Under various federal, state and local environmental laws, a current or previous owner or operator of real property may be liable for the cost of investigating, removing or remediating hazardous or toxic substances on such property. Such laws often impose liability whether or not the owner or operator knew of, or was responsible for, the presence of such hazardous or toxic substances. Even if more than one person may have been responsible for the contamination, each person covered by applicable environmental laws may be held responsible for all of the clean-up costs incurred. In addition, third parties may sue the owner or operator of a site for damages based on personal injury, natural resource or property damage or other costs, including investigation and clean-up costs, resulting from the environmental contamination. The presence of hazardous or toxic substances on one of our properties, or the failure to properly remediate a contaminated property, could give rise to a lien in favor of the government for costs it may incur to address the contamination, or otherwise adversely affect our ability to sell or lease the property or borrow using the property as collateral. Environmental laws also may impose restrictions on the manner in which property may be used or businesses may be operated. A property owner who violates environmental laws may be subject to sanctions which may be enforced by governmental agencies or, in certain circumstances, private parties. In connection with the acquisition and ownership of our properties, we may be exposed to such costs. The cost of defending against environmental claims, of compliance with environmental regulatory requirements or of remediating any contaminated property could materially adversely affect our business, assets or results of operations and, consequently, amounts available for distribution to our stockholders.
Environmental laws in the U.S. also require that owners or operators of buildings containing asbestos properly manage and maintain the asbestos, adequately inform or train those who may come into contact with asbestos and undertake special precautions, including removal or other abatement, in the event that asbestos is disturbed during building renovation or demolition. These laws may impose fines and penalties on building owners or operators who fail to comply with these requirements and may allow third parties to seek recovery from owners or operators for personal injury associated with exposure to asbestos. Some of our properties may contain asbestos-containing building materials.
We invest in properties historically used for industrial, manufacturing and commercial purposes. Some of these properties contain, or may have contained, underground storage tanks for the storage of petroleum products and other hazardous or toxic substances. All of these operations create a potential for the release of petroleum products or other hazardous or toxic substances. Some of our properties may be adjacent to or near other properties that have contained or currently contain underground storage tanks used to store petroleum products or other hazardous or toxic substances. In addition, certain of our properties may be on or are adjacent to or near other properties upon which others, including former owners or tenants of such properties, have engaged, or may in the future engage, in activities that may release petroleum products or other hazardous or toxic substances. As needed, we may obtain environmental insurance policies on commercially reasonable terms that provide coverage for potential environmental liabilities, subject to the policy's coverage conditions and limitations. From time to time, we may acquire properties, or interests in properties, with known adverse environmental conditions where we believe that the environmental liabilities associated with these conditions are quantifiable and that the acquisition will yield a superior risk- adjusted return. In such an instance, we underwrite the costs of environmental investigation, clean-up and monitoring into the cost. Further, in connection with property dispositions, we may agree to remain responsible for, and to bear the cost of, remediating or monitoring certain environmental conditions on the properties.
We generally obtain Phase I environmental site assessments on each property prior to acquiring it and we generally anticipate that the properties that we may acquire in the future may be subject to a Phase I or similar environmental assessment by independent environmental consultants at the time of acquisition. Phase I assessments are intended to discover and evaluate information regarding the environmental condition of the surveyed property and surrounding properties. Phase I assessments generally include a historical review, a public records review, an investigation of the surveyed site and surrounding properties, and preparation and issuance of a written report, but do not include soil sampling or subsurface investigations and typically do not include an asbestos survey. Even if none of our environmental assessments of our properties reveal an environmental liability that we believe would have a material adverse effect on our business, financial condition or results of operations taken as a whole, we cannot give any assurance that such conditions do not exist or may not arise in the future. Material environmental conditions, liabilities or compliance concerns may go undetected by the environmental assessment or arise after the environmental assessment has been completed. Moreover, there can be no assurance that (i) future laws, ordinances or regulations will not impose any material environmental liability or (ii) the environmental condition of our properties will not be affected by tenants, by the condition of land or operations in the vicinity of such properties (such as releases from underground storage tanks), or by third parties unrelated to us.
