Answer:
The US GAAP recognizes $20 million.
The IFRS recognizes $40 million.
Step-by-step explanation:
When a liability is uncertain, it is referred to as a contingent liability. Contingent liabilities are only recorded if the company believes that they will actually happen, e.g. warranty liabilities, lawsuits, etc. The US GAAP is rules-based and the IFRS is principles-based, so their approach on recording contingent liabilities varies a lot.
The US GAAP which is the accounting standard used in the US, generally includes in the balance sheet the lowest estimated unfavorable outcome. In this case that would equal $20 million.
The International Financial Reporting Standards (IFRS) which are used in more than 140 countries and even in the US under certain circumstances, states that the midpoint value should be used. In this case that would = ($20 million + $60 million) / 2 = $40 million.
