NOTE M— COMMITMENTS AND CONTINGENCIES

Litigation

The Company may be involved in litigation incidental to the operation of the business. The Company intends to vigorously defend all matters in which the Company is named as defendant and, for insurable losses, maintain significant levels of insurance to protect against adverse judgments, claims or assessments that may affect the Company. Although the adequacy of existing insurance coverage of the outcome of any legal proceedings cannot be predicted with certainty, based on the current information available, the Company does not believe the ultimate liability associated with known claims or litigation, if any, in which the Company is involved will materially affect the Company’s condensed consolidated financial condition or results of operations.
