This lesson introduces the core concepts of cash management, liquidity, and the working capital cycle.

5.1 The Nature of Cash Flows
An organisation’s cash flows are the lifeblood of its operations. Cash flows can be unpredictable, affected by a wide range of internal and external factors. A key role of treasury is to forecast these cash flows accurately to ensure that the organisation can meet its obligations .

5.2 The Operating Cycle and Cash Conversion Cycle
The operating cycle is the time it takes for a company to convert its investments in inventory and other resources into cash flows from sales . The cash conversion cycle (CCC) is a more precise measure, calculating the number of days between a company paying for its inventory and receiving cash from its customers. It is calculated as:
CCC = Days Sales Outstanding (DSO) + Days Inventory Outstanding (DIO) - Days Payables Outstanding (DPO)
A shorter cash conversion cycle is generally desirable, as it indicates that a company can convert its investments into cash more quickly, reducing the need for external financing.

5.3 The Importance of Liquidity
Liquidity is the ability of an organisation to meet its short-term financial obligations as they fall due . Managing liquidity is the most fundamental objective of the treasury function. A shortage of liquidity can lead to insolvency, even if the organisation is profitable. A key concern is that clients now have instant access to their funds through digital channels, making their cash withdrawals faster and less predictable . Therefore, robust forecasting and contingency planning are essential.

5.4 Key Cash Management Concepts
Several key concepts underpin effective cash management :

• Float: The time lag between a payment being initiated and funds actually being debited from the payer’s account or credited to the payee’s account.

• Cash Concentration: The process of sweeping surplus funds from subsidiary accounts into a central account to maximise investment returns and reduce borrowing costs.

• Notional Pooling: A method of interest optimisation where balances of multiple accounts are netted for interest calculation purposes, without physically moving the funds.

• Payment Systems: The instruments and channels used to transfer value (e.g., wires, ACH, cheques) .
