The use of the term 'could' doesn't really sat anything. The term 'could' explains nothing about probability or likelihood.
Assume for a moment it is likely, will it be of consequence to the SP? A serious class action might, but as seen in James Hardie and tobacco cases, unlikely for a company the size of TSE. Much depends on capital structure and revenues at the time. Hopefully, TSE has an indemnity clause of sorts in the contract.
