SOCPA Auditing cheat sheet

Audit risk = Inherent risk × Control risk × Detection risk; detection risk is the only component the auditor controls through the nature, timing, and extent of procedures.

Materiality: overall materiality is often set at 0.5%–1% of total revenue, 1%–2% of total assets, or 5%–10% of profit before tax; performance materiality is typically 50%–75% of overall materiality.

Sufficiency relates to the quantity of audit evidence; appropriateness relates to its relevance and reliability. External evidence is more reliable than internal evidence; documentary evidence more reliable than oral.

The auditor expresses an unmodified opinion when the financial statements are prepared, in all material respects, in accordance with the applicable financial reporting framework.

A modified opinion is either qualified (material but not pervasive misstatement), adverse (material and pervasive misstatement), or a disclaimer (inability to obtain sufficient appropriate evidence that is material and pervasive).

ISA 315 requires the auditor to identify and assess risks of material misstatement at the financial statement level and at the assertion level (classes of transactions, account balances, disclosures).

ISA 700 requires the auditor's report to include the opinion, basis for opinion, going concern conclusion (when applicable), key audit matters (for listed entities), and responsibilities of management and the auditor.

Independence: an auditor must be independent in mind (state of mind) and in appearance (avoid facts and circumstances that a reasonable third party would perceive as compromising independence).

Sampling risk is the risk that the auditor's conclusion based on a sample differs from the conclusion if the entire population were tested; non-sampling risk arises from human error or inappropriate procedures.

The accounting equation: Assets = Liabilities + Equity. Every transaction preserves this equality (double-entry bookkeeping).

Revenue recognition (IFRS 15): identify the contract, identify performance obligations, determine the transaction price, allocate the price to obligations, and recognize revenue when (or as) each obligation is satisfied.

Depreciation methods: straight-line = (cost − residual value) / useful life; reducing balance = carrying amount × rate; units of production = (cost − residual) × units produced / total expected units.

Inventory valuation (IAS 2): lower of cost and net realizable value (NRV). Cost includes purchase price, conversion costs, and other costs to bring inventory to its present location and condition.

Impairment (IAS 36): an asset is impaired when its carrying amount exceeds its recoverable amount (higher of fair value less costs of disposal and value in use).

Leases (IFRS 16): a lessee recognizes a right-of-use asset and a lease liability measured at the present value of lease payments, discounted at the interest rate implicit in the lease or the lessee's incremental borrowing rate.

Provisions (IAS 37) are recognized when there is a present obligation from a past event, a probable outflow of resources, and a reliable estimate; contingent liabilities are disclosed, not recognized.

Consolidation (IFRS 10): control exists when the parent has power over the investee, exposure to variable returns, and the ability to use its power to affect those returns.

Contribution margin = Sales − Variable costs. Contribution margin ratio = Contribution margin / Sales. Break-even point in units = Fixed costs / Contribution per unit.

Break-even point in sales value = Fixed costs / Contribution margin ratio. Margin of safety = (Actual sales − Break-even sales) / Actual sales.

Target profit volume = (Fixed costs + Target profit) / Contribution per unit.

High-low method: Variable cost per unit = (Cost at high activity − Cost at low activity) / (High activity − Low activity); Fixed cost = Total cost − (Variable cost per unit × Activity level).

Overhead absorption rate = Budgeted overhead / Budgeted activity level (e.g., direct labor hours, machine hours). Under/over-absorption = Actual overhead − Absorbed overhead.

Standard costing variances: Material price variance = (Standard price − Actual price) × Actual quantity; Material usage variance = (Standard quantity − Actual quantity) × Standard price.

Labor rate variance = (Standard rate − Actual rate) × Actual hours; Labor efficiency variance = (Standard hours − Actual hours) × Standard rate.

Relevant costs for decision-making are future, incremental cash flows that differ between alternatives; sunk costs and allocated fixed costs are irrelevant.

Process costing: equivalent units = units completed + (ending work-in-process × percentage completion). Cost per equivalent unit = Total costs / Equivalent units.

Zakat (Saudi Arabia): 2.5% on the Zakat base for Saudi/GCC-owned entities; the Zakat base generally equals adjusted profit plus certain equity items minus certain deductions (e.g., fixed assets, investments).

Corporate income tax (Saudi Arabia): 20% on the tax-adjusted net income of foreign-owned entities (non-Saudi/GCC shareholders).

Withholding tax on cross-border payments: 5% on dividends and interest, 5%–15% on royalties (15% for royalties), 5% on technical service fees, 5% on rent, and 5% on other services, subject to treaty relief.

Value Added Tax (Saudi Arabia): standard rate 15%; registration is mandatory when annual taxable turnover exceeds SAR 375,000 and optional when it exceeds SAR 187,500.

VAT return filing: monthly for businesses with annual taxable turnover above SAR 40 million; quarterly for others; returns are due within 30 days after the end of the tax period.

Real Estate Transaction Tax (RETT): 5% on the value of real estate disposals, generally payable by the seller, with limited exemptions (e.g., certain inheritances and gifts).

Tax depreciation: buildings 5%, plants and machinery 25%, equipment and vehicles 25%, furniture and fixtures 10%, and intangible assets 10% (straight-line unless otherwise specified).

Advance tax payments: monthly installments based on the prior year's tax liability, with a final true-up on filing the annual return within 120 days of the fiscal year-end.

Saudi Companies Law (2015): a joint stock company (JSC) requires a minimum of two shareholders and capital of at least SAR 500,000; a limited liability company (LLC) requires at least one shareholder and has no statutory minimum capital.

A JSC must have a board of directors of at least three members (maximum 11), and the board must appoint a qualified auditor; the auditor's report is presented to the general assembly.

The external auditor of a Saudi company must be a Saudi Organization for Chartered and Professional Accountants (SOCPA) licensed accountant or firm; the auditor is appointed by the general assembly for a renewable term.

Fundamental ethical principles (IESBA/SOCPA Code): integrity, objectivity, professional competence and due care, confidentiality, and professional behavior.

The conceptual framework requires identifying threats (self-interest, self-review, advocacy, familiarity, intimidation) and applying safeguards; if safeguards cannot reduce threats to an acceptable level, the engagement must be declined or terminated.

Independence is required for audit and review engagements; for non-assurance services, the auditor must evaluate whether providing the service creates a self-review or advocacy threat.

Confidentiality: information acquired in the course of professional work may not be disclosed without proper authority unless there is a legal or professional right or duty to disclose.

Professional fees: fees should reflect the time, skill, and responsibility involved; contingent fees based on the outcome of an audit are prohibited because they create a self-interest threat.
