FULTON FINANCIAL CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

NOTE 1 – Basis of Presentation

The accompanying unaudited consolidated financial statements of Fulton Financial Corporation (the "Corporation") have been prepared in conformity with U.S. generally accepted accounting principles ("U.S. GAAP") for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and notes required by U.S. GAAP for complete financial statements. The preparation of financial statements in accordance with U.S. 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 revenues and expenses during the period. Actual results could differ from those estimates. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. These consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2015. Operating results for the three months ended March 31, 2016 are not necessarily indicative of the results that may be expected for the year ending December 31, 2016. The Corporation evaluates subsequent events through the date of filing of this Form 10-Q with the Securities and Exchange Commission ("SEC").

Recently Adopted Accounting Standards

The Corporation adopted FASB ASC Update 2015-02, "Consolidation: Amendments to the Consolidation Analysis" effective January 1, 2016. ASC Update 2015-02 changed the way reporting enterprises evaluate whether: (a) they should consolidate limited partnerships and similar entities, (b) fees paid to a decision maker or service provider are variable interests in a variable interest entity ("VIE"), and (c) variable interests in a VIE held by related parties of the reporting enterprise require the reporting enterprise to consolidate the VIE.ASC Update 2015-02 was effective for public business entities' annual and interim reporting periods that began after December 15, 2015, with earlier adoption permitted. The adoption of ASC Update 2015-02 did not have a material impact on the Corporation's consolidated financial statements.

Effective January 1, 2016, the Corporation adopted FASB ASC Update 2015-03, "Interest - Imputation of Interest" and the updated ASC Update 2015-03 with the issuance of ASC Update 2015-15, “Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements.” ASC Update 2015-03 simplifies the presentation of debt issuances costs. Debt issuance costs related to a recognized debt liability will be presented on the balance sheet as a direct deduction from the debt liability, similar to the presentation of debt discounts. Previously under U.S. GAAP, debt issuance costs were reported on the balance sheet as assets. The costs will continue to be amortized to interest expense using the effective interest method. ASC Update 2015-03 was effective for public business entities' annual and interim reporting periods beginning after December 15, 2015, with earlier adoption permitted.The adoption of ASC Update 2015-03 did not have a material impact on the Corporation's consolidated financial statements.

The Corporation prospectively adopted FASB issued ASC Update 2015-05, "Customer's Accounting for Fees Paid in a Cloud Computing Arrangement" effective January 1, 2016. ASC Update 2015-05 provides explicit guidance to determine when a customer's fees paid in a cloud computing arrangement is for the acquisition of software licenses, services, or both. ASC Update 2015-05 was effective for public business entities' annual and interim reporting periods beginning after December 15, 2015, with earlier adoption permitted.The adoption of ASC Update 2015-05 did not have a material impact on the Corporation's consolidated financial statements.

Recently Issued Accounting Standards

In May 2014, the FASB issued ASC Update 2014-09, "Revenue from Contracts with Customers." This standards update establishes a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. The core principle prescribed by this standards update is that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The standard applies to all contracts with customers, except those that are within the scope of other topics in the FASB ASC. The standard also requires significantly expanded disclosures about revenue recognition. For public business entities, ASC Update 2014-09 is effective for interim and annual reporting periods beginning after December 15, 2017. Early application is not permitted. For the Corporation, this standards update is effective with its March 31, 2018 quarterly report on Form 10-Q. The Corporation is currently evaluating the impact of the adoption of ASC Update 2014-09 on its consolidated financial statements.

8

In January 2016, the FASB issued ASC Update 2016-01, "Financial Instruments - Overall: Recognition and Measurement of Financial Assets and Financial Liabilities." ASC Update 2016-01 provides guidance regarding the income statement impact of equity investments held by an entity and the recognition of changes in fair value of financial liabilities when the fair value option is elected. ASC Update 2016-01 is effective for public business entities' annual and interim reporting periods beginning after December 15, 2017, with earlier adoption permitted.The Corporation intends to adopt this standards update effective with its March 31, 2018 quarterly report on Form 10-Q and does not expect the adoption of ASC Update 2016-01 to have a material impact on its consolidated financial statements.

In February 2016, the FASB issued ASC Update 2016-02, "Leases." This standards update states that a lessee should recognize the assets and liabilities that arise from all leases with a term greater than 12 months. The core principle requires the lessee to recognize a liability to make lease payments and a "right-of-use" asset. The accounting applied by the lessor is relatively unchanged. The standards update also requires expanded qualitative and quantitative disclosures. For public business entities, ASC Update 2016-02 is effective for interim and annual reporting periods beginning after December 15, 2018. ASC Update 2016-02 mandates a modified retrospective transition for all entities. Early application is permitted. For the Corporation, this standards update is effective with its March 31, 2019 quarterly report on Form 10-Q. The Corporation is currently evaluating the impact of the adoption of ASC Update 2016-02 on its consolidated financial statements.

In March 2016, the FASB issued ASC Update 2016-09, "Stock Compensation: Improvements to Employee Share-Based Payment Accounting." The purpose of this standards update is to simplify several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liability, and classification on the statement of cash flows. ASC Update 2016-09 is effective for interim and annual reporting periods beginning after December 15, 2016. Early application is permitted. For the Corporation, this standards update is effective with its March 31, 2017 quarterly report on Form 10-Q. The Corporation is currently evaluating the impact of the adoption of ASC Update 2016-09 on its consolidated financial statements.

Reclassifications

Certain amounts in the 2015 consolidated financial statements and notes have been reclassified to conform to the 2016 presentation.

NOTE 2 – Net Income Per Share

Basic net income per share is calculated as net income divided by the weighted average number of shares outstanding.

Diluted net income per share is calculated as net income divided by the weighted average number of shares outstanding plus the incremental number of shares added as a result of converting common stock equivalents, calculated using the treasury stock method. The Corporation’s common stock equivalents consist of outstanding stock options, restricted stock, restricted stock units ("RSUs") and performance-based restricted stock units ("PSUs"). PSUs are required to be included in weighted average shares outstanding if performance measures, as defined in each PSU award agreement, are met as of the end of the period.

A reconciliation of weighted average shares outstanding used to calculate basic net income per share and diluted net income per share follows:

	Three months ended March 31
	2016	2015
	(in thousands)
Weighted average shares outstanding (basic)	173,331	178,471
Impact of common stock equivalents	1,085	986
Weighted average shares outstanding (diluted)	174,416	179,457

For the three months ended March 31, 2016 and 2015, 885,000 and 2.1 million stock options, respectively, were excluded from the diluted net income per share computation as their effect would have been anti-dilutive.

Securities carried at $1.6 billion as of March 31, 2016 and $1.7 billion as of December 31, 2015 were pledged as collateral to secure public and trust deposits and customer repurchase agreements.

Equity securities include common stocks of financial institutions (estimated fair value of $18.2 million at March 31, 2016 and $20.6 million at December 31, 2015) and other equity investments (estimated fair value of $892,000 at March 31, 2016 and $914,000 at December 31, 2015).

As of March 31, 2016, the financial institutions stock portfolio had a cost basis of $13.4 million and an estimated fair value of $18.2 million, including an investment in a single financial institution with a cost basis of $7.4 million and an estimated fair value of $9.1 million. The estimated fair value of this investment accounted for 50.3% of the estimated fair value of the Corporation's investments in the common stocks of publicly traded financial institutions. No other investment in a single financial institution in the financial institutions stock portfolio exceeded 10% of the portfolio's estimated fair value.

The Corporation’s collateralized mortgage obligations and mortgage-backed securities have contractual terms that generally do not permit the issuer to settle the securities at a price less than the amortized cost of the investment. Because the decline in market value of these securities is attributable to changes in interest rates and not credit quality, and because the Corporation does not have the intent to sell and does not believe it will more likely than not be required to sell any of these securities prior to a recovery of their fair value to amortized cost, the Corporation does not consider these investments to be other-than-temporarily impaired as of March 31, 2016.

As of March 31, 2016, all of the auction rate securities (auction rate certificates, or "ARCs"), were rated above investment grade, with approximately $5.5 million, or 6%, "AAA" rated and $91.8 million, or 94%, "AA" rated. All of the loans underlying the ARCs have principal payments which are guaranteed by the federal government. As of March 31, 2016, all ARCs were current and making scheduled interest payments. Based on management’s evaluations, ARCs with an estimated fair value of $97.3 million were not subject to any other-than-temporary impairment charges as of March 31, 2016. The Corporation does not have the intent to sell and does not believe it will more likely than not be required to sell any of these securities prior to a recovery of their fair value to amortized cost, which may be at maturity.

For its investments in equity securities, particularly its investments in stocks of financial institutions, management evaluates the near-term prospects of the issuers in relation to the severity and duration of the impairment. Based on that evaluation and the Corporation’s ability and intent to hold those investments for a reasonable period of time sufficient for a recovery of fair value, the Corporation does not consider those investments with unrealized holding losses as of March 31, 2016 to be other-than-temporarily impaired.

The majority of the Corporation's available for sale corporate debt securities are issued by financial institutions. The following table presents the amortized cost and estimated fair value of corporate debt securities:

Single-issuer trust preferred securities had an unrealized loss of $7.8 million at March 31, 2016. Six of the 19 single-issuer trust preferred securities were rated below investment grade by at least one ratings agency, with an amortized cost of $11.5 million and an estimated fair value of $9.0 million at March 31, 2016. All of the single-issuer trust preferred securities rated below investment grade were rated "BB" or "Ba". Two single-issuer trust preferred securities with an amortized cost of $3.7 million and an estimated fair value of $2.4 million at March 31, 2016 were not rated by any ratings agency.

13

Based on management’s evaluations, corporate debt securities with a fair value of $89.9 million were not subject to any other-than-temporary impairment charges as of March 31, 2016. The Corporation does not have the intent to sell and does not believe it will more likely than not be required to sell any of these securities prior to a recovery of their fair value to amortized cost, which may be at maturity.

Allowance for Credit Losses

The allowance for credit losses consists of the allowance for loan losses and the reserve for unfunded lending commitments. The allowance for loan losses represents management’s estimate of incurred losses in the loan portfolio as of the balance sheet date and is recorded as a reduction to loans. The reserve for unfunded lending commitments represents management’s estimate of incurred losses in its unfunded loan commitments and is recorded in other liabilities on the consolidated balance sheets. The allowance for credit losses is increased by charges to expense, through the provision for credit losses, and decreased by charge-offs, net of recoveries.

The Corporation’s allowance for credit losses includes: (1) specific allowances allocated to loans evaluated for impairment under the FASB's ASC Section 310-10-35; and (2) allowances calculated for pools of loans measured for impairment under FASB ASC Subtopic 450-20.

The Corporation segments its loan portfolio by general loan type, or "portfolio segments," as presented in the table under the heading, "Loans, Net of Unearned Income," above. Certain portfolio segments are further disaggregated and evaluated collectively for impairment based on "class segments," which are largely based on the type of collateral underlying each loan. Commercial loans include loans secured by collateral and unsecured loans. Construction loan class segments include loans secured by commercial real estate, loans to commercial borrowers secured by residential real estate and loans to individuals secured by residential real estate. Consumer loan class segments include direct consumer installment loans and indirect automobile loans.

The following table presents the components of the allowance for credit losses:

(1) The unallocated allowance, which was approximately 4% and 5% of the total allowance for credit losses, respectively, as of March 31, 2016 and March 31, 2015, was, in the opinion of management, reasonable and appropriate given that the estimates used in the allocation process are inherently imprecise.

N/A - Not applicable.

Impaired Loans

A loan is considered to be impaired if it is probable that all amounts will not be collected according to the contractual terms of the loan agreement. Impaired loans consist of all loans on non-accrual status and accruing troubled debt restructurings ("TDRs"). An allowance for loan losses is established for an impaired loan if its carrying value exceeds its estimated fair value. Impaired loans to borrowers with total outstanding commitments greater than or equal to $1.0 million are evaluated individually for impairment. Impaired loans to borrowers with total outstanding commitments less than $1.0 million are pooled and measured for impairment collectively.

Based on an evaluation of all relevant credit quality factors, the Corporation recorded a $1.5 million provision for credit losses during the three months ended March 31, 2016, compared to a $3.7 million negative provision for credit losses for the same period in 2015.

All loans individually evaluated for impairment under FASB ASC Section 310-10-35 are measured for losses on a quarterly basis.

As of March 31, 2016 and December 31, 2015, substantially all of the Corporation’s individually evaluated impaired loans with total outstanding balances greater than or equal to $1.0 million were measured based on the estimated fair value of each loan’s collateral. Collateral could be in the form of real estate, in the case of impaired commercial mortgages and construction loans, or business assets, such as accounts receivable or inventory, in the case of commercial and industrial loans. Commercial and industrial loans may also be secured by real property.

As of March 31, 2016 and 2015, approximately 77% and 78%, respectively, of impaired loans with principal balances greater than or equal to $1.0 million, whose primary collateral is real estate, were measured at estimated fair value using state certified third-party appraisals that had been updated in the preceding 12 months.

When updated appraisals are not obtained for loans evaluated for impairment under FASB ASC Section 310-10-35 that are secured by real estate, fair values are estimated based on the original appraisal values, as long as the original appraisal indicated an acceptable

16

loan-to-value position and, in the opinion of the Corporation's internal credit administration staff, there has not been a significant deterioration in the collateral value since the original appraisal was performed. Original appraisals are typically used only when the estimated collateral value, as adjusted for the age of the appraisal, results in a current loan-to-value ratio that is lower than the Corporation's loan-to-value requirements for new loans, generally less than 70%.

The following table presents total impaired loans by class segment:

As of March 31, 2016 and December 31, 2015, there were $47.8 million and $50.0 million, respectively, of impaired loans that did not have a related allowance for loan loss. The estimated fair values of the collateral securing these loans exceeded their carrying amount, or they were previously charged down to realizable collateral values. Accordingly, no specific valuation allowance was considered to be necessary.

Credit Quality Indicators and Non-performing Assets

The following table presents internal credit risk ratings for real estate - commercial mortgages, commercial - secured loans, commercial - unsecured loans, construction - commercial residential loans and construction - commercial loans:

The following is a summary of the Corporation's internal risk rating categories:

• Pass: These loans do not currently pose undue credit risk and can range from the highest to average quality, depending on the degree of potential risk.

• Special Mention: These loans constitute an undue and unwarranted credit risk, but not to a point of justifying a classification of substandard. Loans in this category are currently acceptable, but are nevertheless potentially weak.

• Substandard or Lower: These loans are inadequately protected by current sound worth and paying capacity of the borrower. There exists a well-defined weakness or weaknesses that jeopardize the normal repayment of the debt.

The risk rating process allows management to identify credits that potentially carry more risk in a timely manner and to allocate resources to managing troubled accounts. The Corporation believes that internal risk ratings are the most relevant credit quality indicator for the class segments presented above. The migration of loans through the various internal risk rating categories is a significant component of the allowance for credit loss methodology, which bases the probability of default on this migration. Assigning risk ratings involves judgment. Risk ratings are initially assigned to loans by loan officers and are reviewed on a regular basis by credit administration staff. The Corporation's loan review officers provide a separate assessment of risk rating accuracy. Ratings may be changed based on the ongoing monitoring procedures performed by loan officers or credit administration staff, or if specific loan review activities identify a deterioration or an improvement in the loan.

The Corporation does not assign internal risk ratings to smaller balance, homogeneous loans, such as home equity, residential mortgage, consumer, lease receivables and construction loans to individuals secured by residential real estate. For these loans, the most relevant credit quality indicator is delinquency status. The migration of loans through the various delinquency status categories is a significant component of the allowance for credit losses methodology for those loans, which bases the probability of default on this migration.

NOTE 6 – Mortgage Servicing Rights

The following table summarizes the changes in mortgage servicing rights ("MSRs"), which are included in other assets on the consolidated balance sheets:

	Three months ended March 31
	2016			2015
	(in thousands)
Amortized cost:
Balance at beginning of period	$	40,944		$	42,148
Originations of mortgage servicing rights	920			1,557
Amortization	(1,669		)	(1,902		)
Balance at end of period	$	40,195		$	41,803

MSRs represent the economic value of existing contractual rights to service mortgage loans that have been sold. Accordingly, actual and expected prepayments of the underlying mortgage loans can impact the value of MSRs. The Corporation accounts for MSRs at the lower of amortized cost or fair value.

The fair value of MSRs is estimated by discounting the estimated cash flows from servicing income, net of expense, over the expected life of the underlying loans at a discount rate commensurate with the risk associated with these assets. Expected life is based on the contractual terms of the loans, as adjusted for prepayment projections. No valuation allowance was necessary as of March 31, 2016 or 2015.

As of March 31, 2016, the estimated fair value of MSRs was $40.8 million, which exceeded their book value.

NOTE 7 – Stock-Based Compensation

The Corporation grants equity awards to employees, consisting of stock options, restricted stock, RSUs and PSUs under its Amended and Restated Equity and Cash Incentive Compensation Plan ("Employee Equity Plan"). In addition, employees may purchase stock under the Corporation’s Employee Stock Purchase Plan. The fair value of equity awards granted to employees is recognized as compensation expense over the period during which employees are required to provide service in exchange for such awards. Compensation expense for PSUs is also recognized over the period during which employees are required to provide service in exchange for such awards, however, compensation expense may vary based on the expectations for actual performance relative to defined performance measures.

The Corporation also grants equity awards to non-employee members of its board of directors under the 2011 Directors’ Equity Participation Plan ("Directors’ Plan"). Under the Directors’ Plan, the Corporation can grant equity awards to non-employee holding company and subsidiary bank directors in the form of stock options, restricted stock or common stock.

Equity awards issued under the Employee Equity Plan are generally granted annually and become fully vested over or after a three-year vesting period. The vesting period for non-performance-based awards represents the period during which employees are required to provide service in exchange for such awards. Equity awards under the Directors' Plan generally vest immediately upon grant. Certain events, as defined in the Employee Equity Plan and the Directors' Plan, result in the acceleration of the vesting of equity awards.

The following table presents compensation expense and the related tax benefits for equity awards recognized in the consolidated statements of income:

	Three months ended March 31
	2016			2015
	(in thousands)
Stock-based compensation expense	$	1,436		$	1,071
Tax benefit	(433		)	(292		)
Stock-based compensation expense, net of tax	$	1,003		$	779

23

Stock option fair values are estimated through the use of the Black-Scholes valuation methodology as of the date of grant. Stock options carry terms of up to ten years. Fair values for restricted stock, RSUs and a majority of PSUs are based on the trading price of the Corporation’s stock on the date of grant and earn dividends during the vesting period, which are forfeitable if the awards do not vest. The fair value of certain PSUs are estimated through the use of the Monte Carlo valuation methodology as of the date of grant.

As of March 31, 2016, the Employee Equity Plan had 11.5 million shares reserved for future grants through 2023, and the Directors’ Plan had approximately 396,000 shares reserved for future grants through 2021.

NOTE 8 – Employee Benefit Plans

The Corporation maintains a defined benefit pension plan ("Pension Plan") for certain employees, which was curtailed in 2008. Contributions to the Pension Plan are actuarially determined and funded annually, if required. Pension Plan assets are invested in: money markets; fixed income securities, including corporate bonds, U.S. Treasury securities and common trust funds; and equity securities, including common stocks and common stock mutual funds.

The net periodic benefit cost for the Corporation’s Pension Plan consisted of the following components:

	Three months ended March 31
	2016			2015
	(in thousands)
Service cost (1)	$	150		$	145
Interest cost	881			851
Expected return on plan assets	(726		)	(752		)
Net amortization and deferral	782			782
Net periodic benefit cost	$	1,087		$	1,026

(1) Service cost was related to administrative costs associated with the plan and was not due to the accrual of additional participant benefits.

The Corporation provides benefits under a postretirement benefits plan ("Postretirement Plan") to certain retirees who were employees of the Corporation prior to January 1, 1998 and retired from employment with the Corporation prior to February 1, 2014.

The net periodic cost (benefit) of the Corporation’s Postretirement Plan consisted of the following components:

	Three months ended March 31
	2016			2015
	(in thousands)
Interest cost	38			52
Net accretion and deferral	(65		)	(65		)
Net periodic benefit	$	(27	)	$	(13	)

The Corporation recognizes the funded status of its Pension Plan and Postretirement Plan on the consolidated balance sheets and recognizes the change in that funded status through other comprehensive income.

NOTE 9 – Derivative Financial Instruments

The Corporation manages its exposure to certain interest rate and foreign currency risks through the use of derivatives. None of the Corporation's outstanding derivative contracts are designated as hedges, and none are entered into for speculative purposes. Derivative instruments are carried at fair value, with changes in fair values recognized in earnings as components of non-interest income and non-interest expense on the consolidated statements of income.

Derivative contracts create counterparty credit risk with both the Corporation's customers and with institutional derivative counterparties. The Corporation manages counterparty credit risk through its credit approval processes, monitoring procedures and obtaining adequate collateral, when the Corporation determines it is appropriate to do so and in accordance with counterparty contracts.

Mortgage Banking Derivatives

In connection with its mortgage banking activities, the Corporation enters into commitments to originate certain fixed rate residential mortgage loans for customers, also referred to as interest rate locks. In addition, the Corporation enters into forward commitments for the future sales or purchases of mortgage-backed securities to or from third-party counterparties to hedge the effect of changes in interest rates on the values of both the interest rate locks and mortgage loans held for sale. Forward sales commitments may also be in the form of commitments to sell individual mortgage loans at a fixed price at a future date. The amount necessary to settle each interest rate lock is based on the price that secondary market investors would pay for loans with similar characteristics, including interest rate and term, as of the date fair value is measured. Gross derivative assets and liabilities are recorded in other assets and other liabilities, respectively, on the consolidated balance sheets, and changes in fair values during the period are recorded in mortgage banking income on the consolidated statements of income.

Interest Rate Swaps

The Corporation enters into interest rate swaps with certain qualifying commercial loan customers to meet their interest rate risk management needs. The Corporation simultaneously enters into interest rate swaps with dealer counterparties, with identical notional amounts and terms. The net result of these interest rate swaps is that the customer pays a fixed rate of interest and the Corporation receives a floating rate. These interest rate swaps are derivative financial instruments that are recorded at their fair value in other assets and other liabilities on the consolidated balance sheets, with changes in fair value during the period recorded in other non-interest expense on the consolidated statements of income.

Foreign Exchange Contracts

The Corporation enters into foreign exchange contracts to accommodate the needs of its customers. Foreign exchange contracts are commitments to buy or sell foreign currency on a future date at a contractual price. The Corporation offsets its foreign exchange contract exposure with customers by entering into contracts with third-party correspondent financial institutions to mitigate its exposure to fluctuations in foreign currency exchange rates. The Corporation also holds certain amounts of foreign currency with international correspondent banks. The Corporation's policy limits the total net foreign currency open positions, which includes all outstanding contracts and foreign account balances, to $500,000. Gross derivative assets and liabilities are recorded in other assets and other liabilities, respectively, on the consolidated balance sheets, with changes in fair values during the period recorded within other service charges and fees on the consolidated statements of income.

Fair Value Option

U.S. GAAP permits entities to measure many financial instruments and certain other items at fair value and requires certain disclosures for amounts for which the fair value option is applied. The Corporation has elected to measure mortgage loans held for sale at fair value to more accurately reflect the financial results of its mortgage banking activities in its consolidated financial statements. Derivative financial instruments related to these activities are also recorded at fair value, as noted above. The Corporation

26

determines fair value for its mortgage loans held for sale based on the price that secondary market investors would pay for loans with similar characteristics, including interest rate and term, as of the date fair value is measured. Changes in fair values during the period are recorded as components of mortgage banking income on the consolidated statements of income. Interest income earned on mortgage loans held for sale is classified in interest income on the consolidated statements of income.

The following table presents a summary of the Corporation’s mortgage loans held for sale:

	March 31, 2016		December 31, 2015
	(in thousands)
Cost	$	19,187	$	16,584
Fair value	19,719		16,886

During the three months ended March 31, 2016 and 2015, the Corporation recorded gains related to changes in fair values of mortgage loans held for sale of $230,000 and $261,000, respectively.

Balance Sheet Offsetting

Certain financial assets and liabilities may be eligible for offset on the consolidated balance sheets because they are subject to master netting arrangements or similar agreements. The Corporation elects to not offset assets and liabilities subject to such arrangements on the consolidated financial statements.

The Corporation is a party to interest rate swap transactions with financial institution counterparties and customers, disclosed in detail above. Under these agreements, the Corporation has the right to net-settle multiple contracts with the same counterparty in the event of default on, or termination of, any one contract. Cash collateral is posted by the party with a net liability position or the right to reclaim cash collateral exists in a net asset position in accordance with contract thresholds and can be used to settle the fair value of the interest rate swap agreements in the event of default.

The Corporation is also a party to foreign currency exchange contracts with financial institution counterparties, under which the Corporation has the right to net-settle multiple contracts with the same counterparty in the event of default on, or termination of, any one contract. As with interest rate swap contracts, cash collateral is posted by the party with a net liability position or the right to reclaim cash collateral exists in a net asset position in accordance with contract thresholds and can be used to settle the fair value of the foreign currency exchange contracts in the event of default.

The Corporation also enters into agreements with customers in which it sells securities subject to an obligation to repurchase the same or similar securities, referred to as repurchase agreements. Under these agreements, the Corporation may transfer legal control over the assets but still maintain effective control through agreements that both entitle and obligate the Corporation to repurchase the assets. Therefore, repurchase agreements are reported as secured borrowings, classified in short-term borrowings on the consolidated balance sheets, while the securities underlying the repurchase agreements remain classified with investment securities on the consolidated balance sheets. The Corporation has no intention of setting off these amounts. Therefore, these repurchase agreements are not eligible for offset.

27

The following table presents the Corporation's financial instruments that are eligible for offset, and the effects of offsetting, on the consolidated balance sheets:

	Gross Amounts		Gross Amounts Not Offset
	Recognized		on the Consolidated

Foreign exchange derivative liabilities with correspondent banks	147		(147		)	—			—
Total	$	33,117	$	(202	)	$	(31,130	)	$	1,785

(1) For derivative assets, amounts represent any derivative liability fair values that could be offset in the event of counterparty or customer default. For derivative liabilities, amounts represent any derivative asset fair values that could be offset in the event of counterparty or customer default.

(2) Amounts represent cash collateral posted or the right to reclaim cash collateral on interest rate swap transactions with financial institution counterparties and on foreign exchange derivative transactions with correspondent banks.

NOTE 10 – Commitments and Contingencies

Commitments

The Corporation is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers.

Those financial instruments include commitments to extend credit and letters of credit, which involve, to varying degrees, elements of credit risk and interest rate risk in excess of the amounts recognized on the Corporation’s consolidated balance sheets. Exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit and letters of credit is represented by the outstanding amount of those instruments.

The outstanding amounts of commitments to extend credit and letters of credit as of the dates indicated were as follows:

	March 31, 2016		December 31, 2015
	(in thousands)
Commitments to extend credit	$	5,932,144	$	5,784,138
Standby letters of credit	369,932		374,729
Commercial letters of credit	37,596		39,529

The Corporation records a reserve for unfunded lending commitments, which represents management’s estimate of losses associated with unused commitments to extend credit. See Note 5, "Loans and Allowance for Credit Losses," for additional details.

28

Residential Lending

Residential mortgages originated and sold by the Corporation consist primarily of conforming, prime loans sold to government sponsored agencies, such as the Federal National Mortgage Association ("Fannie Mae") and the Federal Home Loan Mortgage Corporation ("Freddie Mac"). The Corporation also sells certain prime loans it originates to non-government sponsored agency investors.

The Corporation provides customary representations and warranties to government sponsored entities and investors that specify, among other things, that the loans have been underwritten to the standards established by the government sponsored entity or investor. The Corporation may be required to repurchase a loan, or reimburse the government sponsored entity or investor for a credit loss incurred on a loan, if it is determined that the representations and warranties have not been met. Such repurchases or reimbursements generally result from an underwriting or documentation deficiency. As of both March 31, 2016 and December 31, 2015, total outstanding repurchase requests totaled approximately $543,000.

From 2000 to 2011, the Corporation sold loans to the Federal Home Loan Bank of Pittsburgh under its Mortgage Partnership Finance Program ("MPF Program"). The Corporation provided a "credit enhancement" for residential mortgage loans sold under the MPF Program whereby it would assume credit losses in excess of a defined "First Loss Account," or "FLA" balance, up to specified amounts. The FLA is funded by the Federal Home Loan Bank of Pittsburgh based on a percentage of the outstanding principal balance of loans sold. As of March 31, 2016, the unpaid principal balance of loans sold under the MPF Program was approximately $120 million. As of March 31, 2016 and December 31, 2015, the reserve for estimated credit losses related to loans sold under the MPF Program was $2.0 million and $1.8 million, respectively. Required reserves are calculated based on delinquency status and estimated loss rates established through the Corporation's existing allowance for credit losses methodology for residential mortgage loans.

As of March 31, 2016 and December 31, 2015, the total reserve for losses on residential mortgage loans sold was $2.7 million and $2.6 million, respectively, including both reserves for credit losses under the MPF Program and reserves for representation and warranty exposures. Management believes that the reserves recorded as of March 31, 2016 are adequate. However, declines in collateral values, the identification of additional loans to be repurchased, or a deterioration in the credit quality of loans sold under the MPF Program could necessitate additional reserves, established through charges to earnings, in the future.

Legal Proceedings

The Corporation and its subsidiaries are involved in various legal proceedings in the ordinary course of business of the Corporation. The Corporation periodically evaluates the possible impact of pending litigation matters based on, among other factors, the advice of counsel, available insurance coverage and recorded liabilities and reserves for probable legal liabilities and costs. In addition, from time to time, the Corporation is the subject of investigations or other forms of regulatory or governmental inquiry covering a range of possible issues and, in some cases, these may be part of similar reviews of the specified activities of other industry participants. These inquiries could lead to administrative, civil or criminal proceedings, and could possibly result in fines, penalties, restitution or the need to alter the Corporation’s business practices, and cause the Corporation to incur additional costs. The Corporation’s practice is to cooperate fully with regulatory and governmental investigations.

As of the date of this report, the Corporation believes that any liabilities, individually or in the aggregate, which may result from the final outcomes of pending proceedings will not have a material adverse effect on the financial condition of the Corporation. However, legal proceedings are often unpredictable, and it is possible that the ultimate resolution of any such matters, if unfavorable, may be material to the Corporation’s results of operations for any particular period, depending, in part, upon the size of the loss or liability imposed and the operating results for the applicable period.

BSA/AML Enforcement Orders

The Corporation and each of its bank subsidiaries are subject to regulatory enforcement orders issued during 2014 and 2015 by their respective federal and state bank regulatory agencies relating to identified deficiencies in the Corporation’s centralized Bank Secrecy Act and anti-money laundering compliance program (the "BSA/AML Compliance Program"), which was designed to comply with the requirements of the Bank Secrecy Act, the USA Patriot Act of 2001 and related anti-money laundering regulations (collectively, the "BSA/AML Requirements"). The regulatory enforcement orders, which are in the form of consent orders or orders to cease and desist issued upon consent ("Consent Orders"), generally require, among other things, that the Corporation and its bank subsidiaries undertake a number of required actions to strengthen and enhance the BSA/AML Compliance Program, and, in some cases, conduct retrospective reviews of past account activity and transactions, as well as certain reports filed in accordance with the BSA/AML Requirements, to determine whether suspicious activity and certain transactions in currency were

29

properly identified and reported in accordance with the BSA/AML Requirements. In addition to requiring strengthening and enhancement of the BSA/AML Compliance Program, while the Consent Orders remain in effect, the Corporation is subject to certain restrictions on expansion activities of the Corporation and its bank subsidiaries. Further, any failure to comply with the requirements of any of the Consent Orders involving the Corporation or its bank subsidiaries could result in further enforcement actions, the imposition of material restrictions on the activities of the Corporation or its bank subsidiaries, or the assessment of fines or penalties.

Fair Lending Investigation

During the second quarter of 2015, Fulton Bank, N.A. (the "Bank"), the Corporation’s largest bank subsidiary, received a letter from the U.S. Department of Justice (the "Department") indicating that the Department had initiated an investigation regarding potential violations of fair lending laws by the Bank in certain of its geographies. The Bank is cooperating with the Department and responding to the Department’s requests for information. Although the Corporation is not able to predict the outcome of the Department’s investigation, it could result in legal proceedings the resolution of which could potentially involve a settlement, fines or other remedial actions.

Agostino, et al. Litigation

Fulton Bank, N.A. (the "Bank"), the Corporation’s largest bank subsidiary, and two unrelated, third-party defendants, Ameriprise Financial Services, Inc. and Riverview Bank, have been named as defendants in a lawsuit brought on behalf of a group of 58 plaintiffs filed on March 31, 2016 in the Court of Common Pleas for Dauphin County, Pennsylvania (Agostino, et al. v. Ameriprise Financial Services, Inc., et al., No. 2016-CV-2048-CV). The plaintiffs in this action, who are individuals, trustees of certain irrevocable trusts or the executors of the estates of deceased individuals, were clients of Jeffrey M. Mottern, a now deceased attorney, who is alleged to have operated a Ponzi scheme which defrauded the plaintiffs over a period of years through the sale of fictitious, high-yielding investments or by otherwise misappropriating funds entrusted to Mr. Mottern. Mr. Mottern is alleged to have used the proceeds of these activities to engage in speculative securities trading, which incurred significant losses, and for Mr. Mottern’s personal expenses. The allegations against the Bank relate to a commercial checking account at the Bank maintained by Mr. Mottern in connection with Mr. Mottern’s law practice. The lawsuit alleges that the Bank is liable to the plaintiffs for failing to properly monitor Mr. Mottern’s checking account and detect Mr. Mottern’s fraudulent activity, and specifically alleges that the Bank aided and abetted Mr. Mottern’s: (1) fraud; (2) breach of fiduciary duty; (3) violations of the Pennsylvania Unfair Trade Practices and Consumer Protection Law; and (4) conversion. Similar claims have been asserted against Ameriprise Financial Services, Inc. and Riverview Bank, which allegedly maintained a personal brokerage account and a trust account for client or other third-party funds, respectively, for Mr. Mottern. The lawsuit seeks damages from the defendants, including the Bank, alleged to be in excess of $11.3 million, treble damages and attorneys’ fees with respect to alleged violations of the Pennsylvania Unfair Trade Practices and Consumer Protection Law, punitive damages, plus interest and costs. On April 29, 2016, the Bank filed a Notice of Removal to remove this lawsuit to the United States District Court for the Middle District of Pennsylvania.

NOTE 11 – Fair Value Measurements

FASB ASC Topic 820 establishes a fair value hierarchy for the inputs to valuation techniques used to measure assets and liabilities at fair value using the following three categories (from highest to lowest priority):

• Level 1 – Inputs that represent quoted prices for identical instruments in active markets.

• Level 2 – Inputs that represent quoted prices for similar instruments in active markets, or quoted prices for identical instruments in non-active markets. Also includes valuation techniques whose inputs are derived principally from observable market data other than quoted prices, such as interest rates or other market-corroborated means.

• Level 3 – Inputs that are largely unobservable, as little or no market data exists for the instrument being valued.

The Corporation has categorized all assets and liabilities measured at fair value on both a recurring and nonrecurring basis into the above three levels.

30

The following tables present summaries of the Corporation’s assets and liabilities measured at fair value on a recurring basis and reported on the consolidated balance sheets:

The valuation techniques used to measure fair value for the items in the preceding tables are as follows:

• Mortgage loans held for sale – This category consists of mortgage loans held for sale that the Corporation has elected to measure at fair value. Fair values as of March 31, 2016 and December 31, 2015 were measured based on the price that secondary market investors were offering for loans with similar characteristics. See Note 9, "Derivative Financial Instruments" for details related to the Corporation’s election to measure assets and liabilities at fair value.

• Available for sale investment securities – Included in this asset category are both equity and debt securities. Level 2 available for sale debt securities are valued by a third-party pricing service commonly used in the banking industry. The pricing service uses pricing models that vary based on asset class and incorporate available market information, including quoted prices of investment securities with similar characteristics. Because many fixed income securities do not trade on a daily basis, pricing models use available information, as applicable, through processes such as benchmark yield curves, benchmarking of like securities, sector groupings, and matrix pricing.

Standard market inputs include: benchmark yields, reported trades, broker/dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers and reference data, including market research publications. For certain security types, additional inputs may be used, or some of the standard market inputs may not be applicable.

31

Management tests the values provided by the pricing service by obtaining securities prices from an alternative third-party source and comparing the results. This test is done for approximately 80% of the securities valued by the pricing service. Generally, differences by security in excess of 5% are researched to reconcile the difference.

• Equity securities – Equity securities consist of common stocks of financial institutions ($18.2 million at March 31, 2016 and $20.6 million at December 31, 2015) and other equity investments ($892,000 at March 31, 2016 and $914,000 at December 31, 2015). These Level 1 investments are measured at fair value based on quoted prices for identical securities in active markets.

• U.S. Government securities/U.S. Government sponsored agency securities/State and municipal securities/Collateralized mortgage obligations/Mortgage-backed securities – These debt securities are classified as Level 2 investments. Fair values are determined by a third-party pricing service, as detailed above.

• Corporate debt securities – This category consists of subordinated debt issued by financial institutions ($49.3 million at March 31, 2016 and $53.1 million at December 31, 2015), single-issuer trust preferred securities issued by financial institutions ($35.9 million at March 31, 2016 and $39.1 million at December 31, 2015), pooled trust preferred securities issued by financial institutions ($706,000 at both March 31, 2016 and December 31, 2015) and other corporate debt issued by non-financial institutions ($4.0 million at both March 31, 2016 and December 31, 2015).

Level 2 investments include the Corporation’s holdings of subordinated debt, other corporate debt issued by non-financial institutions and $33.5 million and $36.5 million of single-issuer trust preferred securities held at March 31, 2016 and December 31, 2015, respectively. The fair values for these corporate debt securities are determined by a third-party pricing service, as detailed above.

Level 3 investments include the Corporation’s investments in pooled trust preferred securities ($706,000 at both March 31, 2016 and December 31, 2015) and certain single-issuer trust preferred securities ($2.4 million at March 31, 2016 and $2.6 million at December 31, 2015). The fair values of these securities were determined based on quotes provided by third-party brokers who determined fair values based predominantly on internal valuation models which were not indicative prices or binding offers. The Corporation’s third-party pricing service cannot derive fair values for these securities primarily due to inactive markets for similar investments. Level 3 values are tested by management primarily through trend analysis, by comparing current values to those reported at the end of the preceding calendar quarter, and determining if they are reasonable based on price and spread movements for this asset class.

• Auction rate securities – Due to their illiquidity, ARCs are classified as Level 3 investments and are valued through the use of an expected cash flows model prepared by a third-party valuation expert. The assumptions used in preparing the expected cash flows model include estimates for coupon rates, time to maturity and market rates of return. The most significant unobservable input to the expected cash flows model is an assumed return to market liquidity sometime in the next five years. If the assumed return to market liquidity was lengthened beyond the next five years, this would result in a decrease in the fair value of these ARCs. The Corporation believes that the trusts underlying the ARCs will self-liquidate as student loans are repaid. Level 3 fair values are tested by management through the performance of a trend analysis of the market price and discount rate. Changes in the price and discount rates are compared to changes in market data, including bond ratings, parity ratios, balances and delinquency levels.

Other assets – Included in this category are the following:

• Level 1 assets include mutual funds that are held in trust for employee deferred compensation plans ($15.7 million at March 31, 2016 and $15.6 million at December 31, 2015) and the fair value of foreign currency exchange contracts ($1.0 million at March 31, 2016 and $547,000 at December 31, 2015). The mutual funds and foreign exchange prices used to measure these items at fair value are based on quoted prices for identical instruments in active markets.

• Level 2 assets include the fair value of mortgage banking derivatives in the form of interest rate locks and forward commitments with secondary market investors ($2.5 million at March 31, 2016 and $1.5 million at December 31, 2015) and the fair value of interest rate swaps ($62.4 million at March 31, 2016 and $33.0 million at December 31, 2015). The fair values of the Corporation’s interest rate locks, forward commitments and interest rate swaps represent the amounts that would be required to settle the derivative financial instruments at the balance sheet date. See Note 9, "Derivative Financial Instruments," for additional information.

32

Other liabilities – Included in this category are the following:

• Level 1 liabilities include employee deferred compensation liabilities which represent amounts due to employees under deferred compensation plans ($15.7 million at March 31, 2016 and $15.6 million at December 31, 2015) and the fair value of foreign currency exchange contracts ($722,000 at March 31, 2016 and $331,000 at December 31, 2015). The fair value of these liabilities are determined in the same manner as the related assets, as described under the heading "Other assets" above.

• Level 2 liabilities include the fair value of mortgage banking derivatives in the form of interest rate locks and forward commitments with secondary market investors ($925,000 at March 31, 2016 and $40,000 at December 31, 2015) and the fair value of interest rate swaps ($62.4 million at March 31, 2016 and $33.0 million at December 31, 2015). The fair values of these liabilities are determined in the same manner as the related assets, as described under the heading "Other assets" above.

Certain financial assets are not measured at fair value on an ongoing basis, but are subject to fair value measurement in certain circumstances, such as upon their acquisition or when there is evidence of impairment. The following table presents the Corporation’s financial assets measured at fair value on a nonrecurring basis and reported on the Corporation’s consolidated balance sheets:

	March 31, 2016
	Level 1		Level 2		Level 3		Total
	(in thousands)
Net loans	$	—	$	—	$	131,875	$	131,875
Other financial assets	—		—		51,141		51,141

Other financial assets	—		—		52,043		52,043
Total assets	$	—	$	—	$	190,534	$	190,534

The valuation techniques used to measure fair value for the items in the table above are as follows:

• Net loans – This category consists of loans that were evaluated for impairment under FASB ASC Section 310-10-35 and have been classified as Level 3 assets. The amount shown is the balance of impaired loans, net of the related allowance for loan losses. See Note 5, "Loans and Allowance for Credit Losses," for additional details.

• Other financial assets – This category includes OREO ($10.9 million at March 31, 2016 and $11.1 million at December 31, 2015) and MSRs ($40.2 million at March 31, 2016 and $40.9 million at December 31, 2015), both classified as Level 3 assets.

Fair values for OREO were based on estimated selling prices less estimated selling costs for similar assets in active markets.

MSRs are initially recorded at fair value upon the sale of residential mortgage loans to secondary market investors. MSRs are amortized as a reduction to servicing income over the estimated lives of the underlying loans. MSRs are stratified and evaluated for impairment by comparing each stratum's carrying amount to its estimated fair value. Fair values are determined at the end of each quarter through a discounted cash flows valuation performed by a third-party valuation expert. Significant inputs to the valuation included expected net servicing income, the discount rate and the expected life of the underlying loans. Expected life is based on the contractual terms of the loans, as adjusted for prepayment projections. The weighted average annual constant prepayment rate and the weighted average discount rate used in the March 31, 2016 valuation were 12.5% and 9.6%, respectively. Management tests the reasonableness of the significant inputs to the third-party valuation in comparison to market data.

As required by FASB ASC Section 825-10-50, the following table details the book values and estimated fair values of the Corporation’s financial instruments as of March 31, 2016 and December 31, 2015. In addition, a general description of the methods and assumptions used to estimate such fair values is also provided.

(1) These financial instruments, or certain financial instruments in these categories, are measured at fair value on the Corporation’s consolidated balance sheets. Descriptions of the fair value determinations for these financial instruments are disclosed above.

Fair values of financial instruments are significantly affected by the assumptions used, principally the timing of future cash flows and discount rates. Because assumptions are inherently subjective in nature, the estimated fair values cannot be substantiated by comparison to independent market quotes and, in many cases, the estimated fair values could not necessarily be realized in an immediate sale or settlement of the instrument. The aggregate fair value amounts presented do not necessarily represent management’s estimate of the underlying value of the Corporation.

For short-term financial instruments, defined as those with remaining maturities of 90 days or less, and excluding those recorded at fair value on the Corporation’s consolidated balance sheets, book value was considered to be a reasonable estimate of fair value.

The following instruments are predominantly short-term:

Assets	Liabilities
Cash and due from banks	Demand and savings deposits
Interest-bearing deposits with other banks	Short-term borrowings
Accrued interest receivable	Accrued interest payable

Federal Reserve Bank and Federal Home Loan Bank ("FHLB") stock represent restricted investments and are carried at cost on the consolidated balance sheets.

Fair values for loans and time deposits were estimated by discounting future cash flows using the current rates at which similar loans would be made to borrowers and similar deposits would be issued to customers for the same remaining maturities. Fair values estimated in this manner do not fully incorporate an exit price approach to fair value, as defined in FASB ASC Topic 820.

The fair values of FHLB advances and long-term debt were estimated by discounting the remaining contractual cash flows using a rate at which the Corporation could issue debt with similar remaining maturities as of the balance sheet date. These borrowings would be categorized in Level 2 liabilities under FASB ASC Topic 820.

Many factors could affect future financial results including, without limitation:

• the impact of adverse conditions in the economy and capital markets on the performance of the Corporation’s loan portfolio and demand for the Corporation’s products and services;

• increases in non-performing assets, which may require the Corporation to increase the allowance for credit losses, charge off loans and incur elevated collection and carrying costs related to such non-performing assets;

• investment securities gains and losses, including other-than-temporary declines in the value of securities which may result in charges to earnings;

• the effects of market interest rates, and the relative balances of rate-sensitive assets to rate-sensitive liabilities, on net interest margin and net interest income;

• the effects of changes in interest rates on demand for the Corporation’s products and services;

• the effects of changes in interest rates or disruptions in liquidity markets on the Corporation’s sources of funding;

• the Corporation’s ability to manage liquidity, both at the holding company level and at its bank subsidiaries;

• the impact of increased regulatory scrutiny of the banking industry;

• the effects of the increasing amounts of time and expense associated with regulatory compliance and risk management;

• the potential for negative consequences from regulatory violations, including potential supervisory actions and the assessment of fines and penalties;

• the additional time, expense and investment required to comply with, and the restrictions on potential growth and investment activities resulting from, the existing enforcement orders applicable to the Corporation and its bank subsidiaries by federal and state bank regulatory agencies requiring improvement in compliance functions and other remedial actions, or any future enforcement orders;

• the Corporation’s ability to manage the uncertainty associated with the delay in implementing many of the regulations mandated by the Dodd-Frank Act;

• the effects of negative publicity on the Corporation’s reputation;

• the effects of adverse outcomes in litigation and governmental or administrative proceedings;

• the Corporation’s ability to successfully transform its business model;

• the Corporation’s ability to achieve its growth plans;

• the effects of competition on deposit rates and growth, loan rates and growth and net interest margin;

• the Corporation’s ability to manage the level of non-interest expenses, including salaries and employee benefits expenses, operating risk losses and goodwill impairment;

• the impact of operational risks, including the risk of human error, inadequate or failed internal processes and systems, computer and telecommunications systems failures, faulty or incomplete data and an inadequate risk management framework;

• the impact of failures of third parties upon which the Corporation relies to perform in accordance with contractual arrangements;

• the failure or circumvention of the Corporation’s system of internal controls;

• the loss of, or failure to safeguard, confidential or proprietary information;

• the Corporation’s failure to identify and to address cyber-security risks;

36

• the Corporation’s ability to keep pace with technological changes;

• the Corporation’s ability to attract and retain talented personnel;

• capital and liquidity strategies, including the Corporation’s ability to comply with applicable capital and liquidity requirements, and the Corporation’s ability to generate capital internally or raise capital on favorable terms;

• the Corporation’s reliance on its subsidiaries for substantially all of its revenues and its ability to pay dividends or other distributions; and

• the effects of any downgrade in the Corporation’s credit ratings on its borrowing costs or access to capital markets.

RESULTS OF OPERATIONS

Overview and Outlook

Fulton Financial Corporation is a financial holding company comprised of six wholly owned banking subsidiaries which provide a full range of retail and commercial financial services in Pennsylvania, Delaware, Maryland, New Jersey and Virginia. The Corporation generates the majority of its revenue through net interest income, or the difference between interest earned on loans and investments and interest paid on deposits and borrowings. Growth in net interest income is dependent upon balance sheet growth and/or maintaining or increasing the net interest margin, which is net interest income (fully taxable-equivalent, or "FTE") as a percentage of average interest-earning assets. The Corporation also generates revenue through fees earned on the various services and products offered to its customers and through gains on sales of assets, such as loans, investments, or properties. Offsetting these revenue sources are provisions for credit losses on loans, non-interest expenses and income taxes.

The following table presents a summary of the Corporation’s earnings and selected performance ratios:

(2) Presented on an FTE basis, using a 35% federal tax rate and statutory interest expense disallowances. See also the “Net Interest Income” section of Management’s Discussion.

Net income for the three months ended March 31, 2016 decreased $1.8 million, or 4.4%, compared to the same period of 2015, mainly due to an increase in the provision for credit losses, a decrease in investment securities gains and an increase in non-interest expense, partially offset by an increase in net interest income.

Following is a summary of financial highlights for the three months ended March 31, 2016:

FTE Net Interest Income and Net Interest Margin - For the three months ended March 31, 2016, FTE net interest income increased $5.9 million, or 4.6%, in comparison to the same period in 2015. This increase was driven by growth in interest-earning assets, partially offset by a 4 basis point decrease in the net interest margin.

Average interest-earning assets increased $825.2 million, or 5.2%, in the first quarter of 2016 in comparison to the same period in 2015, mainly due to a $757.9 million, or 5.8%, increase in average loans and a $187.5 million, or 8.3%, increase in average investment securities, partially offset by a $115.5 million, or 24.4%, decrease in other interest-earning assets.

37

Average interest-bearing liabilities increased $494.6 million, or 4.4%, primarily due to a $524.3 million, or 5.4%, increase in interest-bearing deposits, and a $136.2 million, or 44.0%, increase in short-term borrowings, partially offset by $165.9 million, or 14.8%, decrease in FHLB advances and long-term debt. Additional funding to support the increase in interest-earning assets was provided by a $305.8 million, or 8.4%, increase in noninterest-bearing deposits.

Asset Quality - The Corporation recorded a $1.5 million provision for credit losses during the three months ended March 31, 2016, compared to a $3.7 million negative provision for the same period in 2015. The negative provision in 2015 was driven by an improvement in net charge-off levels, particularly among pooled impaired loans across all portfolio segments.

Annualized net charge-offs to average loans outstanding were 0.20% for the first quarter of 2016, compared to 0.08% for the first quarter of 2015. Non-performing assets decreased $15.4 million, or 9.4%, as of March 31, 2016 compared to March 31, 2015 and were 0.82% and 0.94% of total assets as of March 31, 2016 and March 31, 2015, respectively. The total delinquency rate was 1.44% as of March 31, 2016, compared to 1.76% as of March 31, 2015.

Non-interest Income - For the three months ended March 31, 2016, non-interest income, excluding investment securities gains, increased $1.6 million, or 3.9%, in comparison to the same periods in 2015. The increase was primarily a result of higher service charges on deposit accounts and other service charges and fees, partially offset by a decrease in mortgage sales gains.

Gains on sales of investment securities for the three months ended March 31, 2016 were $947,000 as compared to $4.1 million for the three months ended March 31, 2015.

Non-interest Expense - For the three months ended March 31, 2016, non-interest expense increased $1.9 million, or 1.6%, in comparison to the same period in 2015. The primary driver of the increase was a $4.4 million, or 6.7%, increase in salaries and employee benefits, partially offset by decreases in other expense categories, most notably occupancy.

2016 Outlook

The Corporation's outlook for 2016:

• annual mid- to high- single digit growth rate in average loans and deposits;

• net interest margin expected to be stable on an annual basis with modest quarterly volatility of plus or minus 0 to 3 basis points;

• provision for credit losses driven primarily by loan growth;

• annual mid- to high- single digit growth rate in non-interest income, excluding the impact of securities gains;

• annual low- to mid- single digit growth rate in non-interest expense (excluding loss on redemption of Trust Preferred Securities (TruPS) incurred in the third quarter of 2015); and

• focus on utilizing capital to support growth and provide appropriate returns to shareholders.

Supplemental Reporting of Non-GAAP Based Financial Measures

This Quarterly Report on Form 10-Q contains supplemental financial information, as detailed below, which has been derived by methods other than GAAP. The Corporation has presented these non-GAAP financial measures because it believes that these measures provide useful and comparative information to assess trends in the Corporation's results of operations. Presentation of these non-GAAP financial measures is consistent with how the Corporation evaluates its performance internally, and these non-GAAP financial measures are frequently used by securities analysts, investors and other interested parties in the evaluation of companies in the Corporation's industry. Management believes that these non-GAAP financial measures, in addition to GAAP measures, are also useful to investors to evaluate the Corporation's results. Investors should recognize that the Corporation's presentation of these non-GAAP financial measures might not be comparable to similarly-titled measures of other companies. These non-GAAP financial measures should not be considered a substitute for GAAP basis measures, and the Corporation strongly encourages a review of its consolidated financial statements in their entirety. Following are reconciliations of these non-GAAP financial measures to the most directly comparable GAAP measure as of and for the quarter ended March 31:

Quarter Ended March 31, 2016 compared to the Quarter Ended March 31, 2015

Net Interest Income

FTE net interest income increased $5.9 million, to $134.0 million, in the first quarter of 2016, from $128.1 million in the first quarter of 2015. This increase was primarily due to an $825.2 million, or 5.2%, increase in interest earning assets, partially offset by the impact of a 4 basis point, or 1.2%, decrease in the net interest margin, to 3.23% for the first quarter of 2016 from 3.27% for the first quarter of 2015. The following table provides a comparative average balance sheet and net interest income analysis for those periods. Interest income and yields are presented on an FTE basis, using a 35% federal tax rate and statutory interest expense disallowances. The discussion following this table is based on these FTE amounts.

Average loans increased $757.9 million, or 5.8%, compared to the first quarter of 2015, mainly in commercial loans, commercial mortgage, construction loans and leasing and other. The average yield on loans decreased 11 basis points, or 2.7%, to 4.00% in 2016 from 4.11% in 2015. The decrease in average yields on loans was attributable to repayments of higher-yielding loans, continued refinancing activity at lower rates, and new loan production at rates lower than the overall portfolio yield.

41

Average total interest-bearing liabilities increased $494.6 million, or 4.4%, compared to the first quarter of 2015. Interest expense decreased $1.9 million, or 8.7%, to $20.3 million in the first quarter of 2016 as a result of a change in the mix from higher cost long-term debt to lower-cost deposits. Average deposits and average interest rates, by type, are summarized in the following table:

	Three months ended March 31								Increase (Decrease) in Balance
	2016				2015

Total deposits	$	14,206,717	0.30	%	$	13,376,617	0.30	%	$	830,100		6.2	%

The $1.0 billion, or 9.9%, increase in total demand and savings accounts was primarily due to a $465.7 million, or 9.7%, increase in personal account balances, a $363.6 million, or 10.0%, increase in business account balances and a $195.6 million, or 10.7%, increase in municipal account balances. The average cost of total deposits remained unchanged in the first quarter of 2016 compared to the first quarter of 2015 as a result of an increase in noninterest-bearing deposits, which offset the impact of higher average rates on interest-bearing deposits.

N/M - Not meaningful

(1) Represents FHLB advances with an original maturity term of less than one year.

Total short-term borrowings increased $136.2 million, or 44.0%, as a result of increases in federal funds purchased. The increase generally reflects a shift from long-term to short-term wholesale funding. Average other long-term debt decreased $165.9 million, or 14.8%. This decrease was primarily due to of the maturity of $100.0 million of subordinated debt in April 2015 and a $61.3 million decrease in FHLB advances. In addition, during 2015, the Corporation redeemed $150.0 million of TruPS with the proceeds from the issuance of $150.0 million of lower-cost subordinated debt. These transactions contributed to a 52 basis point decrease in the cost of other long-term debt. The average cost of total borrowings decreased 75 basis points, or 21.6%, primarily due to the Corporation's continuing efforts to lengthen maturities and lock in longer-term rates.

Provision for Credit Losses

The provision for credit losses was $1.5 million for the first quarter of 2016, an increase of $5.2 million from the negative provision in the first quarter of 2015. The negative provision for the three months ended March 31, 2015 was driven by an improvement in net charge-off levels, particularly among pooled impaired loans across all portfolio segments.

42

The provision for credit losses is recognized as an expense in the consolidated statements of income and is the amount necessary to adjust the allowance for credit losses to its appropriate balance, as determined through the Corporation's allowance methodology. The Corporation determines the appropriate level of the allowance for credit losses based on many quantitative and qualitative factors, including, but not limited to: the size and composition of the loan portfolio, changes in risk ratings, changes in collateral values, delinquency levels, historical losses and economic conditions. See the "Financial Condition" section of Management's Discussion under the heading "Provision for Credit Losses and Allowance for Credit Losses" for details related to the Corporation's allowance and provision for credit losses.

Non-Interest Income

Total	$	43,137	$	44,737	$	(1,600	)	(3.6	)%

Excluding gains on sales of investment securities, non-interest income increased $1.6 million, or 3.9%.Other service charges and fees grew $1.4 million, or 14.8%, driven mainly by a $631,000 increase in commercial interest rate swap fees, as new loan volumes increased in comparison to the first quarter of 2015, and by a $505,000 increase in merchant fee income related to higher transaction volumes in the first quarter of 2016.Service charges on deposits increased $989,000, or 8.5%, across all categories.

Gains on sales of mortgage loans decreased $863,000, or 24.4%, when compared to the first quarter of 2015, the net effect of a 34.7% decrease in volumes and a 15.6% increase in spreads. Mortgage servicing income increased $205,000, or 17.7%, due to a decrease in amortization of MSRs, as prepayments were lower when compared to the first quarter of 2015.

Gains on sales of investment securities decreased $3.2 million from the first quarter of 2015, which included gains from the sales of two pooled trust preferred debt securities in 2015. See Note 4, "Investment Securities," in the Notes to Consolidated Financial Statements for additional details.

Total	$	120,413	$	118,478	$	1,935		1.6	%

The $4.4 million, or 6.7%, increase in salaries and employee benefits primarily resulted from a $4.2 million, or 7.9%, increase in salaries, resulting primarily from higher average salaries per full-time equivalent (FTE) employee, normal merit increases, an increase in incentive compensation, and an additional day of expense in the first quarter of 2016. Benefits expenses were largely unchanged.

Net occupancy expense decreased $1.5 million, or 10.8%, as a result of milder winter conditions in 2016 driving down snow removal and utilities costs when compared to the first quarter of 2015. In addition, 2015 included $600,000 of accelerated depreciation related to consolidated branches.

Outside services include fees paid to consultants and expenses for contracted or outsourced services. Consulting expenses can fluctuate based on the timing and need for such services. The $306,000, or 5.3%, increase in expense in comparison to the first quarter of 2015 was largely due to the timing of certain expenses related to the Corporation’s BSA/AML Compliance Program remediation efforts.

The $1.2 million, or 15.3%, combined increase in data processing and software resulted from higher transaction volumes and contractual increases related to core processing systems, and amortization of capitalized software investments.

Equipment expense decreased $587,000, or 14.8%, primarily due to lower depreciation expense when compared to the first quarter of 2015 as certain assets became fully depreciated.

The $538,000, or 18.7%, decrease in professional fees was driven by lower costs for legal services resulting from both the timing and the need for such services.

Other real estate owned and repossession expense decreased $724,000, or 53.2%, when compared to the first quarter of 2015. This decrease was due to a $473,000 decrease in net losses on the sales of other real estate properties due to fewer transactions, and a $212,000 decrease in repossession expense due to lower activity.

The $750,000 decrease in the other category was mainly due to lower state taxes as liabilities were adjusted to reflect current expectations regarding state tax exposures.

44

Income Taxes

Income tax expense for the first quarter of 2016 was $12.0 million, a $1.5 million, or 11.2%, decrease from $13.5 million for the first quarter of 2015.

The Corporation’s effective tax rate was 23.9% in the first quarter of 2016, as compared to 25.2% in the first quarter of 2015. The effective tax rate is generally lower than the federal statutory rate of 35% due to investments in tax-free municipal securities and credits earned from investments in partnerships that generate tax credits under various federal programs. The decrease in the effective rate from the first quarter of 2015 was driven by lower pre-tax earnings and higher low-income housing tax credits.

Total Liabilities and Shareholders’ Equity	$	18,122,254	$	17,914,718	$	207,536		1.2	%

The $115.5 million, or 39.5%, increase in other interest-earning assets resulted from higher balances of excess cash on deposit with the Federal Reserve Bank due to a higher net liquidity position, generally resulting from deposit growth exceeding loan growth.

The $35.5 million, or 6.0%, increase in other assets and the $32.8 million, or 11.2%, increase in other liabilities were driven by higher fair values for derivative financial instruments. See Note 9, "Derivative Financial Instruments," in the Notes to Consolidated Financial Statements for additional details.

The Corporation does not have a significant concentration of credit risk with any single borrower, industry or geographical location. Approximately $6.4 billion, or 45.9%, of the loan portfolio was in commercial mortgage and construction loans as of March 31, 2016. The Corporation's maximum total lending commitment to an individual borrower was $50.0 million as of March 31, 2016. In addition to its policy of limiting the maximum total lending commitment to any individual borrower to $50.0 million, the Corporation has established lower total lending limits for certain types of lending commitments, and lower total lending limits based on the Corporation's internal risk rating of an individual borrower at the time the lending commitment is approved. As of March 31, 2016, the Corporation had 112 relationships with total borrowing commitments between $20.0 million and $50.0 million.

Commercial mortgage loans increased $95.8 million, or 1.8%, in comparison to December 31, 2015 across all of the Corporation's geographical markets. Commercial loans decreased $53.6 million, or 1.3%, primarily in the New Jersey ($31.2 million, or 5.5%), Pennsylvania ($19.0 million, or 0.6%), Virginia ($8.8 million, or 6.3%) and Delaware ($4.2 million, or 3.3%) markets, partially offset by an increase in the Maryland market ($9.5 million, or 2.9%).

Total	$	253,954	$	249,049

Total shared national credits increased $4.9 million, or 2.0%, in comparison to December 31, 2015. The Corporation's shared national credits are to borrowers located in its geographical markets, and the increase was due to normal lending activities consistent with the Corporation's underwriting policies. As of March 31, 2016, none of the shared national credits were past due compared to one credit totaling $1.1 million, or 0.4%, of the total balance that was past due as of December 31, 2015.

Construction loans include loans to commercial borrowers secured by commercial real estate, loans to commercial borrowers secured by residential real estate, and other construction loans, which represent loans to individuals secured by residential real estate.

Allowance for credit losses	$	166,065		$	171,412
Allowance for credit losses to loans outstanding	1.20		%	1.24		%

The provision for credit losses for the three months endedMarch 31, 2016 was $1.5 million, an increase of $5.2 million in comparison to the same period in 2015. The increase in the provision for credit losses was due to a negative provision for the three months ended March 31, 2015 which was driven by an improvement in net charge-off levels, particularly among pooled impaired loans across all portfolio segments.

48

Net charge-offs increased $4.3 million, or 167.3%, to $6.9 million for the first quarter of 2016, compared to $2.6 million for the first quarter of 2015. The increase in net charge-offs was primarily due to a $2.8 million increase in commercial loan net charge-offs and a $1.1 million increase in real estate construction net charge-offs as a result of lower recoveries compared to the same period in the prior year. Of the $6.9 million of net charge-offs recorded in the first quarter of 2016, the majority were for loans originated in Pennsylvania ($5.5 million, or 80.0%) and New Jersey ($1.2 million, or 17.2%).

The Corporation's ability to identify potential problem loans in a timely manner is important to maintaining an adequate allowance for credit losses. For commercial loans, commercial mortgages and construction loans to commercial borrowers, an internal risk rating process is used to monitor credit quality. The evaluation of credit risk for residential mortgages, home equity loans, construction loans to individuals, consumer loans and lease receivables is based on payment history, through the monitoring of delinquency levels and trends. For a description of the Corporation's risk ratings, see Note 5, "Loans and Allowance for Credit Losses," in the Notes to Consolidated Financial Statements.

Noninterest-bearing demand deposits increased $186.7 million, or 4.7%, primarily as a result of increases in business account balances of $161.9 million, or 5.4%, and municipal account balances of $20.8 million, or 22.7%.

Interest-bearing demand accounts decreased $21.0 million, or 0.6%, primarily due to a $29.5 million, or 1.5%, decrease in personal account balances and a $3.6 million, or 1.2%, decrease in business account balances partially offset by a $12.1 million, or 1.0%, increase in municipal account balances. The $104.2 million, or 2.7%, increase in savings account balances was due to a $141.4 million, or 5.7%, increase in personal account balances partially offset by a decrease of $28.1 million, or 4.9%, in municipal account balances and a $9.2 million, or 1.2%, decrease in business account balances.

The $144.8 million, or 29.1%, decrease in total short-term borrowings reflects the use of a portion of the $272.0 million increase in deposits to repay short-term borrowings, as loan growth was lower.

Shareholders' Equity

Total shareholders’ equity increased $31.4 million, or 1.5%, during the first three months of 2016. The increase was due primarily to $38.3 million of net income and a $16.9 million increase in other comprehensive income, partially offset by $15.6 million of common stock dividends and $11.2 million in treasury stock purchases.

The Corporation and its subsidiary banks are subject to regulatory capital requirements administered by various banking regulators. Failure to meet minimum capital requirements could result in certain actions by regulators that could have a material effect on the Corporation’s financial statements. In July 2013, the Federal Reserve Board approved final rules (the "U.S. Basel III Capital Rules") establishing a new comprehensive capital framework for U.S. banking organizations and implementing the Basel Committee on Banking Supervision's December 2010 framework for strengthening international capital standards. The U.S. Basel III Capital Rules substantially revise the risk-based capital requirements applicable to bank holding companies and depository institutions.

The new minimum regulatory capital requirements established by the U.S. Basel III Capital Rules became effective for the Corporation on January 1, 2015, and will be fully phased in on January 1, 2019.

The U.S. Basel III Capital Rules require the Corporation and its bank subsidiaries to:

• Meet a new minimum Common Equity Tier 1 capital ratio of 4.50% of risk-weighted assets and a Tier 1 capital ratio of 6.00% of risk-weighted assets;

• Continue to require the current minimum Total capital ratio of 8.00% of risk-weighted assets and the minimum Tier 1 leverage capital ratio of 4.00% of average assets; and

• Comply with a revised definition of capital to improve the ability of regulatory capital instruments to absorb losses. Certain non-qualifying capital instruments, including cumulative preferred stock and TruPS, are being phased out as a component of Tier 1 capital for institutions of the Corporation's size.

When fully phased in on January 1, 2019, the Corporation and its bank subsidiaries will also be required to maintain a "capital conservation buffer" of 2.50% above the minimum risk-based capital requirements, which must be maintained to avoid restrictions on capital distributions and certain discretionary bonus payments.

The U.S. Basel III Capital Rules use a standardized approach for risk weightings that expands the risk-weightings for assets and off-balance sheet exposures from the previous 0%, 20%, 50% and 100% categories to a much larger and more risk-sensitive number of categories, depending on the nature of the assets and off-balance sheet exposures and resulting in higher risk weights for a variety of asset categories.

As of March 31, 2016, the Corporation and each of its bank subsidiaries met the minimum requirements of the U.S. Basel III Capital Rules, and each of the Corporation’s bank subsidiaries’ capital ratios exceeded the amounts required to be considered "well capitalized" as defined in the regulations. As of March 31, 2016, the Corporation's capital levels also met the fully-phased in minimum capitalrequirements, including the capital conservation buffers, as prescribed in the U.S. Basel III Capital Rules.

The following table summarizes the Corporation’s capital ratios in comparison to regulatory requirements:

	March 31, 2016		December 31, 2015		Regulatory Minimum for Capital Adequacy		Fully Phased-in, with Capital Conservation Buffers
Total Capital (to Risk-Weighted Assets)	13.1	%	13.2	%	8.0	%	10.5	%

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Market risk is the exposure to economic loss that arises from changes in the values of certain financial instruments. The types of market risk exposures generally faced by financial institutions include interest rate risk, equity market price risk, debt security market price risk, foreign currency price risk and commodity price risk. Due to the nature of its operations, foreign currency price risk and commodity price risk are not significant to the Corporation.

Interest Rate Risk, Asset/Liability Management and Liquidity

Interest rate risk creates exposure in two primary areas. First, changes in rates have an impact on the Corporation’s liquidity position and could affect its ability to meet obligations and continue to grow. Second, movements in interest rates can create fluctuations in the Corporation’s net interest income and changes in the economic value of its equity.

The Corporation employs various management techniques to minimize its exposure to interest rate risk. An Asset/Liability Management Committee (ALCO) is responsible for reviewing the interest rate sensitivity and liquidity positions of the Corporation, approving asset and liability management policies, and overseeing the formulation and implementation of strategies regarding balance sheet positions.

The Corporation uses two complementary methods to measure and manage interest rate risk. They are simulation of net interest income and estimates of economic value of equity. Using these measurements in tandem provides a reasonably comprehensive summary of the magnitude of the Corporation's interest rate risk, level of risk as time evolves, and exposure to changes in interest rates.

Simulation of net interest income is performed for the next 12-month period. A variety of interest rate scenarios are used to measure the effects of sudden and gradual movements upward and downward in the yield curve. These results are compared to the results obtained in a flat or unchanged interest rate scenario. Simulation of net interest income is used primarily to measure the Corporation’s short-term earnings exposure to rate movements. The Corporation’s policy limits the potential exposure of net interest income, in a non-parallel instantaneous shock, to 10% of the base case net interest income for a 100 basis point shock in interest rates, 15% for a 200 basis point shock and 20% for a 300 basis point shock. A "shock" is an immediate upward or downward movement of interest rates. The shocks do not take into account changes in customer behavior that could result in changes to mix and/or volumes in the balance sheet, nor do they take into account the potential effects of competition on the pricing of deposits and loans over the forward 12-month period.

Contractual maturities and repricing opportunities of loans are incorporated in the simulation model as are prepayment assumptions, maturity data and call options in the investment portfolio. Assumptions based on past experience are incorporated into the model for non-maturity deposit accounts. The assumptions used are inherently uncertain and, as a result, the model cannot precisely measure future net interest income or precisely predict the impact of fluctuations in market interest rates on net interest income. Actual results will differ from the model's simulated results due to timing, amount and frequency of interest rate changes as well as changes in market conditions and the application and timing of various management strategies.

The following table summarizes the expected impact of abrupt interest rate changes on net interest income as of March 31, 2016 (due to the current level of interest rates, the 200 and 300 basis point downward shock scenarios are not shown):

Rate Shock (1)	Annual change in net interest income	% Change in net interest income
+300 bp	+ $82.7 million	16.0%
+200 bp	+ $55.4 million	10.7%
+100 bp	+ $25.8 million	5.0%
–100 bp	– $14.2 million	– 2.7%

(1) These results include the effect of implicit and explicit interest rate floors that limit further reduction in interest rates.

Economic value of equity estimates the discounted present value of asset and liability cash flows. Discount rates are based upon market prices for like assets and liabilities. Abrupt changes or "shocks" in interest rates, both upward and downward, are used to determine the comparative effect of such interest rate movements relative to the unchanged environment. This measurement tool is used primarily to evaluate the longer-term repricing risks and options in the Corporation’s balance sheet. The Corporation's policy limits the economic value of equity that may be at risk, in a non-parallel instantaneous shock, to 10% of the base case economic value of equity for a 100 basis point shock in interest rates, 20% for a 200 basis point shock and 30% for a 300 basis

point shock. As of March 31, 2016, the Corporation was within economic value of equity policy limits for every 100 basis point shock.

Interest Rate Swaps

The Corporation enters into interest rate swaps with certain qualifying commercial loan customers to meet their interest rate risk management needs. The Corporation simultaneously enters into interest rate swaps with dealer counterparties, with identical notional amounts and terms. The net result of these interest rate swaps is that the customer pays a fixed rate of interest and the Corporation receives a floating rate. These interest rate swaps are derivative financial instruments that are recorded at their fair value in other assets and liabilities on the consolidated balance sheets. Changes in fair value during the period are recorded in other non-interest expense on the consolidated statements of income.

Liquidity

The Corporation must maintain a sufficient level of liquid assets to meet the cash needs of its customers, who, as depositors, may want to withdraw funds or who, as borrowers, need credit availability. Liquidity is provided on a continuous basis through scheduled and unscheduled principal and interest payments on investments and outstanding loans and through the availability of deposits and borrowings. The Corporation also maintains secondary sources that provide liquidity on a secured and unsecured basis to meet short-term and long-term needs.

The Corporation maintains liquidity sources in the form of demand and savings deposits, time deposits, repurchase agreements and short-term promissory notes. The Corporation can access additional liquidity from these sources, if necessary, by increasing the rates of interest paid on those accounts and borrowings. The positive impact to liquidity resulting from paying higher interest rates could have a detrimental impact on the net interest margin and net income if rates on interest-earning assets do not experience a proportionate increase. Borrowing availability with the FHLB and the Federal Reserve Bank, along with federal funds lines at various correspondent banks, provides the Corporation with additional liquidity.

Each of the Corporation’s subsidiary banks is a member of the FHLB and has access to FHLB overnight and term credit facilities.As of March 31, 2016, the Corporation had $684.7 million of short- and long-term advances outstanding from the FHLB with an additional borrowing capacity of approximately $2.7 billion under these facilities. Advances from the FHLB are secured by qualifying commercial real estate and residential mortgage loans, investments and other assets.

As of March 31, 2016, the Corporation had aggregate availability under federal funds lines of $1.2 billion with $32.6 million borrowed against that amount. A combination of commercial real estate loans, commercial loans and securities are pledged to the Federal Reserve Bank of Philadelphia to provide access to Federal Reserve Bank Discount Window borrowings. As of March 31, 2016, the Corporation had $1.2 billion of collateralized borrowing availability at the Discount Window, and no outstanding borrowings.

Liquidity must also be managed at the Fulton Financial Corporation parent company level. For safety and soundness reasons, banking regulations limit the amount of cash that can be transferred from subsidiary banks to the parent company in the form of loans and dividends. Generally, these limitations are based on the subsidiary banks’ regulatory capital levels and their net income. Management continues to monitor the liquidity and capital needs of the parent company and will implement appropriate strategies, as necessary, to remain adequately capitalized and to meet its cash needs.

The Corporation’s sources and uses of funds were discussed in general terms in the net interest income section of Management’s Discussion and Analysis. The consolidated statements of cash flows provide additional information. The Corporation’s operatingactivities during 2016 generated $34.1 million of cash, mainly due to net income. Cash used in investing activities was $169.7 million, due to net increases in loans and investment securities, partially offset by a decrease in short-term investments. Net cash provided by financing activities was $117.9 million due to increases in deposits, short-term borrowings and additions to long-term debt, partially offset by repayments of long-term debt, common stock, cash dividends and purchases of treasury stock.

Equity Market Price Risk

Equity market price risk is the risk that changes in the values of equity investments could have a material impact on the financial position or results of operations of the Corporation. As of March 31, 2016, equity investments consisted of $18.2 million of common stocks of publicly traded financial institutions and $892,000 of other equity investments.

The equity investments most susceptible to equity market price risk are the financial institutions stocks, which had a cost basis of approximately $13.4 million and a fair value of $18.2 million at March 31, 2016, including an investment in a single financial

55

institution with a cost basis of $7.4 million and a fair value of $9.1 million. The fair value of this investment accounted for 50.3% of the fair value of the common stocks of publicly traded financial institutions. No other investment in a single financial institution in the financial institutions stock portfolio exceeded 10% of the portfolio's fair value. In total, net unrealized gains in this portfolio were approximately $4.8 million as of March 31, 2016.

Management continuously monitors the fair value of its equity investments and evaluates current market conditions and operating results of the issuers. Periodic sale and purchase decisions are made based on this monitoring process. None of the Corporation’s equity securities are classified as trading.

In addition to its equity portfolio, investment management and trust services income may be impacted by fluctuations in the equity markets. A portion of this revenue is based on the value of the underlying investment portfolios, many of which include equity investments. If the values of those investment portfolios decrease, whether due to factors influencing U.S. or international securities markets in general or otherwise, the Corporation’s revenue would be negatively impacted. In addition, the Corporation’s ability to sell its brokerage services in the future will be dependent, in part, upon consumers’ level of confidence in financial markets.

Debt Security Market Price Risk

Debt security market price risk is the risk that changes in the values of debt securities, unrelated to interest rate changes, could have a material impact on the financial position or results of operations of the Corporation. The Corporation’s debt security investments consist primarily of U.S. government sponsored agency issued mortgage-backed securities and collateralized mortgage obligations, state and municipal securities, U.S. government debt securities, auction rate securities and corporate debt securities. All of the Corporation's investments in mortgage-backed securities and collateralized mortgage obligations have principal payments that are guaranteed by U.S. government sponsored agencies.

Municipal Securities

As of March 31, 2016, the Corporation owned $314.0 million of municipal securities issued by various municipalities. Ongoing uncertainty with respect to the financial strength of municipal bond insurers places much greater emphasis on the underlying strength of issuers. Continued pressure on local tax revenues of issuers due to adverse economic conditions could have an adverse impact on the underlying credit quality of issuers. The Corporation evaluates existing and potential holdings primarily based on the creditworthiness of the issuing municipality and then, to a lesser extent, on any underlying credit enhancement. Municipal securities can be supported by the general obligation of the issuing municipality, allowing the securities to be repaid by any means available to the issuing municipality. As of March 31, 2016, approximately 97% of municipal securities were supported by the general obligation of corresponding municipalities. Approximately 78% of these securities were school district issuances, which are also supported by the states of the issuing municipalities.

Auction Rate Certificates

As of March 31, 2016, the Corporation’s investments in student loan auction rate securities, also known as auction rate certificates (ARCs), had a cost basis of $106.9 million and a fair value of $97.3 million.

ARCs are long-term securities that were structured to allow their sale in periodic auctions, resulting in both the treatment of ARCs as short-term instruments in normal market conditions and fair values that could be derived based on periodic auction prices. However, beginning in 2008, market auctions for these securities began to fail due to an insufficient number of buyers, resulting in an illiquid market. Therefore, as of March 31, 2016, the fair values of the ARCs currently in the portfolio were derived using significant unobservable inputs based on an expected cash flows model which produced fair values that were materially different from those that would be expected from settlement of these investments in the current market. The expected cash flows model produced fair values which assumed a return to market liquidity sometime in the next five years. The Corporation believes that the trusts underlying the ARCs will self-liquidate as student loans are repaid.

The credit quality of the underlying debt associated with the ARCs is also a factor in the determination of their estimated fair value. As of March 31, 2016, all of the ARCs were rated above investment grade, with approximately $6 million, or 6%, "AAA" rated and $92 million, or 94%, "AA" rated. All of the loans underlying the ARCs have principal payments that are guaranteed by the federal government. At March 31, 2016, all ARCs were current and making scheduled interest payments.

56

Corporate Debt Securities

The Corporation holds corporate debt securities in the form of pooled trust preferred securities, single-issuer trust preferred securities and subordinated debt issued by financial institutions. As of March 31, 2016, these securities had an amortized cost of $95.4 million and an estimated fair value of $89.9 million.

The amortized cost of pooled trust preferred securities is the purchase price of the securities, net of cumulative credit related other-than-temporary impairment charges, determined using an expected cash flows model. The most significant input to the expected cash flows model was the expected payment deferral rate for each pooled trust preferred security. The Corporation evaluates the financial metrics, such as capital ratios and non-performing asset ratios, of the individual financial institution issuers that comprise each pooled trust preferred security to estimate its expected deferral rate.

The fair values for pooled trust preferred securities and certain single-issuer trust preferred securities were based on quotes provided by third-party brokers who determined fair values based predominantly on internal valuation models which were not indicative prices or binding offers.

See "Note 4 - Investment Securities," in the Notes to Consolidated Financial Statements for further discussion related to the Corporation’s other-than-temporary impairment evaluations for debt securities, and see "Note 11 - Fair Value Measurements," in the Notes to Consolidated Financial Statements for further discussion related to the fair values of debt securities.

Item 4. Controls and Procedures

The Corporation carried out an evaluation, under the supervision and with the participation of the Corporation’s management, including the Corporation’s Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of the Corporation’s disclosure controls and procedures pursuant to Rule 13a-15, promulgated under the Securities Exchange Act of 1934 (the "Exchange Act"). Based upon that evaluation, the Corporation’s Chief Executive Officer and Chief Financial Officer concluded that, as of the end of the period covered by this quarterly report, the Corporation’s disclosure controls and procedures are effective. Disclosure controls and procedures are controls and procedures that are designed to ensure that information required to be disclosed in Corporation reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms.

There have been no changes in the Corporation’s internal control over financial reporting during the fiscal quarter covered by this quarterly report that have materially affected, or are reasonably likely to materially affect, the Corporation’s internal control over financial reporting.

PART II – OTHER INFORMATION

Item 1. Legal Proceedings

The information presented in the "Legal Proceedings" section of Note 10 "Commitment and Contingencies" of the Notes to Consolidated Financial Statements is incorporated herein by reference.

As of the date of this report, the Corporation believes that any liabilities, individually or in the aggregate, which may result from the final outcomes of pending proceedings will not have a material adverse effect on the financial condition of the Corporation. However, legal proceedings are often unpredictable, and it is possible that the ultimate resolution of any such matters, if unfavorable, may be material to the Corporation’s results of operations for any particular period, depending, in part, upon the size of the loss or liability imposed and the operating results for the applicable period.

Item 1A. Risk Factors

There have been no material changes to the risk factors as previously disclosed in Part I, Item 1A of the Corporation’s Annual Report on Form 10-K for the year ended December 31, 2015.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation

Basis of Presentation

The accompanying unaudited consolidated financial statements of Fulton Financial Corporation (the "Corporation") have been prepared in conformity with U.S. generally accepted accounting principles ("U.S. GAAP") for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and notes required by U.S. GAAP for complete financial statements. The preparation of financial statements in accordance with U.S. 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 revenues and expenses during the period. Actual results could differ from those estimates. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. These consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2015. Operating results for the three months ended March 31, 2016 are not necessarily indicative of the results that may be expected for the year ending December 31, 2016. The Corporation evaluates subsequent events through the date of filing of this Form 10-Q with the Securities and Exchange Commission ("SEC").

Recently Adopted Accounting Standards

The Corporation adopted FASB ASC Update 2015-02, "Consolidation: Amendments to the Consolidation Analysis" effective January 1, 2016. ASC Update 2015-02 changed the way reporting enterprises evaluate whether: (a) they should consolidate limited partnerships and similar entities, (b) fees paid to a decision maker or service provider are variable interests in a variable interest entity ("VIE"), and (c) variable interests in a VIE held by related parties of the reporting enterprise require the reporting enterprise to consolidate the VIE.ASC Update 2015-02 was effective for public business entities' annual and interim reporting periods that began after December 15, 2015, with earlier adoption permitted. The adoption of ASC Update 2015-02 did not have a material impact on the Corporation's consolidated financial statements.

Effective January 1, 2016, the Corporation adopted FASB ASC Update 2015-03, "Interest - Imputation of Interest" and the updated ASC Update 2015-03 with the issuance of ASC Update 2015-15, “Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements.” ASC Update 2015-03 simplifies the presentation of debt issuances costs. Debt issuance costs related to a recognized debt liability will be presented on the balance sheet as a direct deduction from the debt liability, similar to the presentation of debt discounts. Previously under U.S. GAAP, debt issuance costs were reported on the balance sheet as assets. The costs will continue to be amortized to interest expense using the effective interest method. ASC Update 2015-03 was effective for public business entities' annual and interim reporting periods beginning after December 15, 2015, with earlier adoption permitted.The adoption of ASC Update 2015-03 did not have a material impact on the Corporation's consolidated financial statements.

The Corporation prospectively adopted FASB issued ASC Update 2015-05, "Customer's Accounting for Fees Paid in a Cloud Computing Arrangement" effective January 1, 2016. ASC Update 2015-05 provides explicit guidance to determine when a customer's fees paid in a cloud computing arrangement is for the acquisition of software licenses, services, or both. ASC Update 2015-05 was effective for public business entities' annual and interim reporting periods beginning after December 15, 2015, with earlier adoption permitted.The adoption of ASC Update 2015-05 did not have a material impact on the Corporation's consolidated financial statements.

Recently Issued Accounting Standards

In May 2014, the FASB issued ASC Update 2014-09, "Revenue from Contracts with Customers." This standards update establishes a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. The core principle prescribed by this standards update is that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The standard applies to all contracts with customers, except those that are within the scope of other topics in the FASB ASC. The standard also requires significantly expanded disclosures about revenue recognition. For public business entities, ASC Update 2014-09 is effective for interim and annual reporting periods beginning after December 15, 2017. Early application is not permitted. For the Corporation, this standards update is effective with its March 31, 2018 quarterly report on Form 10-Q. The Corporation is currently evaluating the impact of the adoption of ASC Update 2014-09 on its consolidated financial statements.

In January 2016, the FASB issued ASC Update 2016-01, "Financial Instruments - Overall: Recognition and Measurement of Financial Assets and Financial Liabilities." ASC Update 2016-01 provides guidance regarding the income statement impact of equity investments held by an entity and the recognition of changes in fair value of financial liabilities when the fair value option is elected. ASC Update 2016-01 is effective for public business entities' annual and interim reporting periods beginning after December 15, 2017, with earlier adoption permitted.The Corporation intends to adopt this standards update effective with its March 31, 2018 quarterly report on Form 10-Q and does not expect the adoption of ASC Update 2016-01 to have a material impact on its consolidated financial statements.

In February 2016, the FASB issued ASC Update 2016-02, "Leases." This standards update states that a lessee should recognize the assets and liabilities that arise from all leases with a term greater than 12 months. The core principle requires the lessee to recognize a liability to make lease payments and a "right-of-use" asset. The accounting applied by the lessor is relatively unchanged. The standards update also requires expanded qualitative and quantitative disclosures. For public business entities, ASC Update 2016-02 is effective for interim and annual reporting periods beginning after December 15, 2018. ASC Update 2016-02 mandates a modified retrospective transition for all entities. Early application is permitted. For the Corporation, this standards update is effective with its March 31, 2019 quarterly report on Form 10-Q. The Corporation is currently evaluating the impact of the adoption of ASC Update 2016-02 on its consolidated financial statements.

In March 2016, the FASB issued ASC Update 2016-09, "Stock Compensation: Improvements to Employee Share-Based Payment Accounting." The purpose of this standards update is to simplify several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liability, and classification on the statement of cash flows. ASC Update 2016-09 is effective for interim and annual reporting periods beginning after December 15, 2016. Early application is permitted. For the Corporation, this standards update is effective with its March 31, 2017 quarterly report on Form 10-Q. The Corporation is currently evaluating the impact of the adoption of ASC Update 2016-09 on its consolidated financial statements.

Earnings Per Share [Abstract]

Net Income Per Share

Net Income Per Share

Basic net income per share is calculated as net income divided by the weighted average number of shares outstanding.

Diluted net income per share is calculated as net income divided by the weighted average number of shares outstanding plus the incremental number of shares added as a result of converting common stock equivalents, calculated using the treasury stock method. The Corporation’s common stock equivalents consist of outstanding stock options, restricted stock, restricted stock units ("RSUs") and performance-based restricted stock units ("PSUs"). PSUs are required to be included in weighted average shares outstanding if performance measures, as defined in each PSU award agreement, are met as of the end of the period.

A reconciliation of weighted average shares outstanding used to calculate basic net income per share and diluted net income per share follows:

	Three months ended March 31
	2016	2015
	(in thousands)
Weighted average shares outstanding (basic)	173,331	178,471
Impact of common stock equivalents	1,085	986
Weighted average shares outstanding (diluted)	174,416	179,457

For the three months ended March 31, 2016 and 2015, 885,000 and 2.1 million stock options, respectively, were excluded from the diluted net income per share computation as their effect would have been anti-dilutive.

Securities carried at $1.6 billion as of March 31, 2016 and $1.7 billion as of December 31, 2015 were pledged as collateral to secure public and trust deposits and customer repurchase agreements.

Equity securities include common stocks of financial institutions (estimated fair value of $18.2 million at March 31, 2016 and $20.6 million at December 31, 2015) and other equity investments (estimated fair value of $892,000 at March 31, 2016 and $914,000 at December 31, 2015).

As of March 31, 2016, the financial institutions stock portfolio had a cost basis of $13.4 million and an estimated fair value of $18.2 million, including an investment in a single financial institution with a cost basis of $7.4 million and an estimated fair value of $9.1 million. The estimated fair value of this investment accounted for 50.3% of the estimated fair value of the Corporation's investments in the common stocks of publicly traded financial institutions. No other investment in a single financial institution in the financial institutions stock portfolio exceeded 10% of the portfolio's estimated fair value.

The amortized cost and estimated fair values of debt securities as of March 31, 2016, by contractual maturity, are shown in the following table.

The Corporation’s collateralized mortgage obligations and mortgage-backed securities have contractual terms that generally do not permit the issuer to settle the securities at a price less than the amortized cost of the investment. Because the decline in market value of these securities is attributable to changes in interest rates and not credit quality, and because the Corporation does not have the intent to sell and does not believe it will more likely than not be required to sell any of these securities prior to a recovery of their fair value to amortized cost, the Corporation does not consider these investments to be other-than-temporarily impaired as of March 31, 2016.

As of March 31, 2016, all of the auction rate securities (auction rate certificates, or "ARCs"), were rated above investment grade, with approximately $5.5 million, or 6%, "AAA" rated and $91.8 million, or 94%, "AA" rated. All of the loans underlying the ARCs have principal payments which are guaranteed by the federal government. As of March 31, 2016, all ARCs were current and making scheduled interest payments. Based on management’s evaluations, ARCs with an estimated fair value of $97.3 million were not subject to any other-than-temporary impairment charges as of March 31, 2016. The Corporation does not have the intent to sell and does not believe it will more likely than not be required to sell any of these securities prior to a recovery of their fair value to amortized cost, which may be at maturity.

For its investments in equity securities, particularly its investments in stocks of financial institutions, management evaluates the near-term prospects of the issuers in relation to the severity and duration of the impairment. Based on that evaluation and the Corporation’s ability and intent to hold those investments for a reasonable period of time sufficient for a recovery of fair value, the Corporation does not consider those investments with unrealized holding losses as of March 31, 2016 to be other-than-temporarily impaired.

The majority of the Corporation's available for sale corporate debt securities are issued by financial institutions. The following table presents the amortized cost and estimated fair value of corporate debt securities:

Single-issuer trust preferred securities had an unrealized loss of $7.8 million at March 31, 2016. Six of the 19 single-issuer trust preferred securities were rated below investment grade by at least one ratings agency, with an amortized cost of $11.5 million and an estimated fair value of $9.0 million at March 31, 2016. All of the single-issuer trust preferred securities rated below investment grade were rated "BB" or "Ba". Two single-issuer trust preferred securities with an amortized cost of $3.7 million and an estimated fair value of $2.4 million at March 31, 2016 were not rated by any ratings agency.

Based on management’s evaluations, corporate debt securities with a fair value of $89.9 million were not subject to any other-than-temporary impairment charges as of March 31, 2016. The Corporation does not have the intent to sell and does not believe it will more likely than not be required to sell any of these securities prior to a recovery of their fair value to amortized cost, which may be at maturity.

Allowance for Credit Losses

The allowance for credit losses consists of the allowance for loan losses and the reserve for unfunded lending commitments. The allowance for loan losses represents management’s estimate of incurred losses in the loan portfolio as of the balance sheet date and is recorded as a reduction to loans. The reserve for unfunded lending commitments represents management’s estimate of incurred losses in its unfunded loan commitments and is recorded in other liabilities on the consolidated balance sheets. The allowance for credit losses is increased by charges to expense, through the provision for credit losses, and decreased by charge-offs, net of recoveries.

The Corporation’s allowance for credit losses includes: (1) specific allowances allocated to loans evaluated for impairment under the FASB's ASC Section 310-10-35; and (2) allowances calculated for pools of loans measured for impairment under FASB ASC Subtopic 450-20.

The Corporation segments its loan portfolio by general loan type, or "portfolio segments," as presented in the table under the heading, "Loans, Net of Unearned Income," above. Certain portfolio segments are further disaggregated and evaluated collectively for impairment based on "class segments," which are largely based on the type of collateral underlying each loan. Commercial loans include loans secured by collateral and unsecured loans. Construction loan class segments include loans secured by commercial real estate, loans to commercial borrowers secured by residential real estate and loans to individuals secured by residential real estate. Consumer loan class segments include direct consumer installment loans and indirect automobile loans.

The following table presents the components of the allowance for credit losses:

(1) The unallocated allowance, which was approximately 4% and 5% of the total allowance for credit losses, respectively, as of March 31, 2016 and March 31, 2015, was, in the opinion of management, reasonable and appropriate given that the estimates used in the allocation process are inherently imprecise.

N/A - Not applicable.

Impaired Loans

A loan is considered to be impaired if it is probable that all amounts will not be collected according to the contractual terms of the loan agreement. Impaired loans consist of all loans on non-accrual status and accruing troubled debt restructurings ("TDRs"). An allowance for loan losses is established for an impaired loan if its carrying value exceeds its estimated fair value. Impaired loans to borrowers with total outstanding commitments greater than or equal to $1.0 million are evaluated individually for impairment. Impaired loans to borrowers with total outstanding commitments less than $1.0 million are pooled and measured for impairment collectively.

Based on an evaluation of all relevant credit quality factors, the Corporation recorded a $1.5 million provision for credit losses during the three months ended March 31, 2016, compared to a $3.7 million negative provision for credit losses for the same period in 2015.

All loans individually evaluated for impairment under FASB ASC Section 310-10-35 are measured for losses on a quarterly basis.

As of March 31, 2016 and December 31, 2015, substantially all of the Corporation’s individually evaluated impaired loans with total outstanding balances greater than or equal to $1.0 million were measured based on the estimated fair value of each loan’s collateral. Collateral could be in the form of real estate, in the case of impaired commercial mortgages and construction loans, or business assets, such as accounts receivable or inventory, in the case of commercial and industrial loans. Commercial and industrial loans may also be secured by real property.

As of March 31, 2016 and 2015, approximately 77% and 78%, respectively, of impaired loans with principal balances greater than or equal to $1.0 million, whose primary collateral is real estate, were measured at estimated fair value using state certified third-party appraisals that had been updated in the preceding 12 months.

When updated appraisals are not obtained for loans evaluated for impairment under FASB ASC Section 310-10-35 that are secured by real estate, fair values are estimated based on the original appraisal values, as long as the original appraisal indicated an acceptable loan-to-value position and, in the opinion of the Corporation's internal credit administration staff, there has not been a significant deterioration in the collateral value since the original appraisal was performed. Original appraisals are typically used only when the estimated collateral value, as adjusted for the age of the appraisal, results in a current loan-to-value ratio that is lower than the Corporation's loan-to-value requirements for new loans, generally less than 70%.

As of March 31, 2016 and December 31, 2015, there were $47.8 million and $50.0 million, respectively, of impaired loans that did not have a related allowance for loan loss. The estimated fair values of the collateral securing these loans exceeded their carrying amount, or they were previously charged down to realizable collateral values. Accordingly, no specific valuation allowance was considered to be necessary.

The following is a summary of the Corporation's internal risk rating categories:

• Pass: These loans do not currently pose undue credit risk and can range from the highest to average quality, depending on the degree of potential risk.

• Special Mention: These loans constitute an undue and unwarranted credit risk, but not to a point of justifying a classification of substandard. Loans in this category are currently acceptable, but are nevertheless potentially weak.

• Substandard or Lower: These loans are inadequately protected by current sound worth and paying capacity of the borrower. There exists a well-defined weakness or weaknesses that jeopardize the normal repayment of the debt.

The risk rating process allows management to identify credits that potentially carry more risk in a timely manner and to allocate resources to managing troubled accounts. The Corporation believes that internal risk ratings are the most relevant credit quality indicator for the class segments presented above. The migration of loans through the various internal risk rating categories is a significant component of the allowance for credit loss methodology, which bases the probability of default on this migration. Assigning risk ratings involves judgment. Risk ratings are initially assigned to loans by loan officers and are reviewed on a regular basis by credit administration staff. The Corporation's loan review officers provide a separate assessment of risk rating accuracy. Ratings may be changed based on the ongoing monitoring procedures performed by loan officers or credit administration staff, or if specific loan review activities identify a deterioration or an improvement in the loan.

The Corporation does not assign internal risk ratings to smaller balance, homogeneous loans, such as home equity, residential mortgage, consumer, lease receivables and construction loans to individuals secured by residential real estate. For these loans, the most relevant credit quality indicator is delinquency status. The migration of loans through the various delinquency status categories is a significant component of the allowance for credit losses methodology for those loans, which bases the probability of default on this migration.

The following table presents a summary of delinquency and non-performing status for home equity, real estate - residential mortgages, construction loans to individuals and consumer, leasing and other loans by class segment:

Mortgage Servicing Rights

Mortgage Servicing Rights

The following table summarizes the changes in mortgage servicing rights ("MSRs"), which are included in other assets on the consolidated balance sheets:

	Three months ended March 31
	2016			2015
	(in thousands)
Amortized cost:
Balance at beginning of period	$	40,944		$	42,148
Originations of mortgage servicing rights	920			1,557
Amortization	(1,669		)	(1,902		)
Balance at end of period	$	40,195		$	41,803

MSRs represent the economic value of existing contractual rights to service mortgage loans that have been sold. Accordingly, actual and expected prepayments of the underlying mortgage loans can impact the value of MSRs. The Corporation accounts for MSRs at the lower of amortized cost or fair value.

The fair value of MSRs is estimated by discounting the estimated cash flows from servicing income, net of expense, over the expected life of the underlying loans at a discount rate commensurate with the risk associated with these assets. Expected life is based on the contractual terms of the loans, as adjusted for prepayment projections. No valuation allowance was necessary as of March 31, 2016 or 2015.

As of March 31, 2016, the estimated fair value of MSRs was $40.8 million, which exceeded their book value.

Stock-Based Compensation

Stock-Based Compensation

The Corporation grants equity awards to employees, consisting of stock options, restricted stock, RSUs and PSUs under its Amended and Restated Equity and Cash Incentive Compensation Plan ("Employee Equity Plan"). In addition, employees may purchase stock under the Corporation’s Employee Stock Purchase Plan. The fair value of equity awards granted to employees is recognized as compensation expense over the period during which employees are required to provide service in exchange for such awards. Compensation expense for PSUs is also recognized over the period during which employees are required to provide service in exchange for such awards, however, compensation expense may vary based on the expectations for actual performance relative to defined performance measures.

The Corporation also grants equity awards to non-employee members of its board of directors under the 2011 Directors’ Equity Participation Plan ("Directors’ Plan"). Under the Directors’ Plan, the Corporation can grant equity awards to non-employee holding company and subsidiary bank directors in the form of stock options, restricted stock or common stock.

Equity awards issued under the Employee Equity Plan are generally granted annually and become fully vested over or after a three-year vesting period. The vesting period for non-performance-based awards represents the period during which employees are required to provide service in exchange for such awards. Equity awards under the Directors' Plan generally vest immediately upon grant. Certain events, as defined in the Employee Equity Plan and the Directors' Plan, result in the acceleration of the vesting of equity awards.

The following table presents compensation expense and the related tax benefits for equity awards recognized in the consolidated statements of income:

	Three months ended March 31
	2016			2015
	(in thousands)
Stock-based compensation expense	$	1,436		$	1,071
Tax benefit	(433		)	(292		)
Stock-based compensation expense, net of tax	$	1,003		$	779

Stock option fair values are estimated through the use of the Black-Scholes valuation methodology as of the date of grant. Stock options carry terms of up to ten years. Fair values for restricted stock, RSUs and a majority of PSUs are based on the trading price of the Corporation’s stock on the date of grant and earn dividends during the vesting period, which are forfeitable if the awards do not vest. The fair value of certain PSUs are estimated through the use of the Monte Carlo valuation methodology as of the date of grant.

As of March 31, 2016, the Employee Equity Plan had 11.5 million shares reserved for future grants through 2023, and the Directors’ Plan had approximately 396,000 shares reserved for future grants through 2021.

Employee Benefit Plans

The Corporation maintains a defined benefit pension plan ("Pension Plan") for certain employees, which was curtailed in 2008. Contributions to the Pension Plan are actuarially determined and funded annually, if required. Pension Plan assets are invested in: money markets; fixed income securities, including corporate bonds, U.S. Treasury securities and common trust funds; and equity securities, including common stocks and common stock mutual funds.

(1) Service cost was related to administrative costs associated with the plan and was not due to the accrual of additional participant benefits.

The Corporation provides benefits under a postretirement benefits plan ("Postretirement Plan") to certain retirees who were employees of the Corporation prior to January 1, 1998 and retired from employment with the Corporation prior to February 1, 2014.

The net periodic cost (benefit) of the Corporation’s Postretirement Plan consisted of the following components:

Derivative Financial Instruments

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Financial Instruments

Derivative Financial Instruments

The Corporation manages its exposure to certain interest rate and foreign currency risks through the use of derivatives. None of the Corporation's outstanding derivative contracts are designated as hedges, and none are entered into for speculative purposes. Derivative instruments are carried at fair value, with changes in fair values recognized in earnings as components of non-interest income and non-interest expense on the consolidated statements of income.

Derivative contracts create counterparty credit risk with both the Corporation's customers and with institutional derivative counterparties. The Corporation manages counterparty credit risk through its credit approval processes, monitoring procedures and obtaining adequate collateral, when the Corporation determines it is appropriate to do so and in accordance with counterparty contracts.

Mortgage Banking Derivatives

In connection with its mortgage banking activities, the Corporation enters into commitments to originate certain fixed rate residential mortgage loans for customers, also referred to as interest rate locks. In addition, the Corporation enters into forward commitments for the future sales or purchases of mortgage-backed securities to or from third-party counterparties to hedge the effect of changes in interest rates on the values of both the interest rate locks and mortgage loans held for sale. Forward sales commitments may also be in the form of commitments to sell individual mortgage loans at a fixed price at a future date. The amount necessary to settle each interest rate lock is based on the price that secondary market investors would pay for loans with similar characteristics, including interest rate and term, as of the date fair value is measured. Gross derivative assets and liabilities are recorded in other assets and other liabilities, respectively, on the consolidated balance sheets, and changes in fair values during the period are recorded in mortgage banking income on the consolidated statements of income.

Interest Rate Swaps

The Corporation enters into interest rate swaps with certain qualifying commercial loan customers to meet their interest rate risk management needs. The Corporation simultaneously enters into interest rate swaps with dealer counterparties, with identical notional amounts and terms. The net result of these interest rate swaps is that the customer pays a fixed rate of interest and the Corporation receives a floating rate. These interest rate swaps are derivative financial instruments that are recorded at their fair value in other assets and other liabilities on the consolidated balance sheets, with changes in fair value during the period recorded in other non-interest expense on the consolidated statements of income.

Foreign Exchange Contracts

The Corporation enters into foreign exchange contracts to accommodate the needs of its customers. Foreign exchange contracts are commitments to buy or sell foreign currency on a future date at a contractual price. The Corporation offsets its foreign exchange contract exposure with customers by entering into contracts with third-party correspondent financial institutions to mitigate its exposure to fluctuations in foreign currency exchange rates. The Corporation also holds certain amounts of foreign currency with international correspondent banks. The Corporation's policy limits the total net foreign currency open positions, which includes all outstanding contracts and foreign account balances, to $500,000. Gross derivative assets and liabilities are recorded in other assets and other liabilities, respectively, on the consolidated balance sheets, with changes in fair values during the period recorded within other service charges and fees on the consolidated statements of income.

The following table presents a summary of the notional amounts and fair values of derivative financial instruments:

Fair Value Option

U.S. GAAP permits entities to measure many financial instruments and certain other items at fair value and requires certain disclosures for amounts for which the fair value option is applied. The Corporation has elected to measure mortgage loans held for sale at fair value to more accurately reflect the financial results of its mortgage banking activities in its consolidated financial statements. Derivative financial instruments related to these activities are also recorded at fair value, as noted above. The Corporation determines fair value for its mortgage loans held for sale based on the price that secondary market investors would pay for loans with similar characteristics, including interest rate and term, as of the date fair value is measured. Changes in fair values during the period are recorded as components of mortgage banking income on the consolidated statements of income. Interest income earned on mortgage loans held for sale is classified in interest income on the consolidated statements of income.

The following table presents a summary of the Corporation’s mortgage loans held for sale:

	March 31, 2016		December 31, 2015
	(in thousands)
Cost	$	19,187	$	16,584
Fair value	19,719		16,886

During the three months ended March 31, 2016 and 2015, the Corporation recorded gains related to changes in fair values of mortgage loans held for sale of $230,000 and $261,000, respectively.

Balance Sheet Offsetting

Certain financial assets and liabilities may be eligible for offset on the consolidated balance sheets because they are subject to master netting arrangements or similar agreements. The Corporation elects to not offset assets and liabilities subject to such arrangements on the consolidated financial statements.

The Corporation is a party to interest rate swap transactions with financial institution counterparties and customers, disclosed in detail above. Under these agreements, the Corporation has the right to net-settle multiple contracts with the same counterparty in the event of default on, or termination of, any one contract. Cash collateral is posted by the party with a net liability position or the right to reclaim cash collateral exists in a net asset position in accordance with contract thresholds and can be used to settle the fair value of the interest rate swap agreements in the event of default.

The Corporation is also a party to foreign currency exchange contracts with financial institution counterparties, under which the Corporation has the right to net-settle multiple contracts with the same counterparty in the event of default on, or termination of, any one contract. As with interest rate swap contracts, cash collateral is posted by the party with a net liability position or the right to reclaim cash collateral exists in a net asset position in accordance with contract thresholds and can be used to settle the fair value of the foreign currency exchange contracts in the event of default.

The Corporation also enters into agreements with customers in which it sells securities subject to an obligation to repurchase the same or similar securities, referred to as repurchase agreements. Under these agreements, the Corporation may transfer legal control over the assets but still maintain effective control through agreements that both entitle and obligate the Corporation to repurchase the assets. Therefore, repurchase agreements are reported as secured borrowings, classified in short-term borrowings on the consolidated balance sheets, while the securities underlying the repurchase agreements remain classified with investment securities on the consolidated balance sheets. The Corporation has no intention of setting off these amounts. Therefore, these repurchase agreements are not eligible for offset.

The following table presents the Corporation's financial instruments that are eligible for offset, and the effects of offsetting, on the consolidated balance sheets:

For derivative liabilities, amounts represent any derivative asset fair values that could be offset in the event of counterparty or customer default.

(2) Amounts represent cash collateral posted or the right to reclaim cash collateral on interest rate swap transactions with financial institution counterparties and on foreign exchange derivative transactions with correspondent banks.

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingencies

Commitments and Contingencies

Commitments

The Corporation is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers.

Those financial instruments include commitments to extend credit and letters of credit, which involve, to varying degrees, elements of credit risk and interest rate risk in excess of the amounts recognized on the Corporation’s consolidated balance sheets. Exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit and letters of credit is represented by the outstanding amount of those instruments.

The outstanding amounts of commitments to extend credit and letters of credit as of the dates indicated were as follows:

	March 31, 2016		December 31, 2015
	(in thousands)
Commitments to extend credit	$	5,932,144	$	5,784,138
Standby letters of credit	369,932		374,729
Commercial letters of credit	37,596		39,529

The Corporation records a reserve for unfunded lending commitments, which represents management’s estimate of losses associated with unused commitments to extend credit. See Note 5, "Loans and Allowance for Credit Losses," for additional details.

Residential Lending

Residential mortgages originated and sold by the Corporation consist primarily of conforming, prime loans sold to government sponsored agencies, such as the Federal National Mortgage Association ("Fannie Mae") and the Federal Home Loan Mortgage Corporation ("Freddie Mac"). The Corporation also sells certain prime loans it originates to non-government sponsored agency investors.

The Corporation provides customary representations and warranties to government sponsored entities and investors that specify, among other things, that the loans have been underwritten to the standards established by the government sponsored entity or investor. The Corporation may be required to repurchase a loan, or reimburse the government sponsored entity or investor for a credit loss incurred on a loan, if it is determined that the representations and warranties have not been met. Such repurchases or reimbursements generally result from an underwriting or documentation deficiency. As of both March 31, 2016 and December 31, 2015, total outstanding repurchase requests totaled approximately $543,000.

From 2000 to 2011, the Corporation sold loans to the Federal Home Loan Bank of Pittsburgh under its Mortgage Partnership Finance Program ("MPF Program"). The Corporation provided a "credit enhancement" for residential mortgage loans sold under the MPF Program whereby it would assume credit losses in excess of a defined "First Loss Account," or "FLA" balance, up to specified amounts. The FLA is funded by the Federal Home Loan Bank of Pittsburgh based on a percentage of the outstanding principal balance of loans sold. As of March 31, 2016, the unpaid principal balance of loans sold under the MPF Program was approximately $120 million. As of March 31, 2016 and December 31, 2015, the reserve for estimated credit losses related to loans sold under the MPF Program was $2.0 million and $1.8 million, respectively. Required reserves are calculated based on delinquency status and estimated loss rates established through the Corporation's existing allowance for credit losses methodology for residential mortgage loans.

As of March 31, 2016 and December 31, 2015, the total reserve for losses on residential mortgage loans sold was $2.7 million and $2.6 million, respectively, including both reserves for credit losses under the MPF Program and reserves for representation and warranty exposures. Management believes that the reserves recorded as of March 31, 2016 are adequate. However, declines in collateral values, the identification of additional loans to be repurchased, or a deterioration in the credit quality of loans sold under the MPF Program could necessitate additional reserves, established through charges to earnings, in the future.

Legal Proceedings

The Corporation and its subsidiaries are involved in various legal proceedings in the ordinary course of business of the Corporation. The Corporation periodically evaluates the possible impact of pending litigation matters based on, among other factors, the advice of counsel, available insurance coverage and recorded liabilities and reserves for probable legal liabilities and costs. In addition, from time to time, the Corporation is the subject of investigations or other forms of regulatory or governmental inquiry covering a range of possible issues and, in some cases, these may be part of similar reviews of the specified activities of other industry participants. These inquiries could lead to administrative, civil or criminal proceedings, and could possibly result in fines, penalties, restitution or the need to alter the Corporation’s business practices, and cause the Corporation to incur additional costs. The Corporation’s practice is to cooperate fully with regulatory and governmental investigations.

As of the date of this report, the Corporation believes that any liabilities, individually or in the aggregate, which may result from the final outcomes of pending proceedings will not have a material adverse effect on the financial condition of the Corporation. However, legal proceedings are often unpredictable, and it is possible that the ultimate resolution of any such matters, if unfavorable, may be material to the Corporation’s results of operations for any particular period, depending, in part, upon the size of the loss or liability imposed and the operating results for the applicable period.

BSA/AML Enforcement Orders

The Corporation and each of its bank subsidiaries are subject to regulatory enforcement orders issued during 2014 and 2015 by their respective federal and state bank regulatory agencies relating to identified deficiencies in the Corporation’s centralized Bank Secrecy Act and anti-money laundering compliance program (the "BSA/AML Compliance Program"), which was designed to comply with the requirements of the Bank Secrecy Act, the USA Patriot Act of 2001 and related anti-money laundering regulations (collectively, the "BSA/AML Requirements"). The regulatory enforcement orders, which are in the form of consent orders or orders to cease and desist issued upon consent ("Consent Orders"), generally require, among other things, that the Corporation and its bank subsidiaries undertake a number of required actions to strengthen and enhance the BSA/AML Compliance Program, and, in some cases, conduct retrospective reviews of past account activity and transactions, as well as certain reports filed in accordance with the BSA/AML Requirements, to determine whether suspicious activity and certain transactions in currency were properly identified and reported in accordance with the BSA/AML Requirements. In addition to requiring strengthening and enhancement of the BSA/AML Compliance Program, while the Consent Orders remain in effect, the Corporation is subject to certain restrictions on expansion activities of the Corporation and its bank subsidiaries. Further, any failure to comply with the requirements of any of the Consent Orders involving the Corporation or its bank subsidiaries could result in further enforcement actions, the imposition of material restrictions on the activities of the Corporation or its bank subsidiaries, or the assessment of fines or penalties.

Fair Lending Investigation

During the second quarter of 2015, Fulton Bank, N.A. (the "Bank"), the Corporation’s largest bank subsidiary, received a letter from the U.S. Department of Justice (the "Department") indicating that the Department had initiated an investigation regarding potential violations of fair lending laws by the Bank in certain of its geographies. The Bank is cooperating with the Department and responding to the Department’s requests for information. Although the Corporation is not able to predict the outcome of the Department’s investigation, it could result in legal proceedings the resolution of which could potentially involve a settlement, fines or other remedial actions.

Agostino, et al. Litigation

Fulton Bank, N.A. (the "Bank"), the Corporation’s largest bank subsidiary, and two unrelated, third-party defendants, Ameriprise Financial Services, Inc. and Riverview Bank, have been named as defendants in a lawsuit brought on behalf of a group of 58 plaintiffs filed on March 31, 2016 in the Court of Common Pleas for Dauphin County, Pennsylvania (Agostino, et al. v. Ameriprise Financial Services, Inc., et al., No. 2016-CV-2048-CV). The plaintiffs in this action, who are individuals, trustees of certain irrevocable trusts or the executors of the estates of deceased individuals, were clients of Jeffrey M. Mottern, a now deceased attorney, who is alleged to have operated a Ponzi scheme which defrauded the plaintiffs over a period of years through the sale of fictitious, high-yielding investments or by otherwise misappropriating funds entrusted to Mr. Mottern. Mr. Mottern is alleged to have used the proceeds of these activities to engage in speculative securities trading, which incurred significant losses, and for Mr. Mottern’s personal expenses. The allegations against the Bank relate to a commercial checking account at the Bank maintained by Mr. Mottern in connection with Mr. Mottern’s law practice. The lawsuit alleges that the Bank is liable to the plaintiffs for failing to properly monitor Mr. Mottern’s checking account and detect Mr. Mottern’s fraudulent activity, and specifically alleges that the Bank aided and abetted Mr. Mottern’s: (1) fraud; (2) breach of fiduciary duty; (3) violations of the Pennsylvania Unfair Trade Practices and Consumer Protection Law; and (4) conversion. Similar claims have been asserted against Ameriprise Financial Services, Inc. and Riverview Bank, which allegedly maintained a personal brokerage account and a trust account for client or other third-party funds, respectively, for Mr. Mottern. The lawsuit seeks damages from the defendants, including the Bank, alleged to be in excess of $11.3 million, treble damages and attorneys’ fees with respect to alleged violations of the Pennsylvania Unfair Trade Practices and Consumer Protection Law, punitive damages, plus interest and costs. On April 29, 2016, the Bank filed a Notice of Removal to remove this lawsuit to the United States District Court for the Middle District of Pennsylvania.

Fair Value Disclosures [Abstract]

Fair Value Measurements

Fair Value Measurements

FASB ASC Topic 820 establishes a fair value hierarchy for the inputs to valuation techniques used to measure assets and liabilities at fair value using the following three categories (from highest to lowest priority):

• Level 1 – Inputs that represent quoted prices for identical instruments in active markets.

• Level 2 – Inputs that represent quoted prices for similar instruments in active markets, or quoted prices for identical instruments in non-active markets. Also includes valuation techniques whose inputs are derived principally from observable market data other than quoted prices, such as interest rates or other market-corroborated means.

• Level 3 – Inputs that are largely unobservable, as little or no market data exists for the instrument being valued.

The Corporation has categorized all assets and liabilities measured at fair value on both a recurring and nonrecurring basis into the above three levels.

The following tables present summaries of the Corporation’s assets and liabilities measured at fair value on a recurring basis and reported on the consolidated balance sheets:

Other liabilities	$	15,914	$	33,010	$	—	$	48,924

The valuation techniques used to measure fair value for the items in the preceding tables are as follows:

• Mortgage loans held for sale – This category consists of mortgage loans held for sale that the Corporation has elected to measure at fair value. Fair values as of March 31, 2016 and December 31, 2015 were measured based on the price that secondary market investors were offering for loans with similar characteristics. See Note 9, "Derivative Financial Instruments" for details related to the Corporation’s election to measure assets and liabilities at fair value.

• Available for sale investment securities – Included in this asset category are both equity and debt securities. Level 2 available for sale debt securities are valued by a third-party pricing service commonly used in the banking industry. The pricing service uses pricing models that vary based on asset class and incorporate available market information, including quoted prices of investment securities with similar characteristics. Because many fixed income securities do not trade on a daily basis, pricing models use available information, as applicable, through processes such as benchmark yield curves, benchmarking of like securities, sector groupings, and matrix pricing.

Standard market inputs include: benchmark yields, reported trades, broker/dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers and reference data, including market research publications. For certain security types, additional inputs may be used, or some of the standard market inputs may not be applicable.

Management tests the values provided by the pricing service by obtaining securities prices from an alternative third-party source and comparing the results. This test is done for approximately 80% of the securities valued by the pricing service. Generally, differences by security in excess of 5% are researched to reconcile the difference.

• Equity securities – Equity securities consist of common stocks of financial institutions ($18.2 million at March 31, 2016 and $20.6 million at December 31, 2015) and other equity investments ($892,000 at March 31, 2016 and $914,000 at December 31, 2015). These Level 1 investments are measured at fair value based on quoted prices for identical securities in active markets.

• U.S. Government securities/U.S. Government sponsored agency securities/State and municipal securities/Collateralized mortgage obligations/Mortgage-backed securities – These debt securities are classified as Level 2 investments. Fair values are determined by a third-party pricing service, as detailed above.

• Corporate debt securities – This category consists of subordinated debt issued by financial institutions ($49.3 million at March 31, 2016 and $53.1 million at December 31, 2015), single-issuer trust preferred securities issued by financial institutions ($35.9 million at March 31, 2016 and $39.1 million at December 31, 2015), pooled trust preferred securities issued by financial institutions ($706,000 at both March 31, 2016 and December 31, 2015) and other corporate debt issued by non-financial institutions ($4.0 million at both March 31, 2016 and December 31, 2015).

Level 2 investments include the Corporation’s holdings of subordinated debt, other corporate debt issued by non-financial institutions and $33.5 million and $36.5 million of single-issuer trust preferred securities held at March 31, 2016 and December 31, 2015, respectively. The fair values for these corporate debt securities are determined by a third-party pricing service, as detailed above.

Level 3 investments include the Corporation’s investments in pooled trust preferred securities ($706,000 at both March 31, 2016 and December 31, 2015) and certain single-issuer trust preferred securities ($2.4 million at March 31, 2016 and $2.6 million at December 31, 2015). The fair values of these securities were determined based on quotes provided by third-party brokers who determined fair values based predominantly on internal valuation models which were not indicative prices or binding offers. The Corporation’s third-party pricing service cannot derive fair values for these securities primarily due to inactive markets for similar investments. Level 3 values are tested by management primarily through trend analysis, by comparing current values to those reported at the end of the preceding calendar quarter, and determining if they are reasonable based on price and spread movements for this asset class.

• Auction rate securities – Due to their illiquidity, ARCs are classified as Level 3 investments and are valued through the use of an expected cash flows model prepared by a third-party valuation expert. The assumptions used in preparing the expected cash flows model include estimates for coupon rates, time to maturity and market rates of return. The most significant unobservable input to the expected cash flows model is an assumed return to market liquidity sometime in the next five years. If the assumed return to market liquidity was lengthened beyond the next five years, this would result in a decrease in the fair value of these ARCs. The Corporation believes that the trusts underlying the ARCs will self-liquidate as student loans are repaid. Level 3 fair values are tested by management through the performance of a trend analysis of the market price and discount rate. Changes in the price and discount rates are compared to changes in market data, including bond ratings, parity ratios, balances and delinquency levels.

Other assets – Included in this category are the following:

• Level 1 assets include mutual funds that are held in trust for employee deferred compensation plans ($15.7 million at March 31, 2016 and $15.6 million at December 31, 2015) and the fair value of foreign currency exchange contracts ($1.0 million at March 31, 2016 and $547,000 at December 31, 2015). The mutual funds and foreign exchange prices used to measure these items at fair value are based on quoted prices for identical instruments in active markets.

• Level 2 assets include the fair value of mortgage banking derivatives in the form of interest rate locks and forward commitments with secondary market investors ($2.5 million at March 31, 2016 and $1.5 million at December 31, 2015) and the fair value of interest rate swaps ($62.4 million at March 31, 2016 and $33.0 million at December 31, 2015). The fair values of the Corporation’s interest rate locks, forward commitments and interest rate swaps represent the amounts that would be required to settle the derivative financial instruments at the balance sheet date. See Note 9, "Derivative Financial Instruments," for additional information.

Other liabilities – Included in this category are the following:

• Level 1 liabilities include employee deferred compensation liabilities which represent amounts due to employees under deferred compensation plans ($15.7 million at March 31, 2016 and $15.6 million at December 31, 2015) and the fair value of foreign currency exchange contracts ($722,000 at March 31, 2016 and $331,000 at December 31, 2015). The fair value of these liabilities are determined in the same manner as the related assets, as described under the heading "Other assets" above.

• Level 2 liabilities include the fair value of mortgage banking derivatives in the form of interest rate locks and forward commitments with secondary market investors ($925,000 at March 31, 2016 and $40,000 at December 31, 2015) and the fair value of interest rate swaps ($62.4 million at March 31, 2016 and $33.0 million at December 31, 2015). The fair values of these liabilities are determined in the same manner as the related assets, as described under the heading "Other assets" above.

The following table presents the changes in the Corporation’s available for sale investment securities measured at fair value on a recurring basis using unobservable inputs (Level 3):

	Three months ended March 31, 2016
	Pooled Trust Preferred Securities			Single-issuer Trust Preferred Securities			ARCs
	(in thousands)
Balance at December 31, 2015	$	706		$	2,630		$	98,059
Unrealized adjustment to fair value (1)	—			(233		)	(832		)
Discount accretion (2)	—			3			99
Balance at March 31, 2016	$	706		$	2,400		$	97,326
	Three months ended March 31, 2015
Balance at December 31, 2014	$	4,088		$	3,820		$	100,941
Sales	(3,079		)	—			—
Unrealized adjustment to fair value (1)	190			(2		)	332
Settlements - calls	(117		)	—			(2,446		)
Discount accretion (2)	2			2			105
Balance at March 31, 2015	$	1,084		$	3,820		$	98,932

(1) Pooled trust preferred securities, single-issuer trust preferred securities and ARCs are classified as available for sale investment securities; as such, the unrealized adjustment to fair value was recorded as an unrealized holding gain (loss) and included as a component of available for sale investment securities on the consolidated balance sheets.

(2) Included as a component of net interest income on the consolidated statements of income.

Certain financial assets are not measured at fair value on an ongoing basis, but are subject to fair value measurement in certain circumstances, such as upon their acquisition or when there is evidence of impairment. The following table presents the Corporation’s financial assets measured at fair value on a nonrecurring basis and reported on the Corporation’s consolidated balance sheets:

	March 31, 2016
	Level 1		Level 2		Level 3		Total
	(in thousands)
Net loans	$	—	$	—	$	131,875	$	131,875
Other financial assets	—		—		51,141		51,141
Total assets	$	—	$	—	$	183,016	$	183,016

	December 31, 2015
	Level 1		Level 2		Level 3		Total
	(in thousands)
Net loans	$	—	$	—	$	138,491	$	138,491
Other financial assets	—		—		52,043		52,043
Total assets	$	—	$	—	$	190,534	$	190,534

The valuation techniques used to measure fair value for the items in the table above are as follows:

• Net loans – This category consists of loans that were evaluated for impairment under FASB ASC Section 310-10-35 and have been classified as Level 3 assets. The amount shown is the balance of impaired loans, net of the related allowance for loan losses. See Note 5, "Loans and Allowance for Credit Losses," for additional details.

• Other financial assets – This category includes OREO ($10.9 million at March 31, 2016 and $11.1 million at December 31, 2015) and MSRs ($40.2 million at March 31, 2016 and $40.9 million at December 31, 2015), both classified as Level 3 assets.

Fair values for OREO were based on estimated selling prices less estimated selling costs for similar assets in active markets.

MSRs are initially recorded at fair value upon the sale of residential mortgage loans to secondary market investors. MSRs are amortized as a reduction to servicing income over the estimated lives of the underlying loans. MSRs are stratified and evaluated for impairment by comparing each stratum's carrying amount to its estimated fair value. Fair values are determined at the end of each quarter through a discounted cash flows valuation performed by a third-party valuation expert. Significant inputs to the valuation included expected net servicing income, the discount rate and the expected life of the underlying loans. Expected life is based on the contractual terms of the loans, as adjusted for prepayment projections. The weighted average annual constant prepayment rate and the weighted average discount rate used in the March 31, 2016 valuation were 12.5% and 9.6%, respectively. Management tests the reasonableness of the significant inputs to the third-party valuation in comparison to market data.

As required by FASB ASC Section 825-10-50, the following table details the book values and estimated fair values of the Corporation’s financial instruments as of March 31, 2016 and December 31, 2015. In addition, a general description of the methods and assumptions used to estimate such fair values is also provided.

	March 31, 2016				December 31, 2015
	Book Value		Estimated Fair Value		Book Value		Estimated Fair Value
	(in thousands)
FINANCIAL ASSETS
Cash and due from banks	$	83,479	$	83,479	$	101,120	$	101,120
Interest-bearing deposits with other banks	346,582		346,582		230,300		230,300
Federal Reserve Bank and Federal Home Loan Bank stock	61,478		61,478		62,216		62,216

Other financial assets (1)	200,456		200,456		166,920		166,920
FINANCIAL LIABILITIES
Demand and savings deposits	$	11,537,266	$	11,537,266	$	11,267,367	$	11,267,367
Time deposits	2,867,014		2,961,225		2,864,950		2,862,868
Short-term borrowings	352,883		352,883		497,663		497,663
Accrued interest payable	13,567		13,567		10,724		10,724
Other financial liabilities (1)	220,267		220,267		190,927		190,927
Federal Home Loan Bank advances and long-term debt	965,654		990,222		949,542		959,315

(1) These financial instruments, or certain financial instruments in these categories, are measured at fair value on the Corporation’s consolidated balance sheets. Descriptions of the fair value determinations for these financial instruments are disclosed above.

Fair values of financial instruments are significantly affected by the assumptions used, principally the timing of future cash flows and discount rates. Because assumptions are inherently subjective in nature, the estimated fair values cannot be substantiated by comparison to independent market quotes and, in many cases, the estimated fair values could not necessarily be realized in an immediate sale or settlement of the instrument. The aggregate fair value amounts presented do not necessarily represent management’s estimate of the underlying value of the Corporation.

For short-term financial instruments, defined as those with remaining maturities of 90 days or less, and excluding those recorded at fair value on the Corporation’s consolidated balance sheets, book value was considered to be a reasonable estimate of fair value.

The following instruments are predominantly short-term:

Assets	Liabilities
Cash and due from banks	Demand and savings deposits
Interest-bearing deposits with other banks	Short-term borrowings
Accrued interest receivable	Accrued interest payable

Federal Reserve Bank and Federal Home Loan Bank ("FHLB") stock represent restricted investments and are carried at cost on the consolidated balance sheets.

Fair values for loans and time deposits were estimated by discounting future cash flows using the current rates at which similar loans would be made to borrowers and similar deposits would be issued to customers for the same remaining maturities. Fair values estimated in this manner do not fully incorporate an exit price approach to fair value, as defined in FASB ASC Topic 820.

The fair values of FHLB advances and long-term debt were estimated by discounting the remaining contractual cash flows using a rate at which the Corporation could issue debt with similar remaining maturities as of the balance sheet date. These borrowings would be categorized in Level 2 liabilities under FASB ASC Topic 820.

New Accounting Pronouncements, Policy

Recently Adopted Accounting Standards

The Corporation adopted FASB ASC Update 2015-02, "Consolidation: Amendments to the Consolidation Analysis" effective January 1, 2016. ASC Update 2015-02 changed the way reporting enterprises evaluate whether: (a) they should consolidate limited partnerships and similar entities, (b) fees paid to a decision maker or service provider are variable interests in a variable interest entity ("VIE"), and (c) variable interests in a VIE held by related parties of the reporting enterprise require the reporting enterprise to consolidate the VIE.ASC Update 2015-02 was effective for public business entities' annual and interim reporting periods that began after December 15, 2015, with earlier adoption permitted. The adoption of ASC Update 2015-02 did not have a material impact on the Corporation's consolidated financial statements.

Effective January 1, 2016, the Corporation adopted FASB ASC Update 2015-03, "Interest - Imputation of Interest" and the updated ASC Update 2015-03 with the issuance of ASC Update 2015-15, “Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements.” ASC Update 2015-03 simplifies the presentation of debt issuances costs. Debt issuance costs related to a recognized debt liability will be presented on the balance sheet as a direct deduction from the debt liability, similar to the presentation of debt discounts. Previously under U.S. GAAP, debt issuance costs were reported on the balance sheet as assets. The costs will continue to be amortized to interest expense using the effective interest method. ASC Update 2015-03 was effective for public business entities' annual and interim reporting periods beginning after December 15, 2015, with earlier adoption permitted.The adoption of ASC Update 2015-03 did not have a material impact on the Corporation's consolidated financial statements.

The Corporation prospectively adopted FASB issued ASC Update 2015-05, "Customer's Accounting for Fees Paid in a Cloud Computing Arrangement" effective January 1, 2016. ASC Update 2015-05 provides explicit guidance to determine when a customer's fees paid in a cloud computing arrangement is for the acquisition of software licenses, services, or both. ASC Update 2015-05 was effective for public business entities' annual and interim reporting periods beginning after December 15, 2015, with earlier adoption permitted.The adoption of ASC Update 2015-05 did not have a material impact on the Corporation's consolidated financial statements.

Recently Issued Accounting Standards

In May 2014, the FASB issued ASC Update 2014-09, "Revenue from Contracts with Customers." This standards update establishes a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. The core principle prescribed by this standards update is that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The standard applies to all contracts with customers, except those that are within the scope of other topics in the FASB ASC. The standard also requires significantly expanded disclosures about revenue recognition. For public business entities, ASC Update 2014-09 is effective for interim and annual reporting periods beginning after December 15, 2017. Early application is not permitted. For the Corporation, this standards update is effective with its March 31, 2018 quarterly report on Form 10-Q. The Corporation is currently evaluating the impact of the adoption of ASC Update 2014-09 on its consolidated financial statements.

In January 2016, the FASB issued ASC Update 2016-01, "Financial Instruments - Overall: Recognition and Measurement of Financial Assets and Financial Liabilities." ASC Update 2016-01 provides guidance regarding the income statement impact of equity investments held by an entity and the recognition of changes in fair value of financial liabilities when the fair value option is elected. ASC Update 2016-01 is effective for public business entities' annual and interim reporting periods beginning after December 15, 2017, with earlier adoption permitted.The Corporation intends to adopt this standards update effective with its March 31, 2018 quarterly report on Form 10-Q and does not expect the adoption of ASC Update 2016-01 to have a material impact on its consolidated financial statements.

In February 2016, the FASB issued ASC Update 2016-02, "Leases." This standards update states that a lessee should recognize the assets and liabilities that arise from all leases with a term greater than 12 months. The core principle requires the lessee to recognize a liability to make lease payments and a "right-of-use" asset. The accounting applied by the lessor is relatively unchanged. The standards update also requires expanded qualitative and quantitative disclosures. For public business entities, ASC Update 2016-02 is effective for interim and annual reporting periods beginning after December 15, 2018. ASC Update 2016-02 mandates a modified retrospective transition for all entities. Early application is permitted. For the Corporation, this standards update is effective with its March 31, 2019 quarterly report on Form 10-Q. The Corporation is currently evaluating the impact of the adoption of ASC Update 2016-02 on its consolidated financial statements.

In March 2016, the FASB issued ASC Update 2016-09, "Stock Compensation: Improvements to Employee Share-Based Payment Accounting." The purpose of this standards update is to simplify several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liability, and classification on the statement of cash flows. ASC Update 2016-09 is effective for interim and annual reporting periods beginning after December 15, 2016. Early application is permitted. For the Corporation, this standards update is effective with its March 31, 2017 quarterly report on Form 10-Q. The Corporation is currently evaluating the impact of the adoption of ASC Update 2016-09 on its consolidated financial statements.

As of March 31, 2016 and December 31, 2015, there were $47.8 million and $50.0 million, respectively, of impaired loans that did not have a related allowance for loan loss. The estimated fair values of the collateral securing these loans exceeded their carrying amount, or they were previously charged down to realizable collateral values. Accordingly, no specific valuation allowance was considered to be necessary.

The following is a summary of the Corporation's internal risk rating categories:

• Pass: These loans do not currently pose undue credit risk and can range from the highest to average quality, depending on the degree of potential risk.

• Special Mention: These loans constitute an undue and unwarranted credit risk, but not to a point of justifying a classification of substandard. Loans in this category are currently acceptable, but are nevertheless potentially weak.

• Substandard or Lower: These loans are inadequately protected by current sound worth and paying capacity of the borrower. There exists a well-defined weakness or weaknesses that jeopardize the normal repayment of the debt.

The risk rating process allows management to identify credits that potentially carry more risk in a timely manner and to allocate resources to managing troubled accounts. The Corporation believes that internal risk ratings are the most relevant credit quality indicator for the class segments presented above. The migration of loans through the various internal risk rating categories is a significant component of the allowance for credit loss methodology, which bases the probability of default on this migration. Assigning risk ratings involves judgment. Risk ratings are initially assigned to loans by loan officers and are reviewed on a regular basis by credit administration staff. The Corporation's loan review officers provide a separate assessment of risk rating accuracy. Ratings may be changed based on the ongoing monitoring procedures performed by loan officers or credit administration staff, or if specific loan review activities identify a deterioration or an improvement in the loan.

The Corporation does not assign internal risk ratings to smaller balance, homogeneous loans, such as home equity, residential mortgage, consumer, lease receivables and construction loans to individuals secured by residential real estate. For these loans, the most relevant credit quality indicator is delinquency status. The migration of loans through the various delinquency status categories is a significant component of the allowance for credit losses methodology for those loans, which bases the probability of default on this migration.

The following table presents a summary of delinquency and non-performing status for home equity, real estate - residential mortgages, construction loans to individuals and consumer, leasing and other loans by class segment:
