Short-term funding for companies: credit lines, secured loans and commercial paper

Companies borrow short term from banks (uncommitted lines, committed lines, revolvers), against assets (secured loans, receivables) or from investors (commercial paper). The more reliable the promise to lend, the more it costs in fees and covenants. Weaker borrowers must pledge assets.

What are the bank lines of credit?

A company that needs cash for a few weeks or months, for example to bridge the gap between paying suppliers and collecting from customers, usually starts with its bank. It has three choices, ranked by how sure the company can be that the cash will be there. Banks charge a market reference rate (MRR) plus a borrower-specific spread, only on the amount drawn.

    • US commercial paper Know the idea large, liquid market
    • Eurocommercial paper Know the idea smaller deals, less liquid

An uncommitted line of credit is the least reliable. The bank agrees to lend up to a set amount for a set maximum period, but keeps the right to refuse any request. The company pays interest only on what it borrows, with no other fee, so under normal conditions it is the cheapest and most flexible source. Banks offer these unsecured lines to clients who keep stable cash deposits with them, because falling balances warn the bank early that something is wrong. The catch: the bank is most likely to say no exactly when the company is in trouble and alternative funding is expensive.

A committed (regular) line of credit is a formal written commitment, so it is more reliable. It is usually unsecured and can be repaid without penalty. Commitments of under a year (usually 364 days) keep the bank’s capital charge low, so these lines must be renewed, and renewal is the weak point for a borrower whose credit is slipping. The company pays a commitment fee on the unused amount (sometimes on the full line) for the commitment period. For larger borrowers a group of banks often shares the line in a syndicate. Once drawn, the line is a short-term liability (usually notes payable). Uncommitted lines and revolvers are more common in the United States; committed lines are more common elsewhere.

A revolving credit agreement (revolver) is the most reliable source of short-term bank funding. It is a multiyear commitment, with pricing and commitment fee like a committed line, but lenders also ask for covenants that require or restrict borrower actions, as in a bond indenture.

How do you cost a committed line?

The all-in cost has two pieces: interest on the amount drawn, and the commitment fee on the amount left unused. The fee is owed even if nothing is drawn, which is why the all-in rate on the money actually used is higher than the quoted interest rate.

Annual cost of a committed line Use it
Cost=D×(MRR+s)+(L−D)×f\text{Cost} = D \times (\text{MRR} + s) + (L - D) \times f

Here LL is the size of the line, DD the amount drawn, ss the bank’s spread and ff the fee rate on the unused part.

Rearrange itCommitted line: solve for total cost, all-in rate or fee
The question asks for
A company has a 50 million committed line with a commitment fee of 0.30% on the unused amount. It draws 20 million for a full year at 5.25%. Its total annual cost, in millions, is closest to:

20 × 5.25% + 30 × 0.30% = 1.14 million

Total annual cost (millions)1.14

All-in cost on the money used Use it
rall-in=CostDr_{\text{all-in}} = \frac{\text{Cost}}{D}

Read the question for the fee base. “On the unused amount” means L−DL - D; some lines charge the fee on the full line instead, which gives a bigger fee. The fee on the full line would be 50m × 0.30% = USD 150,000 in the example above.

What if the company cannot borrow unsecured?

Use it

Companies without enough credit quality for unsecured loans arrange a secured loan , also called an asset-based loan. The lender takes collateral, such as fixed assets, high-quality receivables, inventory or marketable securities, and files a security interest (a lien) against it. The lien appears on the borrower’s credit record.

Receivables get two special treatments, and the exam tests the difference:

  • In an assignment of accounts receivable , the receivables are collateral for a loan. The company stays responsible for collecting them.
  • In factoring , the company sells its receivables to a lender, the factor, usually at a discount. The factor takes over credit-granting and collection. The size of the discount reflects the credit quality of the accounts and the cost of collecting them.

What is commercial paper?

A commercial paper (CP) note is a short-term unsecured note sold by a large, highly rated issuer, in the public market or by private placement. It usually matures in under three months. Companies use it for working capital, seasonal cash needs and bridge financing (interim funding until permanent financing is arranged). For the strongest issuers it can be cheaper than a bank loan, which is why they use it. Financial institutions, governments and supranational agencies are also large issuers.

Maturing paper is normally repaid with the proceeds of new paper. If the market will not buy the new paper, the issuer cannot repay. That is rollover risk . Investors therefore usually require a backup line of credit from banks (also called a liquidity enhancement), which ensures the maturing paper can be repaid in full if a rollover is not possible. A credit rating does not remove rollover risk, and bridge financing needs more issuance, so it adds to it.

Paper issued in the international market is Eurocommercial paper (ECP). It is similar to US paper, but typical deals are much smaller and the market is less liquid.

Go deeper Why banks offer uncommitted lines at all

Uncommitted lines need almost no regulatory capital until they are drawn. They keep the relationship alive, and the borrower’s deposit balances let the bank monitor its health. Often the funding comes from stable deposits that customers rarely touch. That mix of low cost to the bank and low cost to the client is why they are common, especially in the United States.

Go deeper Why committed lines are often 364 days

A commitment shorter than a year attracts a lower capital requirement for the bank. The price of that saving is renewal risk: when the line comes up for renewal, a heavily drawn borrower whose credit has weakened may find the bank unwilling to extend it. Revolvers solve this with a multiyear term, at the price of covenants.

Go deeper Inventory as collateral

Inventory can back a loan in several ways, with the lender holding a lien over the stock. The curriculum mentions the idea only briefly. Know that inventory is one of the assets that can be pledged, alongside receivables and fixed assets.

Memory hook You pay for certainty: more promise, more fee. Reliability and cost rise together, left to right.

Know it cold Interest is on the amount drawn only. The commitment fee is on the unused amount (sometimes the full line) and is paid even if nothing is drawn.

MemorizeCommercial paper and receivables

Memory hook Paper rolls, so it needs a net: rollover risk is covered by a backup line, not by a rating.

Know it cold CP: unsecured, large highly rated issuers, usually under 3 months. Factoring sells receivables (factor collects). Assignment pledges them (company collects).

How it is asked

  1. Most reliable bank funding

    Which short-term bank funding is most reliable for a company?

    Revolver (multiyear, covenants). Trap: committed line (reliable but shorter, renewable).

  2. No fee, flexible

    A strong client with stable deposits wants a line with no commitment fee.

    Uncommitted line. Trap: committed line (carries a fee).

  3. Line cost, two steps

    Line size, amount drawn, MRR + spread, fee on the unused amount. Total annual cost?

    Interest on drawn, fee on unused, add. Traps: no fee; fee on the whole line.

  4. Rollover risk of paper

    What do investors require to manage the risk that the issuer cannot sell new paper?

    Committed backup line of credit. Traps: uncommitted line (bank can refuse); credit rating.

Exam traps

  • Calling the uncommitted line the most reliable because it is the cheapest. It is the cheapest and the least reliable.
  • Mixing up factoring (receivables sold, factor collects) and assignment (receivables pledged, company collects).
  • Saying a credit rating reduces commercial paper rollover risk. The backup line of credit does.
  • Charging the commitment fee on the whole line when the question says unused amount, or leaving the fee out.

Checkpoint

4 exam-style questions. About 90 seconds each.

  1. 1A company wants a bank to commit funding that cannot be withdrawn for the next three years, and it accepts covenants like those in a bond indenture in return. It is most likely arranging a(n):

  2. 2A company has a CHF 40 million committed line with a 0.25% annual fee on the unused amount. It draws CHF 15 million for a full year at MRR 3.10% plus 140 bps. Its total annual cost is closest to:

  3. 3Investors in a company's 60-day commercial paper worry that the company may not be able to sell new paper when the current paper matures. The protection they most likely require is:

  4. 4A company sells USD 3.2 million of accounts receivable to a factor at a 4% discount. The cash the company receives now is closest to:

Key takeaways

  • Reliability: uncommitted < committed < revolver. Commitment fees and covenants rise with it.
  • Weaker borrowers pledge assets. Factoring sells receivables. Assignment pledges them.
  • Commercial paper is cheap for strong issuers but carries rollover risk, covered by a backup line of credit.
  • Line cost = interest on the drawn amount + fee on the unused amount.

Where this comes back

Questions candidates ask

What is the difference between a committed and an uncommitted line of credit?

A committed line is a formal written promise to lend, usually for 364 days, paid for with a commitment fee. An uncommitted line costs only interest on what is drawn, but the bank can refuse to lend.

What is rollover risk in commercial paper?

The risk that the issuer cannot sell new paper to repay paper that is maturing. A committed backup line of credit is how investors protect against it.

What is the difference between factoring and assigning receivables?

Under factoring the company sells its receivables to a factor at a discount, and the factor takes over credit and collection. Under assignment the receivables are only collateral for a loan, and the company still collects.
