Basic and diluted earnings per common share and the average number of shares of common stock outstanding in the first and second quarter of 2011 were retrospectively restated adjusting the number of shares of Home & Security common stock using the number of shares of common stock outstanding as of September 27, 2011. In periods prior to the Separation, the same number of shares was used to calculate basic and diluted earnings per share since no Home & Security stock-based awards were outstanding prior to the Separation.
