Pro Forma Results of Operations

The unaudited pro forma information has been prepared as if the 2014 acquisitions had taken place on January 1, 2013, and the 2013 acquisitions had taken place on January 1, 2012. The unaudited pro forma information is not necessarily indicative of the results that we would have achieved had the transactions actually taken place on January 1, 2013 and 2012, and the unaudited pro forma information does not purport to be indicative of future financial operating results.
