I always struggled to reconcile the 60/40 split in favour of ewc that Allen claimed.  The numbers worked closer the other way around. Nonetheless, the key advantage of the psc extension is the downstream profits at the power station and lng terminal, and having some leverage over pricing and off take.  

With respect  to your concerns  about a default to slipform - it would be super messy due to related party nature of loans. It would be more likely that there will be a workout controlled by an independent party. They would be remiss to ignore a refinancing of the slipform receivables without considering the future cash flow of the projects. SE would look super silly to claim there is no solution other than to take over the shares or to dilute shareholders given the statements he made to entity holders.  So I do think slipform/ewi/se will do the right thing.
