Explanation

Both I and II are correct characteristics of a strong risk data aggregation capability.

I. Produce aggregate risk information on a timely basis - This aligns with the timeliness principle from the Basel Committee, which requires that risk information be available when needed for decision-making.

II. Capture and aggregate all material risk data - This aligns with the completeness principle from the Basel Committee, which requires that institutions capture data on their entire universe of material risk exposures.

Key characteristics of strong risk data aggregation:

• Completeness: Capture all material risk data
• Timeliness: Provide information when needed
• Accuracy: Ensure data reliability
• Adaptability: Accommodate changing business needs
• Integrity: Maintain data consistency and reliability

Both statements represent fundamental requirements for effective risk data aggregation systems according to regulatory standards and best practices.
