The Fair Political Practices Commission (FPPC) requires each agency to post a single Form 806 (FPPC Regulation 18702.5). 

The Form 806 reports additional compensation that officials receive when appointing themselves to positions on other boards, commissions or committees of a public agency, special district, and joint power agency/authorities.  Each agency must post a single Form 806 listing all paid appointed positions including the date appointed, length of term and stipend amount.

For more information on the Form 806, please see the FPPC's website here.
