The cumulative amount of the estimated future tax effects attributable to the difference between the tax basis of fixed assets and intangible assets, and the basis of fixed assets and intangible assets computed in accordance with generally accepted accounting principles. The difference in basis, whether due to amortization or other reasons, will increase future taxable income when such difference reverses. Intangible assets include, but are not limited to, assets such as patents, trademarks and customer lists.
