The professional standard NEP 705, in its revised version applicable to fiscal years opening from January 1, 2026, frames the formulation of modified opinions expressed by the statutory auditor. This revision aligns the Tunisian framework with international requirements (revised ISA 705).
Three types of modified opinion. The standard clearly distinguishes: qualified opinion (significant but not pervasive impact), adverse opinion (significant and pervasive impact), and disclaimer of opinion (inability to obtain sufficient evidence). The boundary between these three cases is now further codified.
Dedicated section in the report. Any modified opinion must be the subject of a dedicated section titled "Basis for the modified opinion", immediately after the "Opinion" section. This section precisely describes the elements at the origin of the modification, their quantified and qualitative impact.
Impact on governance. Listed companies and consolidated groups will note a more formalised dialogue with their auditors in case of disagreement. The standard explicitly provides for consultation of the audit committee before any modified opinion. For unlisted family groups, the spirit of the standard nevertheless calls for systematic escalation to the board of directors.
Our reading. In practice, this revision does not revolutionise the auditor's mission — it clarifies it. Finance directors will gain by anticipating friction zones (estimates, impairment, going concern) ahead of closing, rather than discovering the topic upon reading the draft report.
