OREANDA-NEWS. Marathon Petroleum Corporation (NYSE: MPC) today announced that the company expects to report earnings in the range of USD 570 million to USD 600 million, or USD 1.75 to USD 1.85 per diluted share, for the second quarter of 2013, compared with earnings of USD 814 million, or USD 2.38 per diluted share, for the second quarter of 2012. Included in the second-quarter 2013 estimate are after-tax charges of approximately USD 39 million, or USD 0.12 per share, related to pension settlement expenses compared with approximately USD 53 million, or USD 0.15 per share, in the second quarter of 2012.

Second-quarter 2013 Refining and Marketing segment results are expected to be negatively impacted in comparison to second quarter of 2012 by a number of factors, such as lower crude oil price differentials and product realizations compared to spot market values, which MPC believes were impacted by the Renewable Fuels Standard.

The company will host a conference call on Aug. 1 at 10 a.m. EDT to provide an update on company operations and to discuss 2013 second-quarter financial results, which will be released earlier that day.
