We engage across the full spectrum of ESG issues, which are relevant to our portfolio holdings, including traditional corporate governance issues such as board diversity and accountability, environmental and social risks and human rights. Initial ESG research and stakeholder engagement helps us identify which companies to engage during the year and we select priorities based on an assessment of the severity and urgency of the issue(s), and their receptiveness to engagement. Our engagement efforts can take a variety of shapes and sizes depending on which tools or methods best fit the task.
Where appropriate we also look to collaborate with coalitions of shareholders and activist organizations. Our collaborative engagements are selected based on a review of the ESG risks and opportunities and the issue's suitability to a wider group of stakeholders. For example, engagements to encourage disclosure are often a good fit for a collaborative approach. Our membership in bodies such as PRI, CDP and ICCR are a big help in forming these coalitions.
One example of our escalation policy was when Mohawk was unresponsive to our letter and subseqent request for dialogue under our Women Empowerment Principles engagement, - We filed a gender board diversity resolution in late 2018, which was subsequently withdrawn in early 2019.
