systems” (Annex VII, Part 4, Paragraph 127). It thus appears that<br />

the two broad functions of model review and model development and<br />

selection could be performed by the same unit. A rationale for this<br />

structure could be found in the skills and experience of people who<br />

design or select models, which sometimes make them the only ones<br />

able to review and validate models. Furthermore, the separation of<br />

the two units could be burdensome, especially in smaller institutions.<br />

364. The coexistence of both functions in the same unit should not be<br />

seen as an obstacle; any potential for lack of objectivity should be<br />

offset with rigorous controls, administered by the Internal Audit, to<br />

prevent bias from affecting the rating process.<br />

3.6.1. Role of the management body<br />

Hierarchy of responsibility/level of decision<br />

365. Sound internal governance requires that the decision­making process<br />

be clearly stated within each institution, in terms of hierarchy and<br />

level of responsibility.<br />

· The management body (both supervisory and management<br />

functions), as the body responsible for policymaking, guidance,<br />

and monitoring of the company’s strategy, should be responsible<br />

for approving all material aspects of the overall Risk Control<br />

System.<br />

· The management body (management function) should ensure<br />

that all components of the IRB system, including controls, are<br />

functioning as intended.<br />

· The credit risk control function is ultimately responsible for proper<br />

functioning of the rating systems; it submits rating systems to<br />

the management body (management function) for approval;<br />

· The Internal Audit should provide an assessment of the overall<br />

adequacy of the internal control system and of the credit risk<br />

control function.<br />

Management body and Senior Management<br />

366. The management body, (both supervisory and management<br />

functions) should be responsible for approving all material aspects of<br />

the overall Risk Control System, including:<br />

· Risk management strategies and policies regarding the internal<br />

rating system (including all material aspects of the rating<br />

assignment and risk parameter estimation processes);<br />

· The organisational structure of the control functions;<br />

· Specifying acceptable risk (using IRB results to define the credit<br />

risk profile of the institution).<br />
