Employee Benefits [Abstract] |
Employee Benefits | Note 16: Employee Benefits The Company has instituted a long-term incentive program (LTI), with the objective of rewarding senior management with restricted shares of the Company, in addition to the existing stock option program (see Note 16). The Company has a retirement savings 401(k) plan covering substantially all employees. Employees contributing up to 4 percent of their compensation receive a Company match of 100 percent of the employee’s contribution. Employee contributions are vested immediately and the Company’s matching contributions are fully vested after three years of employment. Employer contributions charged to expense for 2017, 2016 and 2015 were $0.5, $0.4 and $0.4 million, respectively. Also, the Company has Supplemental Executive Retirement Plan (“SERP”) Agreements with certain active and retired officers. The agreements provide monthly payments for up to 15 years that equal 15 percent to 25 percent of average compensation prior to retirement or death. The charges to expense for the current agreements were $0.2, $0.03 and $0.2 million for 2017, 2016 and 2015, respectively. Additional life insurance is provided to certain officers through a bank-owned life insurance policy (“BOLI”). By way of a separate split-dollar agreement, the policy interests are divided between State Bank and the insured’s beneficiary. State Bank owns the policy cash value and a portion of the policy net death benefit, over and above the cash value assigned to the insured’s beneficiary. The cash surrender value of all life insurance policies totaled $16.5 and $13.7 million at December 31, 2017, and 2016, respectively. The Company has a noncontributory employee stock ownership plan (“ESOP”) covering substantially all employees of the Company and its subsidiaries. Voluntary contributions are made by the Company to the plan. Each eligible employee is vested based upon years of service, including prior years of service. The Company’s contributions to the account of each employee become fully vested after three years of service. Benefit expense for the value of the stock purchased is recorded equal to the fair market value of the stock when contributions, which are determined annually by the Board of Directors of the Company, are made to the ESOP. Allocated shares in the ESOP at December 31, 2017 and 2016, were 449,635 and 466,442, respectively. Dividends on allocated shares are recorded as dividends and charged to retained earnings. Compensation expense is recorded equal to the fair market value of the stock when contributions, which are determined annually by the Board of Directors of the Company, are made to the ESOP. ESOP expense for the years ended December 31, 2017, 2016 and 2015 was $0.2, $0.3 and $0.2 million, respectively.
