Example. USCo, a domestic corporation, and FCo, a foreign corporation, are publicly traded companies, each having two classes of stock outstanding. USCo's class A shares, which constitute 75% of the value of all beneficial ownership in USCo, are stapled to FCo's class B shares, which constitute 25% of the value of all beneficial ownership in F Co. USCo's class B shares, which constitute 25% of the value of all beneficial ownership in USCo, are stapled to FCo class A shares, which constitute 75% of the value of all beneficial ownership in FCo. Because more than 50% of the aggregate value of the stock of each corporation is stapled to the stock of the other corporation, USCo and FCo are stapled entities within the meaning of section 269B(c)(2).
Example. FCo, a Country X corporation, is a stapled foreign corporation that is treated as a domestic corporation under section 269B. FCo qualifies as a resident of Country X pursuant to the income tax treaty between the United States and Country X. Under such treaty, the United States is permitted to tax business profits of a Country X resident only to the extent that the business profits are attributable to a permanent establishment of the Country X resident in the United States. While FCo earns income from sources within and without the United States, it does not have a permanent establishment in the United States within the meaning of the relevant treaty. Under paragraph (e)(1) of this section, however, FCo is subject to U.S. Federal income tax on its income as a domestic corporation without regard to the provisions of the U.S.-Country X treaty and therefore without regard to the fact that FCo has no permanent establishment in the United States.
