There may be known or unknown environmental liabilities associated with properties we previously owned, currently own, or may acquire in the future. Under various federal, state, and local laws and regulations relating to the environment, as a current or former owner or operator of real property, we may be liable for costs and damages resulting from environmental matters, including the presence or discharge of hazardous or toxic substances, waste, asbestos-containing building materials, or petroleum products at, on, in, under or migrating from such property, including costs to investigate or clean up such contamination and liability for personal injury, property damage, or harm to natural resources. Such laws often impose liability without regard to whether the owner or operator knew of, or was responsible for, the presence of such contamination. These costs and damages could be substantial. Certain uses of some properties may have a heightened risk of environmental liability because of the hazardous materials used in performing services on those properties, such as industrial properties or businesses using petroleum products, paint, machine solvents, and other hazardous materials. We typically undertake customary environmental diligence prior to our acquisition of any property, including obtaining Phase I environmental site assessments. The Phase I environmental site assessments are limited in scope and therefore may not reveal all environmental conditions affecting a property. Therefore, there could be undiscovered environmental liabilities on the properties we own.
The known or potential presence of hazardous substances on a property may adversely affect our ability to sell, lease, or improve the property, or to borrow using the property as collateral. In addition, environmental laws may create liens on contaminated properties in favor of the government for damages and costs it incurs to address such contamination. Moreover, if contamination is discovered on our properties, environmental laws may impose restrictions on the manner in which they may be used or which businesses may be operated, and these restrictions may require substantial expenditures.
Although we may obtain insurance for environmental liability for certain properties that are deemed to warrant coverage, our insurance may be insufficient to address any particular environmental situation and we may be unable to continue to obtain insurance for environmental matters, at a reasonable cost or at all, in the future. If our environmental liability insurance is inadequate, we may become subject to material losses for environmental liabilities. Our ability to receive the benefits of any environmental liability insurance policy will depend on the financial stability of our insurance company and the position it takes with respect to our insurance policies.
Although our leases generally require our tenants to operate in compliance with all applicable federal, state, and local environmental laws, ordinances, and regulations, and to indemnify us against any environmental liabilities arising from the tenants' activities on the property, we could nevertheless be subject to liability, as a current or previous owner of real estate, including strict liability, by virtue of our ownership interest and may be required to remove or remediate hazardous or toxic substances on, under, or in a property. Further, there can be no assurance that our tenants, or the guarantor of a lease, could or would satisfy their indemnification obligations under their leases.
