Financial Instruments Measured and Recognized at Fair Value

We estimate fair value at a price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants in the principal market for the asset or liability. Other than the derivative instruments discussed in “Note 9 – Derivative Instruments,” we had no other material assets or liabilities measured and recognized at fair value on a recurring basis at March 31, 2015 and December 31, 2014.

Fair Value of Other Financial Instruments

Our other financial instruments include short-term borrowings and long-term debt. The carrying value of our commercial paper and other short-term borrowings approximates their fair value due to the short-term duration of the associated interest rate periods. These short-term borrowings are classified as Level 2 in the fair value hierarchy.

The fair value of our long-term debt fluctuates with changes in applicable interest rates among other factors. Fair value will exceed carrying value when the current market interest rate is lower than the interest rate at which the debt was originally issued. The fair value of our long-term debt is classified as Level 2 in the fair value hierarchy and is a measure of its current value under present market conditions and is established based on observable inputs in less active markets.

The fair value and carrying value of our senior notes were as follows:



(Dollars in millions)	March 31, 2015		December 31, 2014
Fair value	$	6,592	$	6,733
Carrying value	6,498		6,660
