Sec.  363.210  Is there any period of time during which I will be unable 
to process certain transactions regarding my security?

    A closed book period will be in effect for four business days prior 
to the date a marketable security interest or redemption payment is 
made. This means that certain transactions made during the closed book 
period will be delayed until after the closed book period is completed 
and the payment is made. You will be unable to transfer the security, 
change the payment destination, change the registration of the security, 
or use Treasury's Sell Direct[supreg] service during this closed book 
period.
