Item 8.01 Other Events

As previously announced by Penson Worldwide, Inc. (the "Company"), Penson Financial Services, Inc. ("PFSI"), a subsidiary of the Company, recently completed certain strategic transactions with Knight Execution & Clearing Services LLC and Apex Clearing Corporation that resulted in a significant refocus of the Company's business, including, among other things, the cessation of PFSI as a clearing broker-dealer in the United States. Accordingly, on August 3, 2012, PFSI filed a Form BDW (Uniform Request for Broker-Dealer Withdrawal) with the Securities and Exchange Commission (the "SEC") and Financial Industry Regulatory Authority ("FINRA") to voluntarily withdraw its registration with the SEC as a broker-dealer and to resign as a member of the FINRA. Such withdrawal request is subject to the approval and acceptance of the SEC and FINRA, which are pending.
