The intangible assets that are amortizable have estimated useful lives of two to eight years. During the three months ended March 31, 2013, the Company capitalized $0.4 million related to software development costs. During the nine months ended March 31, 2013, the Company capitalized $1.6 million related to software development costs and purchased $0.3 million of patents.

Research and development costs are expensed as incurred. In accordance with ASC 985-20, Costs of Computer Software to be Sold, Leased, or Marketed, development costs of computer software to be sold, leased, or otherwise marketed are subject to capitalization beginning when a product's technological feasibility has been established and ending when a product is available for general release to customers. Such costs are amortized using the straight-line method over the estimated economic life of the product. The Company evaluates the realizability of the assets and the related periods of amortization on a regular basis. Judgment is required in determining when technological feasibility of a product is established as well as its economic life. In most instances, the Company's products are released soon after technological feasibility has been established; therefore, costs incurred subsequent to achievement of technological feasibility are usually not significant.

During the three and nine months ended March 31, 2013, the Company capitalized $0.4 million and $1.6 million of software development costs related to new products, respectively. The software is not yet available for general release to customers; therefore, no amortization expense has been recognized related to these capitalized software costs. The Company did not capitalize any software development costs for the three and nine months ended March 31, 2012.

Amortization of intangible assets for the three months ended March 31, 2013 and 2012 was $2.4 million and $0.9 million, respectively. For the nine months ended March 31, 2013 and 2012, amortization of intangible assets was $7.2 million and $2.2 million, respectively.
