Theoretically a buyout could happen at anytime. Personally, I don't think a buyout will happen anytime soon.
There are several implications.
1) EuroDIsney SCA has a very complicated structure. The Phase 1 and 2 construction companies are essentially worthless paper entities that hold the debt. This debt is owned by assorted Hedge Funds. They will be after more than their pound of flesh for the debt if a rich suitor such as TWDC comes a knockin'
2) Prince Alwaleed will also be after substantial recompense for having rescued the venue. However, he may stay on a minority stakeholder
3) The small shareholders (like me!) are the losers. We would receive a fraction or even nothing if a surreptitious takeover happens. TWDC would not like the bad publicity.
4) TWDC cannot afford to pay the commercial rate for the shares AND shoulder the debt burden. They would wait until EuroDisney SCA fails naturally.
The more I think about this, the more I am seeing this as a money saving exercise only. EDSCA saves millions. TWDC looks great as a knight in shining armour and saves money if it has to buy out the resort AND starts to earn money from the character licenses. The interest rate is better as TWDC can use their borrowing power to refinance up against a failing currency. For if (when) the Euro fails the debt will be significantly less.
A good move by TWDC, but one which will be a 5 year plus plan before the real reasons are known!
