I am trying to reconcile books for clients all the way back to 2014.  I came across a unique situation with them. 

The owner bought the business equipment, rolling stock, customer list, software, and other business items but not for cash. He bought all of it in exchange to honor coupons to former clients (270k) that had been screwed over by prior businesses bankruptcy.  How do i show equity into the business? how do i track these coupons?
