In determining the tax under this chapter of any holder of a residual interest in a REMIC, such holder shall take into account his daily portion of the taxable income or net loss of such REMIC for each day during the taxable year on which such holder held such interest.
The basis of any person’s residual interest in a REMIC shall be increased by the amount of the taxable income of such REMIC taken into account under subsection (a) by such person with respect to such interest.
Any amount taken into account under subsection (a) by any holder of a residual interest in a REMIC shall be treated as ordinary income or ordinary loss, as the case may be.
The amount of the net loss of any REMIC taken into account by a holder under subsection (a) with respect to any calendar quarter shall not exceed the adjusted basis of such holder’s residual interest in such REMIC as of the close of such calendar quarter (determined without regard to the adjustment under subsection (d)(2)(B) for such calendar quarter).
Any loss disallowed by reason of subparagraph (A) shall be treated as incurred by the REMIC in the succeeding calendar quarter with respect to such holder.
