When Does Shipbuilding Backlog Become Revenue? Progress, Contract Prices, and Costs
See what is missed by simply converting shipbuilding backlog into annual revenue. Examine vessel types, contract dates, construction progress, and estimated costs to assess workload and earnings quality.
Shipbuilding backlog shows the scale of contracted work not yet performed, but it is not guaranteed revenue for that year. Conversion into revenue depends on each vessel's construction schedule, progress, and contract terms, while profit depends on the gap between the contract price and actual costs.
Distinguish remaining work from annual production pace
Backlog divided by annual revenue is a rough indicator of how many years of work remain. Because it combines contracts for different vessel types and delivery dates, it does not mean that the same amount will convert into revenue each year. Companies such as HD Hyundai Heavy Industries that provide earnings materials and monthly IR updates allow comparisons of new orders, revenue, and closing backlog. Also distinguish whether backlog growth comes from new contracts, currency translation, or contract modifications. Backlog value, vessel count, and the production burden adjusted for construction complexity convey different information.
Progress is more than elapsed months
IFRS 15 explains that revenue for obligations satisfied over time should be recognized using an appropriate measure of progress. Check the company's notes for the accounting policy applied to individual shipbuilding contracts. If costs incurred are used to measure progress, revisions to estimated total costs, as well as cumulative costs incurred, can change revenue and profit. It is risky to infer strong profitability from backlog alone when steel plate price increases, design changes, subcontracting costs, or production disruptions have raised expected costs. A high vessel price at the time of the order matters only if it can absorb those costs.
Read advance payments alongside contract assets
Shipbuilders may receive part of the payment before construction, while the contractual billing date may not yet have arrived even after work has progressed. Revenue, billing, and cash receipts therefore follow different calendars. Higher advance payments can ease funding needs, but the entire amount is not profit. When contract assets rise, check whether this reflects normal construction, contract modifications, or delayed billing. Cash flow can change sharply when deliveries are concentrated in a period, so do not extrapolate one quarter's cash improvement into long-term profitability. The key is to consider backlog by vessel type alongside changes in cost estimates.
Worked example
Hypothetical example: A vessel has a contract price of KRW 100 billion, estimated total costs of KRW 80 billion, and cumulative costs of KRW 20 billion, and qualifies for the input method. At 25% progress, cumulative revenue is KRW 25 billion and cumulative gross profit is KRW 5 billion. If estimated total costs are revised to KRW 100 billion, the same costs represent 20% progress and cumulative revenue becomes KRW 20 billion. Actual accounting also requires reviewing excluded costs and contract modifications.
What to check
- Have you separated the effects of new orders, exchange rates, and contract modifications on backlog growth?
- Have you checked the construction workload by vessel type and delivery year?
- Have you examined revisions to estimated total costs and provisions?
- Have you distinguished revenue timing from cash receipt schedules?
