Closing an acquisition feels like the finish line. For the finance team, it’s closer to the starting gun for a detailed accounting exercise most of them have never actually performed before: purchase price allocation.

Purchase price allocation, or PPA, is a valuation exercise required under Accounting Standards Codification 805 whenever a company acquires another business. It involves assigning the total purchase price to the fair value of every identifiable asset and liability acquired, tangible and intangible. Most finance teams underestimate how much work that sentence actually contains.

What Is Purchase Price Allocation and Why Does It Matter After an Acquisition Closes?

PPA exists to make sure the acquiring company’s financial statements accurately reflect what was bought, at fair value, as of the acquisition date. That sounds procedural. In practice, it requires answering a series of genuinely difficult questions.

The purchase price itself often isn’t a single number. It can include cash paid at close, contingent consideration tied to the acquired business’s future performance, equity interests issued to former owners who stayed on, and assumed or issued debt, each of which may require its own fair value assessment under separate accounting guidance.

Once that total is established, it has to be allocated across every identifiable asset and liability acquired, including intangible assets like customer relationships, trademarks, and technology that didn’t previously appear on the acquired company’s balance sheet at all. Whatever’s left over becomes goodwill, calculated as the excess of the purchase price over the fair value of everything else identified.

None of this is optional paperwork. It directly shapes the acquiring company’s post-close balance sheet, its future depreciation and amortization expense, and its exposure to goodwill impairment down the road. If you get it wrong, the effects don’t stay contained to one transaction. They show up in every reporting period afterward.

How Long Does Purchase Price Allocation Typically Take, and What Can Delay It?

PPA is genuinely complex, and complexity takes time. Identifying separately identifiable intangible assets typically requires engaging a valuation specialist, who needs detailed historical and projected financial information from the acquired business to do that work credibly. Assembling that information, especially from a target company whose own records may not have been kept with a future PPA in mind, is often the single biggest source of delay.

A few specific areas tend to slow the process down further. Contract assets and liabilities require close coordination with project managers if the acquired business recognizes revenue over time, since proper cutoff calculations depend on understanding the status of every open project as of the acquisition date. Unrecorded liabilities are another common snag, since vendor invoices and cash disbursements received after close must be traced back to determine whether they belong to the pre- or post-acquisition period. Inventory requires its own physical count around the acquisition date, along with an honest look at slow-moving or obsolete stock that may need a reserve.

None of this is unusual. It’s simply more involved than the phrase “allocate the purchase price” suggests to a finance leader encountering it for the first time.

What Happens If a Company Doesn’t Complete Purchase Price Allocation Correctly?

The immediate consequence is an opening balance sheet that doesn’t hold up to audit scrutiny. Auditors reviewing a PPA will request the purchase agreement, operating and credit agreements, working capital adjustments, and the funds flow schedule, and they’ll test the opening balance sheet with the same rigor applied to a fiscal year-end close. Documentation gaps discovered at that stage tend to produce material adjustments, not minor ones.

There’s also a real time constraint most buyers aren’t aware of going in. Fair value measurements are based on facts and circumstances as of the acquisition date, and the accounting guidance provides a limited window, generally up to one year from that date, to finalize provisional amounts as new information comes in. Waiting too long to start doesn’t just create a bottleneck. It can leave a company running out of runway to correct its own numbers within the window the standard allows.

Getting Ahead of It Instead of Discovering It Late

Alliance’s Mergers & Acquisitions practice includes purchase price allocation, opening balance sheet preparation, and fair value assessments as part of its core deal support. In one engagement, Alliance supported a newly acquired private equity portfolio company through its full purchase price allocation, providing everything from PPA journal entries and technical accounting memos to the daily accounting operations and audit readiness work needed to get the company reporting cleanly under its new ownership.

Key Takeaway: Purchase price allocation is real, time-sensitive accounting work that starts the moment a deal closes, not a formality to get to eventually. The buyers who avoid painful audit surprises are the ones who start gathering documentation and engaging a valuation specialist immediately after close, rather than treating PPA as something to circle back to once the integration settles down.
