Risk factors and legal proceedings
Legal proceedings
Due to the nature of our activities, we are at times subject to pending and threatened legal actions that arise out of the ordinary course of business. For information regarding legal proceedings and other claims in which we are involved, see Note 11, Commitments and Contingencies, in the notes to the financial statements included in this Annual Report on Form 10-K. The disposition of any such currently pending or threatened matters is not expected to have a material effect on our business, results of operations or financial condition. However, the results of legal actions cannot be predicted with certainty. Therefore, it is possible that our business, results of operations and financial condition could be materially adversely affected in any particular period by the unfavorable resolution of one or more legal actions. Regardless of the outcome, litigation can have an adverse impact on our business because of defense and settlement costs, diversion of management resources and other factors. In addition, the expense of litigation and the timing of this expense from period to period are difficult to estimate, subject to change and could adversely affect our consolidated financial statements.
