Crocs said it completed on Aug. 10 the issuance and sale of $350 million worth of senior notes carrying annual interest of 4.125 percent and due to mature on Aug. 15, 2031. They will be used for share buybacks and general corporate purposes. The notes were purchased by several institutional investors represented and guaranteed by Morgan Stanley & Co. Combined with the $350 million in senior notes already issued by Crocs in 2019, they will raise the company’s financial leverage to about 1.6 times. Moody’s and Standard & Poor’s both assigned the same ratings as in 2019 to the new debt, while confirming their ratings for the company’s existing debt.
