Let's say the lawsuit is for $500M as speculated.
Now let's say that GWI has $4M in assets, and maybe $25M of D&O.
That other $470M is the responsibility of any of the directors personally named.
It's also likely joint & several responsibility, so if one of the directors is much wealthier than the other, than they will take the brunt of it.
So, what it might come down to is: Is GWI confident enough that the director is willing to put the Diamondbacks at risk if the court rules against them. Are they willing to do that even if there is only a 25% chance of losing? 10%? 5%?
Like I said, this could even be separate from the issue if this is an illegal lease. The court could easily say, 'The lease was illegal, but the letters were tortious interference anyway, because the method was improper.'
That's the only leverage the COG gets out of this, IMO. It will force the directors to decide if it's worth it to risk everything to keep up this fight.
