Bell and Mayo are independent entities. Each owns a tract of land being held for development. However, each would prefer to build on the other s land. Accordingly, they agreed to exchange their land. From an independent appraisal report and the entities records, the following information was obtained: Bell s Land Cost and carrying amount: $80,000, Fair Value: $100,000. Mayo s Land Cost and carrying amount: $50,000, Fair Value: $85,000. Based on the difference in fair values, Mayo paid $15,000 to Bell. If Mayo did not consider the exchange to have commercial substance, at what amount should Mayo record the receipt of land?
