8. Partners’ Capital and Distributions

Common Units

In September 2013, we issued 5,750,000 Class A common units in a public offering at a price of $47.51 per unit. We received proceeds, net of underwriting discounts and offering costs, of approximately $263.6 million from that offering. We used the net proceeds for general partnership purposes, including the repayment of outstanding borrowings under our revolving credit facility. At September 30, 2013, our outstanding common units consisted of 88,650,988 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 were/are convertible into Class A common units at a 1:1 conversion rate in the calendar quarter 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 was $0.49 for our Class 3 waiver units and is $0.52 for our Class 4 waiver units.

Our Class 1 and Class 2 waiver units converted into common units in 2012.

On May 15, 2013, our Class 3 waiver units became convertible as we paid a distribution of $0.4975 per common unit and satisfied the conversion coverage ratio requirement. All Class 3 waiver units were converted into common units by June 30, 2013.

At September 30, 2013, we had 1,738,233 waiver units outstanding comprised of the Class 4 waiver units. The Class 4 waiver units will covert into common units when we satisfy the conversion ratio requirement and pay a minimum distribution of $0.52 per common unit.
