8. Contingencies

In the normal course of business, the Company is subject to regular examination by various taxing authorities for years not closed by the statute of limitations, including an ongoing customs audit in the United Kingdom in which the Company is contesting audit findings.  The Company accrues a liability for this type of contingency when it believes that it is both probable that a liability has been incurred and that it can reasonably estimate the amount of the loss.  The Company believes that the ultimate outcome of these matters will not have a material adverse impact on the results of operation, liquidity or financial position of the Company. However, if one or more of these examinations has an unfavorable resolution, it is possible that the results of operation, liquidity or financial position of the Company could be materially affected in any particular period.
