Bad news for BP

• The ruling: BP bears 67 percent of the responsibility for the 2010 Gulf of Mexico oil spill, Swiss-based drilling rig owner Transocean Ltd. 30 percent, and Houston-based cement contractor Halliburton Energy Services 3 percent.

• What’s next: In the next stage of the case, the judge will decide how much BP must pay.

• Looking back: Eleven rig workers were killed in the nation’s worst offshore oil disaster. Government experts estimated nearly 5 million barrels spilled into the Gulf.
