22. Sharebased payment (Continued)
Nokia calculates the fair value of stock options using the Black Scholes model. The fair value of the
stock options is estimated at the grant date using the following assumptions:
2008 2007 2006
Weighted average expected dividend yield ...... 3.20% 2.30% 2.08%
Weighted average expected volatility .......... 39.92% 25.24% 24.09%
Riskfree interest rate ....................... 3.15%  4.58% 3.79%  4.19% 2.86%  3.75%
Weighted average riskfree interest rate ........ 3.65% 4.09% 3.62%
Expected life (years) ........................ 3.55 3.59 3.60
Weighted average share price, EUR ............ 16.97 18.49 17.84
Expected term of stock options is estimated by observing general option holder behavior and actual
historical terms of Nokia stock option plans.
Expected volatility has been set by reference to the implied volatility of options available on Nokia
shares in the open market and in light of historical patterns of volatility.
Performance shares
The Group has granted performance shares under the global 2004, 2005, 2006, 2007 and 2008 plans,
each of which, including its terms and conditions, has been approved by the Board of Directors. A
valid authorization from the Annual General Meeting is required, when the plans are settled by using
the Nokia newly issued shares or treasury shares. The Group may also settle the plans by using cash
instead of shares.
The performance shares represent a commitment by the Group to deliver Nokia shares to employees
at a future point in time, subject to Nokia’s fulfillment of predefined performance criteria. No
performance shares will vest unless the Group’s performance reaches at least one of the threshold
levels measured by two independent, predefined performance criteria: the Group’s average annual
net sales growth for the performance period of the plan and earnings per share (“EPS”) at the end of
the performance period.
The 2004 and 2005 plans have a fouryear performance period with a twoyear interim measurement
period. The 2006, 2007 and 2008 plans have a threeyear performance period with no interim payout.
The shares vest after the respective interim measurement period and/or the performance period. The
shares will be delivered to the participants as soon as practicable after they vest. Until the Nokia
shares are delivered, the participants will not have any shareholder rights, such as voting or dividend
rights associated with the performance shares.
