The classifications of debt and equity securities are determined by the Company at the date individual investments are acquired. The appropriateness of such classification is periodically reassessed. The Company monitors the fair value of all investments, and based on factors such as market conditions, financial information and industry conditions, the Company reflects impairments in values when warranted. The classification of those securities and the related accounting policies are as follows: Investments Carried at Fair Value: Investments in equity and bond mutual funds and investment trusts held within the Company’s rabbi trust, which is related to the Company’s unfunded Supplemental Executive Retirement Plan, ("SERP"), are reported at fair value using net asset value per share. The Company has elected to recognize unrealized gains and losses on investments carried at fair value in earnings, pursuant to the fair value option in ASC 820, Fair Value Measurement. Investments carried at fair value were acquired under a rabbi trust arrangement related to the Company’s SERP. The Company purchases investments in the trust to mirror the investment elections of participants in the SERP. The Company recorded a loss of $0.2 million, gain of $0.5 million and gain of $0.1 million in 2018, 2017 and 2016, respectively. Fair values for these investments are determined by quoted market prices for the underlying mutual funds, which may be based upon net asset value. Gains and losses on the investments in the trust are reflected as increases or decreases in the liability owed to the participants and are recorded as pension expense included within "Non-operating income (loss), net" in our consolidated statements of operations. Investments Carried at Cost: Investments in common stock in which the Company does not have a significant ownership (less than 20%) and for which there is no ready market, are carried at cost. Information regarding investments carried at cost is reviewed for evidence of impairment. Impairments, if any, are charged to earnings and a new cost basis for the investment is established. The Company’s investment in CoBank increased $0.9 million and $0.7 million in the years ended December 31, 2018 and 2017, respectively, due to the ongoing equity-based patronage earned from the outstanding investment and loan balances the Company has with CoBank. Equity Method Investments: Investments in the equity of partnerships and in unconsolidated corporations where the Company's ownership is 20% or more, but less than 50%, or where the Company otherwise has the ability to exercise significant influence, are reported under the equity method. Under this method, the Company's equity in earnings or losses of investees is reflected in earnings. Distributions received reduce the carrying value of these investments. The Company recognizes a loss when there is a decline in value of the investment which is other than a temporary decline. At December 31, 2018, the Company had a 23% ownership interest in Virginia Independent Telephone Alliance and a 20% ownership interest in Valley Network Partnership.
