Compensation and Employee Benefit Plans [Text Block] | Note 1 3 . Employee Benefit Plans Defined Benefit Plans The Company maintains two nonqualified domestic, noncontributory defined benefit plans (the “Benefit Plans”) for key members of senior management and non-management directors. The Company’s unfunded Benefit Plans include the Supplemental Executive Retention Plan (“SERP”) and the Directors’ Supplemental Retirement Plan (“Directors’ Plan”). The SERP provides for a defined benefit, at normal retirement age, targeted at 35% of the participant’s projected final average compensation, subject to a defined maximum annual benefit. Benefits under the SERP generally become payable at age 62. The Directors’ Plan provides for a defined benefit, at normal retirement age, up to 100% of the participant’s highest consecutive three -year average compensation. Benefits under the Directors’ Plan generally become payable at age 70. The following table presents the changes in the aggregate actuarial benefit obligation during the periods indicated:

Deferred Compensation Plan The Company maintains deferred compensation agreements with certain current and former officers that provide benefit payments, over various periods, commencing at retirement or death. There were no accrued benefits, which are based on the present values of expected payments and estimated life expectancies, as of December 31, 2018 or 2017. There was no deferred compensation plan expense in 2018, compared to $11 thousand in 2017 and $60 thousand in 2016. Employee Welfare Plan The Company provides various medical, dental, vision, life, accidental death and dismemberment, and long-term disability insurance benefits to all full-time employees who elect coverage under this program. A third -party administrator manages the health plan. Monthly employer and employee contributions are made to a tax-exempt employee benefits trust where the third -party administrator processes and pays claims. As of December 31, 2018, stop-loss insurance coverage generally limits the Company’s risk of loss to $150 thousand for individual claims and $4.20 million for aggregate claims. Health plan expenses were $3.72 million in 2018, $3.50 million in 2017, and $3.48 million in 2016. Employee Stock Ownership and Savings Plan The Company maintains the Employee Stock Ownership and Savings Plan (“KSOP”) that consists of a 401 (k) savings feature that covers all employees that meet minimum eligibility requirements. The Company matches employee contributions at levels determined by the Board of Directors annually. These contributions are made in the first quarter following each plan year and employees must be employed on the last day of the plan year to be eligible. Matching contributions to qualified deferrals under the 401 (k) savings component of the KSOP totaled $1.06 million in 2018, $1.18 million in 2017, and $1.50 million in 2016. The KSOP held 366,969 shares of the Company’s common stock as of December 31, 2018, 387,935 shares as of December 31, 2017, and 410,384 shares as of December 31, 2016. Equity-Based Compensation Plans The Company maintains equity-based compensation plans to promote the long-term success of the Company by encouraging officers, employees, directors, and other individuals performing services for the Company to focus on critical long-range objectives. The Company’s equity-based compensation plans include the 2012 Omnibus Equity Compensation Plan ( “2012 Plan”), 2004 Omnibus Stock Option Plan, 2001 Director’s Option Plan, 1999 Stock Option Plan, and various other plans obtained through acquisitions. As of December 31, 2018, the 2012 Plan was the only plan available for the issuance of future grants. All plans issued or obtained before the 2012 Plan are frozen and no new grants may be issued; however, any options or awards unexercised and outstanding under those plans remain in effect per their respective terms. The 2012 Plan authorized 600,000 shares available for potential grants of incentive stock options, nonqualified stock options, performance awards, restricted stock, restricted stock units, stock appreciation rights, bonus stock, and stock awards. Grants issued under the 2012 Plan state the period of time the grant may be exercised, not to exceed more than ten years from the date granted. The Company’s Compensation and Retirement Committee determines the vesting period for each grant; however, if no vesting period is specified the vesting occurs in 25% increments on the first four anniversaries of the grant date. The following table presents the pre-tax compensation expense and excess tax benefit recognized in earnings for all equity-based compensation plans for the periods indicated:
