Wpf A with-profits fund (WPF) is a fund that the insurance company uses to write its with-profis business into. It could also write other business in this fund as well, in which case, it might be the only business fund the company has. In addition to a WPF, a company might have a separate non-profit fund that only contains without-profits and unit-linked business. In fact, it could have several of each if it has gone through structural changes, mergers and takeovers in the past. A proprietary will also have a shareholders' fund as well, that shareholders' profits from the business funds are transferred into, before being paid out to the shareholders as a regular stream of dividends.
