All right. Let's discuss some of the differences between GAAP and IFRS when it comes to inventories. So, inventories here, remember, when we talk about GAAP, that's what we focus on in this course. These are the Generally Accepted Accounting Principles and those are the rules here in the U.S. that we follow. They are set by the Financial Accounting Standards Board (FASB). They set GAAP, and those are the rules that we're focused on when we talk about different issues in this course. But, for the most part, we've got a lot of similarities with the international standards, which are set by the International Accounting Standards Board and they create IFRS, the International Financial Reporting Standards. Cool? So let's go ahead and focus on the differences here when it comes to inventory. Let's start with the similarities. We'll see that the initial purchase is always at historical cost, just like we learned. Whatever we paid for the inventory, well, that's going to be the cost of the inventory. Initial purchase at historical cost, straightforward. That's going to be the same for both, but then we have our subsequent valuations, which are also similarly done with that lower of cost or market method that we learned, right? Lower of cost or market, so if the market value has decreased, well, we should decrease the value of our inventory. That's the same between GAAP and IFRS.
Another similarity, we've got the ownership of goods. Remember when we talked about Free On Board (FOB) destination and Free On Board (FOB) shipping point? Well, that's when we use a shipping company. Who owns the goods? At what point does the ownership transfer? Well, that's the same rules that we follow when it comes to GAAP and IFRS. Some of the main differences here, and this is a big one, is that IFRS prohibits LIFO. You're not allowed to use the LIFO method when you do IFRS for your inventory, okay? So that's a big difference between GAAP and IFRS. They don't allow LIFO, and that's because LIFO, it kind of is a little weird, right? Because we're taking our latest cost that we have and those are the ones we're assigning to the cost of goods sold. And we have these old values that kind of just sit on the books. Remember, IFRS likes to think about the fair values and it wants those inventories to reflect more closely what they're actually worth today, okay? And that's why they prohibit LIFO because that means that you keep selling the new ones and those keep going to your cost of goods sold and the old ones just stay on your books.
Then, the lower cost or market calculation, though they both use the lower of cost or market, the way they treat the rules is a little differently. GAAP uses replacement cost. Okay? Replacement cost on the market? Whereas IFRS uses this idea of net realizable value, where it takes what you could sell it for and it subtracts any selling cost that you might have related to selling that inventory. Okay? So you don't have to get caught up in the calculations of lower cost or market. You can just focus on what we learned in our lower cost or market video. But this is a difference, so you can see that there's a small difference when they're calculating lower cost or market, but this principle remains the same of making sure that you're updating that inventory value if we think that it's been devalued, okay? So that's about it here for the GAAP and IFRS differences. Let's go ahead and move on to the.
