What this topic is
When a parent controls a subsidiary it does not wholly own, it consolidates 100 percent of the subsidiary's assets, liabilities, revenues, and expenses, and then presents the portion of equity and earnings belonging to the other owners as a non-controlling interest. ASC 810 governs when consolidation is required and how the non-controlling interest is measured, presented, and adjusted as ownership changes.
Why it matters
The accounting draws a hard line at control, and the line produces results that surprise people. Moving from 80 percent to 100 percent, a real transaction with real cash, produces no gain or loss and does not touch goodwill. Moving from 60 percent to 40 percent produces a gain measured on the entire investment, including the part you kept, frequently a very large non-cash gain. Same direction of travel, opposite accounting, and the difference is whether control changed hands.
Who should learn it
Controllers and technical accounting teams, corporate development, analysts modelling groups with material minorities, joint venture and tax equity practitioners, and anyone computing earnings per share for a group with partially owned subsidiaries.
What you will understand
- Why the non-controlling interest sits in equity and what that does to every ratio built on equity
- The equity-transaction rule for ownership changes that do not change control, and its mirror in the deconsolidation gain
- How the non-controlling interest is measured at acquisition, and where US GAAP and IFRS genuinely differ
- Redeemable non-controlling interests, mezzanine classification, and their effect on earnings per share
Prerequisites
Common misconception
"We bought the remaining 20 percent for $60M and its carrying value was $38M, so we recognized $22M of goodwill." No. A purchase of a non-controlling interest without a change in control is an equity transaction: the non-controlling interest is removed at its carrying amount and the entire difference goes to the parent's additional paid-in capital. No goodwill, no gain, no loss, and nothing in the income statement, even though real cash left the building.
