Senior executives at Wynn Resorts were aware of sexual misconduct allegations against founder Steve Wynn but did nothing about it.
A report by the state Gaming Commission of Massachusetts outlined years of ‘inaction and failures’ on the part of the company.
The report was released as the commission reviews whether Wynn Resorts should keep its state gaming license.
It focused in part on secret settlement payments made to some of the accusers which were not disclosed during the application for a gaming license.
"Their efforts at secrecy made it exceedingly difficult, if not impossible, for gaming regulators to detect potentially derogatory information through typical regulatory means," the report said.
The company has not denied any of the allegations made in the report and is looking to move on from a year of highly damaging headlines.
Steve Wynn was ousted last year after numerous sexual misconduct allegations were made public.
New CEO Matthew Maddox said: "I am sorry that our company did not live up to its values."
A similar investigation in Nevada saw it keep its license but was hit with a record $20 million fine.
Since the allegations were made public, Wynn Resorts says it has undertaken wide ranging reforms including dismissing every executive who knew about the allegations and took no action.
