|Noncontrolling Interest [Abstract]|
All of the limited partner equity interests in the Company's operating partnership not held by the Company are reflected as noncontrolling interests. Noncontrolling interests also include ownership interests in DownREIT partnerships held by entities other than the Company's operating partnership. NSA is the general partner of its operating partnership and is authorized to cause its operating partnership to issue additional partner interests, including OP units and subordinated performance units, at such prices and on such other terms as it determines in its sole discretion.
As of June 30, 2017 and December 31, 2016, units reflecting noncontrolling interests consisted of the following:
OP Units and DownREIT OP units
OP units in the Company's operating partnership are redeemable for cash or, at the Company's option, exchangeable for the Company's common shares of beneficial interest, $0.01 par value per share ("common shares") on a one-for-one basis, and DownREIT OP units are redeemable for cash or, at the Company's option, exchangeable for OP units in its operating partnership on a one-for-one basis, subject to certain adjustments in each case. The holders of OP units are generally not entitled to elect redemption until one year after the later of the closing of the Company's initial public offering or the issuance of the OP units. The holders of DownREIT OP units are generally not entitled to elect redemption until five years after the date of the contributor's initial contribution. Accordingly, these limited partner interests are included in noncontrolling interests within equity in the accompanying condensed consolidated balance sheets as of June 30, 2017 and December 31, 2016.
The increase in OP Units outstanding from December 31, 2016 to June 30, 2017 was due to the conversion of 828,881 LTIP units into OP units and the issuance of 473,533 OP units in connection with the acquisition of self storage properties, partially offset by the redemption of 1,153,518 OP units for common shares.
Subordinated Performance Units and DownREIT Subordinated Performance Units
Subordinated performance units may also, under certain circumstances, be convertible into OP units which are exchangeable for common shares as described above, and DownREIT subordinated performance units may, under certain circumstances, be exchangeable for subordinated performance units on a one-for-one basis. Subordinated performance units are only convertible into OP units after a two year lock-out period and then generally (i) at the holder’s election only upon the achievement of certain performance thresholds relating to the properties to which such subordinated performance units relate or (ii) at the Company's election upon a retirement event of a PRO that holds such subordinated performance units or upon certain qualifying terminations. The holders of DownREIT subordinated performance units are generally not entitled to elect redemption until at least five years after the date of the contributor's initial contribution.
The increase in subordinated performance units outstanding from December 31, 2016 to June 30, 2017 was due to the issuance of 300,043 subordinated performance units to an affiliate of Personal Mini (the Company's chairman and chief executive officer, Arlen D. Nordhagen, has a noncontrolling minority ownership interest in this affiliate of Personal Mini) and the issuance of 96,394 subordinated performance units in connection with the acquisition of self storage properties.
LTIP units are a special class of partnership interest in the Company's operating partnership that allow the holder to participate in the ordinary and liquidating distributions received by holders of the OP units (subject to the achievement of specified levels of profitability by the Company's operating partnership or the achievement of certain events). LTIP units may also, under certain circumstances, be convertible into OP units on a one-for-one basis, which are then exchangeable for common shares as described above.
LTIP units were first granted under the 2013 Long-Term Incentive Plan (the "2013 Plan"). Some of the granted LTIP units vested immediately or upon completion of the Company's initial public offering. Others vest upon the contribution of self storage properties or along a schedule at certain times through January 1, 2020. LTIP units do not have full parity with OP units with respect to liquidating distributions and may not receive ordinary distributions until such parity is reached pursuant to the terms of the LP Agreement. If such parity is reached under the LP Agreement, upon vesting, vested LTIP units may be converted into an equal number of OP units, and thereafter have all the rights of OP units, including redemption rights.
The decrease in LTIP units outstanding from December 31, 2016 to June 30, 2017 was due to the conversion of 828,881 LTIP units into 828,881 OP units, partially offset by the issuance of 219,299 compensatory LTIP units to employees, consultants and trustees.
The entire disclosure for noncontrolling interest in consolidated subsidiaries, which could include the name of the subsidiary, the ownership percentage held by the parent, the ownership percentage held by the noncontrolling owners, the amount of the noncontrolling interest, the location of this amount on the balance sheet (when not reported separately), an explanation of the increase or decrease in the amount of the noncontrolling interest, the noncontrolling interest share of the net Income or Loss of the subsidiary, the location of this amount on the income statement (when not reported separately), the nature of the noncontrolling interest such as background information and terms, the amount of the noncontrolling interest represented by preferred stock, a description of the preferred stock, and the dividend requirements of the preferred stock.
