Minority Interest
The share of a partly owned subsidiary's equity that belongs to outside shareholders, not the parent.
What it is
Minority interest, now usually called non-controlling interest (NCI), is the portion of a consolidated subsidiary that the parent company does not own. When a parent controls but does not fully own a subsidiary, it consolidates 100% of that subsidiary's results, then sets aside the outside owners' slice. It appears within the equity section of the balance sheet.
Why it matters
Because the parent reports the whole subsidiary, minority interest tells you how much of the consolidated assets and profits actually belong to other investors. Ignoring it overstates what the parent's own shareholders own and earn. It matters most for holding companies and conglomerates with many partly owned units.
How it's calculated
It is the outside ownership percentage applied to the subsidiary's net assets (for the balance sheet) and to its net income (for the income statement).
How Quintarthai uses it
Non-controlling interest shows up in the equity section and as a deduction from net income on the Financials tab of a company page for groups with partly owned subsidiaries.
