[1] The computation of basic and diluted earnings per share assumes that the number of shares outstanding for the first three quarters of fiscal 2013 and each quarter in fiscal 2012 was equal to the number of ordinary shares of Mallinckrodt outstanding on June 28, 2013, immediately following the distribution of one ordinary share of Mallinckrodt for every eight ordinary shares of Covidien.

[2] Quarterly and annual computations are prepared independently. Therefore, the sum of each quarter may not necessarily total the fiscal period amounts noted elsewhere within this prospectus.
