"(2) TREATMENT OF PROGRESS EXPENDITURES.—No progress expenditures for periods after December 31, 1985, with respect to any property shall be taken into account for purposes of applying the regular percentage unless it is reasonable to expect that such property will be transition property when placed in service. If any progress expenditures are taken into account by reason of the preceding sentence and subsequently there is not a reasonable expectation that such property would be transition property when placed in service, the credits attributable to progress expenditures with respect to such property shall be recaptured under section 47." (b) NORMALIZATION RULES.—If, for any taxable year beginning after December 31, 1985, the requirements of paragraph (1) or (2) of section 46(f) of the Internal Revenue Code of 1986 are not met with respect to public utility property to which the regular percentage applied for purposes of determining the amount of the investment tax credit— (1) all credits for open taxable years as of the time of the final determination referred to in section 46(f)(4)(A) of such Code shall be recaptured, and (2) if the amount of the taxpayer's unamortized credits (or the credits not previously restored to rate base) with respect to such property (whether or not for open years) exceeds the amount referred to in paragraph (1), the taxpayer's tax for the taxable year shall be increased by the amount of such excess. If any portion of the excess described in paragraph (2) is attributable to a credit which is allowable as a carryover to a taxable year beginning after December 31, 1985, in lieu of applying paragraph (2) with respect to such portion, the amount of such carryover shall be reduced by the amount of such portion. Rules similar to the rules of this subsection shall apply in the case of any property with respect to which the requirements of section 46(0(9) of such Code are met.
