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.

On September 18, 2008, the Company was 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. The lawsuit, filed in the United States District Court for the Northern District of Illinois, alleged that the defendants conspired to fix, raise, maintain and stabilize the price at which steel products were sold in the United States by artificially restricting the supply of such steel products. The lawsuit, which purported to be brought on behalf of a class consisting of all parties who purchased steel products directly from the defendants between January 1, 2005 and September 2008 (collectively, the "Direct Purchaser Plaintiffs"), sought treble damages and costs, including reasonable attorney fees and pre- and post-judgment interest.

On March 14, 2014, the Company entered into a final settlement agreement with the Direct Purchaser Plaintiffs. As part of that final settlement, in April 2014, the Company paid approximately $4.0 million to the Direct Purchaser Plaintiffs in consideration for the full and final release of all claims of the Direct Purchaser 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.

Since the filing of the direct purchaser lawsuit, a case has been filed in federal court in the Northern District of Illinois on behalf of a purported class of indirect purchasers in approximately 28 states naming the same defendants and containing allegations substantially identical to those of the Standard Iron Works complaint. That case has in effect been stayed. Another indirect purchaser action was filed in Tennessee state court, again naming the same defendants but contending that the conspiracy continued through 2010. The case has been removed to federal court, and plaintiffs have moved to remand. The motion to remand has not yet been decided, and no motion practice or discovery has taken place. The Company believes that the lawsuits are without merit and plans to defend them vigorously. Due to the uncertainty and the information available as of the date of these financial statements, the Company cannot reasonably estimate a range of loss relating to these cases.

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, 2014 and 2013, the Company had $0.7 million and $0.9 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 $6.2 million and $9.0 million as of August 31, 2014 and 2013, of which $2.3 million and $5.0 million were classified as other long-term liabilities as of August 31, 2014 and 2013. 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.

Guarantees

During fiscal 2012, the Company entered into a guarantee agreement with a bank in connection with a credit facility granted by the bank to a supplier of the Company. The fair value of the guarantee is negligible. The maximum credit facility with the bank was $4.0 million, and the Company had no exposure as of August 31, 2014. The Company's maximum exposure was $3.5 million as of August 31, 2013.
