Litigation

In the normal course of business, the Company is named as a defendant in various legal proceedings in which claims are asserted against the Company. We record accruals for loss contingencies based on the circumstances of each claim, when it is probable that a loss has been incurred as of the balance sheet date and can be reasonably estimated. Although the outcome of litigation cannot be predicted with certainty, we believe the ultimate resolution of these legal proceedings will not have a material effect on our business or financial condition.
