Question

The Hard Rock Mining Company has just completed the first year of operations at its new strip mine, the Lonesome Doe. Hard Rock spent $10 million for the land and $20 million in preparing the site for mining operations. The Mine is expected to operate for 20 years. Hard Rock is subject to environmental statutes requiring it to restore the Lonesome Doe Mine site on completion of mining operations. Based on its experience and industry data, as well as current technology, Hard Rock forecasts that restoration will cost about $10 million when it is undertaken. Of those costs, about $4 million is for restoring the topsoil that was removed in preparing the site for mining operations (prior to opening the mine). The rest is directly proportional to the depth of the mine, which in turn is directly proportional to the amount of ore extracted.

Should Hard Rock recognize a liability for site restoration in conjunction with the opening of the Lonesome Doe Mine? If so, what is the amount of that liability?

After Hard Rock has operated the Lonesome Doe Mine for 5 years, new technology is introduced that reduces Hard Rock's estimated future restoration costs to $7 million, $3 million of which relates to restoring the topsoil. How should Hard Rock account for this change in its estimated future liability?
