OTHER Given the multiple services that are provided to a Client by CGAM or its affiliates, or to others, including clients of CAL that may also invest in a Client, conflicts of interest will arise. When using services provided by CAL, or another CGAM affiliate, a Client should be aware of the conflicts that may arise, consult its own adviser(s), and satisfy itself that the arrangement is appropriate and in its continuing best interests. CGAM and its affiliates are not required to devote their full-time or attention to managing your assets. CGAM affiliates, including CAL, conduct other business and also provide investment services to others that can be competitive with the activities provided to you. In advising other accounts, CGAM affiliates, including CAL, give advice and make recommendations to such accounts, which can be the same, similar to or different from those rendered to you. Differing compensation arrangements with others create incentives for CGAM affiliates, including CAL, to favor such other clients. CGAM and CAL personnel may have more than one role. For example, certain CAL portfolio managers also serve as traders or research analysts. Further, certain CAL research analysts offer investment ideas for team-managed products. Personnel with multiple roles may have an incentive to favor certain accounts or responsibilities over others. CGAM has in place policies and procedures to address conflicts of interest or potential conflicts of interest. These policies and procedures are described throughout this brochure and include requirements that CGAM personnel act in the best interest of the Client. ASSETS UNDER MANAGEMENT As of December 31, 2023, CGAM had approximately $16.3 million total assets under management.
