but with no voting choice selected for a non-routine proposal, the result is a broker non-vote. Broker non-votes are counted as present and entitled to vote for purposes of determining a quorum at the meeting but are not considered votes cast and will have no impact on non-routine matters. Accordingly, we do not expect there to be any broker non-votes for Proposal 2 and broker non-votes will not be counted with respect to Proposals 1 and 3. Q: What constitutes a quorum? A: The holders of a majority of the outstanding Class A, Class B and Class C shares, considered together, entitled to vote and present in person or by proxy at the PAGP Annual Meeting shall constitute a quorum. Your shares will be counted as present at the PAGP Annual Meeting if: • you are present and vote at the meeting; or • you, or your broker if you are a beneficial owner of shares held in street name, have submitted a properly executed proxy. Executed proxies received but marked as abstentions and broker non-votes will be counted as present for purposes of determining the presence of a quorum. Q: What will I be voting on and what vote is required to approve the proposals discussed in this proxy statement? A: The proposals that will be voted upon and the required vote for approval of such proposals is set forth in the following table:
