When management does not provide reasonable justification that a change in accounting principle is preferable and it presents comparative financial statements, the auditor should express a qualified opinion

  1. Only in the year of the accounting principle change.
  2. Each year that the financial statements initially reflecting the change are presented.
  3. Each year until management changes back to the accounting principle formerly used.
  4. Only if the change is to an accounting principle that is not generally accepted.
