【答案解析】This is essentially a two-stage DDM problem. Discounting all future cash flows, we get:

Note that the constant growth formula can be applied to dividend 8 because it will grow at a constant rate (5%) forever. It is preferable to do this with the right keystrokes on the calculator but it is a bit tricky. Since the first non-zero cash flow occurs in year 5, we have to communicate this information to the calculator correctly to get the indicated solution. Using the CF function the sequence of keystrokes would be : CF
0=0; CF
1=0, F
1=4; CF
2=1.00; CF
3=1.25; CF
4=1.5625; CF
5=40.6471; I=10.3; CPT NPV=$20.647. When we input the first dividend as CF
2=1.00, we are telling the calculator that this is really received in the fifth year and it is then discounted correctly. Note that CF5 is made up of two components-the dividend that is paid in year 8=1.25
3=1.93125 plus the present value of the constantly growing ( at 5% ) perpetuity =
