Reconciliation to United States GAAP

Years ended October 4, 2009, October 5, 2008 and September 30, 2007

(Tabular amounts in thousands or thousands of US dollars, except per share amounts)

(a)	Consolidated statements of earnings (continued):
	(i)	Adoption of CICA Handbook Section 3064
		In February 2008, Canada’s Accounting Standards Board (AcSB) issued Canadian Institute of Chartered Accountants (CICA) issued Handbook Section 3064, Goodwill and Intangible Assets, replacing Section 3062, Goodwill and Other Intangible Assets, and Section 3450, Research and Development Costs. Section 3064 establishes revised standards for the recognition, measurement, presentation and disclosure of goodwill and intangible assets. The new Section also provides guidance for the treatment of preproduction and start-up costs and requires that these costs be expensed as incurred. Prior to the adoption of Section 3064, the Company deferred and amortized plant start-up costs on a straight-line basis over two years under Canadian GAAP. This Section applies to annual financial statements relating to the Company’s fiscal year beginning on October 6, 2008 and has been adopted on a retrospective basis effective from the first quarter of fiscal 2009. The impact of adopting this Section, on a retrospective basis, was an increase of $1.8 million (increase of $0.01 per share on a basic and diluted basis) and a decrease of $1.0 million (decrease of $0.01 per share on a basic and diluted basis) in net earnings under Canadian GAAP for the years ended October 5, 2008 and September 30, 2007, respectively. The adoption of this Section also resulted in a decrease of $2.5 million in shareholders’ equity at October 1, 2007 under Canadian GAAP. United States GAAP requires preproduction and start-up costs to be expensed as incurred. The adoption of this Section on a retroactive basis eliminates the difference that existed for the accounting of start-up costs between Canadian GAAP and United States GAAP.
	(ii)	Swap revenue
		Under Canadian GAAP, the Company was using hedge accounting for certain derivative instruments. The gain realized on cancellation of a cross-currency interest rate swap arrangement was deferred, and was being amortized over the term of the related debt. Under United States GAAP, the Company had not designated the derivative instrument in a hedging relationship and, consequently, upon cancellation of the instrument, the Company recognized the gain immediately into earnings.
