Capital and Accumulated Other Comprehensive Income (Loss)

(a) Allocations of Net Income and Net Losses to Partners

Except for special allocations to holders of profits interest units described below in Note 14(a) under the heading “Incentive Plan-Long-Term Incentive Units,” the Operating Partnership’s net income will generally be allocated to Digital Realty Trust, Inc. (the General Partner) to the extent of the accrued preferred return on its preferred units, and then to the General Partner and the Operating Partnership’s limited partners in accordance with the respective percentage interests in the common units issued by the Operating Partnership. Net loss will generally be allocated to the General Partner and the Operating Partnership’s limited partners in accordance with the respective common percentage interests in the Operating Partnership until the limited partner’s capital is reduced to zero and any remaining net loss would be allocated to the General Partner. However, in some cases, losses may be disproportionately allocated to partners who have guaranteed our debt. The allocations described above are subject to special allocations relating to depreciation deductions and to compliance with the provisions of Sections 704(b) and 704(c) of the Code, and the associated Treasury Regulations.

(1)	All series of preferred units do not have a stated maturity date and are not subject to any sinking fund or mandatory redemption provisions. Upon liquidation, dissolution or winding up, each series of preferred units will rank senior to Digital Realty Trust, Inc. common units and on parity with the other series of preferred units.

(2)

Except in limited circumstances, reflects earliest date that Digital Realty Trust Inc. may exercise its option to redeem the corresponding series of preferred stock, at a redemption price of $25.00 per share, plus accrued and unpaid dividends up to but excluding the date of redemption. The Operating Partnership is required to redeem the corresponding series of preferred units in the event that the General Partner redeems a series of preferred stock.


(3)	Liquidation preference is $25.00 per unit.


(4)	Distributions on preferred units are cumulative and payable quarterly in arrears.

(5)

Redeemed on April 5, 2017 for $25.01840 per unit, or a redemption price of $25.00 per unit, plus accrued and unpaid distributions up to but not including the redemption date of approximately $0.1 million in the aggregate. In connection with the redemption, the previously incurred offering costs of approximately $6.3 million were recorded as a reduction to net income available to common unitholders.

Limited partners have the right to require the Operating Partnership to redeem part or all of their common units for cash based on the fair market value of an equivalent number of shares of the General Partner’s common stock at the time of redemption. Alternatively, the General Partner may elect to acquire those common units in exchange for shares of the General Partner’s common stock on a one-for-one basis, subject to adjustment in the event of stock splits, stock dividends, issuance of stock rights, specified extraordinary distributions and similar events. Pursuant to authoritative accounting guidance, the Operating Partnership evaluated whether it controls the actions or events necessary to issue the maximum number of shares that could be required to be delivered under the share settlement of the limited partners’ common units and the vested incentive units. Based on the results of this analysis, the Operating Partnership concluded that the common units and incentive units of the Operating Partnership met the criteria to be classified within capital, except for certain common units issued to certain former DFT Operating Partnership unitholders in the DFT merger which are subject to certain restrictions and are not presented as permanent capital in the consolidated balance sheet.

The redemption value of the limited partners’ common units and the vested incentive units was approximately $887.0 million and $226.3 million based on the closing market price of Digital Realty Trust, Inc.’s common stock on December 31, 2017 and 2016, respectively.
