The following excerpts are from the footnotes that accompany Walmart's financial statements of January 31, 2015. Wage-and-Hour Class Action: The Company is a defendant in Braun/Hummel v. Wal-Mart Stores, Inc., a class-action lawsuit commenced in March 2002 in the Court of Common Pleas in Philadelphia, Pennsylvania. The plaintiffs allege that the Company failed to pay class members for all hours worked and prevented class members from taking their full meal and rest breaks.

On October 13, 2006, a jury awarded back-pay damages to the plaintiffs of approximately $78 million on their claims for off-the-clock work and missed rest breaks. The jury found in favor of the Company on the plaintiffs' meal-period claims. On November 14, 2007, the trial judge entered a final judgment in the approximate amount of $188 million, which included the jury's back-pay award plus statutory penalties, prejudgment interest and attorneys' fees. By operation of law, post-judgment interest accrues on the judgment amount at the rate of six percent per annum from the date of entry of the judgment, which was November 14, 2007, until the judgment is paid, unless the judgment is set aside on appeal. On December 7, 2007, the Company filed its Notice of Appeal. On June 10, 2011, the Pennsylvania Superior Court of Appeals issued an opinion upholding the trial court's certification of the class, the jury's back pay award, and the awards of statutory penalties and prejudgment interest, but reversing the award of attorneys' fees. On September 9, 2011, the Company filed a Petition for Allowance of Appeal with the Pennsylvania Supreme Court. On July 2, 2012, the Pennsylvania Supreme Court granted the Company's Petition.

On December 15, 2014, the Pennsylvania Supreme Court issued its opinion affirming the Superior Court of Appeals' decision. At that time, the Company recorded expenses of $249 million for the judgment amount and post-judgment interest incurred to date. The Company will continue to accrue for the post-judgment interest until final resolution. However, the Company continues to believe it has substantial factual and legal defenses to the claims at issue and, on March 13, 2015, the Company filed a petition for writ of certiorari with the U.S. Supreme Court.
