Debt Disclosure [Abstract] |
BANK LINE OF CREDIT [Text Block] | BANK LINE OF CREDIT: On July 27, 2016, the Company entered into a credit agreement with a bank (the "Credit Agreement") that provides the Company with a $75.0 million revolving line of credit to use for general corporate purposes with a $20.0 million sub-limit for the issuance of standby and trade letters of credit. The Company’s ability to borrow under the revolving line of credit is conditioned upon the Company’s compliance with specified covenants, including reporting and financial covenants, primarily a minimum cash requirement and a debt to earnings ratio. The Credit Agreement terminates on July 26, 2019; all advances under the revolving line of credit will become due on such date, or earlier in the event of a default. As of December 31, 2017, the Company was compliant with all covenants and had no amount outstanding under the Credit Agreement.
