Anyone who has closed the books on a Franco-American group knows the frustration of reconciling numbers that simply do not match. The source of the friction is the gap between US GAAP and the French PCG: the PCG is designed to satisfy tax authorities, while US GAAP aims to reflect economic reality for investors.
1. Inventory valuation: the LIFO problem
Inventory is often the largest line on the balance sheet — and one of the first places the two systems diverge in ways that compound.
The incompatibility of LIFO
Some US companies still use Last-In, First-Out (LIFO) for tax advantages. LIFO is strictly prohibited under the French PCG and IFRS. If your French subsidiary is consolidated into a US parent using LIFO, a manual adjustment is required every period.
Hidden acquisition costs
French books often default to simplified costs. US GAAP (ASC 330) requires including freight-in, customs duties, and insurance. If these costs aren't capitalized, the French subsidiary's margins look artificially high and consolidated statements become inaccurate.
The solution: standardize the group on FIFO or Weighted Average Cost. Both are acceptable under French and US standards and eliminate an entire category of month-end reconciliation work.
2. Fixed assets: tax rules vs. economic reality
French depreciation is largely driven by tax law — a computer is written off over three years because that's what the tax code permits. US GAAP ignores tax incentives and requires depreciation based on the actual economic useful life of the asset.
The challenge of componentization
French rules often require componentization: breaking a building into parts (roof, HVAC, structure) with their own timelines. If your French subsidiary skips it while your US consolidation assumes it has been done, asset values will be wrong.
The solution: maintain a dual fixed asset register. One "legal" register for French tax filings, one parallel "economic" register for US GAAP reporting.
3. Systems: reducing audit risk
Many mid-sized companies manage the gap through manual top-side adjustments in spreadsheets. Those entries sit outside the formal ledger, making them hard to audit and easy to get wrong.
Impairment testing risks
Under US GAAP (ASC 360), impairment testing relies on projected future cash flows. If your French subsidiary's data isn't structured to provide them, you can't run the test properly — leaving you exposed during audits or due diligence.
The solution: invest in multi-book accounting capability. Modern ERPs or accounting middleware book a transaction once and automatically categorize it for both PCG and US GAAP.
Conclusion: visibility is the goal
The gap between French and US accounting for physical assets is primarily a visibility problem. To gain clarity:
Bridge these gaps and a month-end close that used to take weeks becomes a streamlined process your leadership can trust.
