The shares were issued directly by MGM Mirage to Infinity World Investments came from the company's treasury shares. They were sold at $84 per share, more than $7 per share less than the company's current share price. Add in the 348,838 shares it acquired on Oct. 5 through its tender offer at the same price, and the discount price is worth about $100 million. The deal was inked in August , when MGM's share price was in the mid $70s per share. The share price was in the $90s when Infinity World had to go out with the tender offer in late August, which is why so few shares were tendered.
