Item 8.01 Other Events.

Effective April 1, 2012, we entered into a transaction ("the Contribution") with Tesoro Corporation ("Tesoro"), Tesoro Refining and Marketing Company ("TRMC"), Tesoro Logistics GP, LLC ("TLGP") and our subsidiary, Tesoro Logistics Operations, LLC (the "Operating Company"), pursuant to which TRMC contributed, through TLGP and Tesoro Logistics LP ("TLLP" or the "Partnership"), to the Operating Company the Martinez Crude Oil Marine Terminal (the "Martinez Terminal"). The transfer of assets between Tesoro and TRMC, and TLGP and TLLP, represents a transfer of assets between entities under common control. Transfers of net assets or exchanges of shares between entities under common control are accounted for as if the transfer occurred at the beginning of the period, and prior years are retrospectively adjusted to furnish comparative information. As a result, TLLP is providing combined consolidated financial statements to include the financial results of the Martinez Terminal for all periods presented.

Included herein as Exhibit 99.1 are the unaudited combined consolidated financial statements of the Partnership as of March 31, 2012 and December 31, 2011 and for the three months ended March 31, 2012 and 2011. These unaudited combined consolidated financial statements give retrospective effect to the Contribution of the Martinez Terminal. These unaudited combined consolidated financial statements update Item 1 in the Partnership’s Quarterly Report on Form 10-Q for the first quarter of 2012 filed with the SEC on May 8, 2012 (the "Form 10-Q"). Included herein as Exhibit 99.2 is Management’s Discussion and Analysis of Financial Condition and Results of Operations, which relates to the unaudited combined consolidated financial statements, and updates Item 2 in the Partnership’s Form 10-Q.
