Retirement Benefits [Text Block] | NOTE 13 – 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 has been 5.00% since April 1, 2018. Matching contributions, if made, are immediately vested. Our 2023, 2022 and 2021 matching 401(k) contributions charged to expense were $2.3 million, $2.2 million and $2.1 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, which totaled $1.1 million as of both December 31, 2023 and 2022, 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 was less than $0.1 million during 2023, 2022, and 2021. The Mercantile Bank Corporation Employee Stock Purchase Plan of 2014 is a non-compensatory plan 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 totaled 1,410 and 1,388 in 2023 and 2022, respectively. As of December 31, 2023, there were approximately 234,500 shares available under our current plan.
