15. Commitments and Contingencies The Company has obligations related to commitments to purchase certain goods and services. As of March 30, 2012, such obligations were $182 million for fiscal 2012, $3 million for fiscal 2013, $2 million for fiscal 2014, and $0 thereafter. Legal Contingencies  The Company is a defendant in a number of pending legal proceedings incidental to present and former operations, including several lawsuits alleging that the anti-microbial coated sprinkler pipe causes stress cracking in polyvinyl chloride pipe when installed with certain kinds of such pipe manufactured by unrelated parties. After consultation with internal counsel and external counsel representing the Company in these matters, the Company has reserved its best estimate of the probable loss related to the matter. The Company had an accrual of $6 million and $8 million as of March 30, 2012, and September 30, 2011, respectively. The accrual liability was included in other liabilities in the consolidated balance sheet for this matter. The Company does not expect the outcome of these proceedings, either individually or in the aggregate, to have a material effect on its financial statements. The range of reasonably possible losses related to these matters is from $3 million to $12 million. In October 2010, the Company was notified of an assessment by the Rio Grande do Sul State Treasury Secretariat related to the appropriateness of certain value-added tax credits taken in Brazil during the periods 2005 to 2007. The Brazilian government alleges that the Company owes approximately $10 million in taxes, penalties and interest. The Company has been vigorously defending the matter based on its belief that its position was in accordance with the applicable law based in part upon the findings of the third party that assisted us in documenting and responding to the notice. On April 11, 2012, the administrative court of Rio Grande do Sul State issued two unfavorable rulings against the Company. The Company has no further appeal options o
