Certain requirements in this Module indirectly extend to auditors, by virtue of their appointment by investment firm licensees. Auditors appointed by investment firm licensees must be independent (cf. Sections AA-1.4 and AA-1.5). Auditors who resign or are otherwise removed from office are required to inform the CBB in writing of the reasons for the termination of their appointment (cf. Sections AA-1.2). Other requirements are contained in Sections AA-1.3 (Audit partner rotation) and AA-3.1 (Auditor reports).
