(6) Employee Retirement Plans

The Company has a noncontributory defined benefit pension plan (the "Corson 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 Corson Plan were frozen. During 1997 and 1998, the Company made contributions to the Corson Plan that were intended to fully fund the benefits earned by the participants. The unfunded projected benefit obligation is $10 and $290 at December 31, 2013 and 2012, respectively. The Company recorded comprehensive income of $197, net of $112 tax expense, $64, net of $36 tax expense and a comprehensive loss of $149, net of $85 tax benefit, for the years ended December 31, 2013, 2012 and 2011, respectively. The Company made contributions of $0, $151 and $18 to the Corson Plan in 2013, 2012 and 2011, respectively. The Company does not expect to make a contribution in 2014.

In consultation with the investment advisor for the Corson Plan, the administrative committee, consisting of management employees appointed by the Company's Board of Directors, establishes the investment objectives for the Plan's assets. The Plan's assets are invested using a total return investment approach, whereby a mix of equity securities, debt securities, other investments and cash and cash equivalents are used to preserve asset values, diversify risk and achieve the target investment return benchmark. Investment strategies and asset allocations are 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 Corson Plan's assets are managed in a balanced portfolio composed of two major components: an equity portion and a fixed income portion. The expected role of equity investments is to maximize the long-term real growth of the Plan's assets, while the role of fixed income investments is to generate current income, provide for more stable periodic returns and provide some protection against a prolonged decline in the market value of equity investments.

The current target allocations for Corson Plan assets are 50-70% for equity securities, 25-50% for fixed income securities, 0-15% for other investments and 0-10% for cash and cash equivalents. Equity securities include U.S. and international equity, while fixed income securities include short-duration government agencies and medium-duration bond funds and high-yield bond funds. Other investments include investments in a commodity linked fund and a real estate index fund. The following table sets forth the asset allocation at December 31 for the Plan:



Pooled equity funds	55.1	%	28.9	%
