THE Securities and Futures Commission (SFC) has teamed up with Britain's Investment Management Regulatory Organisation (Imro) to strengthen supervision on cross-border investment management activities. The market watchdogs yesterday announced the signing of a joint declaration to step up co-operation in the supervision of investment management activities that take place in Hong Kong, Britain or simultaneously in both. The declaration, signed in London by SFC chairman Anthony Neoh and Imro chairman Charles Nunneley, tightened the monitoring grip on fund management companies registered under SFC or Imro jurisdiction. The authorities would share reports of inspection visits to dual registrants on a regular basis and exchange information concerning fund managers, investment advisers and others involved in investment management. The declaration also allowed the authorities to help each other in inspection visits.
