The Company’s reported FFO for the first nine months of 2012 included the $0.9 million of other income discussed above. The Company’s reported FFO for the first nine months of 2011 included costs related to the redemption of preferred stock, offset by the technology sale gain discussed above, totaling a net reduction to FFO of $1.3 million.

For the nine months ended September 30, 2012, average economic occupancy at the Company’s mature communities was 96.2%, compared to 95.5% for the nine months ended September 30, 2011.

Development Activity

The Company previously announced the development of its Post Soho Square™ apartment community located in the Hyde Park submarket of Tampa, Florida. Post Soho Square™ is planned to consist of 231 apartment units with an average unit size of approximately 880 square feet and approximately 10,556 square feet of retail space. The community is expected to have a total estimated development cost of approximately $39.8 million. The Company anticipates that first apartment unit deliveries will occur in the first quarter of 2014.

In September and October 2012, the Company began leasing units at its Post South Lamar™ apartment community located in Austin, Texas and at the third phase of its Post Midtown Square^® apartment community in Houston, Texas. As of October 26, 2012, Post South Lamar™ and Post Midtown Square^®—Phase III were 11.7% and 3.2% leased, respectively.

In the aggregate, the Company has 2,046 units in seven apartment communities, and approximately 45,085 square feet of retail space, under development or in lease-up with a total estimated cost of $340.2 million. The Company currently expects to utilize available borrowings under its unsecured bank credit facilities, or other indebtedness, as well as net proceeds from its on-going condominium sales and its at-the-market common equity sales program to fund future estimated construction expenditures.

Financing Activity

Corporate Credit Ratings

In September and October 2012, Standard and Poor’s Ratings Services and Moody’s Investors Service raised the Company’s corporate credit and senior unsecured credit ratings to BBB/Baa2, from BBB-/Baa3, respectively, and revised the Company’s outlook to stable, from positive.

As a result of these ratings actions, effective as of October 1, 2012, the interest rate on the Company’s $300 million unsecured bank term loan was reduced by 0.20%, to LIBOR plus 1.70%. After considering the interest rate swaps that hedge this debt, the unsecured term loan now bears interest at a blended fixed rate of approximately 3.24% (subject to any further adjustment based on subsequent changes in the Company’s credit ratings). The interest rates on the Company’s combined $330 million unsecured revolving lines of credit were also reduced as of that date by 0.175%, to LIBOR plus 1.225%, and the annual facility fee on the syndicated revolving line of credit was reduced as of that date by 0.075%, to 0.225% per annum.

Debt Retirement

On October 10, 2012, the Company repaid $53.0 million of secured mortgage indebtedness that became open for prepayment at par. The stated interest rate on the note was 5.50%, and it was originally scheduled to mature in January 2013.

At-the-Market Common Equity Activity

During the third quarter of 2012, the Company completed the sell-out of its initial at-the-market (ATM) common equity program that provided for the sale of up to 4 million shares of common stock. The Company also has available a second ATM common equity program that provides for the sale of up to an additional 4 million shares of common stock. As of October 26, 2012, no shares have been issued under that program. The Company expects to continue to use its ATM program as an additional source of capital and liquidity, to maintain the strength of its balance sheet and to fund its planned investment activities. Sales under these programs are dependent upon a variety of factors, including, among others, market conditions, the trading price of the Company’s common stock, the Company’s liquidity position and the potential use of proceeds.

During the third quarter of 2012, the Company sold 136,500 shares under the initial ATM program, at an average gross price of $51.24 per share, producing net proceeds of $6.8 million. Since inception of this program, the Company has sold 4,000,000 shares, at an average gross price of $41.48 per share, producing net proceeds of $162.2 million.

FUNDS FROM OPERATIONS

(In thousands)

(Unaudited)

The Company uses the National Association of Real Estate Investment Trusts (“NAREIT”) definition of funds from operations (“FFO”). FFO is defined by NAREIT as net income available to common shareholders determined in accordance with GAAP, excluding gains (or losses) from extraordinary items and sales of depreciable property, plus depreciation of real estate assets, and after adjustment for unconsolidated partnerships and joint ventures all determined on a consistent basis in accordance with GAAP. FFO is a supplemental non-GAAP financial measure. FFO presented herein is not necessarily comparable to FFO presented by other real estate companies because not all real estate companies use the same definition. The Company’s FFO is comparable to the FFO of real estate companies that use the current NAREIT definition.

The Company also uses FFO as an operating measure. Accounting for real estate assets using historical cost accounting under GAAP assumes that the value of real estate assets diminishes predictably over time. NAREIT stated in its April 2002 White Paper on Funds from Operations “since real estate asset values have historically risen or fallen with market conditions, many industry investors have considered presentations of operating results for real estate companies that use historical cost accounting to be insufficient by themselves.” As a result, the concept of FFO was created by NAREIT for the REIT industry to provide an alternate measure. Since the Company agrees with the concept of FFO and appreciates the reasons surrounding its creation, management believes that FFO is an important supplemental measure of operating performance. In addition, since most equity REITs provide FFO information to the investment community, the Company believes FFO is a useful supplemental measure for comparing the Company’s results to those of other equity REITs. The Company believes that the line on the Company’s consolidated statement of operations entitled “net income available to common shareholders” is the most directly comparable GAAP measure to FFO.

FFO should not be considered as an alternative to net income available to common shareholders (determined in accordance with GAAP) as an indicator of the Company’s financial performance. While management believes that FFO is an important supplemental non-GAAP financial measure, management believes it is also important to stress that FFO should not be considered as an alternative to cash flow from operating activities (determined in accordance with GAAP) as a measure of the Company’s liquidity. Further, FFO is not necessarily indicative of sufficient cash flow to fund all of the Company’s needs or ability to service indebtedness or make distributions.

A reconciliation of net income available to common shareholders to FFO available to common shareholders and unitholders for the three and nine months ended September 30, 2012 and 2011 was as follows.

MATURE (SAME STORE) COMMUNITY DATA

(In thousands)

(Unaudited)

The Company defines same store communities as those which have reached stabilization prior to the beginning of the previous year. For the 2012 to 2011 comparison, fully stabilized communities are defined as those communities which reached stabilization prior to January 1, 2011. This portfolio consisted of 50 communities with 18,114 units, including 13 communities with 5,407 units (29.8%) located in Atlanta, Georgia, 14 communities with 4,498 units (24.8%) located in Dallas, Texas, 6 communities with 2,301 units (12.7%) located in the greater Washington D.C. metropolitan area, 4 communities with 2,111 units (11.7%) located in Tampa, Florida, 4 communities with 1,388 units (7.7%) located in Charlotte, North Carolina and 9 communities with 2,409 units (13.3%) located in other markets. The operating performance of these communities was as follows:

The Company uses same store annually recurring and periodically recurring capital expenditures as cash flow measures. Same store annually recurring and periodically recurring capital expenditures are supplemental non-GAAP financial measures. The Company believes that same store annually recurring and periodically recurring capital expenditures are important indicators of the costs incurred by the Company in maintaining same store communities. The corresponding GAAP measures include information with respect to the Company’s other operating segments consisting of communities stabilized in the prior year, and commercial properties in addition to same store information. Therefore, the Company believes that its presentation of same store annually recurring and periodically recurring capital expenditures is necessary to demonstrate same store replacement costs over time. The Company believes that the most directly comparable GAAP measure to same store annually recurring and periodically recurring capital expenditures is the line on the Company’s consolidated statements of cash flows entitled “property capital expenditures.”
