U.S. disposition loss
(44) The term U.S. disposition loss means the amount of loss recognized for U.S. income tax purposes on a disposition of an RFA, regardless of whether the loss is deferred or disallowed or otherwise not taken into account currently. Notwithstanding the foregoing, if after a section 743(b) CAA there is a disposition of an asset that is an RFA with respect to that section 743(b) CAA, U.S. disposition loss has the meaning provided in 1.901(m)-5T(c)(2)(iii).
