The operating cycle measures the average length of time to invest cash in inventory, convert the inventory to accounts receivable, and collect the receivables.
Thus, for Clay, its operating cycle is the sum of its number of days’ sales in inventory plus the number of days’ sales in trade accounts receivable, or 61 days + 33 days = 94 days.
Basically, this measures the number of days to go from cash through inventory and accounts receivable, back to cash.
