@Iborian, actually its completely legal if you do it smartly. Actually most tax authorities accept tax avoidance but not evasion.
Taking an example of Jubilee having branches all over they might use:
1. Expense acceleration tactics.
2. Expense delaying tactics.
3. Transfer pricing.
4. Thin capitalization.
5. Transfer of expenses using the matching principle.
6. Presentation currency as opposed to functional currencies (read exchange differences).
7. Determining whether a branch or subsidiary is in an inflationary or a hyperinflationary economy (read exchange difference)
And now that they are in Mauritius you have to keenly scrutinize their financials coz first i guess they registered as a GBL 1 company. This gives them the leeway not to fully disclose whatever operations they have and this will fully fall on the NSE on disclosure to the public. Makes it easy to transfer expenses, income, liabilities for tax purposes. In Mauritius they ask for a very simple statement of affairs(Balance sheet) & Income statement (both of which are not detailed).
That's why you'll realise most companies go for Subsidiaries rather than Branches when foraying to other markets.
