To calculate the price per £100 nominal, we need to find the present value of the bond's cash flows, which include the coupon payments and the redemption value, discounted at the net real yield.<br /><br />Given information:<br />- Coupon rate: 6% per annum, paid half-yearly<br />- Redemption value: £105 per £100 nominal<br />- Income tax: 20%<br />- Capital gains tax: 25%<br />- Net real yield: 5% per annum<br /><br />Step 1: Calculate the after-tax coupon payment.<br />After-tax coupon payment = Coupon payment * (1 - Income tax rate)<br />After-tax coupon payment = (£6 / 2) * (1 - 0.20) = £2.40 per half-year<br /><br />Step 2: Calculate the present value of the coupon payments.<br />Since the coupons are paid half-yearly, we need to discount the coupon payments semi-annually.<br />Discount rate = 1 + Net real yield / 2 = 1 + 0.05 / 2 = 1.025<br />Present value of coupon payments = £2.40 * (1 - (1 + 0.025)^(-20)) / 0.025 = £31.11<br /><br />Step 3: Calculate the present value of the redemption value.<br />Present value of redemption value = £105 / (1 + 0.025)^20 = £46.88<br /><br />Step 4: Calculate the price per £100 nominal.<br />Price per £100 nominal = Present value of coupon payments + Present value of redemption value<br />Price per £100 nominal = £31.11 + £46.88 = £77.99<br /><br />Therefore, the price per £100 nominal if the investor is to obtain a net real yield of 5% per annum is approximately £77.99.
