 is converted into a fixed rate that reflects the yield that is reasonably expected for the Variable Interest Rate Debt Security. In the case of a Variable Interest Rate Debt Security that qualifies as a “variable rate debt instrument” and provides for stated interest at a fixed rate (other than an initial fixed rate described above) in addition to either one or more qualified floating rates or a qualified inverse floating rate, the fixed rate is initially converted into a qualified floating rate (or a qualified inverse floating rate, if the Variable Interest Rate Debt Security provides for a qualified inverse floating rate). Under these circumstances, the qualified floating rate or qualified inverse floating rate that replaces the fixed rate must be such that the fair market value of the Variable Interest Rate Debt Security as of the Variable Interest Rate Debt Security’s issue date is approximately the same as the fair market value of an otherwise identical debt instrument that provides for either the qualified floating rate or qualified inverse floating rate rather than the fixed rate. Subsequent to converting the fixed rate into either a qualified floating rate or a qualified inverse floating rate, the Variable Interest Rate Debt Security is converted into an “equivalent” fixed rate debt instrument in the manner described above.

Once the Variable Interest Rate Debt Security is converted into an “equivalent” fixed rate debt instrument pursuant to the foregoing rules, the amount of OID and qualified stated interest, if any, are determined for the “equivalent” fixed rate debt instrument by applying the general OID rules to the “equivalent” fixed rate debt instrument and a U.S. Holder of the Variable Interest Rate Debt Security will account for the OID and qualified stated interest as if the U.S. Holder held the “equivalent” fixed rate debt instrument. In each accrual period, appropriate adjustments will be made to the amount of qualified stated interest or OID assumed to have been accrued or paid with respect to the “equivalent” fixed rate debt instrument in the event that these amounts differ from the actual amount of interest accrued or paid on the Variable Interest Rate Debt Security during the accrual period.

If a Variable Interest Rate Debt Security does not qualify as a “variable rate debt instrument”, then the Variable Interest Rate Debt Security will generally be treated as a contingent payment debt obligation. The proper U.S. federal income tax treatment of Variable Interest Rate Debt Securities that are treated as contingent payment debt obligations will be more fully described in the applicable prospectus supplement.
