NOTES TO THE UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

Note 1 Basis of Presentation

The accounting and reporting policies of First Commonwealth Financial Corporation and its subsidiaries (“First Commonwealth” or the “Company”) conform with generally accepted accounting principles in the United States of America (“GAAP”). The preparation of financial statements in conformity with GAAP requires management to make estimates, assumptions and judgments that affect the amounts reported in the financial statements and accompanying notes. Actual realized amounts could differ from those estimates. In the opinion of management, the unaudited interim condensed consolidated financial statements include all adjustments (consisting of only normal recurring adjustments) necessary for a fair presentation of First Commonwealth’s financial position, results of operations, comprehensive income, cash flows and changes in shareholders’ equity as of and for the periods presented.

The results of operations for the six months endedJune 30, 2015 are not necessarily indicative of the results that may be expected for the full year of 2015. These interim financial statements should be read in conjunction with First Commonwealth’s 2014 Annual Report on Form 10-K.

For purposes of reporting cash flows, cash and cash equivalents include cash on hand, amounts due from banks, federal funds sold and interest-bearing bank deposits. Generally, federal funds are sold for one-day periods.

Note 2 Supplemental Comprehensive Income Disclosures

The following table identifies the related tax effects allocated to each component of other comprehensive income (“OCI”) in the Condensed Consolidated Statements of Comprehensive Income. Reclassification adjustments related to securities available for sale are included in the "Net securities gains" line and reclassification adjustments related to losses on derivatives are included in the "Other operating expenses" line in the Condensed Consolidated Statements of Income.

Note 5 Commitments and Contingent Liabilities

Commitments and Letters of Credit

Standby letters of credit and commercial letters of credit are conditional commitments issued by First Commonwealth to guarantee the performance of a customer to a third party. The contract or notional amount of these instruments reflects the maximum amount of future payments that First Commonwealth could be required to pay under the guarantees if there were a

total default by the guaranteed parties, without consideration of possible recoveries under recourse provisions or from collateral held or pledged. In addition, many of these commitments are expected to expire without being drawn upon; therefore, the total commitment amounts do not necessarily represent future cash requirements.

The following table identifies the notional amount of those instruments at:

	June 30, 2015		December 31, 2014
	(dollars in thousands)
Financial instruments whose contract amounts represent credit risk:
Commitments to extend credit	$	1,610,767	$	1,635,948
Financial standby letters of credit	26,287		36,075
Performance standby letters of credit	25,878		25,915
Commercial letters of credit	2,146		2,611

The notional amounts outstanding as of June 30, 2015 include amounts issued in 2015 of $7.8 million in financial standby letters of credit and $1.8 million in performance standby letters of credit. There have been no commercial letters of credit issued during 2015. A liability of $0.2 million has been recorded as of June 30, 2015 and December 31, 2014, which represents the estimated fair value of letters of credit issued. The fair value of letters of credit is estimated based on the unrecognized portion of fees received at the time the commitment was issued.

Unused commitments and letters of credit provide exposure to future credit loss in the event of nonperformance by the borrower or guaranteed parties. Management’s evaluation of the credit risk related to these commitments resulted in the recording of a liability of $3.8 million as of June 30, 2015 and $3.1 million as of December 31, 2014. This liability is reflected in "Other liabilities" in the Condensed Consolidated Statements of Financial Condition. The credit risk evaluation incorporated probability of default, loss given default and estimated utilization for the next twelve months for each loan category and the letters of credit.

Legal Proceedings

There are no material legal proceedings to which First Commonwealth or its subsidiaries are a party, or of which their property is the subject, except proceedings which arise in the normal course of business and, in the opinion of management, will not have a material adverse effect on the consolidated operations, financial position, comprehensive income or cash flow of First Commonwealth or its subsidiaries.

Mortgage backed securities include mortgage backed obligations of U.S. Government agencies and obligations of U.S. Government-sponsored enterprises. These obligations have contractual maturities ranging from less than one year to approximately 30 years with lower anticipated lives to maturity due to prepayments. All mortgage backed securities contain a certain amount of risk related to the uncertainty of prepayments of the underlying mortgages. Interest rate changes have a direct impact upon prepayment speeds; therefore, First Commonwealth uses computer simulation models to test the average life and yield volatility of all mortgage backed securities under various interest rate scenarios to monitor the potential impact on earnings and interest rate risk positions.

Expected maturities will differ from contractual maturities because issuers may have the right to call or repay obligations with or without call or prepayment penalties. Other fixed income securities within the portfolio also contain prepayment risk.

Note 7 Impairment of Investment Securities

Securities Available for Sale and Held to Maturity

As required by FASB ASC Topic 320, “Investments – Debt and Equity Securities,” credit related other-than-temporary impairment on debt securities is recognized in earnings, while non-credit related other-than-temporary impairment on debt securities not expected to be sold is recognized in OCI. During the six months endedJune 30, 2015 and 2014, no other-than-temporary impairment charges were recognized.

First Commonwealth utilizes the specific identification method to determine the net gain or loss on debt securities and the average cost method to determine the net gain or loss on equity securities.

We review our investment portfolio on a quarterly basis for indications of impairment. This review includes analyzing the length of time and the extent to which the fair value has been lower than the cost, the financial condition and near-term prospects of the issuer, including any specific events which may influence the operations of the issuer and whether we are more likely than not to sell the security. We evaluate whether we are more likely than not to sell debt securities based upon our investment strategy for the particular type of security and our cash flow needs, liquidity position, capital adequacy, tax position and interest rate risk position. In addition, the risk of future other-than-temporary impairment may be influenced by additional bank failures, weakness in the U.S. economy, changes in real estate values and additional interest deferrals in our pooled trust preferred collateralized debt obligations. Our pooled trust preferred collateralized debt obligations are beneficial interests in securitized financial assets within the scope of FASB ASC Topic 325, “Investments – Other,” and are therefore evaluated for other-than-temporary impairment using management’s best estimate of future cash flows. If these estimated cash flows indicate that it is probable that an adverse change in cash flows has occurred, then other-than-temporary impairment would be recognized in accordance with FASB ASC Topic 320. There is a risk that First Commonwealth will record other-than-temporary impairment charges in the future. See Note 10, “Fair Values of Assets and Liabilities,” for additional information.

At June 30, 2015, fixed income securities issued by U.S. Government-sponsored enterprises comprised 57% of total unrealized losses due to changes in market interest rates. Pooled trust preferred collateralized debt obligations accounted for 41% of the unrealized losses primarily due to the illiquid market for this investment type. Obligations of U.S. Government agencies and obligations of state and political subdivisions account for the remaining 2% of total unrealized losses as a result of changes in market interest rates. At June 30, 2015, there are 70 debt securities in an unrealized loss position.

As of June 30, 2015, our corporate securities had an amortized cost and an estimated fair value of $1.9 million and $2.3 million, respectively. As of December 31, 2014, our corporate securities had an amortized cost and estimated fair value of $6.7 million and $7.3 million, respectively. Corporate securities are comprised of single issue trust preferred securities issued primarily by large regional banks. There were no corporate securities in an unrealized loss position as of June 30, 2015 and December 31, 2014. When unrealized losses exist on these investments, management reviews each of the issuer’s asset quality, earnings trends and capital position, to determine whether issues in an unrealized loss position were other-than-temporarily impaired. All interest payments on the corporate securities are being made as contractually required.

As of June 30, 2015, the book value of our pooled trust preferred collateralized debt obligations totaled $41.7 million with an estimated fair value of $35.5 million, which includes securities comprised of 275 banks and other financial institutions. All of our pooled securities are mezzanine tranches, three of which now have no senior class remaining in the issue. The credit rating on all of our issues are below investment grade. At the time of initial issue, the subordinated tranches ranged in size from approximately 7% to 35% of the total principal amount of the respective securities and no more than 5% of any pooled security

Lack of liquidity in the market for trust preferred collateralized debt obligations, below investment grade credit ratings and market uncertainties related to the financial industry are factors contributing to the impairment on these securities.

All of the Company's pooled trust preferred securities are included in the non-exclusive list issued by the regulatory agencies and therefore are not considered covered funds under the Volcker Rule.

On a quarterly basis we evaluate our debt securities for other-than-temporary impairment. During the six months endedJune 30, 2015 and 2014, there were no credit related other-than-temporary impairment charges recognized on our pooled trust preferred collateralized debt obligations. When evaluating these investments, we determine a credit-related portion and a non-credit related portion of other-than-temporary impairment. The credit related portion is recognized in earnings and represents the difference between book value and the present value of future cash flows. The non-credit related portion is recognized in OCI and represents the difference between the fair value of the security and the amount of credit-related impairment. A discounted cash flow analysis provides the best estimate of credit-related other-than-temporary impairment for these securities.

Additional information related to the discounted cash flow analysis follows:

Our pooled trust preferred collateralized debt obligations are measured for other-than-temporary impairment within the scope of FASB ASC Topic 325 by determining whether it is probable that an adverse change in estimated cash flows has occurred. Determining whether there has been an adverse change in estimated cash flows from the cash flows previously projected involves comparing the present value of remaining cash flows previously projected against the present value of the cash flows estimated at June 30, 2015. We consider the discounted cash flow analysis to be our primary evidence when determining whether credit related other-than-temporary impairment exists.

Results of a discounted cash flow test are significantly affected by other variables, such as the estimate of future cash flows, credit worthiness of the underlying banks and determination of probability of default of the underlying collateral. The following provides additional information for each of these variables:

• Estimate of Future Cash Flows – Cash flows are constructed in an INTEX cash flow model which includes each deal’s structural features. Projected cash flows include prepayment assumptions, which are dependent on the issuer's asset size and coupon rate. For collateral issued by financial institutions over $15 billion in asset size with a coupon over 7%, a 100% prepayment rate is assumed. Financial institutions over $15 billion with a coupon of 7% or under are assigned a prepayment rate of 40% for two years and 2% thereafter. Financial institutions with assets between $2 billion and $15 billion with coupons over 7% are assigned a 5% prepayment rate. For financial institutions below $2 billion, if the coupon is over 10%, a prepayment rate of 5% is assumed and for all other issuers, there is no prepayment assumption incorporated

ITEM 1. Financial Statements and Supplementary Data

NOTES TO THE UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Continued)

into the cash flows. The modeled cash flows are then used to estimate if all the scheduled principal and interest payments of our investments will be returned.

• Credit Analysis – A quarterly credit evaluation is performed for each of the 275 banks comprising the collateral across the various pooled trust preferred securities. Our credit evaluation considers all evidence available to us and includes the nature of the issuer’s business, its years of operating history, corporate structure, loan composition, loan concentrations, deposit mix, asset growth rates, geographic footprint and local economic environment. Our analysis focuses on profitability, return on assets, shareholders’ equity, net interest margin, credit quality ratios, operating efficiency, capital adequacy and liquidity.

• Probability of Default – A probability of default is determined for each bank and is used to calculate the expected impact of future deferrals and defaults on our expected cash flows. Each bank in the collateral pool is assigned a probability of default for each year until maturity. Currently, any bank that is in default is assigned a 100% probability of default and a 0% projected recovery rate. All other banks in the pool are assigned a probability of default based on their unique credit characteristics and market indicators with a 10% projected recovery rate. For the majority of banks currently in deferral we assume the bank continues to defer and will eventually default and, therefore, a 100% probability of default is assigned. However, for some deferring collateral there is the possibility that they become current on interest or principal payments at some point in the future and in those cases a probability that the deferral will ultimately cure is assigned. The probability of default is updated quarterly. As of June 30, 2015, default probabilities for performing collateral ranged from 0.33% to 75%.

Our credit evaluation provides a basis for determining deferral and default probabilities for each underlying piece of collateral. Using the results of the credit evaluation, the next step of the process is to look at pricing of senior debt or credit default swaps for the issuer (or where such information is unavailable, for companies having similar credit profiles as the issuer). The pricing of these market indicators provides the information necessary to determine appropriate default probabilities for each bank.

In addition to the above factors, our evaluation of impairment also includes a stress test analysis which provides an estimate of excess subordination for each tranche. We stress the cash flows of each pool by increasing current default assumptions to the level of defaults that results in an adverse change in estimated cash flows. This stressed breakpoint is then used to calculate excess subordination levels for each pooled trust preferred security. The results of the stress test allow management to identify those pools that are at a greater risk for a future break in cash flows so that we can monitor banks in those pools more closely for potential deterioration of credit quality.

Our cash flow analysis as of June 30, 2015, indicates that no credit-related other-than-temporary impairment has occurred on our pooled trust preferred securities during the six months endedJune 30, 2015. Based upon the analysis performed by management, it is probable that four of our pooled trust preferred securities will experience principal and interest shortfalls and therefore appropriate other-than-temporary charges were recorded in prior periods. These securities are identified in the table on page 16 with 0% “Excess Subordination as a Percentage of Current Performing Collateral.” For the remaining securities listed in that table, our analysis as of June 30, 2015 indicates it is probable that we will collect all contractual principal and interest payments. For four of those securities, PreTSL IX, PreTSL XIII, PreTSL XIV and MMCap I, other-than-temporary impairment charges were recorded in prior periods; however, due to improvement in the expected cash flows of these securities, it is now probable that all contractual payments will be received.

During 2008, 2009 and 2010, other-than-temporary impairment charges were recognized on all of our pooled trust preferred securities, except for PreTSL IV. Our cash flow analysis as of June 30, 2015, for all of these impaired securities indicates that it is now probable we will collect principal and interest in excess of what was estimated at the time other-than-temporary impairment charges were recorded. This change can be attributed to improvement in the underlying collateral for these securities and has resulted in the present value of estimated future principal and interest payments exceeding the securities' current book value. The excess for each bond of the present value of future cash flows over our current book value ranges from 21% to 141% and will be recognized as an adjustment to yield over the remaining life of these securities. The excess subordination recognized as an adjustment to yield is reflected in the following table as increases in cash flows expected to be collected.

(a) The beginning balance represents credit related losses included in other-than-temporary impairment charges recognized on debt securities in prior periods.

(b) Represents the increase in cash flows recognized in interest income during the period.

In the first six months of 2015 and 2014, no other-than-temporary impairment charges were recorded on equity securities. On a quarterly basis, management evaluates equity securities for other-than-temporary impairment by reviewing the severity and duration of decline in estimated fair value, research reports, analysts’ recommendations, credit rating changes, news stories, annual reports, regulatory filings, impact of interest rate changes and other relevant information. As of June 30, 2015 and 2014, there were no equity securities in an unrealized loss position.

Other Investments

As a member of the Federal Home Loan Bank ("FHLB"), First Commonwealth is required to purchase and hold stock in the FHLB to satisfy membership and borrowing requirements. The level of stock required to be held is dependent on the amount of First Commonwealth's mortgage-related assets and outstanding borrowings with the FHLB. This stock is restricted in that it can only be sold to the FHLB or to another member institution, and all sales of FHLB stock must be at par. As a result of these restrictions, FHLB stock is unlike other investment securities insofar as there is no trading market for FHLB stock and the transfer price is determined by FHLB membership rules and not by market participants. As of June 30, 2015 and December 31, 2014, our FHLB stock totaled $53.3 million and $44.5 million, respectively, and is included in “Other investments” on the Condensed Consolidated Statements of Financial Condition.

FHLB stock is held as a long-term investment and its value is determined based on the ultimate recoverability of the par value. First Commonwealth evaluates impairment quarterly and has concluded that the par value of its investment in FHLB stock will be recovered. Accordingly, no impairment charge was recorded on these securities during the six months ended June 30, 2015.

Credit Quality Information

As part of the on-going monitoring of credit quality within the loan portfolio, the following credit worthiness categories are used in grading our loans:

Pass Acceptable levels of risk exist in the relationship. Includes all loans not classified as OAEM, substandard or doubtful.

Other Assets Especially Mentioned (OAEM) Potential weaknesses that deserve management’s close attention. The potential weaknesses may result in deterioration of the repayment prospects or weaken the Company’s credit position at some future date. The credit risk may be relatively minor, yet constitute an undesirable risk in light of the circumstances surrounding the specific credit. No loss of principal or interest is expected.

Substandard Well-defined weakness or a weakness that jeopardizes the repayment of the debt. A loan may be classified as substandard as a result of deterioration of the borrower’s financial condition and repayment capacity. Loans for which repayment plans have not been met or collateral equity margins do not protect the Company may also be classified as substandard.

Doubtful Loans with the characteristics of substandard loans with the added characteristic that collection or liquidation in full, on the basis of presently existing facts and conditions, is highly improbable.

The use of creditworthiness categories to grade loans permits management’s use of migration analysis to estimate a portion of credit risk. The Company’s internal creditworthiness grading system provides a measurement of credit risk based primarily on an evaluation of the borrower’s cash flow and collateral. Movement between these rating categories provides a predictive measure of credit losses and therefore assists in determining the appropriate level for the loan loss reserves. Category ratings are reviewed each quarter, at which time management analyzes the results, as well as other external statistics and factors related to loan performance. Loans that migrate towards higher risk rating levels generally have an increased risk of default, whereas loans that migrate toward lower risk ratings generally will result in a lower risk factor being applied to those related loan balances.

Portfolio Risks

The credit quality of our loan portfolio can potentially represent significant risk to our earnings, capital, regulatory agency relationships, investment community reputation and shareholder returns. First Commonwealth devotes a substantial amount of resources managing this risk primarily through our credit administration department that develops and administers policies and procedures for underwriting, maintaining, monitoring and collecting activities. Credit administration is independent of lending departments and oversight is provided by the credit committee of the First Commonwealth Board of Directors.

Criticized loans have been evaluated when determining the appropriateness of the allowance for credit losses, which we believe is adequate to absorb losses inherent to the portfolio as of June 30, 2015. However, changes in economic conditions, interest rates, borrower financial condition, delinquency trends or previously established fair values of collateral factors could significantly change those judgmental estimates.

Age Analysis of Past Due Loans by Segment

The following tables delineate the aging analysis of the recorded investments in past due loans as of June 30, 2015 and December 31, 2014. Also included in these tables are loans that are 90 days or more past due and still accruing because they are well-secured and in the process of collection.

Nonaccrual Loans

The previous tables summarize nonaccrual loans by loan segment. The Company generally places loans on nonaccrual status when the full and timely collection of interest or principal becomes uncertain, when part of the principal balance has been charged off and no restructuring has occurred, or the loans reach a certain number of days past due. Generally, loans 90 days or more past due are placed on nonaccrual status, except for consumer loans, which are placed in nonaccrual status at 150 days past due.

When a loan is placed on nonaccrual, the accrued unpaid interest receivable is reversed against interest income and all future payments received are applied as a reduction to the loan principal. Generally, the loan is returned to accrual status when (a) all delinquent interest and principal becomes current under the terms of the loan agreement or (b) the loan is both well-secured and in the process of collection and collectability is no longer in doubt.

Impaired Loans

Management considers loans to be impaired when, based on current information and events, it is determined that the Company will not be able to collect all amounts due according to the loan contract, including scheduled interest payments. Determination of impairment is treated the same across all loan categories. When management identifies a loan as impaired, the impairment is measured based on the present value of expected future cash flows, discounted at the loan’s effective interest rate, except when the sole source for repayment of the loan is the operation or liquidation of collateral. When the loan is collateral dependent, the appraised value less estimated cost to sell is utilized. If management determines the value of the impaired loan is less than the recorded investment in the loan, impairment is recognized through an allowance estimate or a charge-off to the allowance. Troubled debt restructured loans on accrual status are also considered to be impaired loans.

When the ultimate collectability of the total principal of an impaired loan is in doubt and the loan is on nonaccrual status, all payments are applied to principal under the cost recovery method. When the ultimate collectability of the total principal of an impaired loan is not in doubt and the loan is on nonaccrual status, contractual interest is credited to interest income when received under the cash basis method.

There were $2.4 million of impaired loans held for sale at June 30, 2015. These loans were transferred to held for sale status in the first quarter of 2015 and were sold in July 2015, at which time a gain of $0.4 million was recognized. There were no impaired loans held for sale at December 31, 2014. During the six months endedJune 30, 2014, $3.1 million of impaired loans were sold, resulting in the recognition of a gain of $0.1 million. No gains were recognized on the sale of impaired loans during the six months endedJune 30, 2015.

Significant nonaccrual loans as of June 30, 2015, include the following:

• $7.4 million relationship of commercial and real estate loans to a local water facility construction company. These loans were originated from 2009 to 2013 and were placed in nonaccrual status during the fourth quarter of 2014. During the six months endedJune 30, 2015, charge-offs of $2.3 million related to this relationship were recorded. A valuation of the collateral was completed during the first quarter of 2015.

• $5.9 million relationship of commercial industrial loans to a local energy company. These loans were originated from 2008 to 2011 and were placed in nonaccrual status during the third quarter of 2013. Two of these loans were modified resulting

Note 10 Fair Values of Assets and Liabilities

FASB ASC Topic 820, “Fair Value Measurements and Disclosures”, requires disclosures for non-financial assets and non-financial liabilities, except for items that are recognized or disclosed at fair value in the financial statements on a recurring basis (at least annually). All non-financial assets are included either as a separate line item on the Condensed Consolidated Statements of Financial Condition or in the “Other assets” category of the Condensed Consolidated Statements of Financial Condition. Currently, First Commonwealth does not have any non-financial liabilities to disclose.

FASB ASC Topic 825, “Financial Instruments”, permits entities to irrevocably elect to measure select financial instruments and certain other items at fair value. The unrealized gains and losses are required to be included in earnings each reporting period for the items that fair value measurement is elected. First Commonwealth has elected not to measure any existing financial instruments at fair value under FASB ASC Topic 825; however, in the future we may elect to adopt this guidance for select financial instruments.

In accordance with FASB ASC Topic 820, First Commonwealth groups financial assets and financial liabilities measured at fair value in three levels based on the principal markets in which the assets and liabilities are transacted and the observability of the data points used to determine fair value. These levels are:

• Level 1 – Valuations for assets and liabilities traded in active exchange markets, such as the New York Stock Exchange (“NYSE”). Valuations are obtained from readily available pricing sources for market transactions involving identical assets or liabilities. Level 1 securities include equity holdings comprised of publicly traded bank stocks which were priced using quoted market prices.

• Level 2 – Valuations for assets and liabilities traded in less active dealer or broker markets. Valuations are obtained for identical or comparable assets or liabilities from alternative pricing sources with reasonable levels of price transparency. Level 2 includes Obligations of U.S. Government securities issued by Agencies and Sponsored Enterprises, Obligations of States and Political Subdivisions, corporate securities, FHLB stock, loans held for sale, interest rate derivatives (including interest rate caps, interest rate swaps and risk participation agreements), certain other real estate owned and certain impaired loans.

Level 2 investment securities are valued by a recognized third party pricing service using observable inputs. The model used by the pricing service varies by asset class and incorporates available market, trade and bid information as well as cash flow information when applicable. Because many fixed-income investment securities do not trade on a daily basis, the model uses available information such as benchmark yield curves, benchmarking of like investment securities, sector groupings and matrix pricing. The model will also use processes such as an option adjusted spread to assess the impact of interest rates and to develop prepayment estimates. Market inputs normally used in the pricing model include benchmark yields, reported trades, broker/dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers and reference data including market research publications.

Management validates the market values provided by the third party service by having another recognized pricing service price 100% of the securities on an annual basis and a random sample of securities each quarter, monthly monitoring of variances from prior period pricing and, on a monthly basis, evaluating pricing changes compared to expectations based on changes in the financial markets.

Other investments recorded in the Condensed Consolidated Statements of Financial Condition are comprised of FHLB stock whose estimated fair value is based on its par value. Additional information on FHLB stock is provided in Note 7, “Impairment of Investment Securities.”

Loans held for sale include residential mortgage loans originated for sale in the secondary mortgage market as well as an impaired commercial loan for which sale was considered an appropriate exit strategy. The estimated fair value for the mortgage loans were determined on the basis of rates obtained in the respective secondary market and the estimated fair value of the commercial loan was determined by market bids obtained from potential buyers.

Interest rate derivatives are reported at an estimated fair value utilizing Level 2 inputs and are included in other assets and other liabilities, and consist of interest rate swaps where there is no significant deterioration in the counterparties' (loan customers') credit risk since origination of the interest rate swap as well as interest rate caps and risk participation agreements. First Commonwealth values its interest rate swap and cap positions using a yield curve by taking market prices/rates for an appropriate set of instruments. The set of instruments currently used to determine the U.S. Dollar yield curve includes cash LIBOR rates from overnight to three months, Eurodollar futures contracts and swap rates from three years to thirty years. These

28

ITEM 1. Financial Statements and Supplementary Data

FIRST COMMONWEALTH FINANCIAL CORPORATION AND SUBSIDIARIES

NOTES TO THE UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Continued)

yield curves determine the valuations of interest rate swaps. Interest rate derivatives are further described in Note 11, “Derivatives.”

For purposes of potential valuation adjustments to our derivative positions, First Commonwealth evaluates the credit risk of its counterparties as well as our own credit risk. Accordingly, we have considered factors such as the likelihood of default, expected loss given default, net exposures and remaining contractual life, among other things, in determining if any fair value adjustments related to credit risk are required. We review our counterparty exposure quarterly, and when necessary, appropriate adjustments are made to reflect the exposure.

We also utilize this approach to estimate our own credit risk on derivative liability positions. In 2015, we have not realized any losses due to a counterparty's inability to pay any uncollateralized positions.

The estimated fair value for other real estate owned included in Level 2 is determined by either an independent market-based appraisal less estimated costs to sell or an executed sales agreement.

• Level 3 – Valuations for assets and liabilities that are derived from other valuation methodologies, including option pricing models, discounted cash flow models and similar techniques, and not based on market exchange, dealer or broker traded transactions. If the inputs used to provide the valuation are unobservable and/or there is very little, if any, market activity for the security or similar securities, the securities would be considered Level 3 securities. Level 3 valuations incorporate certain assumptions and projections in determining the fair value assigned to such assets or liabilities. The assets included in Level 3 are pooled trust preferred collateralized debt obligations, non-marketable equity investments, certain interest rate derivatives, certain other real estate owned and certain impaired loans.

Our pooled trust preferred collateralized debt obligations are collateralized by the trust preferred securities of individual banks, thrifts and bank holding companies in the United States. There has been little or no active trading in these securities since 2009; therefore, it is more appropriate to determine estimated fair value using a discounted cash flow analysis. Detail on our process for determining the appropriate cash flows for this analysis is provided in Note 7, “Impairment of Investment Securities.” The discount rate applied to the cash flows is determined by evaluating the current market yields for comparable corporate and structured credit products along with an evaluation of the risks associated with the cash flows of the comparable security. Due to the fact that there is no active market for the pooled trust preferred collateralized debt obligations, one key reference point is the market yield for the single issue trust preferred securities issued by banks and thrifts for which there is more activity than for the pooled securities. Adjustments are then made to reflect the credit and structural differences between these two security types.

Management validates the fair value of the pooled trust preferred collateralized debt obligations by monitoring the performance of the underlying collateral, discussing the discount rate, cash flow assumptions and general market trends with the specialized third party and confirming changes in the underlying collateral to the trustee reports. Management’s monitoring of the underlying collateral includes deferrals of interest payments, payment defaults, cures of previously deferred interest payments, any regulatory filings or actions and general news related to the underlying collateral. Management also evaluates fair value changes compared to expectations based on changes in the interest rates used in determining the discount rate and general financial markets.

The estimated fair value of the non-marketable equity investments included in Level 3 is based on par value.

For interest rate derivatives included in Level 3, the fair value incorporates credit risk by considering such factors as likelihood of default and expected loss given default based on the credit quality of the underlying counterparties (loan customers).

In accordance with ASU 2011-4, the following table provides information related to quantitative inputs and assumptions used in Level 3 fair value measurements.

	Fair Value (dollars in thousands)			Valuation Technique	Unobservable Inputs	Range / (weighted average)
Pooled Trust Preferred Securities	$	35,521		Discounted Cash Flow	Probability of default	0% - 100% (16.47%)

					NGL per barrel	$15.00 (c)
	520		(b)	Discounted Cash Flow	Discount Rate	1.90%
Other Real Estate Owned	18			Internal Valuation	N/A	N/A

(a) incorporates spread over risk free rate related primarily to credit quality and illiquidity of securities.

(b) the remainder of impaired loans valued using Level 3 inputs are not included in this disclosure as the values of those loans are based on bankruptcy agreement documentation.

(c) unobservable inputs are defined as follows: MCF - million cubic feet; BBL/d - barrels per day; NGL - natural gas liquid.

The significant unobservable inputs used in the fair value measurement of pooled trust preferred securities are the probability of default, discount rates and prepayment rates. Significant increases in the probability of default or discount rate used would result in a decrease in the estimated fair value of these securities, while decreases in these variables would result in higher fair value measurements. In general, a change in the assumption of probability of default is accompanied by a directionally similar change in the discount rate. In most cases, increases in the prepayment rate assumptions would result in a higher estimated fair value for these securities while decreases would provide for a lower value. The direction of this change is somewhat dependent on the structure of the investment and the amount of the investment tranches senior to our position.

The discount rate is the significant unobservable input used in the fair value measurement of impaired loans. Significant increases in this rate would result in a decrease in the estimated fair value of the loans, while a decrease in this rate would result in a higher fair value measurement. Other unobservable inputs in the fair value measurement of impaired loans relate to gas, oil and natural gas prices. Increases in these prices would result in an increase in the estimated fair value of the loans, while a decrease in these prices would result in a lower fair value measurement.

Total losses	$	(1,508	)	$	(3,748	)	$	(1,997	)	$	(3,817	)

Impaired loans over $100 thousand are individually reviewed to determine the amount of each loan considered to be at risk of non-collection. The fair value for impaired loans that are collateral based is determined by reviewing real property appraisals, equipment valuations, accounts receivable listings and other financial information. A discounted cash flow analysis is performed to determine fair value for impaired loans when an observable market price or a current appraisal is not available. For real estate secured loans, First Commonwealth’s loan policy requires updated appraisals be obtained at least every twelve months on all impaired loans with balances of $250 thousand and over. For real estate secured loans with balances under $250 thousand, we rely on broker price opinions. For non-real estate secured assets, the Company normally relies on third party valuations specific to the collateral type.

The fair value for other real estate owned determined by either an independent market-based appraisal less estimated costs to sell or an executed sales agreement is classified as Level 2. The fair value for other real estate owned determined using an internal valuation is classified as Level 3. Other real estate owned has a book cost of $6.5 million as of June 30, 2015 and consisted primarily of commercial real estate properties in Pennsylvania. We review whether events and circumstances subsequent to a transfer to other real estate owned have occurred that indicate the balance of those assets may not be recoverable. If events and circumstances indicate further impairment we will record a charge to the extent that the carrying value of the assets exceed their fair values, less estimated cost to sell, as determined by valuation techniques appropriate in the circumstances.

Certain other assets and liabilities, including goodwill and core deposit intangibles, are measured at fair value on a non-recurring basis; that is, the instruments are not measured at fair value on an ongoing basis but are subject to fair value adjustments only in certain circumstances. Additional information related to goodwill is provided in Note 12, “Goodwill.” There were no other assets or liabilities measured at fair value on a non-recurring basis during the six months endedJune 30, 2015.

FASB ASC 825-10, “Transition Related to FSP FAS 107-1” and APB 28-1, “Interim Disclosures about Fair Value of Financial Instruments,” requires disclosure of the fair value of financial assets and financial liabilities, including those financial assets and financial liabilities that are not measured and reported at fair value on a recurring basis or non-recurring basis.

Cash and due from banks and interest-bearing bank deposits: The carrying amounts for cash and due from banks and interest-bearing bank deposits approximate the estimated fair values of such assets.

Securities: Fair values for securities available for sale and held to maturity are based on quoted market prices, if available. If quoted market prices are not available, fair values are based on quoted market prices of comparable instruments. Pooled trust preferred collateralized debt obligations values are derived from other valuation methodologies, including option pricing models, discounted cash flow models and similar techniques, and not based on market exchange, dealer or broker traded transactions. These valuations incorporate certain assumptions and projections in determining the fair value assigned to each instrument. The carrying value of other investments, which includes FHLB stock, is considered a reasonable estimate of fair value.

Loans: The fair values of all loans are estimated by discounting the estimated future cash flows using interest rates currently offered for loans with similar terms to borrowers of similar credit quality adjusted for past due and nonperforming loans, which is not an exit price under FASB ASC Topic 820, “Fair Value Measurements and Disclosures.”

Loans Held for Sale: The estimated fair value of loans held for sale is based on market bids obtained from potential buyers.

Off-balance sheet instruments: Many of First Commonwealth’s off-balance sheet instruments, primarily loan commitments and standby letters of credit, are expected to expire without being drawn upon; therefore, the commitment amounts do not necessarily represent future cash requirements. FASB ASC Topic 460, “Guarantees” clarified that a guarantor is required to recognize, at the inception of a guarantee, a liability for the fair value of the obligation undertaken in issuing the guarantee. The carrying amount and fair value for standby letters of credit was $0.2 million at June 30, 2015 and December 31, 2014, respectively. See Note 5, “Commitments and Contingent Liabilities,” for additional information.

Deposit liabilities: The estimated fair value of demand deposits, savings accounts and money market deposits is the amount payable on demand at the reporting date because of the customers’ ability to withdraw funds immediately. The carrying value of variable rate time deposit accounts and certificates of deposit approximate their fair values at the report date. Also, fair values of fixed rate time deposits for both periods are estimated by discounting the future cash flows using interest rates currently being offered and a schedule of aggregated expected maturities.

Short-term borrowings: The fair values of borrowings from the FHLB were estimated based on the estimated incremental borrowing rate for similar types of borrowings. The carrying amounts of other short-term borrowings such as federal funds purchased and securities sold under agreement to repurchase were used to approximate fair value due to the short-term nature of the borrowings.

Long-term debt and subordinated debt: The fair value of long-term debt and subordinated debt is estimated by discounting the future cash flows using First Commonwealth’s estimate of the current market rate for similar types of borrowing arrangements or an announced redemption price.

Note 11 Derivatives

Derivatives Not Designated as Hedging Instruments

First Commonwealth is a party to interest rate derivatives that are not designated as hedging instruments. These derivatives relate to interest rate swaps that First Commonwealth enters into with customers to allow customers to convert variable rate loans to a fixed rate. First Commonwealth pays interest to the customer at a floating rate on the notional amount and receives interest from the customer at a fixed rate for the same notional amount. At the same time the interest rate swap is entered into with the customer, an offsetting interest rate swap is entered into with another financial institution. First Commonwealth pays the other financial institution interest at the same fixed rate on the same notional amount as the swap entered into with the customer, and receives interest from the financial institution for the same floating rate on the same notional amount.

FIRST COMMONWEALTH FINANCIAL CORPORATION AND SUBSIDIARIES

NOTES TO THE UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Continued)

The changes in the fair value of the swaps offset each other, except for the credit risk of the counterparties, which is determined by taking into consideration the risk rating, probability of default and loss given default for all counterparties.

We have fifteen risk participation agreements with financial institution counterparties for interest rate swaps related to loans in which we are a participant. The risk participation agreements provide credit protection to the financial institution should the borrower fail to perform on its interest rate derivative contract with the financial institution. We have three risk participation agreements with financial institution counterparties for interest rate swaps related to loans in which we are the lead bank. The risk participation agreement provides credit protection to us should the borrower fail to perform on its interest rate derivative contract with us.

First Commonwealth is also party to interest rate caps that are not designated as hedging instruments. These derivatives relate to contracts that First Commonwealth enters into with loan customers that provides a maximum interest rate on their variable rate loan. At the same time the interest rate cap is entered into with the customer, First Commonwealth enters into an offsetting interest rate cap with another financial institution. The notional amount and maximum interest rate on both interest cap contracts are identical.

The fee received, less the estimate of the loss for the credit exposure, was recognized in earnings at the time of the transaction.

Derivatives Designated as Hedging Instruments

The Company has entered into four interest rate swap contracts that were designated as cash flow hedges. The interest rate swaps have a total notional amount of $200.0 million, $85.0 million with an original maturity of three years and $115.0 million with and original maturity of four years. The Company's risk management objective for these hedges is to reduce its exposure to variability in expected future cash flows related to interest payments on commercial loans benchmarked to the 1-month LIBOR rate. Therefore, the interest rate swaps convert the interest payments on the first $200.0 million of 1-month LIBOR based commercial loans into fixed rate payments.

The periodic net settlement of interest rate swaps is recorded as an adjustment to Interest and fees on loans in the Condensed Consolidated Statements of Income. For the six months endedJune 30, 2015, there was a $0.9 million impact on interest income as a result of these interest rate swaps. Changes in the fair value of the effective portion of cash flow hedges are reported in OCI. When the cash flows associated with the hedged item are realized, the gain or loss included in OCI is recognized in "Interest and fees on loans," the same line item in the Condensed Consolidated Statements of Income as the income on the hedged items. The cash flow hedges were highly effective at June 30, 2015, and December 31, 2014, and changes in the fair value attributed to hedge ineffectiveness were not material.

The following table depicts the credit value adjustment recorded related to the notional amount of derivatives outstanding as well as the notional amount of risk participation agreements participated to other banks:

Note 12 Goodwill

FASB ASC Topic 350-20, “Intangibles – Goodwill and Other” requires an annual valuation of the fair value of a reporting unit that has goodwill and a comparison of the fair value to the book value of equity to determine whether the goodwill has been impaired. Goodwill is also required to be tested on an interim basis if an event or circumstance indicates that it is more likely than not that an impairment loss has been incurred. When triggering events or circumstances indicate that goodwill testing is required, an assessment of qualitative factors can be completed before performing the two step goodwill impairment test. ASU 2011-8 provides that if an assessment of qualitative factors determines it is more likely than not that the fair value of a reporting unit exceeds its carrying amount, then the two step goodwill impairment test is not required.

We consider First Commonwealth to be one reporting unit. The carrying amount of goodwill as of June 30, 2015 and December 31, 2014 was $161.4 million. No impairment charges on goodwill or other intangible assets were incurred in 2015 or 2014.

We test goodwill for impairment as of November 30th each year and again at any quarter-end if any material events occur during a quarter that may affect goodwill.

As of June 30, 2015, goodwill was not considered impaired; however, changing economic conditions that may adversely affect our performance, the fair value of our assets and liabilities, or our stock price could result in impairment, which could adversely affect earnings in future periods. Management will continue to monitor events that could impact this conclusion in the future.

Note 13 New Accounting Pronouncements

In January 2015, the FASB issued ASU No. 2015-01, "Income Statement - Extraordinary and Unusual Items (Subtopic 225-20)," which finalizes Proposed ASU No. 2014-220, and eliminates the concept of extraordinary items from U.S. GAAP. Accordingly, this ASU eliminates FASB ASC Subtopic 225-20, "Income Statement - Extraordinary and Unusual Items", which, until now, required that an entity separately classify, present, and disclose extraordinary events and transactions. This ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. The adoption of this ASU is not expected to have a material impact on First Commonwealth’s financial condition or results of operations.

This discussion and the related financial data are presented to assist in the understanding and evaluation of the consolidated financial condition and the results of operations of First Commonwealth Financial Corporation including its subsidiaries (“First Commonwealth”) for the six months endedJune 30, 2015 and 2014, and should be read in conjunction with the Condensed Consolidated Financial Statements and notes thereto included in this Form 10-Q.

Forward-Looking Statements

Certain statements contained in this report that are not historical facts may constitute “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and are intended to be covered by the safe harbor provisions of the Private Securities Litigation Reform Act of 1995, notwithstanding that such statements are not specifically identified as such. In addition, certain statements may be contained in our future filings with the Securities and Exchange Commission, in press releases, and in oral and written statements made by us or with our approval that are not statements of historical fact and constitute “forward-looking statements” as well. These statements, which are based on certain assumptions and describe our future plans, strategies and expectations, can generally be identified by the use of words such as “may,” “will,” “should,” “could,” “would,” “plan,” “believe,” “expect,” “anticipate,” “intend,” “estimate” or words of similar meaning. These forward-looking statements are subject to significant risks, assumptions and uncertainties, and could be affected by many factors, including, but not limited to: (1) local, regional, national and international economic conditions and the impact they may have on First Commonwealth and its customers; (2) volatility and disruption in national and international financial markets; (3) the effects of and changes in trade and monetary and fiscal policies and laws, including the interest rate policies of the Federal Reserve Board; (4) inflation, interest rate, commodity price, securities market and monetary fluctuations; (5) the effect of changes in laws and regulations (including laws and regulations concerning taxes, banking, securities and insurance) with which First Commonwealth or its customers must comply; (6) the soundness of other financial institutions; (7) political instability; (8) impairment of First Commonwealth’s goodwill or other intangible assets; (9) acts of God or of war or terrorism; (10) the timely development and acceptance of new products and services and perceived overall value of these products and services by users; (11) changes in consumer spending, borrowings and savings habits; (12) changes in the financial performance and/or condition of First Commonwealth’s borrowers; (13) technological changes; (14) acquisitions and integration of acquired businesses; (15) First Commonwealth’s ability to attract and retain qualified employees; (16) changes in the competitive environment in First Commonwealth’s markets and among banking organizations and other financial service providers; (17) the ability to increase market share and control expenses; (18) the effect of changes in accounting policies and practices, as may be adopted by the regulatory agencies, as well as the Public Company Accounting Oversight Board, the Financial Accounting Standards Board and other accounting standard setters; (19) the reliability of First Commonwealth’s vendors, internal control systems or information systems; (20) the costs and effects of legal and regulatory developments, the resolution of legal proceedings or regulatory or other governmental inquiries, the results of regulatory examinations or reviews and the ability to obtain required regulatory approvals; and (21) other risks and uncertainties described in this report and in the other reports that we file with the Securities and Exchange Commission, including our most recent Annual Report on Form 10-K.

In light of these risks, uncertainties and assumptions, you should not place undue reliance on any forward-looking statements in this report. We undertake no obligation to publicly update or otherwise revise any forward-looking statements, whether as a result of new information, future events or otherwise.

Explanation of Use of Non-GAAP Financial Measure

In addition to the results of operations presented in accordance with generally accepted accounting principles (“GAAP”), First Commonwealth management uses, and this quarterly report contains or references, certain non-GAAP financial measures, such as net interest income on a fully taxable equivalent basis. We believe this non-GAAP financial measure provides information useful to investors in understanding our underlying operational performance and our business and performance trends as it facilitates comparison with the performance of others in the financial services industry. Although we believe that this non-GAAP financial measure enhances investors’ understanding of our business and performance, this non-GAAP financial measure should not be considered an alternative to GAAP.

We believe the presentation of net interest income on a fully taxable equivalent basis ensures comparability of net interest income arising from both taxable and tax-exempt sources and is consistent with industry practice. Interest income per the Condensed Consolidated Statements of Income is reconciled to net interest income adjusted to a fully taxable equivalent basis on pages 41 and 47 for the six and three months endedJune 30, 2015 and 2014, respectively.

Results of Operations

Six Months EndedJune 30, 2015 Compared to Six Months EndedJune 30, 2014

Net Income

For the six months endedJune 30, 2015, First Commonwealth had net income of $27.7 million, or $0.31 diluted earnings per share, compared to net income of $24.2 million, or $0.26 diluted earnings per share, in the six months endedJune 30, 2014. The increase in net income was primarily the result of an increase in net interest income, reduction in the provision for credit losses and declines in noninterest expense, offset by declines in noninterest income.

For the six months endedJune 30, 2015, the Company’s return on average equity was 7.80% and its return on average assets was 0.88%, compared to 6.79% and 0.78%, respectively, for the six months endedJune 30, 2014.

Net Interest Income

Net interest income, on a fully taxable equivalent basis, was $95.2 million in the first six months of 2015, compared to $92.7 million for the same period in 2014. This increase was primarily due to growth in earning assets of $145.5 million, a 9 basis point, or $2.0 million, decrease in interest expense and a $1.0 million special dividend on FHLB stock received in 2015. Net interest income comprises a majority of our operating revenue (net interest income before provision expense plus noninterest income) at 75% and 74% for the six months endedJune 30, 2015 and 2014, respectively. The net interest margin, on a fully taxable equivalent basis, was 3.30% for both the six months endedJune 30, 2015 and June 30, 2014.

ITEM 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations (Continued)

FIRST COMMONWEALTH FINANCIAL CORPORATION AND SUBSIDIARIES

The taxable equivalent yield on interest-earning assets was 3.57% for the six months endedJune 30, 2015, a decrease of 7 basis points compared to the 3.64% yield for the same period in 2014. Growth in earning assets has helped to offset the spread compression, as average earning assets for the six months endedJune 30, 2015 increased $145.5 million, or 3%, compared to the same period in 2014. Average loans for the six months ended June 30, 2015 increased $185.4 million, or 4.3% compared to the same period in 2014. Investment portfolio purchases during the six months endedJune 30, 2015 have been primarily in mortgage-related assets with approximate durations of 48-60 months and municipal securities with a duration of five years. The mortgage-related investments have monthly principal payments that will provide for reinvestment opportunities as interest rates rise.

Reductions in the cost of interest-bearing liabilities offset the impact of lower yields on interest-earning assets. The cost of interest-bearing liabilities was 0.34% for the six months endedJune 30, 2015, compared to 0.43% for the same period in 2014. This decline is primarily due to a 29 basis point decrease in the cost of time deposits as maturities repriced to lower rates or were replaced with lower cost short-term borrowings.

For the six months endedJune 30, 2015, changes in interest rates negatively impacted net interest income by $2.8 million when compared with the same period in 2014. The lower yield on interest-earning assets adversely impacted net interest income by $2.9 million, while the decline in the cost of interest-bearing liabilities had a positive impact of $0.1 million. We have been able to partially mitigate the impact of lower interest rates and the effect on net interest income through improving the mix of deposits and borrowed funds, growing the loan portfolio and increasing our investment volumes within established interest rate risk management guidelines.

While decreases in interest rates and yields compressed the net interest margin, increases in average interest-earning assets offset the effect on net interest income. Changes in the volumes of interest-earning assets and interest-bearing liabilities positively impacted net interest income by $5.3 million in the six months endedJune 30, 2015, as compared to the same period in 2014. Higher levels of interest-earning assets resulted in an increase of $3.5 million in interest income, while volume changes decreased interest expense by $1.9 million, primarily as the result of changes in time deposits, including brokered deposits.

Net interest income also benefited from a $104.4 million increase in average net free funds at June 30, 2015 as compared to June 30, 2014. Average net free funds are the excess of noninterest-bearing demand deposits, other noninterest-bearing liabilities and shareholders’ equity over noninterest-earning assets. The largest component of the increase in net free funds was an increase of $91.4 million, or 9.8%, in noninterest-bearing demand deposit average balances. Additionally, higher cost time deposits continue to mature and reprice into lower cost deposits or other funding alternatives. Average time deposits for the six months endedJune 30, 2015 decreased by $380.2 million compared to the comparable period in 2014.

The following table reconciles interest income in the Condensed Consolidated Statements of Income to net interest income adjusted to a fully taxable equivalent basis for the six months endedJune 30:

Provision for Credit Losses

The provision for credit losses is determined based on management’s estimates of the appropriate level of the allowance for credit losses needed for probable losses inherent in the loan portfolio, after giving consideration to charge-offs and recoveries for the period. The provision for credit losses is an amount added to the allowance, against which credit losses are charged.

The table below provides a breakout of the provision for credit losses by loan category for the six months endedJune 30:

	2015					2014
	Dollars			Percentage		Dollars			Percentage
	(dollars in thousands)
Commercial, financial, agricultural and other	$	1,710		40	%	$	6,731		103	%
Real estate construction	(629		)	(15	)	(742		)	(11	)
Residential real estate	70			2		(190		)	(3	)
Commercial real estate	881			21		(75		)	(1	)
Loans to individuals	2,165			52		824			12
Total	$	4,197		100	%	$	6,548		100	%

The provision for credit losses for the six months endedJune 30, 2015decreased in comparison to the six months endedJune 30, 2014 by $2.4 million, or 36%, as a result of overall improvement in loan portfolio credit metrics. The majority of the 2015 provision expense is attributable to loans to individuals as a result of charge-offs in the indirect automobile portfolio. The provision expense for commercial, financial, agricultural loans is primarily related to an increase in historical loss factors for this category. Partially offsetting the change in historical loss factors was the release of $1.1 million in specific reserves related to $4.2 million in loans transfered to held for sale in the first quarter of 2015. Real estate construction reflects a negative provision expense due to a decline in historical loss factors for this category.

The majority of the 2014 provision expense is attributable to specific reserves for an $8.0 million commercial industrial relationship which was transferred to nonaccrual status during the first quarter 2014.

The allowance for credit losses was $45.3 million, or 1.01%, of total loans outstanding at June 30, 2015, compared to $52.1 million, or 1.17%, at December 31, 2014 and $50.7 million, or 1.17%, at June 30, 2014. The change compared to December 31, 2014, can be attributed to a $19.6 million, or 14%, decrease in criticized loans, which includes a reduction of $12.6 million, or 23%, in nonperforming loans as well as a $7.8 million decrease in the level of specific reserves held on impaired loans. Nonperforming loans as a percentage of total loans decreased to 1.00% at June 30, 2015 from 1.24% at December 31, 2014 and 1.07% as of June 30, 2014. The allowance to nonperforming loan ratio was 106.26%, 94.21% and 109.59% as of June 30, 2015, December 31, 2014 and June 30, 2014, respectively.

Noninterest income, excluding net securities gains and gain on sale of loans and other assets, increased$0.6 million, or 2%, for the first six months of 2015 compared to 2014. Insurance and retail brokerage commissions increased $1.4 million as a result of increased production and an agency acquisition in the fourth quarter of 2014. Offsetting that increase is a $0.7 million decrease in service charges on deposit accounts and a $0.1 milliondecrease in the other income category. The decrease in other income can be attributed to $0.3 million in revenue recognized in 2014 from our registered investment advisory business, which was sold in the first quarter of 2014.

Total noninterest income for the six months endedJune 30, 2015decreased$1.4 million in comparison to the six months endedJune 30, 2014. The most significant change includes a $3.1 milliondecrease in gain on sale of other assets as a result of a $1.2 million gain recognized in 2014 from the sale of the Company's registered investment advisory business and the sale of three OREO properties that resulted in gains of $2.4 million. Offsetting that decrease is a $1.0 million increase in the gain on sale of loans due to the Company reentering the secondary mortgage loan sector.

Noninterest expense, excluding loss on sale or write-down of assets, furniture and equipment expense related to IT conversion, conversion related expenses and operational losses (recoveries), increased$0.8 million, or 1%, for the six months endedJune 30, 2015 compared to the same period in 2014. Contributing to the 2015 increases are $1.0 million in salary and employee benefits expense as a result of normal merit increases as well as strategic initiatives such as the launch of the mortgage initiative and the acquisition of an insurance agency. Net occupancy increased $0.4 million due to higher property taxes and building repairs, and collection and repossession expense increased $0.3 million primarily due to costs related to one commercial relationship. Offsetting these increases is a $1.1 million decrease in furniture and equipment expense due to declines in equipment and software maintenance costs as a result of the IT system conversion which was completed in the third quarter of 2014.

Loss on sale or write-down of assets for the six months ended June 30, 2015 increased $0.7 million as compared to the same period in 2014. The loss in 2015 includes $1.1 million in write-downs on three OREO properties recognized as a result of updated appraisals as well as a $0.4 million write-down due to the anticipated sale of a bank building. The sale of this building and closing of the related branch office is estimated to provide $0.2 million in annual savings. The loss on sale or write-down of assets for the six months ended June 30, 2014 included a $0.7 million write-down on one OREO property.

Operational losses (recoveries) increased $1.8 million for the six months ended June 30, 2015. In the first six months of 2015, operational losses are largely due to fraud losses recognized in conjunction with several merchant debit card breaches. The negative expense recognized in the six months ended June 30, 2014 is a result of a $0.9 million insurance recovery related to a fraud loss recognized in 2012.

During the third quarter of 2014, First Commonwealth completed a system conversion to the Jack Henry and Associates SilverLake System core processing software and outsourced certain data processing services that had previously been performed in-house. Expenses related to the conversion included accelerated depreciation for data processing hardware and software, early termination charges on previous contracts, and staffing and employment-related charges. During the six months endedJune 30, 2014, $4.2 million in accelerated depreciation and $0.9 million in other conversion related expenses were recognized.

Income Tax

The provision for income taxes increased$1.9 million for the six months endedJune 30, 2015, compared to the corresponding period in 2014. The higher provision for income taxes was the result of a $5.3 millionincrease in the level of income before taxes.

We applied the “annual effective tax rate approach” to determine the provision for income taxes, which applies an annual forecast of tax expense as a percentage of expected full year income, for the six months endedJune 30, 2015 and 2014.

We generate an annual effective tax rate that is less than the statutory rate of 35% due to benefits resulting from tax-exempt interest, income from bank-owned life insurance and tax benefits associated with low income housing tax credits, which are relatively consistent regardless of the level of pretax income. The level of tax benefits that reduced our tax rate below the 35% statutory rate produced an annual effective tax rate of 29.8% and 28.9% for the six months endedJune 30, 2015 and 2014, respectively.

As of June 30, 2015, our deferred tax assets totaled $40.2 million. Based on our evaluation as of June 30, 2015, we determined that it is more likely than not that all of these assets will be realized. As a result, a valuation allowance against these assets was not needed. In evaluating the need for a valuation allowance, we estimate future taxable income based on management approved forecasts, evaluation of historical earning levels and consideration of potential tax strategies. If future events differ from our current forecasts, we may need to establish a valuation allowance, which could have a material impact on our financial condition and results of operations.

Three Months EndedJune 30, 2015 Compared to Three Months EndedJune 30, 2014

Net Income

For the three months endedJune 30, 2015, First Commonwealth had net income of $13.4 million, or $0.15 per share, compared to net income of $11.9 million, or $0.13 per share, in the three months endedJune 30, 2014. For the three months endedJune 30, 2015, the Company’s return on average equity was 7.57% and its return on average assets was 0.85%, compared to 6.62% and 0.77%, respectively, for the three months endedJune 30, 2014. The increase in net income was primarily the result of a reduction in the provision for credit losses, an increase in net interest income and declines in noninterest expense, offset by declines in noninterest income.

Net Interest Income

Net interest income, on a fully taxable equivalent basis, was $47.2 million in the second quarter of 2015, compared to $46.2 million for the same period in 2014. This increase was primarily due a growth in interest-earning assets and a decline in the cost of interest-bearing liabilities. The net interest margin, on a fully taxable equivalent basis, was 3.26% for both the three months endedJune 30, 2015 and June 30, 2014.

The taxable equivalent yield on interest-earning assets was 3.52% for the three months endedJune 30, 2015, a decrease of 8 basis points compared to the 3.60% yield for the same period in 2014. Growth in earning assets has helped to offset the spread compression, as average interest-earning assets for the three months endedJune 30, 2015 increased $131.6 million, or 2%, compared to the comparable period in 2014. Average loans increased $199.7 million, or 4.6%, comparing the three months ended June 30, 2015 to the same period in 2014. Investment portfolio purchases during the three months endedJune 30, 2015 have been primarily in mortgage-related assets with approximate durations of 48-60 months and municipal securities with a

duration of five years. The mortgage-related investments have monthly principal payments that will provide for reinvestment opportunities as interest rates rise.

Reductions in the cost of interest-bearing liabilities offset the impact of lower yields on interest-earning assets. The cost of interest-bearing liabilities was 0.33% for the three months endedJune 30, 2015, compared to 0.43% for the same period in 2014. This decline can be attributed to a 32 basis point decrease in the cost of time deposits, as maturities were repriced lower or replaced with lower cost short-term borrowings.

For the three months endedJune 30, 2015, changes in interest rates negatively impacted net interest income by $1.7 million when compared with the same period in 2014. The lower yield on interest-earning assets adversely impacted net interest income by $1.7 million, while the decline in the cost of interest-bearing liabilities had a positive impact of $25 thousand.

While decreases in interest rates and yields compressed the net interest margin, increases in average interest-earning assets offset the effect on net interest income. Changes in the volumes of interest-earning assets and interest-bearing liabilities positively impacted net interest income by $2.7 million in the three months endedJune 30, 2015, as compared to the same period in 2014. Higher levels of interest-earning assets resulted in an increase of $1.7 million in interest income, while volume changes decreased interest expense by $1.0 million, primarily as the result of changes in short-term borrowings and time deposits, including brokered deposits.

Net interest income also benefited from a $71.4 million increase in average net free funds at June 30, 2015 as compared to June 30, 2014. Average net free funds are the excess of noninterest-bearing demand deposits, other noninterest-bearing liabilities and shareholders’ equity over noninterest-earning assets. The largest component of the increase in net free funds was an increase of $76.7 million, or 7.9%, in noninterest-bearing demand deposit average balances. Additionally, higher cost time deposits continue to mature and reprice into lower cost deposits or other funding alternatives. Average time deposits for the three months endedJune 30, 2015 decreased by $419.1 million compared to the comparable period in 2014.

Provision for Credit Losses

The provision for credit losses is determined based on management’s estimates of the appropriate level of the allowance for credit losses needed for probable losses inherent in the loan portfolio, after giving consideration to charge-offs and recoveries for the period. The provision for credit losses is an amount added to the allowance, against which credit losses are charged.

The table below provides a breakout of the provision for credit losses by loan category for the three months endedJune 30:

	2015					2014
	Dollars			Percentage		Dollars			Percentage
	(dollars in thousands)
Commercial, financial, agricultural and other	$	2,051		67	%	$	1,753		53	%
Real estate construction	(94		)	(3	)	(187		)	(6	)

Loans to individuals	993			33		627			19
Total	$	3,038		100	%	$	3,317		100	%

The provision for credit losses for the three months ended June 30, 2015decreased slightly in comparison to the three months endedJune 30, 2014 by $0.3 million, or 8%. The majority of the 2015 provision expense is attributable to loans to commercial, financial, agricultural and other loans primarily due to increases in historical loss factors, as well as loans to individuals as a result of charge-offs in the indirect automobile portfolio. The residential real estate and real estate construction categories reflect negative provision expense due to declines in the historical loss factor for these categories.

The majority of the 2014 provision expense is attributable to specific reserves for two commercial relationships, which were partially offset by the release of approximately $2.7 million in reserves related to another relationship.

Noninterest income, excluding net securities gains and gain on sale of loans and other assets, increased$0.5 million, or 3%, for the second quarter of 2015 compared to 2014. Insurance and retail brokerage commissions increased $0.6 million as a result of increased production and an agency acquisition in the fourth quarter of 2014. Offsetting that increase is a $0.3 million decrease in service charges on deposit accounts.

Total noninterest income for the three months endedJune 30, 2015decreased$0.7 million in comparison to the three months endedJune 30, 2014. The most significant change includes a $1.7 milliondecrease in gain on sale of assets due to the sale of an

OREO property in the second quarter of 2014 which resulted in a gain of $2.0 million. This decrease was offset by a $0.6 million increase in gains on the sale of loans due to the Company reentering the secondary mortgage market.

Noninterest expense, excluding loss on sale or write-down of assets, furniture and equipment expense related to IT conversion, conversion related expenses and operational losses (recoveries), decreased$0.1 million for the three months endedJune 30, 2015 compared to the same period in 2014. Contributing to the 2015 decrease is $0.5 million in furniture and equipment expense due to lower maintenance costs resulting from the IT system conversion completed in the third quarter of 2014. Other expenses decreased $0.4 million largely due to declines in expense related to data lines and telephones. Offsetting these decreases is a $0.5 million increase in collection and repossession expense as well as a $0.3 million increase in other professional fees and services.

Loss on sale or write-down of assets for the three months ended June 30, 2015 includes $1.1 million in write-downs on three OREO properties recognized as a result of updated appraisals as well as a $0.4 million write-down due to the anticipated sale of a bank building. The loss on sale or write-down of assets for the three months ended June 30, 2014 included a $0.7 million write-down on one OREO property.

During the third quarter of 2014, First Commonwealth completed a system conversion to the Jack Henry and Associates SilverLake System core processing software and outsourced certain data processing services that had previously been performed in-house. Expenses related to the conversion included accelerated depreciation for data processing hardware and software, early termination charges on previous contracts, and staffing and employment-related charges. During the three months endedJune 30, 2014, $2.1 million in accelerated depreciation and $0.5 million in other conversion related expenses were recognized.

Income Tax

The provision for income taxes increased$0.9 million for the three months endedJune 30, 2015, compared to the corresponding period in 2014. The higher provision for income taxes was the result of a $2.4 millionincrease in the level of income before taxes.

We applied the “annual effective tax rate approach” to determine the provision for income taxes, which applies an annual forecast of tax expense as a percentage of expected full year income, for the three months endedJune 30, 2015 and 2014.

We generate an annual effective tax rate that is less than the statutory rate of 35% due to benefits resulting from tax-exempt interest, income from bank-owned life insurance and tax benefits associated with low income housing tax credits, which are

51

FIRST COMMONWEALTH FINANCIAL CORPORATION AND SUBSIDIARIES

relatively consistent regardless of the level of pretax income. The level of tax benefits that reduced our tax rate below the 35% statutory rate produced an annual effective tax rate of 29.4% and 28.5% for the three months endedJune 30, 2015 and 2014, respectively.

Liquidity

Liquidity refers to our ability to meet the cash flow requirements of depositors and borrowers as well as our operating cash needs with cost-effective funding. We generate funds to meet these needs primarily through the core deposit base of First Commonwealth Bank and the maturity or repayment of loans and other interest-earning assets, including investments. During the first six months of 2015, liquidity provided from the net increase in short-term borrowings totaled $126.0 million, while the maturity and redemption of investment securities provided $237.2 million. This liquidity provided funds needed to originate loans, purchase investment securities and fund depositor withdrawals.  We also have available unused wholesale sources of liquidity, including overnight federal funds and repurchase agreements, advances from the FHLB of Pittsburgh, borrowings through the discount window at the Federal Reserve Bank of Cleveland (“FRB”) and access to certificates of deposit through brokers.

In order to increase and diversify our funding sources, we participate in the Certificate of Deposit Account Registry Services (“CDARS”) program as part of an Asset/Liability Committee (“ALCO”) strategy to increase and diversify funding sources. As of June 30, 2015, our maximum borrowing capacity under this program was $945.4 million and as of that date there was $15.0 million outstanding. Also included in this amount is a reciprocal program which allows our depositors to receive expanded FDIC coverage by placing multiple certificates of deposit at other CDARS member banks. As of June 30, 2015, our outstanding certificates of deposits from this program have an average weighted rate of 0.19% and an average original term of 55 days.

An additional source of liquidity is the FRB Borrower-in-Custody of Collateral program, which enables us to pledge certain loans that are not being used as collateral at the FHLB as collateral for borrowings at the FRB. At June 30, 2015, the borrowing capacity under this program totaled $683.8 million and there were no amounts outstanding.

As of June 30, 2015, our maximum borrowing capacity at the FHLB of Pittsburgh was $1.6 billion and as of that date amounts used against this capacity included $1.1 billion in outstanding borrowings and $28.2 million in letter of credit commitments used for pledging public funds and other non-deposit purposes.

We also have available unused federal funds lines with four correspondent banks. These lines have an aggregate commitment of $170.0 million with $24.0 million outstanding as of June 30, 2015.

First Commonwealth Financial Corporation has an unsecured $15.0 million line of credit with another financial institution. As of June 30, 2015, there are no amounts outstanding on this line.

First Commonwealth’s long-term liquidity source is its core deposit base. Core deposits are the most stable source of liquidity a bank can have due to the long-term relationship with a deposit customer. The level of deposits during any period is influenced by factors outside of management’s control, such as the level of short-term and long-term market interest rates and yields offered on competing investments, such as money market mutual funds. The following table shows a breakdown of the components of First Commonwealth’s deposits:

	June 30, 2015		December 31, 2014
	(dollars in thousands)
Noninterest-bearing demand deposits	$	1,068,230	$	989,027
Interest-bearing demand deposits	76,865		81,851
Savings deposits	2,441,888		2,402,288
Time deposits	623,124		842,345
Total	$	4,210,107	$	4,315,511

During the first six months of 2015, total deposits decreased$105.4 million due to a $219.2 milliondecrease in time deposits partially offset by increases of $34.6 million in interest-bearing demand and savings deposits and $79.2 million in noninterest-bearing deposits. The decrease in time deposits is due to a decline in wholesale certificates of deposit of $135.0 million coupled with a decline in core certificates of deposit of $84.3 million. Wholesale certificates can, at times, offer a more attractive source of incremental funding as they can, depending on market conditions, have a lower incremental cost of funds than traditional certificates of deposit funding.

Market Risk

The following gap analysis compares the difference between the amount of interest-earning assets and interest-bearing liabilities subject to repricing over a period of time. The ratio of rate-sensitive assets to rate-sensitive liabilities repricing within a one-year period was 0.72 and 0.69 at June 30, 2015 and December 31, 2014, respectively. A ratio of less than one indicates a higher level of repricing liabilities over repricing assets over the next twelve months. The level of First Commonwealth's ratio is largely driven by the modeling of interest-bearing non-maturity deposits, which are included in the analysis as repricing within one year.

Gap analysis has limitations due to the static nature of the model that holds volumes and consumer behaviors constant in all economic and interest rate scenarios. A lower level of rate sensitive assets to rate sensitive liabilities repricing in one year could indicate reduced net interest income in a rising interest rate scenario, and conversely, increased net interest income in a declining interest rate scenario. However, the gap analysis incorporates only the level of interest-earning assets and interest-bearing liabilities and not the sensitivity each has to changes in interest rates. The impact of the sensitivity to changes in interest rates is provided in the table below the gap analysis.

The following is the gap analysis as of June 30, 2015 and December 31, 2014:

The following table represents the potential sensitivity of our annual net interest income to immediate changes in interest rates versus if rates remained unchanged utilizing a flat balance sheet.

	Net interest income change (12 months)
	-200			-100			+100			+200
	(dollars in thousands)
June 30, 2015 ($)	$	(12,398	)	$	(6,411	)	$	(466	)	$	(340	)

December 31, 2014 (%)	(6.4		)%	(3.5		)%	0.3		%	0.8		%

The analysis and model used to quantify the sensitivity of our net interest income becomes less reliable in a decreasing 200 basis point scenario given the current low interest rate environment. Results of the 100 and 200 basis point interest rate decline scenario are affected by the fact that many of our interest-bearing liabilities are at rates below 1%, and therefore cannot decline 100 or 200 basis points, yet our interest-sensitive assets are able to decline by these amounts. In the six months endedJune 30, 2015 and 2014, the cost of our interest-bearing liabilities averaged 0.34% and 0.43%, respectively, and the yield on our average interest-earning assets, on a fully taxable equivalent basis, averaged 3.57% and 3.64%, respectively.

During the second quarter of 2014, the Company analyzed the assumptions used when estimating the volatility of our non-maturity deposits. As a result of this analysis, the duration of our nonmaturity deposits was determined to be 1.4 years longer

54

ITEM 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations (Continued)

FIRST COMMONWEALTH FINANCIAL CORPORATION AND SUBSIDIARIES

than previously modeled and the repricing sensitivity was determined to be 26 basis points less in a 100 basis point increase in interest rates.

During the first quarter of 2015, the Company entered into cash flow interest rate swaps in which we extended the duration of $100.0 million of the $1.3 billion LIBOR based loans in our loan portfolio into fixed interest rates for a period of three or four years. These swaps add two basis points of protection to the net interest margin as a hedge against a prolonged low-rate environment. A similar cash flow interest rate swap, with a notional amount of $100.0 million, was entered into in 2014. Please refer to Note 11, "Derivatives," for additional information on interest rate swaps.

Asset/liability models require that certain assumptions be made, such as prepayment rates on earning assets and the impact of pricing on non-maturity deposits, which may differ from actual experience. These business assumptions are based upon our experience, business plans and published industry experience. While management believes such assumptions to be reasonable, there can be no assurance that modeled results will approximate actual results.

Credit Risk

First Commonwealth maintains an allowance for credit losses at a level deemed sufficient for losses inherent in the loan portfolio at the date of each statement of financial condition. Management reviews the adequacy of the allowance on a quarterly basis to ensure that the provision for credit losses has been charged against earnings in an amount necessary to maintain the allowance at a level that is appropriate based on management’s assessment of probable estimated losses.

First Commonwealth’s methodology for assessing the appropriateness of the allowance for credit losses consists of several key elements. These elements include an assessment of individual impaired loans with a balance greater than $0.1 million, loss experience trends and other relevant factors.

First Commonwealth also maintains a reserve for unfunded loan commitments and letters of credit based upon credit risk and probability of funding. The reserve totaled $3.8 million at June 30, 2015 and is classified in "Other liabilities" on the Condensed Consolidated Statements of Financial Condition.

First Commonwealth defines exposure to the Oil and Gas Industry as any borrower who is involved in exploration and production, and any company in the industry supply chain that generates 40% or more of their sales revenue from exploration and production companies.

As of June 30, 2015, the Company had a total of $139.7 million in commitments to the Oil and Gas Industry, with $59.4 million in outstanding loan balances against those commitments. Of this total, commitments of $42.2 million with outstanding balances of $14.5 million are for exploration and production, while $97.5 million in commitments, with outstanding balances of $44.9 million, are related to ancillary businesses.

Two customers account for 82.9% of the loans related to exploration and production and both are pass rated credits. These credit facilities are primarily used to support letters of credit and have little or no usage. Two commercial relationships in this category, totaling $3.8 million, are on non-performing status and have been even before the oil price decline in the third quarter of 2014.

The ancillary businesses sector consist of well services, transportation, and providing equipment and materials to support the oil and gas industry. Two customers, which account for 41.0% of the ancillary business exposure, are bulk transporters of refined product and are not expected to be negatively impacted from lower oil prices. There are four pass rated credits, with total commitments of $42.5 million, in the ancillary business sector that will see some impact from reduced drilling activity due to lower oil and gas prices. The Company will continue to monitor their performance accordingly. One commercial relationship with $2.3 million in outstanding loans for an ancillary business has been on non-performing status since 2012.

Nonperforming loans include nonaccrual loans and loans classified as troubled debt restructurings. Nonaccrual loans represent loans on which interest accruals have been discontinued. Troubled debt restructured loans are those loans whose terms have been renegotiated to provide a reduction or deferral of principal or interest as a result of the deteriorating financial position of the borrower, who could not obtain comparable terms from alternative financing sources. In the first six months of 2015, twenty-six loans totaling $3.2 million were identified as troubled debt restructurings.

The balance of troubled debt restructured loans, including held for sale loans, decreased$6.2 million due primarily to a charge-off of $3.3 million related to a loan relationship with a local energy company, the payoff of a $1.4 million commercial industrial loan with a local lumber company and a $1.2 million charge-off on a loan transferred to held for sale. Please refer to Note 8, “Loans and Allowance for Credit Losses,” for additional information on troubled debt restructurings.

FIRST COMMONWEALTH FINANCIAL CORPORATION AND SUBSIDIARIES

We discontinue interest accruals on a loan when, based on current information and events, it is probable that we will be unable to fully collect principal or interest due according to the contractual terms of the loan. A loan is also placed on nonaccrual status when, based on regulatory definitions, the loan is maintained on a “cash basis” due to the weakened financial condition of the borrower. Generally, loans 90 days or more past due are placed on nonaccrual status, except for consumer loans which are placed on nonaccrual status at 150 days past due.

Nonperforming loans are closely monitored on an ongoing basis as part of our loan review and work-out process. The probable risk of loss on these loans is evaluated by comparing the loan balance to the fair value of any underlying collateral or the present value of projected future cash flows. Losses or a specifically assigned allowance for loan losses are recognized where appropriate.

Nonperforming loans, including loans held for sale, decreased$10.1 million to $45.1 million at June 30, 2015 compared to $55.3 million at December 31, 2014. This decrease is primarily due to a $3.3 million charge-off related to a commercial industrial loan relationship with a local energy company, a $2.3 million charge-off related to a commercial industrial loan relationship with a local water facility construction company and a $1.4 million payoff related to a commercial relationship with a local lumber company.

The allowance for credit losses as a percentage of nonperforming loans was 106.26% as of June 30, 2015 compared to 94.21% at December 31, 2014 and 109.59% at June 30, 2014. The amount of specific reserves included in the allowance for nonperforming loans was determined by using fair values obtained from current appraisals and updated discounted cash flow analyses. The allowance for credit losses includes specific reserves of $1.7 million and general reserves of $43.7 million as of June 30, 2015. Specific reserves decreased$7.8 million from December 31, 2014, and $4.4 million from June 30, 2014. The decrease in specific reserves in the first six months of 2015 is primarily due to charge-offs of loans which were provided for in prior periods. Management believes that the allowance for credit losses is at a level deemed sufficient to absorb losses inherent in the loan portfolio at June 30, 2015.

Criticized loans totaled $120.5 million at June 30, 2015 and represented 2.7% of the loan portfolio. The level of criticized loans decreased as of June 30, 2015 when compared to December 31, 2014, by $19.6 million, or 14.0%. Classified loans totaled $79.9 million at June 30, 2015 compared to $67.8 million at December 31, 2014, an increase of $12.2 million, or 18.0%. Delinquency on accruing loans for the same period decreased$8.6 million, or 45.7%, the majority of which are commercial real estate and residential real estate loans.

The allowance for credit losses was $45.3 million at June 30, 2015 or 1.01% of total loans outstanding compared to 1.17% reported at December 31, 2014 and 1.17% at June 30, 2014. General reserves, or the portion of the allowance related to loans which were not specifically evaluated for impairment, as a percentage of non-impaired loans were 0.98% at June 30, 2015 compared to 0.97% at December 31, 2014 and 1.04% at June 30, 2014.

During the six months endedJune 30, 2015, loans increased$33.5 million, or less than 1%, compared to balances outstanding at December 31, 2014. All categories of loans reflected growth during the first six months of 2015, except for residental real estate loans and loans to individuals. Declines in the loans to individuals category is primarily due to runoff in home equity installment loans. The decline in residential real estate loans is the result of continued runoff in our mortgage portfolio, as many of the loans originated by our mortgage banking area are sold in the secondary market.

Net charge-offs for the six months endedJune 30, 2015 totaled $10.9 million compared to $10.0 million for the six months endedJune 30, 2014. The most significant charge-offs during the six months endedJune 30, 2015 include a $2.3 million partial

charge-off of two commercial industrial loans related to a local energy company and a $1.2 million charge-off of a commercial relationship that was transferred to loans held for sale.

Capital Resources

At June 30, 2015, shareholders’ equity was $711.2 million, a decrease of $4.9 million from December 31, 2014. The decrease was primarily the result of $25.4 million of common stock repurchases and $12.6 million of dividends paid to shareholders, offset by $27.7 million in net income and increases of $4.4 million in the fair value of available for sale investments. Cash dividends declared per common share were $0.14 for the six months endedJune 30, 2015 and 2014.

First Commonwealth and First Commonwealth Bank are subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on First Commonwealth’s financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, First Commonwealth and First Commonwealth Bank must meet specific capital guidelines that involve quantitative measures of First Commonwealth’s assets, liabilities and certain off-balance sheet items as calculated under regulatory accounting practices. First Commonwealth’s capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weighting and other factors.

First Commonwealth maintains capital to absorb unexpected losses. In order to provide assurance that our capital levels are adequate for our risk exposure we test our capital position under several stress scenarios on a bi-annual basis. This analysis is subject to Board of Director review and approval. Our most recent capital stress test was completed in December 2014.

Effective January 1, 2015, the Company is subject to the new regulatory risk-based capital rules adopted by the federal banking agencies implementing Basel III. The most significant changes include higher minimum capital requirements, as the minimum Tier I capital ratio increased from 4.0% to 6.0% and the establishment of a new common equity Tier I capital ratio with a minimum level of 4.5%. Additionally, the new rules improve the quality of capital by providing stricter eligibility criteria for regulatory capital instruments and provide for a phase-in, beginning January 1, 2016, of a capital conservation buffer of 2.5% of risk-weighted assets. This buffer provides a requirement to hold common equity Tier 1 capital above the minimum risk-based capital requirements, resulting in an effective common equity Tier I risk-weighted asset minimum ratio of 7% on a fully phased-in basis.

The Basel III Rules also permit banking organizations with less than $15.0 billion in assets to retain, through a one-time election, the existing treatment for accumulated other comprehensive income, which currently does not affect regulatory capital. The Company elected to retain this treatment, which reduces the volatility of regulatory capital levels.

As of June 30, 2015, First Commonwealth and First Commonwealth Bank met all capital adequacy requirements to which they are subject and was considered well-capitalized under the regulatory rules all on a fully phased in basis. To be considered well

On January 27, 2015, First Commonwealth's Board of Directors authorized a $25.0 million common stock repurchase program. As of June 30, 2015, First Commonwealth had repurchased 2,885,020 shares at an average price of $8.70 per share under this program. This program was completed in May of 2015.

On May 11, 2015, First Commonwealth Bank, the banking subsidiary of First Commonwealth Financial Corporation and Columbus, Ohio based First Community Bank announced the signing of a definitive merger agreement pursuant to which First Commonwealth Bank will acquire First Community Bank in an all-cash deal valued at $14.75 million. First Community Bank has assets of $100 million and operates four branch locations. Upon closing of the transaction, which is expected in October 2015, First Community Bank will merge into First Commonwealth Bank and operate under the First Commonwealth name. First Commonwealth estimates that it will achieve cost saves of approximately 40% of First Community’s operating expenses and that the transaction will be accretive to income in the first full year of operations. First Commonwealth has received all necessary regulatory approvals for completion of the merger.

On July 29, 2015, First Commonwealth Financial Corporation declared a quarterly dividend of $0.07 per share payable on August 21, 2015 to shareholders of record as of August 10, 2015. The timing and amount of future dividends are at the discretion of First Commonwealth's Board of Directors based upon, among other factors, capital levels, asset quality, liquidity and current and projected earnings.

FIRST COMMONWEALTH FINANCIAL CORPORATION AND SUBSIDIARIES

Information appearing in Item 2 of this report under the caption “Market Risk” is incorporated by reference in response to this item.

ITEM 4. Controls and Procedures

We carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and our Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the period covered by this report pursuant to Rule 13a-15 under the Securities Exchange Act of 1934 (the “Exchange Act”). Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures are effective to provide reasonable assurance that the information required to be disclosed in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in applicable rules and forms of the Securities and Exchange Commission.

In addition, our management, including our Chief Executive Officer and Chief Financial Officer, also conducted an evaluation of our internal controls over financial reporting to determine whether any changes occurred during the current fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal controls over financial reporting. No such changes were identified in connection with this evaluation.

ITEM 1. LEGAL PROCEEDINGS

First Commonwealth and certain of its subsidiaries have been named as defendants in various legal actions arising out of the normal course of business.  In the opinion of management, the ultimate resolution of these lawsuits should not have a material adverse effect on First Commonwealth's business, consolidated financial position or results of operations. It is possible, however, that future developments could result in an unfavorable ultimate outcome for or resolution of any one or more of the lawsuits in which First Commonwealth or its subsidiaries are defendants, which may be material to First Commonwealth's results of operations for a particular quarterly reporting period. Litigation is inherently uncertain, and management cannot make assurances that First Commonwealth will prevail in any of these actions, nor can management reasonably estimate the amount of damages that First Commonwealth might incur.

ITEM 1A. RISK FACTORS

There have been no material changes to the risk factors disclosed in our Annual Report on Form 10-K for the fiscal year ended December 31, 2014.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation

Basis of Presentation

The accounting and reporting policies of First Commonwealth Financial Corporation and its subsidiaries (“First Commonwealth” or the “Company”) conform with generally accepted accounting principles in the United States of America (“GAAP”). The preparation of financial statements in conformity with GAAP requires management to make estimates, assumptions and judgments that affect the amounts reported in the financial statements and accompanying notes. Actual realized amounts could differ from those estimates. In the opinion of management, the unaudited interim condensed consolidated financial statements include all adjustments (consisting of only normal recurring adjustments) necessary for a fair presentation of First Commonwealth’s financial position, results of operations, comprehensive income, cash flows and changes in shareholders’ equity as of and for the periods presented.

The results of operations for the six months endedJune 30, 2015 are not necessarily indicative of the results that may be expected for the full year of 2015. These interim financial statements should be read in conjunction with First Commonwealth’s 2014 Annual Report on Form 10-K.

For purposes of reporting cash flows, cash and cash equivalents include cash on hand, amounts due from banks, federal funds sold and interest-bearing bank deposits. Generally, federal funds are sold for one-day periods.

Fair Value Disclosures [Abstract]

Fair Values of Assets and Liabilities

Fair Values of Assets and Liabilities

FASB ASC Topic 820, “Fair Value Measurements and Disclosures”, requires disclosures for non-financial assets and non-financial liabilities, except for items that are recognized or disclosed at fair value in the financial statements on a recurring basis (at least annually). All non-financial assets are included either as a separate line item on the Condensed Consolidated Statements of Financial Condition or in the “Other assets” category of the Condensed Consolidated Statements of Financial Condition. Currently, First Commonwealth does not have any non-financial liabilities to disclose.

FASB ASC Topic 825, “Financial Instruments”, permits entities to irrevocably elect to measure select financial instruments and certain other items at fair value. The unrealized gains and losses are required to be included in earnings each reporting period for the items that fair value measurement is elected. First Commonwealth has elected not to measure any existing financial instruments at fair value under FASB ASC Topic 825; however, in the future we may elect to adopt this guidance for select financial instruments.

In accordance with FASB ASC Topic 820, First Commonwealth groups financial assets and financial liabilities measured at fair value in three levels based on the principal markets in which the assets and liabilities are transacted and the observability of the data points used to determine fair value. These levels are:

• Level 1 – Valuations for assets and liabilities traded in active exchange markets, such as the New York Stock Exchange (“NYSE”). Valuations are obtained from readily available pricing sources for market transactions involving identical assets or liabilities. Level 1 securities include equity holdings comprised of publicly traded bank stocks which were priced using quoted market prices.

• Level 2 – Valuations for assets and liabilities traded in less active dealer or broker markets. Valuations are obtained for identical or comparable assets or liabilities from alternative pricing sources with reasonable levels of price transparency. Level 2 includes Obligations of U.S. Government securities issued by Agencies and Sponsored Enterprises, Obligations of States and Political Subdivisions, corporate securities, FHLB stock, loans held for sale, interest rate derivatives (including interest rate caps, interest rate swaps and risk participation agreements), certain other real estate owned and certain impaired loans.

Level 2 investment securities are valued by a recognized third party pricing service using observable inputs. The model used by the pricing service varies by asset class and incorporates available market, trade and bid information as well as cash flow information when applicable. Because many fixed-income investment securities do not trade on a daily basis, the model uses available information such as benchmark yield curves, benchmarking of like investment securities, sector groupings and matrix pricing. The model will also use processes such as an option adjusted spread to assess the impact of interest rates and to develop prepayment estimates. Market inputs normally used in the pricing model include benchmark yields, reported trades, broker/dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers and reference data including market research publications.

Management validates the market values provided by the third party service by having another recognized pricing service price 100% of the securities on an annual basis and a random sample of securities each quarter, monthly monitoring of variances from prior period pricing and, on a monthly basis, evaluating pricing changes compared to expectations based on changes in the financial markets.

Other investments recorded in the Condensed Consolidated Statements of Financial Condition are comprised of FHLB stock whose estimated fair value is based on its par value. Additional information on FHLB stock is provided in Note 7, “Impairment of Investment Securities.”

Loans held for sale include residential mortgage loans originated for sale in the secondary mortgage market as well as an impaired commercial loan for which sale was considered an appropriate exit strategy. The estimated fair value for the mortgage loans were determined on the basis of rates obtained in the respective secondary market and the estimated fair value of the commercial loan was determined by market bids obtained from potential buyers.

Interest rate derivatives are reported at an estimated fair value utilizing Level 2 inputs and are included in other assets and other liabilities, and consist of interest rate swaps where there is no significant deterioration in the counterparties' (loan customers') credit risk since origination of the interest rate swap as well as interest rate caps and risk participation agreements. First Commonwealth values its interest rate swap and cap positions using a yield curve by taking market prices/rates for an appropriate set of instruments. The set of instruments currently used to determine the U.S. Dollar yield curve includes cash LIBOR rates from overnight to three months, Eurodollar futures contracts and swap rates from three years to thirty years. These yield curves determine the valuations of interest rate swaps. Interest rate derivatives are further described in Note 11, “Derivatives.”

For purposes of potential valuation adjustments to our derivative positions, First Commonwealth evaluates the credit risk of its counterparties as well as our own credit risk. Accordingly, we have considered factors such as the likelihood of default, expected loss given default, net exposures and remaining contractual life, among other things, in determining if any fair value adjustments related to credit risk are required. We review our counterparty exposure quarterly, and when necessary, appropriate adjustments are made to reflect the exposure.

We also utilize this approach to estimate our own credit risk on derivative liability positions. In 2015, we have not realized any losses due to a counterparty's inability to pay any uncollateralized positions.

The estimated fair value for other real estate owned included in Level 2 is determined by either an independent market-based appraisal less estimated costs to sell or an executed sales agreement.

• Level 3 – Valuations for assets and liabilities that are derived from other valuation methodologies, including option pricing models, discounted cash flow models and similar techniques, and not based on market exchange, dealer or broker traded transactions. If the inputs used to provide the valuation are unobservable and/or there is very little, if any, market activity for the security or similar securities, the securities would be considered Level 3 securities. Level 3 valuations incorporate certain assumptions and projections in determining the fair value assigned to such assets or liabilities. The assets included in Level 3 are pooled trust preferred collateralized debt obligations, non-marketable equity investments, certain interest rate derivatives, certain other real estate owned and certain impaired loans.

Our pooled trust preferred collateralized debt obligations are collateralized by the trust preferred securities of individual banks, thrifts and bank holding companies in the United States. There has been little or no active trading in these securities since 2009; therefore, it is more appropriate to determine estimated fair value using a discounted cash flow analysis. Detail on our process for determining the appropriate cash flows for this analysis is provided in Note 7, “Impairment of Investment Securities.” The discount rate applied to the cash flows is determined by evaluating the current market yields for comparable corporate and structured credit products along with an evaluation of the risks associated with the cash flows of the comparable security. Due to the fact that there is no active market for the pooled trust preferred collateralized debt obligations, one key reference point is the market yield for the single issue trust preferred securities issued by banks and thrifts for which there is more activity than for the pooled securities. Adjustments are then made to reflect the credit and structural differences between these two security types.

Management validates the fair value of the pooled trust preferred collateralized debt obligations by monitoring the performance of the underlying collateral, discussing the discount rate, cash flow assumptions and general market trends with the specialized third party and confirming changes in the underlying collateral to the trustee reports. Management’s monitoring of the underlying collateral includes deferrals of interest payments, payment defaults, cures of previously deferred interest payments, any regulatory filings or actions and general news related to the underlying collateral. Management also evaluates fair value changes compared to expectations based on changes in the interest rates used in determining the discount rate and general financial markets.

The estimated fair value of the non-marketable equity investments included in Level 3 is based on par value.

For interest rate derivatives included in Level 3, the fair value incorporates credit risk by considering such factors as likelihood of default and expected loss given default based on the credit quality of the underlying counterparties (loan customers).

In accordance with ASU 2011-4, the following table provides information related to quantitative inputs and assumptions used in Level 3 fair value measurements.

	Fair Value (dollars in thousands)			Valuation Technique	Unobservable Inputs	Range / (weighted average)
Pooled Trust Preferred Securities	$	35,521		Discounted Cash Flow	Probability of default	0% - 100% (16.47%)
					Prepayment rates	0% - 73.65% (5.10%)
					Discount rates	5.25% - 12.00% (a)
Equities	1,920			Par Value	N/A	N/A
Impaired Loans	3,215		(b)	Reserve study	Discount rate	10.00%
					Gas per MCF	$1.88 - $5.27 (c)
					Oil per BBL/d	$55.00 - $90.00 (c)
					NGL per barrel	$15.00 (c)
	520		(b)	Discounted Cash Flow	Discount Rate	1.90%
Other Real Estate Owned	18			Internal Valuation	N/A	N/A

(a) incorporates spread over risk free rate related primarily to credit quality and illiquidity of securities.

(b) the remainder of impaired loans valued using Level 3 inputs are not included in this disclosure as the values of those loans are based on bankruptcy agreement documentation.

(c) unobservable inputs are defined as follows: MCF - million cubic feet; BBL/d - barrels per day; NGL - natural gas liquid.

The significant unobservable inputs used in the fair value measurement of pooled trust preferred securities are the probability of default, discount rates and prepayment rates. Significant increases in the probability of default or discount rate used would result in a decrease in the estimated fair value of these securities, while decreases in these variables would result in higher fair value measurements. In general, a change in the assumption of probability of default is accompanied by a directionally similar change in the discount rate. In most cases, increases in the prepayment rate assumptions would result in a higher estimated fair value for these securities while decreases would provide for a lower value. The direction of this change is somewhat dependent on the structure of the investment and the amount of the investment tranches senior to our position.

The discount rate is the significant unobservable input used in the fair value measurement of impaired loans. Significant increases in this rate would result in a decrease in the estimated fair value of the loans, while a decrease in this rate would result in a higher fair value measurement. Other unobservable inputs in the fair value measurement of impaired loans relate to gas, oil and natural gas prices. Increases in these prices would result in an increase in the estimated fair value of the loans, while a decrease in these prices would result in a lower fair value measurement.

During the six months endedJune 30, 2015 and 2014, there were no transfers between fair value Levels 1 and 2. During the six months ended June 30, 2015, there were no transfers between fair value Levels 2 and 3. However, $3.0 million of loans were transferred into Level 3 from Level 2 during the six months ended June 30, 2014 due to the loans being transferred to a held for sale status. The loans transferred and subsequently sold related to three nonperforming loan relationships for which this was determined to be the appropriate exit strategy. There were no gains or losses included in earnings for the periods presented that are attributable to the change in realized gains (losses) relating to assets held at June 30, 2015 and 2014.

For the three months endedJune 30, changes in Level 3 assets and liabilities measured at fair value on a recurring basis are summarized as follows:

During the three months endedJune 30, 2015 and 2014, there were no transfers between fair value Levels 1 and 2. During the three months ended June 30, 2015, there were no transfers between fair value Levels 2 and 3. However, $2.3 million of loans were transferred into Level 3 from Level 2 during the three months ended June 30, 2014 due to the loans being transferred to a held for sale status. The loans transferred and subsequently sold related to three nonperforming loan relationships for which this was determined to be the appropriate exit strategy.

The tables below present the balances of assets measured at fair value on a non-recurring basis at:

	June 30, 2015

The following losses were realized on the assets measured on a nonrecurring basis:

	For the Three Months Ended June 30,						For the Six Months Ended June 30,

Total losses	$	(1,508	)	$	(3,748	)	$	(1,997	)	$	(3,817	)

Impaired loans over $100 thousand are individually reviewed to determine the amount of each loan considered to be at risk of non-collection. The fair value for impaired loans that are collateral based is determined by reviewing real property appraisals, equipment valuations, accounts receivable listings and other financial information. A discounted cash flow analysis is performed to determine fair value for impaired loans when an observable market price or a current appraisal is not available. For real estate secured loans, First Commonwealth’s loan policy requires updated appraisals be obtained at least every twelve months on all impaired loans with balances of $250 thousand and over. For real estate secured loans with balances under $250 thousand, we rely on broker price opinions. For non-real estate secured assets, the Company normally relies on third party valuations specific to the collateral type.

The fair value for other real estate owned determined by either an independent market-based appraisal less estimated costs to sell or an executed sales agreement is classified as Level 2. The fair value for other real estate owned determined using an internal valuation is classified as Level 3. Other real estate owned has a book cost of $6.5 million as of June 30, 2015 and consisted primarily of commercial real estate properties in Pennsylvania. We review whether events and circumstances subsequent to a transfer to other real estate owned have occurred that indicate the balance of those assets may not be recoverable. If events and circumstances indicate further impairment we will record a charge to the extent that the carrying value of the assets exceed their fair values, less estimated cost to sell, as determined by valuation techniques appropriate in the circumstances.

Certain other assets and liabilities, including goodwill and core deposit intangibles, are measured at fair value on a non-recurring basis; that is, the instruments are not measured at fair value on an ongoing basis but are subject to fair value adjustments only in certain circumstances. Additional information related to goodwill is provided in Note 12, “Goodwill.” There were no other assets or liabilities measured at fair value on a non-recurring basis during the six months endedJune 30, 2015.

FASB ASC 825-10, “Transition Related to FSP FAS 107-1” and APB 28-1, “Interim Disclosures about Fair Value of Financial Instruments,” requires disclosure of the fair value of financial assets and financial liabilities, including those financial assets and financial liabilities that are not measured and reported at fair value on a recurring basis or non-recurring basis. The methodologies for estimating the fair value of financial assets and financial liabilities that are measured at fair value on a recurring or non-recurring basis are as discussed above. The methodologies for other financial assets and financial liabilities are discussed below.

Cash and due from banks and interest-bearing bank deposits: The carrying amounts for cash and due from banks and interest-bearing bank deposits approximate the estimated fair values of such assets.

Securities: Fair values for securities available for sale and held to maturity are based on quoted market prices, if available. If quoted market prices are not available, fair values are based on quoted market prices of comparable instruments. Pooled trust preferred collateralized debt obligations values are derived from other valuation methodologies, including option pricing models, discounted cash flow models and similar techniques, and not based on market exchange, dealer or broker traded transactions. These valuations incorporate certain assumptions and projections in determining the fair value assigned to each instrument. The carrying value of other investments, which includes FHLB stock, is considered a reasonable estimate of fair value.

Loans: The fair values of all loans are estimated by discounting the estimated future cash flows using interest rates currently offered for loans with similar terms to borrowers of similar credit quality adjusted for past due and nonperforming loans, which is not an exit price under FASB ASC Topic 820, “Fair Value Measurements and Disclosures.”

Loans Held for Sale: The estimated fair value of loans held for sale is based on market bids obtained from potential buyers.

Off-balance sheet instruments: Many of First Commonwealth’s off-balance sheet instruments, primarily loan commitments and standby letters of credit, are expected to expire without being drawn upon; therefore, the commitment amounts do not necessarily represent future cash requirements. FASB ASC Topic 460, “Guarantees” clarified that a guarantor is required to recognize, at the inception of a guarantee, a liability for the fair value of the obligation undertaken in issuing the guarantee. The carrying amount and fair value for standby letters of credit was $0.2 million at June 30, 2015 and December 31, 2014, respectively. See Note 5, “Commitments and Contingent Liabilities,” for additional information.

Deposit liabilities: The estimated fair value of demand deposits, savings accounts and money market deposits is the amount payable on demand at the reporting date because of the customers’ ability to withdraw funds immediately. The carrying value of variable rate time deposit accounts and certificates of deposit approximate their fair values at the report date. Also, fair values of fixed rate time deposits for both periods are estimated by discounting the future cash flows using interest rates currently being offered and a schedule of aggregated expected maturities.

Short-term borrowings: The fair values of borrowings from the FHLB were estimated based on the estimated incremental borrowing rate for similar types of borrowings. The carrying amounts of other short-term borrowings such as federal funds purchased and securities sold under agreement to repurchase were used to approximate fair value due to the short-term nature of the borrowings.

Long-term debt and subordinated debt: The fair value of long-term debt and subordinated debt is estimated by discounting the future cash flows using First Commonwealth’s estimate of the current market rate for similar types of borrowing arrangements or an announced redemption price.

The following table presents carrying amounts and fair values of First Commonwealth’s financial instruments:

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivatives

Derivatives Not Designated as Hedging Instruments

First Commonwealth is a party to interest rate derivatives that are not designated as hedging instruments. These derivatives relate to interest rate swaps that First Commonwealth enters into with customers to allow customers to convert variable rate loans to a fixed rate. First Commonwealth pays interest to the customer at a floating rate on the notional amount and receives interest from the customer at a fixed rate for the same notional amount. At the same time the interest rate swap is entered into with the customer, an offsetting interest rate swap is entered into with another financial institution. First Commonwealth pays the other financial institution interest at the same fixed rate on the same notional amount as the swap entered into with the customer, and receives interest from the financial institution for the same floating rate on the same notional amount.

The changes in the fair value of the swaps offset each other, except for the credit risk of the counterparties, which is determined by taking into consideration the risk rating, probability of default and loss given default for all counterparties.

We have fifteen risk participation agreements with financial institution counterparties for interest rate swaps related to loans in which we are a participant. The risk participation agreements provide credit protection to the financial institution should the borrower fail to perform on its interest rate derivative contract with the financial institution. We have three risk participation agreements with financial institution counterparties for interest rate swaps related to loans in which we are the lead bank. The risk participation agreement provides credit protection to us should the borrower fail to perform on its interest rate derivative contract with us.

First Commonwealth is also party to interest rate caps that are not designated as hedging instruments. These derivatives relate to contracts that First Commonwealth enters into with loan customers that provides a maximum interest rate on their variable rate loan. At the same time the interest rate cap is entered into with the customer, First Commonwealth enters into an offsetting interest rate cap with another financial institution. The notional amount and maximum interest rate on both interest cap contracts are identical.

The fee received, less the estimate of the loss for the credit exposure, was recognized in earnings at the time of the transaction.

Derivatives Designated as Hedging Instruments

The Company has entered into four interest rate swap contracts that were designated as cash flow hedges. The interest rate swaps have a total notional amount of $200.0 million, $85.0 million with an original maturity of three years and $115.0 million with and original maturity of four years. The Company's risk management objective for these hedges is to reduce its exposure to variability in expected future cash flows related to interest payments on commercial loans benchmarked to the 1-month LIBOR rate. Therefore, the interest rate swaps convert the interest payments on the first $200.0 million of 1-month LIBOR based commercial loans into fixed rate payments.

The periodic net settlement of interest rate swaps is recorded as an adjustment to Interest and fees on loans in the Condensed Consolidated Statements of Income. For the six months endedJune 30, 2015, there was a $0.9 million impact on interest income as a result of these interest rate swaps. Changes in the fair value of the effective portion of cash flow hedges are reported in OCI. When the cash flows associated with the hedged item are realized, the gain or loss included in OCI is recognized in "Interest and fees on loans," the same line item in the Condensed Consolidated Statements of Income as the income on the hedged items. The cash flow hedges were highly effective at June 30, 2015, and December 31, 2014, and changes in the fair value attributed to hedge ineffectiveness were not material.

The following table depicts the credit value adjustment recorded related to the notional amount of derivatives outstanding as well as the notional amount of risk participation agreements participated to other banks:

Impairment of Investment Securities

Impairment of Investment Securities Disclosure [Abstract]

Impairment of Investment Securities

Impairment of Investment Securities

Securities Available for Sale and Held to Maturity

As required by FASB ASC Topic 320, “Investments – Debt and Equity Securities,” credit related other-than-temporary impairment on debt securities is recognized in earnings, while non-credit related other-than-temporary impairment on debt securities not expected to be sold is recognized in OCI. During the six months endedJune 30, 2015 and 2014, no other-than-temporary impairment charges were recognized.

First Commonwealth utilizes the specific identification method to determine the net gain or loss on debt securities and the average cost method to determine the net gain or loss on equity securities.

We review our investment portfolio on a quarterly basis for indications of impairment. This review includes analyzing the length of time and the extent to which the fair value has been lower than the cost, the financial condition and near-term prospects of the issuer, including any specific events which may influence the operations of the issuer and whether we are more likely than not to sell the security. We evaluate whether we are more likely than not to sell debt securities based upon our investment strategy for the particular type of security and our cash flow needs, liquidity position, capital adequacy, tax position and interest rate risk position. In addition, the risk of future other-than-temporary impairment may be influenced by additional bank failures, weakness in the U.S. economy, changes in real estate values and additional interest deferrals in our pooled trust preferred collateralized debt obligations. Our pooled trust preferred collateralized debt obligations are beneficial interests in securitized financial assets within the scope of FASB ASC Topic 325, “Investments – Other,” and are therefore evaluated for other-than-temporary impairment using management’s best estimate of future cash flows. If these estimated cash flows indicate that it is probable that an adverse change in cash flows has occurred, then other-than-temporary impairment would be recognized in accordance with FASB ASC Topic 320. There is a risk that First Commonwealth will record other-than-temporary impairment charges in the future. See Note 10, “Fair Values of Assets and Liabilities,” for additional information.

The following table presents the gross unrealized losses and estimated fair values at June 30, 2015 for both available for sale and held to maturity securities by investment category and time frame for which securities have been in a continuous unrealized loss position:

At June 30, 2015, fixed income securities issued by U.S. Government-sponsored enterprises comprised 57% of total unrealized losses due to changes in market interest rates. Pooled trust preferred collateralized debt obligations accounted for 41% of the unrealized losses primarily due to the illiquid market for this investment type. Obligations of U.S. Government agencies and obligations of state and political subdivisions account for the remaining 2% of total unrealized losses as a result of changes in market interest rates. At June 30, 2015, there are 70 debt securities in an unrealized loss position.

As of June 30, 2015, our corporate securities had an amortized cost and an estimated fair value of $1.9 million and $2.3 million, respectively. As of December 31, 2014, our corporate securities had an amortized cost and estimated fair value of $6.7 million and $7.3 million, respectively. Corporate securities are comprised of single issue trust preferred securities issued primarily by large regional banks. There were no corporate securities in an unrealized loss position as of June 30, 2015 and December 31, 2014. When unrealized losses exist on these investments, management reviews each of the issuer’s asset quality, earnings trends and capital position, to determine whether issues in an unrealized loss position were other-than-temporarily impaired. All interest payments on the corporate securities are being made as contractually required.

As of June 30, 2015, the book value of our pooled trust preferred collateralized debt obligations totaled $41.7 million with an estimated fair value of $35.5 million, which includes securities comprised of 275 banks and other financial institutions. All of our pooled securities are mezzanine tranches, three of which now have no senior class remaining in the issue. The credit rating on all of our issues are below investment grade. At the time of initial issue, the subordinated tranches ranged in size from approximately 7% to 35% of the total principal amount of the respective securities and no more than 5% of any pooled security consisted of a security issued by any one institution. As of June 30, 2015, after taking into account management’s best estimates of future interest deferrals and defaults, four of our securities had no excess subordination in the tranches we own and five of our securities had excess subordination which ranged from 11% to 84% of the current performing collateral.

The following table provides information related to our pooled trust preferred collateralized debt obligations as of June 30, 2015:

Lack of liquidity in the market for trust preferred collateralized debt obligations, below investment grade credit ratings and market uncertainties related to the financial industry are factors contributing to the impairment on these securities.

All of the Company's pooled trust preferred securities are included in the non-exclusive list issued by the regulatory agencies and therefore are not considered covered funds under the Volcker Rule.

On a quarterly basis we evaluate our debt securities for other-than-temporary impairment. During the six months endedJune 30, 2015 and 2014, there were no credit related other-than-temporary impairment charges recognized on our pooled trust preferred collateralized debt obligations. When evaluating these investments, we determine a credit-related portion and a non-credit related portion of other-than-temporary impairment. The credit related portion is recognized in earnings and represents the difference between book value and the present value of future cash flows. The non-credit related portion is recognized in OCI and represents the difference between the fair value of the security and the amount of credit-related impairment. A discounted cash flow analysis provides the best estimate of credit-related other-than-temporary impairment for these securities.

Additional information related to the discounted cash flow analysis follows:

Our pooled trust preferred collateralized debt obligations are measured for other-than-temporary impairment within the scope of FASB ASC Topic 325 by determining whether it is probable that an adverse change in estimated cash flows has occurred. Determining whether there has been an adverse change in estimated cash flows from the cash flows previously projected involves comparing the present value of remaining cash flows previously projected against the present value of the cash flows estimated at June 30, 2015. We consider the discounted cash flow analysis to be our primary evidence when determining whether credit related other-than-temporary impairment exists.

Results of a discounted cash flow test are significantly affected by other variables, such as the estimate of future cash flows, credit worthiness of the underlying banks and determination of probability of default of the underlying collateral. The following provides additional information for each of these variables:

• Estimate of Future Cash Flows – Cash flows are constructed in an INTEX cash flow model which includes each deal’s structural features. Projected cash flows include prepayment assumptions, which are dependent on the issuer's asset size and coupon rate. For collateral issued by financial institutions over $15 billion in asset size with a coupon over 7%, a 100% prepayment rate is assumed. Financial institutions over $15 billion with a coupon of 7% or under are assigned a prepayment rate of 40% for two years and 2% thereafter. Financial institutions with assets between $2 billion and $15 billion with coupons over 7% are assigned a 5% prepayment rate. For financial institutions below $2 billion, if the coupon is over 10%, a prepayment rate of 5% is assumed and for all other issuers, there is no prepayment assumption incorporated into the cash flows. The modeled cash flows are then used to estimate if all the scheduled principal and interest payments of our investments will be returned.

• Credit Analysis – A quarterly credit evaluation is performed for each of the 275 banks comprising the collateral across the various pooled trust preferred securities. Our credit evaluation considers all evidence available to us and includes the nature of the issuer’s business, its years of operating history, corporate structure, loan composition, loan concentrations, deposit mix, asset growth rates, geographic footprint and local economic environment. Our analysis focuses on profitability, return on assets, shareholders’ equity, net interest margin, credit quality ratios, operating efficiency, capital adequacy and liquidity.

• Probability of Default – A probability of default is determined for each bank and is used to calculate the expected impact of future deferrals and defaults on our expected cash flows. Each bank in the collateral pool is assigned a probability of default for each year until maturity. Currently, any bank that is in default is assigned a 100% probability of default and a 0% projected recovery rate. All other banks in the pool are assigned a probability of default based on their unique credit characteristics and market indicators with a 10% projected recovery rate. For the majority of banks currently in deferral we assume the bank continues to defer and will eventually default and, therefore, a 100% probability of default is assigned. However, for some deferring collateral there is the possibility that they become current on interest or principal payments at some point in the future and in those cases a probability that the deferral will ultimately cure is assigned. The probability of default is updated quarterly. As of June 30, 2015, default probabilities for performing collateral ranged from 0.33% to 75%.

Our credit evaluation provides a basis for determining deferral and default probabilities for each underlying piece of collateral. Using the results of the credit evaluation, the next step of the process is to look at pricing of senior debt or credit default swaps for the issuer (or where such information is unavailable, for companies having similar credit profiles as the issuer). The pricing of these market indicators provides the information necessary to determine appropriate default probabilities for each bank.

In addition to the above factors, our evaluation of impairment also includes a stress test analysis which provides an estimate of excess subordination for each tranche. We stress the cash flows of each pool by increasing current default assumptions to the level of defaults that results in an adverse change in estimated cash flows. This stressed breakpoint is then used to calculate excess subordination levels for each pooled trust preferred security. The results of the stress test allow management to identify those pools that are at a greater risk for a future break in cash flows so that we can monitor banks in those pools more closely for potential deterioration of credit quality.

Our cash flow analysis as of June 30, 2015, indicates that no credit-related other-than-temporary impairment has occurred on our pooled trust preferred securities during the six months endedJune 30, 2015. Based upon the analysis performed by management, it is probable that four of our pooled trust preferred securities will experience principal and interest shortfalls and therefore appropriate other-than-temporary charges were recorded in prior periods. These securities are identified in the table on page 16 with 0% “Excess Subordination as a Percentage of Current Performing Collateral.” For the remaining securities listed in that table, our analysis as of June 30, 2015 indicates it is probable that we will collect all contractual principal and interest payments. For four of those securities, PreTSL IX, PreTSL XIII, PreTSL XIV and MMCap I, other-than-temporary impairment charges were recorded in prior periods; however, due to improvement in the expected cash flows of these securities, it is now probable that all contractual payments will be received.

During 2008, 2009 and 2010, other-than-temporary impairment charges were recognized on all of our pooled trust preferred securities, except for PreTSL IV. Our cash flow analysis as of June 30, 2015, for all of these impaired securities indicates that it is now probable we will collect principal and interest in excess of what was estimated at the time other-than-temporary impairment charges were recorded. This change can be attributed to improvement in the underlying collateral for these securities and has resulted in the present value of estimated future principal and interest payments exceeding the securities' current book value. The excess for each bond of the present value of future cash flows over our current book value ranges from 21% to 141% and will be recognized as an adjustment to yield over the remaining life of these securities. The excess subordination recognized as an adjustment to yield is reflected in the following table as increases in cash flows expected to be collected.

The following table provides a cumulative roll forward of credit losses recognized in earnings for debt securities held and not intended to be sold:

	For the Three Months Ended June 30,						For the Six Months Ended June 30,
	2015			2014			2015			2014

Balance, ending	$	25,366		$	26,842		$	25,366		$	26,842

(a) The beginning balance represents credit related losses included in other-than-temporary impairment charges recognized on debt securities in prior periods.

(b) Represents the increase in cash flows recognized in interest income during the period.

In the first six months of 2015 and 2014, no other-than-temporary impairment charges were recorded on equity securities. On a quarterly basis, management evaluates equity securities for other-than-temporary impairment by reviewing the severity and duration of decline in estimated fair value, research reports, analysts’ recommendations, credit rating changes, news stories, annual reports, regulatory filings, impact of interest rate changes and other relevant information. As of June 30, 2015 and 2014, there were no equity securities in an unrealized loss position.

Other Investments

As a member of the Federal Home Loan Bank ("FHLB"), First Commonwealth is required to purchase and hold stock in the FHLB to satisfy membership and borrowing requirements. The level of stock required to be held is dependent on the amount of First Commonwealth's mortgage-related assets and outstanding borrowings with the FHLB. This stock is restricted in that it can only be sold to the FHLB or to another member institution, and all sales of FHLB stock must be at par. As a result of these restrictions, FHLB stock is unlike other investment securities insofar as there is no trading market for FHLB stock and the transfer price is determined by FHLB membership rules and not by market participants. As of June 30, 2015 and December 31, 2014, our FHLB stock totaled $53.3 million and $44.5 million, respectively, and is included in “Other investments” on the Condensed Consolidated Statements of Financial Condition.

FHLB stock is held as a long-term investment and its value is determined based on the ultimate recoverability of the par value. First Commonwealth evaluates impairment quarterly and has concluded that the par value of its investment in FHLB stock will be recovered. Accordingly, no impairment charge was recorded on these securities during the six months ended June 30, 2015.

Commitments and Contingent Liabilities

Commitments and Contingent Liabilities

Commitments and Letters of Credit

Standby letters of credit and commercial letters of credit are conditional commitments issued by First Commonwealth to guarantee the performance of a customer to a third party. The contract or notional amount of these instruments reflects the maximum amount of future payments that First Commonwealth could be required to pay under the guarantees if there were a total default by the guaranteed parties, without consideration of possible recoveries under recourse provisions or from collateral held or pledged. In addition, many of these commitments are expected to expire without being drawn upon; therefore, the total commitment amounts do not necessarily represent future cash requirements.

The following table identifies the notional amount of those instruments at:

	June 30, 2015		December 31, 2014
	(dollars in thousands)
Financial instruments whose contract amounts represent credit risk:
Commitments to extend credit	$	1,610,767	$	1,635,948
Financial standby letters of credit	26,287		36,075
Performance standby letters of credit	25,878		25,915
Commercial letters of credit	2,146		2,611

The notional amounts outstanding as of June 30, 2015 include amounts issued in 2015 of $7.8 million in financial standby letters of credit and $1.8 million in performance standby letters of credit. There have been no commercial letters of credit issued during 2015. A liability of $0.2 million has been recorded as of June 30, 2015 and December 31, 2014, which represents the estimated fair value of letters of credit issued. The fair value of letters of credit is estimated based on the unrecognized portion of fees received at the time the commitment was issued.

Unused commitments and letters of credit provide exposure to future credit loss in the event of nonperformance by the borrower or guaranteed parties. Management’s evaluation of the credit risk related to these commitments resulted in the recording of a liability of $3.8 million as of June 30, 2015 and $3.1 million as of December 31, 2014. This liability is reflected in "Other liabilities" in the Condensed Consolidated Statements of Financial Condition. The credit risk evaluation incorporated probability of default, loss given default and estimated utilization for the next twelve months for each loan category and the letters of credit.

Legal Proceedings

There are no material legal proceedings to which First Commonwealth or its subsidiaries are a party, or of which their property is the subject, except proceedings which arise in the normal course of business and, in the opinion of management, will not have a material adverse effect on the consolidated operations, financial position, comprehensive income or cash flow of First Commonwealth or its subsidiaries.

Mortgage backed securities include mortgage backed obligations of U.S. Government agencies and obligations of U.S. Government-sponsored enterprises. These obligations have contractual maturities ranging from less than one year to approximately 30 years with lower anticipated lives to maturity due to prepayments. All mortgage backed securities contain a certain amount of risk related to the uncertainty of prepayments of the underlying mortgages. Interest rate changes have a direct impact upon prepayment speeds; therefore, First Commonwealth uses computer simulation models to test the average life and yield volatility of all mortgage backed securities under various interest rate scenarios to monitor the potential impact on earnings and interest rate risk positions.

Expected maturities will differ from contractual maturities because issuers may have the right to call or repay obligations with or without call or prepayment penalties. Other fixed income securities within the portfolio also contain prepayment risk.

Credit Quality Information

As part of the on-going monitoring of credit quality within the loan portfolio, the following credit worthiness categories are used in grading our loans:

Pass Acceptable levels of risk exist in the relationship. Includes all loans not classified as OAEM, substandard or doubtful.

Other Assets Especially Mentioned (OAEM) Potential weaknesses that deserve management’s close attention. The potential weaknesses may result in deterioration of the repayment prospects or weaken the Company’s credit position at some future date. The credit risk may be relatively minor, yet constitute an undesirable risk in light of the circumstances surrounding the specific credit. No loss of principal or interest is expected.

Substandard Well-defined weakness or a weakness that jeopardizes the repayment of the debt. A loan may be classified as substandard as a result of deterioration of the borrower’s financial condition and repayment capacity. Loans for which repayment plans have not been met or collateral equity margins do not protect the Company may also be classified as substandard.

Doubtful Loans with the characteristics of substandard loans with the added characteristic that collection or liquidation in full, on the basis of presently existing facts and conditions, is highly improbable.

The use of creditworthiness categories to grade loans permits management’s use of migration analysis to estimate a portion of credit risk. The Company’s internal creditworthiness grading system provides a measurement of credit risk based primarily on an evaluation of the borrower’s cash flow and collateral. Movement between these rating categories provides a predictive measure of credit losses and therefore assists in determining the appropriate level for the loan loss reserves. Category ratings are reviewed each quarter, at which time management analyzes the results, as well as other external statistics and factors related to loan performance. Loans that migrate towards higher risk rating levels generally have an increased risk of default, whereas loans that migrate toward lower risk ratings generally will result in a lower risk factor being applied to those related loan balances.

The following tables represent our credit risk profile by creditworthiness:

Portfolio Risks

The credit quality of our loan portfolio can potentially represent significant risk to our earnings, capital, regulatory agency relationships, investment community reputation and shareholder returns. First Commonwealth devotes a substantial amount of resources managing this risk primarily through our credit administration department that develops and administers policies and procedures for underwriting, maintaining, monitoring and collecting activities. Credit administration is independent of lending departments and oversight is provided by the credit committee of the First Commonwealth Board of Directors.

Criticized loans have been evaluated when determining the appropriateness of the allowance for credit losses, which we believe is adequate to absorb losses inherent to the portfolio as of June 30, 2015. However, changes in economic conditions, interest rates, borrower financial condition, delinquency trends or previously established fair values of collateral factors could significantly change those judgmental estimates.

Age Analysis of Past Due Loans by Segment

The following tables delineate the aging analysis of the recorded investments in past due loans as of June 30, 2015 and December 31, 2014. Also included in these tables are loans that are 90 days or more past due and still accruing because they are well-secured and in the process of collection.

Nonaccrual Loans

The previous tables summarize nonaccrual loans by loan segment. The Company generally places loans on nonaccrual status when the full and timely collection of interest or principal becomes uncertain, when part of the principal balance has been charged off and no restructuring has occurred, or the loans reach a certain number of days past due. Generally, loans 90 days or more past due are placed on nonaccrual status, except for consumer loans, which are placed in nonaccrual status at 150 days past due.

When a loan is placed on nonaccrual, the accrued unpaid interest receivable is reversed against interest income and all future payments received are applied as a reduction to the loan principal. Generally, the loan is returned to accrual status when (a) all delinquent interest and principal becomes current under the terms of the loan agreement or (b) the loan is both well-secured and in the process of collection and collectability is no longer in doubt.

Impaired Loans

Management considers loans to be impaired when, based on current information and events, it is determined that the Company will not be able to collect all amounts due according to the loan contract, including scheduled interest payments. Determination of impairment is treated the same across all loan categories. When management identifies a loan as impaired, the impairment is measured based on the present value of expected future cash flows, discounted at the loan’s effective interest rate, except when the sole source for repayment of the loan is the operation or liquidation of collateral. When the loan is collateral dependent, the appraised value less estimated cost to sell is utilized. If management determines the value of the impaired loan is less than the recorded investment in the loan, impairment is recognized through an allowance estimate or a charge-off to the allowance. Troubled debt restructured loans on accrual status are also considered to be impaired loans.

When the ultimate collectability of the total principal of an impaired loan is in doubt and the loan is on nonaccrual status, all payments are applied to principal under the cost recovery method. When the ultimate collectability of the total principal of an impaired loan is not in doubt and the loan is on nonaccrual status, contractual interest is credited to interest income when received under the cash basis method.

There were $2.4 million of impaired loans held for sale at June 30, 2015. These loans were transferred to held for sale status in the first quarter of 2015 and were sold in July 2015, at which time a gain of $0.4 million was recognized. There were no impaired loans held for sale at December 31, 2014. During the six months endedJune 30, 2014, $3.1 million of impaired loans were sold, resulting in the recognition of a gain of $0.1 million. No gains were recognized on the sale of impaired loans during the six months endedJune 30, 2015.

Significant nonaccrual loans as of June 30, 2015, include the following:

• $7.4 million relationship of commercial and real estate loans to a local water facility construction company. These loans were originated from 2009 to 2013 and were placed in nonaccrual status during the fourth quarter of 2014. During the six months endedJune 30, 2015, charge-offs of $2.3 million related to this relationship were recorded. A valuation of the collateral was completed during the first quarter of 2015.

• $5.9 million relationship of commercial industrial loans to a local energy company. These loans were originated from 2008 to 2011 and were placed in nonaccrual status during the third quarter of 2013. Two of these loans were modified resulting in TDR classification: one loan totaling $2.3 million was modified in 2012, and the other loan totaling $3.0 million was modified in 2014. During the six months endedJune 30, 2015, charge-offs of $3.3 million related to this relationship were recorded. A valuation of the collateral was updated during the first quarter of 2015.

The following tables include the recorded investment and unpaid principal balance for impaired loans with the associated allowance amount, if applicable, as of June 30, 2015 and December 31, 2014. Also presented are the average recorded investment in impaired loans and the related amount of interest recognized while the loan was considered impaired. Average balances are calculated using month-end balances of the loans for the period reported and are included in the table below based on their period-end allowance position.

Accounting Changes and Error Corrections [Abstract]

New Accounting Pronouncements

New Accounting Pronouncements

In January 2015, the FASB issued ASU No. 2015-01, "Income Statement - Extraordinary and Unusual Items (Subtopic 225-20)," which finalizes Proposed ASU No. 2014-220, and eliminates the concept of extraordinary items from U.S. GAAP. Accordingly, this ASU eliminates FASB ASC Subtopic 225-20, "Income Statement - Extraordinary and Unusual Items", which, until now, required that an entity separately classify, present, and disclose extraordinary events and transactions. This ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. The adoption of this ASU is not expected to have a material impact on First Commonwealth’s financial condition or results of operations.

Goodwill Disclosure [Abstract]

Goodwill

Goodwill

FASB ASC Topic 350-20, “Intangibles – Goodwill and Other” requires an annual valuation of the fair value of a reporting unit that has goodwill and a comparison of the fair value to the book value of equity to determine whether the goodwill has been impaired. Goodwill is also required to be tested on an interim basis if an event or circumstance indicates that it is more likely than not that an impairment loss has been incurred. When triggering events or circumstances indicate that goodwill testing is required, an assessment of qualitative factors can be completed before performing the two step goodwill impairment test. ASU 2011-8 provides that if an assessment of qualitative factors determines it is more likely than not that the fair value of a reporting unit exceeds its carrying amount, then the two step goodwill impairment test is not required.

We consider First Commonwealth to be one reporting unit. The carrying amount of goodwill as of June 30, 2015 and December 31, 2014 was $161.4 million. No impairment charges on goodwill or other intangible assets were incurred in 2015 or 2014.

We test goodwill for impairment as of November 30th each year and again at any quarter-end if any material events occur during a quarter that may affect goodwill.

As of June 30, 2015, goodwill was not considered impaired; however, changing economic conditions that may adversely affect our performance, the fair value of our assets and liabilities, or our stock price could result in impairment, which could adversely affect earnings in future periods. Management will continue to monitor events that could impact this conclusion in the future.
