In October 2020, the Company purchased preferred equity securities of Neo Medical SA, a privately held Swiss-based company developing a new generation of products for spinal surgery ("Neo Medical"), for consideration of $5.0 million. The Company also entered into a Convertible Loan Agreement pursuant to which the Company loaned Neo Medical CHF 4.6 million, or $5.0 million at the date of issuance (the “Convertible Loan”). In October 2021, the Company entered into a second Convertible Loan Agreement (the “Second Convertible Loan” and together with the Convertible Loan, the “Neo Medical Convertible Loans”), pursuant to which the Company loaned Neo Medical an additional CHF 0.6 million, or $0.7 million as of the date of issuance.

The preferred equity securities are recorded in other long-term assets and are considered an investment that does not have a readily determinable fair value. As such, the Company measures this investment at cost, less any impairment, plus or minus changes resulting from observable price changes in orderly transactions for identical or similar investments of the same issuer.

The table below presents a reconciliation of the beginning and ending balances of the Company’s investment in Neo Medical preferred equity securities:


(Unaudited, U.S. Dollars, in thousands)	2023		2022
Fair value of Neo Medical preferred equity securities at January 1	$	6,084	$	5,413
Conversion of loan into preferred equity securities		—		671
Fair value of Neo Medical preferred equity securities at September 30	$	6,084	$	6,084
Cumulative unrealized gain on Neo Medical preferred equity securities	$	413	$	413

The Company elected to convert the Second Convertible Loan into shares of Neo Medical’s preferred equity securities in January 2022. The Convertible Loan is recorded in other long-term assets as an available for sale debt security as of September 30, 2023. The fair value of the Convertible Loan is based upon significant unobservable inputs, including the use of option-pricing models, Monte Carlo simulations for certain periods, and a probability-weighted discounted cash flow model, requiring the Company to develop its own assumptions. Therefore, the Company categorized this investment as a Level 3 financial asset.

Some of the more significant unobservable inputs used in the fair value measurement of the Convertible Loan include applicable discount rates, implied volatility, the likelihood and projected timing of repayment or conversion, and projected cash flows in support of the estimated enterprise value of Neo Medical. Holding other inputs constant, changes in these assumptions could result in a significant change in the fair value of the Convertible Loan. If the amortized cost of the Convertible Loan exceeds its estimated fair value, the security is deemed to be impaired, and must be evaluated for the recognition of a credit loss. As of September 30, 2023, the Company has not recognized any credit loss related to the Convertible Loan.

The following table provides a reconciliation of the beginning and ending balances of the Convertible Loans, measured at fair value using significant unobservable inputs (Level 3):


(Unaudited, U.S. Dollars, in thousands)	2023		2022
Fair value of Neo Medical Convertible Loans at January 1	$	7,140	$	7,148
Interest recognized in interest income, net		367		326
Foreign currency remeasurement recognized in other expense, net		54		(437	)
Unrealized gain (loss) recognized in other comprehensive loss		109		(766	)
Conversion of Second Convertible Loan into preferred equity securities		—		(671	)
Fair value of Neo Medical Convertible Loans at September 30	$	7,670	$	5,600

Until August 2022, the Company held an investment in common stock of Bone Biologics Inc. (“Bone Biologics”, NASDAQ: BBLG), a developer of orthobiologic products. The Company disposed of its remaining holdings in Bone Biologics equity securities during the third quarter of 2022.

Other investments represent assets and investments recorded at fair value that are not deemed to be material for disclosure on an individual basis. The fair value of these assets is based upon significant unobservable inputs, such as probability-weighted discounted cash flow models, requiring the Company to develop its own assumptions. Therefore, the Company has categorized these assets as Level 3 financial assets. As of September 30, 2023, this balance was classified within other long-term assets.

The Company recognized a contingent consideration obligation in connection with the acquisition of Spinal Kinetics in 2018. The fair value of the remaining Spinal Kinetics contingent consideration, attributable to a revenue-based milestone, was concluded to be zero as of September 30, 2023, as the Company did not achieve the milestone prior to April 30, 2023, the end of the measurement period for achieving such milestone.

The following table provides a reconciliation of the beginning and ending balances for the Spinal Kinetics contingent consideration measured at estimated fair value using significant unobservable inputs (Level 3):

In connection with the Merger, the Company assumed a contingent consideration obligation under a purchase agreement between SeaSpine and Lattus Spine LLC ("Lattus") executed in December 2022. Under the terms of the agreement, the Company may be required to make installment payments at certain dates based on future net sales of certain products (the "Lateral Products").

The estimated fair value of the Lattus contingent consideration as of the closing of the Merger, January 5, 2023, was $11.2 million. The estimated fair value of the Lattus contingent consideration is determined using a Monte Carlo simulation and a discounted cash flow model requiring significant inputs which are not observable in the market. The significant inputs include assumptions related to the timing and probability of certain product launch dates, estimated future sales of the products, revenue risk-adjusted discount rate, revenue volatility, and discount rates matched to the timing of payments. The following table provides a reconciliation of the beginning and ending balances for the Lattus contingent consideration measured at estimated fair value using significant unobservable inputs (Level 3):
