Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Fair Value of Financial Instruments. The fair values of receivables and short-term borrowings approximate their carrying values due to the short-term nature of the instruments. The Company’s cash and cash equivalents, consisting principally of cash on deposit, may from time to time include short-term money markets funds. The fair values of these money market funds, based on market prices (level 2), approximate their carrying values due to their short-maturities. The carrying amount and fair value of the Company’s long-term debt at June 30, 2015 was $617.4 million and $632.0 million, respectively, and $706.0 million and $729.6 million at December 31, 2014, respectively. The fair value of long-term debt is calculated by discounting the future cash flows of the debt at rates based on instruments with similar risk, terms and maturities as compared to the Company’s existing debt arrangements (level 2).
