Dear Sir/Madam:

I would like to draw a simple analogy to the CBOE proposed rule change vis a vis the exercise right privilige of CBOT Full members. I owe Sam Smith $100. Sam Smith changes his name to John Jones. I decree that since Sam Smith no longer exists, my contractural obligation is extinguished.
