Earnings Quality: Accruals vs Operating Cash Flow

Net income and cash from operations differ because US GAAP uses accrual accounting: revenue is recorded when it is earned and expenses when they are incurred, not when cash moves. The difference, called total accruals, takes two lines of any 10-K to compute; a large, growing positive gap (profit running well ahead of cash) is a prompt for questions, not a verdict on a company.

Key takeaways

Total accruals = net income − cash flow from operating activities (CFO); divided by average total assets, it becomes the accruals ratio.
In the illustrative example below, net income rises 38% from year 1 to year 3 while CFO falls 79%, and the accruals ratio moves from −1.8% to +9.1%.
High accruals were linked to less persistent earnings and lower later returns in Sloan (1996); by 2011 those hedge returns were, on average, no longer reliably positive.
CFO can be flattered too: stretched payables, supplier finance, sold receivables and capitalized costs all lift it.

Why profit and cash drift apart

Under accrual accounting, a sale counts as revenue when the company transfers the goods or services, even if the customer pays 60 days later. The revenue standard, ASC 606, ties recognition to the transfer of promised goods or services, in the amount the company expects to be entitled to (FASB, ASU 2014-09). Likewise, a machine's cost is spread over its useful life as depreciation, and a bad-debt provision is booked when a loss is expected, not when the customer defaults.

The statement of cash flows (ASC 230) undoes those timing choices. As the SEC's Beginners' Guide to Financial Statements puts it, the operating section usually reconciles net income to the cash actually received or used, adjusting for non-cash items such as depreciation. This is the indirect method; FASB encourages, but does not require, the direct method of showing gross receipts and payments (ASC 230-10-45-25, as reproduced in ASU 2016-15). Either way, the reconciling lines are where accruals show up:

Reconciling item	Effect on CFO vs net income	Why
Depreciation and amortization	Added back	Expense with no cash outflow in the period; the cash left when the asset was bought
Stock-based compensation	Added back	Employees are paid in shares, not cash
Deferred income taxes	Added back (or subtracted)	Tax expense booked now, paid in a different period
Increase in receivables	Subtracted	Revenue recorded, cash not yet collected
Increase in inventory	Subtracted	Cash spent on goods not yet expensed as cost of sales
Increase in accounts payable	Added	Costs incurred, suppliers not yet paid
Increase in deferred (unearned) revenue	Added	Cash collected before revenue is recognized

Measuring the accrual gap

There are two ways to compute accruals, and they do not always agree.

Cash-flow approach

Total accruals  = Net income − Cash flow from operating activities
Accruals ratio  = Total accruals ÷ Average total assets
Average assets  = (Total assets at start of year + Total assets at end of year) ÷ 2

A positive ratio means reported profit exceeded operating cash; a negative one means the reverse. Scaling by assets allows comparison across years and companies of different size.

Balance-sheet approach

Before the cash flow statement existed in its current form, researchers rebuilt accruals from balance-sheet changes. Sloan (1996), whose data ran from 1962 to 1991, used:

Accruals = (ΔCA − ΔCash) − (ΔCL − ΔSTD − ΔTP) − Dep

ΔCA   = change in current assets
ΔCash = change in cash and cash equivalents
ΔCL   = change in current liabilities
ΔSTD  = change in debt included in current liabilities
ΔTP   = change in income taxes payable
Dep   = depreciation and amortization expense

Sloan scaled by average total assets and used operating income after depreciation, not net income, as earnings. Later studies vary the numerator, denominator and scope, so an accruals ratio quoted without its definition cannot be compared with another.

Hribar and Collins (2002) showed that balance-sheet estimates carry measurement error linked to mergers and acquisitions and discontinued operations. An acquired company's receivables, for example, land on the balance sheet without passing through operating cash flow. For a single company in a year with a deal, the cash-flow approach is the cleaner starting point.

Two examples, computed

Illustrative example: profit up, cash down

A hypothetical manufacturer, in $ millions. Revenue grows 10% a year, payables stay flat at $8 and depreciation is $4 each year. Opening balances (end of year 0): receivables $11, inventory $14, total assets $80.

Line	Year 1	Year 2	Year 3
Revenue	100.0	110.0	121.0
Cost of goods sold	60.0	66.0	73.0
Net income	8.0	9.5	11.0
Receivables, year-end	12.5	17.0	24.0
Inventory, year-end	15.0	19.0	25.0
Total assets, year-end	84.0	93.0	105.0
CFO = NI + 4 − ΔReceivables − ΔInventory	9.5	5.0	2.0
Total accruals = NI − CFO	−1.5	4.5	9.0
Accruals ratio (÷ average assets)	−1.8%	5.1%	9.1%
DSO = receivables ÷ revenue × 365	45.6 days	56.4 days	72.4 days
DIO = inventory ÷ COGS × 365	91.3 days	105.1 days	125.0 days

Year 3 arithmetic: receivables rise by $7 (17 to 24) and inventory by $6 (19 to 25), so CFO = 11 + 4 − 7 − 6 = $2. Accruals = 11 − 2 = $9; average assets = (93 + 105) ÷ 2 = $99; ratio = 9 ÷ 99 = 9.1%. The balance-sheet formula gives the same $9 (7 + 6 − 0 − 4) because no other current item changed.

Over three years the company reports $28.5 million of profit but only $16.5 million of operating cash. Receivables grew 36% and 41% in years 2 and 3 against 10% revenue growth, so DSO (days sales outstanding) rose by about 27 days and DIO (days inventory outstanding) by about 34. Looser credit terms, a slow-paying customer, sales booked ahead of delivery or a planned stock build would all produce this table; only the notes can tell them apart. Both ratios have variants (average balances, 360 days); on average receivables, year 3 DSO would be 61.8 days rather than 72.4, so keep one definition across years.

A filed example: Microsoft, fiscal 2024–2026

The same arithmetic on a large filer's numbers, from the SEC's XBRL company facts for Microsoft (checked October 11, 2026). Fiscal years end June 30; fiscal 2026 is from the 10-K filed July 29, 2026. Microsoft is used only to illustrate the calculation, not as a view on the company.

$ billions	FY2024	FY2025	FY2026
Net income	88.1	101.8	133.7
Cash from operations	118.5	136.2	182.9
Total accruals (NI − CFO)	−30.4	−34.3	−49.2
Average total assets	462.1	565.6	688.7
Accruals ratio	−6.6%	−6.1%	−7.1%

Total assets were $412.0 billion at June 30, 2023, then $512.2 billion, $619.0 billion and $758.4 billion. Accruals are negative in all three years: operating cash exceeded profit. Fiscal 2026 tagged items include depreciation expense of $34.3 billion, stock-based compensation of $12.4 billion and a $9.4 billion rise in unearned revenue, partly offset by a $12.7 billion rise in receivables. Deferred income taxes added $14.4 billion, after reducing CFO in each of the three prior years.

Two cautions. First, the 10-K's management discussion says net gains from investments in OpenAI raised fiscal 2026 net income by $5.0 billion, after net losses that lowered fiscal 2025 net income by $3.6 billion; investment gains and losses are not operating cash, so items like these move the ratio from year to year. Second, a negative ratio is not spare cash. Payments for property and equipment, which ASC 230 places in investing activities, were $115.9 billion in fiscal 2026, so CFO minus that figure is about $67.0 billion, roughly half of net income.

What the research found

Sloan's 1996 paper in The Accounting Review studied 40,679 firm-years of NYSE and AMEX companies. It found that the accrual part of earnings persisted less than the cash part, that stock prices acted as if investors "fixate" on total earnings, and that high-accrual firms had negative, and low-accrual firms positive, future abnormal returns, concentrated around later earnings announcements (Sloan 1996).

Dechow and Dichev (2002) measured accrual quality by how well a company's working-capital accruals map into operating cash flows in the prior, current and next year. Larger estimation errors mean lower quality, and their measure was positively related to earnings persistence.

The return pattern did not last. Green, Hand and Soliman (2011) documented that hedge returns to Sloan's accruals strategy appeared to have decayed in US markets to the point of being, on average, no longer reliably positive. They attribute this in part to more hedge-fund capital exploiting it and, in a weaker role, to a smaller mispricing signal. A high accruals ratio remains a reason to read the notes; the research does not support treating it as a forecast of a stock's return.

Line items that move accruals

When accruals rise, the reconciliation shows which lines did it, and each needs its own check.

Receivables. A rising DSO can reflect customer mix or terms, or revenue recognized early. In 2020 the SEC alleged that Revolution Lighting Technologies recorded anticipated future sales as current "bill and hold" sales to make up revenue shortfalls; the company and four executives agreed to settle without admitting or denying the allegations, subject to court approval (SEC press release 2020-221).
Inventory. Inventory growing faster than cost of goods sold raises DIO and ties cash up in unsold goods. The inventory notes show whether slow-moving stock is being written down.
Capitalized contract costs. ASC 340-40 requires incremental costs of obtaining a contract, such as sales commissions, to be recorded as an asset if the company expects to recover them; a practical expedient allows expensing when the amortization period is one year or less (ASU 2014-09). The commission is still paid from operating cash, so a growing asset balance raises accruals.
Capitalized software. Internal-use software costs are capitalized once set conditions are met; FASB's ASU 2025-06 replaces the project-stage model with a test of committed funding and probable completion, effective for annual periods beginning after December 15, 2027 (early adoption permitted).
Reserves and allowances. Building a reserve lowers profit with no cash; releasing it raises profit with no cash. In April 2022 the SEC found that Rollins Inc. made unsupported reductions to accounting reserves in two quarters, enough to round reported earnings per share up to the next penny; Rollins agreed to an $8 million penalty without admitting or denying the findings (SEC press release 2022-64).
Deferred revenue. This works the other way: prepaid businesses collect cash before recognizing revenue, so a growing balance pushes CFO above net income. If it stops growing, that support fades even if the business is unchanged.

What can flatter operating cash

A low or negative accruals ratio can also come from choices that raise CFO rather than from strong collections.

Stretched payables and supplier finance. Paying suppliers more slowly raises accounts payable and lifts CFO in the year terms lengthen; for a given level of purchases, the lift does not repeat unless terms keep lengthening. Supplier finance programs let suppliers be paid early by a bank while the buyer pays later. Under ASU 2022-04, buyers now disclose the program's key terms, the confirmed amount unpaid, where it sits on the balance sheet and, from fiscal years beginning after December 15, 2023, an annual rollforward; accounting for the obligations is unchanged.
Selling receivables. ASC 230 classifies cash from the collection or sale of customer receivables as operating (ASC 230-10-45-16, in ASU 2016-15). Starting or enlarging a factoring or securitization program therefore pulls collections forward, lowers DSO and raises CFO for that period.
Where costs are classified. Payments for property, plant, equipment and other productive assets are investing outflows under ASC 230-10-45-13. A capitalized cost, such as internal-use software, is therefore usually paid outside CFO, while the same cost expensed would reduce both net income and CFO.
Non-GAAP measures. Under Regulation G, a registrant that publicly discloses a non-GAAP measure, such as adjusted earnings or "free cash flow", must present the most directly comparable GAAP measure with a quantitative reconciliation, and the measure must not be misleading. In filings, Item 10(e) of Regulation S-K also requires the GAAP measure to have equal or greater prominence. The SEC staff warns that tailored accounting, such as accelerating revenue GAAP recognizes over time, can be misleading (Question 100.04).

Frequently asked questions

If CFO is higher than net income, does the company have cash to spare?

Not necessarily: CFO is measured before capital spending. "Free cash flow", usually CFO minus capital expenditures, has no uniform definition; the SEC staff says companies should explain and reconcile it, not imply it is cash free for discretionary use (mandatory debt service, for example, is not deducted) and not present it per share (Question 102.07).

Why is stock-based compensation added back when it is a real cost?

No cash leaves when the expense is booked. The cash cost appears elsewhere: share repurchases, and tax paid when a company withholds shares from an employee's award, are financing outflows under ASC 230-10-45-15 (ASU 2016-15).

Where does a gain on selling a building show up?

The gain is part of net income, but the reconciliation subtracts it, and the full sale proceeds appear in investing activities. FASB's illustrative statement pairs "gain on sale of facility" in the reconciliation with "proceeds from sale of facility" under investing (ASU 2016-15, Example 1). A large one-off gain therefore widens the accrual gap for that year.

Did ASC 606 change how much cash companies collect?

Not by itself. The standard governs when and how much revenue is recognized, not when customers pay (ASU 2014-09). A timing change moves net income and balances such as receivables and deferred revenue while cash stays the same, so it shows up in accruals.

How can the same numbers be pulled for another company?

The SEC publishes each filer's tagged data at data.sec.gov in the format of the company facts file used above, with the 10-digit CIK in the address. Look for NetIncomeLoss, NetCashProvidedByUsedInOperatingActivities and Assets; each value carries its period, form type and filing date, which separates 10-K from quarterly values. Some companies use custom tags, so check totals against the filing.
