The Company uses the market approach technique to value its financial assets and liabilities. The Company’s financial assets and liabilities carried at fair value include, when applicable, investments in common stock and derivative instruments used to hedge the Company’s interest rate risks. The fair value of the Company’s investment in common stock of Harvard Apparatus Regenerative Technologies (“HRGN” formerly known as Biostage, Inc.) (see Note 16 for information regarding the HRGN Settlement) was based on the closing price as quoted on the OTCQB Marketplace at the reporting date. The fair value of the Company’s interest rate swap agreements was based on SOFR-yield curves at the reporting date.
