Incentive payment 15. On July 1, 20x1, Zevrek Co. enters into contact with a customer for the construction of a building. The contract price is P6M. However, Zevrek Co. is entitled to a bonus of P500,000 if the building is completed within 3 years. Zevrek Co. uses the 'cost-to-cost' method in measuring its progress on the contract. At contract inception, Zevrek Co. estimates total contract costs of P4M. In 20x1, Zevrek Co. incurs total costs of P1,350,000. Due to bad weather conditions, Zevrek Co. does not expect that it can finish the building on time for it to be entitled to the bonus. The estimated costs to complete as of the end of 20x1 are P2.4M. In 20x2, Zevrek Co. incurs total costs of P2,260,000. Due to improvements in weather conditions, Zevrek Co. now believes that it is highly probable that the building will be finished on time and the bonus will be received. The estimated costs to complete as of the end of 20x2 are P190,000. Requirement: Compute for the revenues, costs of construction and gross profits in 20x1 and 20x2, respectively
