As a result, at any given time, Ferrellgas is threatened with or named as a defendant in various lawsuits arising in the ordinary course of business. Other than as discussed below,  Ferrellgas is not a party to any legal proceedings other than various claims and lawsuits arising in the ordinary course of business. It is not possible to determine the ultimate disposition of these matters; however, management is of the opinion that there are no known claims or contingent claims that are reasonably expected to have a material adverse effect on the financial condition, results of operations and cash flows of Ferrellgas.   Ferrellgas has been named as a defendant in lawsuits filed in multiple federal and state courts that seek to certify nationwide or statewide classes related to its Blue Rhino branded propane tank exchange activities. The plaintiffs in each case generally allege that Ferrellgas failed to inform consumers of the amount of propane contained in propane tanks they purchased and that Ferrellgas violated anti-trust laws by allegedly conspiring with a competitor. The federal cases have been coordinated for multidistrict treatment in the United States District Court for the Western District of Missouri. Based on Ferrellgas' business and consumer notification practices in its Blue Rhino tank exchange operations, Ferrellgas believes that all of these claims are without merit and intends to defend the claims vigorously.   Ferrellgas has also been named as a defendant in a class action lawsuit filed in the United States District Court in Kansas. The complaint alleges that Ferrellgas violates consumer protection laws in the manner Ferrellgas sets prices and fees for its customers.
