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 ended September 30, 2012 are not necessarily indicative of the results that may be expected for the full year of 2012. These interim financial statements should be read in conjunction with First Commonwealth’s 2011 Annual Report on Form 10-K which is available on First Commonwealth’s website at http://www.fcbanking.com.

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,		December 31,
	2012		2011
	(dollars in thousands)
Financial instruments whose contract amounts represent credit risk:

Commitments and letters of credit (Continued)

The current notional amounts outstanding as of September 30, 2012 include financial standby letters of credit of $0.3 million, performance standby letters of credit of $19.5 million, and commercial letters of credit $0.4 million issued during the first nine months of 2012. A liability of $0.2 million and $0.1 million has been recorded as of September 30, 2012 and December 31, 2011, respectively, 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 in these commitments resulted in the recording of a liability of $2.1 million as of September 30, 2012 and $1.5 million as of December 31, 2011. 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

McGrogan v. First Commonwealth Bank is a class action that was filed 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 asserts that the Bank committed fraud, breached its modified contract with the class members, and violated the Pennsylvania Unfair Trade Practice and Consumer Protection Law 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. At that time, there were 237 account holders with an average age of 64, and the aggregate balances in the IRA Market Rate Savings accounts totaled approximately $11.5 million. Plaintiffs seek 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. On July 27, 2011, 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 is 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 dismissing 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. The Plaintiffs have filed an appeal with the Pennsylvania Superior Court.

Other matters

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 or financial position of First Commonwealth or its subsidiaries.

Note 8 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. 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, 2012 and December 31, 2011, our FHLB stock totaled $32.5 million and $39.8 million, respectively and is included in “Other investments” on the Condensed Consolidated Statements of Financial Condition.

During 2012 and 2011, the FHLB repurchased excess stock from its members by repurchasing the lessor of 5% of the members’ total capital stock outstanding or its total excess capital stock. As a result, during the nine-months ended September 30, 2012 and 2011, stock repurchases occurred in the amounts of $7.3 million and $7.0 million, respectively. The FHLB repurchased stock and paid dividends in each quarter of 2012, however, decisions regarding any future repurchase of excess capital stock and dividend payments will be made by the FHLB on a quarterly basis. Management reviewed the FHLB’s Form 10-Q for the period ended June 30, 2012 filed with the SEC on August 8, 2012.

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

13

FIRST COMMONWEALTH FINANCIAL CORPORATION AND SUBSIDIARIES

ITEM 1. Financial Statements and Supplementary Data (Continued)

Notes to the Unaudited Condensed Consolidated Financial Statements (Continued)

Note 8 Other Investments (Continued)

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 ended September 30, 2012. Our evaluation of the factors described above in future periods could result in the recognition of impairment charges on FHLB stock.

Note 9 Impairment of Investment Securities

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 ended September 30, 2012 and 2011, no other-than-temporary impairment charges were recognized. For the nine-months ended September 30, 2012, $1.5 million in non-credit related gains on our trust preferred collateralized debt obligations that were determined to be impaired in previous periods was recorded in OCI. For the same period in 2011, $0.2 million in non-credit related losses for the same pool of securities was recorded in OCI. All of the securities for which other-than-temporary impairment was recorded were classified as available for sale securities.

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.

In the Condensed Consolidated Statements of Income, the “Changes in fair value on impaired securities” line represents the change in fair value of securities impaired in the current or previous periods. The change in fair value includes both non-credit and credit related gains or losses. Credit related losses occur when the entire amortized cost of the security will not be recovered. The “Non-credit related (gains) losses on securities not expected to be sold (recognized in other comprehensive income)” line represents the gains and losses on the securities resulting from factors other than credit. The non-credit related gain or loss is disclosed in the Condensed Consolidated Statements of Income and recognized through other comprehensive income. The “Net impairment losses” line represents the credit related losses recognized in total noninterest income for the related period.

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 12, “Fair Values of Assets and Liabilities,” for additional information.

(a) Gross unrealized losses related to these types of securities are less than $1 thousand.

At September 30, 2012, pooled trust preferred collateralized debt obligations accounted for almost all of the unrealized losses, while fixed income securities issued by U.S. Government-sponsored enterprises comprised less than one percent of total unrealized losses. There were no equity securities in an unrealized loss position at September 30, 2012.

As of September 30, 2012, our corporate securities had an amortized cost and an estimated fair value of $10.8 million and $11.1 million, respectively, and were comprised of single issue trust preferred securities issued primarily by money center and large regional banks. As of December 31, 2011, the same portion of the portfolio had an amortized cost of $11.8 million and an estimated fair value of $11.4 million. There were no corporate securities in an unrealized loss position as of September 30, 2012, while as of December 31, 2011, there were $0.6 million in unrealized losses related to these investments. When unrealized losses exist, management reviews each of the issuer’s asset quality, earnings trend and capital position, to determine whether issues in an unrealized

As of September 30, 2012, the book value of our pooled trust preferred collateralized debt obligations totaled $52.7 million with an estimated fair value of $23.1 million, which includes securities comprised of 339 banks and other financial institutions. Two of our pooled securities are senior tranches and the remainders are mezzanine tranches, three of which have no senior class remaining in the issue. Two of the pooled issues, representing $2.9 million of the $52.7 million book value, remain above 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, 2012, after taking into account management’s best estimates of future interest deferrals and defaults, six of our securities had no excess subordination in the tranches we own and seven of our securities had excess subordination which ranged from 10% to 566% of the current performing collateral.

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

On a quarterly basis we evaluate our debt securities for other-than-temporary impairment. During the nine-months ended September 30, 2012 and 2011, 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, 2012. We consider the discounted cash flow analysis to be our primary evidence when determining whether credit related other-than-temporary impairment exists.

Note 9 Impairment of Investment Securities (Continued)

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. For collateral issued by financial institutions with over $15 billion in asset size, we consider the alternative cost of funding and if that rate is less than the current rate being paid, we incorporate a prepayment in our estimate of future cash flows. The prepayment rates used are 20% in years 2 and 3 and a 2% prepayment rate thereafter. 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 339 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, 2012, 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 allows 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, 2012, indicates that no credit related other-than-temporary impairment has occurred on our pooled trust preferred securities during the nine-months ended September 30, 2012. Based upon the analysis performed by management, it is probable that six 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 17 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, 2012 indicates it is probable that we will collect all contractual principal and interest payments.

During 2008, 2009 and 2010, other-than-temporary impairment charges were recognized on all of our pooled trust preferred securities, except for PreTSL I, PreTSL IV and MMCap I-Senior. Our cash flow analysis as of September 30, 2012, 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 our current book value being below the present value of estimated future principal and interest payments. The excess for each bond of the present value of future cash flows over our current book value ranges from 14% to 144% and will be recognized as an adjustment to yield over the remaining life of these securities. During the three- and nine-months ended September 30, 2012, $0.4 million and $0.9 million, respectively, of the excess was recognized as an adjustment to yield on these securities.

The following 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 third quarter of 2012 and 2011, 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, 2012 and 2011, there are no equity securities in an unrealized loss position.

Loans to individuals		586,278		565,849
Total loans and leases net of unearned income		4,214,299	$	4,043,643

During the nine-months ended September 30, 2012, all loan categories, except commercial real estate, increased with total loans increasing $170.7 million or 4% compared to balances outstanding at December 31, 2011. A majority of the loan growth was recognized in the residential real estate portfolio as a result of seasonal demand and an ongoing loan promotion. Increases in commercial, financial, agricultural and other portfolio can be attributed to growth in direct middle market lending and syndications in Pennsylvania and contiguous states, while loans to individuals increased due to growth in home equity installment loans and indirect auto lending.

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. Movements 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

Credit quality measures at September 30, 2012 compared to December 31, 2011 indicate a decrease in criticized loans, or loans designated OAEM, substandard or doubtful, of $23.0 million, or 8%, a decrease in delinquency 30 days and over on accruing loans of $10.2 million, or 29%, and an $8.3 million increase in nonaccrual loans, excluding loans held-for-sale.

Charge-offs for the nine-months ended September 30, 2012 totaled $13.4 million compared to $30.1 million for the nine-months ended September 30, 2011. The most significant charge-offs during the nine-months ended September 30, 2012 were a $1.4 million charge taken on a Florida real estate construction loan with a remaining balance of $4.3 million and a $1.2 million charge taken on a $2.0 million commercial loan relationship. During the nine-months ended September 30, 2011, the most significant charge-off totaled $5.2 million and related to a central Pennsylvania development loan relationship. Other significant charge-offs during the nine-month period

in 2011 totaled $10.8 million and related to six construction loan projects located in Florida, Nevada, Ohio and western and central Pennsylvania.

Criticized loans totaled $269.0 million at September 30, 2012 and represented 6% of the loan portfolio. This represents a $23.0 million decrease compared with the portfolio as of December 31, 2011. These loans have been evaluated when determining the appropriateness of the allowance for credit losses, which we believe is adequate at this time. 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.

The credit quality of our loan portfolio represents significant risk to our earnings, capital, regulatory agency relationships and shareholder returns. First Commonwealth devotes a substantial amount of resources to 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.

Risk factors associated with commercial real estate and construction related loans are monitored closely since this is an area that represents a significant portion of the loan portfolio and has experienced the most stress during the economic downturn.

In addition, during the first nine months of 2012, nine relationships consisting of fifteen loans, were classified as troubled debt restructuring. These loans increased the nonperforming loan balance by $10.3 million with a $3.2 million increase in specific reserves.

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. In periods prior to the third quarter of 2012, if a consumer loan was well secured and in the process of collection, it remained on accrual status, as delinquency was not a factor in moving it to nonaccrual status.

Nonaccrual Loans

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.

Impaired Loans (Continued)

Nonperforming loans, excluding loans held for sale, decreased $4.9 million to $93.9 million at September 30, 2012 compared to $98.8 million at December 31, 2011. Contributing to this decrease was an $11.3 million loan to a waste management company which was paid off in the first quarter and a $10.3 million loan to an information technology firm which was returned to accrual status in the second quarter. The most significant loans placed into nonperforming status during the first nine months of 2012 included $6.7 million to a western Pennsylvania in-patient facility, $4.9 million for a commercial real estate loan to a nonprofit institution, $2.5 million to a manufacturer of medical equipment and $2.8 million to a western Pennsylvania construction firm. During the third quarter of 2012, a $0.9 million payment was received on the aforementioned $4.9 million loan to a nonprofit, providing for a current balance on this loan of $3.9 million. Also impacting the balance of nonperforming loans for the period was the movement to nonaccrual status of $4.8 million in consumer loans which were 150 days or more past due. Beginning in the third quarter of 2012, consumer loans are moved to nonaccrual status once they reach 150 days past due, however, in prior periods, these loans were not placed in nonaccrual status if they were well secured and in the process of collection. The majority of the consumer loans moved to nonaccrual status in the third quarter, or $4.7 million of the $4.8 million, were residential real estate loans.

The specific allowance for nonperforming loans decreased by $0.3 million at September 30, 2012 compared to December 31, 2011, primarily due to the decrease in balances. Unfunded commitments related to nonperforming loans were $5.1 million at September 30, 2012 and after consideration of available collateral related to these commitments, an off balance sheet reserve of $44 thousand was established.

Loans held for sale totaled $13.4 million at December 31, 2011 and the entire balance represented nonperforming loans. As of September 30, 2012, the sale of all of these loans had been completed and provided for a $2.9 million gain. While these loans were considered to be nonperforming, they were not taken into consideration when determining the allowance for credit losses as they were carried at the lower of cost or fair value.

Significant nonaccrual loans as of September 30, 2012, include the following;

• $19.3 million, the remaining portion of a $44.1 million unsecured loan to a western Pennsylvania real estate developer. This loan was originated in the second quarter of 2004 and was placed in nonaccrual status in the fourth quarter of 2009. A settlement plan with the borrower and three other lenders was reached in the fourth quarter of 2010 and resulted in an $8.0 million principal payment and a $15.4 million partial charge-off.

• $16.0 million commercial real estate loan for a real estate developer in eastern Pennsylvania. This loan was originated in the third quarter of 2007 and restructured in the fourth quarter of 2011which resulted in a charge-off of $4.2 million. The most recent appraisal for the real estate collateral was completed in the third quarter of 2011.

• $6.7 million commercial real estate loan to an in-patient facility in western Pennsylvania. This loan was originated in the fourth quarter of 2008 and placed in nonaccrual status in September 2012. Because this loan was not previously classified, the most recent appraisal for the real estate collateral was at loan origination. Therefore, the collateral valuation and resulting shortfall on this loan were determined using a real estate common level ratio.

• $4.3 million, the remaining portion of a $20.8 million construction loan for a Florida condominium project. This loan was originated in the second quarter of 2007. Charge-offs of $16.5 million have been recorded on this loan. The most recent appraisal for the real estate collateral was completed in the second quarter of 2012.

• $3.9 million real estate secured loan to a western Pennsylvania nonprofit corporation. This loan was originated in the fourth quarter of 2008 and placed in nonaccrual status in the second quarter of 2012. The most recent appraisals for the various real estate collateral were completed in the fourth quarter of 2011 and the first quarter of 2012.

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 financial difficulties experienced by the borrower, who could not obtain comparable terms from alternate financing sources.

The following table provides detail as to the total troubled debt restructured loans and total commitments outstanding on troubled debt restructured loans:

	September 30, 2012		December 31, 2011

Unused lines of credit		1,342		42
Total	$	1,342	$	12,622

At September 30, 2012, troubled debt restructured loans on accruing status decreased $13.1 million compared to December 31, 2011 and commitments related to troubled debt restructured loans decreased $11.3 million for the same period. These decreases are primarily a result of the payoff of an $11.3 million loan to a waste management company in Pennsylvania as a result of the sale of the business. In addition, a $2.2 million loan to a retail development company in western Pennsylvania paid off during the first quarter. During 2012 and 2011 the changes in loan balances between the pre-modification balance and the post-modification balance are due to customer payments.

Note 12 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.

Note 12 Fair Values of Assets and Liabilities (Continued)

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, certain corporate securities, FHLB stock, interest rate derivatives that include 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 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 fair value is based on its par value. Additional information on FHLB stock is provided in Note 8, “Other Investments.”

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. First Commonwealth values its interest rate swap 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 13, “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

32

ITEM 1. Financial Statements and Supplementary Data (Continued)

Notes to the Unaudited Condensed Consolidated Financial Statements (Continued)

Note 12 Fair Values of Assets and Liabilities (Continued)

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 2012, we have not realized any losses due to a counterparty’s inability to pay any net uncollateralized position.

The 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, loans held for sale and 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 was more appropriate to determine 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 9, “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.

Loans held for sale are carried at the lower of cost or fair value with the fair value being the expected sales price of the loan. The estimated fair value of the loans held for sale was determined by calculating the discounted expected future cash flows of the loan. The discount rate applied to the future cash flows was determined based on a risk based expected return and capital structure of potential buyers. If a sales agreement has been executed, the fair value is equal to the sales price.

Note 12 Fair Values of Assets and Liabilities (Continued)

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 2012, we have not realized any losses due to a counterparty’s inability to pay any net uncollateralized position. However, as the result of deterioration in the counterparties (loan customers) credit quality for certain interest rate derivatives, future amounts previously believed to be collectible under the terms of the interest rate derivative have now been deemed to be uncollectible.

In accordance with ASU 2011-04, 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	$23,051	Discounted Cash Flow	Probability of default	0% -100% (21.73%)
			Prepayment rates	0% -100% (13.44%)
			Discount rates	6.75% - 20%(a)
Other Investments	1,420	Par Value	N/A	N/A
Interest Rate Swap	0	Option model	Counterparty credit risk	15.08% - 17.63%(b)
Impaired Loans	15,755(c)	Discounted Cash Flow	Discount rate	8.42% - 8.83%
Other Real Estate Owned	338	Internal Valuation	N/A	N/A

(a) incorporates premium related 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.

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.

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 ended September 30, 2012, there were no transfers between fair value Levels 1 and 2. However, $0.5 million of interest rate swaps were transferred into Level 3 from Level 2 due to deterioration of the counterparty’s credit risk. Because the credit quality of the underlying counterparty declined below investment grade, the swaps were valued utilizing more than interest rate yield curves. During the second quarter of 2011, $12.0 million of corporate securities were transferred from Level 3 to Level 2. Corporate securities were transferred from Level 3 to Level 2 based on increased frequency in the volume of observable trades. Fair values

on these securities at September 30, 2011 were determined based on market data, including trade and bid prices. During the third quarter of 2011, $4.5 million of interest rate swaps were transferred into Level 3 from Level 2 also due to deterioration of the counterparty’s credit risk. 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, 2012 and 2011.

Note 12 Fair Values of Assets and Liabilities (Continued)

For the three-months ended September 30, 2012, there were no transfers of securities between Levels 1, 2 or 3. During the third quarter of 2011, $4.5 million of interest rate swaps were transferred into Level 3 from Level 2 due to deterioration of the counterparty’s credit risk. 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, 2012 and 2011.

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

The following 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,
	2012			2011			2012			2011

Total losses	$	(4,256	)	$	(7,236	)	$	(7,875	)	$	(32,260	)

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. 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.

The fair value for other real estate owned is determined by either an independent market based appraisal less estimated costs to sell or an executed sales agreement and is classified as Level 2. Other real estate owned has a book cost of $16.0 million as of September 30, 2012 and consisted primarily of a manufacturing plant in northern Pennsylvania, residential real estate in eastern Pennsylvania and a commercial real estate property in eastern Pennsylvania. During the first quarter of 2012, the sale of an office building in western Pennsylvania which was

Note 12 Fair Values of Assets and Liabilities (Continued)

previously in OREO for $6.8 million was completed and resulted in a $0.3 million loss at the time of sale. During the third quarter of 2012, a real estate property located in central Pennsylvania which was in OREO for $1.2 million was sold and resulted in a $0.6 million gain. 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 14, “Goodwill.” There were no other assets or liabilities measured at fair value on a non-recurring basis during the nine-months ended September 30, 2012.

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 held for sale: The fair value of loans held for sale is estimated utilizing a present value of future discounted cash flows of the loan utilizing a risk based expected return to discount the value unless a sales agreement has been executed, in which case the sales price would equal 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

39

FIRST COMMONWEALTH FINANCIAL CORPORATION AND SUBSIDIARIES

ITEM 1. Financial Statements and Supplementary Data (Continued)

Notes to the Unaudited Condensed Consolidated Financial Statements (Continued)

Note 12 Fair Values of Assets and Liabilities (Continued)

fair value of the obligation undertaken in issuing the guarantee. The carrying amount and fair value for standby letters of credit was $0.2 million and $0.1 million at September 30, 2012 and December 31, 2011, respectively. See Note 6, “Commitments and Contingent Liabilities,” for additional information.

Deposit liabilities: Management estimates that the fair value of deposits is based on a market valuation of similar deposits. 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 estimated incremental borrowing rate for similar types of borrowing arrangements.

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

Note 13 Derivatives

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 enters into with customers to allow customers to convert variable rate loans to a fixed rate. First Commonwealth pays interest to the customer at a floating rate on the notional amount and receives interest from the customer at a fixed rate for the same notional amount. At the same time the interest rate swap is entered into with the customer, an offsetting interest rate swap is entered into with another financial institution. First Commonwealth pays the other financial institution interest at the same fixed rate on the same notional amount as the swap entered into with the customer, and receives interest from the financial institution for the same floating rate on the same notional amount. The changes in the fair value of the swaps offset each other, except for the credit risk of the counterparties, which is determined by taking into consideration the risk rating, probability of default and loss of given default for all counterparties.

We have twelve 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.

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

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:

Increase (decrease) in other income	$	375	$	(5,108	)	$	1,126	$	(5,643	)

During 2012, total credit risk income of $1.3 million was recognized, offset by $0.2 million in expense related to three interest rate swaps that were downgraded during the third quarter to a below investment grade rating. As a result of the deterioration of credit risk related to the counterparty, a larger mark-to-market adjustment was recorded. The fair value of our derivatives is included in a table in Note 12 “Fair Values of Assets and Liabilities,” in the line items other assets and other liabilities.

Note 14 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 2011-08 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, 2012 and December 31, 2011 was $159.9 million. No impairment charges on goodwill or other intangible assets were incurred in 2012 or 2011.

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, 2012 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 2 goodwill impairment test completed as of December 31, 2011 as well as macroeconomic factors, industry and market considerations, the company’s overall financial performance, and other company specific events occurring during the first nine months of 2012.

As of September 30, 2012, 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.

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

Results of Operations

This discussion and the related financial data are presented to assist in the understanding and evaluation of the consolidated financial condition and the results of operations of First Commonwealth Financial Corporation including its subsidiaries (“First Commonwealth”) for the nine-months ended September 30, 2012 and 2011, and should be read in conjunction with the Condensed Consolidated Financial Statements and notes thereto included in this Form 10-Q.

Forward-Looking Statements

Certain statements contained in this report that are not historical facts may constitute “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and are intended to be covered by the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. 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:

• continued weakness in 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;

• 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;

• 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;

• further 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;

• legislative and regulatory changes, including the impact of the Dodd-Frank Wall Street Reform and Consumer Protection Act 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;

• 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

Forward-Looking Statements (Continued)

• other risks and uncertainties described in this report and in the other reports that we file with the Securities and Exchange Commission, including our most recent Annual Report on Form 10-K.

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

Explanation of Use of Non-GAAP Financial Measure

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

We believe the presentation of net interest income on a fully taxable equivalent basis ensures comparability of net interest income arising from both taxable and tax-exempt sources and is consistent with industry practice. Interest income per the Condensed Consolidated Statements of Income is reconciled to net interest income adjusted to a fully taxable equivalent basis on page 46 for the nine-months ended September 30, 2012 and 2011.

Results of Operations

Nine-Months Ended September 30, 2012 Compared to Nine-Months Ended September 30, 2011

Net Income

For the nine-months ended September 30, 2012, First Commonwealth had net income of $33.2 million, or $0.32 per share, compared to net income of $21.0 million or $0.20 per share in the nine-months ended September 30, 2011. The increase in net income is primarily the result of a lower provision for credit losses, receipt of a joint venture termination fee, positive market value adjustments for interest rate swaps and higher gains recognized on the sale of assets. These increases were offset by lower net security gains, increased salaries and employee benefit expenses and operational losses.

Net Interest Income

Net interest income, on a fully taxable equivalent basis, was $145.1 million in the first nine months of 2012 compared to $146.5 million for the same period in 2011. Net interest income comprises a majority of our operating revenue (net interest income before the provision plus noninterest income) at 73% and 77% for the nine-months ended September 30, 2012 and 2011, respectively.

Net interest margin, on a fully taxable equivalent basis, was 3.63% for the nine-months ended September 30, 2012 compared to 3.81% for the nine-months ended September 30, 2011. The net interest margin is affected by both changes in the level of interest rates and the amount and composition of interest-earning assets and interest-bearing liabilities.

Results of Operations (Continued)

Net Interest Income (Continued)

During the nine-months ended September 30, 2012, the net interest margin has been challenged by the continuing low interest rate environment and decreasing rates earned on interest-earning assets. Despite a disciplined approach to pricing which has provided for maintaining the level of new volume spreads, runoff of existing assets which are earning higher interest rates has continued to provide for lower yields on earning assets. Growth in earning assets has helped to offset the impact of runoff, as average earning assets for the nine months ended September 30, 2012 increased $202.6 million, or 4%, compared to the comparable period in 2011. It is expected that the challenges to the net interest margin will continue as $2.9 billion in interest-sensitive assets either reprice or mature over the next twelve months.

The taxable equivalent yield on interest-earning assets was 4.22% for the nine-months ended September 30, 2012, a decrease of 45 basis points from the 4.67% yield for the same period in 2011. This decline can be attributed to the repricing of our variable rate assets in a declining 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 0.73% for the nine-months ended September 30, 2012, compared to 1.04% for the same period in 2011. Also, impacting the net interest margin in the first nine months of 2012 was the recognition of $1.2 million in interest income related to loans that were previously in nonaccrual status. This contributed 3 basis points to the net interest margin for the nine-months ended September 30, 2012. Offsetting this contribution was the reversal of $0.7 million, or 2 basis points, of interest income related to loans that were placed in nonaccrual status during 2012.

Comparing the nine-months ended September 30, 2012 with the same period in 2011, changes in interest rates negatively impacted net interest income by $10.1 million. The lower yield on interest-earning assets adversely impacted net interest income by $17.3 million, while the decline in the cost of interest-bearing liabilities had a positive impact of $7.2 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 deposit and borrowed funds, disciplined pricing strategies, loan growth and increasing our investment volumes within established interest rate risk management guidelines.

While decreases in interest rates and yields compressed the net interest rate, increases in average interest-earning assets and low cost average interest-bearing liabilities neutralized the effect on net interest income. Changes in the volumes of interest-earning assets and interest-bearing liabilities positively impacted net interest income by $8.7 million in the nine-months ended September 30, 2012 compared to the same period in 2011. Higher levels of interest-earning assets resulted in an increase of $6.5 million in interest income, while volume changes primarily attributed to the mix of deposits reduced interest expense by $2.2 million.

Positively affecting net interest income was a $92.8 million increase in average net free funds at September 30, 2012 as compared to September 30, 2011. 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 as a result of marketing promotions aimed at attracting new and retaining existing customers. Additionally, higher costing time deposits continue to runoff and reprice to lower costing certificates or other deposit alternatives. Average time deposits for the nine months ended September 30, 2012 decreased $229.2 million, or 17%, compared to the comparable period in 2011. The positive change in deposit mix is expected to continue as $589.5 million in certificates of deposits either mature or reprice over the next twelve months.

Provision for Credit Losses

The provision for credit losses is determined based on management’s estimates of the appropriate level of allowance for credit losses needed to absorb probable losses inherent in the loan 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 ended September 30:

Unallocated		978		7			(197	)		(1	)
Total	$	14,838		100	%	$	29,904			100	%

The provision for credit losses for the nine-months ended September 30, 2012 decreased in comparison to the nine-months ended September 30, 2011, by $15.1 million or 50%. The provision for credit losses for the nine-months ended September 30, 2012, was slightly more than the $12.0 million in net credit losses for the period.

During the nine-months ended September 30, 2012, the most significant provision for credit losses related to a $3.3 million increase in specific reserves for a commercial real estate loan. The resulting increase in provision for that loan category was partially offset by the impact of lower outstanding commercial real estate loans. The provision for credit losses for commercial, financial, agricultural and real estate construction categories can be attributed primarily to growth in those portfolios. The $1.0 million unallocated provision for credit losses is a result of management’s analysis of certain qualitative factors impacting the reserve for credit losses and concern over the impact of the continued difficult economic conditions being experienced by our borrowers. This analysis included factors related primarily to portfolio risk and the impact of economic conditions on our portfolio.

The allowance for credit losses was $64.1 million, or 1.52%, of total loans outstanding at September 30, 2012, compared to $61.2 million, or 1.51%, at December 31, 2011 and $72.1 million, or 1.81%, at September 30, 2011. The decline from 1.81% at September 30, 2011, can be attributed to a $131.0 million, or 33%, decline in criticized loans, which encompasses the $68.0 million, or 42%, decrease in nonperforming loans. Nonperforming loans as a percentage of total loans decreased to 2.23% at September 30, 2012 from 2.76% at December 31, 2011 and 4.07% as of September 30, 2011. The allowance to nonperforming loan ratio was 68%, 62% and 45% as of September 30, 2012, December 31, 2011, and September 30, 2011, respectively. Improvement in these ratios contributed to the lower level of provision for credit losses for the nine-months ended September 30, 2012.

Net credit losses were $12.0 million in the nine-months ended September 30, 2012 compared to $29.0 million for the same period in 2011. The most significant credit losses recognized during the nine-months ended September 30, 2012, were a $1.4 million partial charge-off of a construction loan for a Florida condominium project and a $1.2 million partial charge-off of a commercial borrower in the shallow gas well business. Net credit losses during the nine-month period did not include any other significant individual charge-offs.

Noninterest Income (Continued)

Noninterest income, excluding net securities gains, gain on sale of assets and the joint venture termination fee, increased $7.2 million, or 19%, for the first nine months of 2012 compared to 2011. The most notable change in this total is the $6.5 million increase in the other income category. This increase is primarily the result of $1.1 million of income recognized in relation to the mark-to-market adjustment on interest rate derivatives during the first nine months of 2012 while a $5.6 million decline in income was recognized during the same period in 2011, as the result of an adverse mark-to-market adjustment related to credit deterioration for one commercial relationship. The increase in the mark-to-market adjustment recognized between the two periods is due to the change in the credit default curves over time as well as a change in counterparty credit risk related to the interest rate swaps. In addition, $1.0 million in swap fee income was earned during the nine-months ended September 30, 2012, while only $0.4 million was earned during the same period of 2011. The fees earned on these swaps are based on the notional value of the initiated contracts. In comparison, eleven swaps with a notional value of $111.5 million were entered into during 2012, while six swaps with a notional value of $32.6 million were entered into during the same period in 2011.

Total noninterest income increased $9.1 million in comparison to the nine-months ended September 30, 2011. The most significant changes in noninterest income, in addition to the aforementioned changes were a $2.0 million increase in gain on sale of assets and the receipt of a $1.9 million joint venture termination fee. The increase in gain on sale of assets is primarily the result of the sale of three loans transferred to held for sale in the fourth quarter of 2011. The sales of these loans were completed in March, April, and June of 2012 and resulted in a $2.9 million gain. The $1.9 million termination fee relates to the dissolution of a mortgage banking joint venture with another financial institution. As a result, the Company is exploring other strategic options related to the origination of residential mortgages. Offsetting these increases was a $2.0 million decrease in net security gains, primarily due to a $1.5 million gain recognized in 2011 from the sale of an equity security.

Noninterest Expense (Continued)

The 2012 increase in noninterest expense is largely attributable to expenses incurred in relation to salary and incentives paid to employees for developing customer relationships and originating loans as well as a $3.5 million operational loss.

During the third quarter of 2012, the Company experienced a $3.5 million operational loss due to an external fraud. The full amount of the loss has been recognized and an insurance claim, with up to a $0.5 million deductible, has been filed. The outcome of that claim has not been determined, therefore a receivable has not been recognized. In addition, various recovery strategies are currently being pursued.

Salary and employee benefits expense reflects an increase compared to the same period of 2011 primarily due to normal merit increases, the hiring of additional business development professionals and higher levels of employee incentives as a result of increased loan and deposit volumes. New loans originated during the nine-months ended September 30, 2012 totaled $1.0 billion compared to $626.7 million in the same period of 2011. The number of full-time equivalent employees decreased 67 positions from 1,479 at September 30, 2011 to 1,412 at September 30, 2012.

FDIC insurance expense decreased due to the favorable effects of changes made by the FDIC in its assessment methodology effective April 1, 2011.

Other expense increased primarily due to the unfunded commitment reserve recognized during the period. The unfunded commitment reserve is based on a calculation using outstanding commitments at period end, expected loss and expected usage. During the nine-months ended September 30, 2012, this expense was impacted by increased commitments and changes in expected utilization rates resulting in the recognition of $0.6 million in expense, while $0.6 million reversal of expense was recognized for the same period in 2011.

Income Tax

The provision for income taxes increased $6.4 million for the nine-months ended September 30, 2012, compared to the corresponding period in 2011. The higher provision for income taxes was primarily due to the increase in net income before tax of $18.6 million.

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 ended September 30, 2012 and 2011.

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 reduce our tax rate below the 35% statutory rate produced an annual effective tax rate of 26.0% and 20.1% for the nine-months ended September 30, 2012 and 2011, respectively.

As of September 30, 2012, our deferred tax assets totaled $62.2 million. Based on our evaluation as of September 30, 2012, 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 Ended September 30, 2012 Compared to Three-Months Ended September 30, 2011

Net Income

For the three-months ended September 30, 2012, First Commonwealth had net income of $9.8 million, or $0.09 per share, compared to net income of $8.3 million or $0.08 per share in the three-months ended September 30, 2011. The increase in net income is primarily the result of lower collection and repossession expense and other professional fees, the receipt of a joint venture termination fee and improvements in the mark-to-market adjustments on interest rate swaps. Partially offsetting these performance factors were an increase in salaries and employee benefits and operational losses.

Net Interest Income

Net interest income, on a fully taxable equivalent basis, was $47.4 million in the third quarter of 2012 compared to $48.8 million for the same period in 2011. Net interest margin, on a fully taxable equivalent basis, was 3.54% for the three-months ended September 30, 2012 compared to 3.81% for the three-months ended September 30, 2011. The taxable equivalent yield on interest-earning assets was 4.08% for the three-months ended September 30, 2012, a decrease of 53 basis points from the 4.61% for the same period in 2011.

Comparing the three months ended September 30, 2012 with the same period in 2011, changes in interest rates negatively impacted net interest income by $5.1 million. The lower yield on interest-earning assets adversely impacted net interest income by $7.4 million, while the decline in the cost of interest-bearing liabilities had a positive impact of $2.3 million. The cost of interest-bearing liabilities was 0.67% for the three months ended September 30, 2012, compared to 0.97% for the same period in 2011. 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 deposit and borrowed funds, disciplined pricing strategies, loan growth and increasing our investment volumes within established interest rate risk management guidelines.

While decreases in interest rates and yields compressed the interest rate margin, increases in average interest-earning assets and low cost average interest-bearing liabilities neutralized the effect on net interest income. Changes in the volumes of interest-earning assets and interest-bearing liabilities positively impacted net interest income by $4.0 million in the three-months ended September 30, 2012 compared to the same period in 2011. Higher levels of interest-earning assets resulted in an increase of $3.5 million in interest income, while volume changes primarily attributed to the mix of deposits reduced interest expense by $0.5 million

Positively affecting net interest income was a $113.3 million increase in average net free funds at September 30, 2012 as compared to September 30, 2011.

Provision for Credit Losses

The provision for credit losses is determined based on management’s estimates of the appropriate level of allowance for credit losses needed to absorb probable losses inherent in the loan 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 provision for credit losses for the three-months ended September 30, 2012 decreased in comparison to the three-months ended September 30, 2011, by $0.2 million or 3%. The provision for credit losses for the three months ended September 30, 2012 related to the real estate construction category is primarily a result of $18.0 million in loan growth, all within Pennsylvania. The commercial real estate provision for credit losses for this period can be attributed to a $3.3 million specific reserve required for an impaired loan.

Net credit losses were $4.3 million in the three-months ended September 30, 2012 compared to $10.0 million for the same period in 2011. Net credit losses during the three-month period included a $1.4 million charge-off on a construction loan for a Florida condominium project.

Noninterest Income (Continued)

Noninterest income, excluding net securities gains, gain on sale of assets and a joint venture termination fee, increased $5.0 million or 50% for the third quarter of 2012 compared to 2011. During the three-months ended September 30, 2012, $0.4 million in income was recognized as the result of credit mark-to-market adjustments on interest rate swaps, while a $5.1 million loss was recorded in the same period in 2011.

Total noninterest income increased $7.1 million primarily due to a joint venture termination fee received during the period as well as the previously mentioned fair market value adjustments made in relation to interest rate swaps.

Noninterest Expense

The following table presents the components of noninterest expense for the three-months ended September 30:

	2012		2011		$ Change			% Change

Total noninterest expense	$	44,765	$	41,121	$	3,644			9	%

The 2012 increase in noninterest expense is largely attributable to a $3.5 million increase in operational losses resulting from the previously mentioned external fraud.

Salary and employee benefits expense reflects an increase compared to the third quarter of 2011 primarily due to normal merit increases, the hiring of additional business development professionals and a higher level of employee incentives as a result of increased loan and deposit volumes. New loans originated during the third quarter of 2012 totaled $275.2 million compared to $250.6 million in the third quarter of 2011.

Collection and repossession expense decreased when comparing third quarter 2012 to the same period in 2011, primarily as a result of expenses recognized in the prior period to maintain one OREO property.

Loss on sale or write-down of assets increased due to the write-down of two foreclosed properties; one was written down approximately $0.2 million due to an updated appraisal and the other was written down approximately $0.1 million as a result of a pending sales agreement.

Income Tax

The provision for income taxes increased $1.3 million for the three-months ended September 30, 2012, compared to the corresponding period in 2011. The higher provision for income taxes was primarily due to the increase in net income before tax of $2.8 million.

The level of tax benefits that reduce our tax rate below the 35% statutory rate produced an annual effective tax rate of 24.2% and 18.2% for the three-months ended September 30, 2012 and 2011, 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 2012, liquidity provided from the $149.0 million increase in short-term borrowings, the net decrease of $12.0 million in investment securities and the sale of $13.4 million in loans provided funds to originate loans. 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, 2012, our maximum borrowing capacity under this program was $887.8 million and as of that date there was $89.0 million outstanding. We also participate in 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, 2012, our outstanding certificates of deposits from this program have an average weighted rate of 0.25% and an average original term of 73 days.

An additional source of liquidity is the FRB Borrower-in-Custody of Collateral program which enables us to pledge certain loans, not being used as collateral at the FHLB, as collateral for borrowings at the FRB. At September 30, 2012, the borrowing capacity under this program totaled $821.3 million and there were no amounts outstanding.

As of September 30, 2012, our maximum borrowing capacity at the FHLB of Pittsburgh was $1.3 billion and as of that date amounts used against this capacity included $382.3 million in outstanding borrowings and $26.0 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 and as of September 30, 2012 there are no amounts outstanding on this line. Additionally, we guarantee a $0.1 million ESOP loan.

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,		December 31,
	2012		2011
	(dollars in thousands)
Noninterest-bearing demand deposits	$	858,003	$	780,377
Interest-bearing demand deposits		97,834		95,945
Savings deposits		2,433,065		2,430,802
Time deposits		1,105,532		1,197,560
Total	$	4,494,434	$	4,504,684

During the first nine months of 2012, total deposits decreased $10.3 million due to an $87.9 million decline in interest bearing deposits, offset by an increase of $77.6 million in noninterest bearing deposits. The decrease in interest-bearing deposits can be attributed to a decline in time deposit balances which reflects a continued preference by customers to maintain non-maturity deposits as a result of the low interest rate environment. Partially offsetting the decline in time deposits were increases in interest-bearing demand deposits and savings deposits as a result of successful marketing promotions aimed at attracting new and retaining existing customers.

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 0.79 at September 30, 2012 and 0.76 at December 31, 2011. A ratio of less than one indicates a higher level of repricing liabilities over repricing assets over the next twelve months.

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. Rate sensitive assets to rate sensitive liabilities repricing in one year would indicate reduced net interest income in a rising interest rate scenario, and conversely, increased net interest income in a declining interest rate scenario.

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 versus if rates remained unchanged utilizing a flat balance sheet.

	Net interest income change (12 months)
	-200			-100			+100		+200
	(dollars in thousands)
September 30, 2012	$	(7,005	)	$	(4,126	)	$	46	$	1,356
December 31, 2011		(7,787	)		(3,997	)		704		2,324

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 decline in interest rate 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-month period ended September 30, 2012 and 2011, the cost of our interest-bearing liabilities averaged 0.73% and 1.04%, respectively, and the yield on our average interest-earning assets, on a fully taxable equivalent basis, averaged 4.22% and 4.67%, respectively.

The ALCO is responsible for the identification and management of interest rate risk exposure. As such, the ALCO continuously evaluates strategies to manage our exposure to interest rate fluctuations.

Asset/liability models require certain assumptions be made, such as prepayment rates on earning assets and pricing impact 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 to absorb 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. While allocations are made to specific loans and pools of loans, the total allowance is available for all loan losses.

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 half of 2012, nine relationships totaling $10.3 million were identified as troubled debt restructuring. Please refer to Note 10 “Loans and Allowance for Credit Losses” for additional information on troubled debt restructuring.

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 in 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 in nonaccrual status at 150 days past due. In the third quarter, the Company decided to place all loans 150 days or more past due on nonaccrual status. In periods prior to the third quarter of 2012, if a consumer loan was well secured and in the process of collection, it remained on accrual status, despite delinquency.

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.

The allowance for credit losses was $64.1 million at September 30, 2012 or 1.52% of total loans outstanding compared to 1.51% reported at December 31, 2011 and 1.81% at September 30, 2011. The stability in the September 30, 2012 ratio when compared to December 31, 2011 can be primarily attributable to a $0.3 million decrease in specific reserves resulting from a $4.8 million decrease in nonperforming loans, excluding loans held for sale and $170.7 million in loan growth, particularly in commercial loans. Complementing the decrease in nonaccrual loans is improvement in other credits measures. The level of criticized loans decreased as of September 30, 2012 when compared to December 31, 2011, by $23.0 million, or 8% and delinquency on accruing loans for the same period declined $10.2 million, or 29%.

The allowance for credit losses as a percentage of nonperforming loans was 68% as of September 30, 2012 compared to 62% at December 31, 2011 and 45% at September 30, 2011. 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 $12.9 million related to nonperforming loans covering 14% of the total nonperforming balance. 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, 2012.

In addition, a $2.2 million loan to a retail development company in western Pennsylvania paid off during the first quarter.

Capital Resources

At September 30, 2012, shareholders’ equity was $773.9 million, an increase of $15.3 million from December 31, 2011. The increase was primarily the result of $33.2 million net income offset by $13.6 million of dividends paid to shareholders. Additionally, other comprehensive income increased $3.0 million due to changes in the fair value of available for sale investments and unearned ESOP shares decreased $1.5 million. Cash dividends declared per common share were $0.13 and $0.09 for the nine-months ended September 30, 2012 and 2011, 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

Capital Resources (Continued)

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.

Quantitative measures established by regulation 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, 2012, First Commonwealth and its banking subsidiary met all capital adequacy requirements to which they are subject.

The table below presents First Commonwealth’s capital position at September 30, 2012.

ITEM 3. Quantitative and Qualitative Disclosures About Market Risk

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

ITEM 4. Controls and Procedures

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

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

	For a discussion of certain risk factors affecting the Company, see Part I, Item 1A: Risk Factors of the Company’s Annual Report on Form 10-K for the year ended December 31, 2011, and Forward-Looking Statements on page 43 of this Form 10-Q. There were no material changes to the risk factors described above other than the following:
	Acts of cyber-crime may compromise client and company information, disrupt access to our systems or result in loss of client or company assets.
	Our business is dependent upon the availability of technology, the Internet and telecommunication systems to enable financial transactions by clients, record and monitor transactions and transmit and receive data to and from clients and third parties. Information security risks have increased significantly due to the use of online, telephone and mobile banking channels by clients and the increased sophistication and activities of organized crime, hackers, terrorists and other external parties. Our technologies, systems, networks and our clients’ devices have been subject to, and are likely to continue to be the target of, cyber-attacks, computer viruses, malicious code, phishing attacks or information security breaches that could result in the unauthorized release, gathering, monitoring, misuse, loss or destruction of our or our clients’ confidential, proprietary and other information, the theft of client assets through fraudulent transactions or disruption of our or our clients’ or other third parties’ business operations.
	During the quarter ending September 30, 2012, we incurred a $3.5 million charge in connection with fraudulent wire transfers involving the breach of a commercial client’s computer system to gain access to our online banking system. There was no breach of First Commonwealth’s systems, however, following this incident, we have enhanced our monitoring and security procedures to help prevent and mitigate the risk of fraudulent transfers. However, there can be no assurance that we will not incur fraud losses in the future.

Basis of Presentation

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 ended September 30, 2012 are not necessarily indicative of the results that may be expected for the full year of 2012. These interim financial statements should be read in conjunction with First Commonwealth’s 2011 Annual Report on Form 10-K which is available on First Commonwealth’s website at http://www.fcbanking.com.

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.

Goodwill

Goodwill

Note 14 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 2011-08 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, 2012 and December 31, 2011 was $159.9 million. No impairment charges on goodwill or other intangible assets were incurred in 2012 or 2011.

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, 2012 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 2 goodwill impairment test completed as of December 31, 2011 as well as macroeconomic factors, industry and market considerations, the company’s overall financial performance, and other company specific events occurring during the first nine months of 2012.

As of September 30, 2012, 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.

Impairment of Investment Securities

9 Months Ended

Sep. 30, 2012

Impairment of Investment Securities

Note 9 Impairment of Investment Securities

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 ended September 30, 2012 and 2011, no other-than-temporary impairment charges were recognized. For the nine-months ended September 30, 2012, $1.5 million in non-credit related gains on our trust preferred collateralized debt obligations that were determined to be impaired in previous periods was recorded in OCI. For the same period in 2011, $0.2 million in non-credit related losses for the same pool of securities was recorded in OCI. All of the securities for which other-than-temporary impairment was recorded were classified as available for sale securities.

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.

In the Condensed Consolidated Statements of Income, the “Changes in fair value on impaired securities” line represents the change in fair value of securities impaired in the current or previous periods. The change in fair value includes both non-credit and credit related gains or losses. Credit related losses occur when the entire amortized cost of the security will not be recovered. The “Non-credit related (gains) losses on securities not expected to be sold (recognized in other comprehensive income)” line represents the gains and losses on the securities resulting from factors other than credit. The non-credit related gain or loss is disclosed in the Condensed Consolidated Statements of Income and recognized through other comprehensive income. The “Net impairment losses” line represents the credit related losses recognized in total noninterest income for the related period.

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 12, “Fair Values of Assets and Liabilities,” for additional information.

The following table presents the gross unrealized losses and estimated fair values at September 30, 2012 by investment category and time frame for which securities have been in a continuous unrealized loss position:

(a) Gross unrealized losses related to these types of securities are less than $1 thousand.

At September 30, 2012, pooled trust preferred collateralized debt obligations accounted for almost all of the unrealized losses, while fixed income securities issued by U.S. Government-sponsored enterprises comprised less than one percent of total unrealized losses. There were no equity securities in an unrealized loss position at September 30, 2012.

As of September 30, 2012, our corporate securities had an amortized cost and an estimated fair value of $10.8 million and $11.1 million, respectively, and were comprised of single issue trust preferred securities issued primarily by money center and large regional banks. As of December 31, 2011, the same portion of the portfolio had an amortized cost of $11.8 million and an estimated fair value of $11.4 million. There were no corporate securities in an unrealized loss position as of September 30, 2012, while as of December 31, 2011, there were $0.6 million in unrealized losses related to these investments. When unrealized losses exist, management reviews each of the issuer’s asset quality, earnings trend 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.

The following table presents the gross unrealized losses and estimated fair values at December 31, 2011 by investment category and time frame for which securities have been in a continuous unrealized loss position:

(a) Gross unrealized losses related to these types of securities are less than $1 thousand.

As of September 30, 2012, the book value of our pooled trust preferred collateralized debt obligations totaled $52.7 million with an estimated fair value of $23.1 million, which includes securities comprised of 339 banks and other financial institutions. Two of our pooled securities are senior tranches and the remainders are mezzanine tranches, three of which have no senior class remaining in the issue. Two of the pooled issues, representing $2.9 million of the $52.7 million book value, remain above 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, 2012, after taking into account management’s best estimates of future interest deferrals and defaults, six of our securities had no excess subordination in the tranches we own and seven of our securities had excess subordination which ranged from 10% to 566% of the current performing collateral.

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

On a quarterly basis we evaluate our debt securities for other-than-temporary impairment. During the nine-months ended September 30, 2012 and 2011, 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, 2012. 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. For collateral issued by financial institutions with over $15 billion in asset size, we consider the alternative cost of funding and if that rate is less than the current rate being paid, we incorporate a prepayment in our estimate of future cash flows. The prepayment rates used are 20% in years 2 and 3 and a 2% prepayment rate thereafter. 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 339 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, 2012, 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 allows 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, 2012, indicates that no credit related other-than-temporary impairment has occurred on our pooled trust preferred securities during the nine-months ended September 30, 2012. Based upon the analysis performed by management, it is probable that six 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 17 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, 2012 indicates it is probable that we will collect all contractual principal and interest payments.

During 2008, 2009 and 2010, other-than-temporary impairment charges were recognized on all of our pooled trust preferred securities, except for PreTSL I, PreTSL IV and MMCap I-Senior. Our cash flow analysis as of September 30, 2012, 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 our current book value being below the present value of estimated future principal and interest payments. The excess for each bond of the present value of future cash flows over our current book value ranges from 14% to 144% and will be recognized as an adjustment to yield over the remaining life of these securities. During the three- and nine-months ended September 30, 2012, $0.4 million and $0.9 million, respectively, of the excess was recognized as an adjustment to yield on these securities.

The following 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 third quarter of 2012 and 2011, 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, 2012 and 2011, there are no equity securities in an unrealized loss position.

Loans and Allowance for Credit Losses

Note 10 Loans and Allowance for Credit Losses

The following table provides outstanding balances related to each of our loan types:

	September  30, 2012		December  31, 2011
	(dollars in thousands)
Commercial, financial, agricultural and other	$	1,087,019	$	996,739
Real estate construction		95,425		76,564
Residential real estate		1,228,328		1,137,059
Commercial real estate		1,217,249		1,267,432
Loans to individuals		586,278		565,849
Total loans and leases net of unearned income		4,214,299	$	4,043,643

During the nine-months ended September 30, 2012, all loan categories, except commercial real estate, increased with total loans increasing $170.7 million or 4% compared to balances outstanding at December 31, 2011. A majority of the loan growth was recognized in the residential real estate portfolio as a result of seasonal demand and an ongoing loan promotion. Increases in commercial, financial, agricultural and other portfolio can be attributed to growth in direct middle market lending and syndications in Pennsylvania and contiguous states, while loans to individuals increased due to growth in home equity installment loans and indirect auto lending.

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. Movements 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

Credit quality measures at September 30, 2012 compared to December 31, 2011 indicate a decrease in criticized loans, or loans designated OAEM, substandard or doubtful, of $23.0 million, or 8%, a decrease in delinquency 30 days and over on accruing loans of $10.2 million, or 29%, and an $8.3 million increase in nonaccrual loans, excluding loans held-for-sale.

Charge-offs for the nine-months ended September 30, 2012 totaled $13.4 million compared to $30.1 million for the nine-months ended September 30, 2011. The most significant charge-offs during the nine-months ended September 30, 2012 were a $1.4 million charge taken on a Florida real estate construction loan with a remaining balance of $4.3 million and a $1.2 million charge taken on a $2.0 million commercial loan relationship. During the nine-months ended September 30, 2011, the most significant charge-off totaled $5.2 million and related to a central Pennsylvania development loan relationship. Other significant charge-offs during the nine-month period in 2011 totaled $10.8 million and related to six construction loan projects located in Florida, Nevada, Ohio and western and central Pennsylvania.

Criticized loans totaled $269.0 million at September 30, 2012 and represented 6% of the loan portfolio. This represents a $23.0 million decrease compared with the portfolio as of December 31, 2011. These loans have been evaluated when determining the appropriateness of the allowance for credit losses, which we believe is adequate at this time. 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.

The credit quality of our loan portfolio represents significant risk to our earnings, capital, regulatory agency relationships and shareholder returns. First Commonwealth devotes a substantial amount of resources to 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.

Risk factors associated with commercial real estate and construction related loans are monitored closely since this is an area that represents a significant portion of the loan portfolio and has experienced the most stress during the economic downturn.

In addition, during the first nine months of 2012, nine relationships consisting of fifteen loans, were classified as troubled debt restructuring. These loans increased the nonperforming loan balance by $10.3 million with a $3.2 million increase in specific reserves.

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. In periods prior to the third quarter of 2012, if a consumer loan was well secured and in the process of collection, it remained on accrual status, as delinquency was not a factor in moving it to nonaccrual status.

Nonaccrual Loans

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, excluding loans held for sale, decreased $4.9 million to $93.9 million at September 30, 2012 compared to $98.8 million at December 31, 2011. Contributing to this decrease was an $11.3 million loan to a waste management company which was paid off in the first quarter and a $10.3 million loan to an information technology firm which was returned to accrual status in the second quarter. The most significant loans placed into nonperforming status during the first nine months of 2012 included $6.7 million to a western Pennsylvania in-patient facility, $4.9 million for a commercial real estate loan to a nonprofit institution, $2.5 million to a manufacturer of medical equipment and $2.8 million to a western Pennsylvania construction firm. During the third quarter of 2012, a $0.9 million payment was received on the aforementioned $4.9 million loan to a nonprofit, providing for a current balance on this loan of $3.9 million. Also impacting the balance of nonperforming loans for the period was the movement to nonaccrual status of $4.8 million in consumer loans which were 150 days or more past due. Beginning in the third quarter of 2012, consumer loans are moved to nonaccrual status once they reach 150 days past due, however, in prior periods, these loans were not placed in nonaccrual status if they were well secured and in the process of collection. The majority of the consumer loans moved to nonaccrual status in the third quarter, or $4.7 million of the $4.8 million, were residential real estate loans.

The specific allowance for nonperforming loans decreased by $0.3 million at September 30, 2012 compared to December 31, 2011, primarily due to the decrease in balances. Unfunded commitments related to nonperforming loans were $5.1 million at September 30, 2012 and after consideration of available collateral related to these commitments, an off balance sheet reserve of $44 thousand was established.

Loans held for sale totaled $13.4 million at December 31, 2011 and the entire balance represented nonperforming loans. As of September 30, 2012, the sale of all of these loans had been completed and provided for a $2.9 million gain. While these loans were considered to be nonperforming, they were not taken into consideration when determining the allowance for credit losses as they were carried at the lower of cost or fair value.

Significant nonaccrual loans as of September 30, 2012, include the following;

• $19.3 million, the remaining portion of a $44.1 million unsecured loan to a western Pennsylvania real estate developer. This loan was originated in the second quarter of 2004 and was placed in nonaccrual status in the fourth quarter of 2009. A settlement plan with the borrower and three other lenders was reached in the fourth quarter of 2010 and resulted in an $8.0 million principal payment and a $15.4 million partial charge-off.

• $16.0 million commercial real estate loan for a real estate developer in eastern Pennsylvania. This loan was originated in the third quarter of 2007 and restructured in the fourth quarter of 2011which resulted in a charge-off of $4.2 million. The most recent appraisal for the real estate collateral was completed in the third quarter of 2011.

• $6.7 million commercial real estate loan to an in-patient facility in western Pennsylvania. This loan was originated in the fourth quarter of 2008 and placed in nonaccrual status in September 2012. Because this loan was not previously classified, the most recent appraisal for the real estate collateral was at loan origination. Therefore, the collateral valuation and resulting shortfall on this loan were determined using a real estate common level ratio.

• $4.3 million, the remaining portion of a $20.8 million construction loan for a Florida condominium project. This loan was originated in the second quarter of 2007. Charge-offs of $16.5 million have been recorded on this loan. The most recent appraisal for the real estate collateral was completed in the second quarter of 2012.

• $3.9 million real estate secured loan to a western Pennsylvania nonprofit corporation. This loan was originated in the fourth quarter of 2008 and placed in nonaccrual status in the second quarter of 2012. The most recent appraisals for the various real estate collateral were completed in the fourth quarter of 2011 and the first quarter of 2012.

The following tables include the recorded investment and unpaid principal balance for impaired loans with the associated allowance amount, if applicable, as of September 30, 2012 and December 31, 2011. Also presented are the average recorded investment in impaired loans and the related amount of interest recognized while the loan was considered impaired. Average balances are calculated based on month-end balances of the loans of the period reported.

Impaired Loans (Continued)

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 financial difficulties experienced by the borrower, who could not obtain comparable terms from alternate financing sources.

The following table provides detail as to the total troubled debt restructured loans and total commitments outstanding on troubled debt restructured loans:

At September 30, 2012, troubled debt restructured loans on accruing status decreased $13.1 million compared to December 31, 2011 and commitments related to troubled debt restructured loans decreased $11.3 million for the same period. These decreases are primarily a result of the payoff of an $11.3 million loan to a waste management company in Pennsylvania as a result of the sale of the business. In addition, a $2.2 million loan to a retail development company in western Pennsylvania paid off during the first quarter. During 2012 and 2011 the changes in loan balances between the pre-modification balance and the post-modification balance are due to customer payments.

Variable Interest Entities

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:

Commitments and Contingent Liabilities

Commitments and Contingent Liabilities

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,		December 31,
	2012		2011
	(dollars in thousands)
Financial instruments whose contract amounts represent credit risk:
Commitments to extend credit	$	1,515,221	$	1,495,009
Financial standby letters of credit		48,864		53,689
Performance standby letters of credit		77,795		76,371
Commercial letters of credit		1,047		1,297

The current notional amounts outstanding as of September 30, 2012 include financial standby letters of credit of $0.3 million, performance standby letters of credit of $19.5 million, and commercial letters of credit $0.4 million issued during the first nine months of 2012. A liability of $0.2 million and $0.1 million has been recorded as of September 30, 2012 and December 31, 2011, respectively, 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 in these commitments resulted in the recording of a liability of $2.1 million as of September 30, 2012 and $1.5 million as of December 31, 2011. 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

McGrogan v. First Commonwealth Bank is a class action that was filed 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 asserts that the Bank committed fraud, breached its modified contract with the class members, and violated the Pennsylvania Unfair Trade Practice and Consumer Protection Law 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. At that time, there were 237 account holders with an average age of 64, and the aggregate balances in the IRA Market Rate Savings accounts totaled approximately $11.5 million. Plaintiffs seek 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. On July 27, 2011, 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 is 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 dismissing 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. The Plaintiffs have filed an appeal with the Pennsylvania Superior Court.

Other matters

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 or financial position of First Commonwealth or its subsidiaries.

Other Investments

Note 8 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. 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, 2012 and December 31, 2011, our FHLB stock totaled $32.5 million and $39.8 million, respectively and is included in “Other investments” on the Condensed Consolidated Statements of Financial Condition.

During 2012 and 2011, the FHLB repurchased excess stock from its members by repurchasing the lessor of 5% of the members’ total capital stock outstanding or its total excess capital stock. As a result, during the nine-months ended September 30, 2012 and 2011, stock repurchases occurred in the amounts of $7.3 million and $7.0 million, respectively. The FHLB repurchased stock and paid dividends in each quarter of 2012, however, decisions regarding any future repurchase of excess capital stock and dividend payments will be made by the FHLB on a quarterly basis. Management reviewed the FHLB’s Form 10-Q for the period ended June 30, 2012 filed with the SEC on August 8, 2012.

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 ended September 30, 2012. Our evaluation of the factors described above in future periods could result in the recognition of impairment charges on FHLB stock.

Note 13 Derivatives

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 enters into with customers to allow customers to convert variable rate loans to a fixed rate. First Commonwealth pays interest to the customer at a floating rate on the notional amount and receives interest from the customer at a fixed rate for the same notional amount. At the same time the interest rate swap is entered into with the customer, an offsetting interest rate swap is entered into with another financial institution. First Commonwealth pays the other financial institution interest at the same fixed rate on the same notional amount as the swap entered into with the customer, and receives interest from the financial institution for the same floating rate on the same notional amount. The changes in the fair value of the swaps offset each other, except for the credit risk of the counterparties, which is determined by taking into consideration the risk rating, probability of default and loss of given default for all counterparties.

We have twelve 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.

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

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:

	September 30, 2012			December 31, 2011
	(dollars in thousands)

Risk participation agreements		86,980			128,098

The table below presents the amount representing the change in the fair value of derivative assets and derivative liabilities attributable to credit risk included in other income on the Condensed Consolidated Statements of Income:

	(dollars in thousands)
Non-hedging interest rate derivatives:
Increase (decrease) in other income	$	375	$	(5,108	)	$	1,126	$	(5,643	)

During 2012, total credit risk income of $1.3 million was recognized, offset by $0.2 million in expense related to three interest rate swaps that were downgraded during the third quarter to a below investment grade rating. As a result of the deterioration of credit risk related to the counterparty, a larger mark-to-market adjustment was recorded. The fair value of our derivatives is included in a table in Note 12 “Fair Values of Assets and Liabilities,” in the line items other assets and other liabilities.

Fair Values of Assets and Liabilities

Fair Values of Assets and Liabilities

Note 12 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, certain corporate securities, FHLB stock, interest rate derivatives that include 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 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 fair value is based on its par value. Additional information on FHLB stock is provided in Note 8, “Other Investments.”

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. First Commonwealth values its interest rate swap 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 13, “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 2012, we have not realized any losses due to a counterparty’s inability to pay any net uncollateralized position.

The 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, loans held for sale and 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 was more appropriate to determine 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 9, “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.

Loans held for sale are carried at the lower of cost or fair value with the fair value being the expected sales price of the loan. The estimated fair value of the loans held for sale was determined by calculating the discounted expected future cash flows of the loan. The discount rate applied to the future cash flows was determined based on a risk based expected return and capital structure of potential buyers. If a sales agreement has been executed, the fair value is equal to the sales price.

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 2012, we have not realized any losses due to a counterparty’s inability to pay any net uncollateralized position. However, as the result of deterioration in the counterparties (loan customers) credit quality for certain interest rate derivatives, future amounts previously believed to be collectible under the terms of the interest rate derivative have now been deemed to be uncollectible.

In accordance with ASU 2011-04, 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	$23,051	Discounted Cash Flow	Probability of default	0% -100% (21.73%)
			Prepayment rates	0% -100% (13.44%)
			Discount rates	6.75% - 20%(a)
Other Investments	1,420	Par Value	N/A	N/A
Interest Rate Swap	0	Option model	Counterparty credit risk	15.08% - 17.63%(b)
Impaired Loans	15,755(c)	Discounted Cash Flow	Discount rate	8.42% - 8.83%
Other Real Estate Owned	338	Internal Valuation	N/A	N/A

(a) incorporates premium related 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.

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.

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 ended September 30, 2012, there were no transfers between fair value Levels 1 and 2. However, $0.5 million of interest rate swaps were transferred into Level 3 from Level 2 due to deterioration of the counterparty’s credit risk. Because the credit quality of the underlying counterparty declined below investment grade, the swaps were valued utilizing more than interest rate yield curves. During the second quarter of 2011, $12.0 million of corporate securities were transferred from Level 3 to Level 2. Corporate securities were transferred from Level 3 to Level 2 based on increased frequency in the volume of observable trades. Fair values on these securities at September 30, 2011 were determined based on market data, including trade and bid prices. During the third quarter of 2011, $4.5 million of interest rate swaps were transferred into Level 3 from Level 2 also due to deterioration of the counterparty’s credit risk. 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, 2012 and 2011.

For the three-month periods ended September 30, changes in Level 3 assets and liabilities measured at fair value on a recurring basis are summarized as follows:

For the three-months ended September 30, 2012, there were no transfers of securities between Levels 1, 2 or 3. During the third quarter of 2011, $4.5 million of interest rate swaps were transferred into Level 3 from Level 2 due to deterioration of the counterparty’s credit risk. 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, 2012 and 2011.

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

	September 30, 2012

The following 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,
	2012			2011			2012			2011
	(dollars in thousands)

Other real estate owned		(366	)		(88	)		(523	)		(4,185	)
Total losses	$	(4,256	)	$	(7,236	)	$	(7,875	)	$	(32,260	)

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. 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.

The fair value for other real estate owned is determined by either an independent market based appraisal less estimated costs to sell or an executed sales agreement and is classified as Level 2. Other real estate owned has a book cost of $16.0 million as of September 30, 2012 and consisted primarily of a manufacturing plant in northern Pennsylvania, residential real estate in eastern Pennsylvania and a commercial real estate property in eastern Pennsylvania. During the first quarter of 2012, the sale of an office building in western Pennsylvania which was previously in OREO for $6.8 million was completed and resulted in a $0.3 million loss at the time of sale. During the third quarter of 2012, a real estate property located in central Pennsylvania which was in OREO for $1.2 million was sold and resulted in a $0.6 million gain. 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 14, “Goodwill.” There were no other assets or liabilities measured at fair value on a non-recurring basis during the nine-months ended September 30, 2012.

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 held for sale: The fair value of loans held for sale is estimated utilizing a present value of future discounted cash flows of the loan utilizing a risk based expected return to discount the value unless a sales agreement has been executed, in which case the sales price would equal 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 $0.2 million and $0.1 million at September 30, 2012 and December 31, 2011, respectively. See Note 6, “Commitments and Contingent Liabilities,” for additional information.

Deposit liabilities: Management estimates that the fair value of deposits is based on a market valuation of similar deposits. 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 estimated incremental borrowing rate for similar types of borrowing arrangements.

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