Jun. 30, 2013

In May 2005, we issued $250.0 million aggregate principal amount of 3.625% convertible senior notes due 2025 (“3.625% convertible senior notes”), and in November 2005, we issued $300.0 million aggregate principal amount of 5.875% convertible senior notes due 2035 (“5.875% convertible senior notes”). These notes (net of repurchases since the issuance dates) are reflected within convertible senior notes on our consolidated balance sheets. In May 2012, substantially all of the holders of our 3.625% convertible senior notes exercised a then-existing put right, under which we repaid $83.5 million in face amount of such notes outstanding at par. No such put rights exist under our 5.875% convertible senior notes.
