The comparisons generated by the Calculator have been developed by OneChicago for assessment and evaluation purposes only. All quotes used in calculations are simultaneous, delayed quotes from the prior trading day, where possible. They are not the current bid and offer prices, which can only be obtained through a OneChicago member. Therefore, the quotes should not be relied upon for execution purposes.

OneChicago wishes to express its appreciation to Dr. Robert Mackay, Senior Vice-President, and Dr. Sharon Brown-Hruska, Vice-President, of the international firm of NERA Economic Consulting for their invaluable guidance and help in the design and testing of the calculator.
