My exemption would not operate unless this test were met. This implies an additional test which is that the employer assumes the responsibility for the cost of those benefits. whether the cost goes up or down. A typical example of how this type of plan might work was demonstrated last year for the employers who had levelofbenefit funds which contained sickness benefits. Many of the beneficiaries of such funds were hard hit by the Asiatic flue. Under such circumstances. the cost to the employer. not that year. but the next year. went up. The employer had to assume those costs.
