Regulatory Framework and Governance

  • Standard-setting hierarchy: legislation outranks regulations, which outrank accounting standards, which outrank interpretive guidance; a conflict is resolved in that order.

  • A principles-based framework states objectives and qualitative characteristics; a rules-based framework supplies bright-line thresholds and detailed scope exceptions.

  • Governance separation of duties: the board sets strategy and oversight, management executes, the audit committee oversees external reporting and the external auditor.

  • Independence safeguards for the audit committee include no material consulting fees to the auditor, at least one financial expert, and a charter defining authority.

  • Internal control framework has five components: control environment, risk assessment, control activities, information and communication, and monitoring activities.

  • A control deficiency is a design or operating shortfall; a significant deficiency is less severe than a material weakness but important enough to merit governance attention.

  • Ethical decision tests: legality, stakeholder impact, disclosure test (would the decision survive publication), and consistency (would it apply to anyone in the same position).

  • Regulatory filing deadlines and thresholds are jurisdiction-specific; confirm the applicable statute rather than assuming a single global rule.

Financial Accounting and Reporting

  • Accounting equation: Assets = Liabilities + Equity; every transaction preserves this equality.

  • Accrual basis records revenue when the performance obligation is satisfied and expenses when the obligation is incurred, regardless of cash timing.

  • Revenue recognition steps: identify the contract, identify performance obligations, determine transaction price, allocate price to obligations, recognize on satisfaction.

  • Depreciation: straight-line = (cost − residual) / useful life; double-declining = 2 / life × carrying amount; units-of-production = (cost − residual) × units used / total units.

  • Inventory cost flow: FIFO leaves the newest costs in ending inventory; weighted average smooths price changes; LIFO is not permitted under IFRS.

  • Lower of cost and net realizable value writes inventory down; the write-down is not reversed under US GAAP but may be reversed under IFRS when conditions improve.

  • Impairment test compares carrying amount with recoverable amount (higher of fair value less costs to sell and value in use); the excess is the impairment loss.

  • Statement of cash flows: operating (accrual earnings adjusted for non-cash items and working capital), investing (long-term assets), financing (debt and equity).

Management Accounting and Cost Analysis

  • Contribution margin = sales − variable costs; contribution margin ratio = contribution margin / sales.

  • Break-even units = fixed costs / unit contribution margin; break-even sales = fixed costs / contribution margin ratio.

  • Target profit volume = (fixed costs + target profit) / unit contribution margin.

  • Margin of safety = actual (or budgeted) sales − break-even sales; expressed as a percentage, divide by actual sales.

  • High-low method: variable cost per unit = (highest cost − lowest cost) / (highest activity − lowest activity); fixed cost = total cost at a point − variable rate × activity.

  • Overhead applied = predetermined rate × actual activity; underapplied when actual overhead exceeds applied, overapplied when applied exceeds actual.

  • Relevant costs are future and differ between alternatives; sunk costs and allocated fixed costs that do not change are irrelevant to the decision.

  • A favorable variance is not automatically good: a materials price variance may reflect cheaper, lower-quality inputs that raise usage and rework costs.

Auditing and Assurance

  • Audit risk model: audit risk = inherent risk × control risk × detection risk; detection risk is the auditor-controlled component, so higher inherent or control risk requires more substantive testing.

  • Assertions tested: occurrence, completeness, accuracy, cut-off, classification (transactions); existence, rights and obligations, completeness, valuation (balances).

  • Evidence reliability ranking: auditor's direct observation and external confirmations outrank internally generated documents, which outrank oral representations.

  • Materiality is set as a percentage of a benchmark (profit before tax, revenue, total assets, or equity); performance materiality is lower to cover undetected misstatements.

  • Sampling risk is the risk that the sample conclusion differs from the population; non-sampling risk is human error, wrong procedures, or misinterpretation.

  • An unmodified opinion requires the financial statements to be free of material misstatement; a qualified opinion is issued for material but not pervasive departures.

  • Going concern: if substantial doubt exists but disclosure is adequate, an unmodified opinion with an emphasis-of-matter or material-uncertainty paragraph may be appropriate.

  • Independence prohibits an auditor from assuming management responsibilities, preparing source records, or having a direct material financial interest in the client.

Taxation

  • Taxable income = accounting income adjusted for permanent differences (never taxable or deductible) and temporary differences (timing reversals).

  • A permanent difference changes the effective tax rate; a temporary difference creates a deferred tax asset or liability at the enacted future rate.

  • Deferred tax asset recognition requires probable future taxable profit sufficient to use the deductible difference or loss carryforward.

  • Valuation allowance reduces a deferred tax asset to the amount more likely than not to be realized.

  • Progressive rate structures apply marginal rates to brackets; the average rate equals total tax divided by total taxable income and is always below the marginal rate.

  • Tax base of an asset is the amount deductible for tax purposes in future periods; if it equals carrying amount, no temporary difference exists.

  • A tax position is recognized only if it is more likely than not to be sustained on technical merit; the benefit is measured at the largest amount more than 50 percent likely to be realized.

  • Jurisdictional nexus, filing thresholds, and rates vary; never apply a single assumed rate without confirming the governing tax statute.

Business Law and Ethics

  • Contract formation requires offer, acceptance, consideration, capacity, and legality; a counteroffer terminates the original offer.

  • An agent binds a principal when acting with actual authority (express or implied) or apparent authority created by the principal's manifestations to a third party.

  • Fiduciary duties of agents and directors: duty of care (informed, reasonable process) and duty of loyalty (no self-dealing, no undisclosed conflict).

  • Business judgment rule protects directors who act in good faith, on an informed basis, and without personal interest, even if the outcome is poor.

  • Statute of frauds categories commonly include land sales, contracts that cannot be performed within one year, and suretyship promises.

  • Negligence elements: duty, breach, causation (actual and proximate), and damages; comparative or contributory fault may reduce or bar recovery.

  • Ethical frameworks: utilitarianism weighs aggregate consequences; deontology applies duties and rules regardless of outcome; virtue ethics asks what a person of integrity would do.

  • Whistleblower protections generally require a reasonable good-faith belief of a legal violation and reporting through a defined internal or regulatory channel.

Information Technology and Controls

  • IT general controls cover access management, change management, program development, and computer operations; they underpin reliance on automated application controls.

  • Application controls are input (validation, edit checks), processing (run-to-run totals, reasonableness tests), and output (distribution, reconciliation) controls.

  • Segregation of duties in IT: developers do not have production access, and the person who authorizes a change does not implement it.

  • A test of one automated control may support the full period only if general controls over program changes and access are effective.

  • Batch total reconciliation compares record counts, financial totals, and hash totals before and after processing to detect lost or altered records.

  • Encryption protects confidentiality in transit and at rest; hashing provides integrity evidence but is not reversible and is not encryption.

  • Business continuity differs from disaster recovery: continuity keeps critical operations running, recovery restores systems after an outage.

  • A SOC report: SOC 1 covers controls relevant to financial reporting; SOC 2 covers security, availability, processing integrity, confidentiality, and privacy.
