Outlook

For the third quarter of 2013, the Company has established the following guidance ranges.

Previously on June 26, 2013, the Company had raised its FFO, FFO as Adjusted, and AFFO per share guidance at the mid-point by $0.02 each, primarily due to better-than-expected same-store and non-same-store operating trends. Below are the full-year guidance ranges.

Below are the full-year same-store growth assumptions, which were previously increased on June 26, 2013.
