in its entirety as follows:

ITEM 4. PURPOSE OF TRANSACTION

Item 4 of Schedule 13D is supplemented and superseded, as the case may be, as
follows:

On September 16, 2016, the Reporting Persons, FPA Funds Trust and FPA Hawkeye Fund, LLC (collectively, the FPA Parties) entered into
an agreement (the Agreement) with the Issuer pursuant to which during discussions between the FPA Parties and the Issuer regarding certain matters relating to the level of the Reporting Persons ownership of shares of the
Issuers Common Stock and certain corporate governance matters (the Discussions), the FPA Parties agreed not to purchase or acquire, directly or indirectly, any additional shares of Common Stock of the Issuer until the earlier of
(i) September 28, 2016 or (ii) 72 hours after the FPA Parties provide notice that the Discussions have terminated.

The foregoing description of the
Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Agreement, which is filed as Exhibit 99.1 to this Amendment No. 1, and is incorporated herein by reference.

Going forward, the Reporting Persons may have conversations with members of the Issuers management team and members of the Issuers Board of
Directors (the Board) regarding multiple topics, including, but not limited to, corporate governance and the composition of the Board, general business operations and strategic alternatives to promote long-term value for the benefit of
all shareholders. The Reporting Persons may engage in communications with one or more officers, members of the Board, representatives, shareholders of the Issuer and other relevant parties regarding the Issuers business and certain
initiatives, which could include one or more of the items in subsections (a) through (j) of Item 4 of Schedule 13D. The Reporting Persons may, at any time and from time to time, review or reconsider their position and/or change their purpose and/or
formulate plans or proposals with respect thereto.

The Reporting Persons continuously assess the Issuers business, financial condition, results of operations
and prospects, general economic conditions, other developments and additional investment opportunities. Depending on such assessments and in compliance with any applicable agreements, the Reporting Persons may acquire additional securities of the
Issuer or new securities of the Issuer, engage in any hedging or similar transactions with respect to the Issuers securities, or may determine to sell or otherwise dispose of all or some of the Issuers securities in the open market, as
applicable, in privately negotiated transactions, in transactions directly with the Issuer or otherwise. Such actions will depend upon a variety of factors, including, without limitation, current and anticipated future trading prices, the financial
condition, results of operations and prospects of the Issuer, alternative investment opportunities, general economic, financial market and industry conditions and other factors that the Reporting Persons may deem material to their investment
decision.
