      • Do you agree with S&P DJI’s definition of MegaCap company as any company whose total market capitalization is within the top 100 largest in the S&P TMI? Or should the definition be any company whose total market capitalization is within the top 50 largest?
      • Do you agree with the proposal to shorten the IPO Seasoning requirement to six months from 12 months for the S&P 500, S&P MidCap 400, and S&P SmallCap 600?
      • Do you agree with the proposal to exempt MegaCap companies from the 0.10 minimum IWF eligibility requirement for the S&P 500?
      • Do you agree with the proposal that a company determined to be a MegaCap company as of the evaluation date does not need to pass the Financial Viability criteria to be eligible?

      • Do you have any feedback regarding S&P DJI’s proposal to implement float increases after the end of the MegaCap IPO lock-up period gradually or in tranches depending on company-specific details?
