A purchase price allocation is a reconciliation problem, not a presentation problem. ASC 805 requires identifiable assets and liabilities to be recognized separately from goodwill and measured at acquisition-date fair value. ASC 820 controls how that fair value is developed. PCAOB standards govern how the auditor evaluates the resulting work. None of that is news. What’s easy to miss is what those frameworks do together: they require a single, internally consistent acquisition-date story, told across multiple valuation disciplines, that an experienced reviewer can audit end to end.
That’s where mixed-asset PPAs come apart. The deal model uses one set of assumptions. The real estate appraisal uses another. The intangibles model attrition curve was built before the integration plan got finalized. The contingent consideration discount rate doesn’t match the WACC reconciliation. The fixed-asset team didn’t know about the purchase-accounting elections the lawyers locked in last week. Each schedule looks fine on its own, and the audit comments come from the seams.
What auditors are actually trying to prove
Audit teams aren’t doing a cosmetics check. The PCAOB’s estimates standard requires them to test management’s process, develop an independent expectation, evaluate subsequent events, and assess whether significant assumptions have a reasonable basis (meaning the assumptions hold up against external conditions, company strategy, and other estimates already in the financial statements). Inquiry and math-checking are not enough on their own. The May 2025 PCAOB Audit Focus on accounting estimates specifically warned about anchoring on management’s number and overweighting confirmatory evidence. That warning was written for PPAs, even if the title didn’t say so.
When a valuation specialist is part of the file, the audit obligation gets larger, not smaller. The auditor still has to test the company-produced data the specialist relied on, evaluate the relevance and reliability of external data, assess the reasonableness of specialist-developed assumptions, and conclude whether the methods are appropriate under the financial reporting framework. The PCAOB’s February 2025 specialist Spotlight called out files where the specialist’s report was simply dropped in. A credentialed report isn’t the same thing as audit-ready support.
Why the workstreams keep diverging
The difficulty in a mixed-asset PPA comes less from the number of asset classes than from the fact that each class is measured under a related but not identical model, and the assumptions have to reconcile to one transaction narrative. Real property uses ASC 820 fair value with highest-and-best-use; personal property leans on the cost approach with depreciation and obsolescence; identifiable intangibles go through customer-relationship MEEM, royalty rates, attrition curves, and useful lives; goodwill is the residual; liabilities and contingent consideration require their own measurement architecture. ASU 2021-08 changed how acquired contract assets and contract liabilities get measured, which matters in any service-heavy or recurring-revenue deal. And ASU 2025-03, effective for periods beginning after December 15, 2026, can change which entity is the accounting acquirer in certain VIE-related equity-exchange transactions, which can flip the entire purchase-accounting architecture.
A credentialed report doesn’t automatically translate into audit-ready support.
What PCAOB inspections show is actually being missed
The March 2025 PCAOB Spotlight on 2024 inspections covered 171 firms and parts of more than 800 issuer audits. The aggregate Part I.A deficiency rates were broad rather than PPA-specific, but they show why business-combination work remains a high-attention area:
The firm-specific reports show what those broad numbers actually mean inside business combinations:
Three themes show up across all four: data integrity, assumption support, and whether specialist work can actually be evaluated. Those are the seams a mixed-asset PPA produces.
What ASU 2025-03 changes for VIE acquirers
ASU 2025-03 is narrow but consequential. For acquisitions effected primarily through equity exchanges where the legal acquiree is a VIE that meets the definition of a business, the FASB now requires the entity to apply the general ASC 805 accounting-acquirer factors instead of defaulting to the VIE’s primary beneficiary. The change is effective for annual periods beginning after December 15, 2026, applied prospectively, with early adoption permitted.
This matters in PPA work for a simple reason. Changing the accounting acquirer changes which entity’s assets and liabilities are remeasured. That can flip the entire purchase-accounting architecture, and in qualifying cases, can produce a reverse-acquisition outcome that wouldn’t have been available under prior guidance. For deals that look like equity exchanges into VIE structures, this is a question to settle before the valuation work starts, not after.
An eight-point readiness checklist
The files that audit cleanly tend to do these eight things well:
The takeaway
In a mixed-asset PPA, the auditor is looking for support rather than presentation polish: complete data, reasonable assumptions, testable specialist work, methods appropriate to the financial reporting framework, and major conclusions reconciled into one acquisition-date narrative. When those elements are designed into the file from the start, audit review tends to be faster and narrower. When they aren’t, the report becomes the beginning of the audit discussion, not the end of it.
