The Company periodically evaluates the carrying value of long-lived assets when events or circumstances warrant such a review. The carrying value of a long-lived asset is considered impaired when the estimated realizable value of the asset is less than the carrying value of the asset. In that event, a loss is recognized based on the amount by which the carrying value exceeds the fair value of the long-lived asset. Fair value is determined based on the estimated realizable value of the long-lived asset.

The Company recorded an asset impairment charge of $0.6 million against a specific group of machinery and equipment during the three and nine months ended September 30, 2015. This specific group of machinery and equipment is used to perform carrier screening testing which the Company currently outsources to our partners. The impairment charge was recorded to reflect reductions in the estimated realizable value of the machinery and equipment as a result of planning for its sale in the secondary market. The Company recorded the total impairment charge of $0.6 million in cost of product revenue. The Company has classified the impaired machinery and equipment as held for sale at the estimated realizable value of $0.5 million.
