INFORMATION CONTAINED IN THIS FORM 6-K REPORT

Effective May 1, 2013 Seadrill Limited (the "Company") dismissed PricewaterhouseCoopers AS ("PwC Norway") as the Company's independent registered public accounting firm, in connection with the relocation of Seadrill Management to the United Kingdom.  The audit committee of the board of directors (the "Audit Committee") of the Company approved the dismissal of PwC Norway.

The reports of PwC Norway on the consolidated financial statements of the Company for the years ended December 31, 2012 and 2011 did not contain an adverse opinion or disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope, or accounting principles.

During the years ended December 31, 2012 and 2011 and through May 1, 2013, there were no disagreements with PwC Norway on any matter of accounting principles or practices, financial statement disclosures, or auditing scope or procedure, which such disagreements, if not resolved to the satisfaction of PwC Norway, would have caused PwC Norway to make reference thereto in its reports on the financial statements of the Company for such years.  During the years ended December 31, 2012 and 2011, and through the May 1, 2013, there were no "reportable events" as that term is described in paragraphs (A) through (D) of Item 16F(a)(1)(v) of Form 20-F.

The Company provided PwC Norway with a copy of the disclosure it is making in this Report of Foreign Private Issuer on Form 6-K (the "Report"), and requested that PwC Norway furnish the Company with a letter addressed to the Securities and Exchange Commission (the "SEC"), pursuant to Item 16F(a)(3) of Form 20-F, stating whether PwC Norway agrees with the statements made by the Company in this Report, and if not, the respects in which PwC Norway does not agree. A copy of PwC Norway's letter to the SEC dated September 20, 2013 is attached as Exhibit 1 to this Report.

On May 1, 2013, in connection with the relocation of the Company's corporate functions to the United Kingdom, the Audit Committee approved the appointment of PricewaterhouseCoopers LLP ("PwC UK"), effective May 1, 2013, as the Company's new independent registered public accounting firm for the fiscal year ending December 31, 2013.

During the years ended December 31, 2012 and 2011, and through May 1, 2013, neither the Company, nor anyone on its behalf, consulted PwC UK regarding either (i) the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered with respect to the financial statements of the Company; or (ii) any matter that was either the subject of a "disagreement," as that term is defined in Item 16F(a)(1)(iv) of Form 20-F and the related instructions to Item 16F of Form 20-F, or a "reportable event," as that term is described in Item 16F(a)(1)(v) of Form 20-F.
