Pinnacle Entertainment and Ameristar Casinos say they are complying with the Federal Trade Commission on a second request of information regarding Pinnacle's proposed acquisition of Ameristar.
Officials with both companies say this is not an unusual request in a merger.
Even as construction continues on the new casino site in Lake Charles, the FTC issued the request last month to ensure the companies were meeting anti-trust regulations.
The request imposed a 30-day waiting period which should be completed by next week.
The transaction is expected to close during the second or third quarter of this year.
