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 “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, cash flows and changes in shareholders’ equity as of and for the periods presented.

The results of operations for the nine months endedSeptember 30, 2014 are not necessarily indicative of the results that may be expected for the full year of 2014. These interim financial statements should be read in conjunction with First Commonwealth’s 2013 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 5 Variable Interest Entities

As defined by Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 810-10, a Variable Interest Entity (“VIE”) is a corporation, partnership, trust or any other legal structure used for business purposes that either (a) does not have equity investors with voting rights or (b) has equity investors that do not provide sufficient financial resources for the entity to support its activities. Under ASC 810-10, an entity that holds a variable interest in a VIE is required to consolidate the VIE if the entity is deemed to be the primary beneficiary, which generally means it is subject to a majority of the risk of loss from the VIE’s activities, is entitled to receive a majority of the entity’s residual returns, or both.

First Commonwealth’s VIEs are evaluated under the guidance included in FASB Accounting Standards Update (“ASU”) 2009-17. These VIEs include qualified affordable housing projects that First Commonwealth has invested in as part of its community reinvestment initiatives. We periodically assess whether or not our variable interests in the VIE, based on qualitative analysis, provide us with a controlling interest in the VIE. The analysis includes an assessment of the characteristics of the VIE. We do not have a controlling financial interest in the VIE, which would require consolidation of the VIE, as we do not have the following characteristics: (1) the power to direct the activities that most significantly impact the VIE’s economic performance; and (2) the obligation to absorb losses or the right to receive benefits from the VIE that could potentially be significant to the VIE.

First Commonwealth’s maximum potential exposure is equal to its carrying value and is summarized in the table below:

Note 6 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:

	September 30, 2014		December 31, 2013
	(dollars in thousands)
Financial instruments whose contract amounts represent credit risk:
Commitments to extend credit	$	1,644,486	$	1,571,987
Financial standby letters of credit	29,379		38,121
Performance standby letters of credit	26,210		32,441
Commercial letters of credit	2,405		—

The notional amounts outstanding as of September 30, 2014 include amounts issued in 2014 of $0.3 million in financial standby letters of credit and $0.8 million in performance standby letters of credit. There were $0.2 million commercial letters of credit issued during 2014. A liability of $0.1 million has been recorded as of September 30, 2014 and December 31, 2013, 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 $2.9 million as of September 30, 2014 and $3.2 million as of December 31, 2013. 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

Market Rate Savings IRA Litigation

McGrogan v. First Commonwealth Bank was filed as a class action on January 12, 2009, in the Court of Common Pleas of Allegheny County, Pennsylvania. The action alleges that First Commonwealth Bank (the “Bank”) promised class members a minimum interest rate of 8% on its IRA Market Rate Savings Account for as long as the class members kept their money on deposit in the IRA account. The class asserted that the Bank committed fraud, breached its modified contract with the class members, and violated the Pennsylvania Unfair Trade Practice and Consumer Protection Law ("UTPCPL") when it resigned as custodian of the IRA Market Rate Savings Accounts in 2008 and offered the class members a roll-over IRA account with a 3.5% interest rate. Plaintiffs sought monetary damages for the alleged breach of contract, punitive damages for the alleged fraud and Unfair Trade Practice and Consumer Protection Law violations and attorney’s fees. The court ruled that the IRA contract only guaranteed the 8% return until the 90-day or 18-month maturity of each instrument. The court granted class certification as to the breach of modified contract claim and denied class certification as to the fraud and Pennsylvania Unfair Trade Practice and Consumer Protection Law claims. The breach of contract claim was predicated upon a letter sent to customers in 1998 which reversed an earlier decision by the Bank to reduce the rate paid on the accounts. The letter stated, in relevant part, “This letter will serve as notification that a decision has been made to re-establish the rate on your account to eight percent (8)%. This rate will be retroactive to your most recent maturity date and will continue going forward on deposits presently in the account and on annual additions.” On August 30, 2012, the Court entered an order granting the Bank’s motion for summary judgment and dismissed the class action claims. The Court found that the Bank retained the right to resign as custodian of the accounts and that the act of resigning as custodian and closing the accounts did not breach the terms of the underlying IRA contract. On appeal, the Superior Court affirmed the denial of class certification to the claims of fraud in the execution and violation of the UTPCPL. The Superior Court found that none of the other issues were ripe for appeal. Jurisdiction was returned to the Court of Common Pleas where the individual fraud and UTPCPL claims of Mr. and Mrs. McGrogan are pending. Plaintiffs filed their pretrial statement on June 16, 2014, seeking $0.5 million in damages for the McGrogans and $0.8 million for their adult children beneficiaries. The Bank considers these damage claims exaggerated and otherwise invalid. The Bank has filed a

11

FIRST COMMONWEALTH FINANCIAL CORPORATION AND SUBSIDIARIES

ITEM 1. Financial Statements and Supplementary Data

NOTES TO THE UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Continued)

motion for summary judgment, which was granted as to the claims of the adult children beneficiaries. The case is scheduled for trial on January 20, 2015.

In December 2013, three new complaints were filed by 34 former members of the McGrogan class:

(1) Jarrett et al. v. First Commonwealth Bank - An action filed by eight plaintiffs on December 2, 2013 in the Westmoreland County Court of Common Pleas asserting claims for fraud in the inducement, fraud in the execution, violation of the UTPCPL, breach of fiduciary duty and promissory estoppel.

(2) Young et al. v. First Commonwealth Bank - An action filed by 12 plaintiffs on December 2, 2013 in the Westmoreland County Court of Common Pleas asserting claims for fraud in the inducement, fraud in the execution, violation of the UTPCPL, breach of fiduciary duty and promissory estoppel.

(3) Fisanik et. al. v. First Commonwealth Bank - An action filed by 14 plaintiffs on December 9, 2013 in the Cambria County Court of Common Pleas asserting claims for fraud in the inducement, fraud in the execution, violation of the UTPCPL, and breach of fiduciary duty.

The 36 plaintiffs who have filed individual actions held Market Rate Savings IRA balances totaling approximately $4 million at the time of the Bank’s resignation as custodian of the IRAs in 2008-09. The average age of the plaintiffs at that time was 62.

The Bank filed preliminary objections to the three new complaints. On July 22, 2014 the court issued an order permitting the three new cases to proceed only on theories of fraud in the execution and violation of the UTPCPL based on fraud in the execution and dismissing the claims for fraud in the inducement, breach of fiduciary duty and promissory estoppel with prejudice. Discovery in the three actions is beginning.

At this time, the Bank believes the claims are without merit.

Other matters

In 2013, First Commonwealth identified an error related to historical tax reporting for approximately 700-900 customers, resulting in the establishment of a $0.8 million contingency reserve. During the second quarter of 2014, a settlement in the amount of $0.4 million was reached with one taxing authority, while resolution with another taxing authority continues. Based on the settlement reached, management's best estimate of the remaining liability for this issue is $0.1 million. As a result, in addition to the settlement amount, $0.3 million of the contingency reserve was reversed during the second quarter of 2014. The contingency reserve is included in “Other liabilities” in the Condensed Consolidated Statements of Financial Condition.

There are no other 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 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.

During the third quarter of 2014, $132.9 million million in available for sale securities were sold as part of a strategy to protect the Company's net interest margin from the effects of a prolonged low interest rate enviroment. Proceeds from the investment sales were reinvested into like securities with a slightly longer duration and higher yield. The overall effect was to increase the yield on the investment portfolio by 7 basis points, while only extending the overall duration of the entire portfolio by 2.4 months.

Securities available for sale with an estimated fair value of $547.1 million and $594.9 million were pledged as of September 30, 2014 and December 31, 2013, respectively, to secure public deposits and for other purposes required or permitted by law.

Note 8 Impairment of Investment Securities

Securities Available for Sale

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 nine months endedSeptember 30, 2014 and 2013, 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 11, “Fair Values of Assets and Liabilities,” for additional information.

As of September 30, 2014, our corporate securities had an amortized cost and an estimated fair value of $6.7 million and $7.3 million, respectively, and were comprised of single issue trust preferred securities issued primarily by large regional banks. As of December 31, 2013, the same portion of the portfolio had an amortized cost of $6.7 million and an estimated fair value of $7.0 million. There were no corporate securities in an unrealized loss position as of September 30, 2014 and December 31, 2013. 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 September 30, 2014, the book value of our pooled trust preferred collateralized debt obligations totaled $42.0 million with an estimated fair value of $29.5 million, which includes securities comprised of 282 banks and other financial institutions. All of our pooled securities are mezzanine tranches, four 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

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 three and nine months endedSeptember 30, 2014 and 2013, 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 September 30, 2014. 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

16

ITEM 1. Financial Statements and Supplementary Data

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 282 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 September 30, 2014, 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 which 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 September 30, 2014, indicates that no credit related other-than-temporary impairment has occurred on our pooled trust preferred securities during the nine months endedSeptember 30, 2014. Based upon the analysis performed by management, it is probable that five 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 September 30, 2014 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 September 30, 2014, 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 22% to 154% 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 are 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 nine months of 2014 and 2013, 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 September 30, 2014 and 2013, there are 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 September 30, 2014 and December 31, 2013, our FHLB stock totaled $51.0 million and $35.4 million, respectively and is included in “Other investments” on the Condensed Consolidated Statements of Financial Condition.

Beginning in July 2013, the FHLB began repurchasing 100% of a member's excess stock on a monthly basis. In the months prior to that in 2013, the FHLB repurchased the lessor of 5% of the members' total capital stock outstanding or its total excess capital stock on a quarterly basis. As a result, during the nine months endedSeptember 30, 2014 and 2013, $16.6 million and $9.9 million, respectively, of the stock owned by First Commonwealth was repurchased. The FHLB repurchased stock and paid dividends in 2014 and 2013, however, decisions regarding any future repurchase of excess capital stock and dividend payments will be made by the FHLB on an ongoing basis.

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. The decision of whether impairment exists is a matter of judgment that reflects our view of the FHLB’s long-term performance, which includes factors such as the following:

• its operating performance;

• the severity and duration of declines in the fair value of its net assets related to its capital stock amount;

• its commitment to make payments required by law or regulation and the level of such payments in relation to its operating performance;

• the impact of legislative and regulatory changes on the FHLB, and accordingly, on the members of FHLB; and

• its liquidity and funding position.

After evaluating all of these considerations, First Commonwealth concluded that the par value of its investment in FHLB stock will be recovered. Accordingly, no impairment charge was recorded on these securities for the nine months endedSeptember 30, 2014. Our evaluation of the factors described above in future periods could result in the recognition of impairment charges on FHLB stock.

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 adversely 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 Bank’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 September 30, 2014. 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.

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 become 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 doubtful.

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

NOTES TO THE UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Continued)

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 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.

Nonperforming loans decreased$14.1 million during the nine months endedSeptember 30, 2014. Contributing to this decrease was the sale of four real estate construction loans totaling $3.0 million and the payoff of six loans totaling $12.5 million. The payoffs included a $4.7 million commercial relationship to a local developer, a $3.1 million commercial real estate loan with a non-profit organization in western Pennsylvania, a $2.9 million commercial real estate loan to a real estate investor in western Pennsylvania, a $0.9 million residential real estate loan in western Pennsylvania, a $0.6 million commercial relationship with a western Pennsylvania glass manufacturer and a $0.3 million commercial real estate loan with a western Pennsylvania real estate investor. Additionally, net charge-offs recognized during the nine-months ended September 30, 2014 totaled $12.1 million including $5.8 million for a commercial industrial loan relationship with a gas drilling business that operated in western Pennsylvania with headquarters in Louisiana and $0.6 million for a commercial loan in western Pennsylvania. The remaining charge-offs were individually for amounts of $0.5 million or less.

Offsetting the previously noted decreases in nonperforming loans is a total of $19.8 million in loans which were moved into nonaccrual status during the nine months endedSeptember 30, 2014, the majority of which relates to a $4.3 million commercial industrial relationship with an audio visual equipment distributor, a $0.7 million commercial real estate relationship with a personal care facility in western Pennsylvania, and a $0.7 million commercial real estate relationship with a western Pennsylvania funeral home. In addition to this, $3.2 million in consumer loans which were 150 days or more past due were moved to nonaccrual status.

The specific allowance for nonperforming loans decreased by $4.2 million at September 30, 2014 compared to December 31, 2013, primarily due to the charge-offs noted on the previously mentioned loans offset by specific reserves recognized on the loans transferred into nonaccrual status. Unfunded commitments related to nonperforming loans were $0.4 million at September 30, 2014 and after consideration of available collateral related to these commitments, a reserve of $14 thousand was established was established for these off balance sheet exposures.

There were $1.3 million loans held for sale at September 30, 2014, all of which were 1-4 family residential loans originated through our recently launched mortgage business. There were no loans held for sale at December 31, 2013. Sales of loans during the nine months endedSeptember 30, 2014 and 2013 resulted in gains of $0.1 million and $0.6 million, respectively.

Significant nonaccrual loans as of September 30, 2014, include the following:

• $10.6 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. One of these loans, totaling $2.7 million, was modified, resulting in TDR classification in the second quarter of 2012. A second of these loans, totaling $0.3 million, was modified, resulting in TDR classification in the first quarter of 2013. During the nine months endedSeptember 30, 2014, chargeoffs of $0.5 million related to this relationship were recorded. A valuation of the collateral was completed during the third quarter of 2013, with updates to significant inputs completed in June 2014.

• $3.9 million in commercial industrial loans to an audio visual equipment distributor. These loans were originated in 2008 and refinanced by the Company in 2013. In the second quarter of 2014, the loans were placed on nonaccrual status. An updated valuation of the collateral was completed during the second quarter of 2014.

• $3.0 million in commercial real estate and industrial loans to a specialty metal processor in western Pennsylvania. These loans were originated in 2003 and were placed on nonaccrual status in the second quarter of 2013. The assets collateralizing this relationship as well as the appraisal for the real estate collateral were valued in the second quarter of 2014.

At September 30, 2014, troubled debt restructured loans decreased$12.5 million compared to December 31, 2013, and commitments related to troubled debt restructured loans increased$0.5 million for the same period. This decrease in loans is primarily a result of the payoff of four commercial loans totaling $11.3 million, including a $4.7 million commercial relationship with a local real estate developer, a $3.1 million commercial real estate loan with a non-profit organization and a $2.9 million commercial real estate loan in western Pennsylvania. The increase in unused line of credit commitments is related to two commercial borrowers.

The change in the unallocated portion of the allowance for credit losses comparing September 30, 2014 with September 30, 2013 is a result of the unallocated portion of the allowance for credit losses no longer being treated as a separate component of the allowance as of December 31, 2013. Instead it is incorporated into the reserve provided for each loan category. This portion of the allowance for credit losses reflects the qualitative or environmental factors that are probable to cause estimated credit losses to differ from historical loss experience.

Note 10 Income Taxes

At September 30, 2014 and December 31, 2013, First Commonwealth had no material unrecognized tax benefits or accrued interest and penalties. If applicable, First Commonwealth will record interest and penalties as a component of noninterest expense. Federal and state tax years 2011 through 2013 were open for examination as of September 30, 2014.

Note 11 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:

28

FIRST COMMONWEALTH FINANCIAL CORPORATION AND SUBSIDIARIES

ITEM 1. Financial Statements and Supplementary Data

NOTES TO THE UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Continued)

• 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, interest rate derivatives that include 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 are comprised of FHLB stock whose estimated fair value is based on its par value. Additional information on FHLB stock is provided in Note 8, “Impairment of Investment Securities.”

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 12, “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 2014, 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 U.S. There has been little or no active trading in these securities since 2009; therefore

29

FIRST COMMONWEALTH FINANCIAL CORPORATION AND SUBSIDIARIES

ITEM 1. Financial Statements and Supplementary Data

NOTES TO THE UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Continued)

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 8, “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	$29,456	Discounted Cash Flow	Probability of default	0% - 100% (18.02%)
			Prepayment rates	0% - 100% (6.61%)
			Discount rates	5.25% - 14.00% (a)
Equities	1,420	Par Value	N/A	N/A
Interest Rate Swap	—	Option model	Counterparty credit risk	3.69% - 6.82% (b)

			Gas per MCF	$3.84 - $6.45 (d)
			Oil per BBL/d	$83.64 - $107.00 (d)
			NGL per gallon	$0.83 (d)
	113 (c)	Discounted Cash Flow	Discount Rate	9.00%
Other Real Estate Owned	190	Internal Valuation	N/A	N/A

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

(b) represents the range of the credit spread curve used in valuation.

(c) 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.

(d) 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 higher fair value measurement. Other unobservable inputs in the fair value measurement of impaired loans relate to gas, oil and natural gas prices and increases in these rates 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.

The significant unobservable input used in the fair value measurement of interest rate swaps classified as Level 3 is counterparty credit risk and the resulting range of the credit spread curve used in the valuation. Higher credit risk would result in an increased credit spread, which would reduce the fair value of the interest rate swap.

For the nine months endedSeptember 30, 2014 and 2013, there were no transfers between fair value Levels 1 and 2. However, $3.0 million and $20.1 million of loans were transferred into Level 3 from Level 2 during the nine months endedSeptember 30, 2014 and 2013, respectively, 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 September 30, 2014 and 2013.

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

For the three months endedSeptember 30, 2014 and 2013, there were no transfers between fair value Levels 1 and 2. Additional proceeds from a loan sale in the second quarter of 2013 resulted in a $0.2 million gain for the three months ended September 30, 2013. There were no gains or losses included in earnings for periods presented that are attributable to the change in realized gains(losses) relating to assets held at September 30, 2014 and 2013.

Total losses	$	405		$	(1,558	)	$	(2,400	)	$	(13,251	)

Impaired loans over $0.1 million 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 $7.8 million as of September 30, 2014 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 13, “Goodwill.” There were no other assets or liabilities measured at fair value on a non-recurring basis during the nine months endedSeptember 30, 2014.

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 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.”

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 $0.1 million at September 30, 2014 and December 31, 2013, respectively. See Note 6, “Commitments and Contingent Liabilities,” for additional information.

Deposit liabilities: 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.

NOTES TO THE UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Continued)

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 12 Derivatives

Derivatives Not Designated as Hedging Instruments

First Commonwealth is a party to interest rate derivatives that are not designated as accounting hedges. These derivatives relate to interest rate swaps that First Commonwealth entered 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.

ITEM 1. Financial Statements and Supplementary Data

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 thirteen 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 four 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 providing 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

During the third quarter of 2014, the Company entered into two interest rate swap contracts which were designated as cash flow hedges. Both of the interest rate swaps have a notional amount of $50.0 million with a maturity of three years on one and four years on the other. 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 $100.0 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 Statement of Income. For the three and nine months ended September 30, 2014, there was no 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 Statement of Income as the income on the hedged items. The cash flow hedges were highly effective at September 30, 2014, and changes in the fair value attributed to hedge ineffectiveness were not material. There were no cash flow hedges at December 31, 2013.

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 13 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 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.

First Commonwealth is considered to be one reporting unit. The carrying amount of goodwill as of September 30, 2014 and December 31, 2013 was $159.4 million and $159.9 million, respectively. No impairment charges on goodwill or other intangible assets were incurred in 2014 or 2013. The $0.5 million decline in goodwill during the nine months ended September 30, 2014 represents the amount of goodwill included in the carrying value of the investment advisory business which was sold during the first quarter of 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. An assessment of qualitative factors was completed as of September 30, 2014 and indicated that it is more likely than not that the fair value of First Commonwealth exceeds its carrying amount, therefore the two step goodwill impairment test was not considered necessary. The assessment of qualitative factors incorporated the results of the Step 1 goodwill impairment test completed as of November 30, 2013 as well as macroeconomic factors, industry and market considerations, the company’s overall financial performance, and other company specific events occurring since the completion of the November 30, 2013 test.

As of September 30, 2014, goodwill was not considered impaired; however, changing economic conditions that may adversely affect our performance, fair value of our assets and liabilities, or 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 14 Subsequent Events

On October 1, 2014, the Company acquired Thompson/McLay Insurance Associates an Indiana, PA based insurance agency. The addition of Thompson/McLay provides access to approximately twelve new insurance carriers, allowing for greater scale and product offerings. Thompson/McLay will initially retain its name and operate as a division of First Commonwealth Insurance Agency.

Note 15 New Accounting Pronouncements

In January 2014, the FASB issued ASU 2014-01, "Investments - Equity Method and Joint Ventures (Topic 323)," which permits reporting entities to make an accounting policy election to account for their investments in qualified affordable housing projects using the proportional amortization method if certain conditions are met. The proportional amortization method allows an entity to amortize the initial cost of the investment in proportion to the tax credits and other tax benefits received and recognizes the net investment performance in the income statement as a component of income tax expense (benefit). This amendment is effective for interim and annual periods beginning after December 15, 2014. The adoption of this ASU is not expected to have a material impact on First Commonwealth’s financial condition or results of operations.

In January 2014, the FASB issued ASU 2014-04, "Receivables - Troubled Debt Restructurings by Creditors (Subtopic 310-40)." This amendment clarifies that an in-substance repossession or foreclosure occurs and a creditor is considered to have received physical possession of property upon either, 1. the creditor obtaining legal title to the residential real estate property upon completion of a foreclosure, or 2. the borrower conveying all interest in the residential real estate property to the creditor to satisfy that loan through completion of a deed in lieu of foreclosure or through a similar legal agreement. Interim and annual disclosure of both the amount of foreclosed residential real estate property held by the creditor and the recorded investment in consumer mortgage loans collateralized by residential real estate property that are in the process of foreclosure according to local requirements of the applicable jurisdiction are required. This amendment is effective for annual periods beginning after December 15, 2014 and for interim periods within annual periods 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.

In April 2014, the FASB issued ASU 2014-08, “Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360)." This amendment changes the reporting requirements for discontinued operations. A disposal of a component of an entity or group of components of an entity is required to be reported in discontinued operations if the disposal represents a strategic shift resulting in a major effect on the entity's operations and financial results when any of the following occurs: 1. the component or group of components of an entity meets the criteria to be classified as held for sale, 2. the component or group of components of an entity is disposed of by sale, or 3. the component or group of components of an entity is disposed of other than by sale. If one of these criteria are met, the entity will present the assets and liabilities of a disposal group that includes a discontinued operation separately in the asset and liability sections of the statement of financial position for each comparative period along with additional footnote disclosure. This amendment is effective for annual periods beginning on or after December 15, 2014 and interim periods within annual periods beginning on or 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.

In May 2014, the FASB issued Update No. 2014-09, "Revenue from Contracts with Customers (Topic 606)." The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve that core principle, an entity should: 1) identify the contract(s) with a customer, 2) identify the performance obligations in the contract, 3) determine the transaction price, 4) allocate the transaction price to the performance obligations in the contract, and 5) recognize revenue when (or as) the entity satisfies a performance obligation. This update is effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period, and early adoption is not permitted. The adoption of this ASU is not expected to have a material impact on First Commonwealth’s financial condition or results of operations.

In June 2014, the FASB issued ASU 2014-11, "Transfers and Servicing (Topic 860)," which requires two accounting changes. One changes the accounting for repurchase-to-maturity transactions to secured borrowing accounting and the other requires separate accounting for a transfer of a financial asset executed contemporaneously with a repurchase agreement with the same counterparty in regards to repurchase financing arrangements, which will result in secured borrowing accounting for the repurchase agreement. The Update requires disclosure for certain transactions comprising a transfer of a financial asset accounted for as a sale and an agreement with the same transferee entered into in contemplation of the initial transfer that results in the transferor retaining substantially all of the exposure to economic return. The amendment also requires disclosure for repurchase agreements, securities lending transactions, and repurchase-to-maturity transactions that are accounted for as secured borrowings. This amendment will be effective for public entities for the first interim or annual period beginning after December 15, 2014. The adoption of this ASU is not expected to have a material impact on First Commonwealth’s financial condition or results of operations.

NOTES TO THE UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Continued)

In June 2014, the FASB issued ASU 2014-12, "Compensation - Stock Compensation (Topic 718)," which requires that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. As such, the performance target should not be reflected in estimating the grant-date fair value of the award. Compensation cost should be recognized in the period in which it becomes probable that the performance target will be achieved and should represent the compensation cost attributable to the period(s) for which the requisite service has already been rendered. If the performance target becomes probable of being achieved before the end of the requisite service period, the remaining unrecognized compensation cost should be recognized prospectively over the remaining requisite service period. This amendment is effective for annual periods and interim periods within those annual periods beginning after December 15, 2015 with earlier adoption permitted. The adoption of this ASU is not expected to have a material impact on First Commonwealth’s financial condition or results of operations.

In August 2014, the FASB issued ASU No. 2014-14. "Receivables – Troubled Debt Restructurings by Creditors (Subtopic 310-40): Classification of Certain Government-Guaranteed Mortgage Loans upon Foreclosure." These amendments address the diversity in practice regarding the classification and measurement of foreclosed loans which were part of a government-sponsored loan guarantee program (e.g. HUD, FHA, VA). The ASU outlines certain criteria that, if met, the loan (residential or commercial) should be derecognized and a separate other receivable should be recorded upon foreclosure at the amount of the loan balance (principal and interest) expected to be recovered from the guarantor. This ASU will be effective for annual reporting periods beginning after December 15, 2014, including interim periods within that reporting period. Early adoption is permitted, provided the entity has adopted ASU 2014-04. The ASU should be adopted either prospectively or on a modified retrospective basis. The adoption of this ASU is not expected to have a material impact on First Commonwealth’s financial condition or results of operations.

In August 2014, the FASB issued ASU 2014-15, "Presentation of Financial Statements - Going Concern (Topic 205-40)," which requires management to evaluate, for each annual and interim period, whether conditions or events, considered in the aggregate, raise substantial doubt about the entity's ability to continue as a going concern within one year after the date that the financial statements are issued. When management identifies conditions or events that raise substantial doubt regarding an entity's ability to continue as a going concern, management should consider whether its plans that are intended to mitigate those relevant conditions or events will alleviate the substantial doubt. Certain footnote disclosures are required, the nature of which depends on if substantial doubt is alleviated as a result of consideration of management's plan. This amendment is effective for the annual period ending after December 15, 2016 and for annual and interim periods thereafter. The adoption of this ASU is not expected to have a material impact on First Commonwealth’s financial condition or results of operations.

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. 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. The following list, which is not intended to be an all-encompassing list of risks and uncertainties affecting us, summarizes several factors that could cause our actual results to differ materially from those anticipated or expected in these forward-looking statements:

• weakening economic and business conditions, both nationally and in our markets, which could cause deterioration in credit quality, a further reduction in demand for credit and/or a further decline in real estate values;

• prolonged low interest rates, which could reduce our net interest margin;

• increases in defaults by borrowers and other delinquencies, which could result in increases in our provision for credit losses and related expenses;

• cyber-attacks and fraud, which could disrupt our systems and services, breach the privacy of our customer and business information or result in loss of client assets;

• legislative and regulatory changes, including the impact of the Dodd-Frank Wall Street Reform and Consumer Protection Act, the Consumer Financial Protection Bureau, the capital ratios of Basel III as adopted by federal banking authorities and related regulations, subject us to additional regulatory oversight which may result in increased compliance costs and/or require us to change our business model;

• declines in the valuations of real estate, which could negatively affect the creditworthiness of our borrowers and the value of collateral securing our loans;

• the assumptions used in calculating the appropriate amount to be placed into our allowance for credit losses may prove to be inaccurate;

• restrictions or conditions imposed by our regulators on our operations may make it more difficult for us to achieve our goals;

• further declines in the market value of investment securities that are considered to be other-than-temporary, which would negatively impact our earnings and capital levels;

• changes in accounting standards and compliance requirements may have an adverse affect on our operating results and financial condition;

• competitive pressures among depository and other financial institutions, some of which may have greater financial resources or more attractive product or service offerings, may adversely affect growth or profitability of our products and services; and

• 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.

ITEM 2. Management’s Discussion and Analysis of Financial Condition and

Results of Operations (Continued)

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 page 43 and 50 for the three and nine months endedSeptember 30, 2014 and 2013.

Results of Operations

Nine Months EndedSeptember 30, 2014 Compared to Nine Months EndedSeptember 30, 2013

Net Income

For the nine months endedSeptember 30, 2014, First Commonwealth had net income of $36.7 million, or $0.39 per share, compared to net income of $32.2 million, or $0.33 per share, in the nine months endedSeptember 30, 2013. The increase in net income was primarily the result of a reduction in the provision for credit losses, offset by declines in net interest income. Noninterest expense remained relatively flat, despite $7.3 million in IT conversion related expenses recognized during the nine months ended September 30, 2014.

Net Interest Income

Net interest income, on a fully taxable equivalent basis, was $140.0 million in the first nine months of 2014, compared to $141.4 million for the same period in 2013. This decrease was primarily the result of $1.0 million in income recognized on other-than-temporarily impaired pooled trust preferred collateralized debt obligations that received non-recurring payments during the third quarter of 2013. These payments added two basis points to the net interest margin for the nine month period ending September 30, 2013. Net interest income comprises a majority of our operating revenue (net interest income before provision expense plus noninterest income) at 75% for both the nine months endedSeptember 30, 2014 and 2013.

The net interest margin, on a fully taxable equivalent basis, was 3.28% for the nine months endedSeptember 30, 2014 compared to 3.41% for the nine months endedSeptember 30, 2013. The 13 basis point decline can be attributed to the previously mentioned income on pooled trust preferred securities, rate decreases resulting from the repricing of our adjustable rate assets, lower replacement yields for the repayment or amortization of fixed rate assets as well as lower interest rates available on new investments and loans.

The taxable equivalent yield on interest-earning assets was 3.62% for the nine months endedSeptember 30, 2014, a decrease of 19 basis points from the 3.81% yield for the same period in 2013. Growth in earning assets has helped to offset the spread compression, as average earning assets for the nine months endedSeptember 30, 2014 increased $155.0 million, or 3%, compared to the comparable period in 2013. However, approximately 45% of the growth in earning assets for the period was generated by the investment portfolio, where purchases provide approximately 118 basis points less yield than the loan portfolio. Investment portfolio purchases during the nine months endedSeptember 30, 2014 have been primarily in mortgage-related assets with approximate durations of 36-48 months and municipal securities with a duration of 10 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 partially offset the impact of lower yields on interest-earning assets. The cost of interest-bearing liabilities was 0.42% for the nine months endedSeptember 30, 2014, compared to 0.50% for the same period in 2013.

For the nine months endedSeptember 30, 2014 , changes in interest rates negatively impacted net interest income by $6.5 million when compared with the same period in 2013. The lower yield on interest-earning assets adversely impacted net interest income by $8.1 million, while the decline in the cost of interest-bearing liabilities had a positive impact of $1.6 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 tempered the effect on net interest income. Changes in the volumes of interest-earning assets and interest-bearing liabilities positively impacted net interest income by $5.1 million in the nine months endedSeptember 30, 2014, as compared to the same period in 2013. Higher levels of interest-earning assets resulted in an increase of $4.2 million in interest income, while volume changes decreased interest expense by $0.8 million, primarily as the result of changes in long-term debt and time deposits, including brokered deposits.

Net interest income also benefited from a $91.9 million increase in average net free funds at September 30, 2014 as compared to September 30, 2013. 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 $84.4 million, or 9.7%, in noninterest-bearing demand deposit average balances as a result of marketing promotions aimed at attracting new and retaining existing ones. Additionally, higher cost time deposits continue to mature and reprice to lower cost customers certificates of deposit or other deposit alternatives. Average time deposits for the nine months endedSeptember 30, 2014 decreased by $102.1 million compared to the comparable period in 2013.

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 or 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 nine months endedSeptember 30:

	2014					2013
	Dollars			Percentage		Dollars			Percentage
	(dollars in thousands)
Commercial, financial, agricultural and other	$	4,773		55	%	$	12,038		67	%
Real estate construction	1,331			16		(1,865		)	(10	)
Residential real estate	(407		)	(5	)	446			2
Commercial real estate	1,453			17		4,318			24
Loans to individuals	1,471			17		2,266			13
Unallocated	—			—		808			4
Total	$	8,621		100	%	$	18,011		100	%

The provision for credit losses for the nine months endedSeptember 30, 2014decreased in comparison to the nine months endedSeptember 30, 2013 by $9.4 million, or 52%, as a result of overall improvement in loan portfolio credit metrics. The majority of the 2014 provision expense, or $5.8 million, is attributable to specific reserves for an $8.2 million loan to an oil and gas servicing company, which was transferred to nonaccrual status during the first quarter of 2014. This loan was sold during the second quarter of 2014, resulting in a $5.8 million charge-off. Also impacting the provision expense for the commercial, financial, and agricultural loan category were specific reserves related to a $3.9 million loan to an audio visual equipment distributor, which was transferred into nonaccrual status during the second quarter of 2014. Offsetting these increases in provision expense was the release of approximately $2.7 million in specific reserves related to the payoff of a $4.7 million

nonaccrual loan to a local developer. For the nine months ended September 30, 2014, the negative provision expense for residential real estate is a result of declines in both the level of impaired loans and historical loss rates for this loan category. Provision expense for real estate construction and real estate commercial loan were impacted by an increase in historical loss percentages and qualitative factors including vacancy, capitalization and absorption rates. Provision expense for loans to individuals is directly related to the level of charge-offs for the nine-month period. The level of provision expense for the nine months ended September 30, 2013 was primarily due to further deterioration in the value of certain assets of a commercial relationship with a local developer, which resulted in a net charge-off of $10.1 million, as well as the sale of two commercial real estate loans sold in the first quarter of 2013 that resulted in an additional $3.1 million in provision expense.

The allowance for credit losses was $50.8 million, or 1.15%, of total loans outstanding at September 30, 2014, compared to $54.2 million, or 1.27%, at December 31, 2013 and $55.0 million, or 1.30%, at September 30, 2013. The change compared to December 31, 2013, can be attributed to a $22.9 million, or 14%, decrease in criticized loans, which includes a reduction of $14.1 million, or 24%, in nonperforming loans as well as a $4.2 million decrease in the level of specific reserves held on impaired loans. Nonperforming loans as a percentage of total loans decreased to 1.03% at September 30, 2014 from 1.39% at December 31, 2013 and 1.68% as of September 30, 2013. The allowance to nonperforming loan ratio was 112.21%, 91.31% and 77.17% as of September 30, 2014, December 31, 2013 and September 30, 2013, respectively.

Below is an analysis of the consolidated allowance for credit losses for the nine months endedSeptember 30, 2014 and 2013 and the year-ended December 31, 2013:

Total noninterest income	$	46,972	$	46,899	$	73		—	%

Noninterest income, excluding net securities gains and gain on sale of assets, decreased$2.2 million, or 5%, for the first nine months of 2014 compared to 2013. The most notable change is a $3.1 milliondecrease in the other income category, which is largely attributable to a $1.6 million reduction in commercial loan swap-related income as well as a $0.2 million decrease in letter of credit fees. The decline in swap-related income is primarily due to a $1.0 million decline in counterparty credit risk.

Total noninterest income for the nine months ended September 30, 2014 was basically unchanged in comparison to the nine months endedSeptember 30, 2013. The most significant change includes a $2.4 millionincrease in gain on sale of assets as a result of a $1.2 million gain recognized on the sale of the Company's registered investment advisory business and $3.1 million in gains on the sale of several OREO properties.

During the third quarter of 2014, the Company acquired Thompson/McLay Insurance Associates an Indiana, PA based insurance agency. Although this transaction will provide additional non-interest income, in the near term it is expected to be minimally accretive to earnings.

Noninterest expense, excluding loss on redemption of subordinated debt and conversion related expenses, decreased$5.2 million, or 4%, for the nine months endedSeptember 30, 2014 compared to the same period in 2013. Contributing to the 2014 decrease is a $1.4 million decline in Pennsylvania shares tax as a result of changes in the Pennsylvania tax law and a $0.9 million decrease in collection and repossession expense due to the resolution of several large credits. Additionally, there was a $2.7 million decline in other operating expense, in part due to a $0.9 million insurance recovery received in the first quarter of 2014 related to a $3.5 million fraud loss recognized in 2012. Also contributing to the decline in other operating expenses was $0.8 million in expense recognized during the nine months ended September 30, 2013 related to a contingency reserve for a 1099 tax reporting issue. During the nine months ended September 30, 2014, an agreement was reached with one taxing authority resulting in the reversal of $0.3 million of the reserve from expense.

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. As a result of this conversion, First Commonwealth incurred $11.8 million of charges, of which $7.3 million was recognized during the nine months ended September 30, 2014. These expenses include accelerated depreciation for data processing hardware and software, early termination charges on previous contracts, and staffing and employment-related charges. During the nine months endedSeptember 30, 2014, $5.6 million in accelerated depreciation and $1.7 million in other conversion related expenses were recognized. The system conversion is expected to provide expense savings from pre-conversion levels of approximately $1.5 million to $1.7 million per quarter, the full effect of which is expected to be recognized starting in the fourth quarter of 2014.

On April 1, 2013, $32.5 million in redeemable capital securities issued by First Commonwealth Capital Trust I were redeemed, resulting in a loss of $1.6 million. This loss includes a $1.1 million prepayment penalty and $0.5 million of unamortized deferred issuance costs. There were no similar expenses in 2014.

Income Tax

The provision for income taxes increased$3.8 million for the nine months endedSeptember 30, 2014, compared to the corresponding period in 2013. The higher provision for income taxes was primarily the result of an $8.3 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 nine months endedSeptember 30, 2014 and 2013.

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 29.4% and 26.3% for the nine months endedSeptember 30, 2014 and 2013, respectively.

As of September 30, 2014, our deferred tax assets totaled $51.1 million. Based on our evaluation as of September 30, 2014, we determined that it is more likely than not that all of these assets will be realized. As a result, we did not record a valuation allowance against these assets. 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 EndedSeptember 30, 2014 Compared to Three Months EndedSeptember 30, 2013

Net Income

For the three months endedSeptember 30, 2014, First Commonwealth had net income of $12.5 million, or $0.13 per share, compared to net income of $15.9 million, or $0.16 per share, in the three months endedSeptember 30, 2013. The decrease in net income was driven by a decrease in noninterest income and increased noninterest expense.

Net Interest Income

Net interest income, on a fully taxable equivalent basis, was $47.4 million in the third quarter of 2014 compared to $48.3 million for the same period in 2013. Net interest income comprises a majority of our operating revenue (net interest income before provision expense plus noninterest income), at 76% and 73% for the three months endedSeptember 30, 2014 and 2013, respectively.

The net interest margin, on a fully taxable equivalent basis, was 3.26% for the three months endedSeptember 30, 2014, compared to 3.43% for the three months endedSeptember 30, 2013. The 17 basis point decline was the result of by both changes in the level of interest rates and the amount and composition of interest-earning assets and interest-bearing liabilities.

Runoff of existing assets earning higher interest rates and competitive pricing pressure has continued to provide for lower yields on earning assets. Growth in earning assets has helped to offset the spread compression, as average earning assets for the three months endedSeptember 30, 2014 increased $185.7 million, or 3%, compared to the comparable period in 2013. However, during the third quarter of 2014, approximately 30% of the growth in earning assets, was generated by the investment portfolio, where purchases provide approximately 129 basis points less yield than the loan portfolio. Investment portfolio purchases during the three months endedSeptember 30, 2014 have been primarily in mortgage-related assets with approximate durations of 36-48 months and municipal securities with a duration of 10 years. The mortgage-related investments have monthly principal payments that will provide for reinvestment opportunities as interest rates rise.

The taxable equivalent yield on interest-earning assets was 3.57% for the three months endedSeptember 30, 2014, a decrease of 22 basis points from the 3.79% yield for the same period in 2013. This decline can be attributed to the repricing of our adjustable rate assets and the repayment or amortization of fixed rate assets in a declining interest rate environment, as well as lower interest rates available on new investments and loans. Reductions in the cost of interest-bearing liabilities partially offset the impact of lower yields on interest-earning assets. The cost of interest-bearing liabilities was 0.39% for the three months endedSeptember 30, 2014, compared to 0.45% for the same period in 2013.

Comparing the three months endedSeptember 30, 2014 with the same period in 2013, changes in interest rates negatively impacted net interest income by $3.2 million. The lower yield on interest-earning assets adversely impacted net interest income by $3.3 million, while the decline in the cost of interest-bearing liabilities had a positive impact of $0.2 million.

While decreases in interest rates and yields compressed the net interest margin, increases in average interest-earning assets tempered the effect on net interest income. Changes in the volumes of interest-earning assets and interest-bearing liabilities positively impacted net interest income by $2.3 million in the three months endedSeptember 30, 2014, as compared to the same period in 2013. Higher levels of interest-earning assets resulted in an increase of $1.9 million in interest income, while volume changes decreased interest expense by $0.4 million, primarily as the result of runoff in time deposits.

Positively affecting net interest income was a $142.6 million increase in average net free funds at September 30, 2014, as compared to September 30, 2013. 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 in noninterest-bearing demand deposit average balances. Additionally, higher costing time deposits continue to mature and reprice to lower costing certificates or other deposit alternatives. Average time deposits for the three months endedSeptember 30, 2014 decreased $190.3 million compared to the comparable period in 2013.

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 or 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 endedSeptember 30, 2013 and 2014:

	2014					2013
	Dollars			Percentage		Dollars			Percentage

Unallocated	—			—		812			30
Total	$	2,073		100	%	$	2,714		100	%

The provision for credit losses for the three months endedSeptember 30, 2014decreased in comparison to comparable period in 2013 by $0.6 million, or 23.6%. For the three months ended September 30, 2014, the negative provision expense for the commercial, financial and agricultural loans is primarily due to a decline in historical loss rates, while the negative provision for residential real estate loans is a result of declines in both historical loss rates and qualitative factors, such as national delinquency and consumer sentiment. The level of provision expense for real estate construction loans and commercial real estate loans can be attributed to loan growth in these categories, as well as an increase in qualitative factors such as vacancy,

capitalization rates and absorption. During the third quarter of 2013, the negative provision expense for real estate construction loans can be attributed to a decline in the historical loss percentage used to determine the appropriate level of allowance for credit losses.

by $1.3 million as a result of a $0.5 million decrease in interest rate swap related income, a $0.4 million decline in income generated from the management advisory business sold in the first quarter of 2014, and a $0.1 million decrease in letter of credit fees.

Conversion related expenses	783		65		718			1,105	%
Total noninterest expense	$	41,568	$	40,045	$	1,523		4	%

Noninterest expense, excluding conversion related expenses, decreased$0.6 million, or 2%, for the three months endedSeptember 30, 2014, as compared to the same period in 2013. The primary reason for this decline was a lower level of other operating expense in the three months ended September 30, 2014, due to a $0.6 million decline in the reserve for unfunded commitments and a $0.4 million decrease in loss on sale or writedown of OREO properties. Additionally, changes in the Pennsylvania tax law provided for a $0.5 million decline in the Pennsylvania shares tax expense.

Partially offseting the decline in other operating expense was a $1.2 million increase in salary and employee benefit expense. Contributing to this increase were higher incentive payments of $0.8 million as a result of successful sales efforts and increased loan volumes. Additionally, an increase of $0.4 million in overtime expense was recognized as a result of the additional hours related to the system conversion completed in the third quarter of 2014.

As previously noted, in 2013 First Commonwealth executed a contract with Jack Henry and Associates to license the Jack Henry and Associates SilverLake System core processing software and to outsource certain data processing services. A system conversion was completed in the third quarter of 2014 and resulted in a total of $11.8 million of conversion related charges over the four quarter period ending September 30, 2014. During the three months endedSeptember 30, 2014, $1.4 million in accelerated depreciation and $0.8 million in other conversion-related expenses were recognized.

Income Tax

The provision for income taxes decreased$0.2 million for the three months endedSeptember 30, 2014, compared to the corresponding period in 2013. The lower provision for income taxes was primarily the result of a $3.6 milliondecrease in the level of income before taxes.

ITEM 2. Management’s Discussion and Analysis of Financial Condition and

Results of Operations (Continued)

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 endedSeptember 30, 2014 and 2013.

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 30.4% and 26.4% for the three months endedSeptember 30, 2014 and 2013, 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 nine months of 2014, liquidity provided from the net increase in short-term borrowings totaled $408.4 million, while the maturity and redemption of investment securities provided $199.6 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 (“FRB”) of Cleveland 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 September 30, 2014, our maximum borrowing capacity under this program was $950.7 million and as of that date there was $194.6 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 September 30, 2014, our outstanding certificates of deposits from this program have an average weighted rate of 0.26% and an average original term of 65 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 September 30, 2014, the borrowing capacity under this program totaled $702.4 million and there were no amounts outstanding.

As of September 30, 2014, our maximum borrowing capacity at the FHLB of Pittsburgh was $1.6 billion and as of that date amounts used against this capacity included $988.6 million in outstanding borrowings and $28.2 million in letter of credit commitments used for pledging public funds and other non-deposit purposes.

First Commonwealth Financial Corporation has an unsecured $15.0 million line of credit with another financial institution. As of September 30, 2014, 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:

	September 30, 2014		December 31, 2013
	(dollars in thousands)
Noninterest-bearing demand deposits	$	995,014	$	912,361
Interest-bearing demand deposits	82,221		89,149
Savings deposits	2,363,464		2,506,631
Time deposits	931,689		1,095,722
Total	$	4,372,388	$	4,603,863

During the first nine months of 2014, total deposits decreased$231.5 million due to a $164.0 milliondecrease in time deposits and a decrease of $150.1 million in interest-bearing and savings deposits, offset by a $82.7 million increase in noninterest-

bearing deposits. The decrease in time deposits is due to a decline in wholesale certificates of deposits of $56.5 million coupled with a decline in core certificates of deposit of $107.5 million. Wholesale certificates can offer a more attractive source of incremental funding as they generally have a lower incremental cost of funds than traditional certificates of deposit funding. The decline in interest-bearing demand and savings deposits are partially due to the elimination in 2014 of several promotional interest rates as a means of standardizing rates in anticipation of the IT system conversion described earlier.

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 0.71 at September 30, 2014 and December 31, 2013, 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 September 30, 2014 and December 31, 2013:

The following table presents an analysis of the potential sensitivity of our annual net interest income to gradual changes in interest rates over a 12 month time frame as compared with net interest income if rates remained unchanged and there are no changes in balance sheet categories.

	Net interest income change (12 months)
	-200			-100			+100			+200
	(dollars in thousands)
September 30, 2014	$	(6,407	)	$	(2,662	)	$	(503	)	$	(67	)
December 31, 2013	(8,878		)	(4,355		)	(833		)	(646		)

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 nine months endedSeptember 30, 2014 and 2013, the cost of our interest-bearing liabilities averaged 0.42% and 0.50%, respectively, and the yield on our average interest-earning assets, on a fully taxable equivalent basis, averaged 3.62% and 3.81%, 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 than previously modeled and the repricing sensitivity was determined to 26 basis points less in a 100 basis point increase in interest rates.

The above mentioned nonmaturity deposit analysis, which helped the Company better understand the duration of its liabilities, provided management with the opportunity to employ alternative ALCO strategies to help protect the net interest margin. As a result, during the third quarter of 2014 the Company implemented two ALCO strategies; a bond exchange transaction and a cash flow interest rate hedge. The bond exchange transaction involved the sale of $132.8 million in securities and the purchase of a like amount of similar securities with slightly longer durations. The overall effect of this transaction was to increase the yield on the investment portfolio by 7 basis points, while extending the overall duration of the entire investment portfolio by 2.4 months. The second transaction was a cash flow interest rate swap, in which we extended the duration of $100.0 million of the $1.3 billion LIBOR based loans in our loan portfolio. If short-term interest rates remain low, the effect of these two strategies is expected to add approximately $1.8 million of pre-tax income on an annualized basis in the first year. These strategies add two to three basis points of protection to the net interest margin as a hedge against a prolonged low-rate environment, while still maintaining the overall asset-sensitive position of the bank to take advantage of rising rates when they eventually do occur.

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, delinquency 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 $2.9 million at September 30, 2014 and is classified in "Other liabilities" on the Condensed Consolidated Statements of Financial Condition.

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 nine months of 2014, 60 loans totaling $3.9 million were identified as troubled debt restructurings. Please refer to Note 9, “Loans and Allowance for Credit Losses,” for additional information on troubled debt restructurings.

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 specifically assigned allowance for loan losses are recognized where appropriate.

There was continued improvement in the majority of the Company's credit metrics during the third quarter of 2014. The allowance for credit losses was $50.8 million at September 30, 2014 or 1.15% of total loans outstanding compared to 1.27% reported at December 31, 2013 and 1.30% at September 30, 2013. General reserves as a percentage of non-impaired loans were 1.06% at September 30, 2014 compared to 1.07% at December 31, 2013 and 1.12% at September 30, 2013. Nonperforming loan balances decreased $14.1 million during the first nine months of 2014. Criticized loans totaled $139.4 million at September 30, 2014 and represented 3% of the loan portfolio. The level of criticized loans decreased as of September 30, 2014 when compared to December 31, 2013, by $22.9 million, or 14%. Delinquency on accruing loans for the same period increased$5.1 million, or 39%, the majority of which are commercial real estate and residential real estate loans.

The allowance for credit losses as a percentage of nonperforming loans was 112.21% as of September 30, 2014 compared to 91.31% at December 31, 2013 and 77.17% at September 30, 2013. The amount of allowance related to 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 allocations of $4.6 million and general reserves of $46.2 million. Management believes that the allowance for credit losses is at a level deemed sufficient to absorb losses inherent in the loan portfolio at September 30, 2014.

Nonperforming loans decreased$14.1 million to $45.3 million at September 30, 2014 compared to $59.4 million at December 31, 2013. This decrease can be primarily attributed to the payoff of five nonperforming loan relationships totaling $11.6 million and the sale of three nonperforming loans totaling $0.7 million. Offsetting these decreases was the addition of a $3.9 million commercial industrial loan to an audio visual equipment distributor.

The following tables show the outstanding balances of our loan portfolio and the breakdown of net charge-offs and nonperforming loans by loan type as of and for the periods presented:

	September 30, 2014				December 31, 2013

During the nine months endedSeptember 30, 2014, loans increased$127.6 million or 3% compared to balances outstanding at December 31, 2013. Loan growth was experienced in all categories, except residential real estate. Impacting commercial financial and agricultural loans as well as commercial real estate loans was the opening in early 2014 of a new commercial business center in Cleveland as well as growth in direct middle market lending and syndications in Pennsylvania and contiguous states. Loans to Individuals increased due to growth in indirect auto lending.

The decline in the residential real estate category can be attributed to continued runoff in our mortgage portfolio, since the Company has not offered a traditional mortgage product in close to ten years. During the third quarter of 2014, the Company launched its mortgage banking division, which will provide purchase and refinance mortgage products across our western Pennsylvania footprint. Many of the mortgage loans originated through this division will be sold in the secondary market; therefore, it is likely that non-interest income will be impacted more than the loan portfolio.

Net charge-offs for the nine months endedSeptember 30, 2014 totaled $12.1 million compared to $30.2 million for the nine months endedSeptember 30, 2013. The most significant charge-offs during the nine months endedSeptember 30, 2014 were $8.0 million recognized on two commercial loans and sixteen consumer loan relationships. During the nine months endedSeptember 30, 2013, the most significant charge-offs were a $21.2 million charge recognized on four commercial real estate loans and a $3.1 million charge-off recognized upon transfer of two loans to held for sale.

Capital Resources

At September 30, 2014, shareholders’ equity was $709.5 million, a decrease of $2.2 million from December 31, 2013. The decrease was primarily the result of $36.7 million in net income and increases of $10.9 million in the fair value of available for sale investments, offset by $30.9 million of common stock repurchases and $19.8 million of dividends paid to shareholders. Cash dividends declared per common share were $0.21 and $0.17 for the nine months endedSeptember 30, 2014 and 2013, respectively.

First Commonwealth is 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 its banking subsidiary 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 2013.

On July 9, 2013, federal banking agencies approved changes to the regulatory capital framework which are effective beginning on January 1, 2015, with some items phasing in over a period of time. The most significant of these 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

60

ITEM 2. Management’s Discussion and Analysis of Financial Condition and

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. Management currently expects First Commonwealth will remain well-capitalized after the adoption of these changes.

Under current regulations, quantitative measures to ensure capital adequacy require First Commonwealth to maintain minimum amounts and ratios of Total and Tier I capital (common and certain other “core” equity capital) to risk weighted assets, and of Tier I capital to average assets. As of September 30, 2014, First Commonwealth and its banking subsidiary met all capital adequacy requirements to which they are subject.

As of September 30, 2014, First Commonwealth was considered well-capitalized under the regulatory framework for prompt corrective action. To be considered well capitalized, the Company must maintain minimum Total risk-based capital, Tier I risk-based capital and Tier I leverage ratios as set forth in the table below:

	Actual				Regulatory Minumum				Well Capitalized Regulatory

During the first quarter of 2014, First Commonwealth completed share repurchase programs in the amount of $25.0 million and $50.0 million which were previously announced on January 29, 2013 and June 19, 2012, respectively. On February 19, 2014, First Commonwealth's Board of Directors authorized an additional $25.0 million common stock repurchase program. As of September 30, 2014, First Commonwealth had completed this program by purchasing 2,924,066 shares at an average price of $8.58 per share. Under all three share repurchase programs, First Commonwealth purchased a total of 13,734,185 shares of common stock at an average price of $7.31 per share.

On October 28, 2014, First Commonwealth Financial Corporation declared a quarterly dividend of $0.07 per share payable on November 21, 2014 to shareholders of record as of November 10, 2014. 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.

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 “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, cash flows and changes in shareholders’ equity as of and for the periods presented.

The results of operations for the nine months endedSeptember 30, 2014 are not necessarily indicative of the results that may be expected for the full year of 2014. These interim financial statements should be read in conjunction with First Commonwealth’s 2013 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.

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.

The overall effect was to increase the yield on the investment portfolio by 7 basis points, while only extending the overall duration of the entire portfolio by 2.4 months.

Accounting Changes and Error Corrections [Abstract]

New Accounting Pronouncements

New Accounting Pronouncements

In January 2014, the FASB issued ASU 2014-01, "Investments - Equity Method and Joint Ventures (Topic 323)," which permits reporting entities to make an accounting policy election to account for their investments in qualified affordable housing projects using the proportional amortization method if certain conditions are met. The proportional amortization method allows an entity to amortize the initial cost of the investment in proportion to the tax credits and other tax benefits received and recognizes the net investment performance in the income statement as a component of income tax expense (benefit). This amendment is effective for interim and annual periods beginning after December 15, 2014. The adoption of this ASU is not expected to have a material impact on First Commonwealth’s financial condition or results of operations.

In January 2014, the FASB issued ASU 2014-04, "Receivables - Troubled Debt Restructurings by Creditors (Subtopic 310-40)." This amendment clarifies that an in-substance repossession or foreclosure occurs and a creditor is considered to have received physical possession of property upon either, 1. the creditor obtaining legal title to the residential real estate property upon completion of a foreclosure, or 2. the borrower conveying all interest in the residential real estate property to the creditor to satisfy that loan through completion of a deed in lieu of foreclosure or through a similar legal agreement. Interim and annual disclosure of both the amount of foreclosed residential real estate property held by the creditor and the recorded investment in consumer mortgage loans collateralized by residential real estate property that are in the process of foreclosure according to local requirements of the applicable jurisdiction are required. This amendment is effective for annual periods beginning after December 15, 2014 and for interim periods within annual periods 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.

In April 2014, the FASB issued ASU 2014-08, “Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360)." This amendment changes the reporting requirements for discontinued operations. A disposal of a component of an entity or group of components of an entity is required to be reported in discontinued operations if the disposal represents a strategic shift resulting in a major effect on the entity's operations and financial results when any of the following occurs: 1. the component or group of components of an entity meets the criteria to be classified as held for sale, 2. the component or group of components of an entity is disposed of by sale, or 3. the component or group of components of an entity is disposed of other than by sale. If one of these criteria are met, the entity will present the assets and liabilities of a disposal group that includes a discontinued operation separately in the asset and liability sections of the statement of financial position for each comparative period along with additional footnote disclosure. This amendment is effective for annual periods beginning on or after December 15, 2014 and interim periods within annual periods beginning on or 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.

In May 2014, the FASB issued Update No. 2014-09, "Revenue from Contracts with Customers (Topic 606)." The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve that core principle, an entity should: 1) identify the contract(s) with a customer, 2) identify the performance obligations in the contract, 3) determine the transaction price, 4) allocate the transaction price to the performance obligations in the contract, and 5) recognize revenue when (or as) the entity satisfies a performance obligation. This update is effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period, and early adoption is not permitted. The adoption of this ASU is not expected to have a material impact on First Commonwealth’s financial condition or results of operations.

In June 2014, the FASB issued ASU 2014-11, "Transfers and Servicing (Topic 860)," which requires two accounting changes. One changes the accounting for repurchase-to-maturity transactions to secured borrowing accounting and the other requires separate accounting for a transfer of a financial asset executed contemporaneously with a repurchase agreement with the same counterparty in regards to repurchase financing arrangements, which will result in secured borrowing accounting for the repurchase agreement. The Update requires disclosure for certain transactions comprising a transfer of a financial asset accounted for as a sale and an agreement with the same transferee entered into in contemplation of the initial transfer that results in the transferor retaining substantially all of the exposure to economic return. The amendment also requires disclosure for repurchase agreements, securities lending transactions, and repurchase-to-maturity transactions that are accounted for as secured borrowings. This amendment will be effective for public entities for the first interim or annual period beginning after December 15, 2014. The adoption of this ASU is not expected to have a material impact on First Commonwealth’s financial condition or results of operations.

In June 2014, the FASB issued ASU 2014-12, "Compensation - Stock Compensation (Topic 718)," which requires that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. As such, the performance target should not be reflected in estimating the grant-date fair value of the award. Compensation cost should be recognized in the period in which it becomes probable that the performance target will be achieved and should represent the compensation cost attributable to the period(s) for which the requisite service has already been rendered. If the performance target becomes probable of being achieved before the end of the requisite service period, the remaining unrecognized compensation cost should be recognized prospectively over the remaining requisite service period. This amendment is effective for annual periods and interim periods within those annual periods beginning after December 15, 2015 with earlier adoption permitted. The adoption of this ASU is not expected to have a material impact on First Commonwealth’s financial condition or results of operations.

In August 2014, the FASB issued ASU No. 2014-14. "Receivables – Troubled Debt Restructurings by Creditors (Subtopic 310-40): Classification of Certain Government-Guaranteed Mortgage Loans upon Foreclosure." These amendments address the diversity in practice regarding the classification and measurement of foreclosed loans which were part of a government-sponsored loan guarantee program (e.g. HUD, FHA, VA). The ASU outlines certain criteria that, if met, the loan (residential or commercial) should be derecognized and a separate other receivable should be recorded upon foreclosure at the amount of the loan balance (principal and interest) expected to be recovered from the guarantor. This ASU will be effective for annual reporting periods beginning after December 15, 2014, including interim periods within that reporting period. Early adoption is permitted, provided the entity has adopted ASU 2014-04. The ASU should be adopted either prospectively or on a modified retrospective basis. The adoption of this ASU is not expected to have a material impact on First Commonwealth’s financial condition or results of operations.

In August 2014, the FASB issued ASU 2014-15, "Presentation of Financial Statements - Going Concern (Topic 205-40)," which requires management to evaluate, for each annual and interim period, whether conditions or events, considered in the aggregate, raise substantial doubt about the entity's ability to continue as a going concern within one year after the date that the financial statements are issued. When management identifies conditions or events that raise substantial doubt regarding an entity's ability to continue as a going concern, management should consider whether its plans that are intended to mitigate those relevant conditions or events will alleviate the substantial doubt. Certain footnote disclosures are required, the nature of which depends on if substantial doubt is alleviated as a result of consideration of management's plan. This amendment is effective for the annual period ending after December 15, 2016 and for annual and interim periods thereafter. The adoption of this ASU is not expected to have a material impact on First Commonwealth’s financial condition or results of operations.

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 adversely 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 Bank’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 September 30, 2014. 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 September 30, 2014 and December 31, 2013. 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 become 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 doubtful.

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 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.

Nonperforming loans decreased$14.1 million during the nine months endedSeptember 30, 2014. Contributing to this decrease was the sale of four real estate construction loans totaling $3.0 million and the payoff of six loans totaling $12.5 million. The payoffs included a $4.7 million commercial relationship to a local developer, a $3.1 million commercial real estate loan with a non-profit organization in western Pennsylvania, a $2.9 million commercial real estate loan to a real estate investor in western Pennsylvania, a $0.9 million residential real estate loan in western Pennsylvania, a $0.6 million commercial relationship with a western Pennsylvania glass manufacturer and a $0.3 million commercial real estate loan with a western Pennsylvania real estate investor. Additionally, net charge-offs recognized during the nine-months ended September 30, 2014 totaled $12.1 million including $5.8 million for a commercial industrial loan relationship with a gas drilling business that operated in western Pennsylvania with headquarters in Louisiana and $0.6 million for a commercial loan in western Pennsylvania. The remaining charge-offs were individually for amounts of $0.5 million or less.

Offsetting the previously noted decreases in nonperforming loans is a total of $19.8 million in loans which were moved into nonaccrual status during the nine months endedSeptember 30, 2014, the majority of which relates to a $4.3 million commercial industrial relationship with an audio visual equipment distributor, a $0.7 million commercial real estate relationship with a personal care facility in western Pennsylvania, and a $0.7 million commercial real estate relationship with a western Pennsylvania funeral home. In addition to this, $3.2 million in consumer loans which were 150 days or more past due were moved to nonaccrual status.

The specific allowance for nonperforming loans decreased by $4.2 million at September 30, 2014 compared to December 31, 2013, primarily due to the charge-offs noted on the previously mentioned loans offset by specific reserves recognized on the loans transferred into nonaccrual status. Unfunded commitments related to nonperforming loans were $0.4 million at September 30, 2014 and after consideration of available collateral related to these commitments, a reserve of $14 thousand was established was established for these off balance sheet exposures.

There were $1.3 million loans held for sale at September 30, 2014, all of which were 1-4 family residential loans originated through our recently launched mortgage business. There were no loans held for sale at December 31, 2013. Sales of loans during the nine months endedSeptember 30, 2014 and 2013 resulted in gains of $0.1 million and $0.6 million, respectively.

Significant nonaccrual loans as of September 30, 2014, include the following:

• $10.6 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. One of these loans, totaling $2.7 million, was modified, resulting in TDR classification in the second quarter of 2012. A second of these loans, totaling $0.3 million, was modified, resulting in TDR classification in the first quarter of 2013. During the nine months endedSeptember 30, 2014, chargeoffs of $0.5 million related to this relationship were recorded. A valuation of the collateral was completed during the third quarter of 2013, with updates to significant inputs completed in June 2014.

• $3.9 million in commercial industrial loans to an audio visual equipment distributor. These loans were originated in 2008 and refinanced by the Company in 2013. In the second quarter of 2014, the loans were placed on nonaccrual status. An updated valuation of the collateral was completed during the second quarter of 2014.

• $3.0 million in commercial real estate and industrial loans to a specialty metal processor in western Pennsylvania. These loans were originated in 2003 and were placed on nonaccrual status in the second quarter of 2013. The assets collateralizing this relationship as well as the appraisal for the real estate collateral were valued in the second quarter of 2014.

At September 30, 2014, troubled debt restructured loans decreased$12.5 million compared to December 31, 2013, and commitments related to troubled debt restructured loans increased$0.5 million for the same period. This decrease in loans is primarily a result of the payoff of four commercial loans totaling $11.3 million, including a $4.7 million commercial relationship with a local real estate developer, a $3.1 million commercial real estate loan with a non-profit organization and a $2.9 million commercial real estate loan in western Pennsylvania. The increase in unused line of credit commitments is related to two commercial borrowers.

The change in the unallocated portion of the allowance for credit losses comparing September 30, 2014 with September 30, 2013 is a result of the unallocated portion of the allowance for credit losses no longer being treated as a separate component of the allowance as of December 31, 2013. Instead it is incorporated into the reserve provided for each loan category. This portion of the allowance for credit losses reflects the qualitative or environmental factors that are probable to cause estimated credit losses to differ from historical loss experience.

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, interest rate derivatives that include 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 are comprised of FHLB stock whose estimated fair value is based on its par value. Additional information on FHLB stock is provided in Note 8, “Impairment of Investment Securities.”

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 12, “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 2014, 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 U.S. 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 8, “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	$29,456	Discounted Cash Flow	Probability of default	0% - 100% (18.02%)
			Prepayment rates	0% - 100% (6.61%)
			Discount rates	5.25% - 14.00% (a)
Equities	1,420	Par Value	N/A	N/A
Interest Rate Swap	—	Option model	Counterparty credit risk	3.69% - 6.82% (b)
Impaired Loans	5,934 (c)	Reserve study	Discount rate	10.00%
			Gas per MCF	$3.84 - $6.45 (d)
			Oil per BBL/d	$83.64 - $107.00 (d)
			NGL per gallon	$0.83 (d)
	113 (c)	Discounted Cash Flow	Discount Rate	9.00%
Other Real Estate Owned	190	Internal Valuation	N/A	N/A

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

(b) represents the range of the credit spread curve used in valuation.

(c) 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.

(d) 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 higher fair value measurement. Other unobservable inputs in the fair value measurement of impaired loans relate to gas, oil and natural gas prices and increases in these rates 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.

The significant unobservable input used in the fair value measurement of interest rate swaps classified as Level 3 is counterparty credit risk and the resulting range of the credit spread curve used in the valuation. Higher credit risk would result in an increased credit spread, which would reduce the fair value of the interest rate swap.

For the nine months endedSeptember 30, 2014 and 2013, there were no transfers between fair value Levels 1 and 2. However, $3.0 million and $20.1 million of loans were transferred into Level 3 from Level 2 during the nine months endedSeptember 30, 2014 and 2013, respectively, 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 September 30, 2014 and 2013.

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

	2014

For the three months endedSeptember 30, 2014 and 2013, there were no transfers between fair value Levels 1 and 2. Additional proceeds from a loan sale in the second quarter of 2013 resulted in a $0.2 million gain for the three months ended September 30, 2013. There were no gains or losses included in earnings for periods presented that are attributable to the change in realized gains(losses) relating to assets held at September 30, 2014 and 2013.

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

	September 30, 2014
	Level 1		Level 2		Level 3		Total

Total Assets	$	—	$	49,655	$	13,828	$	63,483

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

	For the Three Months Ended September 30,						For the Nine Months Ended September 30,
	2014			2013			2014			2013
	(dollars in thousands)
Impaired loans	$	456		$	(1,468	)	$	(1,291	)	$	(13,063	)
Other real estate owned	(51		)	(90		)	(1,109		)	(188		)
Total losses	$	405		$	(1,558	)	$	(2,400	)	$	(13,251	)

Impaired loans over $0.1 million 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 $7.8 million as of September 30, 2014 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 13, “Goodwill.” There were no other assets or liabilities measured at fair value on a non-recurring basis during the nine months endedSeptember 30, 2014.

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 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.”

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 $0.1 million at September 30, 2014 and December 31, 2013, respectively. See Note 6, “Commitments and Contingent Liabilities,” for additional information.

Deposit liabilities: 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:

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.

The amortized cost and estimated fair value of debt securities available for sale at September 30, 2014, by contractual maturity, are shown below.

During the third quarter of 2014, $132.9 million million in available for sale securities were sold as part of a strategy to protect the Company's net interest margin from the effects of a prolonged low interest rate enviroment. Proceeds from the investment sales were reinvested into like securities with a slightly longer duration and higher yield. The overall effect was to increase the yield on the investment portfolio by 7 basis points, while only extending the overall duration of the entire portfolio by 2.4 months.

Securities available for sale with an estimated fair value of $547.1 million and $594.9 million were pledged as of September 30, 2014 and December 31, 2013, respectively, to secure public deposits and for other purposes required or permitted by law.

Variable Interest Entities [Abstract]

Variable Interest Entities

Variable Interest Entities

As defined by Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 810-10, a Variable Interest Entity (“VIE”) is a corporation, partnership, trust or any other legal structure used for business purposes that either (a) does not have equity investors with voting rights or (b) has equity investors that do not provide sufficient financial resources for the entity to support its activities. Under ASC 810-10, an entity that holds a variable interest in a VIE is required to consolidate the VIE if the entity is deemed to be the primary beneficiary, which generally means it is subject to a majority of the risk of loss from the VIE’s activities, is entitled to receive a majority of the entity’s residual returns, or both.

First Commonwealth’s VIEs are evaluated under the guidance included in FASB Accounting Standards Update (“ASU”) 2009-17. These VIEs include qualified affordable housing projects that First Commonwealth has invested in as part of its community reinvestment initiatives. We periodically assess whether or not our variable interests in the VIE, based on qualitative analysis, provide us with a controlling interest in the VIE. The analysis includes an assessment of the characteristics of the VIE. We do not have a controlling financial interest in the VIE, which would require consolidation of the VIE, as we do not have the following characteristics: (1) the power to direct the activities that most significantly impact the VIE’s economic performance; and (2) the obligation to absorb losses or the right to receive benefits from the VIE that could potentially be significant to the VIE.

First Commonwealth’s maximum potential exposure is equal to its carrying value and is summarized in the table below:

Commitments and Contingencies Disclosure [Abstract]

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:

	September 30, 2014		December 31, 2013
	(dollars in thousands)
Financial instruments whose contract amounts represent credit risk:
Commitments to extend credit	$	1,644,486	$	1,571,987
Financial standby letters of credit	29,379		38,121
Performance standby letters of credit	26,210		32,441
Commercial letters of credit	2,405		—

The notional amounts outstanding as of September 30, 2014 include amounts issued in 2014 of $0.3 million in financial standby letters of credit and $0.8 million in performance standby letters of credit. There were $0.2 million commercial letters of credit issued during 2014. A liability of $0.1 million has been recorded as of September 30, 2014 and December 31, 2013, 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 $2.9 million as of September 30, 2014 and $3.2 million as of December 31, 2013. 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

Market Rate Savings IRA Litigation

McGrogan v. First Commonwealth Bank was filed as a class action on January 12, 2009, in the Court of Common Pleas of Allegheny County, Pennsylvania. The action alleges that First Commonwealth Bank (the “Bank”) promised class members a minimum interest rate of 8% on its IRA Market Rate Savings Account for as long as the class members kept their money on deposit in the IRA account. The class asserted that the Bank committed fraud, breached its modified contract with the class members, and violated the Pennsylvania Unfair Trade Practice and Consumer Protection Law ("UTPCPL") when it resigned as custodian of the IRA Market Rate Savings Accounts in 2008 and offered the class members a roll-over IRA account with a 3.5% interest rate. Plaintiffs sought monetary damages for the alleged breach of contract, punitive damages for the alleged fraud and Unfair Trade Practice and Consumer Protection Law violations and attorney’s fees. The court ruled that the IRA contract only guaranteed the 8% return until the 90-day or 18-month maturity of each instrument. The court granted class certification as to the breach of modified contract claim and denied class certification as to the fraud and Pennsylvania Unfair Trade Practice and Consumer Protection Law claims. The breach of contract claim was predicated upon a letter sent to customers in 1998 which reversed an earlier decision by the Bank to reduce the rate paid on the accounts. The letter stated, in relevant part, “This letter will serve as notification that a decision has been made to re-establish the rate on your account to eight percent (8)%. This rate will be retroactive to your most recent maturity date and will continue going forward on deposits presently in the account and on annual additions.” On August 30, 2012, the Court entered an order granting the Bank’s motion for summary judgment and dismissed the class action claims. The Court found that the Bank retained the right to resign as custodian of the accounts and that the act of resigning as custodian and closing the accounts did not breach the terms of the underlying IRA contract. On appeal, the Superior Court affirmed the denial of class certification to the claims of fraud in the execution and violation of the UTPCPL. The Superior Court found that none of the other issues were ripe for appeal. Jurisdiction was returned to the Court of Common Pleas where the individual fraud and UTPCPL claims of Mr. and Mrs. McGrogan are pending. Plaintiffs filed their pretrial statement on June 16, 2014, seeking $0.5 million in damages for the McGrogans and $0.8 million for their adult children beneficiaries. The Bank considers these damage claims exaggerated and otherwise invalid. The Bank has filed a motion for summary judgment, which was granted as to the claims of the adult children beneficiaries. The case is scheduled for trial on January 20, 2015.

In December 2013, three new complaints were filed by 34 former members of the McGrogan class:

(1) Jarrett et al. v. First Commonwealth Bank - An action filed by eight plaintiffs on December 2, 2013 in the Westmoreland County Court of Common Pleas asserting claims for fraud in the inducement, fraud in the execution, violation of the UTPCPL, breach of fiduciary duty and promissory estoppel.

(2) Young et al. v. First Commonwealth Bank - An action filed by 12 plaintiffs on December 2, 2013 in the Westmoreland County Court of Common Pleas asserting claims for fraud in the inducement, fraud in the execution, violation of the UTPCPL, breach of fiduciary duty and promissory estoppel.

(3) Fisanik et. al. v. First Commonwealth Bank - An action filed by 14 plaintiffs on December 9, 2013 in the Cambria County Court of Common Pleas asserting claims for fraud in the inducement, fraud in the execution, violation of the UTPCPL, and breach of fiduciary duty.

The 36 plaintiffs who have filed individual actions held Market Rate Savings IRA balances totaling approximately $4 million at the time of the Bank’s resignation as custodian of the IRAs in 2008-09. The average age of the plaintiffs at that time was 62.

The Bank filed preliminary objections to the three new complaints. On July 22, 2014 the court issued an order permitting the three new cases to proceed only on theories of fraud in the execution and violation of the UTPCPL based on fraud in the execution and dismissing the claims for fraud in the inducement, breach of fiduciary duty and promissory estoppel with prejudice. Discovery in the three actions is beginning.

At this time, the Bank believes the claims are without merit.

Other matters

In 2013, First Commonwealth identified an error related to historical tax reporting for approximately 700-900 customers, resulting in the establishment of a $0.8 million contingency reserve. During the second quarter of 2014, a settlement in the amount of $0.4 million was reached with one taxing authority, while resolution with another taxing authority continues. Based on the settlement reached, management's best estimate of the remaining liability for this issue is $0.1 million. As a result, in addition to the settlement amount, $0.3 million of the contingency reserve was reversed during the second quarter of 2014. The contingency reserve is included in “Other liabilities” in the Condensed Consolidated Statements of Financial Condition.

There are no other 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 or cash flow of First Commonwealth or its subsidiaries.

Impairment of Investment Securities Disclosure [Abstract]

Impairment of Investment Securities

Impairment of Investment Securities

Securities Available for Sale

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 nine months endedSeptember 30, 2014 and 2013, 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 11, “Fair Values of Assets and Liabilities,” for additional information.

The following table presents the gross unrealized losses and estimated fair values at September 30, 2014 by investment category and time frame for which securities have been in a continuous unrealized loss position:

Pooled trust preferred collateralized debt obligations accounted for 42% of the unrealized losses due to changes in market interest rates and the illiquid market for this investment type. There were no equity securities in an unrealized loss position at September 30, 2014.

The following table presents the gross unrealized losses and estimated fair values at December 31, 2013 by investment category and time frame for which securities have been in a continuous unrealized loss position:

As of September 30, 2014, our corporate securities had an amortized cost and an estimated fair value of $6.7 million and $7.3 million, respectively, and were comprised of single issue trust preferred securities issued primarily by large regional banks. As of December 31, 2013, the same portion of the portfolio had an amortized cost of $6.7 million and an estimated fair value of $7.0 million. There were no corporate securities in an unrealized loss position as of September 30, 2014 and December 31, 2013. 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 September 30, 2014, the book value of our pooled trust preferred collateralized debt obligations totaled $42.0 million with an estimated fair value of $29.5 million, which includes securities comprised of 282 banks and other financial institutions. All of our pooled securities are mezzanine tranches, four 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 September 30, 2014, after taking into account management’s best estimates of future interest deferrals and defaults, five of our securities had no excess subordination in the tranches we own and five of our securities had excess subordination which ranged from 2% to 43% of the current performing collateral.

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 three and nine months endedSeptember 30, 2014 and 2013, 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 September 30, 2014. 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 282 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 September 30, 2014, 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 which 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 September 30, 2014, indicates that no credit related other-than-temporary impairment has occurred on our pooled trust preferred securities during the nine months endedSeptember 30, 2014. Based upon the analysis performed by management, it is probable that five 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 September 30, 2014 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 September 30, 2014, 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 22% to 154% 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 are 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:

(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 nine months of 2014 and 2013, 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 September 30, 2014 and 2013, there are 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 September 30, 2014 and December 31, 2013, our FHLB stock totaled $51.0 million and $35.4 million, respectively and is included in “Other investments” on the Condensed Consolidated Statements of Financial Condition.

Beginning in July 2013, the FHLB began repurchasing 100% of a member's excess stock on a monthly basis. In the months prior to that in 2013, the FHLB repurchased the lessor of 5% of the members' total capital stock outstanding or its total excess capital stock on a quarterly basis. As a result, during the nine months endedSeptember 30, 2014 and 2013, $16.6 million and $9.9 million, respectively, of the stock owned by First Commonwealth was repurchased. The FHLB repurchased stock and paid dividends in 2014 and 2013, however, decisions regarding any future repurchase of excess capital stock and dividend payments will be made by the FHLB on an ongoing basis.

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. The decision of whether impairment exists is a matter of judgment that reflects our view of the FHLB’s long-term performance, which includes factors such as the following:

• its operating performance;

• the severity and duration of declines in the fair value of its net assets related to its capital stock amount;

• its commitment to make payments required by law or regulation and the level of such payments in relation to its operating performance;

• the impact of legislative and regulatory changes on the FHLB, and accordingly, on the members of FHLB; and

• its liquidity and funding position.

After evaluating all of these considerations, First Commonwealth concluded that the par value of its investment in FHLB stock will be recovered. Accordingly, no impairment charge was recorded on these securities for the nine months endedSeptember 30, 2014. Our evaluation of the factors described above in future periods could result in the recognition of impairment charges on FHLB stock.

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 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.

First Commonwealth is considered to be one reporting unit. The carrying amount of goodwill as of September 30, 2014 and December 31, 2013 was $159.4 million and $159.9 million, respectively. No impairment charges on goodwill or other intangible assets were incurred in 2014 or 2013. The $0.5 million decline in goodwill during the nine months ended September 30, 2014 represents the amount of goodwill included in the carrying value of the investment advisory business which was sold during the first quarter of 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. An assessment of qualitative factors was completed as of September 30, 2014 and indicated that it is more likely than not that the fair value of First Commonwealth exceeds its carrying amount, therefore the two step goodwill impairment test was not considered necessary. The assessment of qualitative factors incorporated the results of the Step 1 goodwill impairment test completed as of November 30, 2013 as well as macroeconomic factors, industry and market considerations, the company’s overall financial performance, and other company specific events occurring since the completion of the November 30, 2013 test.

As of September 30, 2014, goodwill was not considered impaired; however, changing economic conditions that may adversely affect our performance, fair value of our assets and liabilities, or 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.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivatives Not Designated as Hedging Instruments

First Commonwealth is a party to interest rate derivatives that are not designated as accounting hedges. These derivatives relate to interest rate swaps that First Commonwealth entered 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 thirteen 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 four 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 providing 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

During the third quarter of 2014, the Company entered into two interest rate swap contracts which were designated as cash flow hedges. Both of the interest rate swaps have a notional amount of $50.0 million with a maturity of three years on one and four years on the other. 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 $100.0 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 Statement of Income. For the three and nine months ended September 30, 2014, there was no 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 Statement of Income as the income on the hedged items. The cash flow hedges were highly effective at September 30, 2014, and changes in the fair value attributed to hedge ineffectiveness were not material. There were no cash flow hedges at December 31, 2013.

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:
