ISA 450 misstatement evaluation in France: NEP 450 (Norme d'Exercice Professionnel)

France has adopted ISA through the Normes d'Exercice Professionnel (NEP), issued by the Compagnie Nationale des Commissaires aux Comptes (CNCC) and approved by the H3C. NEP 450 transposes ISA 450 into the French regulatory framework, and French commissaires aux comptes (statutory auditors) apply it within a system that has several distinctive features: the legal mandate of the commissaire aux comptes is broader than in many other jurisdictions, joint audits are mandatory for certain entities, and the French accounting framework (Plan Comptable Général) has specific features that affect misstatement identification. The French audit is a legal mission (mission légale) with responsibilities defined by the Code de Commerce, which adds a compliance dimension to the ISA 450 evaluation that goes beyond financial statement accuracy. The H3C (Haut Conseil du Commissariat aux Comptes) is France's audit regulator, responsible for oversight of all commissaires aux comptes but with direct inspection authority over PIE audits. The H3C was reformed in 2016 to align with EU Audit Regulation requirements and again in 2023 when it was absorbed into the new Haute Autorité de l'Audit (H2A). The regulatory body conducts annual inspections and publishes findings that identify areas where audit quality needs improvement. Misstatement evaluation has appeared in H3C/H2A reports as an area requiring better documentation and more rigorous evaluation.

Regulatory context: Haut Conseil du Commissariat aux Comptes (H3C)

The H3C's inspection reports have identified specific deficiencies in how French auditors apply NEP 450. Common findings include: the misstatement schedule being completed at the end of the audit but not updated throughout fieldwork as misstatements are identified; the clearly trivial threshold not being documented in the audit strategy; and the ISA 450.11 evaluation consisting of a simple calculation comparing the aggregate to materiality without qualitative analysis. The H3C has emphasised that the evaluation must consider the nature and cause of misstatements, not just their amount. The CNCC has published technical guidance (avis techniques) on materiality and misstatement evaluation that supplements NEP 450. These guidelines address specific French accounting topics, including the evaluation of misstatements in the Plan Comptable Général accounts (which form the basis for tax computation), the treatment of provisions réglementées (regulated provisions specific to French GAAP), and the assessment of misstatements in the annexe (notes to the financial statements). French auditors should consult the CNCC's guidance in addition to the NEP itself.

Practical guidance for France

French practitioners working in a joint audit environment need to coordinate the misstatement schedule with their co-commissaire aux comptes. In a joint audit, each auditor performs procedures on their allocated sections and identifies misstatements within their scope. The two auditors must then share their misstatement schedules and perform the ISA 450.11 evaluation jointly on the combined aggregate. This requires a documented protocol for sharing misstatement information, agreeing on materiality levels (which should be consistent between the two firms), and reaching a joint conclusion on whether uncorrected misstatements are material. The tracker supports multi-auditor schedules with separate columns for each firm's findings and a combined total. For entities reporting under French GAAP (Plan Comptable Général), certain accounting treatments unique to France create misstatement categories that do not exist under IFRS. Provisions réglementées (such as provisions pour hausse des prix and amortissements dérogatoires) are tax-driven entries permitted under French GAAP but with no IFRS equivalent. These provisions affect the balance sheet and income statement, and errors in their calculation are misstatements under NEP 450. For entities preparing both French GAAP and IFRS accounts, these provisions are eliminated in the IFRS adjustments, so a misstatement in a provision réglementée affects only the French GAAP financial statements.

Audit expectations

H3C/H2A inspectors expect to see a complete misstatement schedule that covers both the comptes annuels (statutory accounts) and, where applicable, the comptes consolidés (consolidated accounts). For joint audits, the schedule should identify which firm identified each misstatement and confirm that both firms agreed on the categorisation and evaluation. The ISA 450.12 communication in France goes to the conseil d'administration or the comité d'audit, and the H3C expects this communication to be specific enough that the governance body can make an informed decision about each uncorrected item. French audit mandates are fixed-term (six years for non-PIEs, renewable; six years for PIEs, with mandatory rotation). At the start of a new mandate, the incoming auditor should obtain the predecessor's most recent misstatement schedule and consider whether prior-year uncorrected misstatements affect opening balances. The H3C has noted that this transition is often handled poorly, with incoming auditors failing to request or review the predecessor's ISA 450 documentation.

France-specific considerations

The French tax system's connection to the statutory accounts creates significant ISA 450 implications. Corporate income tax (impôt sur les sociétés) is calculated from the résultat fiscal, which starts with the résultat comptable from the statutory accounts and applies tax adjustments. An uncorrected misstatement that affects the résultat comptable flows directly into the tax base. French auditors should quantify the tax effect of each uncorrected misstatement and communicate it as a qualitative factor. For entities in the French intégration fiscale (tax consolidation) regime, the effect spreads across the group. The French commissaire aux comptes has a specific legal obligation to report certain matters to the procureur de la République (public prosecutor) under Article L.823-12 of the Code de Commerce. While misstatements per se are not reportable, facts that suggest fraud are. If the pattern of misstatements identified during the audit suggests intentional manipulation (for example, consistent overstatement of revenue through premature recognition), the commissaire must consider whether the obligation to report is triggered. This legal obligation adds weight to the qualitative evaluation under NEP 450. French entities listed on Euronext Paris must also comply with AMF (Autorité des Marchés Financiers) requirements for financial reporting. The AMF reviews published financial statements and can require corrections. If the AMF identifies a misstatement that the auditor had accumulated but not required to be corrected, the auditor's judgment in concluding that the misstatement was not material comes under scrutiny. This creates an additional incentive for French auditors to push for correction of borderline items rather than accepting them as uncorrected.

Common inspection findings

The misstatement schedule was prepared at the end of the audit rather than updated throughout fieldwork, resulting in items being omitted because they were not recalled at the completion stage.

In joint audits, the two firms did not share their respective misstatement findings before performing the ISA 450.11 evaluation, so the aggregate evaluation was based on incomplete information.

Provisions réglementées calculation errors were identified but not recorded on the misstatement schedule because the auditor incorrectly treated them as tax matters outside the scope of the financial statement audit.

The clearly trivial threshold was not documented in the audit strategy, making it impossible for the inspector to assess whether misstatements had been correctly filtered.

The qualitative evaluation of uncorrected misstatements did not consider the effect on the résultat fiscal or on distributable reserves under French company law.
