Most accounting-related errors are detected and corrected in the current period. Of those that go undetected, some will fix themselves over two periods, while other errors may remain undetected for years. What is difference between those errors that will counterbalance and those that carry over from period to period? Identify these differences considering such issues as whether the accounts involved are balance sheet and/ or income statement accounts, whether they are current and/ or noncurrent accounts, and whether they involve revenue or expense accounts. Finally, provide a systematic method for analyzing an error to determine if it counterbalances or if a journal entry is necessary to correct the books.
