Fair Value Measurements

The Company records its financial assets and liabilities at fair value. The accounting guidance for fair value provides a framework for measuring fair value, clarifies the definition of fair value, and expands disclosures regarding fair value measurements. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability, an exit price, in an orderly transaction between market participants at the reporting date. The accounting guidance establishes a three-tiered hierarchy, which prioritizes the inputs used in the valuation methodologies in measuring fair value:

Level 1 - Quoted prices in active markets for identical assets or liabilities.

Level 2 - Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.
    
The following table summarizes the Company's financial assets and liabilities that are measured at fair value on a recurring basis and are categorized using the fair value hierarchy (in thousands):

On August 1, 2014, the Company completed the acquisition of Treehouse, which the Company accounted for under the purchase method of accounting. The terms of the asset purchase agreement relating to the acquisition provides for contingent consideration up to $2.0 million in cash earn-out payments based on the achievement of certain specified performance metrics through 2015. The estimated fair value of the performance-based contingent consideration was $1.0 million at September 30, 2014, and has been reflected as an other long-term liability. The Company determined the estimated fair value of the liability for the contingent consideration based on a probability-weighted discounted cash flow analysis. In each period, the Company will reassess its current estimates of performance relative to the stated targets and will adjust the liability to the estimated fair value through earnings.

The change in the contingent consideration liability is summarized as follows during the three months ended September 30, 2014 (in thousands):
