Selling CFLs at Wal-Mart 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 Selling CFLs at Wal-Mart case study


At Oak Spring University, we provide corporate level professional Net Present Value (NPV) case study solution. Selling CFLs at Wal-Mart case study is a Harvard Business School (HBR) case study written by Eric J. Johnson, Daniel M. Bartels. The Selling CFLs at Wal-Mart (referred as “Bulbs Cfl” from here on) case study provides evaluation & decision scenario in field of Sales & Marketing. It also touches upon business topics such as - Value proposition, Sustainability.

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 Selling CFLs at Wal-Mart Case Study


In early 2009, Wal-Mart executive Andy Barron realized the firm's lighting business was facing a challenge. After achieving a goal of selling 100 million compact fluorescent light (CFL) bulbs by the end of 2007, sales of the energy-efficient bulbs had started to plateau, leading to a dim outlook for 2009. Barron needed to examine what barriers might be keeping consumers from adopting more of the bulbs, which offer both cost savings and environmental benefits. In this 2-part case students study the historic price points and sales of CFL bulbs, Wal-Mart's 2007 promotion of CFL lighting, and research about consumer adoption of the bulbs in order to understand how the retailer might achieve its goals. The case asks: How can consumer habits be changed? How can new products overcome barriers to adoption? What can managers do to promote sales of new products, given human behavior where biases, values and emotions have an impact on the choices people make? How can economic theories explain consumer behavior as it occurs in the real world? The Epilogue to the first case asks students to discuss what developments occurred after the 2009 implementation and how they impacted CFL sales.

The Net Present Value at 6% discount rate is 2647246

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 -

Different methods of capital budgeting


What is NPV & Formula of NPV,
How it is calculated,
How to use NPV number for project evaluation, and
Scenario Planning given risks and management priorities.




Capital Budgeting Approaches

Methods of Capital Budgeting


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

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

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






Formula and Steps to Calculate Net Present Value (NPV) of Selling CFLs at Wal-Mart

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 Sales & Marketing 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 Bulbs Cfl 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 Bulbs Cfl 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 (10008233) -10008233 - -
Year 1 3453415 -6554818 3453415 0.8696 3002970
Year 2 3954220 -2600598 7407635 0.7561 2989958
Year 3 3950006 1349408 11357641 0.6575 2597193
Year 4 3234210 4583618 14591851 0.5718 1849170
TOTAL 10439291


The Net NPV after 4 years is 431058

(10439291 - 10008233 )








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 (10008233) -10008233 - -
Year 1 3453415 -6554818 3453415 0.8333 2877846
Year 2 3954220 -2600598 7407635 0.6944 2745986
Year 3 3950006 1349408 11357641 0.5787 2285883
Year 4 3234210 4583618 14591851 0.4823 1559708
TOTAL 9469423


The Net NPV after 4 years is -538810

At 20% discount rate the NPV is negative (9469423 - 10008233 ) so ideally we can't select the project if macro and micro factors don't allow financial managers of Bulbs Cfl 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 Bulbs Cfl has a NPV value higher than Zero then finance managers at Bulbs Cfl 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 Bulbs Cfl, then the stock price of the Bulbs Cfl 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 Bulbs Cfl 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 key aspects of the projects that need to be monitored, refined, and retuned for continuous delivery of projected cash flows.

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 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.
