In this class, we will stick primarily to using the annual rates. Source: Figure 7.3 from Davis, et al. 2001 Forest Management, p. 341 Solution a. As seen from the table, Present value of perpetual periodic CF is = P/[(1+i)^t - 1]= 50000/[1.07^45 - 1] = 50000/(21.002 - 1) = $2,499.69 b. Present value of a perpetual $100 tax = P/i = 100/0.07 = $1,428.57 Present value of the cash flow = 2,499.69 - 1,428.57 = $1,071.12 c. AS the asking price of the land is $1000 and is less than the NPV of $1,071.12 you should buy it..
