G4-18 Process for defining report content

IAMGOLD has presented information in this report that the Company regards as material to its operations and stakeholders. Material issues are those considered to be consistent with IAMGOLD’s Health and Safety Policy and its Sustainability Policy. They also take into account the issues raised by our stakeholders.

At both the corporate and site level, IAMGOLD continually assesses what issues are material to its stakeholders. Included in this group are IAMGOLD employees, communities, governments and other impacted or interested parties.

Our management systems, including our risk management process, identify aspects that present a material risk to an operation or the Company. These are prioritized to prevent accidents, impacts on the environment, and incidents that may involve communities or other stakeholders.

The sustainability department within each IAMGOLD site undertakes its own materiality process in both formal and informal ways, but primarily through discussion with stakeholders, and continuous updating of risk registers, stakeholder maps, grievance registers and other consultation documents. Similar exercises are conducted at the corporate office and include strategic planning reviews of stakeholder comments to determine material issues on short-, medium- and long-term bases.

Data has been provided on operations for which IAMGOLD is the owner-operator: Westwood, Essakane and Rosebel. The health, safety and sustainability performance of our joint venture interests in Sadiola and Yatela is covered by the AngloGold Ashanti Sustainability Report at anglogoldashanti.com/sustainability/reports.

Information is provided where feasible for exploration offices, and we are working on closing information gaps going forward where data is not currently being tracked.

G4-19 Priorities identified IAMGOLD continues to work toward achieving our Zero Harm commitment. Please view our Targets and Achievements page for 2017 objectives and our President's Message for an overview of 2016.

Stakeholder Engagement
G4-24 List of stakeholder groups IAMGOLD has thousands of stakeholders. At our projects and operations, our priority stakeholders include, but are not limited to, our employees, our host communities, civil society organizations and both local and national governments. At the corporate level, we share many of the same types of stakeholders, but we also interact regularly with shareholders and our own Board of Directors.
G4-25 Basis for identifying and selecting stakeholders We encourage our sites to take an inclusive approach to stakeholder identification, and to cast a wide net. The identification process is an ongoing exercise in which stakeholders are directly involved. We also encourage our sites to pay extra attention to vulnerable groups that may be excluded from traditional forms of engagement. Each year we engage with thousands of local, regional and national level stakeholders in the countries where we operate.
G4-26 Approach to stakeholder engagement, topics raised through stakeholder engagement and organization’s response to key topics and concerns

Our engagement approach is unique to every site. The frequency and intensity of our meetings depends on the local, regional and national stakeholder context. While each site has the flexibility to design its own engagement program, guidance is provided at the corporate level through various documents, which include:

Overall, our engagement is guided by principles of honesty and transparency, and by the construction of meaningful relationships. Engagement is done on both an ad hoc and a systematic basis. We respond to incoming questions from communities, civil society, investment firms and others, but we also have management systems that set out ongoing engagement schedules, track meetings and measure the general satisfaction of our engagement. We meet with stakeholders in formal settings, like the Annual General Meeting, community open houses or in scheduled meetings with community consultation committees. We also take advantage of less formal opportunities such as individual consultations and community “walkabouts”.
