Commitments and Contingencies

Note 14—Contingencies

We are subject to various lawsuits and claims in the normal course of business. In addition, from time to time, we receive communications from government or regulatory agencies concerning investigations or allegations of non-compliance with laws or regulations in jurisdictions in which we operate. Although the ultimate outcome of such lawsuits, claims and investigations cannot be ascertained, we believe, on the basis of present information, that the disposition or ultimate resolution of such claims, lawsuits and/or investigations will not have a material adverse effect on our business, results of operations or financial condition. We establish specific liabilities in connection with regulatory and legal actions that we deem to be probable and estimable, and we believe that our reserves for such liabilities are adequate.
