In general
For purposes of this chapter, if property which has been used predominantly without the United States in a trade or business is disposed of during any taxable year—
(i)#
the taxpayer, notwithstanding any other provision of this chapter (other than paragraph (1)), shall be deemed to have received and recognized taxable income from sources without the United States in the taxable year of the disposition, by reason of such disposition, in an amount equal to the lesser of the excess of the fair market value of such property over the taxpayer’s adjusted basis in such property or the remaining amount of the overall foreign losses which were not used under paragraph (1) for such taxable year or any prior taxable year, and
(ii)#
paragraph (1) shall be applied with respect to such income by substituting “100 percent” for “50 percent”.
In determining for purposes of this subparagraph whether the predominant use of any property has been without the United States, there shall be taken into account use during the 3-year period ending on the date of the disposition (or, if shorter, the period during which the property has been used in the trade or business).
