7.2 Accounting Policies – Reliability

What are accounting policies?

Think of them as the recipe a company follows when it prepares its financial statements. They are the specific principles, rules, and practices that decide how numbers are recorded, measured, and presented.

Why Reliability Matters

Reliability means the financial information is faithful, accurate, and useful for decision‑makers. If policies are clear and consistently applied, the numbers you read are trustworthy.

Faithful Representation: All material facts are included and not distorted.
Accuracy: Numbers are measured correctly (e.g., using the right cost basis).
Completeness: No important information is omitted.
Consistency: The same policy is used from year to year unless a change is justified.

Common Accounting Policies & Examples

Policy Area	Typical Policy	Why It Matters
Revenue Recognition	Revenue is recognised when it is earned and measurable.	Ensures sales are shown in the correct period, avoiding over‑ or under‑statement.
Inventory Valuation	Use FIFO or LIFO consistently.	Affects cost of goods sold and profit margins.
Depreciation Method	Straight‑line or declining balance.	Shows how asset value decreases over time.

Analogy: The Game of Accounting

Imagine playing a board game where each player must follow the same rules. If one player secretly changes the rules, the game becomes unfair. Similarly, if a company changes its accounting policies without clear reason, the financial statements become unreliable.

Exam Tips 📚

When asked to explain a policy, start with the definition, then give a simple example.
Use the analogy of a recipe or game rules to show why consistency matters.
Remember the four reliability criteria – faithfulness, accuracy, completeness, consistency.
Show LaTeX for key equations, e.g. $Revenue = \text{Cash received} + \text{Credit sales}$ .
When comparing two policies, use a table to highlight differences clearly.
