A bond with a nominal face value of
$100; 000 is redeemable by two payments, one in 5 years time and
the other in 10 years time. The payment in 5 years time is for a
nominal amount of $40; 000 and in 10 years time for a nominal
amount of $60; 000. Redemption payments are payable at $105 per
$100 nominal face value. Coupons are paid on the bond at 6% p.a
semi-annually based on the nominal amount outstanding. Tax is
paid on the coupons at a rate of 30% and tax is paid on capital
gains at a rate of 15%. Capital losses are assumed to be offset
against other capital gains of the investor.
