The significant influence functions, which are specified in SUP 10.4.1 R, comprise the governing functions (see SUP 10.6), the required functions (see SUP 10.7), the systems and controls function1 (see SUP 10.8) and the significant management functions (see SUP 10.9). SUP 10.5 applies to each of the significant influence functions.1
the appointment is to provide cover for an approved person whose absence is:
the appointment is for less than 12 weeks in a consecutive 12 month period;
the description of the relevant significant influence function does not relate to those activities of that individual.
SUP 10.5.5 R enables cover to be given for, say, holidays and emergencies and avoids the need for the precautionary approval of, for example, a deputy. However, as soon as it becomes apparent that a person will be performing a controlled function for more than 12 weeks, the firm should apply for approval.
