ISS Releases Updated Factors for QualityScore Governance Rating: New Factors for U.S. Companies Relate to Proxy Access, Board Refreshment and Exclusive Forum Provisions; Data Verification Period Open Until November 11

Sullivan & Cromwell LLP - November 2, 2016

Earlier this week, Institutional Shareholder Services released the details of its updated “QualityScore” corporate governance rating system, previously named the “QuickScore” rating system.

Through 8 p.m. eastern time on November 11, companies may access the underlying data that ISS will use to construct their QualityScore rating through ISS’s website. New scores will then be released on November 21 and begin appearing in ISS research reports.

Because some institutional shareholders may rely, in part, on a company’s corporate governance ratings to make voting and investment decisions, companies may want to consider taking steps to ensure that the information on which these ratings are based is accurate. Information on QualityScore, including the technical document and information on data verification, is available on ISS’s website at
