Stock-Based Compensation |
Note 8 – Stock-Based Compensation
Equity Compensation Awards
Stock Options
Stock
options have been granted under various equity compensation
plans. While we may grant options to employees that
become exercisable at different times or within different periods,
we have generally granted options to employees that vest and become
exercisable in one-third increments on the 2nd,
3rd
and 4th
anniversaries, of the grant dates. The maximum
contractual term for all options is normally ten
years.
We
use the Black-Scholes option-pricing model to calculate the
grant-date fair value of an option. The fair value of
options granted during the three and six month periods ended June
30, 2012 and 2011 were calculated using the following
weighted-average assumptions:
Expected volatility – In determining expected
volatility, we have considered a number of factors, including
historical volatility and implied volatility.
Expected term – We use historical employee exercise
data to estimate the expected term assumption for the Black-Scholes
valuation.
Risk-free interest rate – We use the yield on
zero-coupon U.S. Treasury securities for a period commensurate with
the expected term assumption as its risk-free interest
rate.
Expected dividend yield – We do not currently pay
dividends on our common stock; therefore, a dividend yield of 0%
was used in the Black-Scholes model.
In
most cases, we recognize expense using the straight-line
attribution method for stock option grants. The amount
of stock-based compensation recognized during a period is based on
the value of the portion of the awards that are ultimately expected
to vest. Forfeitures are required to be estimated at the
time of grant and revised, if necessary, in subsequent periods if
actual forfeitures differ from those estimates. The term
“forfeitures” is distinct from
“cancellations” or “expirations” and
represents only the unvested portion of the surrendered
option. We currently expect, based on an analysis of our
historical forfeitures, an annual forfeiture rate of approximately
3% and applied that rate to the grants issued. This
assumption will be reviewed periodically and the rate will be
adjusted as necessary based on these
reviews. Ultimately, the actual expense recognized over
the vesting period will only be for those options that
vest.
During
the three and six month periods ended June 30, 2012, we recognized
approximately $0.6 million and $1.3 million of stock option
compensation expense, respectively. During the three and six month
periods ended June 30, 2011, we recognized approximately $0.8
million and $1.3 million of stock option compensation expense,
respectively.
A
summary of the activity under our stock option plans as of June 30,
2012 and changes during the three and six month periods then ended,
is presented below:
*
In addition to the vested options, we expect a portion of the
unvested options to vest at some point in the
future. Options expected to vest are calculated by
applying an estimated forfeiture rate to the unvested
options.
During
the six month period ended June 30, 2012, the total intrinsic value
of options exercised (i.e., the difference between the market price
at time of exercise and the price paid by the individual to
exercise the options) was $1.1 million, and the total amount of
cash received from the exercise of these options was $3.5
million.
Performance-Based Restricted Stock
In
2006, we began granting performance-based restricted stock grants
to certain key executives. These grants cliff vest at
the end of the three-year measurement period, except for grants to
those individuals who are retirement eligible during the grant
period as such awards are subject to accelerated vesting as the
grant is earned over the course of the vesting period (i.e. a
pro-rata payout occurs based on the retirement
date). Participants are eligible to be awarded shares
ranging from 0% to 200% of the original award amount, based on
certain defined performance measures. Compensation expense is
recognized ratably over the vesting period, unless the employee has
an accelerated vesting schedule. Additionally,
compensation expense is increased or decreased based on changes in
the estimated pay out percentages each quarter. The 2009 grant,
which vested as of December 31, 2011, met the performance criteria
and was paid out at 97.4% of target.
During
the three and six month periods ended June 30, 2012, due to
reductions in the estimated payout percentages of outstanding
grants, we recognized income for performance-based restricted stock
awards of approximately $0.5 million and $0.4 million,
respectively. During the three and six month periods
ended June 30, 2011, we recognized expense for performance-based
restricted stock awards of approximately $0.9 million and $1.1
million, respectively.
Time-Based Restricted Stock
In
2011, we began granting time-based restricted stock awards to
certain key executives and other key members of the Company’s
management team. Time-based restricted stock grants
typically cliff vest at the end of the three-year vesting period,
and we recognize compensation expense on these awards ratably over
the vesting period. The fair value of the award is
determined based on the market value of the underlying stock price
at the grant date.
During
the three and six month periods ended June 30, 2012, we recognized
compensation expense for time-based restricted stock awards of
approximately $0.4 million and $0.9 million,
respectively. During the three and six month periods
ended June 30, 2011, we recognized expense for time-based
restricted stock awards of approximately $0.2 million of during
each period.
Deferred Stock Units
We
grant deferred stock units to non-management
directors. These awards are fully vested on the date of
grant and the related shares are generally issued on the
13th
month anniversary of the grant date unless the individual elects to
defer the receipt of these shares. Each deferred stock
unit results in the issuance of one share of Rogers’
stock. The grant of deferred stock units is typically
done annually in the second quarter of each year.
For
each of the three and six month periods ended June 30, 2012 and
2011, we recognized compensation expense of $0.7 million related to
deferred stock units. There was no expense associated
with these grants in the first quarter of either
year.
Employee Stock Purchase Plan
We
have an employee stock purchase plan (ESPP) that allows eligible
employees to purchase, through payroll deductions, shares of our
common stock at a discount to fair market value. The
ESPP has two six month offering periods each year, the first
beginning in January and ending in June and the second beginning in
July and ending in December. The ESPP contains a
look-back feature that allows the employee to acquire stock at a
15% discount from the underlying market price at the beginning or
end of the applicable period, whichever is lower. We
recognize compensation expense on this plan ratably over the
offering period based on the fair value of the anticipated number
of shares that will be issued at the end of each offering
period. Compensation expense is adjusted at the end of
each offering period for the actual number of shares
issued. Fair value is determined based on two factors:
(i) the 15% discount amount on the underlying stock’s market
value on the first day of the applicable offering period, and (ii)
the fair value of the look-back feature determined by using the
Black-Scholes model. We recognized approximately $0.1
million of compensation expense associated with the plan for each
of the three month periods ended June 30, 2012 and, 2011, and
approximately $0.2 million of compensation expense associated with
the six month periods ended June 30, 2012 and 2011.
