The Deferred Plan is a non-qualified plan that allows participants to make tax-deferred contributions that cannot be made under the 401(k) Plan because of Internal Revenue Service limitations. Participants’ earnings on contributions made to the Deferred Plan fluctuate with the actual earnings and losses of a variety of available investment choices selected by the participant. Total liabilities under the Deferred Plan as of December 31, 2013 and 2012 were $13,397 and $10,037, respectively, and are included in other long-term liabilities in the consolidated balance sheet.

For the years ended December 31, 2013, 2012, and 2011, the Company made deferred compensation matches of $201, $213 and $179 respectively, to the Deferred Plan. Prior to the first quarter of 2012, the Deferred Plan was unfunded, with all earnings and losses recorded in general and administrative expenses in the consolidated statement of income and comprehensive income. The total expense recognized related to the unfunded portion of the Deferred Plan including the matching contributions was $487 and $20 for the years ended December 31, 2012, and 2011, respectively. During the first quarter of 2012, the Company elected to fund its deferred compensation obligations through a rabbi trust. The rabbi trust is subject to creditor claims in the event of insolvency, but the assets held in the rabbi trust are not available for general corporate purposes. Amounts in the rabbi trust are invested in mutual funds, as selected by participants, which are designated as trading securities and carried at fair value, and are included in other assets in the consolidated balance sheet. Fair value of mutual funds is measured using Level 1 inputs (quoted prices for identical assets in active markets), and the fair value of the investments in the rabbi trust was $13,397 and $10,037 as of December 31, 2013 and 2012, respectively. The Company records trading gains and losses in general and administrative expenses in the consolidated statement of income and comprehensive income, along with the offsetting amount related to the increase or decrease in deferred compensation to reflect its exposure of the Deferred Plan liability. The Company recorded $722 and $240 of unrealized gains on investments held in the rabbi trust during twelve months ended December 31, 2013 and 2012, respectively.
