smoothing - Investment & Finance Definition
A process used in pension fund accounting by which unusually high returns in a given year are spread over a multi-year period. The logic behind smoothing is that it lowers the volatility of the profit and loss credit from pension fund returns. During the bull market of the late 1990s, smoothing helped companies boost up their earnings by including gains from pension fund returns.
