Smithson Mining operates a silver mine in Nevada. Acquisition, exploration, and development costs totaled $5.6 million. After the silver is extracted in approximately five years, Smithson is obligated to restore the land to its original condition, including constructing a wildlife preserve. The company's controller has provided the following three cash flow possibilities for the restoration costs: (1) $500,000,20% probability; (2) $550,000,45% probability; and (3) $650,000,35% probability. The company's credit-adjusted, risk-free rate of interest is 6%. What is the book value of the asset retirement liability at the end of one year? Assuming that the actual restoration costs incurred after five years are $596,000, what amount of gain or loss will Smithson recognize on retirement of the liability? Note: Use appropriate factor(s) from the tables provided. Do not round intermediate calculations. Enter your answers in dollars not in millions of dollars.
