Each carrier has an affirmative obligation to urge its respective group policyholder-clients to take reasonable steps to assure that those insured by the group policy or subscriber contract have been exposed to reasonably concise explanations, with as little technical terminology as is commensurate with accuracy, as to the purpose and operation of COB. Such educational effort may take the form of articles in the company magazines or newspapers, speeches before the appropriate labor organization in the case of a unionized company, brochures added to pay envelopes, notices on the company bulletin board, material used by personnel department in counseling employees, and the like.
