In its 2011 report, conducted in partnership with IDC and Ipsos Public Affairs, the BSA stated: "Over half of the world's personal computer users – 57 percent – admit to pirating software." The ninth annual "BSA Global Software Piracy Study" claims that the "commercial value of this shadow market of pirated software" was worth US$63.4 billion in 2011, with the highest commercial value of pirated PC software existent in the U.S. during that time period (US$9,773,000). According to the 2011 study, Zimbabwe was the nation with the highest piracy rate, at 92%, while the lowest piracy rate was present in the U.S., at 19%.
