There were no transfers of assets or liabilities between Level 1, Level 2 and Level 3 categories of the fair value hierarchy during the three and six month periods ended June 30, 2015 and the year ended December 31, 2014.
The Company used Level 1 inputs to determine the fair value of a portion of its cash equivalents, which primarily consist of funds held in a money market account, and as such, the carrying value of such cash equivalents approximates fair value. As of June 30, 2015 and December 31, 2014, the carrying value of these cash equivalents was $178.1 million and $3.1 million, respectively.
The Company assesses the fair value of contingent consideration to be settled in cash related to acquisitions using the Monte Carlo Simulation Model for the royalty earn-out portion of the contingent liability. This is a Level 3 measurement. Significant assumptions used in the measurement include future royalty payments and the discount rate associated with the potential volatility of the acquired business. The Company recorded no changes to the fair value of the contingent consideration for the three months ended June 30, 2014. Due to changes in the estimated future royalty payments and a shorter discounting period, the fair value of the contingent consideration liabilities changed, resulting in a $42,000 loss recorded to cost of sales in the Consolidated Statements of Operations during the six months ended June 30, 2014. The Company recorded no changes to the fair value of the contingent consideration liabilities during the three and six month periods ended June 30, 2015.
Changes in estimated fair value of contingent consideration liabilities from December 31, 2014 through June 30, 2015 are as follows (in thousands):
