(28)For the competent authority to monitor and evaluate the risks to which the CSD is or may be exposed to and which may arise for the smooth functioning of securities markets, it should be able to request additional information on the risks and activities of a CSD. The competent authority should therefore be able to define and request on its own initiative, or following a request submitted to it by another authority, any additional information which it considers necessary for each review and evaluation of the activities of a CSD.
