The commercial paper balance includes unamortized premiums and discounts. Included in unsecured notes and loans payable are notes and loans denominated in various foreign currencies, unamortized premiums and discounts and the effects of foreign currency transaction gains and losses on non-hedged or de-designated foreign currency denominated notes and loans payable. At June 30, 2013 and March 31, 2013, the carrying values of these foreign currency denominated notes payable were $12.3 billion and $13.2 billion, respectively. Concurrent with the issuance of these foreign currency unsecured notes, we entered into currency swaps in the same notional amount to convert non-U.S. currency payments to U.S. dollar denominated payments.

Additionally, the carrying value of our unsecured notes and loans payable at June 30, 2013 included $16.9 billion of unsecured floating rate debt with contractual interest rates ranging from 0 to 6.0 percent and $30.2 billion of unsecured fixed rate debt with contractual interest rates ranging from 0.5 to 9.4 percent. The carrying value of our unsecured notes and loans payable at March 31, 2013 included $16.8 billion of unsecured floating rate debt with contractual interest rates ranging from 0 to 6.0 percent and $30.4 billion of unsecured fixed rate debt with contractual interest rates ranging from 0.5 percent to 9.4 percent. Upon issuance of fixed rate notes, we generally elect to enter into interest rate swaps to convert fixed rate payments on notes to floating rate payments.

Our secured notes and loans payable are denominated in U.S. dollars and consist of both fixed and variable rate debt with interest rates ranging from 0.4 percent to 1.9 percent at both June 30, 2013 and March 31, 2013. Secured notes and loans are issued by on-balance sheet securitization trusts, as further discussed in Note 10 – Variable Interest Entities. These notes are repayable only from collections on the underlying pledged retail finance receivables and the beneficial interests in investments in operating leases and from related credit enhancements.

As of June 30, 2013, our commercial paper had a weighted average remaining maturity of 88 days, while our notes and loans payable mature on various dates through fiscal 2047. Weighted average contractual interest rates are calculated based on original notional or par value before consideration of premium or discount.
