Organization, Consolidation and Presentation of Financial Statements [Abstract] |
Organization | ORGANIZATION References herein to “Blackstone Mortgage Trust,” “Company,” “we,” “us” or “our” refer to Blackstone Mortgage Trust, Inc., a Maryland corporation, and its subsidiaries unless the context specifically requires otherwise. Blackstone Mortgage Trust is a real estate finance company that originates, acquires, and manages senior loans and other debt or credit-oriented investments collateralized by or relating to commercial real estate in North America, Europe, and Australia. Our portfolio is composed primarily of senior loans secured by high-quality, institutional assets located in major markets, and sponsored by experienced, well-capitalized real estate investment owners and operators. We finance our investments in a variety of ways, including borrowing under our credit facilities, issuing collateralized loan obligations, or CLOs, or single-asset securitizations, asset-specific financings, syndicating senior loan participations, and corporate financing, depending on our view of the most prudent financing option available for each of our investments. We are externally managed by BXMT Advisors L.L.C., or our Manager, a subsidiary of Blackstone Inc., or Blackstone, and are a real estate investment trust, or REIT, traded on the New York Stock Exchange, or NYSE, under the symbol “BXMT.” Our principal executive offices are located at 345 Park Avenue, 24th Floor, New York, New York 10154. We conduct our operations as a REIT for U.S. federal income tax purposes. We generally will not be subject to U.S. federal income taxes on our taxable income to the extent that we annually distribute all of our net taxable income to stockholders and maintain our qualification as a REIT. We also operate our business in a manner that permits us to maintain an exclusion from registration under the Investment Company Act of 1940, as amended. We are organized as a holding company and conduct our business primarily through our various subsidiaries.
