Employee Questions & Answers

as of December 15, 2006

 

    What does the “second request” that the CBOT received from the Department of Justice (DOJ) mean and how does it impact the merger with the CME?

The Department of Justice Antitrust Division must approve the merger in order to close the transaction. We have received what is called a second request from the DOJ for more information regarding our businesses, which was expected. We are fully engaged in working with the DOJ as part of this process and continue to expect the deal to close in mid-2007.

 

    Will the new company have the same tuition reimbursement program as the CBOT?

This has not yet been determined but will likely be addressed either as the transaction draws nearer to close or following the deal’s completion.

However, there are no plans to change how the tuition reimbursement program is handled while the CBOT is a separate entity from CME. For example, as always, you must obtain prior approval from your manager before enrolling in a course, the course must be job-related, you must attend an accredited institution and you must meet certain grade requirements.

If your position is no longer required after the merger is finalized, you will not be required to reimburse the CBOT for any courses for which you previously received reimbursement, or for any courses in which you were enrolled and for which you had already received approval.

 

    If I were to leave the Exchange voluntarily prior to the closing of the merger, how would this impact my tuition reimbursement?

Under CBOT’s current tuition reimbursement program, if you are a full-time employee and you resign from the CBOT, you will be required to repay any tuition reimbursement you received in the preceding year prior to your separation.


Part-time employees must continue to be employed by the CBOT for two full years upon completion of their most recent class. Part-time employees who choose to leave the CBOT before two years have expired after receipt of a tuition reimbursement will be required to repay the amount they have been reimbursed by the CBOT in such two year period prior to termination.

 

    If I receive an offer of a position in the new company, will I be required to undergo a three-month probation period and interview? What will be the process?

The process of planning the integration of the two companies is being considered by the Transition Planning Team, which consists of management from both CME and CBOT. Staffing decisions for the combined company will be made by management of the new organization.

 

    If my dependent and I are enrolled in the Supplemental or Dependent Life Insurance Policy, will my dependent and I lose our policies if my employment is terminated in connection with the merger?

All of your CBOT life insurance policies, including any CBOT Supplemental and Dependent Life Insurance Policies, would end on your termination date; however, you would have the opportunity to convert your life insurance (basic, supplemental, and dependent) into individual policies at your own expense within 30 days of your separation from the CBOT. The cost of individual policies varies based on your or your dependents’ age and amount of coverage.

The benefits package for the combined company has not yet been determined.

 

    If my position is eliminated as a result of the pending merger, what will happen to my accrued PTO days that I carry over from 2006 to 2007? Additionally, will I be paid for the 2007 PTO time that I do not take if my position is eliminated?

Under the CBOT’s current PTO policy, you may carry over up to three earned but not used PTO days from 2006 to 2007. If you do not use those carried-over days in 2007, and if your employment terminates in 2007, you will be paid your earned but not used PTO. This payout would include any additional earned, unused 2007 PTO time.
