USA Gymnastics proposed a plan Thursday in federal bankruptcy court that would settle all civil claims made against the organization in the wake of the Larry Nassar sexual assault scandal for $215 million.

That $215 million total, according to documents filed in the Southern District of Indiana, is the amount USA Gymnastics' insurance carriers are willing to provide the sport's national governing body to end years of legal battles with athletes who were abused by the former national team doctor.

An attorney representing more than 180 Nassar survivors called Thursday's proposal "dead on arrival."

Hundreds of athletes and former patients have come forward over the past three years saying Nassar abused them under the guise of treatment, including reigning Olympic champion Simone Biles. More than 500 women have active civil claims against USA Gymnastics.

USA Gymnastics president Li Li Leung told The Associated Press on Thursday that the organization wants to "work toward a true consensual settlement" with survivors.

Leung described the $215 million as the amount the insurance carriers have agreed to provide at this point.

"Our hope is that discussions will continue and more money will be [available]," said Leung, who took over in March 2019, several months after Indianapolis-based USA Gymnastics filed for bankruptcy protection. "It's not capped at $215 [million]."

But Irvine, California, attorney John Manly, who represents more than 180 clients with active claims against USAG, said the proposal doesn't go far enough.

The proposed settlement does not include any money, for example, from the U.S. Olympic and Paralympic Committee, which has been named as a co-defendant in more than half of the 511 lawsuits.

Under the terms of the proposal, Manly said, the USOPC would be discharged, so some of his clients, such as 2012 Olympic gold medalist McKayla Maroney, who is suing the USOPC but not USAG, would receive nothing from the settlement.

"At the end of the day, the USOPC pays nothing and gets a discharge. To me, it's just glaring that the USOPC is completely controlling this process," Manly told ESPN on Thursday.

There is a two-step voting process for claimants to determine whether to accept the offer. At least half the claimants who vote have to approve the proposal. The claimants also could vote down the measure and continue to pursue their lawsuits to collect any judgments from insurance policies available to USA Gymnastics, or they could not vote on it at all and discuss how to go forward.

"No one is going to vote for this," Manly told ESPN on Thursday. "This is a cynical attempt [by USAG] to gain favor with the media and the public. This is never going to be accepted, and they know it."

Michigan State University, where Nassar worked for decades, agreed in May 2018 to pay $500 million to more than 300 women and girls who said they were assaulted by Nassar.

If claimants agree to accept Thursday's proposal, the $215 million will be placed into a trust, with the money then distributed by a trustee. A judge would decide how the $215 million is allocated.

If the survivors vote to accept the settlement, insurers for Twistars USA Gymnastics, the gym near Lansing, Michigan, once owned by 2012 Olympic head coach John Geddert, would agree to contribute an additional $2.125 million to the $215 million offer, USAG said in a statement Thursday. Dozens of girls and young women say Nassar sexually assaulted them during purported treatment sessions while he worked as a volunteer at Twistars. The gym is now owned by Geddert's family members.

The plan put forth by the organization also requires it to continue to strengthen its athlete safety policies. USA Gymnastics revamped its Safe Sport policy last summer and hired its first vice president of athlete health and wellness last December.

"The most important part to the victims is not the money," Manly said, adding, "The most important thing to them is the disclosure of documents. It's important we know how this happened and who is responsible. It's the documents and disclosure that our clients believe will change the culture."

He cautioned that Thursday's court filings provide no requirement for USAG or the USOPC to provide evidence relating to the case, evidence that might shed more light on how Nassar was able to sexually assault gymnasts for decades.

USA Gymnastics hopes to have a bankruptcy exit plan of some kind approved ahead of the Tokyo Olympics, which begin in July.
