(6) Employee Retirement Plans

The Company has a noncontributory defined benefit pension plan (the "Plan") that covers substantially all union employees previously employed by its wholly owned subsidiary, Corson Lime Company. In 1997, the Company sold substantially all of the assets of Corson Lime Company, and all benefits for participants in the Plan were frozen. During 1997 and 1998, the Company made contributions to the Plan that were intended to fully fund the benefits earned by the participants. The unfunded projected benefit obligation was $275 and $10 at December 31, 2014 and 2013, respectively. The Company recorded comprehensive loss of $81, net of $46 tax benefit, and comprehensive income of $197, net of $112 tax expense, and of $64, net of $36 tax expense, for the years ended December 31, 2014, 2013 and 2012, respectively. The Company made contributions of $0, $0 and $151 to the Plan in 2014, 2013 and 2012, respectively. The Company does not expect to make a contribution in 2015 other than possibly in conjunction with the termination of the Plan (discussed below).

In the first quarter 2014, the Company, based on the underfunded status of the Plan being only $10 at December 31, 2013, started the process of terminating the Plan, including requesting a determination letter from the Internal Revenue Service as to the qualified status of the Plan upon termination of the Plan. To that end, the administrative committee, consisting of management employees appointed by the Company's Board of Directors, consulted with the investment advisor for the Plan and reallocated the Plan's assets into stable assets consisting of cash and cash equivalents and short-term fixed income investments. The Company is not committed to terminate the Plan, and could decide not to do so. Prior to the reallocation of Plan assets, in consultation with the investment advisor, the administrative committee established the investment objectives for the Plan's assets, which were invested using a total return investment approach, whereby a mix of equity securities, debt securities, other investments and cash and cash equivalents were used to preserve asset values, diversify risk and achieve the target investment return benchmark. Investment strategies and asset allocations were based on careful consideration of Plan liabilities and the Plan's funded status and financial condition. Investment performance and asset allocation are measured and monitored on an ongoing basis.

The following table sets forth the asset allocation at December 31 for the Plan:
