Whilst in an ideal world, Trustees would have the time to review internal control systems for themselves, this is rarely likely to be practicable (or desirable!) and you will need to place reliance on other parties to obtain the assurance that you need.
There are several levels of assurance that can be obtained:
1. Self assurance by management
Annual certificates can be prepared by scheme management outlining the internal control systems that they are responsible for and how they ensure these are working as expected. Although there is a lack of independent verification in this method.
2. Assurance from third parties
Trustees should ask for and review AAF 1/06 reports (previously known as FRAG 21 reports) from their investment managers, custodians and administrators.
These will outline the internal control regimes in place at these third parties. Where such reports are not produced, the Trustees should be questioning that fact.
All schemes, regardless of size, should be requesting these reports, although it must be noted that these reports are best practice and not scheme specific.
3. Assurance from your external auditors
Your external auditors will have a good understanding of your scheme’s internal financial controls for the purposes of their statutory audit.
Trustees could therefore consider requesting that their external auditor agrees a separate engagement to specifically target certain areas of internal financial control to be tested each year.
More detailed testing, outside the scope of the statutory audit, will provide further assurance on key areas, however the scheme auditor needs to be careful not to cross ethical boundaries and compromise their independence.
4. Assurance from an independent firm
For larger schemes, Trustees should seriously consider appointing an independent firm as internal auditors to provide them with assurance on the entire system of internal controls.
This service will be totally independent, should review all areas of high risk each year, and other risk areas on a cyclical basis as appropriate.
The internal audit service will report to Audit Committee meetings and should produce an annual report with an overall opinion on the state of the system of internal control.
Where the Company has an Internal Audit department, the Trustees can seek their involvement with the agreement of the Company, however, very often, the Company Internal Audit department lack the resources and pensions expertise to carry out a detailed review of the scheme’s internal controls.
