Partners' Capital Notes [Abstract] |
Partners' Capital And Distributions | 7. Partners’ Capital and Distributions At March 31, 2013, our outstanding common units consisted of 81,162,755 Class A units and 39,997 Class B units. Waiver Units Our waiver units are non-voting securities entitled to a minimal preferential quarterly distribution. At issuance our waiver units were comprised of four classes (designated Class 1, Class 2, Class 3 and Class 4) of 1,738,000 units each. The waiver units in each class are convertible into Class A common units in the calendar quarter at a 1:1 conversion rate during which each of our common units receives a specified minimum quarterly distribution and our distribution coverage ratio (after giving effect to the then convertible waiver units) would be at least 1.1 times. The minimum distribution per common unit required for conversion is $0.43 (Class 1), $0.46 (Class 2), $0.49 (Class 3) and $0.52 (Class 4). On February 14, 2012, our Class 1 waiver units became convertible as we paid a distribution of $0.44 per common unit and satisfied the conversion coverage ratio requirement. All Class 1 waiver units were converted into common units by March 31, 2012. On August 14, 2012, our Class 2 waiver units became convertible as we paid a distribution of $0.46 per common unit and satisfied the conversion coverage ratio requirement. All Class 2 waiver units were converted into common units by September 30, 2012. At March 31, 2013, we had 3,476,466 waiver units outstanding comprised of the Class 3 and Class 4 waiver units. On May 15, 2013, our Class 3 waiver units will become convertible (at the option of the holder therof) as we will pay a distribution of $0.4975 per common unit and satisfy the conversion coverage ratio requirement. Those waiver units will automatically convert into Class A common units on November 15, 2013. Distributions We paid or will pay the following distributions in 2012 and 2013:
