    (a) In the case of the acquisition of assets of a corporation by another corporation described in Section 381(a) of the Internal Revenue Code, the acquiring corporation shall succeed to and take into account, as of the close of the day of distribution or transfer, all Article 2 credits and net losses under Section 207 of the corporation from which the assets were acquired.
    (b) In the case of the acquisition of assets of a partnership by another partnership in a transaction in which the acquiring partnership is considered to be a continuation of the partnership from which the assets were acquired under the provisions of Section 708 of the Internal Revenue Code and any regulations promulgated under that Section, the acquiring partnership shall succeed to and take into account, as of the close of the day of distribution or transfer, all Article 2 credits and net losses under Section 207 of the partnership from which the assets were acquired.
    (b-5) No limitation under Section 382 of the Internal Revenue Code or the separate return limitation year regulations promulgated under Section 1502 of the Internal Revenue Code shall apply to the carryover of any Article 2 credit or net loss allowable under Section 207.
    (c) The provisions of this amendatory Act of the 91st General Assembly shall apply to all acquisitions occurring in taxable years ending on or after December 31, 1986; provided that if a taxpayer's Illinois income tax liability for any taxable year, as assessed under Section 903 prior to January 1, 1999, was computed without taking into account all of the Article 2 credits and net losses under Section 207 as allowed by this Section:
        (1) no refund shall be payable to the taxpayer for that taxable year as the result of
    
allowing any portion of the Article 2 credits or net losses under Section 207 that were not taken into account in computing the tax assessed prior to January 1, 1999;
        (2) any deficiency which has not been paid may be reduced (but not below zero) by the
    
allowance of some or all of the Article 2 credits or net losses under Section 207 that were not taken into account in computing the tax assessed prior to January 1, 1999; and
        (3) in the case of any Article 2 credit or net loss under Section 207 that, pursuant to
    
this subsection (c), could not be taken into account either in computing the tax assessed prior to January 1, 1999 for a taxable year or in reducing a deficiency for that taxable year under paragraph (2) of subsection (c), the allowance of such credit or loss in any other taxable year shall not be denied on the grounds that such credit or loss should properly have been claimed in that taxable year under subsection (a) or (b).
