Certain NPCs may also operate as service providers or charities. They may be set up as an informal group, a trust, a cooperative, or a not-for-profit business. Similar to foundations in operation, supporting companies have some restrictions on the organizations they can assist, a more difficult administration process, and a more favorable tax position. Being successful does not mean being wealthy; rather, it means adding value to the populations they manage. Every registered NPO is required to abide by the NPO Act’s provisions.
