Our capital accounts are comprised of 2% general partner interests and 98% limited partner interests. The common units represent limited partner interests in us. The holders of common units, both public and SPLC, are entitled to participate in partnership distributions and have limited rights of ownership as provided for under our partnership agreement. Our general partner participates in our distributions and also currently holds IDR’s that entitle it to receive increasing percentages of the cash we distribute from operating surplus.

We have a universal shelf registration statement on Form S-3 on file with the SEC under which we, as a well-known seasoned issuer, have the ability to issue and sell an indeterminate amount of common units and partnership securities representing limited partner units. We also have on file with the SEC a shelf registration statement on Form S-3 relating to $1,000,000,000 of common units and partnership securities representing limited partner units to be used in connection with the at-the-market equity distribution program, direct sales, or other sales consistent with the plan of distribution set forth in the registration statement.

On February 6, 2018, we completed the sale of 25,000,000 common units in a registered public offering for $673 million net proceeds ($680 million gross proceeds, or $27.20 per common unit, less $6 million of underwriter’s fees and $1 million of transaction fees). In connection with the issuance of common units, we issued 510,204 general partner units to our general partner for $14 million in order to maintain its 2% general partner interest in us. On February 6, 2018, we also completed the sale of 11,029,412 common units in a private placement with Shell Midstream LP Holdings LLC for an aggregate purchase

price of $300 million, or $27.20 per common unit. In connection with the issuance of the common units, we issued 225,091 general partner units to the general partner for $6 million in order to maintain its 2% general partner interest in us. We used net proceeds from these sales to repay $247 million of borrowings outstanding under the Five Year Revolver due July 2023 and $726 million of borrowings outstanding under the Five Year Revolver due December 2022, as well as for general partnership purposes.

On March 2, 2016, we commenced an “at-the-market” equity distribution program pursuant to which we may issue and sell common units for up to $300 million in gross proceeds.

As of June 30, 2019, we had 233,289,537 common units outstanding, of which 123,832,233 were publicly owned. SPLC owned 109,457,304 common units, representing an aggregate 46.0% limited partner interest in us, all of the IDR’s, and 4,761,012 general partner units, representing a 2% general partner interest in us.
