Provides for the following items if their inclusion is dilutive: (i) the effect of the issuance of 18 million shares of common stock reserved for the Settlement agreement as defined and (ii) the effect of non-vested restricted stock, restricted stock units and contingently issuable shares using the treasury stock method. In calculating diluted net (loss) earnings per common share for 2012, our diluted weighted average number of common shares outstanding excludes the effect of the items mentioned above as the effect was anti-dilutive.

During the fourth quarter of 2014, we changed the method of valuing our inventories that used the LIFO method to the FIFO method, so that all of our inventories are now valued at FIFO. As a result of this accounting change, net earnings (loss) available to common stockholders, basic earnings per share – continuing operations and diluted earnings per share – continuing operations, among other accounts, have been retrospectively changed. Refer to Note 2, “Summary of Significant Accounting Policies – Inventories,” for a discussion of our change in accounting policy.
