A. Taxes paid are never considered as "EXTRA-ORDINARY ITEM"...
B. Its just the way of presentation that CF from WC/OPERATING ACTIVITIES before tax and after tax..
C. And as interest or dividend is alwz received post-tax, the same will be shown on its net income in Investing activities..
D. And if there is any operating income or any other income, other than that mentioned in (c) above, will be received net of tax so will be shown at its net figure only.
