Q:

Why does depreciation not show up in my income statement?

I'm looking at a company's 10-K which gives me the following line items:
Income statement

Net sales
Cost of goods sold
Gross profit
Selling, general and administrative expenses
Operating income
Other income (loss)
Income before income taxes
Income tax expense
Net income

Why is there no Depreciation expense line item on this income statement? I thought typically Income before tax was calculated over the operating income less interest and depreciation. On the cash flow statement it does give a Depreciation expense line item.
Any suggestions?
Also what if the notes to Financial Notes do not really indicate which IS line item is tied to to D&A expense? 

A:

Here the depreciation & amortization expenses are not just displayed as separate items. Rather, they are probably in this case included in Selling, general and administrative expenses, as well as Cost of goods sold -items. 
One of the possible reasons for not displaying depreciation as a separate item could be that it is natural to allocate the depreciation to different items. In this case some of the depreciation could be directly related to producing the products (thus attributable to COGS), while some of the depreciation might have more to do with general overhead (and thus included in Selling, general and administrative expenses).
