5.   Financial Instruments and Fair Value Measurement

The carrying values of cash and cash equivalents, restricted cash, accounts receivable, accounts payable and term note payable in the Company’s consolidated balance sheets approximated their fair values as of June 30, 2023 and 2022 due to their short-term nature. The carrying value of the convertible promissory note receivable, term note payable and finance lease obligations approximated fair value as of June 30, 2023 and 2022 as the interest rates related to the financial instruments approximated market.

The Company accounts for its investments in debt securities at fair value. The following provides a description of the three levels of inputs that may be used to measure fair value under the standard, the types of plan investments that fall under each category, and the valuation methodologies used to measure these investments at fair value:

•Level 1 – Inputs are based upon unadjusted quoted prices for identical instruments in active markets.

The Company’s fixed assets and amortizable intangible assets are measured at fair value on a nonrecurring basis; that is, these assets are not measured at fair value on an ongoing basis, but are subject to fair value adjustments in certain circumstances, such as when there is evidence of impairment.

The Company initially marketed the CDMO business and during the second quarter of Fiscal year 2023, changed its strategy to selling the stand-alone CDMO assets. These assets were assessed for impairment and the analysis resulted in the expected future cash flows from the sale of the Facility and equipment falling below its current carrying value. The Company utilized a market approach, using independent third-party appraisals, including comparable assets, in addition to bids received from prospective buyers, to estimate the fair value of the Facility and equipment. As a result, the carrying value of the Facility and equipment was reduced to their estimated fair values of $16,350,000 and $2,100,000, respectively. In the second quarter of Fiscal year 2023, impairment charges were recorded in discontinued operations under general and administrative expense of $6,300,000 and $11,300,000 for the Facility and equipment, respectively. In the first quarter of Fiscal 2024, the Company entered into an agreement for the building for $17.25 million, and an additional impairment of $0.3 million was recorded in the fourth quarter of Fiscal 2023 to reflect the agreed upon sales price less estimated costs to sell.  The carrying amount of the CDMO fixed assets after impairment on June 30, 2023 was $16.1 million. The machinery and equipment were sold during the third quarter of Fiscal year 2023.

The following table shows the fair value of the Company's fixed assets included in Current Assets Held For Sale measured at fair value on a non-recurring basis as of June 30, 2023 (amounts in thousands):

During the second quarter of Fiscal year 2023, the Company re-evaluated its business strategy and reviewed its product portfolio. After such review, the Company identified intellectual property, patent and licenses that would no longer be utilized and therefore were fully impaired (Level 3).
