This is the first Global Reporting Initiative (GRI)-compliant report for DTE Energy, covering calendar year 2013. GRI is a voluntary, international framework that provides guidance to organizations on non-financial reporting. DTE Energy utilizes the G4 guidance, published in 2013, to help us craft our communications about corporate citizenship programs and performance. We conducted a materiality analysis to identify those issues that are significant for our company, and the content of our report reflects those priorities. In accordance with the GRI guidelines, we also discuss stakeholder engagement and how we interact with our stakeholders -- including employees, investors, customers and neighbors -- around environmental and social topics.
