Shareholders' Equity [Abstract]
Stockholders' Equity	Shareholders’ Equity Preferred Stock The Corporation is authorized to issue up to 1,000,000 shares of Voting Preferred Stock, no par value. The Board of Directors of the Corporation is authorized to provide for the issuance of one or more series of Voting Preferred Stock and establish the dividend rate, dividend dates, whether dividends are cumulative, liquidation prices, redemption rights and prices, sinking fund requirements, conversion rights, and restrictions on the issuance of any series of Voting Preferred Stock. The Voting Preferred Stock may rank prior to the common stock in dividends, liquidation preferences, or both. The Corporation has authorized 150,000 Series A Voting Preferred Shares, none of which have been issued. As of December 31, 2013 and 2012, 7,689 and 18,880 shares of the Corporation’s Series B Preferred Stock were issued and outstanding. On December 12, 2008, the Corporation issued 25,223 shares of its Fixed Rate Cumulative Perpetual Preferred Stock, Series B, $1,000 per share liquidation preference (“Series B Preferred Stock”) to the U.S. Department of the Treasury (the "Treasury")in the TARP Capital Purchase Program for a purchase price of approximately $25,223. Holders of the shares of Series B Preferred Stock are entitled to receive if, as and when declared by our Board of Directors or duly authorized committee of the Board, out of assets legally available for payment, cumulative cash dividends at a rate per annum of 5% per share on liquidation preference of $1,000 per share of Series B Preferred Stock with respect to each dividend period. From and after February 15, 2014, holders of Series B Preferred Stock are entitled to receive cumulative cash dividends at a rate per annum of 9% per share on a liquidation preference of $1,000 per Series B Preferred Stock. In connection with that issuance, the Corporation also issued a warrant to the Treasury to purchase 561,343 common shares of the Corporation at an exercise price of $6.74 per share (the “Warrant”). Dividends are payable quarterly in arrears on each February 15th, May 15th, August 15th and November 15th on shares of Series B Preferred Stock. Dividends payable during any dividend period are computed on the basis of a 360-day year consisting of twelve 30-day months. Dividends payable with respect to the Series B Preferred Stock are payable to holders of record of shares of Series B Preferred Stock on the date that is 15 calendar days immediately preceding the applicable dividend payment date or such other record date as the board of directors or any duly authorized committee of the board determines, so long as such record date is not more than 60 nor less than 10 days prior to the applicable dividend payment date. As part of the Treasury’s strategy for winding down its remaining investment in the Troubled Asset Relief Program (TARP), particularly in community banks, the Treasury conducted various public auctions of TARP preferred stock in 2012. On June 19, 2012 the Treasury completed the offer and sale of all 25,223 shares of the Corporation's Series B Preferred Stock. The underwriters in the offering purchased the Series B Preferred Stock from the U.S. Department of Treasury at a price of $856.13 per share. The shares were subsequently sold to the public through a modified Dutch auction at an initial public offering price of $869.17 per share. The Corporation did not receive any of the proceeds from the offering. During the third quarter 2012, the Corporation entered into a Warrant Repurchase Agreement to purchase the Warrant issued. The Warrant was immediately exercisable for 561,343 shares of the Corporation's common shares at an exercise price of $6.74 per common share. The Warrant was transferrable and could be exercised at any time on or before July 2, 2012. The Corporation negotiated a repurchase of Warrants at a mutually agreed upon price of $1.53 per share, or $860 with the Treasury. The repurchase of the Warrant occurred in July 2012 and reduced equity by the amount of the purchase price. Following settlement of the Warrant repurchase, the Treasury had no remaining investment in the Corporation. In the fourth quarter of 2012, the Corporation completed the repurchase of $6,343 in face liquidation amount, or approximately 25% of the outstanding shares, of its Series B Preferred Stock in exchange for cash at a price representing a discount to par value. The transaction was funded by cash from accumulated earnings and excess capital. As a result of the discount on the purchase price, the Corporation recognized an increase to retained earnings of $163. As of December 31, 2012, 18,880 shares of the Corporation’s Series B Preferred Stock remained issued and outstanding. On March 15, 2013, the Corporation completed the exchange (the “Exchange”) of newly issued Common Shares, $1.00 par value per share, of the Company (“Common Shares”) for shares of the Company’s Fixed Rate Cumulative Perpetual Preferred Stock, Series B, $1,000 per share liquidation preference (“Series B Preferred Stock”) with certain institutional and private investors (the "Sellers"). In the Exchange, the Corporation issued an aggregate of 1,359,348 Common Shares at a price of $7.16 per share to the Sellers in exchange for an aggregate of 9,733 shares of Series B Preferred Stock at a price of 100% of the per share liquidation preference, or $1,000 per share. The Corporation also delivered cash to the Sellers in lieu of fractional Common Shares and cash in an amount equal to the accrued and unpaid dividends due on the shares of Series B Preferred Stock. Following the completion of the Exchange, an aggregate of 9,147 shares of the Series B Preferred Stock remained outstanding. On December 12, 2013, the Corporation entered into a common shares purchase agreement (the “Purchase Agreement”) with certain investors party thereto (the “Investors”), which included certain third-party investors and certain directors of the Corporation. The transactions were approved by the Board of Directors of the Corporation, by a majority of the disinterested directors of the Corporation and by the Corporation’s Audit and Finance Committee. Pursuant to the Purchase Agreement, the Corporation sold to the Investors an aggregate of 367,321 Common Shares at a purchase price of $9.9087 per share (except that Investors who are directors of the Corporation or are related thereto paid $10.30 per share), for an aggregate purchase price of $3.68 million. The Purchase Agreement, among other things, provided the Investors with certain registration rights, pursuant to which the Corporation filed a Registration Statement on Form S-3 with the SEC, which was declared effective on January 16, 2014. Following the completion of the issuance and sale of Common Shares pursuant to the Purchase Agreement, on December 17, 2013, the Corporation issued a notice of redemption of all 9,147 remaining shares of Series B Preferred Stock, to be funded with the proceeds of the sale of Common Shares along with cash from $3,000,000 in borrowings under the Corporation’s line of credit with an unaffiliated financial institution and from the Corporation’s accumulated earnings and excess capital. On January 17, 2014, the Corporation completed the retirement of the remaining shares of Series B Preferred Stock for an aggregate price of $9,147,000, the face liquidation amount of the shares, plus approximately $74,000 of accrued but unpaid dividends. The Corporation repurchased 1,458 of such shares in a private transaction in December 2013 and redeemed the remaining 7,689 shares of Series B Preferred Stock on the January 17, 2014 redemption date. Additional information regarding the redemption of Series B Preferred Stock is included in Note 24 (Subsequent Events) in the notes to the consolidated financial statements. Common Stock The Corporation is authorized to issue up to 15,000,000 common shares. Common shares issued were 10,001,717 at December 31, 2013 and 8,272,548 at December 31, 2012. Common shares outstanding were 9,673,523 and 7,944,354 at December 31, 2013 and December 31, 2012, respectively. Common Shares Repurchase Plan and Treasury Shares On July 28, 2005, the Board of Directors authorized the repurchase of up to 5% of the outstanding common shares of the Corporation, or approximately 332,000 shares. The repurchased shares are expected to be used primarily for qualified employee benefit plans, incentive stock option plans, stock dividends and other corporate purposes. At December 31, 2013 and December 31, 2012, the Corporation held 328,194 common shares as treasury shares under this plan at a total cost of $6,092. Shareholder Rights Plan On October 25, 2010, the Board of Directors of the Corporation adopted a Shareholder Rights Plan which replaced the Corporation’s original rights plan adopted October 24, 2000 which expired in October 2010. The rights plan is intended to discourage a potential acquirer from exceeding a prescribed ownership level in the Corporation, without prior approval of the Board of Directors. If the prescribed level is exceeded, the rights become exercisable and, following a limited period for the Board of Directors to redeem the rights, allow shareholders, other than the potential acquirer that triggered the exercise of the rights, to purchase Preferred Share Units of the Corporation having characteristics comparable to the Corporation’s common shares, at 50% of market value. This would dilute the potential acquirer’s ownership level and voting power, potentially making an acquisition of the Corporation without prior Board approval prohibitively expensive. The Shareholder Rights Plan provided for the distribution of one Preferred Share Purchase Right as a dividend on each outstanding Common Share of the Corporation held as of the close of business on November 5, 2010. One Preferred Share Purchase Right will also be distributed for each common share issued after November 5, 2010. Each right entitles the registered holder to purchase from the Corporation units of a new series of Voting Preferred Shares, no par value, at 50% of market value, if a person or group acquires 10% or more of the Corporation’s Common Shares. Each Unit of the new Preferred Shares has terms intended to make it the economic equivalent of one Common share. LNBB Direct Stock Purchase and Dividend Reinvestment Plan The Board of Directors adopted the LNBB Direct Stock Purchase and Dividend Reinvestment Plan (the Plan) effective June 2001, replacing the former LNB Bancorp, Inc. Dividend Reinvestment Plan. The Plan authorized the sale of 500,000 shares of the Corporation’s common shares to shareholders who choose to invest all or a portion of their cash dividends plus additional cash payments for the Corporation’s common stock. The Corporation did not issue shares pursuant to the Plan in 2013 and 9,936 shares were purchased in the open market at the market price on the date of purchase. Similarly, the Corporation did not issue shares pursuant to the Plan in 2011 while 13,795 shares were purchased in the open market at the market price on the date of purchase. Dividend Restrictions Dividends paid by the Bank are the primary source of funds available to the Corporation for payment of dividends to shareholders and for other working capital needs. The payment of dividends by the Bank to the Corporation is subject to restrictions by the Office of the Comptroller of Currency (OCC). These restrictions generally limit dividends to the current and prior two years’ retained earnings. In addition to these restrictions, as a practical matter, dividend payments cannot reduce regulatory capital levels below the Corporation’s regulatory capital requirements and minimum regulatory guidelines. Dividends declared and paid in 2013 were approved by the OCC prior to declaration and payment. Future dividend payments or debt issuance by the Corporation will be based on future earnings and the approval of the OCC. The Corporation is subject to various regulatory policies and requirements relating to the payment of dividends, including requirements to maintain adequate capital above regulatory minimums. The Board of Governors of the Federal Reserve System, or the Federal Reserve Board, is authorized to determine, under certain circumstances relating to the financial condition of a bank holding company, such as us, that the payment of dividends would be an unsafe or unsound practice and to prohibit payment thereof. In addition, the Corporation is subject to Ohio state laws relating to the payment of dividends.
