Accounting concepts and principles

The accounting concepts are the fundamental assumptions and rules that govern how transactions are recorded and financial statements prepared, so that the figures mean the same thing to everyone who reads them. This chapter explains the recording concepts, going concern and accruals, and prudence, consistency and materiality, shows how they determine the correct accounting treatment, and evaluates the tensions between them.

Accounting concepts and principles

The recording concepts: entity, money measurement, historical cost and dual aspect#

FoundationAQA 7127 3.5

The accounting concepts

Fig. 1The concepts group into those that govern recording (entity, money measurement, historical cost, dual aspect) and those that govern the preparation of statements (going concern, accruals, prudence, consistency, materiality).

Four concepts govern what gets recorded and how. The business entity concept treats the business as separate from its owner: only the transactions of the business are recorded in its books, and the owner's private assets and spending are kept out. This is why money the owner puts in is 'capital' (owed by the business to the owner) and money taken out is 'drawings' - the business and the owner are accounted for as distinct, even where, as with a sole trader, they are legally the same person. Without this concept the accounts would mix business and personal affairs and reveal nothing about the business itself.

The money measurement concept records only those things that can be reliably expressed in money terms. This gives accounts a common unit and makes them addable and comparable, but it also means that important non-financial factors - the skill and morale of the workforce, the strength of a brand built up over years, the quality of management, customer loyalty - do not appear in the statement of financial position unless they have been bought and paid for. This is a significant limitation to remember in interpretation: two firms with identical accounts can be worth very different amounts because of things money measurement leaves out.

The historical cost concept records assets at what was actually paid for them, not at their current market value. Its great strength is objectivity and verifiability - the cost is a fact evidenced by a document, not an opinion - which makes the figures reliable and hard to manipulate. Its weakness is relevance: in a period of rising prices, assets bought long ago are shown at amounts far below their current worth, so the statement of financial position can understate the real value of the business and profit can be overstated (because depreciation is based on old, low costs). Historical cost trades relevance for reliability, and the debate between the two runs through the interpretation chapter.

The dual aspect concept is the one already met as the foundation of double entry: every transaction has two equal and opposite effects, so that the accounting equation always balances. It is the concept that makes the recording system self-checking. Taken together, these four recording concepts fix the boundaries of the accounts (entity), the unit of measurement (money measurement), the basis of valuation (historical cost) and the method of recording (dual aspect) - the scaffolding on which everything else is built. They are so basic that they are easy to overlook, but many exam scenarios turn on one of them, such as whether a particular item should be recorded at all.

Worked example

Applying the business entity concept

An owner takes £500 of goods from the business for personal use and buys a £300 personal item with the business debit card. Explain the correct treatment using the business entity concept.

Identify the concept
The business entity concept requires the business's affairs to be kept separate from the owner's; personal benefit taken from the business is drawings, not a business expense.
Treat the goods taken
The £500 of goods is drawings: debit drawings £500 and credit purchases £500 (the goods leave the business for the owner's use, at cost).
Treat the personal purchase
The £300 personal item is not a business expense: debit drawings £300 and credit bank £300 - it reduces the owner's capital, not the business's profit.

Result: Both items are drawings under the business entity concept: £500 of goods (Dr drawings, Cr purchases) and £300 spent personally (Dr drawings, Cr bank) - neither is a business expense, so profit is unaffected.

Typical mistakes

Recording an owner's private expense in the business accounts, breaching the business entity concept.
Assuming assets appear at current value - historical cost records them at what was paid.

Active revision

A sole trader pays her personal council tax from the business bank account and records it as a business expense. Name the concept breached and state the correct treatment.

Going concern and the accruals concept#

StandardAQA 7127 3.5

Accruals and prepayments

Fig. 2The accruals concept in action: accrued expenses are added and become liabilities; prepaid expenses are deducted and become assets, matching each cost to its period.

The going concern concept assumes that the business will continue to operate for the foreseeable future, with no intention or need to close down or sell off its assets. This assumption justifies much of normal accounting practice: assets are shown at cost less depreciation (their value in use) rather than at what they would fetch in a forced sale, and prepayments and other assets are carried forward on the basis that the business will still be there to benefit from them next year. If a business were not a going concern - if closure were imminent - its assets would instead be valued at their (usually much lower) break-up or net realisable value, and the whole picture would change. The going concern assumption therefore underpins the valuations in a normal set of accounts.

The accruals concept (also called the matching concept) requires that revenue and costs are recognised in the period to which they relate - when they are earned or incurred - rather than when the cash is received or paid. Revenue is recognised when it is earned (goods delivered or services performed), and the costs incurred in earning that revenue are matched against it in the same period. This is what makes profit a meaningful measure of performance: it matches the effort (costs) with the achievement (revenue) of a period, so profit reflects what the business actually did rather than the accident of when money happened to move. The accruals concept is the reason profit differs from cash flow.

In practice the accruals concept is applied through the year-end adjustments for accruals and prepayments. An accrued expense is a cost incurred but not yet paid (for example electricity used but not yet invoiced): it is added to the expense for the year and shown as a current liability. A prepaid expense is a cost paid in advance of the period it covers (for example rent paid for next quarter): it is deducted from the expense for the year and shown as a current asset. The same logic applies to income received in advance (a liability) or accrued income owed to the business (an asset). These adjustments move each cost and revenue into the correct period, which is exactly what the accruals concept demands.

A short calculation makes the mechanism concrete. Suppose rent of £12,000 was paid during the year, but £2,000 of that relates to the following year (it was paid in advance). The accruals concept says the expense for this year is only the £10,000 that relates to this year, so the income statement is charged £10,000 and the £2,000 prepayment is carried forward as a current asset. If instead £1,500 of wages had been incurred but not yet paid at the year end, that £1,500 is added to the wages expense and shown as an accrual (a current liability). Applying the accruals concept correctly is essential to measuring profit properly, and it is tested in almost every financial-statements question.

\text{Expense for the year} = \text{Amount paid} + \text{Closing accrual} - \text{Opening accrual} - \text{Closing prepayment} + \text{Opening prepayment}

Adjusting an expense to the accruals basis

Converts the cash paid into the cost incurred in the period, matching the expense to the year it relates to.

Worked example

Applying accruals and prepayments

During the year a business paid rent of £12,000, of which £2,000 was for the following year. It also used £400 of electricity in the final month that has not yet been invoiced or paid. Calculate the rent and electricity charged to the income statement and the SOFP items.

Adjust the rent (prepayment)
Of the £12,000 paid, £2,000 relates to next year, so the expense for this year is £12,000 - £2,000 = £10,000. The £2,000 is a prepayment - a current asset.
Adjust the electricity (accrual)
£400 of electricity was incurred but not paid, so it is added to the expense: the electricity charge includes the £400, which is an accrual - a current liability.
State the statements
Income statement: rent £10,000 and the electricity accrual of £400 included in expenses. Statement of financial position: a £2,000 prepayment (current asset) and a £400 accrual (current liability).

Result: Rent charged is £10,000 (with a £2,000 prepayment as a current asset) and the £400 unpaid electricity is accrued (added to the expense and shown as a current liability) - each cost matched to the period it relates to.

Typical mistakes

Charging the cash paid to the income statement instead of the amount that relates to the period.
Putting an accrual as an asset or a prepayment as a liability - accruals are liabilities, prepayments are assets.

Active revision

Rent of £12,000 was paid in the year, of which £2,000 relates to next year. Insurance of £3,000 was paid, but £400 for the final month is still owing. Calculate the rent and insurance expenses for the income statement and the amounts shown in the statement of financial position.

Prudence, consistency and materiality#

StandardAQA 7127 3.5

Prudence, consistency and materiality

Fig. 3Each concept, its meaning and a typical application - prudence in inventory valuation, consistency in depreciation method, materiality in expensing small items.

The prudence concept requires caution in the face of uncertainty: profits and assets should not be overstated, and losses and liabilities should not be understated. In practice this means recognising a loss as soon as it is foreseen but not recognising a profit until it is reasonably certain (realised). Prudence is why inventory is valued at the lower of cost and net realisable value (so a fall in value is recognised at once but a rise is not), why an allowance is made for doubtful debts, and why anticipated liabilities are provided for. Its purpose is to protect users - especially creditors - from an over-optimistic picture that might lead them to lend or invest unwisely. Prudence errs, deliberately, on the side of caution.

The consistency concept requires that once an accounting policy or method has been chosen - a depreciation method, an inventory valuation approach - it is applied consistently from one period to the next, and changed only for good reason and with disclosure. The purpose is comparability: if a business switched depreciation methods each year, its profits could not meaningfully be compared over time, and a manager could flatter the figures by choosing whichever method suited each year. Consistency does not forbid change forever - a better policy may be adopted - but it demands that change be justified and its effect disclosed, so that users are not misled by an apparent trend that is really just a change of method.

The materiality concept recognises that accounting should not be obsessed with trivial amounts: an item is material if its omission or misstatement could influence the decisions of users, and only material items need be treated strictly. This is why a business can charge a cheap stapler straight to expenses rather than capitalising and depreciating it as a non-current asset - the amount is too small to affect any decision, so the strict treatment is not worth the effort. Materiality is a matter of judgement and of relative size (£1,000 is material to a corner shop but immaterial to a multinational), and it allows sensible, cost-effective accounting without breaching the spirit of the other concepts.

These three concepts are best understood as serving the usefulness of the accounts, and they interact with the recording concepts and with each other. Prudence supports faithful representation by preventing overstatement; consistency supports comparability; materiality supports understandability and keeps the cost of information proportionate. But they can also pull against one another and against the qualitative characteristics - most notably, an over-zealous application of prudence can deliberately understate assets and profits, which conflicts with the requirement that information be neutral (neither optimistic nor pessimistic). Recognising these interactions is what separates a descriptive answer from an evaluative one.

Worked example

Prudence in inventory valuation

A line of inventory cost £8,000. Because it is out of fashion, it can now be sold for only £6,000, and £500 of selling costs will be incurred to sell it. At what value should it appear, and why?

Calculate net realisable value
Net realisable value = expected selling price - costs to sell = £6,000 - £500 = £5,500.
Apply the lower of cost and NRV
Inventory is valued at the lower of cost (£8,000) and net realisable value (£5,500), so it is written down to £5,500.
State the concept
Prudence requires the foreseeable loss of £2,500 (£8,000 - £5,500) to be recognised now rather than carried forward, so the inventory is shown at £5,500 and the loss reduces this year's profit.

Result: The inventory is valued at its net realisable value of £5,500 (below cost of £8,000), recognising the £2,500 loss immediately - the prudence concept applied through the lower of cost and NRV rule.

Typical mistakes

Applying prudence to understate profit deliberately, which breaches neutrality - prudence means caution under uncertainty, not pessimism.
Treating every small item strictly, ignoring materiality and wasting effort.

Active revision

Inventory that cost £8,000 can now be sold for only £6,000 after £500 of selling costs. State the value at which it should appear and the concept that requires it.

Applying and evaluating the concepts#

AdvancedAQA 7127 3.5

The tension between prudence and neutrality

Fig. 4Prudence guards against overstatement, but taken too far it becomes bias; neutrality and faithful representation keep it in check.

In an examination the concepts are rarely tested by asking for a definition; they are tested by asking you to decide the correct treatment of a transaction and to justify it by naming the concept. Should development spending be capitalised or expensed? Should a possible legal claim be provided for? Should a small tool be capitalised? Should inventory be written down? Each of these turns on one or more concepts - accruals, prudence, materiality, going concern - and the mark is earned by identifying the relevant concept and applying it correctly, not by reciting a list. Training yourself to ask 'which concept governs this?' is the practical skill this chapter builds.

The concepts also frequently conflict, and handling the conflict is where the top marks lie. The clearest tension is between prudence and neutrality: prudence tells us to be cautious and not overstate, but the qualitative characteristic of faithful representation demands neutrality - information that is neither optimistic nor pessimistic. Pushed too far, prudence becomes bias: creating excessive provisions in a good year (understating profit) to release them in a bad year (overstating profit) is 'profit smoothing', which is prudent in appearance but misleading in substance. Modern frameworks resolve this by defining prudence as the exercise of caution under uncertainty, not as deliberate understatement - a subtle but important distinction.

Other tensions matter too. Consistency versus improvement: consistency aids comparability, but a business should be free to adopt a better accounting policy - the resolution is to allow the change but disclose it and its effect. Relevance versus reliability, met under historical cost: current values are more relevant but less reliable than historical cost, and the framework's compromise is to keep historical cost as the default while requiring some assets to be revalued or tested for impairment. Materiality versus completeness: strict completeness would record every trivial item, but materiality sensibly relaxes this where amounts are too small to affect decisions. In each case the resolution is a reasoned trade-off, not the victory of one concept over another.

For evaluation, the message is that the concepts are not a rigid rulebook but a coherent framework of principles whose application requires judgement. They exist to make accounts useful - reliable, comparable, relevant and understandable - to the many users who depend on them, and they are ultimately justified by that purpose. When concepts conflict, the accountant weighs them in the light of what will give users a true and fair view, which is why the same framework that supplies the concepts also supplies the qualitative characteristics that adjudicate between them. This principled, judgement-based character is what makes accounting a profession rather than a clerical routine - and it leads directly into the ethics of the final chapter, where the pressure to bend the concepts is confronted head on.

Worked example

Evaluating profit smoothing

In a very profitable year a company sets aside a large provision for possible future costs that are not yet probable, planning to reverse it in a lean year. Evaluate this using the accounting concepts.

Identify the concept invoked
The company claims to be applying prudence - being cautious by providing for possible future costs and not overstating this year's profit.
Test it against neutrality
The costs are not yet probable, so the provision is not genuine caution under uncertainty but a deliberate understatement of profit; releasing it later will overstate a future profit. This breaches neutrality and faithful representation - it is profit smoothing.
Reach a judgement
The practice is not acceptable: prudence justifies providing for probable losses, not for creating hidden reserves to manipulate the profit trend. It misleads users about performance and would be regarded as creative accounting, an ethical failure.

Result: The large provision is not prudence but bias: it understates profit now and overstates it later, breaching neutrality - unacceptable profit smoothing rather than legitimate caution.

Typical mistakes

Listing concepts without applying them to the specific transaction in the question.
Treating prudence and neutrality as the same thing, missing the tension that deliberate understatement creates.

Active revision

A company creates a large 'general provision' in a highly profitable year, intending to release it in a future poor year. Explain which concepts are engaged and evaluate whether this is acceptable.
