Class of Warrant or Right [Line Items]
Rights Agreement, Description	On July 19, 2006, we entered into a rights agreement with Computershare Investor Services, LLC, as amended effective February 28, 2008 and October 23, 2012 (the Rights Agreement), under which one preferred unit purchase right (a Right) is attached to each of our outstanding units. The Rights become exercisable under specified circumstances, including if any person or group (an acquiring person) becomes the beneficial owner of 15% or more of our outstanding units, subject to specified exceptions. Each Right entitles the registered holder to purchase from us one one-hundredth of a unit of junior participating preferred units, series I (Preferred Units) at an exercise price of $100, subject to adjustment under specified circumstances. If events specified in the Rights Agreement occur, each holder of Rights other than the acquiring person can exercise their Rights. When a holder exercises a Right, the holder will be entitled to receive units valued at a multiple of the exercise price of the Right specified in the Rights Agreement. In some cases, the holder will receive cash, property or other securities instead of units. We may redeem the Rights for $0.001 per Right at any time prior to the tenth day after a person or group becomes an acquiring person. The Rights will expire on June 30, 2016, unless extended or earlier redeemed or exchanged, and are protected by customary anti-dilution provisions. Preferred Units purchasable upon exercise of the Rights will not be redeemable. Each Preferred Unit will be entitled to share in our distributions of available cash pro rata with the units. In the event of liquidation, the holders of the Preferred Units will be entitled to a minimum preferential liquidation payment of $100 per unit. Each Preferred Unit will have 100 votes, voting together with the units. Finally, in the event of any merger, consolidation or other transaction in which units are exchanged, each Preferred Unit will be entitled to receive 100 times the amount received per unit.
