If the STD Plan provides pay for approved periods of disability that are later determined to be as a result of an illness or injury for which another person or company is legally responsible, the STD Plan has the right to recover payment from you or from the person or company who is determined to be legally responsible. Assignment of your claim to a third party does not exempt you from your responsibility for repaying the STD Plan. You must notify the STD Plan promptly of any circumstance in which a third party may be responsible for compensating you with respect to an illness or injury that results in the STD Plan providing financial protection for approved periods of disability.
