Answer:
a. Line of credit - Long-term strategy
A line of credit is a long-term strategy because businesses obtain lines of credit for their use over long periods of time. The particular characteristic is that a line of credit is only used when the business decides to do so, so it works almost like a credit card.
b. Commercial paper - Short-term strategy
Commercial paper is a short-term debt that is issued by firms when they have problems to pay operating expenses. They are unsecured, and pay a specific amount of interest.
c. Trade credit Bank loan of 10 months - Short-term strategy
In financial accounting, loans that last for less than a year are categorized as short-term liabilities, therefore, a trade credit bank loan of 10 months is a short-term strategy.
d. Bond - Long-term strategy
While some bonds are issued for the short-term, the majority of them are issued for the long-term, with some of them lasting 10 years or more.
e. Stock - Long-term strategy
Buying or issuing stock is also a long-term strategy, specially because the dividend of the stock is only paid out once every year, unlike other debt instruments that pay interest immediately.
f. Bank loan of 20 months - Long-term strategy
A bank loan of more than 1 years is considered a long-term liability in financial accounting, therefore, a bank loan of 20 months is part of a long-term strategy.
