52 Working Capital Management
52.1 What is Working Capital?
Working Capital (WC) is the funds required for day-to-day operations of a business. It is the difference between current assets and current liabilities (net working capital), or simply the current assets used for operations (gross working capital). Working Capital Management (WCM) is the short-term financial-management discipline ensuring sufficient liquidity for operations while maximising profitability. George Philippatos and Lawrence Schall are key textbook authors; in India, I.M. Pandey and Prasanna Chandra dominate.
| Author / body | Definition |
|---|---|
| Gerstenberg | “Working capital has ordinarily been defined as the excess of current assets over current liabilities.” |
| Shubin | “Working capital is the amount of funds necessary to cover the cost of operating the enterprise.” |
| Hoagland | “Working capital is descriptive of that capital which is not fixed; the more common use of working capital is to consider it as the difference between the book value of current assets and current liabilities.” |
| Park & Gladson | “Excess of current assets of a business over current items owed to employees and others may be called working capital.” |
| I.M. Pandey | “The investment in current assets such as cash, inventories, receivables and marketable securities.” |
52.2 Two Concepts of Working Capital
| Concept | Definition |
|---|---|
| Gross Working Capital | Total current assets — quantitative view |
| Net Working Capital | Current Assets − Current Liabilities — qualitative view |
| Permanent / Fixed WC | Minimum level needed throughout the year |
| Temporary / Variable WC | Additional WC needed during peaks |
The Tandon Committee (1974) classified WC into: - Core / Hard-core WC — permanent minimum. - Cyclical WC — varies with business cycle. - Seasonal WC — varies with seasons. - Special WC — for special needs (e.g., strikes, large orders).
52.3 Operating Cycle / Cash Conversion Cycle
The Operating Cycle = time from cash outflow (for inputs) to cash inflow (from sales). The Cash Conversion Cycle (CCC) = Operating Cycle − Payable Days.
\[\text{CCC} = \text{Inventory Days} + \text{Debtor Days} - \text{Creditor Days}\]
- Inventory Days = 365 / Inventory Turnover = (Avg Inventory / COGS) × 365.
- Debtor (DSO) Days = (Avg Debtors / Credit Sales) × 365.
- Creditor (DPO) Days = (Avg Creditors / Credit Purchases) × 365.
A shorter (or negative) CCC = stronger working-capital efficiency. Amazon runs a famous negative CCC.
52.4 Operating Cycle Approach to WC Estimation
WC = Total Operating Expenses × (Operating Cycle Days / 365)
Or sum of: - Raw material inventory days × Daily RM cost. - WIP days × Daily Production cost. - FG days × Daily COGS. - Debtor days × Daily Sales. - Less: Creditor days × Daily Purchase. - Less: Wage lag × Daily Wages.
52.5 Factors Affecting WC Requirement
- Nature of business — services (low) vs manufacturing (high) vs trading (medium).
- Scale of operations.
- Production cycle length.
- Credit policy for customers and from suppliers.
- Inventory policy.
- Seasonality of business.
- Growth and expansion plans.
- Business cycle.
- Operating efficiency.
- Profit margins.
- Dividend policy.
- Availability of credit.
- Price-level changes / inflation.
- Technology and automation.
52.6 Sources of Working Capital
| Source | Examples |
|---|---|
| Spontaneous | Trade credit, outstanding wages, accrued expenses |
| Short-term Negotiated | Bank CC, OD, working-capital loans, commercial paper, factoring, bill discounting |
| Long-term Permanent | Shares, debentures, retained earnings — for permanent WC |
52.6.1 Bank Finance Forms (India)
- Cash Credit (CC) — most common; against inventory/receivables hypothecation.
- Overdraft (OD) — current-account facility.
- Working Capital Demand Loan (WCDL).
- Bills Discounting / Purchasing.
- Letters of Credit (LCs) — trade.
- Bank Guarantees (BGs).
- Packing Credit — for exporters.
- Post-Shipment Credit.
- Factoring — through factors.
- Channel Financing.
52.7 Approaches to WC Financing
| Approach | Description | Risk-Return |
|---|---|---|
| Hedging (Matching) | Match asset maturity with financing maturity | Moderate |
| Conservative | Long-term finance covers most assets + part of short-term | Low risk, lower return |
| Aggressive | Short-term finance for part of permanent assets too | High risk, higher return |
52.8 Indian Committees on Bank Credit
- Daheja Committee 1968 — bank finance for industry.
-
Tandon Committee 1974 — three methods of WC lending:
- Method I: 75 % of WC gap (CA − CL).
- Method II: 75 % of CA − full CL.
- Method III: Excludes core CA from lending base.
- Chore Committee 1979 — bifurcation of CC into demand loan + cash credit.
- Marathe Committee 1982 — branch licensing review.
- Vaz Committee 1990 — credit appraisal.
- Nayak Committee 1991 — 20 % of turnover for SSI as WC limit.
- Kannan Committee 1997 — simplification; banks free to choose method.
Tandon Committee Method II is the standard: maximum permissible bank finance (MPBF) = 75 % of (Current Assets − Current Liabilities other than bank borrowing) − Bank Borrowing. Equivalent to: Bank finance = 75 % of Net Current Assets.
52.9 Cash Management
52.9.1 Motives for Holding Cash — Keynes (1936)
- Transaction motive — day-to-day operational needs.
- Precautionary motive — buffer against uncertainty.
- Speculative motive — opportunistic investments.
A fourth modern addition: Compensating-balance motive (bank covenants).
52.9.2 Cash-Management Models
| Model | By | Application |
|---|---|---|
| Baumol Model (1952) | William Baumol | EOQ analogue for cash — periodic top-ups |
| Miller-Orr Model (1966) | Merton Miller & Daniel Orr | Random walk with upper, lower and return points |
Baumol’s Cash EOQ: \[Q^* = \sqrt{\frac{2 \times \text{Annual cash need} \times \text{Order cost}}{\text{Interest cost}}}\]
52.9.3 Cash-Management Techniques
- Speeding up collections — Lock-box system, electronic transfers, BBPS, UPI.
- Slowing payments — Centralised disbursements, controlled payment.
- Float management — Mail float, processing float, clearing float.
- Cash budgeting — daily/weekly/monthly cash forecasts.
- Surplus deployment — money-market mutual funds, T-bills, CDs, CPs.
- Compensating balances with banks.
- Concentration banking — pooling at a single bank.
- Zero-balance accounts.
52.10 Receivables (Debtor) Management
- Credit standards — who gets credit.
- Credit terms — discount, credit period.
- Credit limits — per customer.
- Collection efforts — gentle to strict.
- Credit-monitoring.
52.10.1 Credit Analysis — 5 Cs of Credit
- Character — willingness to pay; reputation.
- Capacity — ability to repay; cash flows.
- Capital — net worth, financial strength.
- Collateral — security pledged.
- Conditions — economic environment.
52.10.2 Receivables Monitoring Tools
- Ageing Schedule — bucket receivables by days outstanding.
- Days Sales Outstanding (DSO) — Avg Receivables × 365 / Sales.
- Average Collection Period.
- Collection Effectiveness Index (CEI).
- Receivables Turnover Ratio.
- Bad-debt ratio.
52.10.3 Methods of Receivable Financing
- Bill discounting — bank purchases receivables at discount.
- Factoring — sale of receivables to a factor.
- Forfaiting — non-recourse export receivable financing.
- TReDS (Trade Receivables Discounting System) — RBI-regulated electronic platform for MSME receivables.
- Securitisation of receivables.
- Letter of Credit (LC) discounting.
52.11 Inventory Management
52.11.1 Motives for Holding Inventory
- Transaction motive — meet sales.
- Precautionary motive — buffer against demand uncertainty.
- Speculative motive — anticipate price rises.
52.11.2 Inventory Costs
- Ordering / Set-up Cost — administrative cost per order.
- Carrying / Holding Cost — storage, insurance, obsolescence, opportunity cost.
- Stock-out / Shortage Cost — lost sales, customer dissatisfaction.
52.11.3 Economic Order Quantity (EOQ) — F.W. Harris (1913)
\[Q^* = \sqrt{\frac{2 \times D \times O}{C}}\]
Where D = annual demand, O = order cost, C = carrying cost per unit per year. Developed by Ford Whitman Harris (1913) and popularised by R.H. Wilson (1934) — also called Wilson Formula.
- Constant demand.
- Constant lead time.
- Instantaneous replenishment.
- No quantity discounts.
- Single product.
- No stock-outs.
52.11.4 Inventory-Management Techniques
| Technique | Idea |
|---|---|
| EOQ / Wilson Formula | Optimal order quantity |
| Reorder Point (ROP) | Lead time × Daily usage |
| Safety Stock | Buffer against uncertainty |
| ABC Analysis | Pareto — focus on A items (high value) |
| VED Analysis | Vital / Essential / Desirable (criticality) |
| FSN Analysis | Fast / Slow / Non-moving |
| SDE Analysis | Scarce / Difficult / Easy to procure |
| HML Analysis | High / Medium / Low cost |
| JIT (Just-in-Time) | Toyota / Ohno; zero inventory |
| Kanban | Toyota pull system |
| MRP / MRP II | Materials / Manufacturing Resource Planning |
| ERP | SAP, Oracle for integrated planning |
| VMI | Vendor-Managed Inventory |
| Bullwhip-effect mitigation | Forrester effect |
ABC analysis applies the Pareto 80-20 rule: - A items: ~10 % of items but ~70 % of value — tight control. - B items: ~20 % of items, ~20 % of value — moderate control. - C items: ~70 % of items, ~10 % of value — loose control.
52.12 Liquidity vs Profitability — The WC Trade-off
- Conservative: high CA → high liquidity, low profitability (excess idle funds).
- Aggressive: low CA → low liquidity (risk of stock-out, late payments), high profitability.
- Moderate: middle path.
The CFO’s challenge: optimise rather than maximise either side.
52.13 TReDS — RBI’s Innovation for MSMEs
TReDS (Trade Receivables Discounting System) — RBI-regulated electronic platform (launched 2017) for financing trade receivables of MSMEs. Three operators: RXIL (Receivables Exchange of India Ltd, NSE-SIDBI), A.TReDS, and M1xchange.
52.14 Modern Trends in WC Management
- Real-time treasury management with APIs.
- AI-driven cash forecasting.
- Supply chain financing at scale — Reverse factoring.
- Dynamic discounting for early payment.
- Block-chain LCs and trade finance.
