Accommodation Line
  
The contract wasn't perfect. It stipulated that payment had to be made in U.S. dollars. But you had saved a boat-load of Zimbabwean dollars from your previous business brokering rhino horns. In the contract, you created an accommodation line to accommodate that the stream of payments required could be paid either in U.S. dollars or in Zimbabwean dollars at a ratio of 600,000:1.
