Compensation and Retirement Disclosure [Abstract]

The Company has a profit sharing and 401(k) plan for the benefit of substantially all employees subject to certain minimum age and service requirements. Under the 401(k) plan, the Company matched employee contributions to a maximum of 4.00% of annual compensation in 2014, 2015 and 2016. The Company's contribution pursuant to this formula was approximately $565,000, $539,000 and $439,000 for the years 2016, 2015 and 2014, respectively. Investments of the 401(k) plan are determined by a committee comprised of senior management. No investments in Company stock have been made by the 401(k) plan. Prior to January 1, 2015, the vesting schedule for the 401(k) plan began at 20 percent after two years of employment and graduated 20 percent each year until reaching 100 percent after six years of employment. Effective January 1, 2015, contributions to the 401(k) plan are vested immediately.

In December 2001, the Company initiated a postretirement benefit plan to provide retirement benefits to key officers and its Board of Directors and to provide death benefits for their designated beneficiaries. Under the postretirement benefit plan, the Company purchased life insurance contracts on the lives of the key officers and each director. The increase in cash surrender value of the contracts constitutes the Company's contribution to the postretirement benefit plan each year. Postretirement benefit plan participants are to be paid annual benefits for a specified number of years commencing upon retirement. Expenses incurred for benefits relating to the postretirement benefit plan were approximately $428,000, $413,000 and $422,000 for the years 2016, 2015 and 2014, respectively.

The Company is currently paying medical benefits for certain retired employees. The Company did not incur any postretirement medical benefits expense in 2016, 2015 and 2014 due to an excess accrual balance.
