Investment firms shall be required to hold own funds equivalent to one quarter of their preceding year's fixed overheads.

The competent authorities may adjust that requirement in the event of a material change in a firm's business since the preceding year.

Where a firm has not completed a year's business, starting from the day it starts up, the requirement shall be a quarter of the fixed overheads projected in its business plan, unless an adjustment to that plan is required by the competent authorities.
