At the meeting, the Unitholders also approved: (1) the ratification of the appointment of PricewaterhouseCoopers LLP as the Partnership’s independent registered public accounting firm for the Partnership’s 2021 fiscal year; (2) the Partnership’s Amended and Restated 2018 Restricted Unit Plan; and (3) an advisory resolution approving executive compensation (commonly referred to as “Say-on-Pay”).
