(the “Company”) is a fully-integrated, self-administered and self-managed real estate investment trust (“REIT”), formed as a Maryland corporation on April 30, 2004, to own, operate, manage, acquire, develop and redevelop professionally managed self-storage facilities located throughout the United States. The Company continues the business of Extra Space Storage LLC and its subsidiaries, which had engaged in the self-storage business since 1977. The Company’s interest in its properties is held through its operating partnership, Extra Space Storage LP (the “Operating Partnership”), which was formed on May 5, 2004. The Company’s primary assets are general partner and limited partner interests in the Operating Partnership. This structure is commonly referred to as an umbrella partnership REIT, or UPREIT. The Company has elected to be taxed as a REIT under the Internal Revenue Code of 1986, as amended.  To the extent the Company continues to qualify as a REIT, it will not be subject to tax, with certain limited exceptions, on the taxable income that is distributed to its stockholders.</font></p> <p style="MARGIN: 0in 0in 0pt;"> </p> <p style="MARGIN: 0in 0in 0pt;"><font style="FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt;" size="2">The Company invests in self-storage facilities by acquiring wholly-owned facilities or by acquiring an equity interest in real estate entities.  At September 30, 2013, the Company had direct and indirect equity interests in 754 operating storage facilities.  In addition, the Company managed 253 properties for third parties, bringing the total number of operating properties which it owns and/or manages to 1,007.  These properties are located in 35 states, Washington, D.C. and Puerto Rico.</font></p> <p style="MARGIN: 0in 0in 0pt;"> </p> <p style="MARGIN: 0in 0in 0pt;"><font style="FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt;" size="2">The Company operates in three distinct segments: (1) rental operations; (2) tenant reinsurance; and (3) property management, acquisition and development. The rental operations activities include rental operations of self-storage facilities in which we have an ownership interest. No single tenant accounts for more than 5% of rental income.  Tenant reinsurance activities include the reinsurance of risks relating to the loss of goods stored by tenants in the Company’s self-storage facilities. The Company’s property management, acquisition and development activities include managing, acquiring, developing and selling self-storage facilities.</font></p> <p style="MARGIN: 0in 0in 0pt;"> </p> <p style="TEXT-INDENT: -0.25in; MARGIN: 0in 0in 0pt 0.25in;"> </p> </div>
