I am having 1000 equity shares of A Ltd. since 1992-93. In 2009, A Ltd. demerged a division and a new company was formed in the name of B Ltd. Accordingly shares of B Ltd. were alloted to me and today I am having 700 equity shares of A Ltd. and 300 equity shares of B Ltd. Now when i sell the shares of B Ltd., how do I calculated the period of holding for the purpose of calculating long term / short term capital gains? Also, from when do I get the indexation benefit?
Please advise.
