    How Does Purchase Price Accounting Work in a Cross-Border Acquisition?

    May 30, 2026

    When a US company acquires a European business, or a European company acquires a US one, the transaction triggers acquisition accounting under ASC 805 (or IFRS 3 if reporting under IFRS). The mechanics are the same regardless of where the acquiree is based, but cross-border deals introduce complications that purely domestic acquisitions do not have: different statutory accounting frameworks, foreign currency, and intangible assets that were never previously recognized on the target’s books.

    The central challenge in cross-border PPA is not just fair value measurement. It is converting the target’s local GAAP opening balance sheet to US GAAP so you have a valid baseline for consolidation. This guide covers both.

    The Basic Mechanics

    Acquisition accounting under ASC 805 requires the acquirer to measure all assets acquired and liabilities assumed at fair value at the acquisition date. This is the opening balance sheet for the acquired business within the consolidated group.

    The difference between the purchase price paid and the net fair value of assets and liabilities recognized is goodwill. Under US GAAP, goodwill is not amortized and is tested for impairment annually. Under IFRS 3, goodwill is also not amortized but tested for impairment. If the target company had already made acquisitions under local GAAP, their existing goodwill will likely be recognized differently (amortized, partially written down, or carried at a different basis). That goodwill becomes part of the fair value baseline you are converting to US GAAP, and must be restated before you measure new goodwill on the acquisition.

    The fair value exercise is the core of PPA. It is also where most of the work sits.

    Converting Local GAAP to US GAAP Before Fair Valuing

    The target’s statutory accounts are denominated in local GAAP. Before you can apply fair value measurement, you need to convert those books to US GAAP. This is a prerequisite step that many acquirers underestimate.

    Common GAAP conversions for European targets include:

    • Revenue recognition. European GAAP often defers revenue differently than ASC 606. Subscription and SaaS businesses in particular may recognize revenue on a different schedule. You need to restate the target’s opening deferred revenue balance to match US GAAP expectations.
    • Capitalization of software and development costs. Many European companies expense internally developed software under local GAAP. Under ASC 985, development costs that meet the capitalization threshold must be capitalized and amortized. The opening balance sheet needs to reflect this.
    • Lease accounting. IFRS 16 and ASC 842 have similar mechanics, but transition dates and grandfathering differ. Right-of-use assets and lease liabilities may need adjustment.
    • Provisions and contingent liabilities. European GAAP often requires provisions for uncertain obligations that US GAAP treats as contingent liabilities disclosed only if probable and measurable. The opening balance sheet liability structure will differ.
    • Pension and post-retirement obligations. IAS 19 and ASC 715 measure these liabilities differently. The opening balance sheet liability must reflect US GAAP measurement.
    • Inventory accounting. LIFO is not permitted under IFRS but is common under US GAAP. If the target uses FIFO under IFRS, no conversion is needed. If it uses weighted average or other methods, ensure consistency with the acquirer’s policy.
    • Goodwill and prior acquisitions. If the target has existing goodwill from prior acquisitions, it may be amortized under local GAAP or carried at a different valuation. Under US GAAP, that goodwill must be derecognized or restated, and the underlying intangible assets of the prior acquisition may need to be identified and valued separately.

    Do not treat the local GAAP opening balance sheet as your PPA starting point. Restate it to US GAAP first. Then apply fair value adjustments on top.

    What Gets Fair Valued (After GAAP Conversion)

    For a European technology or SaaS business, the assets requiring fair value measurement typically include:

    Customer relationships. The value of the existing customer base, measured as the present value of expected future cash flows attributable to those relationships. This is almost always the largest intangible asset in a tech acquisition, and the one auditors spend the most time on.

    Developed technology. The fair value of the software or IP that drives the product. Measured using the relief-from-royalty method (what would you pay to license this technology if you did not own it) or the multi-period excess earnings method.

    Trade names and trademarks. Typically measured using relief-from-royalty. Smaller in tech deals unless the brand carries standalone value.

    Non-compete agreements. If sellers have signed non-competes as part of the deal, these are intangible assets that require fair value measurement and amortization over the non-compete period.

    Deferred revenue. Often the most contentious item in SaaS acquisitions. The acquiree’s deferred revenue (subscription fees received but not yet earned) is marked down to fair value at the acquisition date, which is typically the cost to fulfill the remaining obligation plus a reasonable margin. This creates a permanent revenue reduction in the acquirer’s post-acquisition financials, sometimes called the deferred revenue haircut.

    Contingent consideration. Earnouts based on post-acquisition performance are measured at fair value at the acquisition date and remeasured at each reporting period. The accounting for earnouts is complex and deserves its own treatment.

    The Measurement Period

    ASC 805 allows a measurement period of up to 12 months after the acquisition date to finalize the fair values. During this period, provisional amounts can be adjusted as new information about facts and circumstances that existed at the acquisition date becomes available.

    In practice, most deals target finalizing the PPA within six months. Waiting for the full 12 months creates complexity in interim financial reporting.

    Where Cross-Border Deals Add Complexity

    Currency. The acquisition is recorded in the acquirer’s functional currency. Fair values of assets denominated in the target’s currency are translated at the acquisition-date exchange rate. Post-acquisition, foreign currency translation differences flow through other comprehensive income.

    Deferred tax on intangibles. Intangible assets recognized in PPA create deferred tax liabilities (the book carrying value is higher than the tax basis, since intangibles are often not deductible for local tax purposes). These deferred tax liabilities increase goodwill and require careful calculation.

    Non-deductibility of acquisition costs. Many European jurisdictions do not allow a step-up in basis for acquired intangible assets. The tax basis of customer relationships, developed technology, and trade names may remain zero even though fair value intangibles appear on your balance sheet. This creates a permanent deferred tax liability that sits on the opening balance sheet.

    What Auditors Want to See

    For a PCAOB audit, the PPA needs to be supported by a valuation that uses observable market inputs where available and documents all significant assumptions. The customer relationship valuation model, the revenue attrition assumptions, the discount rate, the royalty rate applied to developed technology: all of these need to be in writing before the audit begins.

    Your GAAP conversion workpaper also needs to be detailed. Show the local GAAP opening balance sheet, document each restatement entry, and reconcile to the US GAAP opening balance sheet. Then show the PPA fair value adjustments on top of that. Auditors will ask for both.

    The documentation can be quite a bit of work for the internal team, but it is also what protects the purchase price allocation from challenge during the audit.
