Introduction
Amazon reported a net loss of $2.7 billion for 2022. Its operations generated $46.8 billion of cash the same year. Most of the difference came from three lines at the top of the cash flow statement in its annual report: $41.9 billion of depreciation and amortization, $19.6 billion of stock-based compensation and $17.0 billion of non-operating expense, mostly a $12.7 billion loss on the value of its stake in the electric vehicle maker Rivian. None of them involved cash leaving the company that year, yet all of them reduced net income. A fourth line, deferred taxes, ran the other way: an $8.1 billion tax benefit had lifted net income without bringing in any cash, so it was deducted.
These are non-cash items: charges and credits in net income that did not move cash in the period. The cash flow statement reverses them so that operating cash flow reflects what actually happened to cash. Understanding each one, what it represents, where its cash effect really sits and whether it will recur, is essential to judging how much of a company's operating cash flow is genuine and sustainable.
Why Non-Cash Items Appear in the Reconciliation
Under the indirect method described in cash flow from operations, operating cash flow starts from net income and adjusts it, and Accounting Standards Codification (ASC) 230 requires each major class of adjustment to be shown separately. Non-cash items fall into three groups:
- Allocations of past spending: depreciation and amortization spread the cost of assets bought in earlier periods, whose cash appeared in investing activities when they were bought.
- Expenses settled in something other than cash: stock-based compensation is paid in shares; deferred tax expense will be paid in a later period; accrued interest on payment-in-kind debt is added to the principal.
- Gains and losses on value changes: impairments, unrealized investment gains and losses and gains on sales change net income without changing operating cash.
- Non-cash charge
An expense recorded in net income that does not require a cash payment in the period, such as depreciation, amortization, stock-based compensation, impairments or deferred tax expense. It is added back to net income when calculating operating cash flow under the indirect method.
Amazon's reconciliation shows how large these items can be, and how much they can vary from year to year:
| Line item | 2022 | 2024 |
|---|---|---|
| Net income (loss) | (2,722) | 59,248 |
| Depreciation and amortization, including capitalized content and lease assets | 41,921 | 52,795 |
| Stock-based compensation | 19,621 | 22,011 |
| Non-operating expense (income), net | 16,966 | 2,012 |
| Deferred income taxes | (8,148) | (4,648) |
| Net income adjusted for non-cash items | 67,638 | 131,418 |
| Changes in operating assets and liabilities | (20,886) | (15,541) |
| Net cash provided by operating activities | 46,752 | 115,877 |
Source: Amazon 2024 annual report. Non-operating expense in 2022 mainly reflects valuation losses on marketable equity securities, including a $12.7 billion loss on its Rivian investment.
In 2022, the non-operating add-back alone was larger than the net loss, because a market-value decline on an investment had been charged to earnings without any cash leaving. By 2024, with net income at $59.2 billion, the same line had shrunk to $2.0 billion. The recurring add-backs, depreciation and stock compensation, were large in both years.
The Main Non-Cash Charges
Depreciation and Amortization
The largest add-back for most companies is depreciation and amortization. Its cash cost was paid when the assets were purchased, as capital expenditure in investing activities, so adding it back avoids counting the cost twice. Amazon's line also includes the amortization of capitalized video and music content, a reminder that the label can cover more than plant and equipment; US GAAP places the cash paid for that content in operating activities rather than capital expenditure. The add-back is recurring, but it is not free cash: a business that does not keep spending on capital expenditure eventually loses the assets that generate its revenue. How depreciation moves through all three statements is traced in depreciation on the three statements.
Stock-Based Compensation
Stock-based compensation is added back because employees were paid in shares, not cash. Economically, though, the cost is real and recurring, borne by shareholders through dilution or through the buybacks that offset it. Research summarized on Columbia Law School's blog on stock-based compensation and analysts' valuations found that average stock-based compensation rose from 2.6% to 3.8% of operating expenses for public companies between fiscal 2006 and 2018, and that analysts who exclude it from their discounted cash flow models issue more optimistic price targets than those who treat it as an expense. The accounting for these awards is covered in stock-based compensation accounting.
Impairments and Write-Downs
Impairments of goodwill, intangibles, property and inventory reduce net income and are added back in full, since they record a loss in value rather than a payment. They are usually non-recurring, so they distort a single year's earnings far more than its cash flow. A company reporting a large loss because of an impairment can therefore show healthy operating cash flow in the same year, as the cash cost of the impaired asset was paid when the asset was acquired.
Deferred Income Taxes
The deferred tax line adjusts total tax expense to the tax currently owed for the year, which is close to the tax paid in cash (any timing gap in payment sits in working capital). A positive add-back means tax expense exceeded cash taxes, typically because tax depreciation is running ahead of book depreciation and taxes are being deferred. A negative line, as at Amazon, means cash taxes exceeded the tax expense recorded, often because expenses already recorded in the books are not yet deductible for tax. The mechanics are covered in deferred tax liabilities.
Interest-Related Items
Two smaller items affect interest. The amortization of debt discounts and issuance costs increases interest expense without any extra cash payment, and is added back. Payment-in-kind interest, common in private credit and leveraged structures, is added to the loan balance instead of being paid, so it reduces net income and is added back as a non-cash item; the cash is paid only when the debt is repaid. For highly leveraged companies, these items can make reported interest expense much higher than cash interest, which matters for coverage ratios built on cash.
Non-Cash Gains and Losses
The reconciliation also removes gains and adds back losses that did not affect operating cash in the period:
- Unrealized investment gains and losses: changes in the fair value of equity securities, such as Amazon's Rivian stake, pass through net income but involve no cash until the shares are sold.
- Gains and losses on asset sales: the proceeds appear in investing activities, so the accounting gain or loss is reversed.
- Gains and losses on debt extinguishment: the cash paid to retire debt sits in financing activities.
- Equity method income: a share of an affiliate's profit is non-cash; only dividends received are cash.
- Unrealized gain or loss
A change in the fair value of an asset or liability that the company still holds, recognized in net income or other comprehensive income but not yet converted into cash by a sale or settlement. Unrealized gains and losses recorded in net income are reversed in operating cash flow.
These items can be large and volatile, as Amazon's swing from a $17.0 billion add-back in 2022 to $2.0 billion in 2024 shows. They are also the items most likely to make net income a poor guide to operating performance, which is why bankers usually remove them from normalized earnings as well as from operating cash flow.
How Bankers Read the Non-Cash Lines
Bankers sort non-cash items into those that reflect a recurring economic cost and those that are genuinely one-off:
- Recurring and economically real: depreciation, which must eventually be matched by capital expenditure, and stock-based compensation, which is paid every year in shares.
- Recurring but potentially reversing: deferred taxes, which depend on continued investment and current tax law.
- One-off or volatile: impairments, unrealized investment gains and losses, and gains on sales.
The distinction matters most for free cash flow. Operating cash flow that is high because of large stock-based compensation add-backs overstates the cash a business would generate if it paid its employees in cash, and operating cash flow lifted by deferred tax add-backs may not last. Many bankers deduct stock-based compensation, or the cash spent on buybacks to offset dilution, when comparing free cash flow across companies, as discussed in free cash flow definitions.
Non-cash items are not adjustments to be skimmed past on the way to the operating cash flow total. They explain why a company's earnings and its cash diverged, and they show which part of that divergence is a lasting feature of the business and which part will not come back. Where these lines sit within the full statement is shown in how the cash flow statement works.
