26 U.S. Code § 473 - Qualified liquidations of LIFO inventories
The term “qualified inventory interruption” means a regulation, request, or interruption described in subparagraph (B) but only to the extent provided in the notice published pursuant to subparagraph (B).
The term “liquidation year” means the taxable year in which occurs the qualified liquidation to which this section applies.
The term “replacement year” means any taxable year in the replacement period; except that such term shall not include any taxable year after the taxable year in which replacement of the liquidated goods is completed.
The term “LIFO method” means the method of inventorying goods described in section 472.
An election under subsection (a) shall be made subject to such conditions, and in such manner and form and at such time, as the Secretary may prescribe by regulation.
If the closing inventory of the taxpayer for any replacement year reflects an increase over the opening inventory of such goods for such year, the goods reflecting such increase shall be considered, in the order of their acquisition, as having been acquired in replacement of the goods most recently liquidated (whether or not in a qualified liquidation) and not previously replaced.
In the case of any qualified liquidation, any goods considered under paragraph (1) as having been acquired in replacement of the goods liquidated in such liquidation shall be taken into purchases and included in the closing inventory of the taxpayer for the replacement year at the inventory cost basis of the goods replaced.
The Secretary shall prescribe such regulations as may be necessary to coordinate the provisions of this section with the provisions of section 472.
