(b) any person or partnership that was a member of the partnership immediately before that time may deduct, for a taxation year ending at or after that time, that proportion of the amount that would, but for this section, have been deductible under section 176 by the partnership in the fiscal period ending in the year had it continued to exist and had the partnership interest not been redeemed, acquired or cancelled, that the fair market value of such member’s interest in the partnership immediately before that time is of the fair market value of all the interests in the partnership immediately before that time.
