Commitments and Contingencies.

(15) Commitments and Contingencies. MSC is a party to various legal proceedings in connection with the remediation of certain environmental matters. The Company’s environmental accruals were approximately $1.3 million as of November 30, 2011, and $1.3 million as of February 28, 2011. Management does not believe that the outcome of its environmental legal proceedings will have a material adverse effect on its financial statements, given the accruals recorded as of November 30, 2011, and, where applicable, taking into account contributions from other PRPs. There are, however, a number of uncertainties. These include, without limitation, the cost of site cleanup, the discretionary authority of federal and state regulatory authorities in bringing enforcement actions and other factors that could affect the Company’s exposure.

The Company is also a party to various legal actions and customer disputes arising in the ordinary course of its business. These legal actions and customer disputes cover a broad variety of claims spanning MSC’s entire business. We believe that the resolution of these legal actions and customer disputes will not, individually or in the aggregate, have a material adverse effect on its financial statements.
