How is net income allocated between the parent and noncontrolling interest after an acquisition?

Great question — the NCI income allocation is a common source of errors on CFA Level II vignettes. Here's how it works:

Core Principle: After consolidation, the subsidiary's net income is allocated based on ownership percentages, but after fair value adjustments.

Step-by-Step Process:

1. Start with the subsidiary's reported net income
2. Adjust for fair value amortization (e.g., step-up on PP&E, intangible assets, inventory)
3. Allocate the adjusted net income between parent's share and NCI's share

Example:

Montclair Industries acquired 75% of Hargrove Metals for 240M. At acquisition, Hargrove's PP&E was undervalued by 20M (remaining useful life: 10 years) and inventory was undervalued by $4M (sold in year 1). In Year 1, Hargrove reports net income of$32M.

Adjusted subsidiary net income:

Item	Amount
Reported net income	$32.0M
- Extra depreciation ($20M / 10 years)	($2.0M)
- Inventory step-up amortization	($4.0M)
Adjusted net income	$26.0M

Allocation:

• Parent's share (75%): $26.0M x 75$19.5M**
• NCI share (25%): $26.0M x 25$6.5M**

On the consolidated income statement:

• Total consolidated net income includes parent's own operations plus 100% of Hargrove's adjusted results
• Near the bottom, NCI's share ($6.5M) is deducted to arrive at "Net income attributable to parent"

On the consolidated balance sheet:

• NCI equity increases by $6.5M (its share of earnings), minus any dividends paid to NCI shareholders

Key exam points:

1. Fair value adjustments reduce the subsidiary's adjusted income, affecting BOTH the parent's and NCI's shares
2. Under full goodwill, the NCI bears its share of goodwill impairment; under partial goodwill, only the parent does
3. Intercompany transactions must be eliminated before allocation
