Seasons Construction is constructing an office building under contract for Cannon Company. The contract calls for progress billings and payments of $1,240,000 each quarter. The total contract price is $14,880,000 and Seasons estimates total costs of $14,200,000. Seasons estimates that the building will take 3 years to complete, and commences construction on January 2, 2014. Seasons Construction completes the remaining 25% of the building construction on December 31, 2016, as scheduled. At that time the total costs of construction are $15,000,000. What is the total amount of Revenue from Long-Term Contracts and Construction Expenses that Seasons will recognize for the year ended December 31, 2016?

Revenue Expenses:

$3,750,000 $ 3,750,000

$14,880,000 $15,000,000

$3,720,000 $ 3,750,000

$3,720,000 $ 4,200,000

I know how to get Revenue: Total contract price multiplied by % construction completed.

I don't understand the calculation to get expenses, I know that it is: 15,000,000 - (14,400,000*.75)= 4,200,000. Where does the 14,400,000 come from?
