CF Industries Holdings, Inc. (NYSE: CF) today announced that it has prepaid the $1.0 billion aggregate principal amount of its senior notes due 2022, 2025 and 2027, and paid the related make-whole amount of approximately $170 million. The make-whole amount was significantly less than the amount previously estimated (approximately $210 million as of October 31, 2016) as a result of subsequent changes in market interest rates. CF Industries made the prepayment and make-whole payment using the proceeds from its previously announced offering of $1,250,000,000 aggregate principal amount of senior secured notes comprising $500,000,000 aggregate principal amount of senior secured notes due 2021 and $750,000,000 aggregate principal amount of senior secured notes due 2026. The offering closed on November 21, 2016. In connection with the completion of the offering and the prepayment of the senior notes due 2022, 2025 and 2027, the previously announced amendments to the company's revolving credit facility became effective. The amendments include, among other things, changes in and additions to the financial covenants and a reduction in the size of the facility from $1.5 billion to $750 million. The senior secured notes have not been registered under the Securities Act of 1933, as amended (the "Securities Act"), or any state securities laws and, unless so registered, may not be offered or sold in the United States except pursuant to an exemption from, or in a transaction not subject to, the registration requirements of the Securities Act and applicable state securities laws.
