The Company’s contingent consideration liability is accounted for at fair value on a recurring basis and is adjusted to fair value when the carrying value differs from fair value. The categorization of the framework used to measure fair value of the contingent consideration liability is considered Level 3 due to the subjective nature of the unobservable inputs used. The fair values of the contingent consideration liability for Sphere Health Systems, Inc. ("Sphere"), IntraNexus, Inc. ("IntraNexus"), CQI Solutions, Inc. ("CQI"), ViaTrack, and Matrix were estimated based on the probability of achieving certain business milestones and management’s forecast of expected revenues. See Note 3.

The following table presents activity in the Company’s financial assets and liabilities measured at fair value using significant unobservable inputs (Level 3), as of and for the three months endedJune 30, 2012:

Non-Recurring Fair Value Measurements

The Company has certain assets, including goodwill and other intangible assets, which are measured at fair value on a non-recurring basis and are adjusted to fair value only if an impairment charge is recognized. The categorization of the framework used to measure fair value of the assets is considered Level 3 due to the subjective nature of the unobservable inputs used. During the three months endedJune 30, 2012, there were no adjustments to fair value of such assets, except for the intangible assets acquired from Matrix and The Poseidon Group, Inc. ("Poseidon") as discussed further below.
