Relationship with Internal Auditor

dThe role of the Internal Auditor of an enterprise is determined by the management and its main objective is different from that of external Auditor. Nevertheless, some of the ways of achieving their particular objectives are quite similar and most of the work done and checked by the internal auditor is useful to the external auditor in inspecting and researching the natures, timings and extent of his auditing procedures.
The external Auditor should while auditing, understand and evaluate the functions performed by the internal auditor to the extent he deems that it will be necessary and relevant in understanding the nature, timing and degree of his compliance with, substantive procedures of audit. According to such evaluations, the external auditor might be able to initiate less detailed auditing procedures and methods than would be requried otherwise.

The external auditor’s general researching of the internal audit functions will help the auditor in determining the degree to which he can rely upon the work and books prepared by the internal auditor. The external auditor should document his evaluations and conclusions in this matter.

Coordination with the internal auditors is needed by the external auditor while auditing and this coordination is generally has a greater effect when meetings are held at pre-decided, and appropriate intervals during the calendar  year. External auditors should have access to the internal audit reportings that are relevant and be kept informed of any significant matter which has come to the internal auditors attentions and which the auditor believes might affect the books and work of the external auditors. Similarly the external auditors should  coney information and inform the internal auditors of any important matters which might affect his work. Both the auditors need to work in tandem.

Where after  evaluating the work of the internal auditor, the external auditors decides to rely upon specificwork of internal auditors as a basis for modifying the nature, timings and extent of his auditing procedures, he must review the internal auditor’s work and the conclusions arrived at must be documented in writing. The External auditor should test check the work of the internal auditor on which he intends to rely.
