Capital Investment

Discounted cash flow, rate of return and what really happens.
The standard method for assessing the value of an investment relies on some idea of yield to redemption or internal rate of return (ROR, IROR). For such an assessment, the future cash flows from the investment, whether it is a financial instrument or a new factory, are converted to a present day equivalent value. To do this, future revenues are discounted by some interest rate to see what they are worth in today's money. Then the plus and minus flows are balanced off against each other as if they were all in today's money. A big resulting positive value is good, a small or negative one is bad. In a slightly more subtle form, the differences between various alternatives (such as: do nothing, project A, project B etc.) are similarly assessed.

Several years of experience (as a planning manager) doing the corporate standard procedures for capital investment in which the results were expressed as a rate of return (yield to redemption, the imputed discount rate that would make the future benefits just match the near-term costs) led to the observation that reality didn't match the projections. Often it was the market projections that were the cause, less often the capital, engineering and operating costs.

Desperation and Evangelical Projects
The first observation is that there were two main classes of project proposal. The class coming from the operations side of the business were of the desperation type: "If you don't do this we won't be able to continue in business!" . The others from the marketing side were of the evangelical type: "This opportunity is so good you can't afford to miss it". Either could be computed to make a high rate of return, as all involved the differences of large numbers that were not well known and subject to 'estimation' (i.e. guessing). As a result, proposals were massaged to come within an acceptable range for presentation to the board for sanction. If the rate of return was seen as too high it wasn't believable and if too low it wasn't acceptable.

Mismatch with Long Term results
It was also obvious that long term corporate results didn't match the rates of return implicit in the individual projects which collectively had defined the base capital investment on which the business stood. If all the brilliant proposals had worked the company would have taken over the world.

A different approach
We assembled a model of the whole business to look at its cash flow as a dynamic system, this allowed us to inject projects, over a period of time, see the cash flow consequences they had, not only as individual projects but on the corporation as a whole. Every real world activity had its reflection in a money flow. We could adjust gearing (leverage, debt vs shareholders equity) and see how the policies would work out over a long time scale. True, it's only arithmetic, but it is a closed loop system in which previous investments produce returns (or not) to fund current activities. And, very importantly for conveying ideas, being able to see graphically the consequences of policies and choices does help in understanding what is going on.

Other Experience
My experience with problems over these time scales is that people rarely expand their time horizons far enough to see the whole picture. Even if they try, they tend to miss interaction effects and think more in terms of extrapolating, sometimes with statistical models, from the recent past. It's my (MJMcC) observation that the finance, demographics and the compelling force of reality can be quantified to make a big improvement in perception. You only have to contact me. There's no charge for finding out that I can help.

Invitation. McCann can help if you have a design or operational problem that needs some technical support that is outside your team's experience, some quantitative assessment of what is really the cause of the difficulties, some design alternatives or just a fresh look by an intelligent interrogator.
If you have a problem with the behaviour of a market sector, plant, process or item of equipment and would like to get a quantitative handle on it to improve yield or optimise performance, then contact me. I'm always ready to give a little time to discuss a new puzzle, in confidence, of course. We'll only worry about fees when there is some defined work. I can be flexible about how I work with you.
