Deal Valuation and Purchase Accounting

Deal valuation and purchase accounting connect the price negotiated for control with the acquisition-date amounts reported after closing. Valuation asks what the buyer is willing to pay and why. Purchase accounting asks how consideration and acquired assets, liabilities, noncontrolling interests, and goodwill are measured under the applicable framework.

Choose the Right Concept

Use all three when analyzing a completed acquisition. They answer different questions and use different dates, evidence, and measurements.

Follow the Measurement Sequence

1. Set the valuation reference. Establish the unaffected share price, standalone value, diluted share count, debt, cash, and other claims.
2. Measure the offer. Reconcile per-share consideration to diluted equity value and enterprise value.
3. Test buyer economics. Compare the premium and total uses with standalone value, risk-adjusted synergies, integration cost, financing, and downside cases.
4. Identify the acquisition date. Determine when control transfers rather than relying automatically on announcement or signing.
5. Measure accounting consideration. Apply the relevant framework to cash, shares, contingent amounts, previously held interests, and other components.
6. Recognize acquired items. Identify and measure assets, liabilities, and qualifying noncontrolling interests.
7. Calculate residual goodwill or bargain-purchase result. Perform the applicable review and documentation.
8. Track later earnings. Record depreciation, amortization, inventory effects, financing, taxes, impairment, and post-acquisition operating results.

Worked Example: From Offer to Goodwill

Assume a buyer offers $30 per share for 10 million diluted target shares. The unaffected price is $24.

If the target has $80 million of debt and $20 million of cash, the simplified offer enterprise value is $360 million:

$300 million equity value + $80 million debt - $20 million cash = $360 million

After closing, assume accounting consideration is measured at $300 million and identifiable acquired net assets are measured at $245 million. The simplified residual is $55 million:

The $60 million offer premium and $55 million goodwill are not contradictory and should not be expected to match. The premium uses an unaffected equity-market reference. Goodwill is an acquisition-date accounting residual after measuring consideration and identifiable net assets under the applicable framework.

Keep the Measures Separate

Evidence to Review

• Unaffected date and price, market rumors, trading history, diluted capitalization, and option treatment.
• Purchase agreement, consideration terms, debt, cash, working-capital adjustments, and funds flow.
• Board forecasts, comparable-company and precedent analyses, synergy case, integration plan, and fairness materials where used.
• Acquisition-date balance sheet, asset and liability inventory, valuation reports, useful lives, and tax basis.
• Accounting memorandum, control date, contingent consideration, noncontrolling interest, and measurement updates.
• Post-closing depreciation, amortization, inventory charges, taxes, impairment, and consolidation workpapers.

Accounting and Tax Boundaries

The IFRS Foundation’s IFRS 3 overview summarizes acquisition-date recognition, measurement, goodwill, and disclosure principles for entities applying IFRS Accounting Standards. Entities using U.S. GAAP or another framework must follow that framework’s current requirements.

Book purchase accounting and tax allocation are separate. For qualifying U.S. transfers of business assets, the IRS instructions for Form 8594 describe reporting and residual-method allocation rules, including exceptions. Not every acquisition requires Form 8594, and book and tax amounts can differ.

Common Mistakes

• Using a price already affected by rumors as the unaffected reference without analysis.
• Treating control premium, synergy value, and goodwill as interchangeable.
• Comparing equity purchase price with enterprise value or total uses without a bridge.
• Omitting acquired intangible assets because they were not recognized by the target.
• Treating tax allocation and financial-reporting allocation as the same schedule.
• Using post-closing integration cost as part of goodwill without applying the relevant accounting rules.
• Interpreting higher post-acquisition earnings as proof that the buyer earned an adequate return.
