Oh GOD..
I'm brazilian and i had to register here just to explain some stuff...with a bad source everything gets mixed up and some people that don't know what they're saying just keep saying non-sense.
1 - Yes, tax here are high, but OF COURSE THAT 500mi won't make it 833mi in taxes. In this 833 milions it's included: TAXES, but over the 5 years that went by (meaning: if they didn't pay the tax in 2002, for example, in 2007 the present value it's not the same...), and the FINE as well.
So, 833mi = FINE + TAXES + "CORRECTION" (don't know if this words existis in english) of the Present Value over 5 years
Don't come and say that Cisco is right, it's just stupid, you know why?
This didn't started yesterday, when the company went to Brazil they knew how much they would have to pay with taxes. It's not "Let's go to Brazil...5 months go by...OMG LOOK AT THIS TAX". They knew it. If they think it's too much, they can go anywhere else.
The other companies pay it, so they were just trying to be the smart ones.
