"Board members are typically paid an annual salary and a performance-based bonus, often in the form of company stock. According to the executive search firm Spencer Stuart, the average total compensation for board members at the almost 500 publicly-traded companies in their 2011 annual survey was $232,142. This figure increased to $242,385 in 2012. Privately-held companies do not have to release board of director compensation figures."
