An Intrinsic Calculation For CSR Limited (ASX:CSR) Suggests It's 23% Undervalued

Does the January share price for CSR Limited (ASX:CSR) reflect what it's really worth? Today, we will estimate the stock's intrinsic value by estimating the company's future cash flows and discounting them to their present value. I will use the Discounted Cash Flow (DCF) model. Don't get put off by the jargon, the math behind it is actually quite straightforward.

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. If you want to learn more about discounted cash flow, the rationale behind this calculation can be read in detail in the Simply Wall St analysis model.

The method

We use what is known as a 2-stage model, which simply means we have two different periods of growth rates for the company's cash flows. Generally the first stage is higher growth, and the second stage is a lower growth phase. To begin with, we have to get estimates of the next ten years of cash flows. Where possible we use analyst estimates, but when these aren't available we extrapolate the previous free cash flow (FCF) from the last estimate or reported value. We assume companies with shrinking free cash flow will slow their rate of shrinkage, and that companies with growing free cash flow will see their growth rate slow, over this period. We do this to reflect that growth tends to slow more in the early years than it does in later years.

Generally we assume that a dollar today is more valuable than a dollar in the future, so we need to discount the sum of these future cash flows to arrive at a present value estimate:

10-year free cash flow (FCF) estimate

 2020 2021 2022 2023 2024 2025 2026 2027 2028 2029 Levered FCF (A\$, Millions) AU\$193.7m AU\$111.0m AU\$151.5m AU\$155.0m AU\$158.0m AU\$160.7m AU\$163.1m AU\$165.3m AU\$167.4m AU\$169.5m Growth Rate Estimate Source Analyst x3 Analyst x3 Analyst x2 Est @ 2.31% Est @ 1.94% Est @ 1.68% Est @ 1.5% Est @ 1.37% Est @ 1.29% Est @ 1.22% Present Value (A\$, Millions) Discounted @ 6.3% AU\$182 AU\$98.2 AU\$126 AU\$121 AU\$116 AU\$111 AU\$106 AU\$101 AU\$96.4 AU\$91.8

("Est" = FCF growth rate estimated by Simply Wall St)
Present Value of 10-year Cash Flow (PVCF) = AU\$1.2b

We now need to calculate the Terminal Value, which accounts for all the future cash flows after this ten year period. The Gordon Growth formula is used to calculate Terminal Value at a future annual growth rate equal to the 10-year government bond rate of 1.1%. We discount the terminal cash flows to today's value at a cost of equity of 6.3%.

Terminal Value (TV)= FCF2029 Ã— (1 + g) Ã· (r â€“ g) = AU\$169mÃ— (1 + 1.1%) Ã· 6.3%â€“ 1.1%) = AU\$3.3b

Present Value of Terminal Value (PVTV)= TV / (1 + r)10= AU\$3.3bÃ· ( 1 + 6.3%)10= AU\$1.8b

The total value is the sum of cash flows for the next ten years plus the discounted terminal value, which results in the Total Equity Value, which in this case is AU\$2.9b. The last step is to then divide the equity value by the number of shares outstanding. Compared to the current share price of AU\$4.6, the company appears a touch undervalued at a 23% discount to where the stock price trades currently. Remember though, that this is just an approximate valuation, and like any complex formula - garbage in, garbage out.

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. Part of investing is coming up with your own evaluation of a company's future performance, so try the calculation yourself and check your own assumptions. 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 CSR 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 6.3%, which is based on a levered beta of 0.965. 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.

Next Steps:

Valuation is only one side of the coin in terms of building your investment thesis, and it shouldnâ€™t be the only metric you look at when researching a company. The DCF model is not a perfect stock valuation tool. Rather it should be seen as a guide to "what assumptions need to be true for this stock to be under/overvalued?" If a company grows at a different rate, or if its cost of equity or risk free rate changes sharply, the output can look very different. What is the reason for the share price to differ from the intrinsic value? For CSR, There are three essential factors you should further examine:
