Non-controlling interest

The share of a subsidiary that the parent does not own, shown separately inside consolidated equity and inside consolidated profit. It exists because consolidation adds 100% of a controlled subsidiary's revenue and assets even when the parent owns less than all of it.

A parent owning 74% of a subsidiary earning ₹1,400 crore consolidates the whole ₹1,400 crore, then deducts ₹364 crore as profit attributable to the other holders.

Two consequences follow for analysis. Earnings per share must use profit attributable to the parent's owners, not total consolidated profit. And consolidated revenue and margin belong to a group in which outsiders own a real slice, so a comparison against a wholly owned peer is not like for like.

Where minority interest is large, look at the subsidiary list and check where the profit actually sits.

Consolidation adds everything. Attribution takes some back.
