Fair Value Disclosures [Abstract] |
FAIR VALUE MEASUREMENTS | 4. FAIR VALUE MEASUREMENTS Fair value is defined as the price that would be received from selling an asset or paid to transfer a liability (i.e., the “exit price”) in an orderly transaction between market participants at the measurement date. In determining fair value, the use of various valuation methodologies, including market, income, and cost approaches is permissible. We consider the principal or most advantageous market in which it would transact and assumptions that market participants would use when pricing the asset or liability. Fair Value Hierarchy. The accounting guidance for fair value measurements establishes a fair value hierarchy that requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. There are three levels of inputs that may be used to measure fair value based on the reliability of inputs. A financial instrument’s categorization within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. Our assessment of a particular input to the fair value measurement requires judgment and may affect their placement within the fair value hierarchy levels. We have categorized our cash equivalents and investments within the fair value hierarchy as follows: Level 1 – applies to assets or liabilities for which there are quoted prices in active markets for identical assets or liabilities. These Level 1 assets include our money market accounts, which are classified as cash equivalents. We have categorized our cash equivalents as Level 1 assets as there are quoted prices in active markets for identical assets or liabilities. Level 2 – applies to assets or liabilities for which there are inputs other than quoted prices that are observable for the asset or liability such as quoted prices for similar assets or liabilities in active markets; quoted prices for identical assets or liabilities in markets with insufficient transactions (less active markets); or model-derived valuations in which significant inputs are observable or can be derived principally from, or corroborated by observable market data. At June 30, 2025 and 2024, we have categorized our investments in marketable equity securities as Level 2 assets and we utilized both a protective put option and a time-adjusted discount for the lack of marketability valuation method to estimate fair value. Level 3 – applies to assets or liabilities for which there are unobservable inputs to the valuation methodology that are significant to the measurement of the fair value of the assets or liabilities. We held no Level 3 assets or liabilities at June 30, 2025 or 2024.

Marketable equity securities at June 30, 2025 and 2024 had an aggregate cost basis of $3,551,000 and $3,964,000, respectively. Both current and long-term marketable equity securities include equity securities of public companies that are thinly traded. We classified certain investments as long term in nature because even if we decide to sell the stocks, we may not be able to sell our position within one year. At June 30, 2025, the investments included net unrealized gains of $3.3 million (gross unrealized gains of $3.5 million offset by gross unrealized losses of $213,000). At June 30, 2024, the investments included net unrealized gains of $1.8 million (gross unrealized gains of $2.1 million offset by gross unrealized losses of $261,000). Of the total marketable equity securities at June 30, 2025 and 2024, $1.0 million and $987,000, respectively, represent an investment in the common stock of Air T, Inc. Two of our Board members, Messrs. Swenson and Cabillot, are also board members of Air T, Inc. and both either individually or through affiliates own an equity interest in Air T, Inc. Mr. Swenson, our Chairman, also serves as the chief executive officer and chairman of Air T, Inc. Another of our Board members is employed by Air T as its Chief of Staff. The shares have been purchased through 10b5-1 Plans that, in accordance with our internal policies regarding the approval of related-party transactions, were approved by our then three Board members that are not affiliated with Air T, Inc. On October 6, 2023, in conjunction with the execution of a supply agreement with Monogram Technologies, Inc., formerly Monogram Orthopaedics Inc. (“Monogram”), we exercised a warrant to purchase common stock of Monogram (the “Monogram Warrant”) in full in cash totaling $1,250,000 and received 1,828,551 shares of Monogram common stock (NasdaqCM: MGRM). Additionally, in June 2025 we exercised additional warrants in full in cash totaling $900,000 and received an additional 85,705 shares of common stock and 298,122 shares of Series D Preferred Stock. On July 14, 2025, the Series D preferred stock converted into the same number of common shares pursuant to the terms of the underlying certificate. The fair value of the Monogram common stock and preferred stock is reflected in marketable equity securities – short term in the tables above. Our Chief Executive Officer, Mr. Van Kirk, is also a Monogram board member. We invest surplus cash from time to time through our Investment Committee, which is comprised of one management director, Mr. Van Kirk, and two non-management directors, Mr. Cabillot and Mr. Swenson, who chairs the committee. Both Messrs. Cabillot and Swenson are active investors with extensive portfolio management expertise. We leverage the experience of these committee members to make investment decisions for the investment of our surplus operating capital or borrowed funds. Additionally, many of our securities holdings include stocks of public companies that either Messrs. Swenson or Cabillot or both may own from time to time either individually or through the investment funds that they manage, or other companies whose boards they sit on, such as Air T, Inc.
