OUR REPORT'S STAKEHOLDER and strategy FOCUS

The aim of our integrated reporting suite is to enable our stakeholders, including capital providers, to make an informed assessment of Gold Fields' long-term sustainability and ability to create enduring value. We embrace integrated thinking, and by structuring our 2020 IAR around our strategic pillars we concisely and transparently articulate how our material matters, risks and opportunities, operating environment, performance and prospects unlock value for stakeholders.

In compiling this IAR, we complied with the Global Reporting Initiative (GRI) Standards: Core option and the International Integrated Reporting Council's (IIRC's) International Framework. As detailed on our AFR., we have also aligned this report with a range of additional codes, frameworks and standards, including the King IV Report on Corporate Governance for South Africa 2016 (King IVTM1). On occasion, we use non-International Financial Reporting Standards (IFRS) measures in the IAR, as defined on the AFR.
