The scope and boundaries of the 2014 Walmart Global Responsibility Report encompass our corporate efforts related to workplace, compliance and sourcing, social and environmental responsibility, while also providing snapshots into each of our individual markets around the globe. The report reviews our progress and performance during FY2014, reflects areas where we've achieved tremendous positive results and specifies areas of opportunity we continue to focus on. The social and environmental indicators were obtained by internal survey and checks without the participation of external auditing. The reporting timeline covers the period of Feb. 1, 2013 -- Jan. 31, 2014, and builds on our last report, issued April 2013. Unless otherwise noted, all currency is in U.S. dollars.
