5. In-Process Research and Development and Goodwill

The fair values of in-process research and development (IPR&D) acquired in business combinations are capitalized. The Company utilizes the "income method," which applies a probability weighting that considers the risk of development and commercialization to the estimated future net cash flows that are derived from projected sales revenues and estimated costs. These projections are based on factors such as relevant market size, patent protection, historical pricing of similar products and expected industry trends. The estimated future net cash flows are then discounted to the present value using an appropriate discount rate. This analysis is performed for each project independently. These assets are treated as indefinite-lived intangible assets until completion or abandonment of the projects, at which time the assets are amortized over the remaining useful life or written off, as appropriate. IPR&D intangible assets which are determined to have a decline in their fair value are adjusted downward and an expense is recognized as part of the general and administrative expenses in the Consolidated Statements of Operations. These are tested at least annually or when a triggering event occurs that could indicate a potential impairment.

Goodwill represents excess consideration in a business combination over the fair value of identifiable net assets acquired. Goodwill is not amortized, but is subject to impairment testing at least annually or when a triggering event occurs that could indicate a potential impairment. The Company determines whether goodwill may be impaired by comparing the fair value of the reporting unit, calculated as the product of shares outstanding and the share price as of the end of a period, to its carrying value. No goodwill impairment has been recognized as of March 31, 2014 or 2013. The Company has determined that it has only one reporting unit, which includes the acquired Molecular Insight.

The following tables reflect the components of the finite lived intangible assets as of March 31, 2014 and December 31, 2013:

As of March 31, 2014	Gross Amount		Accumulated Amortization		Net Carrying Value
Finite lived intangible assets	$	21	$	3	$	18
Total	$	21	$	3	$	18

As of December 31, 2013	Gross Amount		Accumulated Amortization		Net Carrying Value
Finite lived intangible assets	$	21	$	2	$	19
Total	$	21	$	2	$	19

The weighted-average remaining life of the finite lived intangible assets was approximately five years at March 31, 2014 and December 31, 2013.

Amortization expense is calculated on a straight-line basis over the estimated useful life of the asset. Amortization expense for the three months ended March 31, 2014 was $1. Estimated amortization expense related to intangible assets existing as of March 31, 2014 is approximately $4 annually for each of the succeeding five years.
