Matching Concept is based on the accounting period concept. The paramount object of running a business is to earn profit. In order to ascertain the profit made by the business during a period, it is necessary that “revenues” of the period should be matched with the costs (expenses) of that period. In other words, income made by the business during a period can be measured only with the revenue earned during a period is compared with the expenditure incurred for earning that revenue. However, in cases of mergers and acquisitions, companies sometimes undertake to defer revenue expenditure over future years which brings in the concept of Deferred Tax Accounting. Therefore, today it cannot be said that the concept of accrual is limited to one year. It is a principle of recognizing costs (expenses) against revenues or against the relevant time period in order to determine the periodic income. This principle is an important component of accrual basis of accounting. As stated above, the object of AS 22 is to reconcile the matching principle with the Fair Valuation Principles. It may be noted that recognition, measurement and disclosure of various items of income, expenses, assets and liabilities is done only by Accounting Standards and not by provisions of the Companies Act
