6.  Litigation and Contingencies

From time to time the Company is subject to certain routine legal proceedings, as well as demands, claims and threatened litigation, that arise in the normal course of its business. The Company believes that the ultimate amount of liability, if any, for any pending claims of any type (either alone or combined) will not materially affect its financial position, results of operations or liquidity.
