AUSTIN, Texas--(BUSINESS WIRE)--American Campus Communities, Inc. (NYSE:ACC) today announced the following financial results for the quarter ended March 31, 2008.

Highlights

Quarterly FFOM of $0.38 per fully diluted share, compared to zero FFOM for the same period prior year, which included a compensation charge of $0.38 per fully diluted share recorded in the first quarter 2007 related to the company’s 2004 Outperformance Bonus Plan.

First Quarter 2008 Operating Results

Revenue for the 2008 first quarter totaled $41.4 million, up 18.6 percent from $35.0 million in the 2007 first quarter. Net income for the 2008 first quarter totaled $4.9 million, or $0.18 per fully diluted share, and includes $153,000 of GMH merger expenses, or $0.01 per fully diluted share. This compares to a net loss of $4.7 million, or $0.20 per fully diluted share, for the same quarter in 2007. The company’s net loss for the 2007 first quarter was due to a compensation charge of $9.6 million, or $0.38 per fully diluted share, related to the company’s 2004 Outperformance Bonus Plan. FFO for the 2008 first quarter totaled $13.2 million, or $0.45 per fully diluted share, and FFOM for the 2008 first quarter was $11.2 million or $0.38 per fully diluted share. A reconciliation of FFO and FFOM to net income is shown on Table 3.

NOI for same store wholly-owned properties was $15.4 million in the quarter, up 6.3 percent from $14.5 million in the 2007 first quarter. NOI for the total wholly-owned property portfolio increased 16.7 percent to $18.2 million for the quarter from $15.6 million in the comparable period of 2007, primarily due to the impact of acquisitions completed during both periods and a development property placed into service during 2007.

Subsequent to Quarter End

Leasing status for the same store wholly-owned portfolio was 87 percent applied for and 82 percent leased for the 2008-2009 academic year as of April 25, 2008. This compares to 89 percent applied for and 84 percent leased for the same period prior year. The company’s total owned portfolio is 87 percent applied for and 81 percent leased.

The company was recently selected by Boise State University to begin the planning process for the development of an ACE™ (American Campus Equity) project. This potential multi-phased project could ultimately result in a housing development containing approximately 2,000 beds.

On April 23, 2008, the company completed a public offering of 9,200,000 shares of its common stock at a price of $28.75 per share, which includes 1,200,000 shares issued as a result of the underwriters' exercise of their over-allotment option in full at the closing. The company received approximately $252.4 million in net proceeds from the offering.

“Q1 2008 was a monumental quarter for American Campus with the announcement of our acquisition of the GMH student housing platform,” said Bill Bayless, ACC CEO. “We believe we can unlock the value of these assets by applying our proven operating platform, which this quarter generated a 6.3 percent increase in same store NOI compared to Q1 2007. In addition, being selected by Boise State to develop multiple projects under our ACE program is an important step in establishing ACE as the optimal choice for universities looking to improve on-campus housing while preserving their credit capacity.”

Non-GAAP Financial Measures

As defined by NAREIT, FFO represents income (loss) before allocation to minority interests (computed in accordance with GAAP), excluding gains (or losses) from sales of property, plus real estate related depreciation and amortization (excluding amortization of loan origination costs) and after adjustments for unconsolidated partnerships and joint ventures. We present FFO because we consider it an important supplemental measure of our operating performance and believe it is frequently used by securities analysts, investors and other interested parties in the evaluation of REITs, many of which present FFO when reporting their results. FFO is intended to exclude GAAP historical cost depreciation and amortization of real estate and related assets, which assumes that the value of real estate diminishes ratably over time. Historically, however, real estate values have risen or fallen with market conditions. Because FFO excludes depreciation and amortization unique to real estate, gains and losses from property dispositions and extraordinary items, it provides a performance measure that, when compared year over year, reflects the impact to operations from trends in occupancy rates, rental rates, operating costs, development activities and interest costs, providing perspective not immediately apparent from net income. We compute FFO in accordance with standards established by the Board of Governors of NAREIT in its March 1995 White Paper (as amended in November 1999 and April 2002), which may differ from the methodology for calculating FFO utilized by other equity REITs and, accordingly, may not be comparable to such other REITs. Further, FFO does not represent amounts available for management's discretionary use because of needed capital replacement or expansion, debt service obligations or other commitments and uncertainties. FFO should not be considered as an alternative to net income (loss) (computed in accordance with GAAP) as an indicator of our financial performance or to cash flow from operating activities (computed in accordance with GAAP) as an indicator of our liquidity, nor is it indicative of funds available to fund our cash needs, including our ability to pay dividends or make distributions.

As noted above, FFO excludes GAAP historical cost depreciation and amortization of real estate and related assets because these GAAP items assume that the value of real estate diminishes over time. However, unlike the ownership of our owned off-campus properties, the unique features of our ownership interest in our on-campus participating properties cause the value of these properties to diminish over time. For example, since the ground leases under which we operate the participating properties require the reinvestment from operations of specified amounts for capital expenditures and for the repayment of debt while our interest in these properties terminates upon the repayment of the debt, such capital expenditures do not increase the value of the property to us and mortgage debt amortization only increases the equity of the ground lessor. Accordingly, when considering our FFO, we believe it is also a meaningful measure of our performance to modify FFO to exclude the operations of our on-campus participating properties and to consider their impact on performance by including only that portion of our revenues from those properties that are reflective of our share of net cash flow and the management fees that we receive, both of which increase and decrease with the operating measure of the properties, a measure we refer to as FFOM.

The company defines property NOI as property revenues less direct property operating expenses, excluding depreciation, but including allocated corporate general and administrative expenses.

Our share of the FFO from this unconsolidated joint venture is included for purposes of calculating the company’s FFO but is excluded for purposes of calculating FFOM, as management believes this amount does not accurately reflect the company’s participation in the economics of the transaction. For the three months ended March 31, 2008, our share of the venture’s FFO equals our share of net loss, as there was no depreciation expense incurred for the period.

⁽²⁾ 50 percent of the properties’ net cash available for distribution after payment of operating expenses, debt service (including repayment of principal) and capital expenditures. Represents amounts accrued for the interim periods.
