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.
Depreciation expense records the value of depreciation that has been moved from the balance sheet and onto the income statement during the period. When fixed assets depreciate, a journal entry is made to credit, or increase, the amount of accumulated depreciation associated with the fixed asset. Simultaneously, an equivalent debit is made to increase the amount of depreciation expense for the period.
