Each customer is a member and owner of the business. This means that all members have equal individual authority, unlike investor-owned utilities where the extent of individual authority is governed by the number of shares held. Like cooperatives operating in other sectors, many utility cooperatives conduct their affairs according to a set of ideals based on the Rochdale Principles. Some utility cooperatives respect the seventh principle, "Concern for community", through "Operation Roundup" schemes, whereby members can voluntarily have their bill rounded to the next currency unit (e.g. $55.37 becomes $56), with the difference (e.g. 63¢) distributed to a fund for local charities.
