Unless otherwise specified in the applicable prospectus supplement, the debt securities will not be listed on any securities exchange. We may offer and sell our debt securities at a substantial discount below their stated principal amount. These debt securities may be original issue discount securities, which means that less than the entire principal amount of the original issue discount securities will be payable upon declaration of acceleration of their maturity. Special federal income tax, accounting and other considerations applicable to original issue discount securities will be described in the applicable prospectus supplement. We may issue debt securities with a fixed interest rate or a floating interest rate.
