How does the cash conversion cycle work and why is working capital management important?
I know working capital is current assets minus current liabilities, but I don't fully understand the cash conversion cycle and how companies optimize it. Can someone walk me through this with an example?
Working capital management is about ensuring a company has enough liquidity to operate while minimizing idle cash. The cash conversion cycle (CCC) is the key metric.
Cash Conversion Cycle Formula:
CCC = Days Inventory Outstanding (DIO) + Days Sales Outstanding (DSO) - Days Payable Outstanding (DPO)
Example -- Summit Outdoor Gear:
| Metric | Value |
|---|---|
| COGS | $3,000,000 |
| Revenue | $5,000,000 |
| Average Inventory | $600,000 |
| Average Receivables | $500,000 |
| Average Payables | $400,000 |
Calculations:
- DIO = (Average Inventory / COGS) x 365 = ($600K / $3M) x 365 = 73 days
- DSO = (Average Receivables / Revenue) x 365 = ($500K / $5M) x 365 = 36.5 days
- DPO = (Average Payables / COGS) x 365 = ($400K / $3M) x 365 = 48.7 days
- CCC = 73 + 36.5 - 48.7 = 60.8 days
Summit has to finance 60.8 days of operations from its own resources before collecting cash from customers.
Optimization Strategies:
| Strategy | Effect on CCC | Risk |
|---|---|---|
| Reduce inventory levels | Lower DIO | Potential stockouts |
| Tighten credit terms | Lower DSO | May lose customers |
| Negotiate longer payment terms | Higher DPO | Supplier relationship strain |
| Use JIT inventory | Lower DIO | Supply chain vulnerability |
Negative CCC Example: Some companies like large retailers collect cash from customers before paying suppliers. If DPO > DIO + DSO, the CCC is negative -- the company is essentially financed by its suppliers.
Why It Matters:
- A rising CCC means the company needs more working capital financing
- A falling CCC indicates improving operational efficiency
- Comparing CCC across competitors reveals who manages their cash cycle best
Exam Tip: The CFA exam may give you partial data and ask you to calculate missing components, or compare CCC across two companies in different industries.
