the balance sheet pending amortization. Deferred charges often extend over five years or more and occur infrequently unlike prepaid expenses, e.g. insurance, interest, rent. Financial ratios are based on the total assets excluding deferred charges since they have no physical substance (cash realization) and cannot be used in reducing total liabilities. Deferred expense A Deferred expense or prepayment, prepaid expense, plural often prepaids, is an asset representing cash paid out to a counterpart for goods or services to be received in a later accounting period. For example, if a service contract is paid quarterly in advance, at the end of the first month of the period two months remain as a deferred expense. In the deferred expense the early payment is accompanied by a related recognized expense in the subsequent accounting period, and the same amount is deducted from the prepayment. The deferred expense shares characteristics with accrued revenue (or accrued assets) with the difference that an asset to be covered later are proceeds from a delivery of goods or services, at which such income item is earned and the related revenue item is recognized, while cash for them is to be received in a later period, when its amount is deducted from accrued revenues. For example, when the accounting periods are monthly, an 11/12 portion of an annually paid insurance cost is added to prepaid expenses, which are decreased by 1/12 of the cost in each subsequent period when the same fraction is recognized as an expense, rather than all in the month in which such cost is billed. The not-yet-recognized portion of such costs remains as prepayments (assets) to prevent such cost from turning into a fictitious loss in the monthly period it is billed, and into a fictitious profit in any other monthly period. Similarly, cash paid out for (the cost of) goods and services not received by the end of the accounting period is added to the prepayments to prevent it from turning into a fictitious loss in the period cash was paid out, and into a fictitious profit in the period of their reception. Such cost is not recognized in the income statement (profit and loss or P&L) as the expense incurred in the period of payment, but in the period of their reception when such costs are recognized as expenses in P&L and deducted from prepayments (assets) on balance sheets.
