Accounting Policies [Abstract]	'
Summary of Significant Accounting Policies	'
	NOTE 1—SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
	Principles of Consolidation – The consolidated financial statements include the accounts of Pacific Continental Corporation (the “Company”), a bank holding company, and its wholly owned subsidiary, Pacific Continental Bank (the “Bank”) and the Bank’s wholly owned subsidiaries, PCB Service Corporation (which previously owned and operated bank-related real estate but is currently inactive) and PCB Loan Services Corporation (which previously owned and operated certain repossessed or foreclosed collateral but is currently inactive). The Bank provides commercial banking, financing, mortgage lending and other services through fourteen offices located in Western Oregon and Western Washington. The Bank also operates two loan production offices in Tacoma, Washington and Denver, Colorado. All significant intercompany accounts and transactions have been eliminated in consolidation.
	In November 2005, the Company formed a wholly owned Delaware statutory business trust subsidiary, Pacific Continental Corporation Capital Trust (the “Trust”) which issued $8,248 of guaranteed undivided beneficial interests in the Pacific Continental’s Junior Subordinated Deferrable Interest Debentures (“Trust Preferred Securities”). Pacific Continental has not consolidated the accounts of the Trust in its consolidated financial statements in accordance with generally accepted accounting principles, (“GAAP”). As a result, the junior subordinated debentures issued by Pacific Continental to the issuer trust, totaling $8,248, are reflected on Pacific Continental’s consolidated balance sheet at December 31, 2013, under the caption “Junior Subordinated Debentures.” Pacific Continental also recognized its $248 investment in the Trust, which is recorded among “Other Assets” in its consolidated balance sheet at December 31, 2013.
	Use of 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. The most significant estimations made by management involve fair value calculations pertaining to financial assets and liabilities, the calculation of the allowance for loan losses, and the impairment assessment for goodwill.
	Cash and Cash Equivalents – For purposes of reporting cash flows, cash and cash equivalents includes cash on hand, amounts due from or deposited with banks, interest-bearing balances due from banks, and federal funds sold. Generally, federal funds are sold for one-day periods.
	The Company is required to maintain certain reserves with the Federal Reserve Bank as defined by regulation. Such reserves totaling $1,430 and $1,061 were maintained within the Company’s cash balances at December 31, 2013, and 2012, respectively.
	Securities Available-for-Sale – Securities available-for-sale are held for indefinite periods of time and may be sold in response to movements in market interest rates, changes in the maturity or mix of Company assets and liabilities or demand for liquidity. Management determines the appropriate classification of securities at the time of purchase. The Company classified all of its securities as available-for-sale throughout 2013 and 2012.
	Securities classified as available-for-sale are reported at estimated fair value based on available market prices. Net unrealized gains and losses are included in other comprehensive income or loss on an after-tax basis. Impaired securities are assessed quarterly for the presence of other-than-temporary impairment (“OTTI”). OTTI is considered to have occurred, (1) if we intend to sell the security, (2) if it is “more likely than not” we will be required to sell the security before recovery of its amortized cost basis, or (3) the present value of expected cash flows is not sufficient to recover the entire amortized cost basis. The “more likely than not” criteria is a lower threshold than the “probable” criteria used under previous guidance.
	When OTTI is identified, the amount of the impairment is bifurcated into two components: the amount representing credit loss and the amount related to all other factors. The amount representing credit loss is recognized against earnings as a realized loss and the amount representing all other factors is recognized in other comprehensive income as an unrealized loss. Gains and losses on the sale of available-for-sale securities are determined using the specific-identification method. Purchase premiums and discounts are recognized in interest income using the interest method over the terms of the securities. Interest income on securities available-for-sale is included in income using the level yield method.
	Loans Held-for-Sale and Mortgage Banking Activities – The Company historically originated residential mortgage loans for resale in the secondary market. Sales were without recourse and the Company generally did not retain mortgage servicing rights. During first quarter 2012 the company closed the mortgage division and no additional loans held-for-sale were generated during the remainder of 2012 and 2013.
	Loans, Income Recognition, and the Allowance for Loan Losses – Loans are stated at the amount of unpaid principal net of loan premiums or discounts for purchased loans, net deferred loan origination fees, discounts associated with retained portions of loans sold, and an allowance for loan losses. Interest on loans is calculated using the simple-interest method on daily balances of the principal amount outstanding. Loan origination fees, net of origination costs and discounts, are amortized over the lives of the loans as adjustments to yield.
	Nonaccrual Loans
	Accrual of interest is discontinued on contractually delinquent loans when management believes that, after considering economic and business conditions and collection efforts, the borrower’s financial condition is such that collection of principal or interest is doubtful. At a minimum, loans that are past due as to maturity or payment of principal or interest by 90 days or more are placed on nonaccrual status, unless such loans are well-secured and in the process of collection. Interest income is subsequently recognized only to the extent cash payments are received satisfying all delinquent principal and interest amounts, and the prospects for future payments in accordance with the loan agreement appear relatively certain. In accordance with GAAP, payments received on nonaccrual loans are applied to the principal balance and no interest income is recognized.
	Allowance for Loan Losses Methodology
	Management provides for possible loan losses by maintaining an allowance. The allowance for loan losses is established through a provision for loan losses charged to expense. Loans are charged against the allowance when management believes the collection of principal or interest is unlikely. The allowance is an amount that management considers adequate to absorb possible losses on existing loans based on its evaluation of the collectability of those loans and prior loss experience. Management’s evaluations take into consideration such factors as changes in the size and nature of the loan portfolio, the overall portfolio quality, the financial condition of borrowers, the level of nonperforming loans, the Company’s historical loss experience, the estimated value of underlying collateral, and current economic conditions that may affect the borrower’s ability to pay. This evaluation is inherently subjective as it requires estimates that are susceptible to significant subsequent revision as more information becomes available.
	The allowance consists of general, specific and unallocated components. The general component covers all loans not specifically identified for impairment testing. The specific component relates to loans that are individually assessed for impairment. The combined general and specific components of the allowance constitute the Company’s allocated allowance for loan losses. An unallocated allowance may be maintained to provide for credit losses inherent in the loan portfolio that may not have been contemplated in the general risk factors or the specific allowance analysis.
	The Company performs regular credit reviews of the loan portfolio to determine the credit quality of the portfolio and the Company’s adherence to underwriting standards. When loans are originated, they are assigned a risk rating that is reassessed periodically during the terms of the loans through the credit review process. The risk rating categories constitute a primary factor in determining an appropriate amount for the general allowance for loan losses. The general allowance is calculated by applying risk factors to pools of outstanding loans. Risk factors are assigned based on management’s evaluation of the losses inherent within each identified loan category. Loan categories with greater risk of loss are therefore assigned a higher risk factor. The Company’s Asset and Liability Committee (“ALCO”) and Board of Directors are responsible for, among other things, regularly reviewing the allowance for loan losses methodology, including loss factors, and ensuring that it is designed and applied in accordance with generally accepted accounting principles.
	Regular credit reviews of the portfolio are performed to identify loans that are considered potentially impaired. Potentially impaired loans are referred to the ALCO Committee which reviews loans recommended for impairment. A loan is considered impaired when, based on current information and events, the Company is unlikely to collect all principal and interest due according to the terms of the loan agreement. When a loan is deemed to be impaired, the amount of the impairment is measured using discounted cash flows except when the sole remaining source of the repayment is the liquidation of the collateral. In these cases, the current fair value of the collateral, less selling costs is used. Impairment is recognized as a specific component within the allowance for loan losses if the value of the impaired loan is less than the recorded investment in the loan. When the amount of the impairment represents a confirmed loss, it is charged off against the allowance for loan losses. Loans specifically reviewed for impairment are excluded from the general allowance calculation to prevent double-counting the loss exposure. The Company’s ALCO Committee reviews loans recommended for impaired status and those recommended to be removed from impaired status. The Company’s ALCO Committee and Board provide oversight of the allowance for loan losses process and review and approve the allowance methodology on a quarterly basis.
	There have been no significant changes to the Company’s loan loss allowance methodology or policies in the periods presented.
	Charge off Methodology
	When it becomes evident that a loan has a probable loss and is deemed uncollectable, regardless of delinquent status, the loan is charged off. A partial charge-off will occur to the extent of the portion of the loan that is not well secured and is in the process of collection. Additionally, a partial charge-off will occur to the extent of the portion of the loan that is not guaranteed by a federal or state government agency and is in the process of collection. In circumstances whereby it is evident that a government guarantee will not be honored, the loan will be charged-off to the extent of the portion of the loan/lease that is not well secured. Commercial overdrafts will be charged-off within the month the delinquent checking account becomes 90 days delinquent.
	Troubled Debt Restructuring
	Loans are reported as a troubled debt restructuring when the Company grants a concession to a borrower experiencing financial difficulties that it would not otherwise consider. Examples of such concessions include a reduction in the loan rate, forgiveness of principal or accrued interest, extending the maturity date, or providing a lower interest rate than would be normally available for a transaction of similar risk. The Company will undertake a restructuring only when it occurs in ways which improve the likelihood that the credit will be repaid in full under the modified terms and in accordance with a reasonable repayment schedule.
	Off-Balance Sheet Credit Exposure – A reserve for unfunded commitments is maintained at a level that, in the opinion of management, is adequate to absorb probable losses associated with the Company’s commitment to lend funds under existing agreements such as letters or lines of credit. Management determines the adequacy of the reserve for unfunded commitments based upon reviews of individual credit facilities, current economic conditions, the risk characteristics of the various categories of commitments and other relevant factors. These factors include the quality of the current loan portfolio: the trend in the loan portfolio’s risk ratings, current economic conditions, loan concentrations, loan growth rates, past-due and nonperforming trends, evaluation of specific loss estimates for all significant problem loans, historical charge-off and recovery experience, and other pertinent information. The reserve is based on estimates and ultimate losses may vary from the current estimates. These estimates are evaluated on a regular basis and, as adjustments become necessary, they are reported in earnings in the periods in which they become known. Draws on unfunded commitments that are considered uncollectible at the time funds are advanced are charged to the allowance. Provisions for unfunded commitment losses and recoveries on loans commitments previously charged-off are added to the reserve for unfunded commitments, which is included in the Other Liabilities section of the consolidated balance sheets. At December 31, 2013, the reserve for unfunded loan commitments totaled $226 compared to $170 at December 31, 2012.
	Foreclosed Assets – Assets acquired through foreclosure, or deeds in lieu of foreclosure, are initially recorded at fair value less the estimated cost of disposal, at the date of foreclosure. Any excess of the loan’s balance over the fair value of the foreclosed collateral is charged to the allowance for loan losses.
	Improvements to foreclosed assets are capitalized to the extent that the improvements increase the fair value of the assets. Expenditures for routine maintenance and repairs of foreclosed assets are charged to expense as incurred. Management performs periodic valuations of foreclosed assets and may adjust the values to the lower of carrying amount or fair value less the estimated costs to sell. Write downs to net realizable value, if any, and disposition gains or losses are included in noninterest income or expense.
	Federal Home Loan Bank Stock – The investment in Federal Home Loan Bank (“FHLB”) stock is carried at par value, which approximates its fair value. As a member of the FHLB system, the Company is required to maintain a minimum level of investment in FHLB stock based on specific percentages of its outstanding mortgages, total assets or FHLB advances.
	FHLB stock is generally viewed as long-term investment. Accordingly, when evaluating FHLB stock for impairment its value is determined based on the ultimate recoverability of the par value rather than by recognizing temporary declines in value. The determination of whether the decline affects the ultimate recoverability is influenced by criteria such as the following:
		•		The significance of the decline in net assets of the FHLBs as compared to the capital stock amount for the FHLBs and the length of time this situation has persisted.
		•		Commitments by the FHLBs to make payments required by law or regulation and the level of such payments in relation to the operating performance of the FHLBs.
		•		The impact of legislative and regulatory changes on the institution and, accordingly, on the customer base of the FHLBs.
		•		The liquidity position of the FHLBs.
	Property, Plant and Equipment – Property is stated at cost, net of accumulated depreciation and amortization. Additions, betterments and replacements of major units are capitalized. Expenditures for normal maintenance, repairs and replacements of minor units are charged to expense as incurred. Gains or losses realized from sales or retirements are reflected in operations currently.
	Depreciation and amortization is computed by the straight-line method over the estimated useful lives of the assets. Estimated useful lives are 30 to 40 years for buildings, 3 to 10 years for furniture and equipment, and up to the lesser of the useful life or lease term for leasehold improvements.
	Goodwill and Intangible Assets – Intangible assets are comprised of goodwill and other intangibles acquired in business combinations. Goodwill and intangible assets with indefinite useful lives are not amortized. Intangible assets with definite useful lives are amortized to their estimated residual values over their respective estimated useful lives, and also reviewed for impairment. The Company performs a goodwill impairment analysis on an annual basis as of December 31. Additionally, the Company performs a goodwill impairment evaluation on an interim basis when events or circumstances indicate impairment potentially exists. A significant amount of judgment is involved in determining if an indicator of impairment has occurred. Such indicators may include, among others, a significant decline in our expected future cash flows; a sustained, significant decline in our stock price and market capitalization; a significant adverse change in legal factors or in the business climate; adverse action or assessment by a regulator; and unanticipated competition.
	Bank-owned Life Insurance – Bank-owned life insurance is recorded at the estimated cash-surrender value of the policies. Increases in the cash-surrender value are recorded as noninterest income.
	Advertising – Advertising costs are charged to expense during the year in which they are incurred. Advertising expenses were $894, $779, and $720, for the years ended December 31, 2013, 2012 and 2011, respectively.
	Income Taxes – Income taxes are accounted for using the asset and liability method. Deferred tax assets and liabilities are recognized for the expected future tax consequences attributable to differences between financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are calculated using tax rates in effect for the year in which the differences are expected to reverse. Valuation allowances are established to reduce the net carrying amount of deferred tax assets if it is determined to be more likely than not that all or some of the potential deferred tax asset will not be realized.
	The Company follows the provisions of the Financial Accounting Standards Boards’ (“FASB”) ASC 740, “Income Taxes,” relating to accounting for uncertain tax positions. Uncertain tax positions may arise when the Company takes or expects to take a tax position that is ultimately disallowed by the relevant taxing authority. The Company files income tax returns with the Internal Revenue Service and any states in which it has identified that it has nexus. Tax returns for the years subsequent to 2009 remain open to examination by the taxing jurisdictions. Management reviews the Company’s balance sheet, income statement, income tax provision and income tax returns as well as the permanent and temporary adjustments affecting current and deferred income taxes quarterly and assesses whether uncertain tax positions exist. At December 31, 2013, management does not believe that any uncertain tax positions exist, that are not more-likely-than-not, sustainable upon examination. The Company’s policy with respect to interest and penalties ensuing from income tax settlements is to recognize them as noninterest expense.
	Earnings Per Share – Basic earnings per share are computed by dividing net income by the weighted average number of shares outstanding during the period. Diluted earnings per share include the effect of common stock equivalents that would arise from the exercise of stock options discussed in Note 15. Weighted shares outstanding are adjusted retroactively for the effect of stock dividends.
	Weighted average shares outstanding at December 31, are as follows:
			2013		2012		2011
	Basic			17,871,439		18,085,607		18,427,657
	Common stock equivalents attributable to stock-based compensation plans			188,484		152,553		91,890
	Diluted			18,059,923		18,238,160		18,519,547
	Equity grants, including options and Stock Appreciation Rights, for 368,705, 452,480 and 266,859 shares of common stock were excluded from the diluted earnings per share calculation in 2013, 2012 and 2011, respectively, due to their anti-dilutive effect.
	Share-Based Payment Plans – Financial accounting standards require companies to measure and recognize compensation expense for all share-based payments at the grant date based on the fair value of the award, as defined in FASB ASC 718, “Stock Compensation,” and include such costs as an expense in their income statements over the requisite service (vesting) period. The Company estimates the impact of forfeitures based on historical experience with previously granted share-based compensation awards, and considers the impact of the forfeitures when determining the amount of expense to record. The Company generally issues new shares of common stock to satisfy stock option exercises. The Company uses the Black-Scholes option pricing model to measure fair value. No options or Stock Appreciation Rights (“SARs”) were granted in 2012 or 2013. ISOs, nonqualified stock options, restricted stock, restricted stock units, and stock-settled SARs are recognized as equity-based awards and compensation expense is recorded to the income statement over the requisite vesting period based on the grant-date fair value. SARs settled in cash are recognized on the balance sheet as liability-based awards. The grant-date fair value of liability-based awards vesting in the current period, along with the change in fair value of the awards during the period, are recognized as compensation expense and as an adjustment to the recorded liability.
	Fair Value Measurements – Generally accepted accounting principles define fair value as 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. FASB ASC 820, “Fair Value Measurements,” establishes a three-level hierarchy for disclosure of assets and liabilities recorded at fair value. The classification of assets and liabilities within the hierarchy is based on whether the inputs to the valuation methodology used for measurement are observable or unobservable. Observable inputs reflect market-derived or market-based information obtained from independent sources while unobservable inputs reflect our estimates about market data. In general, fair values determined by Level 1 inputs utilize quoted prices for identical assets or liabilities traded in active markets that the Company has the ability to access. Fair values determined by Level 2 inputs utilize inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. Level 2 inputs include quoted prices for similar assets and liabilities in active markets and inputs other than quoted prices that are observable for the asset or liability, such as interest rates and yield curves that are observable at commonly quoted intervals. Level 3 inputs are unobservable inputs for the asset or liability and include situations where there is little, if any, market activity for the asset or liability. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, the level in the fair value hierarchy within which the fair value measurement in its entirety falls has been determined based on the lowest level input that is significant to the fair value measurement in its entirety. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the asset or liability.
	Recently Issued Accounting Pronouncements –
	In July 2012, the FASB issued ASU No. 2012-02, Testing Indefinite-Lived Intangible Assets for Impairment. With this update, a company testing indefinite-lived intangibles for impairment now has the option to assess qualitative factors to determine whether the existence of events and circumstances indicates that it is more likely than not that the indefinite-lived intangible asset is impaired. If, after assessing the totality of events and circumstances, an entity concludes that it is not more likely than not that the indefinite-lived intangible asset is impaired, then the entity is not required to take further action. However, if an entity concludes otherwise, then it is required to determine the fair value of the indefinite-lived intangible asset and perform the quantitative impairment test by comparing the fair value with the carrying amount in accordance with current guidance. An entity also has the option to bypass the qualitative assessment for any indefinite-lived intangible asset in any period and proceed directly to performing the quantitative impairment test. An entity will be able to resume performing the qualitative assessment in any subsequent period. The amendments are effective for annual and interim goodwill impairment tests performed for fiscal years beginning after September 15, 2012. The adoption of this ASU is not expected to have a material impact on the Company’s consolidated financial statements.
	In February 2013, the FASB issued ASU No. 2013-02, Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income. The Update requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component and to present either on the face of the statement where net income is presented, or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income, but only if the amount reclassified is required to be reclassified to net income in its entirety in the same reporting period. The amendments are effective for annual and interim reporting periods beginning on or after December 15, 2013. The Company is currently in the process of evaluating the ASU but does not expect it will have a material impact on the Company’s consolidated financial statements.
	In July 2013, the FASB issued ASU No. 2013-10, Inclusion of the Fed Funds Effective Swap Rate (or Overnight Index Swap Rate) as a Benchmark Interest Rate for Hedge Accounting Purposes . ASU No. 2013-10 permits the use of the Fed Funds Effective Swap Rate (OIS) to be used as a U.S. benchmark interest rate for hedge account purposes. The amendment is effective prospectively for qualifying new or redesiginated hedging relationships entered into on or after July 17, 2013. The adoption of ASU No. 2013-10 did not have a material impact on the Company’s consolidated financial statements.
	In July 2013, the FASB issued ASU No. 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists. ASU No. 2013-11 requires an entity to present an unrecognized tax benefit, or a portion of an unrecognized tax benefit, as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward, except to the extent a net operating loss carryforward, a similar tax loss, or a tax credit carryforward is not available at the reporting date under the tax law of the applicable jurisdiction to settle any additional income taxes that would result from the disallowance of a tax position or the tax law of the applicable jurisdiction does not require the entity to use, and the entity does not intend to use, the deferred tax asset for such purpose, the unrecognized tax benefit should be presented in the financial statements as a liability and should not be combined with deferred tax assets. No new recurring disclosures are required. The amendments are effective for annual and interim reporting periods beginning on or after December 15, 2013 and are to be applied prospectively to all unrecognized tax benefits that exist at the effective date. Retrospective application is permitted. The adoption of ASU No. 2013-11 is not expected to have a material impact on the Company’s consolidated financial statements.
	In January 2014, the FASB issued ASU No. 2014-01, Accounting for Investments in Qualified Affordable Housing Projects. ASU 2014-04 permit an entity to make an accounting policy election to account for their investments in qualified affordable housing projects using the proportional amortization method if certain conditions are met. Under the proportional amortization method, an entity amortizes the initial cost of the investment in proportion to the tax credits and other tax benefits received and recognize the net investment performance in the income statement as a component of income tax expense (benefit). The amendments are effective for annual and interim reporting periods beginning on or after December 15, 2014 and should be applied prospectively. The Company is currently reviewing the requirements of ASU No. 2014-01, but does not expect the ASU to have a material impact on the Company’s consolidated financial statements.
	In January 2014, the FASB issued ASU No. 2014-04, Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon foreclosure. ASU 2014-04 clarifies that an in substance repossession or foreclosure occurs, and a creditor is considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan, upon either (1) the creditor obtaining legal title to the residential real estate property upon completion of a foreclosure or (2) the borrower conveying all interest in the residential real estate property to the creditor to satisfy that loan through completion of a deed in lieu of foreclosure or through a similar legal agreement. Additionally, the amendments require interim and annual disclosure of both (1) the amount of foreclosed residential real estate property held by the creditor and (2) the recorded investment in consumer mortgage loans collateralized by residential real estate property that are in the process of foreclosure according to local requirements of the applicable jurisdiction. The amendments are effective for annual and interim reporting periods beginning on or after December 15, 2014 and can be applied with a modified retrospective transition method or prospectively. The adoption of ASU No. 2014-04 is not expected to have a material impact on the Company’s consolidated financial statements.
	Subsequent events – The Company has evaluated events and transactions subsequent to December 31, 2013 for potential recognition or disclosure.
	Reclassifications – Certain amounts contained in the 2012 and 2011 consolidated financial statements have been reclassified where appropriate to conform to the financial statement presentation used in 2013. These reclassifications had no effect on previously reported net income.

	At December 31, 2013, unrealized losses exist on certain securities classified as obligations of states and political subdivisions, mortgage-backed securities, and private-label mortgage-backed securities. The unrealized losses on securities that are obligations of states and political subdivision are deemed to be temporary. Additionally, the unrealized losses on agency mortgage-backed securities are deemed to be temporary, as they continue to perform adequately and are backed by various government-sponsored enterprises (“GSEs”). These decreases in fair value are associated with the changes in market interest rates or the widening of market spreads subsequent to the initial purchase of the securities, and not due to concerns regarding the underlying credit of the issuers or the underlying collateral. The decline in value of these securities has resulted from current economic conditions. Although yields on these securities may be below market rates during the period, no loss of principal is expected.
	At December 31, 2013, of the 445 investment securities held, there were 187 investment securities in unrealized loss positions. The unrealized loss associated with the investments of $35,809 in a continuous unrealized loss position for twelve months or longer was $947, of which $201 is related to private-label mortgage-backed securities, and $619 is related to mortgage-backed securities. The Company has no current intent, nor is it more likely than not, that it will be required to sell these securities before the recovery of carrying value.
	During the fourth quarter 2013 management reviewed all of its private-label mortgage-backed securities for the presence of other-than-temporary impairment (“OTTI”). Management’s evaluation included the use of independently-generated third-party credit surveillance reports that analyze the loans underlying each security. These reports include estimates of default rates and severities, life collateral loss rates, and static voluntary prepayment assumptions to generate estimated cash flows at the individual security level. Additionally, management considered factors such as downgraded credit ratings, severity and duration of the impairments, the stability of the issuers, and any discounts paid when the securities were purchased. During the fourth quarter 2013, management booked an impairment of $8 on one of its private-label mortgage-backed securities. Management has considered all available information related to the collectability of the impaired investment securities and believes that the estimated credit loss is appropriate.
	Following is a tabular roll-forward of the amount of credit-related OTTI recognized in earnings during 2013, 2012 and 2011:
		December 31,
		2013		2012		2011

	At December 31, 2013, seven of the Company’s private-label mortgage-backed securities with an amortized cost of $2,593 were classified as substandard as their ratings were below investment grade. Securities with an amortized cost of $3,281 and $3,644 were classified as substandard at December 31, 2012, and December 31, 2011, respectively.
	The projected average life of the securities portfolio is 4.2 years and its modified duration is 3.8 years.

	At December 31, 2012, of the 450 investment securities held, there were 20 investment securities in unrealized loss positions. The unrealized loss associated with the investments of $19,851 in a continuous unrealized loss position for twelve months or longer was $604, of which $435 was related to private-label mortgage backed securities, and $169 was related to mortgage-backed securities.

Loans, Allowance for Loan Losses, and Credit Quality Indicators	'
	NOTE 3—LOANS, ALLOWANCE FOR LOAN LOSSES, AND CREDIT QUALITY INDICATORS
	Loans are stated at the amount of unpaid principal net of loan premiums or discounts for purchased loans, net deferred loan origination fees, discounts associated with retained portions of loans sold, and an allowance for loan losses. Interest on loans is calculated using the simple-interest method on daily balances of the principal amount outstanding. Loan origination fees, net of origination costs and discounts, are amortized over the lives of the loans as adjustments to yield.
	Major classifications of loans, including loans held-for-sale, at December 31 are as follows:
			December 31,			% of gross			December 31,			% of gross
			2013			loans			2012			loans
	Real estate secured loans:
	Permanent Loans:

	At December 31, 2013, outstanding loans to dental professionals totaled $307,268 and represented 30.89% of total outstanding loans compared to dental professional loans of $270,782 or 31.08% of total loans at December 31, 2012. Additional information about the Company’s dental portfolio can be found in Item 8, Note 4 of the Notes to Consolidated Financial Statements. There are no other industry concentrations in excess of 10.00% of the total loan portfolio. However, as of December 31, 2013, approximately 60.38% of the Company’s loan portfolio was collateralized by real estate and is, therefore, susceptible to changes in local market conditions. While appropriate action is taken to manage identified concentration risks, management believes that the loan portfolio is well diversified by geographic location and among industry groups.
	Acquired Loans
	On February 1, 2013, the Bank acquired all of the assets and liabilities of Century Bank of Eugene, Oregon. The transaction has been accounted for under the acquisition method of accounting for cash consideration of $13,398, which included the consideration paid for all common shares and outstanding warrants and options. The assets and liabilities were recorded at their estimated fair values as of the acquisition date. The fair value estimates are considered provisional and are subject to change for up to one year after the closing date of the acquisition.
	Acquired loans presented below at December 31, 2013, and the acquisition date:
			December 31, 2013			February 1, 2013
	Contractually required principal payments		$	44,358		$	65,532
	Purchase adjustment for credit and interest rate			(1,341	)		(2,193	)
	Balance of acquired loans		$	43,017		$	63,339
	The acquisition of Century Bank is not considered significant to the Company’s financial statements, therefore pro forma financial information is not presented.

	The allowance for loan losses is established as an amount that management considers adequate to absorb possible losses on existing loans within the portfolio. The allowance consists of general, specific, and unallocated components. The general component is based upon all loans collectively evaluated for impairment. The specific component is based upon all loans individually evaluated for impairment. The unallocated component represents credit losses inherent in the loan portfolio that may not have been contemplated in the general risk factors or the specific allowance analysis. Loans are charged against the allowance when management believes the collection of principal and interest is unlikely.
	The Company performs regular credit reviews of the loan portfolio to determine the credit quality and adherence to underwriting standards. When loans are originated, they are assigned a risk rating that is reassessed periodically during the term of the loan through the credit review process. The Company’s internal risk rating methodology assigns risk ratings ranging from one to ten, where a higher rating represents higher risk. The ten-point risk rating categories are a primary factor in determining an appropriate amount for the allowance for loan losses.
	Estimated credit losses reflect consideration of all significant factors that affect the collectability of the loan portfolio. The historical loss rate for each group of loans with similar risk characteristics is determined based on the Company’s own loss experience in that group. Historical loss experience and recent trends in losses provides a reasonable starting point for analysis, however they do not by themselves form a sufficient basis to determine the appropriate level for the allowance for loan losses. Qualitative or environmental factors that are likely to cause estimated credit losses to differ from historical losses are also considered including but not limited to:
		•		Changes in international, regional, and local economic and business conditions and developments that affect the collectability of the portfolio, including the condition of various market segments,
		•		Changes in the nature and volume of the portfolio and in the terms of loans,
		•		Changes in the experience, ability, and depth of lending management and other relevant staff,
		•		Changes in the volume and severity of past due loans, the volume of nonaccrual loans, and the volume and severity of adversely classified or graded loans,
		•		Changes in the quality of the institution’s loan review system,
		•		Changes in the value of underlying collateral for collateral-dependent loans,
		•		The existence and effect of any concentrations of credit, and changes in the level of such concentrations,
		•		The effect of other external factors such as competition and legal and regulatory requirements on the level of estimated credit losses in the institution’s existing portfolio,
		•		Changes in lending policies and procedures, including changes in underwriting standards and collection, charge-off, and recovery practices not considered elsewhere in estimating credit losses.
		•		Changes in the current and future US political environment, including debt ceiling negotiations, government shutdown and healthcare reform that may affect national, regional and local economic conditions, taxation, or disruption of national or global financial markets.
	The adequacy of the allowance for loan losses and the reserve for unfunded commitments is determined using a consistent, systematic methodology and is monitored regularly based on management’s evaluation of numerous factors. For each portfolio segment, these factors include:
		•		The quality of the current loan portfolio,
		•		The trend in the migration of the loan portfolio’s risk ratings,
		•		The velocity of migration of losses and potential losses,
	•		Current economic conditions,
	•		Loan concentrations,
	•		Loan growth rates,
	•		Past-due and nonperforming trends,
	•		Evaluation of specific loss estimates for all significant problem loans,
	•		Recovery experience,
	•		Peer comparison loss rates.
During second quarter 2013, after several months of evaluation, the Company changed to full migration analysis from the method of probability of default and loss given default, to determine the appropriate amount of general reserves. The Company believes the change provides a more granular analysis accounting for changes in the composition of the portfolio and credit quality deterioration. This method of analysis involves tracking the loss experience on a rolling population of loans over a period of several quarters and the collection and analysis of historical data to determine what rate of loss the Bank has incurred on similarly criticized loans and how the current portfolio could migrate to loss. The change in methodology did not have a material impact on the allowance for loan losses calculation.

The 2013 ending allowance includes $57 in specific allowance for $10,008 of impaired loans ($8,705 net of government guarantees). At December 31, 2012, the Company had $10,174 of impaired loans ($9,493 net of government guarantees) with a specific allowance of $2 assigned. Management believes that the allowance for loan losses was adequate as of December 31, 2013. However, future loan losses may exceed the levels provided for in the allowance for loan losses and could possibly result in additional charges to the provision for loan losses.
Credit Quality Indicators
The Company uses the following loan grades, which are also often used by regulators when assessing the credit quality of a loan portfolio.
Pass – Credit exposure in this category range between the highest credit quality to average credit quality. Primary repayment sources generate satisfactory debt service coverage under normal conditions. Cash flow from recurring sources is expected to continue to produce adequate debt service capacity. There are many levels of credit quality contained in the pass definition, but none of the loans contained in this category rise to the level of special mention.
Special Mention – A special mention asset has potential weaknesses that deserve management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the asset or in the institution’s credit position at some future date. Special mention assets are not adversely classified and do not expose an institution to sufficient risk to warrant adverse classification. The Bank strictly and carefully employs the FDIC definition in assessing assets that may apply to this category. It is apparent that in many cases asset weaknesses relevant to this definition either, (1) better fit a definition of a “well-defined weakness,” or (2) in our experience ultimately migrate to worse risk grade categories, such as Substandard and Doubtful. Consequently, management elects to downgrade most potential Special Mention credits to Substandard or Doubtful, and therefore adopts a conservative risk grade process in the use of the Special Mention risk grade.
Substandard – A substandard asset is inadequately protected by the current sound worth and paying capacity of the Borrower or of the collateral pledged, if any. Assets so classified must have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. Loans in this category are characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected. Loss potential, while existing in the aggregate amount of substandard assets, does not have to exist in individual assets classified substandard.
Doubtful – An asset classified doubtful has all the weaknesses inherent in one classified substandard with the added characteristic that the weaknesses make collection or liquidation in full on the basis of currently existing facts, conditions, and values, highly questionable and improbable.
Management strives to consistently apply these definitions when allocating its loans by loan grade. The loan portfolio is continuously monitored for changes in credit quality and management takes appropriate action to update the loan risk ratings accordingly. Management has not changed the Company’s policy towards its use of credit quality indicators during the periods reported.

Past Due and Nonaccrual Loans
The Company uses the terms “past due” and “delinquent” interchangeably. Amortizing loans are considered past due or delinquent based upon the number of contractually required payments not made. Delinquency status for all contractually matured loans, commercial and commercial real estate loans with non-monthly amortization, and all other extensions of credit is determined based upon the number of calendar months past due.
The following tables present an aged analysis of past due and nonaccrual loans at December 31, 2013, and December 31, 2012:

Impaired Loans
Regular credit reviews of the portfolio are performed to identify loans that are considered potentially impaired. Potentially impaired loans are referred to the ALCO Committee for review and are included in the specific calculation of allowance for loan losses. A loan is considered impaired when, based on current information and events, the Company is unlikely to collect all principal and interest due according to the terms of the loan agreement. When the amount of the impairment represents a confirmed loss it is charged off against the allowance for loan losses. Impaired loans are often reported net of government guarantees to the extent that the guarantees are expected to be collected. Impaired loans generally include all loans classified as nonaccrual and troubled debt restructurings.
Accrual of interest is discontinued on impaired loans when management believes that, after considering economic and business conditions and collection efforts, the borrower’s financial condition is such that collection of principal or interest is doubtful. Accrued, but uncollected interest is generally reversed when loans are placed on nonaccrual status. Interest income is subsequently recognized only to the extent cash payments are received satisfying all delinquent principal and interest amounts, and the prospects for future payments in accordance with the loan agreement appear relatively certain. In accordance with GAAP, payments received on nonaccrual loans are applied to the principal balance and no interest income is recognized. Interest income may be recognized on impaired loans that are not on nonaccrual status.

The recorded investment in impaired loans, net of government guarantees totaled $8,476 and $9,493 at December 31, 2013, and December 31, 2012, respectively.
Troubled Debt Restructurings
In the normal course of business, the Company may modify the terms of certain loans, attempting to protect as much of its investment as possible. Management evaluates the circumstances surrounding each modification to determine whether it is a troubled debt restructuring (“TDR”). TDRs exist when 1) the restructuring constitutes a concession, and 2) the debtor is experiencing financial difficulties. The Company adopted the amendments of Accounting Standards Update No. 2012-02, “Receivables – A Creditor’s Determination of Whether a Restructuring Is a Troubled Debt Restructuring” during the third quarter 2012. The Update requires retrospective application to the beginning of the annual period of adoption.
The following table displays the Company’s TDRs by class at December 31, 2013, and 2012:
		Troubled Debt Restructurings as of

The recorded investment in TDRs in nonaccrual status totaled $1,597 and $2,336 at December 31, 2013, and December 31, 2012, respectively. The Bank’s policy is that loans placed on non-accrual will typically remain on non-accrual status until all principal and interest payments are brought current and the prospect for future payment in accordance with the loan agreement appear relatively certain. The Bank’s policy generally refers to six months of payment performance as sufficient to warrant a return to accrual status.
For the twelve months ended December 31, 2013, the Company identified 10 TDRs that are newly considered impaired for which impairment was previously measured under the Company’s general loan loss allowance methodology. The total recorded investment in such receivables was $3,130, and the associated allowance for loan losses was $19 at December 31, 2013.
The types of modifications offered can generally be described in the following categories:

Loan Participations and Servicing	'
	NOTE 5 – LOAN PARTICIPATIONS AND SERVICING:
	In the normal course of business the Company may sell portions of loans to other institutions for cash in order to extend its lending capacity or to mitigate risk. These sales are commonly referred to as loan participations. Loan participations are performed without recourse and the participant’s interest is ratably concurrent with that retained by the Company. Cash flows are shared proportionately and neither the Company’s nor the participant’s interest is subordinated. The Company retains servicing rights and manages the client relationships for a reasonable servicing fee. The participated portion of these loans is not included in the accompanying consolidated balance sheets and the servicing component of these transactions are not material to the consolidated financial statements. The Company’s exposure to loss is limited to its retained interest in the loans.
	The following table reflects the amounts of loans participated.

Junior Subordinated Debentures	'
	NOTE 11 – JUNIOR SUBORDINATED DEBENTURES:
	In connection with the November 2005 acquisition of NWB Financial Corporation, the Company formed a wholly owned Delaware statutory business trust subsidiary, Pacific Continental Corporation Capital Trust (the “Trust”), which issued $8,248 of guaranteed undivided beneficial interests in the Company’s Junior Subordinated Deferrable Interest Debentures (“Trust Preferred Securities”). These debentures qualify as Tier 1 capital under Federal Reserve Board guidelines. All of the common securities of the Trust are owned by the Company. The proceeds from the issuance of the common securities and the Trust Preferred Securities were used by the Trust to purchase $8,248 of junior subordinated debentures of the Company. The debentures, which represent the sole asset of the Trust, accrued and paid distributions quarterly at a fixed rate of 6.265% per annum of the stated liquidation value of $1 per capital security. At January 7, 2012, the interest rate changed to a variable rate of three-month LIBOR plus 135 basis points. See note 12 for additional information regarding the interest rate SWAP agreement executed on the debenture in 2013.
	The Company has entered into contractual arrangements which, taken collectively, fully and unconditionally guarantee payment of (1) accrued and unpaid distributions required to be paid on the Trust Preferred Securities, (2) the redemption price with respect to any Trust Preferred Securities called for redemption by the Trust, and (3) payments due upon a voluntary or involuntary dissolution, winding up, or liquidation of the Trust. The Trust Preferred Securities are mandatorily redeemable upon maturity of the debentures on January 7, 2036, or upon earlier redemption as provided in the indenture. The Company has the right to redeem the debentures purchased by the Trust in whole or in part, on or after, January 7, 2012. As specified in the indenture, if the debentures are redeemed prior to maturity, the redemption price will be the principal amount and any accrued interest. For the years ended December 31, 2013, 2012, and 2011, the Company recognized net interest expense of $200, $151, and $136, respectively, related to the Trust Preferred Securities.

Derivative Instruments And Hedging Activities Disclosure [Abstract]	'
Derivative Instruments	'
	NOTE 12 – DERIVATIVE INSTRUMENTS:
	Derivative instruments are entered into primarily as a risk management tool of the Company to help manage its interest rate risk position. Financial derivatives are recorded at fair value as other assets and other liabilities. The accounting for changes in the fair value of a derivative depends on whether it has been designated and qualifies as part of a hedging relationship. For a fair value hedge, changes in the fair value of the derivative instrument and changes in the fair value of the hedged asset or liability are recognized currently in earnings. For a cash flow hedge, changes in the fair value of the derivative instrument, to the extent that it is effective, are recorded in accumulated other comprehensive income and subsequently reclassified to earnings as the hedged transaction impacts net income. Any ineffective portion of a cash flow hedge is recognized currently in earnings.
	During the second quarter 2013, the Company entered into an interest rate swap agreement with an $8,000 notional amount to convert its variable-rate Junior Subordinated Debenture debt into a fixed rate for a term of approximately 7 years at a rate of 2.73%. The derivative is designated as a cash flow hedge. The hedge meets the definition of highly effective and the Company expects the hedge to be highly effective throughout the remaining term of the swap. The fair value of the derivative instrument at December 31, 2013, was a $405 unrealized gain, which is recorded in the other asset section of the balance sheet, net of the tax effect. No gain or loss was recognized in earnings for the twelve months ended December 31, 2013, related to interest rate swaps.
	The Company maintains written documentation for the hedge. This documentation identifies the hedging objective and strategy, the hedging instrument, the instrument being hedged, the reasoning behind the assertion that the hedge is highly effective and the methodology for measuring ongoing hedge effectiveness and ineffectiveness. The Company pledged $400 under collateral arrangements as of April 22, 2013, to satisfy collateral requirements associated with the interest rate swap contract.

If unused the credits will expire in the following years: $218 in 2019, $664 in 2020, $521 in 2021, $261 in 2022, $3 in 2023 and $3 in 2024. It is anticipated that all credits and other deferred asset items will be fully utilized in the normal course of operations and, accordingly, management has not reduced deferred tax assets by a valuation allowance.

Share Based Compensation	'
	NOTE 15 – SHARE-BASED COMPENSATION:
	The Company’s 2006 Stock Option and Equity Compensation Plan (the “2006 SOEC Plan”) authorizes the award of up to 1,550,000 shares in stock-based awards. The awards granted under this plan are service-based and are subject to vesting. The Compensation Committee of the Board of Directors may impose any terms or conditions on the vesting of an award that it determines to be appropriate. Awards granted generally vest over four years and have a maximum life of ten years. Awards may be granted at exercise prices of not less than 100.00% of the fair market value of the Company’s common stock at the grant date.
	Pursuant to the 2006 SOEC Plan, incentive stock options (“ISOs”), nonqualified stock options, restricted stock, restricted stock units (“RSUs”), or stock appreciation rights (“SARs”) may be awarded to attract and retain the best available personnel to the Corporation and its subsidiaries. SARs may be settled in common stock or cash as determined at the date of issuance. Liability-based awards (including all cash-settled SARs) have no impact on the number of shares available to be issued within the plan. Additionally, non-qualified option awards and restricted stock awards may be granted to directors under the terms of this plan.
	Prior to April 2006, incentive stock option (“ISO”) and non-qualified option awards were granted to employees and directors under the Company’s 1999 Employees’ Stock Option Plan and the Company’s 1999 Directors’ Stock Option Plan. The Company has stock options outstanding under both of these plans. Subsequent to the annual shareholders’ meeting in April 2006 all shares available under these plans were deregistered and are no longer available for future grants.

Commitments and Contingencies	'
	NOTE 17 – COMMITMENTS AND CONTINGENCIES:
	In the normal course of business under the provisions of the Company’s investment policy, additional investment securities may be purchased from time to time. Commitments to purchase securities are generally settled within a month and are not associated with repurchase agreements.
	In order to meet the financing needs of its clients, the Company commits to extensions of credit and issues letters of credit. The Company uses the same credit policies in making commitments and conditional obligations as it does for other products. In the event of nonperformance by the client, the Company’s exposure to credit loss is represented by the contractual amount of the instruments. The Company’s collateral policies related to financial instruments with off-balance sheet risk conform to its general underwriting guidelines.
	Commitments to extend credit are agreements to lend to a client as long as there is no violation of any condition established in the contract. Commitments generally have expiration dates or other termination clauses and may require payment of a fee. Since some of the commitments may expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements.
	Letters of credit written are conditional commitments issued by the Company to guarantee the performance of a client to a third-party. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to clients.
	Off-balance sheet instruments at December 31 consist of the following:
		2013		2012
	Commitments to purchase securities	$	1,490	$	216
	Commitments to extend credit (principally variable rate)	$	167,374	$	168,073
	Letters of credit and financial guarantees written	$	1,304	$	832
	The Company has entered into Executive Employment Agreements with two key executive officers. The employment agreements provide for minimum aggregate annual base salaries of $704, plus performance adjustments, life insurance coverage, and other perquisites commonly found in such agreements. The two employment agreements expire in 2014 unless extended or terminated earlier.
	Legal contingencies arise from time-to-time in the normal course of business. Based upon analysis of management and in consultation with the Company’s legal counsel there are no current legal matters which are expected to have a material effect on the Company’s consolidated financial position.

Fair Value	'
	NOTE 18 – FAIR VALUE:
	The following disclosures about fair value of financial instruments are made in accordance with provisions of ASC 825 “Financial Instruments.” The use of different assumptions and estimation methods could have a significant effect on fair value amounts. Accordingly, the estimates of fair value herein are not necessarily indicative of the amounts that might be realized in a current market exchange.
	The estimated fair values of the financial instruments at December 31 are as follows:
			2013						2012
			Carrying						Carrying
			Amount			Fair Value			Amount		Fair Value
	Financial assets:
	Cash and cash equivalents		$	21,108		$	21,108		$	28,701	$	28,701

	Junior subordinated debentures			8,248			2,265			8,248		2,193
	Accrued interest payable			193			193			218		218
	Cash and Cash Equivalents – The carrying amount approximates fair value.
	Securities available-for-sale – Fair value is based on quoted market prices. If a quoted market price is not available, fair value is estimated using quoted market prices for similar securities.
	Accrued Interest receivable – The carrying amounts of accrued interest receivable approximate their fair value.
	Loans – For variable rate loans that reprice frequently and have no significant change in credit risk, fair value is based on carrying values. Fair value of fixed rate loans is estimated by discounting the future cash flows using current rates at which similar loans would be made to borrowers with similar credit ratings and for the same remaining maturities. Fair values for impaired loans are estimated using discounted cash flow analyses or underlying collateral values, where applicable, and consider credit risk.
	Federal Home Loan Bank stock – The carrying amount approximates fair value.
	Bank-owned life insurance – The carrying amount approximates fair value.
	Swap Derivative – Fair value is based on quoted market prices.
	Deposits – Fair value of demand, interest bearing demand and savings deposits is the amount payable on demand at the reporting date. Fair value of time deposits is estimated using the interest rates currently offered for deposits of similar remaining maturities.
	Federal Funds and Overnight Funds Purchased – The carrying amount is a reasonable estimate of fair value because of the short-term nature of these borrowings.
	Federal Home Loan Bank Borrowings – Fair value of Federal Home Loan Bank borrowings is estimated by discounting future cash flows at rates currently available for debt with similar terms and remaining maturities.
	Junior Subordinated Debentures – Fair value of Junior Subordinated Debentures is estimated by discounting future cash flows at rates currently available for debt with similar credit risk, terms and remaining maturities.
	Accrued Interest payable – The carrying amounts of accrued interest payable approximate their fair value
	Off-Balance Sheet Financial Instruments – The carrying amount and fair value are based on fees charged for similar commitments and are not material.
	The Company also adheres to the FASB guidance with regards to ASC 820, “Fair Value Measures.” This guidance defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles, and expands disclosures about fair value measurements. The statement requires fair value measurement disclosure of all assets and liabilities that are carried at fair value on either a recurring or nonrecurring basis. The Company determines fair value based upon quoted prices when available or through the use of alternative approaches, such as matrix or model pricing, when market quotes are not readily accessible or available. The valuation techniques used are based on observable and unobservable inputs. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company’s market assumptions. These two types of inputs create the following fair value hierarchy:
	Level 1 – Quoted prices for identical instruments in active markets.
	Level 2 – Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active or model-derived valuations whose inputs are observable or whose significant value drivers are observable.
	Level 3 – Unobservable inputs are used to measure fair value to the extent that observable inputs are not available. The Company’s own data used to develop unobservable inputs is adjusted for market consideration when reasonably available.
	Financial instruments, measured at fair value, are broken down in the tables below by recurring or nonrecurring measurement status. Recurring assets are initially measured at fair value and are required to be remeasured at fair value in the financial statements at each reporting date. Assets measured on a nonrecurring basis are assets that, due to an event or circumstance, were required to be remeasured at fair value after initial recognition in the financial statements at some time during the reporting period.
	The following table presents information about the level in the fair value hierarchy for the Company’s assets and liabilities not measured at fair value as of December 31, 2013 and 2012:

During 2013 there was a transfer of one security from a level 2 measurement to a level 3 as OTTI was recorded for the first time.
The following is a description of the inputs and valuation methodologies used for assets recorded at fair value on a recurring basis. Fair value for all classes of available-for-sale securities is estimated by obtaining quoted market prices for identical assets, where available. If such prices are not available, fair value is based on independent asset pricing services and models, the inputs of which are market-based or independently sourced market parameters, including, but not limited to, yield curves, interest rates, prepayments, defaults, cumulative loss projections, and cash flows. There have been no significant changes in the valuation techniques during the periods reported.
The following table provides a reconciliation of assets measured at fair value on a recurring basis using unobservable inputs (Level 3) from December 31, 2012, to December 31, 2013:

If such prices are not available, fair value is based on quoted prices for similar instruments or model-derived valuations whose inputs are observable or whose significant value drivers are observable. In instances where quoted prices for identical or similar instruments and observable inputs are not available, unobservable inputs, including the Company’s own data, are used.
The Company utilizes FTN Financial as an independent third-party asset pricing service to estimate fair value on all of its available-for-sale securities. The inputs used to value all securities include benchmark yields, reported trades, broker/dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers, and reference data including market research, market indicators, and industry and economic trends. Additional inputs specific to each asset type are as follows:
	•		Obligations of U.S. government agencies – TRACE reported trades.
	•		Obligations of states and political subdivisions – MSRB reported trades, material event notices, and Municipal Market Data (MMD) benchmark yields.
	•		Private-label mortgage-backed securities – new issue data, monthly payment information, and collateral performance (whole loan collateral).
	•		Mortgage-backed securities – TBA prices and monthly payment information.
Inputs may be prioritized differently on any given day for any security and not all inputs listed are available for use in the evaluation process on any given day for each security evaluation.
The valuation methodology used by asset type includes:
	•		Obligations of U.S. government agencies – security characteristics, defined sector break-down, benchmark yields, applied base spread, yield to maturity (bullet structures), corporate action adjustment, and evaluations based on T+3 settlement.
	•		Obligations of states and political subdivisions – security characteristics, benchmark yields, applied base spread, yield to worst or market convention, ratings updates, prepayment schedules (housing bonds), material event notice adjustments, and evaluations based on T+3 settlement.
	•		Private-label mortgage-backed securities – security characteristics, prepayment speeds, cash flows, TBA, Treasury and swap curves, IO/PO strips or floating indexes, applied base spread, spread adjustments, yield to worst or market convention, ratings updates (whole-loan collateral), and evaluations based on T+0 settlement.
	•		Mortgage-backed securities – security characteristics, TBA, Treasury, or floating index benchmarks, spread to TBA levels, prepayment speeds, applied spreads, and evaluations based on T+0 settlement.
The third-party pricing service follows multiple review processes to assess the available market, credit and deal-level information to support its valuation estimates. If sufficient objectively verifiable information is not available to support a security’s valuation, an alternate independent evaluation source will be used.
The Company’s securities portfolio was valued through its independent third-party pricing service using evaluated pricing models and quoted prices based on market data. For further assurance, the Company’s estimate of fair value was compared to an additional independent third-party estimate at July 31, 2013, and the Company obtained key inputs for a sample of securities across sectors and evaluated those inputs for reasonableness. This analysis was performed at the individual security level and no material variances were noted.
There have been no significant changes in the valuation techniques during the periods reported.

No transfers to or from Level 3 occurred during 2013 or 2012 on assets measured at fair value on a nonrecurring basis.
The following is a description of the inputs and valuation methodologies used for assets recorded at fair value on a nonrecurring basis.
Loans measured for impairment (net of government guarantees and specific reserves) include the estimated fair value of collateral-dependent loans, less collectible government guarantees, as well as certain noncollateral-dependent loans measured for impairment with an allocated specific reserve. When a collateral-dependent loan is identified as impaired, the value of the loan is measured using the current fair value of the collateral less selling costs. The fair value of collateral is generally estimated by obtaining external appraisals which are usually updated every 6 to 12 months based on the nature of the impaired loans. Certain noncollateral-dependent loans measured for impairment with an allocated specific reserve are valued based upon the estimated net realizable value of the loan. If the estimated fair value of the impaired loan, less collectible government guarantees, is less than the recorded investment in the loan, impairment is recognized as a charge-off through the allowance for loan losses. The carrying value of the loan is adjusted to the estimated fair value. The carrying value of loans fully charged off is zero.
Other real estate owned represents real estate which the Company has taken control of in partial or full satisfaction of loans. At the time of foreclosure, other real estate owned is recorded at the lower of the carrying amount of the loan or fair value less costs to sell, which becomes the property’s new basis. Any write downs based on the asset’s fair value at the date of acquisition are charged to the allowance for loan losses. After foreclosure, management periodically orders appraisals or performs valuations to ensure that the real estate is carried at the lower of its new cost basis or fair value, net of estimated costs to sell. Appraisals are generally updated every 6 to 12 months on other real estate owned. Fair value adjustments on other real estate owned are recognized within net loss on real estate owned. The loss represents impairments on other real estate owned for fair value adjustments based on the fair value of the real estate.
There have been no significant changes in the valuation techniques during the periods reported.

Banking And Thrift [Abstract]	'
Regulatory Matters	'
	NOTE 19 – REGULATORY MATTERS:
	The Company and the Bank are subject to the regulations of certain federal and state agencies and receive periodic examinations by those regulatory authorities. In addition, they are subject to various regulatory capital requirements administered by federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory – and possibly additional discretionary – actions by regulators that, if undertaken, could have a direct material effect on the 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 Company and the Bank’s capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings and other factors.
	Quantitative measures established by regulation to ensure capital adequacy require the Company and the Bank to maintain minimum amounts and ratios of Total and Tier 1 capital to risk-weighted assets and of Tier 1 capital to leverage assets. Management believes that, as of December 31, 2013, the Company and the Bank meet all capital adequacy requirements to which they are subject.
	As of December 31, 2013, according to FDIC guidelines, the Bank is considered to be well-capitalized. To be categorized as well-capitalized, the Bank must maintain minimum Total risk-based, Tier 1 risk-based and Tier 1 leverage ratios as set forth in the following table.
	The Company’s and the Bank’s actual capital amounts and ratios are presented in the table below:
		Actual					For Capital					To Be Well

	On July 2, 2013, the federal banking regulators approved the final proposed rules that revise the regulatory capital rules to incorporate certain revisions by the Basel Committee on Banking Supervision to the Basel capital framework (“Basel III”). The phase-in period for the final rules will begin for the Company on January 1, 2015, with full compliance with the final rules entire requirement phased in on January 1, 2019.
	The final rules, among other things, include a new common equity Tier 1 capital (“CET1”) to risk-weighted assets ratio, including a capital conservation buffer, which will gradually increase from 4.50% on January 1, 2015 to 7.00% on January 1, 2019. The final rules also raise the minimum ratio of Tier 1 capital to risk-weighted assets from 4.00% to 6.00% on January 1, 2015 to 8.50% on January 1, 2019, as well as require a minimum leverage ratio of 4.00%.
	Also, under the final rules, trust preferred security debt issuances will be phased out of Tier 1 capital into Tier 2 capital over a 10 year period, except for bank holding companies with less than $15 billion assets as of December 31, 2009 will be allowed to continue to include these issuances in Tier 1 capital, subject to certain restrictions. As the Company had less than $15 billion in assets at December 31, 2009, the Company will be able to continue to include its existing trust preferred securities, less the common stock of the Trusts, in the Company’s Tier 1 capital.

Summary_of_Significant_Account1

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2013
Accounting Policies [Abstract]	'
Principles of Consolidation	'
	Principles of Consolidation – The consolidated financial statements include the accounts of Pacific Continental Corporation (the “Company”), a bank holding company, and its wholly owned subsidiary, Pacific Continental Bank (the “Bank”) and the Bank’s wholly owned subsidiaries, PCB Service Corporation (which previously owned and operated bank-related real estate but is currently inactive) and PCB Loan Services Corporation (which previously owned and operated certain repossessed or foreclosed collateral but is currently inactive). The Bank provides commercial banking, financing, mortgage lending and other services through fourteen offices located in Western Oregon and Western Washington. The Bank also operates two loan production offices in Tacoma, Washington and Denver, Colorado. All significant intercompany accounts and transactions have been eliminated in consolidation.
	In November 2005, the Company formed a wholly owned Delaware statutory business trust subsidiary, Pacific Continental Corporation Capital Trust (the “Trust”) which issued $8,248 of guaranteed undivided beneficial interests in the Pacific Continental’s Junior Subordinated Deferrable Interest Debentures (“Trust Preferred Securities”). Pacific Continental has not consolidated the accounts of the Trust in its consolidated financial statements in accordance with generally accepted accounting principles, (“GAAP”). As a result, the junior subordinated debentures issued by Pacific Continental to the issuer trust, totaling $8,248, are reflected on Pacific Continental’s consolidated balance sheet at December 31, 2013, under the caption “Junior Subordinated Debentures.” Pacific Continental also recognized its $248 investment in the Trust, which is recorded among “Other Assets” in its consolidated balance sheet at December 31, 2013.
Use of Estimates	'
	Use of 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. The most significant estimations made by management involve fair value calculations pertaining to financial assets and liabilities, the calculation of the allowance for loan losses, and the impairment assessment for goodwill.
Cash and Cash Equivalents	'
	Cash and Cash Equivalents – For purposes of reporting cash flows, cash and cash equivalents includes cash on hand, amounts due from or deposited with banks, interest-bearing balances due from banks, and federal funds sold. Generally, federal funds are sold for one-day periods.
	The Company is required to maintain certain reserves with the Federal Reserve Bank as defined by regulation. Such reserves totaling $1,430 and $1,061 were maintained within the Company’s cash balances at December 31, 2013, and 2012, respectively.
Securities Available-for-Sale	'
	Securities Available-for-Sale – Securities available-for-sale are held for indefinite periods of time and may be sold in response to movements in market interest rates, changes in the maturity or mix of Company assets and liabilities or demand for liquidity. Management determines the appropriate classification of securities at the time of purchase. The Company classified all of its securities as available-for-sale throughout 2013 and 2012.
	Securities classified as available-for-sale are reported at estimated fair value based on available market prices. Net unrealized gains and losses are included in other comprehensive income or loss on an after-tax basis. Impaired securities are assessed quarterly for the presence of other-than-temporary impairment (“OTTI”). OTTI is considered to have occurred, (1) if we intend to sell the security, (2) if it is “more likely than not” we will be required to sell the security before recovery of its amortized cost basis, or (3) the present value of expected cash flows is not sufficient to recover the entire amortized cost basis. The “more likely than not” criteria is a lower threshold than the “probable” criteria used under previous guidance.
	When OTTI is identified, the amount of the impairment is bifurcated into two components: the amount representing credit loss and the amount related to all other factors. The amount representing credit loss is recognized against earnings as a realized loss and the amount representing all other factors is recognized in other comprehensive income as an unrealized loss. Gains and losses on the sale of available-for-sale securities are determined using the specific-identification method. Purchase premiums and discounts are recognized in interest income using the interest method over the terms of the securities. Interest income on securities available-for-sale is included in income using the level yield method.
Loans Held-for-Sale and Mortgage Banking Activities	'
	Loans Held-for-Sale and Mortgage Banking Activities – The Company historically originated residential mortgage loans for resale in the secondary market. Sales were without recourse and the Company generally did not retain mortgage servicing rights. During first quarter 2012 the company closed the mortgage division and no additional loans held-for-sale were generated during the remainder of 2012 and 2013.
Loans, Income Recognition, and the Allowance for Loan Losses	'
	Loans, Income Recognition, and the Allowance for Loan Losses – Loans are stated at the amount of unpaid principal net of loan premiums or discounts for purchased loans, net deferred loan origination fees, discounts associated with retained portions of loans sold, and an allowance for loan losses. Interest on loans is calculated using the simple-interest method on daily balances of the principal amount outstanding. Loan origination fees, net of origination costs and discounts, are amortized over the lives of the loans as adjustments to yield.
	Nonaccrual Loans
	Accrual of interest is discontinued on contractually delinquent loans when management believes that, after considering economic and business conditions and collection efforts, the borrower’s financial condition is such that collection of principal or interest is doubtful. At a minimum, loans that are past due as to maturity or payment of principal or interest by 90 days or more are placed on nonaccrual status, unless such loans are well-secured and in the process of collection. Interest income is subsequently recognized only to the extent cash payments are received satisfying all delinquent principal and interest amounts, and the prospects for future payments in accordance with the loan agreement appear relatively certain. In accordance with GAAP, payments received on nonaccrual loans are applied to the principal balance and no interest income is recognized.
	Allowance for Loan Losses Methodology
	Management provides for possible loan losses by maintaining an allowance. The allowance for loan losses is established through a provision for loan losses charged to expense. Loans are charged against the allowance when management believes the collection of principal or interest is unlikely. The allowance is an amount that management considers adequate to absorb possible losses on existing loans based on its evaluation of the collectability of those loans and prior loss experience. Management’s evaluations take into consideration such factors as changes in the size and nature of the loan portfolio, the overall portfolio quality, the financial condition of borrowers, the level of nonperforming loans, the Company’s historical loss experience, the estimated value of underlying collateral, and current economic conditions that may affect the borrower’s ability to pay. This evaluation is inherently subjective as it requires estimates that are susceptible to significant subsequent revision as more information becomes available.
	The allowance consists of general, specific and unallocated components. The general component covers all loans not specifically identified for impairment testing. The specific component relates to loans that are individually assessed for impairment. The combined general and specific components of the allowance constitute the Company’s allocated allowance for loan losses. An unallocated allowance may be maintained to provide for credit losses inherent in the loan portfolio that may not have been contemplated in the general risk factors or the specific allowance analysis.
	The Company performs regular credit reviews of the loan portfolio to determine the credit quality of the portfolio and the Company’s adherence to underwriting standards. When loans are originated, they are assigned a risk rating that is reassessed periodically during the terms of the loans through the credit review process. The risk rating categories constitute a primary factor in determining an appropriate amount for the general allowance for loan losses. The general allowance is calculated by applying risk factors to pools of outstanding loans. Risk factors are assigned based on management’s evaluation of the losses inherent within each identified loan category. Loan categories with greater risk of loss are therefore assigned a higher risk factor. The Company’s Asset and Liability Committee (“ALCO”) and Board of Directors are responsible for, among other things, regularly reviewing the allowance for loan losses methodology, including loss factors, and ensuring that it is designed and applied in accordance with generally accepted accounting principles.
	Regular credit reviews of the portfolio are performed to identify loans that are considered potentially impaired. Potentially impaired loans are referred to the ALCO Committee which reviews loans recommended for impairment. A loan is considered impaired when, based on current information and events, the Company is unlikely to collect all principal and interest due according to the terms of the loan agreement. When a loan is deemed to be impaired, the amount of the impairment is measured using discounted cash flows except when the sole remaining source of the repayment is the liquidation of the collateral. In these cases, the current fair value of the collateral, less selling costs is used. Impairment is recognized as a specific component within the allowance for loan losses if the value of the impaired loan is less than the recorded investment in the loan. When the amount of the impairment represents a confirmed loss, it is charged off against the allowance for loan losses. Loans specifically reviewed for impairment are excluded from the general allowance calculation to prevent double-counting the loss exposure. The Company’s ALCO Committee reviews loans recommended for impaired status and those recommended to be removed from impaired status. The Company’s ALCO Committee and Board provide oversight of the allowance for loan losses process and review and approve the allowance methodology on a quarterly basis.
	There have been no significant changes to the Company’s loan loss allowance methodology or policies in the periods presented.
	Charge off Methodology
	When it becomes evident that a loan has a probable loss and is deemed uncollectable, regardless of delinquent status, the loan is charged off. A partial charge-off will occur to the extent of the portion of the loan that is not well secured and is in the process of collection. Additionally, a partial charge-off will occur to the extent of the portion of the loan that is not guaranteed by a federal or state government agency and is in the process of collection. In circumstances whereby it is evident that a government guarantee will not be honored, the loan will be charged-off to the extent of the portion of the loan/lease that is not well secured. Commercial overdrafts will be charged-off within the month the delinquent checking account becomes 90 days delinquent.
	Troubled Debt Restructuring
	Loans are reported as a troubled debt restructuring when the Company grants a concession to a borrower experiencing financial difficulties that it would not otherwise consider. Examples of such concessions include a reduction in the loan rate, forgiveness of principal or accrued interest, extending the maturity date, or providing a lower interest rate than would be normally available for a transaction of similar risk. The Company will undertake a restructuring only when it occurs in ways which improve the likelihood that the credit will be repaid in full under the modified terms and in accordance with a reasonable repayment schedule.
Off-Balance Sheet Credit Exposure	'
	Off-Balance Sheet Credit Exposure – A reserve for unfunded commitments is maintained at a level that, in the opinion of management, is adequate to absorb probable losses associated with the Company’s commitment to lend funds under existing agreements such as letters or lines of credit. Management determines the adequacy of the reserve for unfunded commitments based upon reviews of individual credit facilities, current economic conditions, the risk characteristics of the various categories of commitments and other relevant factors. These factors include the quality of the current loan portfolio: the trend in the loan portfolio’s risk ratings, current economic conditions, loan concentrations, loan growth rates, past-due and nonperforming trends, evaluation of specific loss estimates for all significant problem loans, historical charge-off and recovery experience, and other pertinent information. The reserve is based on estimates and ultimate losses may vary from the current estimates. These estimates are evaluated on a regular basis and, as adjustments become necessary, they are reported in earnings in the periods in which they become known. Draws on unfunded commitments that are considered uncollectible at the time funds are advanced are charged to the allowance. Provisions for unfunded commitment losses and recoveries on loans commitments previously charged-off are added to the reserve for unfunded commitments, which is included in the Other Liabilities section of the consolidated balance sheets. At December 31, 2013, the reserve for unfunded loan commitments totaled $226 compared to $170 at December 31, 2012.
Foreclosed Assets	'
	Foreclosed Assets – Assets acquired through foreclosure, or deeds in lieu of foreclosure, are initially recorded at fair value less the estimated cost of disposal, at the date of foreclosure. Any excess of the loan’s balance over the fair value of the foreclosed collateral is charged to the allowance for loan losses.
	Improvements to foreclosed assets are capitalized to the extent that the improvements increase the fair value of the assets. Expenditures for routine maintenance and repairs of foreclosed assets are charged to expense as incurred. Management performs periodic valuations of foreclosed assets and may adjust the values to the lower of carrying amount or fair value less the estimated costs to sell. Write downs to net realizable value, if any, and disposition gains or losses are included in noninterest income or expense.
Federal Home Loan Bank Stock	'
	Federal Home Loan Bank Stock – The investment in Federal Home Loan Bank (“FHLB”) stock is carried at par value, which approximates its fair value. As a member of the FHLB system, the Company is required to maintain a minimum level of investment in FHLB stock based on specific percentages of its outstanding mortgages, total assets or FHLB advances.
	FHLB stock is generally viewed as long-term investment. Accordingly, when evaluating FHLB stock for impairment its value is determined based on the ultimate recoverability of the par value rather than by recognizing temporary declines in value. The determination of whether the decline affects the ultimate recoverability is influenced by criteria such as the following:
		•		The significance of the decline in net assets of the FHLBs as compared to the capital stock amount for the FHLBs and the length of time this situation has persisted.
		•		Commitments by the FHLBs to make payments required by law or regulation and the level of such payments in relation to the operating performance of the FHLBs.
		•		The impact of legislative and regulatory changes on the institution and, accordingly, on the customer base of the FHLBs.
		•		The liquidity position of the FHLBs.
Property, Plant and Equipment	'
	Property, Plant and Equipment – Property is stated at cost, net of accumulated depreciation and amortization. Additions, betterments and replacements of major units are capitalized. Expenditures for normal maintenance, repairs and replacements of minor units are charged to expense as incurred. Gains or losses realized from sales or retirements are reflected in operations currently.
	Depreciation and amortization is computed by the straight-line method over the estimated useful lives of the assets. Estimated useful lives are 30 to 40 years for buildings, 3 to 10 years for furniture and equipment, and up to the lesser of the useful life or lease term for leasehold improvements.
Goodwill and Intangible Assets	'
	Goodwill and Intangible Assets – Intangible assets are comprised of goodwill and other intangibles acquired in business combinations. Goodwill and intangible assets with indefinite useful lives are not amortized. Intangible assets with definite useful lives are amortized to their estimated residual values over their respective estimated useful lives, and also reviewed for impairment. The Company performs a goodwill impairment analysis on an annual basis as of December 31. Additionally, the Company performs a goodwill impairment evaluation on an interim basis when events or circumstances indicate impairment potentially exists. A significant amount of judgment is involved in determining if an indicator of impairment has occurred. Such indicators may include, among others, a significant decline in our expected future cash flows; a sustained, significant decline in our stock price and market capitalization; a significant adverse change in legal factors or in the business climate; adverse action or assessment by a regulator; and unanticipated competition.
Bank-owned Life Insurance	'
	Bank-owned Life Insurance – Bank-owned life insurance is recorded at the estimated cash-surrender value of the policies. Increases in the cash-surrender value are recorded as noninterest income.
Advertising	'
	Advertising – Advertising costs are charged to expense during the year in which they are incurred. Advertising expenses were $894, $779, and $720, for the years ended December 31, 2013, 2012 and 2011, respectively.
Income Taxes	'
	Income Taxes – Income taxes are accounted for using the asset and liability method. Deferred tax assets and liabilities are recognized for the expected future tax consequences attributable to differences between financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are calculated using tax rates in effect for the year in which the differences are expected to reverse. Valuation allowances are established to reduce the net carrying amount of deferred tax assets if it is determined to be more likely than not that all or some of the potential deferred tax asset will not be realized.
	The Company follows the provisions of the Financial Accounting Standards Boards’ (“FASB”) ASC 740, “Income Taxes,” relating to accounting for uncertain tax positions. Uncertain tax positions may arise when the Company takes or expects to take a tax position that is ultimately disallowed by the relevant taxing authority. The Company files income tax returns with the Internal Revenue Service and any states in which it has identified that it has nexus. Tax returns for the years subsequent to 2009 remain open to examination by the taxing jurisdictions. Management reviews the Company’s balance sheet, income statement, income tax provision and income tax returns as well as the permanent and temporary adjustments affecting current and deferred income taxes quarterly and assesses whether uncertain tax positions exist. At December 31, 2013, management does not believe that any uncertain tax positions exist, that are not more-likely-than-not, sustainable upon examination. The Company’s policy with respect to interest and penalties ensuing from income tax settlements is to recognize them as noninterest expense.
Earnings Per Share	'
	Earnings Per Share – Basic earnings per share are computed by dividing net income by the weighted average number of shares outstanding during the period. Diluted earnings per share include the effect of common stock equivalents that would arise from the exercise of stock options discussed in Note 15. Weighted shares outstanding are adjusted retroactively for the effect of stock dividends.
	Weighted average shares outstanding at December 31, are as follows:
			2013		2012		2011
	Basic			17,871,439		18,085,607		18,427,657
	Common stock equivalents attributable to stock-based compensation plans			188,484		152,553		91,890
	Diluted			18,059,923		18,238,160		18,519,547
	Equity grants, including options and Stock Appreciation Rights, for 368,705, 452,480 and 266,859 shares of common stock were excluded from the diluted earnings per share calculation in 2013, 2012 and 2011, respectively, due to their anti-dilutive effect.
Share-Based Payment Plans	'
	Share-Based Payment Plans – Financial accounting standards require companies to measure and recognize compensation expense for all share-based payments at the grant date based on the fair value of the award, as defined in FASB ASC 718, “Stock Compensation,” and include such costs as an expense in their income statements over the requisite service (vesting) period. The Company estimates the impact of forfeitures based on historical experience with previously granted share-based compensation awards, and considers the impact of the forfeitures when determining the amount of expense to record. The Company generally issues new shares of common stock to satisfy stock option exercises. The Company uses the Black-Scholes option pricing model to measure fair value. No options or Stock Appreciation Rights (“SARs”) were granted in 2012 or 2013. ISOs, nonqualified stock options, restricted stock, restricted stock units, and stock-settled SARs are recognized as equity-based awards and compensation expense is recorded to the income statement over the requisite vesting period based on the grant-date fair value. SARs settled in cash are recognized on the balance sheet as liability-based awards. The grant-date fair value of liability-based awards vesting in the current period, along with the change in fair value of the awards during the period, are recognized as compensation expense and as an adjustment to the recorded liability.
Fair Value Measurements	'
	Fair Value Measurements – Generally accepted accounting principles define fair value as 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. FASB ASC 820, “Fair Value Measurements,” establishes a three-level hierarchy for disclosure of assets and liabilities recorded at fair value. The classification of assets and liabilities within the hierarchy is based on whether the inputs to the valuation methodology used for measurement are observable or unobservable. Observable inputs reflect market-derived or market-based information obtained from independent sources while unobservable inputs reflect our estimates about market data. In general, fair values determined by Level 1 inputs utilize quoted prices for identical assets or liabilities traded in active markets that the Company has the ability to access. Fair values determined by Level 2 inputs utilize inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. Level 2 inputs include quoted prices for similar assets and liabilities in active markets and inputs other than quoted prices that are observable for the asset or liability, such as interest rates and yield curves that are observable at commonly quoted intervals. Level 3 inputs are unobservable inputs for the asset or liability and include situations where there is little, if any, market activity for the asset or liability. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, the level in the fair value hierarchy within which the fair value measurement in its entirety falls has been determined based on the lowest level input that is significant to the fair value measurement in its entirety. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the asset or liability.
Recently Issued Accounting Pronouncements	'
	Recently Issued Accounting Pronouncements –
	In July 2012, the FASB issued ASU No. 2012-02, Testing Indefinite-Lived Intangible Assets for Impairment. With this update, a company testing indefinite-lived intangibles for impairment now has the option to assess qualitative factors to determine whether the existence of events and circumstances indicates that it is more likely than not that the indefinite-lived intangible asset is impaired. If, after assessing the totality of events and circumstances, an entity concludes that it is not more likely than not that the indefinite-lived intangible asset is impaired, then the entity is not required to take further action. However, if an entity concludes otherwise, then it is required to determine the fair value of the indefinite-lived intangible asset and perform the quantitative impairment test by comparing the fair value with the carrying amount in accordance with current guidance. An entity also has the option to bypass the qualitative assessment for any indefinite-lived intangible asset in any period and proceed directly to performing the quantitative impairment test. An entity will be able to resume performing the qualitative assessment in any subsequent period. The amendments are effective for annual and interim goodwill impairment tests performed for fiscal years beginning after September 15, 2012. The adoption of this ASU is not expected to have a material impact on the Company’s consolidated financial statements.
	In February 2013, the FASB issued ASU No. 2013-02, Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income. The Update requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component and to present either on the face of the statement where net income is presented, or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income, but only if the amount reclassified is required to be reclassified to net income in its entirety in the same reporting period. The amendments are effective for annual and interim reporting periods beginning on or after December 15, 2013. The Company is currently in the process of evaluating the ASU but does not expect it will have a material impact on the Company’s consolidated financial statements.
	In July 2013, the FASB issued ASU No. 2013-10, Inclusion of the Fed Funds Effective Swap Rate (or Overnight Index Swap Rate) as a Benchmark Interest Rate for Hedge Accounting Purposes . ASU No. 2013-10 permits the use of the Fed Funds Effective Swap Rate (OIS) to be used as a U.S. benchmark interest rate for hedge account purposes. The amendment is effective prospectively for qualifying new or redesiginated hedging relationships entered into on or after July 17, 2013. The adoption of ASU No. 2013-10 did not have a material impact on the Company’s consolidated financial statements.
	In July 2013, the FASB issued ASU No. 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists. ASU No. 2013-11 requires an entity to present an unrecognized tax benefit, or a portion of an unrecognized tax benefit, as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward, except to the extent a net operating loss carryforward, a similar tax loss, or a tax credit carryforward is not available at the reporting date under the tax law of the applicable jurisdiction to settle any additional income taxes that would result from the disallowance of a tax position or the tax law of the applicable jurisdiction does not require the entity to use, and the entity does not intend to use, the deferred tax asset for such purpose, the unrecognized tax benefit should be presented in the financial statements as a liability and should not be combined with deferred tax assets. No new recurring disclosures are required. The amendments are effective for annual and interim reporting periods beginning on or after December 15, 2013 and are to be applied prospectively to all unrecognized tax benefits that exist at the effective date. Retrospective application is permitted. The adoption of ASU No. 2013-11 is not expected to have a material impact on the Company’s consolidated financial statements.
	In January 2014, the FASB issued ASU No. 2014-01, Accounting for Investments in Qualified Affordable Housing Projects. ASU 2014-04 permit an entity to make an accounting policy election to account for their investments in qualified affordable housing projects using the proportional amortization method if certain conditions are met. Under the proportional amortization method, an entity amortizes the initial cost of the investment in proportion to the tax credits and other tax benefits received and recognize the net investment performance in the income statement as a component of income tax expense (benefit). The amendments are effective for annual and interim reporting periods beginning on or after December 15, 2014 and should be applied prospectively. The Company is currently reviewing the requirements of ASU No. 2014-01, but does not expect the ASU to have a material impact on the Company’s consolidated financial statements.
	In January 2014, the FASB issued ASU No. 2014-04, Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon foreclosure. ASU 2014-04 clarifies that an in substance repossession or foreclosure occurs, and a creditor is considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan, upon either (1) the creditor obtaining legal title to the residential real estate property upon completion of a foreclosure or (2) the borrower conveying all interest in the residential real estate property to the creditor to satisfy that loan through completion of a deed in lieu of foreclosure or through a similar legal agreement. Additionally, the amendments require interim and annual disclosure of both (1) the amount of foreclosed residential real estate property held by the creditor and (2) the recorded investment in consumer mortgage loans collateralized by residential real estate property that are in the process of foreclosure according to local requirements of the applicable jurisdiction. The amendments are effective for annual and interim reporting periods beginning on or after December 15, 2014 and can be applied with a modified retrospective transition method or prospectively. The adoption of ASU No. 2014-04 is not expected to have a material impact on the Company’s consolidated financial statements.
