Subsequent Event

On February 7, 2018, we announced that TNGP, the sole general partner of TNCLP and an indirect wholly owned subsidiary of CF Holdings, elected to exercise its right to purchase all of the 4,612,562 publicly traded common units of TNCLP on April 2, 2018, for a cash purchase price of $84.033 per unit in accordance with the terms of TNCLP’s partnership agreement. The purchase price of $84.033 per unit was determined under the terms of TNCLP’s partnership agreement as the average of the daily closing prices per common unit for the 20 consecutive trading days beginning with January 5, 2018 and ending with February 2, 2018. The purchase price of all of the 4,612,562 publicly traded common units of TNCLP is approximately $390 million. We intend to fund the purchase with cash on hand. As of the April 2, 2018 purchase date, all rights of the holders of the units will terminate, with the exception of the right to receive payment of the purchase price. Upon completion of the purchase, we will own 100 percent of the general and limited partnership interests of TNCLP, and the common units representing limited partner interests will cease to be publicly traded or listed on the NYSE.
