Final answer:
According to IAS 37, Scott should disclose the possible liability as a contingent liability in its financial report.
Step-by-step explanation:
According to IAS 37 Provisions, Contingent Liabilities and Contingent Assets, the most appropriate option for Scott when preparing its financial report for 30 June 20X1 is to disclose information about the possible liability as a contingent liability.
This is because there is a legal dispute with a supplier and the outcome is uncertain.
The disclosure should provide sufficient information about the nature of the dispute, the potential amount involved, and the probability of an unfavorable outcome.
