LEASES AND COMMITMENTS [Abstract] |
LEASES AND COMMITMENTS [Text Block] | 12. LEASES AND COMMITMENTS: Facilities and Leases The Company owns its main executive, administrative, manufacturing and technical offices in San Jose, California. The Company also owns a research and development facility in New Jersey, a design center in Germany and a test facility in Switzerland. The Company’s leases consist of operating leases for administrative office spaces, research-and-development facilities and sales offices in various countries around the world. Effective January 1, 2019, the Company adopted Accounting Standards Update 2016-02, Leases (Topic 842), using the optional transition method. The Company determines if an arrangement is a lease at inception. Some lease agreements contain lease and non-lease components, which are accounted for as a single lease component. Total lease expense was $2.7 million, $2.5 million and $2.2 million in the years ended December 31, 2020, 2019 and 2018, respectively, while short-term and variable lease expenses were not material during these periods. Balance sheet information related to leases was as follows:

​ Initial lease terms are determined at commencement and may include options to extend or terminate the lease when it is reasonably certain the Company will exercise the option. Remaining lease terms range from one to eight years, some of which include options to extend for up to six years, and some of which include options to terminate within one year. Leases with an initial term of twelve months or less are not recorded on the balance sheet. As the Company’s leases do not provide an implicit rate, the present value of future lease payments is determined using the Company’s incremental borrowing rate based on information available at commencement date. ​
