A central securities depository has rules, procedures and controls, including robust accounting, to protect the rights of issuers and holders, prevent unauthorised creation or deletion of securities, and reconcile issues at least daily. It prohibits overdrafts and debit balances in securities accounts; keeps securities immobilised or dematerialised for book-entry transfer; protects assets against custody risk; segregates its own assets from participants' securities and participants' holdings from each other, supporting segregation of customer holdings where law allows; and manages risks from its other activities.
