SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

A summary of the significant accounting and reporting policies applied in the presentation of the accompanying financial statements follows:

Nature of Operations and Basis of Presentation

Middlefield Banc Corp. (the “Company”) is an Ohio corporation organized to become the holding company of The Middlefield Banking Company (“MBC”). MBC is a state-chartered bank located in Ohio. On April 19, 2007, Middlefield Banc Corp. acquired Emerald Bank (“EB”), an Ohio-chartered commercial bank headquartered in Dublin, Ohio. On October 23, 2009, the Company established an asset resolution subsidiary named EMORECO, Inc. The Company and its subsidiaries derive substantially all of their income from banking and bank-related services, which includes interest earnings on residential real estate, commercial mortgage, commercial and consumer financings as well as interest earnings on investment securities and deposit services to its customers through ten locations. The Company is supervised by the Board of Governors of the Federal Reserve System, while MBC and EB are subject to regulation and supervision by the Federal Deposit Insurance Corporation and the Ohio Division of Financial Institutions. EB merged into MBC on January 20, 2014.

The consolidated financial statements of the Company include its wholly-owned subsidiaries, MBC, EB, and EMORECO, Inc. (the “Banks”). Significant intercompany items have been eliminated in preparing the consolidated financial statements.

The financial statements have been prepared in conformity with U.S. generally accepted accounting principles. In preparing the financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the balance sheet date and revenues and expenses for the period. Actual results could differ from those estimates.

Investment Securities

Investment securities are classified at the time of purchase, based on management’s intention and ability, as securities held to maturity or securities available for sale. Debt securities acquired with the intent and ability to hold to maturity are stated at cost adjusted for amortization of premium and accretion of discount, which are computed using a level yield method and recognized as adjustments of interest income. Certain other debt securities have been classified as available for sale to serve principally as a source of liquidity. Unrealized holding gains and losses for available-for-sale securities are reported as a separate component of stockholders’ equity, net of tax, until realized. Realized security gains and losses are computed using the specific identification method. Interest and dividends on investment securities are recognized as income when earned.

Common stock of the Federal Home Loan Bank (“FHLB”) represents ownership in an institution that is wholly owned by other financial institutions. This equity security is accounted for at cost and classified with other assets. The FHLB of Cincinnati has reported profits for 2013 and 2012, remains in compliance with regulatory capital and liquidity requirements, and continues to pay dividends on the stock and make redemptions at the par value. With consideration given to these factors, management concluded that the stock was not impaired at December 31, 2013 or 2012.

Securities are evaluated on at least a quarterly basis and more frequently when economic or market conditions warrant such an evaluation to determine whether a decline in their value is other than temporary. For debt securities, management considers whether the present value of cash flows expected to be collected are less than the security’s amortized cost basis (the difference defined as the credit loss), the magnitude and duration of the decline, the reasons underlying the decline and the Company’s intent to sell the security or whether it is more likely than not that the Company would be required to sell the security before its anticipated recovery in market value, to determine whether the loss in value is other than temporary. Once a decline in value is determined to be other than temporary, if the Company does not intend to sell the security, and it is more likely than not that it will not be required to sell the security, before recovery of the security’s amortized cost basis, the charge to earnings is limited to the amount of credit loss. Any remaining difference between fair value and amortized cost (the difference defined as the non-credit portion) is recognized in other comprehensive income, net of applicable taxes. Otherwise, the entire difference between fair value and amortized cost is charged to earnings. For equity securities where the fair value has been significantly below cost for one year, the Company’s policy is to recognize an impairment loss unless sufficient evidence is available that the decline is not other than temporary and a recovery period can be predicted.

Loans

Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff generally are reported at their outstanding unpaid principal balances net of the allowance for loan and lease loss. Interest income is recognized as income when earned on the accrual method. The accrual of interest is discontinued on a loan when management believes, after considering economic and business conditions, the borrower’s financial condition is such that collection of interest is doubtful. Interest received on nonaccrual loans is recorded as income or applied against principal according to management’s judgment as to the collectability of such principal.

Loan origination fees and certain direct loan origination costs are being deferred and the net amount amortized as an adjustment of the related loan’s yield. Management is amortizing these amounts over the contractual life of the related loans.

Allowance for Loan and Lease Loss

The allowance for loan and lease loss represents the amount which management estimates is adequate to provide for probable loan losses inherent in the loan portfolio. The allowance method is used in providing for loan losses. Accordingly, all loan losses are charged to the allowance, and all recoveries are credited to it. The allowance for loan and lease loss is established through a provision for loan losses which is charged to operations. The provision is based on management’s periodic evaluation of the adequacy of the allowance for loan and lease loss, which encompasses the overall risk characteristics of the various portfolio segments, past experience with losses, the impact of economic conditions on borrowers, and other relevant factors. The estimates used in determining the adequacy of the allowance for loan and lease loss, including the amounts and timing of future cash flows expected on impaired loans, are particularly susceptible to significant change in the near term.

A loan is considered impaired when it is probable the borrower will not repay the loan according to the original contractual terms of the loan agreement. Management has determined that first mortgage loans on one-to-four family properties and all consumer loans represent large groups of smaller-balance homogeneous loans that are to be collectively evaluated. Loans that experience insignificant payment delays, which are defined as 90 days or less, generally are not classified as impaired. A loan is not impaired during a period of delay in payment if the Company expects to collect all amounts due, including interest accrued, at the contractual interest rate for the period of delay. All loans identified as impaired are evaluated independently by management. The Company estimates credit losses on impaired loans based on the present value of expected cash flows or the fair value of the underlying collateral if the loan repayment is expected to come from the sale or operation of such collateral. Impaired loans, or portions thereof, are charged off when it is determined a realized loss has occurred. Until such time, an allowance for loan and lease loss is maintained for estimated losses. Cash receipts on impaired loans are applied first to accrued interest receivable unless otherwise required by the loan terms, except when an impaired loan is also a nonaccrual loan, in which case the portion of the payment related to interest is recognized as income.

Mortgage loans secured by one-to-four family properties and all consumer loans are large groups of smaller-balance homogeneous loans and are measured for impairment collectively. Management determines the significance of payment delays on a case-by-case basis, taking into consideration all circumstances concerning the loan, the creditworthiness and payment history of the borrower, the length of the payment delay, and the amount of shortfall in relation to the principal and interest owed.

Premises and Equipment

Land is carried at cost. Premises and equipment are stated at cost net of accumulated depreciation. Depreciation is computed on the straight-line method over the estimated useful lives of the assets, which range from 3 to 20 years for furniture, fixtures, and equipment and 3 to 40 years for buildings and leasehold improvements. Expenditures for maintenance and repairs are charged against income as incurred. Costs of major additions and improvements are capitalized.

Goodwill

The Company accounts for goodwill using a two-step process for testing the impairment of goodwill on at least an annual basis. This approach could cause more volatility in the Company’s reported net income because impairment losses, if any, could occur irregularly and in varying amounts. No impairment of goodwill was recognized in any of the periods presented.

Intangible Assets

Intangible assets include core deposit intangibles, which are a measure of the value of consumer demand and savings deposits acquired in business combinations accounted for as purchases. The core deposit intangibles are being amortized to expense over a 10 year life on a straight-line basis. The recoverability of the carrying value of intangible assets is evaluated on an ongoing basis, and permanent declines in value, if any, are charged to expense.

Bank-Owned Life Insurance (“BOLI”)

The Company owns insurance on the lives of a certain group of key employees. The policies were purchased to help offset the increase in the costs of various fringe benefit plans including healthcare. The cash surrender value of these policies is included as an asset on the Consolidated Balance Sheet and any increases in the cash surrender value are recorded as noninterest income on the Consolidated Statement of Income. In the event of the death of an insured individual under these policies, the Company would receive a death benefit, which would be recorded as noninterest income.

Other Real Estate Owned

Real estate properties acquired through foreclosure are initially recorded at fair value at the date of foreclosure, establishing a new cost basis. After foreclosure, management periodically performs valuations and the real estate is carried at the lower of cost or fair value less estimated cost to sell. Revenue and expenses from operations of the properties, gains or losses on sales and additions to the valuation allowance are included in operating results.

Income Taxes

The Company and its subsidiaries file a consolidated federal income tax return. 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. As changes in tax laws or rates are enacted, deferred tax assets and liabilities are adjusted through the provision for income taxes.

Earnings Per Share

The Company provides dual presentation of basic and diluted earnings per share. Basic earnings per share are calculated utilizing net income as reported in the numerator and average shares outstanding in the denominator. The computation of diluted earnings per share differs in that the dilutive effects of any stock options, warrants, and convertible securities are adjusted in the denominator.

Stock-Based Compensation

The Company accounts for stock compensation based on the grant date fair value of all share-based payment awards that are expected to vest, including employee share options to be recognized as employee compensation expense over the requisite service period.

For purposes of computing results, the Company estimated the fair values of stock options using the Black-Scholes option-pricing model. The model requires the use of subjective assumptions that can materially affect fair value estimates. The fair value of each option is amortized into compensation expense on a straight-line basis between the grant date for the option and each vesting date. The fair value of each stock option granted was estimated using the following weighted-average assumptions:

Grant

Expected

Risk-Free

Year

Dividend

Interest Rate

Volatility

Life (in years)

9.96

During the years ended December 31, 2013, 2012, and 2011, the Company recorded $0, $0, and $16,000, of compensation cost related to vested stock options. As of December 31, 2013, there was no unrecognized compensation cost related to unvested stock options. The weighted-average fair value of the stock option granted for 2011 was $1.75.

The Company also issued 1,722 and 2,400 shares of restricted stock and recorded stock–based compensation expense of $32,000 and $43,000 in 2012 and 2011, respectively. There were no shares of restricted stock issued in 2013.

For the year ended December 31, 2013, 21,112 options were exercised resulting in net proceeds of $77,000.

Cash Flow Information

The Company has defined cash and cash equivalents as those amounts included in the Consolidated Balance Sheet captions as “Cash and due from banks” and “Federal funds sold” with original maturities of less than 90 days.

Advertising Costs

Advertising costs are expensed as incurred. Advertising expenses amounted to $445,000, $423,000, and $439,000, for 2013, 2012, and 2011, respectively.

Reclassification of Comparative Amounts

Certain comparative amounts for prior years have been reclassified to conform to current-year presentations. Such reclassifications did not affect net income or retained earnings.

Recent Accounting Pronouncements

In February 2013, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2013-02, Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income. The standard requires that companies present either in a single note or parenthetically on the face of the financial statements, the effect of significant amounts reclassified from each component of accumulated other comprehensive income based on its source and the income statement line items affected by the reclassification. The new requirements will take effect for public companies in fiscal years, and interim periods within those years, beginning after December 15, 2012. The Company adopted this standard on January 1, 2013. The effect of adopting this standard increased our disclosure surrounding reclassification items out of accumulated other comprehensive income.

In February 2013, the FASB issued ASU 2013-04, Obligations Resulting from Joint and Several Liability Arrangements for Which the Total Amount of the Obligation is Fixed at the Reporting Date. The ASU requires the measurement of obligations resulting from joint and several liability arrangements for which the total amount of the obligation is fixed at the reporting date as the sum of the amount the reporting entity agreed to pay on the basis of its arrangement with its co-obligors as well as any additional amount that the entity expects to pay on behalf of its co-obligors. The new standard is effective retrospectively for fiscal years and interim periods within those years, beginning after December 15, 2013, and early adoption is permitted. This ASU is not expected to have a significant impact on the Company’s financial statements.

In July 2013, the FASB issued ASU 2013-11, Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists. This Update applies to all entities that have unrecognized tax benefits when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists at the reporting date. An unrecognized tax benefit, or a portion of an unrecognized tax benefit, should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward, except as follows. To the extent a net operating loss carryforward, a similar tax loss, or a tax credit carryforward is not available at the reporting date under the tax law of the applicable jurisdiction to settle any additional income taxes that would result from the disallowance of a tax position or the tax law of the applicable jurisdiction does not require the entity to use, and the entity does not intend to use, the deferred tax asset for such purpose, the unrecognized tax benefit should be presented in the financial statements as a liability and should not be combined with deferred tax assets. The assessment of whether a deferred tax asset is available is based on the unrecognized tax benefit and deferred tax asset that exist at the reporting date and should be made presuming disallowance of the tax position at the reporting date. The amendments in this Update are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. For nonpublic entities, the amendments are effective for fiscal years, and interim periods within those years, beginning after December 15, 2014. Early adoption is permitted. The amendments should be applied prospectively to all unrecognized tax benefits that exist at the effective date. Retrospective application is permitted.

In January 2014, FASB issued ASU 2014-01, Investments – Equity Method and Join Ventures (Topic 323): Accounting for Investments in Qualified Affordable Housing Projects. The amendments in this Update permit reporting entities to make an accounting policy election to account for their investments in qualified affordable housing projects using the proportional amortization method if certain conditions are met. Under the proportional amortization method, an entity amortizes the initial cost of the investment in proportion to the tax credits and other tax benefits received and recognizes the net investment performance in the income statement as a component of income tax expense (benefit). The amendments in this Update should be applied retrospectively to all periods presented. A reporting entity that uses the effective yield method to account for its investments in qualified affordable housing projects before the date of adoption may continue to apply the effective yield method for those preexisting investments. The amendments in this Update are effective for public business entities for annual periods and interim reporting periods within those annual periods, beginning after December 15, 2014. Early adoption is permitted. This ASU is not expected to have a significant impact on the Company’s financial statements.

In January 2014, the FASB issued ASU 2014-04, Receivables – Troubled Debt Restructurings by Creditors (Subtopic 310-40): Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure. The amendments in this Update clarify 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 in this Update are effective for public business entities for annual periods, and interim periods within those annual periods, beginning after December 15, 2014. An entity can elect to adopt the amendments in this Update using either a modified retrospective transition method or a prospective transition method. This ASU is not expected to have a significant impact on the Company’s financial statement.

There were 98 securities that were considered temporarily impaired at December 31, 2013.
On a quarterly basis, the Company performs an assessment to determine whether there have been any events or economic circumstances indicating that a security with an unrealized loss has suffered other-than-temporary impairment (“OTTI”). A debt security is considered impaired if the fair value is less than its amortized cost basis at the reporting date. The accounting literature requires the Company to assess whether the unrealized loss is other-than-temporary. For equity securities where the fair value has been significantly below cost for one year, the Company’s policy is to recognize an impairment loss unless sufficient evidence is available that the decline is not other than temporary and a recovery period can be predicted.
The Company has asserted that at December 31, 2013 and 2012, the declines outlined in the above table represent temporary declines and the Company does not intend to sell and does not believe it will be required to sell these securities before recovery of their cost basis, which may be at maturity. The Company has concluded that any impairment of its investment securities portfolio outlined in the above table is not other than temporary and is the result of interest rate changes, sector credit rating changes, or company-specific rating changes that are not expected to result in the noncollection of principal and interest during the period.
Debt securities issued by U.S. government agencies, U.S. government-sponsored enterprises, and state and political subdivisions accounted for more than 97.2% of the total available-for-sale portfolio as of December 31, 2013, and no credit losses are expected, given the explicit and implicit guarantees provided by the U.S. federal government and the lack of significant unrealized loss positions within the obligations of state and political subdivisions security portfolio. The Company’s assessment was concentrated mainly on private-label collateralized mortgage obligations of approximately $3.4 million, for which the Company evaluates credit losses on a quarterly basis. Gross unrealized gains related to private-label collateralized mortgage obligations amounted to $327,000, with no associated gross unrealized loss. The Company considered the following factors in determining whether a credit loss exists and the period over which the debt security is expected to recover:
	●	The length of time and the extent to which the fair value has been less than the amortized cost basis.
	●	Changes in the near term prospects of the underlying collateral of a security such as changes in default rates, loss severity given default and significant changes in prepayment assumptions.
	●	The level of cash flows generated from the underlying collateral supporting the principal and interest payments of the debt securities.
	●	Any adverse change to the credit conditions and liquidity of the issuer, taking into consideration the latest information available about the overall financial condition of the issuer, credit ratings, recent legislation, and government actions affecting the issuer’s industry and actions taken by the issuer to deal with the present economic climate.
The Company determined equity securities in financial institutions to be other than temporarily impaired and recognized a loss of $194,000 in 2011. This amount represents a before-tax, non-cash charge, and was recorded as a reduction to noninterest income.
The Company’s investment in one private-label collateralized mortgage obligation with a carrying value of $899,000 was impaired in 2011 as a result of the Company’s determination that declines in their fair value were other than temporary. As a result of this determination, the Company recognized a $35,000 before-tax, non-cash charge, which was recorded as a reduction to noninterest income.

The Company also serves the central Ohio market with offices in Dublin and Westerville, Ohio. Commercial, residential, consumer, and agricultural loans are granted. Although the Company has a diversified loan portfolio at December 31, 2013 and 2012, loans outstanding to individuals and businesses are dependent upon the local economic conditions in its immediate trade area.
	The following table summarizes the primary segments of the loan portfolio and the allowance for loan and lease loss as of December 31, 2013 and 2012 (in thousands):

	The Company’s loan portfolio is segmented to a level that allows management to monitor risk and performance. The portfolio is segmented into Commercial and Industrial (“C&I”), Real Estate Construction, Real Estate - Mortgage which is further segmented into Residential and Commercial real estate, and Consumer Installment Loans. The C&I loan segment consists of loans made for the purpose of financing the activities of commercial customers. The residential mortgage loan segment consists of loans made for the purpose of financing the activities of residential homeowners. The commercial mortgage loan segment consists of loans made for the purpose of financing the activities of commercial real estate owners and operators. The consumer loan segment consists primarily of installment loans and overdraft lines of credit connected with customer deposit accounts.
	Management evaluates individual loans in all of the commercial segments for possible impairment if the loan is greater than $150,000 and if the loan either is in nonaccrual status, or is risk rated Special Mention or Substandard and is greater than 90 days past due. Loans are considered to be impaired when, 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. Factors considered by management in evaluating impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. The Company does not separately evaluate individual consumer and residential mortgage loans for impairment, unless such loans are part of a larger relationship that is impaired.
	Once the determination has been made that a loan is impaired, the determination of whether a specific allocation of the allowance is necessary is measured by comparing the recorded investment in the loan to the fair value of the loan using one of three methods: (a) the present value of expected future cash flows discounted at the loan’s effective interest rate; (b) the loan’s observable market price; or (c) the fair value of the collateral less selling costs. The method is selected on a loan-by-loan basis, with management primarily utilizing the fair value of collateral method. The evaluation of the need and amount of a specific allocation of the allowance and whether a loan can be removed from impairment status is made on a quarterly basis. The Company’s policy for recognizing interest income on impaired loans does not differ from its overall policy for interest recognition.
	The following tables present impaired loans by class, segregated by those for which a specific allowance was required and those for which a specific allowance was not necessary (in thousands):

The Company does not forgive principal upon troubled debt restructuring. Therefore, the post-modification outstanding recorded investment equals pre-modification outstanding recorded investment for each timeframe and category.
Management uses a nine-point internal risk-rating system to monitor the credit quality of the overall loan portfolio. The first five categories are considered not criticized and are aggregated as Pass-rated. The criticized rating categories utilized by management generally follow bank regulatory definitions. The Special Mention category includes assets that are currently protected but are potentially weak, resulting in an undue and unwarranted credit risk, but not to the point of justifying a Substandard classification.  Loans in the Substandard category have well-defined weaknesses that jeopardize the liquidation of the debt and have a distinct possibility that some loss will be sustained if the weaknesses are not corrected.  All loans greater than 90 days past due are considered Substandard.  Any portion of a loan that has been charged off is placed in the Loss category.
To help ensure that risk ratings are accurate and reflect the present and future capacity of borrowers to repay a loan as agreed, the Company has a structured loan-rating process with several layers of internal and external oversight.  Generally, consumer and residential mortgage loans are included in the Pass categories unless a specific action, such as bankruptcy, repossession, or death, occurs to raise awareness of a possible credit event.  The Company’s Commercial Loan Officers are responsible for the timely and accurate risk rating of the loans in their portfolios at origination and on an ongoing basis.  The Credit Department performs an annual review of all commercial relationships $200,000 or greater.  Confirmation of the appropriate risk grade is included in the review on an ongoing basis.  The Company has an experienced Loan Review Department that continually reviews and assesses loans within the portfolio.  The Company engages an external consultant to conduct loan reviews on a semiannual basis. Generally, the external consultant reviews commercial relationships greater than $250,000 and/or criticized relationships greater than $125,000.  Detailed reviews, including plans for resolution, are performed on loans classified as Substandard on a quarterly basis.  Loans in the Special Mention and Substandard categories that are collectively evaluated for impairment are given separate consideration in the determination of the allowance.
The following tables present the classes of the loan portfolio summarized by the aggregate Pass rating and the criticized categories of Special Mention, Substandard, and Doubtful within the internal risk rating system as of December 31, 2013 and 2012 (in thousands):

Interest income that would have been recorded had these loans not been placed on nonaccrual status was $439,000 in 2013; $756,000 in 2012; and $859,000 in 2011.
An allowance for loan and lease loss (“ALLL”) is maintained to absorb losses from the loan portfolio.  The ALLL is based on management’s continuing evaluation of the risk characteristics and credit quality of the loan portfolio, assessment of current economic conditions, diversification and size of the portfolio, adequacy of collateral, past and anticipated loss experience, and the amount of nonperforming loans.
The Company’s methodology for determining the ALLL is based on the requirements of ASC Section 310-10-35 for loans individually evaluated for impairment (discussed above) and ASC Subtopic 450-20 for loans collectively evaluated for impairment, as well as the Interagency Policy Statement on the Allowance for Loan and Lease Losses and other bank regulatory guidance.   The total of the two components represents the Company’s ALLL.
Loans that are collectively evaluated for impairment are analyzed, with general allowances being made as appropriate.  For general allowances, historical loss trends are used in the estimation of losses in the current portfolio.  These historical loss amounts are modified by other qualitative factors.
The classes described above, which are based on the purpose code assigned to each loan, provide the starting point for the ALLL analysis.  Management tracks the historical net charge-off activity at the purpose code level.  A historical charge-off factor is calculated utilizing the last four consecutive quarters.
Management has identified a number of additional qualitative factors which it uses to supplement the historical charge-off factor, because these factors are likely to cause estimated credit losses associated with the existing loan pools to differ from historical loss experience.  The additional factors that are evaluated quarterly and updated using information obtained from internal, regulatory, and governmental sources are: national and local economic trends and conditions; levels of and trends in delinquency rates and nonaccrual loans; trends in volumes and terms of loans; effects of changes in lending policies; experience, ability, and depth of lending staff; value of underlying collateral; and concentrations of credit from a loan type, industry, and/or geographic standpoint.
Management reviews the loan portfolio on a quarterly basis using a defined, consistently applied process in order to make appropriate and timely adjustments to the ALLL.  When information confirms all or part of specific loans to be uncollectible, these amounts are promptly charged off against the ALLL.
The following tables summarize the primary segments of the loan portfolio (in thousands):

The C&I ALLL balance declined from $1.7 million at December 31, 2012 to $614,000 at December 31, 2013. Loan grade reclassifications resulted in a shift of $660,000 of specific reserve from this category. Residential mortgage real estate ALLL increased from $2.9 million to $3.7 million during the year ended December 31, 2013. This was largely the result of increasing the 1-4 family owner-occupied historical loss ratio. The real estate construction ALLL balance declined from $1.1 million at December 31, 2012 to $576,000 at December 31, 2013. The credit provision in this category was related to a fourth quarter shift of one loan from the classified list. At the time of removal, this loan had a balance of $3.1 million and the associated reserve was $700,000. A provision in any loan portfolio is not necessarily related to current charge-offs, but is a result of the evaluation of the loans in that category.

	The Company entered into a ten-year “Convertible Select” fixed commitment advance arrangement with the FHLB. Rates may be reset at the FHLB’s discretion on a quarterly basis based on the three-month LIBOR rate. At each rate change, the Company may exercise a put option and satisfy the obligation without penalty.
	Fixed-rate amortizing advances from the FHLB require monthly principal and interest payments and an annual 20 percent paydown of outstanding principal. Monthly principal and interest payments are adjusted after each 20 percent paydown. Under the terms of a blanket agreement, FHLB borrowings are secured by certain qualifying assets of the Company which consist principally of first mortgage loans or mortgage-backed securities. Under this credit arrangement, the Company has a remaining borrowing capacity of approximately $85.3 million at December 31, 2013.
	The Company formed a special purpose entity (“Entity”) to issue $8,000,000 of floating rate, obligated mandatorily redeemable securities, and $248,000 in common securities as part of a pooled offering. The rate adjusts quarterly, equal to LIBOR plus 1.67%. The Entity may redeem them, in whole or in part, at face value. The Company borrowed the proceeds of the issuance from the Entity in December 2006 in the form of an $8,248,000 note payable, which is included in the other borrowings on the Company’s Consolidated Balance Sheet.

	No valuation allowance was established at December 31, 2013 and 2012, in view of the Company’s ability to carry-back to taxes paid in previous years and certain tax strategies, coupled with the anticipated future taxable income as evidenced by the Company's earnings potential.

	Benefits from tax positions should be recognized in the financial statements only when it is more likely than not that the tax position will be sustained upon examination by the appropriate taxing authority that would have full knowledge of all relevant information. A tax position that meets the more-likely-than-not recognition threshold is measured at the largest amount of benefit that is greater than 50 percent likely of being realized upon ultimate settlement. Tax positions that previously failed to meet the more-likely-than-not recognition threshold should be recognized in the first subsequent financial reporting period in which that threshold is met. Previously recognized tax positions that no longer meet the more-likely-than-not recognition threshold should be derecognized in the first subsequent financial reporting period in which that threshold is no longer met.
	At December 31, 2013 and December 31, 2012, the Company had no unrecognized tax benefits. The Company does not expect the total amount of unrecognized tax benefits to significantly increase within the next 12 months. The Company recognizes interest and penalties on unrecognized tax benefits as a component of income tax expense.
	The Company and the Bank are subject to U.S. federal income tax as well as an income tax in the state of Ohio, and the Bank are subject to a capital‐based franchise tax in the state of Ohio. The Company and the Bank are no longer subject to examination by taxing authorities for years before December 31, 2010.

	13	EMPLOYEE BENEFITS
	Retirement Plan
	The Bank maintains section 401(k) employee savings and investment plans for all full-time employees and officers of the Bank with more than one year of service. The Bank's contributions to the plans are based on 50 percent matching of voluntary contributions up to 6 percent of compensation. An eligible employee can contribute up to 100 percent of salary. Employee contributions are vested at all times, and MBC contributions are fully vested after six years beginning at the second year in 20 percent increments. EB contributions are vested at 25 percent for less than a year of employment, 50 percent after one year, 75 percent after two years, and fully vested after three years. Contributions for 2013, 2012, and 2011 to these plans amounted to $155,000, $125,000, and $104,000, respectively.
	Supplemental Retirement Plan
	MBC maintains a Directors’ Retirement Plan to provide postretirement payments over a ten-year period to members of the Board of Directors who have completed five or more years of service. The plan requires payment of 25 percent of the final average annual board fees paid to a director in the three years preceding the director’s retirement.
	The following table illustrates the components of the projected payments for the Directors’ Retirement Plan for the years ended:
				Projected
				Payments
	2014			$	34,000
	2015				34,000
	2016				29,000
	2017				23,000
	2018				18,000
	Thereafter				23,000
	Total			$	161,000
	The retirement plan is available solely for nonemployee directors of The Middlefield Banking Company, but the Bank has not entered into any additional retirement arrangements for nonemployee directors since 2001. All director participants have retired.
	Executive Deferred Compensation Plan
	The Company maintains an Executive Deferred Compensation Plan (the “Plan”) to provide post-retirement payments to members of senior management. The Plan agreements are noncontributory, defined contribution arrangements that provide supplemental retirement income benefits to five officers, with contributions made solely by the Banks. During 2013, 2012, and 2011, the Company contributed $120,000, $139,000, and $91,000, respectively, to the Plan.
	Stock Option and Restricted Stock Plan
	The Company maintains a stock option and restricted stock plan (“the Plan”) for granting incentive stock options, nonqualified stock options, and restricted stock to key officers and employees and nonemployee directors of the Company. A total of 160,000 shares of authorized and unissued or issued common stock are reserved for issuance under the Plan, which expires ten years from the date of stockholder ratification. The per share exercise price of an option granted will not be less than the fair value of a share of common stock on the date the option is granted.

	14	COMMITMENTS
	In the normal course of business, there are various outstanding commitments and certain contingent liabilities which are not reflected in the accompanying consolidated financial statements. These commitments and contingent liabilities represent financial instruments with off-balance sheet risk. The contract or notional amounts of those instruments reflect the extent of involvement in particular types of financial instruments which were composed of the following:
	(Dollar amounts in thousands)		2013			2012
	Commitments to extend credit		$	120,861		$	91,854
	Standby letters of credit			4,809			281
	Total		$	125,670		$	92,135
	These instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the Consolidated Balance Sheet. The Company’s exposure to credit loss, in the event of nonperformance by the other parties to the financial instruments, is represented by the contractual amounts as disclosed. The Company minimizes its exposure to credit loss under these commitments by subjecting them to credit approval and review procedures and collateral requirements as deemed necessary. Commitments generally have fixed expiration dates within one year of their origination.
	Standby letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. Performance letters of credit represent conditional commitments issued by the Company to guarantee the performance of a customer to a third party. These instruments are issued primarily to support bid or performance-related contracts. The coverage period for these instruments is typically a one-year period with an annual renewal option subject to prior approval by management. Fees earned from the issuance of these letters are recognized over the coverage period. For secured letters of credit, the collateral is typically bank deposit instruments or customer business assets.
	Leasing Arrangements
	The Company leases certain of its banking facilities under operating leases which contain certain renewal options. As of December 31, 2013, approximate future minimum rental payments, including the renewal options under these leases, are as follows (in thousands):
	2014				221
	2015				226
	2016				230
	2017				238
	2018				240
	Thereafter				203
				$	1,358
	The above amounts represent minimum rentals not adjusted for possible future increases due to escalation provisions and assume that all renewal option periods will be exercised by the Company. Rent expense approximated $301,000, $269,000, and $248,000 for the years ended December 31, 2013, 2012, and 2011, respectively.

	15	REGULATORY RESTRICTIONS
	The Company is subject to the regulatory requirements of the Federal Reserve System as a multi-bank holding company. The affiliate banks are subject to regulations of the Federal Deposit Insurance Corporation (“FDIC”) and the State of Ohio, Division of Financial Institutions.
	In February of 2011 Emerald Bank agreed with the FDIC and the Ohio Division of Financial Institutions that Emerald Bank will take specified actions to correct weaknesses in the bank’s condition and operations. The actions that Emerald Bank agreed to take include reducing the bank’s concentration of credit in non-owner occupied 1 - 4 family residential mortgage loans, reducing delinquent and classified loans, enhancing credit administration for non-owner occupied residential real estate, developing plans for the reduction of borrower indebtedness on classified and delinquent credits, implementing an earnings improvement plan, maintaining leverage capital of at least 9%, revising the bank’s methodology for calculating and determining the adequacy of the allowance for loan and lease loss, and providing to the FDIC and the ODFI notice of proposed dividend payments at least 30 days in advance.
	We have conducted an evaluation and reorganization of lending and credit administration personnel, retained collection and workout personnel, and sold $5.8 million of nonperforming assets EMORECO, Inc., Middlefield Banc Corp.’s nonbank-asset resolution subsidiary established in the fourth quarter of 2009. Middlefield Banc Corp. provided capital of $500,000 to Emerald Bank in 2010 and $1.5 million in 2011 so that Emerald Bank would achieve the elevated 9% leverage capital level. At December 31, 2013 Emerald Bank’s leverage ratio was 10.92%.
	In addition to Emerald Bank maintaining leverage capital of at least 9%, Middlefield Banc Corp. committed to the Federal Reserve that Middlefield Banc Corp. will maintain tier 1 leverage capital of at least 7.25% and total risk-based capital of at least 12%, both at the level of the holding company and at the level of The Middlefield Banking Company.
	Cash Requirements
	The Cleveland district Federal Reserve Bank requires the Company to maintain certain average reserve balances. As of December 31, 2013 and 2012, the Company had required reserves of $7.4 million and $7.1 million comprising vault cash and a depository amount held with the Federal Reserve Bank.
	Loans
	Federal law prevents the Company from borrowing from the Banks unless the loans are secured by specific obligations. Further, such secured loans are limited in amount of 10 percent of the Banks’ common stock and capital surplus.
	Dividends
	MBC and EB are subject to dividend restrictions that generally limit the amount of dividends that can be paid by an Ohio state-chartered bank. Under the Ohio Banking Code, cash dividends may not exceed net profits as defined for that year combined with retained net profits for the two preceding years less any required transfers to surplus. Under this formula the amount available for payment of dividends for 2014 approximates $10.4 million plus 2014 profits retained up to the date of the dividend declaration.
	Potential Restrictions
	On or about January 14, 2013 an investor to whom we sold a total of 196,635 shares in April of 2012, constituting 9.9% of our stock, obtained from the Ohio Division of Financial Institutions and the Federal Reserve Bank of Cleveland regulatory clearance to acquire up to 24.99% of our stock. The August 15, 2011 Stock Purchase Agreement, as amended, under which we sold shares to the investor provided for sale of up to 24.99% of our stock, subject to the investor obtaining regulatory clearance and subject to other conditions. Although we disclosed in a Form 8-K Current Report filed with the SEC on January 18, 2013 that sale of additional shares to the investor under the terms of the Stock Purchase Agreement will not occur, if the investor nevertheless acquires shares and increases his ownership to 10% or more of our common stock, whether acquiring the shares on the open market or from us, we will become subject to additional restrictions under the terms of the regulatory clearance issued to the investor by the Ohio Division of Financial Institutions. Specifically, for three years after the investor becomes an owner of 10% or more of our stock, we would have to obtain advance approval of the ODFI in order for The Middlefield Banking Company to pay a dividend to Middlefield Banc Corp., and for 12 months we would have to obtain advance written approval of the ODFI for any changes in the composition of Middlefield Banc Corp.’s board or executive management.

Regulatory Capital Requirements under Banking Regulations [Text Block]	'
	16	REGULATORY CAPITAL
	Federal regulations require the Company and the Banks to maintain minimum amounts of capital. Specifically, each is required to maintain certain minimum dollar amounts and ratios of Total and Tier I capital to risk-weighted assets and of Tier I capital to average total assets.
	In addition to the capital requirements, the Federal Deposit Insurance Corporation Improvement Act (“FDICIA”) established five capital categories ranging from “well capitalized” to “critically undercapitalized.” Should any institution fail to meet the requirements to be considered “adequately capitalized,” it would become subject to a series of increasingly restrictive regulatory actions.
	As of December 31, 2013 and 2012, the FDIC categorized the Banks as well capitalized under the regulatory framework for prompt corrective action. To be classified as a well capitalized financial institution, Total risk-based, Tier 1 risk-based, and Tier 1 Leverage capital ratios must be at least 10 percent, 6 percent, and 5 percent, respectively.
	The Company’s and its subsidiaries’ actual capital ratios are presented in the following table that shows that all regulatory capital requirements were met as of December 31, 2013.

	17	FAIR VALUE DISCLOSURE MEASUREMENTS
	The following disclosures show the hierarchal disclosure framework associated with the level of pricing observations utilized in measuring assets and liabilities at fair value. The three broad levels defined by U.S. generally accepted accounting principles are as follows:
	Level I:	Quoted prices are available in active markets for identical assets or liabilities as of the reported date.
	Level II:	Pricing inputs are other than the quoted prices in active markets, which are either directly or indirectly observable as of the reported date. The nature of these assets and liabilities includes items for which quoted prices are available but traded less frequently and items that are fair-valued using other financial instruments, the parameters of which can be directly observed.
	Level III:	Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable.
	This hierarchy requires the use of observable market data when available.
	The following table presents the assets reported on the Consolidated Balance Sheet at their fair value as of December 31, 2013 and 2012, by level within the fair value hierarchy. Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement.

	Total		$	5	$	194,467		$	-			$	194,472
	Financial instruments are considered Level III when their values are determined using pricing models, discounted cash flow methodologies or similar techniques and at least one significant model assumption or input is unobservable. In addition to these unobservable inputs, the valuation models for Level III financial instruments typically also rely on a number of inputs that are readily observable either directly or indirectly. Level III financial instruments also include those for which the determination of fair value requires significant management judgment or estimation.
	The following tables present the assets measured on a non-recurring basis on the Consolidated Balance Sheet at their fair value by level within the fair value hierarchy. Impaired loans that are collateral dependent are written down to fair value through the establishment of specific reserves. Techniques used to value the collateral that secure the impaired loan include: quoted market prices for identical assets classified as Level I inputs and observable inputs, employed by certified appraisers, for similar assets classified as Level II inputs. In cases where valuation techniques included inputs that are unobservable and are based on estimates and assumptions developed by management based on the best information available under each circumstance, the asset valuation is classified as Level III inputs.

Financial instruments are defined as cash, evidence of ownership interest in an entity, or a contract which creates an obligation or right to receive or deliver cash or another financial instrument from/to a second entity on potentially favorable or unfavorable terms.
Fair value is defined as the amount at which a financial instrument could be exchanged in a current transaction between willing parties other than in a forced liquidation sale. If a quoted market price is available for a financial instrument, the estimated fair value would be calculated based upon the market price per trading unit of the instrument.
If no readily available market exists, the fair value estimates for financial instruments should be based upon management’s judgment regarding current economic conditions, interest rate risk, expected cash flows, future estimated losses, and other factors as determined through various option pricing formulas or simulation modeling. Since many of these assumptions result from judgments made by management based upon estimates which are inherently uncertain, the resulting estimated fair values may not be indicative of the amount realizable in the sale of a particular financial instrument. In addition, changes in assumptions on which the estimated fair values are based may have a significant impact on the resulting estimated fair values.
As certain assets such as deferred tax assets and premises and equipment are not considered financial instruments, the estimated fair value of financial instruments would not represent the full value of the Company.
The Company employed simulation modeling in determining the estimated fair value of financial instruments for which quoted market prices were not available based upon the following assumptions:
Cash and Cash Equivalents, Federal Home Loan Bank Stock, Accrued Interest Receivable, Accrued Interest Payable, and Short-Term Borrowings
The fair value is equal to the current carrying value.
Bank-Owned Life Insurance
The fair value is equal to the cash surrender value of the life insurance policies.
Investment Securities Available for Sale
The fair value of investment securities is equal to the available quoted market price. If no quoted market price is available, fair value is estimated using the quoted market price for similar securities.
Loans
The fair value is estimated by discounting future cash flows using current market inputs at which loans with similar terms and qualities would be made to borrowers of similar credit quality. Where quoted market prices were available, primarily for certain residential mortgage loans, such market rates were utilized as estimates for fair value.
Deposits and Other Borrowed Funds
The fair values of certificates of deposit and other borrowed funds are based on the discounted value of contractual cash flows. The discount rates are estimated using rates currently offered for similar instruments with similar remaining maturities. Demand, savings, and money market deposits are valued at the amount payable on demand as of year-end.
Commitments to Extend Credit
These financial instruments are generally not subject to sale, and estimated fair values are not readily available. The carrying value, represented by the net deferred fee arising from the unrecognized commitment or letter of credit, and the fair value, determined by discounting the remaining contractual fee over the term of the commitment using fees currently charged to enter into similar agreements with similar credit risk, are not considered material for disclosure. The contractual amounts of unfunded commitments and letters of credit are presented in Note 14.

Accounting Policies, by Policy (Policies)	12 Months Ended
	Dec. 31, 2013
Accounting Policies [Abstract]	'
Basis of Accounting, Policy [Policy Text Block]	'
	Nature of Operations and Basis of Presentation
	Middlefield Banc Corp. (the “Company”) is an Ohio corporation organized to become the holding company of The Middlefield Banking Company (“MBC”). MBC is a state-chartered bank located in Ohio. On April 19, 2007, Middlefield Banc Corp. acquired Emerald Bank (“EB”), an Ohio-chartered commercial bank headquartered in Dublin, Ohio. On October 23, 2009, the Company established an asset resolution subsidiary named EMORECO, Inc. The Company and its subsidiaries derive substantially all of their income from banking and bank-related services, which includes interest earnings on residential real estate, commercial mortgage, commercial and consumer financings as well as interest earnings on investment securities and deposit services to its customers through ten locations. The Company is supervised by the Board of Governors of the Federal Reserve System, while MBC and EB are subject to regulation and supervision by the Federal Deposit Insurance Corporation and the Ohio Division of Financial Institutions. EB merged into MBC on January 20, 2014.
	The consolidated financial statements of the Company include its wholly-owned subsidiaries, MBC, EB, and EMORECO, Inc. (the “Banks”). Significant intercompany items have been eliminated in preparing the consolidated financial statements.
	The financial statements have been prepared in conformity with U.S. generally accepted accounting principles. In preparing the financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the balance sheet date and revenues and expenses for the period. Actual results could differ from those estimates.
Marketable Securities, Policy [Policy Text Block]	'
	Investment Securities
	Investment securities are classified at the time of purchase, based on management’s intention and ability, as securities held to maturity or securities available for sale. Debt securities acquired with the intent and ability to hold to maturity are stated at cost adjusted for amortization of premium and accretion of discount, which are computed using a level yield method and recognized as adjustments of interest income. Certain other debt securities have been classified as available for sale to serve principally as a source of liquidity. Unrealized holding gains and losses for available-for-sale securities are reported as a separate component of stockholders’ equity, net of tax, until realized. Realized security gains and losses are computed using the specific identification method. Interest and dividends on investment securities are recognized as income when earned.
	Common stock of the Federal Home Loan Bank (“FHLB”) represents ownership in an institution that is wholly owned by other financial institutions. This equity security is accounted for at cost and classified with other assets. The FHLB of Cincinnati has reported profits for 2013 and 2012, remains in compliance with regulatory capital and liquidity requirements, and continues to pay dividends on the stock and make redemptions at the par value. With consideration given to these factors, management concluded that the stock was not impaired at December 31, 2013 or 2012.
	Securities are evaluated on at least a quarterly basis and more frequently when economic or market conditions warrant such an evaluation to determine whether a decline in their value is other than temporary. For debt securities, management considers whether the present value of cash flows expected to be collected are less than the security’s amortized cost basis (the difference defined as the credit loss), the magnitude and duration of the decline, the reasons underlying the decline and the Company’s intent to sell the security or whether it is more likely than not that the Company would be required to sell the security before its anticipated recovery in market value, to determine whether the loss in value is other than temporary. Once a decline in value is determined to be other than temporary, if the Company does not intend to sell the security, and it is more likely than not that it will not be required to sell the security, before recovery of the security’s amortized cost basis, the charge to earnings is limited to the amount of credit loss. Any remaining difference between fair value and amortized cost (the difference defined as the non-credit portion) is recognized in other comprehensive income, net of applicable taxes. Otherwise, the entire difference between fair value and amortized cost is charged to earnings. For equity securities where the fair value has been significantly below cost for one year, the Company’s policy is to recognize an impairment loss unless sufficient evidence is available that the decline is not other than temporary and a recovery period can be predicted.
Finance, Loans and Leases Receivable, Policy [Policy Text Block]	'
	Loans
	Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff generally are reported at their outstanding unpaid principal balances net of the allowance for loan and lease loss. Interest income is recognized as income when earned on the accrual method. The accrual of interest is discontinued on a loan when management believes, after considering economic and business conditions, the borrower’s financial condition is such that collection of interest is doubtful. Interest received on nonaccrual loans is recorded as income or applied against principal according to management’s judgment as to the collectability of such principal.
	Loan origination fees and certain direct loan origination costs are being deferred and the net amount amortized as an adjustment of the related loan’s yield. Management is amortizing these amounts over the contractual life of the related loans.
Loans and Leases Receivable, Allowance for Loan Losses Policy [Policy Text Block]	'
	Allowance for Loan and Lease Loss
	The allowance for loan and lease loss represents the amount which management estimates is adequate to provide for probable loan losses inherent in the loan portfolio. The allowance method is used in providing for loan losses. Accordingly, all loan losses are charged to the allowance, and all recoveries are credited to it. The allowance for loan and lease loss is established through a provision for loan losses which is charged to operations. The provision is based on management’s periodic evaluation of the adequacy of the allowance for loan and lease loss, which encompasses the overall risk characteristics of the various portfolio segments, past experience with losses, the impact of economic conditions on borrowers, and other relevant factors. The estimates used in determining the adequacy of the allowance for loan and lease loss, including the amounts and timing of future cash flows expected on impaired loans, are particularly susceptible to significant change in the near term.
	A loan is considered impaired when it is probable the borrower will not repay the loan according to the original contractual terms of the loan agreement. Management has determined that first mortgage loans on one-to-four family properties and all consumer loans represent large groups of smaller-balance homogeneous loans that are to be collectively evaluated. Loans that experience insignificant payment delays, which are defined as 90 days or less, generally are not classified as impaired. A loan is not impaired during a period of delay in payment if the Company expects to collect all amounts due, including interest accrued, at the contractual interest rate for the period of delay. All loans identified as impaired are evaluated independently by management. The Company estimates credit losses on impaired loans based on the present value of expected cash flows or the fair value of the underlying collateral if the loan repayment is expected to come from the sale or operation of such collateral. Impaired loans, or portions thereof, are charged off when it is determined a realized loss has occurred. Until such time, an allowance for loan and lease loss is maintained for estimated losses. Cash receipts on impaired loans are applied first to accrued interest receivable unless otherwise required by the loan terms, except when an impaired loan is also a nonaccrual loan, in which case the portion of the payment related to interest is recognized as income.
	Mortgage loans secured by one-to-four family properties and all consumer loans are large groups of smaller-balance homogeneous loans and are measured for impairment collectively. Management determines the significance of payment delays on a case-by-case basis, taking into consideration all circumstances concerning the loan, the creditworthiness and payment history of the borrower, the length of the payment delay, and the amount of shortfall in relation to the principal and interest owed.
Property, Plant and Equipment, Policy [Policy Text Block]	'
	Premises and Equipment
	Land is carried at cost. Premises and equipment are stated at cost net of accumulated depreciation. Depreciation is computed on the straight-line method over the estimated useful lives of the assets, which range from 3 to 20 years for furniture, fixtures, and equipment and 3 to 40 years for buildings and leasehold improvements. Expenditures for maintenance and repairs are charged against income as incurred. Costs of major additions and improvements are capitalized.
Goodwill and Intangible Assets, Goodwill, Policy [Policy Text Block]	'
	Goodwill
	The Company accounts for goodwill using a two-step process for testing the impairment of goodwill on at least an annual basis. This approach could cause more volatility in the Company’s reported net income because impairment losses, if any, could occur irregularly and in varying amounts. No impairment of goodwill was recognized in any of the periods presented.
Intangible Assets, Finite-Lived, Policy [Policy Text Block]	'
	Intangible Assets
	Intangible assets include core deposit intangibles, which are a measure of the value of consumer demand and savings deposits acquired in business combinations accounted for as purchases. The core deposit intangibles are being amortized to expense over a 10 year life on a straight-line basis. The recoverability of the carrying value of intangible assets is evaluated on an ongoing basis, and permanent declines in value, if any, are charged to expense.
Life Insurance, Corporate or Bank Owned [Text Block]	'
	Bank-Owned Life Insurance (“BOLI”)
	The Company owns insurance on the lives of a certain group of key employees. The policies were purchased to help offset the increase in the costs of various fringe benefit plans including healthcare. The cash surrender value of these policies is included as an asset on the Consolidated Balance Sheet and any increases in the cash surrender value are recorded as noninterest income on the Consolidated Statement of Income. In the event of the death of an insured individual under these policies, the Company would receive a death benefit, which would be recorded as noninterest income.
Real Estate, Policy [Policy Text Block]	'
	Other Real Estate Owned
	Real estate properties acquired through foreclosure are initially recorded at fair value at the date of foreclosure, establishing a new cost basis. After foreclosure, management periodically performs valuations and the real estate is carried at the lower of cost or fair value less estimated cost to sell. Revenue and expenses from operations of the properties, gains or losses on sales and additions to the valuation allowance are included in operating results.
Income Tax, Policy [Policy Text Block]	'
	Income Taxes
	The Company and its subsidiaries file a consolidated federal income tax return. 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. As changes in tax laws or rates are enacted, deferred tax assets and liabilities are adjusted through the provision for income taxes.
Earnings Per Share, Policy [Policy Text Block]	'
	Earnings Per Share
	The Company provides dual presentation of basic and diluted earnings per share. Basic earnings per share are calculated utilizing net income as reported in the numerator and average shares outstanding in the denominator. The computation of diluted earnings per share differs in that the dilutive effects of any stock options, warrants, and convertible securities are adjusted in the denominator.
Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]	'
	Stock-Based Compensation
	The Company accounts for stock compensation based on the grant date fair value of all share-based payment awards that are expected to vest, including employee share options to be recognized as employee compensation expense over the requisite service period.
	For purposes of computing results, the Company estimated the fair values of stock options using the Black-Scholes option-pricing model. The model requires the use of subjective assumptions that can materially affect fair value estimates. The fair value of each option is amortized into compensation expense on a straight-line basis between the grant date for the option and each vesting date. The fair value of each stock option granted was estimated using the following weighted-average assumptions:
	Grant	Expected			Risk-Free			Expected		Expected
	Year	Dividend			Interest Rate			Volatility		Life (in years)
		Yield
	2011		5.82	%		3	%		21.78		9.96
	During the years ended December 31, 2013, 2012, and 2011, the Company recorded $0, $0, and $16,000, of compensation cost related to vested stock options. As of December 31, 2013, there was no unrecognized compensation cost related to unvested stock options. The weighted-average fair value of the stock option granted for 2011 was $1.75.
	The Company also issued 1,722 and 2,400 shares of restricted stock and recorded stock–based compensation expense of $32,000 and $43,000 in 2012 and 2011, respectively. There were no shares of restricted stock issued in 2013.
	For the year ended December 31, 2013, 21,112 options were exercised resulting in net proceeds of $77,000.
Cash and Cash Equivalents, Policy [Policy Text Block]	'
	Cash Flow Information
	The Company has defined cash and cash equivalents as those amounts included in the Consolidated Balance Sheet captions as “Cash and due from banks” and “Federal funds sold” with original maturities of less than 90 days.
Advertising Costs, Policy [Policy Text Block]	'
	Advertising Costs
	Advertising costs are expensed as incurred. Advertising expenses amounted to $445,000, $423,000, and $439,000, for 2013, 2012, and 2011, respectively.
Reclassification, Policy [Policy Text Block]	'
	Reclassification of Comparative Amounts
	Certain comparative amounts for prior years have been reclassified to conform to current-year presentations. Such reclassifications did not affect net income or retained earnings.
New Accounting Pronouncements, Policy [Policy Text Block]	'
	Recent Accounting Pronouncements
	In February 2013, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2013-02, Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income. The standard requires that companies present either in a single note or parenthetically on the face of the financial statements, the effect of significant amounts reclassified from each component of accumulated other comprehensive income based on its source and the income statement line items affected by the reclassification. The new requirements will take effect for public companies in fiscal years, and interim periods within those years, beginning after December 15, 2012. The Company adopted this standard on January 1, 2013. The effect of adopting this standard increased our disclosure surrounding reclassification items out of accumulated other comprehensive income.
	In February 2013, the FASB issued ASU 2013-04, Obligations Resulting from Joint and Several Liability Arrangements for Which the Total Amount of the Obligation is Fixed at the Reporting Date. The ASU requires the measurement of obligations resulting from joint and several liability arrangements for which the total amount of the obligation is fixed at the reporting date as the sum of the amount the reporting entity agreed to pay on the basis of its arrangement with its co-obligors as well as any additional amount that the entity expects to pay on behalf of its co-obligors. The new standard is effective retrospectively for fiscal years and interim periods within those years, beginning after December 15, 2013, and early adoption is permitted. This ASU is not expected to have a significant impact on the Company’s financial statements.
	In July 2013, the FASB issued ASU 2013-11, Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists. This Update applies to all entities that have unrecognized tax benefits when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists at the reporting date. An unrecognized tax benefit, or a portion of an unrecognized tax benefit, should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward, except as follows. To the extent a net operating loss carryforward, a similar tax loss, or a tax credit carryforward is not available at the reporting date under the tax law of the applicable jurisdiction to settle any additional income taxes that would result from the disallowance of a tax position or the tax law of the applicable jurisdiction does not require the entity to use, and the entity does not intend to use, the deferred tax asset for such purpose, the unrecognized tax benefit should be presented in the financial statements as a liability and should not be combined with deferred tax assets. The assessment of whether a deferred tax asset is available is based on the unrecognized tax benefit and deferred tax asset that exist at the reporting date and should be made presuming disallowance of the tax position at the reporting date. The amendments in this Update are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. For nonpublic entities, the amendments are effective for fiscal years, and interim periods within those years, beginning after December 15, 2014. Early adoption is permitted. The amendments should be applied prospectively to all unrecognized tax benefits that exist at the effective date. Retrospective application is permitted.
	In January 2014, FASB issued ASU 2014-01, Investments – Equity Method and Join Ventures (Topic 323): Accounting for Investments in Qualified Affordable Housing Projects. The amendments in this Update permit reporting entities to make an accounting policy election to account for their investments in qualified affordable housing projects using the proportional amortization method if certain conditions are met. Under the proportional amortization method, an entity amortizes the initial cost of the investment in proportion to the tax credits and other tax benefits received and recognizes the net investment performance in the income statement as a component of income tax expense (benefit). The amendments in this Update should be applied retrospectively to all periods presented. A reporting entity that uses the effective yield method to account for its investments in qualified affordable housing projects before the date of adoption may continue to apply the effective yield method for those preexisting investments. The amendments in this Update are effective for public business entities for annual periods and interim reporting periods within those annual periods, beginning after December 15, 2014. Early adoption is permitted. This ASU is not expected to have a significant impact on the Company’s financial statements.
	In January 2014, the FASB issued ASU 2014-04, Receivables – Troubled Debt Restructurings by Creditors (Subtopic 310-40): Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure. The amendments in this Update clarify 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 in this Update are effective for public business entities for annual periods, and interim periods within those annual periods, beginning after December 15, 2014. An entity can elect to adopt the amendments in this Update using either a modified retrospective transition method or a prospective transition method. This ASU is not expected to have a significant impact on the Company’s financial statement.
