A Clearing Member shall call for additional margins from a Third Party (including a Customer) for whom the Clearing Member provides carrying and/or clearing services if at any time the Third Party's total net equity falls below the maintenance margins. Such additional margins posted should be sufficient to bring the relevant account up to the initial margins level, within a reasonable period. Nothing herein prohibits a Clearing Member from making a call for additional margins or imposing a stricter settlement period as it sees fit.

For settlement currency denominated in Japanese Yen, "reasonable period" in this Rule 7.22.4 means a period which shall not exceed three (3) Trading Days from the date that the Third Party's total net equity falls below the maintenance margins. For all other settlement currencies it means a period which shall not exceed two (2) Trading Days from the date that the Third Party's total net equity falls below the maintenance margins.
