A large company has just issued a 60-day commercial paper with a face value of $500,000. The company received initial proceeds of $490,000 from selling the commercial paper (sold at a discount).

The interest amount paid by the issuer at maturity. 3. The effective 60-day rate. 4. The effective annual rate (assuming the commercial paper is rolled over every 60 days for a year)
