Commercial Paper (CP) is a short-term unsecured promissory note issued by corporations to raise funds for meeting short-term liabilities like payroll, accounts payable, and inventory. It was introduced in India in 1990 to provide highly-rated corporations an alternative to bank loans at lower interest rates. Only reputable companies with high credit ratings can issue CPs that mature between 15 days and one year, allowing them to borrow at lower rates than banks to fulfill working capital needs.
