Letter of Credit Discrepancy: a Worked Example

The leather was right. The paper was not.

BY MICHAEL SHANG · SIXTEEN YEARS IN COMMERCIAL BANKING · UPDATED · 6 MIN READ

// THE SHORT ANSWER

A discrepancy is a fault in the paper an exporter presents under a letter of credit, and it suspends the bank's obligation to pay until it is cured or the buyer and the bank agree to overlook it. The ICC estimates that 65% to 80% of documents worldwide are refused on first presentation. A refusal need not end in non-payment, but at the least it brings delay and fees, and for that time the exporter is relying on the buyer it asked for a credit to avoid. That is why a lender reads an exporter's presentation record beside its debtor ledger: it shows whether the bank's promise can be collected.

// 01 — WHY A SMALL ERROR SUSPENDS A BANK'S PROMISE

A letter of credit is separate from the sale behind it. The bank has not promised that the goods are good; it has promised to pay against documents that comply. Most credits incorporate the ICC's rules, UCP 600, which apply because the credit says so and are not legislation in New Zealand, Australia or the UK. The examiner decides on the documents alone and on their face.

The standard is commonly called strict compliance, although UCP 600 itself does not use the phrase, and an ICC Banking Commission paper accepts that a defined meaning cannot be read out of the rules. Under the rules, data in a document need not be identical to the credit or to other documents, but must not conflict. ICC practice guidance treats a typing error that does not change the meaning as harmless, and a wrong model number as a discrepancy. English law states the test firmly. The House of Lords said in 1927 that documents which are almost the same will not do, and English courts have not adopted a looser rule of substantial compliance, though obvious typing errors have been treated as falling outside it. A careful reader treats the requirement as exacting while knowing it is not a demand for mirror images.

// 02 — HOW A REFUSAL RUNS

Examination up to 5 banking days following presentation
Notice one notice, listing every discrepancy, by close of day 5
Waiver the issuing bank may ask the applicant; it need not accept
Too late a bank that misses this loses the right to claim non-compliance

The ICC groups common faults as timing (expiry, latest shipment, the presentation period) and poor preparation: conflicting data, missing documents, unauthenticated alterations, missing endorsements, a goods description that does not follow the credit, wrong ports, an insurance document dated after shipment. Where a credit requires a transport document and states no period, UCP 600 sets 21 calendar days after shipment, and in every case not later than expiry.

There are four ways out. The exporter can correct and re-present, if the credit and the presentation period are still open. The buyer can waive. The credit can be amended, which needs the issuing bank, any confirming bank and the exporter to agree. Or the documents can be sent on for collection or approval, which leaves the bank's promise out of it altogether.

// 03 — THE EXAMPLE

A tannery, constructed for this page like every figure in it, sells finished hides for US$640,000 under a sight credit requiring presentation within 14 days of shipment and expiring on 30 April. It ships on 9 April, so its last day is 23 April. Its bank has advanced 85% of the invoice at 8%, on the strength of the credit. The tannery presents on 21 April. Four banking days later, on 27 April, a notice of refusal arrives listing two faults: the invoice says finished bovine leather where the credit says full-grain bovine leather, and the insurance certificate is dated 10 April, a day after shipment, with nothing on it to show cover began by 9 April.

Both documents could be fixed in an afternoon. It does not help. The presentation window closed on 23 April, so a corrected set would now be late, which is a further discrepancy. Everything rests on the buyer, leather prices have softened, and the buyer offers to waive in return for 4% off. Payment arrives on 23 May, 26 days later than planned.

Invoice under the credit 640,000
Price reduction for the waiver, 4% (25,600)
Discrepancy fee, as the credit allowed (150)
Received 614,250
Advance: 640,000 × 85% 544,000
Extra interest: 544,000 × 8% × 26 ÷ 365 3,100
Total cost: 25,600 + 150 + 3,100 28,850
As a share of the invoice: 28,850 ÷ 640,000 4.5%
Gross margin at 12%: 640,000 × 12% 76,800
Share of that margin lost: 28,850 ÷ 76,800 38%

The price reduction and the margin are the example's. A buyer may waive for nothing, or decline. The point is the sequence. For those 26 days the bank's advance had no issuing bank behind it, only the buyer's goodwill and the tannery's own balance sheet.

// 04 — HOW IT DIFFERS FROM A DISPUTE ABOUT THE GOODS

A discrepancy concerns paper. Short of fraud, a buyer who is unhappy with the hides has no ground to stop a complying presentation, and an issuing bank has no ground to refuse because the goods were poor. The reverse is the trap: goods can be perfect and the documents can still fail.

A waiver also differs from an amendment. An amendment changes the terms, generally before the presentation, and the bank's undertaking continues on the new terms. A waiver accepts a fault after the event and is the applicant's to give; the issuing bank then decides whether to accept it. A confirmed credit offers no shelter here, because a confirming bank's undertaking also depends on a complying presentation.

// 05 — WHERE IT DECIDES A FILE

A lender financing against letters of credit is lending on an undertaking that exists only if the back office performs. It therefore asks for the presentation history: how many sets went in, how many came back, what the faults were and how long they took to clear. A small exporter with a clean record and a large one with repeated timing faults are different risks on the same product.

A record of repeated waivers needs reading carefully. If the buyer overlooks a fault every time, the sale has been working like a collection with a letter of credit's cost, and the exporter's payment has rested on the buyer's willingness all along. Many banks offer to check documents before they go, which moves the discovery of the fault to a date when it can still be corrected. The ICC puts much of the problem upstream too, in credits badly drafted and documents badly prepared, so an exporter that reviews each credit on receipt, and asks for changes before shipping, takes out a good part of the risk before anyone has to examine anything.

// QUESTIONS PEOPLE ASK

What happens if the buyer refuses to waive a discrepancy?
The issuing bank does not pay, and the documents are held or returned as its notice said. The exporter keeps control of the goods while a full set of negotiable bills of lading stays with the banks or comes back to it, but the cargo may be sitting at a foreign port, and it must find another buyer, ship them home or negotiate. If the fault can still be corrected within the credit's time limits, it can present again. The bank's promise is revived only by a complying presentation or an accepted waiver.
Is a typing error a discrepancy under a letter of credit?
Not necessarily. ICC practice guidance treats a slip of spelling or typing as harmless where the meaning survives it, and an error that changes the meaning, such as a wrong model number, as a discrepancy. Examiners differ at the margin and a refused exporter has to argue the point while unpaid, so the practical approach is to correct such errors before presenting.
How long does a bank have to reject documents?
UCP 600 gives each bank up to five banking days after the presentation to examine the documents, and any refusal notice must go out by the close of the fifth. It must state every discrepancy and what the bank is doing with the documents. A bank that fails to do this cannot then claim the documents did not comply. Asking the applicant for a waiver does not extend the period.
Who pays the discrepancy fee?
It is usually deducted from the exporter's proceeds, because the exporter is the party whose presentation caused the extra work. Amounts vary by bank. The ICC's Banking Commission has said that an issuing bank intending to deduct a discrepancy fee should state this in the credit, together with an indication of the fee, and notes that neither it nor UCP 600 can set how the market handles the charge.
