We are one of the largest public REITs focused on medical office buildings in the United States based on gross leasable area, or GLA, and 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 and to provide an attractive risk-adjusted return for our stockholders by consistently increasing our cash flow. In pursuing this objective, we (i) target mid-sized acquisitions of high-quality medical office buildings in markets with dominant healthcare systems, attractive demographics and that complement our existing portfolio, (ii) actively manage our balance sheet to maintain flexibility with conservative leverage, and (iii) seek internal growth through proactive asset management, leasing and property management oversight. We have qualified to be taxed as a REIT for federal income tax purposes and we intend to continue to be taxed as a REIT. We conduct substantially all of our operations through Healthcare Trust of America Holdings, LP, or our operating partnership.</font></div><div style="line-height:120%;padding-top:6px;text-indent:30px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">We invest primarily in high-quality medical office buildings in our target markets, and have acquired high-quality medical office buildings and other facilities that serve the healthcare industry with an aggregate purchase price of </font><font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;">$2.6 billion</font><font style="font-family:inherit;font-size:10pt;"> through </font><font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;">December 31, 2012</font><font style="font-family:inherit;font-size:10pt;">.

Differences between rental income recognized and amount contractually due under the lease agreements will be credited or charged, as applicable, to deferred rent receivables. Tenant reimbursement revenue, which is comprised of additional amounts recoverable from tenants for common area maintenance expenses and certain other recoverable expenses, is recognized as revenue in the period in which the related expenses are incurred.

This guidance requires that these reimbursements be recorded on a gross basis, as we are generally the primary obligor with respect to purchasing goods and services from third-party suppliers, have discretion in selecting the supplier, and have credit risk. We recognize lease termination fees if there is a signed termination letter agreement, all of the conditions of the agreement have been met, and the tenant is no longer occupying the property. Rental income is reported net of amortization recorded on lease inducements.</font></div></div>
