Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	4. Fair Value of Financial Instruments The fair value of financial instruments is determined based on assumptions that market participants would use when pricing an asset or liability at the balance sheet date. Certain assets are categorized based on the following fair value hierarchy of market participant assumptions: Level 1 — Unadjusted quoted prices in active markets that are accessible at the measurement date for identical assets or liabilities. Level 2 — Inputs, other than quoted prices in active markets, that are observable either directly or indirectly. Level 3 — Prices or valuation techniques that require inputs that are both significant to the fair value of the asset or liability and supported by little or no market activity. The Company uses observable market data when available, and minimizes the use of unobservable inputs when determining fair value As of March 31, 2020, the Company had $84.1 million, in financial assets held in money market accounts and U.S. treasury bills, all of which were classified as Level 1 in the fair value hierarchy. The Company measured these assets at fair value. The Company classified these assets as Level 1 because the values of these assets are determined using unadjusted quoted prices in active markets for identical assets. As of March 31, 2020 and December 31, 2019, the Company did not have any assets or liabilities classified as Level 2 or Level 3 in the fair value hierarchy.
