(C) In a case where neither (a) nor (b) of this subdivision is applicable, if the trust fund, or a specified portion thereof, is invested exclusively in one particular type of security of the employer corporation, and if during the period the distributee participated in the plan none of such securities has been sold except for the purpose of paying benefits under the trust or for the purpose of enabling the trustee to obtain funds with which to exercise rights which have accrued to the trust, the cost or other basis to the trust of all securities distributed to such distributee shall be the total amount credited to the account of such distributee (or such portion thereof as was available for investment in such securities) reduced by the amount available for investment but uninvested on the date of distribution. If at the time of distribution to a particular distributee a portion of the amount credited to his account is forfeited, appropriate adjustment shall be made with respect thereto in determining the cost or other basis to the trust of the securities distributed.
(D) (1) In all other cases, there shall be used the average cost (or other basis) to the trust of all securities of the employer corporation of the type distributed to the distributee which the trust has on hand at the time of the distribution, or which the trust had on hand on a specified inventory date which date does not precede the date of distribution by more than twelve calendar months. If a distribution includes securities of the employer corporation of more than one type, the average cost (or other basis) to the trust of each type of security distributed shall be determined. The average cost to the trust of securities of the employer corporation on hand on a specified inventory date (or on hand at the time of distribution) shall be computed on the basis of their actual cost, considering the securities most recently purchased to be those on hand, or by means of a moving average calculated by subtracting from the total cost of securities on hand immediately preceding a particular sale or distribution an amount computed by multiplying the number of securities sold or distributed by the average cost of all securities on hand preceding such sale or distribution.
(2) These methods of computing average cost may be illustrated by the following examples:
Example 1.
A, a distributee who makes his income tax returns on the basis of a calendar year, receives on August 1, 1954, in a total distribution, to which paragraph (a)(6) of this section is applicable, ten shares of class D stock of the employer corporation. On July 1, 1954 (the specified inventory date of the trust), the trust had on hand 80 shares of class D stock. The average cost of the 10 shares distributed, on the basis of the actual cost method, is $100 computed as follows:
| Shares | Purchase date | Cost per share | Total cost |
|---|
| 20 | June 24, 1954 | $101 | $2,020 |
| 40 | Jan. 10, 1953 | 102 | 4,080 |
| 20 | Oct. 20, 1952 | 95 | 1,900 |
| 80 | | 8,000 |
Example 2.
B, a distributee who makes his income tax returns on the basis of a calendar year, receives on October 31, 1954, in a total distribution, to which paragraph (a)(6) of this section is applicable, 20 shares of class E stock of the employer corporation. The specified inventory date of the trust is the last day of each calendar year. The trust had on hand on December 31, 1952, 1,000 shares of class E stock of the employer corporation. During the calendar year 1953 the trust distributed to four distributees a total of 100 shares of such stock and acquired, through a number of purchases, a total of 120 shares. The average cost of the 20 shares distributed to B, on the basis of the moving average method, is $52 computed as follows:
| Shares | Total cost | Average cost |
|---|
| On hand Dec. 31, 1952 | 1,000 | $50,000 | $50 |
| Distributed during 1953 at average cost of $50 | 100 | 5,000 | (0) |
| 900 | 45,000 | (0) |
| Purchased during 1953 | 120 | 8,000 | (0) |
| On hand Dec. 31, 1953 | 1,020 | 53,040 | 52 |
(3) Unrealized appreciation attributable to employee contributions. In any case in which it is necessary to determine the amount of net unrealized appreciation in securities of the employer corporation which is attributable to contributions made by an employee:
(i) The cost or other basis of the securities to the trust and the amount of net unrealized appreciation shall first be determined in accordance with the regulations in subparagraph (2) of this paragraph;
(ii) The amount contributed by the employee to the purchase of the securities shall be solely the portion of his actual contributions to the trust properly allocable to such securities, and shall not include any part of the increment in the trust fund expended in the purchase of the securities;
(iii) The amount of net unrealized appreciation in the securities distributed which is attributable to the contributions of the employee shall be that proportion of the net unrealized appreciation determined under the regulations of subparagraph (2) of this paragraph which the contributions of the employee properly allocable to such securities bear to the cost or other basis to the trust of the securities;
(iv) If a distribution consists solely of securities of the employer corporation, the contributions of the employee expended in the purchase of such securities shall be allocated to the securities distributed in a manner consistent with the principles set forth in subparagraph (2)(ii) (a), (b), (c), or (d) of this paragraph, whichever is applicable. Thus, the amount of the employee's contribution which can be identified as having been expended in the purchase of a particular security shall be allocated to such security, and the amount of such contribution which cannot be so identified shall be allocated ratably among the securities distributed. If a distribution consists in part of securities of the employer corporation and in part of cash or other property, appropriate allocation of a portion of the employee's contribution to such cash or other property shall be made unless such a location is inconsistent with the terms of the plan or trust.
(v) The application of this subparagraph may be illustrated by the following example:
Example.
A trust distributes ten shares of stock issued by the employer corporation each of which has an average cost to the trust of $100, consisting of employee contributions in the amount of $60 and employer contributions in the amount of $40, and on the date of distribution has a fair market value of $180. The portion of the net unrealized appreciation attributable to the contributions of the employee with respect to each of the shares of stock is $48 computed as follows:
| (1) Value of one share of stock on distribution date | $180 |
| (2) Employee contributions | 60 |
| (3) Employer contributions | 40 |
| (4) Total contributions | 100 |
| (5) Net unrealized appreciation | 80 |
| (6) Portion of net unrealized appreciation attributable to employee contributions 60/100 (amount of employee contributions (item 2) over total contributions (item 4) of $80 (item 5) | 48 |
(vi) For the purpose of determining gain or loss to the distributee in the year or years in which any share of stock referred to in the example in subdivision (v) of this subparagraph is sold or otherwise disposed of in a taxable transaction, the basis of each such share in the hands of the distributee at the time of the distribution by the trust will be $132 computed as follows:
| (a) Employee contributions | $60 |
| (b) Employer contributions (taxable as ordinary income in the year the securities were distributed) | 40 |
| (c) Portion of net unrealized appreciation attributable to employer contributions (item 5) minus (item 6) (taxable as ordinary income in the year the securities were distributed) | 32 |
| (d) Basis of stock | 132 |
(4) Change in exempt status of trust. For principles applicable in making appropriate adjustments if the trust was not exempt for one or more years before the year of distribution, see paragraph (a) of this section.
