Item 8.01.    Other Events.

The terms “we”, “us”, “our” and similar language included in this Current Report on Form 8-K refers to Magellan Midstream Partners, L.P., together with its subsidiaries. During first quarter 2020, we completed a reorganization of our reporting segments. This reorganization was effected to reflect changes in the management of our business in conjunction with the sale of three of our marine terminals. 

Accordingly, effective March 1, 2020, we redesigned our internal management reports to correspond to this new organizational structure, resulting in changes to our reporting segments. Our new reporting segments are as follows:

• Refined products; and

• Crude oil.

A summary of each of our current reporting segments follows:

• Our refined products segment is comprised of our approximately 9,800-mile refined products pipeline system with 53 connected terminals, as well as 25 independent terminals not connected to our pipeline system and five marine terminals (one of which is owned through a joint venture).

• Our crude oil segment is comprised of approximately 2,200 miles of crude oil pipelines, a condensate splitter and 37 million barrels of aggregate storage capacity, of which approximately 25 million barrels are used for contract storage. Approximately 1,000 miles of these pipelines, the condensate splitter and 30 million barrels of this storage capacity (including 22 million barrels used for contract storage) are wholly-owned, with the remainder owned through joint ventures.

Exhibit 99.1 hereto updates the following information contained in our Annual Report on Form 10-K for the year ended December 31, 2019 filed with the Securities and Exchange Commission on February 18, 2020 ("2019 10-K") to reflect these changes in reportable segments: (i) Item 1. Business; (ii) Item 6. Selected Financial Data; (iii) Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations ("MD&A"); and (iv) Item 8. Financial Statements and Supplementary Data.
