Robeco selects engagement themes in an annual selection process. This process involves our investment teams, our clients and RobecoSAM's sustainability investing research analysts, next to the Active Ownership team. We focus our engagement on long-term, financially material ESG factors that can affect a companies' ability to create value. Achieving impact on the UN Sustainable Development Goals is also an important consideration in our value engagement approach.
We select the companies for engagement based on their exposure to the engagement topic, favoring those companies with the highest exposure for the program. Sector coverage and client holdings are another important factor for case selection. We select three to five new themes every year and on average we include ten companies per engagement theme. Three of Robeco's value engagement themes run continuously, Sound Environmental Management, Sound Social Management and Good Governance. These themes are meant for individual cases on request of portfolio managers or clients, on a topic specific to a certain company, or for following up on voting activities.
In addition, Robeco's enhanced engagement program focuses on companies involved in controversial behavior. This includes companies that severely and structurally breach principles of the United Nations Global Compact in the areas of human rights, labor, environment and anti-corruption, and/or the OECD Guidelines for Multinational Enterprises. In case the engagement is unsuccessful, the respective company will become candidate for exclusion from the investment universe of Robeco.
