Restructuring and Related Activities [Abstract]
Operating Expenses	Operating Expenses During fiscal 2026 and 2025, we recorded a net expense of $1,162,000 and $2,117,000, respectively, related to CEO transition costs. Such activities in both fiscal years consisted primarily of net legal expenses related to a former CEO and expense related to a sign-on bonus for our current CEO, and severance costs and third party CEO search firm expenses related to a former CEO in fiscal 2025. During fiscal 2025, we incurred $2,682,000 of proxy solicitation costs, consisting principally of legal and advisory fees. In November 2024, we entered into a cooperation agreement (the “Cooperation Agreement”) with Fred Kornberg, Michael Porcelain and Oleg Timoshenko (collectively the “Investor Group”). Pursuant to the Cooperation Agreement, our Board appointed Michael J. Hildebrandt to serve on the Board and agreed to nominate, support and recommend Mr. Hildebrandt for election at our Fiscal 2024 Annual Meeting of Stockholders (the "2024 Annual Meeting"). Also, we agreed not to renominate two incumbent directors for election at the 2024 Annual Meeting and the Investor Group agreed to withdraw its nomination of candidates for election to the Board at the 2024 Annual Meeting to, instead, support our slate of directors for election. Pursuant to the Cooperation Agreement, we and the Investor Group will cooperate to identify an additional candidate to be appointed to the Board at a later date as an independent director. In September 2025, we provided notice to the Investor Group regarding our renomination of Mr. Hildebrandt at the Fiscal 2025 Annual Meeting of Stockholders. Accordingly, the Cooperation Agreement was extended until 30 days prior to the nomination deadline of our Fiscal 2026 Annual Meeting of Stockholders. During fiscal 2026 and 2025, we incurred $9,984,000 and $10,016,000, respectively, of restructuring costs primarily focused on legal and other expenses related to strategic alternatives and divestiture activities, as well as other initiatives to streamline our operations, align our cost structure with our future anticipated business and improve our liquidity.
