We conduct our business through our wholly-owned subsidiary, IAS Operating Partnership LP. We are externally managed and advised by Invesco Advisers, Inc., our Manager, which is an indirect, wholly-owned subsidiary of Invesco Ltd. We elected to be taxed as a REIT for U.S. federal income tax purposes under the provisions of the Internal Revenue Code of 1986, as amended, or the Code, commencing with our taxable year ended December 31, 2009. To maintain our REIT qualification, we are generally required to distribute at least 90% of our REIT taxable income to our stockholders annually. See “Restrictions on Ownership and Transfer.” We operate our business in a manner that permits our exclusion from the definition of an “Investment Company” under the 1940 Act.
