Global Enterprises has spent $134,000 on research developing a new type of shoe. For this shoe to now be manufactured, the firm will need to expand into an empty building that it currently owns. The firm was offered $229,000 last week for that building. An additional $342, 000 will be required for new equipment and building improvements. Labor and material costs are estimated at $4.98 per pair of shoes. Interest expense on the loan needed to finance the production of this new shoe will be $17,800 a year. Which one of these correctly identifies the sunk costs?
