Regulations Governing Securities Finance Enterprises Article 25
A securities finance enterprise providing re-financing to a securities firm shall notify the securities firm to replenish the collateral or margin within the time limit or repay the shortfall if a decline in the price of the collateral for a margin purchase causes the ratio of the margin purchase amount to the collateral's market value to exceed the initial lending ratio; or if an increase in the price of securities sold short causes the short sale margin percentage to fall short of the initially collected percentage; or if an increase in the price of loaned securities or a decline in the price of collateral provided for the securities loan causes the ratio of the market value of the collateral to the market value of the loaned securities to fall short of the initial lending ratio.
