Atlas America, Inc. (NASDAQ:ATLS) ("the Company”) reported today that it has filed its June 30, 2007 Form 10-Q with the Securities and Exchange Commission. The Company did not adjust its earnings for the three and six months ended June 30, 2007 as anticipated in its August 9, 2007 press release. The Company also announced that it has filed an amended Form 10-K for the year ended December 31, 2006 with the Securities and Exchange Commission. This Form 10-K/A reflects a non-cash adjustment to the Company’s December 31, 2006 financial statements that increases net income by $29.8 million to $45.8 million for the year ended December 31, 2006. The adjustment is the result of the Company’s evaluation of the application of Staff Accounting Bulletin No. 51, "Accounting by the Parent in Consolidation for Sales of Stock by a Subsidiary”, ("SAB No. 51") with regard to equity transactions of its subsidiaries in prior years. The Company had previously concluded that SAB No. 51 did not apply to pass-through subsidiary entities. Upon further review, the Company has concluded that these equity transactions should be accounted for under the provisions of SAB No. 51.
