Based off of the $510 million in employee stock compensation the Cityville maker reported to the SEC last week, the company would have owed the city upwards of $6 million in funds that could have covered city budget shortfalls. Of course, as District 2 Supervisor Mark Farrell rightly pointed out: if Zynga had packed up their Farmvilles and left for the sunnier tax climates of the peninsula, none of that money would have gone to the city anyway.

Thanks to the city's tax break on those employee stock options, Zynga will pay the same taxes it paid in 2010 - $750,000 in this case.

Zynga's stock, which hit the market back in December after the company had to ask for some of it back, quickly flopped around only to end up down about a buck-fifty in its first day of trading. It's currently sitting up around $13.
