This bill amends the Internal Revenue Code to exclude certain purchases of employee-owned stock from being considered as outstanding voting stock for the purpose of the tax on excess business holdings of a private foundation in a business enterprise. The bill applies to any voting stock that is (1) not readily tradable on an established securities market; (2) purchased by the business enterprise on or after January 1, 2005, from an employee stock ownership plan in which employees of the business enterprise participate, in connection with a distribution from the plan; and (3) held by the business enterprise as treasury stock, cancelled, or retired.
