Purchase Price Allocation (ASC 805) After an Acquisition

Purchase price allocation is the accounting process that assigns the total consideration paid in a business combination to each identifiable asset acquired and liability assumed, measured at fair value as of the acquisition date. Under ASC 805, Business Combinations, any remaining excess after those fair-value assignments is recognized as goodwill. The process is mandatory for every business combination under U.S. GAAP, regardless of deal size or structure, and must be completed within one year of closing.

What Is Purchase Price Allocation Under ASC 805?

ASC 805, issued by the Financial Accounting Standards Board (FASB), replaced the old pooling-of-interests method with the acquisition method. The standard requires an acquirer to recognize all identifiable assets and liabilities at their acquisition-date fair values, not at the target’s historical book values. Every business combination since 2009 has followed this framework.

A purchase price allocation (PPA) matters because it directly shapes the balance sheet the acquirer presents after closing. Assets recognized through PPA are then depreciated or amortized over their useful lives, affecting reported earnings for years. Goodwill, the residual figure, is tested for impairment annually (or more frequently if triggering events arise) rather than amortized under public company GAAP. Getting the PPA right is not a compliance checkbox; it determines the trajectory of post-deal financial statements.

The Four Steps of the Acquisition Method

ASC 805 organizes the acquisition method into four sequential steps:

Step 1: Identify the Acquirer

One party must be designated as the acquirer. This is usually the entity that transfers cash or other assets, but in complex structures the determination can be more nuanced. In 2025, the FASB issued ASU 2025-03, which refined the acquirer-identification rules when the legal acquiree is a variable interest entity and equity interests are exchanged. The revised guidance applies to fiscal years beginning after December 15, 2026, with early adoption permitted.

Step 2: Determine the Acquisition Date

The acquisition date is typically the closing date, when the acquirer obtains control. This date locks in the exchange rates, market prices, and interest rate environment used to measure fair values throughout the PPA.

Step 3: Recognize and Measure Identifiable Assets and Liabilities

Every identifiable asset and assumed liability is recorded at fair value on the acquisition date. This step is the substantive work of a PPA. It forces the acquirer to surface assets that never appeared on the target’s books at all, such as internally developed customer relationships or trade names that were expensed as incurred.

An intangible asset qualifies for separate recognition from goodwill if it meets either the contractual-legal criterion (it arises from a legal right, regardless of whether that right is transferable) or the separability criterion (it could be sold, licensed, transferred, or exchanged independently, or in combination with a related contract or asset). These are tests of recognizability, not marketability.

Step 4: Recognize Goodwill or a Bargain Purchase

Goodwill is the arithmetic residual:

Goodwill = Consideration transferred + Fair value of any noncontrolling interest + Acquisition-date fair value of any previously held equity interest – Net identifiable assets at fair value

In the rare case where fair-value net assets exceed consideration, the difference is a bargain purchase gain recognized immediately in earnings after reassessing all assumptions.

Identifying and Valuing Intangible Assets

The most judgment-intensive part of a PPA is identifying and valuing intangible assets that were not on the target’s balance sheet. Common categories include:

Marketing-related intangibles: Trade names, trademarks, domain names, non-compete agreements. These are typically valued using the relief from royalty method, which calculates the present value of royalty payments the acquirer avoids by owning the asset rather than licensing it. Each year’s cash flow equals revenue multiplied by an estimated royalty rate, tax-effected, then discounted to present value.

Customer-related intangibles: Customer relationships, customer lists, order backlog. The multi-period excess earnings method (MPEEM) is the most common approach here. It isolates cash flows attributable to the customer base after charging contributory asset returns for all other assets supporting those cash flows.

Technology-based intangibles: Developed technology, patents, trade secrets, proprietary software. Depending on the availability of comparable licensing data, either the relief from royalty or MPEEM is used.

Contract-based intangibles: Favorable lease agreements, licensing arrangements, supply contracts, franchise agreements. These are valued by modeling the economic benefit (or obligation) relative to current market terms over the remaining contract period.

In middle-market acquisitions, identified intangibles often represent 30 to 60 percent of total consideration. The quality and thoroughness of this identification step determines how much of the purchase price ends up in goodwill versus depreciable or amortizable assets, which has significant implications for post-deal earnings.

Transaction costs, including legal fees, advisory fees, and due-diligence expenses, are not part of the purchase price under ASC 805. They are expensed in the period incurred and never capitalized onto the balance sheet.

The Measurement Period

ASC 805 recognizes that a complex acquisition may not have all facts available at the closing date. The standard allows an acquirer to record provisional amounts for items where accounting is incomplete, subject to a measurement period that cannot exceed one year from the acquisition date.

Measurement period adjustments are not corrections of errors. They reflect new information about facts and circumstances that existed as of the acquisition date that, if known at closing, would have changed the initial measurements. An acquirer revises provisional amounts retrospectively, as if the final amounts had been known on day one, adjusting comparative financial statements accordingly. Once an acquirer determines it has gathered all reasonably obtainable information, the measurement period closes, even if that is before the one-year mark.

Goodwill Accounting After the PPA

Once goodwill is established, the treatment depends on who is reporting.

Public companies follow ASC 350, which prohibits amortization of goodwill. Instead, goodwill is tested for impairment at least annually, and whenever a triggering event indicates the reporting unit’s fair value may be below its carrying amount. The impairment charge, if any, equals the excess of carrying value over fair value, limited to the carrying amount of goodwill in the reporting unit.

Private companies have two FASB-endorsed alternatives that reduce complexity:

• Amortize goodwill on a straight-line basis over a period not to exceed 10 years (ASC 350-20-35-63 under ASU 2014-02).
• Test for impairment only when triggering events occur, using a more likely than not threshold, rather than conducting mandatory annual quantitative tests.

These private company alternatives significantly reduce the cost of post-acquisition accounting. However, a company that elects the amortization alternative and later becomes public, issues public debt, or is acquired by a public company must retroactively restate its financials to reverse previously recognized amortization. That downstream risk should be weighed at adoption.

GAAP vs. Tax Purchase Price Allocation

A GAAP PPA under ASC 805 is required for financial reporting on every business combination, regardless of deal structure. Tax purchase price allocation follows a different set of rules under the Internal Revenue Code, and the two are not always the same.

For U.S. tax purposes, IRC Section 1060 governs applicable asset acquisitions, requiring consideration to be allocated among seven asset classes using the residual method. Under that method, each class from Class I through Class VI receives value up to its fair market value in order, and whatever consideration remains falls into Class VII as goodwill and going concern value. This allocation determines the tax basis of each acquired asset and therefore the timing and amount of tax deductions available post-closing.

Buyer and seller must each report the agreed allocation on IRS Form 8594, and both parties are required to report the same numbers. A divergence between the two filings is a common audit flag.

In a stock acquisition, the acquirer typically takes the target’s historical tax basis in its assets, and no immediate step-up occurs. However, when the parties make a Section 338(h)(10) election, the transaction is treated as a deemed asset sale for tax purposes while remaining a stock deal legally. This creates a new tax basis equal to the aggregate deemed sale price, allowing the acquirer to depreciate tangible assets and amortize intangible assets over their statutory tax lives, starting fresh.

Under IRC Section 197, goodwill and most other Section 197 intangibles acquired in an asset deal or a 338(h)(10) transaction are amortized over 15 years on a straight-line basis, generating a predictable tax deduction each year. The tax amortization benefit from these deductions is itself incorporated into fair value measurements in the GAAP PPA, because the expected future cash flows from owning an intangible asset are higher when the owner can also deduct the amortization. Valuators call this the tax amortization benefit (TAB) adjustment.

The GAAP PPA and the tax PPA should be coordinated closely. Misalignment creates disclosure complexity and can trigger IRS scrutiny if the tax allocation departs meaningfully from what the GAAP PPA implies about relative asset values.

Common Mistakes in Purchase Price Allocations

Finance teams under pressure to close books quickly frequently run into the same issues:

• Underidentifying intangibles. Assigning too much residual to goodwill rather than recognizing separately valued customer relationships or trade names. This misses deductible amortization and distorts the post-deal earnings picture.
• Using book value proxies instead of fair value. GAAP requires fair value, not historical cost or net book value, for every identifiable asset and liability.
• Treating the measurement period as an extension. The one-year window is for new information about acquisition-date facts, not for completing work that could have been done at closing.
• Ignoring deferred taxes. A PPA creates temporary differences between GAAP carrying values and tax bases. Deferred tax liabilities on stepped-up intangibles, and deferred tax assets on liabilities, must be recognized as part of the allocation and affect the goodwill figure.
• Failing to coordinate with legal and tax counsel. The GAAP PPA and tax PPA should be built in parallel with a shared factual foundation.

Modus’s transaction advisory practice works alongside deal teams from letter of intent through post-close integration, which means the data collection needed for a sound PPA starts well before closing rather than scrambling afterward.

How a PPA Affects Your Audit

For companies subject to audit, the PPA is a focal point. Auditors will scrutinize whether the fair values assigned to identifiable intangibles are supportable, whether the valuation methodology is appropriate for each asset class, whether deferred taxes are correctly computed, and whether required disclosures are complete under ASC 805-10-50. Companies relying on a third-party valuation specialist should expect auditors to assess that specialist’s qualifications, assumptions, and data sources.

Preparing a well-documented PPA, supported by a credentialed independent appraiser, is the single most effective way to reduce friction at the first audit post-acquisition. See Modus’s audit and assurance services for more on how we approach business combination audits.

Frequently Asked Questions

What is purchase price allocation under ASC 805?

Purchase price allocation is the process of assigning the total consideration paid in a business combination to each identifiable asset acquired and liability assumed at fair value, with any remaining excess recognized as goodwill. ASC 805 requires this allocation for every business combination under U.S. GAAP and must be completed, or finalized from provisional amounts, within one year of the acquisition date.

Does purchase price allocation apply to asset deals and stock deals?

Yes, with important differences. GAAP requires a PPA under ASC 805 for any business combination regardless of legal structure. For tax purposes, IRC Section 1060 governs direct asset acquisitions. In a stock acquisition, no tax step-up occurs unless the parties make a Section 338(h)(10) election, which triggers a deemed asset sale treatment for tax purposes while the legal structure remains a stock purchase.

How long does a purchase price allocation take?

The timeline varies with deal complexity. A straightforward acquisition with limited intangibles may take 60 to 90 days after closing. A complex transaction with multiple intangible asset categories, foreign operations, or contingent consideration can extend to the full one-year measurement period. Starting the process at signing rather than at closing meaningfully compresses the timeline.

What is included in goodwill under ASC 805?

Goodwill represents the excess of consideration transferred plus any noncontrolling interest and previously held equity interest fair value over the net fair value of identifiable assets and liabilities. It captures value that cannot be separately recognized, including assembled workforce, synergies, market position, and expected future growth that does not meet the contractual-legal or separability criteria for separate recognition as an intangible asset.

Can private companies amortize goodwill after a purchase price allocation?

Yes. Private companies may elect to amortize goodwill over a period of up to 10 years on a straight-line basis under FASB ASU 2014-02. They may also elect a simplified impairment test triggered only by events that suggest fair value may be below carrying amount, eliminating mandatory annual testing. These alternatives should be evaluated against the possibility of a future IPO, public debt issuance, or acquisition by a public company, all of which require retroactive restatement.

How does a purchase price allocation affect income taxes?

A PPA creates temporary differences between GAAP carrying values and tax bases, requiring recognition of deferred tax liabilities on stepped-up assets and deferred tax assets on assumed liabilities. These deferred taxes affect the goodwill calculation and the post-close tax rate. In asset deals or 338(h)(10) transactions, Section 197 allows a 15-year straight-line amortization deduction for goodwill and most intangibles, which is a meaningful cash tax benefit that should be factored into deal pricing.
