Electro Co. recently developed an incentive scheme that allows customers to defer payments to boost sales. On May 1, 2018, a customer signed a purchase agreement with Electro Co. for a television. The television had a list price of $10,000, which represents the price the customer had to pay if full-payment would be made on the purchase date.

The contract permitted the customer to return the television within 3 months, and Electro Co. did not have past experience regarding the return rate of the television.

After the expiration of the return period, the customer paid Electro Co. $5,500 on April 30, 2019 and $5,250 on April 30, 2020. The interest rate charged by Electro Co. is 5% per annum.

The television had a cost of $4,000. Electro Co. has a fiscal year-end of April 30.
