service on our Board and committees of our Board. In March 2020, following analysis of market research and advice from its compensation consultant, our Board adopted the non-employee director compensation policy, which became effective on April 7, 2020. Following review of market research and advice from its compensation consultant, our Board amended our non-employee director compensation policy, effective on February 16, 2023 and most recently, effective July 1, 2024. Cash Compensation Under the non-employee director compensation policy, we pay each of our non-employee directors a cash retainer for service on our Board and committees of our Board. Effective July 1, 2024, our Lead Independent Director also receives an additional cash retainer. These retainers will be payable in arrears in four equal quarterly installments on the last day of each fiscal quarter in which the service occurred, provided that the amount of such payment will be prorated for any portion of such quarter that the director is not serving on our Board. Non-employee directors are eligible to receive cash compensation as follows:
