Note 1: Summary of Significant Accounting Policies

Nature of Operations

Webster Financial Corporation (collectively, with its consolidated subsidiaries, “Webster” or the “Company”) is a bank holding company and financial holding company under the Bank Holding Company Act of 1956, as amended, incorporated under the laws of Delaware in 1986 and headquartered in Waterbury, Connecticut. At September 30, 2015, Webster Financial Corporation's principal asset is all of the outstanding capital stock of Webster Bank, National Association ("Webster Bank").

Webster, through Webster Bank and various non-banking financial services subsidiaries, delivers financial services to individuals, families, and businesses primarily from New York to Massachusetts. Webster provides business and consumer banking, mortgage lending, financial planning, trust, and investment services through banking offices, ATMs, telephone banking, mobile banking, and its internet website (www.websterbank.com). Webster also offers equipment financing, commercial real estate lending, and asset-based lending primarily across the Northeast. On a nationwide basis, through its HSA Bank division, Webster Bank offers and administers health savings accounts, flexible spending accounts, health reimbursement accounts, and commuter benefits.

Basis of Presentation

The accounting and reporting policies of the Company that materially affect its financial statements conform with U.S. Generally Accepted Accounting Principles ("GAAP"). The accompanying unaudited Condensed Consolidated Financial Statements of the Company have been prepared in conformity with the instructions for Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all the information and notes required by GAAP for complete financial statements and should be read in conjunction with the Company's Consolidated Financial Statements, and notes thereto, for the year ended December 31, 2014, included in the Company's Annual Report on Form 10-K filed with the SEC on February 27, 2015.

The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the amounts of assets and liabilities as of the date of the financial statements as well as income and expense during the period. Actual results could differ from those estimates. Operating results for the interim periods disclosed herein are not necessarily indicative of the results that may be expected for the full year or any future period.

Certain prior period amounts have been reclassified to conform to the current year's presentation. These reclassifications had an immaterial effect on net income, comprehensive income, total assets, total liabilities, total shareholders' equity, net cash provided by operating activities, net cash used for investing activities, and net cash provided by financing activities.

Acquisition

On January 13, 2015 (the "acquisition date”), Webster Bank completed its acquisition of the health savings account business of JPMorgan Chase Bank, N.A. The results of the acquisition have been included in the financial statements from the acquisition date. See Note 2: Acquisition for further information.

Modifications to Significant Accounting Policies

Non-accrual loans. Effective during the first quarter of 2015, residential loans that are more than 90 days past due, fully insured against loss, and in the process of collection, remain accruing loans and are reported as 90 days or more past due and accruing. Previously, these loans were placed on non-accrual when payments were 90 days or more past due. For presentation purposes, previously reported amounts have been reclassified to conform to the current year presentation. The change in accounting policy did not have a material impact on the financial statements.

Other intangible assets. Other intangible assets with finite useful lives are amortized to non-interest expense over their estimated useful lives. Effective during the first quarter of 2015, core deposit intangibles resulting from the health savings account acquisition are amortized on an accelerated basis over their estimated useful lives. Core deposit intangibles existing prior to the health savings account acquisition will continue to be amortized on a straight line basis over their remaining estimated useful lives. Intangible assets relating to customer relationships are amortized on a straight line basis over their estimated useful lives.

Recently Adopted Accounting Standards Updates

ASU No. 2014-01 - Investments - Equity Method and Joint Ventures (Topic 323) - "Accounting for Investments in Qualified Affordable Housing Projects (a consensus of the FASB Emerging Issues Task Force)." The Update requires an entity to disclose information about its investments in qualified affordable housing projects and provides an accounting policy election for it to account for such investments using the proportional amortization method. Under that method, the initial cost of an investment is amortized in proportion to its tax credits and other tax benefits as a component of income tax expense or benefit. The decision to apply the proportionate amortization method is to be applied consistently to all such investments. The Company adopted this Update effective January 1, 2015 and retrospectively applied the effects of its accounting policy decision to use the proportional amortization method, as Webster believes presenting the investment performance net of taxes as a component of income tax expense or benefit better represents the economics of such investments. The change had no material effect on the Company's financial statements.

7

ASU No. 2014-04, Receivables - Troubled Debt Restructurings by Creditors (Subtopic 310-40) - "Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure (a consensus of the FASB Emerging Issues Task Force)." The Update clarifies that an in substance repossession or foreclosure occurs, and a creditor is considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan, upon either (i) the creditor obtaining legal title to the residential real estate property upon completion of a foreclosure or (ii) the borrower conveying all interest in the residential real estate property to the creditor to satisfy that loan through completion of a deed in lieu of foreclosure or through a similar agreement. In addition, the Update requires disclosure of both the amount of foreclosed residential real estate property held by the creditor and the recorded investment in consumer mortgage loans collateralized by residential real estate property that are in the process of foreclosure in accordance with local requirements of the applicable jurisdiction. The Update was adopted during the first quarter of 2015, by prospective transition, and did not have a material impact on the Company's financial statements.

ASU No. 2014-11 - Transfers and Servicing (Topic 860) - “Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures.” TheUpdate requires two accounting changes: (i) repurchase-to-maturity transactions are to be accounted for as secured borrowings; and (ii) with respect to repurchase financing arrangements, accounting is required for a transfer of a financial asset contemporaneously with a repurchase agreement with the same counterparty, which will result in secured borrowing accounting for the repurchase agreement. Additionally, disclosure requirements have been expanded to include a disaggregation of collateral used for secured borrowings, and contractual maturity disclosure has been expanded to interim periods. The Update was adopted during the first quarter of 2015 and did not have a material impact on the Company's financial statements.

ASU No. 2014-14, Receivables-Troubled Debt Restructurings by Creditors (Subtopic 310-40) - "Classification of Certain Government-Guaranteed Residential Mortgage Loans upon Foreclosure (a consensus of the FASB Emerging Issues Task Force)." The Update has been issued to reduce diversity in practice in the classification of foreclosed residential mortgage loans held by creditors that are fully guaranteed under certain government programs, including the Federal Housing Administration guarantees. A residential mortgage loan would be derecognized, and a separate other receivable would be recognized upon foreclosure if the loan has both of the following characteristics: (i) the loan has a government guarantee that is not separable from the loan before foreclosure entitling the creditor to the full unpaid principal balance of the loan; and (ii) at the time of foreclosure, the creditor has the intent to make a claim on the guarantee and the ability to recover the full unpaid principal balance of the loan through the guarantee. Notably, upon foreclosure, the separate other receivable would be measured based on the current amount of the loan balance expected to be recovered under the guarantee. The Update was adopted during the first quarter of 2015 and did not have a material impact on the Company's financial statements.

Recently Issued Accounting Standards Updates

ASU No. 2014-09 - Revenue from Contracts with Customers (Topic 606). The Update establishes a single comprehensive model for an entity to recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled, and will supersede nearly all existing revenue recognition guidance, and clarify and converge revenue recognition principles under US GAAP and IFRS. The update outlines five steps to recognizing revenue: (i) identify the contracts with the customer; (ii) identify the separate performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the separate performance obligations; and (v) recognize revenue when each performance obligation is satisfied. The update requires more comprehensive disclosures, relating to quantitative and qualitative information for amounts, timing, the nature and uncertainty of revenue, and cash flows arising from contracts with customers, which will mainly impact construction and high-tech industries. The most significant potential impact to banking entities relates to less prescriptive derecognition requirements on the sale of owned real estate properties. An entity may elect either a full retrospective or a modified retrospective application. ASU No. 2015-14 - Revenue from Contracts with Customers (Topic 606), defers the effective date of Update No. 2014-09 for all entities by one year. The Company will apply the guidance in Update 2014-09 to annual and interim periods beginning after December 15, 2017. The Company intends to adopt the Update during the first quarter of 2018. Adoption is not anticipated to have a material impact on the Company's financial statements.

ASU No. 2015-02 - Consolidation (Topic 810) - "Amendments to the Consolidation Analysis." The Update affects limited partnerships and similar legal entities, the evaluation of fees paid to a decision maker or a service provider as a variable interest, the effect of fee arrangements and related parties on the primary beneficiary determination, and certain investment funds. The Company intends to adopt the Update during the first quarter of 2016. Adoption is not anticipated to have a material impact on the Company's financial statements.

ASU No. 2015-03 - Interest - Imputation of Interest (Subtopic 835-30) - "Simplifying the Presentation of Debt Issuance Costs." The Update simplifies the presentation of debt issuance costs, by requiring that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by the amendments in this Update. An entity should apply the Update on a retrospective basis. The Company intends to adopt the Update during the first quarter of 2016. Adoption is not anticipated to have a material impact on the Company's financial statements.

8

ASU No. 2015-07 - Fair Value Measurement (Topic 820) - "Disclosures for Investments in Certain Entities That Calculate Net Asset Value per Share (or its Equivalent) (a consensus of the FASB Emerging Issues Task Force)." The Update removes the requirement to categorize within the fair value hierarchy all investments for which fair value is measured using the net asset value per share practical expedient. The Update also removes the requirement to make certain disclosures for all investments that are eligible to be measured at fair value using the net asset value per share practical expedient. Rather, those disclosures are limited to investments for which the entity has elected to measure the fair value using that practical expedient. An entity should apply the Update on a retrospective basis. The Company intends to adopt the Update during the first quarter of 2016. Adoption is not anticipated to have a material impact on the Company's financial statements.

ASU No. 2015-12 - Plan Accounting-Defined Benefit Pension Plans (Topic 960), Defined Contribution Pension Plans (Topic 962), Health and Welfare Benefit Plans (Topic 965) - "(Part I) Fully Benefit-Responsive Investment Contracts, (Part II) Plan Investment Disclosures, (Part III) Measurement Date Practical Expedient (consensuses of the Emerging Issues Task Force)." The Update has been issued to (I) designate contract value as the only required measure for fully benefit-responsive investment contracts; (II) simplify and make more effective the investment disclosure requirements under Topic 820 and Topics 960, 962, and 965 for employee benefit plans; and (III) provide a similar measurement date practical expedient for employee benefit plans. The Company intends to adopt the Update during the first quarter of 2016. Adoption is not anticipated to have a material impact on the Company's financial statements.

ASU No. 2015-15 - Interest-Imputation of Interest (Subtopic 835-30) - "Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements - Amendments to SEC Paragraphs Pursuant to Staff Announcement at June 18, 2015 EITF Meeting  (SEC Update)." - The Update amends ASC Subtopic 835-30 to address debt issuance costs associated with line-of-credit arrangements. ASU No. 2015-03, which requires entities to present debt issuance costs, related to a recognized debt liability as a direct deduction from the carrying amount of that debt liability, did not address presentation or subsequent measurement of debt issuance costs related to line-of-credit arrangements. The Update permits an entity to defer and present debt issuance costs as an asset and subsequently amortizing the deferred debt issuance costs ratably over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. The Company intends to adopt the Update during the first quarter of 2016. Adoption is not anticipated to have a material impact on the Company's financial statements.

ASU No. 2015-16 - Business Combinations (Topic 805) - "Simplifying the Accounting for Measurement - Period Adjustments." The Update simplifies the accounting for adjustments made to provisional amounts recognized in a business combination. First, the Update requires that the acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amount is determined. The acquirer also should record, in the same period’s financial statements, the effect on earnings of changes in depreciation, amortization, or other income effects, if any, as a result of the change to the provisional amounts, calculated as if the accounting had been completed at the acquisition date. Second, the Update should be applied prospectively to adjustments to provisional amounts that are identified after December 15, 2015 and that are within the measurement period. Upon transition, an entity would be required to disclose the nature of, and reason for, the change in accounting principle. An entity would provide that disclosure in the first annual period of adoption and in the interim periods within the first annual period. The Company intends to adopt the Update during the first quarter of 2016. Adoption is not anticipated to have a material impact on the Company's financial statements.

Note 2: Acquisition

On January 13, 2015, Webster Bank completed its acquisition of the health savings account business of JPMorgan Chase Bank, N.A. As a result of the acquisition, the Company became the leading administrator of health savings accounts on a nationwide basis. The acquisition significantly augments a source of stable, low cost, long duration deposits.

The acquisition date fair value of the net consideration transferred consisted of the following:

(In thousands)	At January 13, 2015
Cash	$	50,485
Contingent consideration (1)	(5,000		)
Total net consideration transferred	$	45,485

(1) The contingent consideration arrangement entitles the Company to receive a rebate of the premium paid for account attrition that occurs during the eighteen-month period beginning on January 13, 2015, the closing date of the transaction.

The following table summarizes the estimated fair values of the assets acquired and liabilities assumed at the acquisition date:

(In thousands)	At January 13, 2015
Cash	$	1,446,898
Intangible assets	43,000
Total identifiable assets acquired	$	1,489,898

Net assets acquired	$	45,485

The fair value of the acquired identifiable intangible assets includes core deposit intangibles and customer relationships. The Company is in the process of completing its analysis of fair value of the assets acquired and liabilities assumed; thus, the measurements of identifiable intangible assets, goodwill, and contingencies are subject to change. Refer to Note 6: Goodwill and Other Intangible Assets for additional information relating to the initial amounts of goodwill and other intangible assets recognized.

The contingent liability represents an obligation that existed at the acquisition date. Accordingly, Webster assumed the liability as part of the transaction and has accounted for it at fair value.

The following discussions by investment security type, summarize the basis for evaluating if investment securities within the Company’s available-for-sale and held-to-maturity portfolios were other-than-temporarily impaired at September 30, 2015. Unless otherwise noted for an investment security type, management does not intend to sell these investments and has determined, based upon available evidence, that it is more likely than not that the Company will not be required to sell these securities before the recovery of their amortized cost.

Available-for-Sale Impairment Analysis

Agency CMO. There were unrealized losses of $1.2 million on the Company’s investment in agency CMO at September 30, 2015 compared to $1.1 million at December 31, 2014. Unrealized losses were essentially flat at September 30, 2015 compared to December 31, 2014. The contractual cash flows for these investments are performing as expected, and there has been no change in the underlying credit quality. The Company does not consider these securities to be other-than-temporarily impaired at September 30, 2015.

Agency MBS. There were unrealized losses of $10.2 million on the Company’s investment in agency MBS at September 30, 2015 compared to $12.7 million at December 31, 2014. Unrealized losses decreased due to lower market rates which resulted in higher security prices at September 30, 2015 compared to December 31, 2014. These investments are issued by a government or a government-sponsored agency and, therefore, are backed by certain government guarantees, either direct or indirect. There has been no change in the credit quality, and the contractual cash flows are performing as expected. The Company does not consider these securities to be other-than-temporarily impaired at September 30, 2015.

Non Agency CMBS. There were unrealized losses of $1.2 million on the Company’s investment in non-agency CMBS at September 30, 2015 compared to $0.1 million at December 31, 2014. The composition of non-agency CMBS in the available-for-sale portfolio experienced increased market spreads which resulted in greater unrealized losses at September 30, 2015 compared to December 31, 2014. Internal and external metrics are considered when evaluating potential other-than temporary impairment. Internal stress tests are performed on individual bonds to monitor potential losses under stress scenarios. The contractual cash flows for these investments are performing as expected. The Company does not consider these securities to be other-than-temporarily impaired at September 30, 2015.

CLO. There were unrealized losses of $2.7 million on the Company's investments in CLO at September 30, 2015 compared to $1.0 million at December 31, 2014.

For the maturity schedule above, mortgage-backed securities and collateralized loan obligations, which 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 maturity date presentation because borrowers have the right to prepay obligations with or without prepayment penalties. At September 30, 2015, the Company had a carrying value of $946.1 million in callable securities in its CMBS, CLO, and municipal bond portfolios. The Company considers these factors in the evaluation of its interest rate risk profile. These maturities do not reflect actual duration which is impacted by prepayments.

Securities with a carrying value totaling $2.9 billion at September 30, 2015 and December 31, 2014 were pledged to secure public funds, trust deposits, repurchase agreements, and for other purposes, as required or permitted by law. At September 30, 2015 and December 31, 2014, the Company had no investments in obligations of individual states, counties, or municipalities which exceeded 10% of consolidated shareholders’ equity.

Credit Quality Indicators. 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 probability of borrower default and the loss given default. The credit risk grade system assigns a rating to each borrower and to the facility, which together form a Composite Credit Risk Profile (“CCRP”). The credit risk grade system categorizes borrowers by common financial profiles that measure the credit strength of borrowers and facilities by common structural characteristics. The CCRP has 10 grades, with each grade corresponding to a progressively greater risk of default. Grades 1 through 6 are considered pass ratings, and 7 through 10 are 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 the borrowers’ current financial positions and outlooks, risk profiles, and the related collateral and structural positions. Loan officers review updated financial information at least annually for all pass rated loans to assess the accuracy of the risk grade. All criticized loans undergo frequent review and enhanced monitoring of the underlying borrower.

A “Special Mention” (7) credit has the potential weakness that, if left uncorrected, may result in deterioration of the repayment prospects for the asset. “Substandard” (8) assets have a well-defined weakness that jeopardizes the full repayment of the debt. An asset rated “Doubtful” (9) 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 “Loss” (10) in accordance with regulatory guidelines are considered uncollectible and charged off.

The recorded investment in commercial loans, commercial real estate loans, and equipment financing leases segregated by risk rating exposure is as follows:

For residential and consumer loans, the Company considers factors such as updated FICO scores, employment status, home prices, loan to value, 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 both 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 Case-Shiller data indicates trends for Metropolitan Statistical Areas. The trend data is applied to the loan portfolios taking into account the age of the most recent valuation and geographic area.

Troubled Debt Restructurings ("TDRs")

The following table summarizes information for TDRs:

In the three and nine months ended September 30, 2015 and 2014, Webster charged off $1.7 million and $7.6 million and $2.1 million and $10.3 million, respectively, for the portion of TDRs deemed to be uncollectible.

TDRs may be modified by means of extended maturity, below market adjusted interest rates, a combination of rate and maturity, or other means, including covenant modifications, forbearance, loans discharged under Chapter 7 bankruptcy, or other concessions.

(1) Post-modification balances approximate pre-modification balances. The aggregate amount of charge-offs as a result of the restructurings was not significant.

The Company's loan and lease portfolio includes loans that have been restructured into an A-Note/B Note structure as a result of evaluating the cash flow of the borrowers to support repayment. Webster immediately charged off the balances of the B-Notes. The restructuring agreements specify a market interest rate equal to that which would be provided to a borrower with similar credit at the time of restructuring.

The following table provides information on loans and leases modified as TDRs within the previous 12 months and for which there was a payment default during the periods presented:

Note 5: Transfers of Financial Assets and Mortgage Servicing Assets

Transfers of Financial Assets

The Company sells financial assets in the normal course of business, primarily residential mortgage loans sold to government-sponsored enterprises through established programs and securities. The gain or loss on loans sold is included as mortgage banking activities in the accompanying Condensed Consolidated Statements of Income.

The Company may be required to repurchase a loan in the event of certain breaches of the representations and warranties, or in the event of default of the borrower within 90 days of sale, as provided for in the sale agreements. A reserve for loan repurchases provides for estimated losses pertaining to the potential repurchase of loans associated with the Company’s mortgage banking activities. The reserve reflects management’s monthly evaluation of the identity of counterparty, the vintage of the loans sold, the amount of open repurchase requests, specific loss estimates for each open request, the current level of loan losses in similar vintages held in the residential loan portfolio, and estimated recoveries on the underlying collateral. The reserve also reflects management’s expectation of losses from repurchase requests for which the Company has not yet been notified, as the performance of loans sold and the quality of the servicing provided by the acquirer also may impact the reserve. The provision recorded at the time of the loan sale is netted from the gain or loss recorded in mortgage banking activities, while any incremental provision, post loan sale, is recorded in other non-interest expense in the accompanying Condensed Consolidated Statements of Income.

The following table provides a summary of activity in the reserve for loan repurchases:

Note 12: Regulatory Matters

Webster is subject to regulatory capital requirements administered by the Federal Reserve, while Webster Bank is subject to regulatory capital requirements administered by the Office of the Comptroller of the Currency ("OCC"). Regulatory authorities can initiate certain mandatory actions if Webster or Webster Bank fail to meet minimum capital requirements, which could have a direct material effect on the Company’s financial statements. Capital adequacy guidelines and, additionally for banks, prompt corrective action regulations involve quantitative measures of assets, liabilities, and certain off-balance sheet items calculated under regulatory accounting practices. These quantitative measures, to ensure capital adequacy, require minimum amounts and ratios.

Basel III rules enhanced the comprehensive methodology for calculating risk-weighted assets which vary by asset class previously established under Basel I rules. Under Basel III, total risk-based capital is comprised of three categories: Common Equity Tier 1 capital ("CET1 capital"), additional Tier 1 capital, and Tier 2 capital. CET1 capital includes common shareholders' equity, less deductions for goodwill, other intangibles, and certain deferred tax losses. Webster's common shareholders' equity, for purposes of CET1, excludes accumulated other comprehensive components as permitted by the opt-out election taken by Webster upon adoption of BASEL III. Tier 1 capital is comprised of CET1 capital plus perpetual preferred stock, while Tier 2 capital includes qualifying subordinated debt and qualifying allowance for credit losses, that together equal total capital. Basel III became effective on January 1, 2015 for non-advanced approach banks as defined, and all prior period data is based on Basel I rules.

The following table provides information on the capital ratios for Webster Financial Corporation and Webster Bank, N.A.:

Dividend Restrictions

In the ordinary course of business, Webster is dependent upon dividends from Webster Bank to provide funds for its cash requirements, including payments of dividends to shareholders. Banking regulations may limit the amount of dividends that may be paid. Approval by regulatory authorities is required if the effect of dividends declared would cause the regulatory capital of Webster Bank to fall below specified minimum levels, or if dividends declared exceed the net income for that year combined with the undistributed net income for the preceding two years. In addition, the OCC has discretion to prohibit any otherwise permitted capital distribution on general safety and soundness grounds. Dividends paid by Webster Bank to Webster totaled $80 million for both the nine months ended September 30, 2015 and the nine months ended September 30,2014.

Options to purchase 305 thousand shares for the three andnine months ended September 30, 2015 and 785 thousand shares for the three andnine months ended September 30, 2014 were excluded from the calculation of diluted earnings per share because the options’ exercise prices were greater than the average market price of Webster's common stock for the respective periods presented.

Restricted Stock

Non-participating restricted stock awards of 52 thousand shares and 93 thousand shares for the three andnine months ended September 30, 2015, respectively, and 157 thousand shares and 178 thousand shares for the three andnine months ended September 30, 2014, respectively, whose issuance is contingent upon the satisfaction of certain performance conditions, were deemed to be anti-dilutive and, therefore, were excluded from the calculation of diluted earnings per share for the respective periods presented.

Note 14: Derivative Financial Instruments

Risk Management Objective of Using Derivatives

Webster manages economic risks, including interest rate, liquidity, and credit risk by managing the amount, sources, and duration of its debt funding along with the use of interest rate derivative financial instruments. Webster enters into interest rate derivative financial instruments to manage exposure related to business activities that result in the receipt or payment of both future known and uncertain cash amounts determined by interest rates.

Webster’s primary objectives in using interest rate derivatives are to add stability to interest expense and to manage its exposure to interest rate movements. To accomplish these objectives, Webster uses interest rate swaps and interest rate caps as part of its interest rate risk management strategy. Interest rate swaps and caps designated as cash flow hedges are designed to manage the risk associated with a forecasted event or an uncertain variable-rate cash flow. Forward-settle interest rate swaps protect the Company against adverse fluctuations in interest rates by reducing its exposure to variability in cash flows relating to interest payments on forecasted debt issuances.

Interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. Interest rate caps designated as cash flow hedges involve the receipt of variable amounts from a counterparty if interest rates rise above the strike rate on the contract in exchange for payment of an up-front premium.

The effective portion of the change in the fair value of derivatives which are designated as and qualify as cash flow hedges is recorded as accumulated other comprehensive loss ("AOCL") and is subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. During the nine months ended September 30, 2015, such derivatives were used to hedge the variable cash flows associated with existing variable-rate debt and forecasted issuances of debt. The ineffective portion of the change in the fair value of the derivatives is recognized directly in earnings. During the three and nine months ended September 30, 2015 and 2014, the Company recorded no ineffectiveness and immaterial amounts of ineffectiveness in earnings, respectively, attributable to the difference in the effective date of the hedge and the effective date of the debt issuance.

At September 30, 2015, the Company has hedged its exposure to the variability in future cash flows for forecasted transactions over a maximum period of three months, excluding transactions related to the payment of variable interest on existing financial instruments.

Webster is also exposed to changes in the fair value of certain of its fixed-rate obligations due to changes in benchmark interest rates. Webster, on occasion, uses interest rate swaps to manage its exposure to changes in fair value on these obligations attributable to changes in the benchmark interest rates. Interest rate swaps designated as fair value hedges involve the receipt of fixed-rate amounts from a counterparty in exchange for Webster making variable-rate payments over the life of the agreements without the exchange of the underlying notional amount. For a qualifying derivative designated as a fair value hedge, the gain or loss on the derivative, as well as the gain or loss on the hedged item, is recognized in interest expense. Webster did not have interest rate derivative instruments designated as ‘fair value’ hedges at September 30, 2015 and December 31, 2014. There was no impact to interest expense during the three and nine months ended September 30, 2015. During the three and nine months ended September 30, 2014, there was no impact and $1.1 million reduction to interest expense, respectively, related to previous fair value hedges.

Webster has additional interest rate derivatives that do not qualify for hedge accounting and are, therefore, accounted for as free-standing derivatives with changes in fair value recorded in other non-interest income. Webster's derivatives not designated as hedges are not speculative and are used to manage the Company's exposure to interest rate movements and other identified risks but do not meet the strict hedge accounting requirements.

Additional derivative instruments include interest rate swap and cap contracts sold to commercial and other customers who wish to modify loan interest rate sensitivity. These contracts are offset with dealer counterparty transactions structured with matching terms. As a result, there is minimal impact on earnings, except for fee income earned in such transactions which is recorded in other non-interest income.

The Company enters into Risk Participation Agreements ("RPA") as financial guarantees of performance on interest rate swap derivatives. The purchased (asset) or sold (liability) guarantee allows the Company to participate-in (for a fee received) or participate-out (for a fee paid) the risk associated with certain derivative positions executed with the borrower by a lead bank. The RPA guarantee is recorded on the balance sheet at fair value, with changes in fair value recognized each period in other non-interest income.

Other derivatives include foreign currency forward contracts related to lending arrangements and a VISA share swap transaction, neither of which are designated for hedge accounting.

Amounts recorded in AOCL related to cash flow hedges

Amounts for the effective portion of changes in the fair value of derivatives are reclassified to interest expense as interest payments are made on Webster's variable-rate debt. Over the next twelve months, the Company estimates that $2.1 million will be reclassified from AOCL as an increase to interest expense.

Webster records gains and losses related to swap terminations to AOCL. These balances are subsequently amortized into interest expense over the respective terms of the hedged debt instruments. At September 30, 2015, the remaining unamortized loss on the termination of cash flow hedges is $31.3 million. Over the next twelve months, the Company estimates that $8.4 million will be reclassified from AOCL as an increase to interest expense.

Pre-tax amounts included in the Condensed Consolidated Statements of Income and Condensed Consolidated Statements of Comprehensive Income related to interest rate derivatives designated as hedges of cash flows were as follows:

Offsetting Derivatives

Webster has entered into transactions with counterparties that are subject to a master netting agreement. Hedge accounting positions are recorded on a gross basis in other assets for gain positions and in other liabilities for loss positions, while non-hedge accounting net positions are recorded in other assets for a net gain position and in other liabilities for a net loss position in the accompanying Condensed Consolidated Balance Sheets.

Counterparty Credit Risk

Derivative contracts involve the risk of dealing with both bank customers and institutional derivative counterparties and their ability to meet contractual terms. The Company has International Swap Derivative Association ("ISDA") Master agreements, including a Credit Support Annex ("CSA"), with all derivative counterparties. The ISDA Master agreements provide that on each payment date, all amounts otherwise owing the same currency under the same transaction are netted so that only a single amount is owed in that currency. The ISDA provides, if the parties so elect, for such netting of amounts in the same currency among all transactions identified as being subject to such election that have common payment dates and booking offices. Under the CSA, daily net exposure in excess of a negotiated threshold is secured by posted cash collateral. The Company has negotiated a zero threshold with the majority of its approved financial institution counterparties. In accordance with Webster policies, institutional counterparties must be analyzed and approved through the Company’s credit approval process.

The Company’s credit exposure on interest rate derivatives with non-dealer counterparties is limited to the net favorable value, including accrued interest, of all such instruments, reduced by the amount of collateral pledged by the counterparties. The Company's credit exposure related to derivatives with dealer counterparties is significantly mitigated with cash collateral equal to, or in excess of, the market value of the instrument, updated daily.

In accordance with counterparty credit agreements and derivative clearing rules, the Company had approximately $77.2 million in net margin collateral posted with financial counterparties at September 30, 2015, all of which were comprised of margin collateral posted to financial counterparties or DCO. Collateral levels for approved financial institution counterparties are monitored daily and adjusted as necessary. In the event of default, should the collateral not be returned, the exposure would be offset by terminating the transaction.

31

The Company regularly evaluates the credit risk of its counterparties, taking into account the likelihood of default, net exposures, and remaining contractual life, among other related factors. The Company's net current credit exposure relating to interest rate derivatives with Webster Bank customers was $78.2 million at September 30, 2015. In addition, the Company monitors potential future exposure, representing its best estimate of exposure to remaining contractual maturity. The potential future exposure relating to interest rate derivatives with Webster Bank customers totaled $18.7 million at September 30, 2015. The credit exposure is mitigated as transactions with customers are generally secured by the same collateral of the underlying transactions being hedged.

Mortgage Banking Derivatives

Forward sales of mortgage loans and MBS are utilized by Webster in its efforts to manage 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, interest rate lock commitments are generally extended to the borrowers. During the period from commitment date to closing date, Webster is subject to the risk that market rates of interest may change. If market rates rise, investors generally will pay less to purchase such loans causing a reduction in the anticipated gain on sale of the loans and possibly resulting in a loss. In an effort to mitigate such risk, forward delivery sales commitments are established under which Webster agrees to deliver whole mortgage loans to various investors or issue MBS. At September 30, 2015, outstanding rate locks totaled approximately $63.8 million, and the outstanding commitments to sell residential mortgage loans totaled approximately $82.2 million. Forward sales, which include mandatory forward commitments of approximately $79.0 million at September 30, 2015, establish the price to be received upon the sale of the related mortgage loan, thereby mitigating certain interest rate risk. There is, however, still certain execution risk specifically related to Webster’s ability to close and deliver to its investors the mortgage loans it has committed to sell. The interest rate locked loan commitments and forward sales commitments are recorded at fair value, with changes in fair value recorded as non-interest income in the accompanying Condensed Consolidated Statements of Income. The fair value of interest rate locked loan commitments and forward sales commitments resulted in a gain of $0.2 million at September 30, 2015 and a loss of $0.1 million at December 31, 2014, and were recorded as a component of other assets in the accompanying Condensed Consolidated Balance Sheets.

Note 15: Fair Value Measurements

Fair value is 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. Fair value is best determined using quoted market prices. However, in many instances, quoted market prices are not available. In such instances, fair values are determined using appropriate valuation techniques. Various assumptions and observable inputs must be relied upon in applying these techniques. Accordingly, categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. As such, the fair value estimates may not be realized in an immediate transfer of the respective asset or liability.

Fair Value Hierarchy

The three levels within the fair value hierarchy are as follows:

• Level 1: Valuation is based upon unadjusted quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date.

• Level 2: Fair value is calculated using inputs other than quoted market prices that are directly or indirectly observable for the asset or liability. The valuation may rely on 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 (such as interest rates, volatilities, prepayment speeds, credit ratings, etc.), or inputs that are derived principally or corroborated by market data, by correlation, or other means.

• Level 3: Inputs for determining the fair value of the respective assets or liabilities are not observable. Level 3 valuations are reliant upon pricing models and techniques that require significant management judgment or estimation.

Assets and Liabilities Measured at Fair Value on a Recurring Basis

Available-for-Sale Investment Securities. When quoted prices are available in an active market, the Company classifies securities within Level 1 of the valuation hierarchy. Level 1 securities include equity securities in financial institutions and U.S. Treasury Bills.

32

If quoted market prices are not available, the Company classifies securities within Level 2 of the valuation hierarchy, and employs an independent pricing service that utilizes matrix pricing to calculate fair value. Such 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 respective terms and conditions for debt instruments. Management maintains procedures to monitor the pricing service's assumptions and establishes processes to challenge the pricing service's valuations that appear unusual or unexpected. Level 2 securities include agency CMO, agency MBS, agency CMBS, CMBS, CLO, single-issuer trust preferred securities, and corporate debt securities.

Derivative Instruments. 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 values are validated against valuations performed by independent third parties and are classified within Level 2 of the fair value hierarchy. In determining if any fair value adjustment related to credit risk is required, Webster evaluates the credit risk of its counterparties by considering factors such as the likelihood of default by the counterparties, its net exposures, the remaining contractual life, as well as the amount of collateral securing the position. Webster reviews its counterparty exposure on a regular basis, and, when necessary, appropriate business actions are taken to adjust the exposure. When determining fair value, Webster applies the portfolio exception with respect to measuring counterparty credit risk for all of its derivative transactions subject to a master netting arrangement. The change in value of derivative assets and liabilities attributable to credit risk was not significant during the reported periods.

Mortgage Banking Derivatives. Mortgage-backed securities are utilized by the Company in its efforts to manage 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 the period from commitment date to closing date, the Company is subject to the risk that market rates of interest may change. If market rates rise, investors generally will pay less to purchase such loans resulting in a reduction in the gain on sale of the loans or, possibly, a loss. In an effort to mitigate such risk, forward delivery sales commitments are established, under which the Company agrees to 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 and, therefore, classified within Level 2 of the fair value hierarchy.

Investments Held in Rabbi Trust. Investments held in a Rabbi Trust primarily include mutual funds that invest in equity and fixed income securities. Shares of mutual funds are valued based on net asset value, which represents quoted market prices for the underlying shares held in the mutual funds. Therefore, investments held in the Rabbi Trust are classified within Level 1 of the fair value hierarchy. Webster has elected to measure the investments held in the Rabbi Trust at fair value. The Company consolidates the invested assets of the trust along with the total deferred compensation obligations and includes them in other assets and other liabilities, respectively, in the accompanying Condensed Consolidated Balance Sheets. Earnings in the Rabbi Trust, including appreciation or depreciation, are reflected as other non-interest income, and changes in the corresponding liability are reflected as compensation and benefits in the accompanying Condensed Consolidated Statements of Income. The cost basis of the investments held in the Rabbi Trust is $3.9 million as of September 30, 2015.

Alternative Investments. The Company generally records alternative investments at cost, subject to impairment testing. The alternative investments that are carried at cost are considered to be measured at fair value on a non-recurring basis when there is impairment. There are certain funds in which the ownership percentage is greater than 3% and are, therefore, recorded at fair value on a recurring basis based upon the net asset value of the respective fund. Alternative investments are non-public entities that cannot be redeemed since the Company’s investment is distributed as the underlying investments are liquidated. As such, these investments are classified within Level 3 of the fair value hierarchy. The Company has $7.4 million in unfunded commitments remaining for its alternative investments as of September 30, 2015. See the Investment Securities Portfolio section of Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations for additional discussion of the Company's alternative investments.

Contingent Consideration. The contingent consideration arrangement entitles the Company to receive a rebate of the premium paid for account attrition that occurs during the eighteen-month period beginning on January 13, 2015, the closing date of the transaction. The valuation is reliant upon a pricing model and techniques that require significant management judgment or estimation. Therefore, the contingent consideration is classified within Level 3 of the fair value hierarchy. The key assumptions considered in the valuation model are a 2.5% annual growth rate, a 13.0% annual account attrition rate plus approximately 6.0% of shock attrition in 2015, a 16.5% discount rate, and a premium on deposits of 4.5%.

Contingent Liability. The liability valuation is based upon unobservable inputs. Therefore, the contingent liability is classified within Level 3 of the fair value hierarchy. The fair value of the contingency represents the estimated price to transfer the liability between market participants at the measurement date under current market conditions.

Assets Measured at Fair Value on a Non-Recurring Basis

Certain assets are measured at fair value on a non-recurring basis; that is, the assets are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances, for example, when there is evidence of impairment. The following is a description of valuation methodologies used for assets measured on a non-recurring basis.

Loans Held for Sale. Loans held for sale are accounted for at the lower of cost or market and are considered to be recognized at fair value when they are recorded at below cost. The fair value of residential mortgage loans held for sale is based on quoted market prices of similar loans sold in conjunction with securitization transactions. Accordingly, such loans are classified within Level 2 of the fair value hierarchy. On occasion, the loans held for sale portfolio includes commercial loans, which require adjustments for changes in loan characteristics. When observable data is unavailable, such loans are classified within Level 3.

Collateral Dependent Impaired Loans and Leases. Impaired loans and leases for which repayment is expected to be provided solely by the value of the underlying collateral are considered collateral dependent and are valued based on the estimated fair value of such collateral using customized discounting criteria. As such, collateral dependent impaired loans and leases are classified as Level 3 of the fair value hierarchy.

Other Real Estate Owned ("OREO") and Repossessed Assets. The total book value of OREO and repossessed assets was $5.4 million at September 30, 2015. OREO and repossessed assets are accounted for at the lower of cost or market and are considered to be recognized at fair value when they are recorded at below cost. The fair value of OREO is based on independent appraisals or internal valuation methods, less estimated selling costs. The valuation may consider available pricing guides, auction results, and price opinions. Certain assets require assumptions about factors that are not observable in an active market in the determination of fair value; as such, OREO and repossessed assets are classified within Level 3 of the fair value hierarchy.

Mortgage Servicing Assets. Mortgage servicing assets are accounted for at cost, subject to impairment testing. When the carrying cost exceeds fair value, a valuation allowance is established to reduce the carrying cost to fair 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; as such, the primary risk inherent in valuing mortgage servicing assets is the impact of fluctuating interest rates on the servicing revenue stream. Mortgage servicing assets are classified within Level 3 of the fair value hierarchy.

The table below presents the valuation methodology and unobservable inputs for Level 3 assets measured at fair value on a non-recurring basis at September 30, 2015:

(Dollars in thousands)
Asset	Fair Value		Valuation Methodology	Unobservable Inputs	Range of Inputs
Impaired loans and leases	$	22,603	Real Estate Appraisals	Discount for appraisal type	4% - 15%
				Discount for costs to sell	0% - 8%
Other real estate owned	$	1,820	Real Estate Appraisals	Discount for appraisal type	0% - 20%
				Discount for costs to sell	8%
Mortgage servicing assets	$	32,353	Discounted cash flow	Constant prepayment rate	7.4% - 32.4%
				Discount rates	1.4% - 3.4%

Fair Value of Financial Instruments

The Company is required to disclose the estimated fair value of financial instruments, both assets and liabilities, for which it is practicable to estimate fair value. The following is a description of valuation methodologies used for those assets and liabilities.

Cash, Due from Banks, and Interest-bearing Deposits. The carrying amount of cash, due from banks, and interest-bearing deposits is used to approximate fair value, given the short time frame to maturity and, as such, assets do not present unanticipated credit concerns. Cash, due from banks, and interest-bearing deposits are classified within Level 1 of the fair value hierarchy.

Held-to-Maturity Investment Securities. When quoted market prices are not available, the Company employs an independent pricing service to calculate fair value. Such 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 respective terms and conditions for debt instruments. Webster has procedures to monitor the pricing service's assumptions and establishes processes to challenge the pricing service's valuations that appear unusual or unexpected. Held-to-Maturity investments, which include agency CMO, agency MBS, agency CMBS, Municipal, and Private Label MBS securities, are classified within Level 2 of the fair value hierarchy.

Loans and Leases, net. The estimated fair value of loans and leases held for investment is calculated using a discounted cash flow method, using future prepayments and market interest rates inclusive of an illiquidity premium for comparable loans and leases. The associated cash flows are adjusted for credit and other potential losses. Fair value for impaired loans and leases is estimated using the net present value of the expected cash flows. Loans and leases are classified within Level 3 of the fair value hierarchy.

Deposit Liabilities. The fair value of demand deposits, savings accounts, and certain money market deposits is the amount payable on demand at the reporting date. The fair value of fixed-maturity certificates of deposit is estimated using the rates currently offered for deposits of similar remaining maturities. Deposit liabilities are classified within Level 2 of the fair value hierarchy.

Securities Sold Under Agreements to Repurchase and Other Borrowings. The carrying value is an estimate of fair value for those securities sold under agreements to repurchase and other borrowings that mature within 90 days. The fair values of all other borrowings are estimated using discounted cash flow analysis based on current market rates adjusted, as appropriate, for associated credit risks. 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 technique. Discount rates are matched with the time period of the expected cash flow and are adjusted, as appropriate, to reflect credit risk. FHLB advances and long-term debt are classified within Level 2 of the fair value hierarchy.

Long-term debt (3)	226,327		222,723		226,237		227,751

The following adjustments to the carrying amount are not included in the fair value:

(1) Mortgage servicing assets is net of reserves of $32 thousand at September 30, 2015 and $23 thousand at December 31, 2014.

(2) FHLB advances is net of unamortized premiums of $27 thousand at September 30, 2015 and $37 thousand at December 31, 2014.

(3) Long-term debt is net of unamortized discounts of $1.0 million at September 30, 2015 and $1.1 million at December 31, 2014.

Fair value estimates are made at a specific point in time, based on relevant market information and information about the financial instrument. These estimates do not reflect any premium or discount that could result from offering for sale at one time the entire holdings or any part of a particular financial instrument. Fair value estimates are based on judgments regarding future expected loss experience, current economic conditions, risk characteristics of various financial instruments, and other factors. These factors are subjective in nature and involve uncertainties and matters of significant judgment and, therefore, cannot be determined with precision. Changes in assumptions could significantly affect the estimates.

Additional contributions to the Webster Bank Pension Plan will be made as deemed appropriate by management in conjunction with information provided by the Plan’s actuaries.

Note 17: Share-Based Plans

Stock compensation plans

Webster maintains stock compensation plans (collectively, the "Plans"), under which non-qualified stock options, incentive stock options, restricted stock, restricted stock units, or stock appreciation rights may be granted to employees and directors. The Company believes these share awards better align the interests of its employees with those of its shareholders. Stock compensation cost is recognized over the required service vesting period for the awards, based on the grant-date fair value, net of estimated forfeitures, and is included as a component of compensation and benefits reflected in non-interest expense.

The following table provides a summary of stock compensation expense recognized in the accompanying Condensed Consolidated Statements of Income:

(1) Vested for purposes of recording compensation expense.

Time-based restricted stock. Time-based restricted stock awards vest over the applicable service period ranging from one to five years. The Plans limit the number of time-based awards that may be granted to an eligible individual in a calendar year to 100,000 shares. Compensation expense is recorded over the vesting period based on a fair value, which is measured using the Company's common stock closing price at the date of grant.

Performance-based restricted stock. Performance-based restricted stock awards vest after a three year performance period, with share quantity dependent on that performance. Awards granted in 2015 and 2014 vest in a range from zero to 150%, while previous awards vest in a range from zero to 200% of the target number of shares under the grant. The performance-based shares granted in 2015 vest, based 50% upon Webster's ranking for total shareholder return versus Webster's compensation peer group companies and 50% upon Webster's average of return on equity for each year during the three year vesting period. The compensation peer group companies are utilized because they represent the financial institutions that best compare with Webster. The Company records compensation expense over the vesting period, based on a fair value calculated using the Monte-Carlo simulation model, which allows for the incorporation of the performance condition for the 50% of the performance-based shares tied to total shareholder return versus the compensation peer group, and based on a fair value of the market price on the date of grant for the remaining 50% of the performance-based shares tied to Webster's return on equity. 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 options. Stock option awards have an exercise price equal to the market price of Webster's stock on the date of grant and vest over periods ranging from three to four years. Each option grants the holder the right to acquire a share of Webster common stock over a contractual life of up to 10 years. There were 1,507,015 non-qualified stock options and 152,120 incentive stock options outstanding at September 30, 2015.

Note 18: Segment Reporting

Beginning in 2015, Webster’s operations are organized into four reportable segments that represent its core businesses – Commercial Banking, Community Banking, HSA Bank, and Private Banking. Community Banking includes the operating segments of Webster's Personal Banking and Business Banking. With the January 2015 acquisition of the health savings account business of JPMorgan Chase Bank, N.A., the reported revenue of the HSA Bank segment exceeds 10% of the combined revenue of all operating segments. As a result, the HSA Bank and Private Banking segments are disclosed separately. These segments reflect how executive management responsibilities are assigned by each of the core businesses, the products and services provided, and the type of customer served and reflect how discrete financial information is currently evaluated by the chief operating decision maker. The Company’s Treasury unit and consumer liquidating portfolio are included in the Corporate and Reconciling category along with the amounts required to reconcile profitability metrics to GAAP reported amounts. The 2014 segment results have been adjusted for comparability to the 2015 segment presentation.

Webster’s reportable segment results are intended to reflect each segment as if it were a stand-alone business. Webster uses an internal profitability reporting system to generate information by operating segment, which is based on a series of management estimates and allocations regarding funds transfer pricing, provision for loan and lease losses, non-interest expense, 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 reported results of any operating segment do not affect the consolidated financial position or results of operations of Webster as a whole. The full profitability measurement reports, which are prepared for each operating segment, reflect non-GAAP reporting methodologies. The differences between full profitability and GAAP results are reconciled in the Corporate and Reconciling segment.

The Company uses a matched maturity funding concept, called funds transfer pricing (“FTP”), to allocate interest income and interest expense to each business while also transferring the primary interest rate risk exposures to the Corporate and Reconciling category. The allocation process considers the specific interest rate risk and liquidity risk of financial instruments and other assets and liabilities in each line of business. The matched maturity funding concept 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. Loans are assigned an FTP rate for funds used and deposits are assigned an FTP rate for funds provided. This process is executed by the Company’s Financial Planning and Analysis division and is overseen by the Company’s Asset/Liability Committee.

Webster allocates the provision for loan and lease losses to each segment based on management’s estimate of the inherent loss content in each of the specific loan and lease portfolios. Provision expense for certain elements of risk that are not deemed specifically attributable to a reportable segment, such as the provision for the consumer liquidating portfolio, is shown as part of the Corporate and Reconciling segment.

Webster allocates a majority of non-interest expense to each reportable segment using a full-absorption costing process. Costs, including corporate overhead, are analyzed, pooled by process, and assigned to the appropriate reportable segment. Income tax expense is allocated to each reportable segment based on the consolidated effective income tax rate for the period shown.

The following tables present the results for Webster’s reportable segments and the Corporate and Reconciling category, which incorporates the allocation of the provision for loan and lease losses and income tax expense:

Note 19: Commitments and Contingencies

Credit-Related Financial Instruments

The Company offers credit-related financial instruments, in the normal course of business to meet certain financing needs of its customers, that involve off-balance sheet risk. These transactions may include an unused commitment to extend credit, standby letter of credit, or commercial letter of credit. Such transactions 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 September 30, 2015		At December 31, 2014
Commitments to extend credit	$	4,938,617	$	4,376,733
Standby letter of credit	150,375		142,964
Commercial letter of credit	39,214		27,787
Total credit-related financial instruments with off-balance sheet risk	$	5,128,206	$	4,547,484

Commitments to Extend Credit. The Company makes commitments under various terms to lend funds to customers at a future point in time. These commitments include revolving credit arrangements, term loan commitments, and short-term borrowing agreements. Most of these loans have fixed expiration dates or other termination clauses where a fee may be required. Since commitments routinely expire without being funded, or after required availability of collateral occurs, the total commitment amount does not necessarily represent future liquidity requirements.

Standby Letter of Credit.A standby letter of credit commits the Company to make payments on behalf of customers if certain specified future events occur. The Company has recourse against the customer for any amount required to be paid to a third party under a standby letter of credit, which is often part of a larger credit agreement under which security is provided. Historically, a large percentage of standby letters of credit expire without being funded. The contractual amount of a standby letter of credit represents the maximum amount of potential future payments the Company could be required to make, and is the Company's maximum credit risk.

Commercial Letter of Credit.A commercial letter of credit is issued to facilitate either domestic or foreign trade arrangements for customers. As a general rule, drafts are committed to be drawn when the goods underlying the transaction are in transit. Similar to a standby letter of credit, a commercial letter of credit is often secured by an underlying security agreement including the assets or inventory they relate to.

These commitments subject the Company to potential exposure in excess of amounts recorded in the financial statements, and therefore, management maintains a specific reserve for unfunded credit commitments. This reserve is reported as a component of accrued expenses and other liabilities in the accompanying Condensed Consolidated Balance Sheets.

The following table provides a summary of activity in the reserve for unfunded credit commitments:

	Three months ended September 30,				Nine months ended September 30,
(In thousands)	2015		2014		2015			2014
Balance, beginning of period	$	2,007	$	4,749	$	5,151		$	4,384

Balance, end of period	$	2,023	$	5,022	$	2,023		$	5,022

Litigation

Webster is involved in routine legal proceedings occurring in the ordinary course of business and is subject to loss contingencies related to such litigation and claims arising therefrom. Webster evaluates these contingencies based on information currently available, including advice of counsel and assessment of available insurance coverage. Webster establishes an accrual for litigation and claims when a loss contingency is considered probable and the related amount is reasonably estimable. This accrual is periodically reviewed and may be adjusted as circumstances change. Webster also estimates certain loss contingencies for possible litigation and claims, whether or not there is an accrued probable loss. Webster believes it has defenses to all the claims asserted against it in existing litigation matters and intends to defend itself in all matters.

Based upon its current knowledge, after consultation with counsel and after taking into consideration its current litigation accrual, Webster believes that at September 30, 2015 any reasonably possible losses, in addition to amounts accrued, are not material to Webster’s consolidated financial condition. However, in light of the uncertainties involved in such actions and proceedings, there is no assurance that the ultimate resolution of these matters will not significantly exceed the amounts currently accrued by Webster or that the Company’s litigation accrual will not need to be adjusted in future periods. Such an outcome could be material to the Company’s operating results in a particular period, depending on, among other factors, the size of the loss or liability imposed and the level of the Company’s income for that period.

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

The following discussion should be read in conjunction with the Company’s Consolidated Financial Statements and Notes thereto, for the year ended December 31, 2014, included in its 2014 Form 10-K, and in conjunction with the Condensed Consolidated Financial Statements and Notes thereto included in Item 1 of this report. Operating results for the three andnine months ended September 30, 2015 are not necessarily indicative of the results for the full year ending December 31, 2015, or any future period.

Forward-Looking Statements and Factors that Could Affect Future Results

This Quarterly Report on Form 10-Q contains “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements can be identified by words such as “believes”, “anticipates”, “expects”, “intends”, “targeted”, “continue”, “remain”, “will”, “should”, “may”, “plans”, “estimates” and similar references to future periods; however, such words are not the exclusive means of identifying such statements. Examples of forward-looking statements include, but are not limited to: (i) projections of revenues, expenses, income or loss, earnings or loss per share, and other financial items; (ii) statements of plans, objectives and expectations of the Company or its management or Board of Directors; (iii) statements of future economic performance; and (iv) statements of assumptions underlying such statements. Forward-looking statements are based on the Company’s current expectations and assumptions regarding its business, the economy and other future conditions. Because forward-looking statements relate to the future, they are subject to inherent uncertainties, risks and changes in circumstances that are difficult to predict. The Company’s actual results may differ materially from those contemplated by the forward-looking statements, which are neither statements of historical fact nor guarantees or assurances of future performance. Factors that could cause actual results to differ from those discussed in the forward-looking statements include, but are not limited to: (1) local, regional, national and international economic conditions and the impact they may have on us and our customers and our assessment of that impact; (2) volatility and disruption in national and international financial markets; (3) government intervention in the U.S. financial system; (4) changes in the level of non-performing assets and charge-offs; (5) changes in estimates of future reserve requirements based upon the periodic review thereof under relevant regulatory and accounting requirements; (6) adverse conditions in the securities markets that lead to impairment in the value of securities in our investment portfolio; (7) inflation, interest rate, securities market and monetary fluctuations; (8) the timely development and acceptance of new products and services and perceived overall value of these products and services by customers; (9) changes in consumer spending, borrowings and savings habits; (10) technological changes and cyber-security matters; (11) the ability to increase market share and control expenses; (12) changes in the competitive environment among banks, financial holding companies and other financial services providers; (13) the effect of changes in laws and regulations (including laws and regulations concerning taxes, banking, securities and insurance) with which we and our subsidiaries must comply, including the Dodd-Frank Wall Street Reform and Consumer Protection Act; (14) the effect of changes in accounting policies and practices, as may be adopted by the regulatory agencies, as well as the Public Company Accounting Oversight Board, the Financial Accounting Standards Board and other accounting standard setters; (15) the costs and effects of legal and regulatory developments including the resolution of legal proceedings or regulatory or other governmental inquiries and the results of regulatory examinations or reviews; and (16) our success at managing the risks involved in the foregoing items. Any forward-looking statement made by the Company in this Quarterly Report on Form 10-Q speaks only as of the date on which it is made. Factors or events that could cause the Company’s actual results to differ may emerge from time to time, and it is not possible for the Company to predict all of them. The Company undertakes no obligation to publicly update any forward-looking statement, whether as a result of new information, future developments or otherwise, except as may be required by law.

Application of Critical Accounting Policies and Accounting Estimates

The Company’s significant accounting policies are described in Note 1 to the Consolidated Financial Statements included in its 2014 Form 10-K and in Note 1 to the Condensed Consolidated Financial Statements included in Item 1 of this report. The preparation of the Condensed Consolidated Financial Statements in accordance with accounting principles generally accepted in the United States (“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, and expenses, and to disclose contingent assets and liabilities. Actual results could differ from those estimates.

Management has identified accounting for (i) allowance for loan and lease losses, (ii) fair value measurements for valuation of financial instruments and valuation of investments for other-than-temporary impairment, (iii) valuation of goodwill and other intangible assets, (iv) income taxes, and (v) defined benefit pension plans as the Company’s most critical accounting policies in that they are important to the Company’s financial condition and results, and they require management’s subjective and complex judgment as a result of the need to make estimates about the effects of matters that are inherently uncertain. These accounting policies and estimates, including the nature of the estimates and types of assumptions used, are described throughout, Part II, Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations included in Webster's 2014 Form 10-K and, this Item 2.

RESULTS OF OPERATIONS

Summary of Performance

For the three months ended September 30, 2015, Webster’s net income available to common shareholders was $49.5 million, or $0.54 per diluted share, an increase of $1.7 million compared to $47.8 million, or $0.53 per diluted share, for the three months ended September 30, 2014. The $1.7 millionincrease is primarily due to an increase of $10.6 million in net interest income, an increase of $10.5 million in non-interest income, offset by an increase of $15.4 million in non-interest expense, an increase of $3.5 million in the provision for loan and lease losses, and an increase of $1.3 million in income tax expense.

For the nine months ended September 30, 2015, Webster’s net income available to common shareholders was $147.1 million, or $1.60 per diluted share, an increase of $6.3 million compared to $140.8 million, or $1.55 per diluted share, for the nine months ended September 30, 2014. The $6.3 millionincrease is primarily due to an increase of $23.5 million in net interest income and an increase of $30.9 million in non-interest income, partially offset by an increase of $40.0 million in non-interest expense, and an increase of $7.8 million in the provision for loan and lease losses.

Net interest income is the difference between interest income on earning assets, such as loans and investments, and interest expense on liabilities, such as deposits and borrowings, which are used to fund those assets. Net interest income is the Company's largest source of revenue, representing 73.3% of total revenue for the nine months ended September 30, 2015. Net interest margin is the ratio of tax-equivalent net interest income to average earning assets for the period. The level of interest rates and the volume and mix of interest-earning assets and interest-bearing liabilities impact net interest income and net interest margin. Net interest income is affected by changes in interest rates, loan and deposit pricing strategies, competitive conditions, the volume and mix of interest-earning assets and interest-bearing liabilities, as well as the level of non-performing assets. Webster manages the risk of changes in interest rates on net interest income through its Asset/Liability Committee ("ALCO") and through related interest rate risk monitoring and management policies. Four main tools are used for managing interest rate risk: (i) the size, duration and credit risk of the investment portfolio, (ii) the size and duration of the wholesale funding portfolio, (iii) off-balance sheet interest rate contracts, and (iv) the pricing and structure of loans and deposits. ALCO meets at least monthly to make decisions on the investment and funding portfolios based on the economic outlook, the Committee’s interest rate expectations, the risk position, and other factors. See the “Asset/Liability Management and Market Risk” section for further discussion of Webster’s interest rate risk position.

Net interest income totaled $168.0 million for the three months ended September 30, 2015 compared to $157.4 million for the three months ended September 30, 2014, an increase of $10.6 million. The increase in net interest income during the three months ended September 30, 2015 was primarily the result of a strong increase in loans, partially offset by declining reinvestment spreads of earning assets. The associated net interest margin decreased13 basis points to 3.04% during the three months ended September 30, 2015 from 3.17% for the three months ended September 30, 2014. Market interest rates remained at historically low levels during the periods presented.

Net interest income totaled $491.3 million for the nine months ended September 30, 2015 compared to $467.8 million for the nine months ended September 30, 2014, an increase of $23.5 million. The increase in net interest income during the nine months ended September 30, 2015 was primarily the result of a strong increase in loans, partially offset by declining reinvestment spreads of earning assets. The associated net interest margin decreased15 basis points to 3.06% during the nine months ended September 30, 2015 from 3.21% for the nine months ended September 30, 2014. Market interest rates remained at historically low levels during the periods presented.

The table below describes the extent to which changes in interest rates and changes in the volume of interest-earning assets and interest-bearing liabilities have impacted interest income and interest expense during the periods indicated. Information is provided in each category with respect to the impact attributable to changes in volume (change in volume multiplied by prior rate), changes attributable to rates (change in rates multiplied by prior volume), and the total net change. The change attributable to the combined impact of volume and rate has been allocated proportionately to the change due to volume and the change due to rate.

The following table reflects net interest income on a fully tax-equivalent basis:

The loan and lease portfolio comprised 66.9% of the average interest-earning assets at September 30, 2015 compared to 66.5% of the average interest-earning assets at September 30, 2014. The loan and lease portfolio yield decreased11 basis points to 3.73% for the nine months ended September 30, 2015 compared to the loan and lease portfolio yield of 3.84% for the nine months ended September 30, 2014. The decrease in the yield on the average loan and lease portfolio is due to the repayment of higher yielding loans and leases and the addition of lower yielding loans and leases in the current interest rate environment.

Average investments increased$517.9 million during the nine months ended September 30, 2015 compared to the nine months ended September 30, 2014. The investments portfolio comprised 32.9% of the average interest-earning assets at September 30, 2015 compared to 33.4% of the average interest-earning assets at September 30, 2014. The investments portfolio yield decreased27 basis points to 3.04% for the nine months ended September 30, 2015 compared to the investments portfolio yield of 3.31% for the nine months ended September 30, 2014. The decrease in the yield on investment securities is due to low market rates on purchases during the current period and increased balances with lower rates.

Average total deposits increased$2.2 billion during the nine months ended September 30, 2015 compared to the nine months ended September 30, 2014. The increase is due to a $354.4 million increase in non-interest-bearing deposits and an increase of $1.8 billion in interest-bearing deposits. The increase in interest-bearing deposits, and an improved product mix to low-cost deposits, was primarily a result of $1.4 billion in deposits from the health savings account acquisition. The average cost of deposits decreased 3 basis points to 0.26% for the nine months ended September 30, 2015 from 0.29% for the nine months ended September 30, 2014. The decrease in the average cost of deposits is the result of improved product mix and pricing which resulted in a shift from higher costing certificates of deposit to total interest-bearing deposits decreasing to 15.5% for the three months ended September 30, 2015 from 18.8% for the nine months ended September 30, 2014.

Average total borrowings decreased$242.7 million during the nine months ended September 30, 2015 compared to the nine months ended September 30, 2014. Borrowings decreased, even as growth in loans and securities exceeded organic deposit growth and operating cash flows, as cash balances brought on with the health savings account acquisition were utilized to pay down certain short-term Federal Home Loan Bank ("FHLB") advances. Average securities sold under agreements to repurchase and other borrowings decreased$228.0 million, and average FHLB advances increased$20.2 million. The average cost of borrowings increased15 basis points to 1.44% for the nine months ended September 30, 2015 from 1.29% for the nine months ended September 30, 2014. The increase in average cost of borrowings is a result of the pay down of short-term lower cost borrowings.

Cash flow hedges impacted the average cost of borrowings as follows:

Provision for Loan and Lease Losses

Management performs a quarterly review of the loan and lease portfolio to determine the adequacy of the allowance for loan and lease losses. At September 30, 2015, the allowance for loan and lease losses totaled $173.0 million, or 1.14% of total loans and leases, compared to $159.3 million, or 1.15% of total loans and leases, at December 31, 2014.

Several factors are considered when determining the level of the allowance for loan and lease losses, including loan growth, portfolio composition, portfolio risk profile, credit performance, changes in the levels of non-performing loans and leases, and changes in the economic environment. These factors, coupled with current and projected net charge-offs, impact the required level of the provision for loan and lease losses. Total net charge-offs were $7.9 million and $21.8 million for the three and nine months ended September 30, 2015, respectively, compared to $7.9 million and $23.8 million for the three and nine months ended September 30, 2014, respectively.

The provision for loan and lease losses of $13.0 million and $35.5 million for the three and nine months ended September 30, 2015, respectively, increased $3.5 million and $7.8 million, respectively, compared to the three and nine months ended September 30, 2014. The increase in provision for loan and lease losses was due primarily to the increase in loan balances and increase in specific reserves on impaired loans.

See the “Loan and Lease Portfolio” through “Allowance for Loan and Lease Losses Methodology” sections for further details.

Comparison to Prior Year Quarter

Total non-interest income for the three months ended September 30, 2015 was $61.5 million, an increase of $10.6 million, or 20.7%, compared to $50.9 million for the three months ended September 30, 2014. The increase is attributable to increases in deposit service fees and loan related fees, partially offset by a decrease in wealth and investment services.

Deposit service fees increased$8.7 million, or 33.0%, as a result of increased checking account service charges and check card interchange income due to new account growth in the quarter and the acquired health savings accounts.

Loan related fees increased $2.8 million, or 51.6%, primarily as a result of agency and prepayment activity.

Wealth and investment services decreased $1.0 million, or 11.4%, primarily due to an adverse impact on sales production driven by market volatility and revenue reductions tied to lower assets under management.

Comparison to Prior Year to Date

Total non-interest income for the nine months ended September 30, 2015 was $179.2 million, an increase of $30.9 million, or 20.8%, compared to $148.3 million for the nine months ended September 30, 2014. The increase is attributable to increases in deposit service fees, loan related fees, other income, and mortgage banking activities, partially offset by lower gain on sale of investment securities and wealth and investment services.

Deposit service fees increased$24.8 million, or 32.1%, as a result of increased checking account service charges and check card interchange income due to new account growth and the addition of the acquired health savings accounts.

Loan related fees increased$4.9 million, or 32.7%, primarily due to growth in unused line fees, agency activity and prepayment activity.

Other income increased$4.7 million, or 37.6%, due in part to $1.7 million of interest related to income tax refunds and swap income.

Mortgage banking activities increased$2.4 million, or 78.4%, due to higher settlement volume driven by mortgage originations which increased due to refinances tied to low interest rates.

The gain on sale of investment securities decreased$3.8 million, or 87.9%, due to limited sale activity in the current year.

Wealth and investment services income decreased$2.0 million, or 7.5%, due to an adverse impact on sales production driven by market volatility and revenue reductions tied to lower assets under management.

Comparison to Prior Year Quarter

Total non-interest expense for the three months ended September 30, 2015 was $139.9 million, an increase of $15.4 million, or 12.3%, compared to $124.5 million for the three months ended September 30, 2014. The increase is attributable to increases in both compensation and benefits and technology and equipment.

Compensation and benefits increased$6.5 million, or 9.8%, due to increases in base compensation, incentive compensation, an increase in the Company's stock price, year over year, which increased deferred compensation, and additional temporary help attributable to HSA's expanding operations.

Technology and equipment increased$5.9 million, or 38.4%, primarily due to transitional service costs related to HSA's acquisition and implementing HSA's new technology platform.

Comparison to Prior Year to Date

Total non-interest expense for the nine months ended September 30, 2015 was $411.4 million, an increase of $40.0 million, or 10.8%, compared to $371.4 million for the nine months ended September 30, 2014. The increase is attributable to increases in compensation and benefits, technology and equipment, professional and outside services, occupancy and marketing, partially offset by a decrease in other expense.

Compensation and benefits increased$19.4 million, or 9.7%, due to an increase in base compensation and temporary help to support HSA's account growth.

Technology and equipment increased$14.6 million, or 31.7%, primarily due to transitional service costs related to the HSA acquisition and implementation costs associated with the new HSA technology platform.

Professional and outside services increased$1.8 million, or 27.7%, primarily as a result of investment in infrastructure.

Occupancy increased$1.5 million, or 4.1%, in part due to HSA's new building facility and higher snow removal costs.

Marketing increased$1.1 million, or 9.2%, due to higher advertising and promotion related expenses.

Deposit insurance increased $1.0 million, or 5.9%, primarily due to growth in assets which increased the assessment base.

Other expense decreased$1.8 million, or 3.4%, as a result of a favorable adjustment to the unfunded reserve related to a refined estimate of the draw down factor assumption within the reserve and a favorable adjustment related to a reduced deposit insurance assessment for prior years.

51

Income Taxes

Webster recognized income tax expense of $25.1 million and $69.8 million, reflecting effective tax rates of 32.7% and 31.2% for the three andnine months ended September 30, 2015, respectively, compared to $23.8 million and $68.2 million, and 32.1% and 31.4%, for the three andnine months ended September 30, 2014, respectively.

The increase in the effective rate for the three months ended September 30, 2015 principally reflects the effects of increased state and local tax expense in 2015, partially offset by a discrete state tax expense recognized in the three months ended September 30, 2014 of $0.4 million, net.

The decrease in the effective rate for the nine months ended September 30, 2015 principally reflects the $4.4 million reduction in the Company’s valuation allowance applicable to its state deferred tax assets recognized in the three months ended June 30, 2015, partially offset by the effects of increased state and local tax expense in 2015 and the $2.0 million net state tax benefit recognized in the three months ended March 31, 2014.

Segment Results

Beginning in 2015, Webster’s operations are organized into four reportable segments that represent its core businesses – Commercial Banking, Community Banking, HSA Bank, and Private Banking. Community Banking includes the operating segments of Webster's Personal Banking and Business Banking. With the January 2015 acquisition of the health savings account business of JPMorgan Chase Bank, N.A., the reported revenue of the HSA Bank segment exceeds 10% of the combined revenue of all operating segments. As a result, the HSA Bank and Private Banking segments are disclosed separately. These segments reflect how executive management responsibilities are assigned by each of the core businesses, the products and services provided, and the type of customer served and reflect how discrete financial information is currently evaluated by the chief operating decision maker. The Company’s Treasury unit and consumer liquidating portfolio are included in the Corporate and Reconciling category along with the amounts required to reconcile profitability metrics to GAAP reported amounts. The 2014 segment results have been adjusted for comparability to the 2015 segment presentation. See Note 18: Segment Reporting in the Notes to Condensed Consolidated Financial Statements contained elsewhere in this report for a description of the funds transfer pricing and reporting methodologies.

The following tables present summarized net income and balance sheet information for Webster’s reportable segments for the periods presented:

Net interest income increased $3.5 million in the three months ended September 30, 2015 from the three months ended September 30, 2014. The increase is primarily due to greater loan and deposit volumes and lower cost of funds. The provision for loan and lease losses increased $1.2 million in the three months ended September 30, 2015 from the three months ended September 30, 2014. The increase is due to continued  growth in the commercial loan portfolio, coupled with an increase in reserves for impaired loans. Management believes the reserve level is adequate to cover inherent losses in the Commercial Banking portfolio. Non-interest income increased $2.1 million for the three months ended September 30, 2015 from the three months ended September 30, 2014. The increase is primarily due to agency activities. Non-interest expense increased $2.0 million in the three months ended September 30, 2015 from the three months ended September 30, 2014. The increase is primarily due to compensation and benefit costs related to strategic new hires and increased allocated costs.

Net interest income increased $13.5 million in the nine months ended September 30, 2015 from the nine months ended September 30, 2014. The increase is primarily due to greater loan and deposit volumes and lower cost of funds. The provision for loan and lease losses increased $2.5 million in the nine months ended September 30, 2015 from the nine months ended September 30, 2014. Management believes the reserve level is adequate to cover inherent losses in the Commercial Banking portfolio. Non-interest income increased $3.6 million for the nine months ended September 30, 2015 from the nine months ended September 30, 2014, the increase is primarily due to loan related fees. Non-interest expense increased $4.6 million in the nine months ended September 30, 2015 from the nine months ended September 30, 2014. The increase is primarily due to compensation and benefit costs related to strategic new hires and the loss on the sale of an other real estate owned ("OREO") property in March 2015, and increased allocated costs.

Loans increased $621.1 million from December 31, 2014. Loan originations in the three and nine months ended September 30, 2015 and 2014 were $592.3 million and $1.9 billion and $692.1 million and $2.0 billion, respectively. Originations decreased $45.9 million in the nine months ended September 30, 2015 from the comparable period in 2014.

Total deposits increased a modest $15.9 million for the period ended September 30, 2015 compared to December 31, 2014. The increase is primarily due to timing of large corporate deposits.

54

Net interest income increased $1.8 million in the three months ended September 30, 2015 from the three months ended September 30, 2014. The increase is due primarily to growth in both loans and transaction deposits which was partially offset by the effects of the persistent low interest rate environment on the value of deposits. The provision for loan and lease losses increased $3.2 million in the three months ended September 30, 2015 from the three months ended September 30, 2014.The increased level of provision for three months ended September 30, 2015 is the primarily the result of continued growth in the consumer unsecured lending portfolio. Management believes the reserve level at September 30, 2015 is adequate to cover inherent losses in the Community Banking portfolio. Non-interest income decreased $0.4 million in the three months ended September 30, 2015 from the three months ended September 30, 2014, primarily due to a decline in Investment Services revenue which was impacted by market volatility which lowered sales production duringthe quarter. A decrease in the gains on sale of residential mortgages was due to narrower spreads on loan sales. Non-interest expense increased $3.2 million in the three months ended September 30, 2015 from the three months ended September 30, 2014. The increase is primarily due to increases in compensation, benefits, and debit card processing expenses.

Net interest income decreased $1.7 million in the nine months ended September 30, 2015 from the nine months ended September 30, 2014. The decrease is due primarily to the effects of the persistent low interest rate environment on the value of deposits. The provision for loan and lease losses increased $4.7 million in the nine months ended September 30, 2015 from nine months ended September 30, 2014. The increased level of provision for the nine months ended September 30, 2014 is due to the aforementioned growth in the consumer unsecured portfolio, and additional reserve dollars for potential payment shock risk attributable to home equity lines of credit reaching the “end of draw” (i.e., entering the amortization period). Management believes the reserve level at September 30, 2015 is adequate to cover inherent losses in the Community Banking portfolio. Non-interest income increased $3.2 million in the nine months ended September 30, 2015 from the nine months ended September 30, 2014, primarily due to increased gains from the sale of mortgage loans and growth in fees associated with credit and debit cards. Non-interest expense increased $5.8 million in the nine months ended September 30, 2015 from the nine months ended September 30, 2014. The increase is primarily due to increases in compensation and benefits, marketing expenses and increased snow removal costs, which were partially offset by a decrease in amortization expense on intangible assets.

Total loans increased $626.8 million for the period ended September 30, 2015 compared to December 31, 2014. The net increase is related to growth inresidential mortgages, business banking loans, and unsecured personal loans. Loan originations in the three and nine months ended September 30, 2015 and 2014 were $668.2 million and $1.9 billion and $521.3 million and $1.3 billion, respectively. The increase of $619.0 million in originations during the nine months ended September 30, 2015 is primarily due to increases in jumbo loans, increases in residential mortgage originations associated with refinances tied to low interest rates, and a strong spring home purchase season.

Total deposits increased $44.8 million for the period ended September 30, 2015 compared to December 31, 2014, due to growth in business and consumer account balances which was partially offset by a decrease in certificate of deposit balances.

HSA Bank

HSA Bank, a division of Webster Bank, offers health savings accounts, health reimbursement accounts, flexible spending accounts, and other financial solutions for healthcare. These solutions are used in conjunction with high deductible health plans and are offered through employers or directly to consumers. The solutions are distributed nationwide directly and through multiple partnerships.

On January 13, 2015, Webster Bank completed its acquisition of JPMorgan Chase Bank, N.A.'s health savings account business. The acquisition of approximately 829,000 accounts, including approximately $1.4 billion in deposits and $185.0 million in assets under administration, solidifies the HSA Bank division as a leading administrator and depository of health savings accounts with more than 1.6 million accounts and more than $4.3 billion in footings at September 30, 2015.

Net interest income increased $9.0 million in the three months ended September 30, 2015 from the three months ended September 30, 2014. The increase was due to higher HSA Bank's deposit balances and number of accounts as a result of the acquisition and organic growth, partially offset by a lower funds transfer credit. Non-interest income increased $9.4 million in the three months ended September 30, 2015 from the three months ended September 30, 2014. The increases in HSA Bank's deposit balances and number of accounts resulted in an increase in deposit service fees and interchange income. Non-interest expense increased $11.1 million in the three months ended September 30, 2015 from the three months ended September 30, 2014, primarily due to an increase in processing costs to support the organic growth and the acquired health savings accounts.

Net interest income increased $24.4 million in the nine months ended September 30, 2015 from the nine months ended September 30, 2014. The increase was due to higher HSA Bank's deposit balances and number of accounts as a result of the acquisition and organic growth, partially offset by a lower funds transfer credit. Non-interest income increased $26.4 million in the nine months ended September 30, 2015 from the nine months ended September 30, 2014. The increases in HSA Bank's deposit balances and number of accounts resulted in an increase in deposit service fees and interchange income. Non-interest expense increased $31.0 million in the nine months ended September 30, 2015 from the nine months ended September 30, 2014, primarily due to an increase in processing costs to support the organic growth and the acquired health savings accounts.

Total deposits increased $1.8 billionat September 30, 2015 compared to December 31, 2014. The health savings account acquisition in January increased deposits by $1.4 billion, and $400 million is the result of net new deposit growth. Additionally, HSA Bank had $651.7 million in assets under administration through linked brokerage accounts at September 30, 2015 compared to $747.0 millionat December 31, 2014. The $95.3 million decline in linked brokerage balances is driven primarily by two events; the health savings account acquisition in January added $185.0 million in linked brokerage accounts and a custodial only relationship exited in August 2015, reducing linked brokerage accounts by $385.4 million and deposits by $47.9 million.

Net interest income increased $0.4 million in the three months ended September 30, 2015 from the three months ended September 30, 2014. The increase was due to higher loan balances of approximately $108.8 million. The provision for loan and lease losses decreased $0.3 million in the three months ended September 30, 2015 from the three months ended September 30, 2014. The decreased provision expense is due primarily to improvements in the loss forecasts associated with home equity lines and loans and decreased charge-offs. Management believes the reserve level at September 30, 2015 is adequate to cover inherent losses in the portfolio. Non-interest income decreased $0.2 million in the three months ended September 30, 2015 from the three months ended September 30, 2014. The decrease in non-interest income is due to revenue reductions tied to a decline in assets under management valuations resulting from negative market performance in the three months ended September 30, 2015. Non-interest expense increased $0.3 million in the three months ended September 30, 2015 from the three months ended September 30, 2014, primarily due to an increased investment in marketing; consulting related to enhancing investment management systems; occupancy expenses related to the move of the wealth advisory business; and, expenses in support of the increased level of loan production in 2015.

Net interest income increased $0.9 million in the nine months ended September 30, 2015 from the nine months ended September 30, 2014. The increase was due to $108.8 million growth in loan balances compared to the nine months ended September 30, 2014. The provision for loan and lease losses decreased $0.9 million in the nine months ended September 30, 2015 from the nine months ended September 30, 2014. The decreased provision expense is due primarily to improvements in the loss forecasts associated with home equity lines and loans and decreases in charge-offs. Management believes the reserve level at September 30, 2015 is adequate to cover inherent losses in the portfolio. Non-interest income decreased $0.6 million in the nine months ended September 30, 2015 from the nine months ended September 30, 2014. The decrease in non-interest income is due to revenue reductions tied to assets under management outflows associated with March 2014 personnel departures resulting from Private Banking’s strategic shift; coupled with a decline in assets under management valuations resulting from negative market performance in the three months ended September 30, 2015. This decrease more than offset the 7% increase in fee income from the wealth advisory platform. Non-interest expense increased $0.8 million in the nine months ended September 30, 2015 from the comparable period in 2014, primarily due to an increased investment in marketing, consulting related to enhancing investment management systems and occupancy expenses related to the office relocation of the wealth advisory staff and increased expenses related to the increased level of loan production compared to the prior year, partially offset by a one time credit in compensation and benefits related to the aforementioned personnel departures in March 2014.

Total loans were $473.1 million and increased $77.4 million in the nine months ended September 30, 2015, as loan originations and advances outpaced principal paydowns. Loan originations in the three and nine months ended September 30, 2015 and 2014 were $63.9 million and $141.9 million and $32.5 million and $58.0 million, respectively.

Assets under management were $1.4 billionat September 30, 2015 and $1.5 billion at December 31, 2014, and assets under administration were $227.4 millionat September 30, 2015 and $214.7 million at December 31, 2014.

Financial Condition

Webster had total assets of $24.1 billion at September 30, 2015 and $22.5 billion at December 31, 2014. Total loans and leases of $15.0 billion, net of allowance for loan and lease losses of $173.0 million, at September 30, 2015 increased $1.3 billion compared to total loans and leases of $13.7 billion, net of allowance for loan and lease losses of $159.3 million, at December 31, 2014. Total deposits of $17.6 billion at September 30, 2015 increased $1.9 billion compared to total deposits of $15.7 billion at December 31, 2014. Non-interest-bearing deposits decreased1.3%, while interest-bearing deposits increased16.4% during the period.

At September 30, 2015, total shareholders' equity of $2.4 billionincreased$79.7 million compared to total shareholders' equity of $2.3 billion at December 31, 2014. Changes in shareholders' equity for the nine months ended September 30, 2015 included an increase for net income of $153.8 million, partially offset by $3.3 million in other comprehensive loss, $60.1 million in common dividends, $6.7 million in preferred dividends, and repurchases of $16.9 million of common stock. The quarterly cash dividend to common shareholders has been $0.23 per common share since April 20, 2015. See the "Selected Financial Highlights" section and Note 12: Regulatory Matters in the Notes to Condensed Consolidated Financial Statements contained elsewhere in this report for information on Webster’s regulatory capital levels and ratios.

Investment Securities Portfolio

Webster Bank's investment securities portfolio is managed within regulatory guidelines and corporate policy, which include limitations on aspects such as concentrations in and type of investments as well as minimum risk ratings per type of security. The Office of the Comptroller of the Currency may establish additional individual limits on a certain type of investment if the concentration in such investment presents a safety and soundness concern. The holding company also may hold investment securities directly.

Webster maintains, through the Corporate Treasury Unit of the Company, an investment securities portfolio that is primarily structured to provide a source of liquidity for operating needs, to generate interest income, and as a means to manage interest-rate risk. The portfolio is classified into two major categories, available-for-sale and held-to-maturity. The available-for-sale portfolio consists primarily of agency collateralized mortgage obligations ("agency CMO"), agency mortgage-backed securities ("agency MBS"), non-agency commercial mortgage-backed securities ("non-agency CMBS"), and collateralized loan obligations ("CLO"). The held-to-maturity portfolio consists primarily of agency CMO, agency MBS, agency commercial mortgage-backed securities ("agency CMBS"), municipal bonds, and non-agency CMBS. The combined carrying value of investment securities totaled $7.0 billion and $6.7 billion at September 30, 2015 and December 31, 2014, respectively. Available-for-sale securities increased by $221.5 million, primarily due to new purchase activity, offset by principal payments. Held-to-maturity securities increased by $78.3 million, primarily due to the purchases of agency MBS exceeding the portfolio paydowns and calls. On a tax-equivalent basis, the yield in the securities portfolio for the nine months ended September 30, 2015 and 2014 was 3.04% and 3.31%, respectively.

The Company held $2.3 billion in investment securities that are in an unrealized loss position at September 30, 2015. Approximately $1.4 billion of this total has been in an unrealized loss position for less than twelve months, while the remainder, $1.0 billion, has been in an unrealized loss position for twelve months or longer. The total unrealized loss was $33.4 million at September 30, 2015. These investment securities were evaluated by management and were determined not to be other-than-temporarily impaired. The Company does not have the intent to sell these investment securities, and it is more likely than not that it will not have to sell these securities before the recovery of their cost basis. To the extent that credit movements and other related factors influence the fair value of investments, the Company may be required to record impairment charges for other-than-temporary impairment ("OTTI") in future periods.

For the nine months ended September 30, 2015, the Company recorded $82 thousand charge for OTTI on its available-for-sale securities. The amortized cost of available-for-sale securities is net of $3.3 million and $3.7 million of OTTI at September 30, 2015 and December 31, 2014, respectively, related to previously impaired CLO securities identified as Covered Fund investments by Section 619 of the Dodd-Frank Act, commonly known as the Volcker Rule.

The benchmark 10-year U.S. Treasury rate decreased to 2.04% on September 30, 2015 from 2.17% on December 31, 2014. Webster has the ability to use the investment portfolio, as well as interest-rate financial instruments within internal policy guidelines, to hedge and administer interest-rate risk as part of its asset/liability management strategy. See Note 14: Derivative Financial Instruments in the Notes to Condensed Consolidated Financial Statements contained elsewhere in this report for additional information concerning derivative financial instruments.

Alternative Investments

Investments in Private Equity Funds. The Company has investments in private equity funds. These investments, which totaled $10.2 million at September 30, 2015 and December 31, 2014, are included in other assets in the accompanying Condensed Consolidated Balance Sheets. The majority of these funds are held at cost based on ownership percentage in the fund, while some are accounted for at fair value using a net asset value. See a further discussion of fair value in Note 15: Fair Value Measurements in the Notes to Condensed Consolidated Financial Statements contained elsewhere in this report. The Company recognized a net gain of $1.2 million and $2.1 million for the three and nine months ended September 30, 2015, respectively, and a net gain of $0.9 million and $0.7 million for three and nine months ended September 30, 2014, respectively. These amounts are included in other non-interest income in the accompanying Condensed Consolidated Statements of Income.

Other Non-Marketable Investments. The Company holds certain non-marketable investments, which include preferred share ownership in other equity ventures. These investments, which totaled $5.8 million at September 30, 2015 and $6.8 millionDecember 31, 2014, are included in other assets in the accompanying Condensed Consolidated Balance Sheets. These funds are held at cost and subject to impairment testing. The Company recorded income of $27 thousand and $28 thousand and $66 thousand and $67 thousand for the three and nine months ended September 30, 2015 and 2014, respectively, related to these investments. These amounts are included in other non-interest income in the accompanying Condensed Consolidated Statements of Income.

The Volcker Rule prohibits investments in private equity funds and non-public funds that are considered Covered Funds as defined by Section 619 of the Dodd-Frank Act. Conformance with the final rule is required by July 21, 2017 for certain non-compliant Covered Funds, as defined in the regulation. Additional extensions are available if the retention of such ownership interest is necessary to fulfill a contractual obligation of the banking entity. The Company does not expect any material impact to the financial statements related to the Volcker Rule on alternative investments.

Asset Quality

Management maintains asset quality within established risk tolerance levels through its underwriting standards, servicing, and management of loans and leases. Non-performing assets, loan and lease delinquency, and credit loss levels are considered to be key measures of asset quality.

The following table provides key asset quality ratios:

Impaired Loans and Leases

Loans 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 loans of a similar nature. Consumer and residential loans for which the borrower has been discharged in Chapter 7 bankruptcy are considered collateral dependent impaired loans at the date of discharge. Commercial, commercial real estate, and equipment financing loans and leases over a specific dollar amount, risk rated substandard or worse, and non-accruing, and all troubled debt restructurings are evaluated individually for impairment. Impairment may be evaluated at the present value of estimated future cash flows using the original interest rate of the loan or at the fair value of collateral, less estimated selling costs. To the extent that an impaired loan or lease balance is collateral dependent, the Company determines the fair value of the collateral.

For residential and consumer collateral dependent loans, a third-party appraisal is obtained upon loan default. Fair value of the collateral for residential and consumer collateral dependent loans is reevaluated every 180 days, by either a new appraisal or other internal valuation methods. Fair value is also reassessed, with any excess amount charged off, for consumer loans that reach 180 days past due per Federal Financial Institutions Examination Council guidelines. For commercial, commercial real estate, and equipment financing collateral dependent loans and leases, Webster's impairment process requires the Company to determine the fair value of the collateral by obtaining a third-party appraisal or asset valuation, an interim valuation analysis, blue book reference, or other internal methods. Fair value of the collateral for commercial loans is reevaluated quarterly. Whenever the Company has a third-party real estate appraisal performed by independent licensed appraisers, a licensed in-house appraisal officer or qualified reviewer reviews these appraisals for compliance with the Financial Institutions Reform Recovery and Enforcement Act and the Uniform Standards of Professional Appraisal Practice.

A fair value shortfall is recorded as an impairment reserve against the allowance for loan and lease losses. Subsequent to an appraisal or other fair value estimate, should reliable information come to management's attention that the value has declined further, additional impairment may be recorded to reflect the particular situation, thereby increasing the allowance for loan and lease losses. Any impaired loan for which no specific valuation allowance was necessary at September 30, 2015 and December 31, 2014 is the result of either sufficient cash flow or sufficient collateral coverage of the book balance.

At September 30, 2015, there were 1,726 impaired loans and leases with a recorded investment balance of $281.8 million, which included loans and leases of $197.7 million with an impairment allowance of $30.3 million, compared to 1,828 impaired loans and leases with a recorded investment balance of $332.2 million, which included loans and leases of $218.8 million, with an impairment allowance of $25.3 million at December 31, 2014.

Troubled Debt Restructurings ("TDRs")

A modified loan is considered a TDR when two conditions are met: (i) the borrower is experiencing financial difficulties and (ii) the modification constitutes a concession. Modified terms are dependent upon the financial position and needs of the individual borrower. The Company considers all aspects of the restructuring in determining whether a concession has been granted, including the debtor's ability to access market rate funds. In general, a concession exists when the modified terms of the loan are more attractive to the borrower than standard market terms. The most common types of modifications include covenant modifications, forbearance, and/or other concessions. If the modification agreement is violated, the loan is reevaluated to determine if it should be handled by the Company’s Restructuring and Recovery group for resolution, which may result in foreclosure. Loans for which the borrower has been discharged under Chapter 7 bankruptcy are considered collateral dependent TDRs and thus impaired at the date of discharge and charged down to the fair value of collateral less cost to sell.

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 6 months. Commercial TDRs are evaluated on a case-by-case basis for determination of whether or not to place 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 6 months. Initially, all TDRs are reported as impaired. Generally, TDRs are classified as impaired loans and reported as TDRs 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 6 months and through one 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.

Allowance for Loan and Lease Losses Methodology

The allowance for loan and lease losses ("ALLL") and the reserve for unfunded credit commitments are maintained at a level deemed sufficient by management to cover probable losses in the loan and lease portfolios. Executive management reviews and advises on the adequacy of these reserves. The ALLL policy is considered a critical accounting policy.

The quarterly process for estimating probable losses is based on predictive models, the current risk profile of loan portfolios, and other relevant factors. Management judgment and assumptions influence loss estimates and ALLL balances. Management considers factors such as the nature and volume of portfolio growth, national and regional economic conditions and trends, and other internal performance metrics, and how each of these factors is expected to impact near term loss trends. While actual future conditions and realized losses may vary significantly from assumptions, management believes the ALLL is adequate as of September 30, 2015.

Webster’s methodology for assessing an appropriate level of the ALLL includes three key elements:

i. Impaired loans and leases are either analyzed on an individual or pooled basis and assessed for specific reserves based on collateral, cash flow, and probability of re-default specific to each loan or lease;

ii. Loans and leases with similar risk characteristics are segmented into homogeneous pools and modeled using quantitative methods. The commercial portfolio loss estimate is based on the expected loss methodology - specifically, probability of default ("PD"), loss given default ("LGD"), and exposure at default ("EAD"), where PD and LGD are functions of internal risk-ratings. Changes in risk ratings and other risk factors, for both performing and non-performing loans and leases, will affect the calculation of the allowance. Residential and consumer portfolio loss estimates are based on roll rate models. Webster Bank considers other quantitative contributing factors for risks impacting the performance of loan portfolios that are not explicitly included in the quantitative models and may adjust loss estimates based on these factors. Contributing factors may include, but are not limited to, collateral values, unemployment, and other changes in economic activity, and internal performance metrics;

iii. Webster Bank also considers qualitative factors that are not specifically driven by defined metrics but can have an incremental or regressive impact on losses incurred in the current loan and lease portfolio. Examples include staffing levels, credit concentrations, and macro-economic trends. The quantitative and qualitative contributing factors are consistent with interagency regulatory guidance.

Webster Bank has credit policies and procedures in place designed to support loan growth within an acceptable level of risk. Management reviews and approves these policies and procedures on a regular basis. To assist management with its review, reports related to loan production, loan quality, concentrations of credit, loan delinquencies, non-performing loans, and potential problem loans are generated by loan reporting systems.

Commercial loans are underwritten after evaluating and understanding the borrower’s ability to operate and service its debt. Underwriting standards are designed in support for the promotion of relationships rather than transactional banking. Once it is determined that the borrower’s management possesses sound ethics and solid business acumen, the Company examines current and projected cash flows to determine the ability of the borrower to repay obligations as agreed. Commercial and industrial loans are primarily made based on the identified cash flows of the borrower and secondarily on the underlying collateral provided by the borrower. The cash flows of borrowers, however, may not be as expected, and the collateral securing these loans may fluctuate in value. Most commercial and industrial loans are secured by the assets being financed and may incorporate personal guarantees of the principals.

Commercial real estate loans are subject to underwriting standards and processes similar to commercial and industrial loans, in addition to those specific to real estate loans. These loans are viewed primarily as cash flow loans and secondarily as loans secured by real estate. Repayment of these 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. Commercial real estate loans may be adversely affected by conditions in the real estate markets or in the general economy. The Company also utilizes third-party experts to provide insight and guidance about economic conditions and trends affecting its commercial real estate loan portfolio.

Commercial construction loans have unique risk characteristics and are provided to experienced developers/sponsors with strong track records of successful completion and sound financial condition and are underwritten utilizing feasibility studies, independent appraisals, sensitivity analysis of absorption and lease rates, and financial analysis of the developers and property owners. Commercial construction loans are generally based upon estimates of costs and value associated with the complete project. These estimates may be subject to change as the construction project proceeds. In addition, these loans often include partial or full completion guarantees. Sources of repayment for these types of loans may be pre-committed permanent loans from approved long-term lenders, sales of developed property, or an interim loan commitment from the Company until permanent financing is obtained. These loans are closely monitored with on-site inspections by third-party professionals and the Company's internal staff.

Policies and procedures are in place to manage consumer loan risk and are developed and modified, as needed. Policies and procedures, coupled with relatively small loan amounts and predominately collateralized structures spread across many individual borrowers, minimize risk. Trend and outlook reports are reviewed by management on a regular basis. Underwriting factors for 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 and are also influenced by regulatory requirements. Additionally, Webster Bank originates both qualified mortgage ("QM") and non-QM loans as defined by the Consumer Financial Protection Bureau rules that went into effect on January 10, 2014, with appropriate policies, procedures, and underwriting guidelines that include ability-to-repay standards.

At September 30, 2015, the ALLL was $173.0 million, or 1.14% of the total loan and lease portfolio and 108.80% of total non-performing loans and leases. This compares with the ALLL of $159.3 million at December 31, 2014, or 1.15% of the total loan and lease portfolio and 122.62% of total non-performing loans and leases. The net increase of $13.7 million in the reserve at September 30, 2015 compared to December 31, 2014 is primarily due to collateral and cash flow evaluations of loans individually evaluated for impairment and an increase in loan balances collectively evaluated for impairment.

The following table provides an allocation of the ALLL by portfolio segment:

	At September 30, 2015			At December 31, 2014
(Dollars in thousands)	Amount		% (1)	Amount		% (1)
Residential	$	24,306	0.61	$	25,452	0.73
Consumer	43,844		1.65	43,518		1.71
Commercial	67,841		1.64	52,114		1.39
Commercial real estate	31,452		0.82	32,102		0.90
Equipment financing	5,549		1.00	6,078		1.13
Total ALLL	$	172,992	1.14	$	159,264	1.15

(1) Percentage represents allocated ALLL to total loans and leases within the comparable category. However, the allocation of a portion of the ALLL to one category of loans and leases does not preclude its availability to absorb losses in other categories.

The ALLL reserve allocated to the residential loan portfolio at September 30, 2015 decreased $1.1 million compared to December 31, 2014. The decrease was primarily due to the reduction in loss estimates in individually impaired loans with specific reserves.

The ALLL reserve allocated to the consumer portfolio at September 30, 2015 increased $0.3 million compared to December 31, 2014. The decrease was attributable to year-over-year improvements in asset quality.

The ALLL reserve allocated to the commercial portfolio at September 30, 2015 increased $15.7 million compared to December 31, 2014. The increase was driven primarily by an increase in the specific reserves for impaired loans and loan growth. The increase in the specific reserve is primarily attributed to one impaired commercial non mortgage loan.

The ALLL reserve allocated to the commercial real estate portfolio at September 30, 2015 decreased $0.7 million compared to December 31, 2014. The decrease was due to continuing improvement in asset quality, partially offset by loan growth.

The ALLL reserve allocated to the equipment financing portfolio at September 30, 2015 decreased $0.5 million compared to December 31, 2014. The decrease was due to continuing improvement in asset quality.

Net charge-offs for the three and nine months ended September 30, 2015 were $7.9 million and $21.8 million, consisting of $1.3 million and $4.2 million, respectively, in net charge-offs for residential loans, $3.8 million and $9.8 million, respectively, in net charge-offs for consumer loans, $1.3 million and $5.3 million, respectively, in net charge-offs for commercial real estate loans and $1.5 million and $2.7 million, respectively, in net charge-offs for commercial loans. Net charge-offs were offset by equipment financing net recoveries of $32 thousand and $247 thousand for the three and nine months ended September 30, 2015, respectively. Net charge-offs decreased by $18 thousand and $2.1 million, respectively, for the three and nine months ended September 30, 2015 compared to the three and nine months ended September 30, 2014. The decrease in net charge-off activity reflects lower levels of losses, offset somewhat by lower levels of recoveries, coupled with improved portfolio performance and loan quality metrics for the three and nine months ended September 30, 2015. The decrease in the allowance for loan and lease losses year over year reflects improved portfolio quality and economic conditions across all lines of business, effectively reducing estimated probable losses, partially offset by increases in the allowance to support loan growth.

The following table provides a summary of net charge-offs (recoveries) to average loans and leases by category:

	Three months ended September 30,				Nine months ended September 30,

Sources of Funds and Liquidity

Sources of Funds. The primary source of Webster Bank’s cash flows for use in lending and meeting its general operational needs is deposits. Additional sources of funds include FHLB advances and other borrowings, loan and mortgage-backed securities repayments, securities sale proceeds and maturities, and operating activities. While scheduled loan and securities repayments are a relatively stable source of funds, loan and investment security prepayments and deposit inflows are influenced by prevailing interest rates and local economic conditions and are inherently uncertain.

Federal Home Loan Bank and Federal Reserve Bank Stock. Webster Bank is a member of the Federal Home Loan Bank System, which consists of twelve district Federal Home Loan Banks, each subject to the supervision and regulation of the Federal Housing Finance Agency. An activity-based FHLB capital stock investment is required in order for Webster Bank to access advances and other extensions of credit for liquidity and funding purposes. The FHLB capital stock investment is restricted in that there is no market for it, and it can only be redeemed by the FHLB. Webster Bank held $133.6 million and $142.6 million of FHLB capital stock, at September 30, 2015 and December 31, 2014, respectively, for its membership and for outstanding advances and other extensions of credit. On August 4, 2015, the FHLB paid a cash dividend equal to an annual yield of 3.28%.

Additionally, Webster Bank is required to hold Federal Reserve Bank of Boston ("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 Board of Governors of the Federal Reserve System. The FRB capital stock investment is restricted in that there is no market for it, and it can only be redeemed by the FRB. At both September 30, 2015 and December 31, 2014, Webster Bank held $50.7 million of FRB capital stock. The FRB pays a dividend of 6% annualized.

Deposits. Webster Bank offers a wide variety of deposit products for checking and savings (including: ATM and debit card use, direct deposit, ACH payments, combined statements, mobile banking services, internet-based banking, bank by mail, as well as overdraft protection via line of credit or transfer from another deposit account) designed to meet the transactional, savings, and investment needs of our consumer and business customers throughout 163 banking centers within our primary market area.

Webster Bank manages the flow of funds in its deposit accounts and provides a variety of accounts and rates consistent with Federal Deposit Insurance Corporation ("FDIC") regulations. Webster Bank’s Retail Pricing Committee and its Commercial and Institutional Liability Pricing Committee meet regularly to determine pricing and marketing initiatives. Total deposits were $17.6 billion at September 30, 2015 compared to $15.7 billion at December 31, 2014. The increase is predominately related to health savings account deposits, up$1.8 billion largely a result of the acquisition of $1.4 billion in deposits as described in Note 2: Acquisition. Also, see Note 7: Deposits in the Notes to Condensed Consolidated Financial Statements contained elsewhere in this report for additional information.

Borrowings. Utilized as a source of funding for liquidity and interest rate risk management purposes, borrowings primarily consist of FHLB advances and securities sold under agreements to repurchase, whereby securities are delivered to counterparties under an agreement to repurchase the securities at a fixed price in the future. At September 30, 2015 and December 31, 2014, FHLB advances totaled $2.6 billion and $2.9 billion, respectively. Webster Bank had additional borrowing capacity from the FHLB of approximately $1.2 billion at September 30, 2015 compared to $0.7 billion at December 31, 2014. Webster Bank also had additional borrowing capacity at the FRB of $0.9 billion and $0.8 billion at September 30, 2015 and December 31, 2014, respectively. In addition, unpledged securities of $3.9 billion could have been used to increase borrowing capacity, by $3.5 billion at the FHLB or $3.5 billion at the FRB, or alternatively used as collateral for other borrowings such as repurchase agreements, at September 30, 2015.

In addition, Webster Bank may utilize term and overnight Fed funds to meet short-term liquidity needs. The Company's long-term debt consists of senior fixed-rate notes maturing in 2024 and junior subordinated notes maturing in 2033. Total borrowed funds were $3.8 billion at September 30, 2015 compared to $4.3 billion at December 31, 2014. Borrowings represented 15.9% and 19.2% of total assets at September 30, 2015 and December 31, 2014, respectively. The reduction in borrowings was due to using acquired deposits to pay down certain short-term FHLB advances. For additional information, see Note 8: Securities Sold Under Agreements to Repurchase and Other Borrowings, Note 9: Federal Home Loan Bank Advances, and Note 10: Long-Term Debt in the Notes to Condensed Consolidated Financial Statements contained elsewhere in this report.

Liquidity. Webster meets its cash flow requirements at an efficient cost under various operating environments through proactive liquidity management at both the holding company and Webster Bank. Liquidity comes from a variety of cash flow sources such as operating activities, including principal and interest payments on loans and investments, or financing activities, including unpledged securities, which can be utilized to secure funding or sold, and new deposits. Webster is committed to maintaining a strong, increasing base of core deposits to support growth in its loan and lease portfolio. Liquidity is reviewed and managed in order to maintain stable, cost effective funding to promote overall balance sheet strength.

69

Holding Company Liquidity. Webster’s primary source of liquidity at the holding company level is dividends from Webster Bank. To a lesser extent, investment income, net proceeds from investment sales, borrowings, and public offerings may provide additional liquidity. The main uses of liquidity are the payment of principal and interest to holders of senior notes and capital securities, the payment of dividends to preferred and common shareholders, repurchases of Webster’s common stock, and purchases of available-for-sale securities. There are certain restrictions on the payment of dividends by Webster Bank to the holding company, which are described in the section captioned “Supervision and Regulation” in Item 1 of Webster’s 2014 Form 10-K. At September 30, 2015, there was $301.6 million of retained earnings available for the payment of dividends by Webster Bank to the holding company. Webster Bank paid $80 million in dividends to the holding company during the nine months ended September 30, 2015.

Webster periodically repurchases common shares to fund employee compensation plans. In addition, the Company has a common stock repurchase program authorized by the Board of Directors. The Company records the repurchase of shares of common stock at cost based on the settlement date for these transactions. During the nine months ended September 30, 2015, a total of 471,720 shares of common stock were repurchased at a cost of approximately $16.9 million, of which 121,720 shares were purchased to fund employee compensation plans at a cost of approximately $4.3 million, and 350,000 shares were purchased under the common stock repurchase program at a cost of approximately $12.6 million. At September 30, 2015, there was $26.7 million of remaining repurchase authority under the common stock repurchase program.

Webster Bank Liquidity. Webster Bank's primary source of funding is core deposits, consisting of demand, checking, savings, health savings accounts, money market, and time deposits. The primary use of this funding is for loan portfolio growth. Webster Bank had a loan to total deposit ratio of 86.5% and 88.8% at September 30, 2015 and December 31, 2014, respectively.

Webster Bank is required by regulations adopted by the Office of the Comptroller of the Currency ("OCC") to maintain liquidity sufficient to ensure safe and sound operations. Whether liquidity is adequate, as assessed by the OCC, depends on such factors as the overall asset/liability structure, market conditions, competition, and the nature of the institution’s deposit and loan customers. Webster Bank exceeded all regulatory liquidity requirements as of September 30, 2015. Webster has a detailed liquidity contingency plan designed to respond to liquidity concerns in a prompt and comprehensive manner. It is designed to provide early detection of potential problems and details specific actions required to address liquidity stress scenarios.

Applicable OCC regulations require Webster Bank, as a commercial bank, to satisfy certain minimum leverage and risk-based capital requirements. As an OCC regulated commercial institution, it is also subject to a minimum tangible capital requirement. As of September 30, 2015, Webster Bank was in compliance with all applicable capital requirements and exceeded the FDIC requirements for a “well capitalized” institution. See Note 12: Regulatory Matters in the Notes to Condensed Consolidated Financial Statements contained elsewhere in this report for a further discussion of regulatory requirements applicable to Webster and Webster Bank.

The liquidity position of the Company is continuously monitored, and adjustments are made to the balance between sources and uses of funds as deemed appropriate. Management is not aware of any events that are reasonably likely to have a material adverse effect on the Company’s liquidity, capital resources, or operations. In addition, management is not aware of any regulatory recommendations regarding liquidity, which, if implemented, would have a material adverse effect on the Company.

Off-Balance Sheet Arrangements

Webster engages in a variety of financial transactions that, in accordance with GAAP, are not recorded in the financial statements or are recorded in amounts that differ from the notional amounts. Such transactions are utilized in the normal course of business, for general corporate purposes or for customer financing needs. Corporate purpose transactions are structured to manage credit, interest rate, and liquidity risks, or to optimize capital. Customer transactions are structured to manage their funding requirements or facilitate certain trade arrangements. These transactions give rise to, in varying degrees, elements of credit, interest rate, and liquidity risk. For the nine months ended September 30, 2015, Webster did not engage in any off-balance sheet transactions that would have a material effect on its financial condition.

Asset/Liability Management and Market Risk

An effective asset/liability management process must balance the risks and rewards from both short and long-term interest rate risks in determining management strategy and action. To facilitate and manage this process, Webster has an ALCO. The primary goal of ALCO is to manage interest rate risk to maximize net income and net economic value over time in changing interest rate environments subject to Board approved risk limits. The Board sets policy limits for earnings at risk for parallel ramps in interest rates over twelve months of plus and minus 100, 200 and 300 basis points. Webster was within Board policy for all scenarios. Economic value or “equity at risk” limits are set for parallel shocks in interest rates of plus and minus 100, 200 and 300 basis points. Based on the historic lows in short-term interest rates at September 30, 2015 and December 31, 2014, the declining interest rate scenarios for both the earnings at risk for parallel ramps and the equity at risk for parallel shocks have been temporarily suspended per ALCO policy. ALCO also regularly reviews earnings at risk scenarios for non-parallel changes in rates, as well as longer-term earnings at risk for up to four years in the future.

Management measures interest rate risk using simulation analysis to calculate earnings and equity at risk. These risk measures are quantified using simulation software from one of the leading firms in the field of asset/liability modeling. Key assumptions relate to the behavior of interest rates and spreads, prepayment speeds, and the run-off of deposits. From such simulations, interest rate risk is quantified, and appropriate strategies are formulated and implemented.

Earnings at risk is defined as the change in earnings (excluding provision for loan and lease losses and income tax expense) due to changes in interest rates. Interest rates are assumed to change up or down in a parallel fashion, and earnings results are compared to a flat rate scenario as a base. The flat rate scenario holds the end of the period yield curve constant over the twelve month forecast horizon. Earnings simulation analysis incorporates assumptions about balance sheet changes such as asset and liability growth, loan and deposit pricing, and changes to the mix of assets and liabilities. It is a measure of short-term interest rate risk. Equity at risk is defined as the change in the net economic value of assets and liabilities due to changes in interest rates compared to a base net economic value. Equity at risk analyzes sensitivity in the present value of cash flows over the expected life of existing assets, liabilities, and off-balance sheet contracts. It is a measure of the long-term interest rate risk to future earnings streams embedded in the current balance sheet.

Asset sensitivity is defined as earnings or net economic value increasing compared to a base scenario when interest rates rise and decreasing when interest rates fall. In other words, assets are more sensitive to changing interest rates than liabilities and, therefore, re-price faster. Likewise, liability sensitivity is defined as earnings or net economic value decreasing compared to a base scenario when interest rates rise and increasing when interest rates fall.

Key assumptions underlying the present value of cash flows include the behavior of interest rates and spreads, asset prepayment speeds, and attrition rates on deposits. Cash flow projections from the model are compared to market expectations for similar collateral types and adjusted based on experience with Webster Bank's own portfolio. The model's valuation results are compared to observable market prices for similar instruments whenever possible. The behavior of deposit and loan customers is studied using historical time series analysis to model future customer behavior under varying interest rate environments.

The equity at risk simulation process uses multiple interest rate paths generated by an arbitrage-free trinomial lattice term structure model. The Base Case rate scenario, against which all others are compared, uses the month-end LIBOR/Swap yield curve as a starting point to derive forward rates for future months. Using interest rate swap option volatilities as inputs, the model creates multiple rate paths for this scenario with forward rates as the mean. In shock scenarios, the starting yield curve is shocked up or down in a parallel fashion. Future rate paths are then constructed in a similar manner to the Base Case.

Cash flows for all instruments are generated using product specific prepayment models and account specific system data for properties such as maturity date, amortization type, coupon rate, repricing frequency, and repricing date. The asset/liability simulation software is enhanced with a mortgage prepayment model and a Collateralized Mortgage Obligation database. Instruments with explicit options such as caps, floors, puts and calls, and implicit options such as prepayment and early withdrawal ability require such a rate and cash flow modeling approach to more accurately quantify value and risk. On the asset side, risk is impacted the most by mortgage loans and mortgage-backed securities, which can typically prepay at any time without penalty and may have embedded caps and floors. In the loan portfolio, floors are a benefit to interest income in this low rate environment. Floating-rate loans at floors pay a higher interest rate than a loan at a fully indexed rate without a floor, as with a floor there is a limit on how low the interest rate can fall. As market rates rise, however, the interest rate paid on these loans does not rise until the fully indexed rate rises through the contractual floor. On the liability side, there is a large concentration of customers with indeterminate maturity deposits who have options to add or withdraw funds from their accounts at any time. Webster Bank also has the option to change the interest rate paid on these deposits at any time.

Webster's earnings at risk model incorporates net interest income, non-interest income and expense items, some of which vary with interest rates. These items include mortgage banking income, servicing rights, cash management fees, and derivative mark-to-market adjustments.

71

Four main tools are used for managing interest rate risk: (i) the size and duration of the investment portfolio, (ii) the size and duration of the wholesale funding portfolio, (iii) off-balance sheet interest rate contracts, and (iv) the pricing and structure of loans and deposits. ALCO meets at least monthly to make decisions on the investment and funding portfolios based on the economic outlook, the Committee's interest rate expectations, the risk position, and other factors. ALCO delegates pricing and product design responsibilities to individuals and sub-committees but monitors and influences their actions on a regular basis.

Various interest rate contracts, including futures and options, interest rate swaps, and interest rate caps and floors can be used to manage interest rate risk. These interest rate contracts involve, to varying degrees, credit risk and interest rate risk. Credit risk is the possibility that a loss may occur if a counterparty to a transaction fails to perform according to the terms of the contract. The notional amount of interest rate contracts is the amount upon which interest and other payments are based. The notional amount is not exchanged, and therefore, should not be taken as a measure of credit risk. See Note 14: Derivative Financial Instruments in the Notes to Condensed Consolidated Financial Statements contained elsewhere in this report for additional information.

Certain derivative instruments, primarily forward sales of mortgage-backed securities, are utilized by Webster Bank in its efforts to manage risk of loss associated with its mortgage banking activities. Prior to closing and funds disbursement, an interest-rate lock commitment is generally extended to the borrower. During such time, Webster Bank is subject to risk that market rates of interest may change impacting pricing on loan sales. In an effort to mitigate this risk, forward delivery sales commitments are established, thereby setting the sales price.

The following table summarizes the estimated impact that gradual parallel changes in income of 100 and 200 basis points, over a twelve month period starting September 30, 2015 and December 31, 2014, might have on Webster’s net interest income ("NII") for the subsequent twelve month period compared to NII assuming no change in interest rates:

NII	-200bp	-100bp	+100bp	+200bp
September 30, 2015	N/A	N/A	1.5%	3.2%
December 31, 2014	N/A	N/A	1.8%	3.7%

The following table summarizes the estimated impact that gradual parallel changes in interest rates of 100 and 200 basis points, over a twelve month period starting September 30, 2015 and December 31, 2014, might have on Webster’s pre-tax, pre-provision earnings ("PPNR") for the subsequent twelve month period compared to PPNR assuming no change in interest rates:

PPNR	-200bp	-100bp	+100bp	+200bp
September 30, 2015	N/A	N/A	1.6%	3.9%
December 31, 2014	N/A	N/A	2.7%	5.7%

Interest rates are assumed to change up or down in a parallel fashion, and NII and PPNR results in each scenario are compared to a flat rate scenario as a base. The flat rate scenario holds the end of period yield curve constant over a twelve month forecast horizon. The flat rate scenario as of September 30, 2015 and December 31, 2014 assumed a Fed Funds rate of 0.25%. Asset sensitivity for both NII and PPNR has declined on September 30, 2015 as compared to December 31, 2014. The declines were due to increased residential loan portfolio balances, increased investment balances due to the acquisition of the health savings account business of JPMorgan Chase Bank, N.A., and decreased forecast prepay speeds in the investment and residential loan portfolios, partially offset by increased demand deposit and HSA deposit balances. PPNR sensitivity was further reduced by the expiration of the Fed Funds futures position as of June 30, 2015 which impacts PPNR but not NII. Since the Fed Funds rate was at 0.25% on September 30, 2015, the -100 and -200 basis point scenarios have been excluded.

Webster can also hold futures, options, and forward foreign currency contracts to minimize the price volatility of certain assets and liabilities. Changes in the market value of these positions are recognized in earnings.

The following table summarizes the estimated impact that immediate non-parallel changes in income might have on Webster’s NII for the subsequent twelve month period starting September 30, 2015 and December 31, 2014:

NII	Short End of the Yield Curve				Long End of the Yield Curve
	-100bp	-50bp	+50bp	+100bp	-100bp	-50bp	+50bp	+100bp
September 30, 2015	N/A	N/A	—%	0.4%	(4.6)%	(2.0)%	1.8%	3.1%
December 31, 2014	N/A	N/A	(0.1)%	0.2%	(5.5)%	(2.4)%	2.0%	3.8%

The following table summarizes the estimated impact that immediate non-parallel changes in interest rates might have on Webster’s PPNR for the subsequent twelve month period starting September 30, 2015 and December 31, 2014:

PPNR	Short End of the Yield Curve				Long End of the Yield Curve
	-100bp	-50bp	+50bp	+100bp	-100bp	-50bp	+50bp	+100bp
September 30, 2015	N/A	N/A	(1.0)%	(1.2)%	(8.5)%	(3.6)%	3.3%	5.8%
December 31, 2014	N/A	N/A	(0.3)%	(0.1)%	(9.8)%	(4.1)%	3.6%	6.8%

72

The 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 of less than eighteen months, and the long end as terms of greater than eighteen months. These results above reflect the annualized impact of immediate rate changes. The actual impact can be uneven during the year especially in the short end scenarios where asset yields tied to Prime or LIBOR change immediately, while certain deposit rate changes take more time.

Sensitivity to the short end of the yield curve for NII was essentially unchanged from December 31, 2014 as increased residential loan and investment balances were partially offset by increased demand deposit and HSA deposit balances. Sensitivity to the short end of the yield curve for PPNR at September 30, 2015 was more negative than at December 31, 2014 due primarily to the expiration of the Fed Funds futures position as of June 30, 2015.

Sensitivity to decreases in the long end of the yield curve was less negative than at December 31, 2014 in both NII and PPNR due to decreased forecast prepayment speeds in the residential loan and investment portfolios.

Conversely, sensitivity to increases in the long end of the yield curve was less positive than December 31, 2014 in both NII and PPNR due to decreased forecast prepayment speeds in the residential loan and investment portfolios.

The following table summarizes the estimated economic value of assets, liabilities, and off-balance sheet contracts at September 30, 2015 and December 31, 2014 and the projected change to economic values if interest rates instantaneously increase or decrease by 100 basis points:

	Book Value		Estimated Economic Value		Estimated Economic Value Change
(Dollars in thousands)					-100 bp	+100 bp
September 30, 2015
Assets	$	24,069,782	$	23,873,890	N/A	$	(442,215	)
Liabilities	21,667,237		21,116,315		N/A	(563,218		)
Total	$	2,402,545	$	2,757,575	N/A	$	121,003
Net change as % base net economic value						4.4		%
December 31, 2014
Assets	$	22,533,172	$	22,388,119	N/A	$	(423,429	)
Liabilities	20,210,357		19,799,495		N/A	(455,452		)
Total	$	2,322,815	$	2,588,624	N/A	$	32,023
Net change as % base net economic value						1.2		%

Changes in economic value can be best described using duration. Duration is a measure of the price sensitivity of financial instruments for small changes in interest rates. For fixed-rate instruments, it can also be thought of as the weighted-average expected time to receive future cash flows. For floating-rate instruments, it can be thought of as the weighted-average expected time until the next rate reset. The longer the duration, the greater the price sensitivity for given changes in interest rates. Floating-rate instruments may have durations as short as one day and, therefore, have very little price sensitivity due to changes in interest rates. Increases in interest rates typically reduce the value of fixed-rate assets as future discounted cash flows are worth less at higher discount rates. A liability's value decreases for the same reason in a rising rate environment. A reduction in value of a liability is a benefit to Webster.

Duration gap is the difference between the duration of assets and the duration of liabilities. A duration gap near zero implies that the balance sheet is matched and would exhibit no change in estimated economic value for a small change in interest rates. Webster's duration gap was negative0.1 years at September 30, 2015. At December 31, 2014, the duration gap was negative0.8 years. A negative duration gap implies that liabilities are longer than assets and, therefore, they have more price sensitivity than assets and will reset their interest rates slower than assets. Consequently, Webster's net estimated economic value would generally be expected to increase when interest rates rise as the benefit of the decreased value of liabilities would more than offset the decreased value of 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 longer term absent the effects of new business booked in the future. The change in Webster's duration gap is due primarily to the increase in demand deposit and HSA deposit balances as of September 30, 2015.

These estimates assume that management does not take any action to mitigate any positive or negative effects from changing interest rates. The earnings and economic values estimates are subject to factors that could cause actual results to differ. Management believes that Webster's interest rate risk position at September 30, 2015 represents a reasonable level of risk given the current interest rate outlook. Management, as always, is prepared to act in the event that interest rates do change rapidly.

Impact of Inflation and Changing Prices

The Condensed Consolidated Financial Statements and related data presented herein have been prepared in accordance with GAAP, which requires the measurement of financial position and operating results in terms of historical dollars without considering changes in the relative purchasing power of money over time due to inflation.

Unlike most industrial companies, substantially all of the assets and liabilities of a banking institution are monetary in nature. As a result, interest rates have a more significant impact on Webster's performance than the effects of general levels of inflation. Interest rates do not necessarily move in the same direction or in the same magnitude as the price of goods and services.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Information regarding quantitative and qualitative disclosures about market risk appears in the Asset/Liability Management and Market Risk section of Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

ITEM 4. CONTROLS AND PROCEDURES

As of September 30, 2015, the Company carried out an evaluation, under the supervision and with the participation of the Company's management, including its Chief Executive Officer and its Chief Financial Officer, of the effectiveness of the Company's disclosure controls and procedures (as defined in Rules 13a-15(e) or 15d-15(e) of the Securities Exchange Act of 1934). Based on this evaluation, the Company's Chief Executive Officer and Chief Financial Officer concluded that the Company's disclosure controls and procedures were effective as of September 30, 2015 for recording, processing, summarizing, and reporting the information the Company is required to disclose in the reports it files under the Securities Exchange Act of 1934, within the time periods specified in SEC rules and forms. There were no changes made in the Company’s internal control over financial reporting that occurred during the period covered by this report that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

PART II - OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

From time to time, Webster and its subsidiaries are subject to certain legal proceedings and claims in the ordinary course of business. Management presently believes that the ultimate outcome of these proceedings, individually and in the aggregate, will not be material to Webster or its consolidated financial position. Webster 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. Legal proceedings are subject to inherent uncertainties, and unfavorable rulings could occur that could cause Webster to adjust its litigation accrual or could have, individually or in the aggregate, a material adverse effect on its business, financial condition, or operating results.

ITEM 1A. RISK FACTORS

During the nine months ended September 30, 2015, there were no material changes to the risk factors previously disclosed in Webster's Annual Report on Form 10-K for the year ended December 31, 2014.

ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

Issuer Purchases of Equity Securities

The following table provides information with respect to any purchase of equity securities of Webster common stock made by or on behalf of Webster or any “affiliated purchaser,” as defined in Rule 10b-18(a)(3) under the Securities Exchange Act of 1934, during the three months ended September 30, 2015:

Period	Total Number of Shares Purchased (1)	Average Price Paid Per Share		Total Number of Shares Purchased as Part of Publicly Announced Plans or Programs	Maximum Dollar Amount Available for Repurchase Under the Plans or Programs (1)		Total Number of Warrants Purchased (2)	Average Price Paid Per Warrant
July 1-31, 2015	960	$	38.94	—	$	36,633,443	—	$	—
August 1-31, 2015	268,661	37.00		268,591	26,695,115		1,210	18.65
September 1-30, 2015	5,712	35.35		—	26,695,115		—	—
Total	275,333	36.97		268,591	26,695,115		1,210	18.65

(1) On December 6, 2012, the Company announced that its Board of Directors had approved the current stock repurchase program which authorizes management to repurchase, in open market or privately negotiated transactions, subject to market conditions and other factors, up to a maximum of $100 million of common stock, and will remain in effect until fully utilized or until modified, superseded, or terminated.

Of the total number of shares purchased during the three months ended September 30, 2015, 6,742 shares were purchased outside of the repurchase program, at market prices, to fund equity compensation plans.

(2) On June 3, 2011, the Company announced that, with approval from its Board of Directors, it had repurchased a significant number of the warrants issued as part of Webster's participation in the U.S. Treasury's Capital Purchase Program in a public auction conducted on behalf of the U.S. Treasury. The Board approved plan provides for additional repurchases from time-to-time, in open market or privately negotiated transactions, as permitted by securities laws and other legal requirements. As of September 30, 2015, 69,105 outstanding warrants remain to purchase the Company's common stock, that trade on the New York Stock Exchange under the symbol "WBS WS," which carry an exercise price of $18.28 per share and expire on November 21, 2018.

Restrictions on Dividends

Holders of the Company's common stock are entitled to receive such dividends as the Board of Directors may declare out of funds legally available for such payments. Also, as a bank holding company, the ability to declare and pay dividends is dependent on certain federal regulatory considerations. See Note 12: Regulatory Matters in the Notes to Condensed Consolidated Financial Statements contained elsewhere in this report for additional information.

Since December 4, 2012, the Company has 5,060,000 outstanding Depository Shares, each representing 1/1000th interest in a share of 6.40% Series E Non-Cumulative Perpetual Preferred Stock, par value $0.01 per share, with a liquidation preference of $25,000 per share (or $25 per depository share) ("Series E Preferred Stock"). The Series E Preferred Stock is redeemable at Webster's option, in whole or in part, on December 15, 2017, or any dividend payment date thereafter, or in whole but not in part, upon a "regulatory capital treatment event" as defined in the Prospectus Supplement. The terms of the Series E Preferred Stock prohibit the Company from declaring or paying any cash dividends on its common stock, unless Webster has declared and paid full dividends on the Series E Preferred Stock for the most recently completed dividend period.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]

Share-Based Plans

Share-Based Plans

Stock compensation plans

Webster maintains stock compensation plans (collectively, the "Plans"), under which non-qualified stock options, incentive stock options, restricted stock, restricted stock units, or stock appreciation rights may be granted to employees and directors. The Company believes these share awards better align the interests of its employees with those of its shareholders. Stock compensation cost is recognized over the required service vesting period for the awards, based on the grant-date fair value, net of estimated forfeitures, and is included as a component of compensation and benefits reflected in non-interest expense.

The following table provides a summary of stock compensation expense recognized in the accompanying Condensed Consolidated Statements of Income:

	Three months ended September 30,				Nine months ended September 30,
(In thousands)	2015		2014		2015		2014
Stock options	$	73	$	167	$	305	$	943

Total stock compensation expense	$	3,007	$	2,243	$	8,283	$	7,793

The following table provides a summary of unrecognized stock compensation expense:

	At September 30, 2015
(Dollars in thousands)	Unrecognized Compensation Expense		Weighted-Average Period To Be Recognized

(1) Vested for purposes of recording compensation expense.

Time-based restricted stock. Time-based restricted stock awards vest over the applicable service period ranging from one to five years. The Plans limit the number of time-based awards that may be granted to an eligible individual in a calendar year to 100,000 shares. Compensation expense is recorded over the vesting period based on a fair value, which is measured using the Company's common stock closing price at the date of grant.

Performance-based restricted stock. Performance-based restricted stock awards vest after a three year performance period, with share quantity dependent on that performance. Awards granted in 2015 and 2014 vest in a range from zero to 150%, while previous awards vest in a range from zero to 200% of the target number of shares under the grant. The performance-based shares granted in 2015 vest, based 50% upon Webster's ranking for total shareholder return versus Webster's compensation peer group companies and 50% upon Webster's average of return on equity for each year during the three year vesting period. The compensation peer group companies are utilized because they represent the financial institutions that best compare with Webster. The Company records compensation expense over the vesting period, based on a fair value calculated using the Monte-Carlo simulation model, which allows for the incorporation of the performance condition for the 50% of the performance-based shares tied to total shareholder return versus the compensation peer group, and based on a fair value of the market price on the date of grant for the remaining 50% of the performance-based shares tied to Webster's return on equity. 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 options. Stock option awards have an exercise price equal to the market price of Webster's stock on the date of grant and vest over periods ranging from three to four years. Each option grants the holder the right to acquire a share of Webster common stock over a contractual life of up to 10 years. There were 1,507,015 non-qualified stock options and 152,120 incentive stock options outstanding at September 30, 2015.

Accordingly, they do not include all the information and notes required by GAAP for complete financial statements and should be read in conjunction with the Company's Consolidated Financial Statements, and notes thereto, for the year ended December 31, 2014, included in the Company's Annual Report on Form 10-K filed with the SEC on February 27, 2015.

The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the amounts of assets and liabilities as of the date of the financial statements as well as income and expense during the period. Actual results could differ from those estimates. Operating results for the interim periods disclosed herein are not necessarily indicative of the results that may be expected for the full year or any future period.

Certain prior period amounts have been reclassified to conform to the current year's presentation. These reclassifications had an immaterial effect on net income, comprehensive income, total assets, total liabilities, total shareholders' equity, net cash provided by operating activities, net cash used for investing activities, and net cash provided by financing activities.

Acquisition

On January 13, 2015 (the "acquisition date”), Webster Bank completed its acquisition of the health savings account business of JPMorgan Chase Bank, N.A. The results of the acquisition have been included in the financial statements from the acquisition date. See Note 2: Acquisition for further information.

Modifications to Significant Accounting Policies

Non-accrual loans. Effective during the first quarter of 2015, residential loans that are more than 90 days past due, fully insured against loss, and in the process of collection, remain accruing loans and are reported as 90 days or more past due and accruing. Previously, these loans were placed on non-accrual when payments were 90 days or more past due. For presentation purposes, previously reported amounts have been reclassified to conform to the current year presentation. The change in accounting policy did not have a material impact on the financial statements.

Other intangible assets. Other intangible assets with finite useful lives are amortized to non-interest expense over their estimated useful lives. Effective during the first quarter of 2015, core deposit intangibles resulting from the health savings account acquisition are amortized on an accelerated basis over their estimated useful lives. Core deposit intangibles existing prior to the health savings account acquisition will continue to be amortized on a straight line basis over their remaining estimated useful lives. Intangible assets relating to customer relationships are amortized on a straight line basis over their estimated useful lives.

Recently Adopted Accounting Standards Updates

ASU No. 2014-01 - Investments - Equity Method and Joint Ventures (Topic 323) - "Accounting for Investments in Qualified Affordable Housing Projects (a consensus of the FASB Emerging Issues Task Force)." The Update requires an entity to disclose information about its investments in qualified affordable housing projects and provides an accounting policy election for it to account for such investments using the proportional amortization method. Under that method, the initial cost of an investment is amortized in proportion to its tax credits and other tax benefits as a component of income tax expense or benefit. The decision to apply the proportionate amortization method is to be applied consistently to all such investments. The Company adopted this Update effective January 1, 2015 and retrospectively applied the effects of its accounting policy decision to use the proportional amortization method, as Webster believes presenting the investment performance net of taxes as a component of income tax expense or benefit better represents the economics of such investments. The change had no material effect on the Company's financial statements.

ASU No. 2014-04, Receivables - Troubled Debt Restructurings by Creditors (Subtopic 310-40) - "Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure (a consensus of the FASB Emerging Issues Task Force)." The Update clarifies that an in substance repossession or foreclosure occurs, and a creditor is considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan, upon either (i) the creditor obtaining legal title to the residential real estate property upon completion of a foreclosure or (ii) the borrower conveying all interest in the residential real estate property to the creditor to satisfy that loan through completion of a deed in lieu of foreclosure or through a similar agreement. In addition, the Update requires disclosure of both the amount of foreclosed residential real estate property held by the creditor and the recorded investment in consumer mortgage loans collateralized by residential real estate property that are in the process of foreclosure in accordance with local requirements of the applicable jurisdiction. The Update was adopted during the first quarter of 2015, by prospective transition, and did not have a material impact on the Company's financial statements.

ASU No. 2014-11 - Transfers and Servicing (Topic 860) - “Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures.” TheUpdate requires two accounting changes: (i) repurchase-to-maturity transactions are to be accounted for as secured borrowings; and (ii) with respect to repurchase financing arrangements, accounting is required for a transfer of a financial asset contemporaneously with a repurchase agreement with the same counterparty, which will result in secured borrowing accounting for the repurchase agreement. Additionally, disclosure requirements have been expanded to include a disaggregation of collateral used for secured borrowings, and contractual maturity disclosure has been expanded to interim periods. The Update was adopted during the first quarter of 2015 and did not have a material impact on the Company's financial statements.

ASU No. 2014-14, Receivables-Troubled Debt Restructurings by Creditors (Subtopic 310-40) - "Classification of Certain Government-Guaranteed Residential Mortgage Loans upon Foreclosure (a consensus of the FASB Emerging Issues Task Force)." The Update has been issued to reduce diversity in practice in the classification of foreclosed residential mortgage loans held by creditors that are fully guaranteed under certain government programs, including the Federal Housing Administration guarantees. A residential mortgage loan would be derecognized, and a separate other receivable would be recognized upon foreclosure if the loan has both of the following characteristics: (i) the loan has a government guarantee that is not separable from the loan before foreclosure entitling the creditor to the full unpaid principal balance of the loan; and (ii) at the time of foreclosure, the creditor has the intent to make a claim on the guarantee and the ability to recover the full unpaid principal balance of the loan through the guarantee. Notably, upon foreclosure, the separate other receivable would be measured based on the current amount of the loan balance expected to be recovered under the guarantee. The Update was adopted during the first quarter of 2015 and did not have a material impact on the Company's financial statements.

Recently Issued Accounting Standards Updates

ASU No. 2014-09 - Revenue from Contracts with Customers (Topic 606). The Update establishes a single comprehensive model for an entity to recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled, and will supersede nearly all existing revenue recognition guidance, and clarify and converge revenue recognition principles under US GAAP and IFRS. The update outlines five steps to recognizing revenue: (i) identify the contracts with the customer; (ii) identify the separate performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the separate performance obligations; and (v) recognize revenue when each performance obligation is satisfied. The update requires more comprehensive disclosures, relating to quantitative and qualitative information for amounts, timing, the nature and uncertainty of revenue, and cash flows arising from contracts with customers, which will mainly impact construction and high-tech industries. The most significant potential impact to banking entities relates to less prescriptive derecognition requirements on the sale of owned real estate properties. An entity may elect either a full retrospective or a modified retrospective application. ASU No. 2015-14 - Revenue from Contracts with Customers (Topic 606), defers the effective date of Update No. 2014-09 for all entities by one year. The Company will apply the guidance in Update 2014-09 to annual and interim periods beginning after December 15, 2017. The Company intends to adopt the Update during the first quarter of 2018. Adoption is not anticipated to have a material impact on the Company's financial statements.

ASU No. 2015-02 - Consolidation (Topic 810) - "Amendments to the Consolidation Analysis." The Update affects limited partnerships and similar legal entities, the evaluation of fees paid to a decision maker or a service provider as a variable interest, the effect of fee arrangements and related parties on the primary beneficiary determination, and certain investment funds. The Company intends to adopt the Update during the first quarter of 2016. Adoption is not anticipated to have a material impact on the Company's financial statements.

ASU No. 2015-03 - Interest - Imputation of Interest (Subtopic 835-30) - "Simplifying the Presentation of Debt Issuance Costs." The Update simplifies the presentation of debt issuance costs, by requiring that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by the amendments in this Update. An entity should apply the Update on a retrospective basis. The Company intends to adopt the Update during the first quarter of 2016. Adoption is not anticipated to have a material impact on the Company's financial statements.

ASU No. 2015-07 - Fair Value Measurement (Topic 820) - "Disclosures for Investments in Certain Entities That Calculate Net Asset Value per Share (or its Equivalent) (a consensus of the FASB Emerging Issues Task Force)." The Update removes the requirement to categorize within the fair value hierarchy all investments for which fair value is measured using the net asset value per share practical expedient. The Update also removes the requirement to make certain disclosures for all investments that are eligible to be measured at fair value using the net asset value per share practical expedient. Rather, those disclosures are limited to investments for which the entity has elected to measure the fair value using that practical expedient. An entity should apply the Update on a retrospective basis. The Company intends to adopt the Update during the first quarter of 2016. Adoption is not anticipated to have a material impact on the Company's financial statements.

ASU No. 2015-12 - Plan Accounting-Defined Benefit Pension Plans (Topic 960), Defined Contribution Pension Plans (Topic 962), Health and Welfare Benefit Plans (Topic 965) - "(Part I) Fully Benefit-Responsive Investment Contracts, (Part II) Plan Investment Disclosures, (Part III) Measurement Date Practical Expedient (consensuses of the Emerging Issues Task Force)." The Update has been issued to (I) designate contract value as the only required measure for fully benefit-responsive investment contracts; (II) simplify and make more effective the investment disclosure requirements under Topic 820 and Topics 960, 962, and 965 for employee benefit plans; and (III) provide a similar measurement date practical expedient for employee benefit plans. The Company intends to adopt the Update during the first quarter of 2016. Adoption is not anticipated to have a material impact on the Company's financial statements.

ASU No. 2015-15 - Interest-Imputation of Interest (Subtopic 835-30) - "Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements - Amendments to SEC Paragraphs Pursuant to Staff Announcement at June 18, 2015 EITF Meeting  (SEC Update)." - The Update amends ASC Subtopic 835-30 to address debt issuance costs associated with line-of-credit arrangements. ASU No. 2015-03, which requires entities to present debt issuance costs, related to a recognized debt liability as a direct deduction from the carrying amount of that debt liability, did not address presentation or subsequent measurement of debt issuance costs related to line-of-credit arrangements. The Update permits an entity to defer and present debt issuance costs as an asset and subsequently amortizing the deferred debt issuance costs ratably over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. The Company intends to adopt the Update during the first quarter of 2016. Adoption is not anticipated to have a material impact on the Company's financial statements.

ASU No. 2015-16 - Business Combinations (Topic 805) - "Simplifying the Accounting for Measurement - Period Adjustments." The Update simplifies the accounting for adjustments made to provisional amounts recognized in a business combination. First, the Update requires that the acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amount is determined. The acquirer also should record, in the same period’s financial statements, the effect on earnings of changes in depreciation, amortization, or other income effects, if any, as a result of the change to the provisional amounts, calculated as if the accounting had been completed at the acquisition date. Second, the Update should be applied prospectively to adjustments to provisional amounts that are identified after December 15, 2015 and that are within the measurement period. Upon transition, an entity would be required to disclose the nature of, and reason for, the change in accounting principle. An entity would provide that disclosure in the first annual period of adoption and in the interim periods within the first annual period. The Company intends to adopt the Update during the first quarter of 2016. Adoption is not anticipated to have a material impact on the Company's financial statements.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation

Basis of Presentation

The accounting and reporting policies of the Company that materially affect its financial statements conform with U.S. Generally Accepted Accounting Principles ("GAAP"). The accompanying unaudited Condensed Consolidated Financial Statements of the Company have been prepared in conformity with the instructions for Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all the information and notes required by GAAP for complete financial statements and should be read in conjunction with the Company's Consolidated Financial Statements, and notes thereto, for the year ended December 31, 2014, included in the Company's Annual Report on Form 10-K filed with the SEC on February 27, 2015.

The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the amounts of assets and liabilities as of the date of the financial statements as well as income and expense during the period. Actual results could differ from those estimates. Operating results for the interim periods disclosed herein are not necessarily indicative of the results that may be expected for the full year or any future period.

Reclassification

Certain prior period amounts have been reclassified to conform to the current year's presentation. These reclassifications had an immaterial effect on net income, comprehensive income, total assets, total liabilities, total shareholders' equity, net cash provided by operating activities, net cash used for investing activities, and net cash provided by financing activities.

The Update clarifies that an in substance repossession or foreclosure occurs, and a creditor is considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan, upon either (i) the creditor obtaining legal title to the residential real estate property upon completion of a foreclosure or (ii) the borrower conveying all interest in the residential real estate property to the creditor to satisfy that loan through completion of a deed in lieu of foreclosure or through a similar agreement.

An entity may elect either a full retrospective or a modified retrospective application. ASU No. 2015-14 - Revenue from Contracts with Customers (Topic 606), defers the effective date of Update No. 2014-09 for all entities by one year. The Company will apply the guidance in Update 2014-09 to annual and interim periods beginning after December 15, 2017. The Company intends to adopt the Update during the first quarter of 2018. Adoption is not anticipated to have a material impact on the Company's financial statements.

ASU No. 2015-02 - Consolidation (Topic 810) - "Amendments to the Consolidation Analysis."

The Update simplifies the accounting for adjustments made to provisional amounts recognized in a business combination. First, the Update requires that the acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amount is determined. The acquirer also should record, in the same period’s financial statements, the effect on earnings of changes in depreciation, amortization, or other income effects, if any, as a result of the change to the provisional amounts, calculated as if the accounting had been completed at the acquisition date. Second, the Update should be applied prospectively to adjustments to provisional amounts that are identified after December 15, 2015 and that are within the measurement period. Upon transition, an entity would be required to disclose the nature of, and reason for, the change in accounting principle. An entity would provide that disclosure in the first annual period of adoption and in the interim periods within the first annual period. The Company intends to adopt the Update during the first quarter of 2016. Adoption is not anticipated to have a material impact on the Company's financial statements.

(1) Post-modification balances approximate pre-modification balances. The aggregate amount of charge-offs as a result of the restructurings was not significant.

The Company's loan and lease portfolio includes loans that have been restructured into an A-Note/B Note structure as a result of evaluating the cash flow of the borrowers to support repayment. Webster immediately charged off the balances of the B-Notes. The restructuring agreements specify a market interest rate equal to that which would be provided to a borrower with similar credit at the time of restructuring.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Financial Instruments

Derivative Financial Instruments

Risk Management Objective of Using Derivatives

Webster manages economic risks, including interest rate, liquidity, and credit risk by managing the amount, sources, and duration of its debt funding along with the use of interest rate derivative financial instruments. Webster enters into interest rate derivative financial instruments to manage exposure related to business activities that result in the receipt or payment of both future known and uncertain cash amounts determined by interest rates.

Webster’s primary objectives in using interest rate derivatives are to add stability to interest expense and to manage its exposure to interest rate movements. To accomplish these objectives, Webster uses interest rate swaps and interest rate caps as part of its interest rate risk management strategy. Interest rate swaps and caps designated as cash flow hedges are designed to manage the risk associated with a forecasted event or an uncertain variable-rate cash flow. Forward-settle interest rate swaps protect the Company against adverse fluctuations in interest rates by reducing its exposure to variability in cash flows relating to interest payments on forecasted debt issuances.

Interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. Interest rate caps designated as cash flow hedges involve the receipt of variable amounts from a counterparty if interest rates rise above the strike rate on the contract in exchange for payment of an up-front premium.

The effective portion of the change in the fair value of derivatives which are designated as and qualify as cash flow hedges is recorded as accumulated other comprehensive loss ("AOCL") and is subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. During the nine months ended September 30, 2015, such derivatives were used to hedge the variable cash flows associated with existing variable-rate debt and forecasted issuances of debt. The ineffective portion of the change in the fair value of the derivatives is recognized directly in earnings. During the three and nine months ended September 30, 2015 and 2014, the Company recorded no ineffectiveness and immaterial amounts of ineffectiveness in earnings, respectively, attributable to the difference in the effective date of the hedge and the effective date of the debt issuance.

At September 30, 2015, the Company has hedged its exposure to the variability in future cash flows for forecasted transactions over a maximum period of three months, excluding transactions related to the payment of variable interest on existing financial instruments.

Webster is also exposed to changes in the fair value of certain of its fixed-rate obligations due to changes in benchmark interest rates. Webster, on occasion, uses interest rate swaps to manage its exposure to changes in fair value on these obligations attributable to changes in the benchmark interest rates. Interest rate swaps designated as fair value hedges involve the receipt of fixed-rate amounts from a counterparty in exchange for Webster making variable-rate payments over the life of the agreements without the exchange of the underlying notional amount. For a qualifying derivative designated as a fair value hedge, the gain or loss on the derivative, as well as the gain or loss on the hedged item, is recognized in interest expense. Webster did not have interest rate derivative instruments designated as ‘fair value’ hedges at September 30, 2015 and December 31, 2014. There was no impact to interest expense during the three and nine months ended September 30, 2015. During the three and nine months ended September 30, 2014, there was no impact and $1.1 million reduction to interest expense, respectively, related to previous fair value hedges.

Webster has additional interest rate derivatives that do not qualify for hedge accounting and are, therefore, accounted for as free-standing derivatives with changes in fair value recorded in other non-interest income. Webster's derivatives not designated as hedges are not speculative and are used to manage the Company's exposure to interest rate movements and other identified risks but do not meet the strict hedge accounting requirements.

Additional derivative instruments include interest rate swap and cap contracts sold to commercial and other customers who wish to modify loan interest rate sensitivity. These contracts are offset with dealer counterparty transactions structured with matching terms. As a result, there is minimal impact on earnings, except for fee income earned in such transactions which is recorded in other non-interest income.

The Company enters into Risk Participation Agreements ("RPA") as financial guarantees of performance on interest rate swap derivatives. The purchased (asset) or sold (liability) guarantee allows the Company to participate-in (for a fee received) or participate-out (for a fee paid) the risk associated with certain derivative positions executed with the borrower by a lead bank. The RPA guarantee is recorded on the balance sheet at fair value, with changes in fair value recognized each period in other non-interest income.

Other derivatives include foreign currency forward contracts related to lending arrangements and a VISA share swap transaction, neither of which are designated for hedge accounting.

Amounts recorded in AOCL related to cash flow hedges

Amounts for the effective portion of changes in the fair value of derivatives are reclassified to interest expense as interest payments are made on Webster's variable-rate debt. Over the next twelve months, the Company estimates that $2.1 million will be reclassified from AOCL as an increase to interest expense.

Webster records gains and losses related to swap terminations to AOCL. These balances are subsequently amortized into interest expense over the respective terms of the hedged debt instruments. At September 30, 2015, the remaining unamortized loss on the termination of cash flow hedges is $31.3 million. Over the next twelve months, the Company estimates that $8.4 million will be reclassified from AOCL as an increase to interest expense.

Pre-tax amounts included in the Condensed Consolidated Statements of Income and Condensed Consolidated Statements of Comprehensive Income related to interest rate derivatives designated as hedges of cash flows were as follows:

Offsetting Derivatives

Webster has entered into transactions with counterparties that are subject to a master netting agreement. Hedge accounting positions are recorded on a gross basis in other assets for gain positions and in other liabilities for loss positions, while non-hedge accounting net positions are recorded in other assets for a net gain position and in other liabilities for a net loss position in the accompanying Condensed Consolidated Balance Sheets.

Counterparty Credit Risk

Derivative contracts involve the risk of dealing with both bank customers and institutional derivative counterparties and their ability to meet contractual terms. The Company has International Swap Derivative Association ("ISDA") Master agreements, including a Credit Support Annex ("CSA"), with all derivative counterparties. The ISDA Master agreements provide that on each payment date, all amounts otherwise owing the same currency under the same transaction are netted so that only a single amount is owed in that currency. The ISDA provides, if the parties so elect, for such netting of amounts in the same currency among all transactions identified as being subject to such election that have common payment dates and booking offices. Under the CSA, daily net exposure in excess of a negotiated threshold is secured by posted cash collateral. The Company has negotiated a zero threshold with the majority of its approved financial institution counterparties. In accordance with Webster policies, institutional counterparties must be analyzed and approved through the Company’s credit approval process.

The Company’s credit exposure on interest rate derivatives with non-dealer counterparties is limited to the net favorable value, including accrued interest, of all such instruments, reduced by the amount of collateral pledged by the counterparties. The Company's credit exposure related to derivatives with dealer counterparties is significantly mitigated with cash collateral equal to, or in excess of, the market value of the instrument, updated daily.

In accordance with counterparty credit agreements and derivative clearing rules, the Company had approximately $77.2 million in net margin collateral posted with financial counterparties at September 30, 2015, all of which were comprised of margin collateral posted to financial counterparties or DCO. Collateral levels for approved financial institution counterparties are monitored daily and adjusted as necessary. In the event of default, should the collateral not be returned, the exposure would be offset by terminating the transaction.

The Company regularly evaluates the credit risk of its counterparties, taking into account the likelihood of default, net exposures, and remaining contractual life, among other related factors. The Company's net current credit exposure relating to interest rate derivatives with Webster Bank customers was $78.2 million at September 30, 2015. In addition, the Company monitors potential future exposure, representing its best estimate of exposure to remaining contractual maturity. The potential future exposure relating to interest rate derivatives with Webster Bank customers totaled $18.7 million at September 30, 2015. The credit exposure is mitigated as transactions with customers are generally secured by the same collateral of the underlying transactions being hedged.

Mortgage Banking Derivatives

Forward sales of mortgage loans and MBS are utilized by Webster in its efforts to manage 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, interest rate lock commitments are generally extended to the borrowers. During the period from commitment date to closing date, Webster is subject to the risk that market rates of interest may change. If market rates rise, investors generally will pay less to purchase such loans causing a reduction in the anticipated gain on sale of the loans and possibly resulting in a loss. In an effort to mitigate such risk, forward delivery sales commitments are established under which Webster agrees to deliver whole mortgage loans to various investors or issue MBS. At September 30, 2015, outstanding rate locks totaled approximately $63.8 million, and the outstanding commitments to sell residential mortgage loans totaled approximately $82.2 million. Forward sales, which include mandatory forward commitments of approximately $79.0 million at September 30, 2015, establish the price to be received upon the sale of the related mortgage loan, thereby mitigating certain interest rate risk. There is, however, still certain execution risk specifically related to Webster’s ability to close and deliver to its investors the mortgage loans it has committed to sell. The interest rate locked loan commitments and forward sales commitments are recorded at fair value, with changes in fair value recorded as non-interest income in the accompanying Condensed Consolidated Statements of Income. The fair value of interest rate locked loan commitments and forward sales commitments resulted in a gain of $0.2 million at September 30, 2015 and a loss of $0.1 million at December 31, 2014, and were recorded as a component of other assets in the accompanying Condensed Consolidated Balance Sheets.

Credit Quality Indicators. 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 probability of borrower default and the loss given default. The credit risk grade system assigns a rating to each borrower and to the facility, which together form a Composite Credit Risk Profile (“CCRP”). The credit risk grade system categorizes borrowers by common financial profiles that measure the credit strength of borrowers and facilities by common structural characteristics. The CCRP has 10 grades, with each grade corresponding to a progressively greater risk of default. Grades 1 through 6 are considered pass ratings, and 7 through 10 are 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 the borrowers’ current financial positions and outlooks, risk profiles, and the related collateral and structural positions. Loan officers review updated financial information at least annually for all pass rated loans to assess the accuracy of the risk grade. All criticized loans undergo frequent review and enhanced monitoring of the underlying borrower.

A “Special Mention” (7) credit has the potential weakness that, if left uncorrected, may result in deterioration of the repayment prospects for the asset. “Substandard” (8) assets have a well-defined weakness that jeopardizes the full repayment of the debt. An asset rated “Doubtful” (9) 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 “Loss” (10) in accordance with regulatory guidelines are considered uncollectible and charged off.

The recorded investment in commercial loans, commercial real estate loans, and equipment financing leases segregated by risk rating exposure is as follows:

For residential and consumer loans, the Company considers factors such as updated FICO scores, employment status, home prices, loan to value, 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 both 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 Case-Shiller data indicates trends for Metropolitan Statistical Areas. The trend data is applied to the loan portfolios taking into account the age of the most recent valuation and geographic area.

Troubled Debt Restructurings ("TDRs")

(1) Post-modification balances approximate pre-modification balances. The aggregate amount of charge-offs as a result of the restructurings was not significant.

The Company's loan and lease portfolio includes loans that have been restructured into an A-Note/B Note structure as a result of evaluating the cash flow of the borrowers to support repayment. Webster immediately charged off the balances of the B-Notes. The restructuring agreements specify a market interest rate equal to that which would be provided to a borrower with similar credit at the time of restructuring.

The following table provides information on loans and leases modified as TDRs within the previous 12 months and for which there was a payment default during the periods presented:

Other-Than-Temporary Impairment ("OTTI")

The balance of OTTI, included in the amortized cost columns above, is related to certain CLO securities that are considered Covered Funds as defined by Section 619 of the Dodd-Frank Act, which continue to decline due to CLO deal refinancing and modifications.

To the extent that changes occur in interest rates, credit movements, and other factors that influence the fair value of its investment securities, the Company may be required to record impairment charges for OTTI in future periods.

The following table presents the changes in OTTI:

The following discussions by investment security type, summarize the basis for evaluating if investment securities within the Company’s available-for-sale and held-to-maturity portfolios were other-than-temporarily impaired at September 30, 2015. Unless otherwise noted for an investment security type, management does not intend to sell these investments and has determined, based upon available evidence, that it is more likely than not that the Company will not be required to sell these securities before the recovery of their amortized cost.

Available-for-Sale Impairment Analysis

Agency CMO. There were unrealized losses of $1.2 million on the Company’s investment in agency CMO at September 30, 2015 compared to $1.1 million at December 31, 2014. Unrealized losses were essentially flat at September 30, 2015 compared to December 31, 2014. The contractual cash flows for these investments are performing as expected, and there has been no change in the underlying credit quality. The Company does not consider these securities to be other-than-temporarily impaired at September 30, 2015.

Agency MBS. There were unrealized losses of $10.2 million on the Company’s investment in agency MBS at September 30, 2015 compared to $12.7 million at December 31, 2014. Unrealized losses decreased due to lower market rates which resulted in higher security prices at September 30, 2015 compared to December 31, 2014. These investments are issued by a government or a government-sponsored agency and, therefore, are backed by certain government guarantees, either direct or indirect. There has been no change in the credit quality, and the contractual cash flows are performing as expected. The Company does not consider these securities to be other-than-temporarily impaired at September 30, 2015.

Non Agency CMBS. There were unrealized losses of $1.2 million on the Company’s investment in non-agency CMBS at September 30, 2015 compared to $0.1 million at December 31, 2014. The composition of non-agency CMBS in the available-for-sale portfolio experienced increased market spreads which resulted in greater unrealized losses at September 30, 2015 compared to December 31, 2014. Internal and external metrics are considered when evaluating potential other-than temporary impairment. Internal stress tests are performed on individual bonds to monitor potential losses under stress scenarios. The contractual cash flows for these investments are performing as expected. The Company does not consider these securities to be other-than-temporarily impaired at September 30, 2015.

CLO. There were unrealized losses of $2.7 million on the Company's investments in CLO at September 30, 2015 compared to $1.0 million at December 31, 2014. Unrealized losses increased due to higher market spreads for the asset class which resulted in lower security prices at September 30, 2015 compared to December 31, 2014. The Company does not consider these securities to be other-than-temporarily impaired at September 30, 2015.

Single issuer trust preferred securities. There were unrealized losses of $4.3 million on the Company's investment in single issuer trust preferred securities at September 30, 2015 compared to $3.7 million at December 31, 2014. Unrealized losses increased due to higher market spreads for the asset class which resulted in lower security prices at September 30, 2015 compared to December 31, 2014. The single issuer portfolio consists of four investments issued by three large capitalization money center financial institutions, which continue to service the debt. The Company does not consider these securities to be other-than-temporarily impaired at September 30, 2015.

Held-to-Maturity Impairment Analysis

Agency CMO. There were unrealized losses of $0.6 million on the Company’s investment in agency CMO at September 30, 2015 compared to $0.7 million at December 31, 2014. Unrealized losses were essentially flat at September 30, 2015 compared to December 31, 2014. The contractual cash flows for these investments are performing as expected, and there has been no change in the underlying credit quality. The Company does not consider these securities to be other-than-temporarily impaired at September 30, 2015.

Agency MBS. There were unrealized losses of $10.8 million on the Company’s investment in agency MBS at September 30, 2015 compared to $11.3 million at December 31, 2014. Unrealized losses decreased due to lower market rates which resulted in higher security prices at September 30, 2015 compared to December 31, 2014. These investments are issued by a government or a government-sponsored agency and, therefore, are backed by certain government guarantees, either direct or indirect. There has been no change in the credit quality, and the contractual cash flows are performing as expected. The Company does not consider these securities to be other-than-temporarily impaired at September 30, 2015.

Municipal bonds and notes. There were unrealized losses of $1.6 million on the Company’s investment in municipal bonds and notes at September 30, 2015 compared to $0.1 million at December 31, 2014. Unrealized losses increased due to higher market spreads on recently purchased securities which resulted in lower security prices. The Company does not consider these securities to be other-than-temporarily impaired at September 30, 2015.

Non-agency CMBS. There were unrealized losses of $0.3 million on the Company’s investment in non-agency CMBS at September 30, 2015 compared to $1.0 million unrealized losses at December 31, 2014. Unrealized losses decreased due to lower market rates which resulted in higher security prices at September 30, 2015 compared to December 31, 2014. Internal and external metrics are considered when evaluating potential other-than temporary impairment. Internal stress tests are performed on individual bonds to monitor potential losses under stress scenarios. The contractual cash flows for these investments are performing as expected. The Company does not consider these securities to be other-than-temporarily impaired at September 30, 2015.

Total debt securities	$	2,995,914	$	3,012,331	$	3,951,208	$	4,023,546

For the maturity schedule above, mortgage-backed securities and collateralized loan obligations, which 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 maturity date presentation because borrowers have the right to prepay obligations with or without prepayment penalties. At September 30, 2015, the Company had a carrying value of $946.1 million in callable securities in its CMBS, CLO, and municipal bond portfolios. The Company considers these factors in the evaluation of its interest rate risk profile. These maturities do not reflect actual duration which is impacted by prepayments.

Securities with a carrying value totaling $2.9 billion at September 30, 2015 and December 31, 2014 were pledged to secure public funds, trust deposits, repurchase agreements, and for other purposes, as required or permitted by law. At September 30, 2015 and December 31, 2014, the Company had no investments in obligations of individual states, counties, or municipalities which exceeded 10% of consolidated shareholders’ equity.

Fair Value Disclosures [Abstract]

Fair Value Measurements

Fair Value Measurements

Fair value is 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. Fair value is best determined using quoted market prices. However, in many instances, quoted market prices are not available. In such instances, fair values are determined using appropriate valuation techniques. Various assumptions and observable inputs must be relied upon in applying these techniques. Accordingly, categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. As such, the fair value estimates may not be realized in an immediate transfer of the respective asset or liability.

Fair Value Hierarchy

The three levels within the fair value hierarchy are as follows:

• Level 1: Valuation is based upon unadjusted quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date.

• Level 2: Fair value is calculated using inputs other than quoted market prices that are directly or indirectly observable for the asset or liability. The valuation may rely on 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 (such as interest rates, volatilities, prepayment speeds, credit ratings, etc.), or inputs that are derived principally or corroborated by market data, by correlation, or other means.

• Level 3: Inputs for determining the fair value of the respective assets or liabilities are not observable. Level 3 valuations are reliant upon pricing models and techniques that require significant management judgment or estimation.

Assets and Liabilities Measured at Fair Value on a Recurring Basis

Available-for-Sale Investment Securities. When quoted prices are available in an active market, the Company classifies securities within Level 1 of the valuation hierarchy. Level 1 securities include equity securities in financial institutions and U.S. Treasury Bills.

If quoted market prices are not available, the Company classifies securities within Level 2 of the valuation hierarchy, and employs an independent pricing service that utilizes matrix pricing to calculate fair value. Such 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 respective terms and conditions for debt instruments. Management maintains procedures to monitor the pricing service's assumptions and establishes processes to challenge the pricing service's valuations that appear unusual or unexpected. Level 2 securities include agency CMO, agency MBS, agency CMBS, CMBS, CLO, single-issuer trust preferred securities, and corporate debt securities.

Derivative Instruments. 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 values are validated against valuations performed by independent third parties and are classified within Level 2 of the fair value hierarchy. In determining if any fair value adjustment related to credit risk is required, Webster evaluates the credit risk of its counterparties by considering factors such as the likelihood of default by the counterparties, its net exposures, the remaining contractual life, as well as the amount of collateral securing the position. Webster reviews its counterparty exposure on a regular basis, and, when necessary, appropriate business actions are taken to adjust the exposure. When determining fair value, Webster applies the portfolio exception with respect to measuring counterparty credit risk for all of its derivative transactions subject to a master netting arrangement. The change in value of derivative assets and liabilities attributable to credit risk was not significant during the reported periods.

Mortgage Banking Derivatives. Mortgage-backed securities are utilized by the Company in its efforts to manage 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 the period from commitment date to closing date, the Company is subject to the risk that market rates of interest may change. If market rates rise, investors generally will pay less to purchase such loans resulting in a reduction in the gain on sale of the loans or, possibly, a loss. In an effort to mitigate such risk, forward delivery sales commitments are established, under which the Company agrees to 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 and, therefore, classified within Level 2 of the fair value hierarchy.

Investments Held in Rabbi Trust. Investments held in a Rabbi Trust primarily include mutual funds that invest in equity and fixed income securities. Shares of mutual funds are valued based on net asset value, which represents quoted market prices for the underlying shares held in the mutual funds. Therefore, investments held in the Rabbi Trust are classified within Level 1 of the fair value hierarchy. Webster has elected to measure the investments held in the Rabbi Trust at fair value. The Company consolidates the invested assets of the trust along with the total deferred compensation obligations and includes them in other assets and other liabilities, respectively, in the accompanying Condensed Consolidated Balance Sheets. Earnings in the Rabbi Trust, including appreciation or depreciation, are reflected as other non-interest income, and changes in the corresponding liability are reflected as compensation and benefits in the accompanying Condensed Consolidated Statements of Income. The cost basis of the investments held in the Rabbi Trust is $3.9 million as of September 30, 2015.

Alternative Investments. The Company generally records alternative investments at cost, subject to impairment testing. The alternative investments that are carried at cost are considered to be measured at fair value on a non-recurring basis when there is impairment. There are certain funds in which the ownership percentage is greater than 3% and are, therefore, recorded at fair value on a recurring basis based upon the net asset value of the respective fund. Alternative investments are non-public entities that cannot be redeemed since the Company’s investment is distributed as the underlying investments are liquidated. As such, these investments are classified within Level 3 of the fair value hierarchy. The Company has $7.4 million in unfunded commitments remaining for its alternative investments as of September 30, 2015. See the Investment Securities Portfolio section of Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations for additional discussion of the Company's alternative investments.

Contingent Consideration. The contingent consideration arrangement entitles the Company to receive a rebate of the premium paid for account attrition that occurs during the eighteen-month period beginning on January 13, 2015, the closing date of the transaction. The valuation is reliant upon a pricing model and techniques that require significant management judgment or estimation. Therefore, the contingent consideration is classified within Level 3 of the fair value hierarchy. The key assumptions considered in the valuation model are a 2.5% annual growth rate, a 13.0% annual account attrition rate plus approximately 6.0% of shock attrition in 2015, a 16.5% discount rate, and a premium on deposits of 4.5%.

Contingent Liability. The liability valuation is based upon unobservable inputs. Therefore, the contingent liability is classified within Level 3 of the fair value hierarchy. The fair value of the contingency represents the estimated price to transfer the liability between market participants at the measurement date under current market conditions.

Summaries of the fair values for assets and liabilities measured at fair value on a recurring basis are as follows:

Assets Measured at Fair Value on a Non-Recurring Basis

Certain assets are measured at fair value on a non-recurring basis; that is, the assets are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances, for example, when there is evidence of impairment. The following is a description of valuation methodologies used for assets measured on a non-recurring basis.

Loans Held for Sale. Loans held for sale are accounted for at the lower of cost or market and are considered to be recognized at fair value when they are recorded at below cost. The fair value of residential mortgage loans held for sale is based on quoted market prices of similar loans sold in conjunction with securitization transactions. Accordingly, such loans are classified within Level 2 of the fair value hierarchy. On occasion, the loans held for sale portfolio includes commercial loans, which require adjustments for changes in loan characteristics. When observable data is unavailable, such loans are classified within Level 3.

Collateral Dependent Impaired Loans and Leases. Impaired loans and leases for which repayment is expected to be provided solely by the value of the underlying collateral are considered collateral dependent and are valued based on the estimated fair value of such collateral using customized discounting criteria. As such, collateral dependent impaired loans and leases are classified as Level 3 of the fair value hierarchy.

Other Real Estate Owned ("OREO") and Repossessed Assets. The total book value of OREO and repossessed assets was $5.4 million at September 30, 2015. OREO and repossessed assets are accounted for at the lower of cost or market and are considered to be recognized at fair value when they are recorded at below cost. The fair value of OREO is based on independent appraisals or internal valuation methods, less estimated selling costs. The valuation may consider available pricing guides, auction results, and price opinions. Certain assets require assumptions about factors that are not observable in an active market in the determination of fair value; as such, OREO and repossessed assets are classified within Level 3 of the fair value hierarchy.

Mortgage Servicing Assets. Mortgage servicing assets are accounted for at cost, subject to impairment testing. When the carrying cost exceeds fair value, a valuation allowance is established to reduce the carrying cost to fair 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; as such, the primary risk inherent in valuing mortgage servicing assets is the impact of fluctuating interest rates on the servicing revenue stream. Mortgage servicing assets are classified within Level 3 of the fair value hierarchy.

The table below presents the valuation methodology and unobservable inputs for Level 3 assets measured at fair value on a non-recurring basis at September 30, 2015:

(Dollars in thousands)
Asset	Fair Value		Valuation Methodology	Unobservable Inputs	Range of Inputs
Impaired loans and leases	$	22,603	Real Estate Appraisals	Discount for appraisal type	4% - 15%
				Discount for costs to sell	0% - 8%
Other real estate owned	$	1,820	Real Estate Appraisals	Discount for appraisal type	0% - 20%
				Discount for costs to sell	8%
Mortgage servicing assets	$	32,353	Discounted cash flow	Constant prepayment rate	7.4% - 32.4%
				Discount rates	1.4% - 3.4%

Fair Value of Financial Instruments

The Company is required to disclose the estimated fair value of financial instruments, both assets and liabilities, for which it is practicable to estimate fair value. The following is a description of valuation methodologies used for those assets and liabilities.

Cash, Due from Banks, and Interest-bearing Deposits. The carrying amount of cash, due from banks, and interest-bearing deposits is used to approximate fair value, given the short time frame to maturity and, as such, assets do not present unanticipated credit concerns. Cash, due from banks, and interest-bearing deposits are classified within Level 1 of the fair value hierarchy.

Held-to-Maturity Investment Securities. When quoted market prices are not available, the Company employs an independent pricing service to calculate fair value. Such 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 respective terms and conditions for debt instruments. Webster has procedures to monitor the pricing service's assumptions and establishes processes to challenge the pricing service's valuations that appear unusual or unexpected. Held-to-Maturity investments, which include agency CMO, agency MBS, agency CMBS, Municipal, and Private Label MBS securities, are classified within Level 2 of the fair value hierarchy.

Loans and Leases, net. The estimated fair value of loans and leases held for investment is calculated using a discounted cash flow method, using future prepayments and market interest rates inclusive of an illiquidity premium for comparable loans and leases. The associated cash flows are adjusted for credit and other potential losses. Fair value for impaired loans and leases is estimated using the net present value of the expected cash flows. Loans and leases are classified within Level 3 of the fair value hierarchy.

Deposit Liabilities. The fair value of demand deposits, savings accounts, and certain money market deposits is the amount payable on demand at the reporting date. The fair value of fixed-maturity certificates of deposit is estimated using the rates currently offered for deposits of similar remaining maturities. Deposit liabilities are classified within Level 2 of the fair value hierarchy.

Securities Sold Under Agreements to Repurchase and Other Borrowings. The carrying value is an estimate of fair value for those securities sold under agreements to repurchase and other borrowings that mature within 90 days. The fair values of all other borrowings are estimated using discounted cash flow analysis based on current market rates adjusted, as appropriate, for associated credit risks. 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 technique. Discount rates are matched with the time period of the expected cash flow and are adjusted, as appropriate, to reflect credit risk. FHLB advances and long-term debt are classified within Level 2 of the fair value hierarchy.

The estimated fair values of selected financial instruments are as follows:

	At September 30, 2015				At December 31, 2014
(In thousands)	Carrying Amount		Fair Value		Carrying Amount		Fair Value
Financial Assets:
Level 2
Held-to-maturity investment securities	$	3,951,208	$	4,023,546	$	3,872,955	$	3,948,706

Time deposits	2,061,740		2,084,841		2,271,587		2,288,760
Securities sold under agreements to repurchase and other borrowings	1,002,018		1,021,932		1,250,756		1,271,596
FHLB advances (2)	2,609,212		2,622,842		2,859,431		2,872,515
Long-term debt (3)	226,327		222,723		226,237		227,751

The following adjustments to the carrying amount are not included in the fair value:

(1) Mortgage servicing assets is net of reserves of $32 thousand at September 30, 2015 and $23 thousand at December 31, 2014.

(2) FHLB advances is net of unamortized premiums of $27 thousand at September 30, 2015 and $37 thousand at December 31, 2014.

(3) Long-term debt is net of unamortized discounts of $1.0 million at September 30, 2015 and $1.1 million at December 31, 2014.

Fair value estimates are made at a specific point in time, based on relevant market information and information about the financial instrument. These estimates do not reflect any premium or discount that could result from offering for sale at one time the entire holdings or any part of a particular financial instrument. Fair value estimates are based on judgments regarding future expected loss experience, current economic conditions, risk characteristics of various financial instruments, and other factors. These factors are subjective in nature and involve uncertainties and matters of significant judgment and, therefore, cannot be determined with precision. Changes in assumptions could significantly affect the estimates.

Transfers of Financial Assets and Mortgage Servicing Assets

Transfers of Financial Assets and Mortgage Servicing Assets

Transfers of Financial Assets

The Company sells financial assets in the normal course of business, primarily residential mortgage loans sold to government-sponsored enterprises through established programs and securities. The gain or loss on loans sold is included as mortgage banking activities in the accompanying Condensed Consolidated Statements of Income.

The Company may be required to repurchase a loan in the event of certain breaches of the representations and warranties, or in the event of default of the borrower within 90 days of sale, as provided for in the sale agreements. A reserve for loan repurchases provides for estimated losses pertaining to the potential repurchase of loans associated with the Company’s mortgage banking activities. The reserve reflects management’s monthly evaluation of the identity of counterparty, the vintage of the loans sold, the amount of open repurchase requests, specific loss estimates for each open request, the current level of loan losses in similar vintages held in the residential loan portfolio, and estimated recoveries on the underlying collateral. The reserve also reflects management’s expectation of losses from repurchase requests for which the Company has not yet been notified, as the performance of loans sold and the quality of the servicing provided by the acquirer also may impact the reserve. The provision recorded at the time of the loan sale is netted from the gain or loss recorded in mortgage banking activities, while any incremental provision, post loan sale, is recorded in other non-interest expense in the accompanying Condensed Consolidated Statements of Income.

The following table provides a summary of activity in the reserve for loan repurchases:

Mortgage Servicing Assets

The Company has retained servicing rights on loans totaling $2.5 billion at September 30, 2015 and $2.4 billion at December 31, 2014, resulting in mortgage servicing assets totaling $20.8 million at September 30, 2015 and $19.4 million at December 31, 2014, which are carried at the lower of cost or fair value and are included as a component of other assets in the accompanying Condensed Consolidated Balance Sheets. Changes in fair value are included as a component of other non-interest income in the accompanying Condensed Consolidated Statements of Income.

The following table presents the changes in fair value for those mortgage servicing assets:

	Nine months ended September 30,

Fair value at end of period	$	32,353		$	29,212

See Note 15: Fair Value Measurements for a further discussion on the fair value of mortgage servicing assets.

Loan servicing fees, net of mortgage servicing rights amortization, were $0.3 million and $1.1 million and $0.7 million and $1.4 million for the three andnine months ended September 30, 2015 and 2014, respectively, and are included as a component of loan related fees in the accompanying Condensed Consolidated Statements of Income.

Repurchase agreements are used as a source of borrowed funds and are collateralized by U.S. Government agency mortgage-backed securities, which are delivered to broker/dealers. Repurchase agreements with counterparties are limited to primary dealers in government securities and commercial/municipal customers through Webster’s Treasury Sales desk. Dealer counterparties have the right to pledge, transfer, or hypothecate purchased securities during the term of the transaction. The Company has a right of offset with respect to all repurchase agreement assets and liabilities. Total securities sold under agreements to repurchase represents the gross amount for these transactions, as only liabilities are outstanding for the periods presented.

Options to purchase 305 thousand shares for the three andnine months ended September 30, 2015 and 785 thousand shares for the three andnine months ended September 30, 2014 were excluded from the calculation of diluted earnings per share because the options’ exercise prices were greater than the average market price of Webster's common stock for the respective periods presented.

Restricted Stock

Non-participating restricted stock awards of 52 thousand shares and 93 thousand shares for the three andnine months ended September 30, 2015, respectively, and 157 thousand shares and 178 thousand shares for the three andnine months ended September 30, 2014, respectively, whose issuance is contingent upon the satisfaction of certain performance conditions, were deemed to be anti-dilutive and, therefore, were excluded from the calculation of diluted earnings per share for the respective periods presented.

Segment Reporting [Abstract]

Segment Reporting

Segment Reporting

Beginning in 2015, Webster’s operations are organized into four reportable segments that represent its core businesses – Commercial Banking, Community Banking, HSA Bank, and Private Banking. Community Banking includes the operating segments of Webster's Personal Banking and Business Banking. With the January 2015 acquisition of the health savings account business of JPMorgan Chase Bank, N.A., the reported revenue of the HSA Bank segment exceeds 10% of the combined revenue of all operating segments. As a result, the HSA Bank and Private Banking segments are disclosed separately. These segments reflect how executive management responsibilities are assigned by each of the core businesses, the products and services provided, and the type of customer served and reflect how discrete financial information is currently evaluated by the chief operating decision maker. The Company’s Treasury unit and consumer liquidating portfolio are included in the Corporate and Reconciling category along with the amounts required to reconcile profitability metrics to GAAP reported amounts. The 2014 segment results have been adjusted for comparability to the 2015 segment presentation.

Webster’s reportable segment results are intended to reflect each segment as if it were a stand-alone business. Webster uses an internal profitability reporting system to generate information by operating segment, which is based on a series of management estimates and allocations regarding funds transfer pricing, provision for loan and lease losses, non-interest expense, 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 reported results of any operating segment do not affect the consolidated financial position or results of operations of Webster as a whole. The full profitability measurement reports, which are prepared for each operating segment, reflect non-GAAP reporting methodologies. The differences between full profitability and GAAP results are reconciled in the Corporate and Reconciling segment.

The Company uses a matched maturity funding concept, called funds transfer pricing (“FTP”), to allocate interest income and interest expense to each business while also transferring the primary interest rate risk exposures to the Corporate and Reconciling category. The allocation process considers the specific interest rate risk and liquidity risk of financial instruments and other assets and liabilities in each line of business. The matched maturity funding concept 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. Loans are assigned an FTP rate for funds used and deposits are assigned an FTP rate for funds provided. This process is executed by the Company’s Financial Planning and Analysis division and is overseen by the Company’s Asset/Liability Committee.

Webster allocates the provision for loan and lease losses to each segment based on management’s estimate of the inherent loss content in each of the specific loan and lease portfolios. Provision expense for certain elements of risk that are not deemed specifically attributable to a reportable segment, such as the provision for the consumer liquidating portfolio, is shown as part of the Corporate and Reconciling segment.

Webster allocates a majority of non-interest expense to each reportable segment using a full-absorption costing process. Costs, including corporate overhead, are analyzed, pooled by process, and assigned to the appropriate reportable segment. Income tax expense is allocated to each reportable segment based on the consolidated effective income tax rate for the period shown.

The following tables present the results for Webster’s reportable segments and the Corporate and Reconciling category, which incorporates the allocation of the provision for loan and lease losses and income tax expense:

Acquisition

Acquisition

On January 13, 2015, Webster Bank completed its acquisition of the health savings account business of JPMorgan Chase Bank, N.A. As a result of the acquisition, the Company became the leading administrator of health savings accounts on a nationwide basis. The acquisition significantly augments a source of stable, low cost, long duration deposits.

The acquisition date fair value of the net consideration transferred consisted of the following:

(In thousands)	At January 13, 2015
Cash	$	50,485
Contingent consideration (1)	(5,000		)
Total net consideration transferred	$	45,485

(1) The contingent consideration arrangement entitles the Company to receive a rebate of the premium paid for account attrition that occurs during the eighteen-month period beginning on January 13, 2015, the closing date of the transaction.

The following table summarizes the estimated fair values of the assets acquired and liabilities assumed at the acquisition date:

(In thousands)	At January 13, 2015
Cash	$	1,446,898
Intangible assets	43,000
Total identifiable assets acquired	$	1,489,898
Deposits	$	1,446,899
Contingent liability	6,000
Total liabilities assumed	$	1,452,899
Net identifiable assets acquired	$	36,999
Goodwill	8,486
Net assets acquired	$	45,485

The fair value of the acquired identifiable intangible assets includes core deposit intangibles and customer relationships. The Company is in the process of completing its analysis of fair value of the assets acquired and liabilities assumed; thus, the measurements of identifiable intangible assets, goodwill, and contingencies are subject to change. Refer to Note 6: Goodwill and Other Intangible Assets for additional information relating to the initial amounts of goodwill and other intangible assets recognized.

The contingent liability represents an obligation that existed at the acquisition date. Accordingly, Webster assumed the liability as part of the transaction and has accounted for it at fair value.

Refer to Note 15: Fair Value Measurements for additional information on the contingent liability and contingent consideration recorded.

Commitments and Contingencies

Credit-Related Financial Instruments

The Company offers credit-related financial instruments, in the normal course of business to meet certain financing needs of its customers, that involve off-balance sheet risk. These transactions may include an unused commitment to extend credit, standby letter of credit, or commercial letter of credit. Such transactions 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 September 30, 2015		At December 31, 2014
Commitments to extend credit	$	4,938,617	$	4,376,733
Standby letter of credit	150,375		142,964
Commercial letter of credit	39,214		27,787
Total credit-related financial instruments with off-balance sheet risk	$	5,128,206	$	4,547,484

Commitments to Extend Credit. The Company makes commitments under various terms to lend funds to customers at a future point in time. These commitments include revolving credit arrangements, term loan commitments, and short-term borrowing agreements. Most of these loans have fixed expiration dates or other termination clauses where a fee may be required. Since commitments routinely expire without being funded, or after required availability of collateral occurs, the total commitment amount does not necessarily represent future liquidity requirements.

Standby Letter of Credit.A standby letter of credit commits the Company to make payments on behalf of customers if certain specified future events occur. The Company has recourse against the customer for any amount required to be paid to a third party under a standby letter of credit, which is often part of a larger credit agreement under which security is provided. Historically, a large percentage of standby letters of credit expire without being funded. The contractual amount of a standby letter of credit represents the maximum amount of potential future payments the Company could be required to make, and is the Company's maximum credit risk.

Commercial Letter of Credit.A commercial letter of credit is issued to facilitate either domestic or foreign trade arrangements for customers. As a general rule, drafts are committed to be drawn when the goods underlying the transaction are in transit. Similar to a standby letter of credit, a commercial letter of credit is often secured by an underlying security agreement including the assets or inventory they relate to.

These commitments subject the Company to potential exposure in excess of amounts recorded in the financial statements, and therefore, management maintains a specific reserve for unfunded credit commitments. This reserve is reported as a component of accrued expenses and other liabilities in the accompanying Condensed Consolidated Balance Sheets.

The following table provides a summary of activity in the reserve for unfunded credit commitments:

Litigation

Webster is involved in routine legal proceedings occurring in the ordinary course of business and is subject to loss contingencies related to such litigation and claims arising therefrom. Webster evaluates these contingencies based on information currently available, including advice of counsel and assessment of available insurance coverage. Webster establishes an accrual for litigation and claims when a loss contingency is considered probable and the related amount is reasonably estimable. This accrual is periodically reviewed and may be adjusted as circumstances change. Webster also estimates certain loss contingencies for possible litigation and claims, whether or not there is an accrued probable loss. Webster believes it has defenses to all the claims asserted against it in existing litigation matters and intends to defend itself in all matters.

Based upon its current knowledge, after consultation with counsel and after taking into consideration its current litigation accrual, Webster believes that at September 30, 2015 any reasonably possible losses, in addition to amounts accrued, are not material to Webster’s consolidated financial condition. However, in light of the uncertainties involved in such actions and proceedings, there is no assurance that the ultimate resolution of these matters will not significantly exceed the amounts currently accrued by Webster or that the Company’s litigation accrual will not need to be adjusted in future periods. Such an outcome could be material to the Company’s operating results in a particular period, depending on, among other factors, the size of the loss or liability imposed and the level of the Company’s income for that period.

Regulatory Capital Requirements [Abstract]

Regulatory Matters

Regulatory Matters

Webster is subject to regulatory capital requirements administered by the Federal Reserve, while Webster Bank is subject to regulatory capital requirements administered by the Office of the Comptroller of the Currency ("OCC"). Regulatory authorities can initiate certain mandatory actions if Webster or Webster Bank fail to meet minimum capital requirements, which could have a direct material effect on the Company’s financial statements. Capital adequacy guidelines and, additionally for banks, prompt corrective action regulations involve quantitative measures of assets, liabilities, and certain off-balance sheet items calculated under regulatory accounting practices. These quantitative measures, to ensure capital adequacy, require minimum amounts and ratios.

Basel III rules enhanced the comprehensive methodology for calculating risk-weighted assets which vary by asset class previously established under Basel I rules. Under Basel III, total risk-based capital is comprised of three categories: Common Equity Tier 1 capital ("CET1 capital"), additional Tier 1 capital, and Tier 2 capital. CET1 capital includes common shareholders' equity, less deductions for goodwill, other intangibles, and certain deferred tax losses. Webster's common shareholders' equity, for purposes of CET1, excludes accumulated other comprehensive components as permitted by the opt-out election taken by Webster upon adoption of BASEL III. Tier 1 capital is comprised of CET1 capital plus perpetual preferred stock, while Tier 2 capital includes qualifying subordinated debt and qualifying allowance for credit losses, that together equal total capital. Basel III became effective on January 1, 2015 for non-advanced approach banks as defined, and all prior period data is based on Basel I rules.

The following table provides information on the capital ratios for Webster Financial Corporation and Webster Bank, N.A.:

Dividend Restrictions

In the ordinary course of business, Webster is dependent upon dividends from Webster Bank to provide funds for its cash requirements, including payments of dividends to shareholders. Banking regulations may limit the amount of dividends that may be paid. Approval by regulatory authorities is required if the effect of dividends declared would cause the regulatory capital of Webster Bank to fall below specified minimum levels, or if dividends declared exceed the net income for that year combined with the undistributed net income for the preceding two years. In addition, the OCC has discretion to prohibit any otherwise permitted capital distribution on general safety and soundness grounds. Dividends paid by Webster Bank to Webster totaled $80 million for both the nine months ended September 30, 2015 and the nine months ended September 30,2014.
