COGS has been going up year by year. For year 14 to 15 it went up three percent but from 15 to 16 it only rose by 1.8 percent which means they were able control prices. Unfortunately it has not been enough because profit margins have been decreasing yearly.They have been able to cut down on operating expenses.Operating margin has gone on the decline as well. They went from earning 14 cents on the dollar to now earning 11 cents. The tax rate has been decreasing but at a very minimum. Overall the company is losing money each year because each year they are left with a smaller percentage of net profit margins. So this company is heading towards the wrong direction.
