Equity for board members

Hi,

I'd love to know if anyone has guidelines for board member equity. We are a Series C fintech and I need to refresh the equity for an independent board member sho has been with us for a few years and also consider equity for future board members who are not investors. Has anyone seen a benchmark report or guidelines for board member equity at Series C and beyond companies?

Thanks!
