The Canadian Accounting Standards Board (AcSB) has confirmed that the use of International Financial Reporting Standards(IFRS) will be required in 2011 for publicly accountable profit-oriented enterprises. IFRS will replace Canadas currentGAAP for those enterprises. These include listed companies and other profit-oriented enterprises that are responsible tolarge or diverse groups of stakeholders. The official changeover date is for interim and annual financial statements relatingto fiscal years beginning on or after Jan. 1, 2011. Companies will be required to provide comparative IFRS information forthe previous fiscal year. NOVA Chemicals is currently evaluating the impact of adopting IFRS.

U.S. GAAP

SFAS No. 157, Fair Value Measurements, defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. The statement applies also to other accounting pronouncements which require or permit fair value measurements. The standard is effective for fiscal years beginning after Nov. 15, 2007. NOVA Chemicals is evaluating the effects of adopting this standard.

SFAS No. 159, The Fair Value Option for Financial Assets and Financial Liabilities, including an amendment to SFAS No. 115, permits entities to choose to measure many financial instruments and certain other items at fair value. Most of the provisions of this Statement apply only to entities that elect the fair value option. However, the amendment to SFAS No. 115, Accounting for Certain Investments in Debt and Equity Securities, applies to all entities with available-for-sale and held-for-trading securities. SFAS No. 159 is effective as of the beginning of an entity’s first fiscal year that begins after Nov. 15, 2007. The adoption of this standard is not expected to have a material impact on NOVA Chemicals’ consolidated financial statements.

SFAS No. 141(R), Business Combinations and SFAS No. 160, Noncontrolling Interests in Consolidated Financial Statements. Effective for fiscal years beginning after Dec. 15, 2008, these standards will improve, simplify and converge internationally the accounting for business combinations and the reporting of noncontrolling interests in consolidated financial statements. SFAS No. 141(R) replaces SFAS No. 141, Business Combinations. SFAS No. 141(R) retains the fundamental requirements in SFAS No. 141 that the acquisition method of accounting (formerly called the purchase method) be used for all business combinations and for an acquirer to be identified for each business combination. The new statement improves reporting by creating greater consistency in the accounting and financial reporting of business combinations, resulting in more complete, comparable and relevant information for investors and other users of financial statements. To achieve this goal, the new standard requires the acquiring entity in a business combination to recognize all (and only) the assets acquired and liabilities assumed in the transaction; establishes the acquisition-date fair value as the measurement objective for all assets acquired and liabilities assumed; and requires the acquirer to disclose to investors and other users all of the information they need to evaluate and understand the nature and financial statement effect of the business combination. SFAS No. 160 amends Accounting Research Bulletin (ARB) No. 51, Consolidated Financial Statements, to establish accounting and reporting standards for the noncontrolling interests in a subsidiary and for the deconsolidation of a subsidiary. The new statement improves the relevance, comparability, and transparency of financial information provided to investors by requiring all entities to report noncontrolling (minority) interests in subsidiaries in the same way – as equity in the consolidated financial statements. In addition, SFAS No. 160 eliminates the diversity that currently exists in accounting for transactions between an entity and noncontrolling interests by requiring they be treated as equity transactions and changes the way the consolidated income statement is presented. NOVA Chemicals does not expect the adoption of these changes to have an impact on its current financial statements; however, these changes may affect potential future business.
