Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	15. Fair Value of Financial Instruments The carrying amounts reported at December 31, 2014 and 2015 for cash and cash equivalents, accounts receivable, prepaid expenses and other current assets, accounts payable and accrued liabilities approximate fair value because of the short-term maturity of these instruments and are categorized as Level 1 within the GAAP fair value hierarchy. The fair value of the Company’s revolving line of credit is categorized as Level 2. The carrying amount of the Company’s debt approximates fair value because interest rates approximate the current rates available to the Company. The Company has debt with variable and fixed interest rates. The fair value of debt with fixed interest rates was determined using the quoted market prices of debt instruments with similar terms and maturities, which are considered Level 2 inputs. The fair value of debt with variable interest rates was also measured using Level 2 inputs, including good faith estimates of the market value for the particular debt instrument, which represent the amount an independent market participant would provide, based upon market observations and other factors relevant under the circumstances. The carrying value of such debt approximated its estimated fair value at December 31, 2014 and 2015. The Company has entered into interest rate swap agreements to manage exposure to fluctuations in interest rates. Fair value of the interest rate swaps is determined using a pricing model based on published interest rates and other observable market data. The fair value was determined after considering the potential impact of collateralization, adjusted to reflect both the Company’s own nonperformance risk and the respective counterparty’s nonperformance risk. The fair value measurement of interest rate swaps utilizes Level 2 inputs. At each of December 31, 2014 and 2015, the fair value of the interest rate swaps represented a liability of $0.5 million. Refer to Note 9 for further discussion of the interest rate swap agreements. Intangible assets are measured at fair value on a non-recurring basis. These assets are classified in Level 3 of the fair value hierarchy. Goodwill and other indefinite-lived intangibles are tested for impairment at least annually, or more frequently if circumstances indicate that the carrying amount exceeds fair value. The Company estimates the fair values of goodwill and other indefinite-lived intangibles utilizing multiple measurement techniques. The estimation is primarily determined based on an estimate of future cash flows (income approach) discounted at a market derived weighted-average cost of capital. The income approach has been determined to be the most representative of fair value because the Company’s equity does not have an active trading market. Other unobservable inputs used in these valuations include management’s cash flow projections and estimated terminal growth rates. The valuation of indefinite-lived intangible assets also includes an unobservable input for royalty rate, which is based on rates used by comparable industries. The useful lives of definite-lived intangible assets (customer relationships) are evaluated whenever events or circumstances warrant a revision to the remaining amortization period. The fair value of definite-lived intangible assets is based on estimated cash flows from the future use of the asset, discounted at a market derived weighted-average cost of capital. No impairment charges were recorded related to goodwill or other intangible assets for the years ended December 31, 2013, 2014, and 2015. Long-lived assets are measured at fair value on a non-recurring basis and are classified in Level 3 of the fair value hierarchy. The fair value is estimated utilizing unobservable inputs, including appraisals on real estate as well as evaluations of the marketability and potential relocation of other assets in similar condition and similar market areas. The Company analyzes long-lived assets on an annual basis for any triggering events that would necessitate an impairment test. No impairment charges were recorded for the years ended December 31, 2013, 2014, and 2015.
