Explanation:
The Advanced Internal Ratings-Based (A-IRB) Approach under Basel II is best suited for banks with diversified asset portfolios seeking a precise and tailored assessment of their risk exposure in CAR calculations. This approach allows banks to use their internal models for calculating all risk components, including Probability of Default (PD), Loss Given Default (LGD), Exposure at Default (EAD), and Effective Maturity (M). A-IRB is more complex and requires banks to have sophisticated risk assessment models and extensive historical data. It provides a more accurate reflection of a bank’s risk profile and is typically adopted by larger, more complex financial institutions with advanced risk management capabilities.
A is incorrect because the Standardized Approach uses prescribed risk weights set by regulatory authorities, offering less precision and customization for banks with diverse asset portfolios.
B is incorrect because the Advanced Measurement Approach pertains to the calculation of operational risk, not credit risk for CAR purposes.
