Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization	Organization Corporate Property Associates 17 – Global Incorporated, or CPA:17 – Global, and, together with its consolidated subsidiaries, we, us, or our, is a publicly owned, non-traded real estate investment trust, or REIT, that invests primarily in commercial real estate properties leased to companies both domestically and internationally. We were formed in 2007 and are managed by W. P. Carey Inc., or WPC, through one of its subsidiaries, or collectively our Advisor. As a REIT, we are not subject to U.S. federal income taxation as long as we satisfy certain requirements, principally relating to the nature of our income and the level of our distributions, among other factors. We earn revenue primarily by leasing the properties we own to single corporate tenants, predominantly on a triple-net leased basis, which requires the tenant to pay substantially all of the costs associated with operating and maintaining the property. Revenue is subject to fluctuation due to the timing of new lease transactions, lease terminations, lease expirations, contractual rent adjustments, tenant defaults, sales of properties, and changes in foreign currency exchange rates. Substantially all of our assets and liabilities are held by CPA:17 Limited Partnership, or the Operating Partnership, and at December 31, 2017, we owned 99.99% of general and limited partnership interests in the Operating Partnership. The remaining interest in the Operating Partnership is held by a subsidiary of WPC. At December 31, 2017, our portfolio was comprised of full or partial ownership interests in 411 properties, substantially all of which were fully-occupied and triple-net leased to 116 tenants, and totaled approximately 44.4 million square feet (unaudited). In addition, our portfolio was comprised of full or majority ownership interests in 38 operating properties, including 37 self-storage properties and one hotel property, for an aggregate of approximately 2.7 million square feet (unaudited). We operate in two reportable business segments: Net Lease and Self Storage. Our Net Lease segment includes our domestic and foreign investments in net-leased properties, whether they are accounted for as operating or direct financing leases. Our Self Storage segment is comprised of our investments in self-storage properties. In addition, we have investments in loans receivable, commercial mortgage-backed securities, or CMBS, one hotel, and certain other properties, which are included in our All Other category (Note 15). Our reportable business segments and All Other category are the same as our reporting units. We raised aggregate gross proceeds of approximately $2.9 billion from our initial public offering, which closed in April 2011, and our follow-on offering, which closed in January 2013. We have fully invested the proceeds from our initial and follow-on public offerings. In addition, from inception through December 31, 2017, $676.0 million of distributions to our shareholders were reinvested in our common stock through our Distribution Reinvestment Plan, or DRIP.
