	2016		2016		2016			2016

Carrying value adjustment		148		122
Total debt	$	94,086	$	93,594		1.43	%		1.30	%

Included in the carrying value of our debt are unamortized premiums, discounts and debt issuance costs of $297 million and $280 million as of September 30, 2016 and March 31, 2016, respectively. The face value of commercial paper, unsecured notes and loans payable and secured notes and loans payable was $27.8 billion, $52.3 billion, and $14.2 billion, respectively, as of September 30, 2016, and $26.6 billion, $53.0 billion and $14.1 billion, respectively, as of March 31, 2016.

As of September 30, 2016, our commercial paper had a weighted average remaining maturity of 95 days, while our unsecured and secured 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.

Our unsecured notes and loans payable consist of both fixed and variable rate debt with contractual interest rates ranging from 0 percent to 9.4 percent at September 30, 2016 and March 31, 2016. 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 unsecured notes and loans payable contain covenants and conditions customary in transactions of this nature, including negative pledge provisions, cross-default provisions and limitations on certain consolidations, mergers and sales of assets. We are currently in compliance with these covenants and conditions.

Certain unsecured notes and loans payable are denominated in various foreign currencies, and include the impact of translation adjustments. At September 30, 2016 and March 31, 2016, the carrying values of these foreign currency denominated notes and loans payable were $13.5 billion and $13.1 billion, respectively. Concurrent with the issuance of these foreign currency unsecured notes and loans payable, we entered into foreign currency swaps in the same notional amount to convert non-U.S. currency payments to U.S. dollar denominated payments.

Our secured notes and loans payable are denominated in U.S. dollars and consist of both fixed and variable rate debt with contractual interest rates ranging from 0.7 percent to 1.7 percent at September 30, 2016 and 0.5 percent to 1.7 percent at March 31, 2016. Secured notes and loans payable are issued using on-balance sheet securitization trusts, as further discussed in Note 10 – Variable Interest Entities. These notes are repayable only from collections on the underlying securitized retail finance receivables and the beneficial interests in investments in operating leases and from related credit enhancements.

The carrying value adjustment on debt represents the effects of fair value adjustments to debt in hedging relationships, accrued redemption premiums, and the unamortized fair value adjustments on the hedged item for terminated fair value hedge accounting relationships. The carrying value adjustment on debt increased by $26 million at September 30, 2016 compared to March 31, 2016 primarily as a result of changes in U.S. dollar rates relative to certain other currencies in which our hedged debt is denominated.
