General Electric’s financial health came under renewed focus on Monday as Moody’s stripped the group of its long-held triple-A rating and questioned GE’s pledge that its finance arm would be profitable this year. The move was expected after rival S&P recently lowered GE’s rating by one notch to AA-plus. But Moody’s went a step further, cutting GE’s rating by two notches from triple A to Aa2, saying the financial crisis had increased the risks associated with GE Capital.
