Debt Disclosure [Abstract] |
Debt | Debt Senior Bank Debt The Company has a $1.25 billion senior unsecured revolving credit facility (the "credit facility") which matures in April 2018. As of March 31, 2014, the current outstanding balance under the credit facility was $400.0 million. On April 15, 2014, the Company entered into a $250.0 million five-year senior unsecured term loan. The Company pays interest at specified rates (based either on the LIBOR rate or the prime rate as in effect from time to time). Subject to certain conditions, the Company may borrow up to an additional $100.0 million. The credit facility and term loan contain financial covenants with respect to leverage and interest coverage, as well as customary affirmative and negative covenants, including limitations on priority indebtedness, liens, cash dividends, asset dispositions, and fundamental corporate changes, and certain customary events of default. Senior Notes On February 11, 2014, the Company sold $400.0 million aggregate principal amount of 4.25% senior notes due 2024 (the “2024 senior notes”). The unsecured 2024 senior notes pay interest semi-annually and may be redeemed at any time, in whole or in part, at a make-whole redemption price plus accrued and unpaid interest. In addition to customary event of default provisions, the underlying indenture limits the Company's ability to consolidate, merge or sell all or substantially all of its assets, and to create certain liens. Convertible Securities On February 13, 2014, the Company delivered a notice to redeem all of its outstanding 2006 junior convertible trust preferred securities. In lieu of redemption, substantially all holders of the 2006 junior convertible trust preferred securities elected to convert their securities into a defined number of shares. The Company issued 1.9 million shares of its common stock in connection with the conversion. As of March 31, 2014, all of the Company's 2006 junior convertible trust preferred securities have been canceled and retired. The Company recognized an expense of $18.8 million upon redemption, which is included in Imputed interest expense and contingent payment arrangements.
