Answer:
US GAAP requires that contingent liabilities (e.g. lawsuits) must be disclosed in the footnotes of the financial statements of Blythe Corporation. If the contingent liability qualifies as probable and a reasonable cost can be estimated, then it must also be reported as a liability in the balance sheet. But since this lawsuit is only reasonably possible, not probable, then it doesn't need to be included in the balance sheet.
As a general thumb rule, we can assume that probable means that the chance of losing is more than 50%, while possible means that there is a 50/50 chance.
