The change in goodwill was due to currency translation adjustments. Other than non-amortizable goodwill and tradename, intangible assets are amortized on a straight-line basis. Customer relationships are amortized over periods ranging from 10 years to 14 years and technology and related intangible assets are amortized over periods ranging from 14 years to 20 years.
