Subsequent Events [Abstract]
Subsequent events	Subsequent eventsThe Company has evaluated subsequent events through the filing of this Annual Report on Form 10-K, and determined that there have been no events that have occurred that would require adjustments to our disclosures in the consolidated financial statements.Since the beginning of 2020, the COVID-19 coronavirus outbreak which originated in mainland China has significantly impacted the global and U.S. economies. As a result of the spread of the COVID-19 coronavirus, economic uncertainties have arisen which are likely to negatively impact the results of our operations.

The entire disclosure for significant events or transactions that occurred after the balance sheet date through the date the financial statements were issued or the date the financial statements were available to be issued. Examples include: the sale of a capital stock issue, purchase of a business, settlement of litigation, catastrophic loss, significant foreign exchange rate changes, loans to insiders or affiliates, and transactions not in the ordinary course of business.
