This document contains final and temporary regulations addressing the treatment of certain income and assets related to the leasing of aircraft or vessels in foreign commerce under sections 367, 954, and 956 of the Internal Revenue Code (Code). The regulations reflect statutory changes made by section 415 of the American Jobs Creation Act of 2004 (AJCA).

The text of these temporary regulations also serves as the text of the proposed regulations set forth in the Proposed Rules section in this issue of the Federal Register.
