Prologis, Inc. is a self-administered and self-managed REIT and is the sole general partner of Prologis, L.P. through which it holds substantially all of its assets. We operate Prologis, Inc. and Prologis, L.P. as one enterprise and, therefore, our discussion and analysis refer to Prologis, Inc. and its consolidated subsidiaries, including Prologis, L.P. We invest in real estate through wholly owned subsidiaries and other entities through which we co-invest with partners and investors (co-investment ventures). We have a significant ownership interest in the co-investment ventures, which are either consolidated or unconsolidated based on our level of control of the entity. Prologis, Inc. began operating as a fully integrated real estate company in 1997 and elected to be taxed as a REIT under the Internal Revenue Code of 1986, as amended (Internal Revenue Code or IRC). We believe the current organization and method of operation enable Prologis, Inc. to maintain its status as a REIT. Prologis, L.P. was also formed in 1997. We operate, manage and measure the operating performance of our properties on an owned and managed (O&M) basis. Our O&M portfolio includes our consolidated properties as well as properties owned by our unconsolidated co investment ventures, which we manage. We make operating decisions based on our total O&M portfolio as we manage the properties without regard to their ownership. Prologis, Inc. was incorporated in 1983 in Maryland and is based in San Francisco, California.
