Derivative Instruments, Hedging Activities and Fair Value Measurements [Abstract]  
Hedging Instruments Under the FASB's Derivative and Hedging Guidance
We may utilize interest rate swaps, forward starting swaps and similar derivative instruments to manage our exposure to changes in interest rates charged on borrowings under certain consolidated debt agreements.  The following table summarizes our portfolio of interest rate swaps at September 30, 2014:

Fair value hedge

The prices of natural gas, NGLs, crude oil, refined products and petrochemical products are subject to fluctuations in response to changes in supply and demand, market conditions and a variety of additional factors that are beyond our control.  In order to manage such price risks, we enter into commodity derivative instruments such as physical forward contracts, futures contracts, fixed-for-float swaps, basis swaps and option contracts.  The following table summarizes our portfolio of commodity derivative instruments outstanding at September 30, 2014 (volume measures as noted):

(1)      Volume for derivatives designated as hedging instruments reflects the total amount of volumes hedged whereas volume for derivatives not designated as hedging instruments reflects the absolute value of derivative notional volumes.
(2)      The maximum term for derivatives designated as cash flow hedges, derivatives designated as fair value hedges and derivatives not designated as hedging instruments is December 2015, October 2015 and March 2018, respectively.
(3)      Forecasted sales of NGL volumes under natural gas processing exclude 0.3 MMBbls of additional hedges executed under contracts that have been designated as normal sales agreements.
(4)      Current and long-term volumes include 28.9 Bcf and 0.9 Bcf, respectively, of physical derivative instruments that are predominantly priced at a marked-based index plus a premium or minus a discount related to location differences.
(5)       Reflects the use of derivative instruments to manage risks associated with transportation, processing and storage assets.

During the nine months ended September 30, 2013, we recorded $53.3 million of non-cash asset impairment charges.  These charges primarily represent the abandonment of crude oil and natural gas pipeline segments in Texas, Oklahoma and the Gulf of Mexico, certain refined products terminal assets in Texas, and an NGL storage cavern in Arizona.  The following table summarizes our non-recurring fair value measurements for the nine months ended September 30, 2013:
