(b) Reduction for failure to receive tax benefit The amount otherwise includible in gross income under subsection (a) in respect of any security shall be reduced by an amount equal to the amount (if any) of the loss described in subsection (a)(2) which did not result in a reduction of the taxpayer’s tax under this subtitle for any taxable year, determined under regulations prescribed by the Secretary. (c) Character of income For purposes of this subtitle— (1) Except as provided in paragraph (2), the amount included in gross income under this section shall be treated as ordinary income.

(d) Treatment under foreign expropriation loss recovery provisions This section shall not apply to any recovery of a foreign expropriation loss to which section 1351 applies.
