My guess is that those with less than 12 months are normally given nothing and everyone who normally receives nothing like new people, interns and cafe workers only got $100. It probably seemed like a good idea at the time but giving someone who would have received a fat bonus and has put in 6 months $100 is kind of insulting. If true they should use the same calculation they use for other developers, divide the total by 12 and then multiply it by the number of months the employee has been there.
