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. 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 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 $2.8 billion through September 30, 2013.

On June 6, 2012, HTA listed its Class A common stock on the New York Stock Exchange, or the NYSE, or the Listing. In accordance with an amendment to HTA’s charter approved by stockholders on December 20, 2010, all of the common stock was converted into Class A, Class B-1, Class B-2 and Class B-3 common stock. The Class B common stock is identical to the Class A common stock except that the Class B common stock is not currently listed on a national securities exchange. The shares of the Class B-1 and Class B-2 common stock converted into shares of our Class A common stock on December 6, 2012 and June 6, 2013, respectively, and are now listed on the NYSE. On November 4, 2013, HTA’s Board of Directors announced that the Class B-3 common stock will convert to Class A common stock after the market closes on November 7, 2013 and be eligible for trading on the NYSE.
