Positions in depository receipts may only be netted against positions in the underlying stock if the stock is freely deliverable against the depository receipt. If a bank takes a position in depository receipts against an opposite position in the underlying equity in different markets (i.e. arbitrage), it may offset the position provided that any costs on conversion are fully taken into account. Furthermore, the foreign exchange risk arising out of these positions should be included in the measurement framework as set out in chapter CA-11.
