Key takeaways
- Purchase price allocation assigns the total price paid for a business to its individual assets and liabilities at fair value, with any excess recorded as goodwill.
- In Hong Kong, purchase price allocation is required under HKFRS 3 for business combinations, and the way you allocate the price can affect future tax deductions and depreciation allowances.
- The process involves identifying and valuing net identifiable assets, recording fair value adjustments, and calculating goodwill, typically with help from a valuation expert.
- You have up to 12 months after the acquisition to finalise the purchase price allocation, allowing time to gather accurate information and refine estimates.
What is purchase price allocation?
Purchase price allocation (PPA) is the process of assigning the total price paid for an acquired business to its individual assets and liabilities at fair value. Any amount paid above the fair value of net identifiable assets is recorded as goodwill.
When you acquire a business in Hong Kong, purchase price allocation helps you break down what you actually bought. This process ensures your balance sheet accurately reflects the value of each asset and liability. Under HKFRS 3, purchase price allocation is mandatory for business combinations in Hong Kong.
Why purchase price allocation matters
Purchase price allocation affects how an acquisition appears in your financial records and influences decisions long after the deal closes.
Financial clarity
Allocating the purchase price gives you a clear picture of what each part of the acquired business is worth. This helps you track performance, plan depreciation schedules, and report accurate figures to stakeholders.
Tax and allowances
How you allocate the purchase price can affect future tax deductions and depreciation allowances. For example, allocating more value to depreciable assets may increase your allowable deductions over time. Always check with your accountant to understand the tax implications for your specific situation, as the Inland Revenue Department has specific rules on allowable deductions.
Strategic planning
Understanding the fair value of acquired assets helps you make informed decisions about resource allocation, future investments, and potential disposals. You can identify which assets add the most value and which may need attention.
Regulatory compliance
Purchase price allocation is required under HKFRS 3, the Hong Kong standard for business combinations issued by the Hong Kong Institute of Certified Public Accountants (HKICPA). This standard is converged with IFRS 3, meaning your financial reporting aligns with international practices.
How purchase price allocation works
The purchase price allocation process follows a structured approach to ensure fair values are accurately determined and recorded.
1. Identify and value net identifiable assets
Start by listing all assets and liabilities the business holds. Then determine the fair value of each item using valuation approaches: market (comparing to similar items sold), income (based on expected future cash flows), or cost (what it would cost to replace). A valuation expert typically performs this work, especially for complex items like intellectual property or specialised equipment.
2. Record fair value adjustments
Fair value adjustments capture the difference between what assets are carried at on the seller's books and their actual fair value. A write-up increases value; a write-down decreases it. For example, if a property is carried at HK$200,000 but valued at HK$280,000, you record an HK$80,000 write-up. These adjustments can also create deferred tax assets or liabilities because the tax base can differ from the new carrying amount.
3. Calculate goodwill
Goodwill equals the purchase price minus net identifiable assets. If you paid HK$500,000 for a business with net identifiable assets worth HK$350,000, goodwill is HK$150,000. You have a measurement period of up to 12 months after the acquisition date to finalise these figures.

Key components of purchase price allocation
Several elements make up the purchase price allocation, each requiring careful consideration.
Net identifiable assets
Net identifiable assets include all assets and liabilities that can be separately identified and measured. This covers tangible items like equipment and property, as well as intangible items that meet recognition criteria. The total is calculated as identifiable assets minus assumed liabilities.
Fair value adjustments
Fair value adjustments bring each asset and liability to its current market value at the acquisition date. These adjustments affect depreciation and amortisation going forward, as the new carrying amounts form the basis for future expense calculations.
Intangible assets
Intangible assets often represent significant value in an acquisition. Common examples include customer relationships, trade names, non-compete agreements, proprietary software, and patents. Note that an assembled workforce is not recognised separately under HKFRS 3; its value sits within goodwill.
Goodwill
Goodwill is the residual amount after allocating the purchase price to all identifiable assets and liabilities. It represents factors like reputation, customer loyalty, and synergies that cannot be separately identified. Goodwill is not amortised but is tested for impairment annually under Hong Kong accounting standards.
Purchase price allocation example
Here is how purchase price allocation works in practice using a Hong Kong landscaping business.
You buy a landscaping business for HK$500,000. After valuation, the tangible assets at fair value are:
- Workshop: HK$329,000
- Truck: HK$25,000
- Trailer: HK$8,000
- Mower: HK$3,000
- Two mowers: HK$2,000 each
- Miscellaneous tools: HK$1,000
Total tangible assets: HK$370,000
The business also has liabilities:
- Warranty obligations: HK$20,000
Net identifiable assets: HK$370,000 – HK$20,000 = HK$350,000
Goodwill: HK$500,000 – HK$350,000 = HK$150,000
The formula in words: purchase price minus net identifiable assets equals goodwill. These figures appear on your financial statements after the acquisition closes.
Share purchase vs asset purchase
When acquiring a business, you typically choose between two deal structures: share purchase or asset purchase.
Share purchase
In a share purchase, you buy the seller's shares in the company. You take on the whole entity, including its assets, liabilities, contracts, and history. You still complete purchase price allocation on consolidation to recognise the fair value of what you acquired. Tax consequences differ from an asset purchase, so check with your accountant before deciding.
Asset purchase
In an asset purchase, you buy specific assets and assume specific liabilities, leaving the legal entity with the seller. This structure is more common in small business deals because it lets you choose exactly what you take on. The purchase price allocation process is essentially the same, but tax treatment differs. Talk to your accountant about which structure suits your situation.
Common challenges in purchase price allocation
Several issues can complicate the purchase price allocation process.
- Valuing intangible assets that lack an active market
- Estimating fair value accurately when comparable data is limited
- Setting useful lives for amortisation of acquired intangibles
- Aligning tax and accounting treatment across different bases
- Gathering complete and reliable data from the acquired business
Accounting standards for purchase price allocation
Understanding the relevant standards helps ensure your purchase price allocation meets regulatory requirements.
HKFRS 3 (Business Combinations)
HKFRS 3 is the Hong Kong standard issued by the HKICPA that governs how businesses account for acquisitions. It requires you to recognise identifiable assets and liabilities at fair value on the acquisition date. Any excess of the purchase price over net identifiable assets is recorded as goodwill. The standard also specifies disclosure requirements about the acquisition.
International standards (IFRS 3)
HKFRS 3 is converged with IFRS 3, the international equivalent. This means Hong Kong financial statements prepared under HKFRS are comparable with those prepared under IFRS globally. Smaller qualifying entities in Hong Kong may use the SME-FRF and SME-FRS reporting option, which has simplified requirements for certain transactions.
The measurement period
You have up to 12 months from the acquisition date to finalise your purchase price allocation. During this measurement period, you can adjust provisional amounts as new information becomes available. After 12 months, any changes are treated as corrections rather than measurement period adjustments.
Goodwill impairment testing
Goodwill is not amortised under Hong Kong accounting standards. Instead, you test it for impairment at least annually under HKAS 36. If the carrying amount exceeds the recoverable amount, you recognise an impairment loss.

FAQs on purchase price allocation
Here are answers to common questions about purchase price allocation.
When is purchase price allocation required?
Purchase price allocation is required whenever one business acquires another and accounts for it as a business combination under HKFRS 3 or IFRS 3. It applies to both share purchases and asset purchases that meet the definition of a business combination.
Who performs purchase price allocation?
Typically, a valuation expert or specialist firm performs the detailed valuation work. Your accountant then uses these valuations to prepare the accounting entries and disclosures.
What is the purchase price allocation formula?
Purchase price minus fair value of net identifiable assets equals goodwill. If the result is negative, you have a bargain purchase rather than goodwill.
What happens if the purchase price is less than net assets?
This is called a bargain purchase. Under HKFRS 3 and IFRS 3, the excess of net identifiable assets over the purchase price is recognised as a gain in profit or loss.
How long does the purchase price allocation process take?
The measurement period allows up to 12 months from the acquisition date to finalise the allocation. Complex acquisitions with many intangible assets or uncertain valuations often use most of this time.
Can you amend a purchase price allocation after it's finalised?
After the 12-month measurement period closes, you cannot adjust the original allocation retrospectively. Any corrections are treated as errors and accounted for in the period they are identified.
