Effective governance is a crucial principle of an effective capital adequacy process. It necessitates the board and senior management's effective oversight of the capital adequacy process. This includes periodic reviews of the BHC's risk infrastructure and loss- and resource-estimation methodologies. It also involves the evaluation of capital goals, the assessment of the appropriateness of stressful scenarios considered, regular reviews of any limitations and uncertainties in all aspects of the Capital Adequacy Process (CAP), and the approval of capital decisions. In the case of Campbell bank, the lack of review of its risk infrastructure and loss-estimation methodologies for over a year indicates a violation of the principle of effective governance.

Choice A is incorrect. Robust internal controls refer to the systems and procedures put in place to ensure the integrity of financial and accounting information, meet operational and profitability targets, and achieve compliance with laws, regulations, and policies. While regular reviews of risk infrastructure could be part of a robust internal control system, it is not directly related to the scenario described.

Choice B is incorrect. Sound foundational risk management refers to having a solid base for identifying, assessing, managing, monitoring and reporting risks. Although reviewing risk infrastructure can be part of this process, it does not necessarily mean that if Campbell bank has not undergone a review for over a year its foundational risk management is unsound.
