Night-Lights and Nearsightedness (A) Net Present Value (NPV) / MBA Resources

Introduction to Net Present Value (NPV) - What is Net Present Value (NPV) ? How it impacts financial decisions regarding project management?

NPV solution for Night-Lights and Nearsightedness (A) case study

At Oak Spring University, we provide corporate level professional Net Present Value (NPV) case study solution. Night-Lights and Nearsightedness (A) case study is a Harvard Business School (HBR) case study written by Phillip E. Pfeifer, Karla Zadnik. The Night-Lights and Nearsightedness (A) (referred as “Myopia Nearsightedness” from here on) case study provides evaluation & decision scenario in field of Innovation & Entrepreneurship. It also touches upon business topics such as - Value proposition, .

The net present value (NPV) of an investment proposal is the present value of the proposal’s net cash flows less the proposal’s initial cash outflow. If a project’s NPV is greater than or equal to zero, the project should be accepted.

NPV = Present Value of Future Cash Flows LESS Project’s Initial Investment

Case Description of Night-Lights and Nearsightedness (A) Case Study

Researchers at the University of Pennsylvania were interested in whether exposure to light early in life might affect eye growth and lead to an increased risk of myopia (nearsightedness). Eyes grew rapidly after birth, but myopia usually did not develop until later in life and arose from excessive postnatal eye growth. They knew that the duration of daily light had been shown to increase eye growth in chicks and wondered whether the same might be true for humans. The results startled researchers and might explain the increase in myopia rates over the last two centuries. The B case gives the results of a follow-on study conducted by the Ohio State University.

In isolation the NPV number doesn't mean much but put in right context then it is one of the best method to evaluate project returns. In this article we will cover -

Capital Budgeting Approaches

Methods of Capital Budgeting

There are four types of capital budgeting techniques that are widely used in the corporate world –

1. Payback Period
2. Profitability Index
3. Net Present Value
4. Internal Rate of Return

Apart from the Payback period method which is an additive method, rest of the methods are based on Discounted Cash Flow technique. Even though cash flow can be calculated based on the nature of the project, for the simplicity of the article we are assuming that all the expected cash flows are realized at the end of the year.

Discounted Cash Flow approaches provide a more objective basis for evaluating and selecting investment projects. They take into consideration both –

1. Timing of the expected cash flows – stockholders of Myopia Nearsightedness have higher preference for cash returns over 4-5 years rather than 10-15 years given the nature of the volatility in the industry.
2. Magnitude of both incoming and outgoing cash flows – Projects can be capital intensive, time intensive, or both. Myopia Nearsightedness shareholders have preference for diversified projects investment rather than prospective high income from a single capital intensive project.

Formula and Steps to Calculate Net Present Value (NPV) of Night-Lights and Nearsightedness (A)

NPV = Net Cash In Flowt1 / (1+r)t1 + Net Cash In Flowt2 / (1+r)t2 + … Net Cash In Flowtn / (1+r)tn
Less Net Cash Out Flowt0 / (1+r)t0

Where t = time period, in this case year 1, year 2 and so on.
r = discount rate or return that could be earned using other safe proposition such as fixed deposit or treasury bond rate. Net Cash In Flow – What the firm will get each year.
Net Cash Out Flow – What the firm needs to invest initially in the project.

Step 1 – Understand the nature of the project and calculate cash flow for each year.
Step 2 – Discount those cash flow based on the discount rate.
Step 3 – Add all the discounted cash flow.
Step 4 – Selection of the project

Why Innovation & Entrepreneurship Managers need to know Financial Tools such as Net Present Value (NPV)?

In our daily workplace we often come across people and colleagues who are just focused on their core competency and targets they have to deliver. For example marketing managers at Myopia Nearsightedness often design programs whose objective is to drive brand awareness and customer reach. But how that 30 point increase in brand awareness or 10 point increase in customer touch points will result into shareholders’ value is not specified.

To overcome such scenarios managers at Myopia Nearsightedness needs to not only know the financial aspect of project management but also needs to have tools to integrate them into part of the project development and monitoring plan.

Calculating Net Present Value (NPV) at 15%

After working through various assumptions we reached a conclusion that risk is far higher than 6%. In a reasonably stable industry with weak competition - 15% discount rate can be a good benchmark.

Years	Cash Flow	Net Cash Flow	Cumulative     Cash Flow	Discount Rate @ 15 %	Discounted Cash Flows
Year 0	(10026919)	-10026919	-	-
Year 1	3456776	-6570143	3456776	0.8696	3005892
Year 2	3953525	-2616618	7410301	0.7561	2989433
Year 3	3959363	1342745	11369664	0.6575	2603345
Year 4	3231694	4574439	14601358	0.5718	1847732
TOTAL					10446402

The Net NPV after 4 years is 419483

(10446402 - 10026919 )

Calculating Net Present Value (NPV) at 20%

If the risk component is high in the industry then we should go for a higher hurdle rate / discount rate of 20%.

Years	Cash Flow	Net Cash Flow	Cumulative     Cash Flow	Discount Rate @ 20 %	Discounted Cash Flows
Year 0	(10026919)	-10026919	-	-
Year 1	3456776	-6570143	3456776	0.8333	2880647
Year 2	3953525	-2616618	7410301	0.6944	2745503
Year 3	3959363	1342745	11369664	0.5787	2291298
Year 4	3231694	4574439	14601358	0.4823	1558494
TOTAL					9475943

The Net NPV after 4 years is -550976

At 20% discount rate the NPV is negative (9475943 - 10026919 ) so ideally we can't select the project if macro and micro factors don't allow financial managers of Myopia Nearsightedness to discount cash flow at lower discount rates such as 15%.

Acceptance Criteria of a Project based on NPV

Simplest Approach – If the investment project of Myopia Nearsightedness has a NPV value higher than Zero then finance managers at Myopia Nearsightedness can ACCEPT the project, otherwise they can reject the project. This means that project will deliver higher returns over the period of time than any alternate investment strategy.

In theory if the required rate of return or discount rate is chosen correctly by finance managers at Myopia Nearsightedness, then the stock price of the Myopia Nearsightedness should change by same amount of the NPV. In real world we know that share price also reflects various other factors that can be related to both macro and micro environment.

In the same vein – accepting the project with zero NPV should result in stagnant share price. Finance managers use discount rates as a measure of risk components in the project execution process.

Sensitivity Analysis

Project selection is often a far more complex decision than just choosing it based on the NPV number. Finance managers at Myopia Nearsightedness should conduct a sensitivity analysis to better understand not only the inherent risk of the projects but also how those risks can be either factored in or mitigated during the project execution. Sensitivity analysis helps in –

What are the uncertainties surrounding the project Initial Cash Outlay (ICO’s). ICO’s often have several different components such as land, machinery, building, and other equipment.

What are the key aspects of the projects that need to be monitored, refined, and retuned for continuous delivery of projected cash flows.

What can impact the cash flow of the project.

What will be a multi year spillover effect of various taxation regulations.

Understanding of risks involved in the project.

Some of the assumptions while using the Discounted Cash Flow Methods –

Projects are assumed to be Mutually Exclusive – This is seldom the came in modern day giant organizations where projects are often inter-related and rejecting a project solely based on NPV can result in sunk cost from a related project.

Independent projects have independent cash flows – As explained in the marketing project – though the project may look independent but in reality it is not as the brand awareness project can be closely associated with the spending on sales promotions and product specific advertising.
