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 nine months ended September 30, 2016, the Company recognized $161 thousand in dividend and interest income from investments, and recorded net unrealized gains of $180 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.
