ASC 930: Depletion Expense Journal Entries for Extractive Activities - Mining

Posted In | ASC Education | Gridlex Academy

Accounting Standards Codification (ASC) Topic 930, "Extractive Activities - Mining," provides guidance on accounting for depletion expense in the mining industry. Depletion is a method of allocating the cost of a natural resource, such as minerals or oil, over its expected useful life or production period. Proper accounting for depletion expense is essential to accurately reflect the mining company's financial position and performance. This article will explain the concept of depletion expense transactions under ASC 930 and provide examples of journal entries that illustrate the proper accounting treatment for these transactions.

 

Depletion Expense Transaction

Depletion expense is the systematic allocation of the cost of a natural resource over its estimated useful life or production period. For mining companies, this expense reflects the consumption of the mineral resources that are extracted from the ground. Under ASC 930, mining companies are required to use the units-of-production method of depletion, which calculates the depletion expense based on the quantity of resources extracted during a given period relative to the total estimated quantity of recoverable resources.

 

Journal Entries for Depletion Expense Transaction

To better understand the accounting treatment for depletion expense transactions, let's look at a hypothetical example.

 

Example:

Mining Company L acquires mineral rights for a cost of $10 million. The company estimates that the mineral deposit contains 1 million tons of recoverable minerals.

 

Journal Entry 1: Record the acquisition of mineral rights

Mining Company L would record the initial acquisition of the mineral rights as follows:

 

Debit: Mineral Rights $10 million

Credit: Cash $10 million

 

The debit to mineral rights represents the cost of the asset, while the credit to cash represents the cash outflow for the purchase.

 

Journal Entry 2: Record the depletion expense

Next, Mining Company L extracts 50,000 tons of minerals during the first year of operation. The company would calculate the depletion expense for the year as follows:

 

Depletion expense per ton = Cost of mineral rights / Total estimated recoverable resources

Depletion expense per ton = $10 million / 1 million tons

Depletion expense per ton = $10

 

Annual depletion expense = Depletion expense per ton × Quantity of resources extracted during the year

Annual depletion expense = $10 × 50,000 tons

Annual depletion expense = $500,000

 

Mining Company L would record the annual depletion expense as follows:

Debit: Depletion Expense $500,000

Credit: Accumulated Depletion - Mineral Rights $500,000

 

The debit to depletion expense represents the annual depletion expense, which is recognized in the income statement. The credit to accumulated depletion - mineral rights reflects the accumulated depletion on the mineral rights, which is presented as a contra-asset account in the balance sheet.
 

ASC 930 provides guidance on accounting for depletion expense in the mining industry, ensuring that mining companies accurately allocate the cost of natural resources over their estimated useful life or production period. By following the principles outlined in ASC 930, mining companies can properly account for depletion expense transactions and provide useful information to investors and other stakeholders. It is essential for accountants and financial professionals to understand and apply the principles of ASC 930 when dealing with depletion expense transactions in the mining industry in order to maintain compliance with accounting standards and provide accurate financial information to stakeholders.
