Item 8.01 |  | Other Events.

Effective July 1, 2016, Tesoro Logistics LP (the "Partnership" or "TLLP") entered into a transaction (the “Alaska Storage and Terminalling Assets Acquisition”) with Tesoro Corporation ("Tesoro") to purchase certain terminalling and storage assets owned by Tesoro. On July 1, 2016, the Partnership completed the acquisition of the first phase consisting of tankage with a shell capacity of approximately 3.5 million barrels and ancillary facilities used for the operations at Tesoro’s Kenai Refinery. The second phase was completed on September 16, 2016 and consisted of refined product terminals in Anchorage and Fairbanks (together, the “Alaska Storage and Terminalling Assets”).
This transaction was a transfer between entities under common control. Accordingly, the Partnership's combined consolidated financial statements and notes have been retrospectively adjusted to include the financial results of the Alaska Storage and Terminalling Assets for all periods presented.
Included herein as Exhibit 99.3 are the audited combined consolidated financial statements of the Partnership as of December 31, 2015 and 2014 and for the years ended December 31, 2015, 2014 and 2013. These audited combined consolidated financial statements give retrospective effect to the Alaska Storage and Terminalling Assets Acquisition. These audited combined consolidated financial statements update Item 8 in the Partnership’s 2015 Form 10-K filed with the SEC on February 25, 2016 (the "2015 Form 10-K"). Also, included herein as Exhibit 99.1 is the Selected Financial Data, which are derived from the audited combined consolidated financial statements, and updates Item 6 in the Partnership’s 2015 Form 10-K. Included herein as Exhibit 99.2 is Management’s Discussion and Analysis of Financial Condition and Results of Operations, which relates to the audited combined consolidated financial statements, and updates Item 7 in the Partnership’s 2015 Form 10-K. Certain changes with respect to our use of non-GAAP measures have been made to conform to the presentation and disclosure of non-GAAP measures as reported in the Partnership's quarterly report on Form 10-Q for the periods ended June 30, 2016.
