We are affirming all of our ratings on CSX Corp., including our 'BBB+' corporate credit rating on the company. We are also revising our assessment of the company's liquidity to "strong" from "adequate" because we believe that CSX's sources of liquidity will be at least 1.5x its uses over the next 12-18 months. The stable outlook reflects our belief that the company will maintain credit measures that are consistent with an "intermediate" financial risk profile, given its focus on operating efficiency, despite our expectation for continued weakness in its energy-related businesses over the next year.
