§ 1.382-2. General rules for ownership change.

¶(i) In general. The term loss corporation means a corporation which—

¶(ii) Distributor or transferor loss corporation in a transaction under section 381. Notwithstanding that a loss corporation ceases to exist under state law, if its disallowed business interest expense carryforwards, net operating loss carryforwards, excess foreign taxes, or other items described in section 381(c) are succeeded to and taken into account by an acquiring corporation in a transaction described in section 381(a), such loss corporation will be treated as continuing in existence until—

¶(iii) Separate accounting required for losses and credits of an acquiring corporation and a distributor or transferor loss corporation. Except as provided in paragraph (a)(1)(iv) of this section, pre-change losses (determined as if the testing date were the change date and treating the amount of any net unrealized built-in loss as a pre-change loss), that are succeeded to and taken into account by an acquiring corporation in a transaction to which section 381(a) applies must be accounted for separately from losses and credits of the acquiring corporation for purposes of applying this section. See Example (2) of § 1.382-2T(e)(2)(iv) of this section.

¶(iv) End of separate accounting for losses and credits of distributor or transferor loss corporation. The separate tracking of owner shifts of the stock of an acquiring corporation required by paragraph (a)(1)(iii) of this section with respect to the net operating loss carryovers and other attributes described in paragraph (a)(1)(ii) of this section ends when a fold-in event occurs. A fold-in event is either an ownership change of the distributor or transferor corporation in connection with, or after, the transaction to which section 381(a) applies, or a period of 5 consecutive years following the section 381(a) transaction during which the distributor or transferor corporation has not had an ownership change. Starting on the day after the earlier of the change date (but not earlier than the day of the section 381(a) transaction) or the last day of the 5 consecutive year period, the losses and other attributes of the distributor or transferor corporation are treated as losses and attributes of the acquiring corporation for purposes of determining whether an ownership change occurs with respect to such losses. Also, for purposes of determining the beginning of the acquiring corporation's testing period, such losses are considered to arise either in a taxable year that begins not earlier than the later of the day following the change date or the day of the section 381(a) transaction, or in a taxable year that begins 3 years before the end of the 5 consecutive year period. Pre-change losses of a distributor or transferor corporation that are subject to a limitation under section 382 continue to be subject to the limitation notwithstanding the occurrence of a fold-in event. Any ownership change that occurs in connection with, or subsequent to, the section 381 transaction may result in an additional, lesser limitation with respect to such pre-change losses.

¶(v) Application to other successor corporations. This paragraph (a)(1) also applies, as the context may require, to successor corporations other than successors in section 381(a) transactions. For example, if a corporation receives assets from the loss corporation that have basis in excess of value, the recipient corporation's basis for the assets is determined, directly or indirectly, in whole or in part, by reference to the loss corporation's basis, and the amount by which basis exceeds value is material, the recipient corporation is a successor corporation subject to this paragraph (a)(1).

¶(i) Any net operating loss carryforward of the old loss corporation to the taxable year ending on the change date or in which the change date occurs;

¶(ii) Any net operating loss of the old loss corporation for the taxable year in which the ownership change occurs to the extent such loss is allocable to the period in such year on or before the change date;

¶(iii) Any recognized built-in loss for any recognition period taxable year (within the meaning of 382(h));

¶(iv) Any pre-change capital losses described in § 1.383-1T(c)(2)(i) and (ii);

¶(v) Any pre-change credits described in 1.383-1T(c)(3); and

¶(vi) Any section 382 disallowed business interest carryforward.

¶(i) In general. Except as provided in this paragraph (a)(3)(i) and § 1.382-2T(f)(18)(ii) and (iii), the term stock means stock other than stock described in section 1504(a)(4). Notwithstanding the preceding sentence, stock that is not described in section 1504(a)(4) solely because it is entitled to vote as a result of dividend arrearages shall be treated as so described and thus shall not be considered stock. Stock described in section 1504(a)(4), however, is not excluded for purposes of determining the value of the loss corporation under section 382(e). The determination of the percentage of stock of any corporation owned by any person shall be made on the basis of the relative fair market value of the stock owned by such person to the total fair market value of the outstanding stock of the corporation. Solely for purposes of determining the percentage of stock owned by a person, each share of all the outstanding shares of stock that have the same material terms is treated as having the same value. Thus, for example, a control premium or blockage discount is disregarded in determining the percentage of stock owned by any person.

¶(ii) Convertible stock. The term stock includes any convertible stock. For rules regarding the treatment of certain convertible stock as an option, see § 1.382-4(d)(9)(ii).

¶(i) In general. Except as provided in paragraph (a)(4)(ii) of this section, a loss corporation is required to determine whether an ownership change has occurred immediately after any owner shift, or issuance or transfer (including an issuance or transfer described in § 1.382-4(d)(8)(i) or (ii)) of an option with respect to stock of the loss corporation that is treated as exercised under § 1.382-4(d)(2). Each date on which a loss corporation is required to make a determination of whether an ownership change has occurred is referred to as a testing date. All computations of increases in percentage ownership are to be made as of the close of the testing date and any transactions described in this paragraph (a)(4) that occur on that date are treated as occurring simultaneously at the close of the testing date. See § 1.382-2T(e)(1) for the definition of owner shift. The term option, as used in this paragraph (a)(4), includes interests that are treated as options under § 1.382-4(d)(9).

¶(ii) Exceptions. A loss corporation is not required to determine whether an ownership change has occurred immediately after—

¶(i) The loss corporation's disallowed business interest expense carryforwards (as defined in § 1.163(j)-1(b)(11)), including disallowed disqualified interest (as defined in § 1.163(j)-1(b)(12)), as of the date of the ownership change.

¶(ii) The loss corporation's current-year business interest expense (as defined in § 1.163(j)-1(b)(9)) in the change year (as defined in § 1.382-6(g)(1)) that is allocable to the pre-change period (as defined in § 1.382-6(g)(2)) under § 1.382-6(a) or (b) and that becomes disallowed business interest expense (as defined in § 1.163(j)-1(b)(10)).

¶(i) In general. Except as provided in paragraph (b)(2)(ii) of this section, the rules provided in paragraph (a)(3)(ii) of this section apply with respect to any convertible stock.

¶(ii) Certain convertible preferred stock. Convertible stock that, when issued, would be described in section 1504(a)(4) by disregarding subparagraph (D) thereof and by ignoring the potential participation in corporate growth that the conversion feature may offer is treated as stock described in that section (and thus is not treated as stock for the purpose of determining whether an ownership change occurs, but is taken into account for the purpose of determining the value of the loss corporation immediately before an ownership change; see sections 382(e)(1) and 382(k)(6)(A)) if—
