Accrued liabilities and accrued expenses explained

Harbor Services Group, a national facilities-management contractor, closed fiscal 2025 with 11.2% net margin and beat EPS guidance by four cents. The cash flow statement told a different story: operating cash flow (CFO) was negative $6M in Q4 despite $42M of quarterly net income. Finance traced the gap to $19M of accrued liabilities booked in December — year-end bonuses, warranty true-ups on a municipal contract, and a litigation reserve — that reduced earnings on paper but had not yet been paid in cash. When January payroll and legal settlements hit, accrued liabilities fell and CFO normalized. Investors who had only watched the income statement were surprised by the working-capital swing.

Accrued liabilities (often called accrued expenses) are balance sheet obligations for goods or services already received or obligations already incurred, where cash payment happens later. They are the mirror image of deferred revenue: deferred revenue is cash received before revenue is earned; accrued liabilities are expenses recognized before cash is paid. This guide covers common accrual categories, journal-entry mechanics, how accruals flow through the indirect-method CFO bridge, links to earnings quality and working capital, the Harbor Services refactor, a decision table versus net income alone, pitfalls, and an investor checklist.

What accrued liabilities represent

Under accrual accounting (GAAP and IFRS), expenses are matched to the period in which the economic benefit is consumed — not necessarily when cash leaves the bank. When a company incurs a cost but has not yet paid, it records:

Debit: expense (income statement)
Credit: accrued liability (balance sheet)

The liability sits in current liabilities (or non-current for long-dated obligations) until settlement. On payment, the company debits the accrued liability and credits cash. No second expense hit occurs if the original accrual was correct.

Accrued liabilities differ from accounts payable, which usually arise from vendor invoices for goods received. Accruals often cover estimates where no invoice exists yet: employee bonuses earned in December but paid in February, interest on debt between coupon dates, or warranty costs expected from units shipped in the quarter.

Common categories investors see in filings

Payroll, bonuses, and benefits

Wages earned but unpaid at period-end, vacation accruals, and performance bonuses estimated before board approval are classic accrued expenses. Q4 spikes are common in services and asset-light businesses.

Interest and taxes

Coupon interest accrues daily between payment dates. Income tax accruals bridge estimated quarterly provisions to final returns. Large swings near year-end can move CFO without changing operating margin.

Warranty, returns, and litigation

Product companies accrue warranty reserves as a percentage of revenue. Litigation and environmental reserves are re-estimated each quarter. Increases hit the income statement immediately; cash may trail by years.

Utilities, rent, and subcontractor costs

Contractors like Harbor Services accrue subcontractor work completed before invoice receipt. Utilities billed in arrears follow the same pattern.

In 10-K and 10-Q filings, accrued liabilities often appear as a single line with detail in footnotes. Compare the line item quarter-over-quarter and read the “accrued expenses” or “other current liabilities” disclosure for composition changes.

How accruals affect the CFO bridge

The indirect method starts with net income and adjusts for non-cash items and working capital changes. An increase in accrued liabilities means expenses reduced net income but cash was not yet paid — so CFO adds the increase back. A decrease (payment of prior accruals) subtracts from CFO even if current-period earnings look strong.

This is why Harbor Services showed positive net income and negative Q4 CFO: December bonus and warranty accruals inflated the liability balance (helpful to future CFO when reversed), but concurrent receivable growth and inventory builds overwhelmed the add-back in that quarter. The following quarter, bonus cash payments reduced accrued liabilities and dragged on CFO while net income looked cleaner — a pattern credit analysts watch closely.

Accrued liabilities are part of working capital when classified as current. They are not always in the standard “current assets minus current liabilities” quick ratio, but they matter for cash conversion analysis alongside receivables and payables.

Accruals and earnings quality

Accrual accounting enables useful matching, but it also creates discretion. Management can smooth earnings by raising or lowering reserves within GAAP bounds. Red flags include:

Net income rising while total accruals rise faster than revenue — profits may be overstated relative to cash economics.
Repeated “one-time” reserve releases boosting earnings without operational improvement.
Large year-end accrual reversals in Q1 that were not disclosed as changes in estimate.
CFO persistently below net income while accrued liabilities flatten or fall — prior accruals may have been aggressive.

The Sloan accrual ratio and CFO-to-net-income conversion metrics (covered in earnings quality and FCF conversion guides) help separate sustainable cash earnings from accrual-heavy reporting.

Harbor Services: separating real margin from accrual timing

After the Q4 surprise, Harbor Services finance rebuilt a monthly accrual waterfall:

Bonus accrual policy tied to trailing operating margin, with monthly true-ups instead of a single December spike.
Warranty reserve linked to defect telemetry from field service tickets rather than flat revenue percentages.
Litigation accrual gated by outside counsel probability bands with board pre-approval above $2M.
Investor reporting added accrued-liability bridge slides to earnings decks alongside CFO walk.

Over the next four quarters, Q4 CFO volatility narrowed from a $48M swing (peak-to-trough vs net income) to $11M, and the stock's earnings-reaction beta fell as analysts could model bonus and warranty cash timing explicitly.

Technique decision table

Question	Best approach	Why not the alternative?
Did the company earn cash profits this quarter?	CFO and FCF	Net income includes unpaid accrual expenses
What obligations are due soon without invoices?	Accrued liabilities footnotes	Accounts payable misses bonuses and reserves
Is earnings growth sustainable?	CFO / net income trend + accrual ratio	Margin alone ignores accrual reversals
Year-end earnings beat quality?	Accrued liability Δ vs revenue Δ	EPS beat can be accrual-driven
Cash timing next quarter?	Scheduled bonus/tax payment calendar	Balance sheet snapshot lacks payment dates
Peer comparison on reserves?	Warranty % of revenue, normalized	Absolute accrual dollars ignore scale

Common pitfalls

Treating all liability increases as good for CFO — deferred revenue and customer deposits are different animals with opposite economic meaning.
Ignoring offsetting receivable builds — accrual add-backs can be wiped out by working capital drains in the same quarter.
Annualizing one quarter with seasonal accruals — retail and services Q4 bonus accruals distort trailing metrics.
Confusing accrued expenses with contingent liabilities — some legal exposures are disclosed but not accrued until probable and estimable.
Missing reclassifications — companies sometimes move items between AP, accrued liabilities, and other current liabilities.
Using EBITDA instead of CFO — EBITDA adds back D&A but not the cash timing of accrual payments.

Investor checklist

Locate accrued liabilities / accrued expenses on the balance sheet.
Read footnotes for bonus, warranty, tax, and litigation components.
Compute quarter-over-quarter and year-over-year change in total accruals.
Walk the indirect CFO bridge; isolate accrued-liability line in WC adjustments.
Compare CFO to net income over at least eight quarters.
Flag Q4 accrual spikes and model cash payment in Q1.
Cross-check warranty rates against peers on a revenue-normalized basis.
Review earnings-quality metrics when accruals grow faster than sales.
Verify contingent liability disclosures for unaccrued tail risks.
Track management's accrual policy changes in MD&A.

Key takeaways

Accrued liabilities are expenses recognized before cash is paid — the expense side counterpart to deferred revenue.
Increases in accrued liabilities add back to CFO under the indirect method; decreases subtract when cash settles prior obligations.
Year-end bonus, warranty, and litigation accruals are frequent sources of net-income vs CFO divergence.
Harbor Services cut Q4 CFO volatility by monthly accrual true-ups and transparent investor bridges.
Persistent gaps between earnings and cash warrant earnings-quality review, not dismissal as timing noise.
