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 Waterbury, Connecticut. Webster Bank is the principal consolidated subsidiary of Webster Financial Corporation. Webster Bank and its HSA Bank division deliver a wide range of banking, investment, and financial services to individuals, families, and businesses.

Webster Bank serves consumer and business customers with mortgage lending, financial planning, trust, and investment services through a distribution network consisting of banking centers, ATMs, a customer care center, and a full range of web and mobile-based banking services throughout southern New England and Westchester County, New York. It also offers equipment financing, commercial real estate lending, asset-based lending, and treasury and payment solutions primarily in the eastern U.S. HSA Bank is a leading provider of health savings accounts, while also delivering health reimbursement arrangements, and flexible spending and commuter benefit account administration services to employers and individuals in all 50 states.

The accounting and reporting policies of the Company that materially affect its financial statements conform with GAAP, and align with general practices within the financial services industry. The Consolidated Financial Statements and the accompanying Notes thereto include the accounts of Webster Financial Corporation and all other entities in which it has a controlling financial interest. Intercompany accounts and transactions have been eliminated in consolidation.

The purpose of consolidated financial statements is to present the results of operations and the financial position of the Company and its subsidiaries as if the consolidated group were a single economic entity. In accordance with the applicable accounting guidance for consolidations, the consolidated financial statements include any voting interest entity (VOE) in which the Company has a controlling financial interest and any variable interest entity (VIE) for which the Company is deemed to be the primary beneficiary. The Company generally consolidates its VOEs if the Company, directly or indirectly, owns more than 50% of the outstanding voting shares of the entity and the non-controlling shareholders do not hold any substantive participating or controlling rights.

The Company evaluates VIEs to understand the purpose and design of the entity, and its involvement in the ongoing activities of the VIE and will consolidate the VIE if it has (i) the power to direct the activities of the VIE that most significantly affect the VIE's economic performance and (ii) an obligation to absorb losses of the VIE, or the right to receive benefits from the VIE, that could potentially be significant to the VIE.

The Company accounts for unconsolidated partnerships and certain other investments using the equity method of accounting if it has the ability to significantly influence the operating and financial policies of the investee. This is generally presumed to exist when the Company owns between 20% and 50% of a corporation, or when it has greater than 3%-5% interest in a limited partnership or similarly structured entity. Refer to Note 2: Variable Interest Entities for further information.

Interest-bearing deposits, as referenced in the consolidated balance sheets, includes deposits at the FRB of Boston in excess of reserve requirements and federal funds sold to other financial institutions. Federal funds sold essentially represents an uncollateralized loan and therefore the Company regularly evaluates the credit risk associated with the other financial institutions to assure that Webster does not become exposed to any significant credit risk on those cash equivalents.

Investment securities are classified as available-for-sale or held-to-maturity at the time of purchase. Any classification change subsequent to trade date is reviewed for compliance with corporate objectives and accounting policies. Debt securities classified as held-to-maturity are those which Webster has the ability and intent to hold to maturity. Securities classified as held-to-maturity are recorded at amortized cost net of unamortized premiums and discounts. Discount accretion income and premium amortization expense are recognized as interest income using the effective interest method, with consideration given to prepayment assumptions on mortgage backed securities. Premiums are amortized to the earliest call date for debt securities purchased at a premium, with explicit, non-contingent call features and are callable at a fixed price and preset date. Securities classified as available-for-sale are recorded at fair value with unrealized gains and losses recorded as a component of other comprehensive income (OCI) or other comprehensive loss (OCL). If securities are transferred from available-for-sale to held-to-maturity they are recorded at fair value at the time of transfer and the respective gain or loss would be recorded as a separate component of OCI or OCL and amortized as an adjustment to interest income over the remaining life of such security.

Securities classified as available-for-sale or held-to-maturity and in an unrealized loss position are evaluated for other-than-temporary impairment (OTTI) on a quarterly basis. The evaluation considers several qualitative factors, including the period of time the security has been in a loss position, and the amount of the unrealized loss. If the Company intends to sell a debt security or it is more likely than not the Company will be required to sell the debt security prior to recovery of its amortized cost basis, it is written down to fair value, and the loss is recognized in non-interest income. If the Company does not intend to sell the debt security and it is more likely than not that the Company will not be required to sell the debt security prior to recovery of its amortized cost basis, only the credit component of the unrealized loss is recorded as an impairment charge in non-interest income. The remaining loss component would be recorded to accumulated other comprehensive loss, net of tax (AOCL).

Debt security transactions are recognized on the trade date, which is the date the order to buy or sell the security is executed. The carrying value plus any related accumulated OCI or OCL balance of sold securities is used to calculate the realized gain or loss on sale. The specific identification method is used to determine realized gains and losses on sales of securities. Refer to Note 3: Investment Securities for further information.

The Company’s accounting treatment for equity investments differs for those with and without readily determinable fair values. Equity investments with readily determinable fair values are recorded at fair value with changes in fair value recorded in non-interest income. For equity investments without readily determinable fair values, the Company elected the measurement alternative, and therefore carry these investments at cost, less impairment, if any, plus or minus changes in observable prices. Certain equity investments that do not have a readily available fair value may qualify for net asset value (NAV) measurement based on specific requirements. The Company's alternative investments accounted for at NAV consist of investments in non-public entities that generally cannot be redeemed since the Company’s investments are distributed as the underlying equity is liquidated. On a quarterly basis, the Company reviews its equity investments without readily determinable fair values for impairment. If the equity investment is considered impaired, an impairment loss equal to the amount by which the carrying value exceeds its fair value is recorded through a charge to earnings. The impairment loss may be reversed in a subsequent period if there are observable transactions for the identical or similar investment of the same issuer at a higher amount than the carrying amount that was established when the impairment was recognized. Impairment as well as upward or downward adjustments resulting from observable price changes in orderly transactions for identical or similar investments are included in non-interest income.

Loans that are classified as held for sale at the time of origination are accounted for under the fair value option. Loans not originated for sale but subsequently transferred to held for sale are valued at the lower of cost or fair value and are valued on an individual asset basis. Any cost amount in excess of fair value is recorded as a valuation allowance and recognized as a reduction of other non-interest income.

Gains or losses on the sale of loans held for sale are recorded as part of mortgage banking activities. Cash flows from the sale of loans that were originated specifically for resale are presented as operating cash flows. Cash flows from the sale of loans originated for investment then subsequently transferred to held for sale are presented as investing cash flows. Refer to Note 5: Transfers of Financial Assets for further information.

Transfers of financial assets are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is generally considered to have been surrendered when: (i) the transferred assets are legally isolated from the Company or its consolidated affiliates, even in bankruptcy or other receivership; (ii) the transferee has the right to pledge or exchange the assets with no conditions that constrain the transferee and provide more than a trivial benefit to the Company; and (iii) the Company does not maintain the obligation or unilateral ability to reclaim or repurchase the assets.

The Company sells financial assets in the normal course of business, the majority of which are residential mortgage loan sales, primarily to government-sponsored enterprises through established programs, commercial loan sales through participation agreements, and other individual or portfolio loan and securities sales. In accordance with accounting guidance for asset transfers, the Company considers any ongoing involvement with transferred assets in determining whether the assets can be derecognized from the balance sheet. With the exception of servicing and certain performance-based guarantees, the Company’s continuing involvement with financial assets sold is minimal and generally limited to market customary representation and warranty clauses covering certain characteristics of the mortgage loans sold and the Company's origination process. The gain or loss on sale depends on the previous carrying amount of the transferred financial assets, the consideration received, and any other assets obtained or liabilities incurred in exchange for the transferred assets.

Loans and leases are stated at the principal amount outstanding, net of amounts charged off, unearned income, unamortized premiums and discounts, and deferred loan and lease fees or costs which are recognized as yield adjustments using the effective interest method. These yield adjustments are amortized over the contractual life of the related loans and leases adjusted for prepayments when applicable. Interest on loans and leases is credited to interest income as earned based on the interest rate applied to principal amounts outstanding. Prepayment fees are recognized in non-interest income. Cash flows from loans and leases are presented as investing cash flows.

Loans and leases are placed on non-accrual status when collection of principal and interest in accordance with contractual terms is doubtful, generally when principal or interest payments become 90 days delinquent, unless the loan or lease is well secured and in process of collection, or sooner if management concludes circumstances indicate that the borrower may be unable to meet contractual principal or interest payments. Residential real estate loans, excluding loans fully insured against loss and in the process of collection, and consumer loans are placed on non-accrual status at 90 days past due, or at the date when the Company is notified that the borrower is discharged in bankruptcy. Residential loans that are more than 90 days past due, fully insured against loss, and in the process of collection, remain accruing and are reported as 90 days or more past due and accruing. Commercial, commercial real estate loans, and equipment finance loans or leases are subject to a detailed review when 90 days past due to determine accrual status, or when payment is uncertain and a specific consideration is made to put a loan or lease on non-accrual status.

When loans and leases are placed on non-accrual status, the accrual of interest is discontinued, and any unpaid accrued interest is reversed and charged against interest income. If ultimate repayment of a non-accrual loan or lease is expected, any payments received are applied in accordance with contractual terms. If ultimate repayment is not expected on commercial, commercial real estate, and equipment finance loans and leases, any payment received on a non-accrual loan or lease is applied to principal until the unpaid balance has been fully recovered. Any excess is then credited to interest income when received. If the Company determines, through a current valuation analysis, that principal can be repaid on residential real estate and consumer loans, interest payments may be taken into income as received on a cash basis.

Loans are generally removed from non-accrual status when they become current as to principal and interest or demonstrate a period of performance under contractual terms and, in the opinion of management, are fully collectible as to principal and interest. Pursuant to regulatory guidance, a loan discharged under Chapter 7 of the U.S. bankruptcy code is removed from non-accrual status when the bank expects full repayment of the remaining pre-discharged contractual principal and interest, and had at least six consecutive months of current payments. Refer to Note 4: Loans and Leases for further information.

ALLL is a reserve established through a provision for loan and lease losses charged to expense and represents management’s best estimate of probable losses that may be incurred within the existing loan and lease portfolio as of the balance sheet date. The ALLL consists of three elements: (i) specific valuation allowances established for probable losses on impaired loans and leases; (ii) quantitative valuation allowances calculated using loss experience for like loans and leases with similar characteristics and trends, adjusted, as necessary, to reflect the impact of current conditions; and (iii) qualitative factors determined based on general economic conditions and other factors that may be internal or external to the Company. The reserve level reflects management’s view of trends in losses, current portfolio quality, and present economic, political, and regulatory conditions. The ALLL may be allocated for specific portfolio segments; however, the entire balance is available to absorb credit losses inherent in the total loan and lease portfolio. A charge-off is recorded when all or a portion of the loan or lease is deemed to be uncollectible. While management utilizes its best judgment based on the information available at the time, the ultimate adequacy of the allowance is dependent upon a variety of factors that are beyond the Company’s control, which include the performance of the Company’s portfolio, economic conditions, interest rate sensitivity, and other external factors.

The process for estimating probable losses is based on predictive models that measure the current risk profile of the loan and lease portfolio and combines the measurement with other quantitative and qualitative factors. To measure credit risk for the commercial, commercial real estate, and equipment financing portfolios, the Company employs a dual grade credit risk grading system for estimating the PD and the 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) - (6) are considered pass ratings, and (7) - (10) are considered criticized as defined by the regulatory agencies. Risk ratings, assigned to differentiate risk within the portfolio, are reviewed on an ongoing basis and revised to reflect changes in a borrowers’ 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. A (7) "Special Mention" asset has the potential weakness that, if left uncorrected, may result in deterioration of the repayment prospects for the asset. An (8) "Substandard" asset has a well defined weakness that jeopardizes the full repayment of the debt. An asset rated (9) "Doubtful" has all of the same weaknesses as a substandard credit with the added characteristic that the weakness makes collection or liquidation in full, given current facts, conditions, and values, improbable. Assets classified as (10) "Loss" in accordance with regulatory guidelines are considered uncollectible and charged off.

For residential and consumer loans, the Company considers factors such as past due status, updated FICO scores, employment status, collateral, geography, loans discharged in bankruptcy, and the status of first lien position loans on second lien position loans as credit quality indicators. On an ongoing basis for portfolio monitoring purposes, the Company estimates the current value of property secured as collateral for home equity and residential first mortgage lending products. The estimate is based on home price indices compiled by the S&P/Case-Shiller Home Price Indices. The real estate price data is applied to the loan portfolios taking into account the age of the most recent valuation and geographic area. Back-testing is performed to compare original estimated losses and actual observed losses, resulting in ongoing refinements. The balance resulting from this process together with specific valuation allowances determines the overall reserve level.

Any loan may be charged-off if a loss confirming event has occurred. Loss confirming events usually involve the receipt of specific adverse information about the borrower and may include bankruptcy (unsecured), foreclosure, or receipt of an asset valuation indicating a shortfall between the value of the collateral and the book value of the loan when that collateral asset is the sole source of repayment. The Company generally charges-off commercial loans when it is determined that the specific loan or a portion thereof is uncollectible. This determination is based on facts and circumstances of the individual loans and normally includes considering the viability of the related business, the value of any collateral, the ability and willingness of any guarantors to perform and the overall financial condition of the borrower. The Company generally charges-off residential real estate loans to the estimated fair value of their collateral, net of selling costs, when they become 180 days past due.

Loans and leases are considered impaired when, based on current information and events, it is probable the Company will be unable to collect all amounts due in accordance with the original contractual terms of the loan agreement, including scheduled principal and interest payments. Impairment is evaluated on a pooled basis for smaller-balance homogeneous residential, consumer loans and small business loans. Commercial, commercial real estate, and equipment financing loans and leases over a specific dollar amount and all TDRs are evaluated individually for impairment. A loan identified as a TDR is considered an impaired loan for its entire term, with few exceptions. If a loan is impaired, a specific valuation allowance may be established, and the loan is reported net, at the present value of estimated future cash flows using the loan’s original interest rate or at the fair value of collateral less cost to sell if repayment is expected from collateral liquidation. Interest payments on non-accruing impaired loans are typically applied to principal unless collectability of the principal amount is reasonably assured, in which case interest is recognized on a cash basis. Factors considered by management in determining impairment include payment status, collateral value, discharged bankruptcy, and the likelihood of collecting scheduled principal and interest payments. Refer to Note 4: Loans and Leases for further information.

The reserve for unfunded commitments provides for probable losses inherent with funding the unused portion of legal commitments to lend. The unfunded reserve calculation includes factors that are consistent with the ALLL methodology for funded loans using the PD, LGD, and a draw down factor applied to the underlying borrower risk and facility grades. The reserve for unfunded credit commitments is included within other liabilities in the consolidated balance sheets, and changes in the reserve are reported as a component of other non-interest expense in the consolidated statements of income. Refer to Note 22: Commitments and Contingencies for further information.

A modified loan is considered a TDR when the following two conditions are met: (i) the borrower is experiencing financial difficulty; and (ii) the modification constitutes a concession. The Company considers all aspects of the restructuring in determining whether a concession has been granted, including the borrower's ability to access funds at a market rate. In general, a concession exists when the modified terms of the loan are more attractive to the borrower than standard market terms. Modified terms are dependent upon the financial position and needs of the individual borrower. The most common types of modifications include covenant modifications and forbearance. Loans for which the borrower has been discharged under Chapter 7 bankruptcy are considered collateral dependent TDR, impaired at the date of discharge, and charged down to the fair value of collateral less cost to sell, if management considers that loss potential likely exists.

The Company’s policy is to place consumer loan TDRs, except those that were performing prior to TDR status, on non-accrual status for a minimum period of six months. Commercial TDR are evaluated on a case-by-case basis for determination of whether or not to place them on non-accrual status. Loans qualify for return to accrual status once they have demonstrated performance with the restructured terms of the loan agreement for a minimum of six months. Initially, all TDRs are reported as impaired. Generally, TDRs are classified as impaired loans and reported as TDR for the remaining life of the loan. Impaired and TDR classification may be removed if the borrower demonstrates compliance with the modified terms for a minimum of six months and through a fiscal year-end and the restructuring agreement specifies a market rate of interest equal to that which would be provided to a borrower with similar credit at the time of restructuring. In the limited circumstance that a loan is removed from TDR classification, it is the Company’s policy to continue to base its measure of loan impairment on the contractual terms specified by the loan agreement. Refer to Note 4: Loans and Leases for further information.

Real estate acquired through foreclosure or completion of a deed in lieu of foreclosure and other assets acquired through repossession are recorded at fair value less estimated cost to sell at the date of transfer. Subsequent to the acquisition date, the foreclosed and repossessed assets are carried at the lower of cost or fair value less estimated selling costs and are included within other assets in the consolidated balance sheet. Independent appraisals generally are obtained to substantiate fair value and may be subject to adjustment based upon historical experience or specific geographic trends impacting the property. Upon transfer to OREO the excess of loan balance over fair value less cost to sell is charged off against the ALLL. Subsequent write-downs in value, maintenance costs as incurred, and gains or losses upon sale are charged to non-interest expense in the consolidated statement of income.

Repairs and maintenance costs are charged to non-interest expense as incurred. Property and equipment that is actively marketed for sale is reclassified to assets held for disposition. The cost and accumulated depreciation and amortization relating to property and equipment retired or otherwise disposed of are eliminated, and any resulting losses are charged to non-interest expense. Refer to Note 6: Premises and Equipment for further information.

A right-of-use (ROU) asset and corresponding lease liability is recognized at the lease commencement date when the Company is a lessee. ROU lease assets are included in premises and equipment on the consolidated balance sheet. A ROU asset reflects the present value of the future minimum lease payments adjusted for any initial direct costs, incentives, or other payments prior to the lease commencement date. A lease liability represents a legal obligation to make lease payments and is determined by the present value of the future minimum lease payments discounted using the rate implicit in the lease, or the Company’s incremental borrowing rate. Variable lease payments that are dependent on an index, or rate, are initially measured using the index or rate at the commencement date and are included in the measurement of the lease liability. Renewal options are not included as part of the ROU asset or lease liability unless the option is deemed reasonably certain to exercise.

For real estate leases, lease components and non-lease components are accounted for as a single lease component. For equipment leases, lease and non-lease components are accounted for separately. Operating lease expense is comprised of operating lease costs and variable lease costs, net of sublease income, and is reflected as part of occupancy within non-interest expense in the consolidated statement of income. Operating lease expense is recorded on a straight-line basis. Refer to Note 7: Leasing for further information.

Goodwill represents the excess purchase price of businesses acquired over the fair value of the identifiable net assets acquired and is assigned to specific reporting units. Goodwill is not subject to amortization but rather is evaluated for impairment annually, or more frequently if events occur or circumstances change indicating it would more likely than not result in a reduction of the fair value of a reporting unit below its carrying value.

Goodwill may be evaluated for impairment by performing a qualitative assessment to determine whether it is more likely than not that the fair value of the reporting unit is less than its carrying amount, including goodwill. If the qualitative assessment indicates it is more likely than not that the fair value of the reporting unit is less than its carrying amount, including goodwill, then a quantitative process will be performed that requires the Company to utilize an equally weighted combined income and market approach to arrive at an indicated fair value range for the reporting unit. In Step 1, the fair value of a reporting unit is compared to its carrying amount, including goodwill, to ascertain if a goodwill impairment exists. If the fair value of the reporting unit exceeds its carrying amount, goodwill of the reporting unit is not considered impaired, and it is not necessary to continue to Step 2 of the impairment process. Otherwise, Step 2 is performed where the implied fair value of goodwill is compared to the carrying value of goodwill in the reporting unit. If a reporting unit's carrying value of goodwill exceeds fair value of goodwill, the difference is charged to non-interest expense.

Other intangible assets represent purchased assets that lack physical substance but can be distinguished from goodwill because of contractual or other legal rights, or because it is capable of being sold or exchanged either separately or in combination with a related contract, asset, or liability. Other intangible assets with finite useful lives, such as core deposits and customer relationships, are amortized to non-interest expense over their estimated useful lives and are evaluated for impairment whenever events occur or circumstances change indicating the carrying amount of the asset may not be recoverable. Refer to Note 8: Goodwill and Other Intangible Assets for further information.

These agreements are accounted for as secured financing transactions since Webster maintains effective control over the transferred investment securities and the transfer meets the other criteria for such accounting. Obligations to repurchase the sold investment securities are reflected as a liability in the consolidated balance sheets. The investment securities sold, with agreement to repurchase, to wholesale dealers are transferred to a custodial account for the benefit of the dealer or bank with whom each transaction is executed. The dealers or banks may sell, loan, or otherwise hypothecate such securities to other parties in the normal course of their operations and agree to resell to Webster the same securities at the maturity date of the agreements. Webster also enters into repurchase agreements with Bank customers. The investment securities sold with agreement to repurchase to Bank customers are not transferred but internally pledged to the repurchase agreement transaction. Refer to Note 11: Borrowings for further information.

Revenue from contracts with customers generally comprises non-interest income earned by the Company in exchange for services provided to customers and is recognized when services are complete or as they are rendered. These revenue streams include deposit service fees, wealth and investment services, and an insignificant component of other non-interest income in the consolidated statement of income. The Company identifies the performance obligations included in the contracts with customers, determines the transaction price, allocates the transaction price to the performance obligations, as applicable, and recognizes revenue when performance obligations are satisfied. Services provided over a period of time are typically transferred to customers evenly over the term of the contracts and revenue is recognized evenly over the period services are provided. Contract receivables are included in accrued interest receivable and other assets. Payment terms vary by services offered, and the time between completion of performance obligations and payment is typically not significant. Refer to Note 21: Revenue from Contracts with Customers for further information.

Webster maintains stock compensation plans under which restricted stock, restricted stock units, non-qualified stock options, incentive stock options, or stock appreciation rights may be granted to employees and directors. Share awards are issued from available treasury shares. Share-based compensation cost is recognized over the vesting period, is based on the grant-date fair value, net of a reduction for estimated forfeitures which is adjusted for actual forfeitures as they occur, and is reported as a component of compensation and benefits expense. Awards are generally subject to a 3-year vesting period, while certain conditions provide for a 1-year vesting period. Excess tax benefit or tax deficiency results when tax return deductions differ from recognized compensation cost determined using the grant-date fair value approach for financial statement purposes.

For restricted stock and restricted stock unit awards, fair value is measured using the Company's common stock closing price at the date of grant. For certain performance-based restricted stock awards, fair value is measured using the Monte Carlo valuation methodology, which provides for the 3-year performance period. Awards ultimately vest in a range from zero to 150% of the target number of shares under the grant. Compensation expense is subject to adjustment based on management's assessment of Webster's return on equity performance relative to the target number of shares condition. Stock option awards use the Black-Scholes Option-Pricing Model to measure fair value at the date of grant. Dividends are paid on the time-based shares upon grant and are non-forfeitable, while dividends are accrued on the performance-based awards and paid on vested shares when the performance target is met. Refer to Note 19: Share-Based Plans for further information.

Income tax expense, or benefit, is comprised of two components, current and deferred. The current component reflects taxes payable or refundable for a current period based on applicable tax laws, and the deferred component represents the tax effects of temporary differences between amounts recognized for financial accounting and tax purposes. Deferred tax assets and liabilities reflect the tax effects of such differences that are anticipated to result in taxable or deductible amounts in the future, when the temporary differences reverse. DTAs are recognized if it is more likely than not they will be realized, and may be reduced by a valuation allowance if it is more likely than not that all or some portion will not be realized.

Tax positions that are uncertain but meet a more likely than not recognition threshold are initially and subsequently measured as the largest amount of tax benefit that has a greater than 50% likelihood of being realized upon settlement with a taxing authority that has full knowledge of all relevant information. The determination of whether or not a tax position meets the more likely than not recognition threshold considers the facts, circumstances, and information available at the reporting date and is subject to management's judgment. Webster recognizes interest expense and penalties on uncertain tax positions as a component of income tax expense and recognizes interest income on refundable income taxes as a component of other non-interest income. Refer to Note 9: Income Taxes for further information.

Earnings per common share is presented under the two-class method. Basic earnings per common share is computed by dividing earnings allocated to common shareholders by the weighted-average number of common shares outstanding during the applicable period, excluding outstanding participating securities. Certain unvested restricted stock awards are participating securities as they have non-forfeitable rights to dividends. Diluted earnings per common share is computed using the weighted-average number of shares determined for the basic earnings per common share computation plus the dilutive effect of stock compensation and warrants for common stock using the treasury stock method. A reconciliation of the weighted-average shares used in calculating basic earnings per common share and the weighted-average common shares used in calculating diluted earnings per common share is provided in Note 15: Earnings Per Common Share.

Comprehensive income includes all changes in shareholders’ equity during a period, except those resulting from transactions with shareholders. Comprehensive income consists of net income, and the after-tax effect of the following items: changes in net unrealized gain/loss on securities available for sale, changes in net unrealized gain/loss on derivative instruments, and changes in net actuarial gain/loss and prior service cost for defined benefit pension and other postretirement benefit plans. Comprehensive income is reported in the consolidated statement of shareholders' equity, consolidated statement of comprehensive income, and Note 13: Accumulated Other Comprehensive Loss, Net of Tax.

Derivatives are recognized at fair value, with exchange-traded contracts based on quoted market prices while non-exchange traded contracts are based on dealer quotes, pricing models, discounted cash flow methodologies, or similar techniques for which the determination of fair value may require management judgment or estimation, relating to future rates and credit activities. Derivatives are included in accrued interest receivable and other assets and in accrued expenses and other liabilities on the consolidated balance sheet. Cash flows from derivative financial instruments are included in net cash provided by operating activities on the consolidated cash flow statement.

Derivatives Designated in Hedge Relationships. The Company uses derivatives to hedge exposures, or to modify interest rate characteristics, for certain balance sheet accounts under its interest rate risk management strategy. The Company designates derivatives in qualifying hedge relationships as fair value or cash flow hedges for accounting purposes. Derivative financial instruments receive hedge accounting treatment if they are qualified and properly designated as a hedge and remain highly effective in offsetting changes in the fair value or cash flows attributable to the risk being hedged both at hedge inception and on an ongoing basis throughout the life of the hedge. Quarterly prospective and retrospective assessments are performed to ensure hedging relationships continue to be highly effective. If a hedge relationship were no longer highly effective, hedge accounting would be discontinued.

The change in fair value on a derivative designated and qualifying as a fair value hedge, as well as the offsetting change in fair value on the hedged item attributable to the risk being hedged, is recognized in earnings in the same accounting period. The gain or loss on a derivative designated and qualifying as a cash flow hedge is initially recorded as a component of AOCL and subsequently reclassified to interest income as hedged interest payments are received or to interest expense as hedged interest payments are made in the same period during which the hedged transaction affects earnings.

Offsetting Assets and Liabilities. The Company presents derivative assets and derivative liabilities with the same counterparty and the related variation margin of cash collateral are presented on a net basis in the consolidated balance sheet. Cash collateral relating to the initial margin is included in accrued interest receivable and other assets on the consolidated balance sheet. Securities collateral is not offset. The Company clears all dealer eligible contracts through the Chicago Mercantile Exchange (CME), and has elected to record non-cleared derivative positions subject to a legally enforceable master netting agreement on a net basis.

The Company measures many of its assets and liabilities on a fair value basis, in accordance with ASC Topic 820, "Fair Value Measurement." Fair value is used on a recurring basis for certain assets and liabilities in which fair value is the primary basis of accounting. Examples of these include derivative instruments, available-for-sale securities and loans held for sale where the Company has elected the fair value option. Additionally, fair value is used on a non-recurring basis to evaluate assets or liabilities for impairment. Examples of these include impaired loans and leases, mortgage servicing assets, long-lived assets, goodwill, and loans not originated for sale but subsequently transferred to held for sale, which are accounted for at the lower of cost or fair value. Further information regarding the Company's policies and methodology used to measure fair value is presented in Note 17: Fair Value Measurements.

Webster Bank maintains a noncontributory defined benefit pension plan covering all employees that were participants on or before December 31, 2007. Costs related to this qualified plan, based upon actuarial computations of current and future benefits for eligible employees, are charged to non-interest expense and are funded in accordance with the requirements of the Employee Retirement Income Security Act. The plan is recorded as an asset if over-funded or a liability if under-funded. There is a supplemental retirement plan for select executive level employees that were participants on or before December 31, 2007. There is also a postretirement healthcare benefits plan for certain retired employees.

The purpose of the Update is to better align a company’s risk management and financial reporting for hedging activities with the economic objectives of those activities. The Update expands an entity's ability to hedge non-financial and financial risk components and reduce complexity in hedges of interest rate risk. The guidance eliminates the requirement to separately measure and report hedge ineffectiveness, and generally requires the entire change in fair value of a hedging instrument to be presented in the same income statement line in which the earnings effect of the hedged item is reported.

The Company adopted the Updates during the first quarter of 2019 using the new transition method option that allows the use of effective date, January 1, 2019, as the date of initial application of the new lease accounting standard and to recognize a cumulative-effect adjustment to the opening balance of retained earnings upon adoption. The Company elected the transition relief package of practical expedients which forgoes the requirement to reassess the existence of leases in existing contracts, their lease classification and the accounting treatment of their initial direct costs. As a practical expedient, the Company has also made a policy election to not separate non-lease components from lease components for its real estate leases and instead account for each separate lease components and non-lease components associated with that lease component as a single lease component. The Company will separately account for the lease and non-lease components in its equipment leases. The Company determines whether a contract contains a lease based on whether a contract, or a part of a contract, conveys the right to control the use of an identified asset for a period of time in exchange for consideration. The discount rate used is either the rate implicit in the lease, or when a rate cannot be readily determined an incremental borrowing rate. The incremental borrowing rate is the rate of interest that the Company would have to pay to borrow on a collateralized basis over a similar term and amount equal to the lease payments, in a similar economic environment.

As a result of adopting this Update, the Company recognized $157.2 million of right-of-use asset (ROU) and $178.8 million of lease liability, as of January 1, 2019. The Company also recorded a $513 thousand cumulative-effect adjustment directly to retained earnings as of January 1, 2019 for abandoned leased properties and the remaining deferred gains on sale-leaseback transactions which occurred prior to the date of adoption. Refer to Note 7: Leasing for further information.

The Update aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. The updated guidance also requires an entity to amortize the capitalized implementation costs as an expense over the term of the hosting arrangement and to present in the same income statement line item as the fees associated with the hosting arrangement.

The Update modifies the disclosure requirements on fair value measurements. The updated guidance will no longer require entities to disclose the amount and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy. However, it will require public companies to disclose changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements held at the end of the reporting period and the range and weighted average of significant unobservable inputs used to develop Level 3 measurements.

The Update changes current guidance by eliminating the second step of the goodwill impairment analysis which involves calculating the implied fair value of goodwill determined in the same manner as the amount of goodwill recognized in a business combination upon acquisition. Entities will still have the option to first perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary.

The Updates will replace the existing incurred loss approach for recognizing credit losses with a new credit loss methodology known as the current expected credit loss (CECL) model. The CECL methodology requires earlier recognition of credit losses using a lifetime credit loss measurement approach for financial assets carried at amortized cost. The CECL methodology also requires consideration of a broader range of reasonable and supportable information to determine credit loss estimates.

To implement the new standard, the Company established a project lead and empowered a steering committee comprised of members from different disciplines including Credit, Accounting, Finance, Financial Analytics, Information Technology, and Treasury, as well as specific working groups focused on key components of the development process. Through the working groups, the Company evaluated the effect that the Updates have on its financial statements and related disclosures. The CECL credit models incorporate assumptions used to calculate credit losses over the estimated life of the applicable financial assets and include the impact of forecasted macroeconomic conditions. During the fourth quarter of 2019, the Company continued testing CECL credit models, processes, and controls in parallel with the existing incurred loss approach. The Company is continuing to work on finalizing CECL accounting policies and drafting required disclosures under these Updates.

Adopting the new standard required the Company to make certain policy elections and decisions on how expected losses are measured. Under CECL, the Company will estimate lifetime credit losses based on three portfolio segments: commercial loans and leases, consumer loans and lines of credit, and HTM debt securities. Expected losses within the commercial and consumer portfolio segments will be collectively assessed using PD/LGD models. Expected losses on HTM debt securities will be collectively assessed with separate models for each type of security. Through the Company’s established CECL Committee, policy elections, key assumptions, processes, and models will be reviewed and updated as necessary.

These Updates became effective for the Company on January 1, 2020, at which time the CECL processes, controls, and models became the Company’s primary method for calculating and recording the allowance for credit losses. The Company will adopt the Updates using the modified retrospective approach. Upon adoption of the Updates the Company expects an increase of approximately 30% in its allowance for credit losses, reflected as a reduction, net of tax, to the Company's beginning total shareholders' equity at January 1, 2020. Upon adoption the Company’s allowance for credit losses became reflective of all credit losses expected over the lifetime of the Company’s applicable financial assets. The allowance for credit losses will be based on the composition, characteristics, and credit quality of the loan and securities portfolios as of the reporting date and will include consideration of current economic conditions and reasonable and supportable forecasts at that date. The entire increase in the allowance for credit losses will be reflected in the Company's regulatory capital ratios and will not have a significant impact.
