“There are no committees that have the authority to act on behalf of the board.”
“The form 990 is prepared by the organization's outside public accounting firm based on information provided by management. Once a draft of the return is available, it is reviewed by management with any changes or revisions incorporated into the filing. The final tax return is presented to the board for review and receives approval and signature before mailing.”
“Individuals holding designated positions shall file their statements of economic interests with river montessori charter school, which will make the statements available for public inspection and reproduction. The chief business officer ensures all board members and officers file the annual form 700 with the county. If a conflict of interest arises with any voting member, they recuse themselves from voting.”
“Review and approval of the executive director's compensation package is undertaken during an open session of the board of directors. The compensation package is compared to other like positions within sonoma county school districts. The chief business officer shows the board comparable salaries and suggests compensation for the current year budget. The board then votes on approval of the salary.”
“Organization documents are publicly available on the rmcs school website, on-site and by request.”
“The process for selecting the independent accounting firm has not changed form the prior year.”
“The school is a non-profit entity exempt from the payment of income taxes under internal revenue code section 501(c)(3) and california revenue and taxation code section 23701d. Accordingly, no provision has been made for income taxes. Management has determined that all income tax positions are more likely than not of being sustained upon potential audit or examination; therefore, no disclosures of uncertain income tax positions are required. The school is subject to income tax on net income that is derived from business activities that are unrelated to the exempt purposes. The school files an exempt school return and applicable related business income tax return in the us federal jurisdiction and with the california franchise tax board.”
