This document discusses challenges in risk data aggregation and internal risk reporting practices. It notes issues such as mapping entities and instruments across different identification systems, obtaining real-time risk information, and distinguishing between country risk and sovereign risk. The presentation provides examples to illustrate these challenges, such as showing how the same company can have multiple IDs, how credit default swap prices can signal credit risk differently than ratings, and how country risk does not always mirror sovereign risk. It emphasizes the importance of effective mapping and reporting practices for comprehensive risk management.
