Short-term capital gains rate change raises tax on transfers after specified date; long-term gains threshold and rate adjusted. The amendment modifies taxation for Foreign Institutional Investors' gains from securities by changing the short-term capital gains rate based on whether transfers occur before or on/after the stated cutoff, and by increasing the exempt aggregate threshold and altering the long-term capital gains rate similarly for transfers before versus on/after that cutoff; the exempt limit applies on an aggregate basis and the changes operate retrospectively from the cutoff date.
