Working Capital Management: Policies, Techniques & Optimization

Core Concepts & Definitions

1. What is Working Capital?

Working capital (WC) is the difference between current assets and current liabilities: $$\text{Working Capital}=\text{Current Assets}-\text{Current Liabilities}$$

• Current Assets: Cash, inventory, accounts receivable, prepaid expenses (converted to cash within 1 year).
• Current Liabilities: Accounts payable, short-term loans, accrued expenses (due within 1 year).

Why it matters:

• Positive WC → Business can pay short-term debts.
• Negative WC → Risk of insolvency (e.g., a Kathmandu garment shop running out of cash before paying suppliers).
• Optimal WC → Balances liquidity and profitability (e.g., eSewa holds just enough cash to process transactions without hoarding idle funds).

2. Working Capital Cycle (WCC)

The time between cash outflow for production and cash inflow from sales. Shorter cycles = better efficiency.

    B --> C["Sales on Credit\n(Receivables)"]
    C --> D["Cash Inflow\n(Collection)"]
    D --> A

Key stages:

1. Cash → Inventory: Buying raw materials (e.g., a Nepalese tea factory stocking leaves).
2. Inventory → Sales: Selling on credit (e.g., Daraz shipping orders before payment).
3. Sales → Cash: Collecting payments (e.g., Ncell billing customers monthly).

Real-world tie-in:

• Pathao drivers have a daily WCC: They pay for fuel (cash outflow), earn fares (receivables), and collect cash at trip’s end.
• NTC manages WCC by billing customers monthly (longer receivables period) but paying suppliers quarterly (stretching payables).

Working Capital Policies

Businesses choose aggressive, moderate, or conservative policies based on risk tolerance.

Trade-offs:

• Aggressive: High profitability but liquidity risk (e.g., a Kathmandu retail shop running out of stock during Diwali).
• Conservative: Safe but opportunity cost (e.g., Nepal Investment Bank earning low returns on idle cash).

Working Capital Management Techniques

1. Cash Management

Goal: Minimize idle cash while ensuring payments. Techniques:

• Cash Budgeting: Forecast inflows/outflows (e.g., eSewa predicts daily transaction volumes).
• Lockbox System: Speed up collections (e.g., Ncell uses bank lockboxes for faster bill payments).
• Marketable Securities: Invest excess cash short-term (e.g., Global IME Bank parks surplus in T-bills).

Example: A Pokhara hotel expects ₹500,000 in December (peak season) but pays ₹300,000 for supplies in November. Solution: Borrow ₹200,000 short-term (aggressive policy) or keep ₹300,000 idle (conservative).

2. Inventory Management

Goal: Avoid stockouts or excess inventory. Techniques:

• Economic Order Quantity (EOQ): $$EOQ=\sqrt{\frac{2DS}{H}}$$ Where:
  • $D$ = Annual demand (units)
  • $S$ = Ordering cost per order
  • $H$ = Holding cost per unit/year

Real-world application:

• Daraz Nepal uses EOQ to order electronics (e.g., ₹50,000 worth of smartphones every 2 weeks).
• Nepal Oil Corporation balances fuel inventory to avoid shortages (high holding cost) or stockouts (lost sales).

ABC Analysis: Classify inventory by value (A = 70% value, 20% items; B = 20% value, 30% items; C = 10% value, 50% items). Example: A Kathmandu spice shop might stock:

• A-items: Cardamom (high value, tight control)
• C-items: Salt (low value, minimal tracking)

3. Receivables Management

Goal: Speed up collections without losing customers. Techniques:

• Credit Policy: Set terms (e.g., Ncell offers 30-day credit to corporate clients).
• Discounts for Early Payment: e.g., 2% discount if paid within 10 days (common in Nepal’s textile industry).
• Factoring: Sell receivables to a bank (e.g., a Pokhara garment exporter sells invoices to NIBL for immediate cash).

Example: A Lalitpur furniture maker sells ₹100,000 worth of tables on credit with 2/10, net 30 terms.

• Customer pays in 10 days: Gets ₹2,000 discount → pays ₹98,000.
• Customer pays in 30 days: Pays full ₹100,000.

Trade-off:

• Stricter credit terms → Faster cash but lost sales (e.g., small shops may avoid buying from Daraz if credit terms are harsh).

4. Payables Management

Goal: Delay payments as long as possible without damaging supplier relations. Techniques:

• Stretch Payment Terms: e.g., Nepal’s construction firms delay paying suppliers by 60–90 days.
• Supplier Negotiation: Trade discounts for early payment (e.g., Big Mart gets 5% off if it pays in 15 days instead of 30).

Risk:

• Supplier may stop credit (e.g., a Kathmandu rice mill’s supplier cuts off supply if payments are delayed too long).

Working Capital Financing

1. Short-Term Sources

2. Long-Term vs. Short-Term Financing

Rule: Match asset life with financing term.

• Short-term assets (inventory, receivables) → Short-term financing (e.g., eSewa’s daily transaction funding).
• Long-term assets (machinery) → Long-term debt/equity (e.g., Nepal Bank Limited’s 5-year loans for factories).

Violation Example: A Pokhara dairy farm takes a 5-year loan to buy milking machines (long-term asset) but uses short-term credit for daily feed purchases → high interest risk.

Working Capital and Profitability

1. Working Capital Turnover Ratio

Measures how efficiently WC generates sales. $$\text{Working Capital Turnover}=\frac{\text{Sales}}{\text{Average Working Capital}}$$ Example:

• Company A: ₹50M sales, ₹10M WC → Turnover = 5 (efficient).
• Company B: ₹50M sales, ₹25M WC → Turnover = 2 (inefficient).

Real-world:

• Nepal’s tea industry has high turnover (quick sales of perishable inventory).
• Heavy machinery firms have low turnover (long production cycles).

2. Current Ratio & Quick Ratio

Example: A Kathmandu electronics shop has:

• Current Assets: ₹5M (₹2M cash, ₹2M inventory, ₹1M receivables)
• Current Liabilities: ₹3M
• Current Ratio = 5M / 3M = 1.67 (safe).
• Quick Ratio = (2M + 1M) / 3M = 1.0 (barely liquid).

Case Study: Working Capital for a Nepali Retail Shop

Business: Shree Ram Store, a Kathmandu grocery shop with ₹5M annual sales. Current Position:

• Cash: ₹500,000
• Inventory: ₹2,000,000 (rice, pulses, spices)
• Receivables: ₹800,000 (from wholesale clients)
• Payables: ₹1,500,000 (due to suppliers in 30 days)
• Working Capital = (500K + 2M + 800K) – 1.5M = ₹1.8M

Problems:

1. Low liquidity: Quick Ratio = (500K + 800K) / 1.5M = 0.87 (risk of default).
2. High inventory: Rice spoils if not sold in 3 months (holding cost = ₹500,000/year).
3. Slow collections: 40% of receivables are 60+ days overdue.

Solutions:

1. Reduce Inventory:
   • Use EOQ to order rice in smaller, frequent batches.
   • ABC analysis: Focus on high-value items (e.g., cardamom, dry fruits).
2. Improve Receivables:
   • Offer 1% discount for payment within 7 days (instead of 30-day credit).
   • Factor 50% of receivables to NIBL for immediate cash.
3. Financing:
   • Take a ₹500,000 overdraft from Nabil Bank to cover the gap.
   • Negotiate 60-day payment terms with suppliers (stretch payables).

Result:

• New WC = (500K + 1.5M + 400K) – 1.8M = ₹1.6M (still positive but safer).
• Quick Ratio = (500K + 400K) / 1.8M = 0.5 → Problem: Still low! Fix: Sell excess inventory or take a short-term loan to boost cash.

In the Real World

1. eSewa’s Cash Flow Management

   • Idea: Liquidity optimization (holding just enough cash to process transactions).
   • How: Uses real-time cash forecasting to park excess in Nepal Rastra Bank’s short-term deposits (earning ~6% interest).
   • Risk: If too much cash is tied up in deposits, users face payment delays during peak hours (e.g., Dashain).

2. Daraz Nepal’s Inventory Turnover

   • Idea: Just-in-Time (JIT) inventory to minimize holding costs.
   • How: Partners with suppliers in China/India to ship goods only after orders are placed (reduces warehouse costs).
   • Challenge: Long lead times (30–60 days for imports) mean Daraz must pre-sell some items (e.g., Diwali gifts) to fund inventory.

3. Ncell’s Receivables Management

   • Idea: Automated billing and penalties to speed collections.
   • How:
     • Prepaid model: Customers pay upfront (no receivables risk).
     • Postpaid customers: Charged ₹50 late fee after 30 days (reduces overdue payments by 40%).
   • Impact: 90% of bills are paid on time, reducing the need for debt collection agencies.

4. Nepal Investment Bank’s Working Capital Loans

   • Idea: Seasonal financing for agriculture and retail.
   • How: Offers ₹1M–₹5M loans to Pokhara vegetable farmers during planting season (March–April) with 6% interest, repayable in harvest season (October–November).
   • Why it works: Farmers use the loan to buy seeds/fertilizer (inventory) and repay from crop sales (cash inflow).

Exam Tip

What Examiners Look For

1. Definitions with Examples:

   • Always name a Nepali business (e.g., "Like eSewa, which...").
   • Avoid vague answers: Instead of "WC is important," say:

     "Working capital ensures eSewa can process ₹500M/day in transactions without running out of liquidity, as seen during Dashain when daily payments spike by 30%."

2. Numerical Problems:

   • Always show calculations in tables:

     | Item          | Amount (₹) | Dr (₹) | Cr (₹) |
     |---------------|------------|--------|--------|
     | Cash          | 500,000    | 500,000|        |
     | Inventory     | 2,000,000  |        | 2,000,000|
     | **WC**        |            | **500,000** | **2,000,000** |
     

   • Trace the accounting cycle in exams:

3. Policy Recommendations:

   • Structure answers like this:
     1. Identify the problem (e.g., "Shree Ram Store has a quick ratio of 0.87").
     2. Calculate ratios (show work).
     3. Propose 2–3 solutions (e.g., "Reduce inventory via EOQ" + "Factor receivables").
     4. Justify (e.g., "Factoring improves cash flow by 30% but costs 12% fees").

4. Common Pitfalls:

   • Ignoring real-world context: Examiners penalize answers like "WC is important" without linking to Nepal’s economy (e.g., inflation, supply chain delays).
   • Mismatched financing: Always match asset life to financing term (e.g., don’t finance inventory with long-term debt).
   • Overlooking trade-offs: Every policy has costs and benefits (e.g., stricter credit terms → faster cash but lost sales).

5. Diagrams in Exams:

   • Draw the WCC for case studies (e.g., a Pokhara dairy farm’s cash-to-milk-to-cash cycle).
   • Use T-accounts for ledger entries (e.g., recording a bank overdraft).

Sample Exam Question & Answer

Question: "A Kathmandu garment exporter has:

• Cash: ₹2M
• Inventory: ₹8M
• Receivables: ₹5M
• Payables: ₹6M Advise on working capital management, showing calculations and policies."

Model Answer:

1. Calculate WC and Ratios:

   Working Capital = (2M + 8M + 5M) – 6M = **₹9M**
   Current Ratio = 15M / 6M = **2.5** (safe)
   Quick Ratio = (2M + 5M) / 6M = **1.17** (adequate)
   

   Issue: High inventory (₹8M) may obsolesce (fashion trends change quickly).

2. Policies:

   • Inventory:
     • Apply EOQ: If ordering cost = ₹50,000/order and holding cost = 20% of inventory value/year, calculate optimal order quantity.
     • ABC Analysis: Focus on high-value fabrics (A-items) and reduce low-value threads (C-items).
   • Receivables:
     • Offer 1% discount for payment within 10 days (current terms: net 30).
     • Factor 30% of receivables to NIBL for immediate cash.
   • Payables:
     • Negotiate 45-day terms with suppliers (currently 30 days).

3. Financing:

   • Short-term loan of ₹3M to reduce inventory risk (instead of holding excess stock).
   • Trade credit: Use supplier credit (₹6M payables) to fund 60% of inventory.

4. Impact:

   • New Quick Ratio = (2M + 3M) / (6M + 3M) = 0.86 → Problem: Still low! Solution: Sell excess inventory or take a ₹2M bank overdraft.
