Appendix
Net Operating Income (“NOI”) and Cash NOI – NOI, and cash NOI are supplemental measures for the operating performance of the Company’s portfolio. NOI is operating revenues less operating expenses adjusted for items such as depreciation and amortization, general and administrative expenses, transaction costs from unsuccessful deals and business combinations and litigation expenses. Cash NOI is NOI less straight-line rents and above and below market rent amortization.
NRSF Held for Development
Represents incremental data center capacity that may be constructed in existing facilities that requires significant capital investment in order to develop new data center facilities. The estimates are based on current construction plans and expectations regarding entitlements, and they are subject to change based on current economic conditions, final zoning approvals, and the supply and demand of the market. The estimated NRSF for new development projects is based on the entire building size. NRSF placed into service may change depending on the final construction and utilization of the built space.
NRSF Under Construction
Represents NRSF for which substantial activities are ongoing to prepare the property for its intended use following development. The NRSF reflects management’s estimate of engineering drawings and required support space and is subject to change based on final demising of space. TKD estimated development costs include two components: 1) general construction to ready the NRSF as data center space and 2) power, cooling and other infrastructure to provide the designed amount of power capacity for the project. Following development completion, incremental capital, referred to as Deferred Expansion Capital, may be invested to support existing or anticipated future customer utilization of NRSF within our operating data centers.
NRSF Pre-Construction
Represents NRSF for which the projects are in the design and permitting stage. Construction will commence upon receipt of the applicable permits. The estimated completion dates are subject to change based on the timing of final design and permitting approvals.
Turn-Key Same-Store
Includes turn-key data center space that was leased or available to be leased to our colocation customers as of December 31, 2018, at each of our properties, and excludes powered shell data center space, office and light-industrial space and space for which development was completed and became available to be leased after December 31, 2018. The turn-key same-store space as of December 31, 2018, is 1,972,441 NRSF. We track same-store on a computer room basis within each data center facility.
Stabilized and Pre-Stabilized NRSF
Data center projects and facilities that recently have been developed and are in the initial lease-up phase are classified as pre-stabilized NRSF until they reach 85% occupancy or have been in service for 24 months. Pre-stabilized projects and facilities become stabilized operating properties at the earlier of achievement of 85% occupancy or 24 months after development completion and are included in the stabilized operating NRSF.
