What's the difference between partial goodwill and full goodwill in business combinations?

Question

This is one of the most testable IFRS/GAAP differences in the CFA Level II Financial Reporting curriculum. Let me walk through both methods.

**Setup:** Kensington Holdings acquires 80% of Waverly Technologies for $320 million. The fair value of Waverly's identifiable net assets is $350 million. The fair value of the 20% noncontrolling interest (NCI) is $78 million.

**Full Goodwill Method (Required under US GAAP, optional under IFRS):**

Goodwill = (Purchase price + Fair value of NCI) - Fair value of net assets
Goodwill = ($320M + $78M) - $350M = **$48 million**

NCI on balance sheet = $78M (at fair value)

**Partial Goodwill Method (IFRS option only):**

Goodwill = Purchase price - (Investor's share x Fair value of net assets)
Goodwill = $320M - (80% x $350M) = $320M - $280M = **$40 million**

NCI on balance sheet = 20% x $350M = **$70M** (proportionate share of net assets, no goodwill attributed to NCI)

**Comparison:**

| Item | Full Goodwill | Partial Goodwill |
|---|---|---|
| Goodwill | $48M | $40M |
| NCI (Balance Sheet) | $78M | $70M |
| Total Assets | Higher by $8M | Lower by $8M |
| Total Equity | Same | Same |

    D -->|Option 1| C
    D -->|Option 2| E["Partial Goodwill
(NCI at proportionate share)"]
```

**Why it matters for ratios:**
- Full goodwill produces higher total assets → lower ROA
- Full goodwill produces a higher NCI → same total equity but different composition
- The choice affects debt/asset ratios and return metrics in cross-border comparisons

**Exam tip:** If a vignette says the company elected to measure NCI at 'proportionate share of net identifiable assets,' that signals partial goodwill. If it gives you a separate fair value for the NCI, it's hinting at full goodwill.
