New York (CNN Business) MGM Resorts thinks it could pay as much as $800 million for lawsuits related to the 2017 massacre in Las Vegas, though it's not clear when or if settlements will be reached.

Deals have not yet been reached between MGM and thousands of people who sued the company for a variety of reasons after a man killed 58 people and wounded more than 500 others by shooting from the window of MGM's Mandalay Bay hotel. The attack on attendees of a music festival was the deadliest mass shooting in modern US history.

"MGM's stated goal regarding mediation is, as it always has been, to resolve these matters so that all impacted can move forward in their healing process," the company said in an emailed statement Friday. "After multiple mediation sessions over several months, progress has been made, and while mediation is ongoing, the Company believes it is reasonably possible that a settlement will be reached.

But Robert Eglet, an attorney who says he represents more than half of the estimated 4,200 claimants, told CNN Business that they are still "a long way from a settlement, if it does settle."

"It's just as possible at this point that it doesn't," Eglet said. He added that if a settlement is not reached, attorneys involved in the case will once again pursue litigation.
