The Last-In, First-Out (LIFO) method of inventory costing is not allowed by IFRS (International Financial Reporting Standards) or PFRS (Philippine Financial Reporting Standards).
The LIFO method permitted under U.S. GAAP is not permitted under IFRS. Any organization using the LIFO inventory method for book and tax purposes would need to select a different method as part of its conversion to IFRS, which could result in a significant tax impact.
Choosing the Right Inventory Valuation Method
The main difference between International Financial Reporting Standards (IFRS) and US Generally Accepted Accounting Principles (GAAP) is that IFRS does not allow the LIFO method.
Both GAAP and IFRS allow First In, First Out (FIFO), weighted-average cost, and specific identification methods for valuing inventories. However, GAAP also allows the Last In, First Out (LIFO) method, which is not allowed under IFRS.
As LIFO inventory costing is not permitted under IFRS, companies that utilize the LIFO costing methodology under US GAAP might experience significantly different operating results as well as cash flows.
Investors understand that older costs leave first, making the income statement easier to read. If you sell across borders, IFRS requires FIFO or weighted average—never LIFO.
The LIFO method is available only under U.S. Generally Accepted Accounting Principles (GAAP) — it's not permitted under International Financial Reporting Standards (IFRS).
LIFO is allowed under GAAP in the U.S. but prohibited under IFRS followed outside the U.S. FIFO is considered the better method for accurately presenting inventory costs and profits. But U.S. firms can elect to use LIFO for tax benefits provided they meet GAAP reporting requirements.
LIFO is banned under IFRS due to potential financial distortions. LIFO can understate company earnings and lead to outdated inventory values. Under LIFO, tax liabilities are reduced but at the cost of outdated inventory values.
IAS 2 prohibits LIFO; US GAAP allows its use.
The International Accounting Standards Board (IASB® Board) eliminated the use of LIFO because of its lack of representational faithfulness of inventory flows.
GAAP (US Standard) permits all four costing methods: FIFO, LIFO, Weighted Average, and Specific Identification. IFRS (International Standard) prohibits LIFO entirely, requiring businesses to use FIFO, Weighted Average, or Specific Identification.
LIFO costing is actually banned under International Financial Reporting Standards (IFRS) and its use is restricted under Generally Accepted Accounting Principles (GAAP).
IFRS mandates that LIFO is not a permissible method of inventory cost calculation or recognizing cost as an expense under the International Accounting Standards (IAS) – 2. LIFO is prohibited because it creates a misleading picture of an organization's financial statements and profitability.
The complete form of LIFO is last in, first out. IFRS prohibits LIFO due to potential distortions. It can understate a company's earnings or profits to keep taxable income low. Under this method, the valuation of inventory can be outdated.
The four most common inventory costing methods are:
FIFO. LIFO. Weighted average. Specific identification.
LIFO is not permitted by IFRS, but it is still acceptable in the US. In situations with both rising costs and increasing inventory levels, LIFO results in the higher, more recent costs flowing through cost of sales with the lower, older costs in inventories.
LIFO in Accounting Standards
Under IFRS and ASPE, the use of the last-in, first-out method is prohibited. However, under GAAP, the use of Last-In First-Out is permitted. The inventory valuation method is prohibited under IFRS and ASPE due to potential distortions on a company's profitability and financial statements.
Globally accepted: FIFO is allowed under Generally Accepted Accounting Principles (GAAP) in the United States and International Financial Reporting Standards (IFRS).
GAAP allows LIFO, FIFO, and weighted-average methods, while IFRS prohibits LIFO. IFRS measures inventory at the lower of cost or net realizable value. Only IFRS allows reversals of inventory write-downs; GAAP prohibits it. GAAP provides leeway for inventory costing methods, while IFRS is more consistent.
LIFO is permitted under US GAAP and is often used by US companies because, during periods of inflation, it results in a higher Cost of Goods Sold (COGS) and a lower Net Income. This leads to lower taxable income and hence, lower tax payments, which is a major incentive for its use in the USA.
Direct Write-off Method: General accepted accounting principles (GAAP) do not recognized the direct write-off method. Under the direct write-off method, bad debt expense is recorded when the customer's account is determine to be uncollectible.
In addition, there are certain accounting treatments that are not allowable under the SMEs Standard. Examples of these disallowable treatments are the revaluation model for property, plant and equipment and intangible assets, and proportionate consolidation for investments in jointly controlled entities.
LIFO is prohibited by the IFRS because it can misrepresent a business's financial statements – particularly its income statement and balance sheet.
The four main types of inventory are Raw Materials (components for production), Work-in-Progress (WIP) (partially finished goods), Finished Goods (ready for sale), and Maintenance, Repair, & Overhaul (MRO) Supplies (items for operational upkeep). Managing these categories effectively helps businesses control costs, streamline operations, and meet customer demand efficiently.
The guidance in IFRS 13 does not apply to transactions dealt with by certain IFRS® Accounting Standards, for example, share-based payment transactions in IFRS 2 Share-based Payment, leasing transactions in IFRS 16 Leases, or to measurements that are similar to fair value but are not fair value, for example, net ...
