Summary of Significant Accounting Policies	'
	Note 1—Summary of Significant Accounting Policies
	Organization and Nature of Operations
	First Priority Financial Corp.
	First Priority Financial Corp. (“First Priority”, the “Company”) was incorporated under the laws of the Commonwealth of Pennsylvania on February 13, 2007, for the purpose of becoming the holding company of First Priority Bank (the “Bank”) and had no prior operating history. On May 11, 2007, as a result of a reorganization and merger, First Priority Bank became a wholly- owned subsidiary of First Priority.
	On May 23, 2012, First Priority and Affinity Bancorp, Inc. (“Affinity”), the holding company for Affinity Bank of PA (“Affinity Bank”), jointly announced a definitive agreement to merge their respective holding companies and bank subsidiaries. Subsequently, on February 28, 2013, the merger with Affinity was completed. Total assets acquired as a result of the merger were $175.9 million, including $77.4 million in loans, and deposits of $150.9 million. Total incremental equity resulting from the transaction was $10.1 million. Under the terms of the merger agreement, shareholders of Affinity received 0.9813 newly issued shares of First Priority in exchange for each Affinity share. A total of 1,933,665 shares of First Priority common stock were issued in connection with the merger. In conjunction with the completion of the merger, the Company also issued 1,268,576 shares of First Priority common stock as part of a private placement offering that resulted in incremental net equity proceeds of $6.6 million.
	First Priority provides banking services through First Priority Bank and does not engage in any activities other than banking and related activities. As of March 31, 2014, First Priority had total assets of $431.0 million and total shareholders’ equity of $43.6 million.
	First Priority Bank
	First Priority Bank is a state-chartered commercial banking institution which was incorporated under the laws of the Commonwealth of Pennsylvania on May 25, 2005. First Priority Bank’s deposits are insured by the FDIC up to the maximum amount permitted for all banks. As of March 31, 2014, First Priority Bank had total assets of $430.9 million, total loans of $340.1 million, total deposits of $347.4 million and total shareholder’s equity of $42.9 million.
	First Priority Bank engages in a full service commercial and consumer banking business with strong private banking and individual wealth management services. First Priority Bank offers a variety of commercial, private banking and consumer loans, mortgage products and commercial real estate financing. First Priority Bank does not engage in sub-prime lending. The Company’s operations are significantly affected by prevailing economic conditions, competition, and the monetary, fiscal, and regulatory policies of governmental agencies. Lending activities are influenced by a number of factors, including the general credit needs of individuals and small and medium-sized businesses in the Company’s market area, competition, the current regulatory environment, the level of interest rates, and the availability of funds. Deposit flows and costs of funds are influenced by prevailing market rates of interest, competition, account maturities, and the level of personal income and savings in the market area.
	First Priority Bank also offers certain financial planning and investment management services. These investment services are provided by First Priority Financial Services, a Division of First Priority Bank, through an agreement with a third party provider. In addition, various life insurance products are offered through First Priority Bank, and the Bank has also entered into solicitation agreements with several investment advisors to provide portfolio management services to customers of the Bank.
	First Priority Bank currently seeks deposits and commercial and consumer banking relationships through its ten banking offices. The Bank provides deposit products that include checking, money market and savings accounts, and certificates of deposit as well as other deposit services, including cash management and electronic banking products and online account opening capabilities. The Bank obtains funding in the local community by providing excellent service and competitive rates to its customers and utilizes electronic and print media advertising to attract current and potential deposit customers. The Bank also uses brokered certificates of deposit as a cost effective funding alternative.
	Basis of Presentation
	The accompanying unaudited consolidated financial statements were prepared in accordance with instructions to Form 10-Q, and therefore, do not include information or all footnotes necessary for a complete presentation of financial position, results of operations and cash flows in conformity with accounting principles generally accepted in the United States (“GAAP”). However, all normal recurring adjustments that, in the opinion of management, are necessary for a fair presentation of these financial statements have been included. These financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto for First Priority Financial Corp. for the year ended December 31, 2013, included in the Company’s Form 10-K filed with the Securities and Exchange Commission on March 28, 2014. The results of interim periods presented are not necessarily indicative of the results that may be expected for the year ending December 31, 2014.
	The accompanying unaudited consolidated financial statements consist of the parent company, First Priority Financial Corp. and its consolidated wholly owned subsidiary, First Priority Bank. The consolidated balance sheets and related statements of income of the Company are substantially the same as the consolidated balance sheets and related statements of income of the Bank. All significant intercompany accounts and transactions have been eliminated in consolidation.
	Subsequent Events
	The Company has evaluated subsequent events for potential recognition and/or disclosure through the date that these financial statements were issued.
	Estimates
	The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, stock-based compensation, impairment of goodwill, other than temporary impairment of investment assets, and the valuation of deferred tax assets and other real estate.
	Acquired Loans
	Acquired loans are initially recorded at their acquisition date fair values. The carryover of allowance for loan losses is prohibited as any credit losses in the loans are included in the determination of the fair value of the loans at the acquisition date. Fair values for acquired loans are based on a discounted cash flow methodology that involves assumptions and judgments as to credit risk, prepayment risk, liquidity risk, default rates, loss severity, payment speeds, collateral values and discount rate.
	Acquired loans that have evidence of deterioration in credit quality since origination and for which it is probable, at acquisition, that the Company will be unable to collect all contractually required payments are accounted for as impaired loans under ASC 310-30. The excess of cash flows expected at acquisition over the estimated fair value is referred to as the accretable discount and is recognized into interest income over the remaining life of the loans. The difference between contractually required payments at acquisition and the cash flows expected to be collected at acquisition is referred to as the non-accretable discount. The non-accretable discount represents estimated future credit losses expected to be incurred over the life of the loan. Subsequent decreases to the expected cash flows require the Company to evaluate the need for an allowance for loan losses on these loans. Subsequent improvements in expected cash flows result in the reversal of a corresponding amount of the non-accretable discount which the Company then reclassifies as an accretable discount that is recognized into interest income over the remaining life of the loans using the interest method.
	Acquired loans that met the criteria for non-accrual of interest prior to acquisition may be considered performing upon acquisition, or in the future, regardless of whether the customer is contractually delinquent, if the Company can reasonably estimate the timing and amount of the expected cash flows on such loans and if the Company expects to fully collect the new carrying value of the loans. As such, the Company may no longer consider the loan to be non-accrual or non-performing and may accrue interest on these loans, including the impact of any accretable discount. For acquired loans that are not deemed impaired at acquisition, credit discounts representing the principal losses expected over the life of the loan are a component of the initial fair value and amortized over the life of the asset. Subsequent to the acquisition date, the methods utilized to estimate the required allowance for loan losses for these loans is similar to originated loans, however, the Company records a provision for loan losses only when the required allowance exceeds any remaining pooled discounts for loans evaluated collectively for impairment.
	Allowance for Loan Losses
	The allowance for credit losses consists of the allowance for loan losses and the reserve for unfunded lending commitments. The allowance for loan losses represents management’s estimate of losses inherent in the loan portfolio as of the balance sheet date and is recorded as a reduction to loans. The reserve for unfunded lending commitments, totaling $35 thousand, represents management’s estimate of losses inherent in its unfunded loan commitments and is recorded in other liabilities on the consolidated balance sheet. The allowance for loan losses is increased by the provision for loan losses, and decreased by charge-offs, net of recoveries. Loans deemed to be uncollectible are charged against the allowance for loan losses, and subsequent recoveries, if any, are credited to the allowance. All, or part, of the principal balance of loans receivable are charged off to the allowance as soon as it is determined that the repayment of all, or part, of the principal balance is highly unlikely. Because all identified losses are immediately charged off, no portion of the allowance for loan losses is restricted to any individual loan or groups of loans, and the entire allowance is available to absorb any and all loan losses.
	The allowance for loan losses is maintained at a level considered adequate to provide for losses that can be reasonably anticipated. Management performs a quarterly evaluation of the adequacy of the allowance. 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. This evaluation is inherently subjective as it requires material estimates that may be susceptible to significant revision as more information becomes available.
	The allowance consists of specific, general and unallocated components. The specific component relates to loans that are classified as impaired. For loans that are classified as impaired, an allowance is established when the discounted cash flows (or collateral value or observable market price) of the impaired loan is lower than the carrying value of that loan. The general component covers pools of loans by loan class including commercial loans not considered impaired, as well as smaller balance homogeneous loans, such as residential real estate, home equity and other consumer loans. These pools of loans are evaluated for loss exposure based upon historical loss rates for each of these categories of loans, adjusted for qualitative factors. These qualitative risk factors include:
		1	Lending policies and procedures, including underwriting standards and collection, charge-off, and recovery practices.
		2	National, regional, and local economic and business conditions as well as the condition of various market segments, including the value of underlying collateral for collateral dependent loans.
		3	Nature and volume of the portfolio and terms of loans.
		4	Management team with experience, depth, and knowledge in banking and in many areas of lending. Each contributes to the sound credit culture and control within the Company.
		5	Volume and severity of past due, classified and nonaccrual loans as well as other loan modifications.
		6	The Company engages a third party to perform an independent review of the loan portfolio as a measure for quality and consistency in credit evaluation and credit decisions.
		7	Existence and effect of any concentrations of credit and changes in the level of such concentrations.
		8	Effect of external factors, such as competition and legal and regulatory requirements.
	Each factor is assigned a value to reflect improving, stable or declining conditions based on management’s best judgment using relevant information available at the time of the evaluation. Adjustments to the factors are supported through documentation of changes in conditions in a narrative accompanying the allowance for loan loss calculation.
	A majority of the Company’s loans are to business owners of many types. The Company makes commercial loans for real estate development and other business purposes required by our customers.
	The Company’s credit policies determine advance rates against the different forms of collateral that can be pledged against commercial loans. Typically, the majority of loans will be limited to a percentage of their underlying collateral values such as real estate values, equipment, eligible accounts receivable and inventory. Individual loan advance rates may be higher or lower depending upon the financial strength of the borrower and/or term of the loan. The assets financed through commercial loans are used within the business for its ongoing operation. Repayment of these kinds of loans generally comes from the cash flow of the business or the ongoing conversions of assets. Commercial real estate loans include long-term loans financing commercial properties. Repayment of this kind of loan is dependent upon either the ongoing cash flow of the borrowing entity or the resale of or lease of the subject property. Commercial real estate loans typically require a loan to value ratio of not greater than 80% and vary in terms.
	Residential mortgages and home equity loans are secured by the borrower’s residential real estate in either a first or second lien position. Residential mortgages and home equity loans have varying loan rates depending on the financial condition of the borrower and the loan to value ratio. Residential mortgages have amortizations up to 30 years and home equity loans have maturities up to 10 years.
	Other consumer loans include installment loans, car loans, and overdraft lines of credit. The majority of these loans are secured.
	An unallocated component is maintained to cover uncertainties that could affect management’s estimate of probable losses. The unallocated component of the allowance reflects the margin of imprecision inherent in the underlying assumptions used in the methodologies for estimating specific and general losses in the portfolio.
	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 payment status, collateral value and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls 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, the borrower’s prior payment record and the amount of the shortfall in relation to the principal and interest owed. Impairment is measured on a loan by loan basis for commercial and industrial loans, commercial real estate loans and commercial construction loans by either the present value of expected future cash flows discounted at the loan’s effective interest rate or the fair value of the collateral if the loan is collateral dependent.
	An allowance for loan losses is established for an impaired loan if its carrying value exceeds its estimated fair value. The estimated fair values of substantially all of the Company’s impaired loans are measured based on the estimated fair value of the loan’s collateral.
	For commercial loans secured by real estate, estimated fair values are determined primarily through third-party appraisals. When a real estate secured loan becomes impaired, a decision is made regarding whether an updated certified appraisal of the real estate is necessary. This decision is based on various considerations, including the age of the most recent appraisal, the loan-to-value ratio based on the original appraisal and the condition of the property. Appraised values may be discounted to arrive at the estimated selling price of the collateral, which is considered to be the estimated fair value. The discounts also include estimated costs to sell the property.
	For commercial and industrial loans secured by non-real estate collateral, such as accounts receivable, inventory and equipment, estimated fair values are determined based on the borrower’s financial statements, inventory reports, accounts receivable aging or equipment appraisals or invoices. Indications of value from these sources are generally discounted based on the age of the financial information or the quality of the assets.
	Large groups of smaller balance homogeneous loans are collectively evaluated for impairment. Accordingly, the Company does not separately identify individual residential mortgage loans, home equity loans and other consumer loans for impairment disclosures, unless such loans are the subject of a troubled debt restructuring agreement.
	Acquired loans are recorded at acquisition date at their acquisition date fair values, and therefore, are excluded from the calculation of loan loss reserves as of the acquisition date. To the extent there is a decrease in the present value of cash flows expected from the acquired impaired loans after the date of acquisition, the Company records a provision for potential losses. During the three months ended March 31, 2014, the Company recorded a provision for loan losses totaling $92 thousand for acquired impaired loans. There was no provision recorded for loan losses for acquired impaired loans for the three months ended March 31, 2013.
	For acquired loans that are not deemed impaired at acquisition, credit discounts representing principal losses expected over the life of the loan are a component of the initial fair value. Subsequent to the acquisition date, the methods used to estimate the required allowance for loan losses for these loans is similar to originated loans, however, the Company records a provision for loan losses only when the required allowance exceeds any remaining unamortized general credit fair value adjustment for loans evaluated collectively for impairment.
	The allowance calculation methodology includes further segregation of loan classes into risk rating categories. The borrower’s overall financial condition, repayment sources, guarantors and value of collateral, if appropriate, are evaluated annually for commercial loans or when credit deficiencies arise, such as delinquent loan payments, for commercial and consumer loans. Credit quality risk ratings include regulatory classifications of special mention, substandard, doubtful and loss. Loans criticized special mention have potential weaknesses that deserve management’s close attention. If uncorrected, the potential weaknesses may result in deterioration of the repayment prospects. Loans classified substandard have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They include loans that are inadequately protected by the current sound net worth and paying capacity of the obligor or of the collateral pledged, if any. Loans classified doubtful have all the weaknesses inherent in loans classified substandard with the added characteristic that collection or liquidation in full, on the basis of current conditions and facts, is highly improbable. Loans classified as a loss are considered uncollectible and are charged to the allowance for loan losses. Loans not classified are rated pass.
	In addition, Federal regulatory agencies, as an integral part of their examination process, periodically review the Company’s allowance for loan losses and may require the Company to recognize additions to the allowance based on their judgments about information available to them at the time of their examination, which may not be currently available to management. Based on management’s comprehensive analysis of the loan portfolio, management believes the current level of the allowance for loan losses is adequate.
	Comprehensive Income (Loss)
	Accounting principles generally accepted in the United States of America require that recognized revenue, expenses, gains and losses be included in net income. Although certain changes in assets and liabilities are reported as a separate component of the shareholders’ equity section of the balance sheet, such items, along with net income, are components of total comprehensive income (loss). The Consolidated Statements of Comprehensive Income do not include the effects of income taxes due to the full valuation allowance on deferred tax assets as of March 31, 2014 and 2013, respectively.

Merger with Affinity Bancorp, Inc.	3 Months Ended

Business Combinations [Abstract]	'
Merger with Affinity Bancorp, Inc.	'
	Note 2—Merger with Affinity Bancorp, Inc.
	On February 28, 2013, First Priority and Affinity Bancorp, Inc. completed a merger, pursuant to a definitive merger agreement dated May 23, 2012, whereby the companies agreed to merge their respective holding companies and bank subsidiaries. Under the terms of the merger agreement, shareholders of Affinity received 0.9813 newly issued shares of First Priority in exchange for each Affinity share. A total of 1,933,665 shares of First Priority common stock were issued in connection with the merger. The combination created a full-service community bank with ten offices serving the Berks, Bucks, Chester, and Montgomery County markets. The Company is headquartered in Malvern, PA.
	The merger is being accounted for using acquisition accounting, which requires the Company to allocate the total consideration transferred to the assets acquired and liabilities assumed, based on their respective fair values at the merger date, with any remaining excess consideration being recorded as goodwill. The fair value of total assets acquired as a result of the merger totaled $174.4 million, which consisted of $77.4 million in loans, $33.3 million in securities available for sale, $24.4 million in cash and due from banks and $38.7 million in other assets, of which $33.6 million was related to receivables for investment securities sold prior to the merger, pending settlement. The transaction also resulted in a core deposit intangible asset of $582 thousand and goodwill of $1.5 million. The fair value of liabilities assumed aggregated $165.7 million, including $150.9 million of deposits and $14.4 million in long-term borrowings, of which the borrowings were subsequently paid off in the first quarter of 2013. The transaction added $10.1 million to First Priority’s equity based on the fair value of stock issued in the merger. The results of Affinity’s operations have been included in the Company’s consolidated financial statements prospectively from the date of the merger.

	The acquired assets and assumed liabilities were measured at estimated fair values. In many cases, determining the fair value of the acquired assets and assumed liabilities required First Priority to estimate cash flows expected to result from those assets and liabilities and to discount those cash flows at appropriate rates of interest, which required the utilization of significant estimates and judgment in accounting for the merger.
	The estimated fair values of cash and due from banks, other assets and other liabilities approximate their stated value. The estimated fair values of the investment securities available for sale were calculated primarily using level 2 inputs. The prices for these instruments are obtained through an independent pricing service and are derived from market quotations and matrix pricing. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the bond’s terms and conditions, among other things. Management reviewed the data and assumptions used in pricing the securities to ensure the highest level of significant inputs are derived from market observable data.
	Real estate acquired through foreclosure, included in other assets, was primarily valued based on estimated or appraised collateral values.
	The most significant fair value determination related to the valuation of acquired loans. Management measured loan fair values based on loan file reviews (including borrower financial statements or tax returns), appraised collateral values, expected cash flows and historical loss factors. The business combination resulted in the acquisition of loans with and without evidence of credit quality deterioration.
	Affinity’s loans without evidence of credit deterioration were fair valued by discounting both expected principal and interest cash flows using an observable discount rate for similar instruments that a market participant would consider in determining fair value. Additionally, consideration was given to management’s best estimates of default rates and payment speeds. At acquisition, Affinity’s loan portfolio without evidence of deterioration was recorded at a current fair value of $74.6 million. The Company utilized an interest rate loan fair value analysis, which resulted in a positive fair value adjustment of $1.6 million related to this portion of the acquired loans and a general credit fair value analysis which resulted in an offsetting $1.6 million reduction in the fair value.
	To prepare the interest rate loan fair value analysis loans were assembled into groupings by characteristics such as loan type, term, collateral and rate. Market rates for similar loans were obtained from various external data sources and reviewed by Company management for reasonableness. The average of these rates was used as the fair value interest rate a market participant would utilize.
	A present value approach was utilized to calculate the interest rate fair value adjustment. The general credit risk fair value adjustment was calculated using a two part general credit fair value analysis: (1) expected lifetime losses, using an average of historical losses of the Company, Affinity and peer banks; and (2) an estimated fair value adjustment for qualitative factors related to general economic conditions and the risk related to lack of familiarity with the originator’s underwriting process.
	Affinity’s loans were deemed impaired at the acquisition date if the Company did not expect to receive all contractually required cash flows due to concerns about credit quality. Such loans were recorded at fair value and the difference between contractually required payments at the acquisition date and cash flows expected to be collected was recorded as a nonaccretable difference. Effectively at the acquisition date, the Company recorded $2.8 million of purchased credit-impaired loans subject to a nonaccretable discount difference of $1.6 million. The balance of purchased credit impaired loans at March 31, 2014 was $1.8 million, net of a remaining unamortized non-accretable discount of $1.3 million. The method of measuring carrying value of purchased loans differs from loans originated by the Company (“originated loans”), and as such, the Company identifies purchased loans and purchased loans with a credit quality discount and originated loans at amortized cost. The aggregate expected cash flows less the acquisition date fair value resulted in an accretable yield amount of $292 thousand, which will be recognized over the life of the loans on a level yield basis as an adjustment to yield.
	The following is a summary of the acquired impaired loans resulting from the merger with Affinity (dollars in thousands):
		Acquired Impaired Loans
	Contractually required principal and interest at acquisition	$	5,577
	Contractual cash flows not expected to be collected		2,441
	Expected cash flows at acquisition		3,136
	Interest component of expected cash flows		359
	Basis in acquired loans at acquisition – estimated fair value	$	2,777
	The following table presents the changes in accretable yield related to purchased-credit-impaired loans for the periods ended March 31, 2014 and 2013 (dollars in thousands):
		2014			2013
	Accretable yield balance, beginning of period	$	56		$	—

	Reclassification from nonaccretable difference and disposals, net		13			—
	Accretable yield balance, end of period	$	45		$	243
	The fair value of demand deposits, money market and savings deposits acquired through the merger with Affinity was assumed to be approximately the carrying value as these accounts have no stated maturity and are payable on demand. Certificate of deposit accounts were valued as the present value of the certificates expected contractual payments discounted at market rates for similar certificates.
	Core deposit intangibles (CDI) represent the value assigned to demand, interest checking, money market and savings accounts acquired as part of an acquisition. The CDI value represents the future economic benefit of the potential cost savings from acquiring Core Deposits as part of an acquisition compared to the cost of alternative funding sources and the alternative cost to grow a similar core deposit base. The core deposit intangible of $582 thousand is being amortized over an estimated useful life of approximately 10 years. Amortization expense was $26 thousand and $9 thousand for the three months ended March 31, 2014 and 2013, respectively.
	The following table shows amortization expense for the core deposit intangible for the next 5 years:

	Management used specific market quotations from the FHLB to fair value long-term FHLB advances. These borrowings were subsequently paid off by the Company in the first quarter of 2013 at the recorded fair values.
	In addition, the Company has determined, based on the analysis of available positive and negative evidence, that a valuation allowance should be recorded against deferred taxes of the Company. Therefore, the incremental net deferred tax assets resulting from the merger with Affinity, totaling $1.8 million, were fully reserved by a valuation allowance. Affinity had a Federal net operating loss carryforward (“NOL”) for tax purposes of $1.5 million, or a $497 thousand tax impact at the statutory federal income tax rate of 34%, which is subject to certain limitations and expires in 2032 if not fully utilized. The $497 thousand deferred tax asset related to the NOL is included in the $1.8 million net deferred tax asset discussed above.
	In connection with the Affinity acquisition, First Priority incurred merger-related expenses in regards to professional fees, occupancy and equipment and other costs of integrating and conforming acquired operations with and into First Priority. Those expenses consisted largely of costs related to professional and consulting services, termination of Affinity’s core system contractual agreement and initial communication expenses to introduce First Priority to its new customers, printing and filing costs of completing the transaction and investment banking charges.

	In January 2014, the FASB issued ASU 2014-04, Receivables (Topic 310): Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure. The ASU clarifies that an in substance repossession or foreclosure occurs upon either the creditor obtaining legal title to the residential real estate property or the borrower conveying all interest in the residential real estate property to the creditor to satisfy that loan through completion of a deed in lieu of foreclosure or through a similar legal agreement. The amendments are effective for annual periods, and interim reporting periods within those annual periods, beginning after December 15, 2014. The amendments may be adopted using either a modified retrospective transition method or a prospective transition method. Early adoption is permitted. Management does not believe the amendments will have a material impact on the Company’s Consolidated Financial Statements.

Earnings (Loss) Per Common Share	'
	Note 4—Earnings (Loss) Per Common Share
	Diluted earnings (loss) per common share take into account the potential dilution that could occur if securities or other contracts to issue common stock were exercised and converted into common stock. Proceeds assumed to have been received on such exercise or conversion, are assumed to be used to purchase shares of the Company’s common stock at the average market price during the period, as required by the “treasury stock method” of accounting for common stock equivalents. For purposes of calculating the basic and diluted earnings (loss) per share, the Company’s reported net income (loss) is adjusted for dividends on preferred stock and net accretion/amortization related to the issuance of preferred stock to determine the net income (loss) to common shareholders. For the three months ended March 31, 2014 and 2013, diluted loss per share is the same as basic loss per share, as the effect of any common stock equivalent is antidilutive. For the three months ended March 31, 2014 and March 31, 2013 there were 845 thousand common stock equivalent shares, all of which were antidilutive and therefore, excluded from earnings per share calculations.
	The calculations of basic and diluted earnings (loss) per common share are presented below for the three months ended March 31, 2014 and 2013:

Securities	'
	Note 5—Securities
	Management determines the appropriate classification of debt securities at the time of purchase and re-evaluates such designation as of each balance sheet date. Securities classified as available for sale are those securities that the Company intends to hold for an indefinite period of time, but not necessarily to maturity. Available for sale securities are carried at fair value.
	Securities classified as held to maturity are those debt securities the Company has both the intent and ability to hold to maturity regardless of changes in market conditions, liquidity needs or changes in general economic conditions. These securities are carried at cost adjusted for the amortization of premium and accretion of discount, computed by a method which approximates the interest method over the terms of the securities.
	At March 31, 2014, the Company transferred securities with fair values of $3.7 million consisting of six obligations of states and political subdivisions and one corporate bond from available for sale securities to held to maturity securities. Net unrealized holding losses arising prior to the reclassification date as of March 31, 2014 totaled $137 thousand are reported as a separate line item within accumulated other comprehensive income. The balance of net unrealized holding gains, totaling $151 thousand as of March 31, 2014 and $252 thousand as of December 31, 2013, is being amortized over the remaining life of the related securities as an adjustment of yield in a manner consistent with the accretion of discount on the same transferred debt securities. This will have no impact on the Company’s net income because the amortization of the unrealized holding loss reported in equity will offset the effect on the interest income of the accretion of the discount on these securities.
	The amortized cost, unrealized gains and losses, and the estimated fair value of the Company’s investment securities available for sale and held to maturity are as follows:

As of March 31, 2014, management believes that the estimated fair value of the securities disclosed above is primarily dependent upon the movement in market interest rates particularly given the minimal inherent credit risk associated with the issuers of these securities and that the unrealized losses in these portfolios are not the result of deteriorating credit within any investment category.
Securities issued by states and political subdivisions are all rated investment grade. Each holding is reviewed by quarterly for impairment by management and our investment advisor. All mortgage backed securities and collateralized mortgage obligations are issued by U.S. government sponsored agencies; there are no holdings of private label mortgage backed securities or securities backed by loans classified as “Alt-A” or “Subprime”.
Although the fair value will fluctuate as market interest rates move, management believes that these fair values will recover as the underlying portfolios mature. The Company evaluates a variety of factors in concluding whether securities are other-than-temporarily impaired. These factors include, but are not limited to, the type and purpose of the bond, the underlying rating of the bond issuer, and the presence of credit enhancements (i.e. state guarantees, municipal bond insurance, collateral requirements, etc.). The Company does not intend to sell any of these securities and it is unlikely that it will be required to sell any of these securities before recovery. Management does not believe any individual unrealized loss as of March 31, 2014 represents an other-than-temporary impairment.
There were no realized gains or losses for the three months ended March 31, 2014 and 2013.
Securities with an estimated fair value of $41.8 million and $44.3 million were pledged at March 31, 2014 and December 31, 2013, respectively, to secure public fund deposits. In addition, securities pledged to secure borrowings by the Bank totaled $105 thousand and $106 thousand as of March 31, 2014 and December 31, 2013, respectively.
The amortized cost and fair value of securities as of March 31, 2014 by contractual maturity are shown below. Certain of these investment securities have call features which allow the issuer to call the security prior to its maturity date at the issuer’s discretion.

	The Bank’s loans consist of credits to borrowers spread over a broad range of industrial classifications. The largest concentrations of loans are to lessors of nonresidential buildings and lessors of residential buildings and dwellings. As of March 31, 2014, these loans totaled $64.6 million and $42.0 million, respectively, or 19.0% and 12.3%, respectively, of the total loans outstanding. As of December 31, 2013, these same classifications of loans totaled $64.0 million and $42.7 million, respectively, or 19.1% and 12.7%, respectively, of the total loans outstanding at that time. These credits were subject to normal underwriting standards and did not present more than the normal amount of risk assumed by the Bank’s other lending activities. Management believes this concentration does not pose abnormal risk when compared to the risk it assumes in other types of lending. The Bank has no other concentration of loans which exceeds 10% of total loans.
	The following tables summarize the activity in the allowance for loan losses by loan class for the three months ended March 31, 2014 and 2013:

The Bank’s policy for interest income recognition on nonaccrual loans is to recognize income under the cash basis when the loans are both current and the collateral on the loan is sufficient to cover the outstanding obligation to the Bank. The Bank will not recognize income if these factors do not exist. Interest that would have been accrued on non-accruing loans under the original terms but was not recognized as interest income totaled $73 thousand for the three months ended March 31, 2014 and $62 thousand for the three months ended March 31, 2013, respectively.
The following tables present the classes of the loan portfolio summarized by the aggregate pass rating and the classified ratings of special mention, substandard and doubtful within the Company’s internal risk rating system as of March 31, 2014 and December 31, 2013:

As of March 31, 2014 and December 31, 2013, there were no loans greater than 90 days past due and still accruing.
The Bank may grant a concession or modification for economic or legal reasons related to a borrower’s financial condition that it would not otherwise consider resulting in a modified loan which is then identified as a troubled debt restructuring (“TDR”). The Bank may modify loans through rate reductions, extensions of maturity, interest only payments, or payment modifications to better match the timing of cash flows due under the modified terms with the cash flows from the borrowers’ operations. Loan modifications are intended to minimize the economic loss and to avoid foreclosure or repossession of the collateral. TDRs are considered impaired loans for purposes of calculating the Bank’s allowance for loan losses.
The Bank identifies loans for potential restructure primarily through direct communication with the borrower and evaluation of the borrower’s financial statements, revenue projections, tax returns, and credit reports. Even if the borrower is not presently in default, management will consider the likelihood that cash flow shortages, adverse economic conditions, and negative trends may result in a payment default in the near future.
There were no troubled debt restructurings entered into by the Bank for the three months ended March 31, 2014 and March 31, 2013.
As of March 31, 2014, two loans acquired through the Affinity merger are currently in default and classified as non-accrual consisting of a residential mortgage loan with a current balance of $76 thousand and a commercial mortgage loan with an outstanding balance of $243 thousand.
As of March 31, 2013 two commercial loans classified as troubled debt restructurings with combined outstanding balances as of that date of $82 thousand were in default and remain in default as of the current date and are also classified as non-accrual status. In addition, one home equity line of credit previously classified as a troubled debt restructuring with a pre-modification balance of $695 thousand and a balance as of March 31, 2013 of $246 thousand was in default and classified as non-accrual status; this loan was subsequently charged-off in the second quarter of 2013.
The following table reflects information regarding troubled debt restructuring entered into by the Bank for the year ended December 31, 2013:

As of December 31, 2013 a residential mortgage loan acquired through the Affinity merger is currently in default and classified as non-accrual with a value of $76 thousand. In addition, one home equity line of credit with an outstanding balance of $246 thousand previously classified as troubled debt restructuring was completely charged-off in the second quarter of 2013.
No other TDRs have subsequently defaulted.

	During the initial offering period in 2005, the Company sold 2,107,500 shares of common stock at $10.00 per share, which resulted in net proceeds of $21.0 million. As of February 29, 2008, in connection with the acquisition of Prestige Community Bank First Priority issued an additional 976,137 shares of common stock, resulting in additional equity of $7.4 million.
	On February 28, 2013, in conjunction with the merger with Affinity Bancorp, Inc. and under the terms of the merger agreement, shareholders of Affinity received 0.9813 newly issued shares of First Priority common stock in exchange for each Affinity share. A total of 1,933,665 shares of First Priority common stock were issued; resulting in incremental equity of $10.1 million due to the merger.
	Also, on February 28, 2013 and in conjunction with the merger of Affinity Bancorp, Inc., First Priority issued 1,268,576 shares of common stock at an issuance price of $5.22 per share through a private placement resulting in total proceeds of $6.6 million, net of $50 thousand of related issuance costs.
	Preferred Stock Outstanding
	On February 20, 2009, as part of the Treasury’s TARP Capital Purchase Program, the Company issued (i) 4,579 shares of the Company’s Fixed Rate Cumulative Perpetual Preferred Stock, Series A, $100 par value per share, having a liquidation preference of $1,000 per share (the “Series A Preferred Stock”), and (ii) a warrant (the “Warrant) to purchase, on a net basis, up to 229 shares of the Company’s Fixed Rate Cumulative Perpetual Preferred Stock, Series B, par value $100 per share (the “Series B Preferred Stock”), with an exercise price of $100 per share, for an aggregate purchase price of $4.58 million in cash, less $29 thousand in legal issuance costs. On February 20, 2009, the Treasury immediately exercised the Warrant, on a cashless basis, which resulted in the issuance of the 229 shares of the Series B Preferred Stock. The Series A and Series B Preferred Stock were recorded at fair value and will be amortized to liquidation value over a five year expected life. On December 18, 2009, the Company issued to the U.S. Treasury, (i) 4,596 shares of the Company’s Fixed Rate Cumulative Perpetual Preferred Stock, Series C, $100 par value per share, having a liquidation preference of $1,000 per share (the “Series C Preferred Stock”), for an aggregate purchase price of $4.60 million in cash, less $8 thousand in legal issuance costs.
	On February 8, 2013, the Treasury sold its entire holdings of the Company’s preferred stock to certain qualified or accredited institutional investors.
	The Series A and Series C Preferred Stock will pay cumulative dividends at a rate of 5% per annum for the first five years and 9% per annum thereafter. The Series B Preferred Stock will pay cumulative dividends at a rate of 9% per annum. The Series A, B and C Preferred Stock have no maturity date and rank senior to common stock with respect to dividends and upon liquidation, dissolution, or winding up. The Company may redeem the Series A or Series C Preferred Stock, in whole or in part, at its liquidation preference plus accrued and unpaid dividends. The Company may redeem the Series B Preferred Stock only after all of Series A has been redeemed.

Stock Compensation Program	'
	Note 9—Stock Compensation Program
	In 2005, the Company adopted the 2005 Stock Compensation Program, which was amended at the Company’s annual meeting on April 23, 2009 as the 2009 Stock Compensation Program (the “Program”) and further amended effective March 18, 2010. The Program allows equity benefits to be awarded in the form of Incentive Stock Options, Compensatory Stock Options or Restricted Stock. The Program authorizes the Board of Directors to grant options up to an aggregate maximum of 1,207,957 shares to officers, other employees and directors of the Company, including 382,957 shares which were authorized for grant under this plan as a result of the merger with Affinity. Only employees of the Company will be eligible to receive Incentive Stock Options and such grants are subject to the limitations under Section 422 of the Internal Revenue Code.
	All stock options granted under the Program fully vest in four years from the date of grant (or potentially earlier upon a change of control), excluding options issued in regards to the Company’s Severance Plan which vest only upon change in control, and terminate ten years from the date of the grant. The exercise price of the options granted is the fair value of a share of common stock at the time of the grant, with a minimum exercise price of $10 per share for shares issued prior to March 18, 2010. Effective March 18, 2010, the Company’s stock compensation program was amended to eliminate the minimum exercise price.
	A summary of the status of the Program is presented below for the three months ended March 31, 2014:
						Weighted
						Average
						Exercise
			Shares			Price
	Outstanding at beginning of period			850,649		$	6.96
	Granted during period			—			—
	Forfeited/cancelled during period			(981	)		11.21
	Expired			(4,984	)		6.52
	Outstanding at end of period (1)			844,684		$	6.96
	Exercisable at end of period (1)			303,684		$	9.77
	-1	Included in options outstanding and exercisable at March 31, 2014 are 100,000 organizer options, with an exercise price of $10.00 per share, exchanged as part of the 2008 acquisition of Prestige Community Bank which were issued outside of the Program.
	The weighted average remaining contractual life of all outstanding stock options and exercisable options at March 31, 2014 and 2013 was 6.76 years and 4.50 years, respectively. Options outstanding and exercisable options at March 31, 2014 had no intrinsic value.
	The fair value of each option grant is estimated on the date of grant using the Black-Scholes option-pricing model. There were no options granted in the three months ended March 31, 2014.
	The dividend yield assumption is based on the Company’s history and expectation of dividend payouts. Due to the Company’s lack of sufficient historical exercise data and the limited period of time for which shares have been issued, the “simplified” method is used to determine the expected life of options, calculated as the average of the sum of the vesting term and original contractual term for all periods presented. In valuing Affinity options, an expected life was calculated assuming all options with a three year expiration date expire at expiration date; otherwise, the expected expiration date is the average of three years and the expiration date. The expected volatility percentage is based on the average expected volatility of similar public financial institutions in the Company’s market area. The risk-free interest rates for periods within the contractual life of the awards are based on the U.S. Treasury yield curve in effect at the time of the grant.
	As of March 31, 2014, there was $124 thousand of unrecognized compensation cost related to non-vested stock options granted after January 1, 2007, excluding those stock options issued in conjunction with the Company’s severance plan. That cost is expected to be recognized over a weighted average period of 1.32 years. There was no tax benefit recognized related to this stock-based compensation.
	Restricted Stock grants fully vest three years from the date of grant (or potentially earlier upon a change of control), subject to the recipient remaining an employee of the Company. Upon issuance of the shares, resale of the shares is restricted during the vesting period, during which the shares may not be sold, pledged, or otherwise disposed of. Prior to the vesting date and in the event the recipient terminates association with Company for any reasons other than death, disability or change of control, the recipient forfeits all rights to the shares that would otherwise be issued under the grant. Restricted stock awards granted under the Plan were recorded at the date of the award based on the estimated fair value of the shares. As of March 31, 2014, there was $388 thousand of unrecognized compensation cost related to restricted stock, which will be amortized through December 19, 2016.
	A summary of restricted stock award activity is presented below for the three months ended March 31, 2014:
			Shares
	Outstanding unvested shares at beginning of period			113,774
	Shares Granted during period			—
	Shares Forfeited/cancelled during period			(100	)

Commitments And Contingencies Disclosure [Abstract]	'
Financial Instruments with Off-Balance Sheet Risk	'
	Note 10—Financial Instruments with Off-Balance Sheet Risk
	The Company is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit. Such commitments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the consolidated balance sheet.
	The Company’s exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit is represented by the contractual amount of those instruments. The Company uses the same credit policies in making commitments and conditional obligations as it does for on-balance sheet instruments.
	At March 31, 2014 and December 31, 2013, outstanding commitments to extend credit consisting of total unfunded commitments under lines of credit were $73.5 million and $77.7 million, respectively. In addition, as of March 31, 2014 and December 31, 2013, there were $147 thousand and $1.3 million of performance standby letters of credit outstanding, respectively, and $2.2 million and $1.3 million of financial standby letters of credit, respectively.
	Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements.
	Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. The Bank evaluates each customer’s credit worthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the Bank upon extension of credit, is based on management’s credit evaluation. Collateral held varies but may include personal or commercial real estate, accounts receivable, inventory and equipment.
	In addition, as of March 31, 2014 and December 31, 2013 the Bank pledged $199 thousand of deposit balances at a correspondent bank to support a $199 thousand letter of credit issued by the correspondent on behalf of a customer of the Bank. This transaction is fully secured by the customer through a pledge of the customer’s deposits at the Bank. Also, as of March 31, 2014 and December 31, 2013, the Bank had outstanding a financial standby letter of credit, which was collateralized by a pledge of Bank assets at a correspondent bank totaling $512 thousand.

Note 11—Regulatory Matters

The Bank is subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet the minimum capital requirements can initiate certain mandatory and possibly additional discretionary-actions by regulators that, if undertaken, could have a direct material effect on the Bank’s consolidated financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Bank must meet specific capital guidelines that involve quantitative measures of the Bank’s 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. Prompt corrective action provisions are not applicable to bank holding companies.

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 March 31, 2014, that the Company and the Bank meet all capital adequacy requirements to which it is subject.

The Bank’s capital amounts and ratios at March 31, 2014 and December 31, 2013 are presented below:

First Priority’s ability to pay cash dividends is dependent on receiving cash in the form of dividends from First Priority Bank. However, certain restrictions exist regarding the ability of First Priority Bank to transfer funds to First Priority in the form of cash dividends. All dividends are currently subject to prior approval of the Pennsylvania Department of Banking and Securities and the FDIC and are payable only from the undivided profits of First Priority Bank, with the exception of an exemption enacted by the Pennsylvania Department of Banking and Securities which allows the Bank to pay dividends related to the preferred stock originally issued under the U.S. Department of the Treasury’s Troubled Asset Relief Program—Capital Purchase Program. Additionally, any payment of dividends by First Priority, including dividends on the aforementioned preferred stock, requires prior approval of the Federal Reserve Bank when net income for the past four quarters is not sufficient to fund the dividend payments over that same period or when such payment would negatively impact capital adequacy of the Company.

The Company’s capital amounts and ratios are similar to those of the Bank.

Fair Value Disclosures [Abstract]	'
Fair Value Measurements and Fair Values of Financial Instruments	'
	Note 12—Fair Value Measurements and Fair Values of Financial Instruments
	Management uses its best judgment in estimating the fair value of the Bank’s financial instruments; however, there are inherent weaknesses in any estimation technique. Therefore, for substantially all financial instruments, the fair value estimates herein are not necessarily indicative of the amounts the Company could have realized in a sales transaction on the dates indicated. The estimated fair value amounts have been measured as of March 31, 2014 and December 31, 2013 and have not been re-evaluated or updated for purposes of these financial statements subsequent to those respective dates. As such, the estimated fair values of these financial instruments subsequent to the respective reporting dates may be different than the amounts reported at each period end.
	The Company uses fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. In accordance with FASB ASC Topic 820 – Fair Value Measurements, the fair value of a financial instrument 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. Fair value is best determined based upon quoted market prices. However, in some instances, there are no quoted market prices for the Company’s various financial instruments. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. Accordingly, the fair value estimates may not be realized in an immediate settlement of the instrument.
	The fair value guidance provides a consistent definition of fair value, which focuses on exit price in an orderly transaction (that is, not a forced liquidation or distressed sale) between market participants at the measurement date under current market conditions. If there has been a significant decrease in the volume and level of activity for the asset or liability, a change in valuation technique or the use of multiple valuation techniques may be appropriate. In such instances, determining the price at which willing market participants would transact at the measurement date under current market conditions depends on the facts and circumstances and requires the use of significant judgment. The fair value is a reasonable point within the range that is most representative of fair value under current market conditions.
	FASB ASC Topic 820 establishes a fair value hierarchy that prioritizes the inputs to valuation methods used to measure fair value. The hierarchy gives the highest priority 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). The three levels of the fair value hierarchy under FASB ASC Topic 820 are as follows:
	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).
	An asset’s or liability’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement.
	For financial assets measured at fair value on a recurring basis, the fair value measurements by level within the fair value hierarchy used at March 31, 2014 and December 31, 2013 are as follows:

	Management generally uses a discounted appraisal technique in valuing impaired assets, resulting in the discounting of the collateral values underlying each impaired asset. A discounted tax assessment rate has been applied for smaller assets to determine the discounted collateral value. All impaired loans are classified as Level 3 in the fair value hierarchy. Collateral may be real estate and/or business assets. Impaired loans are reviewed and evaluated on at least a quarterly basis for additional impairment.

-1	Fair Value is generally determined through independent appraisals of the underlying collateral, which include Level 3 inputs that are not identifiable.
-2	Appraisals may be adjusted by management for qualitative factors such as economic conditions and estimated liquidation expenses.
-3	The range and weighted average of qualitative factors such as economic conditions and estimated liquidation expenses are presented as a percent of the appraised value.
Valuation of real estate collateral may be discounted based on the age of the existing appraisal. No discounts are taken for recent appraisals. Valuations related to business assets used as collateral are typically discounted more heavily due to the inherent level of uncertainty in determining the fair value of these types of assets. Liquidation costs relating to these assets are charged to expense.
Repossessed assets consist of personal property, specifically manufactured housing, that has been acquired for debts previously contracted and are included in other assets on the balance sheet. Costs relating to these assets are charged to expense. The Company had $117 thousand and $75 thousand of repossessed assets as of March 31, 2014 and December 31, 2013, respectively.
Other real estate owned consists of properties acquired as a result of accepting a deed in lieu of foreclosure, foreclosure or through other means related to collateral on Bank loans. Costs relating to the development or improvement of assets are capitalized and costs relating to holding the property are charged to expense. At March 31, 2014 and December 31, 2013, the fair value consists of other real estate owned balances of $433 thousand and $524 thousand, respectively, net of valuation allowance of $328 thousand, and $343 thousand, respectively. Fair value is generally determined based upon independent third-party appraisals of the property.
Real estate properties acquired through, or in lieu of, foreclosure are to be sold and are carried at fair value less estimated cost to sell. Fair value is based upon independent market prices or appraised value of the property. These assets are included in Level 3 fair value based upon the lowest level of input that is significant to the fair value measurement.
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 methods and assumptions were used to estimate the fair values of the Company’s financial instruments at March 31, 2014 and December 31, 2013:
Cash and Cash Equivalents
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 obtaining quoted market prices on nationally recognized securities exchanges (Level 1), or 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 quoted prices. For certain securities which are not traded in active markets or are subject to transfer restrictions, valuations are adjusted to reflect illiquidity and/or non-transferability, and such adjustments are generally based on available market evidence (Level 3). In the absence of such evidence, management’s best estimate is used. Management’s best estimate consists of both internal and external support on certain Level 3 investments. Internal cash flow models using a present value formula that includes assumptions market participants would use along with indicative exit pricing obtained from broker/dealers (where available) were used to support fair values of certain Level 3 investments, if applicable.
Loans Receivable
The fair values of loans are estimated using discounted cash flow analyses, using market rates at the balance sheet date that reflect the credit and interest rate-risk inherent in the loans. Projected future cash flows are calculated based upon contractual maturity or call dates, projected repayments and prepayments of principal.
Impaired Loans
Impaired loans are those that are accounted for under FASB ASC Topic 310, “Receivables”, in which the Company has measured impairment generally based on the fair value of the loan’s collateral. Fair value is generally determined based upon independent third- party appraisals of the properties, or discounted cash flows based upon the expected proceeds. These assets are included as Level 3 fair values, based upon the lowest level of input that is significant to the fair value measurements. The fair value of the impaired loans consists of the loan balances, net of any valuation allowance. As of March 31, 2014 the fair value of impaired originated loans consisted of loan balances of $229 thousand, net of valuation allowances of $73 thousand; and loan balances of $1.2 million, net of partial charge-offs of $650 thousand. As of March 31, 2014, the fair value of impaired acquired loans consisted of loan balances of $816 thousand, net of partial charge-offs of $223 thousand. As of December 31, 2013 the fair value of impaired originated loans consisted of loan balances of $744 thousand, net of valuation allowances of $112 thousand; and loan balances of $798 thousand, net of partial charge-offs of $285 thousand. As of December 31, 2013, the fair value of impaired acquired loans consisted of loan balances of $837 thousand, net of partial charge-offs of $188 thousand.
Restricted Investment in Bank Stock
The carrying amount of restricted investment in bank stock approximates fair value, and considers the limited marketability of such securities.
Accrued Interest Receivable and Payable
The carrying amount of accrued interest receivable and accrued interest payable approximates fair value.
Deposit Liabilities
The fair values disclosed for demand deposits (interest and noninterest checking), money market and savings accounts are, by definition, equal to the amount payable on demand at the reporting date (i.e., their carrying amounts). Fair values for fixed-rate certificates of deposit are estimated using a discounted cash flow calculation that applies interest rates currently being offered in the market to the maturities of the time deposits.
Short-Term Borrowings
The carrying amounts of short-term borrowings approximate their fair values.
Long-Term Debt
Fair values of FHLB advances are estimated using discounted cash flow analysis, based on quoted prices for new FHLB advances with similar credit risk characteristics, terms and remaining maturity. These prices obtained from this active market represent a market value that is deemed to represent the transfer price if the liability were assumed by a third party.
Off-Balance Sheet Financial Instruments
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.
At March 31, 2014 and December 31, 2013, the estimated fair values of the Company’s financial instruments were as follows:

Accounting Policies [Abstract]	'
Organization and Nature of Operations	'
	Organization and Nature of Operations
	First Priority Financial Corp.
	First Priority Financial Corp. (“First Priority”, the “Company”) was incorporated under the laws of the Commonwealth of Pennsylvania on February 13, 2007, for the purpose of becoming the holding company of First Priority Bank (the “Bank”) and had no prior operating history. On May 11, 2007, as a result of a reorganization and merger, First Priority Bank became a wholly- owned subsidiary of First Priority.
	On May 23, 2012, First Priority and Affinity Bancorp, Inc. (“Affinity”), the holding company for Affinity Bank of PA (“Affinity Bank”), jointly announced a definitive agreement to merge their respective holding companies and bank subsidiaries. Subsequently, on February 28, 2013, the merger with Affinity was completed. Total assets acquired as a result of the merger were $175.9 million, including $77.4 million in loans, and deposits of $150.9 million. Total incremental equity resulting from the transaction was $10.1 million. Under the terms of the merger agreement, shareholders of Affinity received 0.9813 newly issued shares of First Priority in exchange for each Affinity share. A total of 1,933,665 shares of First Priority common stock were issued in connection with the merger. In conjunction with the completion of the merger, the Company also issued 1,268,576 shares of First Priority common stock as part of a private placement offering that resulted in incremental net equity proceeds of $6.6 million.
	First Priority provides banking services through First Priority Bank and does not engage in any activities other than banking and related activities. As of March 31, 2014, First Priority had total assets of $431.0 million and total shareholders’ equity of $43.6 million.
	First Priority Bank
	First Priority Bank is a state-chartered commercial banking institution which was incorporated under the laws of the Commonwealth of Pennsylvania on May 25, 2005. First Priority Bank’s deposits are insured by the FDIC up to the maximum amount permitted for all banks. As of March 31, 2014, First Priority Bank had total assets of $430.9 million, total loans of $340.1 million, total deposits of $347.4 million and total shareholder’s equity of $42.9 million.
	First Priority Bank engages in a full service commercial and consumer banking business with strong private banking and individual wealth management services. First Priority Bank offers a variety of commercial, private banking and consumer loans, mortgage products and commercial real estate financing. First Priority Bank does not engage in sub-prime lending. The Company’s operations are significantly affected by prevailing economic conditions, competition, and the monetary, fiscal, and regulatory policies of governmental agencies. Lending activities are influenced by a number of factors, including the general credit needs of individuals and small and medium-sized businesses in the Company’s market area, competition, the current regulatory environment, the level of interest rates, and the availability of funds. Deposit flows and costs of funds are influenced by prevailing market rates of interest, competition, account maturities, and the level of personal income and savings in the market area.
	First Priority Bank also offers certain financial planning and investment management services. These investment services are provided by First Priority Financial Services, a Division of First Priority Bank, through an agreement with a third party provider. In addition, various life insurance products are offered through First Priority Bank, and the Bank has also entered into solicitation agreements with several investment advisors to provide portfolio management services to customers of the Bank.
	First Priority Bank currently seeks deposits and commercial and consumer banking relationships through its ten banking offices. The Bank provides deposit products that include checking, money market and savings accounts, and certificates of deposit as well as other deposit services, including cash management and electronic banking products and online account opening capabilities. The Bank obtains funding in the local community by providing excellent service and competitive rates to its customers and utilizes electronic and print media advertising to attract current and potential deposit customers. The Bank also uses brokered certificates of deposit as a cost effective funding alternative.
Basis of Presentation	'
	Basis of Presentation
	The accompanying unaudited consolidated financial statements were prepared in accordance with instructions to Form 10-Q, and therefore, do not include information or all footnotes necessary for a complete presentation of financial position, results of operations and cash flows in conformity with accounting principles generally accepted in the United States (“GAAP”). However, all normal recurring adjustments that, in the opinion of management, are necessary for a fair presentation of these financial statements have been included. These financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto for First Priority Financial Corp. for the year ended December 31, 2013, included in the Company’s Form 10-K filed with the Securities and Exchange Commission on March 28, 2014. The results of interim periods presented are not necessarily indicative of the results that may be expected for the year ending December 31, 2014.
	The accompanying unaudited consolidated financial statements consist of the parent company, First Priority Financial Corp. and its consolidated wholly owned subsidiary, First Priority Bank. The consolidated balance sheets and related statements of income of the Company are substantially the same as the consolidated balance sheets and related statements of income of the Bank. All significant intercompany accounts and transactions have been eliminated in consolidation.
Subsequent Events	'
	Subsequent Events
	The Company has evaluated subsequent events for potential recognition and/or disclosure through the date that these financial statements were issued.
Estimates	'
	Estimates
	The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, stock-based compensation, impairment of goodwill, other than temporary impairment of investment assets, and the valuation of deferred tax assets and other real estate.
Acquired Loans	'
	Acquired Loans
	Acquired loans are initially recorded at their acquisition date fair values. The carryover of allowance for loan losses is prohibited as any credit losses in the loans are included in the determination of the fair value of the loans at the acquisition date. Fair values for acquired loans are based on a discounted cash flow methodology that involves assumptions and judgments as to credit risk, prepayment risk, liquidity risk, default rates, loss severity, payment speeds, collateral values and discount rate.
	Acquired loans that have evidence of deterioration in credit quality since origination and for which it is probable, at acquisition, that the Company will be unable to collect all contractually required payments are accounted for as impaired loans under ASC 310-30. The excess of cash flows expected at acquisition over the estimated fair value is referred to as the accretable discount and is recognized into interest income over the remaining life of the loans. The difference between contractually required payments at acquisition and the cash flows expected to be collected at acquisition is referred to as the non-accretable discount. The non-accretable discount represents estimated future credit losses expected to be incurred over the life of the loan. Subsequent decreases to the expected cash flows require the Company to evaluate the need for an allowance for loan losses on these loans. Subsequent improvements in expected cash flows result in the reversal of a corresponding amount of the non-accretable discount which the Company then reclassifies as an accretable discount that is recognized into interest income over the remaining life of the loans using the interest method.
	Acquired loans that met the criteria for non-accrual of interest prior to acquisition may be considered performing upon acquisition, or in the future, regardless of whether the customer is contractually delinquent, if the Company can reasonably estimate the timing and amount of the expected cash flows on such loans and if the Company expects to fully collect the new carrying value of the loans. As such, the Company may no longer consider the loan to be non-accrual or non-performing and may accrue interest on these loans, including the impact of any accretable discount. For acquired loans that are not deemed impaired at acquisition, credit discounts representing the principal losses expected over the life of the loan are a component of the initial fair value and amortized over the life of the asset. Subsequent to the acquisition date, the methods utilized to estimate the required allowance for loan losses for these loans is similar to originated loans, however, the Company records a provision for loan losses only when the required allowance exceeds any remaining pooled discounts for loans evaluated collectively for impairment.
Allowance for Loan Losses	'
	Allowance for Loan Losses
	The allowance for credit losses consists of the allowance for loan losses and the reserve for unfunded lending commitments. The allowance for loan losses represents management’s estimate of losses inherent in the loan portfolio as of the balance sheet date and is recorded as a reduction to loans. The reserve for unfunded lending commitments, totaling $35 thousand, represents management’s estimate of losses inherent in its unfunded loan commitments and is recorded in other liabilities on the consolidated balance sheet. The allowance for loan losses is increased by the provision for loan losses, and decreased by charge-offs, net of recoveries. Loans deemed to be uncollectible are charged against the allowance for loan losses, and subsequent recoveries, if any, are credited to the allowance. All, or part, of the principal balance of loans receivable are charged off to the allowance as soon as it is determined that the repayment of all, or part, of the principal balance is highly unlikely. Because all identified losses are immediately charged off, no portion of the allowance for loan losses is restricted to any individual loan or groups of loans, and the entire allowance is available to absorb any and all loan losses.
	The allowance for loan losses is maintained at a level considered adequate to provide for losses that can be reasonably anticipated. Management performs a quarterly evaluation of the adequacy of the allowance. 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. This evaluation is inherently subjective as it requires material estimates that may be susceptible to significant revision as more information becomes available.
	The allowance consists of specific, general and unallocated components. The specific component relates to loans that are classified as impaired. For loans that are classified as impaired, an allowance is established when the discounted cash flows (or collateral value or observable market price) of the impaired loan is lower than the carrying value of that loan. The general component covers pools of loans by loan class including commercial loans not considered impaired, as well as smaller balance homogeneous loans, such as residential real estate, home equity and other consumer loans. These pools of loans are evaluated for loss exposure based upon historical loss rates for each of these categories of loans, adjusted for qualitative factors. These qualitative risk factors include:
		1	Lending policies and procedures, including underwriting standards and collection, charge-off, and recovery practices.
		2	National, regional, and local economic and business conditions as well as the condition of various market segments, including the value of underlying collateral for collateral dependent loans.
		3	Nature and volume of the portfolio and terms of loans.
		4	Management team with experience, depth, and knowledge in banking and in many areas of lending. Each contributes to the sound credit culture and control within the Company.
		5	Volume and severity of past due, classified and nonaccrual loans as well as other loan modifications.
		6	The Company engages a third party to perform an independent review of the loan portfolio as a measure for quality and consistency in credit evaluation and credit decisions.
		7	Existence and effect of any concentrations of credit and changes in the level of such concentrations.
		8	Effect of external factors, such as competition and legal and regulatory requirements.
	Each factor is assigned a value to reflect improving, stable or declining conditions based on management’s best judgment using relevant information available at the time of the evaluation. Adjustments to the factors are supported through documentation of changes in conditions in a narrative accompanying the allowance for loan loss calculation.
	A majority of the Company’s loans are to business owners of many types. The Company makes commercial loans for real estate development and other business purposes required by our customers.
	The Company’s credit policies determine advance rates against the different forms of collateral that can be pledged against commercial loans. Typically, the majority of loans will be limited to a percentage of their underlying collateral values such as real estate values, equipment, eligible accounts receivable and inventory. Individual loan advance rates may be higher or lower depending upon the financial strength of the borrower and/or term of the loan. The assets financed through commercial loans are used within the business for its ongoing operation. Repayment of these kinds of loans generally comes from the cash flow of the business or the ongoing conversions of assets. Commercial real estate loans include long-term loans financing commercial properties. Repayment of this kind of loan is dependent upon either the ongoing cash flow of the borrowing entity or the resale of or lease of the subject property. Commercial real estate loans typically require a loan to value ratio of not greater than 80% and vary in terms.
	Residential mortgages and home equity loans are secured by the borrower’s residential real estate in either a first or second lien position. Residential mortgages and home equity loans have varying loan rates depending on the financial condition of the borrower and the loan to value ratio. Residential mortgages have amortizations up to 30 years and home equity loans have maturities up to 10 years.
	Other consumer loans include installment loans, car loans, and overdraft lines of credit. The majority of these loans are secured.
	An unallocated component is maintained to cover uncertainties that could affect management’s estimate of probable losses. The unallocated component of the allowance reflects the margin of imprecision inherent in the underlying assumptions used in the methodologies for estimating specific and general losses in the portfolio.
	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 payment status, collateral value and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls 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, the borrower’s prior payment record and the amount of the shortfall in relation to the principal and interest owed. Impairment is measured on a loan by loan basis for commercial and industrial loans, commercial real estate loans and commercial construction loans by either the present value of expected future cash flows discounted at the loan’s effective interest rate or the fair value of the collateral if the loan is collateral dependent.
	An allowance for loan losses is established for an impaired loan if its carrying value exceeds its estimated fair value. The estimated fair values of substantially all of the Company’s impaired loans are measured based on the estimated fair value of the loan’s collateral.
	For commercial loans secured by real estate, estimated fair values are determined primarily through third-party appraisals. When a real estate secured loan becomes impaired, a decision is made regarding whether an updated certified appraisal of the real estate is necessary. This decision is based on various considerations, including the age of the most recent appraisal, the loan-to-value ratio based on the original appraisal and the condition of the property. Appraised values may be discounted to arrive at the estimated selling price of the collateral, which is considered to be the estimated fair value. The discounts also include estimated costs to sell the property.
	For commercial and industrial loans secured by non-real estate collateral, such as accounts receivable, inventory and equipment, estimated fair values are determined based on the borrower’s financial statements, inventory reports, accounts receivable aging or equipment appraisals or invoices. Indications of value from these sources are generally discounted based on the age of the financial information or the quality of the assets.
	Large groups of smaller balance homogeneous loans are collectively evaluated for impairment. Accordingly, the Company does not separately identify individual residential mortgage loans, home equity loans and other consumer loans for impairment disclosures, unless such loans are the subject of a troubled debt restructuring agreement.
	Acquired loans are recorded at acquisition date at their acquisition date fair values, and therefore, are excluded from the calculation of loan loss reserves as of the acquisition date. To the extent there is a decrease in the present value of cash flows expected from the acquired impaired loans after the date of acquisition, the Company records a provision for potential losses. During the three months ended March 31, 2014, the Company recorded a provision for loan losses totaling $92 thousand for acquired impaired loans. There was no provision recorded for loan losses for acquired impaired loans for the three months ended March 31, 2013.
	For acquired loans that are not deemed impaired at acquisition, credit discounts representing principal losses expected over the life of the loan are a component of the initial fair value. Subsequent to the acquisition date, the methods used to estimate the required allowance for loan losses for these loans is similar to originated loans, however, the Company records a provision for loan losses only when the required allowance exceeds any remaining unamortized general credit fair value adjustment for loans evaluated collectively for impairment.
	The allowance calculation methodology includes further segregation of loan classes into risk rating categories. The borrower’s overall financial condition, repayment sources, guarantors and value of collateral, if appropriate, are evaluated annually for commercial loans or when credit deficiencies arise, such as delinquent loan payments, for commercial and consumer loans. Credit quality risk ratings include regulatory classifications of special mention, substandard, doubtful and loss. Loans criticized special mention have potential weaknesses that deserve management’s close attention. If uncorrected, the potential weaknesses may result in deterioration of the repayment prospects. Loans classified substandard have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They include loans that are inadequately protected by the current sound net worth and paying capacity of the obligor or of the collateral pledged, if any. Loans classified doubtful have all the weaknesses inherent in loans classified substandard with the added characteristic that collection or liquidation in full, on the basis of current conditions and facts, is highly improbable. Loans classified as a loss are considered uncollectible and are charged to the allowance for loan losses. Loans not classified are rated pass.
	In addition, Federal regulatory agencies, as an integral part of their examination process, periodically review the Company’s allowance for loan losses and may require the Company to recognize additions to the allowance based on their judgments about information available to them at the time of their examination, which may not be currently available to management. Based on management’s comprehensive analysis of the loan portfolio, management believes the current level of the allowance for loan losses is adequate.
Comprehensive Income (Loss)	'
	Comprehensive Income (Loss)
	Accounting principles generally accepted in the United States of America require that recognized revenue, expenses, gains and losses be included in net income. Although certain changes in assets and liabilities are reported as a separate component of the shareholders’ equity section of the balance sheet, such items, along with net income, are components of total comprehensive income (loss). The Consolidated Statements of Comprehensive Income do not include the effects of income taxes due to the full valuation allowance on deferred tax assets as of March 31, 2014 and 2013, respectively.

Recently Issued Accounting Standards	'
	In January 2014, the FASB issued ASU 2014-04, Receivables (Topic 310): Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure. The ASU clarifies that an in substance repossession or foreclosure occurs upon either the creditor obtaining legal title to the residential real estate property or the borrower conveying all interest in the residential real estate property to the creditor to satisfy that loan through completion of a deed in lieu of foreclosure or through a similar legal agreement. The amendments are effective for annual periods, and interim reporting periods within those annual periods, beginning after December 15, 2014. The amendments may be adopted using either a modified retrospective transition method or a prospective transition method. Early adoption is permitted. Management does not believe the amendments will have a material impact on the Company’s Consolidated Financial Statements.
