Prior to the Management Internalization, AH LLC exercised control over the Company through the contractual rights provided to the Advisor through an advisory management agreement. Accordingly, the contribution of certain properties by AH LLC to the Company prior to the Management Internalization have been deemed to be transactions between entities under common control, and as such, the accounts relating to the properties contributed have been recorded by us as if they had been acquired by us on the dates such properties were acquired by AH LLC (see Note 10).
