Other Intangible Assets

Intangible assets are primarily amortized over periods ranging from approximately 1 to 10 years. The weighted-average period of amortization for all intangible assets as of December 31, 2011, is 7.3 years. The customer-related intangible assets, which consist of customer contracts, backlog, and non-contractual customer relationships, related to the acquisitions are being amortized based on estimated cash flows and respective estimated economic benefit of the assets. The weighted-average period of amortization of the customer-related intangibles is 7.4 years. Intangible assets related to acquired developed technology are being amortized on an accelerated basis over a weighted-average period of 5.8 years.
