Terminal Learning Objective • Action: Recommend investment course of action based on NPV calculation • Condition: You are a cost advisor technician with access to all regulations/course handouts, and awareness of Operational Environment (OE)/Contemporary Operational Environment (COE) variables and actors • Standard: with at least 80% accuracy • Identify and enter relevant report data to solve Net Present Value equations using macro enabled templates and make appropriate recommendation © Dale R. Geiger 2011 3
What is Net Present Value • “Net” refers to the result of combining multiple values • Net Pay combines wages earned (+) and payroll tax deductions (-) • Net Change in Financial Position combines Revenues (+) and Costs (-) • Net Present Value (NPV) refers to the combination of multiple discounted cash flows • A positive NPV means that the PV of the cash inflows outweighs the PV of the outflows © Dale R. Geiger 2011 4
Multiple Cash Flows • Today is Rebecca’s 16 th birthday. Her inheritance is held in trust and will be paid in the following installments: • • $20, 000 on her 21 st birthday $40, 000 on her 30 th birthday $60, 000 on her 40 th birthday $100, 000 on her 50 th birthday • Assume a discount rate of 8% • Task: Calculate the NPV of Rebecca’s inheritance © Dale R. Geiger 2011 5

Questions to Think About • What would happen to the Present Value of Rebecca’s inheritance if she assumed a 6% discount rate? A 12% discount rate? • Rebecca has found a company that will pay her $40, 000 cash now if she signs over her inheritance. What should she do? • What factors should she consider? © Dale R.

Geiger 2011 22
Algebra of an Annuity • Essentially the NPV formula is: (Cash Flow 1 * PV Factor 1) + (Cash Flow 2 * PV Factor 2) and so on…. • If the cash flows are equal, they will factor out and this becomes: Cash Flow * (PV Factor 1 + PV Factor 2) © Dale R. Geiger 2011 23
Annuity = Equal Cash Flows Year Cash Flow 1 -20, 000 2 -20, 000 3 -20, 000 4 -20, 000 * * PV Factor 4% + 0. 962 + 0. 925 + 0. 889 + 0. 855 = 3. 630 = = PV of Cash Flow -19, 231 -18, 491 -17, 780 -17, 096 • The sum of the four factors is called the Annuity Factor • The Annuity Factor can be found on the PV Annuity Table © Dale R. Geiger 2011 24
Using the PV Annuity Table The PV Annuity factor on the table is equal to the sum of the PV factors for a single cash flow for Year 1 through Year 4 © Dale R. Geiger 2011 25

Net Present Value • Reengineering a business process in your unit will cost $1 million now but will save an estimated $400, 000 per year for the next three years. • Assuming a discount rate of 10%, what is the NPV of this course of action? © Dale R. Geiger 2011 30

Using the PV Annuity Table -Initial Investment +( Cash Flow *Annuity Factor) = NPV -1, 000 +( 400, 000*2. 487) = -5, 200 © Dale R. Geiger 2011 32
Should we proceed with Reengineering? • NPV is negative, so we should not proceed • The present value of the benefits to be received in the future is less than the initial investment • What if the discount rate is 8%? -Initial Investment + Cash Flow (Savings) *Annuity Factor = NPV -1, 000 + 400, 000*2. 577 = 30, 800 © Dale R.
