## When Outcome Cannot Be Estimated Reliably
### When Does This Situation Arise?
In the early stages of a contract, when the contractor cannot reliably estimate:
- Total contract costs
- Stage of completion
- Whether the contract can be fulfilled
### The Rule
- Revenue recognised = Contract costs incurred (only to the extent recovery is probable)
- No profit is recognised
- Contract costs are expensed as incurred
Result: Zero profit for the period (break-even recognition).
### Why This Approach?
Since the contractor cannot estimate if the contract is profitable, it is too aggressive to recognise any profit. Revenue = Cost preserves conservatism while still reflecting that work is being done.
### P&L Format
```
Dr. Contract Cost xxx
Cr. Contract Revenue xxx ← same amount as costs incurred
```
### Important: Loss Still Recognised Immediately
Even when outcome is unreliable, if an expected loss exists it must still be recognised immediately (prudence still applies).
### When Does This End?
Once the outcome can be reliably estimated → switch to the Percentage Completion Method prospectively (treated as change in accounting estimate).
