The Mauritius authorities requested IMF technical assistance to reconcile the statistical treatment of Global Business Corporations (GBCs) in the national accounts and the balance of payments. An IMF mission worked with Statistics Mauritius and the Bank of Mauritius to investigate significant GDP discrepancies, which were found to arise mainly from survey coverage gaps and methodological shortcomings in the measurement of output for the various types of GBCs. Following the discussions, both institutions agreed to the mission’s proposals to revise the methodology used to compile output and investment income of GBCs, in order to strengthen accuracy and ensure consistency across datasets.
