Letter of credit transactions have been developed since the Middle Ages in connection with the trade of goods at the international level. Individuals and companies have found themselves dealing with partners of whom they know little, located in distant countries with often insecure political and economic situations. Furthermore, the dynamism of the economy creates a need for financing that requires a guarantee of payment at a time and for an amount that must be certain. Diversity in geographical nature, weather, climate, production system, and globalization in culture and fashion has made the countries dependent on each other for the daily necessities. Similarly, one continent is largely dependent on the products of other continents. In addition, diversity in human appetite and attitude, unequal development of technology, desire for luxury, and the development of communication systems and tale-communication revolutionarily increase the necessity of transnational, transcontinental business activities.

As far as the payment issue is concerned, market reality, distance, geographical barriers, uncertainty and lack of confidence among the business actors discourage the global commercial venture. In market reality, the buyer, always, wants to pay the seller only after selling the imported products in the internal market. On the other hand, the seller wants payment as soon as possible ‘if possible, even before shipment’. Moreover, in transnational business transaction, where the goods and the payment are not exchanged simultaneously there is a risk that parties to an exchange may not fulfill their obligations. In such a case the seller may take the payment and not give the good or the buyer take the good and not give the payment. Furthermore, trade transactions between different countries involve different payment systems, conflict of laws, barrier of languages, lack of understanding and reliability among the business partners and other barriers.

Fortunately, letter of credit (LC) or ‘documentary credit’ or ‘banker’s commercial credit’ has Brought a revolutionary solution to all this problems and has ensured sufficient securities and certainty in payment transaction.

As the payment instrument, letter of credit has become widely used in international trade and has been described by English judges as ‘…the life-blood of international commerce…’ Letter of credit takes care of the interests of both the exporter and importer, so it is considered to be the most effective and safest method to secure the payment in an international trade transaction.

The letter of credit as a device plays a dominant role in the execution of a great number of transactions at the international level; the work has been to focus on the bank's position in dealing with documents. Two parties agree on a deal, they know the terms of their agreement and, for different purposes, they decide to involve a third party, a bank, to help them in the execution of the respective obligations.

The principal and most important task of letters of credit transactions is to provide security to the parties with respect to the fulfillment of the reciprocal financial obligations. The involvement of the bank as a credit institution through the issuance of letters of credit offers an opportunity to finance the import and export of goods. The broad credit transaction consists of three separate relationships. The first a relationship between the beneficiary (exporter/ seller) and the issuing bank; the second a relationship between the beneficiary and the applicant (importer/ buyer); and the third is between the buyer and the issuing bank. The first relationship is the Letter of Credit engagement; whereas the second and the third are, respectively called as underlying contract and application agreement or cover relationship.

Under this arrangement the buyer apply for opening a Letter of Credit which is to be issued in favor of the seller. The issuing bank approving the payment obligation opens a Letter of Credit in favor of the seller. This is the basic mechanism of Letter of Credit. However, oftentimes, the seller cannot rely on the buyer’s bank (issuing bank) which is situated in the Buyer’s jurisdiction. In such a case, the issuing bank requests a bank at or near the seller’s business place to advise or notify the credit. The second bank is called advising bank. Here the relationship between the issuing bank and advising bank is that of principal and agent. Alternatively, the seller, who wants commitment of payment by a bank he or she knows, may arrange another bank in his or her jurisdiction.

The confirming bank (seller’s bank) on the assurance of reimbursement by the issuing bank undertakes to pay, accept or negotiate the seller’s draft. The act of confirmation binds the confirming bank to the beneficiary without reducing the liability of the opening bank (issuing bank). That means in case of confirmed letter of credit the seller has rights against both the issuing bank and confirming bank.

There are so many kinds of letter of credit; such as revocable LC, Irrevocable LC, Confirmed LC, and Unconfirmed LC, Red clause LC, back to back LC, Standby LC, Revolved LC and Transferable LC.  Some Letters of Credit are recognized and accepted by Commercial Code of Ethiopia.

1. The Legal principles governing Letter of credits

Letter of Credit transaction based on certain principles which has made it one of the most successful commercial instruments. All type of Letter of credit have legal basis and holds the most important doctrines for using of letter of credit. The two principles are principle of autonomy and strict compliance. 

1.1 Principle of Autonomy

Principle of autonomy is one of the fundamental principles of letter of credit. The essence of this principle is that the Letter of Credit transaction (transaction between seller and the issuing bank) is a separate and independent transaction and it is, no way, connected with any other transactions (for example, second and third transactions, as mentioned earlier in introduction part). As a result of the autonomy principle, the banks do not deal with the goods, services or performance regarding the underlying contract.  

The Principle of autonomy has to be mentioned in our commercial law. Sub-Article (2) of Article 959 of Commercial Code said a documentary credit is independent of any contract of sale on which it may be based and to which a bank is not a party {Emphasized Added}. The payment obligation of issuing bank to beneficiary (exporter) is separated from the performance of beneficiary based on the sales contract. As long as beneficiary presents the compliant bill of documents, issuing bank should accept even though beneficiary disobeyed the sales contract that made with the applicant (importer).

The payment obligation of issuing bank is also independent of the underlying the contract between applicant and bank. For example, applicant goes bankruptcy after the bank issues letter of credit. Although applicant cannot pay the money, issuing bank still cannot reject the payment obligation. In general, breach of underlying contract by the seller does not immune the bank from its payment undertaking. At the same way, the bank is not allowed to refuse the payment ‘just because of the buyer’s failure to put it in funds.  

Although the principle of autonomy is set up steadily, it is not absolutely. There are some exceptions in the real practice. Fraud is the main exception for principle of autonomy. The ‘fraud exception’ means that banks obey the principle of autonomy in general situation; however, if banks keep the obvious evidence of the fraud behavior of beneficiary, banks could refuse to pay. Applicant can require the bank for rejection, or apply the payment injunctive from the court.

1.2 The principle of Strict Compliance

The presented documents must be in accordance with the terms and conditions of the letter of credit. Based on the contract between applicant (importer) and issuing bank, the bank has the obligation to observe the borders of the commission given to it and fulfils the request by observing the principle of strict compliance. Issuing bank keeps the rejection right when it meets the documents that disobey this principle.

This Principle is incorporated in our legal system; Article 965 and 966 of the Commercial Code said that the bank shall satisfy itself that the documents conform strictly to the Instructions contained in the credit. When it refuses documents the bank shall notify the presenter within as short a time as possible and inform him of the errors found. The bank shall not incur any liability where the documents are on their Face in conformity with the instructions received. It shall not incur any obligation in relation to the goods which are the subject of the credit Opened {Emphasized Added}. Under the term of letter of credit, issuing bank perform the payment obligation no other than the exporter submits the documents which is strict compliance with the clauses of letter of credit on the appearance. Thereby strict compliance becomes the fundamental principle, which restricts the right and obligation between issuing bank and exporter. The investigation in recent years indicates that: 

About 50% rejection of payment is resulted from the discrepancies between the documents and credit, which decrease the effectiveness of letter of credit, and cause the financial effects for the parties. Banks must examine all documents stipulated in the credit with reasonable care, to ascertain whether or not they appear, on their face, to be in compliance with the terms and conditions of the credit.

2. Types of Letter of Credit 

Although they utilize the same basic mechanism as the standard letter of credit, the specialized types have been designed to satisfy specific needs in the business world. Depending on the degree of trust and confidence, the parties dispose of two different forms of commercial letters of credit, such as ‘revocable’ and ‘irrevocable’.

2.1 Irrevocable and revocable letters of credit

Revocable Letter of Credit does not provide the beneficiary with any particular form of security; the revocable letter of credit can be canceled or amended at any time prior to payment, at will and without warning or notification. This form does not give any security to the beneficiary and all the advantages are to the benefit of the buyer, who disposes with absolute flexibility. Therefore, the beneficiary will accept a revocable letter of credit not only when he has absolute trust in the buyer, but also when he trusts the issuing bank. Article 962 and 961 of the Commercial Code recognizes Revocable Credits, which credits do not constitute a binding agreement between the opening bank and the beneficiary. Hence, it may be modified or cancelled by the opening bank at any time by a notice communicated to the correspondent bank prior to payment or negotiation, or the acceptance bills there under by the latter. A documentary credit is presumed to be revocable in the absence of a provision that clearly specifies that it is irrevocable.

Whereas Irrevocable Letter of Credit may involve the undertaking of a second bank, in addition to the issuer, and which represents the most secure among the letter of credit types. Under an irrevocable letter of credit, the issuing bank commits itself irrevocably to honor its obligation under the letter of credit upon full compliance by the beneficiary with all the credit conditions. Irrevocable credits are credits which represent a definite undertaking between the opening bank and the seller/beneficiary or good faith holders of bills of exchange, drawn by the beneficiary. Hence, the bank is obliged to pay the money specified in the credit (Commercial Code Article 963). Such undertakings can neither be modified nor cancelled without the agreement of all persons concerned (Commercial code Article 964/3/). There is no difference in ̔̔̔̔the rapidity and convenience of payment ̕ under the revocable or the irrevocable letter of credit: both devices require the documents to be delivered under the same conditions and examined by the bank with the same level of scrutiny. There are two forms of irrevocable letters of credit, such as unconfirmed and confirmed LC.

2.2 Confirmed and unconfirmed letters of credit

Unconfirmed Letter of Credit offers a commitment to pay only on the part of the issuing bank. When the irrevocable letter of credit involves a third bank, the advising bank, it is only to act on behalf of the issuing bank for administrative purposes, such as the notification of the letter of credit to the beneficiary, the collection and transfer of the documents, and the payment of the money to the beneficiary when received from the issuing bank.

Whereas Confirmed Letter of Credit represents the most secure device because it offers an unconditional undertaking by two entities; the issuing and the confirming bank in confirming the credit, the advising bank enters into a commitment to pay that is independent of, in addition to, the issuing bank's commitment. The confirming bank undertakes to honor its commitment regardless of whether the issuing bank is in a position to reimburse it, thus granting the beneficiary an additional guaranty of payment. Sub-Article (1) of Article 964 The Commercial code said that This type of letter of credit may also be confirmed by the correspondent bank upon the request of the opening bank, and where irrevocable letters are confirmed by the correspondent bank / confirming bank/, a binding relation will be created between the beneficiary of the credit and the correspondent bank and the latter will be liable on the letter of credit. We can see an increased rapidity of payment comparing both of them to the confirmed letter of credit because the latter requires transfer of the documents and wire of the money through an additional entity, the confirming bank.

2.3 The Standby Letter of Credit

The standby letter of credit which has been developed specifically to overcome the legal obstacle of the prohibition for banks to issue guaranties, the specialized types of letter of credit is designed to provide efficiency to certain transactions. Payment is not automatic but is conditional to an event which is uncertain. the bank may never be called to execute the payment. The standby credit is often used in sales transactions to provide the buyer with a guarantee of performance by the seller, thus providing the same service as the performance bond.

In the U.S., where the performance bond is a contract dependent on the underlying transaction, the standby letter of credit has the advantage that the bank is not concerned with the determination of the obligor's default. This allows the beneficiary to receive payment upon presentation of a simple declaration of default and without having to go through judicial establishment of the right to be indemnified (note that the mechanism of the standby letter of credit is the same as the one of the performance bond as it is known in Germany or in Switzerland). The development of the surety business by U.S. banks has created a similar structure, though under a different name. Thus, the standby letter of credit serves many purposes: to provide liquidity, to substitute traditional credit forms, to reduce credit costs, to shift litigation costs, and to cause prompt payment. A description of the different options offered by the standby credit and for an illustration of the variety applications. With the standby letter of credit, the bank provides a guaranty without incurring the risk of having to pay without being indemnified, as may happen to the traditional surety company. If the customer becomes insolvent the bank may be compensated from the security or from the customer's account. The standby letter of credit becomes, in practice, a form of secured loan to the benefit of the customer.

2.4 The Revolving Letter of Credit

The Revolving Letter of Credit which allows the rationalization of medium to long term deals, involving individual payments for multiple shipments. This form of letter of credit is adopted in cases of transactions involving shipment of goods on a continuing basis and payment of the total price in multiple installments of similar amounts. The revolving credit is not designed to cover the full value of goods agreed upon, but the value of the individual shipments to be executed at different times. Technically the beneficiary receives a letter of credit for the amount of the highest installment. At the execution of each shipment he may draw the corresponding amount without causing expiration of the letter of credit. The credit may revolve in relation to time, i.e. up to a certain amount for a specified number of times during a certain period, or in relation to value, i.e. for a certain amount to be reinstated each time for a certain period.

2.5 The red clause Letter of Credit

The red clause Letter of Credit, whose name is derived from originally being written in red ink, the beneficiary is provided with the right to draw certain amounts of money prior to the execution of his obligation. It is a form of financing representing a non collateralized loan to the beneficiary. Usually it is applied to the benefit of brokers or dealers, who often do not dispose of the amounts necessary to finance the deal. The red clause credit is also used by manufacturers who need to dispose of funds prior to the shipping of the goods in order to start production. In consideration of the high risk involved in this type of credit, it is important that the buyer has extreme trust in the beneficiary and in his capability to perform the obligations of the underlying contract. There are different methods that the buyer may use to avoid abuses from the side of the beneficiary; the most secure is the issuance of a letter of indemnity, but the beneficiary who requests a red clause credit is probably not in the condition to guarantee a bank for the issuance of such a device. A second possibility is to request the delivery of documents certifying that the money drawn is used for the purposes for which the red clause credit has been granted.

2.6 The Back-to-back Letter Of Credit

The Back-to-back Letter Of Credit which is used as a basis for the issuance of a second, unrelated, letter of credit. The back-to-back credit allows the beneficiary to use the letter of credit as a financing device. In short, the beneficiary who needs to provide guarantees to a third party may pledge the letter of credit to a bank as collateral for the issuance of a second letter of credit. In this case, it is the bank, and not the customer, as in the case of the red clause credit, that trusts the beneficiary of the first letter of credit and believes that he will comply with the obligations of the first letter of credit. It could happen that the bank is called on to pay the beneficiary of the second letter of credit, but is not able to recover the amount of the first credit because its customer did not comply with his obligations. For this reason, banks do not care for this form of credit, and as a matter of practice tend to refuse to issue second credits.

2.7 The Transferable Letter Of Credit

To be transferable, the Letter of Credit must be so marked by the issuing bank on the instructions of the buyer or importer (the account-party). On the instructions of the first beneficiary the advising bank can transfer it to the second beneficiary but not any further. A Transferable Letter of Credit is used in cases where there are three parties to a transaction; an Importer (Buyer), Exporter (Supplier), and an intermediary party, such as a broker, who is responsible for arranging the sale. In such a transaction, the intermediary party requests a Letter of Credit from the Importer as protection against non-payment. The Exporter, in turn, wants assurance from the intermediary party that payment will be made, and will also request a Letter of Credit.

It may be the case that the intermediary party has little working capital or does not have access to a line of credit with its bank to issue a separate Letter of Credit to the Exporter. As an alternative, the intermediary party may provide such assurance to the Exporter by transferring over a portion of the Letter of Credit it received from the Importer. The Commercial Code of Ethiopia recognizes and includes Transferable Letter of Credit; Article 967 of commercial Code says that A documentary Credit is only transferable or divisible where a bank is authorized to pay in whole or in part to one or more third parties on the Instructions of the first beneficiary. A credit is only transferable on the Express order of the bank opening the credit. It is so transferable once only, unless otherwise provided. 

This also provides the beneficiary with an indirect financing opportunity. This form of letter of credit allows the beneficiary to transfer all or part of his rights to a third party. It is a financing device particularly useful to middle persons who need to pay their supplier for the goods which are sold to the buyer in the underlying contract.
