(1) The assumed exercise of stock-based compensation awards for this period was not considered in the calculation of diluted earnings (loss) per share because the impact would have been anti-dilutive.

(2) Includes charges related to non-cash interest associated with amortization of a debt discount of $1.5 million and $1.6 million for the third and fourth quarter, respectively.

(3) We calculated earnings per share for each of the quarters based on the weighted average number of shares and dilutive securities outstanding for each period.  Accordingly, the sum of the quarters may not necessarily be equal to the full year income per share.

(4) Includes charges related to one-time termination benefits associated with capacity realignment of $1.8 million.
