FIFO : Premier Entré, Premier Sorti - Un Principe Clé dans la Comptabilité des Stocks Pétroliers et Gaziers
Dans le monde volatil et complexe du pétrole et du gaz, une gestion méticuleuse des stocks est cruciale. L'un des principes fondamentaux qui régissent ce processus est le **Premier Entré, Premier Sorti (FIFO)**. Cette méthode, souvent utilisée en comptabilité des stocks, suppose que les **unités les plus anciennes en stock sont les premières à être vendues ou utilisées**, quelle que soit l'ordre physique réel du retrait.
Voici une explication de FIFO dans le contexte du pétrole et du gaz :
**Fonctionnement :**
- Imaginez un réservoir de stockage rempli de pétrole brut acheté à différents prix au fil du temps.
- Lorsque le pétrole est extrait du réservoir pour être transformé ou vendu, FIFO dicte que le coût attribué à ce pétrole est le coût du lot acheté le plus tôt, même si le pétrole extrait provient d'un achat plus récent.
**Exemple :**
- **Achat 1 :** 100 barils de pétrole brut à 50 $ le baril (coût total = 5 000 $).
- **Achat 2 :** 200 barils de pétrole brut à 60 $ le baril (coût total = 12 000 $).
- **Vente :** 150 barils de pétrole brut.
Selon FIFO, le coût des 150 barils vendus serait calculé comme suit :
- **100 barils à 50 $/baril = 5 000 $** (du premier achat)
- **50 barils à 60 $/baril = 3 000 $** (du deuxième achat)
**Coût Total des Marchandises Vendues = 8 000 $**
**Avantages de FIFO :**
- **Simple à comprendre et à appliquer :** Sa nature directe la rend facile à comprendre pour les comptables et les gestionnaires.
- **Reflète le flux réel des marchandises :** Dans la plupart des cas, les entreprises vendent effectivement les stocks les plus anciens en premier, ce qui correspond au mouvement réel des marchandises.
- **Coût des marchandises vendues plus faible en période d'inflation :** FIFO entraîne un coût des marchandises vendues plus faible en période de hausse des prix, ce qui conduit à des bénéfices plus élevés. En effet, les unités les plus anciennes et les moins chères sont utilisées en premier.
**Limitations de FIFO :**
- **Peut ne pas refléter le flux physique réel :** Si les unités les plus anciennes ne sont pas physiquement extraites en premier, FIFO peut ne pas représenter fidèlement le mouvement réel des stocks.
- **Peut entraîner des bénéfices gonflés en période d'inflation :** Alors qu'il peut conduire à des bénéfices plus élevés en période d'inflation, il peut également surestimer la valeur réelle des stocks au bilan.
**Comparaison avec LIFO (Dernier Entré, Premier Sorti) :**
FIFO est souvent comparé au **Dernier Entré, Premier Sorti (LIFO)**, une autre méthode de calcul du coût des stocks. LIFO suppose que le stock le plus récent est vendu en premier. LIFO conduit à un coût des marchandises vendues plus élevé en période d'inflation, ce qui entraîne des bénéfices plus faibles. Bien qu'il soit autorisé aux États-Unis, LIFO n'est pas aussi largement utilisé à l'international que FIFO.
**Conclusion :**
FIFO est une méthode largement utilisée et acceptée pour l'évaluation des stocks dans le secteur pétrolier et gazier. Sa simplicité, sa facilité de mise en œuvre et sa réflexion sur le flux naturel des marchandises en font un outil précieux pour la gestion des stocks et la détermination de l'exactitude des états financiers. Toutefois, il est crucial de comprendre ses limitations et son impact potentiellement trompeur sur les bénéfices en période d'inflation.

FIFO Exercise:
Scenario:
An oil and gas company has the following purchases of crude oil:
- January 1st: 500 barrels at $45 per barrel
- February 15th: 300 barrels at $50 per barrel
- March 10th: 400 barrels at $55 per barrel
On March 20th, the company sold 600 barrels of crude oil.
Task: Calculate the cost of goods sold for the 600 barrels using the FIFO method.
Exercice Correction
**Step 1:** Identify the oldest inventory units. In this case, the 500 barrels purchased on January 1st are the oldest. **Step 2:** Allocate the oldest inventory to the sale. Since the company sold 600 barrels, the entire January 1st purchase (500 barrels) and 100 barrels from the February 15th purchase will be used. **Step 3:** Calculate the cost of goods sold: * 500 barrels @ $45/barrel = $22,500 * 100 barrels @ $50/barrel = $5,000 **Total Cost of Goods Sold = $27,500**

Chapter 1: Techniques
FIFO: First In, First Out - A Key Principle in Oil & Gas Inventory Accounting
In the volatile and complex world of oil and gas, meticulous inventory management is crucial. One of the most fundamental principles governing this process is First In, First Out (FIFO). This method, often used in inventory accounting, assumes that the oldest units in stock are the first ones to be sold or used, regardless of the actual physical order of withdrawal.
How FIFO Works:
Imagine a storage tank filled with crude oil purchased at different prices over time. When oil is extracted from the tank for processing or sale, FIFO dictates that the cost assigned to this oil is the cost of the earliest purchased batch, even if the extracted oil came from a later purchase.
Example:
- Purchase 1: 100 barrels of crude oil at $50 per barrel (total cost = $5,000).
- Purchase 2: 200 barrels of crude oil at $60 per barrel (total cost = $12,000).
- Sale: 150 barrels of crude oil.
According to FIFO, the cost of the 150 barrels sold would be calculated as follows:
- 100 barrels @ $50/barrel = $5,000 (from the first purchase)
- 50 barrels @ $60/barrel = $3,000 (from the second purchase)
Total Cost of Goods Sold = $8,000
FIFO in Oil & Gas:
FIFO is widely used in the oil & gas sector due to its simplicity and alignment with the natural flow of goods. This method helps companies:
- Track inventory movements: By assuming the oldest units are sold first, FIFO provides a clear picture of inventory turnover.
- Calculate cost of goods sold: This is essential for determining profit margins and making informed business decisions.
- Manage inventory levels: FIFO helps companies understand how much inventory they have on hand and make adjustments as needed.
Summary:
FIFO is a key technique in oil & gas inventory accounting that provides a simple and transparent approach to tracking inventory flow and calculating costs. Its simplicity and adherence to the natural flow of goods make it a valuable tool for inventory management and financial reporting in the industry.
