Commitments and Contingencies

The Corporation utilizes letters of credit in the amount of $14 million to back certain insurance policies and payment obligations.  The letters of credit reflect fair value as a condition of their underlying purpose and are subject to competitively determined fees.

 The Corporation has contingent liabilities which have arisen in the ordinary course of its business, including liabilities relating to pending litigation, environmental remediation, taxes, and other claims.  It is the Corporation's opinion that liabilities, if any, resulting from these matters are not expected to have a material adverse effect on the Corporation's financial condition, cash flows or on the Corporation's quarterly or annual operating results when resolved in a future period.
