Derivative Instruments, Hedging Activities and Fair Value Measurements [Abstract] |
Hedging Instruments Under the FASB's Derivative and Hedging Guidance | The following table summarizes our portfolio of interest rate swaps at December 31, 2013:
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 December 31, 2013 (volume measures as noted):

(1) | The increase in other comprehensive loss in 2011 and 2012 was primarily due to the impact of decreases in forward London Interbank Offered Rates ("LIBOR") on our forward starting interest rate swap portfolio.
(2) | The increase in other comprehensive loss in 2011 was primarily due to the impact of rising commodity prices on our cash flow hedges associated with physical future deliveries of NGLs, crude oil and refined products.
(3) | The fair value of these derivative instruments would be reclassified to their respective locations on the Statement of Consolidated Operations upon settlement of the underlying derivative transactions, as appropriate.
