Spamela Hamderson Inc. reports the following pretax income (loss) for both financial reporting purposes and tax purposes. (Assume the carryback provision is used for a net operating loss.)

                                             

The tax rates listed were all enacted by the beginning of 2012.

Instructions
  (a) Prepare the journal entries for the years 2012–2015 to record income tax expense (benefit) and income taxes payable (refundable) and the tax effects of the loss carryback and carryforward, assuming that at the end of 2014 the benefits of the loss carryforward are judged more likely than not to be realized in the future.
  (b) Using the assumption in (a), prepare the income tax section of the 2014 income statement beginning with the line “Operating loss before income taxes.”
  (c) Prepare the journal entries for 2014 and 2015, assuming that based on the weight of available evidence, it is more likely than not that one-fourth of the benefits of the loss carryforward will not be realized.
  (d) Using the assumption in (c), prepare the income tax section of the 2014 income statement beginning with the line “Operating loss before income taxes.”
