Registration fee and compliance deadlines revised for foreign portfolio investors; late-fee payment preserves trading exit rights. A foreign portfolio investor must pay registration fees for every three-year block before the block begins; payment within thirty days after block expiry together with the prescribed late fee will be treated as timely. Failure to pay required fees and late fees while continuing to hold securities or derivatives permits sale or winding up of positions within three hundred and sixty days from expiry of the thirty-day period under terms specified by the Board; failure to wind up will lead to deemed write-off as prescribed.
