Business Combinations [Abstract]

Unaudited Pro Forma Information Based on MAA's Historical Consolidated Statement of Operations

The unaudited pro forma information set forth below is based on MAA’s historical Consolidated Statements of Operations for the years ended December 31, 2013 and 2012, adjusted to give effect to the Merger with Colonial and the acquisition of other properties in 2013 as though they occurred on January 1, 2012, the beginning of the comparable prior annual period. The pro forma adjustments primarily relate to the depreciation expense on stepped up fixed assets, amortization of acquired intangibles, and estimated interest expense related to new financings. The pro forma information is provided for illustrative purposes only and does not necessarily reflect the actual results of operations had the transactions been consummated at the beginning of the earliest year presented nor is it necessarily indicative of future operating results. The pro forma information does not give effect to any cost synergies or other operating efficiencies that could result from the Merger with Colonial.

	Pro forma (Unaudited) Period Ended December 31, (in thousands, except per share data)
	2013		2012
Total Revenue (1)	$	941,662	$	844,002
Net Income available to common shareholders (1)	$	142,593	$	100,752
Earnings per share, diluted (1)	$	1.78	$	1.45

(1) Pro forma adjustments for certain acquisitions are excluded as they had no pre-acquisition operating activity in 2012 or 2013.

The pro forma results are based on estimates and assumptions, which we believe are reasonable.
