in the held-to-maturity category at the date of adoption to the available-for-sale category only if the entity applies portfolio layer method hedging to one or more closed portfolios that include those debt securities within a 30-day period.

The Company adopted the Update on January 1, 2023 on a prospective basis. The adoption of this guidance did not have a material impact on the Company's Consolidated Financial Statements. The entity did not reclassify any debt securities from the held-to-maturity category to the available-for-sale category as permitted upon adoption.

ASU No. 2021-08—Business Combinations (Topic 805)—Accounting for Contract Assets and Contract Liabilities from Contracts with Customers

In October 2021, the FASB issued ASU No. 2021-08—Business Combinations (Topic 805)—Accounting for Contract Assets and Contract Liabilities from Contracts with Customers, which requires that an acquirer recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with Topic 606, Revenue from Contracts with Customers. At the acquisition date, an acquirer should account for the related revenue contracts in accordance with Topic 606 as if it had originated the contracts.

The Company adopted the Update on January 1, 2023 on a prospective basis. The adoption of this guidance did not have a material impact on the Company's Consolidated Financial Statements.

Relevant Accounting Standards Issued But Not Yet Adopted

ASU No. 2023-02—Investments—Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method (a consensus of the Emerging Issues Task Force)

In March 2023, the FASB issued ASU No. 2023-02—Investments—Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method (a consensus of the Emerging Issues Task Force), which permits reporting entities to elect to account for their tax equity investments, regardless of the program from which the income tax credits are received, using the proportional amortization method if certain conditions are met. A reporting entity may make an accounting policy election to apply the proportional amortization method in accordance with paragraph 323-740-25-4 on a tax-credit-program-by-tax-credit-program basis rather than electing to apply the proportional amortization method at the reporting entity level or to individual investments.

A reporting entity that applies the proportional amortization method to qualifying tax equity investments must account for the receipt of the investment tax credits using the flow-through method under Topic 740, Income Taxes, even if the entity applies the deferral method for other investment tax credit received. The amendments also remove certain guidance for Qualified Affordable Housing Project Investments, require the application of the delayed equity contribution guidance to all tax equity investments, and require specific disclosures that must be applied to all investments that generate income tax credits and other income tax benefits from a tax credit program for which the entity has elected to apply the proportional amortization method in accordance with Subtopic 323-740.

The Update is effective for fiscal years beginning after December 15, 2023, and interim periods within those fiscal years, with early adoption permitted. The amendments generally must be applied on either a modified retrospective or retrospective basis with a cumulative-effect adjustment to retained earnings reflecting the difference between the previous method used to account for the tax equity investment and the application of the proportional amortization method since the investment was entered into. The adoption of this guidance is not expected to have a material impact on the Consolidated Financial Statements as the Company's investments in tax credit structures are currently limited to LIHTC investments, which are already being accounted for using the proportional amortization method.

ASU No. 2023-01—Leases (Topic 842): Common Control Arrangements

In March 2023, the FASB issued ASU No. 2023-01—Leases (Topic 842): Common Control Arrangements, which requires that leasehold improvements associated with leases between entities under common control be: (i) amortized by the lessee over the useful live of the leasehold improvements to the common control group (regardless of the lease term) as long as the lessee controls the use of the underlying asset (the leased asset) through a lease; however, if the lessor obtained the right to control the use of the underlying asset through a lease with another entity not within the same common control group, the amortization period may not exceed the amortization period of the common control group; and (ii) accounted for as a transfer between entities under common control through an adjustment to equity, if, and when, the lessee no longer controls the use of the underlying asset. Additionally, those leasehold improvements are subject to the impairment guidance in Topic 360, Property, Plant, and Equipment.

The Update is effective for fiscal years beginning after December 15, 2023, and interim periods within those fiscal years, with early adoption permitted. The amendments either may be applied prospectively to all new and existing leasehold improvements recognized on or after the adoption date with any remaining unamortized balance of existing leasehold improvements amortized over their remaining useful life to the common control group determined at that date; or retrospectively to the beginning of the period in which the entity first applied Topic 842, with any leasehold improvements that otherwise would not have been amortized or impaired recognized through a cumulative-effect adjustment to the opening balance of retained earnings at the beginning of the earliest period presented in accordance with Topic 842. The Company is in the early assessment stages of evaluating the amendments and the impact of adoption on its Consolidated Financial Statements.

ASU No. 2022-03—Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions

In June 2022, the FASB issued ASU No. 2022-03—Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions, which clarifies that a contractual restriction on the sale of an equity security is not considered part of the unit of account of the equity security, and therefore, is not considered in measuring fair value. The amendments also clarify that an entity cannot, as a separate unit of account, recognize and measure a contractual sale restriction, and requires the following disclosures for equity securities subject to contractual sale restrictions: (i) the fair value of equity securities subject to contractual sale restrictions reflected on the balance sheet; (ii) the nature and remaining duration of the restriction(s); and (iii) the circumstances that could cause a lapse in the restriction(s).

The Update is effective for fiscal years beginning after December 15, 2023, and interim periods within those fiscal years, with early adoption permitted. For all entities except investment companies, the amendments should be applied prospectively with any adjustments from the adoption of the amendments recognized in earnings and disclosed on the date of adoption. The adoption of this guidance is not expected to have a material impact on the Consolidated Financial Statements and disclosures. The Company does not currently consider contractual restrictions on the sale of an equity security in measuring fair value.

(1)A portion of loan and lease related fees comprises income generated from factored receivables and payroll financing activities that is within the scope of ASC Topic 606.

(2)Effective as of the fourth quarter of 2022, the wealth and investment services revenue stream was impacted by the restructuring of a process in which the Company offers brokerage, investment advisory, and certain insurance-related services to customers. The staff providing these services, who had previously been employees of the Bank, are now employees of a third-party service provider. As a result, the Company now recognizes income from this program on a net basis, which thereby reduces gross reported wealth and investment services non-interest income and the related compensation and benefits non-interest expense on the accompanying Condensed Consolidated Statements of Income.
