Debt Disclosure [Abstract] |
Convertible Notes Payable | Convertible Notes Payable In December 2006 and January 2007, the Company issued a total of $115.0 million of convertible notes with a fixed interest rate of 3.75% due 2026 (the "Convertible Notes"). 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 are unsecured, unsubordinated obligations and rank 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. The additional non-cash interest expense recognized in the Consolidated Statements of Income was $0.8 million for the year ended December 31, 2011. As of December 31, 2013, $114.6 million of the Convertible Notes have been repurchased. The remaining Convertible Notes bear interest at 3.75% and the Company has the right to redeem the notes, in whole, or in part, at any time, and from time to time, for cash equal to 100% of the principal amount of the notes plus any accrued and unpaid interest to, but not including, the redemption date. The Holders of notes may require the Company to repurchase their notes, in whole or in part, on December 15, 2016 and December 15, 2021 for cash equal to 100% of the principal amount of the notes to be repurchased plus any accrued and unpaid interest to, but not including, the repurchase date.
