BNSF Railroad Upgraded by S&P on Likelihood of Buffett Support

Burlington Northern Santa Fe LLC, the railroad subsidiary at Warren Buffett’s Berkshire Hathaway Inc., was upgraded to A from BBB+ by Standard & Poor’s because of the unit’s importance to the parent company.

“Given its significant size and earnings contributions relative to the consolidated group, we see a greater likelihood of support from Berkshire Hathaway in the event of unexpected financial difficulties at BNSF than previously factored into our ratings,” S&P said in a statement Friday.
