Derivatives and Fair Value [Text Block]	Note 12 - Derivative Instruments; Fair Value The Company accounts for derivative instruments in accordance with U.S. GAAP, which requires that all derivative instruments be recognized on the balance sheet at fair value. We may enter into interest rate swaps to fix the interest rate on a portion of our variable interest rate debt to reduce the potential volatility in our interest expense that would otherwise result from changes in market interest rates. Our derivative instruments are recorded at fair value and are included in accrued liabilities of our consolidated balance sheet. Our accounting policies for these instruments are based on whether they meet our criteria for designation as hedging transactions, which include the instrument’s effectiveness, risk reduction and, in most cases, a one-to-one matching of the derivative instrument to our underlying transaction. As of June 30, 2021, we had no such instrument.
