The Company is a party to certain claims and legal actions generally incidental to its business. For certain divestiture transactions completed in prior years, the Company has agreed to indemnify the buyer for various liabilities that may arise after the disposal date, subject to limits of time and amount. The Company is a party to certain claims made under these indemnification provisions. As of December 31, 2017, the Company has a contingent liability recorded for such provisions related to discontinued operations. Management does not believe that the outcome of this claim, or other claims which are not clearly determinable at the present time, would significantly affect the Company's financial condition or results of operation.
