2. The estimating of income under conditions of uncertainty as well of certainty requires that the accountant trace carefully the relation between cash movements and income flows. While it is true that there may not be an equality between the amount of revenue and that amount of cash received for any period less than the duration of enterprise existence, receipt are the elements with which we construct all measures of revenue. A dollar is received at some time during the life of the enterprise for each dollar of revenue exhibited during the fiscal period. The sum of the annual revenues for all fiscal period is equal to the amount of the ultimate total revenue. There may be no equality between the amount of expense and the amount of cash disbursements for the fiscal period yet, the two sums are equal for the life of the enterprise. A dollar is disbursed at sometime during the enterprise existence for each dollar exhibited as expense of the fiscal period. The accountant's problem is essentially one of reconciling cash receipts with revenues with cash disbursements with expenses. That is, for every revenue recognized but not received in cash during the current period, an asset of equal value must be recorded (or a liability must be amortized); for every expense recognized but not paid in cash in the current period, a liability of equal value must be recognized but not paid in cash in the current period, a liability of equal value must be recognized (or an asset must be amortized).
