Item 1 — Information Contained in this Form 6-K Report
Attached as Exhibit I is a copy of an announcement of Teekay Tankers Ltd. (the “Company”), dated August 6, 2008.
On August 6, 2008, the Company’s Audit Committee and management concluded that the Company will restate financial results from 2003 through the end of the second quarter of 2008, including preliminary and previously announced results included in this earnings release, to adjust its accounting treatment for certain derivative transactions under SFAS 133.
The restatements will correct the Company’s accounting for certain of its interest rate swaps, foreign exchange forward contracts, and freight forward agreements used in its hedging strategies to manage interest rate, foreign currency, and tanker freight rate risks. To date, the Company has accounted for the applicable derivatives as hedging instruments in accordance with SFAS 133. The fair values of these derivatives were recorded as derivative assets and liabilities on the Company’s consolidated balance sheet, with the fair value changes each quarter recorded in accumulated other comprehensive income (loss). The Company recently discovered that since 2003 certain of its derivatives did not qualify for hedge accounting treatment under SFAS 133 because aspects of the Company’s hedge documentation did not meet the strict technical requirements of the standard. Accordingly, the Company will recognize changes in the fair value of these derivatives through the statement of income (loss) rather than as a component of accumulated other comprehensive income (loss) on the Company’s consolidated balance sheet and statement of changes in stockholders’ equity.
The Company believes that the applicable derivative transactions were consistent with its risk management policies and that its overall hedging strategy continues to be sound. The change to the accounting treatment for these transactions will not affect the economics of the derivative transactions nor the Company’s cash flows, liquidity, or total stockholders’ equity as at June 30, 2008. However, the restatements will result in greater fluctuations in reported net income for the restated periods and are expected to affect the preliminary financial results announced today for the three- and six-month periods ended June 30, 2008. The Company will finalize restatement amounts for the current period and applicable previous periods as soon as practicable and will release restated results and file amendments to its previous filings with the U.S. Securities and Exchange Commission as required. Accordingly, the Company’s previously reported financial statements for the periods from 2003 through the first quarter of 2008 should not be relied upon and the financial results included in this earnings release, which do not reflect the accounting adjustments described above, should be considered preliminary. Ernst & Young LLP, the Company’s independent registered public accounting firm, will complete its review of the financial statements as at June 30, 2008 and for the three-and six-month periods ended June 30, 2008 and 2007 following the completion of the restatements noted above.
The Company’s Audit Committee has discussed the matters related to the restatement with Ernst & Young LLP.
     Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned, thereunto duly authorized.
