Should You Expect Interface Inc (NASDAQ:TILE) To Continue Delivering An ROE Of 17.67%?

Daryl Painter

Interface Inc (NASDAQ:TILE) outperformed the Office Services and Supplies industry on the basis of its ROE – producing a higher 17.67% relative to the peer average of 13.29% over the past 12 months. While the impressive ratio tells us that TILE has made significant profits from little equity capital, ROE doesn’t tell us if TILE has borrowed debt to make this happen. We’ll take a closer look today at factors like financial leverage to determine whether TILE’s ROE is actually sustainable. Check out our latest analysis for Interface

Breaking down Return on Equity

Firstly, Return on Equity, or ROE, is simply the percentage of last years’ earning against the book value of shareholders’ equity. It essentially shows how much the company can generate in earnings given the amount of equity it has raised. In most cases, a higher ROE is preferred; however, there are many other factors we must consider prior to making any investment decisions.

Return on Equity = Net Profit ÷ Shareholders Equity

Returns are usually compared to costs to measure the efficiency of capital. Interface’s cost of equity is 8.49%. Since Interface’s return covers its cost in excess of 9.17%, its use of equity capital is efficient and likely to be sustainable. Simply put, Interface pays less for its capital than what it generates in return. ROE can be split up into three useful ratios: net profit margin, asset turnover, and financial leverage. This is called the Dupont Formula:

Dupont Formula

ROE = profit margin × asset turnover × financial leverage

ROE = (annual net profit ÷ sales) × (sales ÷ assets) × (assets ÷ shareholders’ equity)

ROE = annual net profit ÷ shareholders’ equity

Essentially, profit margin shows how much money the company makes after paying for all its expenses. Asset turnover reveals how much revenue can be generated from Interface’s asset base. The most interesting ratio, and reflective of sustainability of its ROE, is financial leverage. Since ROE can be artificially increased through excessive borrowing, we should check Interface’s historic debt-to-equity ratio. The debt-to-equity ratio currently stands at a sensible 72.08%, meaning the above-average ROE is due to its capacity to produce profit growth without a huge debt burden.

ROE is a simple yet informative ratio, illustrating the various components that each measure the quality of the overall stock. Interface’s above-industry ROE is encouraging, and is also in excess of its cost of equity. Its high ROE is not likely to be driven by high debt. Therefore, investors may have more confidence in the sustainability of this level of returns going forward. ROE is a helpful signal, but it is definitely not sufficient on its own to make an investment decision.
