Working Capital Management: Liquidity, Efficiency & Cash Flow

TAKEAWAYS:

• Working capital is the difference between current assets and current liabilities, and its management ensures a firm can meet short-term obligations while avoiding excess idle funds.
• The working capital cycle (cash-to-cash conversion) is critical: Cash → Inventory → Receivables → Cash, and its length directly impacts profitability.
• Financing strategies (short-term vs. long-term) must align with the firm’s cash flow needs—over-trading risks insolvency, while under-trading wastes potential revenue.
• Inventory management (EOQ, ABC analysis) and credit policies (terms like 2/10 net 30) directly affect working capital efficiency and customer retention.
• Cash flow forecasting uses techniques like the percentage-of-sales method to predict liquidity needs and avoid stockouts or overstocking.
• Optimal working capital balances risk (insolvency) and opportunity cost (lost sales due to tight liquidity), often modeled via financial ratios (current ratio, quick ratio).

1. Definitions and Core Concepts

Working capital (WC) is the net amount of a firm’s short-term assets (cash, receivables, inventory) minus its short-term liabilities (payables, short-term debt). It measures a company’s liquidity—its ability to cover day-to-day expenses without selling long-term assets.

Key Terms

• Net Working Capital (NWC): $$\text{NWC}=\text{Current Assets}-\text{Current Liabilities}$$ A positive NWC means the firm can pay its short-term debts; negative NWC signals potential liquidity crises.

• Working Capital Cycle (Cash Conversion Cycle, CCC): The time between cash outflow (purchasing inventory) and cash inflow (receiving payment from customers). Shorter cycles improve efficiency. $$\text{CCC}=\text{Inventory Period}+\text{Receivables Period}-\text{Payables Period}$$

• Over-Trading vs. Under-Trading:

  • Over-trading: Financing operations with short-term debt, risking insolvency if sales drop.
  • Under-trading: Holding excessive cash/inventory, wasting potential revenue.

2. Working Capital Needs and Financing Strategies

Firms require working capital to:

• Maintain operational continuity (pay suppliers, wages, utilities).
• Take advantage of discounts (e.g., 2/10 net 30 in Nepal’s supply chains).
• Meet unexpected demands (e.g., sudden Daraz order surges).

Financing Working Capital

Supplier: "2/10 net 30"
- Buy now, pay 98% of invoice in 10 days → **2% discount**.
- Pay full amount in 30 days if no discount taken.

Example: A Kathmandu retailer buys Rs 500,000 worth of goods. Option 1: Pay Rs 490,000 in 10 days (saves Rs 10,000). Option 2: Pay Rs 500,000 in 30 days (no discount). Trade-off: Cash flow vs. savings.

A. Inventory Management

Inventory ties up capital; inefficient management leads to stockouts (lost sales) or obsolete stock (wasted funds).

Key Strategies:

1. Economic Order Quantity (EOQ): Minimizes ordering costs and holding costs. $$\text{EOQ}=\sqrt{\frac{2DS}{H}}$$ Where:

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

   Example: A Daraz warehouse stocks 10,000 units/year of a product. Ordering costs Rs 500/order; holding cost is Rs 20/unit/year. $$\text{EOQ}=\sqrt{\frac{2\times 10,000\times 500}{20}}=\sqrt{500,000}=707\text{ units}$$ Interpretation: Order 707 units every ~14 days to minimize costs.

2. ABC Analysis: Classifies inventory into A (high value, low volume), B (medium), C (low value, high volume) to prioritize control.

   Category	% of Items	% of Value	Control Strategy
   A	10%	70%	Strict tracking, JIT.
   B	20%	20%	Moderate control.
   C	70%	10%	Bulk ordering, minimal checks.

A: 10% items, 70% value (e.g., electronics)
B: 20% items, 20% value (e.g., stationery)
C: 70% items, 10% value (e.g., packaging)

B. Accounts Receivable (AR) Management

AR represents uncollected sales revenue. Poor collection policies hurt cash flow.

Strategies:

• Credit Policy: Define terms (e.g., "net 30") and credit limits.
• Discounts for Early Payment: Encourage faster collections (e.g., 1% discount if paid in 10 days).
• Factoring: Sell receivables to a third party for immediate cash (common in Pathao’s rider payments).

Example: A Pathao driver earns Rs 5,000/month but waits 30 days for payment. If Pathao factors receivables, the driver gets Rs 4,700 upfront (with a 6% fee), improving liquidity.

Red flag: >90 days receivables may indicate credit risks.

4. Managing Current Liabilities

Current liabilities (e.g., trade payables, short-term loans) should be managed to delay payments (to preserve cash) while avoiding penalties.

Strategies:

• Cash Discounts: Take discounts to reduce payables (e.g., pay Rs 490,000 in 10 days instead of Rs 500,000 in 30 days).
• Negotiate Terms: Extend payable periods (e.g., from 30 to 60 days) if suppliers agree.
• Just-in-Time (JIT): Reduce inventory by receiving goods only when needed (used by Daraz for perishable goods).

Supplier → [Delivery only when needed] → Retailer → Customer

Benefit: Lowers holding costs but requires reliable suppliers.

5. Cash Flow Forecasting

Predicting future cash flows ensures the firm can meet obligations. Methods include:

A. Percentage-of-Sales Method

Assumes current assets/liabilities grow proportionally with sales. $$\text{Projected WC}=(\text{Current Ratio}-1)\times \text{Projected Sales}$$

Example: A Kathmandu retail shop has:

• Current Ratio = 1.5
• Projected Sales = Rs 12,000,000
• Current Liabilities = Rs 4,000,000 $$\text{Projected WC}=(1.5-1)\times 12,000,000=\text{Rs }6,000,000$$

B. Cash Budget

Tracks inflows (sales, loans) and outflows (payroll, rent) over a period (e.g., quarterly).

Use: Identifies months with cash deficits (need for short-term loans) or surpluses (investment opportunities).

Cash Balance (Rs)

500,000 |       _______
       |      /
       |     /
       |____/
       Jan Feb Mar

Trend: Rising cash balance suggests improving liquidity.

6. Working Capital Ratios

Ratios assess liquidity and efficiency:

Example: A Ncell store has:

• Current Assets = Rs 2,000,000
• Current Liabilities = Rs 1,000,000
• Inventory = Rs 500,000
• COGS = Rs 1,200,000
• Average Receivables = Rs 300,000
• Annual Sales = Rs 3,600,000 $$\text{Current Ratio}=2,000,000/1,000,000=2.0(\text{Good})$$ $$\text{Quick Ratio}=(2,000,000-500,000)/1,000,000=1.5(\text{Acceptable})$$ $$\text{Inventory Turnover}=1,200,000/500,000=2.4(\text{Slow; may need EOQ review})$$

7. Optimal Working Capital

Optimal WC balances:

• Risk of insolvency (too little WC).
• Opportunity cost (too much WC wastes capital).

Determinants:

• Industry norms (e.g., retail needs higher WC than manufacturing).
• Firm size (larger firms can afford more WC).
• Economic conditions (recessions → higher WC needs).

Example: A Nepalese bank (e.g., Global IME) holds higher WC than a Ncell store because banks must always have liquid assets to meet depositor withdrawals.

Too Little WC → Optimal WC → Too Much WC
| Insolvency Risk | Balanced | Wasted Capital |

Trade-off: Banks aim for liquidity safety; startups prioritize growth over safety.

In the Real World

1. eSewa/Khalti (Digital Payments):

   • Idea: Cash flow forecasting ensures eSewa/Khalti can cover transaction volumes without running out of funds.
   • How: Uses real-time analytics to predict peak payment times (e.g., salary days) and pre-position liquidity.
   • Worked Example: On Baisakh 15, eSewa expects Rs 500 million in transactions. It borrows short-term from banks to cover the spike, then repays once funds clear.

2. Daraz (E-commerce):

   • Idea: Inventory management (ABC analysis + EOQ) prevents stockouts during festivals (e.g., Dashain).
   • How: Daraz stocks A-items (high-value, low-volume) in warehouses and C-items (bulk, low-value) near distribution centers.
   • Worked Example: During Tihar, Daraz’s EOQ for firecrackers is 5,000 boxes (calculated based on past demand). If sales exceed, it orders additional stock via suppliers.

3. NTC/Ncell (Telecom):

   • Idea: Accounts receivable management ensures timely collections from subscribers.
   • How: NTC offers discounts for prepaid top-ups (e.g., 10% off on Rs 1,000 top-ups) to encourage early payments.
   • Worked Example: A Ncell customer owes Rs 500. If paid within 7 days, they get a 5% discount (Rs 25 savings). This reduces Ncell’s receivables period from 30 to 7 days.

Exam Tip

This unit is highly numerical and tests:

1. Calculations: EOQ, CCC, working capital ratios, cash budgets.

   • Example: You’ll see a balance sheet and be asked to compute NWC or CCC.
   • Tip: Always round to 2 decimal places for ratios (e.g., 1.50, not 1.5).

2. Conceptual Questions: Differentiate short-term vs. long-term financing, explain trade-offs in credit policies, or analyze ABC analysis for a given scenario.

   • Example: "Why does a retail store like Pathao need higher working capital than a manufacturing firm like Ncell?"
   • Answer Structure:
     • Pathao has higher receivables (customers pay post-delivery).
     • Ncell has long-term contracts (prepaid plans reduce receivables risk).
     • Key Point: Industry-specific needs determine WC levels.

3. Application-Based: Link theories to Nepali businesses (e.g., banks, e-commerce, telecom).

   • Example: "How would eSewa use cash flow forecasting to handle a sudden Rs 2 billion transaction surge?"
   • Answer:
     • Step 1: Analyze historical data to predict peak periods (e.g., salary days).
     • Step 2: Pre-borrow from banks or use liquidity lines of credit.
     • Step 3: Optimize receivables by offering discounts for early payments.

4. Graphs/Tables: Expect working capital cycle diagrams, cash budget tables, or ratio analysis comparisons.

   • Tip: Always label axes and unitize (e.g., "Days" for CCC, "Rs" for cash flows).

Final Advice:

• Memorize formulas (EOQ, CCC, ratios) but practice calculations—exams love numericals.
• Relate to Nepali examples (eSewa, Daraz, Ncell) to score higher.
• For essays, use real-world trade-offs (e.g., "Why does a startup like Pathao take trade credit but a bank like Global IME avoids it?").
