Reserves Valuation for Ad Valorem Taxes
For clients with small oil and gas reserves, IPT offers annual reserves valuation services to support state and local property tax filings, commonly referred to as ad valorem taxes. The objective is to determine the fair market value of the reserves as of January 1st (or another statutory valuation date), which is then used to calculate the upcoming year’s property tax liability.
IPT provides a concise valuation report that estimates the value of the client’s oil and gas interests, typically broken down by lease or well. The focus is on producing assets, specifically Proved Developed Producing (PDP) reserves. To keep the process cost-effective, IPT uses simplified reserve estimates or decline curve analysis when production data is available.
Valuations are typically based on a Discounted Cash Flow (DCF) model that projects future net cash flow from the reserves and applies a standard discount rate, generally between 10% and 12%, consistent with what many appraisal districts use. The model incorporates recent production data, a realistic commodity price deck (such as a trailing 12-month average or adjusted strip prices), and accounts for typical operating costs and severance taxes.
All valuation results are formatted to align with the requirements of state or county tax forms and can be submitted either by IPT or by the client, depending on the local filing procedures.
Reserves Valuation for Ad Valorem Taxes (Expanded Definitions)
A Latin phrase meaning “according to value.” In oil and gas, ad valorem taxes are annual property taxes assessed by state or local governments based on the fair market value of mineral interests as of a statutory date (often January 1st).
The process of estimating the economic value of oil and gas reserves. For ad valorem purposes, valuations are used to determine tax liability, not for investment or estate planning.
The estimated price that a property would sell for on the open market between a willing buyer and seller, both having reasonable knowledge of the facts. Taxing authorities require FMV as the basis for ad valorem assessments.
Reserves that are actively producing from existing wells and facilities. Because these reserves are generating revenue, they are the primary focus of ad valorem valuations.
A method of forecasting future oil and gas production by analyzing historical production trends and projecting the rate of decline over time. This is a cost-effective approach for smaller properties.
A valuation method that projects future revenues and expenses from reserves and discounts those cash flows back to present value using a discount rate. This approach reflects both the time value of money and the risk associated with the reserves.
The rate used to reduce future cash flows to their present value. For ad valorem taxes, discount rates commonly fall between 10% and 12%, aligning with appraisal district practices.
The set of assumed oil, gas, and NGL prices used for forecasting revenues. For ad valorem valuations, this often includes a 12-month trailing average or adjusted strip pricing that reflects recent commodity trends.
The routine expenses required to produce oil and gas, including labor, utilities, repairs, and field services. Operating costs are subtracted from revenues when calculating taxable net income.
State-imposed taxes on the extraction of oil and gas. These are deducted in valuation models before determining net cash flow.
The official date on which the property’s value is determined for tax purposes (often January 1st). All reserve and economic assumptions must reflect conditions as of this date.
