These amounts are determined by considering the impact of the hypothetical interest rates on our borrowing cost and our interest rate swap agreements in effect on December 31, 2003. These analyses do not consider the effects of the reduced level of overall eco- nomic activity that could exist in such an environment. Further, in the event of a change of such magnitude, we would consider taking actions to further mitigate our exposure to the change. However, due to the uncertainty of the specific actions that would be taken and their possible effects, the sensitivity analysis assumes no changes in our capital structure. 

We have exposure to equity price market risk because of our equity investments in certain publicly-traded companies and privately held entities. We classify investments in publicly-traded companies as available-for-sale and, consequently, record them on our bal- ance sheet at fair value with unrealized gains or losses reported as a component of comprehensive income or loss. Investments in privately held entities are generally accounted for under the cost method because we do not influence any of the operating or finan- cial policies of the entities in which we invest. For all investments, we recognize other than temporary declines in value against earnings in the same period the decline in value was deemed to have occurred. In 2002, we recorded non-cash impairment charges of $2,545,000 to write down certain investments for which we deemed the decline in fair value to be other than temporary. There is no assurance that future declines in values will not have a material adverse impact on our future results of operations. By way of example, a 10% decrease in the fair value of our equity investments as of December 31, 2003 would decrease their fair value by approximately $4.7 million.
