PASADENA, Calif., Feb. 8 /PRNewswire/ -- Alexandria Real Estate Equities, Inc. today announced operating and financial results for the fourth quarter and year ended December 31, 2006.

For the fourth quarter of 2006, we reported total revenues of $93,440,000 and FFO available to common stockholders of $39,054,000, or $1.34 per share (diluted), compared to total revenues of $64,652,000 and FFO available to common stockholders of $27,592,000, or $1.22 per share (diluted), for the fourth quarter of 2005. Comparing the fourth quarter of 2006 to the fourth quarter of 2005, total revenues increased 45%, FFO available to common stockholders increased 42% and FFO per share (diluted) increased 10%. For the year ended December 31, 2006, we reported total revenues of $316,821,000 and FFO available to common stockholders of $131,665,000, or $5.16 per share (diluted), compared to total revenues of $238,138,000 and FFO available to common stockholders of $102,689,000, or $4.82 per share (diluted), for the year ended December 31, 2005. Comparing the year ended December 31, 2006 to the year ended December 31, 2005, total revenues increased 33%, FFO available to common stockholders increased 28% and FFO per share (diluted) increased 7%.

FFO is a non-GAAP measure widely used by publicly-traded real estate investment trusts. A reconciliation of GAAP net income available to common stockholders to FFO available to common stockholders, on both an aggregate and a per share diluted basis, is included in the financial information accompanying this press release. The primary reconciling item between GAAP net income available to common stockholders and FFO available to common stockholders is depreciation and amortization expense. Depreciation and amortization expense for the three months ended December 31, 2006 and 2005 was $22,454,000 and $15,451,000, respectively. Depreciation and amortization expense for the year ended December 31, 2006 and 2005 was $74,039,000 and $55,416,000, respectively. Net income available to common stockholders for the fourth quarter of 2006 was $16,512,000, or $0.57 per share (diluted), compared to net income available to common stockholders of $12,157,000, or $0.54 per share (diluted) for the fourth quarter of 2005. Net income available to common stockholders for the year ended December 31, 2006 was $57,326,000, or $2.25 per share (diluted), compared to net income available to common stockholders of $47,343,000, or $2.22 per share (diluted) for the year ended December 31, 2005.

For the fourth quarter of 2006, we executed a total of 34 leases for approximately 427,000 square feet of space at 23 different properties (excluding month-to-month leases). Of this total, approximately 187,000 square feet related to new or renewal leases of previously leased space and approximately 240,000 square feet related to redeveloped, developed or previously vacant space. Of the 240,000 square feet, approximately 177,000 square feet were delivered from our redevelopment or development programs, with the remaining approximately 63,000 square feet related to previously vacant space. Rental rates for these new or renewal leases were on average approximately 29% higher (on a GAAP basis) than rental rates for expiring leases. For the year ended December 31, 2006, we executed a total of 113 leases for approximately 1,588,000 square feet of space at 54 different properties (excluding month-to-month leases). Of this total, approximately 705,000 square feet related to new or renewal leases of previously leased space and approximately 883,000 square feet related to redeveloped, developed or previously vacant space. Of the 883,000 square feet, approximately 603,000 square feet were delivered from our redevelopment or development programs, with the remaining approximately 280,000 square feet related to previously vacant space. Rental rates for new or renewal leases were on average approximately 14.1% higher (on a GAAP basis) than rental rates for expiring leases.

During the fourth quarter of 2006, we acquired 8 properties aggregating approximately 573,000 square feet. The aggregate consideration was approximately $229 million. The largest property aggregating approximately 185,000 rentable square feet in the Eastern Massachusetts market is currently occupied by multiple tenants. In addition to the existing rentable square footage of approximately 185,000, this property also has an additional 240,000 developable square footage.

As of December 31, 2006, approximately 90% of our leases (on a square footage basis) were triple net leases, requiring tenants to pay substantially all real estate taxes and insurance, common area and other operating expenses, including increases thereto. In addition, as of December 31, 2006, approximately 4% of our leases (on a square footage basis) required the tenants to pay a majority of operating expenses. Additionally, as of December 31, 2006, approximately 91% of our leases (on a square footage basis) provided for the recapture of certain capital expenditures and approximately 89% of our leases (on a square footage basis) contained effective annual rent escalations that are either fixed or indexed based on the consumer price index or another index.

Based on our current view of existing market conditions and certain current assumptions, our guidance for FFO per share (diluted) and earnings per share (diluted) is as follows:

2007 ----- FFO per share (diluted) $5.71 Earnings per share (diluted) $2.35

Financial Information (Unaudited) Funds from Operations

Generally accepted accounting principles ("GAAP") basis accounting for real estate assets utilizes historical cost accounting and assumes real estate values diminish over time. In an effort to overcome the difference between real estate values and historical cost accounting for real estate assets, the Board of Governors of the National Association of Real Estate Investment Trusts ("NAREIT") established the measurement tool of Funds From Operations ("FFO"). Since its introduction, FFO has become a widely used non-GAAP financial measure by REITs. We believe that FFO is helpful to investors as an additional measure of the performance of an equity REIT. We compute FFO in accordance with standards established by the Board of Governors of NAREIT in its April 2002 White Paper (the "White Paper") and related implementation guidance, which may differ from the methodology for calculating FFO utilized by other equity REITs, and, accordingly, may not be comparable to such other REITs. The White Paper defines FFO as net income (loss) (computed in accordance with GAAP), excluding gains (or losses) from sales, plus real estate related depreciation and amortization, and after adjustments for unconsolidated partnerships and joint ventures. While FFO is a relevant and widely used measure of operating performance for REITs, it should not be considered as an alternative to net income (determined in accordance with GAAP) as an indication of financial performance, or to cash flows from operating activities (determined in accordance with GAAP) as a measure of our liquidity, nor is it indicative of funds available to fund our cash needs, including our ability to make distributions.

The following table presents a reconciliation of net income available to common stockholders, the most directly comparable GAAP financial measure to FFO, to funds from operations available to common stockholders for the three months and year ended December 31, 2006 and 2005 (in thousands, except per share data):

Same Property Occupancy for the quarters ended December 31, 2006 and 2005 was 95.5% and 95.7%, respectively. Same Property Occupancy for the year ended December 31, 2006 and 2005 was 95.8% and 95.8%, respectively. Properties undergoing redevelopment are excluded from same property results. If the portion of redevelopment properties not undergoing redevelopment were included in the Same Property results, the percentage change in GAAP Basis and Cash Basis revenue less operating expenses associated with the Fourth Quarter Same Properties, as applicable, (excluding lease termination fees, if any) less property operating expenses for the quarters ended December 31, 2006 and 2005 would have been 2.6% and 3.9%, respectively. If the portion of redevelopment properties not undergoing redevelopment were included in the Same Property results, the percentage change in GAAP Basis and Cash Basis revenue less operating expenses associated with the 2006 Same Properties, as applicable, (excluding lease termination fees, if any) less property operating expenses for the year ended December 31, 2006 and 2005 would have been 3.2% and 5.0%, respectively. (1) Revenue less operating expenses computed under GAAP is total revenue associated with the Fourth Quarter Same Properties and 2006 Same Properties, as applicable, (excluding lease termination fees, if any) less property operating expenses. Under GAAP, rental revenue is recognized on a straight-line basis over the respective lease terms. Revenue less operating expenses on a cash basis is total revenue associated with the Fourth Quarter Same Properties and 2006 Same Properties, as applicable, (excluding lease termination fees, if any) less property operating expenses, adjusted to exclude the effect of straight-line rent adjustments required by GAAP. Straight-line rent adjustments for the quarters ended December 31, 2006 and 2005 for the Fourth Quarter Same Properties were $1,764,000 and $2,433,000, respectively. Straight-line rent adjustments for the year ended December 31, 2006 and 2005 for the 2006 Same Properties were $7,032,000 and $9,436,000, respectively. We believe that revenue less operating expenses on a cash basis is helpful to investors as an additional measure of operating performance because it eliminates straight-line rent adjustments to rental revenue. (2) Fees received from tenants in connection with termination of their leases, if any, are excluded from revenue in the Same Property Comparisons. As of December 31, 2006, approximately 90% of our leases (on a square footage basis) were triple net leases, requiring tenants to pay substantially all real estate taxes and insurance, common area and other operating expenses, including increases thereto. In addition, as of December 31, 2006, approximately 4% of our leases (on a square footage basis) required the tenants to pay a majority of operating expenses. ALEXANDRIA REAL ESTATE EQUITIES, INC.

Pursuant to SFAS 34 and SFAS 67, capitalization of construction, development and redevelopment costs, including interest, is required while activities are ongoing to prepare an asset for its intended use. Pre-construction costs includes costs related to the development of plans and the process of obtaining entitlements and permits from government authorities. Costs incurred after a project is substantially complete and ready for its intended use are expensed as incurred. Should development, redevelopment or construction activity cease, construction costs, including interest, would no longer be eligible for capitalization, under SFAS 34 and SFAS 67, and would be expensed as incurred. Interest mandated to be capitalized on ground-up development, active redevelopment and other construction projects, including development/pre-construction on certain land parcels, for the three months ended December 31, 2006, was approximately $9.0 million. (1) Our aggregate construction costs to date approximate $50 per developable square foot. (2) This development project is partially leased and the balance is under negotiation. (3) Our redevelopment program involves ongoing activities necessary for the permanent change of use of applicable redevelopment space to office/laboratory space. Spaces currently built out with laboratory improvements are generally not placed into our value-add redevelopment program. As required under GAAP, interest and other costs directly related and essential to the project are capitalized on redevelopment properties on the basis allocable only to that portion of space undergoing redevelopment. In addition to properties undergoing redevelopment, as of December 31, 2006 our asset base contains imbedded opportunities for future permanent change of use to office/laboratory space through redevelopment aggregating approximately 1.2 million rentable square feet.

A significant portion of our imbedded future development square footage is in the development/pre-construction phase (entitlement, permitting, design, etc.). See discussion on SFAS 34 and SFAS 67 on page 17. The exact date of physical construction will depend on successful completion of development/pre-construction activities and management's assessment of overall market conditions. As required under GAAP, direct construction, interest, property taxes, insurance and other costs directly related and essential to the development/pre- construction, or construction of a project, is mandated to be capitalized during pre-construction when activities are ongoing to bring these assets to their intended use. (1) Approximately 2.7 million developable square feet located in the San Francisco Bay market is in development/pre-construction. (2) Approximately 427,000 developable square feet located in the San Diego market is in development/pre-construction. (3) Approximately 494,000 developable square feet located in the Suburban Washington D.C. market is in development/pre- construction.

Summary of Capital Costs For the Year Ended December 31, 2006 (In thousands) Property-related capital expenditures (1) $1,214 Leasing costs (2) $369 Property-related redevelopment costs (3) $107,979 Property-related development costs (3) $169,891 (1) Property-related capital expenditures include all major capital and recurring capital expenditures except capital expenditures that are recoverable from tenants, revenue-enhancing capital expenditures, or costs related to the redevelopment of a property. Major capital expenditures consist of roof replacements and HVAC systems which are typically identified and considered at the time the property is acquired. Capital expenditures fluctuate in any given period due to the nature, extent or timing of improvements required and the extent to which they are recoverable from tenants. Approximately 91% of our leases (based on rentable square feet) provide for the recapture of certain capital expenditures (such as HVAC systems maintenance and/or replacement, roof replacement and parking lot resurfacing). In addition, we implement an active preventative maintenance program at each of our properties to minimize capital expenditures. (2) Leasing costs consist of tenant improvements and leasing commissions related to leasing of acquired vacant space and second generation space. (3) Amount includes leasing costs related to development and redevelopment projects. ALEXANDRIA REAL ESTATE EQUITIES, INC.
