Answer:
periodically pay a fixed rate of interest and receive a floating rate of interest.
Explanation:
The interest rate (rate of return) can be defined as the percentage of interest or dividends earned on money that is invested.
In Financial accounting, a return refers to the amount of profit generated by an investor on an investment over a specific period of time.
Basically, the interest rate which is typically expressed as a percentage of the initial costs of an investment can either be a gain or a loss on an investment. Therefore, a positive rate of return on an investment over a specific period of time, simply means that an investor is making a profit (gains) while a negative rate of return on an investment over a specific period of time, indicates that the investor is running at a loss.
By convention, a swap buyer on an interest rate swap agrees to periodically pay a fixed rate of interest and receive a floating rate of interest.
