Note 1: Summary of Significant Accounting Policies
Nature of Operations
Webster Financial Corporation is a bank holding company and financial holding company under the Bank Holding Company Act, incorporated under the laws of Delaware in 1986 and headquartered in Waterbury, Connecticut. At March 31, 2018, Webster Financial Corporation's principal asset is all of the outstanding capital stock of Webster Bank, National Association (Webster Bank).
Webster delivers financial services to individuals, families, and businesses primarily within its regional footprint from New York to Massachusetts. Webster provides business and consumer banking, mortgage lending, financial planning, trust, and investment services through banking offices, ATMs, mobile banking, and its internet website (www.websterbank.com or www.wbst.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, 2017, included in the Company's Annual Report on Form 10-K filed with the U.S. Securities and Exchange Commission (SEC) on March 1, 2018.
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 .
Accounting Standards Adopted During 2018
Effective January1, 2018, the following new Accounting Standards Updates (ASUs) were adopted by the Company:
ASU No. 2017-08, Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20) - Premium Amortization on Purchased Callable Debt Securities.
The Update shortens the amortization period for certain investments in callable debt securities purchased at a premium by requiring that the premium be amortized to the earliest call date. Prior to adoption, the Company amortized the premium as a yield adjustment over the contractual life of such debt securities. The Update accelerates the Company's recognition of premium amortization on certain debt securities held within the portfolio.
The Update is effective for the Company on January 1, 2019 and early adoption is permitted. The Company elected to early adopt the Update during the first quarter of 2018 on a modified retrospective basis. As a result, the Company recorded a $ 2.8 million cumulative-effect adjustment directly to retained earnings as of January 1, 2018.
ASU No. 2017-07, Compensation - Retirement Benefits (Topic 715) - Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost.
The Update requires the Company to retrospectively report service cost as a part of compensation expense and the other components of net periodic benefit cost separately from service cost in the Company's consolidated financial statements. The Company previously included all components of net periodic benefit cost as a component of compensation and benefits expense. Upon adoption, only service cost remains in compensation and benefits expense, while the interest cost on benefit obligations, expected return on plan assets, amortization of prior service cost, and recognized net loss components of the net periodic benefit cost are included in other expense, in the accompanying Condensed Consolidated Statements of Income.
The Company adopted the Update during the first quarter of 2018 on a retrospective basis. As a result, the Company reclassified, for prior periods, the components of it's net periodic benefit costs other than the service cost component from compensation and benefits to other expense in the accompanying Condensed Consolidated Statements of Income. The adoption of this guidance did not have a material impact on the Company's consolidated financial statements.
7
ASU No. 2016-15, Statement of Cash Flows (Topic 230) - Classification of Certain Cash Receipts and Cash Payments.
The Update addresses the following eight specific cash flow issues, with the objective of reducing the existing diversity in practice: debt prepayment or debt extinguishment costs; settlement of zero-coupon debt instruments or other debt instruments with coupon interest rates that are insignificant in relation to the effective interest rate of the borrowing; contingent consideration payments made after a business combination; proceeds from the settlement of insurance claims; proceeds from the settlement of corporate-owned life insurance policies, including bank-owned life insurance policies; distributions received from equity method investees; beneficial interests in securitization transactions; and separately identifiable cash flows and application of the predominance principle.
The Company adopted the Update during the first quarter of 2018 on a retrospective basis. The adoption of this guidance did not have a material impact on the Company's consolidated financial statements.
ASU No. 2016-01, Financial Instruments - Overall (Subtopic 825-10) - Recognition and Measurement of Financial Assets and Financial Liabilities, and ASU No. 2018-03, Technical Corrections and Improvements to Financial Instruments - Overall (Subtopic 825-10)
The Updates included targeted amendments in connection with the recognition, measurement, presentation, and disclosure of financial instruments. The main provisions require investments in equity securities to be measured at fair value through net income, unless they qualify for a practical expedient, and require fair value changes arising from changes in instrument-specific credit risk for financial liabilities that are measured under the fair value option to be recognized in other comprehensive income. The provisions also emphasized the existing requirement to use exit prices to measure fair value for disclosure purposes.
The Company adopted the Updates during the first quarter of 2018 primarily on a modified retrospective basis. As a result, the Company recorded a benefit of $ 1.4 million for a cumulative-effect adjustment directly to retained earnings, as of January 1, 2018, due to a change in valuation method, from cost less impairment, to net asset value using the practical expedient. Also, the measurement alternative has been elected for equity securities, existing as of January 1, 2018, without readily determinable fair values on a prospective basis.
ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606). Also, subsequent ASUs issued to clarify this Topic.
The Update, and subsequent related updates, establish a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most previous revenue recognition guidance, including industry-specific guidance. The Updates are intended to increase comparability across industries. The core principle of the revenue model is that a company will recognize revenue when it transfers control of goods or services to customers, at an amount that reflects the consideration to which it expects to be entitled in exchange for those goods or services.
The Company adopted the Updates during the first quarter of 2018 on a modified retrospective transition approach. The Company did not identify any material changes to the timing of revenue recognition. The Company is changing how it presents certain recurring revenue streams associated with wealth and investment services as other income, versus a contra expense; however, these changes did not have a significant impact on the Company's consolidated financial statements. The adoption of this guidance did not have a material impact on the Company's financial condition or results of operations, and there was no cumulative effect adjustment to opening retained earnings as no material changes were identified in the timing of revenue recognition, however, additional disclosure has been incorporated in Note 17: Revenue from Contracts with Customers.

Accounting Standards Issued But Not Yet Adopted
The following list identifies ASUs applicable to the Company that have been issued by the FASB but are not yet effective:
ASU No. 2017-12, Derivatives and Hedging (Topic 815) - Targeted Improvements to Accounting for Hedging Activities.
The purpose of the Update is to better align a company’s financial reporting for hedging activities with the economic objectives of those activities. The update requires a modified retrospective transition method in which a Company will recognize a cumulative effect of the change on the opening balance for each affected component of equity in the financial statements as of the date of adoption.
The Update is effective for the Company on January 1, 2019 and early adoption is permitted. The Company is in the process of assessing all potential impacts of the standard.
ASU No. 2017-04, Intangibles - Goodwill and Other (Topic 350) - Simplifying the Test for Goodwill Impairment.
The Update simplifies quantitative goodwill impairment testing by requiring entities to compare the fair value of a reporting unit with its carrying amount and recognize an impairment charge for any amount by which the carrying amount exceeds the reporting unit's fair value, to the extent that the loss recognized does not exceed the amount of goodwill allocated to that reporting unit.
This changes current guidance by eliminating the second step of the goodwill impairment analysis which involves calculating the implied fair value of goodwill determined in the same manner as the amount of goodwill recognized in a business combination upon acquisition. Entities will still have the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary.
The Update must be applied prospectively and is effective for the Company on January 1, 2020. Early adoption is permitted. The Company does not expect the new guidance to have a material impact on its financial statements.
ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326) - Measurement of Credit Losses on Financial Instruments.
Current GAAP requires an "incurred loss" methodology for recognizing credit losses. This approach delays recognition until it is probable a loss has been incurred. Both financial institutions and users of their financial statements expressed concern that current GAAP restricts the ability to record credit losses that are expected, but do not yet meet the "probable" threshold.
The main objective of this Update is to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. To achieve this objective, the amendments in this Update replace the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to determine credit loss estimates.
The Change from an "incurred loss" method to an "expected loss" method represents a fundamental shift from existing GAAP, and is likely to result in a material increase to the Company's accounting for credit losses on financial instruments. To prepare for implementation of the new standard the Company has established a project lead and has finalized a cross functional steering committee comprised of members from different disciplines including Credit, Finance and Treasury as well as specific working groups to focus on key components of the development process. In addition, through one of the working groups, the Company has begun to evaluate the effect that this Update will have on its financial statements and related disclosures. An implementation project plan has been created and is made up of targeted work streams focused on credit models, data management, accounting, and governance. These work streams are collectively assessing resources that may be required, use of existing and new models, data availability, and system solutions to facilitate implementation. The Update will be effective for the Company on January 1, 2020. While we are currently unable to reasonably estimate the impact of adopting the Update, we expect the impact of adoption will be significantly influenced by the composition, characteristics, and quality of our loan and securities portfolios as well as the economic conditions as of the adoption date.
ASU No. 2016-02, Leases (Topic 842).
The Update introduces a lessee model that requires substantially all leases to be recorded as assets and liabilities on the balance sheet and will require both quantitative and qualitative disclosures regarding key information about leasing arrangements.
The Company is in the process of reviewing its existing leases, including certain service contracts for embedded leases, to evaluate the impact of the standard on the consolidated financial statements, as well as the impact to regulatory reporting, such as capital and risk-weighted assets. The Company has engaged a third party consultant to assist with the implementation efforts.
The effect of the adoption will depend on the lease portfolio at the time of transition and the transition options ultimately available at the time of adoption. The guidance is effective beginning January 1, 2019 with an option to early adopt. The Company does not plan to early adopt the Update.

Note 2: Variable Interest Entities
The Company has an investment interest in the following entities that meet the definition of a variable interest entity (VIE).
Consolidated
Rabbi Trust. The Company established a Rabbi Trust to meet the obligations due under its Deferred Compensation Plan for Directors and Officers and to mitigate the expense volatility of the aforementioned plan. The funding of the Rabbi Trust and the discontinuation of the Deferred Compensation Plan for Directors and Officers occurred during 2012.
Investments held in the Rabbi Trust primarily consist of mutual funds that invest in equity and fixed income securities. The Company is considered the primary beneficiary of the Rabbi Trust as it has the power to direct the activities of the Rabbi Trust that significantly affect the VIE's economic performance and it has the obligation to absorb losses of the VIE that could potentially be significant to the VIE.
The Company consolidates the invested assets of the trust along with the total deferred compensation obligations and includes them in accrued interest receivable and other assets and accrued expenses 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. See Note 13: Fair Value Measurements for additional information.
Non-Consolidated
Securitized Investments. The Company, through normal investment activities, makes passive investments in securities issued by VIEs for which Webster is not the manager. The investment securities consist of Agency CMO, Agency MBS, Agency CMBS, CLO and single issuer-trust preferred. The Company has not provided financial or other support with respect to these investment securities other than its original investment. For these investment securities, the Company determined it is not the primary beneficiary due to the relative size of its investment in comparison to the principal amount of the structured securities issued by the VIEs, the level of credit subordination which reduces the Company’s obligation to absorb losses or right to receive benefits and its inability to direct the activities that most significantly impact the economic performance of the VIEs. The Company’s maximum exposure to loss is limited to the amount of its investment in the VIEs. See Note 3: Investment Securities for additional information.
Tax Credit - Finance Investments. The Company makes equity investments in entities that finance affordable housing and other community development projects and provide a return primarily through the realization of tax benefits. In most instances the investments require the funding of capital commitments in the future. While the Company's investment in an entity may exceed 50% of its outstanding equity interests, the entity is not consolidated as Webster is not involved in its management. For these investments, the Company determined it is not the primary beneficiary due to its inability to direct the activities that most significantly impact the economic performance of the VIEs. The Company applies the proportional amortization method to account for its investments in qualified affordable housing projects.
At March 31, 2018 and December 31, 2017, the aggregate carrying value of the Company's tax credit-finance investments were $ 32.5 million and $ 33.5 million, respectively. At March 31, 2018 and December 31, 2017, unfunded commitments have been recognized, totaling $ 16.2 million and $ 17.3 million, respectively, and are included in accrued expenses and other liabilities in the accompanying Condensed Consolidated Balance Sheets.
Webster Statutory Trust. The Company owns all the outstanding common stock of Webster Statutory Trust, a financial vehicle that has issued, and in the future may issue, trust preferred securities. The trust is a VIE in which the Company is not the primary beneficiary. The trust's only assets are junior subordinated debentures issued by the Company, which were acquired by the trust using the proceeds from the issuance of the trust preferred securities and common stock. The junior subordinated debentures are included in long-term debt in the accompanying Condensed Consolidated Balance Sheets, and the related interest expense is reported as interest expense on long-term debt in the accompanying Condensed Consolidated Statements of Income.
Other Investments. The Company invests in various alternative investments in which it holds a variable interest. Alternative investments are non-public entities which cannot be redeemed since the Company’s investment is distributed as the underlying equity is liquidated. For these investments, the Company has determined it is not the primary beneficiary due to its inability to direct the activities that most significantly impact the economic performance of the VIEs.
At March 31, 2018 and December 31, 2017, the aggregate carrying value of the Company's other investments in VIEs were $ 16.3 million and $ 13.8 million, respectively, and the total exposure of the Company's other investments in VIEs, including unfunded commitments, were $ 25.3 million and $ 22.9 million, respectively.
The Company's equity interests in Tax Credit-Finance Investments, Webster Statutory Trust, and Other Investments are included in accrued interest receivable and other assets in the accompanying Condensed Consolidated Balance Sheets. For a description of the Company's accounting policy regarding the consolidation of VIEs, refer to Note 1 to the Consolidated Financial Statements included in its Form 10-K, for the year ended December 31, 2017 .

Impairment Analysis
The following impairment analysis summarizes the basis for evaluating if investment securities within the Company’s available-for-sale and held-to-maturity portfolios have been impacted by OTTI since December 31, 2017. Unless otherwise noted for an investment security type, management does not intend to sell these investment securities and has determined, based upon available evidence, that it is more likely than not that the Company will not be required to sell these investment securities before the recovery of their amortized cost. As such, based on the following impairment analysis, the Company does not consider any of these investment securities, in unrealized loss positions, to be other-than-temporarily impaired at March 31, 2018.

For the maturity schedule above, mortgage-backed securities and CLO, 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 as borrowers have the right to prepay obligations with or without prepayment penalties.
At March 31, 2018, the Company had a carrying value of $ 1.2 billion in callable investment securities in its CMBS, CLO, and municipal bond portfolios. The Company considers prepayment risk in the evaluation of its interest rate risk profile. These maturities may not reflect actual durations, which may be impacted by prepayments.
Investment securities with a carrying value totaling $ 2.6 billion at March 31, 2018 and $ 2.4 billion at December 31, 2017 were pledged to secure public funds, trust deposits, repurchase agreements, and for other purposes, as required or permitted by law.

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

For residential and consumer loans, the primary credit quality indicator that the Company considers is past due status. Other factors, such as, updated Fair Isaac Corporation (FICO) scores, employment status, collateral, geography, loans discharged in bankruptcy, and the status of first lien position loans on second lien position loans as credit quality indicators may also be evaluated. On an ongoing basis for portfolio monitoring purposes, the Company estimates the current value of property secured as collateral for home equity and residential first mortgage lending products. The estimate is based on home price indices compiled by the S&P/Case-Shiller Home Price Indices. The real estate price data is applied to the loan portfolios taking into account the age of the most recent valuation and geographic area.

Note 5: 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 securitizations. The gain or loss on residential mortgage loans sold and the related origination fee income, and the fair value adjustment to loans held-for-sale are 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 evaluation of the identity of the 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 10: Regulatory Matters
Capital Requirements
Webster Financial Corporation is subject to regulatory capital requirements administered by the Federal Reserve System, 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 Financial Corporation or Webster Bank fail to meet minimum capital requirements, which could have a direct material effect on the Company’s financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, both Webster Financial Corporation and Webster Bank must meet specific capital guidelines that involve quantitative measures of assets, liabilities, and certain off-balance sheet items calculated under regulatory accounting practices. These quantitative measures require minimum amounts and ratios to ensure capital adequacy.
Basel III total risk-based capital is comprised of three categories: 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 adjustments. Common shareholders' equity, for purposes of CET1 capital, excludes AOCL 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.
The following table provides information on the capital ratios for Webster Financial Corporation and Webster Bank:
| At March 31, 2018 |

Dividend Restrictions
Webster Financial Corporation 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 Financial Corporation totaled $ 100 million during the three months ended March 31, 2018 compared to $ 10 million during the three months ended March 31, 2017.
Cash Restrictions
Webster Bank is required by Federal Reserve System regulations to hold cash reserve balances on hand or with the Federal Reserve Bank. Pursuant to this requirement, Webster Bank held $ 79.8 million and $ 82.3 million at March 31, 2018 and December 31, 2017 , respectively.

Note 12: Derivative Financial Instruments
Risk Management Objective of Using Derivatives
Webster manages economic risks, such as interest rate, liquidity, and credit risks by managing the amount, sources, and duration of its debt funding in conjunction with the use of interest rate derivative financial instruments. Webster enters into interest rate derivatives to mitigate the exposure related to business activities that result in the future receipt or payment of, both known and uncertain, cash amounts that are impacted by interest rates. The primary objective for using interest rate derivatives is to add stability to interest expense by managing exposure to interest rate movements. To accomplish this objective, Webster uses interest rate swaps and interest rate caps as part of its interest rate risk management strategy.
Interest rate swaps and interest rate 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.
Cash flow hedges are used to regulate the variable cash flows associated with existing variable-rate debt and forecasted issuances of debt. Derivative instruments designated as cash flow hedges are recorded on the balance sheet at fair value. The effective portion of the change in fair value of the derivatives which are designated as cash flow hedges, and that qualify for hedge accounting, is recorded to AOCL and is reclassified into earnings in the subsequent periods that the hedged forecasted transaction affects earnings. The ineffective portion of the change in fair value of these derivatives, attributable to the difference in the effective date of the hedge and the effective date of the debt issuance, is recognized directly in earnings. During the periods presented, there was no ineffectiveness to be recognized in earnings.
Certain fixed-rate obligations can be exposed to a change in fair value attributable to changes in benchmark interest rates. On occasion, interest rate swaps will be used to manage this exposure. An interest rate swap which involves the receipt of fixed-rate amounts from a counterparty in exchange for Webster making variable-rate payments over the life of the agreement, without the exchange of the underlying notional amount, is designated as a fair value hedge. 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. During the periods presented, Webster did not have any interest rate derivative financial instruments designated as fair value hedges and as a result, there was no impact to interest expense.
Additionally, in order to address certain other risk management matters, the Company also utilizes derivative instruments that do not qualify for hedge accounting. These derivative instruments, which are recorded on the balance sheet at fair value, with changes in fair value recognized each period as other non-interest income in the accompanying Condensed Consolidated Statements of Income, are described in the following paragraphs.
Interest rate swap and cap contracts are 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.
Risk participation agreements (RPAs) are entered into as financial guarantees of performance on interest rate swap derivatives. The purchased (asset) or sold (liability) guarantee allows the Company to participate-in (fee received) or participate-out (fee paid) the risk associated with certain derivative positions executed with the borrower by the lead bank in a loan syndication.
Other derivatives include foreign currency forward contracts related to lending arrangements, a VISA equity swap transaction, and mortgage banking derivatives such as mortgage-backed securities related to residential loan commitments and loans held for sale. Mortgage banking derivatives 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, or 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 mortgage-backed securities. Mandatory forward commitments 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.

Amounts for the effective portion of changes in the fair value of derivatives qualifying for hedge accounting treatment 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 $ 0.2 million will be reclassified from AOCL as an increase to interest expense.
Webster records gains and losses related to hedge terminations to AOCL. These balances are subsequently amortized into interest expense over the respective terms of the hedged debt instruments. At March 31, 2018, the remaining unamortized loss on the termination of cash flow hedges is $ 13.3 million. Over the next twelve months, the Company estimates that $ 5.6 million will be reclassified from AOCL as an increase to interest expense.
Additional information about cash flow hedge activity impacting AOCL, and the related amounts reclassified to interest expense is provided in Note 9: Accumulated Other Comprehensive Loss, Net of Tax. Information about the valuation methods used to measure the fair value of derivatives is provided in Note 13: Fair Value Measurements.

Counterparty Credit Risk
Use of derivative contracts may expose the bank to counterparty credit risk. The Company has International Swaps Derivative Association (ISDA) master agreements, including a Credit Support Annex, 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 Credit Support Annex, 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 $ 50.1 million in net margin collateral received from financial counterparties at March 31, 2018, comprised of $ 33.5 million in initial margin and $ 83.6 million in variation margin collateral received from financial counterparties or the derivative clearing organization. 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 $ 9.9 million at March 31, 2018. 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 $ 29.6 million at March 31, 2018 . Credit risk exposure is mitigated as transactions with customers are generally secured by the same collateral of the underlying transactions being hedged.

Note 13: 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 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.
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 significant 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. |

Available-for-Sale Investment Securities. When quoted prices are available in an active market, the Company classifies investment securities within Level 1 of the valuation hierarchy. U.S. Treasury Bills are classified within Level 1 of the fair value hierarchy.
When quoted market prices are not available, the Company employs an independent pricing service that utilizes matrix pricing to calculate fair value. 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 results and establishes processes to challenge their valuations, or methodology, that appear unusual or unexpected. Available-for-Sale investment securities which include Agency CMO, Agency MBS, Agency CMBS, CMBS, CLO, single issuer-trust preferred, and corporate debt, are classified within Level 2 of the fair value hierarchy.
Derivative Instruments. Foreign exchange contracts are valued based on unadjusted quoted prices in active markets and classified within Level 1 of the fair value hierarchy.
All other derivative instruments are valued using third-party valuation software, which considers the present value of cash flows discounted using observable forward rate assumptions. The resulting fair 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 mitigate 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 Chicago Mercantile Exchange rulebooks legally characterize variation margin payments for over-the-counter derivatives to clear as settlements rather than collateral, which impacts one of Webster's counterparty relationships, resulting in the fair value of the instrument including cash collateral to be represented as a single unit of account.
The change in value of derivative assets and liabilities attributable to credit risk was not significant during the reported periods.

Mortgage Banking Derivatives. Forward sales of mortgage loans and 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.
Originated Loans Held For Sale. Residential mortgage loans typically are classified as held for sale upon origination based on management's intent to sell such loans. The Company has elected to measure originated loans held for sale under the fair value option of Accounting Standards Codification (ASC) Topic 825 "Financial Instruments," on a loan-by-loan basis. 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, these loans are classified within Level 2 of the fair value hierarchy.
The following table presents the fair value, unpaid principal balance, and accrual status of assets accounted for under the fair value option:
| March 31, 2018 | December 31, 2017 |
| (In thousands) | Fair Value | Unpaid Principal Balance | Difference | Fair Value | Unpaid Principal Balance | Difference |
| Originated loans held for sale | $ | 19,727 | $ | 19,663 | $ | 64 | $ | 20,888 | $ | 20,346 | $ | 542 |

Electing to measure originated loans held for sale at fair value reduces certain timing differences and better matches changes in the value of these assets with changes in the value of the derivatives used as an economic hedge on these assets. Assets accounted for under the fair value option are initially measured at fair value. Gains and losses from initial measurement and subsequent changes in fair value are recognized in earnings. For the three months ended March 31, 2018 net loss from fair value changes was $ 0.3 million and for the three months ended March 31, 2017 net gains from fair value changes was $ 1.2 million . The Company does not account for liabilities under the fair value option .
Investments Held in Rabbi Trust. Investments held in the 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 cost basis of the investments held in the Rabbi Trust is $ 2.1 million at March 31, 2018.
Alternative Investments Net Asset Value (NAV). Alternative investments that are fair valued on a recurring basis are based upon the NAV of the respective fund. Therefore, alternative investments (NAV) are not classified within the fair value hierarchy. At March 31, 2018, alternative investments (NAV) had a remaining unfunded commitment of $ 0.3 million. The Company's alternative investments (NAV) consists of investments in non-public entities that generally cannot be redeemed since the Company’s investments are distributed as the underlying equity is liquidated.

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.
Alternative Investments. Alternative investments are investments in non-public entities that generally cannot be redeemed since the investment is distributed as the underlying equity is liquidated. The measurement alternative has been elected for alternative investments without readily determinable fair values that do not qualify for the NAV practical expedient. The measurement alternative requires investments to be accounted for at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. Accordingly, these alternative investments are classified within Level 3 of the fair value hierarchy. The carrying amount of these alternative investments was $ 7.9 million at March 31, 2018. No reduction for impairments, or increase or decrease due to observable price changes, was identified during the three months ended March 31, 2018.
Transferred Loans Held For Sale. Certain loans are transferred to loans held for sale once a decision has been made to sell such loans. These loans 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. This activity is primarily commercial loans with observable inputs and is classified within Level 2. On the occasion should these loans include adjustments for changes in loan characteristics using unobservable inputs, the loans would be 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 and Repossessed Assets. The total book value of other real estate owned (OREO) and repossessed assets was $ 5.8 million at March 31, 2018. 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.
The table below presents the valuation methodology and unobservable inputs for Level 3 assets measured at fair value on a non-recurring basis as of March 31, 2018:
| (Dollars in thousands) |
| Asset | Fair Value | Valuation Methodology | Unobservable Inputs | Range of Inputs |
| Collateral dependent impaired loans and leases | $ | 13,424 | Real Estate Appraisals | Discount for appraisal type | 0 % | - | 15 % |
| Discount for costs to sell | 0 % | - | 8 % |
| OREO | $ | 858 | Real Estate Appraisals | Discount for costs to sell | 8 % |

Fair Value of Financial Instruments and Servicing Assets
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, these 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 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 results and establishes processes to challenge their valuations, or methodology, that appear unusual or unexpected. Held-to-Maturity investment securities, which include Agency CMO, Agency MBS, Agency CMBS, CMBS, municipal bonds and notes, 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.
33
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. Deposit liabilities are classified within Level 2 of the fair value hierarchy.
Time Deposits. The fair value of a fixed-maturity certificate of deposit is estimated using the rates currently offered for deposits of similar remaining maturities. Time deposits are classified within Level 2 of the fair value hierarchy.
Securities Sold Under Agreements to Repurchase and Other Borrowings. The carrying value is an estimate of fair value for those securities sold under agreements to repurchase and other borrowings that mature within 90 days. Fair value of all other borrowings is 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.
Mortgage Servicing Assets. Mortgage servicing assets are accounted for at cost, subject to impairment testing. Mortgage servicing assets are considered to be recognized at fair value when they are recorded at below cost. Changes in fair value are included as a component of other non-interest income in the accompanying Condensed Consolidated Statements of Income. 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 estimated fair values of selected financial instruments and servicing assets are as follows:
| At March 31, 2018 | At December 31, 2017 |
| (In thousands) | CarryingAmount | FairValue | CarryingAmount | FairValue |
| Assets: |

The components of net periodic benefit cost, other than the service cost component, are included as a component of other expense reflected in non-interest expense in the accompanying Condensed Consolidated Statements of Income.
Note 15: Share-Based Plans
Stock compensation plans
Webster maintains stock compensation 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.
Stock compensation expense of $ 3.3 million for both the three months ended March 31, 2018 and 2017, related to restricted stock awards, was recognized in the accompanying Condensed Consolidated Statements of Income.
At March 31, 2018 there was $ 21.0 million of unrecognized stock compensation expense for restricted stock expected to be recognized over a weighted-average period of 2.3 years.
The following table provides a summary of the stock compensation plans activity for the three months ended March 31, 2018:

| (1) | V ested for purposes of recording compensation expense. |

Time-based restricted stock. Time-based restricted stock awards vest over the applicable service period ranging from 1 to 5 years. The number of time-based awards that may be granted to an eligible individual in a calendar year is limited 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 3 year performance period. The awards vest with a share quantity dependent on that performance, in a range from 0 to 150 %. The performance criteria for 50 % of the shares granted in 2018 is based upon Webster's ranking for total shareholder return versus Webster's compensation peer group companies and the remaining 50 % is based upon Webster's average of return on equity during the 3 year vesting period. The compensation peer group companies are utilized because they represent the financial institutions that best compare with
35
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 Financial Corporation's stock on the date of grant. Each option grants the holder the right to acquire a share of Webster Financial Corporation common stock over a contractual life of up to 10 years. All awarded options have vested. There were 627,635 non-qualified stock options and 33,888 incentive stock options outstanding at March 31, 2018 .
Note 16: Segment Reporting
Webster’s operations are organized into three reportable segments that represent its primary businesses - Commercial Banking, HSA Bank, and Community Banking. These three segments reflect how executive management responsibilities are assigned, the primary businesses, the products and services provided, the type of customer served, and how discrete financial information is currently evaluated. The Corporate Treasury unit of the Company, along with the amounts required to reconcile profitability metrics to amounts reported in accordance with GAAP, are included in the Corporate and Reconciling category.
Description of Segment Reporting Methodology
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 category.
Webster allocates interest income and interest expense to each business, while also transferring the primary interest rate risk exposures to the Corporate and Reconciling category, using a matched maturity funding concept called Funds Transfer Pricing (FTP). 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 (ALCO).
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 category.
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.
Beginning in 2018, income tax expense is estimated for each reportable segment individually. The 2017 income tax expense was estimated for all segments using the consolidated effective tax rate. This change in the estimate of income tax expense reflects an estimate of full profitability for each of the individual business segments based on the nature of their operations.
The following table presents total assets for Webster's reportable segments and the Corporate and Reconciling category:

The Company adopted ASU 2014-09, Revenue from Contracts with Customers (Topic 606) and subsequent clarifying ASUs effective January 1, 2018. The Updates are applicable to the Company's deposit service fees, wealth and investment services, and an insignificant component of other income included within non-interest income in the accompanying Condensed Consolidated Statements of Income.
The Company's revenue associated with net interest income, and certain non-interest income line items (loan and lease related fees, mortgage banking activities, increase in cash surrender value of life insurance policies, gain on sale of investment securities, net, impairment loss on securities recognized in earnings, and a majority of other income), are not within the scope of Topic 606. As a result, a substantial amount of the Company's revenue was not affected.
Under the updated guidance, for in-scope revenue streams, the Company identifies the performance obligations included in the contracts with customers, determines the transaction price, allocates the transaction price to the performance, as applicable, and recognizes revenue when performance obligations are satisfied. The Company's existing recognition practices are largely consistent with the updated guidance.

Deposit service fees
Deposit service fees predominately consist of fees earned from deposit accounts and interchange revenue. Fees earned from deposit accounts relate to event-driven services and periodic account maintenance activities. Webster's obligations for event-driven services are satisfied at the time the service is delivered, while the obligations for maintenance services is satisfied monthly. Interchange fees are assessed as the performance obligation is satisfied, which is at the point in time the card transaction is authorized.
Wealth and investment services
Wealth and investment services consists of fees earned from investment and securities-related services, trust and other related services. Obligations for wealth and investment services are generally satisfied over time through a time-based measurement of progress, but certain obligations may be satisfied at points in time for activities that are transactional in nature.

Note 18: 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 March 31, 2018 | At December 31, 2017 |
| Commitments to extend credit | $ | 5,648,126 | $ | 5,567,687 |
| Standby letter of credit | 167,899 | 195,902 |
| Commercial letter of credit | 44,535 | 43,200 |
| Total credit-related financial instruments with off-balance sheet risk | $ | 5,860,560 | $ | 5,806,789 |

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 to which they relate.
These commitments subject the Company to potential exposure in excess of the 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 March 31, |
| (In thousands) | 2018 | 2017 |
| Beginning balance | $ | 2,362 | $ | 2,287 |
| (Benefit) provision charged to expense | ( 68 | ) | 368 |
| Ending balance | $ | 2,294 | $ | 2,655 |

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 March 31, 2018 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.

Note 19: Subsequent Events
The Company has evaluated events from the date of the Condensed Consolidated Financial Statements and accompanying Notes thereto, March 31, 2018, through the issuance of this Quarterly Report on Form 10-Q and determined that no significant events were identified requiring recognition or disclosure.

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, 2017, included in the Company's Annual Report on Form 10-K, filed with the SEC on March 1, 2018, and in conjunction with the Condensed Consolidated Financial Statements and Notes thereto included in Item 1 of this report. Operating results for the three months ended March 31, 2018 are not necessarily indicative of the results for the full year ending December 31, 2018, or any future period.
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 2017 Annual Report on Form 10-K. Modifications to significant accounting policies made during the year are described 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 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 the Company's most critical accounting policies as:
| • | allowance for loan and lease losses; |

| • | fair value measurements for valuation of investments; |

| • | evaluation for impairment of goodwill; and |

| • | assessing the realizability of deferred tax assets and the measurement of uncertain tax positions. |

These particular significant accounting policies are considered most critical 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. The 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 2017 Form 10-K and Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations, of this report.

Providing the non-GAAP financial measures identified in the preceding table provides investors with information useful in understanding the Company's financial performance, performance trends and financial position. These measures are used by management for internal planning and forecasting purposes, as well as by securities analysts, investors and other interested parties to compare peer company operating performance. Management believes that the presentation, together with the accompanying reconciliations provides a complete understanding of the factors and trends affecting the Company's business and allows investors to view its performance in a similar manner. These non-GAAP financial measures should not be considered a substitute for GAAP basis measures and results. Because non-GAAP financial measures are not standardized, it may not be possible to compare these measures with other companies that present measures having the same or similar names.
The following tables reconcile the non-GAAP financial measures with financial measures defined by GAAP:

Financial Performance
For the three months ended March 31, 2018, net income before tax of $100.3 million increased $18.9 million, or 23.2%, from the three months ended March 31, 2017 due to improved performance across all businesses, driven by increased net interest margin and stable credit quality.
The impact of the items outlined above, coupled with the effect from a lower tax rate resulting in income tax expense of $20.1 million and $22.0 million for the three months ended March 31, 2018 and 2017, respectively, resulted in net income of $80.2 million and diluted earnings per share of $0.85 for the three months ended March 31, 2018 compared to net income of $59.5 million and diluted earnings per share of $0.62 for the three months ended March 31, 2017.

43
Net interest income and net interest margin are impacted by the level of interest rates, mix of assets earning and liabilities paying those interest rates, and the volume of interest-earning assets and interest-bearing liabilities. These conditions are influenced by changes in economic conditions that impact interest rate policy, competitive conditions that impact loan and deposit pricing strategies, as well as the extent of interest lost to non-performing assets.
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 75.7% of total revenue for the three months ended March 31, 2018. Net interest margin is the ratio of tax-equivalent net interest income to average earning assets for the period.
Webster manages the risk of changes in interest rates on net interest income and net interest margin through ALCO and through related interest rate risk monitoring and management policies. ALCO meets at least monthly to make decisions on the investment and funding portfolios based on the economic outlook, its interest rate expectations, the portfolio risk position, and other factors.
Four main tools are used for managing interest rate risk:
| • | the size, duration, and credit risk of the investment portfolio; |

| • | the size and duration of the wholesale funding portfolio; |

| • | off-balance sheet interest rate contracts; and |

| • | the pricing and structure of loans and deposits. |

The Federal Open Market Committee increased the federal funds rate target range from 1.25-1.50% on December 31, 2017 to 1.50-1.75% effective March 22, 2018. See the "Asset/Liability Management and Market Risk" section for further discussion of Webster's interest rate risk position
Net Interest Income
Net interest income totaled $214.2 million for the three months ended March 31, 2018 compared to $192.7 million for the three months ended March 31, 2017, an increase of $21.5 million.
Net interest margin increased 22 basis point to 3.44% for the three months ended March 31, 2018 from 3.22% for the three months ended March 31, 2017. On a fully tax-equivalent basis, net interest income increased $19.7 million when compared to the same period in 2017. The increase for the three months ended March 31, 2018 was primarily the result of strong loan growth at increased yields, slightly offset with a flat securities portfolio experiencing a decline in reinvestment spreads on those assets.
Changes in Net Interest Income
The following table presents the components of the change in net interest income attributable to changes in rate and volume, and reflects net interest income on a fully tax-equivalent basis:

Average loans and leases for the three months ended March 31, 2018 increased $0.7 billion compared to the average for the three months ended March 31, 2017. The loan and lease portfolio comprised 70.7% of the average interest-earning assets at March 31, 2018 compared to 69.8% of the average interest-earning assets at March 31, 2017. The loan and lease portfolio yield increased 40 basis points to 4.37% for the three months ended March 31, 2018 compared to 3.97% for the three months ended March 31, 2017. The increase in the yield on the average loan and lease portfolio is due to variable rate loans resetting higher. Additionally, rising interest rates resulted in a reduction in loans at their floor rates.
Average investments for the three months ended March 31, 2018 increased $22.8 million compared to the average for the three months ended March 31, 2017. The investments portfolio comprised 29.2% of the average interest-earning assets at March 31, 2018 compared to 30.0% of the average interest-earning assets at March 31, 2017. The investments portfolio yield decreased 4 basis points to 2.95% for the three months ended March 31, 2018 compared to 2.99% for the three months ended March 31, 2017. The decrease in yield on the investments portfolio is due to current low market rates on securities purchases compared to the yield on securities paydowns and maturities during the period, as well as increased premium amortization on debt securities resulting from the adoption of ASU No. 2017-08, Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20) - Premium Amortization on Purchased Callable Debt Securities. Also, the effect on non-taxable securities from the Tax Act further reduced yield for 2018.
Average total deposits for the three months ended March 31, 2018 increased $1.4 billion compared to the average for the three months ended March 31, 2017. The increase is due to an increase of $228.1 million in non-interest-bearing deposits and an increase of $1.1 billion in interest-bearing deposits. The increase in interest-bearing deposits was primarily due to health savings account deposit growth. The average cost of deposits increased 7 basis points to 0.34% for the three months ended March 31, 2018 from 0.27% the three months ended March 31, 2017. The average cost of deposits increased due to pricing shifts resulting from rising interest rates on some products. Higher cost time deposits, increased to 14.3% for the three months ended March 31, 2018 from 12.6% for the three months ended March 31, 2017, as a percentage to total interest-bearing deposits.
Average total borrowings for the three months ended March 31, 2018 decreased $854.1 million compared to the average for the three months ended March 31, 2017. Average securities sold under agreements to repurchase and other borrowings decreased $29.4 million, and average FHLB advances decreased $825.0 million as utilization of advances maturing within one year declined. The average cost of borrowings increased 59 basis points to 2.25% for the three months ended March 31, 2018 from 1.66% for the three months ended March 31, 2017. The increase in the average cost of borrowings was largely a result of the increasing federal funds rate.
Cash flow hedges impacted the average cost of borrowings as follows:
| Three months ended March 31, |
| (In thousands) | 2018 | 2017 |
| Interest rate swaps on FHLB advances | $ | 1,630 | $ | 1,768 |
| Interest rate swaps on senior fixed-rate notes | 76 | 76 |
| Interest rate swaps on brokered CDs and deposits | 117 | 195 |
| Net increase to interest expense on borrowings | $ | 1,823 | $ | 2,039 |

Provision for Loan and Lease Losses
Management performs a quarterly review of the loan and lease portfolio to determine the adequacy of the ALLL. At March 31, 2018 the ALLL totaled $205.3 million, or 1.15% of total loans and leases, as compared to $200.0 million, or 1.14% of total loans and leases at December 31, 2017.
Several factors are considered when determining the level of the ALLL, 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 $5.6 million for the three months ended March 31, 2018, compared to $5.7 million for the three months ended March 31, 2017.
The provision for loan and lease losses of $11.0 million for the three months ended March 31, 2018, an increase of $0.5 million compared to the three months ended March 31, 2017.

| Total non-interest income | $ | 68,747 | $ | 63,042 | $ | 5,705 | 9.0 | % |

Comparison to Prior Year Quarter
Total non-interest income was $68.7 million for the three months ended March 31, 2018, an increase of $5.7 million from the three months ended March 31, 2017. The increase was primarily attributable to higher deposit service fees, and other income, primarily offset by lower mortgage banking activities.
Deposit service fees totaled $40.5 million for the three months ended March 31, 2018, compared to $37.0 million for the three months ended March 31, 2017. The increase was a result of higher checking account service charges and credit card interchange attributable to health savings account growth and usage activity.
Mortgage banking activities totaled $1.1 million for the three months ended March 31, 2018, compared to $2.3 million for the three months ended March 31, 2017. The decrease was primarily driven by lower originations and lower volume in loans held for sale.
Other income totaled $8.7 million for the three months ended March 31, 2018, compared to $5.7 million for the three months ended March 31, 2017. The increase was primarily due to higher client hedging activities and break-funding revenue.

| Total non-interest expense | $ | 171,615 | $ | 163,784 | $ | 7,831 | 4.8 | % |

Comparison to Prior Year Quarter
Total non-interest expense was $171.6 million for the three months ended March 31, 2018, an increase of $7.8 million, from the three months ended March 31, 2017. The increase was primarily attributable to compensation and benefits, and technology and equipment, primarily offset by decreases in marketing and occupancy.
Compensation and benefits totaled $94.8 million for the three months ended March 31, 2018, compared to $87.5 million for the three months ended March 31, 2017. The increase was primarily due to strategic hires and annual merit which led to higher compensation, incentives and payroll taxes.
Occupancy totaled $15.1 million for the three months ended March 31, 2018, compared to $16.2 million for the three months ended March 31, 2017. The decrease was primarily due to charges related to facility optimization in 2017.
Technology and equipment totaled $23.9 million for the three months ended March 31, 2018, compared to $21.6 million for the three months ended March 31, 2017. The increase was primarily due to higher depreciation.
Marketing totaled $3.6 million for the three months ended March 31, 2018 compared to $5.4 million for the three months ended March 31, 2017. The decrease was primarily due to lower advertising and promotion.
Income Taxes
Webster recognized income tax expense of $20.1 million reflecting an effective tax rate of 20.0% for the three months ended March 31, 2018, compared to $22.0 million, or 27.0%, respectively, for the three months ended March 31, 2017.
The decreases in both tax expense and the effective tax rate for the three months ended March 31, 2018 as compared to 2017 principally reflect the reduction of the U.S. corporate tax rate effective in 2018, as a result of the Tax Act enacted in 2017.

Segment Reporting
Webster’s operations are organized into three reportable segments that represent its primary businesses - Commercial Banking, HSA Bank, and Community Banking. These three segments reflect how executive management responsibilities are assigned, the primary businesses, the products and services provided, the type of customer served, and how discrete financial information is currently evaluated. The Corporate Treasury unit of the Company, along with adjustments required to reconcile profitability metrics to amounts reported in accordance with GAAP, are included in the Corporate and Reconciling category.
Commercial Banking is comprised of Commercial Banking and Private Banking operating segments.
Commercial Banking provides commercial and industrial lending and leasing, commercial real estate lending, and treasury and payment solutions. Specifically, Webster Bank deploys lending through middle market, commercial real estate, equipment financing, asset-based lending and specialty lending units. These groups utilize a relationship approach model throughout its footprint when providing lending, deposit, and cash management services to middle market companies. In addition, Commercial Banking serves as a referral source within Commercial Banking and to the other lines of business.
Private Banking provides local, full relationship banking that serves high net worth clients, not-for-profit organizations, and business clients for asset management, financial planning services, trust services, loan products, and deposit products. These client relationships generate fee revenue on assets under management or administration, while a majority of the relationships also include lending and/or deposit accounts which provide net interest income and other ancillary fees.
HSA Bank offers a comprehensive consumer - directed healthcare solution that includes, health savings accounts, health reimbursement accounts, flexible spending accounts, and other financial solutions. Health savings accounts are used in conjunction with high deductible health plans in order to facilitate tax advantages for account holders with respect to health care spending and retirement savings, in accordance with applicable laws. Health savings accounts are offered through employers for the benefit of their employees or directly to individual consumers and are distributed nationwide directly as well as through national and regional insurance carriers, benefit consultants and financial advisors.
HSA Bank deposits provide long duration low-cost funding that is used to minimize the Company’s use of wholesale funding in support of the Company’s loan growth. As such, net interest income represents the difference between a funding credit allocation, reflecting the value of the duration funding, and the interest paid on deposits. In addition, non-interest revenue is generated predominantly through service fees and interchange income.
Community Banking is comprised of Personal Banking and Business Banking operating segments.
Through a distribution network, consisting of 167 banking centers and 333 ATMs, a customer care center, and a full range of web and mobile-based banking services, it serves consumer and business customers primarily throughout southern New England and into Westchester County, New York.
Personal Banking offers consumer deposit and fee-based services, residential mortgages, home equity lines/loans, unsecured consumer loans, and credit card products. In addition, investment and securities-related services, including brokerage and investment advice is offered through a strategic partnership with LPL Financial Holdings Inc. (LPL), a broker dealer registered with the SEC, a registered investment advisor under federal and applicable state laws, a member of the Financial Industry Regulatory Authority (FINRA), and a member of the Securities Investor Protection Corporation (SIPC). Webster Bank has employees located throughout its banking center network, who, through LPL, are registered representatives.
Business Banking offers credit, deposit, and cash flow management products to businesses and professional service firms with annual revenues of up to $25 million. This group builds broad customer relationships through business bankers and business certified banking center managers, supported by a team of customer care center bankers and industry and product specialists.
Description of Segment Reporting Methodology
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 category.
48
Webster allocates interest income and interest expense to each business, while also transferring the primary interest rate risk exposures to the Corporate and Reconciling category, using a matched maturity funding concept called FTP. 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 ALCO.
Webster allocates the provision for loan and lease losses to each reportable segment based on management’s estimate of the inherent loss content in each of the specific loan and lease portfolios. Management believes the reserve level is adequate to cover inherent losses in each reportable segment. For additional discussion related to asset quality metrics, see the "Asset Quality" section elsewhere within this report.
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.
Beginning in 2018, income tax expense is estimated for each reportable segment individually. The 2017 income tax expense was estimated for all segments using the consolidated effective tax rate. This change in the estimate of income tax expense reflects an estimate of full profitability for each of the individual business segments based on the nature of their operations.

Loan originations in the three months ended March 31, 2018 and 2017 were $307.0 million and $465.5 million, respectively. The $159 million decrease in originations was driven by a decrease in originations of residential mortgages, home equity and other consumer loans.
Deposits increased $103.1 million at March 31, 2018 compared to December 31, 2017, due to growth in time deposits partially offset by lower balances in cyclical business and consumer transaction accounts.

Interest bearing deposits increased 3.0%, during the period, due to growth in health savings and money market accounts.
At March 31, 2018, total shareholders' equity of $2.7 billion increased $14.2 million compared to total shareholders' equity of $2.7 billion at December 31, 2017. Changes in shareholders' equity for the three months ended March 31, 2018 included increases of $80.2 million in net income and $3.3 million for share-based award activity, partially offset by $24.1 million in common dividends, $2.0 million in preferred dividends, and $18.3 million purchases of treasury stock at cost.
The quarterly cash dividend to shareholders has been increased to $0.26 per common share since January 30, 2018. See the selected financial highlights under the "Results of Operations" section and Note 10: Regulatory Matters in the Notes to Condensed Consolidated Financial Statements contained elsewhere in this report for information on regulatory capital levels and ratios.
Investment Securities
Webster Bank's investment securities are 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 OCC may establish additional individual limits on a certain type of investment if the concentration in such investment presents a safety and soundness concern. In addition to the Bank, Webster Financial Corporation (the Holding Company) also may directly hold investment securities from time-to-time.
Webster maintains, through its Corporate Treasury Unit, investment securities that are primarily used to provide a source of liquidity for operating needs, to generate interest income, and as a means to manage interest-rate risk. Investment securities are classified into two major categories, available-for-sale and held-to-maturity. Available-for-sale consists primarily of U.S Treasury Bills, Agency CMO, Agency MBS, Agency CMBS, CMBS, CLO, Single issuer-trust preferred, and Corporate debt. Held-to-maturity consists primarily of Agency CMO, Agency MBS, Agency CMBS, municipal bonds and notes, CMBS, and Private label MBS. At March 31, 2018, the Company had no holdings in obligations of individual states, counties, or municipalities which exceeded 10% of consolidated shareholders’ equity.
The combined carrying value of investment securities totaled $7.2 billion and $7.1 billion at March 31, 2018 and December 31, 2017, respectively. Available-for-sale investment securities increased by $135.5 million, primarily due to principle purchase activity for Agency MBS more than offsetting principal paydowns in the portfolio. Held-to-maturity investment securities decreased by $79.1 million, primarily due to principle paydowns exceeding purchase activity. On a tax-equivalent basis, the yield in the investment securities portfolio was 2.91% for the three months ended March 31, 2018 compared to 2.98% for the three months ended March 31, 2017.
The Company held $5.9 billion in investment securities that are in an unrealized loss position at March 31, 2018. Approximately $3.0 billion of this total has been in an unrealized loss position for less than twelve months, while the remainder, $2.8 billion, has been in an unrealized loss position for twelve months or longer. The total unrealized loss was $206.9 million at March 31, 2018. 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 investment securities before the recovery of their cost basis. To the extent that credit movements and other related factors influence the fair value of its investment securities, the Company may be required to record impairment charges for OTTI in future periods.

| Total loans and leases | $ | 17,805,575 | 100.0 | $ | 17,523,858 | 100.0 |

Total residential loans were $4.4 billion at March 31, 2018, a decrease of $31.0 million from December 31, 2017. The net decrease is a result of net principal paydowns exceeding the originations to the portfolio.
Total consumer loans were $2.5 billion at March 31, 2018, a decrease of $67.7 million from December 31, 2017. The net decrease is primarily due to continued net principal paydowns within the home equity lines and auto loan portfolios exceeding originations.
Total commercial loans were $5.8 billion at March 31, 2018, an increase of $393.0 million from December 31, 2017. The net increase primarily related to originations of $654.5 million, partially offset by payments and payoffs.
Total commercial real estate loans were $4.5 billion at March 31, 2018, a increase of $20.7 million from December 31, 2017. The increase is a result of originations of $239.9 million, partially offset by payments and payoffs.
Equipment financing loans and leases were $515.3 million at March 31, 2018, a decrease of $30.5 million from December 31, 2017. The net decrease was primarily related to scheduled amortization and higher prepayments, partially offset by originations of $27.0 million.
Asset Quality
Management maintains asset quality within established risk tolerance levels through its underwriting standards, servicing, and management of loan and lease performance. Loans and leases, particularly where a heightened risk of loss has been identified, are regularly monitored to mitigate further deterioration which could potentially impact key measures of asset quality in future periods. Past due loans and leases, non-performing assets, and credit loss levels are considered to be key measures of asset quality.
The following table provides key asset quality ratios:
| At March 31, 2018 | At December 31, 2017 |
| Non-performing loans and leases as a percentage of loans and leases | 0.75 | % | 0.72 | % |
| Non-performing assets as a percentage of loans and leases plus OREO | 0.79 | 0.76 |
| Non-performing assets as a percentage of total assets | 0.52 | 0.50 |
| ALLL as a percentage of non-performing loans and leases | 152.95 | 158.00 |
| ALLL as a percentage of loans and leases | 1.15 | 1.14 |
| Net charge-offs as a percentage of average loans and leases (1) | 0.13 | 0.20 |
| Ratio of ALLL to net charge-offs (1) | 9.09x | 5.68x |

| (1) | Calculated for the March 31, 2018 period based on the year-to-date net charge-offs, annualized. |

55
Potential Problem Loans and Leases
Potential problem loans and leases are defined by management as certain loans and leases that, for:
| • | commercial, commercial real estate, and equipment financing are performing loans and leases classified as Substandard and have a well-defined weakness that could jeopardize the full repayment of the debt; and |

| • | residential and consumer are performing loans 60-89 days past due and accruing. |

Potential problem loans and leases exclude loans and leases past due 90 days or more and accruing, non-accrual loans and leases, and TDRs.
Management monitors potential problem loans and leases due to a higher degree of risk associated them. The current expectation of probable losses is included in the ALLL, however management cannot predict whether these potential problem loans and leases ultimately will become non-performing or result in a loss. The Company had potential problem loans and leases of $269.4 million at March 31, 2018 compared to $271.5 million at December 31, 2017.
Past Due Loans and Leases
The following table provides information regarding loans and leases past due 30 days or more and accruing income:

| Total | 41,636 | 0.23 | 45,770 | 0.26 |
| Deferred costs and unamortized premiums, net | 129 | 77 |
| Total loans and leases over 30 days past due and accruing income | $ | 41,765 | $ | 45,847 |

| (1) | Represents the principal balance of loans and leases over 30 days past due and accruing income as a percentage of the outstanding principal balance within the comparable loan and lease category, and which excludes the impact of deferred costs and unamortized premiums. |

| (2) | Loans and leases past due 90 days and accruing includes commercial non-mortgage and commercial real estate for the periods presented. |

The balance of loans and leases past due 30 days or more and accruing income decreased $4.1 million at March 31, 2018 compared to December 31, 2017 and was centered in commercial real estate and consumer home equity. The ratio of loans and leases past due 30 days or more and accruing income as a percentage of loans and leases declined to 0.23% at March 31, 2018 as compared to 0.26% at December 31, 2017.

| (2) | Includes non-accrual TDRs of $77.9 million at March 31, 2018 and $74.3 million at December 31, 2017. |

Non-performing assets increased $7.4 million at March 31, 2018 compared to December 31, 2017. The increase in non-performing assets at March 31, 2018 is primarily due to one matured middle market loan that migrated to non-accrual during the quarter while the Bank works with the customer on a renewal, partly offset by improvement in Residential non-accruals during the period. As a result, overall non-performing assets as a percentage of total assets increased to 0.52% at March 31, 2018 as compared to 0.50% at December 31, 2017.
The following table provides detail of non-performing loan and lease activity:

57
Impaired Loans and Leases
Loans and leases are considered impaired when, based on current information and events, it is probable the Company will be unable to collect all amounts due in accordance with the original contractual terms of the loan agreement, including scheduled principal and interest payments. Impairment is evaluated on a pooled basis for smaller-balance homogeneous residential, consumer loans and small business loans. Commercial, commercial real estate, and equipment financing loans and leases over a specific dollar amount and all TDR are evaluated individually for impairment.
At March 31, 2018, there were 1,564 impaired loans and leases with a recorded investment balance of $248.5 million, which included loans and leases of $102.0 million with an impairment allowance of $17.6 million. This compares to 1,606 impaired loans and leases with a recorded investment balance of $246.8 million, which included loans and leases of $105.4 million, with an impairment allowance of $16.6 million at December 31, 2017. For additional information, see Note 4: Loans and Leases in the Notes to Condensed Consolidated Financial Statements contained elsewhere in this report.
Troubled Debt Restructurings
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. Common modifications include material changes in covenants, pricing, and forbearance. 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 six months. Commercial TDRs are evaluated on a case-by-case basis for determination of accrual status. Loans qualify for return to accrual status once they have demonstrated performance with the restructured terms of the loan agreement for a minimum of six months. Initially, all TDRs are reported as impaired. Generally, a TDR is classified as an impaired loan and reported as a TDR for the remaining life of the loan. Impaired and TDR classification may be removed if the borrower demonstrates compliance with the modified terms for a minimum of six months and through 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.
The following tables provide information for TDRs:
| Three months ended March 31, |
| (In thousands) | 2018 | 2017 |
| Beginning balance | $ | 221,404 | $ | 223,528 |
| Additions | 6,593 | 8,160 |
| Paydowns/draws | (7,053 | ) | (3,105 | ) |
| Charge-offs | (725 | ) | (2,034 | ) |
| Transfers to OREO | (681 | ) | (488 | ) |
| Ending balance | $ | 219,538 | $ | 226,061 |

| (In thousands) | At March 31, 2018 | At December 31, 2017 |
| Accrual status | $ | 141,608 | $ | 147,113 |
| Non-accrual status | 77,930 | 74,291 |
| Total recorded investment of TDRs | $ | 219,538 | $ | 221,404 |
| Specific reserves for TDRs included in the balance of ALLL | $ | 13,874 | $ | 12,384 |
| Additional funds committed to borrowers in TDR status | 3,347 | 2,736 |

Overall, TDR balances decreased $1.9 million at March 31, 2018 compared to December 31, 2017. The March 31, 2018 specific reserves for TDRs declined from year end, and reflects management’s current assessment of reserve requirements.

Allowance for Loan and Lease Losses Methodology
The ALLL policy is considered a critical accounting policy. Executive management reviews and advises on the adequacy of the ALLL reserve, which is maintained at a level deemed sufficient by management to cover probable losses inherent within the loan and lease portfolios.
The quarterly process for estimating probable losses is based on predictive models, to measure the current risk profile of loan portfolio and combines other quantitative and qualitative factors together with the impairment reserve to determine the overall reserve requirement. Management's judgment and assumptions influence loss estimates and ALLL balances. Quantitative and qualitative factors that management considers include factors such as the nature and volume of portfolio growth, national and regional economic conditions and trends, 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 at March 31, 2018.
The Company’s methodology for assessing an appropriate level of the ALLL includes three key elements:
| • | Impaired loans and leases are either analyzed on an individual or pooled basis and assessed for specific reserves measured based on the present value of expected future cash flows discounted at the effective interest rate of the loan or lease, except that as a practical expedient, impairment may be measured based on a loan or lease's observable market price, or the fair value of the collateral, if the loan or lease is collateral dependent. A loan or lease is collateral dependent if the repayment of the loan or lease is expected to be provided solely by the underlying collateral. The Company considers the pertinent facts and circumstances for each impaired loan or lease when selecting the appropriate method to measure impairment and evaluates, on a quarterly basis, each selection to ensure its continued appropriateness. |

| • | Loans and leases that are not considered impaired and have similar risk characteristics, are segmented into homogeneous pools and modeled using quantitative methods. The Company's loss estimate for its commercial portfolios utilizes an expected loss methodology that is based on PD and LGD models. The PD and LGD models are based on borrower and facility risk ratings assigned to each loan and are updated throughout the year as a borrower's financial condition changes. PD and LGD models are derived using the Company's portfolio specific historic data and are refreshed annually. Residential and consumer portfolio loss estimates are based on roll rate models that utilize the Company's historic delinquency and default data. For each segmentation the loss estimates incorporate a loss emergence period (LEP) model which represents an amount of time between when a loss event first occurs to when it is charged-off. An LEP is determined for each loan type based on the Company's historical experience and is reassessed at least annually. |

| • | The Company also considers qualitative factors, consistent with interagency regulatory guidance, that are not explicitly factored in the quantitative models but that can have an incremental or regressive impact on losses incurred in the current loan and lease portfolio. |

Commercial loans are underwritten after evaluating and understanding the borrower’s ability to operate and service its debt. Underwriting standards are designed to focus on and support 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. Management regularly monitors the cash flows of borrowers as results 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. 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. Management closely monitors these loans with on-site inspections by third-party professionals and the Company's internal staff.
59
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 and non-qualified mortgage loans as defined by the Consumer Financial Protection Bureau rules that went into effect on January 10, 2014.
At March 31, 2018 the ALLL was $205.3 million compared to $200.0 million at December 31, 2017. The increase of $5.4 million in the reserve at March 31, 2018 compared to December 31, 2017 is primarily due to growth in commercial banking and a net increase in reserves for impaired loans. The ALLL reserve remains adequate to cover inherent losses in the loan and lease portfolios. ALLL as a percentage of loans and leases, also known as the reserve coverage, increased to 1.15% at March 31, 2018 from 1.14% at December 31, 2017, reflecting an updated assessment of inherent losses and impaired reserves. ALLL as a percentage of non-performing loans and leases decreased to 152.95% at March 31, 2018 from 158.00% at December 31, 2017.
The following table provides an allocation of the ALLL by portfolio segment:
| At March 31, 2018 | At December 31, 2017 |
| (Dollars in thousands) | Amount | % (1) | Amount | % (1) |
| Residential | $ | 18,777 | 0.42 | $ | 19,058 | 0.42 |

The following table provides a summary of net charge-offs (recoveries) to average loans and leases by category:
| Three months ended March 31, |
| 2018 | 2017 |
| (Dollars in thousands) | Amount | % (1) | Amount | % (1) |
| Residential | $ | 532 | 0.05 | $ | 495 | 0.05 |
| Consumer | 3,631 | 0.57 | 5,151 | 0.77 |
| Commercial | 1,380 | 0.10 | (199 | ) | (0.02) |
| Commercial real estate | 75 | 0.01 | 95 | 0.01 |
| Equipment financing | 27 | 0.02 | 171 | 0.11 |
| Net charge-offs | $ | 5,645 | 0.13 | $ | 5,713 | 0.13 |

| (1) | Net charge-offs (recoveries) to average loans and leases, percentage calculated based on period-to-date activity, annualized. |

Net charge-offs decreased $0.1 million for the three months ended March 31, 2018 as compared to the same period in 2017. The decrease for the three month period is primarily due to a decrease in consumer charge-offs partly offset by an increase in commercial charge-offs. 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.

Sources of Funds and Liquidity
Sources of Funds. The primary source of Webster Bank’s cash flow for use in lending and meeting its general operational needs is deposits. Operating activities, such as loan and mortgage-backed securities repayments, and other investment securities sale proceeds and maturities, also provide cash flow. While scheduled loan and investment security 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. Additional sources of funds are provided by FHLB advances or other borrowings.
Federal Home Loan Bank and Federal Reserve Bank Stock. Webster Bank is a member of the Federal Home Loan Bank System, which consists of eleven 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 sources of funds and liquidity 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. The FHLB has initiated a process to redeem the holdings of its member banks in excess of their membership and activity requirements, based on current conditions. As a result, Webster Bank held $74.6 million of FHLB capital stock at March 31, 2018 compared to $100.9 million at December 31, 2017, for its membership and for outstanding advances and other extensions of credit. On March 2, 2018, the FHLB paid a cash dividend equal to an annual yield of 4.99%.
Additionally, Webster Bank is required to hold FRB stock equal to 6% of its capital and surplus of which 50% is paid. The remaining 50% is subject to call when deemed necessary by the FRB. 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 March 31, 2018 and December 31, 2017, Webster Bank held $50.7 million of FRB capital stock. A semi-annual dividend payment from the FRB is calculated as the lesser of three percent or yield of the 10-year Treasury note auctioned at the last auction held prior to the payment of the dividend.
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 for both consumer and business customers throughout 167 banking centers within its primary market area. Webster Bank manages the flow of funds in its deposit accounts and provides a variety of accounts and rates consistent with 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 $21.4 billion at March 31, 2018 compared to $21.0 billion at December 31, 2017. The increase is predominately related to an increase in health savings accounts of $0.4 billion. 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 March 31, 2018 and December 31, 2017, FHLB advances totaled $1.2 billion and $1.7 billion, respectively. Webster Bank had additional borrowing capacity from the FHLB of approximately $3.0 billion at March 31, 2018 compared to approximately $2.6 billion at December 31, 2017. Webster Bank also had additional borrowing capacity at the FRB of approximately $0.4 billion at March 31, 2018 and $0.5 billion at December 31, 2017. In addition, unpledged investment securities of $4.2 billion at March 31, 2018 could have been used to increase borrowing capacity by approximately $3.9 billion at the FHLB or approximately $4.0 billion at the FRB, or alternatively used for collateral on other borrowings, such as repurchase agreements.
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 $2.4 billion at March 31, 2018 compared to $2.5 billion at December 31, 2017. Borrowings represented 8.8% and 9.6% of total assets at March 31, 2018 and December 31, 2017, respectively. The reduction in borrowings was the net result of decreased FHLB advances maturing within one year, being nearly offset by increased Fed funds purchased balances. For additional information, see Note 8: Borrowings in the Notes to Condensed Consolidated Financial Statements contained elsewhere in this report.
62
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 investment securities, which can be sold or utilized to secure funding, and new deposits. Webster is committed to maintaining a strong, increasing base of core deposits, consisting of demand, checking, savings, health savings, and money market accounts, 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. Net cash provided by operating activities was $132.3 million for the three months ended March 31, 2018 as compared to $144.1 million for the three months ended March 31, 2017. The decrease is significantly a result reduced mortgage banking activities during the current period.
Holding Company Liquidity. The primary source of liquidity at the Holding Company is dividends from Webster Bank. Webster Bank paid $100 million in dividends to the Holding Company during the three months ended March 31, 2018. 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 its common stock, and purchases of available-for-sale investment securities. There are certain restrictions on the payment of dividends by Webster Bank to the Holding Company, which is described in the section captioned "Supervision and Regulation" in Item 1 of Webster’s 2017 Form 10-K. At March 31, 2018, there was $238.7 million of retained earnings available for the payment of dividends by Webster Bank to the Holding Company.
The Company has a common stock repurchase program authorized by the Board of Directors, with $91.7 million of remaining repurchase authority at March 31, 2018. In addition, Webster periodically acquires common shares outside of the repurchase program related to stock compensation plan activity. The Company records the purchase of shares of common stock at cost based on the settlement date for these transactions. During the three months ended March 31, 2018, a total of 324,227 shares of common stock were repurchased for approximately $18.3 million, of which 215,000 shares were purchased under the common stock repurchase program at a cost of approximately $12.2 million, and 109,227 shares were purchased, at market prices, related to stock compensation plan activity for a cost of approximately $6.1 million.
Webster Bank Liquidity. Webster Bank's primary source of funding is core deposits. The primary use of this funding is for loan portfolio growth. Including time deposits, Webster Bank had a loan to total deposit ratio of 83.3% and 83.5% at March 31, 2018 and December 31, 2017, respectively.
Webster Bank is required by OCC regulations 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 March 31, 2018. The Company has a detailed liquidity contingency plan designed to respond to liquidity concerns in a prompt and comprehensive manner. The plan 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 March 31, 2018, Webster Bank was in compliance with all applicable capital requirements and exceeded the FDIC requirements for a well-capitalized institution. See Note 10: 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 Financial Corporation 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 three months ended March 31, 2018, Webster did not engage in any off-balance sheet transactions that would have a material effect on its financial condition. For additional information, see Note 18: Commitments and Contingencies in the Notes to Condensed Consolidated Financial Statements contained elsewhere in this report.
63
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, interest rate sensitivity is monitored on an ongoing basis by ALCO.
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 March 31, 2018 and December 31, 2017, 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 |
| March 31, 2018 | N/A | (5.0)% | 3.0% | 5.6% |
| December 31, 2017 | N/A | (5.9)% | 3.4% | 6.4% |

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 March 31, 2018 and December 31, 2017, might have on Webster’s pre-tax, pre-provision net revenue (PPNR) for the subsequent twelve month period compared to PPNR assuming no change in interest rates:
| PPNR | -200bp | -100bp | +100bp | +200bp |
| March 31, 2018 | N/A | (8.6)% | 4.6% | 8.6% |
| December 31, 2017 | N/A | (10.4)% | 5.3% | 9.9% |

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 March 31, 2018 and December 31, 2017 assumed a Fed Funds rate of 1.75% and 1.50% respectively. Asset sensitivity for both NII and PPNR on March 31, 2018 was lower as compared to December 31, 2017, primarily due to increases in the ten-year swap rate and the resulting impact on the constant prepayment rates (CPRs) in mortgage related investments.
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 yield curve twists or immediate non-parallel changes in interest rates might have on Webster’s NII for the subsequent twelve month period starting March 31, 2018 and December 31, 2017:
| Short End of the Yield Curve | Long End of the Yield Curve |
| NII | -100bp | -50bp | +50bp | +100bp | -100bp | -50bp | +50bp | +100bp |
| March 31, 2018 | (7.9)% | (3.8)% | 1.9% | 3.7% | (3.2)% | (1.3)% | 1.0% | 1.7% |
| December 31, 2017 | (8.5)% | (4.3)% | 2.0% | 3.9% | (3.9)% | (1.7)% | 1.3% | 2.3% |

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 March 31, 2018 and December 31, 2017:
| Short End of the Yield Curve | Long End of the Yield Curve |
| PPNR | -100bp | -50bp | +50bp | +100bp | -100bp | -50bp | +50bp | +100bp |
| March 31, 2018 | (13.5)% | (6.4)% | 2.8% | 5.4% | (3.6)% | (1.8)% | 1.6% | 2.9% |
| December 31, 2017 | (14.8)% | (7.5)% | 2.9% | 5.7% | (4.8)% | (2.2)% | 2.2% | 4.0% |

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.
Sensitivity to increases in the short end of the yield curve for NII and PPNR remained essentially unchanged from December 31, 2017. Sensitivity to decreases in the short end of the yield curve for NII and PPNR are less negative from December 31, 2017 due to the benefit of deposit rate decreases should short-term rates begin to fall. Sensitivity to increases in the long end of the yield curve declined in March 31, 2018 verses December 31, 2017 due to increases in the ten-year swap rate and the resulting impact on the CPRs in mortgage related investments. Conversely, sensitivity to decreases in the long end of the yield curve are less negative as of March 31, 2018 verses December 31, 2017.

The following table summarizes the estimated economic value of assets, liabilities, and off-balance sheet contracts at March 31, 2018 and December 31, 2017 and the projected change to economic values if interest rates instantaneously increase or decrease by 100 basis points:
| (Dollars in thousands) | BookValue | EstimatedEconomicValue | Estimated Economic Value Change |
| -100 bp | +100 bp |
| March 31, 2018 |
| Assets | $ | 26,752,147 | $ | 26,135,008 | $ | 551,685 | $ | (662,758 | ) |
| Liabilities | 24,036,005 | 22,488,183 | 701,215 | (602,337 | ) |
| Net | $ | 2,716,142 | $ | 3,646,825 | $ | (149,530 | ) | $ | (60,421 | ) |
| Net change as % base net economic value | (4.1 | )% | (1.7 | )% |
| December 31, 2017 |
| Assets | $ | 26,487,645 | $ | 25,971,043 | $ | 505,148 | $ | (631,744 | ) |
| Liabilities | 23,785,687 | 22,509,322 | 729,967 | (624,789 | ) |
| Net | $ | 2,701,958 | $ | 3,461,721 | $ | (224,819 | ) | $ | (6,955 | ) |
| Net change as % base net economic value | (6.5 | )% | (0.2 | )% |

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 negative 0.7 years at March 31, 2018. At December 31, 2017, the duration gap was negative 0.9 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 impact of rising short-term interest rates on periodic/floating interest rate loan portfolios as of March 31, 2018.
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 March 31, 2018 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.
For a detailed description of the Company's asset/liability management process, refer to the section captioned "Asset/Liability Management and Market Risk" in Item 7. Management's Discussion And Analysis Of Financial Condition And Results Of Operations included in its Form 10-K, for the year ended December 31, 2017.
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
The required information is set forth above, in Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations, see the section captioned "Asset/Liability Management and Market Risk," which is incorporated herein by reference.
ITEM 4. CONTROLS AND PROCEDURES
The Company has 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 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, were effective as of March 31, 2018.
There were no changes made to 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.
66
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 three months ended March 31, 2018, 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, 2017.
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 Financial Corporation's 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 March 31, 2018:

| (1) | On October 24, 2017, the Company's Board of Directors approved a common 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. The program 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 March 31, 2018, 109,227 shares were acquired outside of the repurchase program related to stock compensation plan activity, at market prices.
| (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, as permitted by securities laws and other legal requirements. There remain 8,752 outstanding warrants to purchase a share (1:1) of the Company's common stock, 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 10: Regulatory Matters in the Notes to Condensed Consolidated Financial Statements contained elsewhere in this report for additional information.
The Company has 6,000,000 outstanding Depository Shares, each representing 1/1000th interest in a share of 5.25% Series F Non-Cumulative Perpetual Preferred Stock, par value $.01 per share, with a liquidation preference of $25,000 per share (or $25 per depository share). The Series F Preferred Stock is redeemable at Webster's option, in whole or in part, on December 15, 2022, 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 F 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 F Preferred Stock for the most recently completed dividend period.

Question: What is the percent change in total unrealized losses from December 31, 2017, to March 31, 2018, across all reported investment types such as Agency CMO, Agency MBS, Agency CMBS, Municipal bonds and notes, and CMBS?

Solution:
def solution():
    #Define variables name and value
    unrealized_losses_Agency_CMO_dec = 4.8
    unrealized_losses_Agency_CMO_mar = 7.1
    unrealized_losses_Agency_MBS_dec = 37.4
    unrealized_losses_Agency_MBS_mar = 80.7
    unrealized_losses_Agency_CMBS_dec = 10.0
    unrealized_losses_Agency_CMBS_mar = 20.7
    unrealized_losses_Municipal_dec = 6.6
    unrealized_losses_Municipal_mar = 16.1
    unrealized_losses_CMBS_dec = 0.6
    unrealized_losses_CMBS_mar = 2.9
    total_unrealized_losses_dec = unrealized_losses_Agency_CMO_dec + unrealized_losses_Agency_MBS_dec + unrealized_losses_Agency_CMBS_dec + unrealized_losses_Municipal_dec + unrealized_losses_CMBS_dec
    total_unrealized_losses_mar = unrealized_losses_Agency_CMO_mar + unrealized_losses_Agency_MBS_mar + unrealized_losses_Agency_CMBS_mar + unrealized_losses_Municipal_mar + unrealized_losses_CMBS_mar

    #Do math calculation to get the answer
    percent_change = ((total_unrealized_losses_mar - total_unrealized_losses_dec) / total_unrealized_losses_dec) * 100
    answer = round(percent_change, 2)
    return answer
