On July 16, 2012, the Company completed the redemption of the $436.7 million outstanding 5.25% Junior Convertible Subordinated Debentures (the “Debentures”). Because the 5.25% convertible preferred securities (the "Preferred Securities") were mandatorily redeemable upon the retirement of the Debentures, accordingly, the Preferred Securities were redeemed for cash of $421.2 million on July 16, 2012.
