Contingencies	Contingencies Litigation In the normal course of our business, various claims and lawsuits have been filed or are pending against us.

Contingent Obligations – Indemnifications Some of the debt contracts we enter into include indemnification provisions obligating us to make payments to the counterparty if certain events occur. These contingencies generally relate to changes in taxes or changes in laws which increase our lender’s costs. The indemnification clauses are often standard contractual terms and were entered into in the normal course of business. There are no stated or notional amounts included in the indemnification clauses, and we are not able to estimate the maximum potential amount of future payments, if any, under these indemnification clauses.
