Item 7.01.  Regulation FD Disclosure
On June 13, 2005, Plains All American Pipeline, L.P. (the “Partnership”) furnished a Current Report on Form 8-K, pursuant to Item 7.01, updating its second quarter 2005 guidance and establishing initial quarterly guidance for the third and fourth quarters of 2005.  Consistent with the Partnership’s actual distribution policies and procedures, the earnings per unit calculations included in that report were based on the estimated distributions to be made in those periods. As disclosed in our Annual Report on Form 10-K for the year ended December 31, 2004, in March 2004, but effective for the second quarter of 2004, the Financial Accounting Standards Board (“FASB”) ratified the consensus reached in the Emerging Issues Task Force (“EITF”) Issue 03-06: Participating Securities and the Two-Class Method under FASB Statement No. 128.  Essentially, EITF 03-06 provides that in any accounting period where our aggregate net income exceeds our aggregate distribution for such period, we are required to present earnings per unit as if all of the earnings for the period were distributed, regardless of the pro forma nature of this allocation and whether those earnings would actually be distributed during a particular period from an economic or practical perspective.  The theoretical results are then used to report our earnings per limited partner unit in accordance with generally accepted accounting principles.  EITF 03-06 will not impact overall net income or other financial results of the Partnership, however, for periods in which aggregate net income exceeds our aggregate distributions for such period, it will have the impact of reducing the earnings per limited partner unit. This result occurs as a larger portion of our aggregate earnings, as if distributed, is allocated to the incentive distribution rights held by our general partner, even though we make cash distributions on the basis of cash available for distributions, not earnings, in any given accounting period.   In accounting periods where aggregate net income does not exceed our aggregate distributions for such period, EITF 03-06 will not have any impact.
Accordingly, the table below indicates the items previously furnished that have been revised to reflect the impact of EITF 03-06 on those periods where our projected aggregate net income exceeds our projected aggregate distributions (items in table are in millions, except per unit data):

The forecast presented above does not include assumptions or projections with respect to potential gains or losses related to the derivative instruments accounted for under Statement of Financial Accounting Standards No. 133 “Accounting for Derivative Instruments and Hedging Activities” (SFAS 133).   The potential gains or losses related to these derivatives (primarily non-cash, mark-to-market adjustments) could cause actual net income to differ materially from our projections.
