(5)A single officer with overall responsibility for the safeguarding of client instruments and funds should be appointed in order to reduce risks of fragmented responsibility across diverse departments, especially in large and complex firms, and to remedy unsatisfactory situations where firms do not have overarching sight of their means of meeting their obligations. The single officer should possess sufficient skills and authority in order to discharge duties effectively and without impediment, including the duty to report to the firm's senior management in respect of oversight of the effectiveness of the firm's compliance with the safeguarding of client assets requirements. The appointment of a single officer should not preclude that officer from carrying out additional roles where this does not prevent the officer from discharging the duties for safeguarding client financial instruments and funds effectively.
