Other Investments [Abstract]

Variable Interest Entity Disclosure [Text Block]

Investment in Variable Interest Entity

In July 2018, the Company purchased $3.0 million in preferred stock of a privately held corporation with a complementary business line. The Company does not have power over the activities that most significantly impact the economic performance of this variable interest entity and is, therefore, not the primary beneficiary. In October 2019, the Company purchased an additional $4.0 million in preferred stock upon the exercise of an option by the variable interest entity. The Company has an option to purchase all the outstanding common shares issued by the variable interest entity on the fifth anniversary of the initial preferred stock purchase.

Additionally, the Company has extended a $2.5 million revolving line of credit to the variable interest entity to fund its inventory purchases. The Company's investment and amounts loaned under the line of credit are recorded in other long-term assets on the consolidated balance sheet.
