Commitments and Contingencies

Legal Proceedings

The Company is from time to time involved in various disputes, lawsuits, warranty claims, environmental and other matters arising in the ordinary course of its business. Management makes assumptions and estimates concerning the likelihood and amount of any potential loss relating to these matters.

The Company currently is a party to various legal proceedings, none of which management expects will have a material adverse effect on the Company’s financial position, results of operations or liquidity. Management accrues a liability for litigation if an unfavorable outcome is determined to be probable and the amount of loss can be reasonably estimated. If an unfavorable outcome is determined by management to be probable and a range of loss can be reasonably estimated, management accrues the best estimate within the range; however, if no amount within the range is a better estimate than any other, the minimum amount within the range is accrued. Legal fees related to litigation are expensed as incurred. Management does not believe that the ultimate outcome of these matters, either individually or in the aggregate, could have a material adverse effect on the Company’s financial position or results of operations; however, litigation is subject to inherent uncertainties.

Under the Company’s leases, tenants are typically obligated to indemnify the Company from and against all liabilities, costs and expenses imposed upon or asserted against it as owner of the properties due to certain matters relating to the operation of the properties by the tenant.
