Asvalues and customers of the date hereof, our board of directors is not aware of any other such matter or businessthose communities we serve. In this regard, we are committed to be transacted at our Annual Meeting. If other matters requiringfostering a vote of the stockholders arise, the persons designated as proxies will vote the shares of common stock of the Company, par value $0.01 per share, represented by the proxies in accordance with their judgment on those matters.

Who is entitledsafe, inclusive, and equitable workplace that attracts and retains exceptional talent, enabling us to vote at the Annual Meeting?

        The record date for stockholders entitled to notice of, and to vote at, the Annual Meeting is March 7, 2018. At the close of business on that date, we had 135,346,517 shares of common stock outstanding and entitled to be voted at the Annual Meeting held by 11 stockholders of record. A quorum is required for our stockholders to conduct business at the Annual Meeting. The presence in person or by proxy of the holders of record of a majority of the shares of common stock entitled to vote at the Annual Meeting is necessary to constitute a quorum at the Annual Meeting. Each outstanding share of common stock is entitled to one vote. Dissenters' rights are not applicable to any of the matters being voted upon at the Annual Meeting.

        By granting a proxy, you authorize the persons named in the proxy to represent you and vote your shares at the Annual Meeting. Those persons will also be authorized to vote your shares to adjourn the Annual Meeting from time to time and to vote your shares at any adjournments or postponements of the Annual Meeting.

        Registered Stockholders.    If your shares are registered directly in your name with our transfer agent, Computershare Trust Company, N.A. ("Computershare"), you are considered the stockholder of record with respect to those shares, and the proxy materials were provided to you directly by us. As a stockholder of record, you have the right to grant your voting proxy directly to the individuals listed on the proxy card in one of the manners listed on the proxy card or to vote in person at the Annual Meeting.

        Beneficial Stockholders.    If your shares are held in a stock brokerage account or by a broker, bank, trustee or other nominee, you are considered the beneficial owner of shares held in "street name," and the proxy materials were forwarded to you by your broker, bank, trustee or other nominee, who is considered, with respect to those shares, the stockholder of record. As the beneficial owner, you have the right to direct your broker, bank, trustee or other nominee how to vote your shares using the methods prescribed by your broker, bank, trustee or other nominee on the voting instruction card you received with the proxy materials. Beneficial owners are also invited to attend the Annual Meeting. However, since you are not the stockholder of record, you may not vote your shares in person at the Annual Meeting unless you follow your broker's, bank's, trustee's or other nominee's procedures for obtaining a legal proxy.

What votes are required to approve each of the proposals?

        Proposal 1, the nominees for Class I director will be elected by a majority of the votes cast with respect to such director nominee's election. On October 28, 2016, the board of directors amended and restated the Company's by-laws to provide for the election of directors by a majority of the votes cast, except in the case of contested elections. The "majority of votes cast" means that the number of shares voted "for" a director nominee must exceed the number of votes cast "against" that director nominee's election. In accordance with our amended and restated by-laws, stockholders do not have the right to cumulate their votes for the election of directors.

        Proposal 2, the non-binding advisory vote approving executive compensation, will be determined by the affirmative vote of the holders of at least a majority of the outstanding shares of common stock

present in person or represented by proxy at the Annual Meeting and entitled to vote. As an advisory vote, this proposal is not binding. However, our board of directors and Compensation Committee will consider the outcome of the vote when making future compensation decisions for our executive officers.

        Proposal 3, the ratification of the selection of Deloitte as our independent registered public accounting firm for the fiscal year ending December 31, 2018, will be determined by the affirmative vote of the holders of at least a majority of the outstanding shares of common stock present in person or represented by proxy at the Annual Meeting and entitled to vote. The Audit Committee has sole and direct responsibility for the appointment, retention, termination, compensation, evaluation and oversight of the work of any independent registered public accounting firm engaged by the Company. The Audit Committee has already appointed Deloitte as our independent registered public accounting firm for the fiscal year ending December 31, 2018. In the event of a negative vote on the ratification, the Audit Committee may reconsider its appointment of Deloitte for 2018; however, the Audit Committee will consider the outcome of the vote when making appointments of our independent registered public accounting firm in future years. Even if the appointment is ratified, the Audit Committee, in its discretion, may direct the appointment of a different independent registered public accounting firm at any time during the year if the Audit Committee determines that such a change would be in the Company's and the stockholders' best interests.

How are broker non-votes and abstentions counted?

        The presence of a majority of the outstanding shares of common stock entitled to vote at the Annual Meeting, either in person or by proxy, will constitute a quorum. Shares of common stock represented by proxies at the meeting, including broker non-votes and those that are marked "ABSTAIN" will be counted as shares present for purposes of establishing a quorum. Because broker non-votes are not voted affirmatively or negatively, they will have no effect on the approval of any of the proposals, except where brokers may exercise their discretion on routine matters. A broker non-vote occurs when a broker or nominee holding shares for a beneficial owner votes on one proposal, but does not vote on another proposal because the broker or nominee does not have discretionary voting power and has not received instructions from the beneficial owner. Abstention and broker non-votes shall not be counted as votes cast with respect to a director nominee's election in Proposal 1. As to Proposals 2 and 3, shares represented by proxies that are marked "ABSTAIN" will have the effect of a vote against the proposal, while a broker non-vote will not have an effect on the outcome of any proposal other than Proposal 3. Only the ratification of the selection of our independent registered public accounting firm in Proposal 3 is considered a routine matter. Your broker will therefore not have discretion to vote on the "non-routine" matters set forth in Proposals 1 and 2 absent direction from you.

What happens if a director nominee does not get a majority vote?

        Following certification of the stockholder vote in an uncontested election, any incumbent director who did not receive a majority of the votes cast for his or her election shall promptly tender his or her resignation, contingent upon acceptance of such resignation by the board, to the Chairman of the board. The Chairman of the board shall inform the Nominating and Corporate Governance Committee of such tender of resignation, and the Nominating and Corporate Governance Committee shall consider such resignation and recommend to the board of directors whether to accept the tendered resignation or reject it or whether any other action should be taken. In deciding upon its recommendation, the Nominating and Corporate Governance Committee shall consider all relevant factors, including without limitation the qualifications of the director who has tendered his or her resignation and the director's contribution to the Company and the board. The board will act on the recommendation of the Nominating and Corporate Governance Committee no later than 90 days after

the certification of the stockholder vote and disclose the decision by filing a Form 8-K with the SEC. The board shall consider the factors considered by the Nominating and Corporate Governance Committee and such additional information and factors that the board deems relevant.

Can I vote in person at the Annual Meeting?

        For stockholders with shares registered in the name of a brokerage firm or bank or other similar organization, you will need to obtain a legal proxy from the broker, bank, trustee or other nominee that holds your shares before you can vote your shares in person at the Annual Meeting. For stockholders with shares registered directly in their names with Computershare, you may vote your shares in person at the Annual Meeting.

What do I need to do to attend the Annual Meeting in person?

        Space for the Annual Meeting is limited and admission will be on a first-come, first-served basis. Stockholders should be prepared to present (1) valid government photo identification, such as a driver's license or passport; and (2) beneficial stockholders holding their shares through a broker, bank, trustee or other nominee will need to bring proof of beneficial ownership as of March 7, 2018, the record date, such as their most recent account statement reflecting their stock ownership prior to March 7, 2018, a copy of the voting instruction card provided by their broker, bank, trustee or other nominee or similar evidence of ownership.

Can I vote by telephone or Internet?

        For beneficial stockholders with shares registered in the name of a broker, bank, trustee or other nominee, a number of brokerage firms and banks are participating in a program that offers telephone and Internet voting options. Stockholders should refer to the voting instruction card provided by their broker, bank, trustee or other nominee for instructions on the voting methods they offer. Stockholders of record with shares registered directly in their names with Computershare will be able to vote using the telephone and Internet. If your shares are held in an account at a broker, bank, trustee or other nominee participating in this program or registered directly in your name with Computershare, you may vote those shares by calling the telephone number specified on your proxy or accessing the Internet website address specified on your proxy instead of completing and signing the proxy itself. The giving of such a telephonic or Internet proxy will not affect your right to vote in person should you decide to attend the Annual Meeting. The telephone and Internet voting procedures are designed to authenticate stockholders' identities, to allow stockholders to give their voting instructions and to confirm that stockholders' instructions have been recorded properly. If you vote by the Internet or by telephone, you do not need to send in a proxy card or voting instruction form. The deadline for Internet and telephone voting will be 11:59 p.m., Eastern Time, on April 23, 2018.

How will my proxy be voted?

the ratification of Deloitte as the Company's independent registered public accounting firm for the year ending December 31, 2018. A stockholder's submission of a signed proxy will not affect his or her right to attend and to vote in person at the Annual Meeting.

How do I change or revoke my proxy?

        Any person signing a proxy in the form accompanying this proxy statement has the power to revoke it prior to the Annual Meeting or at the Annual Meeting prior to the vote pursuant to the proxy. A proxy may be revoked by a writing delivered to us stating that the proxy is revoked, by a subsequent proxy that is signed by the person who signed the earlier proxy and is delivered before or at the Annual Meeting, by voting again on a later date on the Internet or by telephone (only your latest Internet or telephone proxy submitted prior to the Annual Meeting will be counted) or by attendance at the Annual Meeting and voting in person. Please note, however, that if a stockholder's shares are held of record by a broker, bank, trustee or other nominee and that stockholder wishes to vote in person at the Annual Meeting, the stockholder must bring a legal proxy to the Annual Meeting.

Who will count and certify the votes?

        Representatives of Broadridge Investor Communication Solutions, Inc. ("Broadridge") and the staff of our corporate secretary and investor relations offices will count the votes and certify the election results. The results will be publicly filed with the SEC on a Form 8-K within four business days after the Annual Meeting.

How can I make a proposal or make a nomination for director for next year's annual meeting?
