What is purchase price allocation? A complete guide for acquirers

When you acquire a business, the purchase price you paid must be allocated across the identifiable assets and liabilities of the acquired company. This process (purchase price allocation) is not optional, and getting it right has lasting consequences for your financial statements, tax position, and post-acquisition reporting.

What is purchase price allocation?

Purchase price allocation (PPA) is the process of assigning the total consideration paid in a business acquisition to the individual assets acquired and liabilities assumed, in accordance with applicable accounting standards. It is required for every business combination (whether structured as a share purchase, an asset acquisition, or a merger) and it must be completed within the measurement period following the acquisition close. 

The result of the PPA is a fair value balance sheet for the acquired business as of the acquisition date. Every asset (tangible and intangible) and every liability is measured at its fair value on that date. The difference between the total consideration paid and the net fair value of the identifiable assets and liabilities is recorded as goodwill.

PPA is governed by two primary accounting standards, depending on where the acquirer reports:

• ASC 805 - Business Combinations (US GAAP): applies to companies reporting under US Generally Accepted Accounting Principles, including US-listed companies and their subsidiaries. The most widely applied standard for US acquirers
• IFRS 3 - Business Combinations: applies to companies reporting under International Financial Reporting Standards, including companies listed in the EU, UK, India, the Middle East, and most other markets. 

PPA is not optional. Under both ASC 805 and IFRS 3, a purchase price allocation is required for every transaction that meets the definition of a business combination. It is not a discretionary exercise and it is not something that can be deferred to a convenient time - the measurement period begins at the acquisition date and has a maximum duration of 12 months.

Why is purchase price allocation required?

PPA exists for a fundamental reason: the purchase price paid in an acquisition almost always differs (sometimes significantly) from the book value of the acquired company's net assets as reported in its historical financial statements. Historical book values reflect the historical cost of assets, often years or decades ago, and do not capture the current fair value of intangible assets that have been built up over time but never appeared on the balance sheet.

Without PPA, an acquirer could pay $200M for a company whose book value is $50M and simply record $150M as goodwill, a catch-all figure that obscures the true composition of the acquired value. PPA forces the acquirer (with the support of independent valuation professionals) to identify and quantify every component of value, including:

• Customer relationships and contracts that generate future revenue
• Technology, software, and intellectual property developed by the acquired company
• Trade names, brands, and trademarks with commercial value
• Non-compete agreements with departing employees or sellers
• Favorable or unfavorable leases and contracts
• In-process research and development not yet commercialized

Only after all identifiable intangible assets have been recognized at fair value does the goodwill represent a legitimate accounting figure. Goodwill is not simply "overpayment", it reflects synergies; assembled workforce; and other economic benefits that cannot be individually identified and measured. But it should be residual, not dominant.

The four components of a purchase price allocation

Every PPA engagement involves four analytical steps, each of which requires professional judgment and is subject to auditor review.

Step 1: Determine the consideration transferred

The total purchase price (cash, stock, assumed liabilities, contingent consideration, and earnouts) must be measured at fair value on the acquisition date. Earnouts in particular require independent fair value measurement using probability-weighted models.

Step 2: Identify and value tangible assets and liabilities

All tangible assets (property, plant, equipment, inventory, receivables) and all assumed liabilities are remeasured at acquisition-date fair value, which may differ significantly from book value.

Step 3: Identify and value intangible assets

The most analytically intensive step. All identifiable intangible assets (customer relationships, technology, trade names, non-competes) must be identified and valued using income, market, or cost approaches. This is the core of the valuation firm's work.

Step 4: Calculate and record goodwill

Goodwill is the residual - the consideration transferred less the net fair value of all identified assets and liabilities. The appraiser to ensure that the goodwill is genuinely residual and not a catch-all for value that should have been attributed to specific intangibles.

What is identified in a purchase price allocation?

The intangible asset identification step is where PPA delivers its most significant analytical value and where the most judgment is required. Under both ASC 805 and IFRS 3, an intangible assets must be recognized separately from goodwill if it meets one of two criteria: it is separable (capable of being sold, transferred, or licensed independently) or it arises from contractual or legal rights. 

The most commonly identified intangible assets in business combinations are:

• Customer relationships - 

    the value of existing customer contracts and the expectation of repeat business from established customer relationships. Typically the largest intangible asset identified in service and technology acquisitions. For more on how these are valued, see Valuing Customer Relationships in Purchase Price Allocation

• Developed technology -

    software, algorithms, proprietary processes, and technical know-how that the acquired company has developed and uses in its products or services. For more on technology asset valuation, see Valuing Technology and IP Assets in M&A Transactions

• Trade names and trademarks -

    the brand value of the acquired business, recognized where the trade name generates a commercial premium above generic alternatives

• Non-compete agreements -

    contractual restrictions on key employees or sellers from competing with the acquirer, which have value to the extent they protect the acquired revenue base

• In-process research and development (IPR&D) -

    research programmes that have not yet reached commercialization, particularly significant in pharmaceutical, biotech, and technology acquisitions

• Favorable contracts and leases -

    contracts with terms more favorable than market, which represent an economic advantage over the remaining contract term

Goodwill vs identifiable intangibles. A common outcome of inadequate PPA work is over-allocation to goodwill, recording value as goodwill that should have been identified and measured as a specific intangible asset. This matters because identifiable intangibles are amortized over their useful lives (typically 3 to 15 years), which affects post-acquisition earnings, while goodwill treatment differs by standard. The distinction has lasting financial statement consequences. For a deeper treatment, see Goodwill vs Identifiable Intangible Assets in Business Combinations.

How the purchase price allocation process works

A PPA engagement typically follows a structured process from engagement initiation to final report delivery. Understanding the process helps acquirers plan effectively and avoid the most common causes of delay and audit friction.

1. Engagement initiation and document request

   : The valuation firm requests the acquisition agreement, financial statements, projections, customer data, technology documentation, and any pre-deal due diligence materials. The quality and completeness of these materials directly affects the quality and timeliness of the PPA

2. Management interviews

   : The valuation team interviews management of the acquired business to understand its operations, customer relationships, technology assets, and competitive position. These interviews are essential for identifying intangible assets that are not visible in financial statements

3. Intangible asset identification

   : Based on the documents and interviews, the valuation firm identifies all intangible assets that meet the ASC 805 or IFRS 3 recognition criteria. Any asset that is separable or arises from contractual rights must be recognized, regardless of whether it appeared on the acquired company's balance sheet

4. Valuation modelling

   : Each identified intangible asset is valued using the most appropriate methodology: the multi-period excess earnings method for customer relationships, the relief from royalty method for trade names and technology, or the cost approach for assembled workforce and certain other assets.

5. Goodwill calculation and reasonableness check

   : Once all identifiable assets and liabilities have been valued, goodwill is calculated as the residual. The valuation firm assesses whether the goodwill amount makes economic sense in the context of the acquisition rationale.

6. Draft report and auditor review

   : The draft PPA report is delivered to the acquirer and reviewed by auditors. The auditor's review of the PPA methodology and assumptions is typically the most scrutinised step in the post-acquisition financial reporting process. 

Common purchase price allocation mistakes acquirers make

The most consequential PPA mistakes are almost always made before the valuation firm is engaged, in the decisions about timing, scope, and provider selection.

• Commissioning the PPA too late

  : The measurement period begins at the acquisition date. Waiting until months after close to engage a valuation firm compresses the available time and increases the risk of audit complications. The PPA should ideally be initiated within weeks of closing

• Treating PPA as a compliance exercise rather than a value identification exercise

  : An acquirer that approaches PPA purely as a box-checking exercise is likely to end up with a low-quality report that over-allocates to goodwill and understates identifiable intangibles with lasting consequences for financial reporting and tax

• Underestimating the intangible asset scope

  : Many acquirers are surprised by the number and value of intangible assets identified in a rigorous PPA. A business that appears to have primarily tangible assets often has significant customer relationship, technology, or brand value that must be recognized. 

• Selecting a provider without sector experience

  : PPA methodology is general, but its application varies significantly by sector. A SaaS acquisition requires different comparable data and different modelling assumptions than a pharma or financial services acquisition. Appraiser sector experience directly affects the quality of the result

Key Takeaways

• Purchase price allocation is required for every business combination under ASC 805 (US GAAP) and IFRS 3 (international). It is not optional and must be completed within 12 months of the acquisition date
• PPA assigns the total consideration paid to identifiable assets and liabilities at fair value, only the residual is recorded as goodwill
• Intangible assets (customer relationships, technology, trade names, non-competes) are the most analytically complex component of PPA and are frequently under identified in low-quality engagements
• The values assigned in the PPA drive post-acquisition amortization charges that affect reported earnings and EBITDA for years after the deal closes
• Over-allocation to goodwill, by failing to identify intangible assets, creates a larger goodwill balance subject to future impairment and distorts the post-acquisition financial picture
• The PPA should be initiated within weeks of closing to avoid measurement period complications and audit friction

Frequently Asked Questions

What is purchase price allocation in M&A?

Purchase price allocation (PPA) is the process of assigning the total consideration paid in an acquisition to the individual assets acquired and liabilities assumed, each measured at fair value on the acquisition date. It is required under ASC 805 (US GAAP) and IFRS 3 (international standards) for every business combination. The difference between the consideration paid and the net fair value of identified assets and liabilities is recorded as goodwill.

When is a purchase price allocation required?

A PPA is required for every transaction that meets the definition of a business combination under ASC 805 or IFRS 3 - including share purchases, asset acquisitions, and mergers where the acquirer obtains control of a business. The measurement period begins at the acquisition date and has a maximum duration of 12 months. 

Who performs a purchase price allocation?

A PPA is performed by a qualified independent valuation firm with experience in business combination accounting and intangible asset valuation. The acquirer's auditors review the PPA but do not perform it - the valuation firm and the auditor have distinct and independent roles. 

How long does a purchase price allocation take?

A standard PPA engagement typically takes 4 to 6 weeks from engagement initiation to final report delivery, depending on the complexity of the acquisition and the availability of management and financial data. 

What is the difference between ASC 805 and IFRS 3?

Both standards require fair value measurement of assets and liabilities in a business combination, but they differ in several important ways - including the treatment of non-controlling interests, goodwill measurement, and the recognition criteria for certain contingent liabilities.
