To this end, we use a materiality analysis: to gain insight into the relevance and importance of topics for Boskalis on the one hand, and for our various stakeholder groups on the other. Although material topics remain the same over time, their relevance for both internal and external stakeholders is subject to change. In 2015 we defined our main material themes. These were updated in 2016. In 2017, we once again engaged with our stakeholders to re-assess the most important material CSR themes. By actively engaging with relevant stakeholders at all levels within and outside of our company, we can interact and align our strategy to guide both our business and CSR objectives. More than 70 stakeholders, including the Boskalis Management Board, were consulted for our materiality analysis. A list of relevant topics was drawn up by an independent third party, making use of a longlist of CSR topics based on CSR benchmarks and reporting

frameworks, combined with a media and a peer analysis. This resulted in a new shortlist of 20 relevant topics, including updated and Boskalis-specific definitions. These topics were presented to our stakeholders through an online survey and desk research resulting in 50 valid responses from the 5 stakeholder groups. MATERIALITY ANALYSIS CHANGES Boskalis-specific definitions of the material topics were provided in the shortlist of topics. Topics were divided into the four thematic areas: Care for our people, Impact on local communities, Impact on the environment and Responsible business conduct. Stakeholders were asked to rank and score the topics that mattered to them most. Boskalis management and the Management Board was asked to do the same. The resulting materiality matrix is by definition a snapshot and opinions amongst stakeholder groups may vary. The matrix is a representation of what we understand to be the relative importance of these themes to the company and our stakeholders. The matrix is monitored and revised if and when necessary.
