Partners' Capital And Distributions [Abstract] |
Partners' Capital And Distributions | 9. Partners' Capital and Distributions On March 28, 2012, we issued 5,750,000 Class A common units in a public offering at a price of $30.80 per unit. We received proceeds, net of underwriting discounts and offering costs, of $169.5 million from the offering. The net proceeds were used for general corporate purposes, including the repayment of borrowings under our credit facility. At March 31, 2012, our outstanding common units consisted of 79,424,522 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 1,750,000 authorized units each, of which 1,738,000 units of each class have been issued. 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. At March 31, 2012, we had 5,214,099 waiver units outstanding comprised of the last three classes. Distributions We paid or will pay the following distributions in 2011 and 2012:
