What are the main types of unsecured short-term loans?

"Unsecured Short-Term Loans Unsecured loans are made on the basis of the firm’s creditworthiness and the lender’s previous experience with the firm. An unsecured borrower does not have to pledge specific assets as security. The three main types of unsecured short-term loans are trade credit, bank loans, and commercial paper. Trade Credit: Accounts Payable When Goodyear sells tires to General Motors, GM does not have to pay cash on delivery. Instead, Goodyear regularly bills GM for its tire purchases, and GM pays at a later date. This is an example of trade credit : the seller extends credit to the buyer between the time the buyer receives the goods or services and when it pays for them. Trade credit is a major source of short-term business financing. The buyer enters the credit on its books as an account payable . In effect, the credit is a short-term loan from the seller to the buyer of the goods and services. Until GM pays Goodyear, Goodyear has an account receivable from GM, and GM has an account payable to Goodyear. Bank Loans Unsecured bank loans are another source of short-term business financing. Companies often use these loans to finance seasonal (cyclical) businesses. Unsecured bank loans include lines of credit and revolving credit agreements. A line of credit specifies the maximum amount of unsecured short-term borrowing the bank will allow the firm over a given period, typically one year. The firm either pays a fee or keeps a certain percentage of the loan amount (generally 10 to 20 percent) in a checking account at the bank. Another bank loan, the revolving credit agreement , is basically a guaranteed line of credit that carries an extra fee in addition to interest. Revolving credit agreements are often arranged for a period of two to five years. Commercial Paper As noted earlier, commercial paper is an unsecured short-term debt—an IOU—issued by a financially strong corporation. Thus, it is both a short-term investment and a financing option for major corporations. Corporations issue commercial paper in multiples of $100,000 for periods ranging from 3 to 270 days. Many big companies use commercial paper instead of short-term bank loans because the interest rate on commercial paper is usually 1 to 3 percent below bank rates."
