ORGANIZATION AND NATURE OF OPERATIONS
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 for U.S. federal income tax purposes ("REIT") commencing with its taxable year ended 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 located within the top 100 metropolitan statistical areas ("MSAs") throughout 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").
The Company completed its initial public offering on April 28, 2015, pursuant to which it sold 20,000,000 shares of the Company's common shares of beneficial interest, $0.01 par value per share ("common shares"), at a price of $13.00 per share. As part of the offering, the Company granted the underwriters an option to purchase up to 3,000,000 additional common shares within thirty days after the offering. The underwriters exercised their option in full and, on May 18, 2015, purchased an additional 3,000,000 common shares. These transactions resulted in net proceeds to the Company of approximately $278.1 million, after deducting the underwriting discount and before additional expenses associated with the offering. The Company contributed the net proceeds from its initial public offering to our operating partnership in exchange for 23,000,000 OP units. OP Units are the economic equivalent of the Company's common shares and for each common share issued by the Company, our operating partnership issues a corresponding OP Unit to NSA in exchange for the contribution of the proceeds from the share issuances.
Prior to the completion of our initial public offering, the Company was 100% owned by National Storage Affiliates Holdings, LLC ("Holdings"), an entity formed on February 13, 2013. Holdings' only assets consisted of 126,400 OP units in our operating partnership which were acquired for cash of $0.6 million, and 1,000 common shares which were issued for nominal consideration on June 7, 2013. While our operating partnership was also formed on February 13, 2013, it did not commence operations until April 1, 2013. Holdings served as the general partner of our operating partnership until June 7, 2013 when the Company was appointed as the sole general partner. Due to the existence of common control by Holdings, the Company is deemed to have commenced its operations concurrently with the April 1, 2013 date when our operating partnership began its operations. 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.
The Company's predecessor for accounting purposes consists of SecurCare Portfolio Holdings, LLC and SecurCare Value Properties, Ltd. (collectively, "NSA Predecessor"), entities whose principal owner is the Company's chief executive officer. NSA Predecessor does not represent a single legal entity, but a combination of these two legal entities under common control prior to formation of the Company. NSA Predecessor owned and operated a total of 110 self storage properties, which are included in the accompanying NSA Predecessor financial statements, in California, Colorado, Georgia, Mississippi, North Carolina, Oklahoma, and Texas. As discussed in Note 5, NSA Predecessor contributed to the Company a total of 88 of NSA Predecessor's self storage properties, consisting of 23 self storage properties on June 10, 2013, and an additional 65 self storage properties that were contributed on April 1, 2014. For financial reporting purposes the contribution of all 88 self storage properties by NSA Predecessor was accounted for as a reorganization of entities under common control, whereby all 88 self storage properties were treated as if they were acquired on April 1, 2013 (the date our operating partnership's operations commenced). Of the 110 self storage properties owned by NSA Predecessor, 22 self storage properties did not meet the criteria for contribution to the Company and are excluded from the accompanying NSA financial statements. The historical carrying value of the net assets of NSA Predecessor as of April 1, 2013 is reflected in Note 5, along with a reconciliation to the net assets contributed and liabilities assumed for the 88 self storage properties contributed by NSA Predecessor. In addition, the 110 self storage properties owned by NSA Predecessor are reflected in the accompanying NSA Predecessor financial statements.
Where the "Company" is referenced in comparisons of financial results for any date prior to April 1, 2013, the financial information for such period relates solely to NSA Predecessor, notwithstanding "Company" or "NSA" being the reference.
The Company owned 277 self storage properties in 16 states with approximately 15.8 million rentable square feet in approximately 123,000 storage units as of December 31, 2015. These properties are managed with local operational focus and expertise by our 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"), Move It Self Storage and its controlled affiliates ("Move It"), and Arizona Mini Storage Management Company d/b/a Storage Solutions and its controlled affiliates ("Storage Solutions").
