Fair Value Measurements Fair Value Measurements

The fair value hierarchy is based on inputs to valuation techniques that are used to measure fair value that are either observable or unobservable. Observable inputs reflect assumptions market participants would use in pricing an asset or liability based on market data obtained from independent sources while unobservable inputs reflect a reporting entity’s pricing based upon its own market assumptions.

The fair value hierarchy consists of the following three levels:

Level 1 – Inputs are quoted prices in active markets for identical assets or liabilities.

Level 2 – Inputs are quoted prices for similar assets or liabilities in an active market, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable and market-corroborated inputs which are derived principally from or corroborated by observable market data.

Level 3 – Inputs are derived from valuation techniques in which one or more significant inputs or value drivers are unobservable.

The carrying value of cash and cash equivalents, accounts receivable, accounts payable, current liabilities and the revolving line of credit approximate fair value because of the short maturity of these instruments.

All highly liquid investments with maturities at date of purchase of three months or less are considered to be cash equivalents. Based on their short-term nature, the carrying value of cash equivalents approximate their fair value. As of December 31, 2019, $64.2 million of the Company’s cash and cash equivalents balance related to money-market fund investments and $3.0 million related to fixed time deposits. As of December 31, 2018, $37.7 million of the Company’s cash and cash equivalents balance related to money-market fund investments. These short-term money-market funds and fixed time deposits are considered Level 1 investments.

The Company has a deferred compensation plan, which is funded through COLI policies. The COLI asset is carried at fair value derived from quoted market prices of investments within the COLI policies, which are considered Level 2 inputs. Refer to Note 11, Employee Benefit Plans, for the fair value of the COLI asset as of December 31, 2019 and 2018.

The Company estimates the fair value of each foreign exchange forward contract by using the present value of expected cash flows. The estimate takes into account the difference between the current market forward price and contracted forward price for each foreign exchange contract and applies the difference in the rates to each outstanding contract. Valuations for all derivatives fall within Level 2 of the GAAP valuation hierarchy. The fair value of the Company’s derivative instruments outstanding as of December 31, 2019 was immaterial.

The Company has contingent consideration liabilities related to acquisitions which are measured on a recurring basis and recorded at fair value, determined using the discounted cash flow method. The inputs used to calculate the fair value of the contingent consideration liabilities are considered to be Level 3 inputs due to the lack of relevant market activity and significant
management judgment. An increase in future cash flows may result in a higher estimated fair value while a decrease in future cash flows may result in a lower estimated fair value of the contingent consideration liabilities. Remeasurements to fair value are recorded in adjustment to fair value of contingent consideration in the Consolidated Statements of Operations. Refer to Note 7, Balance Sheet Components, for the estimated fair value of the contingent consideration liabilities as of December 31, 2019 and 2018.

The fair value of the Notes is measured using quoted price inputs. The Notes are not actively traded, and thus the price inputs represent a Level 2 measurement. As the quoted price inputs are highly variable from day to day, the fair value estimates could significantly increase or decrease.

The Notes are carried at their principal amount less unamortized debt discount and issuance costs, and are not carried at fair value at each period end. The original debt discount was calculated at a market interest rate for nonconvertible debt at the time of issuance, which represented a Level 3 fair value measurement. The approximate fair value of the Notes as of December 31, 2019 and 2018 was $195.4 million and $128.3 million, respectively, which is estimated on the basis of inputs that are observable in the market and is considered a Level 2 fair value measurement.
