Subsequent Events [Text Block]	O. Subsequent Events On July 18, 2023, we entered into a Fourth Amendment to Lease amending and extending the term of the lease of its Vista, California manufacturing facilities. The Fourth Amendment extends the term of the Lease by an additional ten years and five months commencing April 1, 2024. The amended Lease covering two buildings and approximately 162,000 square feet will result in an increase in base rent to $1.50 per square foot, after five free months of base rent beginning at the commencement of the extended term. NAI intends to construct substantial improvements to the facilities including but not limited to installation of an approximately $2.3 million solar electrical generating system on both buildings, and other substantial improvements. Pursuant to the Fourth Amendment, the Landlord will reimburse NAI for up to $1.1 million of these tenant improvements to the buildings. On August 16, 2023, we announced the temporary closure of our new high-speed powder processing facility in Carlsbad, California due to excess inventory on hand at one of our largest customer’s and their efforts to rebalance supply and demand. We expect this facility will re-open and our prior level of operations will resume late in our third fiscal quarter of 2024, but there can be no assurance this customer will resolve its supply and demand issues in the timeframe expected or what level of business we will have with this customer if they purchase from us in the future. Closure of this plant will contribute to an anticipated net loss in the first half of fiscal 2024, net income in the second half, and an overall net loss in fiscal 2024. If this customer is unable to resolve its inventory issues in this timeframe, or our sales forecast is not realized we will likely experience a continuing material decrease in revenues during fiscal year 2024. On September 15, 2023, our Board of Directors adopted a Clawback Policy requiring recoupment of certain executive compensation in the event of an accounting restatement resulting from material noncompliance with financial reporting requirements under the federal securities laws.
