(Reuters) - Credit rating agency Standard & Poor's on Thursday cut its rating on Berkshire Hathaway Inc
S&P cut the counterparty rating on Berkshire to "AA" from "AA+," but the agency left Berkshire's insurance units' financial strength ratings intact at "AA+."
The outlook on all ratings is negative, S&P said in a statement.
"The lower credit rating on BRK better reflects our view of BRK's dependence on its core insurance operations for most of its dividend income," said Standard & Poor's credit analyst John Iten.
