CONVERTIBLE NOTES PAYABLE	12 Months Ended

Debt Disclosure [Abstract]
Convertible Notes Payable	Convertible Notes Payable As of December 31, 2015, all $115.0 million of the convertible notes issued by the Company in December 2006 and January 2007 with a fixed interest rate of 3.75% due 2026 (the "Convertible Notes") have been repurchased, including $0.4 million repurchased during 2015. The Convertible Notes were issued at par and require interest payments semi-annually in arrears on June 15 and December 15 of each year. The Convertible Notes were unsecured, unsubordinated obligations and ranked equally with all other unsecured and unsubordinated indebtedness. The Convertible Notes were accounted for under ASC Topic 470-20, “Debt with Conversion and Other Options,” which required the Company to allocate the proceeds from the issuance between a debt component and an equity component. The resulting discount on the debt component was amortized over the period the convertible debt was expected to be outstanding, which was December 11, 2006 to December 20, 2011, as additional non-cash interest expense. Until December 20, 2011, the Convertible Notes had an effective interest rate of 6.03% after giving effect to ASC Topic 470-20.
