The level or type of involvement in, or amount of revenue earned from, certain activities or business segments that lead to exclusion by FTSE can vary from one activity or business segment to another.The Index methodology also excludes the stocks of companies that, as FTSE determines based on its internal assessment, do not meet certain labor, human rights, environmental, and anti-corruption standards as defined by the United Nations Global Compact Principles, as well as companies that fail to meet two of the following three diversity criteria: (1) at least one woman on the board; (2) diversity policies in place; and (3) diversity management systems in place. FTSE uses internal methodologies to analyze various factors in determining whether a company meets the foregoing criteria and/or falls within a particular industry, including whether the company has a certain amount of revenue derived from an industry, the company’s level of involvement in an industry, and the severity of certain controversies (as determined by FTSE), which can vary from one company to another and from one activity to another.
