Lecture 8: Project Analysis and Evaluation 1
Lecture 8 (Chapter 11):
Project Analysis and Evaluation
• Discounted cash flow analysis is a very powerful tool, but it is not easy to use.
• We have already seen one difficulty:
– How do we identify the cash flows?
• Today we begin to focus on a second difficulty:
– What if our cash flows are not certain?
• Risk plays a crucial part in DCF analysis. To understand cash fl ow risk, we will use several tools:
– Scenario analysis – Sensitivity analysis
• Break-even analysis
• Operating leverage – Simulation analysis
Capital Rationing
Definition: A situation where a firm has positive NPV projects, but cannot obtain funding to undertake them.
• Soft Rationing: Firm sets internal limits on capital available to its divisions.
Ø Used by firms as an alternative means of controlling investments where DCF is too hard or not understood.
• Hard rationing: Capital markets refuse to finance the firm.
Ø If the firm was willing to pay a high enough rate, could it find someone to invest? If so, perhaps the opportunity cost of capital was calculated incorrectly. If not, perhaps the cash flows are not correct.
Ø Market inefficiency (asymmetric information)
Lecture 8: Project Analysis and Evaluation 3
Evaluating NPV Estimates
• The cash flows that we use in DCF analysis are projections of the future.
• What will be the effect if these projections turn out to be inaccurate?
Ø Forecasting risk: bad projections can lead to bad decisions
• One way to look for problems in DCF is to ask: Why should we expect this project to have a positive NPV?
• The project must be better than all the alternatives available to the investor (opportunity cost of capital)
• Where is the source of value?
• Innovation, Low cost, Market niche, Economies of scale/scope
• How competitive is the market?
Lecture 8: Project Analysis and Evaluation 4
“What-if” Analysis
• What happens if our projections turn out to be wrong?
• Start with a Base Case that gives our best estimate of the future cash flows.
• Then vary the cash flows using
– Scenario analysis: imagine different possible states of the world, and project cash flows and NPVs for each state.
– Sensitive analysis: change one input variable and see how this affects the resulting NPV.
• Break-even Analysis: find the value of an input variable (typically sales) that sets the projects NPV to zero
• Operating Leverage: the degree to which a change in sales impacts the NPV
– Simulation analysis: use random variables as inputs and calculate NPV many times to determine the distribution of possible NPVs .
Lecture 8: Project Analysis and Evaluation 5
Example Base Case
• Fairways Driving Range expects rentals to be 20,000 buckets at
$3 per bucket. Equipment costs $20,000 and will be depreciated straight-line over 5 years and have a $0 salvage value. Variable costs are 10% of rentals and fixed costs are $45,000 per year.
Assume no increase in working capital nor any additional capital outlays. The required return is 15% and the tax rate is 15%.
Scenario Analysis
• Imagine three states of the world:
– Base case (our best estimate)
• Rent 20,000 buckets
• Variable costs are 10% of revenues – Best case (everything works out perfectly)
• Rent 25,000 buckets
• Variable costs are 8% of revenues – Worst case (nothing goes like it should)
• Rent 15,000 buckets
• Variable costs are 12% of revenues
• How will this change our decision?
Lecture 8: Project Analysis and Evaluation 7
Sensitivity Analysis
• Change only one input variable at a time and see how the NPV is affected.
• Find which assumptions are the most important – We can then spend more time checking these
assumptions
• Gives us an idea of the riskiness (variability) of our NPV estimate
• Focus on variables that cannot be directly controlled by the firm to see the effects of “nature” on our project.
• For example, try “optimistic” and “pessimistic” values.
Lecture 8: Project Analysis and Evaluation 8
Break-Even Analysis
• Find the level of sales that the project must achieve to have a positive NPV
• Remember “finding the bid price” from Lecture 7?
• Set NPV = 0 and solve for sales.
• Often it won’t be so easy to solve by hand.
• Question: What is the break-even level of the discount rate
called?
Lecture 8: Project Analysis and Evaluation 9
Accounting Break-Even Analysis
• Level of sales that results in zero EBIT and Net Income
• EBIT = Sales*3*(1-0.1) – 45,000 – 4,000 = 0 Ø Sales = 18,148
• General formula: Sales = (FC + Dep)/(Price – var cost)
• Note that when EBIT = 0, Net Income = EBIT*(1-tax) = 0
• Accounting break-even < Financial break-even (typically) – Ignores time-value of money
• So NPV < 0 at accounting break-even level of sales – What is the IRR?
Cash Break-Even Analysis
• Level of sales that results in zero yearly cash flow
• OCF = { [Sales*3(1 – 0.1) – 45,000 – 4,000]*(1-0.15) + 4,000} = 0 Ø Sales = 16,405
• Textbook General formula: Sales = FC/(Price – var cost)
• But this ignores effect of taxes
• Cash break-even < Accounting break-even < Financial break-even – Initial investment completely ignored
– NPV = -Investment – IRR = -100%
• Cash Break-Even is useful for the treasurer/cash manager to determine working capital needs
Lecture 8: Project Analysis and Evaluation 11
Operating Leverage
• Degree of Operating Leverage (DOL): The degree to which a change in sales affects Operating Cash Flow
– Can also be expressed as: the ratio of fixed costs to OCF
• DOL = 1 + FC/OCF
• Projects with high operating leverage have high fixed costs and low variable costs
Intuition: In a project with high fixed costs and low variable costs, a change in the level of sales will have a large impact on OCF because revenues will increase while costs will stay steady.
High operating leverage ? riskier OCF
Lever
Lecture 8: Project Analysis and Evaluation 12
Leverage
• The Degree of Operating Leverage is often a choice of the firm.
– High DOL examples:
– Low DOL examples:
• A related concept is “Financial Leverage”: the degree to which changes in EBIT affect earnings.
• Financial leverage is higher for firms with higher debt loads – Changes in revenues have greater effect on shareholders – Resulting rate of return is riskier
• Operating leverage and financial leverage are chosen to
compliment each other.
Lecture 8: Project Analysis and Evaluation 13
Simulation Analysis
• Scenario analysis and sensitivity analysis are both very limited in their ability to reflect all the possible outcomes.
• Simulation analysis lets us describe possible values of the inputs in a much more complete way (often as random variables), and lets us vary many inputs at the same time.
– Too difficult to solve analytically
Ø Monte Carlo Simulations
• Sample the input variables many times, and each time calculate the NPV, then analyze the distribution of possible NPVs.
• Time consuming, so let the computer do it.
Managerial Flexibility (Options)
• We have imagined the sole job of the manager as a “yes/no”
then wait for the outcome.
• In reality, managers get the “big bucks” because they need to be constantly making decisions as the project progresses:
– Should we wait before deciding
– Should we expand/contract the project – Should we switch inputs
– Should we abandon the project
• This flexibility increases the value (and hence the true NPV)
of the project
Lecture 8: Project Analysis and Evaluation 15
Valuing Managerial Flexibility
• Our basic DCF analysis cannot handle decisions made after a project is accepted, but all is not lost.
• Decision trees: Map out all the possible outcomes and the decisions that we will take in each case, and then value the resulting cash flows.
• Real Options: Use the techniques developed for financial options (call options, put options, etc), to value options on real assets.
• These techniques are very powerful and important, but they must await another course.
