Financial due diligence (“FDD”) is a cornerstone of mergers and acquisitions (“M&A”). Its purpose is to help investors assess the quality of a target company’s earnings, assets, liabilities, working capital, and cash flows before committing to an acquisition.
In a purely domestic transaction, this exercise is usually straightforward. The target group typically prepares its financial statements under one accounting framework, operates within a single tax regime, and answers to one regulatory environment. Commercial risks remain, but the financial information is generally consistent. Cross-border acquisitions are fundamentally different.
Many investment targets today operate through multiple legal entities spanning several jurisdictions. A typical Asian group may comprise a Hong Kong holding company, one or more Mainland Chinese operating subsidiaries, overseas sales companies, procurement entities, and financing vehicles established in different countries. Each entity may prepare its accounts under different accounting standards, follow different tax rules, and operate under different regulatory requirements.
Although these entities ultimately form one consolidated group, their financial information is often far less comparable than investors initially assume. Standard FDD procedures, which focus primarily on validating historical performance and identifying balance sheet risks, may capture only part of the picture. Overseas investors increasingly need a broader review — one that examines whether financial information across the group has been prepared consistently, whether local compliance risks could crystallise after completion, and whether the existing corporate structure remains fit for purpose once ownership changes.
In practice, many of the most significant post-acquisition surprises do not arise from overstated revenue or understated expenses. They stem from inconsistencies between jurisdictions, undocumented accounting practices, unresolved intercompany balances, differing tax treatments, or regulatory obligations that were never fully understood before completion.
Cross-border FDD, therefore, goes beyond verifying historical numbers. It tests whether those numbers present an economically comparable picture of the business across jurisdictions, and whether hidden risks could affect valuation, transaction structure, or post-completion integration.
The article examines the areas that deserve particular attention when overseas investors acquire businesses spanning Mainland China, Hong Kong, and other jurisdictions.
Key Takeaways
- Cross-border FDD must look beyond consolidated figures to test whether financial information is prepared on a consistent basis across jurisdictions.
- Differences in accounting standards, tax systems, and functional currencies can make businesses with identical commercial performance look different on paper.
- Most post-acquisition surprises come from cross-jurisdiction inconsistencies and undocumented practices, not from inflated revenue or hidden costs.
- Investors need advisers who reconcile local statutory accounts, management reporting packages, and consolidated financial statements before relying on group-level figures.
Why Do Cross-Border Transactions Require a Wider Lens?
Many investors assume that if a group prepares consolidated financial statements audited under International Financial Reporting Standards (“IFRS”) or Hong Kong Financial Reporting Standards (“HKFRS”), the financial information is already consistent across the group. In practice, that assumption is only partly true.
Consolidated financial statements are the final output of a reporting process that involves numerous subsidiaries. Each subsidiary first prepares its own local financial statements, which the group then adjusts and consolidates. If the underlying entity-level information is inconsistent, the consolidated figures may look reasonable while masking significant differences in accounting policies, tax treatments, and reporting practices. Cross-border FDD therefore requires advisers to look beyond the consolidated financial statements and understand how the individual pieces fit together.
An experienced FDD team typically seeks answers to questions such as:
- Are financial results prepared on comparable accounting bases across jurisdictions?
- Are local statutory accounts consistent with group reporting packages?
- Have significant accounting adjustments been made only during consolidation?
- Are intercompany balances fully reconciled?
- Are local tax and payroll obligations properly reflected?
- Will the existing structure remain effective after completion?
Each of these questions can shape not only the purchase price but also the acquisition structure, tax planning, financing arrangements, and integration strategy.
Why Do Group Entities Use Different Accounting and Tax Systems?
One of the defining features of cross-border acquisitions is that multiple accounting and tax systems coexist within the same corporate group.
A typical investment structure involving Mainland China may include:
- an overseas parent company reporting under IFRS;
- a Hong Kong intermediate holding or trading company applying HKFRS;
- one or more PRC subsidiaries preparing statutory financial statements under the Chinese Accounting Standards for Business Enterprises (“ASBE”); and
- overseas sales or procurement entities preparing accounts under their respective local GAAP.
From a legal perspective, each entity complies with its own local accounting requirements. From an investor’s perspective, an equally important question arises: are the reported financial results genuinely comparable?
The answer is not always yes. Accounting standards around the world have gradually converged over recent decades, but important differences remain, and even where formal principles are similar, their practical application can differ significantly.
For example, management may recognise revenue differently across jurisdictions. Some subsidiaries may record provisions conservatively, while others adopt more aggressive assumptions. Capitalisation policies for development costs, software, or internally generated assets may vary. Inventory valuation methods may differ, and impairment assessments may vary in rigour from one entity to the next.
As a result, two subsidiaries with identical commercial performance may report materially different profits. Without careful analysis, investors may mistakenly conclude that one business unit significantly outperforms another, when the apparent difference merely reflects differing accounting practices.
How Do Tax Systems Distort Commercial Comparisons
Accounting differences are only one side of the equation. Tax systems also shape how transactions are structured and recorded. The PRC, for instance, operates a comprehensive VAT regime that differs significantly from Hong Kong’s territorial tax system, which imposes no VAT or GST. Certain expenses deductible in one jurisdiction may be non-deductible in another, and timing differences between accounting recognition and tax deductibility vary considerably.
Transfer pricing rules add further complexity. A Mainland manufacturing subsidiary may sell products to a Hong Kong trading company at transfer prices designed to satisfy local tax requirements rather than maximise commercial profitability. Reported profit margins across the group may therefore reflect tax planning considerations rather than underlying operational performance.
Withholding taxes on royalties, service fees, and dividends can also influence where profits accumulate within the group. Cross-border FDD should therefore assess whether reported profitability reflects the existing tax structure rather than underlying commercial economics alone.
After completion, FDD findings may point to areas where the group structure, intercompany arrangements, or reporting processes could be improved. Detailed tax restructuring, transfer pricing redesign, or implementation advice, however, should be handled by professional tax advisers under a separate engagement.
Why Does Functional Currency Matter More Than Investors Expect?
Another frequently overlooked issue is the impact of multiple currencies. Groups operating across Hong Kong, Mainland China, and overseas markets commonly maintain accounting records in HKD, RMB, USD, or other local currencies. Exchange rate fluctuations can significantly affect:
- reported revenue;
- gross margins;
- foreign exchange gains or losses;
- intercompany balances;
- debt covenants; and
- consolidated equity.
An increase in consolidated profit may sometimes reflect favourable currency movements rather than genuine operational improvement. Likewise, substantial foreign exchange gains recognised by one subsidiary may simply offset corresponding losses elsewhere in the group. Experienced FDD teams distinguish between operational performance and translation effects to help investors understand the business’s true earnings capacity.
Why Isn't Local Compliance Enough?
Identifying differences between accounting systems does not necessarily indicate poor financial reporting. Most subsidiaries prepare their accounts in accordance with local legal requirements. The more important question is whether investors can compare financial information across jurisdictions with enough confidence to make an informed investment decision.
Answering that question often requires detailed reconciliation between local statutory accounts, management reporting packages, and consolidated financial statements. This process frequently reveals adjustments that are perfectly legitimate from an accounting perspective but highly relevant to valuation. Examples include:
- group-level consolidation adjustments not reflected in statutory accounts;
- differing depreciation policies across entities;
- inconsistent inventory provisioning;
- varying treatment of government grants;
- different lease accounting approaches; and
- inconsistent recognition of related-party transactions.
Each adjustment may appear immaterial on its own. Collectively, however, they can significantly affect EBITDA, net assets, working capital, and ultimately enterprise value. Cross-border FDD therefore extends beyond checking whether each entity complies with its local accounting standards. Its broader purpose is to determine whether the financial information across the entire group presents a consistent, transparent, and economically meaningful picture — one an overseas investor can confidently rely on when making an acquisition decision.
