	Summary of Significant Accounting Policies
	Consolidated Financial Statements
	The consolidated balance sheet at December 31, 2013 has been derived from audited consolidated financial statements and the consolidated interim financial statements included herein have been prepared without audit pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) have been condensed or omitted pursuant to such rules and regulations. These consolidated financial statements were prepared in accordance with GAAP for interim financial statements and with instructions for Form 10-Q and Regulation S-X Section 210.10-01. Further information on Metro Bancorp, Inc.'s (Metro or the Company) accounting policies are available in Note 1 (Significant Accounting Policies) of the Notes to Consolidated Financial Statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2013. The accompanying consolidated financial statements reflect all adjustments that are, in the opinion of management, necessary to reflect a fair statement of the results for the interim periods presented. Such adjustments are of a normal, recurring nature.
	These consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2013. Events occurring subsequent to the balance sheet date through the date of issuance have been evaluated for potential recognition or disclosure in the consolidated financial statements. The results for the six months ended June 30, 2014 are not necessarily indicative of the results that may be expected for the year ending December 31, 2014.
	The consolidated financial statements include the accounts of the Company and its consolidated subsidiaries including Metro Bank (the Bank). All material intercompany transactions have been eliminated.
	Use of Estimates
	The consolidated financial statements are prepared in conformity with 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.
	Recent Accounting Standards
	In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update 2014-09, Revenue from Contracts with Customers (Topic 606)(“ASU 2014-09”), which specifies how and when to recognize revenue and includes additional disclosures. ASU 2014-09 will be effective for financial statements issued for the first interim period within annual reporting periods beginning after December 15, 2016, and does not permit early adoption. We will adopt ASU 2014-09 in the first quarter of 2017 and are currently evaluating the impact it will have on our Financial Statements.
	In July 2013, FASB issued guidance on the presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carry forward, a Similar Tax Loss, or a Tax Credit Carry forward exists. 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. The effective date of this update for public entities is for fiscal years and interim periods 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, FASB clarified the Receivables – Troubled Debt Restructurings by Creditors guidance regarding 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. The effective date of the adoption of this guidance is for interim and annual reporting periods beginning after December 15, 2014. We do not believe the adoption of the amendment to this guidance will have a material impact on our consolidated financial statements.
	Reclassifications
	Certain amounts in the 2013 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.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]	'
Stock-Based Compensation	'
	Stock-based Compensation
	The fair value of each stock option grant was established at the date of grant using the Black-Scholes option pricing model. The Black-Scholes model used the following weighted-average assumptions for options granted during the six months ended June 30, 2014 and 2013, respectively: risk-free interest rates of 2.0% and 1.4%; volatility factors of the expected market price of the Company's common stock of 34% and 41%; assumed forfeiture rates of 10.30% and 11.16%; weighted-average expected lives of the options of 7.2 years and 7.5 years; and no cash dividends in either year. For the six months ended June 30, 2014 and 2013, respectively, options vest at 25% per year after one year from date of grant. Using these assumptions, the weighted-average fair value of options granted for the six months ended June 30, 2014 and 2013 was $7.72 and $7.54 per option, respectively. In the first six months of 2014, the Company granted 116,990 options to purchase shares of the Company's stock at exercise prices ranging from $19.55 to $21.57 per share.
	The Company recorded net stock-based compensation expense of approximately $313,000 and $499,000 during the first six months ended June 30, 2014 and June 30, 2013, respectively. In accordance with Financial Accounting Standards Board (FASB) guidance on stock-based payments, during the first quarters of 2014 and 2013 the Company reversed $238,000 and $135,000, respectively, of expense that had been recorded in prior periods as a result of the reconcilement of projected option forfeitures to actual option forfeitures for all stock options granted during the first quarters of 2010 and 2009, respectively.

	During the second quarter of 2014, the Company did not sell any securities and had no securities that were called by their respective issuers.
	During the second quarter of 2013, the Company sold 10 securities with a total fair market value of $29.0 million. The Company had no agency debentures that were called by their respective issuers. In total, the Company realized net securities losses of $9,000. Of the investments sold, none were from the held to maturity (HTM) portfolio.
	During the first six months of 2014, the Company sold one security with a fair market value of $614,000 and realized a gain of $11,000. The security was from the 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 remaining HTM portfolio. The Company had no securities that were called by their respective issuers.
	During the first six months of 2013, the Company sold 21 securities with a total fair market value of $89.9 million. The Company also had $50.0 million of agency debentures that were called by their respective issuers. In total, the Company realized net security gains of $21,000. Of the investments sold, five were from the HTM portfolio, four of which were amortizing securities that had already returned at least 85% of their respective principal, and one of which was a corporate bond within three months of its maturity date. In all cases, these could be sold without tainting the remaining HTM portfolio.
	The Company does not maintain a trading portfolio and there were no transfers of securities between the available for sale (AFS) and HTM portfolios. The Company uses the specific identification method to record security sales.
	At June 30, 2014, securities with a carrying value of $667.3 million were pledged to secure public deposits and for other purposes as required or permitted by law.

	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.
	The following table shows 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 of U.S. Government agency debentures, U.S. Government sponsored agency mortgage-backed securities (MBSs), agency collateralized mortgage obligations (CMOs), corporate bonds and municipal bonds. The Company considers securities of the U.S. Government sponsored agencies and the U.S. Government MBS/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 June 30, 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, 34 CMOs and six 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 19 municipal bonds that were in an unrealized loss position as of June 30, 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 incur any OTTI credit losses during either the first three or six months ended June 30, 2014 or 2013.

	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 $689.7 million at June 30, 2014, collateralize a letter of credit and a line of credit commitment the Bank has with the Federal Home Loan Bank (FHLB).
	A summary of the Bank's loans receivable at June 30, 2014 and December 31, 2013 is as follows:

	The following table summarizes nonaccrual loans by loan type at June 30, 2014 and December 31, 2013:
	(in thousands)	June 30, 2014				December 31, 2013
	Nonaccrual loans:
	Commercial and industrial	$	4,291			$	10,217
	Commercial tax-exempt	—				—
	Owner occupied real estate	6,401				4,838
	Commercial construction and land development	9,028				8,587
	Commercial real estate	5,793				6,705
	Residential	6,341				7,039
	Consumer	2,479				2,577
	Total nonaccrual loans	$	34,333			$	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 Bank 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 the loan has 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. The total nonaccrual loan balance of $34.3 million exceeds the balance of total loans that are 90 days past due of $23.1 million at June 30, 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 are an age analysis of past due loans receivable as of June 30, 2014 and December 31, 2013:

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 typically 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, uncertainties as to 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 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 processes. 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 $49.1 million and $58.9 million for the six months ended June 30, 2014 and 2013, 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 certain impaired loans totaling $249,000 and $470,000 for the six months ended June 30, 2014 and 2013, respectively.
The Bank assigns loan risk ratings to commercial loans as credit quality indicators of its loan portfolio: pass, special mention, substandard accrual, substandard nonaccrual and doubtful. Monthly, we track 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 within the loan portfolio. 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 our 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 determine the 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 are presented in the following tables for the periods ended June 30, 2014 and December 31, 2013. There were no loans classified as doubtful for the periods ended June 30, 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 who 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 three and six month periods ended June 30, 2014 and 2013. 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.

Of the 17 contracts that subsequently payment defaulted during the six month period ended June 30, 2014, eight were still in payment default at June 30, 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.

	Loan Commitments and Standby Letters of Credit
	Loan commitments are made to accommodate the financial needs of the Company's customers. Standby letters of credit commit the Company to make payments on behalf of customers when certain specified future events occur. They primarily are issued to facilitate the customers' normal course of business transactions. Standby performance letters of credit are written conditional commitments issued by the Company to guarantee the performance of a customer to a third party. Historically, almost all of the Company's standby letters of credit expire unfunded.
	The credit risk associated with letters of credit is essentially the same as that of traditional loan facilities and are subject to the Company'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 Company had $35.4 million and $37.2 million of standby letters of credit at June 30, 2014 and December 31, 2013, respectively. The Company 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 for the periods ended June 30, 2014 and December 31, 2013.
	In addition to standby letters of credit, in the normal course of business there are unadvanced loan commitments. The Company had $585.1 million and $561.0 million in total unused commitments, including the standby letters of credit, at June 30, 2014 and December 31, 2013, respectively. Management does not anticipate any material losses as a result of these transactions.

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 period-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 period-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 at June 30, 2014 and December 31, 2013, respectively, by level within the fair value hierarchy:

	As of June 30, 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, measured at fair value, include those loans that the Company has measured impairment of based on the fair value of the loan's collateral. 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% at June 30, 2014 ; the weighted-average rate was 20% as of June 30, 2014 as compared to 21% at December 31, 2013; inventory is generally discounted at 50%, equipment is generally discounted by 30% to 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 present value of expected future cash flows or it is calculated based on discounted collateral values if the loan is collateral dependent.
	At June 30, 2014, the cumulative fair value of eight impaired loans with individual allowance allocations totaled $5.5 million, net of valuation allowances of $5.6 million and the current fair value of impaired loans that were partially charged off during the first six months of 2014 totaled $7.2 million at June 30, 2014, net of charge-offs of $1.8 million. At December 31, 2013, the cumulative fair value of six impaired loans with individual allowance allocations totaled $5.7 million, net of valuation allowances of $5.6 million and the current fair value of impaired 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 June 30, 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:

	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 six months ended June 30, 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 June 30, 2014 and December 31, 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 six months ended June 30, 2014 or the year ended December 31, 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 Investments 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 Atlantic Community Bankers Bank (ACBB) stock at June 30, 2014 and December 31, 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 at June 30, 2014 and December 31, 2013:

	The tax provision for federal income taxes was $2.3 million for the second quarter of 2014, compared to $1.7 million for the same period in 2013. The effective tax rate was 31% and 30% for the quarters ended June 30, 2014 and June 30, 2013, respectively.
	The tax provision for federal income taxes was $4.1 million for the first six months of 2014, compared to $3.2 million for the same period in 2013. The effective tax rates were 29% for both the first six months months ended June 30, 2014 and June 30, 2013, respectively.
	At June 30, 2014, the Company had a net deferred tax asset of $11.6 million. An analysis was conducted to determine if a valuation allowance against its deferred tax assets was required. The Company used current forecasts of future expected income, possible tax planning strategies, current and future economic and business conditions (such as the possibility of a decrease in real estate value for properties the Bank holds as collateral on loans), the probability that taxable income will continue to be generated in future periods and the cumulative losses recorded in previous years to make the assessment. Management concluded that a valuation allowance was not necessary at June 30, 2014.

Consolidated Financial Statements	'
	Consolidated Financial Statements
	The consolidated balance sheet at December 31, 2013 has been derived from audited consolidated financial statements and the consolidated interim financial statements included herein have been prepared without audit pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) have been condensed or omitted pursuant to such rules and regulations. These consolidated financial statements were prepared in accordance with GAAP for interim financial statements and with instructions for Form 10-Q and Regulation S-X Section 210.10-01. Further information on Metro Bancorp, Inc.'s (Metro or the Company) accounting policies are available in Note 1 (Significant Accounting Policies) of the Notes to Consolidated Financial Statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2013. The accompanying consolidated financial statements reflect all adjustments that are, in the opinion of management, necessary to reflect a fair statement of the results for the interim periods presented. Such adjustments are of a normal, recurring nature.
	These consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2013. Events occurring subsequent to the balance sheet date through the date of issuance have been evaluated for potential recognition or disclosure in the consolidated financial statements. The results for the six months ended June 30, 2014 are not necessarily indicative of the results that may be expected for the year ending December 31, 2014.
	The consolidated financial statements include the accounts of the Company and its consolidated subsidiaries including Metro Bank (the Bank). All material intercompany transactions have been eliminated.
Use of Estimates	'
	Use of Estimates
	The consolidated financial statements are prepared in conformity with 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.
Recent Accounting Standards	'
	Recent Accounting Standards
	In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update 2014-09, Revenue from Contracts with Customers (Topic 606)(“ASU 2014-09”), which specifies how and when to recognize revenue and includes additional disclosures. ASU 2014-09 will be effective for financial statements issued for the first interim period within annual reporting periods beginning after December 15, 2016, and does not permit early adoption. We will adopt ASU 2014-09 in the first quarter of 2017 and are currently evaluating the impact it will have on our Financial Statements.
	In July 2013, FASB issued guidance on the presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carry forward, a Similar Tax Loss, or a Tax Credit Carry forward exists. 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. The effective date of this update for public entities is for fiscal years and interim periods 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, FASB clarified the Receivables – Troubled Debt Restructurings by Creditors guidance regarding 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. The effective date of the adoption of this guidance is for interim and annual reporting periods beginning after December 15, 2014. We do not believe the adoption of the amendment to this guidance will have a material impact on our consolidated financial statements.

	Reclassifications
	Certain amounts in the 2013 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.

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 three and six month periods ended June 30, 2014 and 2013. 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.
