Deal accounting under ASC 805, decision by decision: what you bought, who bought it, what it is worth on the books, and the year you have to get it right.
We turn the signed deal into a documented opening balance sheet the first combined audit can test.
What ASC 805 requires, and the decisions that set the balance sheet
Key takeaways
What it is. The acquisition method turns a signed deal into an opening balance sheet: identify the acquirer, fix the acquisition date, measure identifiable assets and liabilities at fair value, and record goodwill as the residual.
Where it breaks. The business-versus-asset screen, acquirer identification in reverse mergers, intangible recognition and lives, earnouts that are compensation rather than price, and the deferred taxes that move goodwill.
How we help. We run the purchase price allocation, document each position, and carry the file through the measurement period and the first combined audit.
ASC 805 turns a signed deal into a balance sheet, and every step is a decision with earnings consequences that last for years: whether the target is a business at all, which party is the acquirer, what intangibles exist and what lives they carry, whether the earnout is price or payroll, and what the deferred taxes do to goodwill. The first audit after a deal tests all of it at once.
This page goes decision by decision with the treatment for each. The deal-lifecycle view, diligence, pegs, net debt, sits on our M&A advisory page; reverse recapitalizations for SPAC targets sit on the SPACs page. Here we take the purchase accounting itself deep.
The standard
Goodwill in a business combination: the calculation
The acquisition method turns a signed deal into an opening balance sheet, and goodwill falls out of it as the residual: consideration transferred, plus noncontrolling interest and the fair value of any previously held interest, less the fair value of the net identifiable assets acquired. The judgment sits in the pieces, whether an earnout is price or compensation, what the deferred taxes do, and what happens when the residual comes out negative. We run the full purchase price allocation and document each position.

Scope
The screen test before purchase accounting
Before any of that, one screen decides which rulebook applies. If substantially all of the fair value is concentrated in a single asset or group of similar assets, the deal is an asset acquisition: no goodwill, transaction costs capitalized, and cost allocated on relative fair value. Otherwise, with an input and a substantive process, it is a business combination, and the acquisition method runs in full. The screen is the first question in every deal memo, and it changes goodwill, expense timing, and the intangibles you recognize.

After the close
Measurement-period adjustments after closing
The opening balance sheet does not have to be final on day one. Provisional amounts are allowed wherever the accounting is incomplete, and new information about facts that existed at the acquisition date adjusts them, and goodwill, in the period it is determined. The window ends when the information is complete or one year passes, whichever comes first. Intangible valuations, deferred taxes, and pre-acquisition contingencies are what usually finalize late, and information about events after the close belongs to the period it happens in, not to purchase accounting.

Our Experience
Where we have done this work
Engagement Notes
Platforms, add-ons, and first combined audits
Purchase accounting across sponsor platforms and strategic acquirers: screen memos at signing, allocations with valuation coordination, the deferred tax circle computed rather than plugged, and measurement-period logs that closed the year with no items converting into errors. The first combined audit tested one documented package per deal.
Engagement Notes
Consideration classification before the ink dried
Earnout and rollover classification engagements run against live purchase agreements: compensation-versus-consideration memos delivered during drafting, replacement award splits computed at signing, and the share-settled earnout analysis under 815-40 coordinated with the same framework we apply on SPAC earnouts.
The Detail
The gaps, and how we close each one
Issue 01
Business or asset acquisition: the screen and the substantive processDefinition of a Business
The first decision changes every later one: business combinations create goodwill, expense deal costs, and fair-value earnouts; asset acquisitions do none of that. The screen test resolved most real estate and single-product deals, but the middle cases still require the full framework.
The treatment
Apply the screen first: if substantially all the fair value of the gross assets acquired is concentrated in a single identifiable asset or a group of similar assets, it is an asset acquisition; similar means similar in nature and risk (a portfolio of like properties yes, a compound plus a manufacturing plant no). Deals that pass the screen still need a business: an input plus a substantive process that together significantly contribute to creating outputs, where an acquired organized workforce with the skills to convert inputs is the strongest evidence, and acquired contracts alone (customer lists, outsourced management agreements) generally are not processes. The consequences table drives why it matters: asset acquisitions capitalize transaction costs, allocate on relative fair value, recognize no goodwill, expense acquired IPR&D without alternative use, and account for contingent payments largely as they resolve. Write the screen memo at signing, on the deal’s actual asset mix, because restructuring the answer after close is not available.
What we do: We write the screen memo at signing on the deal's actual asset mix.
Issue 02
Identifying the acquirer and the acquisition dateAcquirer & Date
Someone is the acquirer, and in stock deals, mergers of equals, and structures with new holding companies, it is not always the party writing the press release. The acquisition date, when control transfers, is equally consequential and occasionally earlier or later than the day the deal closes.
The treatment
Identify the acquirer through ASC 810 control first, and where that is unclear, the ASC 805 factors: relative voting rights after the deal, large minority holders, board composition, senior management continuity, the party paying a premium, and relative size. New holding companies formed to effect a deal are looked through to the combining entities. When the accounting acquirer is not the legal acquirer, the deal is a reverse acquisition: the legal target’s financial statements continue, with the mechanics we cover for SPAC structures applying to operating-company reverses too. The acquisition date is the date control transfers, ordinarily closing, but written agreements can shift effective control earlier, and regulatory conditions can hold it later; measure everything, consideration fair values, exchange ratios, the opening balance sheet, at that date. The acquirer memo is two pages that determine whose history the combined company carries; write it before the structure is final, because structure drives the answer.
What we do: We deliver the acquirer and acquisition-date memo before the structure is final, when it can still inform it.
Issue 03
What gets recognized: intangibles, leases, and ASU 2021-08Recognition
The allocation is where the deal model becomes the opening balance sheet: which intangibles are identifiable, what happens to the target’s leases and deferred revenue, and how the exceptions to fair value, income taxes, contract items, leases, actually work.
The treatment
Recognize intangibles that are separable or contractual-legal: customer relationships (valued off attrition-adjusted revenue, usually the excess-earnings method), developed technology, trade names (occasionally indefinite-lived where the brand is the business), backlog, and noncompetes; assembled workforce folds into goodwill. Acquired leases: the target’s lessee leases remeasure as if new at the acquisition date (classification retained absent modification), with favorable or unfavorable terms folded into the ROU asset rather than separate intangibles. ASU 2021-08 removed a long-standing problem: contract assets and deferred revenue come over at ASC 606 carrying amounts, ending the fair-value haircut and the post-deal revenue dip, so diligence and models should stop assuming one. Contingencies recognize at fair value when determinable; indemnification assets mirror the indemnified item. The allocation memo, valuation report, and the deal model must reconcile, because auditors read them side by side.
What we do: We prepare the allocation with valuation coordination, acquired-lease remeasurement, and ASU 2021-08 applied.

Consideration: earnouts, compensation, escrows, and rolloverConsideration
What was actually paid is rarely one wire: earnouts, escrows, holdbacks, working capital true-ups, replacement awards, and rollover equity all sit somewhere between purchase price and compensation, and the classification moves millions between goodwill and the income statement.
The treatment
Contingent consideration measures at fair value at the acquisition date, classified as a liability (remeasured through earnings, so outperformance creates expense) or equity (fixed) under the 815-40 framework for share-settled arrangements. The compensation screen comes first: payments forfeited on termination of employment are compensation, and the other indicators, duration linked to employment, pay proportional to ownership versus salary, the formula’s logic, resolve the closer cases; this is one sentence of drafting worth reviewing before signature. Escrows and holdbacks securing reps are generally consideration paid, with the receivable side analyzed if recovery is expected; working capital true-ups adjust consideration when they settle the closing mechanism. Replacement awards split between consideration (pre-combination service) and post-combination compensation by the vesting ratio formula, and rollover equity is consideration unless service terms attach. One classification memo covering every payment stream in the deal is the deliverable.
What we do: We classify every payment stream, earnouts, escrows, replacement awards, rollover, in one memo, during drafting.
From our engagements: The earnout-versus-compensation line is the single ASC 805 issue we are asked to fix after signing most often, and the one cheapest to fix before it. We read the earnout section of every purchase agreement we touch for exactly this sentence.
Issue 05
Deferred taxes, goodwill, and the private-company alternativesASC 740 / 350
Purchase accounting manufactures deferred taxes: book basis steps up, tax basis often does not, and the resulting DTLs feed goodwill in a circle that confuses every first-time deal team. Then goodwill itself needs a home: impairment testing, or the private-company alternatives.
The treatment
Recognize deferred taxes on every book-tax basis difference the allocation creates: in a stock deal without a tax election, intangible step-ups generate DTLs (which increase goodwill, the circular calculation is iterative and standard), acquired NOLs come over as DTAs subject to Section 382 limitation analysis, and valuation allowances reassess in the combined context, with releases attributable to the acquisition recorded in the allocation. Asset deals and 338/336(e) elections align tax basis and shrink the deferreds, a structuring conversation to have before close, not after. Goodwill then tests annually and on triggers at the reporting unit under the one-step model; private companies may elect to amortize goodwill over ten years or less and to subsume customer relationships that cannot be sold separately and noncompetes into goodwill, elections that trade public-company comparability for real simplification, made deliberately with the exit path in mind, because unwinding them for an IPO is expensive. Bargain purchases, after a mandatory re-check of the math, book a gain.
What we do: We compute the deferred tax circle, run the 382 analysis on acquired NOLs, and paper the private-company elections with the exit in mind.
Issue 06
The measurement period, pushdown, and the disclosure setMeasurement Period
The year after close is when provisional numbers become final, the acquiree decides whether to push the new basis into its own books, and the disclosure package, including the pro forma revenue and earnings nobody remembers to compute, comes due in the combined financial statements.
The treatment
Use the measurement period honestly: up to one year from close, only for new information about facts that existed at the acquisition date, with adjustments recorded against goodwill and the cumulative earnings effect (depreciation, amortization) recognized in the period of adjustment, disclosed as such; information about post-close events, a customer lost in month four, is not a measurement period adjustment, and errors are restatements. Track open items, valuations pending, tax returns unfiled, working capital unsettled, on a measurement-period log with a hard one-year clock. Pushdown is the acquiree’s irrevocable election upon change of control, usually taken in sponsor deals to align standalone books with the new basis (see our private equity page). The disclosure set for material deals includes the allocation, consideration components, goodwill drivers and deductibility, acquiree revenue and earnings since close, and the supplemental pro forma revenue and earnings as if the deal closed at the start of the prior year, the disclosure most often missing from first drafts.
What we do: We run the measurement-period log to the one-year clock and prepare the disclosure set including the supplemental pro formas.
FAQ
Frequently asked questions
Is our deal a business combination or an asset acquisition?
Run the screen: fair value concentrated in one asset or a similar-asset group means asset acquisition. Past the screen, a business needs inputs plus a substantive process, usually an organized workforce. The answer changes goodwill, deal costs, IPR&D, and earnout accounting, so we memo it at signing.
Why does our earnout create expense when we beat plan?
Liability-classified contingent consideration remeasures at fair value each period, so a higher expected payout runs through earnings. It is correct and counterintuitive, and it belongs in the model before close. Equity-classified share-settled earnouts avoid remeasurement when the 815-40 conditions are met.
Where does goodwill actually come from in the calculation?
It is the residual after consideration is allocated to identifiable net assets at fair value, including the deferred tax liabilities the step-up creates, which is why goodwill and DTLs are computed iteratively. Nondeductible goodwill in stock deals is the normal outcome, and the deductibility disclosure is required.
Can we adjust the allocation eight months after close?
Only for new information about facts existing at the acquisition date, recorded against goodwill with the earnings catch-up disclosed. New developments are current-period events, and anything past the one-year mark is an error correction. The measurement-period log is what keeps the distinction clean.
Should our portfolio company elect the private-company goodwill alternatives?
Amortizing goodwill and subsuming certain intangibles genuinely simplifies life, but the elections complicate a future IPO or sale to a public buyer, where the accounting gets rebuilt. We decide it with the exit path on the table.
How do you handle a transaction where we are not sure whether it qualifies as a business combination?
That uncertainty is exactly where we start. We run the screen test and the business definition against the deal’s actual facts, document the conclusion, and model the accounting both ways where it is genuinely close, because business-combination and asset-acquisition treatment diverge on goodwill, transaction costs, IPR&D, and contingent consideration. The memo is written at signing, when the answer can still inform the structure.
What is a common control transaction, and how is it different from a business combination?
A common control transaction is a transfer of businesses between entities controlled by the same parent, a reorganization within a corporate group rather than an acquisition from a third party. It is outside the ASC 805 acquisition method: the receiving entity generally records the assets and liabilities at the transferor’s historical carrying amounts (not fair value), no goodwill arises, and prior periods are often presented as if the combination had always existed. Identifying common control early matters, because applying purchase accounting to what is really a common control transaction is a restatement risk.
Do you work with foreign companies or international operations?
Yes. We regularly work with foreign private issuers and cross-border structures, including IFRS reporting, US GAAP reconciliations, and multi-entity consolidations across domestic and international subsidiaries.
How quickly can you get started?
Usually within a few days of finalizing the engagement: a brief discovery session, a clear statement of work, and secure access setup. We do not run lengthy intake procedures that delay the actual work.
