Winston Land and Cattle Company is a large operator of cattle feedlots and steak and restaurants. Its recent financial statements showed their real estate holdings to be in excess of $50.0 million. Winston recently had a company wide appraisal done for insurance purposes, and the report showed real estate to have a current market value of $356.0 million. Jim Winston, the owner, requested that the firm's auditors show that value on the financial statements, and the auditors declined his request because: A. Estimates are not allowed in recording transactions. B. The cost principle in most cases, doesn't allow asset markups. C. The auditors don't trust the appraisal firm, D. Restating all prior financial statements is too much work.
