Organization and Description of Business	Organization and Description of Business HTA, a Maryland corporation, and HTALP, a Delaware limited partnership, were incorporated or formed, as applicable, on April 20, 2006. HTA operates as a REIT and is the general partner of HTALP, which is the operating partnership. As of March 31, 2016, HTA owned a 98.6% partnership interest and other limited partners, including some of HTA’s directors, executive officers and their affiliates, owned the remaining partnership interest (including the LTIP units) in HTALP. As the sole general partner of HTALP, HTA has the full, exclusive and complete responsibility for HTALP’s day-to-day management and control. HTA operates in an umbrella partnership REIT structure in which HTALP and its subsidiaries hold substantially all of the assets. HTA’s only material asset is its ownership of partnership interests of HTALP. As a result, HTA does not conduct business itself, other than acting as the sole general partner of HTALP, issuing public equity from time to time and guaranteeing certain debts of HTALP. HTALP conducts the operations of the business and issues publicly-traded debt, but has no publicly-traded equity. HTA is one of the largest publicly-traded REITs focused on medical office buildings (“MOBs”) in the United States (“U.S.”) based on gross leasable area (“GLA”). We are primarily focused on acquiring, owning and operating high quality MOBs that are predominantly located on the campuses of, or aligned with, nationally or regionally recognized healthcare systems. In addition, we have strong industry relationships, a stable and diversified tenant mix, and an extensive and active acquisition network. Our primary objective is to maximize stockholder value with disciplined growth through strategic investments that provide an attractive risk-adjusted return for our stockholders by consistently increasing our cash flow. In pursuing this objective, we: (i) seek internal growth through proactive asset management, leasing and property management oversight; (ii) target mid-sized acquisitions of MOBs in markets with dominant healthcare systems, and with attractive demographics that complement our existing portfolio; and (iii) actively manage our balance sheet to maintain flexibility with conservative leverage. HTA has qualified to be taxed as a REIT for federal income tax purposes and intends to continue to be taxed as a REIT. We primarily invest in MOBs that are located on health system campuses, in community-core locations, or around university medical centers which we believe are core, critical real estate. We also focus on our key markets that have certain demographic and macro-economic trends and where we can utilize our institutional property management and leasing platform to generate strong tenant relationships and operating cost efficiencies. Our portfolio consists of MOBs and other facilities that serve the healthcare industry with an aggregate purchase price of $3.7 billion through March 31, 2016. Our principal executive office is located at 16435 North Scottsdale Road, Suite 320, Scottsdale, Arizona, 85254.
