This report includes disclosures following the frameworks of the Sustainability Accounting Standards Board Standards and Task Force on Climate- Related Financial Disclosure Recommendations. In our use of certain terms from these frameworks, we are not endorsing or adopting such terms or the definitions thereof as used in one or more of the frameworks. We are not obligating ourselves to use such terms in the ways defined by or used in the frameworks, and we make no representation or warranty as to any such use or definition in the frameworks.
