11.9 Natural Resources and Depletion
Natural resources, such as oil, minerals, and timber, are critical assets for many businesses, especially those in the extraction and forestry industries. Accounting for these resources involves specific principles and methods to ensure accurate financial reporting. This section delves into the accounting treatment of natural resources, focusing on the concept of depletion, which is akin to depreciation for tangible assets. We will explore the methods of calculating depletion, the impact on financial statements, and the relevant Canadian accounting standards.
Understanding Natural Resources in Accounting
Natural resources are assets that are physically consumed when used. Unlike other long-lived assets, natural resources are extracted and sold, leading to their eventual depletion. These resources are recorded as assets on the balance sheet, and their value is systematically reduced over time as they are used up.
Types of Natural Resources
- Minerals: Includes resources such as gold, silver, coal, and other mined materials.
- Oil and Gas: Hydrocarbons extracted from the earth, crucial for energy production.
- Timber: Trees harvested for wood and paper products.
- Other Resources: Includes water, natural gas, and other extractive resources.
The Concept of Depletion
Depletion is the process of allocating the cost of natural resources over their useful life. It is similar to depreciation but specifically applies to natural resources. Depletion expense is recognized in the income statement, reflecting the consumption of the resource.
Depletion Methods
There are two primary methods for calculating depletion:
-
Cost Depletion: This method involves allocating the total cost of the resource over its estimated recoverable units. The formula is:
$$
\text{Depletion Expense} = \left( \frac{\text{Cost of Resource} - \text{Residual Value}}{\text{Total Estimated Recoverable Units}} \right) \times \text{Units Extracted During the Period}
$$
-
Percentage Depletion: This method allows a fixed percentage of gross income from the resource to be deducted as depletion. It is often used in the oil and gas industry and is subject to specific tax regulations.
Accounting for Depletion
Initial Recognition
When a natural resource is acquired, it is recorded at cost. This cost includes the purchase price, exploration costs, development costs, and any other expenses necessary to prepare the resource for extraction.
Journal Entries for Depletion
To record depletion, the following journal entry is typically made:
- Debit: Depletion Expense
- Credit: Accumulated Depletion
This entry reduces the book value of the natural resource and recognizes the expense in the income statement.
Example
Consider a mining company that acquires a mineral deposit for $10 million, with an estimated 1 million tons of extractable ore. In the first year, 100,000 tons are extracted. The depletion expense for the year would be:
$$
\text{Depletion Expense} = \left( \frac{10,000,000}{1,000,000} \right) \times 100,000 = \$1,000,000
$$
The journal entry would be:
- Debit: Depletion Expense $1,000,000
- Credit: Accumulated Depletion $1,000,000
Financial Reporting and Disclosure
Balance Sheet
Natural resources are reported as non-current assets on the balance sheet. The accumulated depletion is deducted from the cost of the resource to determine its book value.
Income Statement
Depletion expense is reported as an operating expense, reducing the company’s net income.
Notes to Financial Statements
Companies must disclose the methods used for calculating depletion, the total depletion expense for the period, and any significant assumptions or estimates.
Regulatory Framework
Canadian Accounting Standards
In Canada, the accounting for natural resources is governed by the International Financial Reporting Standards (IFRS) and the Accounting Standards for Private Enterprises (ASPE). Key standards include:
- IFRS 6: Exploration for and Evaluation of Mineral Resources
- IAS 16: Property, Plant, and Equipment (for development costs)
- IAS 36: Impairment of Assets
Compliance Considerations
Companies must ensure compliance with these standards, including accurate estimation of recoverable units, proper allocation of costs, and timely recognition of impairment.
Challenges and Best Practices
Estimation of Recoverable Units
Estimating the total recoverable units of a resource can be challenging due to geological uncertainties. Companies should use the best available data and regularly update estimates.
Environmental and Legal Considerations
Accounting for natural resources must consider environmental regulations and legal obligations, such as land restoration and pollution control.
Technological Advances
Advancements in extraction technology can affect the recoverable units and the cost of extraction, impacting depletion calculations.
Practical Example: Case Study
Consider a Canadian oil company that acquires a new oil field. The company estimates 5 million barrels of recoverable oil and incurs $50 million in exploration and development costs. In the first year, 500,000 barrels are extracted.

Calculate Depletion Expense:
$$
\text{Depletion Expense} = \left( \frac{50,000,000}{5,000,000} \right) \times 500,000 = \$5,000,000
$$
-
Journal Entry:
- Debit: Depletion Expense $5,000,000
- Credit: Accumulated Depletion $5,000,000
-
Financial Statement Impact:
- Balance Sheet: The book value of the oil field is reduced by $5,000,000.
- Income Statement: Operating expenses increase by $5,000,000, reducing net income.
Conclusion
Accounting for natural resources and depletion is a critical aspect of financial reporting for companies in the extraction industries. Understanding the methods of depletion, regulatory requirements, and best practices ensures accurate and compliant financial statements. As you prepare for the Canadian Accounting Exams, focus on the principles and calculations involved in depletion, and consider the broader implications of resource management and sustainability.
