As of June 30, 2025 and December 31, 2024, our conditional asset retirement obligations liability primarily consisted of the soil

and groundwater remediation liabilities associated with certain of our properties. Some of our properties may contain asbestos or may

be subjected to other hazardous or toxic substances, which, under certain conditions, requires remediation. We engage independent

environmental consultants to conduct Phase I or similar environmental assessments at our properties. This type of assessment

generally includes a site inspection, interviews, and a public records review; asbestos, lead-based paint, and mold surveys; subsurface

sampling; and other testing. We recognize a liability for the fair value of a conditional asset retirement obligation (including asbestos)

when the fair value of the liability can be reasonably estimated. In addition, environmental laws and regulations subject our tenants, and

potentially us, to liability that may result from our tenants’ routine handling of hazardous substances and wastes as part of their

operations at our properties. These assessments and investigations of our properties have not to date revealed any additional

environmental liability we believe would have a material adverse effect on our business and financial statements or that would require
