Institutional Shareholder Services Inc. (ISS) is an American proxy advisory firm. Hedge funds, mutual funds and similar organizations that own shares of multiple companies pay ISS to advise (and often vote their shares) regarding share holder votes. As the leading firm in the industry, ISS commands a 48 percent market share as of 2021, with its nearest rival, Glass Lewis, holding a 42 percent market share.
In response to ISS's recommendations to vote against fee-shifting provisions in the event of securities fraud litigation, some have criticized ISS and suggested that it needs to be regulated.
