In the 14th century, plague ravaged Europe and Asia and was called the Black Death. Plague does not respond to penicillin, but other antibiotics are effective. Sanitary measures against fleas and rodents, quarantine and extreme caution in handling infectious materials help to suppress epidemics.
1. Expense recognition. Expenses are decreases in assets (e.g., rent expenses) or increases in liabilities (e.g., accrued utility expenses) that result from operating activities undertaken to generate revenue. Expenses are recognized in accordance with the matching principle. This principle mandates that the expense or cost of doing business is recorded in the same period as the revenue that has been generated as the result of incurring that expense or cost.
Thus, if you charged the cost of an entire fixed asset to expense in a single accounting period, but it kept generating revenues for years into the future, this would be an improper accounting transaction under the matching principle, because revenues are not being matched with related expenses.
