Employee Sharesave grants, under the BT Group Employee Sharesave and the BT Group International Employee Sharesave option plans,
are valued using a Binomial option pricing model. Awards under the ISP are valued using Monte Carlo simulations. TSRs were generated for
BT and the comparator group at the end of the three year performance period, using each company’s volatility and dividend yield, as well
as the cross correlation between pairs of stocks.
Volatility has been determined by reference to BT’s historical volatility which is expected to reflect the BT share price in the future. An
expected life of three months after vesting date is assumed for Employee Sharesave options and for all other awards the expected life is
equal to the vesting period. The risk free interest rate is based on the UK gilt curve in effect at the time of the grant, for the expected life of
the option or award.
The fair values for the RSP and DBP were determined using the market price of the shares at the date of grant. The weighted average
share price for RSP awards granted in 2010 was 104p (2009: 151p, 2008: 310p). The weighted average share price for DBP awards
granted in 2010 was 131p (2009: 203p, 2008: 319p).
