Investments Carried at Fair Value
6.Investments Carried at Fair Value

Investments include $2.8 million and $2.7 million of investments carried at fair value as of June 30, 2016 and December 31, 2015, respectively, consisting of equity, bond and money market mutual funds.  Investments carried at fair value were acquired under a rabbi trust arrangement related to the Company’s nonqualified Supplemental Executive Retirement Plan (the “SERP”). The Company purchases investments in the trust to mirror the investment elections of participants in the SERP; gains and losses on the investments in the trust are reflected as increases or decreases in the liability owed to the participants. During the six months ended June 30, 2016, the Company recognized $153 thousand in dividend and interest income from investments, and recorded net unrealized gains of $83 thousand on these investments. Fair values for these investments held under the rabbi trust were determined by Level 1 quoted market prices for the underlying mutual funds.
