Capital gain reinvestment: exemption for gains invested in eligible public equity, recaptured if shares disposed within minimum holding period. Capital gains from transfer of long term listed securities or units are not charged to tax to the extent the assessee reinvests the gain within six months in acquiring specified equity shares of an eligible public issue; exemption is full where cost equals or exceeds the gain and proportionate where it is less. If those specified equity shares are transferred within one year, the previously non charged gain is recaptured as capital gains in the year of transfer, and any deduction claimed by reference to that cost is disallowed.
