Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligation of the registrant under any of the following provisions (see General Instruction A.2. below):

On April 9, 2015, we entered into an agreement with Société Générale S.A. to transfer certain client exchange and over-the-counter transactions associated with our futures business for the net book value of the over-the-counter transactions, calculated in accordance with certain principles set forth in the agreement, plus the repayment of certain margin loans in respect of certain exchange transactions. In addition, we agreed to enter into a total return swap with respect to other over-the-counter transactions which will not be transferred, which is intended to replicate the economics of such non-transferred over-the-counter transactions. The transfer is subject to customary closing conditions for a transaction of this nature. We anticipate that the completion of this transaction will occur during the second quarter of 2015. We are not able to estimate, at this time, the total assets and liabilities that will be transferred as such amounts will fluctuate based on daily client activity through the date of closing.

In addition, we expect to terminate our $750.0 million credit facility shortly after the closing of the above transaction. Upon termination of the credit facility, unamortized deferred origination costs of $5.4 million will be expensed.

Concurrently, we initiated a plan to exit the remaining aspects of our existing futures business and to terminate the remaining client agreements with respect to exchange transactions. We estimate that we will incur the pre-tax costs set forth below that aggregate approximately $91.2 million in connection with this plan, primarily over the remainder of our 2015 fiscal year. We expect the effect of these costs to be approximately $65.8 million on an after-tax basis. Of the total estimated costs, approximately $23.0 million are of a non-cash nature and approximately $68.2 million will result in future cash expenditures.

All of the above costs associated with our plan to exit our futures business, the nature of such costs and the effect of such costs are estimates only and are subject to change. These estimates, as well as other statements contained herein constitute “forward looking statements” within the meaning of the safe harbor provisions of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. Forward looking statements include statements about our future and statements that are not historical facts and represent only our belief regarding future events, many of which by their nature are inherently uncertain. It is possible that the actual results may differ, possibly materially, from the anticipated results indicated in these forward looking statements.
