NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

March 31, 2018

The terms “FNB,” “the Corporation,” “we,” “us” and “our” throughout this Report mean F.N.B. Corporation and our consolidated subsidiaries, unless the context indicates that we refer only to the parent company, F.N.B. Corporation. When we refer to "FNBPA" in this Report, we mean our only bank subsidiary, First National Bank of Pennsylvania, and its subsidiaries.

NATURE OF OPERATIONS

F.N.B. Corporation, headquartered in Pittsburgh, Pennsylvania, is a diversified financial services company operating in eight states. Through FNBPA, we have over 150 years of serving the financial and banking needs of our customers. We hold a significant retail deposit market share in attractive markets including: Pittsburgh, Pennsylvania; Baltimore, Maryland; Cleveland, Ohio; and Charlotte, Raleigh-Durham and the Piedmont Triad (Winston-Salem, Greensboro and High Point) in North Carolina. As of March 31, 2018 , we had 417 banking offices throughout Pennsylvania, Ohio, Maryland, West Virginia, North Carolina and South Carolina. We provide a full range of commercial banking, consumer banking and wealth management solutions through our subsidiary network which is led by our largest affiliate, FNBPA. Commercial banking solutions include corporate banking, small business banking, investment real estate financing, business credit, capital markets and lease financing. Consumer banking provides a full line of consumer banking products and services including deposit products, mortgage lending, consumer lending and a complete suite of mobile and online banking services. Wealth management services include fiduciary and brokerage services, asset management, private banking and insurance. We also operate Regency Finance Company, which had 77 consumer finance offices in Pennsylvania, Ohio, Kentucky and Tennessee as of March 31, 2018 .

NOTE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

Our accompanying Consolidated Financial Statements and these Notes to the Financial Statements include subsidiaries in which we have a controlling financial interest. We own and operate FNBPA, First National Trust Company, First National Investment Services Company, LLC, F.N.B. Investment Advisors, Inc., First National Insurance Agency, LLC, Regency, Bank Capital Services, LLC and F.N.B. Capital Corporation, LLC, and include results for each of these entities in the accompanying Consolidated Financial Statements.

The accompanying Consolidated Financial Statements include all adjustments that are necessary, in the opinion of management, to fairly reflect our financial position and results of operations in accordance with U.S. generally accepted accounting principles. All significant intercompany balances and transactions have been eliminated. Certain prior period amounts have been reclassified to conform to the current period presentation. Such reclassifications had no impact on our net income and stockholders’ equity. Events occurring subsequent to the date of the March 31, 2018 Balance Sheet have been evaluated for potential recognition or disclosure in the Consolidated Financial Statements through the date of the filing of the Consolidated Financial Statements with the Securities and Exchange Commission.

Certain information and Note disclosures normally included in Consolidated Financial Statements prepared in accordance with GAAP have been condensed or omitted pursuant to the rules and regulations of the SEC. The interim operating results are not necessarily indicative of operating results FNB expects for the full year. These interim unaudited Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements and Notes thereto included in FNB’s 2017 Annual Report on Form 10-K filed with the SEC on February 28, 2018 . For a detailed description of our significant accounting policies, see Note 1 "Summary of Significant Accounting Policies" in the 2017 Form 10-K. The accounting policies presented below have been added or amended for newly material items or the adoption of new accounting standards.

Use of Estimates

Our accounting and reporting policies conform with GAAP. The preparation of Financial Statements in conformity with GAAP requires us to make estimates and assumptions that affect the amounts reported in the Consolidated Financial Statements and accompanying Notes. Actual results could materially differ from those estimates. Material estimates that are particularly

Table of Contents

susceptible to significant changes include the allowance for credit losses, accounting for acquired loans, fair value of financial instruments, goodwill and other intangible assets, income taxes and deferred tax assets and litigation.

Revenue from Contracts with Customers

We earn certain revenues from contracts with customers. These revenues are recognized when control of the promised services is transferred to the customers in an amount that reflects the consideration we expect to be entitled to in an exchange for those services.

In determining the appropriate revenue recognition for our contracts with customers, we consider whether the contract has commercial substance and is approved by both parties with identifiable contractual rights, payment terms, and the collectability of consideration is probable. Generally, we satisfy our performance obligations upon the completion of services at the amount to which we have the right to invoice or charge under contracts with an original expected duration of one year or less. We apply this guidance on a portfolio basis to contracts with similar characteristics and for which we believe the results would not differ materially from applying this guidance to individual contracts.

Our services provided under contracts with customers are transferred at the point in time when the services are rendered. Generally, we do not defer incremental direct costs to obtain contracts with customers that would be amortized in one year or less under the practical expedient. These costs are recognized as expense, primarily salary and benefit expense, in the period incurred.

Deposit Services . We recognize revenue on deposit services based on published fees for services provided. Demand and savings deposit customers have the right to cancel their depository arrangements and withdraw their deposited funds at any time without prior notice. When services involve deposited funds that can be retrieved by customers without penalties, we consider the service contract term to be day-to-day, where each day represents the renewal of the contract. The contract does not extend beyond the services performed and revenue is recognized at the end of the contract term (daily) as the performance obligation is satisfied.

No deposit services fees exist for long-term deposit products beyond early withdrawal penalties, which are earned on these products at the time of early termination.

Revenue from deposit services fees are reduced where we have a history of waived or reduced fees by customer request or due to a customer service issue, by historical experience, or another acceptable method in the same period as the related revenues. Revenues from deposit services are reported in the Consolidated Statements of Income as service charges and in the Community Banking segment as non-interest income.

Wealth Management Services. Wealth advisory and trust services are provided on a month-to-month basis and invoiced as services are rendered. Fees are based on a fixed amount or a scale based on the level of services provided or assets under management. The customer has the right to terminate their services agreement at any time. We determine the value of services performed based on the fee schedule in effect at the time the services are performed. Revenues from wealth advisory and trust services are reported in the Consolidated Statements of Income as trust services and securities commissions and fees, and in the Wealth segment as non-interest income.

Insurance Services. Insurance services include full-service insurance brokerage services offering numerous lines of commercial and personal insurance through major carriers to businesses and individuals within our geographic markets. We recognize revenue on insurance contracts in effect based on contractually specified commission payments on premiums that are paid by the customer to the insurance carrier. Contracts are cancellable at any time and we have no performance obligation to the customers beyond the time the insurance is placed into effect. Revenues from insurance services are reported in the Consolidated Statements of Income as insurance commissions and fees, and in the Insurance segment as non-interest income.

Debt Securities

Debt securities comprise a significant portion of our Consolidated Balance Sheets. Such securities can be classified as trading, HTM or AFS. As of March 31, 2018 and 2017 , we did not hold any trading debt securities.

Debt securities HTM are the securities that management has the positive intent and ability to hold until their maturity. Such securities are carried at cost, adjusted for related amortization of premiums and accretion of discounts through interest income from securities, and subject to evaluation for OTTI.

Table of Contents

Debt securities that are not classified as trading or HTM are classified as AFS. Such securities are carried at fair value with net unrealized gains and losses deemed to be temporary and OTTI attributable to non-credit factors reported separately as a component of other comprehensive income, net of tax.

We evaluate our debt securities in a loss position for OTTI on a quarterly basis at the individual security level based on our intent to sell. If we intend to sell the debt security or it is more likely than not we will be required to sell the security before recovery of its amortized cost basis, OTTI must be recognized in earnings equal to the entire difference between the investments’ amortized cost basis and its fair value. If we do not intend to sell the debt security and it is not more likely than not that we will be required to sell the security before recovery of its amortized cost basis, OTTI must be separated into the amount representing credit loss and the amount related to all other market factors. The amount related to credit loss will be recognized in earnings. The amount related to other market factors will be recognized in other comprehensive income, net of applicable taxes.

We perform our OTTI evaluation process in a consistent and systematic manner and include an evaluation of all available evidence. This process considers factors such as length of time and anticipated recovery period of the impairment, recent events specific to the issuer and recent experience regarding principal and interest payments.

Low Income Housing Tax Credit (LIHTC) Partnerships

We invest in various affordable housing projects that qualify for LIHTCs. The net investments are recorded in other assets on the Consolidated Balance Sheets. These investments generate a return through the realization of federal tax credits. We use the proportional amortization method to account for a majority of our investments in these entities. LIHTCs that do not meet the requirements of the proportional amortization method are recognized using the equity method. Our net investment in LIHTCs was $26.1 million and $20.9 million at March 31, 2018 and December 31, 2017 , respectively. Our unfunded commitments in LIHTCs were $60.1 million and $67.2 million at March 31, 2018 and December 31, 2017 , respectively.

NOTE 2. NEW ACCOUNTING STANDARDS

Retirement Benefits
ASU 2017-07, Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost	This Update requires that an employer disaggregate the service cost component from the other components of net benefit cost. The amendments also provide explicit guidance on how to present the service cost component and the other components of net benefit cost in the income statement and allows only the service cost component of net benefit cost to be eligible for capitalization.	January 1, 2018	We adopted this Update in the first quarter of 2018 by a retrospective transition method. The adoption of this Update did not have a material effect on our Consolidated Financial Statements.
Statement of Cash Flows

Credit Losses
ASU 2016-13 , Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments	This Update replaces the current incurred loss impairment methodology with a methodology that reflects current expected credit losses (commonly referred to as CECL) for most financial assets measured at amortized cost and certain other instruments, including loans, HTM debt securities, net investments in leases and off-balance sheet credit exposures. CECL requires loss estimates for the remaining life of the financial asset at the time the asset is originated or acquired, considering historical experience, current conditions and reasonable and supportable forecasts. In addition, the Update will require the use of a modified AFS debt security impairment model and eliminate the current accounting for purchased credit impaired loans and debt securities.	January 1, 2020 Early adoption is permitted for fiscal years beginning after December 15, 2018	This Update is to be applied using a cumulative-effect adjustment to retained earnings. The CECL model is a significant change from existing GAAP and may result in a material change to our accounting for financial instruments. We are reviewing our business processes, information systems and controls to support recognition and disclosures under this Update. This review includes an assessment of our existing credit models and the financial statement disclosure requirements. The impact of this Update will be dependent on the portfolio composition, credit quality and economic conditions at the time of adoption.

NOTE 3. MERGERS AND ACQUISITIONS

Yadkin Financial Corporation

On March 11, 2017, we completed our acquisition of YDKN, a bank holding company based in Raleigh, North Carolina. YDKN’s banking affiliate, Yadkin Bank, was merged into FNBPA on March 11, 2017. YDKN’s results of operations have been included in our Consolidated Statements of Income since that date. The acquisition enabled us to enter several North Carolina markets, including Raleigh, Charlotte and the Piedmont Triad, which is comprised of Winston-Salem, Greensboro and High Point. We also completed the core systems conversion activities during the first quarter of 2017.

On the acquisition date, the fair values of YDKN included $6.8 billion in assets, of which there was $5.1 billion in loans, and $5.2 billion in deposits. The acquisition was valued at $1.8 billion based on the acquisition date FNB common stock closing price of $15.97 and resulted in FNB issuing 111,619,622 shares of our common stock in exchange for 51,677,565 shares of YDKN common stock. Under the terms of the merger agreement, shareholders of YDKN received 2.16 shares of FNB common stock for each share of YDKN common stock and cash in lieu of fractional shares. YDKN’s fully vested and outstanding stock options were converted into options to purchase and receive FNB common stock. In conjunction with the acquisition, we assumed a warrant that was issued by YDKN to the UST under the Capital Purchase Program. Based on the exchange ratio, this

Table of Contents

warrant, which expires in 2019, was converted into a warrant to purchase up to 207,320 shares of FNB common stock with an exercise price of $9.63 .

The acquisition of YDKN constituted a business combination and has been accounted for using the acquisition method of accounting, and accordingly, assets acquired, liabilities assumed and consideration exchanged were recorded at estimated fair value on the acquisition date. The determination of estimated fair values required management to make certain estimates about discount rates, future expected cash flows, market conditions, and other future events that are highly subjective in nature and may require adjustments, which can be updated for up to a year following the acquisition. As of March 31, 2018 , all fair values and related adjustments to goodwill have been recorded.

Other-Than-Temporary Impairment

We evaluate our investment securities portfolio for OTTI on a quarterly basis. Impairment is assessed at the individual security level. We consider an investment security impaired if the fair value of the security is less than its cost or amortized cost basis. We did not recognize any OTTI losses on securities for the three months ended March 31, 2018 or 2017 .

States of the U.S. and Political Subdivisions

Our municipal bond portfolio with a carrying amount of $960.2 million as of March 31, 2018 is highly rated with an average entity-specific rating of AA and 100% of the portfolio rated A or better. All of the securities in the municipal portfolio except one are general obligation bonds. Geographically, municipal bonds support our primary footprint as 65% of the securities are from municipalities located throughout Pennsylvania, Ohio, Maryland, North Carolina and South Carolina. The average holding size of the securities in the municipal bond portfolio is $3.0 million . In addition to the strong stand-alone ratings, 62% of the municipalities have some formal credit enhancement insurance that strengthens the creditworthiness of their issue. Management reviews the credit profile of each issuer on a quarterly basis.

Table of Contents

Cash flows expected to be collected on acquired loans are estimated quarterly by incorporating several key assumptions similar to the initial estimate of fair value. These key assumptions include probability of default and the amount of actual prepayments after the acquisition date. Prepayments affect the estimated life of the loans and could change the amount of interest income, and possibly principal expected to be collected. In reforecasting future estimated cash flows, credit loss expectations are adjusted as necessary. Improved cash flow expectations for loans or pools are recorded first as a reversal of previously recorded impairment, if any, and then as an increase in prospective yield when all previously recorded impairment has been recaptured. Decreases in expected cash flows are recognized as impairment through a charge to the provision for credit losses and credit to the allowance for credit losses.

During the three months ended March 31, 2018 , there was an overall improvement in cash flow expectations which resulted in a net reclassification of $64.2 million from the non-accretable difference to accretable yield. This reclassification was $23.1 million for the three months ended March 31, 2017 . The reclassification from the non-accretable difference to the accretable yield results in prospective yield adjustments on the loan pools.

Credit Quality

Management monitors the credit quality of our loan portfolio using several performance measures to do so based on payment activity and borrower performance.

Non-performing loans include non-accrual loans and non-performing TDRs. Past due loans are reviewed on a monthly basis to identify loans for non-accrual status. We place originated loans on non-accrual status and discontinue interest accruals on originated loans generally when principal or interest is due and has remained unpaid for a certain number of days or when the full amount of principal and interest is due and has remained unpaid for a certain number of days, unless the loan is both well secured and in the process of collection. Commercial loans and leases are placed on non-accrual at 90 days, installment loans are placed on non-accrual at 120 days and residential mortgages and consumer lines of credit are generally placed on non-accrual at 180 days, though we may place a loan on non-accrual prior to these past due thresholds as warranted. When a loan is placed on non-accrual status, all unpaid accrued interest is reversed. Non-accrual loans may not be restored to accrual status until all delinquent principal and interest have been paid and the ultimate ability to collect the remaining principal and interest is reasonably assured. The majority of TDRs are loans in which we have granted a concession on the interest rate or the original repayment terms due to the borrower’s financial distress.

(1) Past due information for acquired loans is based on the contractual balance outstanding at March 31, 2018 and December 31, 2017 .

(2) Acquired loans are considered performing upon acquisition, regardless of whether the customer is contractually delinquent, if we can reasonably estimate the timing and amount of expected cash flows on such loans. In these instances, we do not consider acquired contractually delinquent loans to be non-accrual or non-performing and continue to recognize interest income on these loans using the accretion method. Acquired loans are considered non-accrual or non-performing when, due to credit deterioration or other factors, we determine we are no longer able to reasonably estimate the timing and amount of expected cash flows on such loans. We do not recognize interest income on acquired loans considered non-accrual or non-performing.

We utilize the following categories to monitor credit quality within our commercial loan and lease portfolio:

Rating Category	Definition
Pass	in general, the condition of the borrower and the performance of the loan is satisfactory or better
Special Mention	in general, the condition of the borrower has deteriorated, requiring an increased level of monitoring
Substandard	in general, the condition of the borrower has significantly deteriorated and the performance of the loan could further deteriorate if deficiencies are not corrected
Doubtful	in general, the condition of the borrower has significantly deteriorated and the collection in full of both principal and interest is highly questionable or improbable

The use of these internally assigned credit quality categories within the commercial loan and lease portfolio permits management’s use of transition matrices to estimate a quantitative portion of credit risk. Our internal credit risk grading system

Table of Contents

is based on past experiences with similarly graded loans and leases and conforms with regulatory categories. In general, loan and lease risk ratings within each category are reviewed on an ongoing basis according to our policy for each class of loans and leases. Each quarter, management analyzes the resulting ratings, as well as other external statistics and factors such as delinquency, to track the migration performance of the commercial loan and lease portfolio. Loans and leases within the Pass credit category or that migrate toward the Pass credit category generally have a lower risk of loss compared to loans and leases that migrate toward the Substandard or Doubtful credit categories. Accordingly, management applies higher risk factors to Substandard and Doubtful credit categories.

The following tables present a summary of our commercial loans and leases by credit quality category, segregated by loans and leases originated and loans acquired:

Credit quality information for acquired loans is based on the contractual balance outstanding at March 31, 2018 and December 31, 2017 .

We use delinquency transition matrices within the consumer and other loan classes to enable management to estimate a quantitative portion of credit risk. Each month, management analyzes payment and volume activity, Fair Isaac Corporation (FICO) scores and other external factors such as unemployment, to determine how consumer loans are performing.

Loans and leases are designated as impaired when, in the opinion of management, based on current information and events, the collection of principal and interest in accordance with the loan and lease contract is doubtful. Typically, we do not consider loans and leases for impairment unless a sustained period of delinquency (i.e., 90 -plus days) is noted or there are subsequent events that impact repayment probability (i.e., negative financial trends, bankruptcy filings, imminent foreclosure proceedings, etc.). Impairment is evaluated in the aggregate for consumer installment loans, residential mortgages, consumer lines of credit and commercial loan and lease relationships less than $0.5 million based on loan and lease segment loss given default. For commercial loan and lease relationships greater than or equal to $0.5 million , a specific valuation allowance is allocated, if necessary, so that the loan is reported net, at the present value of estimated future cash flows using a market interest rate or at the fair value of collateral if repayment is expected solely from the collateral. Consistent with our existing method of income recognition for loans and leases, interest income on impaired loans, except those classified as non-accrual, is recognized using the accrual method. Impaired loans, or portions thereof, are charged off when deemed uncollectible.

Troubled Debt Restructurings

TDRs are loans whose contractual terms have been modified in a manner that grants a concession to a borrower experiencing financial difficulties. TDRs typically result from loss mitigation activities and could include the extension of a maturity date, interest rate reduction, principal forgiveness, deferral or decrease in payments for a period of time and other actions intended to minimize the economic loss and to avoid foreclosure or repossession of collateral.

Following is a summary of the composition of total TDRs:

(in thousands)	Originated	Acquired	Total
March 31, 2018
Accruing:
Performing	$ 19,525	$ 249	$ 19,774
Non-performing	21,283	3,169	24,452
Non-accrual	10,668	357	11,025
Total TDRs	$ 51,476	$ 3,775	$ 55,251
December 31, 2017
Accruing:
Performing	$ 19,538	$ 266	$ 19,804
Non-performing	20,173	3,308	23,481
Non-accrual	10,472	234	10,706
Total TDRs	$ 50,183	$ 3,808	$ 53,991

TDRs that are accruing and performing include loans that met the criteria for non-accrual of interest prior to restructuring for which we can reasonably estimate the timing and amount of the expected cash flows on such loans and for which we expect to fully collect the new carrying value of the loans. During the three months ended March 31, 2018 , we returned to performing status $1.2 million in restructured residential mortgage loans that have consistently met their modified obligations for more than six months. TDRs that are accruing and non-performing are comprised of consumer loans that have not demonstrated a consistent repayment pattern on the modified terms for more than six months, however it is expected that we will collect all future principal and interest payments. TDRs that are on non-accrual are not placed on accruing status until all delinquent principal and interest have been paid and the ultimate collectability of the remaining principal and interest is reasonably assured. Some loan modifications classified as TDRs may not ultimately result in the full collection of principal and interest, as modified, and may result in potential incremental losses which are factored into the allowance for credit losses.

Table of Contents

Excluding purchased impaired loans, commercial loans over $0.5 million whose terms have been modified in a TDR are generally placed on non-accrual, individually analyzed and measured for estimated impairment based on the fair value of the underlying collateral. Our allowance for credit losses included specific reserves for commercial TDRs and pooled reserves for individually impaired loans under $0.5 million based on loan segment loss given default. Upon default, the amount of the recorded investment in the TDR in excess of the fair value of the collateral, less estimated selling costs, is generally considered a confirmed loss and is charged-off against the allowance for credit losses. The reserve for commercial TDRs included in the allowance for credit losses is presented in the following table:

(in thousands)	March 31, 2018	December 31, 2017
Specific reserves for commercial TDRs	$ 726	$ 95
Pooled reserves for individual commercial loans	519	469

All other classes of loans, which are primarily secured by residential properties, whose terms have been modified in a TDR are pooled and measured for estimated impairment based on the expected net present value of the estimated future cash flows of the pool. Our allowance for credit losses included pooled reserves for these classes of loans of $4.0 million for both March 31, 2018 and December 31, 2017 . Upon default of an individual loan, our charge-off policy is followed accordingly for that class of loan.

NOTE 6. ALLOWANCE FOR CREDIT LOSSES

The allowance for credit losses addresses credit losses inherent in the existing loan and lease portfolio and is presented as a reserve against loans and leases on the Consolidated Balance Sheets. Loan and lease losses are charged off against the allowance for credit losses, with recoveries of amounts previously charged off credited to the allowance for credit losses. Provisions for credit losses are charged to operations based on management’s periodic evaluation of the adequacy of the allowance for credit losses.

Mortgage Loan Servicing

We retain the servicing rights on certain mortgage loans sold. The unpaid principal balance of mortgage loans serviced for others, as of March 31, 2018 and December 31, 2017 , is listed below:

Fair value, beginning of period	$ 32,419		$ 17,546
Fair value, end of period	36,445		26,962

We did not have a valuation allowance for MSRs for any of the periods presented in the table above.

The fair value of MSRs is highly sensitive to changes in assumptions and is determined by estimating the present value of the asset’s future cash flows utilizing market-based prepayment rates, discount rates and other assumptions validated through comparison to trade information, industry surveys and with the use of independent third party appraisals. Changes in prepayment speed assumptions have the most significant impact on the fair value of MSRs. Generally, as interest rates decline, mortgage loan prepayments accelerate due to increased refinance activity, which results in a decrease in the fair value of the MSR and as interest rates increase, mortgage loan prepayments decline, which results in an increase in the fair value of the MSR. Measurement of fair value is limited to the conditions existing and the assumptions utilized as of a particular point in time, and those assumptions may not be appropriate if they are applied at a different time.

Following is a summary of the sensitivity of the fair value of MSRs to changes in key assumptions:

(dollars in thousands) — Weighted average life (months)	March 31, 2018 — 84.5		December 31, 2017 — 80.4
Constant prepayment rate (annualized)	9.1	%	9.9	%
Discount rate	9.9	%	9.9	%
Effect on fair value due to change in interest rates:
+0.25%	$ 1,179		$ 1,737
+0.50%	2,131		3,220
-0.25%	(1,476	)	(1,937	)
-0.50%	(3,237	)	(4,007	)

The sensitivity calculations above are hypothetical and should not be considered to be predictive of future performance. Changes in fair value based on adverse changes in assumptions generally cannot be extrapolated because the relationship of the changes in assumptions to fair value may not be linear. Also, in this table, the effects of an adverse variation in a particular assumption on the fair value of the MSRs is calculated without changing any other assumptions, while in reality, changes in one factor may result in changing another, which may magnify or contract the effect of the change.

SBA-Guaranteed Loan Servicing

Beginning in March 2017, as a result of the YDKN acquisition, we retain the servicing rights on SBA-guaranteed loans sold to investors. The standard sale structure under the SBA Secondary Participation Guaranty Agreement provides for us to retain a portion of the cash flow from the interest payment received on the loan, which is commonly known as a servicing spread. The unpaid principal balance of SBA-guaranteed loans serviced for investors, as of March 31, 2018 and December 31, 2017 , was as follows:

(in thousands)	March 31, 2018	December 31, 2017

The fair value of the SBA servicing rights is compared to the amortized basis. If the amortized basis exceeds the fair value, the asset is considered impaired and is written down to fair value through a valuation allowance on the asset and a charge against SBA income. We had a $0.4 million valuation allowance for SBA servicing rights as of March 31, 2018 .

Total short-term borrowings	$ 3,802,480	$ 3,678,337

Borrowings with original maturities of one year or less are classified as short-term. Securities sold under repurchase agreements are comprised of customer repurchase agreements, which are sweep accounts with next day maturities utilized by larger commercial customers to earn interest on their funds. Securities are pledged to these customers in an amount equal to the outstanding balance.

Following is a summary of long-term borrowings:

(in thousands)	March 31, 2018	December 31, 2017

Other subordinated debt	159,848	160,151
Total long-term borrowings	$ 659,890	$ 668,173

Our banking affiliate has available credit with the FHLB of $7.8 billion , of which $1.9 billion was utilized as of March 31, 2018 . These advances are secured by loans collateralized by residential mortgages, home equity lines of credit, commercial real estate and FHLB stock and are scheduled to mature in various amounts periodically through the year 2021 . Effective interest rates paid on the long-term advances ranged from 1.39% to 4.19% for the three months ended March 31, 2018 and 0.95% to 4.19% for the year ended December 31, 2017 .

The junior subordinated debt is comprised of the debt securities issued by FNB in relation to our unconsolidated subsidiary trusts (collectively, the Trusts), which are unconsolidated variable interest entities, and is included on the balance sheet in long-term borrowings. Since third-party investors are the primary beneficiaries, the Trusts are not consolidated in our financial statements. We record the distributions on the junior subordinated debt issued to the Trusts as interest expense.

NOTE 9. DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES

We are exposed to certain risks arising from both our business operations and economic conditions. We principally manage our exposures to a wide variety of business and operational risks through management of our core business activities. We manage economic risks, including interest rate risk, primarily by managing the amount, source, and duration of our assets and liabilities, and through the use of derivative instruments. Derivative instruments are used to reduce the effects that changes in interest rates may have on net income and cash flows. We also use derivative instruments to facilitate transactions on behalf of our customers.

All derivatives are carried on the Consolidated Balance Sheets at fair value and do not take into account the effects of master netting arrangements we have with other financial institutions. Credit risk is included in the determination of the estimated fair value of derivatives. Derivative assets are reported in the Consolidated Balance Sheets in other assets and derivative liabilities are reported in the Consolidated Balance Sheets in other liabilities. Changes in fair value are recognized in earnings except for certain changes related to derivative instruments designated as part of a cash flow hedging relationship.

The following table presents notional amounts and gross fair values of our derivative assets and derivative liabilities which are not offset in the balance sheet.

Beginning in the first quarter of 2017, certain derivative exchanges have enacted a rule change which in effect results in the legal characterization of variation margin payments for certain derivative contracts as settlement of the derivatives mark-to-market exposure and not collateral. This rule change became effective for us in the first quarter of 2017. Accordingly, we have changed our reporting of certain derivatives to record variation margin on trades cleared through exchanges that have adopted the rule change as settled where we had previously recorded cash collateral. The daily settlement of the derivative exposure does not change or reset the contractual terms of the instrument.

Derivatives Designated as Hedging Instruments under GAAP

Interest Rate Contracts. We entered into interest rate derivative agreements to modify the interest rate characteristics of certain commercial loans and five of our FHLB advances from variable rate to fixed rate in order to reduce the impact of changes in future cash flows due to market interest rate changes. These agreements are designated as cash flow hedges (i.e., hedging the exposure to variability in expected future cash flows). The effective portion of the derivative’s gain or loss is initially reported as a component of other comprehensive income and subsequently reclassified into earnings in the same line item associated with the forecasted transaction when the forecasted transaction affects earnings. Any ineffective portion of the gain or loss is reported in earnings immediately.

Following is a summary of key data related to interest rate contracts:

(in thousands)	March 31, 2018	December 31, 2017
Notional amount	$ 705,000	$ 705,000
Fair value included in other assets	—	228
Fair value included in other liabilities	3,662	1,982

Table of Contents

The following table shows amounts reclassified from accumulated other comprehensive income for the three months ended March 31, 2018 :

(in thousands) — Reclassified from AOCI to interest income	Total — $ 93		Net of Tax — $ 73
Reclassified from AOCI to interest expense	(129	)	(102	)

As of March 31, 2018 , the maximum length of time over which forecasted interest cash flows are hedged is 5 years. In the twelve months that follow March 31, 2018 , we expect to reclassify from the amount currently reported in AOCI net derivative gains of $3.2 million ( $2.5 million net of tax), in association with interest on the hedged loans and FHLB advances. This amount could differ from amounts actually recognized due to changes in interest rates, hedge de-designations, and the addition of other hedges subsequent to March 31, 2018 .

There were no components of derivative gains or losses excluded from the assessment of hedge effectiveness related to these cash flow hedges. For the three months ended March 31, 2018 and 2017 , there was no hedge ineffectiveness. Also, during the three months ended March 31, 2018 and 2017 , there were no gains or losses from cash flow hedge derivatives reclassified to earnings because it became probable that the original forecasted transactions would not occur.

Derivatives Not Designated as Hedging Instruments under GAAP

Interest Rate Swaps. We enter into interest rate swap agreements to meet the financing, interest rate and equity risk management needs of qualifying commercial loan customers. These agreements provide the customer the ability to convert from variable to fixed interest rates. The credit risk associated with derivatives executed with customers is essentially the same as that involved in extending loans and is subject to normal credit policies and monitoring. Swap derivative transactions with customers are not subject to enforceable master netting arrangements and are generally secured by rights to non-financial collateral, such as real and personal property.

We enter into positions with a derivative counterparty in order to offset our exposure on the fixed components of the customer interest rate swap agreements. We seek to minimize counterparty credit risk by entering into transactions only with high-quality financial dealer institutions. These arrangements meet the definition of derivatives, but are not designated as hedging instruments under ASC 815, Derivatives and Hedging.

Following is a summary of key data related to interest rate swaps:

(in thousands)	March 31, 2018	December 31, 2017
Notional amount	$ 4,844,472	$ 4,490,884
Fair value included in other assets	18,657	28,402
Fair value included in other liabilities	47,904	26,902

The interest rate swap agreement with the loan customer and with the counterparty is reported at fair value in other assets and other liabilities on the Consolidated Balance Sheets with any resulting gain or loss recorded in current period earnings as other income or other expense.

Interest Rate Lock Commitments . Interest rate lock commitments represent an agreement to extend credit to a mortgage loan borrower, or an agreement to purchase a loan from a third-party originator, whereby the interest rate on the loan is set prior to funding. We are bound to fund the loan at a specified rate, regardless of whether interest rates have changed between the commitment date and the loan funding date, subject to the loan approval process. The borrower is not obligated to perform under the commitment. As such, outstanding IRLCs subject us to interest rate risk and related price risk during the period from the commitment to the borrower through the loan funding date, or commitment expiration. The IRLCs generally range between 30 to 270 days. The IRLCs are reported at fair value in other assets and other liabilities on the Consolidated Balance Sheets with any resulting gain or loss recorded in current period earnings as mortgage banking operations income.

Forward Delivery Commitments . Forward delivery commitments on mortgage-backed securities are used to manage the interest rate and price risk of our IRLCs and mortgage loan held for sale inventory by fixing the forward sale price that will be realized upon sale of the mortgage loans into the secondary market. Historical commitment-to-closing ratios are considered to estimate the quantity of mortgage loans that will fund within the terms of the IRLCs. The forward delivery contracts are reported at fair

We purchase and sell credit protection under risk participation agreements to share with other counterparties some of the credit exposure related to interest rate derivative contracts or to take on credit exposure to generate revenue. We will make/receive payments under these agreements if a customer defaults on their obligation to perform under certain derivative swap contracts.

Risk participation agreements sold with notional amounts totaling $128.7 million as of March 31, 2018 have remaining terms ranging from three months to nine years. Under these agreements, our maximum exposure assuming a customer defaults on their obligation to perform under certain derivative swap contracts with third parties would be $0.06 million and $0.1 million at March 31, 2018 and December 31, 2017 , respectively. The fair values of risk participation agreements purchased and sold were $0.02 million and $(0.06) million , respectively, at December 31, 2018 and $0.04 million and $(0.1) million , respectively at December 31, 2017 .

Counterparty Credit Risk

We are party to master netting arrangements with most of our swap derivative dealer counterparties. Collateral, usually marketable securities and/or cash, is exchanged between FNB and our counterparties, and is generally subject to thresholds and transfer minimums. For swap transactions that require central clearing, we post cash to our clearing agency. Collateral positions are settled or valued daily, and adjustments to amounts received and pledged by us are made as appropriate to maintain proper collateralization for these transactions.

Certain master netting agreements contain provisions that, if violated, could cause the counterparties to request immediate settlement or demand full collateralization under the derivative instrument. If we had breached our agreements with our derivative counterparties we would be required to settle our obligations under the agreements at the termination value and would be required to pay an additional $0.6 million and $0.9 million as of March 31, 2018 and December 31, 2017 , respectively, in excess of amounts previously posted as collateral with the respective counterparty.

NOTE 10. COMMITMENTS, CREDIT RISK AND CONTINGENCIES

We have commitments to extend credit and standby letters of credit that involve certain elements of credit risk in excess of the amount stated in the Consolidated Balance Sheets. Our exposure to credit loss in the event of non-performance by the customer is represented by the contractual amount of those instruments. The credit risk associated with commitments to extend credit and standby letters of credit is essentially the same as that involved in extending loans and leases to customers and is subject to normal credit policies. Since many of these commitments expire without being drawn upon, the total commitment amounts do not necessarily represent future cash flow requirements.

Following is a summary of off-balance sheet credit risk information:

(in thousands)	March 31, 2018	December 31, 2017
Commitments to extend credit	$ 7,097,958	$ 6,957,822
Standby letters of credit	136,661	132,904

At March 31, 2018 , funding of 76.4% of the commitments to extend credit was dependent on the financial condition of the customer. We have the ability to withdraw such commitments at our discretion. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Based on management’s credit evaluation of the customer, collateral may be deemed necessary. Collateral requirements vary and may include accounts receivable, inventory, property, plant and equipment and income-producing commercial properties.

Standby letters of credit are conditional commitments issued by us that may require payment at a future date. The credit risk involved in issuing letters of credit is actively monitored through review of the historical performance of our portfolios.

In addition to the above commitments, subordinated notes issued by FNB Financial Services, LP, a wholly-owned finance subsidiary, are fully and unconditionally guaranteed by FNB. These subordinated notes are included in the summaries of short-term borrowings and long-term borrowings in Note 8.

Other Legal Proceedings

In the ordinary course of business, we are routinely named as defendants in, or made parties to, pending and potential legal actions. Also, as regulated entities, we are subject to governmental and regulatory examinations, information-gathering requests, and may be subject to investigations and proceedings (both formal and informal). Such threatened claims, litigation, investigations, regulatory and administrative proceedings typically entail matters that are considered incidental to the normal conduct of business. Claims for significant monetary damages may be asserted in many of these types of legal actions, while claims for disgorgement, restitution, penalties and/or other remedial actions or sanctions may be sought in regulatory matters. In these instances, if we determine that we have meritorious defenses, we will engage in an aggressive defense. However, if management determines, in consultation with counsel, that settlement of a matter is in the best interest of our Company and our shareholders, we may do so. It is inherently difficult to predict the eventual outcomes of such matters given their complexity and the particular facts and circumstances at issue in each of these matters. However, on the basis of current knowledge and understanding, and advice of counsel, we do not believe that judgments, sanctions, settlements or orders, if any, that may arise from these matters (either individually or in the aggregate, after giving effect to applicable reserves and insurance coverage) will have a material adverse effect on our financial position or liquidity, although they could have a material effect on net income in a given period.

In view of the inherent unpredictability of outcomes in litigation and governmental and regulatory matters, particularly where (i) the damages sought are indeterminate, (ii) the proceedings are in the early stages, or (iii) the matters involve novel legal theories or a large number of parties, as a matter of course, there is considerable uncertainty surrounding the timing or ultimate resolution of litigation and governmental and regulatory matters, including a possible eventual loss, fine, penalty, business or adverse reputational impact, if any, associated with each such matter. In accordance with applicable accounting guidance, we establish accruals for litigation and governmental and regulatory matters when those matters proceed to a stage where they present loss contingencies that are both probable and reasonably estimable. In such cases, there may be a possible exposure to loss in excess of any amounts accrued. We will continue to monitor such matters for developments that could affect the amount of the accrual, and will adjust the accrual amount as appropriate. If the loss contingency in question is not both probable and reasonably estimable, we do not establish an accrual and the matter will continue to be monitored for any developments that would make the loss contingency both probable and reasonably estimable. We believe that our accruals for legal proceedings

are appropriate and, in the aggregate, are not material to our consolidated financial position, although future accruals could have a material effect on net income in a given period.

NOTE 11. STOCK INCENTIVE PLANS

Restricted Stock

We issue restricted stock awards, consisting of both restricted stock and restricted stock units, to key employees under our Incentive Compensation Plan (Plan). We issue time-based awards and performance-based awards under this Plan, both of which are based on a three -year vesting period. The grant date fair value of the time-based awards is equal to the price of our common stock on the grant date. The fair value of the performance-based awards is based on a Monte-Carlo simulation valuation of our common stock as of the grant date. The assumptions used for this valuation include stock price volatility, risk-free interest rate and dividend yield.

For performance-based restricted stock awards granted, the recipients will earn shares, totaling between 0% and 175% of the number of units issued, based on our total stockholder return relative to a specified peer group of financial institutions over the three -year period. These market-based restricted stock units are included in the table below as if the recipients earned shares equal to 100% of the units issued, regardless of the actual vesting percentages.

As of March 31, 2018 , we had available up to 2,636,450 shares of common stock to issue under this Plan.

The unvested restricted stock awards are eligible to receive cash dividends or dividend equivalents which are ultimately used to purchase additional shares of stock and are subject to forfeiture if the requisite service period is not completed or the specified performance criteria are not met. These awards are subject to certain accelerated vesting provisions upon retirement, death, disability or in the event of a change of control as defined in the award agreements.

The following table summarizes the activity relating to restricted stock awards during the periods indicated:

	Three Months Ended March 31,

Stock Options

All outstanding stock options were assumed from acquisitions and are fully vested. Upon consummation of our acquisitions, all outstanding stock options issued by the acquired companies were converted into equivalent FNB stock options. We issue shares of treasury stock or authorized but unissued shares to satisfy stock options exercised.

The following table summarizes the activity relating to stock options during the periods indicated:

	Three Months Ended March 31,

Options outstanding and exercisable at end of period	559,378		8.03	919,104		8.77

The intrinsic value of outstanding and exercisable stock options at March 31, 2018 was $3.0 million . The aggregate intrinsic value represents the amount by which the fair value of underlying stock exceeds the option exercise price.

NOTE 12. RETIREMENT PLANS

Our subsidiaries participate in a qualified 401(k) defined contribution plan under which employees may contribute a percentage of their salary. Employees are eligible to participate upon their first day of employment. Under this plan, we match 100% of the first six percent that the employee defers. Additionally, we may provide a performance-based company contribution of up to three percent if we exceed annual financial goals. Our contribution expense is presented in the following table:

(in thousands)	Three Months Ended March 31, — 2018	2017
401(k) contribution expense	$ 3,610	$ 2,767

We also sponsor an Employee Retirement Income Security Act of 1974 (ERISA) Excess Lost Match Plan for certain officers. This plan provides retirement benefits equal to the difference, if any, between the maximum benefit allowable under the Internal Revenue Code and the amount that would have been provided under the qualified 401(k) defined contribution plan, if no limits were applied.

NOTE 13. INCOME TAXES

The TCJA includes several changes to existing U.S. tax laws that impact us, most notably a reduction of the U.S. corporate income tax rate from 35% to 21% , which became effective January 1, 2018. We recognized the initial income tax effects of the TCJA in our 2017 financial statements in accordance with Staff Accounting Bulletin No. 118, which provides SEC staff guidance for the application of ASC 740, Income Taxes, in the reporting period in which the TCJA was signed into law. As such, our financial results reflect the income tax effects of the TCJA for which the accounting under ASC 740 is complete, as well as for provisional amounts for those specific income tax effects under ASC 740 that are incomplete, but a reasonable estimate could be determined. We did not identify any items for which the income tax effects of the TCJA have not been completed and a reasonable estimate could not be determined as of December 31, 2017, which was our first reporting date after the TCJA enactment. Examples of unavailable or unanalyzed information for which we have provisional estimates include deferred taxes related to depreciation (including lease financing), partnership earnings, and realized built-in losses from a prior acquisition. These estimates are subject to change as additional data is gathered, as interpretations and guidance are received, and as the final analyses are completed. The measurement period ends when we have analyzed the information necessary to finalize our accounting, but cannot extend beyond one year from the TCJA enactment date.

Income Tax Expense

Federal and state income tax expense and the statutory tax rate and the actual effective tax rate consist of the following:

(in thousands)	Three Months Ended March 31, — 2018		2017
Current income taxes:
Federal taxes	$ 17,700		$ 6,688
State taxes	1,704		499
Total current income taxes	19,404		7,187
Deferred income taxes:
Federal taxes	1,902		1,690
State taxes	(38	)	(2,393	)
Total deferred income taxes	1,864		(703	)
Total income taxes	$ 21,268		$ 6,484
Statutory tax rate	21.0	%	35.0	%
Effective tax rate	19.7	%	22.0	%

The effective tax rate for the quarter ended March 31, 2018 under the 21% TCJA statutory federal tax rate was 19.7% . The effective tax rate for the quarter ended March 31, 2017 under the former 35% statutory federal tax rate was 22.0% . The effective tax rate for the quarter ended March 31, 2018 was lower than the statutory tax rate of 21% due to tax benefits resulting

Table of Contents

from tax-exempt income on investments, loans, tax credits and income from BOLI. The lower effective tax rate for the quarter ended March 31, 2017 primarily related to merger expenses from the Yadkin acquisition.

In the fourth quarter of 2017, we elected to change our accounting policy under ASU 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220) to reclassify the income tax effects related to the TCJA from AOCI to retained earnings.

Deferred Income Taxes

Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and tax purposes. Deferred tax assets and liabilities are measured based on the enacted tax rates that will apply in the years in which the temporary differences are expected to be recovered or paid. As such, during December 2017, we remeasured our deferred tax assets and liabilities as a result of the passage of the TCJA. The primary impact of this remeasurement was a reduction in deferred tax assets and liabilities in connection with the reduction of the U.S. corporate income tax rate from 35% to 21% .

NOTE 14. OTHER COMPREHENSIVE INCOME

The following table presents changes in AOCI, net of tax, by component:

(in thousands)	Unrealized Net Losses on Debt Securities Available for Sale		Unrealized Net Gains (Losses) on Derivative Instruments		Unrecognized Pension and Postretirement Obligations		Total

The amounts reclassified from AOCI related to debt securities available for sale are included in net securities gains on the Consolidated Income Statements, while the amounts reclassified from AOCI related to derivative instruments are included in interest income on loans and leases on the Consolidated Income Statements.

The tax (benefit) expense amounts reclassified from AOCI in connection with the debt securities available for sale and derivative instruments reclassifications are included in income taxes on the Consolidated Statements of Income.

NOTE 15. EARNINGS PER COMMON SHARE

Basic earnings per common share is calculated by dividing net income available to common stockholders by the weighted average number of shares of common stock outstanding net of unvested shares of restricted stock.

Diluted earnings per common share is calculated by dividing net income available to common stockholders by the weighted average number of shares of common stock outstanding, adjusted for the dilutive effect of potential common shares issuable for stock options, warrants and restricted shares, as calculated using the treasury stock method. Adjustments to the weighted average number of shares of common stock outstanding are made only when such adjustments dilute earnings per common share.

Table of Contents

The following table sets forth the computation of basic and diluted earnings per common share:

We review fair value hierarchy classifications on a quarterly basis. Changes in the observability of the valuation attributes may result in reclassification of certain financial assets or liabilities. Such reclassifications are reported as transfers in/out of Level 3 at fair value at the beginning of the period in which the changes occur. There were no transfers of assets or liabilities between the hierarchy levels during the first three months of 2018. During the first quarter of 2017, we acquired $12.0 million in other debt securities from YDKN that are measured at Level 3. These securities were sold during the second quarter of 2017. During the first three months of 2017, we transferred equity securities totaling $0.6 million from Level 3 to Level 2, as a result of increased trading activity relating to these securities.

For the three months ended March 31, 2018 , we recorded in earnings $0.5 million of unrealized gains relating to the adoption of ASU 2016-01 and market value adjustments on marketable equity securities. These unrealized gains included in earnings are in the other non-interest income line item in the consolidated statement of income. For the three months ended March 31, 2017 , there were no gains or losses included in earnings attributable to the change in unrealized gains or losses relating to assets still held as of those dates. The total realized net securities gains included in earnings are in the net securities gains line item in the Consolidated Statements of Income.

Table of Contents

In accordance with GAAP, from time to time, we measure certain assets at fair value on a non-recurring basis. These adjustments to fair value usually result from the application of the lower of cost or fair value accounting or write-downs of individual assets. Valuation methodologies used to measure these fair value adjustments were described in Note 24 "Fair Value Measurements" in our 2017 Form 10-K. For assets measured at fair value on a non-recurring basis still held at the balance sheet date, the following table provides the hierarchy level and the fair value of the related assets or portfolios:

(in thousands)	Level 1	Level 2	Level 3	Total
March 31, 2018
Impaired loans	$ —	$ 2,032	$ 1,475	$ 3,507
Other real estate owned	—	—	1,621	1,621
Other assets - SBA servicing asset	—	—	5,062	5,062
December 31, 2017
Impaired loans	$ —	$ 2,813	$ 1,297	$ 4,110
Other real estate owned	—	10,513	10,823	21,336
Loans held for sale - SBA	—	—	36,432	36,432
Other assets - SBA servicing asset	—	—	5,058	5,058

Substantially all of the fair value amounts in the table above were estimated at a date during the three months or twelve months ended March 31, 2018 and December 31, 2017 , respectively. Consequently, the fair value information presented is not necessarily as of the period’s end.

Impaired loans measured or re-measured at fair value on a non-recurring basis during the three months ended March 31, 2018 had a carrying amount of $3.5 million , which includes an allocated allowance for credit losses of $3.2 million . The allowance for credit losses includes a provision applicable to the current period fair value measurements of $2.7 million , which was included in the provision for credit losses for the three months ended March 31, 2018 .

OREO with a carrying amount of $2.0 million was written down to $1.6 million , resulting in a loss of $0.4 million , which was included in earnings for the three months ended March 31, 2018 .

Fair Value of Financial Instruments

The following methods and assumptions were used to estimate the fair value of each financial instrument:

Cash and Cash Equivalents, Accrued Interest Receivable and Accrued Interest Payable. For these short-term instruments, the carrying amount is a reasonable estimate of fair value.

Securities. For both securities AFS and securities HTM, fair value equals the quoted market price from an active market, if available, and is classified within Level 1. If a quoted market price is not available, fair value is estimated using quoted market prices for similar securities or pricing models, and is classified as Level 2. Where there is limited market activity or significant valuation inputs are unobservable, securities are classified within Level 3. Under current market conditions, assumptions used to determine the fair value of Level 3 securities have greater subjectivity due to the lack of observable market transactions.

Loans and Leases. The fair value of fixed rate loans and leases is estimated by discounting the future cash flows using the current rates at which similar loans and leases would be made to borrowers with similar credit ratings and for the same remaining maturities less an illiquidity discount, as the fair value measurement represents an exit price from a market participants' viewpoint. The fair value of variable and adjustable rate loans and leases approximates the carrying amount. Due to the significant judgment involved in evaluating credit quality, loans and leases are classified within Level 3 of the fair value hierarchy.

Loan Servicing Rights . For both MSRs and SBA servicing rights, both classified as Level 3 assets, fair value is determined using a discounted cash flow valuation method. These models use significant unobservable inputs including discount rates, prepayment rates and cost to service which have greater subjectivity due to the lack of observable market transactions.

Table of Contents

Derivative Assets and Liabilities. See Note 24 "Fair Value Measurements" to the Consolidated Financial Statements of the Annual Report on Form 10-K for the year ended December 31, 2017 filed with the SEC on February 28, 2018 for a description of valuation methodologies for derivative assets and liabilities measured at fair value.

Deposits. The estimated fair value of demand deposits, savings accounts and certain money market deposits is the amount payable on demand at the reporting date because of the customers’ ability to withdraw funds immediately. The fair value of fixed-maturity deposits is estimated by discounting future cash flows using rates currently offered for deposits of similar remaining maturities.

Short-Term Borrowings. The carrying amounts for short-term borrowings approximate fair value for amounts that mature in 90 days or less. The fair value of subordinated notes is estimated by discounting future cash flows using rates currently offered.

Long-Term Borrowings. The fair value of long-term borrowings is estimated by discounting future cash flows based on the market prices for the same or similar issues or on the current rates offered to us for debt of the same remaining maturities.

Loan Commitments and Standby Letters of Credit. Estimates of the fair value of these off-balance sheet items were not made because of the short-term nature of these arrangements and the credit standing of the counterparties. Also, unfunded loan commitments relate principally to variable rate commercial loans, typically are non-binding, and fees are not normally assessed on these balances.

Nature of Estimates . Many of the estimates presented herein are based upon the use of highly subjective information and assumptions and, accordingly, the results may not be precise. Management believes that fair value estimates may not be comparable to other financial institutions due to the wide range of permitted valuation techniques and numerous estimates which must be made. Further, because the disclosed fair value amounts were estimated as of the balance sheet date, the amounts actually realized or paid upon maturity or settlement of the various financial instruments could be significantly different.

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

Management’s Discussion and Analysis represents an overview of and highlights material changes to our financial condition and results of operations at and for the three -month periods ended March 31, 2018 and 2017 . This Discussion and Analysis should be read in conjunction with the Consolidated Financial Statements and notes thereto contained herein and our 2017 Annual Report on Form 10-K filed with the SEC on February 28, 2018 . Our results of operations for the three months ended March 31, 2018 are not necessarily indicative of results expected for the full year.

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING INFORMATION

A number of statements in this Report may contain forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 including our expectations relative to business and financial metrics, our outlook regarding revenues, expenses, earnings. liquidity, asset quality and statements regarding the impact of technology enhancements and customer and business process improvements.

All forward-looking statements speak only as of the date they are made and are based on information available at that time. We assume no obligation to update forward-looking statements to reflect circumstances or events that occur after the date the forward-looking statements were made or to reflect the occurrence of unanticipated events except as required by federal securities laws. As forward-looking statements involve significant risks and uncertainties, caution should be exercised against placing undue reliance on such statements.

Such forward-looking statements may be expressed in a variety of ways, including the use of future and present tense language expressing expectations or predictions of future financial or business performance or conditions based on current performance and trends. Forward-looking statements are typically identified by words such as, "believe," "plan," "expect," "anticipate," "intend," "outlook," "estimate," "forecast," "will," "should," "project," "goal," and other similar words and expressions. These forward-looking statements involve certain risks and uncertainties. In addition to factors previously disclosed in our reports filed with the SEC, the following factors among others, could cause actual results to differ materially from forward-looking statements or historical performance: changes in asset quality and credit risk; the inability to sustain revenue and earnings growth; changes in interest rates and capital markets; inflation; potential difficulties encountered in expanding into a new and remote geographic market; customer borrowing, repayment, investment and deposit practices; customer disintermediation; the introduction, withdrawal, success and timing of business and technology initiatives; competitive conditions; the inability to realize cost savings or revenues or to implement integration plans and other consequences associated with acquisitions and divestitures; inability to originate and re-sell mortgage loans in accordance with business plans; economic conditions; interruption in or breach of security of our information systems; integrity and functioning of products, information systems and services provided by third party external vendors; changes in tax rules and regulations or interpretations including, but not limited to, the recently enacted Tax Cuts and Jobs Act; changes in accounting policies, standards and interpretations; liquidity risk; changes in asset valuations; and the impact, extent and timing of technological changes, capital management activities, and other actions of the OCC, the FRB, the Consumer Financial Protection Bureau, the FDIC and legislative and regulatory actions and reforms.

Actual results may differ materially from those expressed or implied as a result of these risks and uncertainties, including, but not limited to, the risk factors and other uncertainties described in our Annual Report on Form 10-K for the year ended December 31, 2017 , our subsequent 2018 Quarterly Reports on Form 10-Q's (including the risk factors and risk management discussions) and our other subsequent filings with the SEC, which are available on our corporate website at https://www.fnb-online.com/about-us/investor-relations-shareholder-services. We have included our web address as an inactive textual reference only. Information on our website is not part of this Report.

APPLICATION OF CRITICAL ACCOUNTING POLICIES

A description of our critical accounting policies is included in the Management’s Discussion and Analysis of Financial Condition and Results of Operations section of our 2017 Annual Report on Form 10-K filed with the SEC on February 28, 2018 under the heading “Application of Critical Accounting Policies.” There have been no significant changes in critical accounting policies or the assumptions and judgments utilized in applying these policies since December 31, 2017 .

Table of Contents

USE OF NON-GAAP FINANCIAL MEASURES AND KEY PERFORMANCE INDICATORS

To supplement our Consolidated Financial Statements presented in accordance with GAAP, we use certain non-GAAP financial measures, such as operating net income available to common stockholders, operating earnings per diluted common share, return on average tangible common equity, return on average tangible assets, tangible book value per common share, the ratio of tangible equity to tangible assets, the ratio of tangible common equity to tangible assets, efficiency ratio and net interest margin (FTE) to provide information useful to investors in understanding our operating performance and trends, and to facilitate comparisons with the performance of our peers. Management uses these measures internally to assess and better understand our underlying business performance and trends related to core business activities. The non-GAAP financial measures and key performance indicators we use may differ from the non-GAAP financial measures and key performance indicators other financial institutions use to assess their performance and trends.

These non-GAAP financial measures should be viewed as supplemental in nature, and not as a substitute for or superior to, our reported results prepared in accordance with GAAP. When non-GAAP financial measures are disclosed, the SEC's Regulation G requires: (i) the presentation of the most directly comparable financial measure calculated and presented in accordance with GAAP and (ii) a reconciliation of the differences between the non-GAAP financial measure presented and the most directly comparable financial measure calculated and presented in accordance with GAAP. Reconciliations of non-GAAP operating measures to the most directly comparable GAAP financial measures are included later in this report under the heading “Reconciliation of Non-GAAP Financial Measures and Key Performance Indicators to GAAP.”

Management believes merger expenses are not organic costs to run our operations and facilities. These charges principally represent expenses to satisfy contractual obligations of the acquired entity without any useful benefit to us to convert and consolidate the entity’s records, systems and data onto our platforms and professional fees related to the transaction. These costs are specific to each individual transaction, and may vary significantly based on the size and complexity of the transaction.

Management also considers the remeasurement of the deferred tax assets and liabilities due to the reduction in the corporate tax rate to be a significant item impacting earnings. This tax item is specific to the TCJA that was signed into law in December 2017 which included a reduction of the U.S. corporate income tax rate from 35% to 21%, effective January 1, 2018. We recognized the income tax effects of the net deferred tax asset revaluation in our 2017 financial statements. We believe adjusting for this tax change gives supplemental comparative data from the prior years’ presentation.

For the calculation of net interest margin and efficiency ratio, net interest income amounts are reflected on a fully taxable equivalent basis which adjusts for the tax benefit of income on certain tax-exempt loans and investments using the federal statutory tax rate of 21% in 2018 and 35% in 2017. We use these non-GAAP measures to provide an economic view believed to be the preferred industry measurement for these items and to provide relevant comparison between taxable and non-taxable amounts.

FINANCIAL SUMMARY

Net income available to common stockholders for the first quarter of 2018 was $84.8 million or $0.26 per diluted share. Revenue (net interest income plus non-interest income) of $293.6 million for the first quarter of 2018 reflects continued loan and deposit growth and growth in non-interest income.

FNB made progress towards our long-term strategic goals with strong performances in several key areas during the first quarter of 2018. Our operating net income available to common stockholders and earnings per common share increased 56% and 13% , respectively, compared to the prior year, led by solid growth in loans and in our fee-based businesses. We are well-positioned across our footprint to build on those trends and continue to improve our key operating metrics, as we maintain our focus on delivering earnings per share growth and improved profitability.

Income Statement Highlights ( First quarter of 2018 compared to first quarter of 2017 )

• Net income available to common stockholders was $84.8 million , compared to $21.0 million .

• Operating net income available to common stockholders (non-GAAP) was $84.8 million , compared to $54.4 million .

• Earnings per diluted common share was $0.26 , compared to $0.09 .

• Operating earnings per diluted common share (non-GAAP) was $0.26 , compared to $0.23 .

Table of Contents

• Non-interest income was $67.5 million , compared to $55.1 million , due to the benefit of new markets and the further expansion of business lines, including wealth management, capital markets, mortgage banking and insurance.

• Net interest margin (FTE) (non-GAAP) was 3.39% , compared to 3.35% .

• Non-interest expense was $171.1 million compared to $187.6 million . Non-interest expense, excluding merger-related costs, was $171.1 million , compared to $134.8 million .

• Income tax expense increased $14.8 million , or 228.0% , primarily due to higher 2018 net income partially offset by the lower tax rate in 2018. Income tax expense in the first quarter of 2017 was impacted by merger-related expenses.

• The efficiency ratio (non-GAAP) improved to 55.8% , compared to 57.2% .

• The annualized net charge-offs to total average loans ratio was unchanged at 0.20% .

Balance Sheet Highlights (period-end balances, March 31, 2018 compared to December 31, 2017 , unless otherwise indicated)

RESULTS OF OPERATIONS

Three Months Ended March 31, 2018 Compared to the Three Months Ended March 31, 2017

Net income available to common stockholders for the three months ended March 31, 2018 was $84.8 million or $0.26 per diluted common share, compared to net income available to common stockholders for the three months ended March 31, 2017 of $21.0 million or $0.09 per diluted common share. The first three months of 2017 included merger-related expense of $52.7 million . There were no merger-related expenses recorded during the first three months of 2018 . Operating earnings per diluted common share (non-GAAP) was $0.26 for the first three months of 2018 compared to $0.23 for the three months ended March 31, 2017 . The effective tax rate for the first quarter of 2018 was 19.7% , compared to 22.0% in the year-ago quarter. The current quarter was impacted by the TCJA-enacted 21% statutory rate, while the year-ago quarter was impacted by merger-related expenses. Average diluted common shares outstanding increased 86.5 million shares, or 36.2% , to 325.8 million shares for the first three months of 2018 , primarily as a result of the YDKN acquisition, for which we issued 111.6 million shares. The major categories of the income statement and their respective impact to the increase (decrease) in net income are presented in the following table:

(1) The average balances and yields earned on securities are based on historical cost.

(2) The interest income amounts are reflected on an FTE basis (non-GAAP), which adjusts for the tax benefit of income on certain tax-exempt loans and investments using the federal statutory tax rate of 21% in 2018 and 35% in 2017. The yield on earning assets and the net interest margin are presented on an FTE basis. We believe this measure to be the preferred industry measurement of net interest income and provides relevant comparison between taxable and non-taxable amounts.

(3) Average balances include non-accrual loans. Loans and leases consist of average total loans less average unearned income.

Net Interest Income

For the three months ended March 31, 2018 , net interest income, which comprised 77.0% of revenue compared to 75.8% for the same period in 2017 , was affected by the general level of interest rates, changes in interest rates, the timing of repricing of assets and liabilities, the shape of the yield curve, the level of non-accrual loans and changes in the amount and mix of interest-earning assets and interest-bearing liabilities.

Net interest income on an FTE basis (non-GAAP) increased $52.9 million or 30.0% from $176.3 million for the first three months of 2017 to $229.2 million for the first three months of 2018 . Average interest-earning assets of $27.3 billion increased $6.1 billion or 28.4% and average interest-bearing liabilities of $21.2 billion increased $4.8 billion or 28.9% from the first quarter of 2017 due to the Yadkin acquisition and organic growth in loans and deposits. Our net interest margin FTE (non-GAAP) was 3.39% for the first three months of 2018 , compared to 3.35% for the same period of 2017 , due to a higher interest rate environment, as well as higher purchase accounting accretion. The tax-equivalent adjustments (non-GAAP) to net interest income from amounts reported on our financial statements are shown in the preceding table.

The following table provides certain information regarding changes in net interest income on an FTE basis (non-GAAP) attributable to changes in the average volumes and yields earned on interest-earning assets and the average volume and rates paid for interest-bearing liabilities for the three months ended March 31, 2018 , compared to the three months ended March 31, 2017 :

(1) The amount of change not solely due to rate or volume changes was allocated between the change due to rate and the change due to volume based on the net size of the rate and volume changes.

(2) Interest income amounts are reflected on an FTE basis (non-GAAP) which adjusts for the tax benefit of income on certain tax-exempt loans and investments using the federal statutory tax rate of 21% in 2018 and 35% in 2017. We believe this measure to be the preferred industry measurement of net interest income and provides relevant comparison between taxable and non-taxable amounts.

Interest income on an FTE basis (non-GAAP) of $276.0 million for the first three months of 2018 , increased $77.8 million or 39.3% from the same quarter of 2017 , primarily due to increased interest-earning assets. During the first three months of 2018 and 2017 , we recognized $5.9 million and $3.4 million , respectively, in incremental purchase accounting accretion and cash recoveries on acquired loans; the 2018 increase included $1.8 million of higher incremental purchase accounting accretion and $0.7 million of higher cash recoveries. The increase in interest-earning assets was primarily driven by a $5.0 billion or 30.7% increase in average loans and leases, which reflects the benefit of our expanded banking footprint resulting from the YDKN acquisition and successful sales management, and includes $1.1 billion or 5.5% of organic growth. Additionally, average securities increased $1.0 billion or 20.4% , primarily as a result of the securities portfolio acquired from YDKN and the subsequent repositioning of that portfolio. The yield on average interest-earning assets (non-GAAP) increased 31 basis points

Table of Contents

from the first three months of 2017 to 4.08% for the first three months of 2018 . The 31 basis points increase in earning asset yield was driven by an increase in yields in both investments and loans.

Interest expense of $46.8 million for the first three months of 2018 increased $24.9 million or 113.4% from the same quarter of 2017 due to an increase in rates paid and growth in average interest-bearing liabilities, as interest-bearing deposits and short-term borrowings increased over the same quarter of 2017 . Average interest-bearing deposits increased $3.8 billion or 30.2% , which reflects the benefit of our expanded banking footprint resulting from the YDKN acquisition, including $2.9 billion added at closing of the YDKN acquisition and organic growth in transaction deposits. Average short-term borrowings increased $783.2 million or 24.5% , primarily as a result of increases of $347.3 million in short-term FHLB borrowings and $449.7 million in federal funds purchased. Average long-term borrowings increased $126.2 million or 23.6% , primarily as a result of increases of $47.5 million, $46.8 million and $32.1 million in junior subordinated debt, subordinated debt and long-term FHLB advances, respectively, assumed in the YDKN transaction. Subsequent to the close of the acquisition, we remixed the long–term position based on our funding needs. The rate paid on interest-bearing liabilities increased 35 basis points to 0.89% for the first three months of 2018 , due to the Federal Open Market Committee interest rate increases and changes in the funding mix.

Provision for Credit Losses

The provision for credit losses is determined based on management’s estimates of the appropriate level of allowance for credit losses needed to absorb probable losses inherent in the loan and lease portfolio, after giving consideration to charge-offs and recoveries for the period. The following table presents information regarding the provision for credit losses and net charge-offs:

TABLE 5

(dollars in thousands)	Three Months Ended March 31, — 2018		2017		$ — Change		% — Change
Provision for credit losses:

Net loan charge-offs (annualized) / total average loans and leases	0.20	%	0.20	%
Net originated loan charge-offs (annualized) / total average originated loans and leases	0.29	%	0.25	%

The provision for credit losses of $14.5 million during the first three months of 2018 increased $3.6 million from the same period of 2017 , primarily due to an increase of $3.4 million in the provision for the originated portfolio, which was attributable to higher organic loan growth during the first quarter of 2018 compared to the prior year-ago period, as well as additional reserves that were needed to cover higher charge-offs during the current period. For additional information relating to the allowance and provision for credit losses, refer to the Allowance for Credit Losses section of this Management’s Discussion and Analysis.

Total non-interest income	$ 67,503	$ 55,116	$ 12,387		22.5	%

Total non-interest income increased $12.4 million , to $67.5 million for the first three months of 2018 , a 22.5% increase from the same period of 2017 . The variances in significant individual non-interest income items are further explained in the following paragraphs, with most increases relating at least partially to expanded operations from the acquisition of YDKN in March of 2017.

Service charges on loans and deposits of $30.1 million for the first three months of 2018 increased $5.5 million or 22.4% from the same period of 2017 . The increase was driven by the expanded customer base due to the YDKN acquisition, combined with organic growth in loans and deposit accounts.

Trust services of $6.4 million for the first three months of 2018 increased $0.7 million or 12.2% from the same period of 2017 , primarily driven by strong organic growth activity and improved market conditions. The market value of assets under management increased $715.9 million or 16.9% to $4.9 billion from March 31, 2017 to March 31, 2018 .

Securities commissions and fees of $4.3 million for the first three months of 2018 increased 19.2% from the same period of 2017 . This increase reflects the benefit of expanded operations in North and South Carolina.

Capital markets income of $5.2 million for the first three months of 2018 increased $1.4 million or 35.5% from $3.8 million for 2017 , as we earned more in fees through our commercial loans interest rate swap program, reflecting stronger demand from commercial loan customers to swap floating-rate interest payments for fixed-rate interest payments, enabling those customers to better manage their interest rate risk.

Mortgage banking operations income of $5.5 million for the first three months of 2018 increased $1.7 million or 45.9% from the same period of 2017 . During the first three months of 2018 , we sold $265.0 million of residential mortgage loans, a 98.5% increase compared to $133.5 million for the same period of 2017 . However, sold loan margins have been lower in both retail and correspondent loans due to competitive pressure.

Income from BOLI of $3.3 million for the first three months of 2018 increased $1.1 million or 52.6% from $2.2 million in the same period of 2017 , due to a combination of BOLI policies acquired from YDKN and investing in two new policies during the third and fourth quarters of 2017.

Net securities gains were $2.6 million for the first three months of 2017 . These gains related to the sale of certain acquired YDKN securities after the closing of the acquisition. We did not record any securities gains for the first three months of 2018 .

Other non-interest income was $7.5 million and $3.6 million for the first three months of 2018 and 2017 , respectively. During the first three months of 2018 , dividends on non-marketable equity securities increased by $2.3 million and SBA loan gain on sale and servicing-related income increased $1.4 million compared to the year-ago quarter.

Total non-interest expense	$ 171,083	$ 187,555	$ (16,472	)	(8.8	)%

Total non-interest expense of $171.1 million for the first three months of 2018 decreased $16.5 million , an 8.8% decrease from the same period of 2017 . The variances in the individual non-interest expense items are further explained in the following paragraphs, with most increases relating at least partially to costs associated with expanded operations due to the acquisition of YDKN in March of 2017, offset by merger-related expenses of $52.7 million in the year-ago quarter.

Salaries and employee benefits of $89.3 million for the first three months of 2018 increased $15.7 million or 21.4% from the same period of 2017 , primarily due to employees added in conjunction with the YDKN acquisition, combined with 2017 merit increases and higher benefit costs.

Net occupancy and equipment expense of $30.0 million for the first three months of 2018 increased $9.1 million or 43.2% from the same period of 2017 , primarily due to the YDKN acquisition, and our presence in that new market, and our continued investment in new technology. The increased technology costs include upgrades to meet customer needs via the utilization of electronic delivery channels, such as online and mobile banking, investment in infrastructure to support our larger company and expenditures deemed necessary by management to maintain proficiency and compliance with expanding regulatory requirements.

Amortization of intangibles expense of $4.2 million for the first three months of 2018 increased $1.1 million or 36.2% from the first three months of 2017 , due to the additional core deposit intangibles added as a result of the acquisition of YDKN.

Outside services expense of $14.7 million for the first three months of 2018 increased $1.7 million or 12.9% from the same period of 2017 , primarily due to an increase of $0.7 million in legal expense, combined with various other miscellaneous increases. These increases were driven primarily by the YDKN acquisition.

FDIC insurance of $8.8 million for the first three months of 2018 increased $3.4 million or 64.0% from the same period of 2017 , primarily due to a higher assessment base resulting from merger and acquisition activity combined with an increased rate due to YDKN's construction loan portfolio.

Other non-interest expense was $18.8 million and $13.6 million for the first three months of 2018 and 2017 , respectively. During the first three months of 2018 , business development costs increased by $1.0 million, miscellaneous losses increased by $0.9 million, historic and other tax credit investments expense increased by $0.8 million and marketing expense increased by $0.8 million. These increases were primarily related to the expanded operations in North and South Carolina.

Income Taxes

The following table presents information regarding income tax expense and certain tax rates:

TABLE 8

(dollars in thousands)	Three Months Ended March 31, — 2018	2017
Income tax expense	$ 21,268	$ 6,484
Effective tax rate	19.7 %	22.0 %
Statutory tax rate	21.0 %	35.0 %

Both periods’ tax rates are lower than the federal statutory tax rates of 21% in 2018 and 35% in 2017 , due to the tax benefits primarily resulting from tax-exempt income on investments and loans, tax credits and income from BOLI. The effective tax rate for the first quarter of 2018 was 19.7% , compared to 22.0% in the year-ago quarter. The current quarter was impacted by the TCJA-enacted 21% federal statutory rate while the year-ago quarter was impacted by merger-related expenses.

Non-Performing Assets

Non-performing assets increased $4.4 million , from $138.7 million at December 31, 2017 to $143.1 million at March 31, 2018 . This reflects increases of $3.0 million in non-accrual loans, $1.0 million in TDRs and $0.4 million in OREO. The increase in non-accrual loans is attributable to the migration of two commercial borrowers in the commercial and industrial portfolio, and a few smaller borrowers in the commercial real estate portfolio. The increase in TDRs is related to the modification of a commercial and industrial credit during the first quarter of 2018. The increase in OREO is the result of residential transfers during the first quarter of 2018 outpacing the properties that were sold during this same period.

Allowance for Credit Losses

The allowance for credit losses of $179.2 million at March 31, 2018 increased $3.9 million or 2.2% from December 31, 2017 , primarily in support of growth in originated loans and leases and a small increase in criticized commercial loans. The provision for credit losses during the three months ended March 31, 2018 was $14.5 million , which covered net charge-offs and supported higher organic loan growth. The amount of provision expense that resulted from the aforementioned increase in criticized commercial loans was offset by a provision benefit received through a decline in overall delinquency levels. Net charge-offs were $10.6 million during the three months ended March 31, 2018 . The allowance for credit losses as a percentage of non-performing loans for the total portfolio decreased from 179% as of December 31, 2017 to 175% as of March 31, 2018 , reflecting a slight increase in the level of non-performing loans relative to the increase in the allowance for credit losses during the three -month period.

Following is a summary of supplemental statistical ratios pertaining to our originated loans and leases portfolio. The originated loans and leases portfolio excludes loans acquired at fair value and accounted for in accordance with ASC 805, Business Combinations . Also see Note 5, Loans and Leases, of the Notes to Consolidated Financial Statements (Unaudited).

Deposits

As a bank holding company, our primary source of funds is deposits. These deposits are provided by businesses, municipalities and individuals located within the markets served by our Community Banking subsidiary.

Following is a summary of deposits:

TABLE 13

(in thousands)	March 31, 2018	December 31, 2017	$ Change		% Change
Non-interest-bearing demand	$ 5,748,568	$ 5,720,030	$ 28,538		0.5	%
Interest-bearing demand	9,407,111	9,571,038	(163,927	)	(1.7	)
Savings	2,600,151	2,488,178	111,973		4.5
Certificates and other time deposits	4,741,259	4,620,479	120,780		2.6
Total deposits	$ 22,497,089	$ 22,399,725	$ 97,364		0.4	%

Total deposits increased from December 31, 2017 , primarily as a result of organic growth in certificates and other time deposits. The growth reflects heightened deposit-gathering efforts focused on attracting new customer relationships through targeted promotional interest rates on 13-month, 19-month and 25-month certificates of deposit, combined with deepening relationships with existing customers through internal lead generation efforts. Relationship-based transaction deposits, which are comprised of demand (non-interest-bearing and interest-bearing) and savings accounts (including money market savings), declined in total over this period due somewhat to seasonal outflows. Generating growth in these deposits remains a key focus for us.

Capital Resources and Regulatory Matters

The access to, and cost of, funding for new business initiatives, including acquisitions, the ability to engage in expanded business activities, the ability to pay dividends and the level and nature of regulatory oversight depend, in part, on our capital position.

The assessment of capital adequacy depends on a number of factors such as expected organic growth in the balance sheet, asset quality, liquidity, earnings performance, changing competitive conditions and economic forces. We seek to maintain a strong capital base to support our growth and expansion activities, to provide stability to current operations and to promote public confidence.

In accordance with the terms of our merger with Yadkin Financial Corporation, we issued 111,619,622 shares of our common stock on March 11, 2017.

We have an effective shelf registration statement filed with the SEC. Pursuant to this registration statement, we may, from time to time, issue and sell in one or more offerings any combination of common stock, preferred stock, debt securities, depositary shares, warrants, stock purchase contracts or units.

Capital management is a continuous process, with capital plans and stress testing for FNB and FNBPA updated at least annually. These capital plans include assessing the adequacy of expected capital levels assuming various scenarios by projecting capital needs for a forecast period of 2-3 years beyond the current year. From time to time, we issue shares initially acquired by us as treasury stock under our various benefit plans. We may continue to grow through acquisitions, which can potentially impact our capital position. We may issue additional preferred or common stock in order to maintain our well-capitalized status.

FNB and FNBPA are subject to various regulatory capital requirements administered by the federal banking agencies (see discussion under “Enhanced Regulatory Capital Standards”). Quantitative measures established by regulators to ensure capital adequacy require FNB and FNBPA to maintain minimum amounts and ratios of total, tier 1 and common equity tier 1 capital (as defined in the regulations) to risk-weighted assets (as defined) and minimum leverage ratio (as defined). Failure to meet minimum capital requirements could lead to initiation of certain mandatory, and possibly additional discretionary actions, by regulators that, if undertaken, could have a direct material effect on our Consolidated Financial Statements, dividends and future merger and acquisition activity. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, FNB and FNBPA must meet specific capital guidelines that involve quantitative measures of assets, liabilities and certain off-balance sheet items as calculated under regulatory accounting practices. FNB’s and FNBPA’s capital amounts and classifications are also subject to qualitative judgments by the regulators about components, risk weightings and other factors.

As of March 31, 2018 , the most recent notification from the federal banking agencies categorized FNB and FNBPA as “well-capitalized” under the regulatory framework for prompt corrective action. There are no conditions or events since the notification which management believes have changed this categorization. Our management believes that, as of March 31, 2018 and December 31, 2017 , FNB and FNBPA met all “well-capitalized” requirements to which each of them was subject.

In accordance with Basel III, the implementation of capital requirements is transitional and phases-in from January 1, 2015 through January 1, 2019. The minimum capital requirements plus capital conservation buffer, which are presented for each period above based on the phase-in schedule, represent the minimum requirements needed to avoid limitations on distributions of dividends and certain discretionary bonus payments. Our management believes that FNB and FNBPA will continue to meet all “well-capitalized” requirements after Basel III is completely phased-in.

Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (Dodd-Frank Act)

The Dodd-Frank Act broadly affects the financial services industry by establishing a framework for systemic risk oversight, creating a resolution authority for institutions determined to be systemically important, mandating higher capital and liquidity requirements, requiring banks to pay increased fees to regulatory agencies and containing numerous other provisions aimed at strengthening the sound operation of the financial services sector that significantly change the system of regulatory oversight as described in more detail under Part I, Item 1, “Business - Government Supervision and Regulation” included in our 2017 Annual Report on Form 10-K as filed with the SEC on February 28, 2018 . Many aspects of the Dodd-Frank Act are subject to further rulemaking and will take effect over several years, making it difficult to anticipate the overall financial impact to us or across the financial services industry.

LIQUIDITY

Our goal in liquidity management is to satisfy the cash flow requirements of customers and the operating cash needs of FNB with cost-effective funding. Our Board of Directors has established an Asset/Liability Management Policy in order to guide management in achieving and maintaining earnings performance consistent with long-term goals, while maintaining acceptable levels of interest rate risk, a “well-capitalized” balance sheet and adequate levels of liquidity. Our Board of Directors has also established a Contingency Funding Policy to guide management in addressing stressed liquidity conditions. These policies designate our Asset/Liability Committee as the body responsible for meeting these objectives. The ALCO, which is comprised of members of executive management, reviews liquidity on a continuous basis and approves significant changes in strategies that affect balance sheet or cash flow positions. Liquidity is centrally managed on a daily basis by our Treasury Department.

FNBPA generates liquidity from its normal business operations. Liquidity sources from assets include payments from loans and investments, as well as the ability to securitize, pledge or sell loans, investment securities and other assets. Liquidity sources from liabilities are generated primarily through the banking offices of FNBPA in the form of deposits and customer repurchase agreements. FNB also has access to reliable and cost-effective wholesale sources of liquidity. Short- and long-term funds can be acquired to help fund normal business operations, as well as to serve as contingency funding in the event that we would be faced with a liquidity crisis.

The principal sources of the parent company’s liquidity are its strong existing cash resources plus dividends it receives from its subsidiaries. These dividends may be impacted by the parent’s or its subsidiaries’ capital needs, statutory laws and regulations, corporate policies, contractual restrictions, profitability and other factors. In addition, through one of our subsidiaries, we regularly issue subordinated notes, which are guaranteed by FNB. Cash on hand at the parent has been managed by various strategies over the last few years. These include strong earnings, increasing earnings retention rate and capital actions. The parent’s cash position decreased $3.8 million from $165.7 million at December 31, 2017 to $161.9 million at March 31, 2018 , primarily due to one-time payouts related to the YDKN acquisition.

Management believes our cash levels are appropriate given the current environment. Two metrics that are used to gauge the adequacy of the parent company’s cash position are the LCR and MCH. The LCR is defined as the sum of cash on hand plus projected cash inflows over the next 12 months divided by projected cash outflows over the next 12 months. The MCH is defined as the number of months of corporate expenses and dividends that can be covered by the cash on hand and was impacted by the YDKN acquisition.

The LCR and MCH ratios are presented in the following table:

TABLE 15

(dollars in thousands)	March 31, 2018	December 31, 2017	Internal limit
Liquidity coverage ratio	1.8 times	1.8 times	> 1 time
Months of cash on hand	10.1 months	10.2 months	> 12 months

The MCH ratio fell below our internal limit due to the YDKN acquisition in March 2017. As a result of YDKN, our twelve-month projected dividend payout is estimated at $155 million, an increase of approximately $54 million pre-merger. YDKN did not manage to a similar ratio and held only a minimal amount of cash on hand at their holding company. Our ALCO is evaluating several alternatives, each of which would place the MCH ratio back into policy compliance. Management believes that this policy exception will be cured in 2018.

Our liquidity position has been positively impacted by our ability to generate growth in relationship-based accounts. Organic growth in low-cost transaction deposits was complemented by management’s strategy of heightened deposit gathering efforts during the third and fourth quarters of 2017 focused on attracting new customer relationships and deepening relationships with existing customers through internal lead generation efforts. Total deposits were $22.5 billion at March 31, 2018 , an increase of $97.4 million , or 0.4% from December 31, 2017 . Growth in time deposits was $120.8 million, or 2.6%. Total non-interest demand deposit accounts grew by $28.5 million, or 0.5%, and savings accounts grew by $112.0 million, or 4.5%. These increases were offset by seasonally lower business demand deposit and interest checking balances.

FNBPA has significant unused wholesale credit availability sources that include the availability to borrow from the FHLB, the FRB, correspondent bank lines, access to brokered deposits and multiple other channels. In addition to credit availability, FNBPA also possesses salable unpledged government and agency securities which could be utilized to meet funding needs. The ALCO Policy minimum guideline level for salable unpledged government and agency securities is 3.0%.

Table of Contents

The following table presents certain information relating to FNBPA’s credit availability and salable unpledged securities:

TABLE 16

(dollars in thousands)	March 31, 2018	December 31, 2017
Unused wholesale credit availability	$ 8,227,214	$ 8,189,379

Salable unpledged government and agency securities	$ 2,290,999	$ 2,231,812
Salable unpledged government and agency securities as a % of FNBPA assets	7.3 %	7.2 %

Another metric for measuring liquidity risk is the liquidity gap analysis. The following liquidity gap analysis as of March 31, 2018 compares the difference between our cash flows from existing earning assets and interest-bearing liabilities over future time intervals. Management seeks to limit the size of the liquidity gaps so that sources and uses of funds are reasonably matched in the normal course of business. A reasonably matched position lays a better foundation for dealing with additional funding needs during a potential liquidity crisis. The liquidity gap decreased during the three months as the twelve-month cumulative gap to total assets was (7.0)% and (5.8)% as of March 31, 2018 and December 31, 2017 , respectively. Management calculates this ratio at least quarterly and it is reviewed monthly by ALCO.

In addition, the ALCO regularly monitors various liquidity ratios and stress scenarios of our liquidity position. The stress scenarios forecast that adequate funding will be available even under severe conditions. Management believes we have sufficient liquidity available to meet our normal operating and contingency funding cash needs.

MARKET RISK

Market risk refers to potential losses arising from changes in interest rates, foreign exchange rates, equity prices and commodity prices. We are primarily exposed to interest rate risk inherent in our lending and deposit-taking activities as a financial intermediary. To succeed in this capacity, we offer an extensive variety of financial products to meet the diverse needs of our customers. These products sometimes contribute to interest rate risk for us when product groups do not complement one another. For example, depositors may want short-term deposits, while borrowers desire long-term loans.

Changes in market interest rates may result in changes in the fair value of our financial instruments, cash flows and net interest income. The ALCO is responsible for market risk management which involves devising policy guidelines, risk measures and limits, and managing the amount of interest rate risk and its effect on net interest income and capital. We use derivative financial instruments for interest rate risk management purposes and not for trading or speculative purposes.

Interest rate risk is comprised of repricing risk, basis risk, yield curve risk and options risk. Repricing risk arises from differences in the cash flow or repricing between asset and liability portfolios. Basis risk arises when asset and liability

Table of Contents

portfolios are related to different market rate indexes, which do not always change by the same amount. Yield curve risk arises when asset and liability portfolios are related to different maturities on a given yield curve; when the yield curve changes shape, the risk position is altered. Options risk arises from “embedded options” within asset and liability products as certain borrowers have the option to prepay their loans when rates fall, while certain depositors can redeem their certificates of deposit early when rates rise.

We use an asset/liability model to measure our interest rate risk. Interest rate risk measures we utilize include earnings simulation, EVE and gap analysis. Gap analysis and EVE are static measures that do not incorporate assumptions regarding future business. Gap analysis, while a helpful diagnostic tool, displays cash flows for only a single rate environment. EVE’s long-term horizon helps identify changes in optionality and longer-term positions. However, EVE’s liquidation perspective does not translate into the earnings-based measures that are the focus of managing and valuing a going concern. Net interest income simulations explicitly measure the exposure to earnings from changes in market rates of interest. In these simulations, our current financial position is combined with assumptions regarding future business to calculate net interest income under various hypothetical rate scenarios. The ALCO reviews earnings simulations over multiple years under various interest rate scenarios on a periodic basis. Reviewing these various measures provides us with a comprehensive view of our interest rate risk profile.

The following repricing gap analysis as of March 31, 2018 compares the difference between the amount of interest-earning assets and interest-bearing liabilities subject to repricing over a period of time. Management utilizes the repricing gap analysis as a diagnostic tool in managing net interest income and EVE risk measures.

Cumulative Gap to Assets	(1.6	)%	(0.3	)%	1.3 %	2.4 %

The twelve-month cumulative repricing gap to total assets was 2.4% and 3.0% as of March 31, 2018 and December 31, 2017 , respectively. The positive cumulative gap positions indicate that we have a greater amount of repricing earning assets than repricing interest-bearing liabilities over the subsequent twelve months. If interest rates increase then net interest income will increase and, conversely, if interest rates decrease then net interest income will decrease.

The allocation of non-maturity deposits and customer repurchase agreements to the one-month maturity category above is based on the estimated sensitivity of each product to changes in market rates. For example, if a product’s rate is estimated to increase by 50% as much as the market rates, then 50% of the account balance was placed in this category.

Utilizing net interest income simulations, the following net interest income metrics were calculated using rate shocks which move market rates in an immediate and parallel fashion. The variance percentages represent the change between the net interest income and EVE calculated under the particular rate scenario versus the net interest income and EVE that was calculated assuming market rates as of March 31, 2018 . Using a static balance sheet structure, the measures do not reflect all of management's potential counteractions.

Table of Contents

The following table presents an analysis of the potential sensitivity of our net interest income and EVE to changes in interest rates:

TABLE 19

	March 31, 2018		December 31, 2017		ALCO Limits
Net interest income change (12 months):
+ 300 basis points	3.3	%	3.0	%	n/a
+ 200 basis points	2.4	%	2.3	%	(5.0	)%
+ 100 basis points	1.4	%	1.3	%	(5.0	)%
- 100 basis points	(3.4	)%	(3.9	)%	(5.0	)%
Economic value of equity:
+ 300 basis points	(6.4	)%	(5.9	)%	(25.0	)%
+ 200 basis points	(4.0	)%	(3.7	)%	(15.0	)%
+ 100 basis points	(1.5	)%	(1.2	)%	(10.0	)%
- 100 basis points	(1.5	)%	(2.6	)%	(10.0	)%

We also model rate scenarios which move all rates gradually over twelve months (Rate Ramps) and model scenarios that gradually change the shape of the yield curve. Assuming a static balance sheet, a +300 basis point Rate Ramp increases net interest income (12 months) by 2.2% at March 31, 2018 and 2.0% at December 31, 2017 .

Our strategy is generally to manage to a neutral interest rate risk position. However, given the current interest rate environment, the interest rate risk position has been managed to a modestly asset-sensitive position. Currently, rising rates are expected to have a modest, positive effect on net interest income versus net interest income if rates remained unchanged.

The ALCO utilizes several tactics to manage our interest rate risk position. As mentioned earlier, the growth in transaction deposits provides funding that is less interest rate-sensitive than short-term time deposits and wholesale borrowings. On the lending side, we regularly sell long-term fixed-rate residential mortgages to the secondary market and have been successful in the origination of consumer and commercial loans with short-term repricing characteristics. Total variable and adjustable-rate loans were 57.1% and 56.6% of total loans as of March 31, 2018 and December 31, 2017 , respectively. As of March 31, 2018 , 78.8% of these loans, or 45.0% of total loans, are tied to the Prime and one-month LIBOR rates. The investment portfolio is used, in part, to manage our interest rate risk position. Finally, we have made use of interest rate swaps to commercial borrowers (commercial swaps) to manage our interest rate risk position as the commercial swaps effectively increase adjustable-rate loans. As of March 31, 2018 , the commercial swaps totaled $ 2.4 billion of notional principal, with $213.5 million in notional swap principal originated during the first three months of 2018 . The success of the aforementioned tactics has resulted in a moderately asset-sensitive position. For additional information regarding interest rate swaps, see Note 9 in this Report.

We desired to remain modestly asset-sensitive during the first three months of 2018 . A number of management actions and market occurrences resulted in an increase in the asset sensitivity of our interest rate risk position during the period. The increase was due to management's actions with the timing of funding loan and investment growth, as well as deposit activity. The primary driver increasing asset sensitivity was the strong interest rate swap activity. The swap activity occurred in conjunction with the growth in certain transaction accounts and time deposits referred to earlier.

We recognize that all asset/liability models have some inherent shortcomings. Asset/liability models require certain assumptions to be made, such as prepayment rates on interest-earning assets and repricing impact on non-maturity deposits, which may differ from actual experience. These business assumptions are based upon our experience, business plans, economic and market trends and available industry data. While management believes that its methodology for developing such assumptions is reasonable, there can be no assurance that modeled results will be achieved.

Furthermore, the metrics are based upon the balance sheet structure as of the valuation date and do not reflect the planned growth or management actions that could be taken.

RISK MANAGEMENT

As a financial institution, we take on a certain amount of risk in every business decision, transaction and activity. Our Board of Directors and senior management have identified seven major categories of risk: credit risk, market risk, liquidity risk, reputational risk, operational risk, legal and compliance risk and strategic risk. In its oversight role of our risk management function, the Board of Directors focuses on the strategies, analyses and conclusions of management relating to identifying, understanding and managing risks so as to optimize total stockholder value, while balancing prudent business and safety and soundness considerations.

The Board of Directors adopted a risk appetite statement that defines acceptable risk levels or risk limits under which the company seeks to operate in order to optimize returns, while managing risk. As such, the board monitors a host of risk metrics from both business and operational units, as well as by risk category, to provide insight into how the company’s performance aligns with our risk appetite. The risk appetite dashboard is reviewed periodically by the Board of Directors and senior management to ensure performance alignment with our risk appetite, and where appropriate, makes adjustments to applicable business strategies and tactics where risks approach our desired risk tolerance limits.

We support our risk management process through a governance structure involving our Board of Directors and senior management. The joint Risk Committee of our Board of Directors and the FNBPA Board of Directors helps ensure that business decisions are executed within appropriate risk tolerances. The Risk Committee has oversight responsibilities with respect to the following:

• identification, measurement, assessment and monitoring of enterprise-wide risk;

• development of appropriate and meaningful risk metrics to use in connection with the oversight of our businesses and strategies;

• review and assessment of our policies and practices to manage our credit, market, liquidity, legal, regulatory and operating risk (including technology, operational, compliance and fiduciary risks); and

• identification and implementation of risk management best practices.

The Risk Committee serves as the primary point of contact between our Board of Directors and the Risk Management Council, which is the senior management level committee responsible for risk management. Risk appetite is an integral element of our business and capital planning processes through our Board Risk Committee and Risk Management Council. We use our risk appetite processes to promote appropriate alignment of risk, capital and performance tactics, while also considering risk capacity and appetite constraints from both financial and non-financial risks. Our top-down risk appetite process serves as a limit for undue risk-taking for bottom-up planning from our various business functions. Our Board Risk Committee, in collaboration with our Risk Management Council, approves our risk appetite on an annual basis, or more frequently, as needed to reflect changes in the risk environment, with the goal of ensuring that our risk appetite remains consistent with our strategic plans and business operations, regulatory environment and our shareholders' expectations. Reports relating to our risk appetite and strategic plans, and our ongoing monitoring thereof, are regularly presented to our various management level risk oversight and planning committees and periodically reported up through our Board Risk Committee.

As noted above, we have a Risk Management Council comprised of senior management. The purpose of this committee is to provide regular oversight of specific areas of risk with respect to the level of risk and risk management structure. Management has also established an Operational Risk Committee that is responsible for identifying, evaluating and monitoring operational risks across FNB, evaluating and approving appropriate remediation efforts to address identified operational risks and providing periodic reports concerning operational risks to the Risk Management Council. The Risk Management Council reports on a regular basis to the Risk Committee of our Board of Directors regarding our enterprise-wide risk profile and other significant risk management issues. Our Chief Risk Officer is responsible for the design and implementation of our enterprise-wide risk management strategy and framework through the Compliance Department and the Information and Cyber Security Department, both of which report to the Chief Risk Officer, and ensures the coordinated and consistent implementation of risk management initiatives and strategies on a day-to-day basis. Our Compliance Department, which reports to the Chief Risk Officer, is responsible for developing policies and procedures and monitoring compliance with applicable laws and regulations. Our Information and Cyber Security Department is responsible for maintaining a risk assessment of our information and cyber security risks and ensuring appropriate controls are in place to manage and control such risks, including designing appropriate testing plans to ensure the integrity of information and cyber security controls. Further, our audit function performs an independent assessment of our internal controls environment and plays an integral role in testing the operation of the internal controls systems and reporting findings to management and our Audit Committee. Both the Risk Committee and Audit Committee of our Board of Directors regularly report on risk-related matters to the full Board of Directors. In addition, both the

Risk Committee of our Board of Directors and our Risk Management Council regularly assess our enterprise-wide risk profile and provide guidance on actions needed to address key and emerging risk issues.

The Board of Directors believes that our enterprise-wide risk management process is effective and enables the Board of Directors to:

• assess the quality of the information we receive;

• understand the businesses, investments and financial, accounting, legal, regulatory and strategic considerations and the risks that we face;

• oversee and assess how senior management evaluates risk; and

• assess appropriately the quality of our enterprise-wide risk management process.

RECONCILIATIONS OF NON-GAAP FINANCIAL MEASURES AND KEY PERFORMANCE INDICATORS TO GAAP

Reconciliations of non-GAAP operating measures and key performance indicators discussed in this Report to the most directly comparable GAAP financial measures are included in the following tables.

TABLE 20

Operating Net Income Available to Common Stockholders

(dollars in thousands)	Three Months Ended March 31, — 2018	2017
Net income available to common stockholders	$ 84,752	$ 20,969
Merger-related expense	—	52,724
Tax benefit of merger-related expense	—	(17,579	)
Merger-related net securities gains	—	(2,609	)
Tax expense of merger-related net securities gains	—	913
Operating net income available to common stockholders (non-GAAP)	$ 84,752	$ 54,418

The table above shows how operating net income available to common stockholders (non-GAAP) is derived from amounts reported in our financial statements. We believe this measurement helps investors understand the effect of acquisition activity and recent tax reform on reported results. We use operating net income available to common stockholders to better understand business performance and the underlying trends produced by core business activities. We believe merger-related expenses are not organic costs to run our operations and facilities. These charges represent expenses to satisfy contractual obligations of an acquired entity without any useful benefit to us and to convert and consolidate the entity’s records onto our platforms. These costs are specific to each individual transaction, and may vary significantly based on the size and complexity of the transaction.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The information called for by this item is provided in the Market Risk section of "Management’s Discussion and Analysis of Financial Condition and Results of Operations," which is included in Item 2 of this Report, and is incorporated herein by reference. There are no material changes in the information provided under Part II, Item 7A, “Quantitative and Qualitative Disclosures About Market Risk” included in our 2017 Annual Report on Form 10-K as filed with the SEC on February 28, 2018 .

ITEM 4. CONTROLS AND PROCEDURES

EVALUATION OF DISCLOSURE CONTROLS AND PROCEDURES. FNB’s management, with the participation of our principal executive and financial officers, evaluated our disclosure controls and procedures (as defined in Rules 13a–15(e) and 15d–15(e) under the Securities Exchange Act of 1934, as amended) as of the end of the period covered by this Quarterly Report on Form 10-Q. Based on this evaluation, our management, including the Chief Executive Officer (CEO) and the Chief Financial Officer (CFO), concluded that, as of the end of the period covered by this quarterly report, our disclosure controls and procedures were effective as of such date at the reasonable assurance level as discussed below to ensure that information required to be disclosed by us in the reports we file under the Securities Exchange Act of 1934, as amended, is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC and that such information is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure.

LIMITATIONS ON THE EFFECTIVENESS OF CONTROLS. FNB’s management, including the CEO and the CFO, does not expect that our disclosure controls and internal controls will prevent all errors and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within FNB have been detected. These inherent limitations include the realities that judgments in decision making can be faulty, and that breakdowns can occur because of simple error or mistake. In addition, controls can be circumvented by the individual acts of some persons, by collusion of two or more people or by management override of the controls.

CHANGES IN INTERNAL CONTROLS. The CEO and the CFO have evaluated the changes to our internal controls over financial reporting that occurred during our fiscal quarter ended March 31, 2018 , as required by paragraph (d) of Rules 13a–15 and 15d–15 under the Securities Exchange Act of 1934, as amended, and have concluded that there were no such changes that materially affected, or are reasonably likely to materially affect, our internal controls over financial reporting.
