Example 1. A, an individual, holds 25 percent by value of each class of stock of Y Corporation. Persons unrelated to A hold the remaining stock. Y holds 50 percent of the stock of Corporation X. Under paragraph (a)(2) of this section, Y's interests in X are attributed proportionately to the shareholders of Y. Accordingly, A is considered to hold a 12.5 percent (25 percent * 50 percent) interest in X.
Example 2. Z Bank's authorized capital consists of 100 shares of common stock and 100 shares of preferred stock. A holds 60 shares of each (common and preferred) and A's child, B, holds 40 shares of common stock. Z holds the balance of its own preferred stock, 30 shares as part of a common trust fund it maintains and 10 shares permanently set aside to satisfy a deferred obligation. For purposes of section 2701, A holds 60 shares of common stock and 66 shares of preferred stock in Z, 60 shares of each class directly and 6 shares of preferred stock indirectly (60 percent of the 10 shares set aside to fund the deferred obligation).
Example 3. An irrevocable trust holds a 10-percent general partnership interest in Partnership Q. One-half of the trust income is required to be distributed to O Charity. The other one-half of the income is to be distributed to D during D's life and thereafter to E for such time as E survives D. D holds one-half of the trust's interest in Q by reason of D's present right to receive one-half of the trust's income, and E holds one-half of the trust's interest in Q by reason of E's future right to receive one-half of the trust's income. Nevertheless, no family member is treated as holding more than one-half of the trust's interest in Q because at no time will either D or E actually hold, in the aggregate, any right with respect to income or corpus greater than one-half.
Example 4. An irrevocable trust holds a 10-percent general partnership interest in partnership M. One-half of the trust income is to be paid to D for D's life. The remaining income may, in the trustee's discretion, be accumulated or paid to or for the benefit of a class that includes D's child F, in such amounts as the trustee determines. On the death of the survivor of D and F, the trust corpus is required to be distributed to O Charity. The trust's interest in M is held by the trust's beneficiaries to the extent that present and future income or corpus may be distributed to them. Accordingly, D holds one-half of the trust's interest in M because D is entitled to receive one-half of the trust income currently. F holds the entire value of the interest because F is a member of the class eligible to receive the entire trust income for such time as F survives D. See paragraph (a)(5) of this section for rules applicable in the case of multiple attribution.
Example 5. The facts are the same as in Example 4, except that all the income is required to be paid to O Charity for the trust's initial year. The result is the same as in Example 4.
