Legal and Environmental Matters

In the ordinary course of conducting its business, the Company becomes involved in litigation, administrative proceedings and governmental investigations, including environmental matters.

In the third quarter of fiscal 2015, the Company recorded a $45.5 million benefit as a result of a termination of a contract with a customer and is included in net sales on the Company's consolidated statements of earnings for fiscal 2015.

On September 18, 2008, we were served with a purported class action antitrust lawsuit alleging violations of Section 1 of the Sherman Act, brought by Standard Iron Works of Scranton, Pennsylvania, against nine steel manufacturing companies, including CMC. On March 14, 2014, the Company entered into a final settlement agreement with the plaintiffs. As part of that final settlement, in April 2014, the Company paid approximately $4 million to the plaintiffs in consideration for the full and final release of all claims of the plaintiffs. The Company maintains that the claims lacked merit and that it has full and complete defenses to all of the claims asserted against it. However, the Company agreed to enter into the settlement agreement to avoid further expense, inconvenience, and distraction of burdensome and protracted litigation. On October 17, 2014, the court granted final approval of the settlement.

The Company has received notices from the U.S. Environmental Protection Agency ("EPA") or state agencies with similar responsibility that it is considered a potentially responsible party ("PRP") at several sites, none owned by the Company, and may be obligated under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 ("CERCLA") or similar state statute to conduct remedial investigations, feasibility studies, remediation and/or removal of alleged releases of hazardous substances or to reimburse the EPA for such activities. The Company is involved in litigation or administrative proceedings with regard to several of these sites in which the Company is contesting, or at the appropriate time may contest, its liability at the sites. In addition, the Company has received information requests with regard to other sites which may be under consideration by the EPA as potential CERCLA sites. Some of these environmental matters or other proceedings may result in fines, penalties or judgments being assessed against the Company. At August 31, 2015 and 2014, the Company had $1.0 million and $0.7 million, respectively, accrued for cleanup and remediation costs in connection with CERCLA sites. The estimation process is based on currently available information, which is in many cases preliminary and incomplete. Total environmental liabilities, including CERCLA sites, were $4.3 million and $6.2 million as of August 31, 2015 and 2014, of which $2.4 million and $2.3 million were classified as other long-term liabilities as of August 31, 2015 and 2014. Due to evolving remediation technology, changing regulations, possible third-party contributions, the inherent shortcomings of the estimation process and other factors, amounts accrued could vary significantly from amounts paid. Historically, the amounts the Company has ultimately paid for such remediation activities have not been material.

Management believes that adequate provisions have been made in the Company's consolidated financial statements for the potential impact of these contingencies, and that the outcomes of the suits and proceedings described above, and other miscellaneous litigation and proceedings now pending, will not have a material adverse effect on the business, results of operations or financial condition of the Company.
