In tabulating the voting result, abstentions and, if applicable, broker non-votes are not counted as votes “FOR” or “AGAINST” the proposal. An abstention will, however, be counted as entitled to vote on a proposal and will, therefore, have the effect of a vote “AGAINST.” Applying this standard, the percentage in favor of the shareholder proposal is calculated by dividing the number of FOR votes by the sum of the number of FOR, AGAINST and ABSTAIN votes.
