Final answer:
Based on the given information, the non-current deferred tax asset reported on Apple's December 31, Year 6 balance sheet under U.S. GAAP would be $160,000.
Step-by-step explanation:
Under U.S. GAAP, a non-current deferred tax asset is reported for the portion of deferred tax assets that are not expected to be realized within the next year. In this case, the NOL carryforward of $200,000 is the only item that is expected to be realized in Year 7. Therefore, the non-current deferred tax asset reported on Apple's December 31, Year 6 balance sheet would be $160,000, which is the sum of the deferred tax assets for the accelerated tax depreciation and the warranty expense.
