The Independent Communications Authority of South Africa amended the regulations regarding annual contributions to the Universal Service Fund on 10 Feb 2011.  There are two noteworthy changes from the previously applicable regulations.  The first is that the annual contributions will be due six (rather than three) months after a licensee's financial year end.  This makes the due date simultaneous with the due date for annual licence fees applicable to service licences.  The second is that the definition of "annual turnover", the basis upon which contributions are calculated, has been change to allow deductions for "service provider discounts, agency fees, interconnection and facilities leasing charges, government grants and subsidies".
