We participated in our first collaborative engagement in 2015 under the PRI's collaborative engagement on human rights issues in the extractives industry. We are a co-lead for a company. We continued the dialogue with the company in 2016 and carried on in 2017. We plan to use this experience to determine how and when collaborative engagements could be useful. In additional to that, we published a formal engagement policy in 2017. It includes a more structured engagement framework for identifying and prioritizing engagement which encompasses potential collaborative engagements. It is based on quantitative metrics, such as, but not limited to, position size, share register ranking, and qualitative ESG issues. This also informs our process for identifying and prioritising collaborative engagements.
