The operating cash flows component of the cash flow statement refers to all cash flows that have to do with the actual operations of the business. It refers to the amount of cash a company generates from the revenues it brings in, excluding costs associated with long-term investment on capital items or investment in securities (these are investing or financing activities). Essentially, it is the difference between the cash generated from customers and the cash paid to suppliers.
Cash flows from operating activities can be calculated and disclosed on the cash flow statement using the direct or indirect method. The direct method shows the cash inflows and outflows affecting all current asset and liability accounts, which largely make up most of the current operations of the entity. Those preparers that use the direct method must also provide operating cash flows under the indirect method. The indirect method is a reconciliation of the period's net income to arrive at cash flows from operations; changes in current asset and liability accounts are added or subtracted from net income based on whether the change increased or decreased cash. The indirect method must be disclosed in the cash flow statement to comply with U.S. accounting standards, or GAAP.
US GAAP vs. IFRS Cash Flow Classification
Some transactions may be classified as different types of cash flows under GAAP and IFRS accounting standards.
One major difference between GAAP and IFRS is how interest paid is categorized. Under GAAP, a loan payment would have to be broken down into two parts: the payment on principal (financing) and the payment of interest (operating). Under IFRS, it is possible to categorize both as financing cash flows.
All of the major operating cash flows, however, are classified the same way under GAAP and IFRS. The most noticeable cash inflow is cash paid by customers. Cash from customers is not necessarily the same as revenue, though. For example, if a company makes all of its sales by extending credit to customers, it will have generated revenues but not cash flows from customers. It is only when the company collects cash from customers that it has a cash flow.
Significant cash outflows are salaries paid to employees and purchases of supplies. Just as with sales, salaries, and the purchase of supplies may appear on the income statement before appearing on the cash flow statement. Operating cash flows, like financing and investing cash flows, are only accrued when cash actually changes hands, not when the deal is made.
