[1] Amounts reflect the retrospective impact of reporting the orthopedic business as discontinued operations. See Note 19.

[2] The Company identified $0.1 million and $0.4 million, net of tax, of environmental costs related to discontinued operations that were erroneously reported in continuing operations during the first and second quarters of 2011, respectively, which did not change diluted earnings per share for the first quarter and increased diluted earnings per share by $0.01 for the second quarter. The Company has classified these environmental costs as income from discontinued operations. Management has determined that the impact of this error was not material on a quantitative or qualitative basis to the financial statements for the first and second quarters of fiscal 2011.

[3] Amounts include a pretax goodwill impairment charge of $332.1 million, or $315.1 million net of tax. See Note 5.

[4] Segment operating profit includes a segment's net revenues from external customers reduced by its cost of goods sold, selling, general and administrative expenses, research and development expenses and an allocation of corporate expenses. Segment operating profit excludes goodwill impairment charges, restructuring and impairment charges, net (gain) loss on sales of businesses and assets, interest income and expense, loss on extinguishment of debt and taxes on income.
