Business Combinations

On March 22, 1999, Lumonics Inc. and General Scanning, Inc. (General Scanning) completed a merger of equals to form the Company. Under Canadian GAAP, the merger was accounted for using the pooling of interests method and the consolidated financial statements reflect the combined historical carrying values of the assets, liabilities, stockholders’ equity and the historical operating results of the two predecessor companies.

Under U.S. GAAP, the merger has been accounted for as a purchase transaction. The purchase price, based on the fair value of General Scanning shares purchased, is allocated in the consolidated financial statements to acquired net identifiable General Scanning assets. Property, plant and equipment and acquired intangible assets were recorded at their estimated fair values at the time of the 1999 acquisition and are being amortized over their useful life.

The Canadian GAAP loss before income taxes was lower than the corresponding U.S. GAAP amounts due to amortization of lower net book values of property, plant and equipment and acquired intangible assets resulting from different methods of accounting for the business combination. The different net book values resulted in a lower depreciation and amortization expense under Canadian GAAP by $0.9 million and $0.7 million for the three months ended June 27, 2003 and June 28, 2002, respectively. For the six months ended June 27, 2003 and June 28, 2002, the impact of this difference was to decrease depreciation and amortization expense under Canadian GAAP by $1.8 million and $1.6 million, respectively.

Under Canadian GAAP, global investment tax credits are required to be netted against research and development expense. Under U.S. GAAP, these amounts are included in the income tax provision. For the three and six months ended June 27, 2003, there were no investment tax credits recorded, as there was doubt as to whether their value would be realized. For the three and six months ended June 28, 2002, there were no global investment tax credits recorded. Therefore, there was no impact on the net loss before income taxes for either the three months and six months ended June 27, 2003 or the three months and six months ended June 28, 2002.

For the three and six months ended June 27, 2003, no tax benefit was recorded under either Canadian GAAP or U.S. GAAP, as the Company increased valuation allowances against its tax assets. The Canadian GAAP income tax benefit for the three and six months ended June 28, 2002 does not reflect any income tax recovery for the depreciation and amortization and investment tax credits presented only under U.S. GAAP.
