Internal rate of return method in analyzing capital expenditure:

Present value of expenditure = $149,630

Present of cash inflows annuity = $149,630 (using 20% discount rate and present value annuity factor of 3.3251 x $45,000)

NPV = $0 (PV of cash outflow - PV of cash inflow)

Therefore, the IRR = 20%

Explanation:

a) Data and Calculations:

Investment cost = $149,630

Annual net cash flows = $45,000

Investment period = 6 years

Annuity of future cash flows = 3.3251

b) Testerman’s IRR (Internal Rate of Return) is a capital budgeting and analysis tool which determines the discount rate that makes the present value of future inflows equal to the present value of outflows from a project.  This IRR helps the managers to determine the projects that add value and are worth undertaking.  IRR is based on assumptions.  Similar projects with the same IRR will differ in returns due to the differences in timing and the size of the cash, the amount of debts and equity used  to generate the returns, and the assumption of a constant reinvestment may which IRR makes.
