[1] | Amounts reflect the retrospective impact of reporting the marine, cargo systems and cargo container businesses as discontinued operations. See Note 18.
[2] | During the third quarter of 2010, the Company determined that an out-of-period adjustment associated with tax returns filed and tax audit conclusions was required, which reduced income tax expense by approximately $5.7 million. The Company has determined that this was not material on a quantitative or qualitative basis to the prior period financial statements.
[3] | 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.
