F. Customer understands that OCC assigns exercises to clearing firms such as IB and Customer acknowledges that it has read and understands the description of the OCC assignment procedures set forth in Chapter XI of the OCC Document. Customer acknowledges that, upon assignment, Customer shall be required: (1) in the case of an equity option, to deliver or accept the required number of shares of the underlying security, or (2) in the case of an equity index option, to pay or receive the settlement price, in cash.
