NOTE 14. COMMITMENTS AND CONTINGENCIES

Purchase Obligations

The Company regularly enters into future purchase commitments for materials, supplies, services and fixed assets related to ongoing operations. Approximately 75% of these purchase obligations are for inventory items to be sold in the ordinary course of business. Purchase obligations include all enforceable, legally binding agreements to purchase goods or services that specify all significant terms, regardless of the duration of the agreement. Agreements with variable terms are excluded because we are unable to estimate the minimum amounts. Another significant obligation relates to capital expenditures. We do not expect potential payments under these provisions to materially affect results of operations or financial condition based upon reasonably likely outcomes derived by reference to experience and current business plans.

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. See Note 19, Commitments and Contingencies, to the audited consolidated financial statements in the Company's Annual Report on Form 10-K for the fiscal year ended August 31, 2016.

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 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 both February 28, 2017 and August 31, 2016, the Company had accrued $0.7 million 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 with respect to CERCLA sites, were $3.2 million and $3.3 million as of February 28, 2017 and August 31, 2016, respectively, of which $2.1 million was classified as other long-term liabilities as of both February 28, 2017 and August 31, 2016. These amounts have not been discounted to their present values. 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 unaudited condensed 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.
