Transparency reports for auditors of Nigerian PIEs

Which Nigerian audit firms must publish a yearly transparency report under FRC Rule 12, the four-month deadline, and the quality records to draw it from.

A transparency report is a firm talking about itself in public. For a Nigerian audit firm with public interest entity clients, it is also an annual obligation under the Financial Reporting Council's Rule 12, with a deadline and a step that comes before publication.

Firms that do this well treat the report as the visible end of a year-round process: the quality records they keep anyway become the evidence the report draws on. Firms that do it badly write it from memory in the last fortnight. This article explains who Rule 12 applies to, the timetable it sets, and where the content should come from.

Firms that audit public interest entities

Under FRC Rule 12, audit firms that audit or provide other assurance services to public interest entities must publish a transparency report annually on their website. The Rule was released in April 2023 and is compulsory from January 2023; the first report was required for the firms' 2022 fiscal year-end. The Rule is in the FRC's compilation of its Rules 1 to 14.

The test is the client list, not the size of the firm. A small firm with a single PIE assurance engagement is inside the Rule. Note the breadth of the wording too: "other assurance services" to a PIE count, not only statutory audits. Review the client list for PIE status at least once a year, because a client can move into the category between reporting years.

Lodged first, published within four months

Rule 12 sets an order and a deadline. The firm lodges the report with the FRC first, then publishes it on its website within four months after the end of its reporting year.

A worked timetable for a firm with a December reporting year: the report is drafted in the first quarter, the partner responsible approves it, the firm lodges it with the FRC, and it goes up on the website before the end of April. Working backwards from the four-month limit, the draft should be ready well before the last weeks, because lodging is a step that must come before publication and the firm does not control how quickly any query on it is resolved.

One of the mandatory Rules 9 to 14

In a public notice to statutory auditors dated 24 June 2025, the FRC said strict compliance with its Rules 9 to 14 is mandatory. The notice lists Rule 12, the audit transparency report, alongside Rule 9 on key audit matters, Rule 10 on the statutory audit committee, Rule 11 on the auditor's logo and brand in clients' reports, Rule 13 on non-resident companies and Rule 14 on non-compliance with laws and regulations.

So a missed or late transparency report is not a presentational lapse. It sits in the same group as the Rules that govern what goes into an audit report, which are covered in Rule 14 confirmations and Rule 9 key audit matters.

The quality system behind the report

The content of the report should be read from Rule 12 itself; this article does not restate it. What any firm can say is that a report describing how it manages quality needs a quality system to describe.

IFAC's profile of Nigeria says ISQM 1 and ISQM 2 are applicable and effective in Nigeria for firms performing audits and reviews of financial statements and other assurance engagements. The same profile assesses the quality assurance framework overall as partially adopted, because the FRC's inspection regime for PIEs is not yet fully operational. A firm that has designed and run its ISQM 1 system through the year has most of the raw material for its report already: its policies, its monitoring results, its handling of complaints and its engagement quality reviews. The standards picture is set out in auditing and quality standards in Nigeria and Kenya.

Quality registers and EQR records to draw from

In Achekam, the firm's quality registers, covering professional judgements, quality incidents, complaints and inspection progress, are kept on the server with every version and who changed it. Sign-off roles on professional judgements are checked by the screen, not by the server, so whoever compiles the report should confirm who signed each entry it relies on.

Engagement quality reviews leave a record too. A partner can name an engagement quality reviewer for an engagement, who must be a partner or senior manager not on the engagement team, and that person must clear the audit report before it can be issued. The list of engagements that had a named reviewer, and their clearance, is a factual base the report can draw on rather than a recollection.

The indicators screen with nothing feeding it

One limit should be stated plainly. Achekam's Partner Quality Intervention Centre, which carries an "ISQM 1 / AQI" badge, has no screen that records an indicator value or opens an intervention, and nothing feeds it from the audit file. Three other quality menu entries open the same screen. A firm that wants audit quality indicators in its transparency report must compile them itself, outside that screen.

A yearly routine

1. Confirm at year-end which clients are PIEs and which services the firm provided them.
2. Pull the year's quality register entries and engagement quality review records.
3. Draft against the text of Rule 12, section by section.
4. Have the responsible partner approve the draft.
5. Lodge with the FRC, then publish on the website before the four-month limit.
6. Keep the lodged and published versions together on file.

A report built this way is a by-product of the quality system rather than a separate writing project, which is exactly what it should be.
