What Is Operating Cash Flow?

Operating cash flow (OCF), also known as cash flow from operating activities, represents the amount of cash a company generates from its normal business operations. It is a crucial component of a company's cash flow statement, a key financial statements document that falls under the broader category of financial accounting. This metric indicates a company's ability to generate sufficient positive cash flow to maintain and grow its operations, rather than relying on external financing or asset sales. Operating cash flow specifically includes the cash generated from selling goods and services and the cash spent on daily business activities, such as salaries, rent, and utilities.

History and Origin

While concepts related to cash flow have existed for centuries, the formal requirement for a statement of cash flows, which includes operating cash flow, is a relatively modern development in financial reporting. Early forms of financial reporting, such as those used by the Northern Central Railroad in 1863, included summaries of cash receipts and disbursements.⁶ However, for many years, financial statements primarily focused on the income statement and balance sheet.⁵

In 1971, the Accounting Principles Board (APB) issued Opinion No. 19, mandating a "funds statement" to be included in annual reports, although it did not standardize the definition of "funds" or the format.⁴,³ This led to inconsistencies, with many companies reporting changes in working capital rather than focusing on cash.² The Financial Accounting Standards Board (FASB) eventually superseded this in November 1987 with Statement No. 95, which formally required the statement of cash flows and provided a standardized format, including the classification of activities into operating, investing, and financing. This historical shift significantly enhanced transparency regarding a company's true cash generation.¹

Key Takeaways

• Operating cash flow measures the cash generated by a company's core business activities.
• It is a strong indicator of a company's financial health and sustainability.
• OCF excludes non-cash expenses like depreciation and amortization, providing a clearer picture of cash profitability.
• Positive operating cash flow is essential for a company to fund its operations, invest in growth, and repay debts without needing to raise additional capital.
• Analysts often use operating cash flow to assess a company's liquidity and overall profitability.

Formula and Calculation

Operating cash flow can be calculated using two primary methods: the direct method and the indirect method. Most companies use the indirect method, which starts with net income and adjusts it for non-cash items and changes in working capital.

Indirect Method Formula:

Where:

• Net Income: The profit or loss for the period, found on the income statement.
• Non-Cash Expenses: Expenses such as depreciation, amortization, and depletion that reduce net income but do not involve an outflow of cash.
• Non-Operating Gains/Losses: Gains or losses from activities outside of core operations (e.g., sale of an asset) that impact net income but are classified under investing or financing activities on the cash flow statement.
• Changes in Working Capital Accounts:
  • Increase in Current Assets (e.g., accounts receivable): Subtract from net income, as cash was used or not yet received.
  • Decrease in Current Assets: Add to net income, as cash was received.
  • Increase in Current Liabilities (e.g., accounts payable): Add to net income, as an expense was incurred but cash was not yet paid.
  • Decrease in Current Liabilities: Subtract from net income, as cash was paid out.

Interpreting the Operating Cash Flow

A company's operating cash flow provides crucial insights into its operational efficiency and financial health. A consistently positive operating cash flow indicates that the business is generating enough cash from its primary activities to cover its day-to-day costs. This is a sign of a healthy and sustainable business model. Investors often look for increasing trends in operating cash flow, as it suggests growing core business strength.

Conversely, a declining or negative operating cash flow can signal underlying problems, such as decreasing revenue, rising expenses, or inefficient management of working capital. While a single period of negative OCF might be explainable (e.g., a large inventory build-up), sustained negative operating cash flow can indicate that a company may struggle to meet its obligations or fund future growth without external financing.

Hypothetical Example

Consider a hypothetical company, "GreenThumb Landscaping," which reports the following for a given quarter:

• Net Income: $50,000
• Depreciation Expense: $10,000
• Increase in Accounts Receivable: $5,000
• Increase in Accounts Payable: $3,000

To calculate GreenThumb's operating cash flow using the indirect method:

1. Start with Net Income: $50,000
2. Add back Depreciation (a non-cash expense): + $10,000
3. Subtract the Increase in Accounts Receivable (cash not yet collected): - $5,000
4. Add the Increase in Accounts Payable (expense incurred, but cash not yet paid): + $3,000

Operating Cash Flow = $50,000 + $10,000 - $5,000 + $3,000 = $58,000

This $58,000 in operating cash flow shows that GreenThumb's core business generated a healthy amount of cash, even after accounting for non-cash items and changes in its current assets and liabilities.

Practical Applications

Operating cash flow is widely used by investors, analysts, and creditors for various real-world applications:

• Valuation Analysis: Analysts use OCF as a building block for calculating metrics like free cash flow, which is critical for valuing a company using discounted cash flow (DCF) models.
• Creditworthiness Assessment: Lenders evaluate a company's ability to generate sufficient operating cash flow to repay its debts. A strong OCF indicates lower default risk.
• Performance Evaluation: Comparing operating cash flow to net income helps assess the quality of earnings. A large disparity might suggest aggressive accounting practices or significant non-cash items impacting profitability.
• Investment Decisions: Investors often prioritize companies with robust and consistent operating cash flow, as it signifies self-sufficiency and the potential for sustainable growth and shareholder returns.
• Regulatory Filings: Publicly traded companies are required to report their operating cash flow as part of their cash flow statements in filings with regulatory bodies like the U.S. Securities and Exchange Commission (SEC). The SEC's EDGAR database provides free public access to these corporate filings, allowing investors to research a company's financial information, including its operating cash flow data. For example, financial statements for companies like the New York Times Company's cash flow data are publicly available.

Limitations and Criticisms

While operating cash flow is a vital metric, it is not without limitations:

• Timing Differences: OCF can be affected by the timing of cash receipts and payments. For instance, a company might delay paying its suppliers to temporarily boost its operating cash flow, which isn't sustainable long-term.
• Capital Expenditures: Operating cash flow does not account for the cash required for capital expenditures (CapEx), which are necessary investments in property, plant, and equipment to maintain or grow the business. A high OCF might seem impressive, but if the company is not spending enough on CapEx, its long-term viability could be at risk. This is why analysts often look at free cash flow.
• Quality of Earnings: Although OCF helps assess earnings quality, it doesn't reveal the specific drivers of cash flow changes. An increase in operating cash flow due to a significant decrease in inventory might not be sustainable if it signals declining demand.
• Classification Issues: The classification of certain cash flows into operating, investing, or financing activities can sometimes be a source of confusion or misinterpretation, although the FASB provides guidelines. The SEC has provided SEC staff observations regarding common reporting deficiencies and the importance of high-quality cash flow information for investors, highlighting the need for careful preparation and review.

Operating Cash Flow vs. Net Income

Operating cash flow and net income are both critical measures of a company's financial performance, but they represent different aspects. Net income, found on the income statement, reflects a company's profitability based on the accrual accounting method. This means it includes non-cash items like depreciation and recognizes revenue when earned and expenses when incurred, regardless of when cash changes hands.

While net income can be influenced by accounting estimates and non-cash entries, operating cash flow provides a more tangible view of the cash flowing into and out of the business from its core activities. A company can have high net income but low or negative operating cash flow if it sells on credit and struggles to collect receivables, highlighting why both metrics are essential for a comprehensive financial analysis.

FAQs

What is considered a good operating cash flow?

A good operating cash flow is generally positive and consistently increasing over time. It indicates that a company is generating enough cash from its primary business activities to cover its costs and potentially fund growth or reduce debt. The specific amount considered "good" often depends on the industry, company size, and stage of development.

How is operating cash flow different from free cash flow?

Operating cash flow represents the cash generated by core business operations. Free cash flow (FCF) takes OCF a step further by subtracting capital expenditures (CapEx). FCF is the cash a company has left after paying for its day-to-day operations and necessary investments to maintain or expand its asset base. It is the cash available to distribute to investors or pay down debt.

Why is operating cash flow important for investors?

Operating cash flow is important for investors because it provides a realistic view of a company's financial health and its ability to sustain itself. It shows how much cash a business is truly generating from its primary operations, independent of non-cash accounting entries or financing decisions. Strong OCF indicates a company's capacity to pay dividends, reduce debt, and fund future growth, contributing to long-term value creation.

Can a company have negative operating cash flow?

Yes, a company can have negative operating cash flow. This means that its core business activities are consuming more cash than they are generating. While a temporary negative OCF might occur due to significant investments in inventory or a delay in collecting accounts receivable, prolonged negative operating cash flow is a red flag, indicating potential financial distress or an unsustainable business model that may require external financing to continue operations.
