click counts, but no pay

Is there anythig wrong with the reporting

[foodconsumer]

This is about google's adsense tracking and or reporting.

Today I noticed that the report shows One click for Wed., but the pay is 0.00. Anyone can explain why?
I know google's minimal charge is 0.05 per click. If the click is on a 0.05 dollar link ad, then I am supposed to get at least 0.01 dollar? (20%). I don't understand.

Thanks.

It is likely an invalid click (doesn't neccessarily mean it was fraudulent - the same IP might have clicked the same ad elsewhere within a short period of time.)

Here is a more in depth look into this from a few days ago:
