Accounting Principles and Ethics (SACE Stage 2 Accounting)
“Explain the key accounting principles and ethical responsibilities that underpin reliable financial reporting”
Accounting principles (such as accrual, going concern, the entity principle, prudence, consistency and the period assumption) make financial reports reliable and comparable. Ethical reporting adds integrity, objectivity and honesty, so that information is not manipulated to mislead users.

What this dot point is asking
You need to explain the main accounting principles and concepts, show how they shape the preparation of statements, and describe the ethical responsibilities of those who prepare accounting information.
Why principles exist
Financial statements are only useful if users can trust and compare them. Principles are the agreed rules that make information relevant, reliable, comparable and understandable. They tell preparers what to recognise, when, and at what value.
Key accounting principles
- Accounting entity: the business is separate from its owner; only business transactions are recorded.
- Going concern: statements assume the business will continue operating for the foreseeable future, justifying recording assets at cost rather than fire-sale value.
- Accrual basis: revenue is recognised when earned and expenses when incurred, regardless of cash timing.
- Period (time interval): activity is divided into regular periods so performance can be reported.
- Monetary unit: only items measurable in dollars are recorded.
- Historical cost: assets are initially recorded at their original cost.
- Prudence (conservatism): do not overstate assets or income, nor understate liabilities or expenses.
- Consistency: the same methods are used period to period so results are comparable.
How principles shape statements
These principles are not abstract; they decide the numbers. Accrual means a year-end electricity bill not yet paid is still recorded as an expense and an accrued liability. Going concern justifies spreading an asset's cost over its useful life through depreciation rather than writing it off at once. Prudence supports recording an allowance for doubtful debts when collection is uncertain. The entity principle is why an owner's personal car, paid from personal funds, never enters the business records.
An item is material if omitting or misstating it could influence a user's decision. Immaterial items can be treated in the simplest practical way (for example, expensing a cheap stapler rather than depreciating it).
Ethics in accounting
Beyond the technical rules, those who prepare and report financial information carry ethical responsibilities. The professional values commonly expected are:
- Integrity: being honest and straightforward in all dealings.
- Objectivity: not letting bias, conflict of interest or pressure override judgement.
- Professional competence and due care: keeping skills current and working carefully.
- Confidentiality: not misusing information acquired through work.
- Professional behaviour: complying with laws and not discrediting the profession.
Ethical failures, such as overstating revenue, hiding liabilities or manipulating profit to secure a loan or bonus, mislead users and can cause real harm to investors, lenders, employees and the public.
A business near year-end
A business has performed of services in late June but will not invoice or be paid until July. The owner suggests leaving it out of this year's accounts to keep the figures simple.
Principle: under the accrual basis, revenue is recognised when earned, not when cash is received. The service was performed in June, so of revenue and a corresponding accrued receivable belong in this year's statements.
Ethics: omitting earned revenue would understate profit and mislead users who rely on the statements. Acting with integrity and objectivity, the preparer should record the revenue correctly despite the owner's preference for convenience. Applying the principle and the ethic gives the same answer: report it now.
Confusing the accounting entity principle with a legal one. For a sole trader, the owner and business are the same legal person, but accounting still treats them as separate entities. Mixing the owner's private spending into the business records (or vice versa) breaches the entity principle and distorts both profit and owner's equity.
Exam-style questions
Questions in the style of SACE Board exam questions on this dot point, each with a worked answer. They are written by ExamExplained unless tagged "Past paper"; the year shows the paper a question is modelled on.
2023 SACE Stage 2-style2 marksExplain how the monetary unit convention is applied to financial reports, and why it is important in the preparation of these reports.Show worked answer →
The monetary unit convention says that only items able to be measured reliably in money (a common unit, the Australian dollar) are recorded in the accounting records, and that the dollar is treated as a stable measure of value.
Application: every transaction, asset and liability is recorded as a dollar amount, so a cash budget, income statement and balance sheet are all expressed in dollars.
Importance: using one common money measure lets different items be added, compared and reported together, making the statements consistent, comparable and understandable. Items that cannot be measured in money, such as staff morale or the owner's skill, are excluded even if valuable.
Markers reward a definition (recording only what can be measured in money, in a common currency) plus a reason linked to comparability and consistency of the reports.
2024 SACE Stage 2-style2 marksExplain how investing activities listed in the statement of cash flows relate to the going concern concept.Show worked answer →
The going concern concept assumes the business will continue operating for the foreseeable future and is not about to be wound up.
Investing activities (such as buying buildings, furniture or equipment) are cash outflows on long-term assets the business expects to use over many years to keep generating revenue. Spending on these non-current assets only makes sense if the business expects to keep operating, so it reflects the going concern assumption in action.
It also justifies why such assets are recorded at cost and depreciated over their useful lives rather than written off immediately or valued at fire-sale prices: the business expects to use them, not sell them up.
Markers reward defining going concern and linking the purchase or sale of long-term assets to the expectation that the business will continue operating.
2024 SACE Stage 2-style3 marksFor the balance sheet extract of Illuminated Lighting: (i) outline why accumulated depreciation is not an example of the prudence assumption being applied; (ii) state where the prudence assumption is being applied; (iii) outline how the concept of materiality is applied.Show worked answer →
(i) Accumulated depreciation is the systematic allocation of an asset's cost over its useful life (the matching idea), not a cautious estimate of an uncertain loss. It is calculated by a set method, so it reflects cost allocation rather than prudence.
(ii) Prudence is applied through the allowance for doubtful debts, where an estimated future loss is recognised now so assets (net debtors) and profit are not overstated. Recording inventory at the lower of cost and net realisable value is another valid example.
(iii) Materiality is applied when items are reported in a way that reflects their significance to users, for example grouping small or insignificant amounts together, or rounding to whole dollars, so the statements are not cluttered with detail that would not change a decision.
Markers reward distinguishing cost allocation (depreciation) from caution (prudence), correctly naming the allowance for doubtful debts as prudence, and a sound materiality example.
