Guarantees, Commitments and Contingencies
The Corporation utilizes letters of credit in the amount of $9 million to back certain financing instruments, insurance policies and payment obligations.  The Corporation utilizes trade letters of credit and bankers' acceptances in the amount of $4 million to guarantee certain payments to overseas suppliers. The letters of credit reflect fair value as a condition of their underlying purpose and are subject to fees competitively determined.



Withdrawal Liability From Multi-employer Pension
On February 2, 2017, the Corporation was notified of a withdrawal liability from a multi-employer pension fund associated with a business sold by the Corporation as a going concern in 2013. The business subsequently ceased operations, triggering the liability for which it was responsible. The trustee of the pension fund has asserted a claim against the Corporation as a prior indirect owner of the business. The Corporation has not recorded any liability associated with this claim because it believes the likelihood of an unfavorable outcome is neither probable nor remote. The Corporation believes it has strong legal and factual defenses, and intends to vigorously defend itself against this claim.

Other Litigation
The Corporation is involved in various kinds of disputes and legal proceedings that have arisen in the course of its business, including pending litigation, environmental remediation, taxes and other claims.  It is the Corporation’s opinion, after consultation with legal counsel, that additional liabilities, if any, resulting from these matters are not expected to have a material adverse effect on the Corporation’s quarterly or annual operating results and cash flows when resolved in a future period.
