Note 11 —
Share-Based Compensation
During
the three months ended November 30, 2011 and 2010, restricted
stock units (RSUs) totaling 1,043,736 shares at a
weighted-average per share price of $23.25 and 569,419 shares
at a weighted-average per share price of $30.56,
respectively, were awarded with vesting over three and
approximately four years, respectively. Of the RSUs awarded
during the three months ended November 30, 2011 and 2010,
688,411 shares and 269,511 shares, respectively, were
classified as liability awards at November 30, 2011, due to
the settlement of these awards in cash.
During
the three months ended November 30, 2011, there were no
options awarded. During the three months ended November 30,
2010, options for the purchase of 600,073 shares at a
weighted-average price of $30.56 per share, were awarded,
vesting over approximately four years. The contractual lives
of the awards during the three months ended November 30,
2010, are consistent with those of prior years. There were no
significant changes in the assumptions or estimates used in
the valuation of options subsequent to our year-end, August
31, 2011.
During
the three months ended November 30, 2011 and 2010, options
were exercised for the purchase of 30,040 shares at a
weighted-average exercise price of $17.28 per share and
110,840 shares at a weighted-average exercise price of $22.23
per share, respectively.
There
were no stock appreciation rights (SARs) awarded during the
three months ended November 30, 2011. During the three months
ended November 30, 2010, we awarded 358,751 SARs at a
weighted average price of $30.56 per share, vesting over
approximately four years. The Binomial valuation method was
used to re-measure the fair value of the SARs at November 30,
2011. The SARs are classified as liability awards at November
30, 2011, due to the settlement of these awards in
cash.
During
the three months ended November 30, 2011, we awarded
11,661,500 performance cash units (PCUs), at a weighted
average fair value of $1.13 per unit, vesting over
approximately three years. The PCUs represent the right to
receive $1 for each earned PCU if specified performance goals
are met over the three-year performance period. The PCU
recipients may earn between 0% and 200% of their individual
target award amount depending on the level of performance
achieved. The fair value of PCUs was estimated at the grant
date based on the probability of satisfying the performance
goals associated with the PCUs using a Monte Carlo simulation
model. The PCUs are classified as liability awards at
November 30, 2011, due to the settlement of these awards in
cash.
Compensation
cost for liability-classified awards is re-measured at each
reporting period and is recognized as an expense over the
requisite service period.
