Litigation

From time to time, the Company may be a party to litigation, government investigations or regulatory proceedings in the ordinary course of business. Because the results of any litigation or other legal proceedings are uncertain, our financial position, results of operations or cash flows could be materially affected by an unfavorable resolution of one or more of these proceedings, claims, or demands. However, management does not currently believe the ultimate resolution of any pending legal matters is reasonably possible to have a material adverse effect on the Company’s financial position, results of operations or cash flows. The Company accrues for loss contingencies when it is both probable that it will incur the loss and when the Company can reasonably estimate the amount of the loss or range of loss.
