Certain excerpts from Kinder Morgan Quarterly Earnings Conference Call held on April 17, 2013:

Rich Kinder: If you look at the performance of each segment at KMP starting with natural gas and let me just relate to our overall feelings of natural gas across all of the Kinder Morgan companies, we believe natural gas is clearly the fossil fuel of the future. It’s domestic, clean, abundant and reasonably priced. And that makes it a clear winner for this country for decades to come.

One of the biggest challenges to this rosy scenario is to overcome the obstacles in midstream infrastructure to ensure that there’s adequate capacity to connect the new sources of supply to the markets where the demand is. Now if you look at Kinder Morgan specifically we have 62,000 miles of gas pipeline. We’ll have about 70,000 post the Copano merger so I think our companies are ideally situated to help meet this challenge of providing the needed infrastructure in North America.

…

We expect to close on the Copano acquisition in early May. As we’ve told you previously we expect that to be modestly accretive to KMP in 2013 and that’s not in our present forecast numbers. And we expect it to be about 10 cents accretive in 2014 and beyond.
