Will I Lose Coverage?
Under federal law, you may elect to continue coverage under the Company's health insurance plans during your military service, up to a maximum of 24 months. Your coverage and cost for coverage continue as if you were an active Company employee during your first 30 days of military service. If your military service continues for more than 30 days, you [may be] required to pay up to 102% of the full premium applicable under the plan.
