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.

TipWorking definitions
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

TipGross vs Net WC
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
NoteTandon Committee classification

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.

TipCCC formula

\[\text{CCC} = \text{Inventory Days} + \text{Debtor Days} - \text{Creditor Days}\]

  • 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

TipWC requirement — Operating Cycle Method

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

TipDeterminants of 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

TipSources of WC financing
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)

TipBank finance for WC
  • 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

TipThree approaches
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

TipKey RBI committees on WC bank finance
  • 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.
NoteTandon Method II — most commonly applied

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)

TipKeynes’ three motives
  • 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

TipTwo classic 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

TipCash-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

TipFive-pillar credit policy
  • 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

TipThe 5 Cs of credit assessment
  • 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

TipReceivables 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

TipReceivable 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

TipThree motives
  • Transaction motive — meet sales.
  • Precautionary motive — buffer against demand uncertainty.
  • Speculative motive — anticipate price rises.

52.11.2 Inventory Costs

TipInventory cost categories
  • 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.

TipEOQ assumptions
  • Constant demand.
  • Constant lead time.
  • Instantaneous replenishment.
  • No quantity discounts.
  • Single product.
  • No stock-outs.

52.11.4 Inventory-Management Techniques

TipInventory-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
NoteABC Pareto

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

TipConservative vs Aggressive WC policy
  • 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.
