Summary of WILLIAMS PARTNERS L.P.

Item 8.01. Other Events
In January 2009, Williams Partners L.P. adopted Emerging Issues Task Force (EITF) Issue No. 07-4, "Application of the two-class method under FASB Statement No. 128, Earnings per Share, to Master Limited Partnerships." EITF Issue No. 07-4 states, among other things, that the calculation of earnings per unit should not reflect an allocation of undistributed earnings to the incentive distribution right (IDR) holders beyond amounts distributable to IDR holders under the terms of its partnership agreement. Previously, under generally accepted accounting principles, we calculated earnings per unit as if all the earnings for the period had been distributed, which resulted in an additional allocation of income to the general partner (the IDR holder) in quarterly periods where an assumed incentive distribution exceeded the actual incentive distribution. Following the adoption of this guidance, we no longer calculate assumed incentive distributions. We have retrospectively applied this guidance to all periods presented. The retrospective application of this guidance decreased the income allocated to the general partner and increased the income allocated to limited partners for the amount that any assumed incentive distribution exceeded the actual incentive distribution calculated during that period. Certain of our historical periods' earnings per unit have been revised as a result of this change. Adoption of this new guidance only impacts the allocation of earnings for purposes of calculating our earnings per limited partner unit and has no impact on our results of operations, allocation of earnings to capital accounts, or distributions of available cash to unitholders and our general partner.
In January 2009, Williams Partners GP LLC (the "General Partner"), our general partner, adopted Statement of Financial Accounting Standards (SFAS) No. 160, "Noncontrolling Interests in Consolidated Financial Statements - an amendment of Accounting Research Bulletin No. 51." Our General Partner has revised certain historical financial information previously included in Exhibit 99.1 of our Annual Report on Form 10-K for the fiscal year ended December 31, 2008, to reflect the retrospective presentation and disclosure requirements of this new guidance. Noncontrolling interests in consolidated subsidiaries (previously referred to as minority interests) are now presented in the consolidated balance sheet as a separate component of equity.
The following items of our Form 10-K for the fiscal year ended December 31, 2008, have been revised for the items described above, to the extent applicable, and are filed as exhibits to this Current Report on Form 8-K as indicated below and are incorporated herein by reference:
