The requirements specified in this Module vary according to the category of investment firm licensee concerned, their inherent risk profile, and the volume and type of business undertaken. The purpose of such requirements is to ensure that investment firm licensees hold sufficient capital to provide some protection against unexpected losses, and otherwise allow investment firms to effect an orderly wind-down of their operations, without loss to their customers or those of other firms. The minimum capital requirements specified here are not sufficient to absorb all unexpected losses.
