US GAAP Accounting Advisory Firm vs In-House Teams

TL;DR:

• Companies incorporated in the US must convert to US GAAP for SEC-regulated financial reporting. Those listing through a foreign entity may maintain their financials under MFRS or IFRS, or convert to US GAAP voluntarily. Either way, the 2 frameworks diverge materially.
• ASC 606 and ASC 842 are among the most frequently cited areas in SEC comment letters, and misapplication can delay registration statements.
• In-house teams are well-positioned for local compliance but typically require significant investment to extend their capability to US GAAP SEC filings.
• A specialised US GAAP accounting advisory firm is most commonly engaged at IPO preparation, SEC registration, and ongoing PCAOB audit support stages.
• The right structure depends on a company’s filing obligations, internal technical capacity, and progress of its US capital market journey.

US Generally Accepted Accounting Principles (US GAAP) is the accounting framework required by the SEC for domestic US companies filing financial statements as part of a registration statement or ongoing public company reporting. Foreign issuers, including Malaysian companies listing through a foreign incorporated entity, are not universally required to adopt US GAAP; they may file under International Financial Reporting Standards (IFRS) or their home country equivalent, such as Malaysian Financial Reporting Standards (MFRS), subject to SEC acceptance. 

Malaysian companies that engage with US capital markets must therefore understand a reporting framework that may be materially distinct from the one they apply domestically. 

US GAAP and MFRS diverge materially in how specific transactions are measured, recognised, and disclosed, and those differences carry direct compliance consequences for SEC financial reporting in Malaysia.

For companies evaluating how to structure their US GAAP reporting function, the choice between an in-house accounting team and a specialised US GAAP accounting advisory firm involves considerations of technical scope, regulatory risk, and resourcing that are specific to each company’s capital market objectives.

How US GAAP Differs From MFRS and IFRS

MFRS vs US GAAP differences are most consequential where the 2 frameworks apply different measurement and recognition principles to the same underlying transaction. US GAAP is more rules-based and prescriptive, providing detailed application guidance for specific transaction types. IFRS relies more on principles-based judgement.

For Malaysian companies undertaking an IFRS to US GAAP conversion, the most significant divergences typically arise in revenue recognition and lease accounting. Both are areas of sustained SEC regulatory focus, requiring careful accounting judgement during the conversion process.

The table below summarises the primary areas of divergence relevant to first-time US GAAP filers:

Area	US GAAP Standard	IFRS Equivalent	Key Divergence
Revenue recognition	ASC 606	IFRS 15	Performance obligations, principal vs agent, variable consideration
Lease accounting	ASC 842	IFRS 16	Lease definition and embedded lease identification
Income taxes	ASC 740	IAS 12	Recognition of uncertain tax positions
Financial instruments	ASC 815 / ASC 820	IFRS 9 / IFRS 13	Classification and measurement

Structuring US GAAP Reporting: In-House Teams and Advisory Firms

How should a Malaysian company structure its US GAAP reporting function, and what does each approach involve?

In-house accounting teams are generally well-positioned for MFRS compliance, management reporting, and Bursa-related obligations. Extending that capability to cover SEC financial reporting in Malaysia requires sustained investment in technical training and recruitment of professionals with SEC filing experience.

Specialised US GAAP accounting advisory firms provide technical accounting support on an engagement basis, which allows companies to access US GAAP guidance at the points in their lifecycle where it is most needed.

Many companies use a combination of both, with internal teams managing local reporting and advisory firms providing US GAAP compliance support at critical filing milestones.

Is your accounting function ready for US GAAP reporting?
Companies approaching a US IPO or managing ongoing SEC filing obligations benefit from an early assessment of their US GAAP readiness. Speaking with an experienced advisory firm at this stage helps identify technical gaps, estimate conversion timelines, and structure the right support before the registration process begins.

Circumstances Where External US GAAP Advisory Support Is Engaged

US IPO preparation and SEC registration. Companies preparing for a US IPO are required to file financial statements with the SEC as part of a registration statement, audited by a Public Company Accounting Oversight Board (PCAOB)-registered firm. Domestic US companies must present those statements under US GAAP. Foreign issuers may present under IFRS or an accepted home-country standard such as MFRS, though many elect to convert to US GAAP. This process typically involves an IFRS to US GAAP conversion where applicable, requiring technical accounting positions to be documented and reviewed before submission.

Ongoing SEC reporting obligations. Annual filings such as Form 10-K and quarterly disclosures on Form 10-Q are filed by domestic US companies and require US GAAP. Form 20-F, used by foreign issuers including Malaysian companies, may be prepared under US GAAP, IFRS, or MFRS, depending on the issuer’s circumstances. Companies without the relevant expertise internally frequently engage a US GAAP accounting advisory firm to support their periodic reporting cycle alongside the PCAOB audit process. 

US GAAP readiness assessments. Companies evaluating a US listing but not yet in the formal process engage an advisory firm to review existing accounting policies, identify areas requiring significant US GAAP judgement, and estimate the resources required for conversion. This is typically the first point at which Malaysian companies seek external US GAAP guidance.

The Role of Hexcellence Consulting

Hexcellence Consulting provides US GAAP advisory services to Malaysian companies engaged in US capital market activity, including IPO preparation, SEC registration, and ongoing PCAOB audit support. The firm’s advisory work covers technical accounting positions, accounting policy documentation, and IFRS to US GAAP conversion from MFRS.

Hexcellence operates as a member of the OTC Markets Premium Provider Directory and has supported Malaysian companies through US capital market listings and SEC filing processes. Its advisory services are structured to complement the existing finance function rather than replace it, with engagements calibrated to each client’s specific filing obligations and timeline. The firm also provides SEC reporting support and ongoing listing regulatory advisory services alongside its US GAAP practice.

Key Considerations for Malaysian Companies

The decision between in-house accounting teams and a specialised US GAAP accounting advisory firm is relevant at each stage of a Malaysian company’s engagement with US capital markets, from initial conversion through to ongoing SEC reporting. 

US GAAP compliance requires a level of technical specificity that extends well beyond routine MFRS reporting. For companies approaching a US IPO or managing ongoing SEC obligations, structured advisory support reduces the regulatory risk that arises when those gaps are left unaddressed.

Companies evaluating their US GAAP reporting structure are encouraged to discuss their specific circumstances with a US GAAP accounting advisory firm experienced in cross-border financial reporting. Hexcellence Consulting is available to assist Malaysian companies in assessing their US GAAP readiness and identifying the advisory support most relevant to their reporting obligations.
