In a long-term disability (LTD) benefits case, the district court has discretion to grant an award of prejudgment interest. Prejudgment interest has become a familiar remedy widely recognized by federal courts as a means to make a plaintiff whole against a malingering. The reason for adding interest to the award of LTD benefits is that money has a time value, and prejudgment interest is therefore necessary in the ordinary case to compensate a plaintiff ERISA for a loss suffered on a certain date but not compensated until later. Moreover, prejudgment interest is a well-established remedy for LTD claimants. Interest is not recovered according to a rigid theory of compensation for money withheld, but is given in response to considerations of fairness, the Supreme Court has ruled.
