Contingencies and Commitments [Abstract]
CONTINGENCIES AND COMMITMENTS	NOTE 6 - CONTINGENCIES AND COMMITMENTS With respect to the matters described in Note 14, Contingencies and Commitments, to the Company’s consolidated financial statements included in the 2010 Form 10-K and as updated in Note 6, Contingencies and Commitments, in the Company’s condensed consolidated financial statements included on Form 10-Q for the first and second quarters of fiscal year 2011, under the heading Federal Securities Class Actions, Shareholder Derivative Lawsuits and Other Proceedings, no liabilities or related receivables for insurance recoveries have been reflected in the condensed consolidated financial statements as of April 30, 2011 as these amounts are not currently estimable. The Company and its subsidiaries are subject to certain other legal actions that arise in the normal course of business. Other than those legal proceedings and claims discussed below and in the 2010 Form 10-K, the Company did not have any current other legal proceedings and claims that would individually or in the aggregate have a reasonably possible materially adverse affect on its financial condition or operating results. However, the results of legal proceedings cannot be predicted with certainty. If the Company failed to prevail in several of these legal matters in the same reporting period, the operating results of a particular reporting period could be materially adversely affected. Shareholder Derivative Lawsuits: The September Derivative (as defined in Notes 14, Contingencies and Commitments, to the Company’s consolidated financial statements included in the 2010 Form 10-K) is no longer stayed. On January 28, 2011, a third shareholder filed a derivative lawsuit in New York Supreme Court, Nassau County, against certain current directors and officers of the Company, and against the Company as nominal defendant. This action purports to bring claims on behalf of the Company similar to those alleged in the September Derivative action. The complaint seeks damages, together with various injunctive and declaratory relief. Environmental Matters: With respect to the environmental matters at the Company’s Ann Arbor, Michigan site, previously disclosed in Part I — Item 3 — Legal Proceedings in the Company’s 2010 Form 10-K, the Company and the Michigan Department of Natural Resources and Environment (the “DNRE”) reached an agreement on the principal terms to resolve all outstanding issues and presented a Joint Notice of Tentative Settlement (the “Joint Notice”) to the court on November 24, 2010. The court approved the proposed changes to the clean-up program outlined in the Joint Notice and instructed the parties to submit an amended Consent Judgment incorporating such changes. In early March 2011, the Company and the DNRE executed a Third Amendment to Consent Judgment (the “Amended Consent Judgment”) and presented the Amended Consent Judgment and a Stipulated Order Amending Previous Remediation Orders to the court, which the court approved on March 8, 2011. Based on the terms of the Amended Consent Judgment, the Company believes that its current environmental reserves are adequate. The Company’s condensed consolidated balance sheet at April 30, 2011 includes liabilities for environmental matters of approximately $10,980, which relate primarily to the previously reported environmental proceedings involving a Company subsidiary, Gelman Sciences Inc., pertaining to groundwater contamination. In the opinion of management, the Company is in substantial compliance with applicable environmental laws and its current accruals for environmental remediation are adequate. However, as regulatory standards under environmental laws are becoming increasingly stringent, there can be no assurance that future developments, additional information and experience gained will not cause the Company to incur material environmental liabilities or costs beyond those accrued in its condensed consolidated financial statements.
