Then you can look at return on assets going into asset turnover,

and what they call net margin percent, it's what I call return on sales.

It's the profitability.

And you can see the profitability up and then sort of down again.

Which is tracking what we saw with ROA.

And asset turnover has been up and down as well.

But what we really need is to find three or four of 3M's closest competitors,

and then compare these ratios to the competitors, to see whether these trends

are specific to 3M or whether there's some kind of industry of fact that's going on.

But, based on my knowledge of the industry,

these are still pretty healthy ROE and ROA numbers.

And then above, we have the profit margin breakdown, so we have gross margin,

which is really high, almost 50%,

SGNA to sales, which has been fairly flat, and operating margin.

You also get R and D in a sales sense it is a company that does R and

D, and so we get to see the profitability margin ratios as well.

In case you're wondering, the TTM column on the far right, that stands for trailing

12 months, so that's the last 12 months before the date of the ratio calculation.
