UJI 13-713. Present value; determination; discount.

In fixing the amount you may award for damages arising in the future, you must reduce the total of such damages by making allowance for the fact that any award you make would, if properly invested, earn interest. To determine “present value”, you should, therefore, allow a reasonable discount for the earning power of such money and arrive at the present cash value of the total money damages, if any. Damages, not arising in the future, shall not be discounted.
