Accounting Policies [Abstract]

The Company and Summary of Significant Accounting Policies

FNB Bancorp (the “Company”) is a bank holding company registered under the Bank Holding Company Act of 1956, as amended. The Company was incorporated under the laws of the State of California on February 28, 2001. The consolidated financial statements include the accounts of FNB Bancorp and its wholly-owned subsidiary, First National Bank of Northern California (the “Bank”). The Bank provides traditional banking services in San Mateo, San Francisco and Santa Clara Counties, and operates a loan production office in Santa Clara County.

The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and revenue and expenses during the reporting period. Actual results could differ from those estimates. The significant accounting estimates are the allowance for loan losses, the valuation of goodwill, the valuation of the allowance for deferred tax assets and fair value determinations such as OREO and impaired loans. A summary of the significant accounting policies applied in the preparation of the accompanying consolidated financial statements follows.

(a)

Basis of Presentation

The accounting and reporting policies of the Company and its wholly-owned subsidiary are in accordance with accounting principles generally accepted in the United States of America. All intercompany balances and transactions have been eliminated.

(b)

Cash and Cash Equivalents

Cash and cash equivalents include cash on hand, amounts due from banks, and federal funds sold. Generally, federal funds are sold for one-day periods. The cash equivalents are readily convertible to known amounts of cash and present insignificant risk of changes in value due to original maturity dates of 90 days or less. Included in cash and cash equivalents are restricted balances at the Federal Reserve Bank of San Francisco which relate to a minimum cash reserve requirement of approximately $1,189,000 and $1,278,000 at December 31, 2014 and 2013, respectively.

(c)

Investment Securities

Investment securities consist of U.S. Treasury securities, U.S. agency securities, obligations of states and political subdivisions, obligations of U.S. corporations, mortgage-backed securities and other securities. At the time of purchase of a security, the Company designates the security as held-to-maturity or available-for-sale, based on its investment objectives, operational needs, and intent to hold. The Company classifies securities as held to maturity only if and when it has the positive intent and ability to hold the security to maturity. The Company does not purchase securities with the intent to engage in trading activity. Held to maturity securities are recorded at amortized cost, adjusted for amortization of premiums or accretion of discounts.

The Company did not have any investments in the held-to-maturity portfolio at December 31, 2014 or 2013. Securities available-for-sale are recorded at fair value with unrealized holding gains or losses, net of the related tax effect, reported as a separate component of stockholders’ equity until realized.

An impairment charge will be recorded if the Company has the intent to sell a security that is currently in an unrealized loss position or where the Company may be required to sell a security that is currently in an unrealized loss position. A decline in the fair value of any security available-for-sale or held-to-maturity below cost that is deemed other than temporary will cause a charge to earnings to be recorded and the corresponding establishment of a new cost basis for the security. Amortization of premiums and accretion of discounts on debt securities are included in interest income over the life of the related security held-to-maturity or available-for-sale using the effective interest method. Dividend and interest income are recognized when earned. Realized gains and losses for securities classified as available-for-sale and held-to-maturity are included in earnings and are derived using the specific identification method for determining the cost of securities sold.

Investments with fair values that are less than amortized cost are considered impaired. Impairment may result from either a decline in the financial condition of the issuing entity or, in the case of fixed interest rate investments, from rising interest rates. At each consolidated financial statement date, management assesses each investment to determine if impaired investments are temporarily impaired or if the impairment is other than temporary. This assessment includes a determination of whether the Company intends to sell the security, or if it is more likely than not that the Company will be required to sell the security before recovery of its amortized cost basis less any current-period credit losses. For debt securities that are considered other than temporarily impaired and that the Company does not intend to sell and will not be required to sell prior to recovery of the amortized cost basis, the amount of impairment is separated into the amount that is credit related (credit loss component) and the amount due to all other factors. The credit loss component is recognized in earnings and is calculated as the difference between the security’s amortized cost basis and the present value of its expected future cash flows. The remaining difference between the security’s fair value and the present value of the future expected cash flows is deemed to be due to factors that are not credit related and is recognized in other comprehensive earnings.

(d)

Derivatives

All derivatives contracts and instruments are recognized as either assets or liabilities in the balance sheet and measured at fair value. The Company did not hold any derivative contracts at December 31, 2014 or 2013.

(e)

Loans

Loans are reported at the principal amount outstanding, net of deferred loan fees and the allowance for loan losses. An unearned discount on installment loans is recognized as income over the terms of the loans by the interest method. Interest on other loans is calculated by using the simple interest method on the daily balance of the principal amount outstanding. Loan fees net of certain direct costs of origination, which represent an adjustment to interest yield, are deferred and amortized over the contractual term of the loan using the interest method.

Loans on which the accrual of interest has been discontinued are designated as nonaccrual loans. Accrual of interest on loans is discontinued either when reasonable doubt exists as to the full and timely collection of interest or principal when a loan becomes contractually past due by 90 days or more with respect to interest or principal. When a loan is placed on nonaccrual status, all interest previously accrued but not collected is reversed against current period interest income. Interest accruals are resumed on such loans only when they are brought fully current with respect to interest and principal and when, in the judgment of management, the loans are estimated to be fully collectible as to both principal and interest.

A loan is considered impaired if, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due, according to the contractual terms of the loan agreement. An impaired loan is measured based upon the present value of future cash flows discounted at the loan’s effective rate, the loan’s observable market price, or the fair value of collateral if the loan is collateral dependent. Interest on impaired loans is recognized on a cash basis. If the measurement of the impaired loan is less than the recorded investment in the loan, an impairment is recognized by a charge to the allowance for loan losses. Large groups of smaller balance loans are collectively evaluated for impairment.

Restructured loans are loans on which concessions in terms have been granted because of the borrowers’ financial difficulties. Interest is generally accrued on such loans in accordance with the new terms, once the borrower has demonstrated a history of at least six months repayment. A loan is considered to be a troubled debt restructuring when the Company, for economic or legal reasons related to the debtor’s financial difficulties grants a concession to the debtor that makes it easier for the debtor to make their required loan payments. The concession may take the form of a temporary reduction in the interest rate or monthly payment amount due or may extend the maturity date of the loan. Other financial concessions may be agreed to as conditions warrant. Troubled debt restructured loans are accounted for as impaired loans. For an impaired loan that has been restructured, the contractual terms of the loan agreement refer to the contractual terms specified by the original loan agreement, not the contractual terms specified by the restructuring agreement.

Loans acquired in business combinations are recorded on a loan-by-loan basis at their estimated fair value. The Company uses third party valuation specialists to determine the estimated fair value on all acquired loans. The Company acquires both performing and impaired loans (loans acquired with evidence of credit quality deterioration at the time of purchase) in its acquisitions. For acquired performing loans, any discount or premium related to fair value adjustments at the time of purchase is recognized as interest income over the estimated life of the loan using the effective yield method. Loans acquired with evidence of credit quality deterioration, at the time of purchase, are accounted for under ASC 310-30 Loans and Debt Securities Acquired with Deteriorated Credit Quality (“ASC 310-30 Loans”). For ASC 310-30 loans, the excess of cash flows expected to be collected over a loan’s carrying value is considered to be the accretable yield and is recognized as interest income over the estimated life of the loan using the effective yield method. The acquisition date estimates of accretable yield may subsequently change due to changes in management’s estimates of timing and amounts of expected cash flows.

The excess of the contractual amounts due over the cash flows expected to be collected is considered to be the nonaccretable difference. The nonaccretable difference represents the Company’s estimate of the credit losses expected to occur and is considered in determining the fair value of the loans as of the acquisition date. Subsequent to the acquisition date, any increases in expected cash flows over those expected at acquisition date in excess of fair value are adjusted through an increase to the accretable yield on a prospective basis. Any subsequent decreases in cash flows attributable to credit deterioration are recognized by recording additional provision for loan losses.

(f)

Allowance for Loan Losses

The allowance for loan losses is established through a provision for loan losses charged to expense. Loans are charged off against the allowance for loan losses when management believes that the collectability of the principal is unlikely. The allowance is an amount that management believes will be adequate to absorb probable losses inherent in existing loans, standby letters of credit, overdrafts, and commitments to extend credit based on evaluations of collectability and prior loss experience. The evaluations take into consideration such factors as changes in the nature and volume of the portfolio, overall portfolio quality, loan concentrations, specific problem loans and current and anticipated economic conditions that may affect the borrowers’ ability to pay. While management uses these evaluations to determine the level of the allowance for loan losses, future provisions may be necessary based on changes in the factors used in the evaluations. Material estimates relating to the determination of the allowance for loan losses are particularly susceptible to significant change in the near term. Management believes that the allowance for loan losses is adequate as of December 31, 2014. While management uses available information to recognize losses on loans, future additions to the allowance may be necessary based on changes in economic conditions, and our borrowers’ ability to pay. In addition, the banking regulators, as an integral part of its examination process, periodically review the Bank’s allowance for loan losses. The banking regulators may require the Bank to recognize additions to the allowance based on their judgment about information available to them at the time of their examination.

(g)

Premises and Equipment

Premises and equipment are reported at cost less accumulated depreciation using the straight-line method over the estimated service lives of related assets ranging from 3 to 50 years. Leasehold improvements are amortized over the estimated lives of the respective leases or the service lives of the improvements, whichever is shorter.

(h)

Other Real Estate Owned

Real estate properties acquired through, or in lieu of, loan foreclosure are to be sold and are initially recorded at the lower of the carrying amount of the loan or fair value of the property at the date of foreclosure less selling costs. Subsequent to foreclosure, valuations are periodically performed, and any subsequent revisions in the estimate of fair value are reported as an adjustment to the carrying value of the real estate, provided the adjusted carrying amount does not exceed the original amount at foreclosure. Revenues and expenses from operations and changes in the valuation allowance are included in other operating expenses.

The Company may make loans to facilitate the sale of foreclosed real estate. Gains and losses on financed sales are recorded in accordance with the appropriate accounting standard, taking into account the buyer’s initial and continuing investment in the property, potential subordination and transfer of ownership.

(i)

Goodwill and Other Intangible Assets

Goodwill is recognized in a business acquisition transaction when the acquisition purchase price exceeds the fair value of identified tangible and intangible assets and liabilities. Goodwill is subsequently evaluated for possible impairment at least annually. If impairment is determined to exist, it is recorded in the period it is identified. The Company evaluated goodwill at December 31, 2014 and found no impairment.

Other intangible assets consist of core deposit and customer intangible assets that are initially recorded at fair value and subsequently amortized over their estimated useful lives, usually no longer than a seven year period.

(j)

Cash Dividends

The Company’s ability to pay cash dividends is subject to restrictions set forth in the California General Corporation Law. Funds for payment of any cash dividends by the Company would be obtained from its investments as well as dividends and/or management fees from the Bank. The Bank’s ability to pay cash dividends is also subject to restrictions imposed under the National Bank Act and regulations promulgated by the Office of the Comptroller of the Currency.

(k)

Stock Dividend

On November 17, 2014, the Company announced that its Board of Directors had declared a five percent (5%) stock dividend which resulted in approximately 202,505 shares, payable at the rate of one share of Common Stock for every twenty (20) shares of Common Stock owned. The stock dividend was paid on January 16, 2015, to stockholders of record on December 15, 2014. The earnings per share data for all periods presented have been adjusted for stock dividends. However, the Consolidated Statement of Changes in Stockholders’ Equity shows the historical rollforward of stock options declared.

Income Taxes

Deferred income taxes are determined using the asset and liability method. Under this method, the net deferred tax asset or liability is recognized for tax consequences of temporary differences by applying current tax rates to differences between the financial reporting and the tax basis of existing assets and liabilities. Deferred tax assets and liabilities are reflected at currently enacted income tax rates applicable to the period in which the deferred tax assets or liabilities are expected to be realized or settled. A valuation allowance is established through the provision for income taxes for any deferred tax assets where the utilization of the asset is in doubt. During 2013, the Company recorded a reversal of the deferred tax asset valuation allowance of $934,000 for tax credit carry-forwards from the Bank’s investment in low income housing real estate partnerships. As changes in tax laws or rates are enacted, or as significant changes financial projections, deferred tax assets and liabilities are adjusted through the provision for income taxes.

The Company had unrecognized tax benefits of $718,000 as of December 31, 2014 and 2013, respectively. These unrecognized tax benefits are related to income tax uncertainties surrounding the Bank’s Enterprise Zone net interest deduction. The Bank is currently being audited by the Franchise Tax Board for the years ended December 31, 2005 through 2008, and the outcome of these audits is uncertain.

The Company recognizes interest accrued and penalties related to unrecognized tax benefits in tax expense. During the years ended December 31, 2014 and 2013, the Company believes that any penalties and interest penalties that may exist are not material and the Company has not accrued for them.

At December 31, 2014, the Bank had a $2,331,000 investment in five partnerships, which own low-income affordable housing projects that generate tax benefits in the form of federal and state housing tax credits. As a limited partner investor in these partnerships, the Company receives tax benefits in the form of tax deductions from partnership operating losses and federal and state income tax credits.

The federal and state income tax credits are earned over a 10-year period as a result of the investment properties meeting certain criteria and are subject to recapture for noncompliance with such criteria over a 15-year period.

The expected benefit resulting from the low-income housing tax credits is recognized in the period for which the tax benefit is recognized in the Company’s consolidated tax returns. These investments are accounted for using the historical cost method less depreciation and amortization and are recorded in other assets on the balance sheet. The Company recognizes tax credits as they are allocated and amortizes the initial cost of the investments over the period that tax credits are allocated to the Company. There is no residual value for the investment at the end of the tax credit allocation period. Cash received from operations of the limited partnership or sale of the properties, if any, will be included in earnings when realized.

(o)

Earnings per Share

Earnings per common share (EPS) are computed based on the weighted average number of common shares outstanding during the period. Basic EPS excludes dilution and is computed by dividing net earnings available to common stockholders (after deducting dividends and related accretion on preferred stock) by the weighted average of common shares outstanding. Diluted EPS reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock. The number of potential common shares included in the quarterly diluted EPS is computed using the average market price during the three months included in the reporting period under the treasury method. The number of potential common shares included in year-to-date diluted EPS is a year-to-date weighted average of potential shares included in each quarterly diluted EPS computation. All common stock equivalents are anti-dilutive when a net loss occurs. A 5% stock dividend was declared in the fourth quarter of 2014, and prior per share amounts have been adjusted to reflect the 5% stock dividend.

Stock Option Plans

Measurement of the cost of stock options granted is based on the grant-date fair value of each stock option granted using the Black-Scholes valuation model. The cost is then amortized to expense on a straight-line basis over each option’s requisite service period. The amortized expense of the stock option’s fair value has been included in salaries and employee benefits expense on the consolidated statements of earnings for the three years ended December 31, 2014, 2013 and 2012. The expected term of options granted is derived from the output of the option valuation model and represents the period of time that options granted are expected to be outstanding. The risk-free rate for periods within the expected term of the option is based on the U. S. Treasury yield curve in effect at the time of the grant. The Company’s stock has limited liquidity and limited trading activity. Volatility was calculated using historical price changes on a monthly basis over the expected life of the option.

(q)

Fair Values of Financial Instruments

The accounting standards provide for a fair value measurement framework that quantifies fair value estimates by the level of pricing precision. The degree of judgment utilized in measuring the fair value of assets generally correlates to the level of pricing precision. Financial instruments rarely traded or not quoted will generally have a higher degree of judgment utilized in measuring fair value. Pricing precision is impacted by a number of factors including the type of asset or liability, the availability of the asset or liability, the market demand for the asset or liability, and other conditions that were considered at the time of the valuation.

In general, fair values determined by Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access. Level 2 inputs include quoted prices for similar assets and liabilities in active markets, and inputs other than quoted prices that are observable for the asset or liability, such as interest rates and yield curves that are observable at commonly quoted intervals. Level 3 inputs are unobservable inputs for the asset or liability, and include situations where there is little, if any, market activity for the asset or liability. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, the level in the fair value hierarchy within which the fair value measurement in its entirety falls has been determined based on the lowest level input that is significant to the fair value measurement in its entirety. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the asset or liability. Transfers between levels of the fair values hierarchy are recognized at the actual date of the event or circumstance that caused the transfer.

(r)

Bank Owned Life Insurance

The Company purchased insurance on the lives of certain executives. The policies accumulate asset values to meet future liabilities including the payment of employee benefits such as the deferred compensation plan. Changes in the cash surrender value are recorded as other noninterest income in the consolidated statements of earnings.

(s)

Federal Home Loan Bank Borrowings

The Bank maintains a collateralized line of credit with the Federal Home Loan Bank (“FHLB”) of San Francisco. Under this line, the Bank may borrow on a short term or a long term (over one year) basis. FHLB advances are recorded and carried at their historical cost. FHLB advances are not transferable and may contain prepayment penalties. In addition to the collateral pledged, the Company is required to hold prescribed amounts of FHLB stock that vary with the usage of FHLB borrowings.

(t)

Comprehensive Income

Certain changes in assets and liabilities, such as unrealized gain and losses on available-for-sale securities are reported as a separate component of the equity section of the consolidated balance sheet, such items, along with net income, are components of comprehensive income.

(u)

Note Payable

The Company obtained a corporate loan with a five year term, for $6,000,000, payable at $50,000 principal monthly, plus interest, and is based on the 3-month LIBOR rate plus 4%.

(v)

Federal Home Loan Bank Stock

Federal Home Loan Bank (FHLB) stock represents an equity interest that does not have a readily determinable fair value because its ownership is restricted and it lacks a market (liquidity). FHLB stock is recorded at cost.

(w)

Reclassifications

Certain prior year information has been reclassified to conform to current year presentation. The reclassifications had no impact on consolidated net earnings or retained earnings.

(x)

Recent Accounting Pronouncements

In April 2013, the FASB issued ASU 2013-11, Income Taxes (Topic 740). This ASU requires an entity to present in the financial statements an unrecognized tax benefit as a liability and the unrecognized tax benefit should not be combined with deferred tax assets to the extent that a net operating loss carry-forward, tax loss or credit carry-forward is also not available at the reporting date.

The amendment is to be applied prospectively to all unrecognized tax benefits and is effective for annual and interim reporting periods beginning after December 15, 2013. The Company does not expect this ASU to have a material impact on the Company’s consolidated financial statements.

In January 2014, the FASB issued ASU No. 2014-04, Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon foreclosure. ASU 2014-04 clarifies that an in substance repossession or foreclosure occurs, and a creditor is considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan, upon either (1) the creditor obtaining legal title to the residential real estate property upon completion of a foreclosure or (2) the borrower conveying all interest in the residential real estate property to the creditor to satisfy that loan through completion of a deed in lieu of foreclosure or through a similar legal agreement. Additionally, the amendments require interim and annual disclosure of both (1) the amount of foreclosed residential real estate property held by the creditor and (2) the recorded investment in consumer mortgage loans collateralized by residential real estate property that are in the process of foreclosure according to local requirements of the applicable jurisdiction. The amendments are effective for annual and interim reports beginning on or after December 15, 2014 and can be applied with a modified retrospective transition method or prospectively. The adoption of ASU 2014-04 is not expected to have a material impact on the Company’s consolidated financial statements.

	At December 31, 2014, there were forty-eight securities in an unrealized loss position for greater than 12 consecutive months, and thirty-six securities in an unrealized loss position for under 12 months. At December 31, 2013, there were five securities in an unrealized loss position for greater than 12 consecutive months, and one hundred twelve securities in an unrealized loss position under 12 months. Management periodically evaluates each security in an unrealized loss position to determine if the impairment is temporary or other-than-temporary. Management has determined that no investment security is other-than-temporarily impaired at December 31, 2014 and 2013. The unrealized losses are due solely to interest rate changes, and the Company does not intend to sell nor expects it will be required to sell investment securities identified with impairments resulting from interest rate declines prior to the earliest of forecasted recovery or the maturity of the underlying investment security.

	The amortized cost and fair value of debt securities as of December 31, 2014, by contractual maturity, are shown below. Expected maturities may differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties.

	At December 31, 2014 and 2013, securities with an amortized cost of $77,808,000 and $70,678,000, and fair value of $78,617,000 and $70,640,000, respectively, were pledged as collateral for public deposits and for other purposes required by law.

As of December 31, 2014 and 2013, the Bank had investments in Federal Home Loan Bank stock classified as other equity security in the accompanying consolidated balance sheets of $4,258,000 and $3,988,000, respectively. As of December 31, 2014 and 2013, the Bank had investments in FRB of$1,260,000 and $1,062,000, respectively, also carried among other equity securities. These investments are carried at cost, and evaluated periodically for impairment. Federal Home Loan Bank and FRB stock can be redeemed at par by the government agencies. These securities cannot be sold to other investors. Management reviews the financial statements, credit rating and other pertinent financial information of these entities in order to determine if impairment has occurred. So long as there is sufficient evidence to support the ability of these entities to continue to redeem their stock, management believes these securities are not impaired.

Risk rating system

Loans to borrowers graded as pass or pooled loans represent loans to borrowers of acceptable or better credit quality. They demonstrate sound financial positions, repayment capacity and credit history. They have an identifiable and stable source of repayment.

Special mention loans have potential weaknesses that deserve management’s attention. If left uncorrected these potential weaknesses may result in a deterioration of the repayment prospects for the asset or in the Bank’s credit position at some future date. These assets are “not adversely classified” and do not expose the Bank to sufficient risk to warrant adverse classification.

Substandard loans are inadequately protected by current sound net worth, paying capacity of the borrower, or pledged collateral. Loans are normally classified as Substandard when there are unsatisfactory characteristics causing more than acceptable levels of risk. A substandard loan normally has one or more well-defined weakness that could jeopardize the repayment of the debt. For example, a) cash flow deficiency, which may jeopardize future payments; b) sale of non-collateral assets has become primary source of repayment; c) the borrower is bankrupt; or d) for any other reason, future repayment is dependent on court action.

Doubtful loans represent credits with weakness inherent in the Substandard classification and where collection or liquidation in full is highly questionable. To be classified Doubtful, there must be specific pending factors which prevent the Loan Review Officer from determining the amount of loss contained in the credit. When the amount of loss can be reasonably estimated, that amount is classified as “loss” and the remainder is classified as Substandard.

Real Estate – Multi-Family

Our multi-family commercial real estate loans are secured by multi-family properties located primarily in San Mateo and San Francisco Counties. These loans are made to investors where the primary source of loan repayment is from cash flows generated by the properties, through rent collections. The borrowers’ promissory notes are secured with recorded liens on the underlying properties. The borrowers would normally also be required to personally guarantee repayment of the loans. The Bank uses conservative underwriting standards in reviewing applications for credit. Generally, our borrowers have multiple sources of income, so if cash flow generated from the property declines, at least in the short term, the borrowers can normally cover these short term cash flow deficiencies from their available cash reserves. Risk of loss to the Bank is increased when there are cash flow decreases sufficiently large and for such a prolonged period of time that loan payments can no longer be made by the borrowers.

Commercial Real Estate Loans

Commercial Real Estate loans consist of loans secured by non-farm, non-residential properties, including, but not limited to industrial, hotel, assisted care, retail, office and mixed use buildings. Our commercial real estate loans are made primarily to investors or small businesses where our primary source of repayment is from cash flows generated by the properties, either through rent collection or business profits. The borrower’s promissory notes are secured with recorded liens on the underlying property. The borrowers would normally also be required to personally guarantee repayment of the loan. The Bank uses conservative underwriting standards in reviewing applications for credit. Generally, our borrowers have multiple sources of income, so if cash flow generated from the property declines, at least in the short term, the borrowers can normally cover these short term cash flow deficiencies from their available cash reserves. Risk of loss to the Bank is increased when there are cash flow decreases sufficiently large and for such a prolonged period of time that loan payments can no longer be made by the borrowers.

Real Estate Construction Loans

Our real estate construction loans are generally made to borrowers who are rehabilitating a building, converting a building use from one type of use to another, or developing land and building residential or commercial structures for sale or lease.

The borrower’s promissory notes are secured with recorded liens on the underlying property. The borrowers would normally also be required to personally guarantee repayment of the loan. The Bank uses conservative underwriting standards in reviewing applications for credit. Generally, our borrowers have sufficient resources to make the required construction loan payments during the construction and absorption or lease-up period.

After construction is complete, the loans are normally paid off from proceeds from the sale of the building or through a refinance to a commercial real estate loan. Risk of loss to the Bank is increased when there are material construction cost overruns, significant delays in the time to complete the project and/or there has been a material drop in the value of the projects in the marketplace since the inception of the loan.

Real Estate-1 to 4 family Loans

Our residential real estate loans are generally made to borrowers who are buying or refinancing their primary personal residence or a rental property of 1-4 single family residential units. The Bank uses conservative underwriting standards in reviewing applications for credit. Risk of loss to the Bank is increased when borrowers lose their primary source of income and/or property values decline significantly.

Commercial and Industrial Loans

Our commercial and industrial loans are generally made to small businesses to provide them with at least some of the working capital necessary to fund their daily business operations. These loans are generally either unsecured or secured by fixed assets, accounts receivable and/or inventory. The borrowers would normally also be required to personally guarantee repayment of the loan. The Bank uses conservative underwriting standards in reviewing applications for credit. Risk of loss to the Bank is increased when our small business customers experience a significant business downturn, incur significant financial losses, or file for relief from creditors through bankruptcy proceedings.

Consumer Loans

Our consumer and installment loans generally consist of personal loans, credit card loans, automobile loans or other loans secured by personal property. The Bank uses conservative underwriting standards in reviewing applications for credit. Risk of loss to the Bank is increased when borrowers lose their primary source of income, or file for relief from creditors through bankruptcy proceedings.

	Net deferred tax assets (included in other assets)	$	6,613		$	9,714			6,488

	As of December 31, 2014, management believes that it is more likely than not that the deferred tax assets will be realized through recovery of taxes previously paid and/or future taxable income. In assessing the Company’s ability to realize the tax benefits of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income, and tax planning strategies in making this assessment. Based upon the level of historical taxable income and projections for future taxable income over the periods which the deferred tax assets are deductible, management believes it is more likely than not that the Company will realize the recorded benefits of these deductible differences.

16_Financial_Instruments

16. Financial Instruments	Dec. 31, 2014
Financial Instruments Disclosure [Abstract]
Financial Instruments	The Bank is a party to financial instruments with off-balance-sheet risk in the normal course of business. These financial instruments include commitments to extend credit in the form of loans or through standby letters of credit. These instruments involve, to varying degrees, elements of credit and interest-rate risk in excess of the amount recognized in the balance sheet. The Bank’s exposure to credit loss is represented by the contractual amount of those instruments and is usually limited to amounts funded or drawn. The contract or notional amounts of these agreements, which are not included in the balance sheets, are an indicator of the Bank’s credit exposure.

	Commitments to extend credit generally carry variable interest rates and are subject to the same credit standards used in the lending process for on-balance-sheet instruments. Additionally, the Bank periodically reassesses the customer’s creditworthiness through ongoing credit reviews. The Bank generally requires collateral or other security to support commitments to extend credit. The following table provides summary information on financial instruments whose contract amounts represent credit risk as of December 31:

		31-Dec
	(Dollars amounts in thousands)	2014		2013
	Financial instruments whose contract amounts represent credit risk:

	Lines of credit	$	70,472	$	65,120
	Other Commercial Commitments:
	Undisbursed loan commitments		59,592		52,398
	Mastercard/Visa lines		6,444		5,992
	Standby Letters of credit		5,713		6,199
		$	142,221	$	129,709

	Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The Bank evaluates each customer’s creditworthiness on a case-by-case basis, following normal lending policies. The amount of collateral obtained, if deemed necessary by the Bank upon extension of credit, is based on management’s credit evaluation. Collateral held varies, but may include accounts receivable, inventory, property, plant and equipment, and income-producing commercial and residential properties. Equity reserves and unused credit card lines are additional commitments to extend credit. Many of these customers are not expected to draw down their total lines of credit, and therefore, the total contract amount of these lines does not necessarily represent future cash requirements. Standby letters of credit are conditional commitments issued by the Bank to guarantee the performance of a customer 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 customers.

	The Bank issues both financial and performance standby letters of credit. The financial standby letters of credit are primarily to guarantee payment to third parties. As of December 31, 2014, there were financial standby letters of credit of $4,833,000 issued. The performance standby letters of credit are typically issued to municipalities as specific performance bonds.

	As of December 31, 2014 there were performance letters of credit of $880,000 issued. The terms of the guarantees will expire in 2015. The Bank has experienced no draws on these letters of credit, and does not expect to in the future. However, should a triggering event occur, the Bank either has collateral in excess of the letters of credit or embedded agreements of recourse from the customer.

	The following methods and assumptions were used by the Company in estimating the fair value disclosures for financial instruments that are not carried at fair value on either a recurring or non-recurring basis:

Cash and Cash Equivalents including Interest Bearing Time Deposits with Financial Institutions.

The carrying amounts reported in the balance sheet for cash and short-term instruments are a reasonable estimate of fair value, which will approximate their historical cost.

Securities Available-for-Sale.

Fair values for investment securities are based on quoted market prices, where available. If quoted market prices are not available, fair values are based on quoted market prices of comparable instruments.

Loans Receivable.

For variable-rate loans that reprice frequently and with no significant change in credit risk, fair values are based on carrying values. For fixed rate loans, fair values are based on discounted cash flows, credit risk factors, and liquidity factors.

Other equity securities.

These are mostly Federal Reserve Bank stock and Federal Home Loan Bank stock, carried in other assets on the consolidated balance sheet. These securities can only be issued and redeemed at par by the issuing entities. They cannot be sold in in open market transactions. Fair value is estimated to be carrying value.

Deposit liabilities.

The fair values disclosed for demand deposits (e.g., interest and non-interest checking, savings, and money market accounts) are, by definition, equal to the amount payable on demand at reporting date (i.e., their carrying amounts). The fair values for fixed-rate certificates of deposit are based on discounted cash flows.

Federal Home Loan Bank Advances.

The fair values of Federal Home Loan Bank Advances are based on discounted cash flows. The discount rate is equal to the market currently offered on similar products.

Note payable.

Fair value is equal to the current balance. They represent a corporate loan with a monthly variable rate, based on the 3-month LIBOR rate plus 4%.

Accrued Interest Receivable and Payable.

The interest receivable and payable balances approximate their fair value due to the short-term nature of their settlement dates.

Undisbursed loan commitments, lines of credit, Mastercard line and standby letters of credit.

The fair value of these off-balance sheet items are based on discounted cash flows of expected fundings.

The Company has excluded non-financial assets and non-financial liabilities defined by the Codification (ASC 820-10-15-A), such as Company premises and equipment, deferred taxes and other liabilities. In addition, the Company has not disclosed the fair value of financial instruments specifically excluded from disclosure requirements of the Financial Instruments Topic of the Codification (ASC 825-10-50-8), such as Bank-owned life insurance policies.

The following table provides summary information on the estimated fair value of financial instruments at December 31, 2014 and 2013:

18. Significant Group Concentrations of Credit Risk	Dec. 31, 2014
Concentration Risk Disclosure [Abstract]
Significant Group Concentrations of Credit Risk	Most of the Bank’s business activity is with customers located within San Mateo and San Francisco counties. Generally, loans are secured by assets of the borrowers. Loans are expected to be repaid from cash flows or proceeds from the sale of selected assets of the borrowers. The Bank does not have significant concentrations of loans to any one industry, but does have loan concentrations in commercial real estate loans that are considered high by regulatory standards. The Bank has mitigated this concentration to a large extent by utilizing underwriting standards that are more conservative than regulatory guidelines, and performing stress testing on this segment of the portfolio to insure that the commercial real estate loan portfolio will perform within management expectations given an additional downturn in commercial lease rates and commercial real estate valuations. The distribution of commitments to extend credit approximates the distribution of loans outstanding. Commercial and standby letters of credit were granted primarily to commercial borrowers. The contractual amounts of credit-related financial instruments such as commitments to extend credit, credit-card arrangements, and letters of credit represent the amounts of potential accounting loss should the contract be fully drawn upon, the customer default, and the value of any existing collateral become worthless.

Regulatory Matters Disclosure [Abstract]
Regulatory matters	The Company, as a bank holding company, is subject to regulation by the Board of Governors of the Federal Reserve System under the Bank Holding Company Act of 1956, as amended. The Bank is subject to various regulatory capital requirements administered by the 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 Company’s financial statements.

	Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and the Bank must meet specific capital guidelines that involve quantitative measures of the Company’s and the Bank’s assets, liabilities and certain off balance-sheet items as calculated under regulatory accounting practices.

	The capital amounts and classification are also subject to qualitative judgments by the regulators about asset groupings, 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 (set forth in the table below) of total and Tier 1 capital (as defined in the regulations) to risk-weighted assets (as defined), and of Tier 1 capital (as defined) to average assets (as defined). Management believes, as of December 31, 2014, that the Company and the Bank have met all regulatory capital requirements.

	As of December 31, 2014, the most recent notification from the regulatory agencies categorized the Bank as well capitalized under the regulatory framework for prompt corrective action. 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 table. There are no conditions or events since that notification that management believes have changed the Bank’s categories.

	The consolidated actual capital amounts and ratios of the Company and the Bank are also presented in the following table:

	The Federal Reserve and the Federal Deposit Insurance Corporation approved final capital rules in July 2013, that substantially amend the existing capital rules for banks. These new rules reflect, in part, certain standards initially adopted by the Basel Committee on Banking Supervision in December 2010 (which standards are commonly referred to as “Basel III”) as well as requirements contemplated by the Dodd-Frank Act.
	Under the new capital rules, the Bank will be required to meet certain minimum capital requirements that differ from current capital requirements. The rules implement a new capital ratio of common equity Tier 1 capital to risk- weighted assets. Common equity Tier 1 capital generally consists of retained earnings and common stock (subject to certain adjustments) as well as accumulated other comprehensive income (“AOCI”), except to the extent that the Bank exercises a one-time irrevocable option to exclude certain components of AOCI as of March 31, 2015. The Bank will also be required to establish a “conservation buffer,” consisting of a common equity Tier 1 capital amount equal to 2.5% of risk-weighted assets to be phased in by 2019. An institution that does not meet the conservation buffer will be subject to restrictions on certain activities including payment of dividends, stock repurchases, and discretionary bonuses to executive officers.
	The prompt corrective action rules are modified to include the common equity Tier 1 capital ratio and to increase the Tier 1 capital ratio requirements for the various thresholds. For example, the requirements for the Bank to be considered well-capitalized under the rules will be a 5.0% leverage ratio, a 6.5% common equity Tier l capital ratio, an 8.0% Tier 1 capital ratio, and a 10.0% total capital ratio. To be adequately capitalized, those ratios are 4.0%, 4.5%, 6.0%, and 8.0%, respectively.
	The rules modify the manner in which certain capital elements are determined. The rules make changes to the methods of calculating the risk-weighting of certain assets, which in turn affects the calculation of the risk-weighted capital ratios. Higher risk weights are assigned to various categories of assets, including commercial real estate loans, credit facilities that finance the acquisition, development or construction of real property, certain exposures or credit that are 90 days past due or are nonaccrual, securitization exposures, and in certain cases mortgage servicing rights and deferred tax assets.

	The Bank is required to comply with the new capital rules on January 1, 2015, with a measurement date of March 31,2015. The conservation buffer will be phased-in beginning in 2016, and will take full effect on January 1,2019. Certain calculations under the rules will also have phase-in periods.

20. Stock Option Plans	Dec. 31, 2014
Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock Option Plans	In 1997, the Board of Directors of the Bank adopted the First National Bank of Northern California 1997 stock option plan. Pursuant to the holding company reorganization effective March 15, 2002, the Bank stock option plan became the FNB Bancorp stock option Plan. In 2002, the Company adopted an incentive employee stock option plan known as the 2002 FNB Bancorp plan. In 2008, the Company adopted an incentive employee stock option plan known as the 2008 FNB Bancorp stock option plan. The plans allow the Company as of December 31, 2014 to grant options to employees covering 96,397 shares.

	Incentive stock options currently outstanding become exercisable in one to five years from the grant date, based on a vesting schedule of 20% per year and expire 10 years after the grant date. Nonqualified options to directors become vested on the date of grant. The options exercise price is the fair value of the per share price of the underlying stock options at the grant date.

	The amount of compensation expense for options recorded in the years ended December 31, 2014, 2013, and 2012 was $307,000, $328,000, and $210,000, respectively. There was an income tax benefit related to stock option exercises for the years ended December 31, 2014, 2013 and 2012 of $483,000, $354,000 and $30,000.

	The amount of total unrecognized compensation expense related to non-vested options at December 31, 2014 was $743,000, and the weighted average period it will be amortized over is 3.6 years. The assumptions for options granted in 2014 were as follows: dividend yield of 1.49% for the year; risk-free interest rate of 2.08%; expected volatility of 41.85%; expected life of 9.1 years. This resulted in a weighted average fair value of $4.08. The assumptions for options granted in 2013 were as follows: dividend yield of 1.35% for the year; risk-free interest rate of 2.55%; expected volatility of 24.71%; expected life of 9.3 years; $4.08 and $7.81 per share for 2014 and 2013 grants, respectively. There were no options granted in 2012.

	A summary of option activity, adjusted for stock dividends, issued under the 2008 FNB Bancorp Plan as of December 31, 2014 and changes during the year then ended is presented below.
