Definīcija:A determination by an actuary of the value of a pension plan's assets and its liabilities. The valuation, which is based on statistical probability, is used to determine if the assets are adequate to fund the plan's liabilities. If the value of the assets is not adequate, the plan sponsor must increase its contributions to make up the deficiency; if the assets are more than adequate, the plan sponsor can reduce contributions. Also called plan valuation.
