Example. Throughout 1965 corporation M owns all the stock of corporations L-1, L-2, S-1, and S-2. M is a domestic mutual insurance company subject to tax under section 821 of the Code, L-1 and L-2 are domestic life insurance companies subject to tax under section 802 of the Code, and S-1 and S-2 are domestic corporations subject to tax under section 11 of the Code. Each corporation uses the calendar year as its taxable year. M makes a valid election under section 243(b)(2) for the affiliated group consisting of M, L-1, L-2, S-1, and S-2. If part II, subchapter B, chapter 6 of the Code were applied with respect to the 1965 taxable years of the corporations without regard to section 243(b)(6)(A), the following would result: S-1 and S-2 would be treated as component members of a controlled group of corporations on such date; L-1 and L-2 would be treated as component members of a separate controlled group on such date; and M would be treated as an excluded member. However, since section 243(b)(6)(A) requires that part II of subchapter B be applied without regard to section 1563(a)(4) and (b)(2)(D), for purposes of determining the surtax exemptions of M, L-1, L-2, S-1, and S-2 for their 1965 taxable years, such corporations are treated for purposes of such part II as component members of a single controlled group of corporations on December 31, 1965. Moreover, by reason of having made the election under section 243(b)(2), M, L-1, L-2, S-1, and S-2 cannot consent to multiple surtax exemption elections under section 1562 which would be effective for their 1965 taxable years. Thus, such corporations are limited to a single $25,000 surtax exemption for such taxable years (to be apportioned among such corporations in accordance with section 1561 and the regulations thereunder).
Example. An affiliated group is composed of four member corporations, W, X, Y, and Z. The sum of the accumulated earnings and profits (as of the close of the preceding taxable year ending December 31, 1975) plus the earnings and profits for the taxable year ending December 31, 1976 which are retained is $15,000, $75,000, $37,500, and $300,000 in the case of W, X, Y, and Z, respectively. The amounts determined under this subparagraph for W, X, Y, and Z are $15,000, $48,750, $37,500 and $48,750, respectively, computed as follows:
Component members | ||||
W | X | Y | Z | |
Earnings and profits | $15,000 | $75,000 | $37,500 | $300,000 |
Amount computed under subpar. (1) | 37,500 | 37,500 | 37,500 | 37,500 |
Excess | 22,500 | 0 | 0 | 0 |
Allocation of excess | 7,500 | 7,500 | 7,500 | |
New excess | 7,500 | |||
Reallocation of new excess | 3,750 | 3,750 | ||
Amount to be used for purposes of sec. 535(c) (2) and (3) | 15,000 | 48,750 | 37,500 | 48,750 |
An apportionment plan, once terminated, is no longer effective. Accordingly, unless a new apportionment plan is filed and consented to (or the section 243(b)(2) election is terminated) the amounts referred to in subparagraph (1) of this paragraph will be apportioned among the corporations which are members of the affiliated group on each day of their matching taxable years in accordance with the rules provided in paragraphs (d)(3)(i), (d)(3)(ii), (d)(4), and (d)(5)(i) of this section.
