Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	NOTE 1 - BASIS OF PRESENTATION The accompanying interim 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 Services Corporation and PCB Loan Services Corporation (both of which are presently inactive). All significant intercompany accounts and transactions have been eliminated in consolidation. The accompanying consolidated financial statements have been prepared by the Company without audit and in conformity with generally accepted accounting principles in the United States of America for interim financial information. The consolidated financial statements include all adjustments and normal accruals, which the Company considers necessary for a fair presentation of the results of operations for such interim periods. In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities, as of the date of the balance sheets and income and expenses for the periods. Actual results could differ from those estimates. The balance sheet data as of December 31, 2015, was derived from audited consolidated financial statements, but does not include all disclosures contained in the Company’s 2015 Form 10-K. The interim consolidated financial statements should be read in conjunction with the December 31, 2015, consolidated financial statements, including the notes thereto, included in the Company’s 2015 Form 10-K.

Investments, Debt and Equity Securities [Abstract]
Securities Available-for-Sale	NOTE 2 – SECURITIES AVAILABLE-FOR-SALE The amortized cost and estimated fair values of securities available-for-sale at March 31, 2016, were 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 $ — $ — $ — $ — 0.00 % Obligations of states and political subdivisions 1,464 — (15 ) 1,449 0.38 % Private-label mortgage-backed securities 275 — (32 ) 243 0.06 % Mortgage-backed securities 32,440 — (165 ) 32,275 8.42 % SBA pools 17,627 — (85 ) 17,542 4.57 % Corporate securities 899 — (8 ) 891 0.23 % $ 52,705 $ — $ (305 ) $ 52,400 13.67 % Unrealized Gain Positions Obligations of U.S. government agencies $ 34,241 $ 1,358 $ — $ 35,599 9.28 % Obligations of states and political subdivisions 93,615 4,780 — 98,395 25.66 % Private-label mortgage-backed securities 2,198 135 — 2,333 0.61 % Mortgage-backed securities 170,174 2,442 — 172,616 45.02 % SBA pools 21,917 182 — 22,099 5.76 % $ 322,145 $ 8,897 $ — $ 331,042 86.33 % $ 374,850 $ 8,897 $ (305 ) $ 383,442 100.00 % At March 31, 2016, the bank held 440 investment securities, of which 31 were in unrealized loss positions. Unrealized losses existed on certain securities classified as obligations of state and political subdivisions, private-label mortgage-backed securities, mortgage-backed securities, SBA pools and corporate securities. 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 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 March 31, 2016. The following table presents a summary of securities in a continuous unrealized loss position at March 31, 2016: Securities in Gross Securities in Gross Obligations of states and political subdivisions $ 1,449 $ (15 ) $ — $ — Private-label mortgage-backed securities — — 243 (32 ) Mortgage-backed securities 24,808 (86 ) 7,467 (79 ) SBA pools 12,662 (37 ) 4,880 (48 ) Corporate securities 891 (8 ) — — $ 39,810 $ (146 ) $ 12,590 $ (159 ) On a monthly basis, management reviews all private-label mortgage-backed securities for the presence of (“OTTI”) and recorded $17 and $0 during the three months ended March 31, 2016 and 2015, respectively. Management’s evaluation included the use of independently-generated first-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 aggregate amount of credit-related OTTI at the beginning and end of the periods presented along with the amounts recognized in earnings during the three months ended March 31, 2016, and 2015: Three months ended March 31, 2016 2015 Balance, beginning of period: $ 249 $ 227 Additions: Initial OTTI credit loss 17 — Balance, end of period: $ 266 $ 227 At March 31, 2016 and December 31, 2015, six of the Company’s private-label mortgage-backed securities, with an amortized cost of $1,428, and $1,506, respectively, were classified as substandard as their underlying credit was considered impaired. At March 31, 2016, and December 31, 2015, the projected average life of the securities portfolio was 4.08 years and 4.21 years, respectively. The amortized cost and estimated fair values of securities available-for-sale at December 31, 2015, were as follows: Amortized Cost Gross Unrealized Gains Gross Unrealized Losses Estimated Fair Value Percentage of 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 0.24 % $ 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 % $ 220,502 $ 5,604 $ — $ 226,106 61.68 % $ 362,258 $ 5,604 $ (1,263 ) $ 366,598 100.00 % At December 31, 2015, the bank held 432 investment securities, of which 92 were in unrealized loss positions.

Receivables [Abstract]
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 of 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 period-end loans are as follows: March 31, % of Gross December 31, % of Gross 2016 Loans 2015 Loans Real estate loans Multi-family residential $ 66,419 4.64 % $ 66,445 4.73 % Residential 1-4 family 51,356 3.59 % 53,776 3.82 % Owner-occupied commercial 373,002 26.06 % 364,742 25.94 % Nonowner-occupied commercial 320,485 22.39 % 300,774 21.39 % Total permanent real estate loans 811,262 56.68 % 785,737 55.88 % Construction loans Multi-family residential 8,747 0.61 % 7,027 0.50 % Residential 1-4 family 29,261 2.04 % 30,856 2.19 % Commercial real estate 40,635 2.84 % 42,680 3.04 % Commercial bare land and acquisition & development 20,518 1.43 % 20,537 1.46 % Residential bare land and acquisition & development 6,562 0.46 % 7,268 0.52 % Total construction real estate loans 105,723 7.38 % 108,368 7.71 % Total real estate loans 916,985 64.06 % 894,105 63.59 % Commercial loans 505,845 35.35 % 501,976 35.70 % Consumer loans 2,948 0.21 % 3,351 0.24 % Other loans 5,525 0.39 % 6,580 0.47 % Gross loans 1,431,303 100.01 % 1,406,012 100.00 % Deferred loan origination fees (1,569 ) (1,530 ) 1,429,734 1,404,482 Allowance for loan losses (17,596 ) (17,301 ) Total loans, net of allowance for $ 1,412,138 $ 1,387,181 At March 31, 2016, outstanding loans to dental professionals totaled $350,940 and represented 24.52% of total outstanding loans compared to dental professional loans of $340,162 or 24.19% of total loans at December 31, 2015. Additional information about the Company’s dental portfolio can be found in Note 4. There are no other industry concentrations in excess of 10.00% of the total loan portfolio. However, as of March 31, 2016, 64.06% 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 Credit Impaired Loans The following table represents the contractually required principal balance of purchased credit impaired loans and the carrying balance at March 31, 2016 and December 31, 2015: March 31, December 31, 2016 2015 Contractually required principal payments for purchase credit impaired loans $ 11,076 $ 11,528 Accretable yield (950 ) (1,070 ) Nonaccretable yield (378 ) (378 ) Balance of purchased credit impaired loans $ 9,748 $ 10,080 The following tables summarize the changes in the accretable yield for purchased credit impaired loans for the periods ended March 31, 2016 and 2015: Three months ended March 31, 2016 Century Capital Total Balance, beginning of period $ 40 $ 1,030 $ 1,070 Additions — — — Accretion to interest income (29 ) (91 ) (120 ) Balance, end of period $ 11 $ 939 $ 950 Three months ended March 31, 2015 Century Capital Total Balance, beginning of period $ 151 $ — $ 151 Additions — 1,569 1,569 Accretion to interest income (29 ) (79 ) (108 ) Balance, end of period $ 122 $ 1,490 $ 1,612 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. A summary of the activity in the allowance for loan losses by major loan classification follows: For the three months ended March 31, 2016 Commercial Real Estate Construction Consumer Unallocated Total Beginning balance $ 6,349 $ 8,297 $ 1,258 $ 46 $ 1,351 $ 17,301 Charge-offs — — — — — — Recoveries 32 9 8 1 — 50 Provision (reclassification) (287 ) 447 (147 ) (4 ) 236 245 Ending balance $ 6,094 $ 8,753 $ 1,119 $ 43 $ 1,587 $ 17,596 For the three months ended March 31, 2015 Commercial Real Estate Construction Consumer Unallocated Total Beginning balance $ 5,733 $ 7,494 $ 1,077 $ 54 $ 1,279 $ 15,637 Charge-offs (32 ) (41 ) — — — (73 ) Recoveries 104 45 5 6 — 160 Provision (reclassification) (255 ) 39 (20 ) (8 ) 244 — Ending balance $ 5,550 $ 7,537 $ 1,062 $ 52 $ 1,523 $ 15,724 At March 31, 2016, the allowance for loan losses on dental loans was $3,884, compared to $4,187 at December 31, 2015, See Note 4 for additional information on the dental loan portfolio.

At December 31, 2015, the Company had $8,800 of impaired loans ($7,527 net of government guarantees) with a specific allowance of $175 assigned. Management believes that the allowance for loan losses was adequate as of March 31, 2016. 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. The following tables present the Company’s loan portfolio information by loan type and credit grade at March 31, 2016 and December 31, 2015: Credit Quality Indicators As of March 31, 2016 Loan Grade Pass Special Mention Substandard Doubtful Totals Real estate loans Multi-family residential $ 66,184 $ — $ 235 $ — $ 66,419 Residential 1-4 family 46,881 — 4,475 — 51,356 Owner-occupied commercial 363,310 — 9,692 — 373,002 Nonowner-occupied commercial 316,356 — 4,129 — 320,485 Total real estate loans 792,731 — 18,531 — 811,262 Construction Multi-family residential 8,747 — — — 8,747 Residential 1-4 family 29,208 — 53 — 29,261 Commercial real estate 40,535 — 100 — 40,635 Commercial bare land and acquisition & development 20,490 — 28 — 20,518 Residential bare land and acquisition & development 4,274 — 2,288 — 6,562 Total construction loans 103,254 — 2,469 — 105,723 Commercial and other 498,057 — 13,313 — 511,370 Consumer 2,947 — 1 — 2,948 Totals $ 1,396,989 $ — $ 34,314 $ — $ 1,431,303 Percentage of portfolio 97.60 % 0.00 % 2.40 % 0.00 % 100.00 % Credit Quality Indicators As of December 31, 2015 Loan Grade Pass Special Mention Substandard Doubtful Totals Real estate loans Multi-family residential $ 66,208 $ — $ 237 $ — $ 66,445 Residential 1-4 family 49,077 — 4,699 — 53,776 Owner-occupied commercial 353,249 — 11,493 — 364,742 Nonowner-occupied commercial 296,528 — 4,246 — 300,774 Total real estate loans 765,062 — 20,675 — 785,737 Construction Multi-family residential 7,027 — — — 7,027 Residential 1-4 family 30,803 — 53 — 30,856 Commercial real estate 42,580 — 100 — 42,680 Commercial bare land and acquisition & development 20,265 — 272 — 20,537 Residential bare land and acquisition & development 4,969 — 2,299 — 7,268 Total construction loans 105,644 — 2,724 — 108,368 Commercial and other 494,267 — 14,289 — 508,556 Consumer 3,350 — 1 — 3,351 Totals $ 1,368,323 $ — $ 37,689 $ — $ 1,406,012 Percentage of portfolio 97.32 % 0.00 % 2.68 % 0.00 % 100.00 % At March 31, 2016 and December 31, 2015, the Company had $437, and $360, respectively, in unfunded commitments on its classified loans, which is included in the calculation of our classified asset ratio. 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.

Potentially impaired loans are referred to the Asset-Liability Committee (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 recorded investment in impaired loans, net of government guarantees, totaled $6,765, and $7,527 at March 31, 2016, and December 31, 2015, 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 March 31, 2016 and December 31, 2015: Troubled Debt Restructurings as of March 31, 2016 December 31, 2015 Number of Post-Modification Number of Post-Modification Real estate Multifamily residential — $ — — $ — Residential 1-4 family 6 669 6 682 Owner-occupied commercial 2 998 3 2,788 Non owner-occupied commercial 7 2,279 7 2,312 Total real estate loans 15 3,946 16 5,782 Construction Multifamily residential — — — — Residential 1-4 family — — — — Commercial real estate — — — — Commercial bare land and acquisition & development — — — — Residential bare land and acquisition & development 2 1,838 — — Total construction loans 2 1,838 — — Commercial and other 16 3,229 11 2,170 Consumer — — — — Total 33 $ 9,013 27 $ 7,952 The recorded investment in TDRs on nonaccrual status totaled $2,320, and $1,807 at March 31, 2016 and December 31, 2015, respectively. The Company’s policy is that loans placed on nonaccrual will typically remain on nonaccrual status until all principal and interest payments are brought current and the prospect for future payment in accordance with the loan agreement appears relatively certain. The Company’s policy generally refers to a minimum of six months of payment performance as sufficient to warrant a return to accrual status. For the three months ended March 31, 2016, the Company restructured $3,228 loans into troubled debt restructurings for which impairment was previously measured under the Company’s general loan loss allowance methodology. The types of modifications offered can generally be described in the following categories: Rate Modification - Term Modification - Interest-only Modification Combination Modification - Below is a table of the newly restructured loans identified in the three months ended March 31, 2016, and 2015.

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. In such cases of default, the Company takes appropriate action to recover principal and interest payments including the use of foreclosure proceedings. There were no TDRs that subsequently defaulted within the first twelve months of restructure during the periods ended March 31, 2016 and 2015. At March 31, 2016, and December 31, 2015, the Company had no commitments to lend additional funds on loans restructured as TDRs.

Dental Loan Portfolio

Dental Loan Portfolio	3 Months Ended

Dental Loan Portfolio	NOTE 4 – DENTAL LOAN PORTFOLIO Dental lending is not operated as a business segment, and dental loans are made in the normal course of commercial lending activities throughout the Company. However, to assist in understanding the concentrations and risks associated with the Company’s loan portfolio, the following Note has been included to provide additional information relating to the Company’s dental loan portfolio. At March 31, 2016 and December 31, 2015, loans to dental professionals totaled $350,940, and $340,162, respectively, and represented 24.52%, and 24.19% in principal amount of total outstanding loans, respectively. As of March 31, 2016 and December 31, 2015, dental loans were supported by government guarantees totaling $8,058 and $9,027, respectively. These guarantees represented 2.30%, and 2.65% in principal amount of the outstanding dental loan balances as of such respective dates. The Company defines a “dental loan” as a loan to dental professionals for the purpose of practice expansion, acquisition or other purpose supported by the cash flows of a dental practice. Loan Classification Major classifications of dental loans at March 31, 2016 and December 31, 2015, were as follows: March 31, December 31, Real estate secured loans: Owner-occupied commercial $ 58,669 $ 56,145 Other dental real estate loans 2,297 2,198 Total permanent real estate loans 60,966 58,343 Dental construction loans 3,493 4,334 Total real estate loans 64,459 62,677 Commercial loans 286,481 277,485 Gross loans $ 350,940 $ 340,162 Market Area The Bank’s defined “market area” is within the States of Oregon and Washington west of the Cascade Mountain Range. This area is serviced by branch locations in Eugene, Portland and Seattle. The Company also makes national dental loans throughout the United States, and currently has dental loans in 41 states, outside of Oregon and Washington. National loan relationships are maintained and serviced by Bank personnel primarily located in Portland. The following table summarizes the Company’s dental lending by borrower location: March 31, December 31, Local $ 149,698 $ 145,817 National 201,242 194,345 Total $ 350,940 $ 340,162 Allowance The allowance for loan losses identified for the dental loan portfolio is established as an amount that management considers adequate to absorb possible losses on existing loans within the dental portfolio. The allowance related to the dental loan portfolio consists of general and specific components. The general component is based upon all dental loans collectively evaluated for impairment, including qualitative conditions associated with: loan type, out-of-market location, start-up financing, practice acquisition financing, and specialty practice financing.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Share-Based Compensation	NOTE 7 – 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 subsidary. 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. For the three months ended March 31, 2016 and 2015, no equity awards were granted under the 2006 Stock Option and Equity Compensation Plan. The following table identifies the compensation expense recorded and tax benefits received by the Company on its share-based compensation plans for the three months ended March 31, 2016, and 2015: Three months ended March 31, 2016 2015 Compensation Tax Benefit Compensation Tax Benefit Equity-based awards: Employee RSUs $ 384 $ 146 $ 332 $ 126 The following table identifies stock options, employee stock SARs, and employee cash SARs exercised during the three months ended March 31, 2016 and 2015: Three months ended March 31, 2016 Number Weighted Intrinsic Number of Shares Issued Net Cash to Stock options 16,475 $ 12.73 $ 54 16,475 NA Employee stock SARs 6,265 $ 11.86 $ 4 995 NA Employee cash SARs 3,822 $ 13.43 NA NA $ 9 26,562 58 17,470 9 Three months ended March 31, 2015 Number Weighted Intrinsic Number of Shares Issued Net Cash Stock options 1,102 $ 12.25 $ 2 1,102 NA Employee stock SARs 613 $ 11.69 $ 1 — NA Employee cash SARs 208 $ 12.07 NA NA $ — 1,923 3 1,102 — At March 31, 2016, the Company had estimated unrecognized compensation expense of approximately $2,330 for unvested RSUs.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments	NOTE 8 – DERIVATIVE INSTRUMENTS The Bank purchases derivative instruments as a way to help mitigate interest rate risk. During the first 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 seven years at a rate of 2.73%. The derivative is designated as a cash flow hedge. The cash flow 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 March 31, 2016, was a $100 unrealized loss, which is recorded in accrued interest and other payables on the consolidated balance sheet. The Company pledged $400 under collateral arrangements to satisfy collateral requirements associated with the interest rate swap contract. The Bank maintains two interest rate swaps with commercial banking customers tied to loans on the consolidated balance sheet. Those interest rate swaps are simultaneously hedged by offsetting the interest rate swaps that the Bank executes with a first party, such that the Bank minimizes its net risk exposure. As of March 31, 2016, the Bank had non-hedge designated interest rate swaps with an aggregate notional amount of approximately $8,717 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 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 March 31, 2016 and December 31, 2015. The Bank entered into a swap with a third party to serve as a hedge to an equal amount of fixed rate loans. As of March 31, 2016 and December 31, 2015, the Bank had one swap designated a hedging instrument with a notional amount of $1,516 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 deferred fees. The following tables present quantitative information pertaining to the interest rate swaps as of March 31, 2016 and December 31, 2015: March 31, 2016 December 31, 2015 Hedge- Not-Hedge- Designated Hedge- Not-Hedge- Designated Notional amount $ 1,516 $ 8,717 $ 1,525 $ 8,774 Weighted average pay rate 5.71 % 4.85 % 5.71 % 4.85 % Weighted average receive rate 3.44 % 3.52 % 3.20 % 3.28 % Weighted average maturity in years 7.35 6.24 7.6 6.49 The following table presents the fair values of derivative instruments and their locations in the consolidated balance sheets as of March 31, 2016 and December 31, 2015: Asset Derivatives Liability Derivatives Derivative Balance sheet location March 31, December 31, March 31, December 31, Cash flow hedge Other assets or other payables $ — $ 82 $ 100 $ — Interest rate swap designated as hedging instrument Other assets or other payables 114 66 143 93 Interest rate swap not designated as hedging instrument Other assets or other payables 148 24 148 24 $ 262 $ 172 $ 391 $ 117 The following table presents the income statement impact of the derivative instruments for the period ended March 31, 2016 and 2015: Three months ended Income statement March 31, Derivative location 2016 2015 Cash flow hedge Other noninterest income $ — $ — Interest rate swap designated as hedging instrument Other noninterest income 1 5 Interest rate swap not designated as hedging instrument Other noninterest income — — $ 1 $ 5

Deposits Federal Home Loan Bank borrowings Junior subordinated debentures 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 and carried at fair value as of March 31, 2016 and December 31, 2015: Carrying Fair Value at March 31, 2016 Level 1 Level 2 Level 3 Financial assets: Cash and cash equivalents $ 54,459 $ 54,459 $ — $ — Loans, net of deferred fees 1,429,734 — — 1,417,537 Interest receivable 6,003 6,003 — — Federal Home Loan Bank stock 3,511 3,511 — — Bank-owned life insurance 23,030 23,030 — — Interest rate swaps 262 262 — — Financial liabilities: Deposits $ 1,696,588 $ 1,563,169 $ 133,476 $ — Federal Home Loan Bank borrowings 30,500 — 30,797 — Junior subordinated debentures 8,248 — 2,787 — Interest payable 156 156 — — Interest rate swaps 391 391 — — Carrying 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 172 172 — — Financial liabilities: Deposits $ 1,597,093 $ 1,458,490 $ 138,790 $ — Federal Home Loan Bank borrowings 77,500 — 77,651 — Junior subordinated debentures 8,248 — 2,741 — Accrued interest payable 138 138 — — Interest rate swaps 117 117 — — The tables below show assets (liabilities) measured at fair value on a recurring basis as of March 31, 2016 and December 31, 2015: Carrying Fair Value at March 31, 2016 Value Level 1 Level 2 Level 3 Financial Assets Available-for-sale securities Obligations of U.S. government agencies $ 35,599 $ — $ 35,599 $ — Obligations of states and political subdivisions 99,844 — 99,844 — Agency mortgage-backed securities 204,891 — 204,891 — Private-label mortgage-backed securities 2,576 — 1,055 1,521 SBA pools 39,641 — 39,641 — Corporate securities 891 — 891 — Interest rate swaps 262 262 — — Total assets measured on a recurring basis $ 383,704 $ 262 $ 381,921 $ 1,521 Financial Liabilities Interest rate swap liabilities measured on a recurring basis $ 391 $ 391 $ — $ — Carrying Fair Value at December 31, 2015 Value Level 1 Level 2 Level 3 Available-for-sale securities Obligations of U.S. government agencies $ 44,623 $ — $ 44,623 $ — Obligations of states and political subdivisions 97,151 — 97,151 — Agency mortgage-backed securities 185,370 — 185,370 — Private-label mortgage-backed securities 2,789 — 1,203 1,586 SBA pools 35,772 — 35,772 — Corporate securities 893 — 893 — Interest rate swaps 172 172 — — Total assets measured on a recurring basis $ 366,770 $ 172 $ 365,012 $ 1,586 Financial Liabilities Interest rate swap liabilities measured on a recurring basis $ 117 $ 117 $ — $ — No transfers to or from Levels 1 and 2 occurred on assets and liabilities measured at fair value on a recurring basis during the three months ended March 31, 2016, or during the year ended December 31, 2015. The following is a description of the inputs and valuation methodologies used for assets and liabilities recorded at fair value on a recurring basis. Fair value for all classes of available-for-sale securities and derivative instruments are 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 private-label mortgage-backed securities measured at fair value on a recurring basis using unobservable inputs (Level 3) for the three months ended March 31, 2016, and 2015: Three months ended 2016 2015 Beginning balance $ 1,586 $ 1,568 Transfers into level 3 — — Transfers out of Level 3 — — Total gains or losses Included in earnings — — Included in other comprehensive income 13 13 Paydowns (78 ) (37 ) Purchases, issuances, sales and settlements Purchases — — Issuances — — Sales — — Settlements — — Ending balance $ 1,521 $ 1,544 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 first-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 first-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 first-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 first-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 March 31, 2016 and December 31, 2015: Carrying Fair Value March 31, 2016 Value Level 1 Level 2 Level 3 Loans measured for impairment (net of government guarantees and specific reserves) $ — $ — $ — $ — Other real estate owned — — — — Total $ — $ — $ — $ — Carrying Fair Value December 31, 2015 Value Level 1 Level 2 Level 3 Loans measured for impairment (net of government guarantees and specific reserves) $ 53 $ — $ — $ 53 Other real estate owned 10,147 — — 10,147 Total $ 10,200 $ — $ — $ 10,200 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 10 – 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 capital, Tier 1 capital, common equity Tier 1 to risk-weighted assets and, Tier 1 capital to leverage assets. Management believes that, as of March 31, 2016, the Company and the Bank met all capital adequacy requirements to which they were subject. As of March 31, 2016, and according to Federal Reserve and FDIC guidelines, the Bank was considered to be well-capitalized. To be categorized as well-capitalized, the Bank must maintain minimum Total capital, Tier 1 capital, common equity Tier 1 to risk-weighted assets and, Tier 1 capital to leverage assets ratios as set forth in the following table.

Subsequent Events [Abstract]
Subsequent Events	NOTE 11 – SUBSEQUENT EVENTS On April 26, 2016, the Bank announced the signing of a definitive agreement to acquire Foundation Bank, a state chartered bank headquartered in Bellevue, Washington. Under the terms of the agreement, which has been unanimously approved by the boards of directors of Pacific Continental Corporation, Pacific Continental Bank, Foundation Bancorp, Inc. and Foundation Bank, the shareholders of Foundation may elect to receive either 0.7911 shares of the Company’s common stock, $12.50 per share in cash or a combination thereof, for each share of Foundation common stock. The preferred stock of Foundation will become convertible into the right to receive the merger consideration with respect to 1,500,000 shares of Foundation Bancorp, Inc. common stock, together with cumulative cash dividends payable to such holders. As of the announcement date the aggregate consideration for Foundation was approximately $67.1 million, or $13.02 per share. The number of shares of the Company’s common stock to be issued to Foundation shareholders is based on a fixed exchange ratio. The value of the stock portion of the consideration will fluctuate based on the value of the Company’s common stock. To the extent there are under or over subscriptions for cash election shares by Foundation shareholders, under the terms of the merger agreement there will be a re-allocation of the merger consideration for such Foundation shareholders such that the aggregate cash consideration shall equal approximately $19.3 million. Completion of the transaction is subject to customary closing conditions, including bank regulatory approvals and approval of Foundation Bank’s shareholders. The transaction is expected to close in the third quarter of 2016.

Accounting Policies [Abstract]
Basis of Presentation	The accompanying consolidated financial statements have been prepared by the Company without audit and in conformity with generally accepted accounting principles in the United States of America for interim financial information. The consolidated financial statements include all adjustments and normal accruals, which the Company considers necessary for a fair presentation of the results of operations for such interim periods. In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities, as of the date of the balance sheets and income and expenses for the periods. Actual results could differ from those estimates. The balance sheet data as of December 31, 2015, was derived from audited consolidated financial statements, but does not include all disclosures contained in the Company’s 2015 Form 10-K. The interim consolidated financial statements should be read in conjunction with the December 31, 2015, consolidated financial statements, including the notes thereto, included in the Company’s 2015 Form 10-K.
Loans	Loans are stated at the amount of unpaid principal net of loan premiums or discounts for purchased loans, net of 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	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.
Fair Value Measurements	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.
