Hedges (CICA Section 3865). The recommendations of CICA Section 3865, Hedges, replaces and expands the guidance in CICA Accounting Guideline 13 (AcG-13), Hedging Relationships, and the hedging guidance in CICA Section 1650, Foreign Currency Translation. CICA Section 3865 establishes standards for when and how hedge accounting may be applied as well as related disclosure requirements. Hedge accounting ensures the recording, in the same period, of counterbalancing gains, losses, revenues and expenses from designated derivative financial instruments as those related to the hedged item. NOVA Chemicals evaluated the impact of CICA Section 3865 on its Consolidated Financial Statements at Jan. 1, 2007, and determined that a gain on settlement of a derivative instrument that was previously designated as a hedge and deferred on the Consolidated Balance Sheets should now be reported as an adjustment of the previously hedged long-term debt instrument. As such, the deferred gain of $4 million was reclassified, on a prospective basis, from Accounts payable and accrued liabilities and Deferred credits and long-term liabilities to Long-term debt.

Comprehensive Income (CICA Section 1530). Adopted by NOVA Chemicals on Jan. 1, 2007, this standard establishes standards for reporting and presentation of comprehensive income (loss), which is defined as the change in equity from transactions and other events and circumstances from non-owner sources. As a result of adopting CICA Section 1530, two new statements, Consolidated Statements of Changes in Shareholders Equity and Consolidated Statements of Comprehensive Income (Loss), have been presented. Comprehensive income (loss) is composed of NOVA Chemicals net income (loss) and other comprehensive income (loss). Other comprehensive income (loss) includes unrealized gains (losses) on available-for-sale financial assets, foreign currency translation gains (losses) on the net investment in self-sustaining foreign operations and changes in the fair market value of derivative instruments designated as cash flow hedges (not including the amount of ineffectiveness, if any), all net of income taxes. The components of comprehensive income (loss) are disclosed in the Consolidated Statements of Changes in Shareholders Equity and Consolidated Statements of Comprehensive Income (Loss). As a result of the adoption of CICA Section 1530, the cumulative translation adjustment, formerly presented as a separate line item as part of Shareholders equity in the Consolidated Balance Sheets, of $378 million as of Dec. 31, 2006, (Dec. 31, 2005 - $324; Dec. 31, 2004 - $353) was reclassified to Accumulated other comprehensive income (AOCI).

Equity (CICA Section 3251). CICA Section 3251 establishes standards for the presentation of equity and changes in equity during the reporting periods. The requirements of this Section have been effected in the presentation of the Consolidated Statements of Changes in Shareholders Equity. This standard was adopted by NOVA Chemicals on Jan. 1, 2007.

Accounts Receivable Securitization (Europe). In the first quarter of 2007, NOVA Chemicals changed its accounting for its interest in the European accounts receivable securitization program, undertaken by the European joint venture. Accounts receivable securitization transactions are recorded as sales of assets based on the transfer of control to the purchaser as opposed to financing (Note 3).

Measurement Date. Effective Jan. 1, 2006, NOVA Chemicals changed the measurement date for reporting related to its defined benefit plans from Nov. 30 to Dec. 31. This change in measurement date has been used consistently in 2007 and will be for future periods. The change in measurement date had no significant impact on the 2006 Consolidated Financial Statements.

Stock-Based Compensation for Employees Eligible to Retire Before the Vesting Date (EIC 162). This standard, issued by the EIC, clarifies inconsistencies regarding accounting for stock-based awards granted to employees who are either eligible for retirement at the grant date or will be eligible before the end of the vesting period. Compensation costs for stock-based awards for employees eligible to retire at the grant date must be recognized at the grant date. Compensation costs for stock-based awards for employees who will become eligible to retire during the vesting period should be recognized over the period from the grant date to the date on which the employee becomes eligible to retire. Application of this standard has resulted in acceleration of the recognition of stock-based compensation expenses. EIC 162 was applied retroactively, with restatement of prior periods, and is effective for interim and annual periods ending on or after Dec. 31, 2006. Accordingly, NOVA Chemicals adopted EIC 162 in the fourth quarter of 2006. Prior periods presented were retrospectively adjusted, thereby reducing net loss in 2005 by $3 million ($0.04 per share diluted).

Accounting for Financial Instruments with Characteristics of Both Debt and Equity. On Jan. 1, 2005, the Corporation adopted new accounting standards as prescribed by the CICA, which harmonize accounting standards with U.S. GAAP for certain types of mandatorily redeemable shares and other financial instruments. Beginning on Jan. 1, 2005, these instruments were required to be reclassified, on a retroactive basis, as liabilities rather than equity. As a result, the
