        over the new-law benefit amount, by
            ``(ii) the applicable reduction factor.
    ``(C) For purposes of this paragraph, in the case of any individual 
described in subparagraph (A)--
            ``(i) The term `adjusted old-law benefit amount' means the

        benefits in the case of an individual who becomes eligible for 
        such benefits prior to 1989) or subsection (d) (in the case of

        determined under subclause (III).
            ``(II) The applicable base percentage determined under this 
        subclause is the percentage provided in the following table:

        multiplying 5/12 of 1 percent by the total number of months, 
        before the month in which the individual attains the age of 65, 
        for which an old-age insurance benefit is payable to such 
        individual.''.
