Summary financial information
 
The summary income statement, balance sheet, cash flow and key figures of the Group presented below in accordance with Finnish Accounting Standards ("FAS") have been derived from the audited consolidated financial statements of the Company, prepared in accordance with FAS, for the financial years ended December 31, 2004 and December 31, 2003, unless otherwise stated below. As of January 1, 2005, the Company adopted International Financial Reporting Standards as adopted by the European Union ("IFRS") as the basis for preparing its consolidated financial statements. Audited consolidated financial statements for the year ended December 31, 2005, together with the unaudited comparative period ended December 31, 2004, have been prepared in accordance with IFRS, unless otherwise stated below. The summary IFRS financial information presented below is derived from the consolidated IFRS financial statement and is not comparable to the summary financial information presented in accordance with FAS. FAS differs from IFRS in certain material respects.
 
 
 

(1) The figures have been derived from the audited consolidated financial statements unless otherwise stated.
(2) Expenses: Expenses include the following items from the 2003 and 2004 income statements prepared in accordance with FAS: Change in inventories for finished goods, Production for own use, Materials and services, Employee benefit expenses and Other operating expenses. Expenses include the following items from the 2005 income statements prepared in accordance with IFRS: Change in inventories of finished goods and work in process, Production for own use, Materials and supplies, Employee benefit expenses and Other operating expenses.
(3) Share of the profit of associated companies: The Company has reported the share of associated companies' profit before operating profit under FAS and after operating profit under IFRS.
(4) Amortization of goodwill, FAS: Under FAS goodwill is amortized annually, whereas under IFRS goodwill is periodically tested for potential impairment. As a result, goodwill amortization under FAS is presented as a separate line item for the financial years 2003 and 2004.
(5) The change in notes receivable and short-term investments is included in net cash flow from financing under FAS and in net cash from investing activities under IFRS.
(6) The 2003 and 2004 figures (FAS) have been derived from the accounting system of the Company and are unaudited.
 
 
Key figures for the Group
 
 

(1) Figures have been derived from the audited consolidated financial statements unless otherwise stated.
(2) Calculation of key figures; As a result of the transition to IFRS, the terminology in the formulas used to calculate the key ratios were adjusted. Although the content and the technical calculation principles of these key figures remained unchanged, the transition to IFRS reporting caused adjustments to the financial position, operating result and cash flows of the Group. The effect of the adoption of IFRS reporting and related bridge calculations are presented in the notes to the Company's financial statements for 2005. With the exception of earnings per share, these key figures are not measures of financial performance under IFRS.
(3) EBITDA is not a measure of financial performance under FAS or IFRS and is unaudited. EBITDA is equivalent to operating profit plus depreciation of tangible assets and amortization and impairment of goodwill and other intangible assets. Under FAS, the Company has reported the share of the profit of associated companies in EBITDA and the positive impact amounted to EUR 3.4 million in 2003 and EUR 2.8 million in 2004. However, under IFRS the Company has reported the share of the profit of associated companies after EBITDA. The Company presents EBITDA because it considers it an important supplemental measure of its operating performance. Management believes that EBITDA is a standard measure commonly reported and widely used by analysts, investors and other interested parties in the industry.
(4) Diluted earnings per share and average number of shares, diluted; Average number of shares, diluted, is weighted average of the number of outstanding shares adjusted to give effect to the issue of potential new ordinary shares.
(5) Average number of personnel; In the financial statements for 2004, the average number of personnel was calculated as an average of the number of personnel at the beginning of the year and at the end of the year, whereas in the financial statements for 2005 the number has been calculated as an average of the quarters of the financial year.

* Ahlstrom's Cores and Board  operations were transferred to Sonoco-Alcore Group in 2004. The figures in the table have been adjusted to (i) reflect the divestment of Ahlstrom's Cores and Board operations as if such divestment had occurred on January 1, 2003, and (ii) remove the effect of other non-recurring items.
(1) FAS Adjusted and IFRS Adjusted mean adjusted figures derived either from FAS or IFRS reporting and based on the same basic information used for the preparation of audited consolidated financial statements. The most significant adjustment is the elimination of the divested Cores and Board operations and non-recurring items, which are based on management's assessment and are not defined under FAS or IFRS.
(2) Adjustments in net sales relate to the divested Cores and Board operations, EUR 97.8 million in 2003 and EUR 77.9 million in 2004.
(3) EBITDA is not a measure of financial performance under FAS or IFRS. EBITDA is equivalent to operating profit plus depreciation of tangible assets and amortization and impairment of goodwill and other intangible assets. Under FAS the Company has reported share of profit of associated companies in EBITDA and the positive impact amounted to EUR 3.4 million in 2003 and EUR 2.8 million in 2004. However, under IFRS the Company has reported share of profit of associated companies after EBITDA. EBITDA is used in the Company's business segments to provide additional financial information. Management believes that EBITDA is a standard measure commonly reported and widely used by analysts, investors and other interested parties in the industry.
(4) The Cores and Board adjustment reduces Capital expenditures and acquisitions by EUR 3.4 million in 2003 and EUR 2.0 million in 2004.
(5) The Cores and Board adjustment reduces Capital employed by EUR 55.5 million in 2003.
