S&P downgrades Europe oil outlook on lower prices

Standard & Poor's has downgraded its outlook for some European oil companies as prices continue their slide.

"The updated assumptions reflect the precipitous declines in futures prices for Brent, the result of a combination of relatively unconstrained supply — notably on the back of sustained oil growth in North America — and weaker demand," according to an S&P press release.

S&P also updated its price assumptions for Brent to $70 billion-$75 billion for 2015-'16, according to the release.
