Through several recent transformative transactions, we have expanded our scope of services and increased our focus on the transportation of heavier hydrocarbons. While we remain committed to the prolific natural gas industry, we enhanced our diversified portfolio of assets by making a strategic entrance into the NGL business through the acquisition of Louis Dreyfus’ NGL storage, fractionation and transportation operations in 2011. In 2012, we acquired Southern Union Company, a leading diversified natural gas company, which expanded our national footprint and added more than 20,000 miles of gathering and transportation pipelines to our portfolio. More recently, we made a strong entrance into the crude oil and refined products business by acquiring Sunoco, Inc., including its interest in Sunoco Logistics Partners L.P. (SXL).
