 entities, receives all of his compensation from Calamos Advisors. He has entered into an employment agreement that provides for compensation in the form of an annual base salary and an annual bonus, both components payable in cash. Similarly, Mr. Calamos is eligible for Calamos Advisors’ Long-Term Incentive ("LTI") program. As of October 31, 2024, R. Matthew Freund, John Hillenbrand, Eli Pars, Jon Vacko and Joe Wysocki, and Chuck Carmody receive all of their compensation from Calamos. Compensation for portfolio management team members includes a competitive base salary, and an annual cash bonus (driven by investment, company, and individual performance). Portfolio managers are also eligible for Calamos Advisors' Long-Term Incentive ("LTI") program, which is an incentive award vesting over time that reflects appreciation and depreciation in the value of both the funds managed by such professional and the company generally. LTI awards granted in 2024 vest on a three-year schedule (25% on or about the first anniversary of the award grant, 25% on or about the second anniversary of the award grant, and 50% on or about the third anniversary of the award grant). Each investment team LTI award will be allocated as follows: (i) 33.3% to track the value of the associate's managed strategies, (ii) 33.3% to track the Calamos strategy of the associate's choice, and (iii) 33.3% to track the value of the firm; all over the vesting period. This compensation structure considers annually the performance of the various strategies managed by the Portfolio Managers, among other factors, including, without limitation, the overall performance of the firm. At October 31, 2024, each portfolio manager beneficially owned (as determined pursuant to Rule 16a-1(a)(2) under the Exchange Act) shares of the Fund having value within the indicated dollar ranges.
