Depreciation and the matching principle
Depreciation expense reduces an accounting period’s income even though the expense does not require a cash or credit payment. The reason for the expense is to comply with the matching principle required by accrual accounting. According to the principle, expenses are recognized regardless of cash payment when obligations are:
1. Incurred (usually when goods are transferred (sold) or services rendered),
2. Generated by expenses involved in the earning of the accounting period’s revenues.
