Under the definition of “beneficial ownership” in Rule 13d-3 under the Act, it is also possible that the individual general partners, executive officers, and members of the foregoing entities might be deemed the “beneficial owners” of some or all of the Securities insofar as they may be deemed to share the power to direct the voting or disposition of the Securities.  Neither the filing of this Schedule nor any of its contents shall be deemed to constitute an admission that any of such individuals is, for any purpose, the beneficial owner of any of the Securities, and such beneficial ownership is expressly disclaimed.

The calculation of percentage of beneficial ownership in item 11 of pages 2 - 5 was derived from the Issuer’s website in which the Issuer stated that the number of shares of its common stock outstanding as of January 2, 2018 was 79,725,187 shares.

Item 6.      Ownership of More than Five Percent on Behalf of Another Person.

SIM serves as general partner and investment manager to certain investment limited partnerships that have the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, the Securities.  Other than as reported in this Schedule, no investment limited partnership’s holdings exceed five percent of the Issuer’s common stock.
