Item 2.01. Completion of Acquisition or Disposition of Assets.

We have previously reported that on August 28, 2013, we entered into a Purchase and Sale Agreement with IBEX Mineral Resources, LLC and Beehive Partners, LLC to purchase mineral rights underlying approximately 15,000 gross (12,500 net) acres in Midland County, Texas in the Permian Basin (the “Acquisition”). On September 19, 2013, we closed the Acquisition for a cash purchase price of $440.0 million. We funded the Acquisition with the net proceeds of our offering of 7.625% Senior Notes due 2021 to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”), and to certain non-U.S. persons in accordance with Regulation S under the Securities Act, which offering was completed on September 17, 2013. We are the operator of almost half of the acreage on which the mineral rights acquired by us in the Acquisition are located.

Item 9.01. Financial Statements and Exhibits.

To the extent it is determined that any financial statements or pro forma financial information with respect to the Acquisition is required by Item 9.01 of Form 8-K, such statements or information will be included in an amendment to this Form 8-K by not later than 71 calendar days after the date that the initial report on Form 8-K must be filed.
