Moving Average Cost Exercise:

Scenario: An oil and gas company purchases natural gas for its operations. They have the following purchase records:

• January 1: 1,000,000 cubic feet (cf) purchased at $3.50 per cf.
• February 15: 500,000 cf purchased at $4.00 per cf.
• March 31: 750,000 cf purchased at $3.75 per cf.

Task: Calculate the weighted average cost per cf of natural gas using the MAC method after each purchase.

Techniques

Chapter 1: Techniques

Moving Average Cost: A Detailed Look at the Technique

The Moving Average Cost (MAC) method is a continuous inventory valuation technique that uses a weighted average cost for each purchase. This average cost is calculated by dividing the total cost of inventory by the total number of units on hand.

Here's a breakdown of the key steps involved in implementing MAC:

1. Calculate the initial average cost: This is done by dividing the cost of the first purchase by the number of units purchased.
2. Calculate the weighted average cost after each purchase: This involves considering the total cost of inventory (including the previous purchase) and the total number of units on hand.
3. Use the weighted average cost to value inventory: The most recent weighted average cost is applied to both the cost of goods sold and the value of ending inventory.

Example:

• Initial Purchase: 100 barrels of crude oil at $60 per barrel = $6,000 total cost
• Average Cost: $6,000 / 100 barrels = $60 per barrel
• Second Purchase: 50 barrels of crude oil at $70 per barrel = $3,500 total cost
• Total Cost of Inventory: $6,000 + $3,500 = $9,500
• Total Number of Barrels: 100 + 50 = 150
• New Weighted Average Cost: $9,500 / 150 = $63.33 per barrel

This calculated weighted average cost of $63.33 per barrel would then be used to value any subsequent sales or to determine the value of remaining inventory.

MAC is especially beneficial in situations where:

• Inventory prices fluctuate frequently.
• A simple and consistent costing method is desired.
• Fairness in inventory valuation is a priority.

Limitations of MAC:

• It may not accurately reflect the true cost of goods sold if there are significant price fluctuations.
• It can be less transparent than other methods, making it difficult to track the exact cost of individual units.

Understanding the intricacies of MAC is crucial for businesses in the oil and gas industry, as it offers a stable and reliable approach to inventory valuation in a volatile market.

Chapter 2: Models

Moving Average Cost Models: Different Approaches to Implementation

The Moving Average Cost (MAC) method can be implemented in different ways, depending on the specific needs of the business. Here are two common models:

1. Periodic Weighted Average Cost:

• This model calculates the weighted average cost at the end of each accounting period, typically at the end of a month, quarter, or year.
• It involves adding up the total cost of all inventory purchases during the period and dividing it by the total number of units purchased.
• This weighted average cost is then used to value both the cost of goods sold and the ending inventory for that period.

2. Perpetual Weighted Average Cost:

• This model calculates the weighted average cost after each purchase, continuously updating the inventory valuation.
• It requires a more sophisticated inventory management system that tracks every purchase and sale in real-time.
• The updated weighted average cost is used to value the cost of goods sold and the ending inventory immediately after each transaction.

Choosing the Right Model:

The choice between periodic and perpetual weighted average cost depends on several factors:

• Frequency of Inventory Purchases: If inventory is purchased frequently, the perpetual model may be more appropriate, ensuring that the inventory valuation reflects the most up-to-date costs.
• Level of Inventory Management Sophistication: The perpetual model requires a more advanced inventory management system that can handle real-time data updates.
• Accuracy Requirements: The perpetual model can provide a more accurate inventory valuation, especially in volatile markets.

Both models provide a stable approach to inventory valuation, but the choice ultimately depends on the specific needs and resources of the oil and gas company.

Chapter 3: Software

Software Solutions for Implementing Moving Average Cost

Implementing the Moving Average Cost (MAC) method effectively requires a robust inventory management system. Specialized software can streamline the process, ensuring accuracy and efficiency in calculating weighted average costs, tracking inventory levels, and generating reports.

Here are some key features to look for in software solutions designed for MAC:

• Inventory Tracking: Software should accurately track all inventory purchases, sales, and adjustments. This includes detailed information about each unit, such as quantity, cost, and date of purchase.
• Weighted Average Cost Calculation: Software should automatically calculate the weighted average cost after each purchase, ensuring real-time updates to inventory valuations.
• Cost of Goods Sold Calculation: Software should be able to determine the cost of goods sold for each sale, using the most recent weighted average cost.
• Inventory Valuation Reports: Software should generate comprehensive reports on inventory value, cost of goods sold, and other relevant metrics. These reports should be customizable to meet specific reporting needs.

Examples of Software Solutions:
