10. LITIGATION

In connection with its business, the Company is from time to time involved in various legal actions. These legal actions may be subject to significant complexities and uncertainties, some of which are beyond the Company’s control, and may allege substantial or indeterminate monetary damages. Based on current information, management does not believe that the ultimate resolution of pending legal matters will have a material adverse effect on the Company’s consolidated financial position or liquidity. However, an adverse outcome in one or more pending legal matters could be material to the Company’s results of operations or cash flows for any particular reporting period.

The Company accrues for loss contingencies when it is both probable that a loss has been incurred and when the amount of the loss can be reasonably estimated. If a loss or additional loss with respect to material legal matters is reasonably possible and the Company is able to estimate the possible loss or range of loss, the Company discloses the estimate of the possible loss or range of loss, if material and as required. However, the Company may be unable to estimate a possible loss or range of loss in some instances based on the significant uncertainties involved in, and/or the preliminary nature of, certain legal matters.
