How should contract modifications/change orders be reflected in revenue and costs when auditing long-term construction contracts?

• A. Ignore in revenue until final settlement; costs recognized when cash is paid.
• B. Treat as separate contracts; revenue and costs not adjusted.
• C. Treat as contract modifications; update the transaction price and estimated costs; recognize revised revenue and costs as performance obligations are satisfied, using revised progress.
• D. Recognize revenue at time of modification and cost when paid.

Answer: (C)

When auditing long-term construction contracts, changes through change orders are integrated into the contract’s accounting rather than ignored or treated as stand-alone events. If the scope or price is modified, you update the contract’s transaction price and the estimated total costs. Then you recognize revenue and costs as the performance obligations are satisfied, using the revised progress toward completion.

In practice, this means recalculating the percentage of completion based on the updated total expected costs, applying that percentage to the revised transaction price to determine cumulative revenue to date, and charging costs incurred to date against the new cost estimate. This preserves accrual accounting by matching revenue with the work actually performed, rather than waiting for final settlement or paying out cash.

This approach is preferred because it accurately reflects the evolving economics of the contract as work progresses. Treating the modification as a separate contract only applies if the modification creates a distinct, standalone obligation; otherwise, integrating it into the existing contract and adjusting revenue and costs up to date is the correct path. Recognizing revenue only at the time of modification or only when cash is paid would misstate performance and timing of earnings.
