The balance sheet should disclose a company’s wealth at a point in time. Wealth is defined as the present value of all resources less the present value of all obligations. Although the use of present-value measurements in accounting is increasing, it is not used extensively for all assets and liabilities. As a result, a variety of methods are currently being used to measure changes in the individual components of the elements of the balance sheet. These measurements can be summarizes as part oriented-historical; current oriented-replacement amounts; and future oriented-expected amounts.
