Commitments and Contingencies
 
We are subject from time to time to various legal proceedings and claims that arise during the ordinary course of our business. We do not believe that the outcome of those "routine" legal matters should have a material adverse effect on our consolidated financial position, operating results or cash flows; however, we can provide no assurances that legal claims that
may
arise in the future will not have such a material impact on the Company.
