After 1935, the German Reich issued two main interest bearing debt securities: Loans of the German Reich in the form of Bonds and callable treasury bills.
The difference between these two securities lay mainly in the repayment conditions. The bond had a maximum maturity of 10 years. Every year 10 Percent was repaid. Additional to the nominal, half-yearly interest, they had an additional interest payment: If the Reich made a profit in the repayment of the bond, i.e. the difference between the nominal value of 100% and the repayment value, then this profit was distributed to the remaining bonds holders.
The callable treasury bills had a 10-year maturity and an identical nominal interest. There was, however, no repayment during the first five years. Every year in its last five years, two numbers between 0 and 9 were drawn and all the Treasury bill whose last digit corresponded to the number drawn from the lot were repaid.
