We also operate healthcare-related facilities utilizing the structure permitted by the REIT Investment Diversification and Empowerment Act of 2007, which is commonly referred to as a “RIDEA” structure (the provisions of the Internal Revenue Code of 1986, as amended, or the Code, authorizing the RIDEA structure were enacted as part of the Housing and Economic Recovery Act of 2008). Our healthcare facilities operated under a RIDEA structure include our senior housing operating properties, or SHOP, and our integrated senior health campuses. We have originated and acquired secured loans and may also originate and acquire other real estate-related investments on an infrequent and opportunistic basis. We generally seek investments that produce current income; however, we have selectively developed, and may continue to selectively develop, healthcare real estate properties. We have elected to be taxed as a REIT for U.S. federal income tax purposes. We believe that we have been organized and operated, and we intend to continue to operate, in conformity with the requirements for qualification and taxation as a REIT under the Code.</span></div><div style="margin-top:8pt;text-indent:27pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">On October 1, 2021, Griffin-American Healthcare REIT III, Inc., or GAHR III, merged with and into a wholly-owned subsidiary, or Merger Sub, of Griffin-American Healthcare REIT IV, Inc., or GAHR IV, with Merger Sub being the surviving company, which we refer to as the REIT Merger, and our operating partnership, Griffin-American Healthcare REIT IV Holdings, LP, or GAHR IV Operating Partnership, merged with and into Griffin-American Healthcare REIT III Holdings, LP, or the Surviving Partnership, with the Surviving Partnership being the surviving entity, which we refer to as the Partnership Merger and, together with the REIT Merger, the Merger.
