Rather, the amount simply reflects an ongoing reduction in the amount of the original recorded cost of the natural resources. This feature serves as a long-standing tax incentive designed to encourage investment and development in the domestic natural resources sector. Depletion specifically applies to natural resources, which are physically consumed through extraction and are non-renewable. For a resource company, the depletion expense can represent a significant portion of the total cost of goods sold.
For that purpose, property is each separate interest businesses own in each mineral deposit in each separate tract or parcel of land. If positive charge Q is placed on gate with area A, then holes are depleted to a depth w exposing sufficient negative acceptors to exactly balance the gate charge. A more complete analysis would take into account that there are still some carriers near the edges of the depletion region. The depletion region is not symmetrically split between the n and p regions – it will tend towards the lightly doped side.
Eligible for Expenses
By crediting the Accumulated Depletion account instead of the asset account (E.g. Coal Mine Assets), we continue to report the original cost of the entire natural resource on the financial statements. In addition, Pensive Oil estimates it will incur a site restoration cost of $57,000 once extraction is complete, making the total depletion base of the property $600,000. As you revise your estimates of the remaining amount of extractable natural resource, incorporate these estimates into the unit depletion rate for the remaining amount to be extracted. The estimated amount of a natural resource that can be recovered will change constantly as assets are gradually extracted from a property. Thus, if you extract 500 barrels of oil and the unit depletion rate is $5.00 per barrel, then you charge $2,500 to depletion expense. The resulting net carrying amount of natural resources still on the books of a business does not necessarily reflect the market value of the underlying natural resources.
The future of accounting is therefore closely linked to the future of the environment. This requires a deep understanding of the financial implications of environmental issues. This shift has been accelerated by recent changes in accounting standards, which now require organizations to report on their environmental impact. For example, assume a company has 1 million barrels of oil in a reserve. While depletion can be a useful tool for businesses, there are some potential drawbacks to consider. For example, if water is injected into the reservoir at too high a rate, it can push oil and gas out of the well and into the surrounding environment.
Electric field in depletion layer and band bending
From a full depletion analysis as shown in figure 2, the charge would be approximated with a sudden drop at its limit points which in reality is gradual and is explained by Poisson’s equation. Due to the majority charge carrier diffusion described above, the depletion region is charged; the N-side of it is positively charged and the P-side of it is negatively charged. As a result, majority charge carriers (free electrons for the N-type semiconductor, and holes for the P-type semiconductor) are depleted in the region around the junction interface, so this region is called the depletion region or depletion zone. In semiconductor physics, the depletion region, also called depletion layer, depletion zone, junction region, space charge region, or space charge layer, is an insulating region within a conductive, doped semiconductor material where the mobile charge carriers diffuse, or have been forced away by an electric field.
For example, adopting technologies that recycle water used in mining operations or implementing energy-efficient methods in oil extraction can help reduce the depletion rate and make the process more sustainable. Underestimating resources can lead to premature depletion while overestimating can result in inflated financial reports. Additionally, depletion provides a tax advantage for what is depletion in accounting businesses in resource-extraction industries. Percentage depletion is another method used to calculate depletion, but it is generally applied for tax purposes rather than regular accounting practices. This method ensures that the cost of the resource is matched to the revenue generated from its sale, and that the expense is recognised over the life of the resource.
Depreciation, depletion, and amortization (DD&A)
This condition ensures that the net negative acceptor charge exactly balances the net positive donor charge. If the gate material is polysilicon of opposite type to the bulk semiconductor, then a spontaneous depletion region forms if the gate is electrically shorted to the substrate, in much the same manner as described for the p–n junction above. (In this device there is a limit to how wide the depletion width may become. It is set by the onset of an inversion layer of carriers in a thin layer, or channel, near the surface. The above discussion applies for positive voltages low enough that an inversion layer does not form.) They leave behind a depleted region that is insulating because no mobile holes remain; only the immobile, negatively charged acceptor impurities. If a positive voltage now is applied to the gate, which is done by introducing positive charge Q to the gate, then some positively charged holes in the semiconductor nearest the gate are repelled by the positive charge on the gate, and exit the device through the bottom contact.
- It assigns a fixed percentage to gross revenue—sales minus costs—to allocate expenses.
- The depletion rate per unit is calculated by dividing the depletion base minus salvage value by the total units to be recovered.
- Exploration costs refer to the expenses incurred while searching for natural resources.
- These costs are capitalized and depleted across multiple accounting periods.
- Depletion is similar to depreciation, but it applies to natural resources such as oil, gas, and minerals.
- Cost depletion is an accounting method by which costs of natural resources are allocated to depletion over the period that make up the life of the asset.
- Changes in estimates related to useful life, residual value, or recoverable reserves do not affect previously recorded depreciation, depletion, or amortization.
Cost depletion
- Depletion and depreciation are both methods of cost allocation, but they apply to different types of assets.
- Cost depletion allocates the costs of extracting natural resources as operating expenses, which can lower pre-tax income.
- The extraction costs increase is always accompanied by the natural resource amount decrease.
- For instance, the deduction is capped at a certain level, and the percentage varies based on the resource type and local regulations.
- When an inversion layer forms, the depletion width ceases to expand with increase in gate charge Q.
- Conceptually, depletion is similar to the depreciation of property, plant and equipment.

Conceptually, depletion is similar to the depreciation of property, plant and equipment. This article will define depletion, explain its significance in accounting, and provide examples of how it’s calculated and applied. Stakeholders, including investors, consumers, and regulators, will demand more detailed reporting on how depletion is being managed and whether businesses are adopting responsible extraction practices.
How to Record Depletion Expenses
The percentage depletion approach needs multiple calculations and is thus not a form of depletion that is highly dependent upon or embraced. Just like depreciation and amortisation, depletion is a non-cash expense. Thus, statement users can see the percentage of the resource that has been removed.
This rate is found by dividing the total cost base by the estimated total recoverable units. This base includes the initial acquisition costs for land rights or mineral leases, along with exploration costs required to locate the resource. The total cost forming the “depletable base” is a composite of several expenditures necessary to bring the resource to market.
For tax purposes, the two types of depletion are percentage depletion and cost depletion. It requires the method that yields the highest deduction to be used with mineral property, which it defines as oil and gas wells, mines, and other natural deposits, including geothermal deposits. Cost depletion is calculated by taking the property’s basis, total recoverable reserves and number of units sold into account. It assigns a fixed percentage to gross revenue—sales minus costs—to allocate expenses.
Once the cost per unit is known, the company multiplies this cost by the number of units extracted during the accounting period to determine the depletion expense for that period. The depletion expense recorded in each period reflects the proportion of the resource extracted and the related costs allocated for that period. Exploration costs refer to the expenses incurred while searching for natural resources. Depreciation, depletion, and amortization (DD&A) is an accounting method that lets companies gradually expense economic resources over time to align costs with revenues.
Natural resources represent inventories of raw materials that can be consumed (exhausted) through extraction or removal from their natural setting (e.g. removing oil from the ground). On the balance sheet, we classify natural resources as a separate group among noncurrent assets under headings such as “Timber Stands” and “Oil Reserves”. The depletion rate is depletion expense divided by units extracted during the year. This gives a company an idea of how much its natural resources are worth and how quickly they are being consumed. The purchase price or cost of the resources, mineral rights, and anything needed to prep the area for extraction is then allocated over the period of time they are consumed.
It’s similar to depreciation, but instead of applying to physical assets, depletion applies to natural resources such as oil, gas, timber, and minerals. Sustainable resource management will help reduce the depletion of natural resources and protect the environment, mitigating the long-term impacts of over-extraction. Managing depletion expenses for businesses involved in natural resource extraction is crucial for maintaining profitability. Depletion in accounting is a concept primarily used in industries that extract natural resources, such as oil, gas, minerals, and timber. Overall, depletion is a useful calculation in accounting for a business that sells natural resources. Cost depletion is computed by estimating the total quantity of mineral or other resources acquired and assigning a proportionate amount of the total resource cost to the quantity extracted in the period.
Where depletion differs is that it refers to the gradual exhaustion of natural resource reserves, as opposed to the wearing out of depreciable assets or aging life of intangibles. Producer X has a property with $40,000 in capitalized costs, which includes the lease bonus, exploration costs, and carrying costs. The depletion rate per unit is calculated by dividing the depletion base minus salvage value by the total units to be recovered. As you extract oil, you’ll subtract the number of barrels extracted from the total recoverable reserves. The units-of-production method is commonly used to calculate depletion.
Resources supplied by nature, such as ore deposits, mineral deposits, oil reserves, gas deposits, and timber stands, are natural resources or wasting assets. Under this method, the depletion expense is allocated based on the percentage of reserves that have been drawn down during the period. Depletion is most commonly used in the mining and forestry industries, but can also be applied to oil and gas wells, quarries, and other natural resources. Depletion is used for natural resources such as minerals, oil, and timber, reflecting their gradual exhaustion.
