PARIS, Sept 9 (Reuters) - Credit ratings agency Standard & Poor's has put French nuclear power engineering group Areva on "credit-watch negative" and will decide within 30 days whether to downgrade its credit ratings by one notch into non-investment grade territory.
A downgrade into the junk category would make its shares and bonds unattractive for investment funds who only seek investment-grade securities, but Areva's finance chief said the firm was not worried about its liquidity or borrowing costs.
