Contingency

One of our consolidated subsidiaries is currently engaged in a commercial dispute with a third party that relates to circumstances that arose prior to September 30, 2014. Subsequent to September 30, 2014, we acquired additional information regarding this matter, and, under generally accepted accounting principles, we have recorded $5.9 million in other expenses during the three months ended September 30, 2014 to establish a provision for our current estimate of our maximum exposure for this contingency. However, we will continue asserting our rights under the contract. We believe these negotiations, when complete, will result in a substantial reduction of the liability. Because negotiations are ongoing, the outcome of those negotiations and the net amount for which our subsidiary will ultimately be liable are uncertain.
