(5)Long-term investments with a carrying amount of $489 were recorded at their fair value of $0, resulting in an impairment charge of $489 as a part of investment and other gains for the year ended December 31, 2024.
The fair value of the Level 2 certificates of deposit is based on the discounted value of contractual cash flows. The discount rate is the rate offered by the financial institution.
The fair values of the Level 3 PropTech convertible trading debt securities were derived using a discounted cash flow model utilizing a probability-weighted expected return method based on the probabilities of different potential outcomes for the convertible trading debt securities.
The long-term investments are based on NAV per share provided by the partnerships based on the indicated market value of the underlying assets or investment portfolio. In accordance with Subtopic 820-10, these investments are not classified under the fair value hierarchy disclosed above because they are measured at fair value using the NAV practical expedient.
The fair value of the derivative embedded within the convertible debt and the fair value of the convertible debt itself was derived using a binomial lattice valuation model. The derivative has been classified as Level 3. Change in the fair value of the derivative embedded within the convertible debt is presented in the consolidated statements of operations. The value of the embedded derivative is contingent on changes in interest rates, the Company’s stock price, stock price volatility, and the Company’s dividend yield. The Company’s stock price, volatility, and dividend yield are based on market observable inputs. The interest rate component of the value of the note is computed by calibrating the yield as of the issuance date, such that the value of the convertible note is equal to the principal net of the original issue discount. This yield is adjusted by the change in spreads from the discount curve equivalent to the Company’s implied credit rating.
The changes in the fair value of the Level 3 assets as of December 31, 2025 were as follows:

In addition to assets and liabilities that are recorded at fair value on a recurring basis, the Company is required to record assets and liabilities at fair value on a nonrecurring basis. Generally, assets and liabilities are recorded at fair value on a nonrecurring basis because of impairment charges. As discussed in Note 1(x), the Company recorded an impairment of fixed assets of $2,275 for the year ended December 31, 2025 on the consolidated statements of operations. The Company had no nonrecurring nonfinancial assets subject to fair value measurements as of December 31, 2025 and 2024.

About Fair Value Disclosures

Fair value disclosures classify all assets and liabilities measured at fair value into a three-level hierarchy: Level 1 (quoted market prices), Level 2 (observable inputs like yield curves), and Level 3 (unobservable inputs requiring management estimates). The proportion of Level 3 assets directly reflects how much of the balance sheet depends on internal models rather than market evidence.

Key signals: a growing Level 3 balance relative to total fair-value assets increases valuation uncertainty and earnings volatility risk. Watch for transfers between levels — assets moving from Level 2 to Level 3 often signal deteriorating market liquidity. Unrealized gains and losses on Level 3 positions flow through earnings or other comprehensive income, so large swings deserve scrutiny. For financial institutions, examine the sensitivity disclosures that show how Level 3 valuations change under alternative assumptions. Compare the fair value of debt against its carrying amount to gauge hidden leverage.
