CUSIP No.   20366P100		SCHEDULE 13D
This Amendment No. 1 (this “Amendment”) amends Items 1, 4, 5 and 7 of the Schedule 13D filed on January 25, 2013 (the “Original Schedule 13D” and together with Amendment No. 1, the “Schedule 13D”), by Ithan Creek Master Investors (Cayman) L.P. and Ithan Creek Investors USB, LLC  with respect to the common stock of Community Financial Shares, Inc. (the “Company”).  Except as specifically provided herein, this Amendment does not modify any of the information previously reported on the Original Schedule 13D.  Capitalized terms used in this Amendment and not otherwise defined herein shall have the same meanings ascribed to them in the Original Schedule 13D.
Item 1.	Security and Issuer
Item1 is hereby amended and restated as follows: This Schedule 13D relates to the common stock, no par value per share (the “Common Stock”), of Community Financial Shares, Inc. (the “Issuer”).  The principal executive offices of the Issuer are located at 357 Roosevelt Road, Glen Ellyn, Illinois 60137.
Item 4.	Purpose of Transaction
Item 4 is hereby amended and supplemented to add the following: On June 13, 2013, the stockholders of the Company approved an amendment to the Certificate of Designations for the Company’s Series C Preferred Stock to include conversion blockers that prevent a holder of the Series C Preferred Stock from converting shares of the Series C Preferred Stock into Common Stock to the extent (but only to the extent) that such conversion would result in the holder, or any of its affiliates, beneficially owning (as determined in accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended, and the rules and regulations promulgated thereunder) more than 9.9% or 4.9%, as applicable, of the Company’s outstanding Common Stock.  The amendment became effective upon the Company’s filing of the Amended and Restated Certificate of Designations for the Series C Preferred Stock with the Delaware Secretary of State on June 14, 2013.  Pursuant to the terms of the Amended and Restated Certificate of Designations for the Series C Preferred Stock, the 9.9% conversion blocker (the “9.9% Conversion Blocker”) is applicable to the Reporting Persons and their affiliates because Ithan LLC purchased shares of both Series C Preferred Stock and Series D Preferred Stock pursuant to the Securities Purchase Agreement.
Item 5.	Interest in Securities of the Issuer
Items 5(a) and (b) are hereby amended and restated as follows: (a) and (b)             As of the date hereof: (i)            Ithan LLC is the beneficial owner of 664,067 shares of Common Stock which are issuable upon conversion of shares of Series C Preferred Stock. Such shares represent beneficial ownership of 9.9% of the Common Stock, based on 6,043,688 shares of Common Stock issued and outstanding as of May 6, 2013.  The foregoing excludes (i) 843,033 shares of Common Stock issuable upon conversion of shares of Series C Preferred Stock held by Ithan LLC and (ii) 505,800 shares of Common Stock issuable upon conversion of shares of Series D Preferred Stock held by Ithan LLC because of the 9.9% Conversion Blocker and the Ownership
