Today we'll do a simple run through of a valuation method used to estimate the attractiveness of California Water Service Group (NYSE:CWT) as an investment opportunity by taking the expected future cash flows and discounting them to today's value. One way to achieve this is by employing the Discounted Cash Flow (DCF) model. There's really not all that much to it, even though it might appear quite complex.

We generally believe that a company's value is the present value of all of the cash it will generate in the future. However, a DCF is just one valuation metric among many, and it is not without flaws. Anyone interested in learning a bit more about intrinsic value should have a read of the Simply Wall St analysis model.

The Method

As California Water Service Group operates in the water utilities sector, we need to calculate the intrinsic value slightly differently. In this approach dividends per share (DPS) are used, as free cash flow is difficult to estimate and often not reported by analysts. This often underestimates the value of a stock, but it can still be good as a comparison to competitors. We use the Gordon Growth Model, which assumes dividend will grow into perpetuity at a rate that can be sustained. For a number of reasons a very conservative growth rate is used that cannot exceed that of a company's Gross Domestic Product (GDP). In this case we used the 5-year average of the 10-year government bond yield (2.6%). The expected dividend per share is then discounted to today's value at a cost of equity of 5.9%. Compared to the current share price of US$49.1, the company appears slightly overvalued at the time of writing. The assumptions in any calculation have a big impact on the valuation, so it is better to view this as a rough estimate, not precise down to the last cent.

Value Per Share = Expected Dividend Per Share / (Discount Rate - Perpetual Growth Rate)

= US$1.3 / (5.9% – 2.6%)

= US$39.9

Important Assumptions

We would point out that the most important inputs to a discounted cash flow are the discount rate and of course the actual cash flows. You don't have to agree with these inputs, I recommend redoing the calculations yourself and playing with them. The DCF also does not consider the possible cyclicality of an industry, or a company's future capital requirements, so it does not give a full picture of a company's potential performance. Given that we are looking at California Water Service Group as potential shareholders, the cost of equity is used as the discount rate, rather than the cost of capital (or weighted average cost of capital, WACC) which accounts for debt. In this calculation we've used 5.9%, which is based on a levered beta of 0.800. Beta is a measure of a stock's volatility, compared to the market as a whole. We get our beta from the industry average beta of globally comparable companies, with an imposed limit between 0.8 and 2.0, which is a reasonable range for a stable business.

SWOT Analysis for California Water Service Group

Moving On:

Whilst important, the DCF calculation ideally won't be the sole piece of analysis you scrutinize for a company. DCF models are not the be-all and end-all of investment valuation. Instead the best use for a DCF model is to test certain assumptions and theories to see if they would lead to the company being undervalued or overvalued. For instance, if the terminal value growth rate is adjusted slightly, it can dramatically alter the overall result. Why is the intrinsic value lower than the current share price?
