Intangible Drilling Costs
Expenses a company has when it drills for oil or natural gas. Intangible drilling costs are sometimes convenient for a company's tax purposes because it can deduct intangible drilling costs in one year when the company perhaps found little or no oil from profits made in a different year when the company does find oil.
Interest During Construction
In project finance, the interest that accumulates on a loan that finances the construction of a building or development. The IDC is a cost for the project, though it is not always calculated as such. The IDC is calculated until the project begins to generate revenue, when the company financing the project begins to service its debts.
