I'm getting the story now.
In 2011, DuPont realized that KBLB would, a decade or more down the road, be successful. So they sent a 70-year-old Joe Cunning to lay the groundwork.
Over the next 10+ years, DuPont could have stepped in at any time, announced a joint ventureship with KBLB, helped them along, and then been able to propose a merger on friendly terms. Instead they kept their interest quiet to prevent a stampede so they could purchase KBLB for the bargain price of $20 billion, a mere 224 times more than the current market cap. Imagine the stampede that might have happened if everyone knew DuPont was interested!
Fortunately, Cunning lived another 10 years, even though he didn't last that long on the advisory board of KBLB. But when KBLB wanted an infusion of cash, DuPont once again kept things on the down low. If their interest had ever been detected, they might have been forced to pay an extra billion dollars for KBLB?
Seriously, a great and foolproof plan.
