Debt Disclosure [Abstract] |
Long-term Debt | Long-Term Debt Senior Notes Maiden Holdings and its wholly owned subsidiary, Maiden Holdings North America, Ltd. ("Maiden NA"), both have an outstanding public debt offering of senior notes which were issued in 2016 and 2013, respectively, (the "Senior Notes"). The 2013 Senior Notes issuance made by Maiden NA is fully and unconditionally guaranteed by the Company. The Senior Notes are unsecured and unsubordinated obligation of the Company. On June 27, 2017, we fully redeemed all of the 2012 Senior Notes using a portion of the proceeds from the Preference Shares - Series D issuance (see related discussion in "Note 11. Shareholders' Equity"). The 2012 Senior Notes were redeemed at a redemption price equal to 100% of the principal amount of $100,000 plus accrued and unpaid interest on the principal amount being redeemed up to, but not including, the redemption date. As a result, the Company accelerated the amortization of the remaining 2012 Senior Note issuance cost of $2,809. The following table details the Company's Senior Notes issuances as of September 30, 2017 and December 31, 2016:
