This distribution was made in the form of a tax free, pro rata distribution of all the remaining shares of SunCoke common stock owned by Sunoco in the form of a special dividend to Sunoco shareholders. Sunoco shareholders received 0.53046456 of a share of SunCoke common stock for every one share of Sunoco common stock held as of the January 5th 2012 record date. Sunoco will deliver cash in lieu of a fractional share of SunCoke common stock.

Mr Frederick A Henderson chairman & CEO of SunCoke Energy Inc said that "Today marks the completion of the planned separation of SunCoke Energy from Sunoco. As an independent, publicly owned company, we believe SunCoke has increased flexibility to pursue domestic and international growth strategies, meet the needs of our steelmaking customers and create opportunities for our employees and shareholders. We thank Sunoco's leadership team led by Lynn L. Elsenhans and the Sunoco Board of Directors for their support and for working to ensure that our company has a solid foundation from which to grow our business over the long term."
