The deal has closed, the press release is out, and the integration meetings are already on the calendar. For the finance team, some of the hardest work is just beginning. Many executives underestimate what happens after closing. Once the deal is signed, the focus quickly shifts from transaction execution to financial reporting scrutiny. A purchase price allocation (PPA) under ASC 805 may sound straightforward at first, but it often becomes one of the more heavily scrutinized parts of the transaction. A PPA is not just about compliance; it is where the acquisition story gets translated into numbers that investors, auditors, and boards will continue to evaluate long after the deal closes.

The PPA Impacts Future Earnings

At a basic level, a PPA requires the acquirer to measure the fair value of acquired assets and assumed liabilities, with any residual value recorded as goodwill. The implications, however, go much further. The PPA affects:

• Future amortization expense,
• Potential future impairment write-offs,
• Reported earnings,
• Audit complexity, and
• How investors ultimately evaluate the transaction.

In many deals, the most heavily scrutinized areas involve intangible assets such as customer relationships, developed technology, and trade names. Their assigned values and useful lives directly affect post-acquisition earnings. It is in this area where valuation judgment matters most.

Customer relationship valuations often depend on factors such as attrition assumptions, renewal rates, projected margins, and risks, such as customer concentration. Developed technology valuations often raise questions around obsolescence and future development cycles. Brand and trade name analyses require support for long-term economic relevance and market positioning.

Deferred tax impacts can also become significant, particularly when large intangible assets are recognized for book purposes but not tax purposes. In some transactions, the deferred tax adjustment materially affects the amount ultimately recorded as goodwill.

These judgments directly affect future earnings, which is why auditors spend so much time challenging the assumptions behind them. They are forward-looking judgments about how the acquired business will actually generate value after closing.

Audit Pressure Starts Immediately

Many companies assume the difficult part ends once the deal documents are signed. In reality, the audit clock starts immediately. Although ASC 805 allows up to one year to finalize the allocation, auditors typically want support much earlier. Companies need reasonable preliminary estimates, supported by clear documentation, to provide a basis for any later adjustments. When assumptions are inconsistent or poorly documented, the process slows down quickly. Usually, the issue is not the valuation model itself, it’s that different teams relied on different assumptions during the deal process.

Auditors routinely compare the PPA against:

• Deal models,
• Diligence findings,
• Board materials,
• Synergy assumptions, and
• Forecasts used elsewhere.

When those narratives do not align, scrutiny increases quickly. Finance teams revisit models, management re-explains projections, and auditors request supplemental support. In some cases, the controller is reconciling multiple forecast versions while auditors are asking why retention assumptions differ from the original deal model. Auditors often focus first on customer attrition assumptions because small changes can materially affect the value assigned to customer relationships. For example, a deal justified internally by aggressive cross-selling assumptions cannot simultaneously rely on highly conservative customer retention assumptions without raising questions.

Low-Cost PPAs Often Become Expensive

Companies sometimes treat PPAs as interchangeable compliance deliverables. That approach can become expensive later. Lower-cost providers may save money upfront. But if the analysis does not hold up during audit review, the costs show up later in the process. The result is often:

• Additional documentation requests,
• Revised assumptions,
• Compressed reporting timelines, and
• Increased management involvement.

In some cases, companies effectively pay for the work twice. The issue is not firm size, it is whether the valuation is technically sound, well-supported, and capable of surviving audit scrutiny without unnecessary disruption. The smoothest PPAs usually start before closing. The companies that navigate the process most efficiently usually start addressing valuation issues during diligence rather than after closing. When the valuation, diligence findings, and financial reporting assumptions all tell the same story, the audit process tends to move much more efficiently.

The Takeaway

A purchase price allocation is often viewed as a technical accounting requirement. In reality, it is one of the first major tests of whether the economics of the transaction hold up under external scrutiny. Done well, the process supports credibility with auditors, investors, and boards. Done poorly, it creates avoidable friction that can linger long after the deal closes.
