Examining Cashflow Against Kunshan Dongwei TechnologyLtd's Earnings

In high finance, the key ratio used to measure how well a company converts reported profits into free cash flow (FCF) is the accrual ratio (from cashflow). To get the accrual ratio we first subtract FCF from profit for a period, and then divide that number by the average operating assets for the period. You could think of the accrual ratio from cashflow as the 'non-FCF profit ratio'.

That means a negative accrual ratio is a good thing, because it shows that the company is bringing in more free cash flow than its profit would suggest. While it's not a problem to have a positive accrual ratio, indicating a certain level of non-cash profits, a high accrual ratio is arguably a bad thing, because it indicates paper profits are not matched by cash flow. Notably, there is some academic evidence that suggests that a high accrual ratio is a bad sign for near-term profits, generally speaking.

Kunshan Dongwei TechnologyLtd has an accrual ratio of 0.49 for the year to December 2021. That means it didn't generate anywhere near enough free cash flow to match its profit. As a general rule, that bodes poorly for future profitability. Indeed, in the last twelve months it reported free cash flow of CN¥30m, which is significantly less than its profit of CN¥160.9m. Kunshan Dongwei TechnologyLtd shareholders will no doubt be hoping that its free cash flow bounces back next year, since it was down over the last twelve months. However, that's not all there is to consider. The accrual ratio is reflecting the impact of unusual items on statutory profit, at least in part.

How Do Unusual Items Influence Profit?

The fact that the company had unusual items boosting profit by CN¥12m, in the last year, probably goes some way to explain why its accrual ratio was so weak. While we like to see profit increases, we tend to be a little more cautious when unusual items have made a big contribution. When we crunched the numbers on thousands of publicly listed companies, we found that a boost from unusual items in a given year is often not repeated the next year. And that's as you'd expect, given these boosts are described as 'unusual'. Assuming those unusual items don't show up again in the current year, we'd thus expect profit to be weaker next year (in the absence of business growth, that is).

Our Take On Kunshan Dongwei TechnologyLtd's Profit Performance

Kunshan Dongwei TechnologyLtd had a weak accrual ratio, but its profit did receive a boost from unusual items. For the reasons mentioned above, we think that a perfunctory glance at Kunshan Dongwei TechnologyLtd's statutory profits might make it look better than it really is on an underlying level.
