Portfolio Environmental Risk Score

The Portfolio Environmental Risk Score is the asset-weighted average of the Company Environmental Risk Scores for the covered corporate holdings in a portfolio. Company Environmental Risk Scores from Sustainalytics measure the degree to which a company’s economic value may be at risk driven by environmental factors.

The environmental risk represents the unmanaged environmental risk exposure after taking into account a company’s management of such risks. The Environmental Risk Scores are displayed as a number between 0 and 100, though most scores range between 0 and 25.
