Schedules of Concentration of Risk, by Risk Factor | The following table presents the Company’s product revenue by geographic locations. The geographic information includes product revenue from the Company’s domestic and international customers based on the customers’ requested delivery locations, except for certain cases in which the customer directed the Company to deliver its products to a location that differs from the known ultimate location of use. In such cases, the ultimate location of use rather than the delivery location is reflected in the table.
