Working Capital and Improving Liquidity (Edexcel A-Level Business): Revision Notes
Working Capital and Improving Liquidity
What is working capital?
Working capital (also called circulating capital) represents the funds available to a business for its day-to-day operations. It is the financial cushion that allows a business to pay wages, utility bills, purchase raw materials, and meet other short-term obligations.
The formula for calculating working capital is:
Components of working capital
Current assets are liquid resources that can be converted into cash within one year:
- Cash and cash equivalents – money in the bank or physical notes and coins
- Inventories (stock) – raw materials, work-in-progress, and finished goods
- Trade receivables (debtors) – money owed by customers who bought on credit
Current liabilities are short-term debts that must be paid within one year:
- Trade payables (creditors) – money owed to suppliers
- Loans and borrowings – short-term bank loans and overdrafts
- Current tax liabilities – tax payments due within the year
Why working capital matters
The level of working capital provides important signals about business health. A business struggling financially or facing closure typically has low working capital. When analysing a balance sheet, low working capital should act as a warning sign that the business may be experiencing difficulties.
The challenge is maintaining an optimal level – enough to operate smoothly, but not so much that money sits idle earning no return. Working capital needs vary significantly between industries and business types.
Measuring liquidity with ratios
Liquidity ratios help assess whether a business has sufficient liquid resources to meet its short-term obligations. The two key ratios are the current ratio and the acid test ratio.
Current ratio
The current ratio measures a business's ability to pay its short-term debts using its current assets.
Formula:
Interpretation:
- Ideal range: Between 1.5:1 and 2:1
- Below 1.5:1 – suggests insufficient working capital, possibly indicating over-borrowing or overtrading
- Above 2:1 – suggests excessive funds tied up unproductively (e.g., earning no return on stock holdings)
However, industry context matters. Retailers often operate successfully with current ratios of 1:1 or below because they hold fast-selling stock and generate immediate cash from sales.
Acid test ratio (quick ratio)
The acid test ratio provides a more stringent liquidity measure by excluding inventories from current assets.
Formula:
Why exclude inventories?
- No guarantee stock can be sold quickly
- Stock may become obsolete or deteriorate
- Physical stock cannot pay bills – only cash can
Interpretation:
- Below 1:1 – current assets (excluding stock) do not cover current liabilities, potentially indicating problems
- However, like the current ratio, acceptable levels vary by industry
- Retailers with strong cash flows may operate comfortably below 1:1
Worked Example: Kingham plc
Let's examine the liquidity position of Kingham plc, a clothing chain store, using its 2014 balance sheet data.
Given information (2014):
- Current assets: £42.5m
- Current liabilities: £36.7m
- Inventories: £32.1m
Calculations:
Analysis:
Both ratios appear low in 2014. The current ratio sits below the ideal 1.5:1 threshold, and the acid test ratio falls well short of 1:1. This suggests potential liquidity constraints. The position has deteriorated from 2013, with the acid test ratio experiencing a particularly sharp decline.
However, context is crucial. As a clothing retailer, Kingham plc generates mostly cash sales. This means the business can operate safely with lower liquidity ratios than manufacturers or businesses offering extensive credit terms. The high inventory level (£32.1m) reflects the nature of retail operations where stock forms a major current asset.
Managing working capital effectively
Different businesses require different levels of working capital based on several factors.
Factors affecting working capital needs
Size of business
Larger businesses typically require more working capital because sales volume creates proportionally greater needs for stock, trade credit, and cash. Expanding businesses face growing working capital requirements as they scale operations.
Stock levels
Working capital needs vary dramatically by industry:
- A window cleaning business carries minimal stock
- A retailer holds substantial inventory
- Businesses using just-in-time (JIT) techniques maintain lower stock levels
- Higher stock holdings increase working capital requirements
Debtors and creditors
The time lag between purchasing stock on credit and receiving payment for finished products significantly influences working capital levels. For example, a builder may need high working capital because months might pass between starting a project and receiving final payment from clients.
Conversely, large supermarket chains often operate with negative working capital (current assets less than current liabilities). This unusual situation occurs because:
- They purchase stock from suppliers on 30-day credit terms
- Stock sells within days of delivery
- Customers pay cash immediately
- The result: large amounts owed to suppliers but minimal debts owed to the business
Few businesses can operate with negative working capital. The standard guideline suggests businesses need approximately twice as many current assets as current liabilities (current ratio between 1.5:1 and 2:1) to operate safely.
Problems with inadequate working capital
When current assets are too low or current liabilities too high, businesses face operational difficulties:
Stock-related problems:
- Insufficient raw materials can halt production when items run out
- Low finished goods inventory prevents fulfilling orders on time
- Missed sales opportunities damage reputation and revenue
Cash shortages:
- Unable to pay bills when due
- Supplier relationships deteriorate
- Risk of legal action from creditors
Excessive trade credit:
- Owing too much to creditors creates pressure
- May be unable to pay invoices on time
- Suppliers might withdraw credit facilities or stop deliveries
Problems with excessive working capital
Too much working capital (current assets too high, current liabilities too low) also creates inefficiencies:
Stock costs:
- Physical costs – storage space, handling, warehousing
- Insurance costs – protecting stock against damage or loss
- Shrinkage – theft, usually by employees, reduces inventory value
- Financial costs – money tied up in stock could reduce borrowing and save interest
- Opportunity cost – funds could generate returns elsewhere
Excess cash:
- Cash typically earns low interest rates in current accounts
- Could be used to repay debts and save interest charges
- Could be invested in higher-return long-term investments
The critical importance of cash
Cash is the most liquid of all business assets, comprising physical notes and coins plus bank deposits. While cash forms part of working capital, it is distinct from it – working capital includes other current assets like trade receivables that cannot directly pay bills.
Why businesses fail
According to a Confederation of British Industry (CBI) survey, 21% of business failures result from poor cash flow or lack of working capital. Remarkably, businesses can fail even during good trading conditions when they offer viable products with market demand and potential profitability. The most common cause: running out of cash.
This highlights a fundamental business principle: profitability does not guarantee survival – cash flow does. A business can show paper profits yet collapse if it cannot convert those profits into cash quickly enough to meet immediate obligations.
Strategies to improve liquidity
When businesses experience liquidity problems, survival becomes the priority over profit maximization. The goal is to increase current assets, reduce current liabilities, or both. Here are the key strategies:
Use of overdraft facilities
Most businesses maintain overdraft facilities with their banks, providing a flexible source of short-term finance.
How it works:
- Business negotiates an overdraft limit (e.g., £5,000)
- Can borrow up to that limit as needed
- If currently borrowing £3,000, could access an additional £2,000
Limitations:
- If already at the overdraft limit, must negotiate an increase
- Banks may refuse to increase limits for businesses experiencing difficulties
- Banks will not lend to businesses at risk of imminent failure
Negotiate additional loans
Short-term loans can inject immediate cash when facing temporary liquidity constraints. Long-term loans spread repayments over extended periods with smaller instalments, easing cash flow pressure.
Challenges:
- Once cash shortages become known, lenders grow reluctant to provide finance
- Banks fear lending to potentially failing businesses
- May require additional security or charge higher interest rates
Encourage cash sales and reduce stock
Cash sales strategies:
- Offer significant discounts for immediate cash payment
- Particularly effective for retailers with regular customer transactions
Stock reduction:
- Sell raw materials, components, or semi-finished goods for cash
- Offer clearance sales to move stock quickly, even below cost if necessary
- Simply reduce stock holdings to free up tied cash
Risks:
- Discounting reduces profit margins
- Inadequate stock levels may prevent fulfilling orders
- Production could halt if raw materials run out
Sale and leaseback
How it works:
- Sell assets (property, machinery, vehicles) to specialist companies
- Immediately lease the assets back
- Business receives cash injection while retaining asset use
Advantages:
- Raises substantial cash quickly
- Maintains operational capacity
Disadvantages:
- Takes time to arrange agreements
- Expensive funding method in the long term
- Loses asset ownership and flexibility
Alternatively, businesses can simply sell unnecessary assets for cash without leasing them back.
Only make essential purchases
During cash crises, strict financial discipline becomes essential:
Postpone or cancel unnecessary spending:
- Purchase resources only when absolutely necessary
- Delay all non-essential capital expenditure
- Review all planned purchases critically
Delay payments:
- Hold onto cash longer by postponing payments
- Only pay when creditors apply pressure
- Maintains cash in the business temporarily
Risks:
- Damages supplier relationships
- Creditors may take legal action
- May lose credit facilities for future purchases
Extend credit with selected suppliers
Businesses can conserve cash by negotiating longer payment terms with suppliers.
Example:
- Extend standard 30-day credit terms to 60 days
- Keeps cash in the business for an additional month
- Particularly useful during temporary cash flow difficulties
Risks:
- Delaying too long damages supplier relationships
- Suppliers may withdraw credit facilities entirely
- Future deliveries might be refused
- Reputation in the industry suffers
Reduce personal drawings
Business owners who regularly withdraw cash for personal use can improve liquidity by reducing drawings.
Application:
- Most relevant for sole traders, partnerships, and small private companies
- Owners retain only essential cash for living expenses
- Quick method to stop cash leaving the business
Limitations:
- Only viable if owners have alternative income sources
- Cannot reduce below reasonable living expense levels
- May affect owner motivation and commitment
Introduce fresh capital
Owners can inject new equity capital to improve cash flow.
Sources:
- Personal savings – owners invest their own money
- Personal loans – owners borrow against personal assets (property, investments)
- New partners – bring in additional partners with capital contributions
- Share issues – larger companies can sell new shares (though attracting investors when struggling is difficult)
Reality:
Extremely difficult to attract external investment when experiencing liquidity problems. Current owners typically must provide additional capital themselves. This represents a last resort for many small businesses.
Case Study: Euro Disney
In 2014, Euro Disney (operating Disneyland Paris) faced severe liquidity problems. The company needed finance to service its €1.75 billion debt burden, which had created constant financial pressure since opening.
Solution implemented:
- The Walt Disney Company (main shareholder) backed a €420 million rights issue
- Converted €600 million of existing loans into equity
- Total injection: over €1 billion
Results:
- Expected to boost cash flow by approximately €800 million over ten years
- Reduced debt servicing burden
- Improved liquidity position substantially
This case illustrates how major liquidity problems often require combinations of strategies – here, both fresh equity capital and debt-to-equity conversion.
Key Points to Remember:
Key liquidity concepts:
- Working capital = Current assets – Current liabilities. Adequate working capital is essential for day-to-day operations and business survival
- Current ratio (ideal 1.5:1 to 2:1) and acid test ratio (excluding inventories) measure a business's ability to meet short-term obligations, but acceptable levels vary by industry
- Cash is the most liquid asset – 21% of business failures result from poor cash flow, not necessarily lack of profitability
Working capital management:
- Different businesses need different working capital levels based on size, industry, stock requirements, and debtor/creditor terms
- Too little working capital causes operational problems (stock shortages, unpaid bills, production halts)
- Too much working capital creates inefficiency (storage costs, insurance, opportunity costs, shrinkage)
Improving liquidity when problems arise:
- Multiple strategies exist: overdrafts, loans, stock reduction, sale and leaseback, delaying payments, reducing drawings, and fresh capital
- Each method has advantages and limitations – successful businesses often combine several approaches
- Prevention through effective cash flow forecasting and budgeting is better than crisis management
