Response to the following problem:
Island Corporation invested $1,000,000 in a new product on January 1, 2000. This product generated cash flows of $800,000 the first year, $400,000 the second year, and $200,000 the third year. At the end of the third year, Island abandoned the new product and disposed of the production equipment for $400,000 at the end of the third year.
If these are the only cash flows from this new product, what was Island's return on their investment in this product?
