Share-based Compensation [Abstract]
Share Based Compensation	Note 5 – Share Based Compensation The 2007 Stock Incentive Plan (the “2007 Plan”) was adopted by the Company in 2007. Our 1998 Stock Option Plan was concurrently terminated, although options to purchase 28,500 1,500,000 748,420 10 Pursuant to FASB’s standards on stock compensation, the value of each stock option granted is reflected in our income statement as employee compensation or directors’ expense by amortizing the value over the vesting period for options with graded vesting, or by expensing it as of the grant date for immediately vested options. The Company is utilizing the Black-Scholes model to value stock options, and the “multiple option” approach is used to allocate the resulting valuation to actual expense. Under the multiple option approach an employee’s options for each vesting period are separately valued and amortized, which appears to be the preferred method for option grants with graded vesting.

Financial Instruments With Off Balance Sheet Risk [Abstract]
Financial Instruments with Off-Balance-Sheet Risk	Note 8 – Financial Instruments with Off-Balance-Sheet Risk The Company is a party to financial instruments with off-balance-sheet risk in the normal course of business. Those financial instruments currently consist of unused commitments to extend credit and standby letters of credit. They involve, to varying degrees, elements of risk in excess of the amount recognized in the balance sheet. The Company’s exposure to credit loss in the event of nonperformance by counterparties for commitments to extend credit and letters of credit is represented by the contractual amount of those instruments. The Company uses the same credit policies in making commitments and issuing letters of credit as it does for originating loans included on the balance sheet. September 30, 2016 December 31, 2015 Commitments to extend credit $ 399,273 $ 354,890 Standby letters of credit $ 8,456 $ 16,654 Commitments to extend credit consist primarily of the unused or unfunded portions of the following: home equity lines of credit; commercial real estate construction loans, where disbursements are made over the course of construction; commercial revolving lines of credit; mortgage warehouse lines of credit; unsecured personal lines of credit; and formalized (disclosed) deposit account overdraft lines. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many commitments are expected to expire without being drawn upon, the unused portions of committed amounts do not necessarily represent future cash requirements. Standby letters of credit are generally unsecured and are issued by the Company to guarantee the performance of a customer to a third party, and the credit risk involved in issuing letters of credit is essentially the same as the risk involved in extending loans to customers. At September 30, 2016, the Company was also utilizing a letter of credit in the amount of $ 97

Fair Value Disclosures [Abstract]
Fair Value Disclosures and Reporting, the Fair Value Option and Fair Value Measurements	Note 9 – Fair Value Disclosures and Reporting, the Fair Value Option and Fair Value Measurements FASB’s standards on financial instruments, and on fair value measurements and disclosures, require all entities to disclose in their financial statement footnotes the estimated fair values of financial instruments for which it is practicable to estimate fair values. In addition to disclosure requirements, FASB’s standard on investments requires that our debt securities which are classified as available for sale and our equity securities that have readily determinable fair values be measured and reported at fair value in our statement of financial position. Certain impaired loans are also reported at fair value, as explained in greater detail below, and foreclosed assets are carried at the lower of cost or fair value. FASB’s standard on financial instruments permits companies to report certain other financial assets and liabilities at fair value, but we have not elected the fair value option for any of those financial instruments. Fair value measurement and disclosure standards also establish a framework for measuring fair values. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability, in an orderly transaction between market participants on the measurement date. Further, the standards establish a fair value hierarchy that encourages an entity to maximize the use of observable inputs and limit the use of unobservable inputs when measuring fair values. The standards describe three levels of inputs that may be used to measure fair values: ⋅ Level 1 ⋅ Level 2 ⋅ Level 3 Fair value estimates are made at a specific point in time based on relevant market data and information about the financial instruments. The estimates do not reflect any premium or discount that could result from offering the Company’s entire holdings of a particular financial instrument for sale at one time, nor do they attempt to estimate the value of anticipated future business related to the instruments. In addition, the tax ramifications related to realized gains and losses could have a significant effect on fair value estimates but have not been considered in those estimates. Because no active market exists for a significant portion of our financial instruments, fair value disclosures are based on judgments regarding current economic conditions, risk characteristics of various financial instruments and other factors. The estimates are subjective and involve uncertainties and matters of significant judgment, and therefore cannot be determined with precision. Changes in assumptions could significantly alter the fair values presented. The following methods and assumptions were used by the Company to estimate its financial instrument fair values disclosed at September 30, 2016 and December 31, 2015: ⋅ Cash and cash equivalents and fed funds sold ⋅ Investment securities ⋅ Loans and leases ⋅ Loans held for sale ⋅ Collateral-dependent impaired loans ⋅ Cash surrender value of life insurance policies ⋅ Investments in, and capital commitments to, limited partnerships ⋅ Other investments ⋅ Deposits ⋅ Short-term borrowings ⋅ Long-term borrowings ⋅ Subordinated debentures ⋅ Commitments to extend credit and letters of credit Estimated fair values for the Company’s financial instruments are as follows, as of the dates noted: (dollars in thousands, unaudited) September 30, 2016 Estimated Fair Value Carrying Quoted Prices in Significant Significant Total Financial assets: Cash and cash equivalents $ 65,442 $ 65,537 $ -

Information on the Company’s total impaired loan balances and specific loss reserves associated with those balances is included in Note 11 below, and in Management’s Discussion and Analysis of Financial Condition and Results of Operation in the “Nonperforming Assets” and “Allowance for Loan and Lease Losses” sections. The unobservable inputs are based on Management’s best estimates of appropriate discounts in arriving at fair market value. Increases or decreases in any of those inputs could result in a significantly lower or higher fair value measurement. For example, an increase or decrease in actual loss rates would create a directionally opposite change in the fair value of unsecured impaired loans.

Investments, Debt and Equity Securities [Abstract]
Investments in Debt and Marketable Equity Securities (and Certain Trading Assets) Disclosure	Note 10 – Investments Investment Securities Although the Company currently has the intent and the ability to hold the securities in its investment portfolio to maturity, the securities are all marketable and are classified as “available for sale” to allow maximum flexibility with regard to interest rate risk and liquidity management. Pursuant to FASB’s guidance on accounting for debt and equity securities, available for sale securities are carried on the Company’s financial statements at their estimated fair market values, with monthly tax-effected “mark-to-market” adjustments made vis-à-vis accumulated other comprehensive income in shareholders’ equity.

The tax credits flow through to investors, supplementing any returns that might be derived from an increase in property values. Because rent levels are lower than standard market rents and the projects are generally highly leveraged, each project also typically generates tax-deductible operating losses that are allocated to the limited partners. The Company invested in seven LIHTC fund limited partnerships from 2001 through 2007, and in the second quarter of 2016 we committed $ 3 As of September 30, 2016 our total LIHTC investment balance was $ 7.1 2.1 515,000 788,000

OREO consists of real properties acquired by foreclosure or similar means, which the Company is offering or will offer for sale. Nonperforming loans and leases result when reasonable doubt surfaces with regard to the ability of the Company to collect all principal and interest. At that point, we stop accruing interest on the loan or lease in question and reverse any previously-recognized interest to the extent that it is uncollected or associated with interest-reserve loans. Any asset for which principal or interest has been in default for 90 days or more is also placed on non-accrual status even if interest is still being received, unless the asset is both well secured and in the process of collection.

The company had no finance receivables modified as TDRs within the previous twelve months that defaulted or were charged off during the three month or nine month periods ended September 30, 2016 and 2015 respectively. Purchased Credit Impaired Loans The Company may acquire loans which show evidence of credit deterioration since origination. These purchased credit impaired (“PCI”) loans are recorded at the amount paid, since there is no carryover of the seller’s allowance for loan losses. Potential losses on PCI loans subsequent to acquisition are recognized by an increase in the allowance for loan losses. PCI loans are accounted for individually or are aggregated into pools of loans based on common risk characteristics. The Company estimates the amount and timing of expected cash flows, and expected cash receipts in excess of the amount paid for the loan(s) are recorded as interest income over the remaining life of the loan or pool of loans (accretable yield). The excess of contractual principal and interest over expected cash flows is not recorded (nonaccretable difference). Expected cash flows are periodically re-evaluated throughout the life of the loan or pool of loans. If the present value of the expected cash flows is determined at any time to be less than the carrying amount, a reserve is recorded. If the present value of the expected cash flows is greater than the carrying amount, it is recognized as part of future interest income. Our acquisitions of Santa Clara Valley Bank in the fourth quarter of 2014 and Coast in the third quarter of 2016 included certain loans which have shown evidence of credit deterioration since origination, and for which it was probable at acquisition that all contractually required payments would not be collected.

Provision for Loan and Lease Losses [Abstract]
Allowance for Loan and Lease Losses	Note 12 – Allowance for Loan and Lease Losses The Company’s allowance for loan and lease losses, a contra-asset, is established through a provision for loan and lease losses. The allowance is maintained at a level that is considered adequate to absorb probable losses on certain specifically identified loans, as well as probable incurred losses inherent in the remaining loan portfolio. Specifically identifiable and quantifiable losses are immediately charged off against the allowance; recoveries are generally recorded only when cash payments are received subsequent to the charge off. We employ a systematic methodology, consistent with FASB guidelines on loss contingencies and impaired loans, for determining the appropriate level of the allowance for loan and lease losses and adjusting it at least quarterly. Pursuant to that methodology, impaired loans and leases are individually analyzed and a criticized asset action plan is completed specifying the financial status of the borrower and, if applicable, the characteristics and condition of collateral and any associated liquidation plan. A specific loss allowance is created for each impaired loan, if necessary. The following tables disclose the unpaid principal balance, recorded investment, average recorded investment, and interest income recognized for impaired loans on our books as of the dates indicated. Balances are shown by loan type, and are further broken out by those that required an allowance and those that did not, with the associated allowance disclosed for those that required such. Included in the valuation allowance for impaired loans shown in the tables below are specific reserves allocated to TDRs, totaling $ 1.460 1.486 (dollars in thousands, unaudited) September 30, 2016 Average Unpaid Principal Recorded Related Recorded Interest Income Balance (1) Investment (2) Allowance Investment Recognized (3) With an allowance recorded Real Estate: Other construction/land 273 $ 237 $ 15 $ 295 $ 11 1-4 Family - closed-end 8,025 6,078 206 8,116 335 Equity lines 3,551 3,466 193 3,645 48 Multi-family residential 413 413 6 422 33 Commercial real estate- owner occupied 1,366 1,366 508 1,793 135 Commercial real estate- non-owner occupied 1,899 1,751 36 1,977 99 Farmland - - - - - Total real estate 15,527 13,311 964 16,248 661 Agriculture 24 24 24 24 - Commercial and industrial 1,942 1,942 505 2,190 72 Consumer loans 1,730 1,730 297 1,907 76 19,223 17,007 1,790 20,369 809 With no related allowance recorded Real estate: Other construction/land 984 865 - 1,457 21 1-4 family - closed-end 669 608 - 687 2 Equity lines 569 540 - 583 - Multi-family residential - - - - - Commercial real estate- owner occupied 1,138 1,138 - 2,480 - Commercial real estate- non-owner occupied 79 69 - 278 - Farmland 295 295 - 100 - Total real estate 3,734 3,515 - 5,585 23 Agriculture 65 65 - 65 - Commercial and industrial 207 205 - 386 1 Consumer loans 141 17 - 226 - 4,147 3,802 - 6,262 24 Total $ 23,370 $ 20,809 $ 1,790 $ 26,631 $ 833 (1) Contractual principal balance due from customer.

(2) Principal balance on Company’s books, less any direct charge offs. (3) Interest income is recognized on performing balances on a regular accrual basis. The specific loss allowance for an impaired loan generally represents the difference between the book value of the loan and either the fair value of underlying collateral less estimated disposition costs, or the loan’s net present value as determined by a discounted cash flow analysis. The discounted cash flow approach is typically used to measure impairment on loans for which it is anticipated that repayment will be provided from cash flows other than those generated solely by the disposition or operation of underlying collateral. However, historical loss rates may be used to determine a specific loss allowance if they indicate a higher potential reserve need than the discounted cash flow analysis. Any change in impairment attributable to the passage of time is accommodated by adjusting the loss allowance accordingly. For loans where repayment is expected to be provided by the disposition or operation of the underlying collateral, impairment is measured using the fair value of the collateral. If the collateral value, net of the expected costs of disposition where applicable, is less than the loan balance, then a specific loss reserve is established for the shortfall in collateral coverage. If the discounted collateral value is greater than or equal to the loan balance, no specific loss reserve is required. At the time a collateral-dependent loan is designated as nonperforming, a new appraisal is ordered and typically received within 30 to 60 days if a recent appraisal is not already available. We generally use external appraisals to determine the fair value of the underlying collateral for nonperforming real estate loans, although the Company’s licensed staff appraisers may update older appraisals based on current market conditions and property value trends. Until an updated appraisal is received, the Company uses the existing appraisal to determine the amount of the specific loss allowance that may be required. The specific loss allowance is adjusted, as necessary, once a new appraisal is received. Updated appraisals are generally ordered at least annually for collateral-dependent loans that remain impaired. Current appraisals were available or in process for 93 Our methodology also provides for the establishment of a “general” allowance for probable incurred losses inherent in loans and leases that are not impaired. Unimpaired loan balances are segregated by credit quality, and are then evaluated in pools with common characteristics. At the present time, pools are based on the same segmentation of loan types presented in our regulatory filings. While this methodology utilizes historical loss data and other measurable information, the credit classification of loans and the establishment of the allowance for loan and lease losses are both to some extent based on Management’s judgment and experience. Our methodology incorporates a variety of risk considerations, both quantitative and qualitative, in establishing an allowance for loan and lease losses that Management believes is appropriate at each reporting date. Quantitative information includes our historical loss experience, delinquency and charge-off trends, and current collateral values. Qualitative factors include the general economic environment in our markets and, in particular, the condition of the agricultural industry and other key industries. Lending policies and procedures (including underwriting standards), the experience and abilities of lending staff, the quality of loan review, credit concentrations (by geography, loan type, industry and collateral type), the rate of loan portfolio growth, and changes in legal or regulatory requirements are additional factors that are considered. The total general reserve established for probable incurred losses on unimpaired loans was $ 8.090 There were no material changes to the methodology used to determine our allowance for loan and lease losses during the three months ended September 30, 2016, although in recognition of relatively low loan loss rates in recent periods upward adjustments were made to the ranges for qualitative factor multipliers. We continue to consider the estimated impact of drought conditions and lower oil prices on credit quality, in evaluating the adequacy of our allowance. As we add new products and expand our geographic coverage, and as the economic environment changes, we expect to enhance our methodology to keep pace with the size and complexity of the loan and lease portfolio and respond to pressures created by external forces. We engage outside firms on a regular basis to assess our methodology and perform independent credit reviews of our loan and lease portfolio. In addition, the Company’s external auditors, the FDIC, and the California DBO review the allowance for loan and lease losses as an integral part of their audit and examination processes. Management believes that the current methodology is appropriate given our size and level of complexity.
