If an employee accepts a promissory note that is negotiable and is remuneration for employment, the payment is wages. The face value of the note
            on the date it is given to the employee is the amount used as wages.
         
         If an employee accepts a promissory note that is non-negotiable  and is remuneration for employment, the payment is also wages if it is given and
            accepted as unconditional payment for services. The fair market value of the non-negotiable
            note must be determined.
