Debt investment allocation to FIIs via open bidding platform; price-based allocation with time priority and utilisation deadline. An open bidding platform administered by stock exchanges will allocate a designated portion of FII corporate debt investment capacity. Bids, placed via trading members, are priced in basis points and allocated by price then time priority. The procedure specifies minimum bid and tick sizes, a minimum flat fee or the bid price payable by successful bidders, conversion of limits into rupee terms at the RBI reference rate on bid date, and a per-entity allocation cap; utilisation periods and a separate first-come, first-served route for smaller allocations are also prescribed.
