9. A construction company is negotiating on a construction project with a six-month duration. On the last day of each month the construction company may bill the owner for the work completed during the month. The owner pays the monthly bills 15 days after they are received. The owner also holds 10% retention. Final payment is expect- ed one month after completion of the project and includes payment of the retention. The construction company pays material suppliers in full when it receives payment from the owner.
