Financial Instruments | Financial Instruments The following table presents the carrying amounts and estimated fair values of our other financial instruments by hierarchy level as of December 31, 2018 and 2017.
The fair values of financial instruments not included in this table are estimated to be equal to their carrying values as of December 31, 2018 and 2017. We estimate the fair value of our 2023 Convertible Notes based on their last actively traded prices. The fair value of our debt is classified within Level 2 of the fair value hierarchy because it is traded in less active markets. We estimate the fair value of acquisition-related contingent consideration using a probability-weighted discounted cash flow model. This fair value estimate represents a Level 3 measurement as it is based on significant inputs not observed in the market and reflect our own assumptions. The significant unobservable inputs used in the fair value measurements of our acquisition-related contingent consideration are our measures of the future profitability and related cash flows and discount rates. The fair value of the contingent consideration is reassessed at each reporting period by the Company based on additional information as it becomes available. Any change in the fair value of an acquisition’s contingent consideration liability results in a remeasurement gain or loss that is recorded in “Selling, general and administrative expenses” on the Consolidated Statements of Comprehensive Income. During the year ended December 31, 2018, there was no change in the estimated fair value of future expected contingent consideration payments. During the years ended December 31, 2017 and 2016, we recorded $0.7 million and $1.4 million in expense related to increases in the fair value of future expected contingent consideration payments, respectively. |
