Things you should know about your MPNs :

Your MPNs may have been used as a multi-year note if:
your school was authorized for multi-year use or
you did not change lenders.
The multi-year feature of your MPNs is in effect for 10 years
from the date of your signature, so if you go back to school,
you may not be required to sign a new note. An MPN may
be revoked:
if you send a written notice to your lender,
if you declare bankruptcy, or
upon expiration of the 10-year period.
Your MPNs may have only been used for one year at a time
because:
your school was not authorized for or chose not to use the multi-
year function,
you chose to sign a new note, or
you changed lenders.
