Accounting Policies [Abstract]
Summary of Significant Accounting Policies	NOTE 1 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: Principles of 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 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”) . Use of Estimates Cash and Cash Equivalents Securities Available-for-Sale 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. The cost basis of an other-than-temporarily impaired security is written down by the amount of impairment recognized in earnings. The new cost basis is not adjusted for subsequent recoveries in fair value. However, the difference between the new amortized cost basis and the cash flows expected to be collected is accreted as interest income. 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, Income Recognition, and the Allowance for Loan Losses 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. Purchased Credit Impaired Loans (“PCI Loans”) Loans acquired with evidence of credit deterioration since origination for which it is probable that all contractually required payments will not be collected are accounted for under ASC 310-30, Loans and Debt Securities Acquired with Deteriorated Credit Quality, Accounting for Certain Loans or Debt Securities Acquired in a Transfer. 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. During the second quarter 2013, 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. 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. 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 where 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 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 – Accrued Interest and Other Payables Foreclosed Assets 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 FHLB stock is generally viewed as a 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 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 – Bank-owned Life Insurance Advertising Income Taxes 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, 2015, 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.

The acquisition of Capital Pacific Bank reflects the Company’s overall banking expansion strategy, and expanded the combined Bank’s presence in the Portland market. The transaction has been accounted for under the acquisition method of accounting. The assets and liabilities were recorded at their estimated fair values as of the acquisition dates. The application of the acquisition method resulted in the recognition of goodwill of $16,374, which is all attributable to the value of Capital Pacific’s lending and deposit gathering banking activities. None of the goodwill is deductible for income tax purposes as the Merger is accounted for as a tax-free exchange. Below is a reconciliation of the goodwill associated with the transaction: March 6, 2015 Cost basis net assets $ 26,847 Less: Cash payment to shareholders (16,413 ) Cash payment to employees and directors (1,609 ) Stock issued (23,578 ) Fair value adjustments: Loans and leases, net (5,376 ) Core deposit intangible 3,721 Other 34 Goodwill $ (16,374 ) Pursuant to the terms of the merger agreement, former Capital Pacific Bancorp shareholders received either $16.00 per share in cash or 1.132 shares of Pacific Continental common stock for each share of Capital Pacific Bancorp common stock, or a combination of 40.0% in the form of cash and 60.0% in the form of Pacific Continental common stock. Pursuant to the merger agreement, the maximum aggregate cash component of the merger consideration was $16,413 and the aggregate stock component of the merger consideration was 1,778,102 shares of Pacific Continental common stock, the value of which was calculated based on a closing stock price of $13.21per share. The cash election was oversubscribed; therefore shareholders electing all cash received $7.55 in cash and 0.598 shares of Pacific Continental common stock for each share of Capital Pacific common stock. Former Capital Pacific shareholders making a valid mixed election received $6.40 in cash and 0.679 shares of Pacific Continental common stock for each share of Capital Pacific common stock. The operations of Capital Pacific Bank are included in the operating results beginning March 6, 2015. Capital Pacific Bank’s results of operations prior to the acquisition are not included in the operating results. Revenue information for Capital Pacific Bank related revenue and expense cannot be practically separated from Pacific Continental, therefore proforma revenue disclosures have not been included. Merger-related expense of $1,836 was incurred during the first quarter 2015 in connection with the acquisition of Capital Pacific Bank and recognized within the merger-related expense line item on the Consolidated Statements of Income. Accrued restructuring charges relating to the Capital Pacific Bank acquisition were recorded in other liabilities and had a remaining balance of $12 at December 31, 2015. Included in Capital Pacific Bancorp’s outstanding liabilities at March 6, 2015, was a note payable to Bell State Bank, in the amount of $3,344, including accrued interest. This figure represents debt Capital Pacific Bancorp incurred in connection with the payoff of their TARP funds. This debt was satisfied at merger closing by Pacific Continental Bank. The statement of assets acquired and liabilities assumed at their fair values are presented below as of the transaction closing date: CAPITAL PACIFIC BANCORP Opening balance sheet (in thousands) March 6, 2015 ASSETS Securities available-for-sale $ 26,010 Gross loans 208,782 Fair value adjustments Credit quality-related (3,316 ) Interest rate-related (2,060 ) Net loans 203,406 Interest receivable 547 Federal Home Loan Bank stock 627 Property and equipment 229 Goodwill 16,374 Core deposit intangible 3,721 Deferred tax asset 1,226 Taxes receivable 656 Other real estate owned 845 Bank-owned life insurance 5,683 Other asset 201 Total assets $ 259,525 LIABILITIES AND SHAREHOLDERS EQUITY Deposits $ 227,967 Other liabilities 4,731 Total liabilities 232,698 Common stock 23,578 Cash paid, net of cash acquired 3,249 Total liabilities and shareholders’ equity $ 259,525 The acquisition of Capital Pacific Bank is not considered significant to the Company’s consolidated financial statements and therefore pro forma financial information is not presented.

Securities Available-for-Sale	NOTE 4—SECURITIES AVAILABLE-FOR-SALE: The amortized cost and estimated fair values of securities available-for-sale at December 31, 2015, are as follows: Gross Gross Estimated Percentage Amortized Unrealized Unrealized Fair of Cost Gains Losses Value Portfolio Unrealized Loss Positions Obligations of U.S. government agencies $ 14,491 $ — $ (119 ) $ 14,372 3.92 % Obligations of states and political subdivisions 13,438 — (149 ) 13,289 3.62 % Private-label mortgage-backed securities 663 — (33 ) 630 0.17 % Mortgage-backed securities 95,040 — (856 ) 94,184 25.69 % SBA pools 17,225 — (101 ) 17,124 4.67 % Corporate securities 899 — (5 ) 893 0.25 % $ 141,756 $ — $ (1,263 ) $ 140,492 38.32 % Unrealized Gain Positions Obligations of U.S. government agencies $ 29,669 $ 582 $ — $ 30,251 8.25 % Obligations of states and political subdivisions 80,119 3,743 — 83,862 22.88 % Private-label mortgage-backed securities 2,028 131 — 2,159 0.59 % Mortgage-backed securities 90,126 1,060 — 91,186 24.87 % SBA pools 18,560 88 — 18,648 5.09 % Corporate securities — — — — 0.00 % $ 220,502 $ 5,604 $ — $ 226,106 61.68 % $ 362,258 $ 5,604 $ (1,263 ) $ 366,598 100.00 % At December 31, 2015, unrealized losses exist on certain securities classified as obligations of U.S. government agencies, obligations of states and political subdivisions, mortgage-backed securities, private-label mortgage-backed securities and SBA pools. The unrealized losses on all securities are deemed to be temporary, as these securities retain strong credit ratings, continue to perform adequately, and are backed by various government sponsored enterprises. 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 to changes in interest rates relative to where these investments fall within the yield curve and their individual characteristics. Because the Company does not currently intend to sell these securities nor does the Company consider it more likely than not that it will be required to sell these securities before the recovery of amortized cost basis, which may be upon maturity, the Company does not consider these investments to be other-than-temporarily impaired at December 31, 2015. The following table presents a summary of securities in a continuous unrealized loss position as December 31, 2015: Securities in Gross Unrealized Securities in Gross Unrealized Continuous Loss on Continuous Loss on Unrealized Securities in Unrealized Securities in Loss Positions Loss Position Loss Positions Loss Position for less than 12 for Less than for 12 Months for 12 Months Months 12 Months or Longer or Longer Obligations of U.S. government agencies $ 14,372 $ (119 ) $ — $ — Obligations of states and political subdivisions 12,761 (145 ) 528 (4 ) Private-label mortgage-backed securities 240 (4 ) 390 (29 ) Mortgage-backed securities 87,896 (711 ) 6,288 (145 ) SBA variable rate pools 13,539 (78 ) 3,585 (23 ) Corporate securities 893 (5 ) — — $ 129,701 $ (1,062 ) $ 10,791 $ (201 ) On a monthly basis management reviewed all of its private-label mortgage-backed securities for the presence of OTTI and during 2015 recorded $22 on one security. 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. 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 2015, 2014 and 2013: December 31, 2015 2014 2013 Balance, beginning of period: $ 227 $ 227 $ 204 Additions: OTTI credit loss recorded 22 — 23 Less: OTTI reduction from sale or maturity — — — Balance, end of period: $ 249 $ 227 $ 227 At December 31, 2015, six of the Company’s private-label mortgage-backed securities with an amortized cost of $1,506 were classified as substandard as their ratings were below investment grade. Securities with an amortized cost of $1,879 and $2,593 were classified as substandard at December 31, 2014, and December 31, 2013, respectively. At December 31, 2015 the projected average life of the securities portfolio was 4.21 years and its modified duration was 3.73 years.

Loans, Allowance for Loan Losses, and Credit Quality Indicators	NOTE 5 – 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 at December 31 are as follows: December 31, % of gross December 31, % of gross 2015 loans 2014 loans Real estate secured loans: Multi-family residential $ 66,445 4.7 % $ 51,586 4.9 % Residential 1-4 family 53,776 3.8 % 47,222 4.5 % Owner-occupied commercial 364,742 26.0 % 259,805 24.8 % Nonowner-occupied commercial 300,774 21.4 % 201,558 19.3 % Total permanent real estate loans 785,737 55.9 % 560,171 53.5 % Construction loans: Multi-family residential 7,027 0.5 % 8,472 0.8 % Residential 1-4 family 30,856 2.2 % 28,109 2.7 % Commercial real estate 42,680 3.0 % 18,595 1.8 % Commercial bare land and acquisition & development 20,537 1.5 % 12,159 1.2 % Residential bare land and acquisition & development 7,268 0.5 % 6,632 0.6 % Total construction real estate loans 108,368 7.7 % 73,967 7.1 % Total real estate loans 894,105 63.6 % 634,138 60.6 % Commercial loans 501,976 35.7 % 406,568 38.9 % Consumer loans 3,351 0.2 % 3,862 0.4 % Other loans 6,580 0.5 % 1,443 0.1 % Gross loans 1,406,012 100.00 % 1,046,011 100.0 % Deferred loan origination fees (1,530 ) (990 ) 1,404,482 1,045,021 Allowance for loan losses (17,301 ) (15,637 ) Total loans, net of allowance for loan losses and net deferred fees $ 1,387,181 $ 1,029,384 At December 31, 2015, outstanding loans to dental professionals totaled $340,162 and represented 24.19% of total outstanding loans compared to dental professional loans of $306,391 or 29.29% of total loans at December 31, 2014. Additional information about the Company’s dental portfolio can be found in Note 6. There are no other industry concentrations in excess of 10.00% of the total loan portfolio. However, as of December 31, 2015, 63.60% 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. Purchased Loans The following table represents the contractually required principal payments and the carrying balance of loans acquired in the Century Bank acquisition and the Capital Pacific Bank acquisition, at December 31, 2015, 2014 and 2013, respectively. December 31, 2015 2014 2013 Contractually required principal payments $ 183,347 $ 28,187 $ 44,358 Purchase adjustment for credit and interest rate (3,958 ) (881 ) (1,341 ) Balance of acquired loans $ 179,389 $ 27,306 $ 43,017 Purchased Credit Impaired Loans On March 6, 2015, the Bank acquired purchased credit impaired loans with a fair value of $9,464, associated with the Capital Pacific Acquisition. The contractually required principal and interest payments at acquisition totaled $13,897, of which $646 were not expected to be collected . The following table represents the contractually required principal balance of purchased impaired loans and the carrying balance at December 31, 2015, 2014 and 2013: December 31, 2015 2014 2013 Contractually required principal payments for purchased credit impaired loans $ 11,528 $ 2,753 $ 3,257 Accretable yield (1,070 ) (151 ) (377 ) Nonaccretable yield (378 ) (321 ) (321 ) Balance of purchased credit impaired loans $ 10,080 $ 2,282 $ 2,559 The following tables summarize the changes in the accretable yield for purchased impaired loans for the year ended December 31, 2015 and 2014: Year ended December 31, 2015 Century Capital Pacific Total Balance, beginning of period $ 151 $ — $ 151 Additions — 1,569 1,569 Accretion to interest income (111 ) (539 ) (650 ) Balance, end of period $ 40 $ 1,030 $ 1,070 Year ended Century Balance, beginning of period $ 377 Additions — Accretion to interest income (226 ) Balance, end of period $ 151 Allowance for Loan Losses 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 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, and • 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, and • Peer comparison loss rates. During 2013, 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 following tables present a summary of the activity in the allowance for loan losses by major loan classification for the periods ended December 31, 2015, 2014 and 2013: For the year ended December 31, 2015 Commercial Real Construction Consumer Unallocated Total Beginning balance $ 5,733 $ 7,494 $ 1,077 $ 54 $ 1,279 $ 15,637 Charge-offs (630 ) (61 ) — (9 ) — (700 ) Recoveries 562 76 16 15 — 669 Provision (reclassification) 684 788 165 (14 ) 72 1,695 Ending balance $ 6,349 $ 8,297 $ 1,258 $ 46 $ 1,351 $ 17,301 For the year ended December 31, 2014 Commercial Real Construction Consumer Unallocated Total Beginning balance $ 5,113 $ 7,668 $ 1,493 $ 68 $ 1,575 $ 15,917 Charge-offs (610 ) (58 ) (155 ) (12 ) — (835 ) Recoveries 348 186 16 5 — 555 Provision (reclassification) 882 (302 ) (277 ) (7 ) (296 ) — Ending balance $ 5,733 $ 7,494 $ 1,077 $ 54 $ 1,279 $ 15,637 For the year ended December 31, 2013 Commercial Real Construction Consumer Unallocated Total Beginning balance $ 3,846 $ 9,456 $ 1,987 $ 70 $ 986 $ 16,345 Charge-offs (1,658 ) (407 ) — (23 ) — (2,088 ) Recoveries 982 360 60 8 — 1,410 Provision (reclassification) 1,943 (1,741 ) (554 ) 13 589 250 Ending balance $ 5,113 $ 7,668 $ 1,493 $ 68 $ 1,575 $ 15,917 The following table presents the allowance and recorded investment in loans by major loan classification at December 31, 2015, and 2014: December 31, 2015 Commercial Real Construction Consumer Unallocated Total Ending allowance: collectively evaluated for impairment $ 6,303 $ 8,267 $ 1,159 $ 46 $ 1,351 $ 17,126 Ending allowance: individually evaluated for impairment 46 30 99 — — 175 Ending allowance: loans acquired with deteriorated credit quality — — — — — — Total ending allowance $ 6,349 $ 8,297 $ 1,258 $ 46 $ 1,351 $ 17,301 Ending loan balance: collectively evaluated for impairment $ 504,261 $ 771,543 $ 107,977 $ 3,351 $ — $ 1,387,132 Ending loan balance: individually evaluated for impairment 2,627 5,782 391 — — 8,800 Ending loan balance: loans acquired with deteriorated credit quality 1,668 8,412 — — — 10,080 Total ending loan balance $ 508,556 $ 785,737 $ 108,368 $ 3,351 $ — $ 1,406,012 December 31, 2014 Commercial Real Construction Consumer Unallocated Total Ending allowance: collectively evaluated for impairment $ 5,662 $ 7,438 $ 959 $ 54 $ 1,279 $ 15,392 Ending allowance: individually evaluated for impairment 71 56 118 — — 245 Ending allowance: loans acquired with deteriorated credit quality — — — — — — Total ending allowance $ 5,733 $ 7,494 $ 1,077 $ 54 $ 1,279 $ 15,637 Ending loan balance: collectively evaluated for impairment $ 405,414 $ 553,655 $ 73,610 $ 3,862 $ — $ 1,036,541 Ending loan balance: individually evaluated for impairment 2,514 4,317 357 — — 7,188 Ending loan balance: loans acquired with deteriorated credit quality 83 2,199 — — — 2,282 Total ending loan balance $ 408,011 $ 560,171 $ 73,967 $ 3,862 $ — $ 1,046,011 The 2015 ending allowance includes $175 in specific allowance for $8,800 of impaired loans ($7,527 net of government guarantees). At December 31, 2014, the Company had $7,188 of impaired loans ($6,065 net of government guarantees) with a specific allowance of $245 assigned. Management believes that the allowance for loan losses was adequate as of December 31, 2015. 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 – Special Mention Substandard – Doubtful – 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.

Potentially impaired loans are referred to the ALCO 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 following tables display an analysis of the Company’s impaired loans at December 31, 2015, and 2014: Impaired Loan Analysis As of December 31, 2015 Recorded Specific Recorded With Specific Recorded Unpaid Average Related Real estate Multi-family residential $ — $ — $ — $ — $ — $ — Residential 1-4 family 374 308 682 911 766 5 Owner-occupied commercial 2,788 — 2,788 2,788 1,177 — Nonowner-occupied commercial 2,287 25 2,312 2,374 2,395 25 Total real estate loans 5,449 333 5,782 6,073 4,338 30 Construction Multi-family residential — — — — — — Residential 1-4 family 53 — 53 72 32 — Commercial real estate — — — — — — Commercial bare land and acquisition & development — — — — — — Residential bare land and acquisition & development — 338 338 338 347 99 Total construction loans 53 338 391 410 379 99 Commercial and other 2,091 536 2,627 3,018 2,404 46 Consumer — — — — — — Total impaired loans $ 7,593 $ 1,207 $ 8,800 $ 9,501 $ 7,121 $ 175 Impaired Loan Analysis As of December 31, 2014 Recorded Specific Recorded Specific Recorded Unpaid Average Related Real estate Multi-family residential $ — $ — $ — $ — $ — $ — Residential 1-4 family 455 313 768 996 1,005 2 Owner-occupied commercial 1,046 — 1,046 1,046 1,756 — Nonowner-occupied commercial 2,449 54 2,503 2,523 1,927 54 Total real estate loans 3,950 367 4,317 4,565 4,688 56 Construction Multi-family residential — — — — — — Residential 1-4 family — — — — — — Commercial real estate — — — — — — Commercial bare land and acquisition & development — — — — — — Residential bare land and acquisition & development — 357 357 357 365 118 Total construction loans — 357 357 357 365 118 Commercial and other 1,942 572 2,514 2,823 3,831 71 Consumer — — — — — — Total impaired loans $ 5,892 $ 1,296 $ 7,188 $ 7,745 $ 8,884 $ 245 The impaired balances reported above are not adjusted for government guarantees of $1,273 and $1,123 at December 31, 2015, and December 31, 2014, respectively. The recorded investment in impaired loans, net of government guarantees, totaled $7,527 and $6,065 at December 31, 2015, and December 31, 2014, 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 following table displays the Company’s TDRs by class at December 31, 2015, and 2014: Troubled Debt Restructurings as of December 31, 2015 December 31, 2014 Number of Outstanding Recorded Number of Outstanding Recorded Real estate Multifamily residential — $ — — $ — Residential 1-4 family 6 682 7 768 Owner-occupied commercial 3 2,788 2 1,046 Non owner-occupied commercial 7 2,312 7 2,503 Total real estate loans 16 5,782 16 4,317 Construction Multifamily residential — — — — Residential 1-4 family — — — — Commercial real estate — — — — Commercial bare land and acquisition & development — — — — Residential bare land and acquisition & development — — — — Total construction loans — — — — Commercial and other 11 2,170 12 2,259 Consumer — — — — 27 $ 7,952 28 $ 6,576 The recorded investment on TDRs in nonaccrual status totaled $1,807 and $1,649 at December 31, 2015, and December 31, 2014, 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, 2015, the Company restructured two loans into troubled debt testructurings for which impairment was previously measured under the Company’s general loan loss allowance methodology. The total recorded investment in such receivables was $2,077, and the associated allowance for loan losses was $0 at December 31, 2015. The types of modifications offered can generally be described in the following categories: Rate Modification Term Modification Interest Only Modification Combination Modification The following tables present newly restructured loans that occurred during the twelve months ended December 31, 2015, and 2014, respectively: Troubled Debt Restructurings Identified during the twelve months ended December 31, 2015 Rate Term Interest Only Combination Real estate Multifamily residential $ — $ — $ — $ — Residential 1-4 family — — — — Owner-occupied commercial — 1,780 — — Non owner-occupied commercial — — — — Total real estate loans — 1,780 — — Construction Multifamily residential — — — — Residential 1-4 family — — — — Commercial real estate — — — — Commercial bare land and acquisition & development — — — — Residential bare land and acquisition & development — — — — Total construction loans — — — — Commercial and other 297 — — — Consumer — — — — $ 297 $ 1,780 $ — $ — Troubled Debt Restructurings Identified during the twelve months ended December 31, 2014 Rate Term Interest Only Combination Real estate Multifamily residential $ — $ — $ — $ — Residential 1-4 family — — — — Owner-occupied commercial — — — — Non owner-occupied commercial — 1,597 548 — Total real estate loans — 1,597 548 — Construction Multifamily residential — — — — Residential 1-4 family — — — — Commercial real estate — — — — Commercial bare land and acquisition & development — — — — Residential bare land and acquisition & development — — — — Total construction loans — — — — Commercial and other 221 274 483 — Consumer — — — — $ 221 $ 1,871 $ 1,031 $ — Subsequent to a loan being classified as a TDR, a borrower may become unwilling or unable to abide by the terms of the modified agreement.

Loan Participations and Servicing	NOTE 7 – 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 in the aggregate is 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 13 – 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 14 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, 2015, 2014, and 2013, the Company recognized net interest expense of $226, $225, and $200, respectively, related to the Trust Preferred Securities.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments	NOTE 14 – DERIVATIVE INSTRUMENTS: 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, 2015, was an $82 unrealized gain, which is recorded in the other asset section of the balance sheet, net of the tax effect. 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 deposited cash collateral totaling $401 with a counterparty as of April 22, 2013, to satisfy collateral requirements associated with the interest rate swap contract. Upon the acquisition of Capital Pacific Bank on March 6, 2015, the Bank acquired three interest rate swaps entered into by Capital Pacific Bank with commercial banking customers tied to loans on the balance sheet. Those interest rate swaps are simultaneously hedged by offsetting the interest rate swaps that the Bank executes with a third party, such that the Bank minimizes its net risk exposure. As of December 31, 2015, the Bank had interest rate swaps with an aggregate notional amount of approximately $8,774, related to this program. The Bank does not require separately pledged collateral to secure its interest rate swaps with customers. However, it does make a practice of cross-collateralizing the interest rate swaps with collateral on the underlying loan. The termination value of derivatives in a net liability position, which includes accrued interest but excludes any adjustment for nonperformance risk, related to these agreements was approximately $23 as of December 31, 2015. The Bank has minimum collateral posting thresholds with certain of its derivative counterparties, and has posted collateral totaling $250 consisting of cash held on deposit for the benefit of the counterparty against its obligations under these agreements as of December 31, 2015. The Bank has also entered into a swap with a third party to serve as a hedge to an equal amount of fixed rate loans. As of December 31, 2015, the Bank had one swap designated a hedging instrument with a notional amount of $1,525 hedging a 10-year fixed rate note bearing interest at 5.71% and maturing August 2023. The notional amount does not represent direct credit exposure. Direct credit exposure is limited to the net difference between the calculated amount to be received and paid. As the Bank has designated the swap a fair value hedge, the underlying hedged loan is carried at fair value on the consolidated balance sheet and included in loans, net of allowance for loan losses and unearned fees. The following tables present quantitative information pertaining to the interest rate swaps as of December 31, 2015: December 31, 2015 Hedge - Not-Hedge - Designated Designated Notional amount $ 1,525 $ 8,774 Weighted average pay rate 5.71 % 4.85 % Weighted average receive rate 3.20 % 3.28 % Weighted average maturity in years 7.60 6.49 The following table presents the fair values of interest rate swaps and their locations in the Consolidate Balance Sheets as of December 31, 2015 and 2014: Asset Derivatives Liability Derivatives Balance sheet December 31, December 31, Derivative location 2015 2014 2015 2014 Interest rate swap designated as a hedging instrument Other assets or $ 66 $ — $ 93 $ — Interest rate swaps not designated as hedging instruments Other assets or $ 24 $ — $ 24 $ — The following table presents the income statement impact of these interest rate swaps for the years ended December 31, 2015, 2014 and 2013: Derivative Income statement location 2015 2014 2013 Interest rate swap designated as a hedging instrument Other noninterest $ — $ — $ — Interest rate swaps not designated as a hedging instrument Other noninterest $ 5 $ — $ — $ 5 $ — $ —

Share-Based Compensation	NOTE 17 – 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 Disclosure [Abstract]
Commitments and Contingencies	NOTE 21 – 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, 2015 and 2014 consist of the following: December 31, 2015 2014 Commitments to extend credit (principally variable rate) $ 256,156 $ 156,972 Letters of credit and financial guarantees written $ 1,184 $ 1,564 The Company has entered into Executive Employment Agreements with two key executive officers. The employment agreements provide for minimum aggregate annual base salaries of $812, plus performance adjustments, life insurance coverage, and other perquisites commonly found in such agreements. The two employment agreements expire in 2016 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.

The estimated fair values of the financial instruments at December 31, 2015 and 2014, are as follows: December 31, 2015 2014 Carrying Fair Value Carrying Fair Value Financial assets: Cash and cash equivalents $ 36,675 $ 36,675 $ 25,787 $ 25,787 Securities available-for-sale 366,598 366,598 351,946 351,946 Loans 1,404,482 1,389,562 1,045,021 1,033,254 Interest receivable 5,721 5,721 4,773 4,773 Federal Home Loan Bank stock 5,208 5,208 10,019 10,019 Bank-owned life insurance 22,884 22,884 16,609 16,609 Interest rate swaps 171 171 176 176 Financial liabilities: Deposits $ 1,597,093 $ 1,597,280 $ 1,209,093 $ 1,209,240 Federal Home Loan Bank borrowings 77,500 77,651 96,000 96,721 Junior subordinated debentures 8,248 2,741 8,248 2,410 Accrued interest payable 138 138 176 176 Interest rate swaps 116 116 — — Cash and Cash Equivalents Securities available-for-sale – Accrued Interest receivable Loans Federal Home Loan Bank stock Bank-owned life insurance Swap Derivative – Deposits Federal Home Loan Bank Borrowings Junior Subordinated Debentures Accrued Interest payable Off-Balance Sheet Financial Instruments 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, 2015, and 2014: Carrying Amount Fair Value at December 31, 2015 Level 1 Level 2 Level 3 Financial assets: Cash and cash equivalents $ 36,675 $ 36,675 $ — $ — Loans 1,404,482 — — 1,389,562 Interest receivable 5,721 5,721 — — Federal Home Loan Bank stock 5,208 5,208 — — Bank-owned life insurance 22,884 22,884 — — Interest rate swaps 171 171 — — Financial liabilities: Deposits $ 1,597,093 $ — $ 1,597,280 $ — Federal Home Loan Bank borrowings 77,500 — 77,651 — Junior subordinated debentures 8,248 — 2,741 — Accrued interest payable 138 138 — — Interest rate swaps 116 116 — — Carrying Amount Fair Value at December 31, 2014 Level 1 Level 2 Level 3 Financial assets: Cash and cash equivalents $ 25,787 $ 25,787 $ — $ — Loans 1,045,021 — — 1,033,254 Interest receivable 4,773 4,773 — — Federal Home Loan Bank stock 10,019 10,019 — — Bank-owned life insurance 16,609 16,609 — — Swap derivative 176 176 — — Financial liabilities: Deposits $ 1,209,093 $ — $ 1,209,240 $ — Federal Home Loan Bank borrowings 96,000 — 96,721 — Junior subordinated debentures 8,248 — 2,410 — Accrued interest payable 176 176 — — The tables below show assets/liabilities measured at fair value on a recurring basis as of December 31, 2015, and December 31, 2014: Carrying Fair Value Measurements Using December 31, 2015 Quoted (Level1) Significant (Level 2) Significant (Level 3) Available-for-sale securities Obligations of U.S government agencies $ 44,623 $ — $ 44,623 $ — Obligation of states and political subdivisions 97,151 — 97,151 — Agency mortgage-backed securities 185,370 — 185,370 — Private-label mortgage-backed securities 2,790 — 1,204 1,586 SBA variable vate pools 35,771 — 35,771 — Corporate Securities 893 — 893 — Interest rate swaps 55 55 — — Total assets measured on a recurring basis $ 366,653 $ 55 $ 365,012 $ 1,586 Carrying Fair Value Measurements Using December 31, 2014 Quoted (Level1) Significant Significant (Level 3) Available-for-sale securities Obligations of U.S government agencies $ 39,185 $ — $ 39,185 $ — Obligation of states and political subdivisions 83,981 — 83,981 — Agency mortgage-backed securities 205,390 — 205,390 — Private-label mortgage-backed securities 3,816 — 2,248 1,568 SBA variable vate pools 19,574 — 19,574 — Interest rate swaps 176 176 — — Total assets measured on a recurring basis $ 352,122 $ 176 $ 350,378 $ 1,568 No transfers to or from level 1 and 2 occurred on assets measured at fair value on a recurring basis during the twelve months ended December 31, 2015. 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) for the periods ended December 31, 2015, 2014 and 2013: For the Years Ended December 31, 2015 2014 2013 Beginning balance $ 1,568 $ 1,786 $ 1,682 Transfers into Level 3 300 — 332 Transfers out of Level 3 — — — Total gains or losses Included in earnings — — — Included in other comprehensive income 66 (106 ) 80 Paydowns (348 ) (112 ) (308 ) Purchases, issuances, sales, and settlements Purchases — — — Issuances — — — Sales — — — Settlements — — — Ending balance $ 1,586 $ 1,568 $ 1,786 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 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 • Obligations of states and political subdivisions • Private-label mortgage-backed securities • Mortgage-backed securities • SBA variable pools • Corporate securities 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 • Obligations of states and political subdivisions • Private-label mortgage-backed securities • Mortgage-backed securities • SBA pools • Corporate securities 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 June 30, 2015, 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. The tables below show assets measured at fair value on a nonrecurring basis as of December 31, 2015, and 2014: Fair Value Measurements Using December 31, 2015 Carrying Quoted Significant (Level 2) Significant (Level 3) Loans measured for impairment (net of guarantees and specific reserve) $ 53 $ — $ — $ 53 Other real estate owned 10,147 — — 10,147 $ 10,200 — — $ 10,200 Fair Value Measurements Using December 31, 2014 Carrying Quoted (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Loans measured for impairment (net of guarantees and specific reserve) $ 135 $ — $ — $ 135 Other real estate owned 449 — — 449 $ 584 — — $ 584 During second quarter 2015, there was one security that transferred from level 2 to level 3 as the Bank recorded OTTI on a security. For additional information, see Note 4. 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 23 – 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, Tier 1 capital, and common equity Tier 1 to risk-weighted assets and of tier 1 capital to leverage assets. Management believes that, as of December 31, 2015, the Company and the Bank met all capital adequacy requirements to which they were subject. As of December 31, 2015, 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 Adequacy Purposes To Be Well Amount Ratio Amount Ratio Amount Ratio As of December 31, 2015: Total capital (to risk weighted assets) Bank: $ 200,236 12.52 % $ 127,990 8.00 % $ 159,988 10.00 % Company: $ 201,261 12.58 % NA NA Tier 1 capital (to risk weighted assets) Bank: $ 182,575 11.41 % $ 95,993 6.00 % $ 127,990 8.00 % Company: $ 183,600 11.47 % NA NA Common Equity Tier 1 (to risk weighted assets) Bank: $ 182,575 11.41 % $ 71,995 4.50 % $ 103,992 6.50 % Company: $ 175,600 10.97 % NA NA Tier 1 capital (to leverage assets) Bank: $ 182,575 9.88 % $ 73,938 4.00 % $ 92,422 5.00 % Company: $ 183,600 9.93 % NA NA As of December 31, 2014: Total capital (to risk weighted assets) Bank: $ 176,199 15.48 % $ 91,040 8.00 % $ 113,800 10.00 % Company: $ 179,109 15.73 % NA NA Tier 1 capital (to risk weighted assets) Bank: $ 161,954 14.23 % $ 45,520 4.00 % $ 68,280 6.00 % Company: $ 164,864 14.48 % NA NA Tier 1 capital (to leverage assets) Bank: $ 161,954 11.13 % $ 58,193 4.00 % $ 72,741 5.00 % Company: $ 164,864 11.33 % NA NA On July 2, 2013, the federal banking regulators approved the final proposed rules that revised the regulatory capital rules to conform the U.S. regulatory capital framework for U.S. banking organizations to the Basel Committee’s Base III capital framework (“Basel III”). The phase-in period for the final rules began for the Company on January 1, 2015, with full compliance with the final rules entire requirement to be phased in by January 1, 2019. The final rules, among other things, included a new common equity Tier 1 capital (“CET1”) to risk-weighted assets ratio, including a capital conservation buffer composed of CET1, which will gradually increase from 4.50% on January 1, 2015 to 7.00% on January 1, 2019. The final rules also raised the minimum ratio of Tier 1 capital to risk-weighted assets from 4.00% to 6.00%, as well as require a minimum total capital ratio of 8.00% and 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 which 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.

Accounting Policies [Abstract]
Principles of Consolidation	Principles of 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 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”) .
Use of Estimates	Use of Estimates
Cash and Cash Equivalents	Cash and Cash Equivalents
Securities Available-for-Sale	Securities Available-for-Sale 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. The cost basis of an other-than-temporarily impaired security is written down by the amount of impairment recognized in earnings. The new cost basis is not adjusted for subsequent recoveries in fair value. However, the difference between the new amortized cost basis and the cash flows expected to be collected is accreted as interest income. 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, Income Recognition, and the Allowance for Loan Losses	Loans, Income Recognition, and the Allowance for Loan Losses 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. Purchased Credit Impaired Loans (“PCI Loans”) Loans acquired with evidence of credit deterioration since origination for which it is probable that all contractually required payments will not be collected are accounted for under ASC 310-30, Loans and Debt Securities Acquired with Deteriorated Credit Quality, Accounting for Certain Loans or Debt Securities Acquired in a Transfer. 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. During the second quarter 2013, 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. 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. 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 where 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 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 – Accrued Interest and Other Payables
Foreclosed Assets	Foreclosed Assets 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 FHLB stock is generally viewed as a 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 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.

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, 2015, 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.

Loans	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.
Allowance for Loan Losses	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 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, and • 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, and • Peer comparison loss rates.
