Summary of Significant Accounting Policies

Nature of Operations and Basis of Presentation

Metro Bancorp, Inc. (Metro or the Company) is a Pennsylvania business corporation, which is registered as a bank holding company under the Bank Holding Company Act of 1956, as amended. The Company was incorporated on April 23, 1999 and became an active bank holding company on July 1, 1999. The Company is a one-bank holding company headquartered in Harrisburg, Pennsylvania and provides full banking services through its subsidiary, Metro Bank (the Bank). The Company is subject to regulation by the Federal Reserve Bank (FRB). Metro Bank is the Company's operating entity and is headquartered in Lemoyne, Pennsylvania. The Bank became a state-chartered bank on November 7, 2008, following approval by the Pennsylvania Department of Banking of the Bank's application to convert from a national bank charter to a state bank charter. As a Pennsylvania state-chartered bank, Metro Bank is supervised jointly by the Pennsylvania Department of Banking and Securities and the Federal Deposit Insurance Corporation (FDIC). The Bank is a financial services retailer with stores in the counties of Berks, Cumberland, Dauphin, Lancaster, Lebanon and York, Pennsylvania. The Bank had a total of 33 stores at December 31, 2014 and opened one additional store in January 2015 in Lancaster County.

The consolidated financial statements presented include the accounts of Metro Bancorp, Inc. and its wholly-owned subsidiary Metro Bank. All material intercompany transactions have been eliminated. Events occurring subsequent to the date of the balance sheet have been evaluated for potential recognition or disclosure in the consolidated financial statements.

Use of Estimates

The consolidated financial statements are prepared in conformity with generally accepted accounting principles (GAAP). Accounting principles generally accepted in the United States of America require management to make estimates and assumptions that affect reported amounts of assets and liabilities and require disclosure of contingent assets and liabilities. In the opinion of management, all adjustments considered necessary for fair presentation have been included and are of a normal, recurring nature. Actual results could differ from these estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses (allowance or ALL), impaired loans, the valuation of foreclosed assets, the valuation of securities available for sale, the valuation of deferred tax assets, the determination of other-than-temporary impairment (OTTI) on the Company's investment securities portfolio and other fair value measurements.

Other Comprehensive Income

Accounting principles generally require that recognized revenue, expenses, gains and losses be included in net income. Although certain changes in assets and liabilities, such as unrealized gains and losses on available for sale (AFS) securities, are reported as a separate component of the equity section of the balance sheet, such items, along with net income are components of comprehensive income. In addition to net income, the Company's total comprehensive income includes net unrealized gains (losses) on AFS securities and noncredit-related other-than-temporary impairment charges on debt securities. These items are presented net of tax in the Statements of Comprehensive Income (Loss).

Significant Group Concentrations of Credit Risk

Most of the Company's activities are with customers located within South Central Pennsylvania. Notes 4 and 6 discuss the types of lending that the Company engages in as well as loan concentrations. The Company does not have any significant concentrations to any one borrower or related borrowers. The types of securities the Company invests in is discussed in Note 3.

Securities

Securities classified as held to maturity are those debt securities that the Company has both the intent and ability to hold to maturity regardless of changes in market conditions, liquidity needs or general economic conditions. These securities are carried at cost adjusted for amortization of premium and accretion of discount, computed by the interest method over the estimated average life of amortizing securities and to either the maturity or expected call date of nonamortizing securities.

Securities classified as available for sale are those debt securities that the Company intends to hold for an indefinite period of time, but not necessarily to maturity. Any decision to sell a security classified as available for sale would be based on various factors, including significant movements in interest rates, changes in the maturity mix of the Company's assets and liabilities, liquidity needs, regulatory capital considerations and other similar factors. Securities available for sale are carried at fair value. Unrealized gains or losses are reported in other comprehensive income, net of the related deferred tax effect. Realized gains or losses, determined on the basis of the cost of the specific securities sold, are included in earnings. Premiums and discounts are recognized in interest income using the interest method over the estimated average life of amortizing securities and to either the maturity or expected call date of nonamortizing securities. Management determines the appropriate classification of debt securities at the time of purchase.

Other-Than-Temporary Impairment

Beginning in 2013, the Company performed its own independent credit review of all nongovernment and nongovernmental agency securities when determining whether a debt security is other-than-temporarily impaired. This includes a quarterly review of all existing debt securities as well as a pre-purchase analysis for new securities purchased. This review/analysis considers, but does not rely upon, ratings by a nationally recognized statistical ratings organization. Management also assesses whether we have the intent to sell the security or it is more likely than not that we will be required to sell the security prior to its anticipated recovery.

Prior to 2013, the Company followed the fair value measurement guidance which clarified the interaction of the factors that should be considered when determining whether a debt security was other-than-temporarily impaired. For debt securities, management assessed whether we had the intent to sell the security or it was more likely than not that we would be required to sell the security prior to its anticipated recovery. The Company forecasted recovery of the value of the security through either cash flows or market price.

In instances when a determination is made that an OTTI exists but we do not intend to sell the debt security and it is not likely that we will be required to sell the debt security prior to its anticipated recovery, the OTTI is separated into (a) the amount of the total OTTI related to a decrease in cash flows expected to be collected from the debt security (the credit loss) and (b) the amount related to all other factors. The amount of the OTTI related to the credit loss is recognized in earnings and the amount of the OTTI related to all other factors is recognized in other comprehensive income.

Loans Held for Sale

Loans held for sale are comprised of student loans, selected residential mortgage loans and the guaranteed portion of certain small business administration (SBA) loans the Company originates with the intention of selling in the future. Held for sale loans are carried at the lower of cost or estimated fair value, calculated in the aggregate. At the present time, the majority of the Company's residential loans are originated with the intent to sell to the secondary market unless a loan is nonconforming to the secondary market standards or if we agree not to sell the loan due to a customer's request. The residential mortgage loans that are designated as held for sale are sold to other financial institutions in correspondent relationships. The sale of these loans takes place typically within 30 days of funding. The Company does not retain the servicing on its residential mortgage loans or its student loans. The Company retains servicing on SBA loans sold, which is not material at December 31, 2014.

The Company holds other SBA loans in the loan receivable portfolio unless or until the Company's management determines a sale of those certain loans is appropriate. At the time such a decision is made, those SBA loans are moved from the loans receivable portfolio to the loans held for sale portfolio and recorded at the lower of cost or fair value. During 2014, SBA loans with a carrying amount of $9.3 million previously classified as loans receivable were transferred to the loans held for sale portfolio and subsequently sold at a total gain of $310,000. During 2014, the Company began originating certain types of SBA loans with the intent to sell the guaranteed portion of each of these loans. The Company received proceeds of $2.3 million on sales of such loans in 2014 and recognized a gain of $134,000 on those sales. There were no SBA loan sales in 2013 or 2012.

Total loans held for sale were $5.0 million and $6.2 million at December 31, 2014 and 2013, respectively. At December 31, 2014, loans held for sale were comprised of $2.6 million of residential mortgages and $2.4 million of student loans as compared to $3.1 million of student loans and $3.1 million of residential mortgages at December 31, 2013. There were no SBA loans held for sale at December 31, 2014 and 2013, respectively.

Loans Receivable

Loans receivable that management has the intent and ability to hold for the foreseeable future, or until maturity or payoff, are stated at their outstanding unpaid principal balances, net of an ALL and any deferred fees and costs. Interest income is accrued on the unpaid principal balance. Loan origination fees and costs are deferred and recognized as an adjustment of the yield (interest income) of the related loans. The Company is generally amortizing these amounts over the contractual life of the loan.

A loan is considered past due or delinquent if payment is not received on or before the due date. The accrual of interest is generally discontinued when the contractual payment of principal or interest has become 90 days past due or management has serious doubts about further collectibility of principal or interest, even though the loan may be currently performing. A loan may remain on accrual status if it is in the process of collection and is either guaranteed or well secured. When a loan is placed on nonaccrual status, unpaid interest credited to income in the current year is reversed and unpaid interest accrued in prior years is charged against the ALL. Interest received on nonaccrual loans generally is either applied against principal or reported as interest income, according to management's judgment as to the collectibility of principal. If a loan is substandard and accruing, interest is recognized as accrued. Generally, loans are restored to accrual status when the obligation is brought current, has performed in accordance with the contractual terms for a reasonable period of time and the ultimate collectibility of the total contractual principal and interest is no longer in doubt.

Allowance for Loan Losses

The ALL is established through provisions for incurred loan losses charged against income. Loans, or portions thereof, deemed to be uncollectible are charged against the ALL and subsequent recoveries, if any, are credited to the allowance. The evaluation is inherently subjective as it requires material estimates that can change significantly as more information becomes available. Loans are evaluated for impairment once the loan has been internally risk rated substandard or lower or has been classified as a troubled debt restructuring (TDR).

The allowance consists of specific and general components. The specific component relates to loans that are classified as impaired. For such loans, an allowance is based on an analysis of the discounted cash flows, net collateral value or observable market price of the impaired loan, relative to the carrying value of the loan. The general component covers nonclassified loans and is based on historical loss experience adjusted for qualitative factors and includes an unallocated component. These qualitative factors represent a portion of the allowance established for losses inherent in the loan portfolio, which have not been identified by the quantitative processes. This determination inherently involves a higher degree of subjectivity and considers risk factors that may not have yet manifested themselves in historical loss experience. These factors include:

•

Changes in lending policies and procedures, including changes in underwriting standards;

•

Changes in levels and trends of collection, charge-off and recovery practices;

•

Changes in the volume and severity of past due loans, the volume of nonaccrual loans and the volume and severity of adversely classified or graded loans;

•

Material changes in the mix, volume or duration of the portfolio;

•

Changes in the value of underlying collateral for collateral-dependent loans;

•

Changes in the quality of our loan review system;

•

Changes in the experience, ability and depth of lending management and other relevant staff;

•

The existence and effect of any concentrations of credit and changes in the level of such concentrations; and

•

Changes in international, national, regional and local economic and business conditions and developments that affect the collectibility of the portfolio, including the condition of various market segments and the effect of other external factors such as competition and legal and regulatory requirements on the level of estimated credit losses in our existing portfolio.

The ALL is maintained at a level considered adequate to provide for losses that can be reasonably anticipated. Management's periodic evaluation of the adequacy of the allowance is based on the Company's past loan loss experience, known and inherent risks in the portfolio, adverse situations that may affect the borrower's ability to repay, the estimated value of any underlying collateral, composition of the loan portfolio, current economic conditions and other relevant factors.

A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining impairment include the borrower's ability to pay, payment status, borrower's financial condition, market conditions for the borrowers' type of industry and other relevant factors. Loans that experience insignificant payment delays generally are not classified as impaired. Management determines the significance of payment delays on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay and the borrower's prior payment record. Impairment is measured on a loan-by-loan basis for commercial loans by either the present value of expected future cash flows discounted at the loan's effective interest rate, the loan's obtainable market price or the fair value of the collateral, net of expected selling costs, if the loan is collateral dependent.

All nonaccrual loans are deemed impaired and evaluated individually to determine whether a charge-off is necessary.

Restricted Investments in Bank Stock

Restricted investments in bank stock (restricted stock) consists of stock of the Federal Home Loan Bank (FHLB) of Pittsburgh and the Atlantic Community Bankers Bank (ACBB). Federal law requires a member institution of the FHLB system to hold stock of its district FHLB according to a predetermined formula. At December 31, 2014, the Company held $15.2 million of FHLB stock. Of this amount, $1.5 million was required for membership and $13.7 million was required to cover the Company's borrowing level at the FHLB. During 2013 the FHLB lifted the repurchase suspension that had been in place since December of 2008. The Company also owned $65,000 of ACBB stock at December 31, 2014. The investments are carried at cost and periodically evaluated by management for impairment based on an assessment of the ultimate recoverability of the cost rather than by recognizing temporary declines in value. Regarding FHLB restricted stock, the determination of whether a decline in value affects the ultimate recoverability of the cost is influenced by criteria such as (1) the significance of the decline in net assets of the FHLB as compared to the capital stock amount for the FHLB and the length of time this situation has persisted, (2) commitments by the FHLB to make payments required by law or regulation and the level of such payments in relation to the operating performance of the FHLB, (3) the impact of legislative and regulatory changes on institutions and, accordingly, on the customer base of the FHLB and (4) the liquidity position of the FHLB. Management believes no impairment charge was necessary related to its investments in restricted stock as of December 31, 2014.

Premises and Equipment

Premises and equipment are carried at cost less accumulated depreciation and amortization. Depreciation is charged to operations over the estimated useful lives of the respective assets. Leasehold improvements are amortized over the terms of the respective leases or the estimated useful lives of the improvements, whichever is shorter. Depreciation and amortization are determined on the straight-line method for financial reporting purposes and accelerated methods for income tax purposes.

Foreclosed Assets

Assets acquired through, or in lieu of, loan foreclosures are held for sale and are initially recorded at fair value less estimated costs to sell the assets at the date of foreclosure, which becomes the "cost" basis of the asset. Subsequent to foreclosure, valuations are periodically performed by management and the assets are carried at the lower of cost or fair value, less estimated costs to sell the asset. Revenue and expenses from operations, changes in the valuation allowance and gains/losses on sales of foreclosed real estate are included in, or netted against, foreclosed real estate expense. Foreclosed assets are included in other assets on the Company's balance sheet and totaled $7.7 million as of December 31, 2014 as compared to $4.5 million as of December 31, 2013.

Net expenses associated with foreclosed assets are detailed below:

Income Taxes

Deferred income taxes are provided using the liability method whereby deferred tax assets are recognized for deductible temporary differences and deferred tax liabilities are recognized for taxable temporary differences. Temporary differences are the differences between the reported amounts of assets and liabilities and their tax bases. Deferred tax assets and liabilities are adjusted through the provision for income taxes for the effects of changes in tax laws and rates on the date of enactment. The Company analyzes each tax position taken in its tax returns and determines the likelihood that the position will be realized. Only tax positions that are "more likely than not" to be realized can be recognized in the Company's financial statements. For tax positions that do not meet this recognition threshold, the Company will record an unrecognized tax benefit for the difference between the position taken on the tax return and the amount recognized in the financial statements. The Company did not have any material unrecognized tax benefits or accrued interest or penalties at December 31, 2014 or 2013 or during the years then ended. No unrecognized tax benefits are expected to arise within the next twelve months. The Company's policy is to account for interest as a component of interest expense and penalties, if any, as a component of other expenses.

Transfers of Financial Assets

Transfers of financial assets, including sales of loans and loan participations, are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Company, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets and (3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity.

Treasury Stock

Common stock shares repurchased are recorded as treasury stock at cost.

Per Share Data

Basic net income per common share represents income available to common stockholders divided by the weighted-average number of common shares outstanding during the period. Diluted net income per common share reflects additional common shares that would have been outstanding if dilutive potential common shares had been issued as well as any adjustments to income that would result from the assumed issuance. Potential common shares that may be issued by the Company relate solely to outstanding common stock options and are determined using the treasury stock method or stock purchased through the Company's dividend reinvestment and stock purchase plan.

Treasury shares are not deemed outstanding for earnings per share calculations.

Off-Balance Sheet Financial Instruments

In the ordinary course of business, the Company enters into off-balance sheet financial instruments consisting of commitments to extend credit, including commercial letters of credit and standby letters of credit. Such financial instruments are recorded on the balance sheet when they become payable by the borrower to the Company.

Cash Flow Information

For purposes of the statements of cash flows, the Company considers cash and due from banks, interest-bearing deposits and federal funds sold as cash and cash equivalents.

Stock-Based Compensation

The Company recognizes compensation costs related to share-based payment transactions in the income statement based on the grant-date fair value of the stock-based compensation issued. Compensation costs are recognized over the period that an employee provides service in exchange for the award.

The cash flows resulting from the tax benefits due to deductions in excess of the compensation cost recognized for options (excess tax benefits) are classified as financing cash flows.

Advertising Costs

The Company follows the policy of charging the costs of advertising to expense as incurred.

Recent Accounting Standards

In July 2013, the Financial Accounting Standards Board (FASB) issued ASU 2013-11, Income Taxes (Topic 740), Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists. ASU 2013-11 provides that an unrecognized tax benefit, or a portion of an unrecognized tax benefit, should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carry forward, a similar tax loss, or a tax credit carry forward, except as follows: to the extent a net operating loss carry forward, a similar tax loss, or a tax credit carry forward is not available at the reporting date under the tax law of the applicable jurisdiction to settle any additional income taxes that would result from the disallowance of a tax position or the tax law of the applicable jurisdiction does not require the entity to use, and the entity does not intend to use, the deferred tax asset for such purpose, the unrecognized tax benefit should be presented in the financial statements as a liability and should not be combined with deferred tax assets. This guidance was effective for fiscal years, and interim periods within those years, that began after December 15, 2013. The adoption of this guidance did not have a material impact on our consolidated financial statements.

In January 2014, the FASB issued ASU 2014-04, Receivables-Troubled Debt Restructurings by Creditors (Subtopic 310-40), Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure. The guidance clarifies when a creditor should be considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan such that the loan should be derecognized and the real estate property recognized. This guidance is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2014. We do not believe the adoption of this guidance will have a material impact on our consolidated financial statements.

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606), which specifies how and when to recognize revenue and includes additional disclosures. ASU 2014-09 is effective for annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period, and allows for either full retrospective or modified retrospective application. Early application is not permitted. We are currently evaluating the impact ASU 2014-09 will have on our consolidated financial statements.

In August 2014, the FASB issued ASU 2014-15, Presentation of Financial Statements-Going Concern (Subtopic 310-40), Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern. ASU 2014-15 requires an entity’s management to evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date that the financial statements are issued. This guidance is effective for the annual period ending after December 15, 2016, and for annual and interim periods thereafter. Early adoption is permitted. Because ASU 2014-15 only impacts the timing and content of footnote disclosures, the adoption of this guidance will not have a material impact on our consolidated financial statements.

In November 2014, the FASB issued ASU 2014-16, Derivatives and Hedging (Topic 815), Determining Whether the Host Contract in a Hybrid Financial Instrument Issued in the Form of a Share Is More Akin to Debt or Equity. ASU 2014-16 clarifies how existing guidance should be interpreted in evaluating the economic characteristics and risks of a host contract in a hybrid financial instrument that is issued in the form of a share. ASU 2014-16 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015 and should be applied on a modified retrospective basis. We do not believe the adoption of this guidance will have a material impact on our consolidated financial statements.

Segment Reporting

The Bank acts as an independent community financial services provider and offers traditional banking and related financial services to individual consumer, business and government customers. Through its stores, the Bank offers a full array of commercial and retail financial services.

Management does not separately allocate expenses, including the cost of funding loan demand, between the commercial and retail operations of the Company. As such, discrete financial information is not available and segment reporting would not be meaningful.

Reclassifications

Certain amounts in the 2013 and 2012 financial statements have been reclassified to conform to the 2014 presentation format. Such reclassifications had no impact on the Company's net operations and stockholders' equity.

During 2014, the Company sold five agency collateralized mortgage obligations (CMOs) with a total fair market value of $30.9 million and realized total net losses of $82,000. One security with a fair market value of $614,000 was sold from the held to maturity (HTM) portfolio, however, it was an amortizing security that had already returned more than 85% of its principal and could be sold without tainting the Company's intent with respect to the remaining HTM portfolio. The Company had no securities that were called by their respective issuers.

During 2013, the Company sold a total of 28 securities with a combined fair market value of $98.5 million. The Company realized net pretax gains of $512,000. Of the total, 16 securities with a combined fair market value of $76.3 million had been classified as available for sale. Securities sold from available for sale included 14 CMOs and two mortgage-backed securities (MBSs). Ten agency MBSs and one agency CMO with a combined fair market value of $12.2 million had been classified as held to maturity, however, in each case the current par value had paid down to less than 15% of its purchased par value so they could be sold without tainting the Company's intent with respect to the remaining HTM portfolio. In addition, one corporate bond with a fair market value of $10.0 million had been classified as held to maturity but was sold within three months of its final maturity. In addition to its sales, the Company had two agency debentures called during 2013. The combined par value was $50.0 million with a net pretax gain of $152,000.

In 2012, the Company sold a total of 48 securities with a combined fair market value of $305.4 million. The Company realized net pretax gains of $1.1 million, with a related tax expense of $368,000. Of the total, 41 securities with a combined fair market value of $299.3 million had been classified as available for sale. Seven agency MBSs with a fair market value of $6.1 million had been classified as held to maturity, however, in each case the current par value had paid down to less than 15% of its purchased par value so they could be sold without tainting the Company's intent with respect to the remaining HTM portfolio. Securities sold from available for sale included eight private-label CMOs with a combined fair market value of $20.1 million. The Company no longer owns any private-label CMOs. In addition to its sales, the Company had a total of 11 agency debentures and one corporate debenture called during 2012. The combined par value was $160.3 million and the Company realized no gain or loss on the calls.

The Company does not maintain a trading portfolio and there were no transfers of securities between the AFS and HTM portfolios. The Company uses the specific identification method to record security sales.

At December 31, 2014 and 2013, securities with a carrying value of $698.8 million and $691.3 million, respectively, were pledged to secure public deposits and for other purposes as required or permitted by law.

The following table summarizes the Company's gains and losses on the sales or calls of debt securities and credit losses (if any) recognized for the OTTI of investments:


(in thousands)	Gross Realized Gains				Gross Realized Losses				OTTI Credit Losses				Net Gains (Losses)

In determining fair market values for its portfolio holdings, the Company receives information from a third party provider which management evaluates and corroborates using amounts from one of its securities brokers. Under the current guidance, these values are considered Level 2 inputs, based upon mathematically derived matrix pricing and observed data from similar assets. They are not Level 1 direct quotes, nor do they reflect Level 3 inputs that would be derived from internal analysis or judgment. As the Company does not manage a trading portfolio and typically only sells from its AFS portfolio in order to manage interest rate risk or credit exposure, direct quotes, or street bids, are warranted on an as-needed basis only.

The following tables show the fair value and gross unrealized losses associated with the Company's investment portfolio, aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position:

The Company's investment securities portfolio consists primarily of U.S. Government agency debentures, U.S. Government sponsored agency MBSs, agency CMOs, corporate bonds and municipal bonds. The Company considers securities of the U.S. Government sponsored agencies and the U.S. Government MBSs/CMOs to have little credit risk because their principal and interest payments are backed by an agency of the U.S. Government.

The unrealized losses in the Company's investment portfolio at December 31, 2014 were associated with two distinct types of securities. The first type, those backed by the U.S. Government or one of its agencies, included 11 debentures, 28 CMOs and four MBSs. Management believes that the unrealized losses on these investments were primarily caused by the movement of interest rates from the date of purchase and notes the contractual cash flows of those investments are guaranteed by an agency of the U.S. Government. Accordingly, it is expected that the securities would not be settled at a price less than the amortized cost of the Company's investment. The Company also owns five municipal bonds that were in an unrealized loss position as of December 31, 2014. In all cases, the bonds are general obligations of either a Pennsylvania municipality or school district and are backed by the ad valorem taxing power of the entity. In all cases, the bonds carry an investment grade rating of no lower than single-A by either Moody's or Standard and Poors. The Company, however, conducts its own periodic, independent review and believes the unrealized losses in its municipal bond portfolio are the result of movements in long-term interest rates and are not reflective of any credit deterioration. The Company does not intend to sell these debt securities prior to recovery and it is more likely than not that the Company will not have to sell these debt securities prior to recovery.

The Company did not hold private-label CMOs as of December 31, 2014 or December 31, 2013. The table below rolls forward the cumulative life to date credit losses which have been recognized in earnings for the private-label CMOs for the year ended December 31, 2012.

Loans Receivable and Allowance For Loan Losses	Loans Receivable and Allowance for Loan Losses

	Loans receivable that management has the intent and ability to hold for the foreseeable future, or until maturity or payoff, are stated at their outstanding unpaid principal balances, net of an allowance for loan losses (allowance or ALL) and any deferred fees and costs. Interest income is accrued on the unpaid principal balance. Loan origination fees and costs are deferred and recognized as an adjustment of the yield (interest income) of the related loans. The Company is generally amortizing these amounts over the contractual life of the loan or to the first review date if the loan is on demand. Certain qualifying loans of the Bank totaling $554.3 million at December 31, 2014, collateralize a letter of credit and a line of credit commitment the Bank has with the FHLB.

	A summary of the Bank's loans receivable is as follows:


		December 31,

	Less: allowance for loan losses	24,998				23,110

	Net loans receivable	$	1,973,536			$	1,727,762


	Certain directors and executive officers of the Company, including their associates and companies, have loans with the Bank. Such loans were made in the ordinary course of business at the Bank's normal credit terms including interest rates and collateralization, similar to those prevailing at the time for comparable loans with persons not related to the Bank and do not represent more than a normal risk of collection. Total loans to these persons and companies amounted to approximately $7.1 million and $6.9 million at December 31, 2014 and 2013, respectively. New advances of $2.0 million were made and repayments totaled $1.8 million during 2014.


	The following table summarizes nonaccrual loans by loan type:


		December 31,
	(in thousands)	2014				2013
	Nonaccrual loans:
	Commercial and industrial	$	11,634			$	10,217

	Commercial tax-exempt	—				—

	Owner occupied real estate	7,416				4,838

	Commercial construction and land development	3,228				8,587

	Commercial real estate	5,824				6,705

	Residential	4,987				7,039

	Consumer	1,877				2,577

	Total nonaccrual loans	$	34,966			$	39,963


	Generally, the Bank's policy is to move a loan to nonaccrual status when it becomes 90 days past due or when the Company does not believe it will collect all of the contractual principal and interest payments. In addition, when a loan is placed on nonaccrual status, unpaid interest credited to income in the current year is reversed and unpaid interest accrued in prior years is charged against the ALL. Interest received on nonaccrual loans generally is either applied against principal or reported as interest income, according to management's judgment as to the collectibility of principal. If a loan is substandard and accruing, accrued interest is recognized as income. Once a loan is on nonaccrual status, it is not returned to accrual status unless loan payments have been current for at least six consecutive months and the borrower and/or any guarantors demonstrate the ability to repay the loan in accordance with its contractual terms. Under certain circumstances such as bankruptcy, if a loan is under collateralized, or if the borrower and/or guarantors do not show evidence of the ability to pay, the loan may be placed on nonaccrual status even though it is not past due by 90 days or more. Therefore, the total nonaccrual loan balance of $35.0 million exceeds the balance of total loans that are 90 days past due of $16.9 million at December 31, 2014, as presented in the aging analysis tables that follow.

	No additional funds were committed on nonaccrual loans including restructured loans that were nonaccruing. Typically, commitments are canceled and no additional advances are made when a loan is placed on nonaccrual.

	The following tables detail the age analysis of past due loans receivable:

The Bank may create a specific allowance for all of or a part of a particular loan in lieu of a charge-off or charge-down as a result of management's evaluation of impaired loans. In these instances, the Bank has determined that a loss is not imminent based upon available information surrounding the credit at the time of the analysis including, but not limited to, unresolved legal matters; however, management believes an allowance is appropriate to acknowledge the probable risk of loss.

Typically, commercial construction and land development and commercial real estate loans present a greater risk of nonpayment by a borrower than other types of loans. The market value of and cash flow from real estate, particularly real estate held for investment, can fluctuate significantly in a relatively short period of time. Commercial and industrial, tax exempt and owner occupied real estate loans generally carry a lower risk factor comparatively within the commercial portfolio because the repayment of these loans relies primarily on the cash flow from a business which is more stable and predictable.

Consumer loan collections are dependent on the borrower's continued financial stability and thus are more likely to be affected by adverse personal circumstances. Consumer and residential loans are also impacted by the market value of real estate. Furthermore, the application of various federal and state laws, including bankruptcy and insolvency laws, may limit the amount that can be recovered on these loans. The risk of nonpayment is affected by changes in economic conditions, the credit risks of a particular borrower, the term of the loan and, in the case of a collateralized loan, the value of the collateral and other factors.

Management bases its quantitative analysis of probable future loan losses (when determining the ALL) on those loans collectively reviewed for impairment on a two-year period of actual historical losses. Management continuously assesses the quality of the Company's loan portfolio in conjunction with the current state of the economy and its impact on our borrowers repayment ability and on loan collateral values in order to determine the appropriate historical loss period to use in our quantitative analysis. Management may increase or decrease the historical loss period at some point in the future based on the state of the local, regional and national economies and other factors.

The qualitative factors such as changes in levels and trends of charge-offs and delinquencies; material changes in the mix, volume or duration of the loan portfolio; changes in lending policies and procedures including underwriting standards; changes in the experience, ability and depth of lending management and other relevant staff; the existence and effect of any concentrations of credit; changes in the overall values of collateral; changes in the quality of the loan review program and changes in national and local economic trends and conditions among other things, are factors which have not been identified by the quantitative analysis. The determination of qualitative factors inherently involves a higher degree of subjectivity and considers risk factors that may not have yet manifested themselves in historical loss experience.

Impaired loans averaged approximately $46.7 million, $59.0 million and $63.6 million during 2014, 2013 and 2012, respectively. All nonaccrual loans are considered impaired and interest income is handled as discussed earlier in the nonaccrual section of this Note 4. Interest income continued to accrue on impaired loans that were still accruing and totaled $577,000, $799,000 and $1.2 million during 2014, 2013 and 2012, respectively.

The Bank assigns the following loan risk ratings to commercial loans as credit quality indicators of its loan portfolio: pass, special mention, substandard accrual, substandard nonaccrual and doubtful. Monthly, management tracks loans that are no longer pass rated. We review the cash flow, operating results and financial condition of the borrower and any guarantors, as well as the collateral position against established policy guidelines as a means of providing a targeted list of loans and loan relationships that require additional attention. Special mention loans are those loans that are currently adequately protected, but potentially weak. The potential weaknesses may, if not corrected, weaken the loan's credit quality or inadvertently jeopardize the Bank's credit position in the future. Substandard accrual and substandard nonaccrual assets are characterized by well-defined weaknesses that jeopardize the liquidation of the debt and by the possibility that the Bank will sustain some loss if the weaknesses are not corrected. Substandard accrual loans would move from accrual to nonaccrual when the Bank does not believe it will collect all of its contractual principal and interest payments. Some identifiers used to assess collectibility are as follows: when the loan is 90 days past due in principal or interest, there are triggering events in the borrower's or any guarantor's financial statements that show continuing deterioration, the borrower's or any guarantor's source of repayment is depleting or if bankruptcy or other legal matters are present, regardless if the loan is 90 days past due or not. Doubtful loans have all of the weaknesses inherent in those classified as substandard accrual and substandard nonaccrual with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently known facts, conditions and values, highly questionable and improbable. Pass rated loans are reviewed throughout the year through the recurring review process of an independent loan review function and through the application of other credit metrics.
Credit quality indicators for commercial loans broken out by loan type at year end are presented in the following tables. There were no loans classified as doubtful for the years ended December 31, 2014 or December 31, 2013.

A troubled debt restructuring (TDR) is a loan in which the contractual terms have been modified, resulting in the Bank granting a concession to a borrower which is experiencing financial difficulties, in order for the Bank to have a greater chance of collecting the indebtedness from the borrower. An additional benefit to the Bank in granting a concession is to possibly avoid foreclosure or repossession of loan collateral at a time when collateral values are low.

The following table presents the recorded investment at the time of restructure of new TDRs and their concession, modified during the twelve month periods ended December 31, 2014, 2013 and 2012. The recorded investment at the time of restructure was the same pre-modification and post-modification, therefore there was no financial effect of the modification on the recorded investment. The loans included are considered TDRs as a result of the Bank implementing one or more of the following concessions: granting a material extension of time, entering into a forbearance agreement, adjusting the interest rate, accepting interest only payments for an extended period of time, a change in the amortization period or a combination of any of these concessions.

Included in the 39 contracts in the table above for the twelve month period ended December 31, 2014, are ten contracts totaling $9.7 million that had been restructured prior to December 31, 2013 and which had additional concessions granted during 2014.
One commercial and industrial loan identified as an accruing TDR had an unused commitment totaling $14,000 at December 31, 2014 as compared to one commercial construction and land development loan identified as an accruing TDR which had an additional unused commitment totaling $43,000 at December 31, 2013.

The following table represents loans receivable modified as TDRs within the 12 months previous to December 31, 2014, 2013 and 2012, respectively, and that subsequently defaulted during the 12 month periods ended December 31, 2014, 2013 and 2012, respectively. The Bank's policy is to consider a loan past due and in default if payment is not received on or before the due date.

Of the 23 contracts that subsequently payment defaulted during the year ended December 31, 2014, seven contracts totaling $2.4 million were still in payment default at December 31, 2014.

All TDRs are considered impaired and, therefore, are individually evaluated for impairment in the calculation of the ALL. Prior to their classification as TDRs, certain of these loans had been collectively evaluated for impairment in the calculation of the ALL.

Guarantees [Abstract]
Loan Commitments and Standby Letters of Credit	Loan Commitments and Standby Letters of Credit

	Loan commitments are made to accommodate the financial needs of the Bank's customers. Standby letters of credit commit the Bank to make payments on behalf of customers when certain specified future events occur. They primarily are issued to facilitate a customers' normal course of business transactions. Standby performance letters of credit are written conditional commitments issued by the Bank to guarantee the performance of a customer to a third party. Almost all of the Company's standby letters of credit have expired unfunded.

	The credit risk associated with letters of credit is essentially the same as that of traditional loan facilities and are subject to the Bank's normal underwriting and credit policies. Since the majority of the commitments are expected to expire without being drawn upon, the total commitment amount does not necessarily represent future funding requirements. Commitments generally have fixed expiration dates or other termination clauses. Management believes that the proceeds obtained through a liquidation of collateral, the enforcement of guarantees and normal collection activities against the borrower would be sufficient to cover the potential amount of future payment required under the corresponding letters of credit.

	The Bank does not issue any guarantees that would require liability recognition or disclosure, other than standby letters of credit. There was no liability for guarantees under standby letters of credit as of December 31, 2014 and December 31, 2013.

	In addition to standby letters of credit, in the normal course of business there are unadvanced loan commitments. At December 31, 2014, the Company had $637.1 million in total unused commitments, including the standby letters of credit. Management does not anticipate any material losses as a result of these transactions.
	The Company's maximum exposure to credit loss for loan commitments (unfunded loans and unused lines of credit, including home equity lines of credit) and standby letters of credit outstanding were as follows:


		December 31,

Concentrations of Credit Risk	Concentrations of Credit Risk

	The Company's loan portfolio is geographically concentrated principally to borrowers throughout Cumberland, Dauphin, York, Lebanon, Lancaster and Berks counties of Pennsylvania where it has full-service stores.

	The Company’s loan portfolio also has a significant concentration of loans related to the commercial real estate industry, in which the primary source of repayment is the sale or refinancing of commercial real estate or collection of rental payments. Commercial real estate loans present a greater risk of nonpayment by a borrower than other types of loans. Commercial real estate loans are collateralized by the related project (principally multi-family residential, office building, lodging, land development and other properties) and typically require owner guarantees. Maximum terms and maximum advance rates are established according to our underwriting guidelines based on our assessment of the industry and overall risk of the project being financed. Loans and loan commitments for commercial real estate and commercial construction and land development aggregated to $823.6 million at December 31, 2014.

	At December 31, 2014, the Company had a net deferred tax asset of $9.0 million. An analysis was conducted to determine if a valuation allowance against its deferred tax assets was required.

Management concluded that a valuation allowance was not necessary at December 31, 2014.

	In 2014, a tax benefit of $29,000 was recognized on net securities losses, compared to tax expense of $232,000 and $368,000 recognized on net securities gains during 2013 and 2012, respectively. The Company received a tax benefit on its federal income tax return totaling $191,000 and $51,000 for 2014 and 2013, respectively, related to the exercise of nonqualified stock options and disqualified dispositions of employee stock from options exercised. No such tax benefit was received during 2012. The Company, or one of its subsidiaries, files income tax returns in the U.S. Federal jurisdiction and various states.

	At December 31, 2014 and 2013, 40,000 shares of the Company's Series A $10 par value noncumulative nonvoting preferred stock was issued and outstanding. The preferred stock is redeemable at the option of the Company at the price of $25 per share plus any unpaid dividends. Dividends on the preferred stock are payable quarterly at a rate of $2 per share per annum.

	The Company has a dividend reinvestment and stock purchase plan (the Plan). Holders of the Company's common stock may participate in the Plan in which cash dividends can be reinvested in common shares and voluntary cash payments of not less than $100 per month and not more than $10,000 per month can purchase additional common shares. Officers are eligible to participate immediately and employees who have been continuously employed for at least one year are also eligible to participate in the Plan through authorized payroll deductions. The minimum investment is $25 per month for employees and $50 for officers with a maximum of $10,000 per month. A total of 3,474, 2,311 and 5,917 common shares were issued pursuant to this Plan in 2014, 2013 and 2012, respectively. At December 31, 2014, the Company had reserved approximately 510,000 common shares to be issued in connection with the Plan.

	In conjunction with a planned 5% share buyback program announced in October 2014, the Company purchased 12,300 shares of its common stock for $319,000 during December 2014. The cost of this treasury stock is shown as a separate item within stockholders’ equity on the consolidated balance sheets. Through March 10, 2015, an additional 117,000 shares were purchased for $3.0 million.

	On January 23, 2015, the Company declared a $0.07 per share cash dividend on its common stock, which was paid on February 25, 2015, to all shareholders of record on February 4, 2015. The total amount of the dividend paid on all shares was $993,000.



	Shareholder Protection Rights Agreement (Rights Agreement)

	On February 17, 2015, the board of directors adopted a Rights Agreement and declared a dividend of one Right on each outstanding share of the Company’s common stock. The record date to determine shareholders entitled to receive the Rights was February 27, 2015. The Rights Agreement will expire on February 17, 2016.

	Until the earlier of (i) the Company’s announcing that a person or group (an Acquiring Person) has acquired 15% or more of its common stock (the Flip-in Date) and (ii) the tenth business day after any person or group commences a tender offer that will result in such person or group owning 15% or more of the Company’s common stock, the Rights will be evidenced by the common stock certificates, will automatically trade with the common stock and will not be exercisable. Thereafter, separate Rights certificates will be distributed and each Right will entitle its holder to purchase fractions of participating preferred stock having economic and voting terms similar to those of one share of common stock for an exercise price of $100.00.

	Upon the occurrence of the Flip-in Date, each Right (other than Rights beneficially owned by any Acquiring Person or transferees thereof, which Rights become void) will be exchanged for one share of the Company’s common stock, unless the board of directors determines otherwise or any person owns more than 50% of the Company’s common stock. If the board of directors determines not to effect the exchange, each Right (other than the voided ones) will entitle its holder to purchase, for the exercise price, a number of shares of the Company’s common stock having a market value of twice the exercise price. Also, if after an Acquiring Person controls the board of directors or is the owner of 50% or more of the Company’s common stock, the Company is involved in a merger or sells more than 50% of its assets or earning power and, in the case of a merger, the Acquiring Person will receive different treatment than all other shareholders or the transaction is with the Acquiring Person, each Right will entitle its holder to purchase, for the exercise price, a number of shares of common stock of the Acquiring Person having a market value of twice the exercise price.

	The Rights may generally be redeemed by the board of directors for $0.001 per Right prior to the Flip-in Date.

The Plan covers 1,000,000 authorized shares of common stock reserved for issuance upon the exercise of options granted or available for grant to employees and will expire on December 31, 2015. The Plan provides that the option price of qualified incentive stock options and nonqualified stock options will be fixed by the board of directors, but will not be less than 100% of the fair market value of the stock at the date of grant. Options granted are exercisable one year after the grant date, will vest over a four-year period and expire ten years after the grant date.

Under the Company's Directors Plan, nonemployee directors of the Company, consultants and others who are not regularly employed on a salaried basis by the Company may be entitled to an option to acquire shares, as determined by the board of directors, of the Company's common stock during each year in which the director serves on the board. The Directors Plan provides that the option price will be fixed by the board of directors, but will not be less than 100% of the fair market value of the stock on the date of the grant.

	The fair value of each option grant was established at the date of grant using the Black-Scholes option pricing model. The Company used the following assumptions:


		Years Ended December 31,
		2014		2013		2012
	Weighted-average risk-free interest rates	2	%	1.4	%	1.7	%
	Expected dividend yields	—	%	—	%	—	%
	Volatility factors of expected market price of Company's common stock	34	%	41	%	48	%
	Assumed forfeiture rates	10.3	%	11.2	%	9	%
	Weighted-average expected terms of options, in years	7.2		7.5		7.5

	Options vesting annually	25	%	25	%	25	%

	The following table details the Company's stock-based compensation expense and related tax benefit associated with this expense:


		Years Ended December 31,
	(in thousands)	2014			2013			2012
	Stock-based compensation expense	$	811		$	948		$	1,082

	Tax benefit associated with compensation expense	173			169			171


	As of December 31, 2014, there was $1.3 million of total unrecognized compensation cost related to nonvested stock option awards. The expense will be recognized through 2018, with a weighted-average period of 2.3 years.

	Combined stock option transactions under both Plans were as follows:

	Cash received from the exercise of options for 2014 and 2013 was $932,000 and $304,000, respectively, and was $0 for 2012.

	Options exercisable and outstanding at December 31, 2014 had an intrinsic value of $5.9 million. The intrinsic value of options exercised was $716,000 and $183,000 in 2014 and 2013, respectively. There were no options exercised in 2012.

	The Company allows for option exercises to be paid for in cash or in whole or in part with Metro stock owned by the optionee. The value of the stock used to exercise the options is the fair market value on the date of exercise. Stock option exercises paid for with the Company's stock included 6,185 shares for the year ended December 31, 2014.

Regulatory Matters [Abstract]
Regulatory Matters	Regulatory Matters

	The Company is a legal entity separate and distinct from its subsidiary, the Bank. There are various legal and regulatory limitations on the extent to which the Bank can, among other things, finance, or otherwise supply funds to, the Company. Specifically, dividends from the Bank are the principal source of the Company's cash funds and there are certain legal restrictions under Pennsylvania law and Pennsylvania banking regulations on the payment of dividends by state-chartered banks. The relevant regulatory agencies also have authority to prohibit the Company and the Bank from engaging in what, in the opinion of such regulatory body, constitutes an unsafe or unsound banking practice. The payment of dividends from the Bank to the Company could, depending upon the financial condition of the Company and the Bank, be deemed to constitute such an unsafe or unsound practice.

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

	Quantitative measures established by regulation to ensure capital adequacy require the Company and the Bank to maintain minimum amounts and ratios (set forth below) of total and Tier 1 capital (as defined in the regulations) to risk-weighted assets and of Tier 1 capital to average assets. Management believes, as of December 31, 2014, that the Company and the Bank meet all capital adequacy requirements to which they are subject.

	As of December 31, 2014, the Bank was categorized as well-capitalized under the regulatory framework for prompt corrective action. To be categorized as well-capitalized the Bank must maintain minimum total risk-based, Tier 1 risk-based and Tier 1 leverage ratios as set forth in the table below. There are no conditions or events since that notification that management believes have changed the Bank's category.
	The following table presents the risk-based and leverage capital amounts and ratios for the Company and the Bank:

	On April 29, 2010, the Bank consented and agreed to the issuance of a Consent Order (Order) by the FDIC, the Bank's federal banking regulator and a substantially similar consent order by the Pennsylvania Department of Banking, which in 2012 was renamed the Pennsylvania Department of Banking and Securities (PaDOB). The Order required the Bank to take all necessary steps, consistent with the Order and sound banking practices, to correct and prevent certain unsafe or unsound banking practices and violations of law or regulation alleged by the FDIC to have been committed by the Bank. Among other things, the Order required certain analyses and assessments, including an analysis and assessment of the Bank Secrecy Act (BSA) and Office of Foreign Assets Control (OFAC) staffing needs and qualifications and an analysis and assessment of the independence and performance of the Company's directors and senior executive officers. It also required the development, adoption and implementation of a system of internal controls designed to ensure full compliance with BSA and OFAC provisions; training programs to ensure that all appropriate personnel are aware of and can comply with applicable requirements of BSA and OFAC provisions; periodic reviews by internal and external auditors of compliance with BSA and OFAC provisions; and a review by an independent third party of the Bank's compliance with the Order. Most of these Order remediation-related expenses were incurred prior to 2012. The Bank paid a nonrecurring $1.5 million civil money penalty assessed by the FDIC during the third quarter of 2012 associated with alleged deficiencies as noted in the Order. The expense impact of the civil money penalty is included in the regulatory assessments line on the consolidated statement of income for the year ended December 31, 2012. The FDIC terminated the Order effective October 16, 2012. Earlier that year, the PaDOB had terminated their substantially similar order effective April 12, 2012.

	Regulatory Capital Changes
	In July 2013, the federal banking agencies issued final rules to implement the Basel III regulatory capital reforms and changes required by the Dodd-Frank Wall Street Reform and Consumer Protection Act (Dodd-Frank Act). The phase-in period for community banking organizations begins January 1, 2015, while larger institutions (generally those with assets of $250 billion or more) began compliance on January 1, 2014. The final rules call for the following capital requirements:

	•	A minimum ratio of common equity tier 1 capital to risk-weighted assets of 4.5%.


	•	A minimum ratio of tier 1 capital to risk-weighted assets of 6%.


	•	A minimum ratio of total capital to risk-weighted assets of 8% (no change from the current rule).


•	A minimum leverage ratio of 4%.

In addition, the final rules establish a common equity tier 1 capital conservation buffer of 2.5% of risk-weighted assets applicable to all banking organizations. If a banking organization fails to hold capital above the minimum capital ratios and the capital conservation buffer, it will be subject to certain restrictions on capital distributions and discretionary bonus payments. The phase-in period for the capital conservation and countercyclical capital buffers for all banking organizations will begin on January 1, 2016.
We have evaluated these new rules and believe the Company and the Bank will be able to comply with the targeted capital ratios upon implementation of the revised requirements, as finalized.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements

	The Company uses its best judgment in estimating the fair value of its financial instruments and certain nonfinancial assets; however, there are inherent weaknesses in any estimation technique due to assumptions that are susceptible to significant change. Therefore, for substantially all financial instruments and certain nonfinancial assets, the fair value estimates herein are not necessarily indicative of the amounts the Company could have realized in a sale transaction on the dates indicated. The estimated fair value amounts have been measured as of their respective year-ends and have not been reevaluated or updated for purposes of these financial statements subsequent to those respective dates. As such, the estimated fair values of these financial instruments and certain nonfinancial assets subsequent to the respective reporting dates may be different than the amounts reported at each year-end.

	Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The Company uses the following fair value hierarchy in selecting inputs with the highest priority given to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements):

	Level 1: Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities;

	Level 2: Quoted prices in markets that are not active, or inputs that are observable either directly or indirectly, for substantially the full term of the asset or liability;

	Level 3: Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e., supported with little or no market activity).

	As required, financial and certain nonfinancial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The following table sets forth the Company's financial assets that were measured at fair value on a recurring basis by level within the fair value hierarchy:

	As of December 31, 2014 and December 31, 2013, the Company did not have any liabilities that were measured at fair value on a recurring basis.

	Impaired Loans (Generally Carried at Fair Value)

	Impaired loans that are measured at fair value on a nonrecurring basis include collateral dependent loans for which an impairment has been recorded by the Company based on the fair value of the loan's collateral, net of expected selling costs. Fair value is generally determined based upon independent third party appraisals or valuations of the collateral properties. The discount rates used on collateral dependent loans vary based on the type of collateral. The range of discount rates used for real estate collateral ranged from 10% to 35% and the weighted-average rate was 20% and 21% as of December 31, 2014 and December 31, 2013, respectively; inventory and equipment is generally discounted at 50% and accounts receivable are generally discounted by 20%. These assets are included as Level 3 fair values, based upon the lowest level of unobservable input that is significant to the fair value measurements. The fair value consists of the loan balance less any valuation allowance. The valuation allowance amount is calculated as the difference between the recorded investment in a loan and the discounted collateral value.

	At December 31, 2014, the cumulative fair value of nine impaired collateral dependent loans with individual allowance allocations totaled $3.9 million, net of valuation allowances of $5.6 million, and the current fair value of impaired collateral dependent loans that were partially charged off during 2014 totaled $5.3 million, net of charge-offs of $2.4 million. At December 31, 2013, the cumulative fair value of six impaired collateral dependent loans with individual allowance allocations totaled $5.7 million, net of valuation allowances of $5.6 million, and the current fair value of impaired collateral dependent loans that were partially charged off during 2013 totaled $10.4 million, net of charge-offs of $2.9 million. The Company's impaired loans are more fully discussed in Note 4.

	Foreclosed Assets (Carried at Lower of Cost or Fair Value)

	The fair value of real estate acquired through foreclosure is based on independent third party appraisals of the properties, less estimated selling costs. A standard discount rate of 15%, to cover estimated costs to sell the property, is generally used on the most recent appraisal to determine the fair value of the real estate. These assets are included as Level 3 fair values, based upon the lowest level of unobservable input that is significant to the fair value measurements. At December 31, 2014, there were no foreclosed assets with a valuation allowance recorded subsequent to initial foreclosure. At December 31, 2013, the carrying value of foreclosed assets with valuation allowances recorded subsequent to initial foreclosure was $1.9 million, which was net of a valuation allowance of $62,000.

	The determination of the fair value of assets measured on a nonrecurring basis is sensitive to changes in economic conditions and can fluctuate in a relatively short period of time. For assets measured at fair value on a nonrecurring basis, the fair value measurements by level within the fair value hierarchy used were as follows:


				Fair Value Measurements at Reporting Date Using
Description				Quoted Prices in			Significant Other			Significant
				Active Markets for			Observable Inputs			Unobservable

Foreclosed assets	1,938			—			—			1,938

Total	$	18,073		$	—		$	—		$	18,073


The Company's policy is to recognize transfers between levels as of the beginning of the period. There were no transfers between levels 1 and 2 or between levels 2 and 3 for the twelve months ended December 31, 2014.

The following information should not be interpreted as an estimate of the fair value of the entire Company since a fair value calculation is only provided for a limited portion of the Company's assets and liabilities. Due to a wide range of valuation techniques and the degree of subjectivity used in making the estimates, comparisons between the Company's disclosures and those of other companies may not be meaningful. The following valuation techniques were used to estimate the fair values of the Company's financial instruments at December 31, 2014 and 2013:



Cash and Cash Equivalents (Carried at Cost)

Cash and cash equivalents include cash and balances due from banks, all of which have original maturities of 90 days or less. The carrying amounts reported in the balance sheet for cash and short-term instruments approximate those assets' fair values.

Securities

The fair value of securities available for sale (carried at fair value) and held to maturity (carried at amortized cost) are determined by matrix pricing (Level 2), which is a mathematical technique used widely in the industry to value debt securities without relying exclusively on quoted market prices for the specific securities but rather by relying on the securities' relationship to other benchmark prices. In determining fair market values for its portfolio holdings, the Company receives information from a third party provider which management evaluates and corroborates. Under the current guidance, these values are considered Level 2 inputs, based upon mathematically derived matrix pricing and observed data from similar assets. They are not Level 1 direct quotes, nor do they reflect Level 3 inputs that would be derived from internal analysis or judgment. As the Company does not manage a trading portfolio and typically only sells from its AFS portfolio in order to manage interest rate risk or credit exposure, direct quotes, or street bids, are warranted on an as-needed basis only.

Loans Held for Sale (Carried at Lower of Cost or Fair Value)

The fair value of loans held for sale is determined, when possible, using quoted secondary-market prices. If no such quoted prices exist, the fair value of a loan is determined using quoted prices for a similar loan or loans, adjusted for the specific attributes of that loan. The Company did not write down any loans held for sale during the years ended December 31, 2014 and 2013.

Loans Receivable (Carried at Cost)

The fair value of loans receivable, excluding all nonaccrual loans and accruing loans deemed impaired loans with specific loan allowances, are estimated using a discounted cash flow analysis, using market rates at the balance sheet date that reflect the credit and interest rate-risk inherent in the respective loans. Projected future cash flows are calculated based upon contractual maturity, projected repayments and prepayments of principal. Generally, for variable rate loans that reprice frequently and with no significant change in credit risk, fair values are based on carrying values.

Restricted Investment in Bank Stock (Carried at Cost)

The carrying amount of restricted investments in bank stock approximates fair value and considers the limited marketability of such securities. The restricted investments in bank stock consisted of FHLB and ACBB stock at December 31, 2014 and 2013.

Accrued Interest Receivable and Payable (Carried at Cost)

The carrying amount of accrued interest receivable and accrued interest payable approximates its fair value.

Deposit Liabilities (Carried at Cost)

The fair values disclosed for demand deposits (e.g., interest and noninterest-bearing checking) are, by definition, equal to the amount payable on demand at the reporting date (i.e., their carrying amounts). The fair value of savings and money market accounts are reported based on the carrying amount. Fair values for fixed-rate certificates of deposits (CDs) are estimated using a discounted cash flow calculation that applies interest rates currently being offered in the market on certificates to a schedule of aggregated expected monthly maturities on time deposits.

Short-Term Borrowings (Carried at Cost)

The carrying amounts of short-term borrowings approximate their fair values.

Long-Term Debt (Carried at Cost)

Long-term debt was estimated using a discounted cash flow analysis, based on quoted prices from a third party broker for new debt with similar characteristics, terms and remaining maturity. The price was obtained in an inactive market where these types of instruments are not traded regularly.

Off-Balance Sheet Financial Instruments (Disclosed at Cost)

Fair values for the Company's off-balance sheet financial instruments (lending commitments and letters of credit) are based on fees currently charged in the market to enter into similar agreements, taking into account, the remaining terms of the agreements and the counterparties' credit standing.
The estimated fair values of the Company's financial instruments were as follows:

Troubled Debt Restructurings on Loan Receivables, by Concession Type	The following table presents the recorded investment at the time of restructure of new TDRs and their concession, modified during the twelve month periods ended December 31, 2014, 2013 and 2012. The recorded investment at the time of restructure was the same pre-modification and post-modification, therefore there was no financial effect of the modification on the recorded investment. The loans included are considered TDRs as a result of the Bank implementing one or more of the following concessions: granting a material extension of time, entering into a forbearance agreement, adjusting the interest rate, accepting interest only payments for an extended period of time, a change in the amortization period or a combination of any of these concessions.
