This Schedule 13D relates to Common Stock of the Issuer purchased by the GP through the account of the Fund. The Fund may direct the vote and disposition of the 268,410 shares of Common Stock it holds directly.

Each of the persons identified in this Schedule 13D is referred to as a “Reporting Person” and, collectively, as the “Reporting Persons.” Each of the Reporting Persons is a party to that certain Joint Filing Agreement attached as Exhibit 1 to the original Schedule 13D, as filed with the Securities and Exchange Commission on September 25, 2013.

The Reporting Persons are filing this Schedule 13D jointly, as they may be considered a “group” under Section 13(d)(3) of the Act. However, neither the fact of this filing nor anything contained herein shall be deemed to be an admission by the Reporting Persons that such a group exists.

(b)         The principal place of business for each of the Reporting Persons is 100 Crescent Court, Suite 575, Dallas, TX 75201.

(c)         The principal occupation of Mr. Mewhinney is serving as the managing member of Clover. The principal business of Clover is acting as the general partner of the GP. The principal business of the GP is investment management. The principal business of the Fund is investing in securities.

(d)         During the last five years, none of the Reporting Persons have been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors).

(e)         During the last five years, none of the Reporting Persons have been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and, as a result of such proceeding, were or are subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.

(f)         The Fund, the GP and Clover are organized under the laws of the State of Texas. Mr. Mewhinney is a citizen of the United States of America.

As of the date of this Schedule 13D, the Fund had invested $4,477,625 (inclusive of brokerage commissions) in Common Stock of the Issuer. The source of these funds was the working capital of the Fund.

The MHC Mutual Conversion Fund Group purchased the Common Stock for investment purposes. The MHC Mutual Conversion Fund Group’s intent is to influence the policies of the Issuer and assert shareholder rights, with a goal of maximizing the value of the Common Stock. Consistent with its investment purpose, the MHC Mutual Conversion Fund Group has engaged and will continue to engage in communications with one or more officers of the Issuer and/or one or more members of the board of directors of the Issuer (the “Board”), and/or one or more representatives of the Issuer regarding the Issuer, including, but not limited to its business, management, operations, assets, capitalization, financial condition, governance, strategy and future plans.

The MHC Mutual Conversion Fund Group may purchase, sell or transfer Common Stock beneficially owned by it from time to time in public transactions depending on economic considerations and communications with the Issuer. Any such transactions may be effected at any time or from time to time subject to any applicable limitations imposed on the sale of the Common Stock by applicable law.

Except to the extent the foregoing may be deemed a plan or proposal, the Reporting Persons have no plans or proposals which relate to, or could result in, any of the matters referred to in paragraphs (a) through (j), inclusive, of the instructions to Item 4 of the 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.

(a) - (b) The MHC Mutual Conversion Fund Group beneficially owns 268,410 shares of Common Stock, which represents 6.6% of the Issuer’s outstanding shares of Common Stock. The percentage of beneficial ownership of the Reporting Persons, as reported in this Schedule 13D, was calculated by dividing (i) the total number of shares of Common Stock beneficially owned by the MHC Mutual Conversion Fund Group as of October 18, 2013, as set forth in this Schedule 13D, by (ii) the 4,038,006, shares of Common Stock outstanding as of September 20, 2013, according to the Issuer’s Form 10-K filed with the Securities and Exchange Commission on September 27, 2013.

The GP, in its capacity as investment manager and general partner to the Fund has power to vote the 268,410 shares of Common Stock and the power to dispose of the 268,410 shares of Common Stock held in the Fund. Clover, in its capacity as general partner of the GP and Mr. Mewhinney, as the managing member of Clover, may each be deemed to beneficially own the Common Stock held in the Fund.

(c)         Other than the Fund, none of the other Reporting Persons has effected any transactions in the Common Stock since the filing of the initial Schedule 13D. The Fund effected the following transactions:

The filing of this Schedule 13D shall not be construed as admission that the GP, Clover, or Mr. Mewhinney is for the purposes of Section 13(d) or 13(g) of the Act the beneficial owner of any of the 268,410 shares of Common Stock owned by the Fund. Pursuant to Rule 13d-4, the GP, Clover, and Mr. Mewhinney disclaim all such beneficial ownership.

(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 proceeds from the sale of, the Common Stock.

(e)         Not applicable.

With respect to the Fund, GP is entitled to (1) an allocation of a portion of profits, if any, and (2) a management fee based upon a percentage of total capital.

Other than the foregoing agreements and arrangements, and the Joint Filing Agreement, there are no contracts, arrangements, understandings or relationships among the persons named in Item 2 hereof and between such persons and any person with respect to any securities of the Issuer.
