§ 1260. Gains from constructive ownership transactions
(a)
In general
If the taxpayer has gain from a constructive ownership transaction with respect to any financial asset and such gain would (without regard to this section) be treated as a long-term capital gain—
(1)
such gain shall be treated as ordinary income to the extent that such gain exceeds the net underlying long-term capital gain, and
(2)
to the extent such gain is treated as a long-term capital gain after the application of paragraph (1), the determination of the capital gain rate (or rates) applicable to such gain under section
1
(h) shall be determined on the basis of the respective rate (or rates) that would have been applicable to the net underlying long-term capital gain.
(b)
Interest charge on deferral of gain recognition
(1)
In general
If any gain is treated as ordinary income for any taxable year by reason of subsection (a)(1), the tax imposed by this chapter for such taxable year shall be increased by the amount of interest determined under paragraph (2) with respect to each prior taxable year during any portion of which the constructive ownership transaction was open. Any amount payable under this paragraph shall be taken into account in computing the amount of any deduction allowable to the taxpayer for interest paid or accrued during such taxable year.
(2)
Amount of interest
The amount of interest determined under this paragraph with respect to a prior taxable year is the amount of interest which would have been imposed under section
6601 on the underpayment of tax for such year which would have resulted if the gain (which is treated as ordinary income by reason of subsection (a)(1)) had been included in gross income in the taxable years in which it accrued (determined by treating the income as accruing at a constant rate equal to the applicable Federal rate as in effect on the day the transaction closed). The period during which such interest shall accrue shall end on the due date (without extensions) for the return of tax imposed by this chapter for the taxable year in which such transaction closed.

(e)
Net underlying long-term capital gain
For purposes of this section, in the case of any constructive ownership transaction with respect to any financial asset, the term “net underlying long-term capital gain” means the aggregate net capital gain that the taxpayer would have had if—
(1)
the financial asset had been acquired for fair market value on the date such transaction was opened and sold for fair market value on the date such transaction was closed, and
(2)
only gains and losses that would have resulted from the deemed ownership under paragraph (1) were taken into account.
The amount of the net underlying long-term capital gain with respect to any financial asset shall be treated as zero unless the amount thereof is established by clear and convincing evidence.
(f)
Special rule where taxpayer takes delivery
Except as provided in regulations prescribed by the Secretary, if a constructive ownership transaction is closed by reason of taking delivery, this section shall be applied as if the taxpayer had sold all the contracts, options, or other positions which are part of such transaction for fair market value on the closing date. The amount of gain recognized under the preceding sentence shall not exceed the amount of gain treated as ordinary income under subsection (a). Proper adjustments shall be made in the amount of any gain or loss subsequently realized for gain recognized and treated as ordinary income under this subsection.
(g)
