discuss the indirect consequences of climate-related regulation or

              emissions or are related to carbon-based energy sources;
                increased demand for goods that result in lower emissions than
competing products;
                increased competition to develop innovative new products that
result in lower
              emissions;
                increased demand for generation and transmission of energy from
alternative energy
              sources;
                any anticipated reputational risks resulting from operations or
products that produce
              material greenhouse gas emissions; and
                potential climate-related opportunities, such as developing
ESG-related indices and
              products.
3.       We note your ESG Report identifies physical climate risks for your
largest offices and
         data centers as a potential climate-related risk. Please discuss the
physical effects of
         climate change on your operations and results, such as weather-related
damages to your
         property or operations and weather-related impacts on the cost or
availability of
         insurance. Include quantitative information for each of the periods
covered by your most
         recent Form 10-K and explain whether increased amounts are expected in
future periods.
         In addition, please discuss the potential for indirect weather-related
impacts that have
         affected or may affect your major customers or suppliers.
4.       You reference the purchase of carbon offsets and Renewable Energy
Certificates or
         RECs in your ESG Report. Please provide disclosure about these
purchases and any
         material effects on your business, financial condition, and results of
operations. Provide
         us with quantitative information for each of the periods covered by
your most recent Form
         10-K and the amounts budgeted for or expected to be incurred in future
periods.
        We remind you that the company and its management are responsible for
the accuracy
and adequacy of their disclosures, notwithstanding any review, comments, action
or absence of
action by the staff.
