Business Valuation - Discounted Cash Flow
Wednesday, December 19th, 2007In this blog I would like to entertain a high-level discussion of valuing a business by employing the Discounted Cash Flow methodology. Creating a discounted cash flow model does require some basic understanding of the principle of “time value of money,” discount rate and some skill in Excel. The intention of this blog is not to teach these principles in detail, rather to serve merely as an “eye-opener” and encourage small business owners to think more critically about valuing their business.
Discounted Cash Flow analysis consists of two steps. The first is to determine future cash flows for the business or entity being valued. In determining future cash flows there are a few things that should be taken into consideration.
1. What is cash flow? The definition of cash flow, sometime called “free cash flow” can vary slightly depending on the desired approach. However, cash flow is typically defined as cash flow after removing all expenses necessary to run and grow a business over time. Mathematically cash flow can be calculated by taking cash flows after all operating expenses less taxes less necessary investments in working capital and property plant and equipment plus all non-cash expenses (i.e. depreciation).
2. How many years of cash flow should I use in my analysis? Typically the further out you forecast cash flows the less accurate they become. This is where your judgment and expertise in your industry will come into play. If you feel strongly that you understand the industry and that the industry is relatively stable, you may be able to project further into the future. Although somewhat arbitrary, most practitioners limit cash flow projections to 5 years.
As with all analysis, the old adage “Garbage in, Garbage out” holds true with Discounted Cash Flow analysis. The validity of your analysis depends on your ability to make solid cash flow projections. Doing so will require you to understand the drivers of your business as well as industry dynamics.
The second step in the Discounted Cash Flow methodology is to determine a discount rate. A discount rate represents the rate of return you require on an investment and it is the rate at which you will discount future cash flows. It is derived by understanding two things: what is my cost of capital and what is the appropriate risk premium for this organization. Both cost of capital and risk premium will be unique to each individual organization.
1. Cost of capital is a function of the sources of capital an organization chooses to use in order to finance its operations. For example if an organization funds all of its capital expenditures by taking out debt, the cost of capital would simply be the cost of interest paid on that debt. If however, an organization uses equity, the cost of capital on the equity would be the “opportunity cost” of investing the capital in another opportunity. Typically your cost of capital can be calculated by taking a weighted average of the cost of debt and equity financing.
2. Risk premium is much less lucid than cost of capital and will vary greatly with the perspective of the investor or entity valuing your business. For example you may assign a lower risk premium to your business because you understand the industry in which you compete and have existing expertise. However, for a potential acquirer lacking similar expertise, your business may pose more risk, thus requiring the use of a higher risk premium.
After determining cost of capital and risk premium, the sum of the two will comprise your discount rate. Per the principles of “time value of money,” the higher the discount rate used to discount cash flows, the less those cash flows will be worth. So a higher risk premium will lower the value of your business.
The intricacies and nuances of developing a sound Discounted Cash Flow analysis clearly can not be captured in one short blog. However, there are various resources including templates available online that will walk you through, in more detail, the steps of developing a solid analysis. Your effort to value your business before you sell it will empower you when it comes time to negotiate a selling price.
