"We had a good sales performance from a price and volumes standpoint. However these benefits were more than offset by a seasonally high level of scheduled maintenance in our mills," said John D. Williams, President and Chief Executive Officer. On paper demand trends, Mr. Williams added, "Domtar paper shipments continue to trend better than forecast with healthy export volumes and good demand in our packaging paper grades. We continue to be successful in servicing our customers while keeping paper inventories tight."

QUARTERLY REVIEW

Operating income before items was $165million in the second quarter of 2011 compared to an operating income before items1 of $218million in the first quarter of 2011. Depreciation and amortization totaled $95 million in the second quarter of 2011. When compared to the first quarter of 2011, paper shipments decreased 1% while pulp shipments decreased 4%. The shipments-to-production ratio for paper was 101% in the second quarter of 2011, compared to 102% in the first quarter of 2011. Paper inventories declined by 11,000 tons while pulp inventories decreased by 8,000 metric tons as at the end of June, compared to March levels. Operating loss before items1 of ArivaTM, our Paper Merchants segment, remains under pressure and declined by $2 million when compared to the first quarter of 2011. This is mostly due to lower deliveries resulting from difficult market conditions in the paper merchants channel and to the sale of a business unit at the end of the first quarter of 2011.

The decrease in operating income before items in the second quarter of 2011 was the result of higher maintenance costs, lower pulp and paper shipments, higher freight costs and higher unit costs for wood fiber and chemicals as well as the negative impact of a stronger Canadian dollar. These factors were partially offset by higher average selling prices in pulp and paper.

LIQUIDITY AND CAPITAL

Cash flow provided from operating activities amounted to $306 million including a source of cash resulting from a reduction in working capital of $77 million. Capital expenditures amounted to $20 million resulting in free cash flow3 of $286 million in the second quarter of 2011.

Domtar returned a total of $175 million to its shareholders through a combination of dividend and stock buyback in the second quarter of 2011. Under its stock repurchase program, Domtar repurchased 1,682,047 shares of common stock during the second quarter and a total of 3,210,051 shares of common stock at an average price of $86.88 per share since the implementation of the program.

On June 23, 2011, the Company entered into a new unsecured $600 million credit agreement maturing in June 2015 to replace the existing secured revolving credit facility of $750 million that was scheduled to mature in March of 2012.

OUTLOOK

Looking into the second half of 2011, the benefits from announced price increases for business papers and lower costs stemming from maintenance in the mills are expected to favorably impact financial results. While selling prices for pulp are likely to decline on average compared to the first half of the year, uncoated freesheet paper shipments for 2011 are expected to remain steady when compared to 2010. Inflation pressures due to recent rises in commodity prices are expected to continue throughout the second half of the year.
