                                                        disclosure regarding

                                                        offering. Please

                                                        which you performed a

3.    Your response to prior comment 4 states that you did not incur material
capital
      expenditures or compliance costs during fiscal 2020 or fiscal 2021. In
order to better
      understand your response, please tell us about your capital expenditures
and compliance
      costs related to environmental initiatives (including quantification of
amounts
      incurred) and explain how you assessed the materiality of these
expenditures and costs. In
      addition, please tell us more about how you considered providing
disclosure quantifying
      the estimated costs of achieving your carbon neutral goal and explain how
you analyzed
      the materiality of these costs.
4.    Your response to prior comment 5, which states that you do not currently
believe that you
      are subject to material indirect consequences of climate-related
regulations or business
      trends, appears to be conclusory in nature and does not provide an
analysis of the factors
      listed in our comment. Please describe the indirect consequences you
considered in your
      analysis and explain how you concluded they were not material.
5.    Your response to prior comment 6 states that you have not experienced any
material
      physical effects of climate changes on your operations or results. Please
explain whether
      you have experienced physical effects of climate change on your
operations or results and,
      if so, how you concluded that such effects have been, and are expected to
continue to be,
      immaterial to your operations and results. As noted in our prior comment,
quantify
      weather-related damages to your property or operations and discuss any
weather-related
      impacts on the cost or availability of insurance.
