Item 5.

Interest in Securities of the Issuer

(a) - (b) The MHC Mutual Conversion Fund Group beneficially owns 751,308 shares of Common Stock, which represents 6.2% 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 set forth in this Schedule 13D, by (ii) the 12,208,593 shares of Common Stock outstanding as of May 4, 2017, as reported in the Issuer's quarterly report on Form 10-Q filed with the Securities and Exchange Commission on May 9, 2017.
