Q:
What is a broker non-vote?

A:
If you are a beneficial owner whose shares are held of record by a broker, you must instruct the broker how to vote your shares. If you do not provide voting instructions, your shares will not be voted on any proposal on which the broker does not have discretionary authority to vote. This is called a "broker non-vote." In these cases, the broker can register your shares as being present at the meeting for purposes of determining the presence of a quorum but will not be able to vote on those matters for which specific authorization is required under the rules of the New York Stock Exchange (NYSE). If you are a beneficial owner whose shares are held of record by a broker, your broker has discretionary voting authority under NYSE rules to vote your shares on the proposal to ratify the selection of Ernst & Young LLP even if the broker does not receive voting instructions from you. However, your broker does not have discretionary authority to vote on the election of directors, on the 2016 Plan or on the advisory vote on executive compensation without instructions from you, in which case a broker non-vote will occur and your shares will not be voted on these matters.
Q:

A:
Under our By-laws and our Corporate Governance Guidelines, directorsnominees for director must be elected by a majority of the votes cast in uncontested elections, such as the election of directors at the meeting. This means that the number of votes cast "for" a director nominee must exceed the number of votes cast "against" that nominee. Abstentions and broker non-votes are not counted as votes "for" or "against" a director nominee and therefore have no impact on the outcome of director elections. Any nominee who does not receive a majority of votes cast "for" his or her
