Fair Value Disclosures [Abstract] |
Fair Value Measurements | Fair Value Measurements ASC Topic 820, Fair Value Measurements and Disclosures (ASC 820), provides a framework for measuring fair value and requires expanded disclosures regarding fair value measurements. ASC 820 defines 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 on the measurement date. ASC 820 also establishes a fair value hierarchy, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. ASC 820 describes three levels of inputs that may be used to measure fair value: Level 1: Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities. The Company’s Level 1 assets are investments in money market mutual funds and United States treasuries. Level 2: Quoted prices for similar assets or liabilities in active markets; or observable prices that are based on observable market data, based on directly or indirectly market-corroborated inputs. The Company has no Level 2 assets or liabilities. Level 3: Unobservable inputs that are supported by little or no market activity, and are developed based on the best information available given the circumstances. The Company has no Level 3 assets. Assets and liabilities measured at fair value are based on the valuation techniques identified in the table below. The following tables present financial assets and liabilities at March 31, 2021 and December 31, 2020 for which the Company measures fair value on a recurring basis, by level, within the fair value hierarchy:
March 31, 2021 | Total |  | Level 1 |  | Level 2 |  | Level 3 |  | Valuation Technique
Assets |  |  |  |  |  |  |  |  |
Money market mutual funds | $ | 25,143 |  |  | $ | 25,143 |  |  | $ | — |  |  | $ | — |  |  | (a)
December 31, 2020 | Total |  | Level 1 |  | Level 2 |  | Level 3 |  | Valuation Technique
Assets |  |  |  |  |  |  |  |  |
Money market mutual funds | $ | 20,142 |  |  | $ | 20,142 |  |  | $ | — |  |  | $ | — |  |  | (a)
United States treasuries | 4,999 |  |  | 4,999 |  |  | — |  |  | — |  |  | (a)
(a)Market approach—prices and other relevant information generated by market transactions involving identical or comparable assets. The carrying amount of certain financial instruments approximates fair value due to their short-term, highly liquid nature. These instruments include cash and cash equivalents, accounts receivable, accounts payable, and accrued expenses. The carrying amount of the Company's operating and financing lease liabilities approximates fair value based on currently available quoted rates of similarly structured borrowings. Assets Measured and Recorded at Fair Value on a Nonrecurring Basis The Company's non-financial assets, such as goodwill, intangible assets, and other long-lived assets resulting from business combinations, are measured at fair value using income approach valuation methodologies at the date of acquisition and subsequently re-measured if an impairment exists. During 2020, the Company recorded an impairment charge of $10,490 to goodwill and intangible assets. There was no additional impairment of the Company's non-financial assets noted as of March 31, 2021. The Company does not have any liabilities that are recorded at fair value on a non-recurring basis.
