The S&P Dow Jones and FTSE Russell indices recently took actions designed to exclude companies with multi-class share structures from several of the most prominent market indices.

On July 31st, S&P Dow Jones announced that companies with multi-class share structures will no longer be eligible to be added to the S&P 500, the S&P MidCap 400 or the S&P SmallCap 600. Existing companies included in these indices will not be affected by this change. Companies with multiple share classes or with classes having limited or no voting rights will remain eligible for inclusion in the S&P Global BMI Indices and the S&P Total Market Index.
