Dear Sir / Madam,

Sub:- Margining in Cash Market.

1. This is further to SEBI Circular No.MRD/DoP/SE/Cir-07/2005 dated February 23, 2005 on the comprehensive Risk Management Framework for the cash market.

2. Currently in the cash market, VaR margin rate is calculated at the end of the trading day and then applied to the open positions of the subsequent trading day. However, in the derivative market, the risk parameter files for computation of the margins are updated intra-day.

3. With a view to ensure market safety and protect the interest of investors and also to further align the risk management framework across the cash and derivative markets, it has been decided that the risk arrays should be updated intra-day in the cash market as has been done in the derivative market. The applicable VaR margin rates shall be updated atleast 5 times in a day, which may be carried out by taking the closing price of the previous day at the start of trading and the prices at 11:00 a.m., 12:30 p.m., 2:00 p.m. and at the end of the trading session.
