On February 12, 2018, Forest Incorporated purchased the right to remove timber from a 10,000-acre tract of land over the next three years, and the company estimates no residual value. The timber is to be sold as lumber for new home construction. The cost of the timber rights was $240,000, with estimated salable timber feet of 750,000. During 2018 and 2019, Forest harvested and sold 600,000 feet of timber. What is the book value of the timber rights at the end of 2019, assuming the company uses the units-of-production method?
