Response the following questions related to a company's activities for the current year:
1. After using an expected useful life of 20 years and no salvage value to depreciate its office equipment over the preceding 15 years, the company decided early this year that the equipment will last only two more years. How should the effects of this decision be reported in the current year financial statements?
2. A review of the notes payable files discovers that two years ago the company reported the entire amount of a payment (principal and interest) on an installment note payable as interest expense. This mistake had a material effect on the amount of income in that year. How should the correction be reported in the current year financial statements?
