The diversified investments held in the trusts totaled $21.4 million and $19.1 million as of September 30, 2017 and December 31, 2016, respectively, and are recorded at their fair value, based on quoted market prices. At September 30, 2017, the Company expects $1.6 million of the assets held in the trust to be distributed during the next twelve months to participants. These investments are considered trading securities and therefore the changes in the fair value of the diversified assets are included in other gains and losses in the accompanying consolidated statements of income. The Company recorded investment gains during the three months ended September 30, 2017 and 2016 of approximately $0.8 million and $0.8 million, respectively. The Company recorded investment gains during the nine months ended September 30, 2017 and 2016 of approximately $2.2 million and $1.0 million, respectively.

Non-Qualified Retirement, Savings and Investment Plans

The Company sponsors two non-qualified retirement savings and investment plans for certain employees and senior executives. Employee and Company contributions are maintained in separate irrevocable trusts. Legally, the assets of the trusts remain those of the Company; however, access to the trusts’ assets is severely restricted. The trusts cannot be revoked by the Company or an acquirer, but the assets are subject to the claims of the Company’s general creditors. The participants do not have the right to assign or transfer contractual rights in the trusts.

In 2002, the Company adopted the Choice Hotels International, Inc. Executive Deferred Compensation Plan ("EDCP"), which became effective January 1, 2003. Under the EDCP, certain executive officers may defer a portion of their salary into an irrevocable trust and invest these amounts in a selection of available diversified investment options. In 1997, the Company adopted the Choice Hotels International, Inc. Non-Qualified Retirement Savings and Investment Plan ("Non-Qualified Plan"). The Non-Qualified Plan allows certain employees who do not participate in the EDCP to defer a portion of their salary and invest these amounts in a selection of available diversified investment options. Under the EDCP and Non-Qualified Plan, (together, the "Deferred Compensation Plan"), the Company recorded current and long-term deferred compensation liabilities of $26.0 million and $24.7 million at September 30, 2017 and December 31, 2016, respectively, related to these deferrals and credited investment returns under these two deferred compensation plans.
