ORGANIZATION AND NATURE OF OPERATIONS
National Storage Affiliates Trust was organized in the state of Maryland on May 16, 2013 and is a fully integrated, self-administered and self-managed real estate investment trust focused on the self storage sector. As used herein, "NSA," the "Company," "we," "our," and "us" refers to National Storage Affiliates Trust and its consolidated subsidiaries, except where the context indicates otherwise. The Company intends to elect and qualify as a real estate investment trust ("REIT") for U.S. federal income tax purposes commencing with its taxable year ending December 31, 2015.
Through our controlling interest as the sole general partner of NSA OP, LP (our "operating partnership"), a Delaware limited partnership formed on February 13, 2013, we are focused on the ownership, operation, and acquisition of self storage properties in the United States. Pursuant to the Agreement of Limited Partnership (as amended, the "LP Agreement") of our operating partnership, our operating partnership is authorized to issue Class A Units ("OP units"), different series of Class B Units ("subordinated performance units"), and Long-Term Incentive Plan Units ("LTIP units"). We also own certain of our self storage properties through other consolidated limited partnership subsidiaries of our operating partnership, which we refer to as "DownREIT partnerships." The DownREIT partnerships issue equity ownership interests that are intended to be economically equivalent to our OP units ("DownREIT OP units") and subordinated performance units ("DownREIT subordinated performance units").
As of March 31, 2015, the Company was 100% owned by National Storage Affiliates Holdings, LLC ("Holdings"), an entity formed on February 13, 2013. The only assets of Holdings, as of March 31, 2015, were 126,400 OP units and 1,000 shares of the Company's common shares of beneficial interest, $0.01 par value per share ("common shares"). Immediately prior to the completion of our initial public offering on April 28, 2015, we redeemed the 1,000 common shares held by Holdings for no consideration.
Subsequent to March 31, 2015, the Company completed an initial public offering of 23,000,000 common shares, which included common shares issued pursuant to the exercise of the underwriters' option to purchase additional shares, and received net proceeds of approximately $273 million after deducting the underwriting discount and expenses of the initial public offering. In connection with the completion of the initial public offering, the Company also completed the formation transactions. These transactions are discussed further in Note 12.
The Company owned 225 self storage properties in 13 states with approximately 12.4 million rentable square feet in approximately 100,000 storage units as of March 31, 2015. These properties are managed with local operational focus and expertise by five participating regional operators ("PROs"). These PROs are SecurCare Self Storage, Inc. and its controlled affiliates ("SecurCare"), Kevin Howard Real Estate Inc., d/b/a Northwest Self Storage and its controlled affiliates ("Northwest"), Optivest Properties LLC and its controlled affiliates ("Optivest"), Guardian Storage Centers LLC and its controlled affiliates ("Guardian"), and Move It Self Storage and its controlled affiliates ("Move It").
