Subsequent Events [Abstract]
Subsequent Event	13. Subsequent Event In December 2019, a novel strain of coronavirus (“COVID-19”) was reported in Wuhan, China. The World Health Organization has declared COVID-19 to constitute a global pandemic. On March 19, 2020 the Governor of Pennsylvania declared a health emergency and issued an order to close all nonessential businesses until further notice. Our operations are deemed to be essential and thus we remain open. However, disruptions to our business operations could occur as a result of quarantines of employees and suppliers in areas affected by the outbreak, facility closures, and travel and logistics restrictions in connection with the outbreak. While we expect this matter to negatively impact its results of operations, cash flow and financial position, the related financial impact cannot be reasonably estimated at this time.

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.
