Financial Instruments and Other Financing Arrangements

Financial Instruments

We utilize derivative financial instruments to manage exposure to certain risks related to our ongoing operations. The primary risks managed through the use of derivative instruments include interest rate risk, currency exchange risk and commodity price risk. We do not use derivative instruments for trading or speculative purposes. While the majority of our derivative instruments are designated as hedging instruments, we also enter into derivative instruments that are designed to hedge a risk, but are not designated as hedging instruments. These derivative instruments are adjusted to current fair value through earnings at the end of each period. Our derivative and hedging programs are consistent with those described in our 2013 Form 10-K.

During the six months ended December 31, 2013, we entered into pay-floating interest rate swaps with total notional amounts of $300 million. These swaps have been designated as fair value hedges of our fixed rate debt and are included in other assets in the condensed consolidated balance sheets at December 31, 2013.

Fair Value of Financial Instruments

The carrying amounts of cash and equivalents, trade receivables, net, accounts payable and other accrued liabilities at December 31, 2013 and June 30, 2013 approximate fair value due to their short-term maturities.

The following table summarizes the estimated fair value of our long-term obligations and other short-term borrowings compared to the respective carrying amounts at:



(in millions)	December 31, 2013		June 30, 2013
Estimated fair value	$	3,995	$	3,899
Carrying amount	3,934		3,854

The estimated fair value of our long-term obligations and other short-term borrowings is estimated based on either the quoted market prices for the same or similar issues or other inputs derived from available market information, which represents a Level 2 measurement. See Note 8 for further information regarding fair value measurements.

Other Financing Arrangements

On October 15, 2013, we reduced our committed receivables sales facility program from $950 million to $700 million in light of the expiration of our pharmaceutical distribution contract with Walgreens. Our committed receivables sales facility program is available to us through Cardinal Health Funding, LLC ("CHF"), which was organized for the sole purpose of buying receivables and selling undivided interests in those receivables to third-party purchasers. Although consolidated in accordance with GAAP, CHF is a separate legal entity from Cardinal Health and from our subsidiary that sells the receivables to CHF. CHF is designed to be a special purpose, bankruptcy-remote entity whose assets are available solely to satisfy the claims of its creditors.
