Conan O’Brien Logging and Lumber Company owns 3,800 acres of timberland on the north side of Mount Leno, which was purchased in 2000 at a cost of $660 per acre. In 2012, O’Brien began selectively logging this timber tract. In May of 2012, Mount Leno erupted, burying the timberland of O’Brien under a foot of ash. All of the timber on the O’Brien tract was downed. In addition, the logging roads, built at a cost of $150,000, were destroyed, as well as the logging equipment, with a net book value of $309,500.
At the time of the eruption, O’Brien had logged 20% of the estimated 530,000 board feet of timber. Prior to the eruption, O’Brien estimated the land to have a value of $240 per acre after the timber was harvested. O’Brien includes the logging roads in the depletion base.
O’Brien estimates it will take 3 years to salvage the downed timber at a cost of $740,800. The timber can be sold for pulp wood at an estimated price of $3 per board foot. The value of the land is unknown, but must be considered nominal due to future uncertainties.
