Fair Value Disclosures [Abstract]  
FAIR VALUE MEASUREMENTS FAIR VALUE MEASUREMENTSAt March 31, 2021 and December 31, 2020, the Company had derivative assets totaling $2.8 million and $2.2 million, respectively, and derivative liabilities totaling $12.4 million and $23.3 million, respectively. The Company has limited involvement with derivative financial instruments and therefore does not present all the required disclosures in tabular format. The fair values of the interest rate swap agreements, the cross currency swap agreements, and the foreign currency forward contracts that economically hedge short-term intercompany balances are estimated based upon inputs from current valuation information obtained from dealer quotes and priced with observable market assumptions and
appropriate valuation adjustments for credit risk. The Company has evaluated the valuation methodologies used to develop the fair values by dealers in order to determine whether such valuations are representative of an exit price in the Company’s principal market. In addition, the Company uses an internally developed model to perform testing on the valuations received from brokers. The Company has also considered both its own credit risk and counterparty credit risk in determining fair value and determined these adjustments were insignificant at March 31, 2021 and December 31, 2020.
The estimated fair value of the contingent consideration obligation of $13.5 million relating to the PendoTECH acquisition was determined using a Monte Carlo simulation based on the Company's forecast of future financial results. The fair value measurements are based on significant inputs not observable in the market and thus represent a Level 3 measurement.
Under U.S. GAAP, fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. A fair value measurement consists of observable and unobservable inputs that reflect the assumptions that a market participant would use in pricing an asset or liability.
A fair value hierarchy has been established that categorizes these inputs into three levels:
Level 1: Quoted prices in active markets for identical assets and liabilities
Level 2: Observable inputs other than quoted prices in active markets for identical assets and liabilities
Level 3: Unobservable inputs
The following table presents the Company’s assets and liabilities, which are all categorized as Level 2 and are measured at fair value on a recurring basis at March 31, 2021 and December 31, 2020. The Company does not have any assets or liabilities which are categorized as Level 1 or Level 3, with the exception of the PendoTECH contingent consideration described above.

The Company had $18.0 million and $14.3 million of cash equivalents at March 31, 2021 and December 31, 2020, respectively, the fair value of which is determined using Level 2 inputs, through quoted and corroborated prices in active markets. The fair value of cash equivalents approximates cost.
The fair value of the Company's debt exceeds the carrying value by approximately $39.6 million as of March 31, 2021. The fair value of the Company's fixed interest rate debt was estimated using Level 2 inputs, primarily utilizing discounted cash flow models based on estimated current rates offered for similar debt under current market conditions for the Company.
