I wouldn't go too crazy over IFRS, but of course you need to know it. You can be sure, the less you study it, the more it will appear on your test. Still, for example, the Becker textbooks can go in to a LOT of detail– I would say even too much detail. To be perfectly honest with you I did not even read these parts of the Becker book. With that said, I would definitely memorize the points Jeff mentions in the NINJA AUDIO if you have that…
Those include, but are not limited to,
Knowing the IFRS terms for b/s, i/s, r/e, cash flows.
Knowing that IFRS is principles-based (GAAP is rules-based)
Just memorize the key GAAP and IFRS methods and the differences between them. I do not think you will need to do to much more than that. Do not wrack your brain over ever single difference. Examples of important differences:
Under IFRS, LIFO is not allowed (LIFO & FIFO are OK under GAAP)
Under IFRS, a write-down of inventory can be reversed (all reversal prohibited under GAAP)
Under IFRS, acquired intangibles must have a future economic benefit that can be reliably measured (Fair Value is OK under GAAP)
Under IFRS, certain development costs can be capitalized and amortized over multiple periods (GAAP expenses as incurred)
