Cookie jar accounting
（重定向自Cookie jar reserves）
Cookie jar accounting or cookie jar reserves is an accounting practice in which a company uses generous reserves from good years against losses that might be incurred in bad years.
An example of a cookie jar reserve is a liability created when a company records an expense that is not directly linked to a specific accounting period -- the expense may fall in one period or another. Companies may record such discretionary expense when profits are high because they can afford to take the hit to income. When profits are low, the company reduces the liability (the reserve) rather than recording an expense in the lean year.
