| (*) | Bondholders may not require prepayment in any case, and the Company has a call option to repay all of these bonds on or after 12 years from the date of issuance of the bonds, or on each interest payment date henceforth. In addition, there is a step-up clause from the date of the initial call option exercise. Although these instruments have contractual maturity dates, the contractual agreements allow these subsidiaries to indefinitely extend the maturity dates and defer the payment of interest without modification to the other terms of the instruments. When the Company decides not to pay dividends on common shares, they are not required to pay interest on the hybrid bonds.
