Sec.  363.131  What is a TreasuryDirect[supreg] certificate of 
indebtedness?

    A TreasuryDirect certificate of indebtedness (certificate of 
indebtedness) is a security held within your primary or linked account, 
including a minor account for which you are the custodian, that is 
issued daily, with a one-day maturity, that automatically rolls over at 
maturity until you request redemption. A certificate of indebtedness has 
a minimum purchase amount of one cent. The only purpose of a certificate 
of indebtedness is to accumulate funds for the purchase of another 
eligible security in the TreasuryDirect system. A certificate of 
indebtedness within a minor's account is the property of the minor 
alone.
