Here are all the California companies without a female in the boardroom.

On Sept. 30 California became the first state to mandate companies put women on corporate boards.

If you're a woman looking to get into the boardroom, or to add to your director positions, you may want to start networking with your contacts in California because there are nearly 100 corporations with no female board representation. Under the new law, those companies will have to add a female director by the end of next year, and a minimum of two by 2021.
