I've never had a need, or a desire, to delve into the financial documents of a public company before so I have a question that I'm wondering if anyone here can answer, or point me to an official type document concerning:

According to securities laws (SEC), how much disclosure detail is required outlining sources of revenue and how it is calculated?

Specifically, I'd like to know if it's possible to discover percentages of clawback from Adsense Publishers versus refunds to AdWords Advertisers.

Would that be beyond public disclosure and simply presented as an aggregate value in yearly financial reports?

The math just isn't adding up. So much of the economy on so many levels, not only in the US but worldwide, is in or near recession levels yet a very small percentage of companies such as this example continue to forge ahead in abnormal manners.

Other than that, I wonder if they will now consider paying their shareholders some money in the form of quarterly dividends. Looks like the share price has reached a level where stockholders might now start cashing in on their capital gains profits (due to lack of investment income from dividends). Wouldn't surprise me to see share price fall back to mid 900s soon due to profit-taking.

Oh one last thought/question. I have very little experience in advertising. Is it possible that during down times in economies that companies spend more in advertising to try to maintain market share? And when times are good and people aren't holding on to their disposable income with tight fists is there less need to advertise?

From a logical perspective that would be the only thing that could explain this phenomenon of unabated growth?
