Example: Assume that a plan of group-term life insurance has 500 participants, 10 of whom are key employees. Under the plan, 400 of the non-key employees receive an amount of insurance equal to 100 percent of compensation, while all of the key employees and 90 of the non-key employees receive an amount of insurance equal to 200 percent of compensation. The plan will be considered not to discriminate in favor of the participants who are key employees because, tested separately, the group of participants receiving an amount of insurance equal to or greater than 200 percent of compensation would satisfy the requirements of section 79(d)(2)(A) (by reason of section 79(d)(3)(A)(ii)). If one of the key employees received an amount of insurance equal to 300 percent of compensation, the plan would be considered to discriminate in favor of participants who are key employees, because, tested separately, the group consisting of the single key employee receiving an amount of insurance equal to or greater than 300 percent of compensation would fail to satisfy the requirements of section 79(d)(2)(A).
In determining the groups of employees that are tested separately for this purpose, allowance shall be made for reasonable differences in amount of insurance (as a multiple of compensation) due to rounding, the use of compensation brackets or other similar factors. Thus, if a plan bases group-term life insurance coverage on "compensation brackets," it is not intended that any participants will be treated as receiving an amount of insurance (as a multiple of compensation) that is greater (or less) than that of any other participant merely because the first participant's compensation is at the lower (or higher) end of a compensation bracket while the second participant's compensation is at the higher (or lower) end of a compensation bracket. However, any compensation brackets utilized by a plan will be examined to determine if the brackets, or compensation groupings, result in discrimination in favor of key employees. In addition, a plan does not meet the requirements for nondiscrimination as to the type and amount of benefits available under the plan unless all types of benefits (including permanent benefits) and all terms and conditions with respect to such benefits which are available to any participant who is a key employee are also available on a nondiscriminatory basis to non-key employee participants.
