Will my shares be voted if I dont return my proxy?
If your shares are registered directly in your name, your shares will not be voted if you do not vote over the Internet, by telephone, by
returning your proxy card or voting at the Annual Meeting. If your shares are held in street name by a bank, broker or other nominee, that person, as the record holder of your shares, is required to vote your shares according to your
instructions. Your bank, broker or other nominee will send you directions on how to vote those shares. Under applicable stock exchange rules, if you do not give instructions to your bank, broker or other nominee, it will still be able to vote your
shares with respect to certain discretionary items, such as the ratification of the appointment of RSM US LLP (RSM) as our independent registered public accounting firm, but will not be allowed to vote your shares with
respect to certain non-discretionary items, such as the election of directors, the approval, on an advisory basis, of the compensation of our named executive officers and the approval, on an
advisory basis, of the frequency of future advisory votes on the compensation of our named executive officers. In the case of non-discretionary items, shares for which your bank, broker or other
nominee does not receive voting instructions will be treated as broker non-votes.
