His counsel, Brian Greenspan, however, stated that Stronach denied all the accusations in at least 18 pending sexual assault complaints.

As part of the settlement, Frank and Elfriede will assume full control and ownership of a stallion and breeding business, all farm operations in North America, and all European assets.

[15] Other ventures by Stronach over the years include the "As Prime Minister, I Would…" symposium, the Fair Enterprise Institute think tank, the business magazine Vista, Frank's Energy Drink, and the beef ranch operations of Adena Farms.

Auto-parts giant Magna International Inc. and MEC are scouting for about 500 to 1,000 acres (2 to 4 km2) in an area of Baton Rouge in Louisiana to set up trailers and infrastructure.
