### Investment Operations
Our investment strategy is focused on delivering stable investment income and total return through all market cycles while maintaining appropriate portfolio liquidity and credit quality to meet the requirements of our customers, rating agencies and regulators. To enhance investment returns where possible, we tactically adjust the duration of the investment portfolio and asset allocation taking into account the average liability duration of our reinsurance and insurance risks and our views of interest rates, the yield curve, credit spreads and markets for different assets.

As at December 31, 2024, we maintained an Asset and Liability Management Committee, which reports into the Group Executive Committee. The Group Chief Investment Officer is a voting member of the Asset and Liability Management Committee and provides updates as appropriate to the Group Investment Committee of the Board at its regular meetings, which in turn reports up to the Board. The primary purpose of the Asset and Liability Management Committee is to oversee the management of the Company’s asset and liability management framework, including in

relation to interest rate, liquidity, foreign exchange, credit and inflation risks across its assets and liabilities, as well as the development of, and monitoring the adherence to, associated policies and procedures, and review of key assumptions relating to the Company’s investment strategy underpinning the development of the Company’s annual business plan as might impact asset and liability outcomes, in collaboration with other business functions.

The investment guidelines set by each entity’s board specify minimum criteria on the overall credit quality and liquidity characteristics of the portfolio, and include limitations on the size of certain holdings and restrictions on purchasing certain types of securities.
