Liquidity sources and liquidity ratios

Liquidity is a company's ability to meet its short-term obligations. It relies first on cash, borrowing capacity and operating cash flow; in a crisis it turns to costlier secondary sources such as cutting dividends, issuing equity or selling assets. Drags slow cash in, pulls speed cash out. Current, quick and cash ratios measure it.

What is liquidity, and where does it come from?

Liquidity is a company’s ability to meet its short-term obligations. For one asset or liability, it means how close it is to cash or settlement: cash is already cash, receivables take weeks to collect, inventory takes longer, and a payable due in five days is more pressing than a lease payment due next month. A company’s overall liquidity depends on the amounts and the liquidity of its short-term assets and liabilities, which follow from its business model and its cash conversion cycle.

The company has two tiers of sources to call on.

Where liquidity comes from
Sources of liquidityways to find cash for short-term obligations
  • Primary sources Memorize normal course, no damage to operations
    • Cash and marketable securities Memorize on hand, sold quickly at little loss
    • Borrowing Memorize bank lines, bonds, suppliers trade credit
    • Cash flow from the business Memorize the main long-run source
  • Secondary sources Memorize stress, costly, often a warning sign
    • Suspend dividends, delay capital spending Memorize preserve cash now
    • Issue equity Memorize dilutes existing owners
    • Renegotiate contracts Memorize debt, leases, customer and supplier terms
    • Sell assets Memorize liquidation costs apply
    • Bankruptcy protection Memorize reorganize and keep operating

Primary liquidity sources are the cash the company can reach in the normal course without hurting operations:

  • Cash and marketable securities on hand, which can be used or sold quickly with little loss.
  • Borrowing from banks, bondholders or suppliers (trade credit). It helps now but creates a debt to repay.
  • Cash flow from the business. It takes time to arrive, but for a profitable company it is the main long-run source. A firm with a supplier bill of 25 due in three months that expects 70 of operating cash over those months needs neither its cash balance nor new loans to pay it.

Secondary liquidity sources are used when the primary sources are not enough. They cost more and often signal a deteriorating position: suspending or cutting dividends, delaying or cutting capital spending (which can damage long-term value), issuing equity (dilution), renegotiating contracts (refinancing short-term debt into long-term, seeking concessions on interest, rent or lease payments, or changing terms with customers and suppliers), selling assets, and filing for bankruptcy protection to reorganize.

Cash-like assets plus receivables cover current liabilities. Each ratio drops a less liquid asset, so current ≥ quick ≥ cash.

Show working

Current liabilities = 54 + 16 + 40 = 110.

Cash ratio = (cash + marketable securities) ÷ current liabilities = (30 + 20) ÷ 110 = 0.45.

Quick ratio = (cash + securities + receivables) ÷ current liabilities = 130 ÷ 110 = 1.18.

Current ratio = current assets ÷ current liabilities = 210 ÷ 110 = 1.91.

Trap: putting inventory into the quick ratio would give 1.84.

The more of your current assets are cash-like, the safer you are.

Exam tip Ask “is this part of normal business or an emergency step?” Normal means primary. Emergency means secondary.

How is cash flow from the business measured?

Cash flow from operations (CFO) is the cash profit of the main business activities:

Cash flow from operations Use it
CFO=Cash from customers+Interest and dividends received−Cash paid to employees and suppliers−Taxes paid−Interest paid\text{CFO} = \text{Cash from customers} + \text{Interest and dividends received} - \text{Cash paid to employees and suppliers} - \text{Taxes paid} - \text{Interest paid}

CFO does not allow for the investments the company must make to keep operating or to grow. Free cash flow (FCF) does.

Free cash flow Use it
FCF=CFO−Investment in long-term assets\text{FCF} = \text{CFO} - \text{Investment in long-term assets}
Rearrange itFree cash flow: solve for any input
The question asks for
A company reports cash flow from operations of 520.00 and investment in long-term assets of 310.00. Its free cash flow is closest to:

520.00 − 310.00 = 210.00

Free cash flow, FCF210.00

On your calculator
  1. 520−310=210
  1. 520ENTER310−210

ENTER enter (on the HP, puts the number on the stack)

A variant of free cash flow adds back the interest paid, to measure the cash available to lenders and shareholders together. It returns later in the curriculum.

What does it cost to raise cash in a crunch?

Selling an asset quickly rarely yields full value. Liquidation costs are the fees, commissions and price discount that come with a quick sale. Net proceeds are the fair value less those costs, summed over everything sold.

Net proceeds after liquidation costs Use it
Net proceeds=∑iFVi×(1−ci)\text{Net proceeds} = \sum_i \text{FV}_i \times (1 - c_i)
Go deeper Why a profitable company can still run out of cash

Profit counts sales when they are made, but cash arrives when customers pay. A fast-growing company can report rising profit while receivables and inventory swallow every unit of cash it earns. If payables fall due before customers pay, the company has to borrow, and if banks and suppliers pull their credit at that moment, it fails despite being profitable. This is why analysts study the cash conversion cycle and the liquidity ratios together with profit.

When a stressed company announces a convertible bond, a rights issue or deferred capital spending, it is drawing on secondary sources. That is a signal worth noticing.

What are drags and pulls on liquidity?

A company’s cash conversion cycle has a large effect on its liquidity position. Two forces work against it.

Drags and pulls on liquidity
Pressure on liquiditytwo ways cash falls short
  • Drag Memorize cash inflows come in slower
    • Uncollected receivables long days sales outstanding (DSO), delinquencies
    • Obsolete inventory unsold or sold at a discount
    • Borrowing constraints tight credit conditions
  • Pull Memorize cash outflows speed up or credit shrinks
    • Paying early with no benefit funds used sooner
    • Reduced supplier credit limits after late payments
    • Limits on credit lines bank cuts
    • Chronically low liquidity often with an aggressive approach

A drag on liquidity is a lag in cash inflows. The longer receipts stay outstanding, the greater the chance they never arrive. Stale inventory ties cash up or can be sold only at a discount, and tight credit makes new short-term debt dearer or unavailable. Stricter credit and collection practices reduce drags, but they may also cut sales.

A pull on liquidity is a speeding-up of cash outflows, or a limit on trade credit that forces the company to pay out before it has received cash from sales. Typical pulls are paying early when there is no financial benefit, suppliers cutting credit limits (often after late payments), banks limiting short-term lines, and chronically low liquidity, which an aggressive working capital approach can make worse.

Some examples show how to classify.

How do the liquidity ratios work?

Ratios compare firms of different sizes. They all divide by current liabilities, and each uses fewer assets on top than the last.

The current ratio is the broadest:

Current ratio Memorize
Current ratio=Current assetsCurrent liabilities\text{Current ratio} = \frac{\text{Current assets}}{\text{Current liabilities}}

A positive total working capital means a current ratio above 1. The quick ratio drops inventory and other less liquid items (such as prepaid expenses):

Quick ratio Memorize
Quick ratio=Cash+Marketable securities+ReceivablesCurrent liabilities\text{Quick ratio} = \frac{\text{Cash} + \text{Marketable securities} + \text{Receivables}}{\text{Current liabilities}}

A quick ratio above 1 means the firm could meet its short-term obligations without selling inventory, provided every receivable is collected on time. The cash ratio is the most conservative:

Cash ratio Memorize
Cash ratio=Cash+Marketable securitiesCurrent liabilities\text{Cash ratio} = \frac{\text{Cash} + \text{Marketable securities}}{\text{Current liabilities}}

Read the ratios together, because actions can move them in different directions. If Halden spends EUR 30 million of cash on extra stock, current assets stay at 210, so the current ratio stays 1.91, but the quick ratio falls to 100 ÷ 110 = 0.91 and the cash ratio to 20 ÷ 110 = 0.18. The firm looks the same on the broadest test and much weaker on the strict ones.

Liquidity ratios are used with the activity ratios from the first lesson. The comparison with peers and over time matters more than a single value, because a normal level differs by industry.

Drag (inflow slows)uncollected receivables, obsolete inventory, tight borrowing conditions
Pull (outflow speeds up)early payments, lower supplier credit limits, bank credit-line cuts, chronically low liquidity

Memory hook A drag holds cash back; a pull drags cash out. Ask whether cash is arriving late (drag) or leaving early or credit is being withdrawn (pull).

Know it cold Issuing equity is a secondary source. Using secondary sources usually signals deteriorating financial health.

How it is asked

  1. Quick ratio from a balance sheet

    Cash 20, securities 10, receivables 75, inventory 80, prepaid 10; current liabilities 150. Quick ratio?

    (20 + 10 + 75) ÷ 150 = 0.70. Traps: 0.20 is the cash ratio; 1.30 is the current ratio.

  2. Drag or pull?

    A supplier cuts the credit limit. Drag or pull?

    Pull. Credit shrinks, so cash must be paid sooner. Obsolete inventory and slow receivables are drags.

  3. Primary or secondary source?

    A share placement, a draw on an existing bank facility, chasing overdue invoices. Which is secondary?

    The share placement is secondary. The bank facility and the collections are primary.

  4. Net proceeds after costs

    Three assets with fair values and liquidation cost percentages. Net cash raised?

    Sum of fair value × (1 − cost %). Trap: reporting gross value or only the costs.

Exam traps

  • Including inventory in the quick ratio. The quick ratio keeps cash, securities and receivables only.
  • Calling a supplier's credit cut a drag. A drag slows inflows; a credit cut is a pull.
  • Treating equity issuance as a primary source. It dilutes owners and signals stress, so it is secondary.
  • Reading ratios in isolation. Building inventory with cash leaves the current ratio unchanged while the quick and cash ratios fall.

Checkpoint

5 exam-style questions. About 90 seconds each.

  1. 1A company has cash of 25, marketable securities of 15, receivables of 60, inventory of 90 and prepaid expenses of 10. Current liabilities total 120. Its quick ratio is closest to:

  2. 2Which development is most likely a drag on liquidity rather than a pull?

  3. 3A company short of cash takes each of the steps below. Which one draws on a secondary source of liquidity?

  4. 4A company in a cash squeeze can sell Treasury bills with a fair value of 20 (no cost), receivables with a fair value of 50 at a 10% cost, and inventory with a fair value of 40 at a 20% cost. The net cash it can raise is closest to:

  5. 5A company received 800 from customers and 5 of interest, and paid 560 to employees and suppliers, 40 in taxes and 25 in interest. It invested 120 in long-term assets. Its free cash flow is closest to:

Key takeaways

  • Primary sources: cash and securities, borrowing, cash flow from operations. Secondary sources are costly crisis measures.
  • Drags slow inflows; pulls speed outflows or cut credit.
  • Current ≥ quick ≥ cash ratio, with the cash ratio the strictest test.
  • Free cash flow = cash flow from operations − investment in long-term assets. Selling assets in a squeeze costs a percentage of fair value.

Questions about this lesson?

Where this comes back

Questions candidates ask

What is the difference between the current, quick and cash ratios?

All three divide by current liabilities. The current ratio uses all current assets. The quick ratio keeps only cash, marketable securities and receivables, leaving out inventory. The cash ratio keeps only cash and marketable securities. So current is at least quick, and quick is at least cash.

What are primary and secondary sources of liquidity?

Primary sources are cash and securities on hand, borrowing (including trade credit) and cash flow from the business. Secondary sources are used under stress and cost more: cutting dividends or capital spending, issuing equity, renegotiating contracts, selling assets and filing for bankruptcy protection.

What is the difference between a drag and a pull on liquidity?

A drag slows cash coming in: uncollected receivables, obsolete inventory, tight borrowing conditions. A pull speeds cash going out or shrinks the credit available: paying early with no benefit, suppliers cutting credit limits, banks cutting credit lines, or chronically low liquidity.
