Nine Week Divorce Trial

I was reading an article about a recent nine week divorce trial recently where the husband was ordered to pay close to one (1) billion dollars as part of a property division.  A link tot he story is here.  It is hard for me to imagine nine weeks on a divorce trial.  This was obviously a high asset divorce where there was apparently a ton of testimony regarding whether the company the husband had increased in value due to his efforts or market forces.
