Example. X is a charitable remainder annuity trust described in section 664(d)(1) that was created after December 10, 1998. The prorated annuity amount payable from X for Year 1 is $100. The trustee does not pay the annuity amount to the recipient by the close of Year 1. At the end of Year 1, X has only $95 in the ordinary income category under section 664(b)(1) and no income in the capital gain or tax-exempt income categories under section 664(b)(2) or (3), respectively. By April 15 of Year 2, in addition to $95 in cash, the trustee distributes to the recipient of the annuity a capital asset with a $5 fair market value and a $2 adjusted basis to pay the $100 annuity amount due for Year 1. The trust owned the asset at the end of Year 1. Under § 1.664-1(d)(5) , the distribution is treated as a sale by X, resulting in X recognizing a $3 capital gain. The trustee elects to treat the capital gain as occurring on the last day of Year 1. Under § 1.664-1(d)(1) , the character of the annuity amount for Year 1 in the recipient's hands is $95 of ordinary income, $3 of capital gain income, and $2 of trust corpus. For Year 1, X satisfied paragraph (a)(1)(i)(a) of this section.
Example. The will of X provides for the transfer of one-half of his residuary estate to a charitable remainder annuity trust which is required to pay to W for life an annuity equal to 5 percent of the initial net fair market value of the interest passing in trust as finally determined for Federal tax purposes. The annuity is to be paid on December 31 of each year computed from the date of X's death. The will also provides that if such initial net fair market value is incorrectly determined, the trust shall pay to W, in the case of an undervaluation, or be repaid by W, in the case of an overvaluation, an amount equal to the difference between the amount which the trust should have paid if the correct value were used and the amount which the trust actually paid. X dies on March 1, 1971. The executor files an estate tax return showing the value of the residuary estate as $250,000 before reduction for taxes and expenses of $50,000. The executor paid to W $4,192 ([$250,000 - $50,000] * 1/2 * 5 percent * 306/365) on December 31, 1971. On January 1, 1972, the executor transfers one-half of the residue of the estate to the trust. The trust adopts the calendar year as its taxable year. The value of the residuary estate is finally determined for Federal tax purposes to be $240,000 ($290,000 - $50,000). Accordingly, the amount which the executor should have paid to W is $5,030 ([$290,000 - $50,000] * 1/2 * 5 percent * 306 / 365). Consequently, an additional amount of $838 ($5,030 - $4,192) must be paid to W within a reasonable period after the final determination of value for Federal tax purposes.
