Compensation and Retirement Disclosure [Abstract] |
Pension and Other Postretirement Benefits Disclosure [Text Block] | NOTE 15 – BENEFIT PLANS We have a 401(k) benefit plan that covers substantially all of our employees. The percent of our matching contributions to the 401(k) benefit plan is determined annually by the Board of Directors. The matching contribution was 3% as of January 1, 2012, and then increased to 4% as of October 1, 2012. Effective January 1, 2014, the matching contribution was increased to 4.25%. Matching contributions, if made, are immediately vested. Our 2014, 2013 and 2012 matching 401(k) contributions charged to expense were $0.9 million, $0.5 million and $0.4 million, respectively. We have a deferred compensation plan in which all persons serving on the Board of Directors may defer all or portions of their annual retainer and meeting fees, with distributions to be paid upon termination of service as a director or specific dates selected by the director. We also have a non-qualified deferred compensation program in which selected officers may defer all or portions of salary and bonus payments. The deferred amounts, totaling $3.7 million and $1.6 million as of December 31, 2014 and 2013, respectively, are categorized as other liabilities in the Consolidated Balance Sheets, and are paid interest at a rate equal to the Wall Street Journal Prime Rate. Interest expense is insignificant for all periods presented. The Mercantile Bank Corporation Employee Stock Purchase Plan of 2002 was replaced by the Mercantile Bank Corporation Employee Stock Purchase Plan of 2014 (herein after referred to as the “Stock Purchase Plans”) in June of 2014. The Stock Purchase Plans are non-compensatory plans intended to encourage full- and part-time employees of Mercantile and its subsidiaries to promote our best interests and to align employees’ interests with the interests of our shareholders by permitting employees to purchase shares of our common stock through regular payroll deductions. Shares are purchased on the last business day of each calendar quarter at a price equal to the consolidated closing bid price of our common stock reported on The Nasdaq Stock Market. A total of 250,000 shares of common stock may be issued under the existing plan; however, the number of shares may be adjusted to reflect any stock dividends and other changes in our capitalization. The number of shares issued under the Stock Purchase Plans totaled 1,150 and 1,098 in 2014 and 2013, respectively. As of December 31, 2014, there were 28,850 shares available under our current plan.
