Amortization

Deductible expense allowed as a means of spreading the cost of an intangible asset over a period of years. For instance, if you pay points to take out a home equity loan and the loan proceeds are not used for home improvements, you cannot deduct all the points in the year paid. Instead, you divide the cost of the points by the length of the loan and deduct only the amount that applies to the current year. (from MSN.com)
