| | On April 26, 2007, the Audit Committee of the Board of Directors of our general partner, ONEOK Partners GP, L.L.C., recommended and approved the dismissal of KPMG LLP as principal accountants effective with the filing of our Form 10-Q for the period ended March 31, 2007. On May 2, 2007 that firm was dismissed. The audit reports of KPMG LLP on the consolidated financial statements of ONEOK Partners, L.P. ( formerly Northern Border Partners, L.P.) and subsidiaries as of and for the years ended December 31, 2006 and 2005 did not contain any adverse opinion or disclaimer of opinion, nor were they qualified or modified as to uncertainty, audit scope, or accounting principles. The audit reports of KPMG LLP on management's assessment of the effectiveness of internal control over financial reporting and the effectiveness of internal control over financial reporting as of December 31, 2006 and 2005 did not contain any adverse opinion or disclaimer of opinion, nor were they qualified or modified as to uncertainty, audit scope, or accounting principles. During the two fiscal years ended December 31, 2006, and the subsequent interim period through May 2, 2007, there were (a) no disagreements, as described under Item 304(a)(1)(iv) of Regulation S-K, with KPMG LLP on any matter of accounting principles or practices, financial statement disclosure, or auditing scope and procedures, which disagreements, if not resolved to the satisfaction of KPMG LLP, would have caused KPMG LLP to make reference to the matter in their report on or review of the financial statements for such periods, and (b) no reportable events, as described under Item 304(a)(1)(v) of Regulation S-K. On April 26, 2007, the Audit Committee of the Board of Directors of our general partner, ONEOK Partners GP, L.L.C., recommended and approved the engagement of PricewaterhouseCoopers LLP as our new independent registered public accounting firm. During our fiscal years ended December 31, 2006 and 2005, we did not consult PricewaterhouseCoopers LLP regarding the application of accounting principles to a specific transaction, either completed or proposed, or the type of audit opinion that might be rendered on our financial statements, management's assessment of the effectiveness of internal control over financial reporting, or the effectiveness of internal controls over financial reporting, nor did we consult PricewaterhouseCoopers LLP regarding any matter that was the subject of a disagreement (as defined in Item 304(a)(1)(iv) of Regulation S-K) or a reportable event (as described in Item 304(a)(1)(v) of Regulation S-K). |
