Indexed cost base changed for capital gains computation, altering base-year reference and effective assessment period.
Amendment revises the benchmark year used in the computation of the indexed cost of acquisition by replacing the earlier base-year reference with a more recent base year, with consequential changes to the mode of computation and prospective application to the stated assessment year and subsequent years, thereby altering the use of the Cost Inflation Index in proportionately adjusting cost of acquisition for capital gains.

Capital gains computation: rupee appreciation on redemption of rupee bonds held by non-residents excluded from full value.
Amendment clarifies that for a non-resident holder of a rupee-denominated bond of an Indian company, any gain arising from appreciation of the rupee against a foreign currency at redemption shall be ignored in computing the full value of consideration for capital gains; the change substitutes "held by" for "subscribed by" and operates prospectively from the notified effective date.
