Point72 Asset Management, Point72 Capital Advisors Inc. and Mr. Cohen (collectively, the “Reporting Persons”) expressly disclaim beneficial ownership of securities directly beneficially owned by any person or entity other than, to the extent of any pecuniary interest therein, the various accounts under the Reporting Persons’ management and control.

(b) The address of the principal business office of Point72 Asset Management, Point72 Capital Advisors Inc. and Mr. Cohen is 72 Cummings Point Road, Stamford, CT 06902.

The order prohibited Mr. Cohen from being associated in a supervisory capacity with any investment adviser, broker or dealer until December 31, 2017.

Item 3. Source and Amount of Funds or Other Consideration.

The Portfolio Funds expended an aggregate of approximately $28,729,171 of investment capital to purchase the 2,983,825 shares of Common Stock reported hereby. Such transactions were effected in open market purchases in the ordinary course of business and are held by the Portfolio Funds in commingled margin accounts, maintained at Goldman Sachs & Co., Credit Suisse First Boston, Morgan Stanley & Co. and JPMorgan, which may extend margin credit to the Portfolio Funds as and when required to open or carry positions in the margin accounts, subject to applicable federal margin regulations, stock exchange rules and credit policies. In such instances, the positions held in the margin accounts are pledged as collateral security for the repayment of debit balances in the account. The margin accounts may from time to time have debit balances. Since other securities are held in the margin accounts, it is not possible to determine the amounts, if any, of margin used to purchase the shares of Common Stock reported herein.

Item 4. Purpose of Transaction.

The shares of Common Stock subject to this Schedule 13D were acquired for investment purposes, in the ordinary course of business, and not with the purpose nor with the effect of changing or influencing the control or management of the Issuer and without any agreement with any third party to act together for the purpose of acquiring, holding, voting or disposing of equity securities of the Issuer.

As part of the Reporting Persons’ continuing evaluation of, and preservation of the value of the Portfolio Funds’ investment in the Common Stock of the Issuer, the Reporting Persons may from time to time (i) engage in discussions with certain persons, including, without limitation, management or representatives, the Issuer’s board of directors, other shareholders of the Issuer and other relevant parties, concerning matters with respect to the investment in the Common Stock, including, without limitation, the business, operations, governance, management, strategy and future plans of the Issuer and (ii) write letters to, and respond to inquiries from, various parties including, without limitation, the Issuer’s board of directors, management or representatives, other shareholders and other persons or entities regarding the Issuer’s affairs.

Page 6 of 10

Depending on various factors, including, the Issuer’s financial position and strategic direction, the outcome of the matters referenced above, actions taken by the board of directors, price levels of the Common Stock, other available investment opportunities, conditions in the securities markets and general economic and industry conditions, the Reporting Persons may in the future take such actions with respect to the Portfolio Funds and/or other investment funds managed by one or more of the Reporting Persons with respect to the Issuer as they deem appropriate, including changing their current intentions, with respect to any or all matters referred to in this Item 4 of Schedule 13D and may, from time to time, cause the Portfolio Funds and/or other investment funds managed by one or more of the Reporting Persons to acquire additional Common Stock, dispose of some or all of their Common Stock, engage in short-selling, hedging or similar transactions with respect to the Common Stock, and/or continue to hold Common Stock. Except as set forth herein, or as would occur upon completion of any of the matters discussed herein, the Reporting Persons have no present plan or proposal that would relate to or result in any of the matters set forth in subparagraphs (a)-(j) of Item 4 of Schedule 13D.

Item 5. Interest in Securities of the Issuer.

(a) As of the close of business on March 19, 2018, the Reporting Persons beneficially owned an aggregate of 2,983,825 shares of Common Stock, representing approximately 20.0% of the shares of Common Stock outstanding. This increase in the percentage of shares of Common Stock owned by the Reporting Persons resulted not from acquisitions of Common Stock by the Reporting Persons (or the Portfolio Funds) but a decrease in the number of shares of Common Stock outstanding as a result of the Issuer’s repurchase program, as more fully described in the Issuer’s Annual Report on Form 10-K filed with the Securities and Exchange Commission on March 15, 2018 (the “Issuer 10-K”). The percentages used herein are based upon 14,900,452 shares of Common Stock reported to be outstanding, as of March 9, 2018, by the Issuer in the Issuer 10-K.

Point72 Asset Management, Point72 Capital Advisors Inc. and Mr. Cohen own directly no shares of Common Stock. Pursuant to an investment management agreement, Point72 Asset Management maintains investment and voting power with respect to the securities held by certain investment funds it manages. Point72 Capital Advisors Inc. is the general partner of Point72 Asset Management. Mr. Cohen controls Point72 Capital Advisors Inc. By reason of the provisions of Rule 13d-3 of the Act, as amended, each of Point72 Asset Management, Point72 Capital Advisors Inc. and Mr. Cohen may be deemed to beneficially own 2,983,825 shares of Common Stock (constituting approximately 20.0% of the shares of Common Stock outstanding).

(b) None of the Reporting Persons has sole power to vote or direct the vote or sole power to dispose or direct the disposition of shares of Common Stock.

Page 7 of 10

(i) Point72 Asset Management has shared power to vote or direct the vote and shared power to dispose or direct the disposition of the 2,983,825 shares of Common Stock, constituting 20.0% of such class of securities;

(ii) Point72 Capital Advisors Inc. has shared power to vote or direct the vote and shared power to dispose or direct the disposition of the 2,983,825 shares of Common Stock, constituting 20.0% of such class of securities; and

(c) None of the Reporting Persons or the Portfolio Funds engaged in transactions in shares of Common Stock during the past 60 days.

(d) No person other than the Reporting Persons is known to have the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, the shares of Common Stock directly beneficially owned by the Portfolio Funds.

(e) Not applicable.

Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer.

Other than as described herein, there are no contracts, arrangements, understandings or relationships (legal or otherwise) between the Reporting Persons and any other person with respect to the securities of the Issuer.

The Portfolio Funds may, from time to time, enter into and dispose of cash-settled equity swaps, contracts or other similar derivative contracts with one or more counterparties that are based upon the value of shares of Common Stock, which transactions may be significant in amount. The profit, loss and/or return on such contracts may be wholly or partially dependent on the market value of the shares of Common Stock, the relative value of shares of Common Stock in comparison to one or more other financial instruments, indexes or securities, a basket or group of securities in which shares of Common Stock may be included, or a combination of any of the foregoing. The Portfolio Funds currently have short exposure to an aggregate of 11,388 shares of Common Stock through such contracts. In addition to the shares of Common Stock reported herein, the Portfolio Funds currently have long exposure to an aggregate of 1,600 shares of Common Stock through such contracts. These contracts do not give the Reporting Persons, or the Portfolio Funds, direct or indirect voting, investment or dispositive control over any securities of the Issuer. Accordingly, the Reporting Persons disclaim any beneficial ownership in any securities that may be referenced in such contracts or that may be held from time to time by any counterparties to such contracts.
