Hi Amrdowidar. I am taking Intermediate Accounting 2, and the book says "Accounting for contingent losses is quite similar between IFRS and U.S. GAAP. A loss contingency is accrued under U.S. GAAP if it’s both probable and can be reasonably estimated. IFRS is similar, but defines “probable” as “more likely than not,” which is a lower threshold than typically associated with “probable” in U.S. GAAP. Also, IFRS refers to these accrued liabilities as “provisions,” and refers to possible obligations that are not accrued as “contingent liabilities,” while the term “contingent liabilities” is used for all of these obligations in U.S. GAAP.
If there is a range of equally likely outcomes associated with a contingency, IFRS requires using the midpoint of the range, while U.S. GAAP requires use of the low end of the range.
Another difference in accounting relates to whether to report a long‐term contingency at its expected future value or its present value. IFRS requires reporting, present values of estimated cash flows when the effect of time value of money is material. U.S. GAAP allows using present values under some circumstances when the timing of cash flows is fixed or reliably determinable.
." I hope it will help you to understand the difference.
