Long-term capital gains tax treatment: different tax rates for unlisted securities with distinct computation rules for gains. The amendment differentiates tax treatment of long-term capital gains: generally subject to a higher rate, whereas gains from unlisted securities are taxed at a lower distinct rate and must be computed without giving effect to the first and second provisos to the capital gains computation provision. It also defines 'securities' by reference to the Securities Contracts (Regulation) Act and expressly distinguishes listed securities (those on recognised stock exchanges) from unlisted securities (all other securities).
