debt instrument with discount

It is short term borrowing. Suppose you wanted to borrow $1,000 for a short period. One way is to borrow $1,000 from someone and give them a written promise (the commercial paper) to pay them back $1,020 at the end of a fixed period (say after 30 days). The extra $20 is effectively the same as paying them interest, but instead of actually quoting interest they get a promise to pay them $1,020 but they only had to pay $1,000 for the promise so we say it is being issued at a discount.

Thank you sir

You are welcome :-)
