Example. H was absolute owner of a rental property and on July 1, 1950, transferred it to A by gift, reserving the income for a period of 20 years. On July 1, 1955, he created a trust to last for a period of 10 years. H was to receive the income from the trust and at the termination of the trust the trustee is to turn over to H's wife, W, property having a value of $100,000. The trustee has absolute discretion in deciding which properties in the corpus he shall turn over to W in satisfaction of the gift to her. The trustee received two items of property from H. Item (1) consisted of shares of corporate stock. Item (2) consisted of the right to receive the income from the rental property during the unexpired portion of the 20-year term. Assume that at the termination of the trust on July 1, 1965, the value of the right to the rental income for the then unexpired term of 5 years (item (2)) will be $30,000. Since item (2) is a nondeductible interest and the trustee can turn it over to W in partial satisfaction of her gift, only $70,000 of the $100,000 receivable by her on July 1, 1965, will be considered as property with respect to which a marital deduction is allowable. The present value on July 1, 1955, of the right to receive $70,000 at the end of 10 years is $49,624.33 as determined under § 25.2512-5A(c) . The value of the property qualifying for the marital deduction, therefore, is $49,624.33 and a marital deduction is allowed for one-half of that amount, or $24,812.17.
