(b) | Based on our internal analysis concluded as part of our annual assessment, all previously capitalized costs related to the American Centrifuge project were expensed as of December 31, 2012. Capitalization of expenditures related to the American Centrifuge project has ceased until commercial deployment resumes. See Notes 8 and 20 for further details related to the American Centrifuge project.
The calculation of net income per share and average number of shares outstanding on a dilutive basis for the years ended December 31, 2013, 2012 and 2011 is provided in Note 18. No dilutive effect is recognized in periods in which a net loss has occurred or in which the assumed conversion effect of convertible securities is antidilutive.
