Debt is money owed by one party, the borrower or debtor, to a second party, the lender or creditor. The borrower may be a sovereign state or country, local government, company, or an individual. The lender may be a bank, credit card company, payday loan provider, or an individual. Debt is generally subject to contractual terms regarding the amount and timing of repayments of principal and interest. A simple way to understand interest is to see it as the “rent” a person owes on money that they have borrowed, to the bank from which they borrowed the money. Loans, bonds, notes, and mortgages are all types of debt. The term can also be used metaphorically to cover moralobligations and other interactions not based on economic value. For example, in Western cultures, a person who has been helped by a second person is sometimes said to owe a “debt of gratitude” to the second person.

A company may use various kinds of debt to finance its operations as a part of its overall corporate finance strategy. A term loan is the simplest form of corporate debt. It consists of an agreement to lend a fixed amount of money, called the principal sum or principal, for a fixed period of time, with this amount to be repaid by a certain date. In commercial loans interest, calculated as a percentage of the principal sum per year, will also have to be paid by that date, or may be paid periodically in the interval, such as annually or monthly. Such loans are also colloquially called “bullet loans”, particularly if there is only a single payment at the end – the “bullet” – without a “stream” of interest payments during the life of the loan. A syndicated loan is a loan that is granted to companies that wish to borrow more money than any single lender is prepared to risk in a single loan. A syndicated loan is provided by a group of lenders and is structured, arranged, and administered by one or several commercial banks or investment banks known as arrangers. Loan syndication is a risk management tool that allows the lead banksunderwriting the debt to reduce their risk and free up lending capacity. A company may also issue bonds, which are debt securities. Bonds have a fixed lifetime, usually a number of years; with long-term bonds, lasting over 30 years, being less common. At the end of the bond’s life the money should be repaid in full. Interest may be added to the end payment, or can be paid in regular installments during the life of the bond.

A letter of credit or LC can also be the source of payment for a transaction, meaning that redeeming the letter of credit will pay an exporter. Letters of credit are used primarily in international trade transactions of significant value, for deals between a supplier in one country and a customer in another. They are also used in the land development process to ensure that approved public facilities will be built. The parties to a letter of credit are usually a beneficiary who is to receive the money, the issuing bank of whom the applicant is a client, and the advising bank of whom the beneficiary is a client. Almost all letters of credit are irrevocable, i.e., cannot be amended or canceled without prior agreement of the beneficiary, the issuing bank and the confirming bank, if any. In executing a transaction, letters of credit incorporate functions common togiros and traveler’s cheque. Typically, the documents a beneficiary has to present in order to receive payment include a commercial invoice, bill of lading, and a document proving the shipment was insured against loss or damage in transit. However, the list and form of documents is open to imagination and negotiation and might contain requirements to present documents issued by a neutral third party evidencing the quality of the goods shipped, or their place of origin. Companies also use debt in many ways to leverage the investment made in their assets, “leveraging” the return on their equity. This leverage, the proportion of debt to equity, is considered important in determining the riskiness of an investment; the more debt per equity, the riskier.
