1. 740-932Extractive Activities—Oil and Gas740 Income Taxes

   This subtopic covers income tax accounting peculiar to oil- and gas-producing activities. Its core rules: the tax benefit of statutory depletion in excess of cost depletion is recognized only in the period the excess is deducted on the tax return (no deferred tax asset before then), and the likelihood that future statutory depletion will reduce or eliminate future taxable income must be weighed in the more-likely-than-not realizability assessment for deferred tax assets. It also notes that costs such as intangible drilling and development costs and geological and geophysical costs are deducted for tax purposes in periods different from when they are expensed or amortized for book purposes, creating temporary differences.
