Fair Value of Financial Instruments
Fair Value of Financial Instruments
The Company’s financial instruments have been recorded at fair value using available market information and valuation techniques.  The fair value hierarchy is based upon three levels of input, which are:
Level 1 − quoted prices in active markets for identical assets or liabilities (observable)
Level 2 − inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities, quoted prices in inactive markets, or other inputs that are observable market data for essentially the full term of the asset or liability (observable)
Level 3 − unobservable inputs that are supported by little or no market activity, but are significant to determining the fair value of the asset or liability (unobservable)
The Company’s financial instruments consist primarily of cash and cash equivalents, trade receivables, trade payables, debt instruments and deferred compensation assets and liabilities. For cash and cash equivalents, trade receivables and trade payables, the carrying amounts of these financial instruments as of 2019 and 2018 were considered representative of their fair values.  The estimated fair value of the Company’s long-term debt and line of credit at 2019 and 2018 was based on variable and fixed interest rates at 2019 and 2018, respectively, for new issues with similar remaining maturities and approximates the respective carrying values at 2019 and 2018. The estimate fair value of the Notes was $102.3 million as of December 31, 2019.
The deferred compensation assets and liabilities primarily relate to the Company’s deferred compensation plan, which allows for pre-tax salary deferrals for certain key employees (see Note 12 – Employees Benefit Plans – of Notes to Consolidated Financial Statements). Changes in the fair value of the deferred compensation liabilities are derived using quoted prices in active markets of the asset selections made by the participants. The deferred compensation liabilities are classified within Level 2, as defined under U.S. GAAP, because their inputs are derived principally from observable market data by correlation to the hypothetical investments. The Company holds insurance investments to partially offset the Company’s liabilities under the deferred compensation plan, which are recorded at fair value each period using the cash surrender value of the insurance investments.
The Company has obligations, to be paid in cash, to the former owners of AccSys, based on the achievement of certain conditions as defined in the definitive agreements (see Note 1 – Summary of Significant Accounting Policies – Contingent Consideration and Note 2 – Acquisitions). During the year ended December 31, 2019 the obligation due to the former owners of Brink was settled in full.
The fair value of this contingent consideration payable, included in other long-term liabilities on the consolidated balance sheets, was estimated using a discounted cash flow method, with significant inputs that are not observable in the market and thus represents a Level 3 fair value measurement as defined in ASC 820, “Fair Value Measurements and Disclosures.” The significant inputs in the Level 3 measurement not supported by market activity included the Company’s probability assessments of expected future cash flows related to the Brink Acquisition during the contingent consideration period, appropriately discounted considering the uncertainties associated with the obligation, and calculated in accordance with the terms of the definitive agreement.  The liabilities for the contingent consideration were established at the time of the acquisition and are evaluated on a quarterly basis based on additional information as it becomes available.  Any change in the fair value adjustment is recorded in the earnings of that period.  Changes in the fair value of the contingent consideration obligations may result from changes in probability assumptions with respect to the likelihood of achieving the various contingent payment obligations. Significant increases or decreases in the inputs noted above in isolation would result in a significantly lower or higher fair value measurement.
The following table presents a summary of changes in fair value of the Company’s Level 3 liabilities that are measured at fair value on a recurring basis (in thousands):
