Derivative Instruments and Hedging Activities Disclosure [Text Block]	K. Derivatives and Hedging We are exposed to gains and losses resulting from fluctuations in foreign currency exchange rates relating to forecasted product sales denominated in foreign currencies and to other transactions of NAIE, our foreign subsidiary. As part of our overall strategy to manage the level of exposure to the risk of fluctuations in foreign currency exchange rates, we may use foreign exchange contracts in the form of forward contracts. To the extent we enter into such contracts, there can be no guarantee any such contracts will be effective hedges against our foreign currency exchange risk. As of March 31, 2023, we had forward contracts designated as cash flow hedges primarily to protect against the foreign exchange risks inherent in our forecasted sales of products at prices denominated in currencies other than the U.S. Dollar. These contracts are expected to be settled through September 2024. For derivative instruments that are designated and qualify as cash flow hedges, we record the effective portion of the gain or loss on the derivative in accumulated other comprehensive income (“OCI”) as a separate component of stockholders’ equity and subsequently reclassify these amounts into earnings in the period during which the hedged transaction is recognized in earnings. For foreign currency contracts designated as cash flow hedges, hedge effectiveness is measured using the spot rate. Changes in the spot-forward differential are excluded from the test of hedge effectiveness and are recorded currently in earnings as revenue. We measure effectiveness by comparing the cumulative change in the hedge contract with the cumulative change in the hedged item. No hedging relationships were terminated as a result of ineffective hedging for the three and nine months ended March 31, 2023 and March 31, 2022. We monitor the probability of forecasted transactions as part of the hedge effectiveness testing on a quarterly basis. During the three and nine months ended March 31, 2023 and March 31, 2022, we did not have any losses or gains related to the ineffective portion of our hedging instruments. As of March 31, 2023, the notional amounts of our foreign exchange contracts designated as cash flow hedges were approximately $24.0 million (EUR 21.4 million). As of March 31, 2023, a net gain of approximately $50,000, offset by $6,000 of deferred taxes, related to derivative instruments designated as cash flow hedges was recorded in OCI. It is expected that $50,000 will be reclassified into earnings in the next 12 months along with the earnings effects of the related forecasted transactions. For foreign currency contracts not designated as cash flow hedges, changes in the fair value of the hedge are recorded directly to foreign exchange gain or loss in other income in an effort to offset the change in valuation of the underlying hedged item. During the three and nine months ended March 31, 2023, we entered into forward contracts in order to hedge foreign exchange risk associated with our lease liability at NAIE, which is denominated in Swiss Francs (CHF). As of March 31, 2023, the notional amounts of our foreign exchange contracts not designated as cash flow hedges were approximately $12.2 million (CHF 11.4 million). We are exposed to interest rate fluctuations related to our $10.0 million Term Note with Wells Fargo, which carries a variable interest rate of 1.80% above the SOFR rolling 30-day average. To manage our exposure to this variable rate, on August 23, 2021, we entered into a floored interest rate swap that fixes our all-in rate on this loan to 2.4% for the first three years of the term loan. Fluctuations in the relation of our contractual swap rate to current market rates are recorded as an asset or liability with an offset to OCI at the end of each reporting period. Interest expense is adjusted for the difference between the actual SOFR spread and the swap contractual rate such that our effective interest expense for each period is equal to our hedged rate of 2.4%.
