----- Nội dung ảnh ----- For example, Crandall Co. has a contract to sell 100 products to a customer for $10,000 ($100 per product) at various points in time over a six-month period. After 60 products have been delivered, Crandall modifies the contract by promising to deliver 20 more products for an additional $1,900, or $95 per product (which is the standalone selling price of the products at the time of the contract modification). Crandall regularly sells the products separately.
