FuturePetro Corp. owned the following unproved property as of the end of 1986.

Significant Leases		Insignificant Leases
Lease S	$510,000	Lease T	$85,000
Lease U	$320,000	Lease V	$50,000
Total	$830,000	Lease W	$45,000
		Lease X	$40,000
		Total	$220,000

Although no activity took place on Lease S during the year, FuturePetro decided that Lease S was not impaired because there were still three years left in that lease’s primary term. Two dry holes were drilled on Lease U during the year; but because FuturePetro intended to drill one more well on Lease U in the coming year, it decided that Lease U was only 55% impaired. With respect to the insignificant leases, past experience indicates that 70% of all unproved properties assessed on a group basis will eventually be abandoned. FuturePetro’s policy is to provide at year-end an allowance equal to 65% of the gross cost of these properties. The allowance account had a balance of $24,000 at year end. Give the entries to record impairment, prepare the adjusted trial balance, and calculate the deferred tax liability.
