PATMI is the acronym for Profit After Tax and Minority Interest. Imagine thr is a co. "A" and subsidiaries and works as a group. So when company A reports it will consolidate results of subsidiaries as well.
Group Pat is Net profit of group. If co. "A" doesn't own 100% in subsidiaries means that 3rd party have minority interests in the groups profit. So the profit available to company A's shareholders after apportioning for minority interest is PATMI.
