(1)For the above noted subsidiaries, our partnership has entered into voting arrangements to provide our partnership with the ability to direct the relevant activities of the investee. Our partnership controls these investees given that our partnership is exposed, or has rights, to variable returns from its involvement with the investee and has the ability to affect those returns through its power over the investee. Our partnership exercises judgment to determine the level of variability that will achieve control over an investee, particularly in circumstances where our partnership’s voting interest differs from its ownership interest in an investee. The following were considered to determine whether our partnership controls these investees: the degree of power (if any) held by other investors, the degree of exposure to variability of each investor, the determination of whether any general partner removal rights are substantive and the purpose and design of the investee.
