The minimum risk fund size shall not be less than NIS 200 million and the minimum share of each MAOF Clearing House member in the Risk Fund shall not be less than NIS 5 million.
Cash Deposit, Government Bonds and T-Bills are allowed as collateral, with the cash
portion included in the risk fund is not less than 25%.
