Noncash consideration - transaction price

[volkan.akin]

Under US GAAP, if a services company that would otherwise request a client to pay an upfront fee for a portion of the charges relating to these future services instead asks its customer to provide it with a promissory note that would unconditionally be payable (in lieu of upfront payment), how would this be accounted for. The question here pertains to the ASC 606 transaction price for revenue recognition purposes specifically, would this be the present value of that promissory note as it would be considered a noncash consideration exchanged (i.e. a financial instrument, so a financial commitment instead of cash) that should be measured at its fair value?
