Loans, Notes, Trade and Other Receivables Disclosure [Text Block] | NOTE 3 – RECEIVABLES The Company has adopted credit policies and standards intended to reduce the inherent risk associated with potential increases in its concentration of credit risk due to increasing trade receivables from sales to owners and users of commercial office facilities and with specifiers such as architects, engineers and contracting firms. Management believes that credit risks are further moderated by the diversity of its end customers and geographic sales areas. The Company performs ongoing credit evaluations of its customers ’ financial condition and requires collateral as deemed necessary. The Company maintains allowances for doubtful accounts for estimated losses resulting from the inability of customers to make required payments. If the financial condition of its customers were to deteriorate, resulting in an impairment of their ability to make payments, additional allowances may be required. As of December 31, 2017, and January 1, 2017, the allowance for bad debts amounted to $3.5 million and $3.8 million, respectively, for all accounts receivable of the Company. Reserves for warranty and returns allowances amounted to $4.1 million and $5.5 million as of December 31, 2017 and January 1, 2017, respectively.
