Background

As used in this quarterly report on Form 10-Q, references to the “Company,” “Alexandria,” “ARE,” “we,” “us” and “our” refer to Alexandria Real Estate Equities, Inc. and its consolidated subsidiaries.

Alexandria Real Estate Equities, Inc. (NYSE:ARE), is a self-administered and self-managed investment-grade REIT, and is the largest and leading REIT focused on unique collaborative campuses in urban innovation clusters located in key coastal science and technology gateway cities, with a total market capitalization of $11.3 billion as of March 31, 2015, and an asset base of 30.7 million square feet, including 18.5 million RSF of operating and current value-creation projects, as well as an additional 2.2 million square feet of near-term value-creation development projects and 10.0 million square feet of future ground-up development projects. Alexandria pioneered this niche in 1994 and has since established a dominant market presence in AAA locations, including Greater Boston, the San Francisco Bay Area, New York City, San Diego, Seattle, Maryland, and Research Triangle Park. Alexandria is known for its high-quality and diverse client tenant base, with approximately 52% of its total annualized base rent (“ABR”) (as of March 31, 2015) generated from investment-grade client tenants. Alexandria has a longstanding and proven track record of developing Class A assets clustered in urban science and technology campuses that provide its innovative client tenants with highly dynamic and collaborative environments that enhance their ability to successfully recruit and retain world-class talent and inspire productivity, efficiency, creativity, and success. We believe these advantages result in higher occupancy levels, longer lease terms, higher rental income, higher returns, and greater long-term asset value.

•	Investment-grade client tenants represented approximately 52% of our total annualized base rent;


•	Approximately 94% of our leases (on an RSF basis) contained effective annual rent escalations that were either fixed (generally ranging from 3% to 3.5%) or indexed based on a consumer price index or other indexes;


•	Approximately 95% of our leases (on an RSF basis) were triple net leases, requiring client tenants to pay substantially all real estate taxes, insurance, utilities, common area, and other operating expenses (including increases thereto) in addition to base rent; and


•	Approximately 93% of our leases (on an RSF basis) provided for the recapture of certain capital expenditures (such as HVAC systems maintenance and/or replacement, roof replacement, and parking lot resurfacing) that we believe would typically be borne by the landlord in traditional office leases.
