Our Series A Preferred Units rank senior to our common units and Class B Units as to the payment of distributions and amounts payable upon liquidation, dissolution or winding up. Our Series A Preferred Units have a liquidation preference of $24.00 per unit, plus any Series A Unpaid Cash Distributions, plus all accrued but unpaid distributions on such Series A Preferred Unit with respect to the quarter in which the liquidation occurs to the date fixed for the payment of any amount upon liquidation. Our Series A Preferred Units are entitled to cumulative distributions from their initial issuance date, with distributions being calculated at an annual rate of 8.0% on the stated liquidation preference and payable quarterly in arrears within 45 days after the end of each quarter, when, as and if declared by our board of directors.
The Series A Preferred Units are generally convertible, at the option of the holders of the Series A Preferred Units, into common units at the applicable conversion rate. The conversion rate will be subject to adjustment under certain circumstances. In addition, the conversion rate will be redetermined on a quarterly basis, such that the conversion rate will be equal to $24.00 (the “Issue Price”) divided by the product of (x) the book value per common unit at the end of the immediately preceding quarter (pro-forma for per unit cash distributions payable with respect to such quarter) multiplied by (y) the quotient of (i) the Issue Price divided by (ii) the book value per common unit on February 2, 2017. In addition, the Partnership may redeem the Series A Preferred Units at any time until February 2, 2027 at the redemption price specified in our partnership agreement, provided, however, that upon notice from us to the holders of Series A Preferred Units of our intent to redeem, such holders may elect, instead, to convert their Series A Preferred Units into common units at the applicable conversion rate.
Upon a change of control of the Partnership, the holders of Series A Preferred Units will have the right to require cash redemption at 100% of the Issue Price. In addition, the holders of Series A Preferred Units will have the right to cause the Partnership to redeem the Series A Preferred Units on February 2, 2027 in, at the option of the Partnership, (i) cash at a price equal to 70% of the Issue Price or (ii) common units such that each Series A Preferred Unit receives common units worth 80% of the Issue Price (based on the volume-weighted average trading price, as adjusted for splits, combinations and other similar transactions, of our common units as reported on the NYSE for the 30 trading day period ending on the fifth trading day immediately prior to the redemption date) plus any accrued and unpaid distributions. In addition, subject to certain conditions, we have the right to convert the Series A Preferred Units into common units at the applicable conversion rate if the aggregate market value (calculated as set forth in the partnership agreement) of the common units into which the outstanding Series A Preferred Units are convertible, based on the applicable conversion rate, is greater than 130% of the aggregate Issue Price of the outstanding Series A Preferred Units.
