Fair Value Disclosures [Abstract] |
Fair value measurements | Fair Value Measurements Fair value is defined as the amount that would be received for selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The Company categorizes financial assets and liabilities into the three levels of the fair value hierarchy. The hierarchy prioritizes the inputs to valuation techniques used to measure fair value and bases categorization within the hierarchy on the lowest level of input that is available and significant to the fair value measurement.
• | Level 1 — Quoted prices in active markets for identical assets or liabilities;
• | Level 2 — Observable inputs other than Level 1, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities; and
• | Level 3 — Significant unobservable inputs that are supported by little or no market activity or that are based on the reporting entity’s assumptions about the inputs.
Fair Value of Other Financial Instruments The carrying amounts of certain financial instruments, including cash and cash equivalents, accounts receivable, accounts payable, and accrued expenses, approximate fair value due to the short-term nature of these accounts. The Company had total cash of $97.5 million, which consisted of cash equivalents of $46.6 million in a government money market account and cash deposits of $45.2 million in an interest bearing demand deposit account and $5.7 million in operating cash accounts, at June 30, 2019, and $3.0 million, which consisted of no cash equivalents and cash deposits of $3.0 million in operating cash accounts, at December 31, 2018. The carrying amount and estimated fair value of the Company’s long-term debt are as follows (in thousands):
| June 30, 2019 |  | December 31, 2018
| Carrying Amount |  | Fair Value |  | Carrying Amount |  | Fair Value
Borrowings under Credit Facility | — |  |  | — |  |  | 49,731 |  |  | 49,731 |
The carrying amount of borrowings under the Credit Facility approximates its fair value because the interest rates are variable. Assets Measured at Fair Value on a Nonrecurring Basis The Company’s non-financial assets, including property and equipment, goodwill, and other intangible assets are measured at fair value on a non-recurring basis and are subject to fair value adjustment in certain circumstances. During the three months ended June 30, 2018, the Company recorded an impairment of $37.2 million for goodwill in the Energy Chemistry Technologies reporting unit. No impairments of any of these assets were recognized during the three and six months ended June 30, 2019.
