Fair Value Measurements

Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability, or the exit price in an orderly transaction between market participants on the measurement date. A three-level hierarchy is used for fair value measurements based upon the observability of the inputs to the valuation of an asset or liability as of the measurement date. Level 1 measurements consist of unadjusted quoted prices in active markets for identical assets or liabilities. Level 2 measurements include quoted prices in markets that are not active or model inputs that are observable either directly or indirectly for substantially the full term of the asset or liability. Level 3 measurements include significant unobservable inputs. A financial instrument’s level within the hierarchy is based on the highest level of any input that is significant to the fair value measurement. Following is a description of our valuation methodologies used to estimate the fair value of our assets and liabilities.

Assets and Liabilities that are Measured at Fair Value on a Nonrecurring Basis

The Company’s non-financial assets such as intangible assets and property, plant and equipment are recorded at fair value when an impairment is recognized or at the time acquired in a business combination. The determination of the estimated fair value of such assets required the use of significant unobservable inputs which would be considered Level 3 fair value measurements. As of March 31, 2018, there were no indicators that would require an impairment of intangible assets or property, plant and equipment.

Assets and Liabilities that are Measured at Fair Value on a Recurring Basis

The Company measures certain assets and liabilities at their estimated fair value on a recurring basis, including cash and cash equivalents, our contingent consideration obligations associated with the acquisition of CDI and investments in trading securities (described further below under the “Trading Equity Securities” heading). See Note 15 - Litigation, Commitments and Contingencies for additional information on the CDI contingent consideration. The following table provides information by level for assets and liabilities that are measured at fair value on a recurring basis as of March 31, 2018 and December 31, 2017:

Trading Equity Securities

On February 8, 2016, the Company entered into a subscription agreement with Clinton Lighthouse Equity Strategies Fund (Offshore) Ltd. (“Clinton Lighthouse”). Clinton Lighthouse is a market neutral fund which provides daily liquidity to its investors. The short term investment was classified as a trading security as we expect to be actively managing this investment at all times with the intention of maximizing our investment returns. Income or loss including unrealized gains and losses associated with this trading security is recorded as a component of “Other income (expense), net” in our Condensed Consolidated Statements of Operations and purchases or sales of this security are reflected as operating activities in our Condensed Consolidated Statements of Cash Flows. The short term investment balance in Clinton Lighthouse decreased from $0.4 million as of December 31, 2017 to $0.2 million as of March 31, 2018 due to redemptions during the period. See Note 16 - Related Party Transactions for more information.

In June 2017, we launched the GBAM Fund, which focuses on technology-driven quantitative strategies and other alternative investment strategies. The short term investments within the GBAM Fund were classified as trading securities as we expect to be actively managing the GBAM Fund at all times with the intention of maximizing our investment returns. Income or loss associated with these trading securities is recorded as a component of “Net gain (loss) from GBAM Fund activities” in our Condensed Consolidated Statements of Operations and purchases or sales of these securities are reflected as operating activities in our Condensed Consolidated Statements of Cash Flows. See Note 14 - Segment Information for additional information.

In connection with the adoption of ASU No. 2015-07, Fair Value Measurement (Topic 820), FASB Accounting Standards Codification 820 - Fair Value Measurement and Disclosures no longer requires investments for which fair value is determined based on practical expedient reliance to be reported utilizing the fair value hierarchy. As of March 31, 2018 and December 31, 2017, our short term investments in Clinton Lighthouse and the GBAM Fund were fair valued using the net asset value as practical expedient and has been removed from the fair value hierarchy table above.

Other Assets and Liabilities

The carrying value of accounts receivable and accounts payable approximate their fair values due to the short term duration of these items.
