Buy or Rent: Living in Singapore 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 Buy or Rent: Living in Singapore case study

At Oak Spring University, we provide corporate level professional Net Present Value (NPV) case study solution. Buy or Rent: Living in Singapore case study is a Harvard Business School (HBR) case study written by Ruth S.K. Tan, Zsuzsa R. Huszar, Weina Zhang. The Buy or Rent: Living in Singapore (referred as “Singapore Unit” from here on) case study provides evaluation & decision scenario in field of Finance & Accounting. 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 Buy or Rent: Living in Singapore Case Study

Mr. and Mrs. Wong and their three children had rented a condominium unit in Singapore for the past six years. During that time, they had been watching the property market with the objective of buying a home of their own. A larger unit in the same building finally became available for sale in June 2016. Coincidentally, their rental lease would expire soon after that date. If they decided to buy the larger unit, they would hold it for the next 10 years. Their net gain or loss of the buy versus rent decision would depend on the selling price of the unit at the end of 10 years and the rental payments. Ruth S.K.

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. Net Present Value
3. Internal Rate of Return
4. Profitability Index

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. Singapore Unit 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 Singapore Unit 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 Buy or Rent: Living in Singapore

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 Finance & Accounting 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 Singapore Unit 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 Singapore Unit 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	(10007799)	-10007799	-	-
Year 1	3461144	-6546655	3461144	0.8696	3009690
Year 2	3962244	-2584411	7423388	0.7561	2996026
Year 3	3943914	1359503	11367302	0.6575	2593187
Year 4	3224672	4584175	14591974	0.5718	1843717
TOTAL					10442620

The Net NPV after 4 years is 434821

(10442620 - 10007799 )

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	(10007799)	-10007799	-	-
Year 1	3461144	-6546655	3461144	0.8333	2884287
Year 2	3962244	-2584411	7423388	0.6944	2751558
Year 3	3943914	1359503	11367302	0.5787	2282358
Year 4	3224672	4584175	14591974	0.4823	1555108
TOTAL					9473311

The Net NPV after 4 years is -534488

At 20% discount rate the NPV is negative (9473311 - 10007799 ) so ideally we can't select the project if macro and micro factors don't allow financial managers of Singapore Unit 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 Singapore Unit has a NPV value higher than Zero then finance managers at Singapore Unit 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 Singapore Unit, then the stock price of the Singapore Unit 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 Singapore Unit 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.

Understanding of risks involved in the project.

What can impact the cash flow of the project.

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

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.

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.
