FAIR VALUE MEASUREMENTS [Abstract]
FAIR VALUE MEASUREMENTS	4. FAIR VALUE MEASUREMENTS Fair value is defined as an exit price, representing the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants based upon the best use of the asset or liability at the measurement date. Entities are required to use a fair value hierarchy which maximizes the use of observable inputs and minimizes the use of unobservable inputs when measuring fair value. There are three levels of inputs that may be used to measure fair value: Level 1 – Observable inputs such as quoted market prices in active markets; Level 2 – Inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3 – Unobservable inputs about which little or no market data exists, therefore requiring an entity to develop its own assumptions. As of December 31, 2017, the Company held certain financial assets that are measured at fair value on a recurring basis. These consisted of securities that are among the Company's investments in a rabbi trust which are intended to fund the Company's Supplemental Executive Retirement Plan ("SERP") obligations. The gross unrealized gains associated with the investment securities held in the rabbi trust were $0.2 million at December 31, 2017. Such unrealized gains are included, net of tax, in accumulated other comprehensive loss. During the nine months ended September 30, 2018, the Company sold its securities and realized a gain on sale of $0.2 million. The proceeds of $1.3 million were reinvested in other securities within the rabbi trust. As of September 30, 2018 and December 31, 2017, our securities primarily consisted of investments held in a rabbi trust of $1.3 million and $1.5 million, respectively, which were measured at fair value using quoted prices in active markets for identical assets (Level 1) inputs. The Company does not have any financial assets measured at fair value on a recurring basis categorized as Level 3, and there were no transfers in or out of Level 1, Level 2 or Level 3 during the nine months ended September 30, 2018 or September 30, 2017. Excluding the changes made in accordance with the Company’s adoption of ASU 2016-01, there were no changes to the Company's valuation techniques used to measure asset fair values on a recurring or nonrecurring basis during the nine months ended September 30, 2018. There were no financial assets accounted for at fair value on a nonrecurring basis as of September 30, 2018 or December 31, 2017. The Company has other financial instruments, such as cash and cash equivalents, accounts receivable, restricted cash, accounts payable, accrued expenses and notes payable, which are not measured at fair value on a recurring basis but are recorded at amounts that approximate fair value due to their liquid or short-term nature. The fair value of the Company's long-term debt is estimated using a discounted cash flow method based on interest rates that are currently available for debt issuances with similar terms and maturities. At September 30, 2018 and December 31, 2017, the estimated fair value of total debt was $116.9 million and $124.8 million, respectively, compared to a carrying amount of $114.8 million and $122.7 million, respectively. The Company did not have any other financial liabilities within the scope of the fair value disclosure requirements as of September 30, 2018. Nonfinancial assets and liabilities, such as goodwill, indefinite-lived intangible assets and long-lived assets, are accounted for at fair value on a nonrecurring basis. These items are tested for impairment upon the occurrence of a triggering event or in the case of goodwill, on at least an annual basis. There were no triggering events that occurred during the nine months ended September 30, 2018 that would warrant interim impairment testing.
