In 2016, we continued our training around the nature and materiality of ES risks, and the tools available to apply the ES Policy Framework. We trained approximately 500 selected employees in the US and Asia. The training specifically addressed the topic of human rights and the UK Modern Slavery Act, protection of World Heritage Sites, and climate protection. In 2017, we will follow our Group-wide rollout plan to cover Europe, the Middle East, and Africa.
The insight of non-governmental organizations (NGOs) is a valuable contributor to our approach to evaluate environmental and societal trends and issues, and their implications on the financial sector. In 2016, NGOs continued to scrutinize our performance on ES issues and we received more than 40 requests for information (mostly in writing) around potential client relationships and/or projects, as well as wider criticism concerning our approach to themes such as climate change, deforestation, and human rights.
We carefully assess all requests, pubic reports and Web-based rankings mentioning our business. Although we are not able to comment on existing or potential client relationships, in most cases we provide a response, either in writing or in direct dialog, of which a number of engagements took place in 2016.
