Earnings Capacity

As demand fluctuates, companies with variable costs can scale up or scale down their operations as neccessary. Companies with fixed-costs, however, have tougher decisions to make. While they can cut costs by disposing assets in the face of waning demand, this ends up reducing capacity, which can bite them later. Over the course of this recession, many companies with high fixed costs that have earned tremendous profits over the last several years have had to dispose of assets at fire-sale prices in order to better align expenses with revenues. For the investor assessing whether a company's stock price trades at a discount to its intrinsic value, how is he to determine a company's earnings power in the face of such asset impairments and plant shutdowns?

For companies in stable industries, we have advocated employing Ben Graham's approach to determining a company's earnings power. While this approach of using a company's average earnings over a representative period is appropriate when the level of assets has not changed substantially, it may not be as useful at a time like this when companies are disposing of significant amounts of fixed assets.

Using the company's current earnings is also not an appropriate measure of a company's future earnings power. Current earnings are riddled with red ink due to current charges for labour reduction programs, asset impairments, and revenue drops that outpaced cost reductions.

While not perfect, a better method to estimating a company's future earnings power when assets have been impaired is by examining the company's record of return on assets. Provided the company is in an industry where technological advances are slow and where prices are stable, there will be, at the very least, a loose relationship between a company's earnings and its assets. By averaging a company's past return on assets over a representative period, and then applying this return to the company's current level of assets, the investor can get a better idea of the company's earnings power than if he estimated earnings power by simply extrapolating the company's current earnings, which are influenced by temporary effects.

The importance of limiting the application of this procedure to companies with price stability can not be stressed enough. For companies in commodity industries with volatile pricing, past returns are not neccessarily reflective of future earnings, and therefore the accuracy of this method reduces to the point where its usefulness is rather limited.

However, even if applied appropriately, it is important to note that this method of calculating a company's earnings power is by no means an exact science. Earnings will rarely be exactly proportional to a company's level of assets. However, for companies in slow-changing industries where price levels remain stable, an examination of the relationship between earnings and assets should assist the investor in making a more informed decision about the earnings power of a company under examination as a potential investment.

For a more advanced exercise, investors considering an investment in a capital intensive business may also try replacing return on assets with return on fixed assets.

I'm curious to know your opinion of Brinx Resources, a company that recently has cut it's assets and therefore revenue of the late and shows red ink due to deferred taxes. But what I'm wondering is how, or if, this should discount it's value below cash levels? It is currently lagging behind cash levels by about 25%, let alone current assets.

By the way... ticker symbol is BRNX. Let me know if you think Gharam and Dodd would have approved.

One thing i noticed when valuing companies is how much a ROE can be pumped up with debt and how an ROE compared with ROA has a quick way of showing this.

I will try using ROA as you have in a few companies i follow

Hi Anthony and Anon,

I believe you both meant bnrx? I have written about it here:

Hi Options,

I totally agree, high ROE can mean extreme risk (high debt), but if its the result of high ROA, it could be a great business.
