Summary of Significant Accounting Policies [Abstract]

Use of Estimates – The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Significant items subject to such estimates and assumptions include the useful lives of fixed assets, allowances for doubtful accounts and deferred tax assets and the valuation of derivatives, real estate assets, acquired intangible assets and certain accruals.

Variable Interest Entities (VIEs) – We determine whether an entity is a VIE and, if so, whether it should be consolidated by utilizing judgments and estimates that are inherently subjective. The determination of whether an entity in which we hold a direct or indirect variable interest is a VIE is based on several factors, including whether the entity’s total equity investment at risk upon inception is sufficient to finance the entity’s activities without additional subordinated financial support. We make judgments regarding the sufficiency of the equity at risk based first on a qualitative analysis, and then a quantitative analysis, if necessary.

We analyze any investments in VIEs to determine if we are the primary beneficiary. In evaluating whether we are the primary beneficiary, we evaluate our direct and indirect economic interests in the entity. Determining which reporting entity, if any, is the primary beneficiary of a VIE is primarily a qualitative approach focused on identifying which reporting entity has both (1) the power to direct the activities of a VIE that most significantly impact such entity’s economic performance and (2) the obligation to absorb losses or the right to receive benefits from such entity that could potentially be significant to such entity. Performance of that analysis requires the exercise of judgment.

We consider a variety of factors in identifying the entity that holds the power to direct matters that most significantly impact the VIE’s economic performance including, but not limited to, the ability to direct financing, leasing, construction and other operating decisions and activities. In addition, we consider the rights of other investors to participate in those decisions, to replace the manager and to sell or liquidate the entity. We determine whether we are the primary beneficiary of a VIE at the time we become involved with a variable interest entity and reconsider that conclusion upon a reconsideration event. As of December 31, 2019, we had one unconsolidated entity that was considered a VIE for which we are not the primary beneficiary. Our maximum exposure to losses associated with this VIE is limited to our aggregate investment, which was approximately $30.2 million as of December 31, 2019.

Real Estate Assets

Real Estate Assets – Real estate assets are reported at cost. All capital improvements for the income-producing properties that extend their useful lives are capitalized to individual property improvements and depreciated over their estimated useful lives. Depreciation for real estate assets is generally provided on a straight-line basis over 40 years from the date the property was placed in service. Property improvements are depreciated on a straight-line basis over the life of the respective improvement ranging from 20 to 40 years from the date the components were placed in service. Leasehold improvements are depreciated over the lesser of 20 years or through the end of the respective life of the lease. Repairs and maintenance costs are expensed as incurred. For the year ended December 31, 2019, depreciation expense related to real estate assets and non-real estate assets was $118.9 million and $11.9 million, respectively, for a total of $130.8 million. For the year ended December 31, 2018, depreciation expense related to real estate assets and non-real estate assets was $101.2 million and $12.3 million, respectively, for a total of $113.5 million. For the year ended December 31, 2017, depreciation expense related to real estate assets and non-real estate assets was $90.1 million and $14.2 million, respectively, for a total of $104.3 million. We capitalize certain real estate development costs, including internal costs incurred in connection with development. The capitalization of costs during the construction period (including interest and related loan fees, property taxes and other direct and indirect project costs) begins when development efforts commence and ends when the asset is ready for its intended use. The capitalization of internal costs increases construction in progress recognized during development of the related property and the cost of the real estate asset when placed into service and depreciated over its estimated useful life. Capitalization of such costs, excluding interest, aggregated to $17.8 million, $17.4 million and $12.7 million for the years ended December 31, 2019, 2018 and 2017 respectively. Interest is capitalized during the period of development by applying our weighted average effective borrowing rate to the actual development and other capitalized costs paid during the construction period. Interest is capitalized until the property is ready for its intended use. Interest costs capitalized totaled $33.2 million, $26.8 million and $14.3 million for the years ended December 31, 2019, 2018 and 2017, respectively.

Impairment of Long-Lived Assets, Intangible Assets and Goodwill -

Impairment of Long-Lived Assets, Intangible Assets and Goodwill – We review our long-lived assets, intangible assets and equity method investments for impairment when events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. Recoverability of assets to be held and used is measured by comparison of the carrying amount to the future net cash flows, undiscounted and without interest, expected to be generated by the asset group. If the net carrying value of the asset group exceeds the value of the undiscounted cash flows, the fair value of the asset group is assessed and may be considered impaired. An impairment loss is recognized based on the excess of the carrying amount of the impaired asset over its fair value. For the year ended December 31, 2019, we recognized a $11.5 million impairment loss related to the write-down of certain data center assets and equipment in one of our Dulles, Virginia data centers. The Dulles campus has two data center buildings and we initiated a plan in the fourth quarter of 2019 to abandon one of the buildings and relocate customers from the smaller and older facility being abandoned to the newer facility in an effort to better optimize our operating cost structure. The impairment loss is included within the “Transaction, integration and impairment costs” line item of the consolidated statements of operations. For the year ended December 31, 2018, we recognized $8.8 million of impairment losses related to certain product-related assets, which was included in the “Restructuring” line item of the consolidated statements of operations. For the year ended December 31, 2017, we recognized a $1.6 million impairment loss related to equipment used to support our cloud and managed service platform, which was included in the “Transaction, integration and impairment costs” line item of the consolidated statements of operations.

The fair value of goodwill is the consideration transferred in a business combination which is not allocable to identifiable intangible and tangible assets. Goodwill is subject to at least an annual assessment for impairment. In connection with the goodwill impairment evaluation that we performed as of October 1, 2019, we determined qualitatively that it is not more likely than not that the fair value of our one reporting unit was less than the carrying amount, thus we did not perform a quantitative analysis. As we continue to operate and assess our goodwill at the consolidated level for our single reporting unit and our market capitalization significantly exceeds our net asset value, further analysis was not deemed necessary as of December 31, 2019.

Cash and Cash Equivalents

Cash and Cash Equivalents – We consider all demand deposits and money market accounts purchased with a maturity date of three months or less at the date of purchase to be cash equivalents. Our account balances at one or more institutions periodically exceed the Federal Deposit Insurance Corporation (“FDIC”) insurance coverage and, as a result, there is concentration of credit risk related to amounts on deposit in excess of FDIC coverage. We mitigate this risk by depositing a majority of our funds with several major financial institutions. We also have not experienced any losses and do not believe that the risk is significant.

Revenue Recognition

Revenue Recognition – We derive our revenues from leases with customers for data center space which include lease components and nonlease revenue components, such as power, tenant recoveries, cloud and managed services. We adopted ASC Topic 842, Leases, the new accounting standard for leases, effective January 1, 2019 using the modified retrospective approach. In addition, we adopted ASC Topic 606, Revenue from Contracts with Customers, the new accounting standard for revenue from contracts with customers, effective January 1, 2018 using the modified retrospective approach. We have elected the available practical expedient to combine our nonlease revenue components that have the same pattern of transfer as the related operating lease component into a single combined lease component under ASC Topic 842. See the ‘Recently Adopted Accounting Standards’ section below for further details.

A description of each of our disaggregated revenue streams is as follows:

Rental Revenue

Our leases with customers are classified as operating leases and rental revenue is recognized on a straight-line basis over the customer lease term. Occasionally, customer leases include options to extend or terminate the lease agreements. We do not include any of these extension or termination options in a customer’s lease term for lease classification purposes or recognizing rental revenue unless it is reasonably certain the customer will exercise these extension or termination options.

Rental revenue also includes revenue from power delivery on fixed power arrangements, whereby customers are billed and pay a fixed monthly fee per committed available amount of connected power. These fixed power arrangements require us to provide a series of distinct services and to stand ready to deliver the power over the contracted term which is co-terminus with the lease. Customer fixed power arrangements have the same pattern of transfer over the lease term as the lease component and are therefore combined with the lease component to form a single lease component that is recognized over the term of the lease on a straight line basis.

In addition, rental revenue includes straight line rent. Straight line rent represents the difference in rents recognized during the period versus amounts contractually due pursuant to the underlying leases and is recorded as deferred rent receivable/payable in the consolidated balance sheets. For lease agreements that provide for scheduled rent increases, rental income is recognized on a straight-line basis over the non-cancellable term of the leases, which commences when control of the space has been provided to the customer. The amount of the straight-line rent receivable on the balance sheets included in rents and other receivables, net was $38.7 million and $29.7 million as of December 31, 2019 and December 31, 2018, respectively.

Rental revenue also includes amortization of set-up fees which are amortized over the term of the respective lease as discussed below.

Variable Lease Revenue from Recoveries

Certain customer leases contain provisions under which customers reimburse us for power and cooling-related charges as well as a portion of the property’s real estate taxes, insurance and other operating expenses. Recoveries of power and cooling-related expenses relate specifically to our variable power arrangements, whereby customers pay variable monthly fees for the specific amount of power utilized at the current utility rates. Our performance obligation is to stand ready to deliver power over the life of the customer contract up to a contracted power capacity. Customers have the

flexibility to increase or decrease the amount of power consumed, and therefore sub-metered power revenue is constrained at contract inception. The reimbursements are included in revenue as recoveries from customers and are recognized each month as the uncertainty related to the consideration is resolved (i.e. we provide power to our customers) and customers utilize the power. Reimbursement of real estate taxes, insurance, common area maintenance, or other operating expenses are accounted for as variable payments under lease guidance pursuant to the practical expedient and are recognized as revenue in the period that the expenses are recognized. Variable lease revenue from recoveries discussed above, including power, common area maintenance or other operating costs, have the same pattern of transfer over the lease term as the lease component and are therefore combined with the lease component to form a single lease component. Variable lease revenue from recoveries is included within the “rental” line item of the statements of operations.

Other Revenue

Other revenue primarily consists of revenue from our cloud and managed service offerings as well as revenue earned from partner channel, management and development fees. We, through our TRS, may provide both our cloud product and use of our managed services to our customers on an individual or combined basis. In both our cloud and managed services offerings the TRS’s performance obligation is to provide services (e.g. cloud hosting, data backup, data storage or data center personnel labor hours) to facilitate a fully integrated information technology (“IT”) outsourcing environment over a contracted term. Although underlying services may vary, over the contracted term monthly service offerings are substantially the same and we account for the services as a series of distinct services in accordance with ASC Topic 606. Service fee revenue is recognized as the revenue is earned, which generally coincides with the services being provided. As we have the right to consideration from customers in an amount that corresponds directly with the value to the customer of the TRS’s performance of providing continuous services, we recognize monthly revenue for the amount invoiced.

With respect to the transaction price allocated to remaining performance obligations within our cloud and managed service contracts, we have elected to use the optional exemption provided by ASC Topic 606 whereby we are not required to estimate the total transaction price allocated to remaining performance obligations as we apply the “right-to-invoice” practical expedient. As described above, the nature of our performance obligation in these contracts is to provide monthly services that are substantially the same and accounted for as a series of distinct services. These contracts generally have a remaining term ranging from month-to-month to three years.

Management fees and other revenues are generally received from our unconsolidated affiliate properties as well as third parties. Management fee revenue is earned based on a contractual percentage of unconsolidated affiliate property revenue. Development fee revenue is earned on a contractual percentage of hard costs to develop a property. We recognize revenue for these services provided when earned based on the performance criteria in ASC Topic 606, with such revenue recorded in “Other” revenue on the consolidated statements of operations.

Advance Rents and Security Deposits

Advance Rents and Security Deposits – Advance rents, typically prepayment of the following month’s rent, consist of payments received from customers prior to the time they are earned and are recognized as revenue in subsequent periods when earned. Security deposits are collected from customers at the lease origination and are generally refunded to customers upon lease expiration.

Foreign Currency

Foreign Currency - The financial position of foreign subsidiaries is translated at the exchange rates in effect at the end of the period, while revenues and expenses are translated at average exchange rates during the period. Gains or losses from translation of foreign operations where the local currency is the functional currency are included as components of other comprehensive income (loss). Gains or losses from foreign currency transactions are included in determining net income (loss).

Segment Information

Segment Information – We manage our business as one operating segment and thus one reportable segment consisting of a portfolio of investments in multiple data centers.

Distribution Policy

Distribution Policy

To satisfy the requirements to qualify for taxation as a REIT, and to avoid paying tax on our income, we intend to continue to make regular quarterly distributions of all, or substantially all, of our REIT taxable income (excluding net capital gains) to our stockholders.

All distributions will be made at the discretion of our board of directors and will depend on our historical and projected results of operations, liquidity and financial condition, our REIT qualification, our debt service requirements, operating expenses and capital expenditures, prohibitions and other restrictions under financing arrangements and applicable law and other factors as our board of directors may deem relevant from time to time. We anticipate that our estimated cash available for distribution will exceed the annual distribution requirements applicable to REITs and the amount necessary to avoid the payment of tax on undistributed income. However, under some circumstances, we may be required to make distributions in excess of cash available for distribution in order to meet these distribution requirements and we may need to borrow funds to make certain distributions. If we borrow to fund distributions, our future interest costs would increase, thereby reducing our earnings and cash available for distribution from what they otherwise would have been.

The partnership agreement of the Operating Partnership requires the Operating Partnership to distribute at least quarterly 100% of our “available cash” (as defined in the partnership agreement) to the partners of the Operating Partnership, in accordance with the terms established for the class of partnership interests held by such partner. Furthermore, because QTS intends to continue to qualify as a REIT for tax purposes, QTS is required to make reasonable efforts to distribute available cash (a) to limited partners of the Operating Partnership so as to preclude any such distribution or portion thereof from being treated as part of a sale of property to the Operating Partnership by a limited partner under Section 707 of the Code or the regulations thereunder; provided, however, that neither of QTS nor the Operating Partnership shall have liability to a limited partner under any circumstances as a result of any distribution to a limited partner being

so treated, and (b) to QTS, as general partner, in an amount sufficient to enable QTS to make distributions to its stockholders that will enable QTS to (1) satisfy the requirements for qualification as a REIT under the Code and the regulations thereunder, and (2) avoid any federal income or excise tax liability. Consistent with the partnership agreement, we intend to continue to distribute quarterly an amount of our available cash sufficient to enable QTS to pay quarterly dividends to its stockholders in an amount necessary to satisfy the requirements applicable to REITs under the Code and to eliminate federal income and excise tax liability.

Recently Adopted Accounting Standards

Recently Adopted Accounting Standards

Revenue from Contracts with Customers

In May 2014, the FASB issued guidance codified in ASC Topic 606, Revenue from Contracts with Customers, which supersedes the former revenue recognition requirements in ASC Topic 605, Revenue Recognition. Under this new guidance, entities should recognize revenues to depict the transfer of promised goods or services to customers in an amount that reflects the consideration the entity expects to receive in exchange for those goods or services. The standard establishes a five-step model framework which recognizes revenue as an entity transfers control of goods or services to the customer and requires enhanced disclosures. We adopted ASC Topic 606 effective January 1, 2018, and elected the modified retrospective transition approach, which applied the provisions of the new guidance at the effective date without adjusting comparative periods presented. The adoption did not result in a cumulative catch-up adjustment to opening equity and does not change the recognition pattern of our operating revenues accounted for under ASC Topic 606.

Leases

In February 2016, and further amended in 2018, the FASB issued ASC Topic 842, Leases, which supersedes the former lease guidance in ASC Topic 840, Leases. The new standard increases transparency and comparability most significantly by requiring the recognition by lessees of right-of-use (“ROU”) assets and lease liabilities on the balance sheets for those leases classified as operating leases. Under the standard, disclosures are required to meet the objective of enabling users of financial statements to assess the amount, timing, and uncertainty of cash flows arising from leases.

We adopted ASC Topic 842 effective January 1, 2019 using the modified retrospective approach, which applied the provisions of the new guidance at the effective date without adjusting comparative periods presented. We elected a package of practical expedients permitted under the transition guidance within the new standard which allowed us to not reassess (i) whether expired or existing contracts contain a lease under the new standard, (ii) the lease classification for existing leases or (iii) whether previously-capitalized initial direct costs would qualify for capitalization under the new standard. We did not elect the hindsight practical expedient which permits entities to use hindsight in determining the lease term and assessing impairment.

The adoption of ASC Topic 842 impacted our consolidated balance sheets with the recognition of existing operating leases as lessee resulting in $62.9 million of ROU assets and $70.7 million of lease liabilities recorded as of January 1, 2019. We also recognized a $1.8 million cumulative effect adjustment to retained earnings. The adjustment to retained earnings was due to an impairment of certain ROU assets associated with vacant office space for which we are a lessee and assumed in a prior acquisition. See the table below for the impact of adoption of the lease standard on our consolidated balance sheets as of January 1, 2019 (in thousands):


	As Previously		New Lease Standard
	Reported		Adjustment		As Adjusted
Operating lease right-of-use assets	$	—	$	62,922	$	62,922
Operating lease liabilities		—		70,657		70,657
Deferred rent payable		5,922		(5,922)		—

As lessor, accounting for our leases remained largely unchanged from ASC Topic 840. The new lease standard more narrowly defines initial direct costs as only costs that are incremental to origination of a lease (i.e. costs that would not have been incurred had the lease not been obtained). We did not historically capitalize non-incremental costs, therefore this change did not have an impact on the accounting for initial direct costs in the consolidated financial statements.

Additionally, from a lessor perspective, we elected a practical expedient which allows lessors to combine nonlease components with the related lease components if both the timing and pattern of transfer are the same for the nonlease component(s) and related lease component, and the lease component would be classified as an operating lease. The single combined component is accounted for under ASC Topic 842 if the lease component is the predominant component and is accounted for under ASC Topic 606 if the nonlease components are the predominant components. Lessors are permitted to apply the practical expedient to all existing leases on a retrospective or prospective basis. We elected the practical expedient to combine our lease and nonlease components that meet the defined criteria and account for the combined lease component under ASC Topic 842.

New Accounting Pronouncements

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement. The amendments in ASU 2018-13 eliminate the requirements to disclose the amount and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, valuation processes for Level 3 fair value measurements, and policy for timing of transfers between levels. ASU 2018-13 also provides clarification in the measurement uncertainty disclosure by explaining that the disclosure is to communicate information about the uncertainty in measurement as of the reporting date. In addition, ASU 2018-13 added the following requirements: changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements held at the end of the reporting period; and range and weighted average of significant unobservable inputs used in Level 3 fair value measurements. Finally, ASU 2018-13 updated language to further encourage entities to apply materiality when considering de minimus determination for disclosure requirements. The guidance will be applied retrospectively for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years, with the exception of amendments to changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used for Level 3 fair value measurements, and the narrative description of measurement uncertainty which will be applied prospectively. Early adoption is permitted. We do not expect provisions of the standard will have a material impact on our consolidated financial statements.

In August 2018, the FASB issued ASU 2018-15, Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement that is a Service Contract. The amendments in ASU 2018-15 clarifies that implementation costs incurred by customers in cloud computing arrangements are deferred if they would be capitalized by customers in the software licensing arrangements under the internal-use software guidance. ASU 2018-15 also clarifies that any capitalized costs should not be recorded to “Depreciation and amortization” in the Consolidated Statements of Operations for costs after adoption. ASU 2018-15 is effective for the Company beginning January 1, 2020 and provides for the alternative to adopt the ASU (a) prospectively only for new costs incurred after the adoption date or (b) by adjusting existing costs to comply with this standard, including the requirement to present the amortization of costs outside “Depreciation and amortization”. We plan to adopt this ASU prospectively to all new implementation costs incurred after adoption. We do not expect this standard will have a material impact on our net income. However, this standard will likely result in certain expenses currently recognized as non-real estate depreciation being recognized as general and administrative or operating expense in future periods.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, and subsequent amendments to the guidance: ASU 2018-19 in November 2018, ASU 2019-04 in April 2019, ASU 2019-05 in May 2019, and ASUs 2019-10 & 2019-11 in November 2019. The standard, as amended, requires entities to use a new impairment model based on current expected credit losses (“CECL”) rather than incurred losses. The CECL model is designed to capture expected credit losses through the establishment of an allowance account, which will be presented as an offset to the amortized cost basis of the related financial asset. The guidance is effective for interim and annual periods beginning after December 15, 2019. Early adoption is permitted. As the majority of our revenue is generated from operating leases which are governed under ASC Topic 842, we do not currently expect the provisions of the standard will have a material impact on our consolidated financial statements.

In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. The amendments in this ASU simplify the accounting for income taxes by removing certain exceptions and adding some requirements regarding franchise (or similar) tax, step-ups in a business combination, treatment of entities not subject to tax and when to apply enacted changes in tax laws. This ASU is effective for fiscal years beginning after December 15, 2020 and interim periods within those fiscal years. The amendments related to changes in ownership of foreign equity method investments or foreign subsidiaries should be applied on a modified retrospective basis through a cumulative-effect adjustment to retained earnings as of the beginning of the fiscal year of adoption. The amendments related to franchise taxes that are partially based on income should be applied on either a retrospective basis for all periods presented or a modified retrospective basis through a cumulative-effect adjustment to retained earnings as of the beginning of the fiscal year of adoption. All other amendments should be applied on a prospective basis. Early adoption is permitted. We are currently assessing the impact of this standard on our consolidated financial statements.

We determined all other recently issued accounting pronouncements will not have a material impact on our consolidated financial statements or do not materially apply to our operations.
