 In an age of increased and changing risks, we prioritize the strengthening of our corporate governance by enhancing operational structures to integrate and guide our approach to sustainability, creating the right governing bodies and oversight to embed sustainability at the core of our business. We

continue to progress our approach to administering strong governance over the strategic delivery, effective risk management, and assessment of key metrics.

#### Underwriting and Reinsurance Purchasing
Our objective is to create a diversified portfolio of insurance and reinsurance risks, spread across lines of business, products, geographic areas of coverage, cedants and sources. The acceptance of appropriately priced risk is the core of our business. Underwriting requires judgment, based on important assumptions about matters that are inherently unpredictable and beyond our control, and for which historical experience and probability analysis may not provide sufficient guidance. We view underwriting quality and risk management as critical to our success.

#### Underwriting
We underwrite according to the following principles:

• strive to build a diverse portfolio of risk that generates attractive returns by deploying capital in a targeted and efficient manner to deliver enhanced underwriting profitability;

• operate within agreed boundaries as defined by the business plan for the relevant class of business;

• operate within prescribed maximum underwriting authority limits, which we delegate to individual underwriters in accordance with an understanding of each individual underwriter’s capabilities, tailored to the classes of business written by the particular underwriter;

• evaluate the underlying data provided by clients and adjust such data where we believe it does not adequately reflect the underlying exposure;

• price each submission based on our experience in the class of business, and where appropriate, by deploying one or more actuarial models either developed internally or licensed from third-party providers;

• maintain a peer review process to sustain high standards of underwriting discipline and consistency and a sampling methodology for simpler insurance risks;

• engage in peer reviews for more complex risk by several underwriters and input from catastrophe risk management specialists, our team of actuaries and senior management; and

• refer risks outside of agreed underwriting authority limits to the Group Underwriting Committee or relevant entity executive or board of directors as exceptions for approval before we accept the risks.

#### Reinsurance Purchasing
We purchase reinsurance and retrocession to mitigate and diversify our risk exposure to a level consistent with our risk appetite and to increase our insurance and reinsurance underwriting capacity. These agreements provide for recovery of a portion of our losses and loss adjustment expenses from our reinsurers. The amount and type of reinsurance that we purchase
