[1] The per-share computation for the year is a separate, annual calculation. Accordingly, the sum of the quarterly per-share amounts does not necessarily equal the annual per-share amount.

[2] Dilutive securities are not included in the computation of diluted earnings per share when a company is in a loss position. As such, the numerator and the denominator used in computing both basic and diluted net loss per share for 2011 are the same. Diluted weighted average shares outstanding were 367.6 million in 2011.
