Under GAAP, there are 2 methods to recognize the income of a long-term construction contract:
(1) Completed-Contract method &
(2) Percentage of Completion Method.
Completed-Contract Method
- Recognize income only on completion of the contract
- Expected loss recognized immediately in the year they are discovered
Calculation:
Gross Profit = Contract Price - (Total Actual Costs)
Gross Profit = contract price - (costs incurred during the year) - (estimated costs to complete)
Percentage of Completion Method
- Income recognized is the percentage of estimated total income
- Loss must be recognized in full immediately in the year discovered
Calculation:
- Gross Profit = Contract Price - (Estimated Total Cost [determined each year])
- % of Completion = (Total Cost to Date)/(Total Estimated Cost of Contract)
- Gross Profit Earned (Profit to Date) = (GP)*(% of Completion)
- Gross Profit Earned for Current Year = PTD at Current Year - (PTD at Beginning of Period)
When to Use Each Method
In order to use the Percentage of Completion Method, all 3 of the following criteria must be met:
- Estimations are reasonable
- Company has the ability to complete the project
- Buyer (other party) is able to pay the contracted payments
GAAP
If there is significant uncertainty exists for any of these, then the Completed Contract Method is required. If the collection of money from the customer in an installement sales contract is significantly uncertain, then the cost recovery method is required.
IFRS
The Completed Contract Method is not allowed under IFRS.
If there is any significant uncertainties in the 3 criteria, then the Cost Recovery Method must be used.
