5 Finance & Accounting (AS 5)

5.1 Working‑Capital Management

Working capital = Current assets – Current liabilities. It measures short‑term financial health.

5.2 Sources of Finance (Short‑ & Long‑Term)

Source	Typical Use	Advantages	Disadvantages
Bank overdraft	Cover cash‑flow gaps	Flexible, quick access	High interest, may be withdrawn.

Term loan	Plant, equipment	Fixed repayments	Collateral required.
Equity (share issue)	Expansion, R&D	No repayment obligation	Dilutes ownership.

5.3 Costing Methods

• Absorption costing: All production costs (fixed & variable) allocated to units.
• Marginal (variable) costing: Only variable costs allocated; fixed costs treated as period expenses.

5.4 Break‑Even Analysis

Break‑Even Point (units) = Fixed Costs ÷ (Selling price per unit – Variable cost per unit).

5.5 Budgeting & Variance Analysis

• Prepare flexible budgets based on actual activity levels.
• Calculate variances: Actual – Budgeted. Investigate favourable/unfavourable causes.

5.6 Liquidity – The Focus of This Section

5.6.1 What is Liquidity?

• Definition: The ability of a business to convert assets into cash quickly and without a material loss of value so that short‑term liabilities can be met when they fall due.
• Directly linked to working capital – a positive working‑capital balance is a basic indicator of liquidity.
• Why it matters:
  • Ensures timely payment of suppliers, staff and interest.
  • Reduces risk of insolvency and the need for emergency financing.
  • Builds confidence among creditors, investors and other stakeholders.

5.6.2 The Three Principal Liquidity Ratios

Ratio	Formula	What it Measures	Typical “Acceptable” Range*
Current Ratio	\(\displaystyle \frac{\text{Current Assets}}{\text{Current Liabilities}}\)	All current assets available to meet current liabilities.	Manufacturing: 1.5 – 2.5 Service: 1.2 – 2.0
Quick Ratio (Acid‑test)	\(\displaystyle \frac{\text{Current Assets} - \text{Inventory}}{\text{Current Liabilities}}\)	Liquidity without relying on inventory sales.	Manufacturing: 1.0 – 1.5 Service: 0.8 – 1.3
Cash Ratio	\(\displaystyle \frac{\text{Cash} + \text{Cash Equivalents}}{\text{Current Liabilities}}\)	Ability to pay current liabilities immediately using cash only.	Generally 0.2 – 0.5 (higher in capital‑intensive sectors)

*Ranges are indicative; always compare with the firm’s own industry sector and historical performance.

5.6.3 Step‑by‑Step Worksheet – Calculating the Ratios

Component	Amount (£’000)	Included in Current Ratio?	Included in Quick Ratio?	Included in Cash Ratio?
Cash and cash equivalents		Yes	Yes	Yes
Trade receivables		Yes	Yes	No
Inventory		Yes	No	No
Pre‑payments		Yes	Yes	No
Other current assets		Yes	Yes	No
Total Current Assets		Sum of above
Current liabilities		Enter figure

5.6.4 Worked Examples

Example A – Manufacturing Firm (with inventory)

Item	Amount (£’000)
Cash & cash equivalents	150
Trade receivables	300
Inventory	250
Pre‑payments	20
Current liabilities	500

• Current Assets = 150 + 300 + 250 + 20 = 720
• Current Ratio = 720 ÷ 500 = 1.44
• Quick Assets = 150 + 300 + 20 = 470
• Quick Ratio = 470 ÷ 500 = 0.94
• Cash Ratio = 150 ÷ 500 = 0.30

Example B – Service‑Oriented Firm (little or no inventory)

Item	Amount (£’000)
Cash & cash equivalents	80
Trade receivables	120
Inventory	0
Pre‑payments	10
Current liabilities	200

• Current Assets = 80 + 120 + 0 + 10 = 210
• Current Ratio = 210 ÷ 200 = 1.05
• Quick Assets = 80 + 120 + 10 = 210
• Quick Ratio = 210 ÷ 200 = 1.05
• Cash Ratio = 80 ÷ 200 = 0.40

5.6.5 Interpreting the Ratios

• Benchmarking: Compare with industry averages and the firm’s own historic ratios.
• Acceptable ranges: Ratios far above the norm may indicate excess cash tied up in low‑return assets; ratios far below suggest liquidity risk.
• Operating‑cycle context: Long cycles (e.g., construction) often justify lower quick ratios because inventory and receivables are naturally higher.
• Trend analysis: A steady decline over three periods warrants investigation (e.g., rising payables, falling cash balances).
• Stakeholder perspective:
  • Creditors prefer ratios comfortably above 1.0, especially the quick ratio.
  • Investors view strong liquidity as a sign of low short‑term risk.
  • Management uses ratios to plan working‑capital financing and decide whether surplus cash can be invested.

5.6.6 Limitations of Liquidity Ratios

• Based on a single balance‑sheet date – they ignore cash‑flow timing.
• Seasonal businesses may show distorted figures if the date is not representative.
• Different accounting policies (e.g., FIFO vs. weighted‑average) affect comparability.
• Receivables may be overdue; ratios treat them as fully liquid.
• Do not differentiate between types of current liabilities (e.g., short‑term debt vs. trade payables).

Divisional	Separate product/market divisions	Flexibility	Duplication of resources
Matrix	Dual reporting – functional & project	Efficient resource use	Complex authority lines

7.2 Communication & Motivation

• Formal channels (reports, meetings) vs. informal (social media, grapevine).
• Motivation: Intrinsic vs. extrinsic; use of reward‑management systems (e.g., performance‑related pay).

7.3 HR Strategy – Hard vs. Soft

• Hard HRM: People as resources, focus on cost‑control, performance targets.
• Soft HRM: People as valuable assets, emphasis on development, empowerment, commitment.

10 Finance & Accounting (A‑Level 10)

10.1 Advanced Ratio Analysis

Category	Ratio	Formula	Interpretation
Liquidity	Current, Quick, Cash	See Section 5.6.2	Short‑term solvency.
Profitability	Gross profit margin	\(\frac{\text{Gross profit}}{\text{Sales}}\)	Production efficiency.
	Net profit margin	\(\frac{\text{Net profit}}{\text{Sales}}\)	Overall profitability.
	Return on capital employed (ROCE)	\(\frac{\text{Operating profit}}{\text{Capital employed}}\)	Efficiency of capital use.
Efficiency	Inventory turnover	\(\frac{\text{Cost of sales}}{\text{Average inventory}}\)	How quickly stock is sold.
	Receivables turnover	\(\frac{\text{Credit sales}}{\text{Average receivables}}\)	Credit control effectiveness.
Gearing	Debt‑to‑equity	\(\frac{\text{Total debt}}{\text{Total equity}}\)	Financial risk level.

10.2 Investment Appraisal

• Payback period – time to recover initial outlay.
• Net Present Value (NPV) – \(\displaystyle \sum_{t=0}^{n}\frac{C_t}{(1+r)^t}\); accept if NPV > 0.
• Internal Rate of Return (IRR) – discount rate that makes NPV = 0; compare with required rate of return.
• Accounting Rate of Return (ARR) – average profit ÷ average investment.

10.3 Financing Decisions

• Optimal capital structure – balance between debt (tax shield) and equity (financial risk).
• Dividend policy – residual, stable, or hybrid approaches.
• Cost of capital – weighted average cost of capital (WACC) calculation.

10.4 Cash Flow Statements

Three sections: Operating activities, Investing activities, Financing activities. Use the indirect method (adjust profit for non‑cash items and working‑capital changes) or the direct method (list cash receipts/payments).

10.5 Limitations of Financial Analysis

• Historical data may not predict future performance.
• Ratios can be distorted by accounting policies.
• Quantitative analysis ignores qualitative factors (brand value, management quality).

Key Take‑aways (All Levels)

1. Business success depends on the interaction of internal resources and external forces; systematic analysis (SWOT, PESTLE, Porter) guides strategic choices.
2. Effective HRM aligns people with organisational objectives through recruitment, motivation, leadership and performance management.
3. Marketing creates value by understanding customer needs, segmenting markets and delivering a coherent mix of product, price, place and promotion.
4. Operations management ensures that inputs are transformed efficiently into outputs, balancing quality, cost, speed and flexibility.
5. Financial health is assessed through a suite of ratios, budgeting, variance analysis and investment appraisal; liquidity ratios are the first line of defence against short‑term risk.
6. Always interpret quantitative results in context – consider industry norms, the firm’s operating cycle, seasonal effects and qualitative information.
7. Combine profitability, efficiency, liquidity and gearing analysis to form a comprehensive picture of a business’s performance and prospects.
