well, State ownership is not a factor, as the EU was not allowed to decide on forms of ownership, but State-owned firms are supposed to finance themselves without a State guarantee, explicit or implicit.

That applied to EDF but also to the Landesbanken, whose business model (borrow cheap and lend cheap to local companies) was broken by the EU to comply with the "competition" demands of the London-based (and US-owned) investment banks. So they had to borrow expensive, and turned to crazy stuff like MBS to earn the equivalent revenue, while their past clients went to the investment banks for loans (and get cut off at times of crisis...)
