 elect five Class III directors, (ii) approve a non-binding, advisory vote on the compensation of the Company’s named executive officers, and (iii) ratify the selection by the Audit Committee of the Company’s Board of Deloitte & Touche LLP as the Company’s independent registered public accounting firm for the year ending December 31, 2025.

Election of each of the Class III directors will require the affirmative vote of the holders of a majority of the total shares of common stock for which votes are cast on the election of such nominee at the meeting, and votes withheld from any nominee for election as a director will have the effect of “against” votes. Approval of the non-binding, advisory vote on executive compensation and ratification of the selection by the Board’s Audit Committee of Deloitte & Touche LLP as the Company’s independent registered public accounting firm for the year ending December 31, 2025 will each require the votes cast in favor of such action to exceed the votes cast opposing the action. Any abstentions and broker “non-votes” will be counted as shares present or represented for purposes of determining the presence of a quorum for the meeting but will have no impact on the election of directors or on the other proposals described above.

Broker “non-votes” occur when a broker holding shares in “street name” does not vote on a given proposal because the broker does not have discretionary voting power and has not received instructions from the beneficial owner of such shares. Usually, this occurs when brokers holding stock in “street name” have not received voting instructions from clients, in which case the brokers (as holders of record) are generally permitted by the rules of the New York Stock Exchange to vote only on “discretionary” matters. Under the New York Stock Exchange's current rules, brokers will not be permitted to vote shares for which they have not received voting instructions on the election of the Class III directors (Proposal 1) or advisory approval of executive compensation (Proposal 2). However, under such rules, the proposed ratification of the selection by the Audit Committee of Deloitte & Touche LLP as the Company's independent registered public accounting firm for the year ending December 31, 2025 (Proposal 3) is considered a “discretionary” matter, and brokers will therefore generally be able to vote shares held in “street name” on such matter without receiving instructions from the beneficial holders of such shares.
