NET EARNINGS PER SHARE

NET EARNINGS PER SHARE

Our basic and diluted earnings per share attributable to Weyerhaeuser shareholders were:

• $0.26 during first quarter 2013; and

• $0.08 during first quarter 2012.

Basic earnings per share is net earnings divided by the weighted average number of our outstanding common shares, including stock equivalent units where there is no circumstance under which those shares would not be issued.

Diluted earnings per share is net earnings divided by the sum of the:

• weighted average number of our outstanding common shares and

• the effect of our outstanding dilutive potential common shares.

Dilutive potential common shares can include:

• outstanding stock options,

• restricted stock units and

• performance share units.

We use the treasury stock method to calculate the effect of our outstanding dilutive potential common shares. Share-based payment awards that are contingently issuable upon the achievement of specified performance or market conditions are included in our diluted earnings per share calculation in the period in which the conditions are satisfied.

SHARES EXCLUDED FROM DILUTIVE EFFECT

The following shares were not included in the computation of diluted earnings per share because they were either antidilutive or the required performance or market conditions were not met. Some or all of these shares may be dilutive potential common shares in future periods.
