Evaluating Quality of Financial Reports: formula sheet

Key formulas

High-quality earnings test

High-quality earnings = sustainable + provide an adequate return (above cost of capital)

Both conditions are needed. Sustainable but low earnings are still lower quality.

Decision-useful report test

Decision-useful = relevant + faithful representation (complete, neutral, free from error)

Reporting quality is judged on this, not on whether profit is high.

Spectrum order (best to worst)

High-quality reporting and earnings > high-quality reporting, lower-quality earnings > compliant but biased > compliant but earnings managed > non-compliant > fictitious (fraud)

Know the ordering and the dividing line: fraud is the extreme end.

Dependency rule

High reporting quality is necessary, but not sufficient, for high earnings quality

Low reporting quality makes earnings quality difficult and unreliable to assess.

Definition of high-quality earnings

High-quality earnings = sustainable earnings + adequate return on invested capital

Both parts are needed. Sustainable but low returns, or high but unsustainable earnings, are lower quality.

Sustainable (core) earnings, adjusted

Core earnings = Reported net income − non-recurring gains + non-recurring losses (each after tax)

Adjust after tax. Remove one-off gains and add back one-off charges, if they are truly non-recurring.

Accruals ratio (balance sheet approach)

Aggregate accruals = Change in net operating assets; Accruals ratio = Aggregate accruals ÷ Average net operating assets

A higher ratio suggests more of earnings comes from accruals rather than cash, which is a warning sign for persistence.

Cash flow comparison

Accruals = Net income − Cash flow from operations; Cash-flow-based accruals ratio = (Net income − Cash flow from operations) ÷ Average net operating assets

Persistently large positive accruals relative to average net operating assets point to lower earnings quality.

Aggressive choice direction

Aggressive: current earnings ↑ or assets ↑ or liabilities ↓

Future earnings are usually lower as the choice reverses.

Conservative choice direction

Conservative: current earnings ↓ or assets ↓ or liabilities ↑

Future earnings are usually higher. Can create hidden reserves.

Cookie jar reserve

Overstated provision now → lower earnings now; reserve release later → higher earnings later

Used to smooth or to rescue a weak period.

Accruals signal

Accruals = Net income − Cash flow from operations

Persistently high or rising accruals relative to cash flow suggest lower earnings quality.

Revenue warning sign

Receivables growth > Sales growth

Can signal early or fictitious revenue. It is a flag, not proof.

Accruals ratio (balance sheet method)

Accruals = Change in net operating assets = NOA(end) − NOA(beginning); Accruals ratio = Accruals ÷ Average NOA

NOA = (total assets − cash and marketable securities) − (total liabilities − total debt). A high ratio suggests lower earnings quality.

Accruals ratio (cash flow method)

Accruals = NI − (CFO + CFI); Accruals ratio = Accruals ÷ Average NOA

Higher positive accruals mean more earnings come from non-cash items.

Cash flow to earnings check

CFO ÷ Net income

A ratio persistently below 1, or falling, signals earnings not backed by cash.

Days sales outstanding

Days sales outstanding = Average receivables ÷ Revenue × 365

Rising DSO with no change in credit terms suggests early or aggressive revenue recognition.

Days Sales in Receivables Index (Beneish)

DSRI = (Receivables_t ÷ Sales_t) ÷ (Receivables_t−1 ÷ Sales_t−1)

Above 1 means receivables grew faster than sales. Higher DSRI raises the M-score.

Gross Margin Index (Beneish)

GMI = Gross margin_t−1 ÷ Gross margin_t

Above 1 means margin deteriorated, which raises pressure to manipulate.

Sales Growth Index (Beneish)

SGI = Sales_t ÷ Sales_t−1

High growth increases pressure to maintain results. It is not manipulation by itself.

Audit opinion types

Unqualified (clean) | Qualified | Adverse | Disclaimer

Unqualified: fairly presented. Qualified: fairly presented except for a material but not pervasive misstatement or scope limitation. Adverse: statements are materially and pervasively misstated. Disclaimer: auditor cannot form an opinion, usually because of a pervasive scope limitation.

Level of assurance

Audit = reasonable assurance; Review = limited assurance

Neither is a guarantee against fraud or error. Reviews involve fewer procedures.

Layers of constraint

Standards + Disclosure + Regulators + Auditors + Governance

External: standards, regulators, auditors. Internal: board, audit committee, controls.

Auditor independence red flags

High non-audit fees, long tenure, personal ties, fee dependence

Each can reduce objectivity and so lower confidence in the audit.

Cash flow to earnings check

CFO ÷ Net income

A ratio persistently below 1 suggests earnings rely on accruals. Judge over several periods, not one.

Accruals ratio (balance sheet method)

(NOA end − NOA beginning) ÷ average NOA

NOA = net operating assets = (total assets − cash and marketable securities) − (total liabilities − total debt). A high or rising ratio signals lower earnings quality. There is no absolute threshold, so compare the ratio with peers or the industry, and look at its trend over time.

Accruals ratio (cash flow method)

[NI − (CFO + CFI)] ÷ average NOA

This is the cash flow accruals ratio as presented in the CFA curriculum. It uses cash flow from operations and investing, and divides by average NOA. NOA = (total assets − cash and marketable securities) − (total liabilities − total debt). Higher means earnings are less supported by cash. There is no absolute threshold, so compare the ratio with peers or the industry, and look at its trend over time.

Free cash flow to firm check

FCFF = CFO + Interest × (1 − t) − FCInv

Add back after-tax interest only when interest paid is included in CFO (US GAAP, or IFRS if the company chooses). Under IFRS, if interest paid is in CFF, CFO already excludes it and no add-back is needed. Normalise before comparing companies.

Non-GAAP reconciliation rule

Reported measure ± listed adjustments = non-GAAP measure

Regulators such as the SEC expect the non-GAAP measure to be reconciled to the nearest reported measure, with each adjustment listed and the tax effects of the adjustments disclosed. Requirements differ by jurisdiction, so treat this as a regulatory expectation, not a universal rule. As an analyst, check that the adjustments are listed and that tax effects are shown.

Quick revision

• Reporting quality is about decision-usefulness; results quality is about earnings and cash flows being sufficient and sustainable.
• High-quality reporting is compliant, with decision-useful, transparent information; the lower end of the spectrum includes biased and non-compliant reporting.
• Compliant reporting can still be biased through aggressive or conservative choices within the rules.
• High-quality earnings are sustainable, repeatable and adequate to cover the company's cost of capital.
• Aggressive choices raise current earnings, assets or cash flow; conservative choices lower them and shift income to later periods.
• Earnings management often uses estimates, timing of recognition and classification of items.
• Compare net income with operating cash flow; a persistent gap with earnings higher can signal poor quality.
• Red flags include rapid revenue growth beyond peers, unusual changes in estimates and weak internal control.
• Constraints include auditors, regulators, governance, standards and market discipline, and none is perfect.
• Non-GAAP measures must be reconciled and assessed; check what costs they exclude and whether the exclusions recur.
• Balance sheet quality asks if assets and liabilities are fairly measured and whether obligations are kept off or understated.
• Answer every question; wrong answers carry no penalty.

Common mistakes

• Treating reporting quality and earnings quality as the same thing. Fix: Reporting quality concerns the information (compliance, transparency, faithful representation). Earnings quality concerns the results (sustainable, adequate return).
• Assuming low profit means low reporting quality. Fix: A company can report weak earnings very honestly. That is high reporting quality with low earnings quality.
• Treating all unusual items as non-recurring Fix: Check whether similar charges appear in several years. If they repeat, treat them as recurring.
• Adjusting for the pre-tax amount only Fix: Multiply the item by (1 − tax rate) before adjusting net income, unless the amount is already given after tax.
• Treating conservative accounting as always good or harmless. Fix: Remember it can understate current earnings and create reserves that boost later periods. It still distorts comparability and trend.
• Calling any earnings management fraud. Fix: Earnings management often stays within the standards by using choices and estimates. Fraud breaks the rules.
• Treating a red flag as proof of fraud or manipulation. Fix: Choose answers that say the flag raises risk or calls for further analysis. Look for an innocent cause in the vignette.
• Comparing CFO with net income in a single year and drawing a firm conclusion. Fix: Look at the trend over several years. A persistent or widening gap matters more than one gap.
• Treating a clean audit opinion as proof that the statements are accurate. Fix: Remember an audit gives reasonable assurance on fair presentation in all material respects, not absolute assurance or a guarantee against fraud.
• Assuming compliance with standards means high quality reporting. Fix: Standards allow choices and estimates. Compliant reports can still be low quality if the choices are aggressive.

Exam tips

• Expect a vignette that describes a company in words and asks you to place it on the spectrum. Match each fact to either reporting quality or earnings quality before choosing.
• Watch for the pair of answers: the strongest wrong options mix up the two concepts, such as calling one-off profit a reporting problem.
• Remember the dependency: if reporting is unreliable, earnings quality is hard to assess. This often decides a close question.
• Place the company at the level that best fits the facts. Do not assign fraud or non-compliance unless the vignette shows it, such as fictitious transactions or deliberate falsification.
• There is no penalty for wrong answers, so answer every question, but read the vignette wording on compliance carefully first.
• Always ask whether an item repeats. The vignette often gives prior-year history to test this.
• Apply the tax rate to each adjustment unless the figure is already after tax.
• Remember that quality has two parts: sustainability and adequate return. Check both before choosing an answer.
