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 June 30, 2014:
Hedged Transaction | Number and Type of Derivatives Outstanding |  | Notional Amount |  | Period of Hedge | Rate Swap | Accounting Treatment
Senior Notes AA | 10 fixed-to-floating swaps |  | $ | 750.0 |  | 1/2011 to 2/2016 | 3.2% to 1.2% | Fair value hedge
Undesignated swaps | 6 floating-to-fixed swaps |  | $ | 600.0 |  | 5/2010 to 7/2014 | 0.2% to 2.0% | Mark-to-market
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 June 30, 2014 (volume measures as noted):
| Volume (1) | Accounting
Derivative Purpose | Current (2) | Long-Term (2) | Treatment
Derivatives designated as hedging instruments: |  |  |
Natural gas processing: |  |  |
Forecasted natural gas purchases for plant thermal reduction (Bcf) | 2.2 | n/a | Cash flow hedge
Forecasted sales of NGLs (MMBbls) (3) | 0.6 | n/a | Cash flow hedge
Octane enhancement: |  |  |
Forecasted purchases of NGLs (MMBbls) | 0.1 | n/a | Cash flow hedge
Forecasted sales of octane enhancement products (MMBbls) | 1.6 | n/a | Cash flow hedge
Natural gas marketing: |  |  |
Natural gas storage inventory management activities (Bcf) | 3.3 | n/a | Fair value hedge
NGL marketing: |  |  |
Forecasted purchases of NGLs and related hydrocarbon products (MMBbls) | 6.2 | n/a | Cash flow hedge
Forecasted sales of NGLs and related hydrocarbon products (MMBbls) | 7.6 | n/a | Cash flow hedge
Refined products marketing: |  |  |
Forecasted purchases of refined products (MMBbls) | 0.6 | n/a | Cash flow hedge
Forecasted sales of refined products (MMBbls) | 1.0 | n/a | Cash flow hedge
Refined products inventory management activities (MMBbls) | 0.2 | n/a | Fair value hedge
Crude oil marketing: |  |  |
Forecasted purchases of crude oil (MMBbls) | 3.3 | n/a | Cash flow hedge
Forecasted sales of crude oil (MMBbls) | 5.0 | n/a | Cash flow hedge
Derivatives not designated as hedging instruments: |  |  |
Natural gas risk management activities (Bcf) (4,5) | 73.1 | 12.6 | Mark-to-market
Crude oil risk management activities (MMBbls) (5) | 13.2 | n/a | Mark-to-market
(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 March 2015, August 2014 and October 2016, respectively. (3) Forecasted sales of NGL volumes under natural gas processing exclude 0.6 MMBbls of additional hedges executed under contracts that have been designated as normal sales agreements. (4) Current volumes include 37.7 Bcf 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.
