Example.
Corporation A is organized under the laws of a foreign state and is wholly owned and controlled by a foreign national. With a view towards avoiding possible application of section 721, Corporation A transfers money to a U.S. citizen, who, pursuant to informal arrangements with Corporation A and on its behalf, purchases all the shares in Corporation X, a U.S. business. That transaction is subject to section 721.
