NOTE F -INTANGIBLE ASSETS

In accordance with ASC 350, “Intangibles—Goodwill and Other”, goodwill and other intangible assets deemed to have indefinite lives are not amortized, but are subject to annual impairment tests. The Company reviews and evaluates its goodwill and indefinite life intangible assets for potential impairment at a minimum annually or more frequently if circumstances indicate that impairment is possible.

The Company determined the fair value of assets acquired and liabilities assumed using a variety of methods. An income approach based on discounted cash flows was used to determine the values of our trademarks, customer relationships and FAA certifications. The assumptions we used to estimate the fair value of our reporting units are based on historical performance, as well as forecasts used in our current business plan and require considerable management judgment.
