If the normal collection interval of a receivables is longer than a year (such as with longer term installment receivables), then their inclusion as current assets is proper provided the operating cycle is equal to or greater than the obligation due date for the receivables. Similarly, if inventories, by business need or custom, have to be kept on average for more than 12 months, then this normal inventory holding period becomes part of the operating cycle and such inventories are included among current assets.
