[1] Net premiums represent the portion of gross premiums collected from policyholders that is necessary to fund expected benefit payments.
[2] Flooring adjustments are necessary when the present value of future net premiums exceeds the present value of future benefits for a given cohort. The flooring adjustment is the total of the flooring adjustments for each cohort, if any.  These adjustments ensure that the liability for future policy benefits is at least zero for all cohorts.
