Due to circumstances at the gymnastics venue at the 2013 World Games in Cali, Colombia, the International Gymnastics Federation informed its member federations that it found the conditions violate its rules and regulations. As a result, the FIG asked its member federations to sign a waiver (excerpts are included below) requesting a waiver of responsibility for providing a safe environment for the athletes. USA Gymnastics has declined to sign the waiver because its content is unacceptable and places an unusual burden on the athletes and member federations.
"Our athletes traveled to Colombia with the hope that the problems might be adequately resolved," said Steve Penny, president of USA Gymnastics.
