Park Co is developing a number of new products. New legislation means that one of these products will not be viable unless additional expenditure, estimated at $2 million, is undertaken. This amount excludes $100,000 which is the estimate of the contribution potentially lost through the delay to another project due to the transfer of resources. To date $4.7 million has been spent on the project. It is estimated that before the change in legislation, $3 million was required to bring the product to the launch stage. What is the sunk cost of the project?
