How do you build a purchase price allocation under ASC 805?

ASC 805Business combinationsPurchase accountingUpdated August 2026
The short answer

A purchase price allocation starts from consideration transferred at acquisition-date fair value: cash, equity at the closing-date price, and contingent consideration at fair value, with transaction costs expensed under ASC 805-10-25-23 rather than capitalized. Identifiable assets acquired and liabilities assumed — working capital, PP&E, and intangibles such as customer relationships and developed technology — are recognized at fair value under ASC 805-20-30-1, with deferred taxes recorded on the resulting book/tax basis differences. Goodwill is the residual of consideration (plus any noncontrolling interest and previously held equity interest, in less-than-100% or step acquisitions) over net identifiable assets (ASC 805-30-30-1); if net assets exceed the consideration, a reassessment and then a bargain purchase gain follow. Provisional amounts may be adjusted for up to one year under the measurement period guidance in ASC 805-10-25-13 through 25-14.

Start with consideration transferred

A purchase price allocation stands on three numbers: what you paid (consideration transferred), what you got (identifiable assets and liabilities at fair value), and the residual (goodwill). Get the first two right and the third falls out.

ASC 805-30-30-7 measures consideration transferred as the sum of the acquisition-date fair values of the assets transferred by the acquirer, the liabilities incurred to the former owners, and the equity interests issued:

  • Cash at the amount paid at closing, including seller escrows that secure general indemnification obligations, which are generally part of consideration — though the escrow terms should be analyzed, since release conditions can make an escrow contingent consideration or give rise to an indemnification asset. An escrow released only if a seller-employee keeps providing service is not consideration; it is post-combination compensation.
  • Equity issued at fair value on the closing date — the share price when control transfers, not the price when the deal was negotiated. On a volatile stock, the move between announcement and close can shift the allocation materially.
  • Contingent consideration at acquisition-date fair value (ASC 805-30-25-5), usually from a scenario-weighted or Monte Carlo model, not the maximum payout. Classification is set at inception under ASC 805-30-25-6: an obligation settled in cash, or in a variable number of shares, is generally a liability under the ASC 480 and ASC 815-40 analysis; settlement in a fixed number of shares can qualify as equity. The distinction has a long tail — liability-classified contingent consideration is remeasured to fair value every period through earnings until settled, while equity-classified amounts are never remeasured (ASC 805-30-35-1).

Two things never belong in consideration. Transaction costs — advisory, legal, valuation, diligence — are expensed as incurred under ASC 805-10-25-23; costs to issue debt or equity securities follow the applicable debt and equity guidance instead. And arrangements that forfeit if a selling shareholder stops providing service are compensation for post-combination service, not purchase price: ASC 805-10-55-25 treats automatic forfeiture on termination as determinative.

Recognize what you acquired, at fair value

ASC 805-20-25-1 requires recognizing, separately from goodwill, the identifiable assets acquired, the liabilities assumed, and any noncontrolling interest. ASC 805-20-30-1 measures them at acquisition-date fair value — an ASC 820 exit-price measurement from a market participant's perspective, regardless of what the acquirer plans to do with the asset.

Working through a typical balance sheet:

  • Receivables come on at fair value, not gross less an allowance: ASC 805-20-30-4 prohibits a separate day-one valuation allowance because collectibility risk is already in the fair value measure. Under CECL, the acquirer then establishes an allowance for expected credit losses on non-credit-deteriorated receivables through earnings immediately after the acquisition; purchased credit-deteriorated assets get a gross-up instead.
  • Inventory is stepped up. Finished goods are typically valued at estimated selling price less the remaining costs of the selling effort and a reasonable profit allowance for that effort, which lands well above the target's carrying amount. The step-up flushes through cost of sales in the first inventory turn — plan for the margin hit in the flux analysis.
  • PP&E at fair value, usually replacement cost adjusted for physical and functional depreciation, or market comparables for real property.
  • Debt assumed at fair value, which wipes out any premium, discount, or issuance costs the target carried.

Identifiable intangibles are where the valuation work concentrates. ASC 805-20-25-10 requires recognizing intangible assets separately from goodwill when they are identifiable — arising from contractual or legal rights, or separable from the business. The recurring set:

IntangibleWhy identifiableCommon valuation approachTypical amortization pattern
Customer relationshipsSeparable (contractual where relationships arise from contracts)Multi-period excess earnings method (MPEEM)Attrition-based, over the estimated relationship life
Developed technologyContractual-legal or separableRelief from royalty, or MPEEM when technology is the primary assetStraight-line over the technology's remaining life
Trade namesContractual-legalRelief from royaltyFinite life, or indefinite if renewal and use support it
Noncompete agreementsContractual-legalWith-and-without (differential cash flows)Contract term

The choice of method is a judgment coordinated with the valuation specialist: normally one asset in the group is valued under MPEEM and the others take royalty or cost methods, so the same cash flows are not counted twice. An assembled workforce is not recognized separately — ASC 805-20-55 subsumes it into goodwill — though it still gets valued as a contributory asset charge inside the MPEEM.

The fair value exceptions worth flagging

Not everything in the allocation is fair value. The exceptions preparers hit most:

ItemMeasured under
Income taxesASC 740, applied through ASC 805-740 — not fair value
Contract assets and contract liabilities (deferred revenue)ASC 606, per ASU 2021-08 — see below
Leases where the target is the lesseeASC 842: the lease liability is measured as if the lease were new at the acquisition date, and the right-of-use asset equals it, adjusted for favorable or unfavorable lease terms
Replacement share-based payment awardsASC 718 fair-value-based measure, split between consideration and post-combination compensation per ASC 805-30-30-9
Assets held for saleFair value less costs to sell
Indemnification assetsThe same basis as the indemnified item

On acquired leases, one more mechanic: the acquirer may elect, as a policy by class of underlying asset, not to recognize ROU assets and lease liabilities for acquired leases with a remaining lease term of 12 months or less (ASC 805-20-25-28A).

Deferred revenue: the rule changed

Before ASU 2021-08, acquired deferred revenue was fair valued — typically the cost to fulfill the remaining obligation plus a margin — which produced the familiar haircut: post-acquisition revenue vanished relative to what the target would have reported on its own.

ASU 2021-08 (codified in ASC 805-20) ended that. Contract assets and contract liabilities from contracts with customers are recognized and measured under ASC 606 as if the acquirer had originated the contracts. In most deals that means carrying over the target's deferred revenue balance, adjusted only where the target's ASC 606 accounting has to be conformed to the acquirer's policies or corrected. The standard took effect for fiscal years beginning after December 15, 2022 for public entities and a year later for everyone else, so a fair value haircut on deferred revenue in a current-year allocation is simply wrong.

Deferred taxes on the step-up

In a nontaxable acquisition — the typical stock deal — the target's tax bases carry over while the book bases reset to fair value. ASC 805-740-25-3 requires deferred taxes on the resulting differences: a deferred tax liability for intangibles recognized with no tax basis and for inventory and PP&E step-ups, and a deferred tax asset for acquired NOLs and other attributes, net of any valuation allowance assessed from the combined entity's perspective.

Two mechanics to keep straight. First, the DTL on the step-ups increases goodwill: it reduces net identifiable assets, and goodwill absorbs the difference. Second, no deferred tax is recognized on nondeductible goodwill itself — ASC 805-740-25-3 excepts it, which is what keeps the computation from circling forever. In a taxable asset acquisition, book and tax bases generally both reset, most of the temporary differences never arise, and goodwill is generally deductible for tax purposes. The tax structure of the deal changes the allocation, so confirm it with the tax team before building the table.

Worked example

Acquirer buys 100% of Target's stock on June 30 for cash, shares, and an earnout. The deal is nontaxable and the applicable tax rate is 25%. Transaction costs are $2.0 million. The earnout is capped at $12.0 million; its acquisition-date fair value is $5.0 million and it settles in cash, so it is liability-classified.

Consideration transferred$000
Cash at closing70,000
500,000 acquirer shares at the $30 closing-date price15,000
Contingent consideration at fair value (not the $12.0M cap)5,000
Total90,000

The $2.0 million of transaction costs stay out of the table and go to expense. The allocation:

Identifiable assets and liabilities$000
Cash acquired3,000
Accounts receivable9,000
Inventory (carrying amount 6,000 plus step-up 1,000)7,000
Prepaid and other current assets1,000
Property, plant and equipment (tax basis 9,000)12,000
Developed technology15,000
Customer relationships20,000
Trade name4,000
Noncompete agreement1,000
Accounts payable and accrued liabilities(8,000)
Contract liability (deferred revenue at the ASC 606 carryover amount)(4,000)
Deferred tax liability: 25% x (40,000 intangibles + 1,000 inventory + 3,000 PP&E)(11,000)
Net identifiable assets49,000
Goodwill (90,000 - 49,000)41,000

For simplicity, the example assumes Target has no NOLs, no pre-existing deferred taxes, and no other book/tax differences; in practice the deferred tax line nets the DTL on the step-ups against acquired deferred tax assets (including any DTA related to the assumed contract liability), assessed from the combined entity's perspective.

Because the deal is a nontaxable stock purchase, the goodwill is not tax-deductible and carries no deferred taxes. Going forward, the intangibles amortize over their assigned lives, the earnout liability is remeasured through earnings each quarter, and the inventory step-up burns off through cost of sales as the acquired units sell.

Goodwill as the residual, or a bargain purchase

ASC 805-30-30-1 measures goodwill as the excess of (a) consideration transferred, plus the fair value of any noncontrolling interest, plus the acquisition-date fair value of any previously held equity interest, over (b) the net identifiable assets recognized. US GAAP measures a noncontrolling interest at full fair value, and in a step acquisition the previously held interest is remeasured to fair value with the gain or loss in earnings (ASC 805-10-25-10).

When (b) exceeds (a), you have a potential bargain purchase. Before recognizing anything, ASC 805-30-30-5 requires a reassessment: recheck that every asset and liability has been identified, and review the measurement procedures, because an apparent gain is more often a missed liability or an overvalued intangible than a genuine bargain. If the excess survives the reassessment, it is recognized as a gain in earnings on the acquisition date (ASC 805-30-25-2), attributed entirely to the acquirer. Expect audit scrutiny in proportion to the gain.

The measurement period

Valuations rarely finish by the first reporting date after closing. ASC 805-10-25-13 through 25-14 let the acquirer report provisional amounts and adjust them as information arrives about facts that existed at the acquisition date, over a measurement period that ends when the acquirer obtains the information it was seeking — and no later than one year from the acquisition date. Since ASU 2015-16, measurement-period adjustments are recognized in the period they are determined, with the cumulative earnings effect (catch-up amortization on a revised intangible value, for example) booked in that same period rather than by revising prior periods. ASC 805-10-50 requires disclosing which amounts remain provisional and why.

The discipline is in the boundary. The measurement period trues up estimates of conditions that existed at closing; new facts from post-close events — a customer lost in month four, a market downturn — are post-combination accounting, not allocation adjustments. After the one-year window closes, corrections are error corrections under ASC 250.

Where allocations go wrong

  • Fair-valuing deferred revenue out of habit. Since ASU 2021-08, contract liabilities follow ASC 606, and the haircut is gone.
  • Treating an employment-contingent earnout as consideration. Automatic forfeiture on termination makes it post-combination compensation (ASC 805-10-55-25).
  • Calling contingent consideration equity without working through ASC 480 and ASC 815-40, then discovering the remeasurement that should have been running through earnings.
  • Forgetting the deferred tax liability on the intangibles, which understates goodwill and surfaces later as an avoidable measurement-period adjustment.
  • No plan for the inventory step-up's hit to the first quarter's margin.
  • Booking a day-one valuation allowance against acquired receivables instead of fair value plus a separately established CECL allowance.

Frequently asked questions

Are transaction costs part of the purchase price?

No. Acquisition-related costs such as advisory, legal, valuation, and diligence fees are expensed as incurred under ASC 805-10-25-23. The exception is costs to issue debt or equity securities, which follow the applicable debt and equity guidance: debt issuance costs are deferred against the borrowing, and equity issuance costs reduce the proceeds recorded in equity.

How is contingent consideration accounted for after the acquisition date?

It depends on the day-one classification. Liability-classified contingent consideration is remeasured to fair value each reporting period with changes recognized in earnings until it settles; equity-classified contingent consideration is not remeasured, and settlement is accounted for within equity (ASC 805-30-35-1). Classification is determined at the acquisition date under ASC 480 and ASC 815-40, so getting it right at inception matters.

Is acquired deferred revenue still measured at fair value?

No. ASU 2021-08 requires contract assets and contract liabilities from customer contracts to be recognized and measured under ASC 606 as if the acquirer had originated the contracts, which generally carries over the target's deferred revenue balance rather than cutting it down to a fulfillment-cost-plus-margin fair value. The change is effective for all entities' current acquisitions, so the old haircut no longer applies.

How long do we have to finalize the purchase price allocation?

Up to one year from the acquisition date (ASC 805-10-25-13 through 25-14). Provisional amounts are adjusted as information about facts that existed at the acquisition date is obtained, with each adjustment and its cumulative earnings effect recognized in the period it is determined. Adjustments after the measurement period ends are error corrections under ASC 250, and changes driven by post-acquisition events are current-period accounting, not allocation adjustments.
