Foresight Energy LP filed a shelf registration to sell up to $1 billion in total aggregate offering price of its securities.

The registration allows selling unit holders to offer and sell up to 43,846,217 common units. Selling unit holders include Christopher Cline, the Cline Trust Company LLC and the Cline Resource and Development Co. Together, those three entities own 52.9% of the outstanding common units as of Feb. 6. Each of the three is offering all or most of their units, according to the registration filed Feb. 12.

Foresight is an Illinois Basin coal producer in which Murray Energy Corp. owns a major stake. Murray Energy announced it was buying a stake in Foresight in early 2015 and has moved to acquire even more coal assets since.

The company, founded by Cline, completed its initial public offering on the NYSE in June 2014. Foresight will not receive any of the proceeds of sales made by the selling unit holders, which also include Murray South America Inc., Carvers Creek LLC and Hamilton Charterwood LLC.
