Fair Value Measurements

The Company considers fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the measurement date. The Company utilizes the following three-level fair value hierarchy to establish the priorities of the inputs used to measure fair value:

•Level 1 — Quoted prices in active markets for identical assets or liabilities.

•Level 2 — Observable inputs other than quoted market prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data.

•Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. This includes certain pricing models, discounted cash flow methodologies and similar techniques that use significant unobservable inputs.

The following table presents the Company’s financial assets and liabilities that were accounted for at fair value on a recurring basis, excluding assets related to the Company’s defined benefit pension plans, classified by the level within the fair value hierarchy (in thousands):

Acquisition-related contingent consideration

On April 20, 2016 (the "Jaybird Acquisition Date"), the Company acquired all of the equity interest of Jaybird, LLC (“Jaybird”). The acquisition-related contingent consideration liability arising from the Jaybird acquisition represents the future potential earn-out payments of up to $45.0 million based on the achievement of certain net revenue targets over approximately a two year period. If the net revenue targets are met, the Company will pay a maximum of $25.0 million and $20.0 million in fiscal years 2018 and 2019, respectively. The fair value of the earn-out as of the Jaybird Acquisition Date was $18.0 million, which was determined by using a Monte Carlo Simulation that includes significant unobservable inputs such as a risk-adjusted discount rate of 16% and projected net sales of Jaybird over the earn-out period. The fair value is remeasured at each reporting period at the estimated fair value based on the inputs on the date of remeasurement, with the change in fair value recognized as "change in fair value of contingent consideration for business acquisition" in the operating expense section in the condensed consolidated statements of operations. Projected net sales are based on the Company's internal projections, including analysis of the target markets. In October 2017, the Company and the sellers of Jaybird entered into an agreement fully, irrevocably and unconditionally releasing the Company from the earn-out rights and payments in exchange for $5.0 million in cash, which approximates the fair value of the contingent consideration as of September 30, 2017 and the expected cash payment is included in the accrued and other current liabilities.

Investment Securities

The marketable securities for the Company's deferred compensation plan are recorded at a fair value of $17.6 million and $15.0 million, respectively, as of September 30, 2017 and March 31, 2017, based on quoted market prices. Quoted market prices are observable inputs that are classified as Level 1 within the fair value hierarchy. Unrealized trading gains / (losses) related to trading securities for the three and six months ended September 30, 2017 and 2016 were not material and are included in other income (expense), net in the Company's condensed consolidated statements of operations.

Assets Measured at Fair Value on a Nonrecurring Basis

The Company’s non-marketable cost method investments, and non-financial assets, such as goodwill, intangible assets and property, plant and equipment, are recorded at fair value only upon initial recognition or if an impairment is recognized. There were no material impairments of long-lived assets during the three and six months ended September 30, 2017 or 2016.

Non-marketable cost method investments. These investments are classified as Level 3 due to the absence of quoted market prices, the inherent lack of liquidity, and the fact that inputs used to measure fair value are unobservable and require management's judgment. When certain events or circumstances indicate that impairment may exist, the Company revalues the investments using various assumptions, including the financial metrics and ratios of comparable public companies.

The primary investment included in non-marketable investments is the Company’s investment in Series A Preferred Stock of Lifesize Inc. ("Lifesize") recorded at the fair value of $5.6 million on the date of the Lifesize divestiture.

The aggregate recorded amount of cost method investments included in other assets as of September 30, 2017 and March 31, 2017 was $7.1 million and $7.4 million, respectively.
