Working Capital Management: Policies, Techniques & Real-World Applications

Working Capital Management: Policies, Techniques & Real-World Applications

What is Working Capital?

Working capital (WC) is the difference between current assets and current liabilities of a business. It measures a company’s short-term financial health and ability to meet immediate obligations. The formula is:

Working Capital = Current Assets – Current Liabilities

Why does it matter?

• Ensures liquidity (ability to pay bills on time).
• Supports daily operations (inventory, salaries, rent).
• Balances profitability (too much WC ties up cash; too little risks insolvency).

Components of Working Capital

Working capital consists of two broad categories:

In the Real World

1. eSewa & Khalti (Digital Payments)

   • Cash Management Idea: These apps use float management (holding just enough liquidity to process transactions) to minimize idle cash while ensuring users can pay instantly. For example, when you transfer Rs. 500 via Khalti, the app holds that amount in a reserve account until the merchant withdraws it—optimizing working capital turnover.

2. Daraz (E-Commerce Inventory)

   • Inventory Management: Daraz uses just-in-time (JIT) inventory policies to avoid overstocking. For instance, during Dashain, Daraz increases supplier orders for puja items only when sales data shows demand, reducing inventory holding costs (storage, spoilage) while keeping shelves stocked.

3. NTC (Telecom Billing)

   • Accounts Receivable (A/R) Control: NTC offers prepaid and postpaid options to manage cash flow. Postpaid users (like corporate clients) create A/R (money owed by customers), while prepaid users pay upfront, reducing credit risk. NTC’s aging schedule (tracking overdue bills) helps forecast cash inflows.

4. Pathao (Ride-Hailing Cash Flow)

   • Cash Conversion Cycle (CCC): Pathao drivers receive 80% of fares upfront (reducing A/R) and pay fuel/vehicle costs later, shortening their CCC. The company also uses dynamic pricing to balance driver payouts and liquidity during peak hours (e.g., increased fares during festivals).

Working Capital Policies

Businesses adopt three main policies to manage WC, each with trade-offs:

Key Working Capital Management Techniques

1. Cash Management

Goal: Ensure enough cash for operations while investing excess profitably. Techniques:

• Cash Budgeting: Forecast inflows/outflows (e.g., seasonal sales like Tihar shopping).
• Lockbox System: Speed up collections (used by Global IME Bank for corporate clients).
• Marketable Securities: Invest idle cash in short-term instruments (T-bills, CDs).

Worked Example: Kathmandu Retail Shop Scenario: A shop in Thamel expects Rs. 500,000 in December (festive season) but has Rs. 200,000 in fixed costs. It invests the excess in a 90-day T-bill at 8% annual interest.

• Calculation:
  • Excess cash = Rs. 500,000 – Rs. 200,000 = Rs. 300,000.
  • Interest earned = $300,000\times \frac{8\%}{4}=\text{Rs. }6,000$.
• Impact: Earns Rs. 6,000 without risk, improving cash conversion efficiency.

2. Inventory Management

Goal: Minimize costs (holding, ordering, stockout) while meeting demand. Techniques:

• Economic Order Quantity (EOQ): Orders inventory in optimal quantities.
• ABC Analysis: Classify inventory by value (e.g., Daraz’s high-value electronics vs. low-value stationery).
• Just-in-Time (JIT): Reduce holding costs (used by Nepal’s garment exporters).

Formula: EOQ $$EOQ=\sqrt{\frac{2DS}{H}}$$ Where:

• $D$ = Annual demand (units)
• $S$ = Ordering cost per order
• $H$ = Holding cost per unit per year

Worked Example: Kathmandu Electronics Scenario: A shop sells 1,200 TVs/year. Ordering cost = Rs. 500; holding cost = Rs. 200/TV/year.

• Calculation: $$EOQ=\sqrt{\frac{2\times 1,200\times 500}{200}}=\sqrt{6,000}\approx 77\text{ TVs per order}$$
• Result: Order 77 TVs every 1 month (1,200/12) to minimize costs.

3. Accounts Receivable (A/R) Management

Goal: Speed up collections and reduce bad debts. Techniques:

• Credit Policy: Set terms (e.g., Nepal’s banks offer 30–90 days for loans).
• Aging Schedule: Track overdue receivables (e.g., NTC’s postpaid billing).
• Factoring: Sell A/R to a third party (used by export firms like Nepal’s textile exporters).

Worked Example: Kathmandu Manufacturing Co. Scenario: The company sells on net 60 terms (customers pay in 60 days). Average A/R = Rs. 2,000,000; sales = Rs. 12,000,000/year.

• A/R Turnover Ratio: $$\text{Turnover}=\frac{\text{Sales}}{\text{Average A/R}}=\frac{12,000,000}{2,000,000}=6\text{ times/year}$$
• Average Collection Period (ACP): $$ACP=\frac{365}{6}\approx 61\text{ days}$$
• Analysis: ACP > credit terms (60 days) → Collections are slightly delayed. The company should tighten credit terms or offer discounts for early payment.

4. Accounts Payable (A/P) Management

Goal: Delay payments to improve cash flow (but avoid damaging supplier relations). Techniques:

• Stretch Payment Terms: Pay just before due date (e.g., retailers like Big Mart).
• Discounts: Take supplier discounts (e.g., 5/10, net 30).
• Supplier Negotiation: Agree on longer terms (e.g., 60–90 days for raw materials).

Worked Example: Kathmandu Textile Mill Scenario: The mill buys fabric at Rs. 1,000/kg with terms 2/10, net 30. It currently pays on day 30.

• Opportunity Cost: If it pays on day 10, it gets a 2% discount = Rs. 20/kg saved.
• Decision: If the mill can invest the Rs. 20/kg at 10% annual interest, it should take the discount because: $$\text{Interest on Rs. 20 for 20 days}=20\times \frac{10\%}{365}\times 20\approx \text{Rs. }0.11\text{ (less than Rs. 20)}$$

Cash Conversion Cycle (CCC)

The CCC measures how long it takes to convert inventory into cash from sales. The formula is:

$$CCC=\text{Inventory Period}+\text{Receivables Period}-\text{Payables Period}$$

Components:

1. Inventory Period = $\frac{\text{Average Inventory}}{\text{Cost of Goods Sold (COGS)}}\times 365$
2. Receivables Period = $\frac{\text{Average A/R}}{\text{Sales}}\times 365$
3. Payables Period = $\frac{\text{Average A/P}}{\text{COGS}}\times 365$

Worked Example: Nepal Food Industries (NFI) Data:

• Average inventory = Rs. 500,000; COGS = Rs. 6,000,000/year.
• Average A/R = Rs. 800,000; Sales = Rs. 8,000,000/year.
• Average A/P = Rs. 400,000.

Calculations:

1. Inventory Period = $\frac{500,000}{6,000,000}\times 365=30.4\text{ days}$
2. Receivables Period = $\frac{800,000}{8,000,000}\times 365=36.5\text{ days}$
3. Payables Period = $\frac{400,000}{6,000,000}\times 365=24.3\text{ days}$
4. CCC = 30.4 + 36.5 – 24.3 = 42.6 days

Interpretation:

• NFI takes 42.6 days to convert inventory into cash.
• Benchmark: Faster CCC = better liquidity. Compare with competitors (e.g., Unilever Nepal’s CCC).

Common Pitfalls & How to Avoid Them

1. Overtrading (Excessive Growth)

   • Problem: Expanding too fast without enough WC (e.g., Nepal’s failed startups).
   • Solution: Use pro forma financial statements to project WC needs.

2. Underestimating Seasonality

   • Problem: Ignoring cash flow fluctuations (e.g., agricultural businesses in monsoon vs. winter).
   • Solution: Maintain a seasonal cash reserve.

3. Poor Credit Control

   • Problem: Bad debts (e.g., NTC’s unpaid postpaid bills).
   • Solution: Implement credit scoring and aging reports.

Exam Tip

How to Score Full Marks in TU/PU Exams

1. Definitions & Formulas

   • Always define key terms (e.g., "Working capital is the difference between current assets and current liabilities...").
   • Memorize formulas like EOQ, CCC, and A/R turnover but show all steps in calculations.

2. Numerical Problems

   • Label every step (e.g., "Step 1: Calculate Inventory Period").
   • Use real numbers (e.g., "Assume a shop in Lalitpur with...").
   • Interpret results (e.g., "A CCC of 45 days is better than 60 days because...").

3. Case Studies

   • Relate to Nepali businesses (e.g., "Like Nabil Bank’s loan policies...").
   • Compare policies (e.g., "Aggressive vs. conservative WC for a startup vs. a bank").

4. Diagrams & Tables

   • Draw T-accounts for ledger entries (e.g., inventory purchase).
   • Use tables to compare policies (aggressive/moderate/conservative).

5. Common Exam Questions

   • Describe: "Explain the significance of cash management." → Use 3 bullet points with examples.
   • Calculate: Always show workings (e.g., EOQ, CCC).
   • Advise: "Recommend a WC policy for a Kathmandu restaurant." → Justify your choice (e.g., "Moderate policy due to seasonal demand").

Sample Exam Question & Answer

Question: *"The ABC Retail Shop in Kathmandu has the following data:

• Average inventory = Rs. 1,500,000
• COGS = Rs. 18,000,000/year
• Average A/R = Rs. 2,000,000
• Sales = Rs. 24,000,000/year
• Average A/P = Rs. 1,000,000 Calculate the Cash Conversion Cycle (CCC) and advise whether the shop should improve its inventory or receivables management."*

Model Answer:

1. Calculate Inventory Period: $$\frac{1,500,000}{18,000,000}\times 365=30.4\text{ days}$$

2. Calculate Receivables Period: $$\frac{2,000,000}{24,000,000}\times 365=30.4\text{ days}$$

3. Calculate Payables Period: $$\frac{1,000,000}{18,000,000}\times 365=20.3\text{ days}$$

4. CCC: $$30.4+30.4-20.3=40.5\text{ days}$$

5. Advice:

   • The CCC of 40.5 days is high (benchmark: 30–40 days for retail).
   • Priority: Improve inventory management (30.4 days is long for retail). Suggestions:
     • Adopt JIT inventory to reduce holding costs.
     • Use ABC analysis to focus on high-value items (e.g., electronics).
   • Secondary: Tighten credit policy (offer discounts for early payment).
