MGM is putting in 100 million more than her, but seems its part of the price to pay to get gaming rights in Macau. Both partys are providing the same amount of interest free loan, future cashflow should be split even 50/50.
Depends on the interest rate of the 100 million from MGM, looks like she has the local connection, MGM is providing the major financial backing, deal seems fair.
Casinos are such cash cows, imagine the money it would bring in if they opened one up in Shanghai. (not happening of course)
