then no deduction shall be allowed for such payment. The basis of the stock used to close the short sale shall be increased by the amount not allowed as a deduction by reason of the preceding sentence.

(2) Longer period in case of extraordinary dividends

If the payment described in paragraph (1)(A) is in respect of an extraordinary dividend, paragraph (1)(B) shall be applied by substituting "the day 1 year after the date of such short sale" for "the 45th day after the date of such short sale".

(3) Extraordinary dividend

For purposes of this subsection, the term "extraordinary dividend" has the meaning given to such term by section 1059(c); except that such section shall be applied by treating the amount realized by the taxpayer in the short sale as his adjusted basis in the stock.

(4) Special rule where risk of loss diminished

The running of any period of time applicable under paragraph (1)(B) (as modified by paragraph (2)) shall be suspended during any period in which-

(A) the taxpayer holds, has an option to buy, or is under a contractual obligation to buy, substantially identical stock or securities, or

(5) Deduction allowable to extent of ordinary income from amounts paid by lending broker for use of collateral

(2) such costs shall-
