The collateral balance per short stock is calculated by multiplying the prior day's closing price by an adjustment factor based on the currency, rounding this value up, then multiplying by the number of shares.
For example, the collateral balance on a USD-denominated security would be:
Collateral Balance = (stock A prior day closing price x 102%, rounded up to the nearest 1.00) x (number of shares stock A) + (stock B prior day closing price x 102%, rounded up) x (number of shares stock B)
