What is the 'constraint' on variable consideration and how do I apply it?

After estimating variable consideration, ASC 606 requires you to include only amounts for which it is 'probable' (IFRS: 'highly probable') that a significant reversal will not occur when the uncertainty is resolved. This is the constraint — a ceiling on recognition. Factors that increase the risk of reversal include: (1) susceptibility to factors outside the entity's control, (2) long uncertainty resolution period, (3) limited experience with similar contracts, (4) broad range of possible outcomes, (5) practice of offering price concessions. Example: Halimede Biotech has a milestone contract where it receives $12M upon FDA approval, estimated at 60% probability. Expected value = $7.2M. However, FDA outcomes are highly uncertain and outside Halimede's control — the constraint likely caps recognizable variable consideration at $0 until approval is received. Contrast with Tidewell Agriculture's historical rebate program, where 15 years of data show rebates averaging 4.2% with a tight standard deviation of 0.3%. Here the constraint may allow full expected-value recognition because reversal is unlikely to be significant. Revenue timing is reassessed each period; the constraint is not a one-time test. ```mermaid flowchart LR A[Estimate] --> B[Constraint Test] B --> C{Reversal
