NOVA Chemicals: Strong Cash Flow from Improved Operating Performance

PITTSBURGH, July 25 /CNW/ - NOVA Chemicals Corporation (NYSE:NCX)(TSX:NCX):

All financial information is in U.S. dollars unless otherwise indicated.

NOVA Chemicals Corporation (NOVA Chemicals) reported net income of $80 million ($0.96 per share diluted) for the second quarter of 2007. The results include after-tax restructuring charges totaling $9 million, or $0.11 per share diluted related to NOVA Chemicals' ongoing fixed cost reduction actions.

Net income for the second quarter compares to net income of $44 million ($0.53 per share diluted) for the first quarter of 2007 and net income of $106 million ($1.27 per share diluted) for the second quarter of 2006, which included a $60 million benefit related to Canadian tax rate reductions.

Net income in the second quarter improved relative to the first quarter due to significant margin improvement, particularly in the Olefins/Polyolefins business unit. While North American ethylene and polyethylene price increases were offset by higher feedstock costs on the U.S. Gulf Coast, NOVA Chemicals' feedstock costs increased only slightly quarter-over-quarter resulting in improved margins. The Alberta Advantage increased from an average of 7 cents per pound in the first quarter to 13 cents per pound in the second quarter, and widened to approximately 17 cents per pound in July.

"Our businesses delivered $251 million of EBITDA in the second quarter, which resulted in $115 million in cash from operations," said Jeff Lipton, NOVA Chemicals' President and CEO. "Market conditions and our margins in Olefins and Polyolefins improved each month during the second quarter and are improving further into the third quarter. In addition, our Alberta feedstock advantage is widening again as it did last summer."

After significantly appreciating in the first quarter, the value of NOVA Chemicals' Corunna feedstock open positions did not change significantly in the second quarter. As a result, the mark-to-market impact of these open positions was a $1 million loss in this quarter compared to a $26 million gain in the first quarter. These mark-to-market gains and losses are reflected in the Corporate results.

Review of Operations

Olefins/Polyolefins

The Olefins/Polyolefins business unit reported EBITDA of $228 million in the second quarter of 2007, a significant improvement from $159 million in the first quarter. The quarter-over-quarter improvement was primarily due to higher selling prices for ethylene, polyethylene, and co-products that outpaced higher feedstock costs. First quarter results were impacted by the Canadian National rail strike which reduced EBITDA by $12 million.

Joffre Olefins

Second Quarter 2007 Versus First Quarter 2007

The Joffre Olefins segment reported EBITDA of $121 million in the second quarter of 2007 compared to $107 million in the first quarter of 2007. The quarter-over-quarter increase in EBITDA was primarily due to higher ethylene selling prices which were partially offset by higher feedstock costs.

USGC ethylene benchmark prices averaged 45 cents per pound in the second quarter of 2007 compared to 40 cents per pound in the first quarter of 2007.

Joffre Olefins' ethane feedstock costs increased slightly from last quarter due to higher Alberta natural gas prices, which were up 2% from last quarter. In comparison, USGC ethane prices were 23% higher relative to the first quarter. USGC ethane prices rose sharply in the second quarter as ethane demand strengthened due to higher prices for competing ethylene feedstocks such as naphtha.

As a result, the Alberta Advantage averaged 13 cents per pound in the second quarter, up from 7 cents per pound in the first quarter. The Alberta Advantage is approximately 17 cents per pound in July. NOVA Chemicals uses ethylene produced at its Joffre, Alberta, facility to make approximately 65% of its polyethylene.

Second Quarter 2007 Versus Second Quarter 2006

The Joffre Olefins segment reported EBITDA of $121 million in the second quarter of 2007 compared to $134 million in the second quarter of 2006. This decrease was primarily due to higher feedstock costs and was partially offset by higher ethylene and co-product selling prices. The AECO spot natural gas price was 20% higher in the second quarter of 2007 versus the same quarter one year ago.

Six Months Ended June 30, 2007 Versus Six Months Ended June 30, 2006

The Joffre Olefins segment reported EBITDA of $228 million for the six months ended June 30, 2007 compared to $295 million for the six months ended June 30, 2006. This decrease was primarily due to lower ethylene selling prices and higher feedstock costs. AECO cash gas prices were 7% higher in the first six months of 2007 compared to the same period last year. Industry ethylene selling prices were 13% lower in the first half of 2007 than in the first half of 2006, as prices remained elevated in early 2006 in the aftermath of Hurricane Katrina.

Corunna Olefins

Second Quarter 2007 Versus First Quarter 2007

The Corunna Olefins segment reported EBITDA of $58 million in the second quarter of 2007, the highest EBITDA since the third quarter of 2000. The second quarter's results compare to EBITDA of $42 million in the first quarter of 2007, which included a net gain of $27 million from the propane and butane feedstock purchase program. The quarter-over-quarter improvement was primarily due to stronger co-product sales volume. Higher selling prices for ethylene and co-products offset higher feedstock costs.

In the second quarter, co-product selling prices were 13% higher than the first quarter. Chemical co-product pricing and volumes improved due to strong demand for propylene and butadiene, while energy co-products pricing and volumes were up due to strong demand for distillate and gasoline blending components.

Corunna's average feedstock costs were higher in the second quarter than in the first quarter. NOVA Chemicals' average crude oil costs were up 11% compared to the first quarter. In addition, higher propane and butane feedstock costs in the second quarter and reduced gains from NOVA Chemicals' feedstock purchasing program contributed to the quarter-over-quarter increase in feedstock costs.

Second Quarter 2007 Versus Second Quarter 2006

The Corunna Olefins segment reported EBITDA of $58 million in the second quarter of 2007 compared to $41 million in the same period one year ago. EBITDA improved due to higher co-product selling prices, lower feedstock costs, and improved operations at the Corunna ethylene flexi-cracker. NOVA Chemicals' average crude oil prices were 2% lower in the second quarter of 2007 compared to the second quarter of 2006. Weighted average co-product prices were 10% higher this quarter compared to the same period last year.

Six Months Ended June 30, 2007 Versus Six Months Ended June 30, 2006

The Corunna Olefins segment reported EBITDA of $100 million for the six months ended June 30, 2007 compared to $61 million to the same period last year. The improvement was due primarily to lower feedstock costs and improved operations at the Corunna flexi-cracker, which more than offset lower ethylene selling prices.

Polyethylene

Second Quarter 2007 Versus First Quarter 2007

The Polyethylene segment reported EBITDA of $50 million in the second quarter of 2007 compared to $22 million in the first quarter. The quarter-over-quarter improvement in EBITDA was primarily due to higher average selling prices and sales volumes, which were offset by higher feedstock costs.

The North American industry butene liner polyethylene price averaged 62 cents per pound in the second quarter, up 6 cents per pound from the first quarter. Improved domestic demand and very strong export sales enabled producers, including NOVA Chemicals, to operate at high utilization rates, reduce inventory, and increase prices during the quarter.

NOVA Chemicals' total polyethylene sales volume for the second quarter was 830 million pounds, up 4% from the previous quarter. Improved seasonal sales volumes in the second quarter and reduced shipments in the first quarter related to the Canadian National rail strike contributed to the quarter-over-quarter increase.

International sales volume represented approximately 17% of total sales, the same high level as in the first quarter of 2007. Strong international polyethylene pricing in the second quarter, driven by higher global production costs and robust demand, continued to create profitable export opportunities. NOVA Chemicals expects these opportunities to continue in the third quarter.

According to data reported by the American Chemistry Council (ACC), North American polyethylene demand improved quarter-over-quarter and inventories fell, despite higher producer operating rates. Producer sales were up 3% from the first quarter driven by growth in both domestic and export sales volumes. Average producer operating rates increased to 96% in the second quarter, up from 93% in the first quarter, while inventories fell by 11 million pounds during the second quarter. NOVA Chemicals ended the second quarter with 19 days of polyethylene inventory, down from 21 days at the end of the first quarter and well below the company's historical average of 24 days.

Total sales volumes of polyethylene manufactured using Advanced SCLAIRTECH(TM) technology in the second quarter were up 16% relative to the first quarter. The quarter-over-quarter sales improvement was mainly due to the commercialization of new products. Margins expanded during the second quarter due to price increase implementation, product mix improvements, improved operations, and lower operating costs. In addition, export markets in the second quarter provided margins superior to those in North America for several applications.

During the second quarter, NOVA Chemicals completed the implementation of a 6 cents per pound price increase for all grades of polyethylene, which was initiated in the first quarter. In addition, NOVA Chemicals implemented a 4 cents per pound price increase for standard grades and a 6 cents per pound price increase for higher-value hexene- and octene-based grades.

NOVA Chemicals is currently implementing a 5 cents per pound polyethylene price increase, originally announced for June 1, and has announced a 4 cents per pound price increase effective August 1.

Second Quarter 2007 Versus Second Quarter 2006

The Polyethylene segment reported EBITDA of $50 million in the second quarter of 2007 compared to EBITDA of $51 million in the second quarter of 2006. Industry ethylene feedstock costs were 4% lower this quarter compared to the same quarter last year. The industry average butene liner polyethylene price was 62 cents per pound in the second quarter of 2007 compared to 63 cents per pound in the second quarter of 2006.

Six Months Ended June 30, 2007 Versus Six Months Ended June 30, 2006

The Polyethylene segment reported EBITDA of $72 million for the six months ended June 30, 2007 compared to $66 million for the same period last year. The year-over-year improvement was primarily due to higher sales volumes and improvements in plant operation. Average unit margins were similar during the two periods.

NOVA Chemicals' ability to implement announced price increases depends on many factors that may be beyond its control. See Forward-Looking Information on page 16.

Review of Operations

Performance Styrenics

Second Quarter 2007 Versus First Quarter 2007

The Performance Styrenics segment reported an EBITDA loss of $6 million in the second quarter of 2007, the same loss recorded in the first quarter.

Sales of expandable polystyrene (EPS) in the second quarter were 22% higher than the first quarter due to improved demand from the construction, cup, and produce box segments. Styrene monomer prices were up 9%. Improvements in EPS margins in the second quarter were offset by weaker ZYLAR(R) and NAS(R) margins.

During the second quarter, NOVA Chemicals implemented EPS price increases that totaled 4 cents per pound.

In the second quarter, NOVA Chemicals received its first revenue from the sale of Elemix(TM) admixture, which includes a proprietary styrenic additive, that is able to reduce the weight of concrete by up to 25% without sacrificing structural strength.

Second Quarter 2007 Versus Second Quarter 2006

The Performance Styrenics segment reported an EBITDA loss of $6 million in the second quarter of 2007 compared to break even in the second quarter of 2006. The loss is largely due to higher industry styrene monomer feedstock costs, which were 15% higher in the second quarter of 2007 relative to the same period last year.

Six Months Ended June 30, 2007 Versus Six Months Ended June 30, 2006

The Performance Styrenics segment reported an EBITDA loss of $12 million for the six months ended June 30, 2007 compared to an EBITDA loss of $1 million for the six months ended June 30, 2006. This increase in EBITDA loss was primarily due to the impact of higher styrene monomer costs.

NOVA Chemicals' ability to implement announced price increases depends on many factors that may be beyond its control. See Forward-Looking Information on Page 16.

Review of Operations

STYRENIX

The STYRENIX business unit reported EBITDA of $29 million in the second quarter of 2007, a $10 million improvement over the first quarter. The quarter-over-quarter improvement was primarily due to higher styrene monomer prices, which more than offset higher benzene and ethylene feedstock costs and lower sales volume.

Through the first half of 2007, the STYRENIX business unit reported EBITDA of $48 million, a $74 million improvement from the EBITDA loss of $26 million for the same period last year. The year-over-year improvement is primarily due to lower costs as a result of NOVA Chemicals' restructuring actions and better styrene monomer and European polystyrene market conditions.

Styrene Monomer

Second Quarter 2007 Versus First Quarter 2007

The Styrene Monomer segment reported EBITDA of $23 million in the second quarter compared to $10 million in the first quarter. The improvement was primarily due to higher margins despite higher benzene and ethylene feedstock costs.

Styrene monomer prices rose 9%, driven primarily by sharply higher benzene and ethylene costs. Tight market conditions in Europe, which allowed for profitable export opportunities, also contributed to the increase in styrene monomer prices. Industry average benzene costs were 12% higher in the second quarter; however, NOVA Chemicals benzene costs were only up 5% due to its use of FIFO accounting.

Third party sales volumes were 19% lower in the second quarter. Domestic styrene monomer prices increased during the quarter and were higher than Asian prices, resulting in fewer export opportunities to Asia compared to the prior quarter. The reduction in export sales to Asia more than offset increased domestic and European export sales volumes.

During the second quarter, NOVA Chemicals implemented three styrene monomer price increases that totaled 10 cents per pound.

Second Quarter 2007 Versus Second Quarter 2006

The Styrene Monomer segment reported EBITDA of $23 million in the second quarter of 2007 compared to an EBITDA loss of $4 million in the second quarter of 2006. The improvement was primarily due to higher styrene monomer margins and lower costs related to NOVA Chemicals' restructuring activities.

Six Months Ended June 30, 2007 Versus Six Months Ended June 30, 2006

The Styrene Monomer segment reported EBITDA of $33 million for the six months ended June 30, 2007 compared to an EBITDA loss of $6 million for the six months ended June 30, 2006. The improvement was primarily due to improved market conditions.

North American Solid Polystyrene

Second Quarter 2007 Versus First Quarter 2007

The North American Solid Polystyrene segment reported an EBITDA loss of $7 million in the second quarter of 2007 compared to an EBITDA loss of $6 million in the first quarter of 2007.

Industry styrene monomer feedstock costs were 9% higher quarter-over-quarter, while industry average selling prices for solid polystyrene (PS) were only up 5% relative to the first quarter. In addition, North American solid PS sales volume in the second quarter was 4% lower than the first quarter as customers reduced purchases and consumed inventory in response to higher polymer prices.

Second Quarter 2007 Versus Second Quarter 2006

The North American Solid Polystyrene segment reported an EBITDA loss of $7 million in the second quarter of 2007, compared to an EBITDA loss of $8 million in the second quarter of 2006. The improvement from the same period one year ago was due to lower costs related to NOVA Chemicals' restructuring activities.

Six Months Ended June 30, 2007 Versus Six Months Ended June 30, 2006

The North American SPS segment reported an EBITDA loss of $13 million for the six months ended June 30, 2007, the same as the six months ended June 30, 2006.

European Joint Venture

Second Quarter 2007 Versus First Quarter 2007

NOVA Chemicals' 50% share of the European Joint Venture provided EBITDA of $13 million in the second quarter of 2007, down slightly from EBITDA of $15 million in the first quarter of 2007.

Total polymer sales volumes for the European Joint Venture were 3% lower than the first quarter due to softer demand in the solid PS and EPS markets.

Second Quarter 2007 Versus Second Quarter 2006

The European Joint Venture segment provided EBITDA of $13 million in the second quarter of 2007 compared to an EBITDA loss of $3 million in the second quarter of 2006. Results improved from the same period one year ago due to cost reductions resulting from the realization of synergies and better market conditions.

Six Months Ended June 30, 2007 Versus Six Months Ended June 30, 2006

The European Joint Venture segment provided EBITDA of $28 million for the six months ended June 30, 2007 compared to an EBITDA loss of $7 million for the six months ended June 30, 2006. This improvement was due to cost reductions resulting from the realization of synergies and better market conditions.

Expansion of Joint Venture with INEOS for STYRENIX

As previously announced in March 2007, NOVA Chemicals and INEOS signed a letter of intent to expand the companies' existing joint venture in Europe to include North American styrene and polystyrene assets. The proposed expanded joint venture will be known as INEOS NOVA.

By June 6, 2007, NOVA Chemicals and INEOS had announced the members of the senior leadership team and announced that the headquarters for the proposed expanded joint venture will be in Joliet, Illinois, which is also the location of the proposed expanded joint venture's largest polymer plant.

The current cost-reduction target for INEOS NOVA is $50 million per year. The transaction to form the expanded joint venture is expected to close in the third quarter of 2007, subject to approvals and completion of definitive agreements.

(1) Beginning in the first quarter of 2007, NOVA Chemicals no longer
 allocates interest, taxes or corporate operating costs to the
 business segments. Prior period comparative amounts have been revised
 to reflect this change. Operating costs include corporate
 depreciation.

(2) NOVA Chemicals has two cash-settled, stock-based incentive
 compensation plans that are marked to market with changes in the
 value of the common stock price. In November 2005, NOVA Chemicals
 entered into a hedging arrangement that effectively neutralizes the
 mark-to-market impact on the stock-based incentive compensation
 plans. Stock-based compensation also includes the amount expensed
 related to the fair value of stock options earned by employees during
 the period. In addition, NOVA Chemicals maintains a profit sharing
 program available to most employees based on the achievement of
 shareholder return on equity targets.

(3) NOVA Chemicals is required to record on its balance sheet the
 market value of its open derivative positions. The gain or loss
 resulting from changes in the market value of these derivatives is
 recorded as earnings each period. These mark-to-market adjustments
 are recorded as part of Corporate results until the positions are
 realized. Once realized, any income effects are recorded in business
 results.

Corporate Operating Costs

The corporate operating costs of $26 million in the second quarter of 2007, are similar to those in the first quarter and are $7 million lower than the second quarter of 2006 primarily from cost savings related to NOVA Chemicals' restructuring activities. The corporate operating costs for the six months ended June 30, 2007 are lower than the same period in the prior year, also as a result of NOVA Chemicals' restructuring activities.

Stock-based Compensation and Profit Sharing

In the second quarter of 2007, the stock-based compensation costs of $6 million were lower than the $18 million reported in the first quarter of 2007. The first quarter expense included a stock-based compensation charge of approximately $10 million due to the acceleration of stock-based compensation expenses for retirement eligible employees. See the last paragraph on page 22 for more details.

Restructuring

In the second quarter of 2007, NOVA Chemicals accrued $7 million ($7 million after-tax - see Note 5 on page 24) of restructuring costs related to the May 31 announcement of the elimination of approximately 90 positions in the U.S. and Europe. This action is expected to lower costs by $12 million per year. In addition, NOVA Chemicals accrued $3 million ($2 million after-tax) of restructuring costs related to additional actions taken in the European Joint Venture.

In the second quarter of 2006, NOVA Chemicals accrued $1 million of restructuring costs related to actions taken by the European Joint Venture. These actions were part of a larger plan, which included two European EPS site closures, towards achieving an expected $80 million per year in joint venture synergies by 2008. NOVA Chemicals receives 50% of the benefit of the total costs savings of the European Joint Venture.

In the first quarter of 2006, NOVA Chemicals accrued $15 million related to severance costs for the Chesapeake, VA plant site closure. The closure of the Chesapeake, VA plant has resulted in cost reductions of approximately $15 million per year.

Mark-to-Market Feedstock Derivatives

In the second quarter of 2007, the mark-to-market impact of NOVA Chemicals' open feedstock derivatives was a $1 million loss (before- and after-tax), compared to a $26 million ($17 million after-tax) gain in the first quarter, resulting in a $27 million ($18 million after-tax) unfavorable impact quarter-over-quarter. After significantly appreciating in the first quarter, the value of these positions did not change significantly in the second quarter.

(1) Current debt includes the $198 million preferred shares of NOVA
 Chemicals' subsidiary due Oct. 31, 2007. Current debt also includes
 the current debt related to the Joffre co-generation facility joint
 venture, the current portion of the Corunna compressor capital lease,
 the secured revolver and bank loans.
(2) Maturity dates for NOVA Chemicals' current and long-term debt
 range from October 2007 to August 2028.
(3) As a result of adopting new Canadian GAAP pronouncements under
 CICA Section 3855 on Jan. 1, 2007, long-term debt is required to be
 initially measured at fair value and subsequently measured at
 amortized cost. As a result, $7 million of deferred debt discount and
 issuance costs that were reported in Restricted cash and other assets
 prior to January 1, 2007, on the Consolidated Balance Sheets were
 reclassified in the first quarter, on a prospective basis, and are
 now reported as a reduction of the respective debt obligations.
(4) Net current debt equals current debt less restricted cash and
 other assets (see Supplemental Measures on page 13).
(5) Common shares outstanding on July 20, 2007 were 82,959,118.
(6) A total of 4,765,646 stock options to purchase common shares of
 NOVA Chemicals were outstanding to officers and employees on July 20,
 2007, and 4,843,459 were outstanding on June 30, 2007. A total of
 2,525,842 common shares were reserved but unallocated at June 30,
 2007. A total of 13 million common shares were initially reserved for
 issuance under the Option Plan.
(7) A total of 47,800 shares were reserved for the Directors' Share
 Compensation Plan.
(8) In April 2005, NOVA Chemicals' shareholders reconfirmed a
 shareholder rights plan where one right was issued for each
 outstanding common share. The plan expires in May 2009.
(9) Total capitalization includes shareholders' equity and total debt,
 net of cash, cash equivalents, and restricted cash and other assets
 (see Supplemental Measures on page 13).
(10) Net debt to total capitalization is equal to total debt, net of
 cash, cash equivalents, and restricted cash and other assets, divided
 by total common shareholders' equity plus net debt (see

(1) See Consolidated Statements of Net Income on page 17 and
 Supplemental Measures below.

 carrying amount resulting from the application of new Canadian GAAP
 pronouncements (see Note 1 to the Consolidated Financial Statements).

NOVA Chemicals' funds from operations were $160 million for the second quarter of 2007, up significantly from $62 million in the first quarter. Cash flow from operating activities increased to $115 million in the second quarter despite a $45 million investment in working capital and other, which increased primarily due to higher feedstock inventory. As part of Corunna's flexi-cracker optimization program, seasonally lower cost feedstock inventory was built to be consumed during the winter months.

NOVA Chemicals measures the effectiveness of its working capital management through Cash Flow Cycle Time (CFCT). See Supplemental Measures below. CFCT was 32 days as of June 30, 2007, and 31 days as of Mar. 31, 2007.

Supplemental Measures

In addition to providing measures in accordance with Canadian Generally Accepted Accounting Principles (GAAP), NOVA Chemicals presents certain supplemental measures as follows:

-- Adjusted EBITDA - This measure, defined on page 2, is provided to assist investors in determining the ability of NOVA Chemicals to generate cash from operations.

-- After-tax return on capital employed - defined on page 3.

-- Average capital employed - defined on page 3.

-- Cash Flow Cycle Time - This measures working capital from operations (excluding the European Joint Venture) in terms of the number of day's sales, calculate as working capital from operations divided by average daily sales. This metric helps to determine which portion of changes in working capital results from factors other than price movements. See above.

-- EBITDA - This measure, defined on page 4, is provided to assist investors in determining the ability of NOVA Chemicals to generate cash from operations.

-- EBITDA from the businesses - This measure, defined on page 2, highlights the ongoing performance of the business units without considering one-time charges, events or other items which are not driven by the business units.

-- Funds from operations - See Funds Flow and Changes in Cash and Debt above for a reconciliation to operating income.

-- Net current debt - defined on page 12.

-- Net debt to total capitalization - defined on page 12.

-- Total capitalization - defined on page 12.

These measures do not have any standardized meaning prescribed by GAAP and are therefore unlikely to be comparable to similar measures presented by other companies.

Financing

NOVA Chemicals has four revolving credit facilities aggregating $590 million. The amounts and expiration dates of these facilities are as follows:

-- $100 million on Dec. 31, 2007

-- $ 65 million on Mar. 20, 2010

-- $325 million on June 30, 2010, and

-- $100 million on Mar. 20, 2011.

As of June 30, 2007, NOVA Chemicals had utilized $191 million of the facilities (of which $50 million was in the form of letters of credit), a $27 million reduction in the utilization of the facilities from Mar. 31, 2007.

NOVA Chemicals amended its financial covenants governing these credit facilities to allow for an exemption of any write-down of the STYRENIX assets up to $950 million, of which $860 million occurred in the fourth quarter of 2006. In addition, the debt-to-capitalization ratio financial covenant was raised from 55% to 60%. These amendments are in effect for the period Dec. 31, 2006 to Mar. 30, 2008. Using the covenant methodology in the relevant revolving credit facilities, the debt-to-capitalization ratio was 50% at June 30, 2007. NOVA Chemicals continues to comply with all financial covenants under the applicable facilities.

NOVA Chemicals also has $350 million accounts receivable securitization programs that expire on June 30, 2010. As of June 30, 2007 and Mar. 31, 2007, $307 million and $267 million, respectively, was sold under the accounts receivable securitization programs.

The European Joint Venture has a EUR 120 million accounts receivable securitization program that expires in November 2011. As of June 30, 2007 and Mar. 31, 2007, NOVA Chemicals' 50% share, $60 million and $50 million, respectively, was sold under the accounts receivable securitization program.

Feedstock Derivative Positions

NOVA Chemicals maintains a derivatives program to manage risk associated with its feedstock purchases. In the second quarter, NOVA Chemicals recorded a net after-tax gain of $3 million on realized positions compared to a net after-tax gain of $18 million in the first quarter. In both quarters, $1 million of the total after-tax gain was related to benzene positions, the remaining gain was attributable to feedstock positions at Corunna.

Mark-to-market adjustments, related to the change in the value of open feedstock positions, are recorded as part of Corporate results until the positions are realized. Once realized, any income effects are recorded in business results. See page 11 for more details.

FIFO Impact

NOVA Chemicals uses the first-in, first-out (FIFO) method of valuing inventory. Most of NOVA Chemicals' competitors use the last-in, first-out (LIFO) method. Because NOVA Chemicals uses FIFO, a portion of the first quarter 2007 feedstock purchases flowed through the Consolidated Statements of Net Income in the second quarter of 2007.

NOVA Chemicals estimates that earnings would have been about $35 million lower (after-tax) in the second quarter had it used the LIFO method of accounting. The increase in FIFO impact was due primarily to sharp increases in both benzene and crude oil feedstock costs during the second quarter.

NOVA Chemicals' share price on the New York Stock Exchange (NYSE) rose to $35.57 at June 30, 2007 from $30.96 at Mar. 31, 2007. NOVA Chemicals' share value increased 15% for the quarter ending June 30, 2007 on the NYSE and 7% on the Toronto Stock Exchange (TSX). Peer chemical companies' share values increased 7% on average and the S&P Chemicals Index increased 6%. The S&P/TSX Composite Index was up 6% and the S&P 500 was up 6% in the second quarter of 2007 compared to the first quarter of 2007. As of July 24, 2007, NOVA Chemicals' share price was $39.05, up 10% from June 30, 2007. The S&P Chemicals Index was up 3% during the same period.

In the second quarter, approximately 40% of trading in NOVA Chemicals'
 shares took place on the TSX and 60% of trading took place on the
 NYSE and other U.S. markets.

(1) Operating margin equals revenue less feedstock and operating
 costs.

Operating margins in the second quarter of 2007 were $60 million higher than first quarter primarily due to margin expansion in ethylene, polyethylene and styrene monomer.

Depreciation and amortization in the second quarter of 2007 was $6 million higher than the first quarter of 2007. Depreciation and amortization in the second quarter of 2007 and the first six months of 2007 was lower than the comparable three and six-month periods in 2006 as a result of writing down the STYRENIX assets in late 2006 in connection with NOVA Chemicals' restructuring actions.

In the second quarter of 2006, NOVA Chemicals recorded an income tax benefit of $60 million to reflect the Canadian federal and Alberta provincial income tax rate reductions. As a result, the second quarter of 2007 compared to the second quarter of 2006 and the first six months of 2007 compared to the first six months of 2006 reflect higher income tax expense.

Refer to Note 3 on page 23 for details related to the restructuring charges.

There were no significant changes in internal controls during the second quarter of 2007.

Forward-Looking Information

This news release contains forward-looking statements with respect to NOVA Chemicals, its subsidiaries and affiliated companies. By their nature, forward-looking statements require NOVA Chemicals to make assumptions and are subject to inherent risks and uncertainties. There is significant risk that predictions, forecasts, conclusions and projections will not prove to be accurate, that NOVA Chemicals' assumptions may not be correct and that actual results may differ materially from such predictions, forecasts, conclusions or projections. Forward-looking statements for the time periods beyond 2007 involve longer-term assumptions and estimates than forward-looking statements for 2007 and are consequently subject to greater uncertainty. NOVA Chemicals cautions readers of this news release not to place undue reliance on its forward-looking statements as a number of factors could cause actual results, conditions, actions or events to differ materials from the targets, expectations, estimates or intentions expressed in the forward-looking statements.

The words "believe", "expect", "plan", "intend", "estimate", or "anticipate" and similar expressions, as well as future or conditional verbs such as "will", "should", "would", and "could" often identify forward-looking statements. Specific forward-looking statements contained in this news release include, among others, statements regarding: NOVA Chemicals' beliefs about market conditions in Olefins and Polyolefins and the widening of its Alberta feedstock advantage; NOVA Chemicals' expectation that strong international polyethylene pricing, driven by higher global production costs and robust demand will create profitable export opportunities in the third quarter; NOVA Chemicals' beliefs about its proposed expanded joint venture with INEOS, including the target for cost reductions of $50 million and the expected closing date for the transaction; and NOVA Chemicals' expectation that the European Joint Venture synergies will be $80 million per year by 2008. With respect to forward-looking statements contained in this news release, NOVA Chemicals has made assumptions regarding, among other things: future oil, natural gas and benzene prices; its ability to obtain raw materials; its ability to market products successfully to its anticipated customers; the impact of increasing competition; and its ability to obtain financing on acceptable terms. Some of the risks that could affect NOVA Chemicals' future results and could cause results to differ materially from those expressed in the forward-looking statements include: commodity chemicals price levels (which depend, among other things, on supply and demand for these products, capacity utilization and substitution rates between these products and competing products); feedstock availability and prices; operating costs; terms and availability of financing; technology developments; currency exchange rate fluctuations; starting up and operating facilities using new technology; realizing synergy and cost savings targets; NOVA Chemicals' ability to implement its business strategies; meeting time and budget targets for significant capital investments; avoiding unplanned facility shutdowns; safety, health, and environmental risks associated with the operation of chemical plants and marketing of chemical products, including transportation of these products; public perception of chemicals and chemical end-use products; the impact of competition; changes in customer demand, including customer acceptance of NOVA Chemicals' Performance Products; changes in, or the introduction of new laws and regulations relating to NOVA Chemicals' business, including environmental, competition and employment laws; loss of the services of any of NOVA Chemicals' executive officers; uncertainties associated with the North American, South American, European, and Asian economies, terrorist attacks, severe weather events, and other risks detailed from time to time in the publicly filed disclosure documents and securities commission reports of NOVA Chemicals and its subsidiaries or affiliated companies.

Implementation of announced price increases depends on many factors, including market conditions, the supply/demand balance for each particular product and feedstock costs. Price increases have varying degrees of success. They are typically phased in and can differ by product or market. There can be no assurances that any announced price increases will be successful or will be realized within the anticipated time frame. In addition, benchmark price indices sometimes lag price increase announcements due to the timing of publication.

NOVA Chemicals' forward-looking statements are expressly qualified in their entirety by this cautionary statement. In addition, the forward-looking statements are made only as of the date of this news release, and except as required by applicable law, NOVA Chemicals undertakes no obligation to publicly update these forward-looking statements to reflect new information, subsequent events or otherwise.

Notes to Consolidated Financial Statements

(unaudited, millions of U.S. dollars, except per share amounts and unless otherwise noted)

These interim Consolidated Financial Statements do not include all of the disclosures included in NOVA Chemicals' annual Consolidated Financial Statements. Accordingly, these interim Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements for the year ended Dec. 31, 2006.

1. Significant Accounting Policies

These interim Consolidated Financial Statements have been prepared in accordance with Canadian GAAP, using the same accounting policies as set out in Note 2 to the Consolidated Financial Statements for the year ended Dec. 31, 2006 on pages 80 to 84 of the 2006 Annual Report, except as follows.

On Jan. 1, 2007, NOVA Chemicals adopted the Canadian Institute of Chartered Accountants (CICA) Handbook Section 1506, Accounting Changes. CICA Section 1506 provides that an entity is permitted to change accounting policies only when it is required by a primary source of GAAP, or when the change results in a reliable and more relevant presentation in the financial statements. This new standard applies to fiscal years beginning on or after Jan. 1, 2007.

On Jan. 1, 2007, NOVA Chemicals adopted CICA Section 3855, Financial Instruments - Recognition and Measurement; Section 3865, Hedges; Section 1530, Comprehensive Income; Section 3251, Equity. These new standards apply to fiscal years beginning on or after Oct. 1, 2006. In addition, NOVA Chemicals has adopted the related disclosure and presentation changes as contained in the existing CICA Section 3861, Financial Instruments - Disclosure and Presentation.

CICA Section 3855 establishes standards for recognizing and measuring financial assets, financial liabilities and non-financial derivatives. Under CICA Section 3855, all financial assets must be classified as either held-for-trading, available for sale, held to maturity investments or loans and receivables. All financial liabilities must be classified as held-for-trading or other financial liabilities. All financial instruments, including derivatives, are included on the Consolidated Balance Sheets and are measured at fair value, except for held to maturity investments, loans and receivables and other financial liabilities, which are measured at amortized cost. Subsequent measurement and recognition of changes in fair value depend on the instrument's initial classification. Held-for-trading financial instruments are measured at fair value and all gains and losses are included in net income in the period in which they arise. Available for sale financial instruments are measured at fair value, determined by published market prices in an active market, except for investments in equity instruments that do not have quoted market prices in an active market which are measured at cost. Changes in fair value are recorded in other comprehensive income until the assets are removed from the balance sheet. Investments classified as available for sale are written down to fair value through income whenever it is necessary to reflect other-than-temporary impairment. Realized gains and losses on the disposal of available for sale securities, are recognized in other gains and losses. Also, transaction costs related to all financial assets and liabilities are added to the acquisition or issue cost, unless the financial instrument is classified as held-for-trading, in which case the transaction costs are recognized immediately in net income.

CICA Section 3855 also requires financial and non-financial derivative instruments to be measured at fair value and recorded as either assets or liabilities, with the exception of non-financial derivative contracts that were entered into and continue to be held for the purpose of receipt or delivery of a non-financial item in accordance with NOVA Chemicals' expected purchase, sale or usage requirements. Certain derivatives embedded in non-derivative contracts must also be measured at fair value. Any changes in the fair value of recognized derivatives are included in net income in the period in which they arise, unless specific hedge accounting criteria are met, as defined in CICA Section 3865. As a result, NOVA Chemicals has reflected an unrealized loss of $1 million ($0.01 loss per share diluted) and an unrealized gain of $26 million ($0.20 per share diluted) for the periods ended June 30, 2007 and Mar. 31, 2007, respectively, which is included in feedstock and operating costs on the Consolidated Statements of Income. Fair values for NOVA Chemicals' recognized commodity-based derivatives are based on the forward prices of the associated market index. No non-financial derivatives have been recognized as a result of the application of this standard, as all of NOVA Chemicals' non-financial derivative contracts have been designated and documented as meeting NOVA Chemicals' expected purchase, sale or usage requirements.

As a result of the adoption of CICA Section 3855, NOVA Chemicals has classified, at June 30, 2007 and Mar. 31, 2007, its financial instruments as follows: cash and cash equivalents, derivative instruments (included in Accounts receivables, Investments and other assets and Deferred credits and long-term liabilities on the Consolidated Balance Sheets) as held-for-trading; trade accounts receivable, advances receivable from affiliates and other receivables (included in Accounts receivable on the Consolidated Balance Sheets) and Restricted cash and other assets as loans and receivables; investments in non-affiliated entities (included in Investments and other assets on the Consolidated Balance Sheets) as available for sale; and trade accounts payable, other accounts payable, certain accrued liabilities (included in Accounts payable and accrued liabilities on the Consolidated Balance Sheets); bank loans (line of credit); long-term liabilities (included in Deferred credits and long-term liabilities on the Consolidated Balance Sheets); and long-term debt as other financial liabilities.

Under CICA Section 3855, long-term debt is required to be initially measured at fair value and subsequently measured at amortized cost. As a result, certain deferred debt discount and issuance costs that were previously reported in Restricted cash and other assets and Investments and other assets on the Consolidated Balance Sheets have been reclassified, on a prospective basis, and are now reported as a reduction of the respective debt obligations. In total, $17 million was reclassified in the first quarter of 2007.

As noted above, investments in non-affiliated entities classified as available for sale are now measured at fair market value. Previously, these investments were measured at cost. On Jan. 1, 2007, the impact of this change was not material to the Consolidated Financial Statements. During the three-month periods ending June 30, 2007 and Mar. 31, 2007, the change in fair value of these investments was also not material to the Consolidated Financial Statements. NOVA Chemicals' investments in non-affiliated entities that do not have a quoted market price in an active market are measured at cost. As of Mar. 31, 2007 and June 30, 2007 these investments totaled $13 million and $12 million, respectively. During the second quarter, an impairment loss of $1 million was recognized related to one of these investments.

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, Mar. 31, 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.

CICA Section 1530, Comprehensive Income, establishes standards for reporting and presentation of comprehensive income, 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 have been presented. Comprehensive income is composed of NOVA Chemicals' net income 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, all net of income taxes. The components of comprehensive income are disclosed in the Consolidated Statements of Changes in Shareholders' Equity. 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 and $397 million as of Dec. 31, 2006 and June 30, 2006, respectively, was reclassified to Accumulated other comprehensive income.

CICA Section 3251, Equity, establishes standards for the presentation of equity and changes in equity during the reporting periods. The requirements under this Section have been effected in the presentation of the Consolidated Statements of Changes in Shareholders' Equity.

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.

Certain comparative figures have been restated to conform to the current periods' presentation. In particular, Canadian GAAP implemented EIC (Emerging Issues Committee) 162, Stock-Based Compensation for Employees Eligible to Retire Before the Vesting Date, which resulted in the acceleration of the recognition of compensation cost for stock-based awards based on employees' retirement eligibility at the date of the grant. This standard became effective for NOVA Chemicals in the fourth quarter of 2006 and was applied retroactively, with restatement of prior periods, as required by EIC 162.

(1) In the second quarter of 2007, the Canadian federal government
 reduced the general income tax rate from 19% to 18.5% effective
 January 1, 2011. As a result, future tax liabilities were reduced by
 $6 million. In the second quarter of 2006, future tax liabilities
 were reduced by $60 million as a result of the enactment of Canadian
 federal and Alberta provincial income tax rate reductions. The
 benefits that result from these periodic revisions are recorded as
 reductions in income tax expense in the applicable quarters.
(2) The tax benefits of certain costs have not been recorded due to
 uncertainty that tax benefits will be realized prior to the
 expiration of the loss carryforwards in the U.S.

7. Segmented Information

Refer to pages 104 and 105 of the Consolidated Financial Statements for the year ended Dec. 31, 2006 for the description of each segment and accounting policies for segment reporting. Beginning in the first quarter of 2007, NOVA Chemicals no longer allocates interest, taxes or corporate operating costs to the business segments. Prior period comparative amounts have been revised to reflect this change. Mark-to-market adjustments on NOVA Chemicals' open feedstock derivative positions are recorded as part of Corporate results until the positions are realized. Once realized, any income effects are recorded in business results.

The following tables provide information for each segment.

                                                     -------- --------
(1) Start-up Costs. Canadian GAAP provides that when an entity starts
     up a new facility, expenditures incurred during the pre-operating
     period may be deferred when certain criteria are met. Under U.S.
     GAAP, all costs (except interest on constructed assets)
     associated with start-up activities must be expensed as incurred.

(2) Derivative Instruments and Hedging Activities. CICA Section 3855
     harmonizes Canadian and U.S. GAAP by establishing standards for
     recognition and measurement of financial assets, liabilities and
     non-financial derivatives. CICA Section 3865 harmonizes Canadian
     GAAP with U.S. GAAP SFAS No. 133 by establishing standards for
     when and how hedge accounting may be applied and recorded. See
     Note 1 for further details. Certain differences that existed
     before the implementation of the above standards on Jan. 1, 2007,
     pertaining to the termination of interest rate swaps in 2002,
     continue to be reconciling items between Canadian GAAP and U.S.
     GAAP.

(3) Inventory Costing. Canadian GAAP allows fixed overhead costs
     associated with production activities to be expensed during the
     period whereas U.S. GAAP requires an allocation of fixed
     production overhead to inventory.

(4) Stock-Based Compensation. Under Canadian GAAP, the Employee
     Incentive Stock Option Plan is measured using a fair-value based
     method, while the Equity Appreciation Plan and the Restricted
     Stock Unit Plan classified as liability instruments and are
     marked-to-market based on intrinsic value. U.S. GAAP, SFAS No.
     123R, Share-Based Payment, effective Jan. 1, 2006, requires the
     share-based compensation transactions to be accounted for using a
     fair-value based method, such as the Black Scholes method. The
     fair value of awards classified as liability instruments must be
     remeasured subsequently at each reporting date through the
     settlement date. Changes in fair value during the requisite
     service period will be recognized as compensation cost over that
     period. The cumulative effect for the periods prior to Dec. 31,
     2005 of $5 million after-tax, has been charged to reinvested
     earnings (deficit) at Jan. 1, 2006.

(5) Pension Liability Adjustment. In 2006, for U.S. GAAP reporting,
     SFAS No. 158, Employers' Accounting for Defined Benefit Pension
     and Other Postretirement Plans - an amendment of SFAS Nos. 87,
     88, 106, and 132R, was effective. SFAS No. 158 requires an
     employer to recognize the overfunded or underfunded status of a
     defined benefit postretirement plan (other than a multi-employer
     plan) as an asset or liability in its statement of financial
     position and to recognize changes in that funded status in the
     year in which the changes occur through accumulated other
     comprehensive income. Accordingly, at Dec. 31, 2006, NOVA
     Chemicals recognized an additional pension and post-retirement
     liability of $124 million, resulting in a charge of $82 million
     (net of tax) to accumulated other comprehensive income. In 2006
     (prior to the adoption of SFAS No. 158), SFAS No. 87, Employer's
     Accounting for Pensions, was followed with respect to pension
     accounting, which required an employer to record an additional
     minimum liability (AML) if the unfunded accumulated benefit
     obligation exceeded the accrued pension liability or if there was
     a prepaid pension asset with respect to the plan. If an AML was
     recognized, an intangible asset, in an amount not exceeding the
     unrecognized prior service cost, was also recognized. The excess
     of the AML, over the intangible asset, if any, was charged to
     other comprehensive income, net of income tax effects.

(6) Income Taxes. Beginning Jan. 1, 2007, FIN 48, Accounting for
     Uncertainty in Income Taxes, became effective for U.S. GAAP
     reporting. FIN 48 clarifies the accounting for uncertainty in
     income taxes by prescribing a minimum recognition threshold that
     a tax position is required to meet before being recognized. An
     entity is required to recognize the best estimate of a tax
     position if that position is more likely than not to be sustained
     upon examination, based solely on the technical merits of the
     position. NOVA Chemicals adopted the provisions of FIN 48 on Jan.
     1, 2007 at which time a FIN 48 liability of $36 million was
     recognized by reclassifying $34 million out of deferred tax
     liability and $4 million from the current tax liability. This
     resulted in a $6 million increase in the liability for
     unrecognized tax benefits, and was accounted for as a reduction
     to the Jan. 1, 2007, U.S. GAAP balance in reinvested earnings.
     Since implementation of FIN 48 on Jan. 1, 2007, no further
     changes to the FIN 48 liability have been necessary. Also, it is
     NOVA Chemicals policy to recognize interest and penalties accrued
     related to unrecognized tax benefits in income tax expense. At
     June 30, 2007, NOVA Chemicals had approximately $6 million
     accrued for the payment of interest and penalties.

(7) Joint Ventures. NOVA Chemicals accounts for its interests in joint
     ventures using the Proportionate Consolidation method under
     Canadian GAAP. As permitted by specific U.S. SEC exemptions,
     adjustments to reflect equity accounting, as required under U.S.
     GAAP, have not been made. The equity method would not result in
     any changes in NOVA Chemicals' net income or shareholders'
     equity; however, all assets, liabilities, revenue, expenses, and
     most cash flow items would decrease when compared to the amounts
     that are presented using proportionate consolidation.

9. New Accounting Pronouncements

Canadian GAAP

CICA 1535, Capital Disclosures, applicable to interim and annual periods relating to fiscal years beginning on or after Oct. 1, 2007, specifies disclosures of (1) information about the entity's objectives, policies, and processes for managing capital structure; (2) quantitative data about what the entity regards as capital; and (3) whether the entity has complied with externally imposed capital requirements (for example bank covenants) and if it has not complied, the consequences of such non-compliance. NOVA Chemicals is currently evaluating the effect of adopting this standard.

CICA 3862, Financial Instruments - Disclosure and CICA 3863, Financial Instruments - Presentation, replace CICA 3861, Financial Instruments - Disclosure and Presentation. These new standards revise and enhance the disclosure requirements, and carry forward, substantially unchanged, the presentation requirements. These new standards emphasize the significance of financial instruments for the entity's financial position and performance, the nature and extent of risks arising from financial instruments, and how these risks are managed. These new standards are applicable to interim and annual periods relating to fiscal years beginning on or after Oct. 1, 2007. NOVA Chemicals is currently evaluating the effects of adopting these standards.

CICA 1400, General Standards of Financial Statement Presentation, was amended to include requirements to assess and disclose an entity's ability to continue as a going concern. The new requirements are effective for interim and annual financial statements relating to fiscal years beginning on or after Jan. 1, 2008. NOVA Chemicals is currently evaluating the effects of adopting the new requirements of this standard.

CICA 3031, Inventories, replaces CICA 3030, Inventories. The new standard is the Canadian equivalent to International Financial Reporting Standard IAS 2, Inventories. The main features of CICA 3031 are: (1) measurement of inventories at the lower of cost and net realizable value, with guidance on the determination of cost, including allocation of overheads and other costs to inventory; (2) cost of inventories of items that are not ordinarily interchangeable, and goods or services produced and segregated for specific projects, assigned by using a specific identification of their individual costs; (3) consistent use (by type of inventory with similar nature and use) of either first-in, first-out (FIFO) or weighted-average cost formula; (4) reversal of previous write-downs to net realizable value when there is a subsequent increase in value of inventories; and (5) possible classification of major spare parts and servicing stand-by equipment as property, plant and equipment (CICA 3061 - Property, Plant and Equipment, was amended to reflect this change). CICA 3031, applies to interim and annual financial statements relating to fiscal years beginning on or after Jan. 1, 2008. NOVA Chemicals is evaluating the effects of adopting this standard.

U.S. GAAP

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. NOVA Chemicals is currently evaluating the effects of adopting this standard.
